Full textAbstract:
The author presents a feature-guided convolution method for rendering a 3D triangular mesh. In Their work, they compute feature directions on the vertices of a mesh and generate noise on the faces of a mesh. After projecting the directions and noise into 2D image space, the author executes convolution to render the mesh. They used three feature directions: a principal direction, the tangent of an isocurve of view-dependent features, and the tangent of an isophote curve. By controlling the value of noise, the author can produce several non-photorealistic rendering effects such as pencil drawing and hatching. This rendering process is temporally coherent and can therefore be used to create artistic styled animations.

Despite the potential obstacle represented by the blood–brain barrier for extravasating malignant cells, metastases are more frequent than primary tumors in the central nervous system. Not only tightly interconnected endothelial cells can hinder metastasis formation, other cells of the brain microenvironment (like astrocytes and microglia) can also be very hostile, destroying the large majority of metastatic cells. However, malignant cells that are able to overcome these harmful mechanisms may benefit from the shielding and even support provided by cerebral endothelial cells, astrocytes and microglia, rendering the brain a sanctuary site against anti-tumor strategies. Thus, cells of the neurovascular unit have a Janus-faced attitude towards brain metastatic cells, being both destructive and protective. In this review, we present the main mechanisms of brain metastasis formation, including those involved in extravasation through the brain vasculature and survival in the cerebral environment.

Mobile games and graphics are popular because un-tethered computing is convenient and ubiquitous entertainment is compelling. However, rendering graphics on mobile devices faces challenges due to limited system resources, such as battery energy, and low memory and disk space. Real time frame rates, low energy consumption and high image quality are all desirable attributes of interactive mobile graphics; however, achieving these objectives is conflicting. For instance, increasing mesh resolutions improves rendered image quality but consumes more battery energy. Therefore, the authors propose a mobile graphics heuristic to minimize energy consumption while maintaining acceptable image quality and interactive frame rates. Over the lifetime of a mobile graphics application, scene complexity, animation paths, user interactivity and other elements all change its CPU and resource demands. In this regard, a heuristic that dynamically changes scene mesh LoDs and amount of CPU timeslices allotted to the mobile graphics application is presented to select optimal operating conditions that balance rendering speed, energy conservation and image quality. Additionally, a workload predict model is proposed so that the heuristic can monitor both application workload and the availability of resources of mobile devices periodically, while adaptively determining how much resources will be allocated to applications.

This paper employs a new technology for modeling textured 3D faces. 3D faces can either be generated automatically from one or more photographs, or modeled directly through an intuitive user interface. Users are assisted in two key problems of computer-aided face modeling. It presents two algorithms for 3D face modeling from an image sequence. The first method works by creating an initial estimate using multiframe structure from motion (SfM) reconstruction framework, which is refined by comparing against a generic face model. The comparison is carried out using an energy-function optimization strategy. Results of 3D reconstruction algorithm are presented. The second method presented reconstructs a face model by adapting a generic model to contours of a face over all the frames of an image sequence. The algorithm for pose estimation and 3D face reconstruction relies solely on contours and the system does not require knowledge of rendering parameters (e.g. light direction and intensity). Results relying on finding accurate point correspondences across frames is presented.

Full textAbstract:
This study seeks to demonstrate that the Pauline phrase πίστις Χριστοῦ is best understood grammatically as the ‘Christ-faith’ in accordance with the so-called ‘third view’, where ‘faith’ is taken to mean a system or set of beliefs, and ‘Christ’ qualifies what the system is about. I argue that the grammar disallows the meaning ‘faith in Christ’ where Christ is the object of one’s ‘trust’, since objective genitives can only mean ‘belief of something (to be true)’, as is shown by an analysis of the data in the NT and in Harrisville 1994; 2006. Additionally, the subjective genitive rendering often fails to make sense within the literary context and faces its own grammatical difficulties. Drawing on work from theoretical linguistics in lexical semantics and syntax, I show that the third view meaning, translated as the ‘Christ-faith’, is the most likely rendering given the context of each of the passages, the Greek case system and the meaning of the noun πίστις as used in the NT and other Koine Greek writings.

Full textAbstract:
Two new hydrated multicomponent crystals of zwitterionic 2-aminonicotinic acid with maleic and fumaric acids have been obtained and thoroughly characterized by a variety of experimental (X-ray analysis and terahertz Raman spectroscopy) and theoretical periodic density functional theory calculations, followed by Bader analysis of the crystalline electron density) techniques. It has been found that the Raman-active band in the region of 300 cm−1 is due to the vibrations of the intramolecular O-H...O bond in the maleate anion. The energy/enthalpy of the intermolecular hydrogen bonds was estimated by several empirical approaches. An analysis of the interaction networks reflects the structure-directing role of the water molecule in the examined multicomponent crystals. A general scheme has been proposed to explain the proton transfer between the components during the formation of multicomponent crystals in water. Water molecules were found to play the key role in this process, forming a “water wire” between the COOH group of the dicarboxylic acid and the COO– group of the zwitterion and the rendering crystal lattice of the considered multicomponent crystals.

Full textAbstract:
A sample of 183 medical students completed the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT V2.0). Scores on the test were examined for evidence of reliability and factorial validity. Although Cronbach's alpha for the total scores was adequate (.79), many of the scales had low internal consistency (scale alphas ranged from .34 to .77; median = .48). Previous factor analyses of the MSCEIT are critiqued and the rationale for the current analysis is presented. Both confirmatory and exploratory factor analyses of the MSCEIT item parcels are reported. Pictures and faces items formed separate factors rather than loading on a Perception factor. Emotional Management appeared as a factor, but items from Blends and Facilitation failed to load consistently on any factor, rendering factors for Emotional Understanding and Emotional Facilitation problematic.

Full textAbstract:
Cluster analysis faces two problems in high dimensions: the “curse of dimensionality” that can lead to overfitting and poor generalization performance and the sheer time taken for conventional algorithms to process large amounts of high-dimensional data. We describe a solution to these problems, designed for the application of spike sorting for next-generation, high-channel-count neural probes. In this problem, only a small subset of features provides information about the cluster membership of any one data vector, but this informative feature subset is not the same for all data points, rendering classical feature selection ineffective. We introduce a “masked EM” algorithm that allows accurate and time-efficient clustering of up to millions of points in thousands of dimensions. We demonstrate its applicability to synthetic data and to real-world high-channel-count spike sorting data.

L10-ordered FePt and CoPt (collectively called L10- Fe ( Co ) Pt in this review) have become potential materials for future ultrahigh density perpendicular magnetic recording (PMR) media due to their high magnetocrystalline anisotropy, rendering small grains with high thermal stability. However, PMR media using such high anisotropy faces the well-known trilemma issues among thermal stability, signal-to-noise ratio (SNR), and writability. This paper will provide an overview of the impact of L10- Fe ( Co ) Pt on overcoming the superparamagnetic limit and balancing the trilemma issues for ultrahigh density PMR media. Here the research and development of L10- Fe ( Co ) Pt materials will be presented, from the perspectives of enhancing thermal stability, SNR and writability. Furthermore, we will provide some combined approaches to tackle the challenges in balancing the trilemma issues, focusing on materials engineering.

Full textAbstract:
In view of the slow speed and poor effect of real-time rendering of large-scale reservoir geological grid model, a new grid model hidden algorithm is proposed by analyzing the Eclipse reservoir grid model storage format, grid model representation, and cell sorting rule, which optimizes the original grid data and improves the rendering speed of reservoir grid model. The algorithm in this paper eliminates hidden points and faces according to the topological relationship of the grid, and finally, only the visible point and face data are extracted as the final visual input data. Through the realization of 3D visualization software of reservoir geological model and well trajectory, the correctness and efficiency of the hidden algorithm are verified. In the software, firstly, the number of display grids is effectively reduced by preprocessing, and the 3D graphics technology of WPF and helix is adopted to realize the high-efficiency display of reservoir grids. The comparison test of different scale reservoir models shows that the method can reduce the point and surface data by more than 85% and shows that the speed optimization effect is significant. The 3D display function realizes the interactive functions such as roaming, zooming, and viewpoint switching of the reservoir model, truly reveals again the geological environment and borehole information of underground drilling, which is helpful for drilling interpretation and decision-making, provides a reasonable drilling tracking geological target drilling scheme for the drilling process, and realizes the seamless connection of geological engineering integration.

Image rendering of shadow faces a problem existed for a long time,that is the contradiction of quality and performance. Variant algorithms are presented to ameliorate this problem,shadow map is the one which is representative for that. Even though shadow maps have been widely used for the shadow of Three-dimensional scene,some imperfection still exist in this method like aliasing problem.So,the focus of the paper is introduce an algorithm which layering the data sets of the large scale building's shadow rapidly and intelligently based shadow map. First, we ascertain the fragment which create the shadow by shadow mapping's two scan. Second, we process the float data in the depth buffer by using uniformization and render the two depth data in the texture.Then use Gauss Filter to blur.Finally,use the algorithm of BIRCH cluster the uniformization data to improve the obscure and tweened effect.This method brings reduction of aliasing problem with low overhead as well as performance to a certain extent .

Full textAbstract:
With the advent of the deep learning method, portrait video stylization has become more popular. In this paper, we present a robust method for automatically stylizing portrait videos that contain small human faces. By extending the Mask Regions with Convolutional Neural Network features (R-CNN) with a CNN branch which detects the contour landmarks of the face, we divided the input frame into three regions: the region of facial features, the region of the inner face surrounded by 36 face contour landmarks, and the region of the outer face. Besides keeping the facial features region as it is, we used two different stroke models to render the other two regions. During the non-photorealistic rendering (NPR) of the animation video, we combined the deformable strokes and optical flow estimation between adjacent frames to follow the underlying motion coherently. The experimental results demonstrated that our method could not only effectively reserve the small and distinct facial features, but also follow the underlying motion coherently.

Full textAbstract:
In medical research, a scenario often entertained is randomized controlled 22 factorial design with a binary outcome. By utilizing the concept of potential outcomes, Dasgupta et al. proposed a randomization-based causal inference framework, allowing flexible and simultaneous estimations and inferences of the factorial effects. However, a fundamental challenge that Dasgupta et al.’s proposed methodology faces is that the sampling variance of the randomization-based factorial effect estimator is unidentifiable, rendering the corresponding classic “Neymanian” variance estimator suffering from over-estimation. To address this issue, for randomized controlled 22 factorial designs with binary outcomes, we derive the sharp lower bound of the sampling variance of the factorial effect estimator, which leads to a new variance estimator that sharpens the finite-population Neymanian causal inference. We demonstrate the advantages of the new variance estimator through a series of simulation studies, and apply our newly proposed methodology to two real-life datasets from randomized clinical trials, where we gain new insights.

Full textAbstract:
The arousal theory of color proposes that red is associated with arousal. Research on the color-in-context theory, in turn, states that the context in which red is perceived influences its valence-related meaning and behavioral responses to it. This study faces and integrates these theories by examining the influence of red on both arousal and valence perceptions of test-relevant and neutral stimuli, rendering a color 2 (red vs. blue) × context 2 (test vs. neutral) between-subjects design. Participants rated different pictures regarding their arousal and valence component, respectively. In line with the assumptions of both theories, red increased arousal perceptions of stimuli irrespective of their valence but a context × color interaction was found for valence perceptions: for participants viewing test-relevant pictures, red increased their perceptions of negativity compared to neutral pictures. The present study shows that both theories are actually compatible when differentiating the arousal and valence component.

Full textAbstract:
The literary translator taking on the task of rendering a major work of European poetry into contemporary English verse faces several challenges in regard to poetic form, including the problem of finding forms in English-language poetry today for conventions derived from foreign literary traditions and the need to engage the historical context of the work without sounding archaic. If a translation is to transmit the essence of a canonical text from a century or more ago, including its formal dimension, it must both convey what is distinct about the original, moving the reader toward the fundamental foreignness of the text, as Schleiermacher advised, and speak to the reader in the language of our time, because a translation that is not recognizable as good poetry in contemporary terms will not be read. This essay will compare the particular strategies of three successful but quite different contemporary translations of canonical works: Richard Howard’s versijon of Baudelaire’s Flowers of Evil, Robert Pinsky’s translation of The Inferno, and Seamus Heaney’s Beowulf.

This study presents the analysis of realism of portraiture in the context of physical anthropology. Standard descriptive traits such as the development of the upper eyelid fold, nasal profi le, etc., were scored on 120 portraits. To examine the accuracy of artistic rendition, these traits were assessed on 30 pairs of portraits of the same persons painted by different artists, and on 30 pairs of portraits versus photographs of the same persons. For each trait, the mean difference of scores was calculated. The mean differences are within the scoring error, indicating the artists’ high accuracy in rendering facial features. Next, four composite portraits were generated, two relating to 15th–16th century French aristocrats, and two to the 15th–17th century Dutch population, mainly that of Amsterdam. Composite portraits for every geographic region are virtually identical, suggesting that they represent a specifi c population rather than just a total of\individual data. Also, even though painters might be somewhat imprecise in depicting individual faces, these inaccuracies are leveled off in composite representations. In sum, portraiture is a very informative source of anthropometric information.

As the present collection of articles makes clear, there is no shortage of interpretations of or reactions to Borat: Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan. While nothing drains the laughter out of a joke faster than academic analysis, these articles succeed in raising differing, thought-provoking perspectives on the meaning and significance of one of the biggest cultural phenomena of 2006. And although their methodological and analytical perspectives diverge, these articles share at least one trait in common. Each author faces grappling with the relationship between the Kazakhstan of Sacha Baron Cohen's imagination and, dare I say, the “real Kazakhstan,” a real place inhabited by real people, existing in real time and space. I do not dispute the subjectivity of that reality, but the acceptance of the premise that Kazakhstan and Kazakhstanis in fact exist is essential to my argument, which seeks not to place the country and its people on a level playing field with their hyperreal corollary, but to underscore the power relations that come into play when eroding or rendering insignificant the line between them.

Full textAbstract:
Screening programs for genetic and metabolic diseases such as haemoglobinopathies, thalassemias and diabetes are a worldwide problem that faces economic and technological limitations. This is mainly because genetic and metabolic tests are too expensive and time consuming to be implemented. MALDI-ToF mass spectrometry is a rapid and affordable high throughput technique with diagnostic potential for these diseases but still constrained by the timing and complexity of data analysis. To overcome this technological limitation, we developed a fully automated software solution in our MALDI-ToF instrument towards the detection of haemoglobinopathies, thalassemias and diabetes on one blood card sample. The software was tested for its efficiency and accuracy on 171 blood samples rendering 30-fold faster analysis with less bias and rounding errors in comparison with the manual approach. In this study, we identified the variability associated with the disease biomarkers in healthy individuals and successfully applied predictive models to detect blood abnormalities. Taken together, we demonstrated in this study that population screening of multiple blood disorders is made possible using MALDI-ToF technology in combination with automated software tools.

Full textAbstract:
The performances of the current face recognition systems suffer heavily from the variations in lighting. To deal with this problem, this paper presents an illumination normalization approach by relighting face images to a canonical illumination based on the harmonic images model. Benefiting from the observations that human faces share similar shape, and the albedos of the face surfaces are quasi-constant, we first estimate the nine low-frequency components of the illumination from the input facial image. The facial image is then normalized to the canonical illumination by re-rendering it using the illumination ratio image technique. For the purpose of face recognition, two kinds of canonical illuminations, the uniform illumination and a frontal flash with the ambient lights, are considered, among which the former encodes merely the texture information, while the latter encodes both the texture and shading information. Our experiments on the CMU-PIE face database and the Yale B face database have shown that the proposed relighting normalization can significantly improve the performance of a face recognition system when the probes are collected under varying lighting conditions.

Full textAbstract:
The criteria of true neutrality would infer that the neutrino is not a truly neutral particle and thus would imply that ββoν decay is forbidden, in agreement with the absence of any evidence of this process so far. Any fundamental interaction admits at least one truly neutral particle as messenger. Materialization through SM interactions corresponds to the creation of a pair of baryon antibaryon or lepton antilepton. These pairs have the same quantum numbers as those of the neutral messenger responsible for their creation. No net change of baryon number or lepton number could be obtained through materialization. But, we know that our present Universe is composed of matter and is electrically neutral. This implies that the number of protons is strictly equal to the number of electrons. A possible scenario is put forward to account for these two fundamental experimental facts. The principle of complementarity would explain the exact balance of protons and electrons. Baryogenesis and leptogenesis would be the two faces of the same phenomenon. This scenario is compatible with the absence of ββoν decay and of proton decay and it does not require the unification of forces. This model could explain the asymmetric but nevertheless electrically neutral Universe; however, it could not account for the numerical value of the tiny excess of matter over antimatter in the early Universe. This value would be incidental. MC force with a structure analogous to that of weak force would ensure the neutrality of our Universe without requiring the strict matter-antimatter symmetry, rendering thus the concept of anti-Universe superfluous.

Full textAbstract:
The subjective impressions of pedestrians are necessary in order to decide on the appropriate colour of light to be used for street lighting. Therefore, a pilot project aimed to compare subjective evaluations of the sidewalk illumination under two street lighting installations, realised by LEDs of 3000 K (warm white) and 4000 K (neutral white), was recently conducted in Belgrade. Both installations had comparable sidewalk illuminances as well as other relevant photometric parameters. The evaluation was done through a questionnaire. A group of 139 (61 male and 78 female) respondents, all of them university students, was asked to grade both lighting installations for the sidewalk light intensity, the appearance of human faces, the colour of light and the colour rendering as well as the overall impression. According to the median values, the 3000 K LED installation was considered better than the 4000 K installation for all aspects assessed as well as the overall impression. Although the survey results convincingly showed a preference for 3000 K LEDs for this comparison, additional research is needed using a more representative sample of people and a wider range of locations before a definite conclusion can be reached.

AbstractObjectiveA better understanding of the pathophysiology of suicidal behaviour (SB) may enable the discovery of more specific treatments and a better identification of vulnerable patients. The vulnerability to SB appears to be underlied by genetic factors coding for traits rendering the individual less able to cope with stressing situations, and more likely to be engaged in a suicidal process.MethodDuring the recent years, neuroscientific studies begun to identify potential endophenotypes.ResultsWe have shown that disadvantageous decision making (DM) was involved in the vulnerability to SB. DM impairment appears to be independent of comorbid psychiatric disorders, associated with emotional dysregulation (i.e. affective lability trait and skin conductance responses), and modulated by serotonergic genotypes associated with SB. In recent fMRI studies, the region that is likely involved in DM, is overactivited in response to angry faces, suggesting a higher sensitivity to specific negative social stimuli. Deficit in risk evaluation and excessive response to specific emotional stimuli may represent key processes in the vulnerability to SB.ConclusionsThese potential endophenotypes may represent future relevant markers of vulnerability for the identification of vulnerable patients, and relevant targets for the development of new treatments.

Full textAbstract:
In the context of CAD CAM CAE (Computer-Aided Design, Manufacturing and Engineering) and Additive Manufacturing, the computation of level sets of closed 2-manifold triangular meshes (mesh slicing) is relevant for the generation of 3D printing patterns. Current slicing methods rely on the assumption that the function used to compute the level sets satisfies strong Morse conditions, rendering incorrect results when such a function is not a Morse one. To overcome this limitation, this manuscript presents an algorithm for the computation of mesh level sets under the presence of non-Morse degeneracies. To accomplish this, our method defines weak-Morse conditions, and presents a characterization of the possible types of degeneracies. This classification relies on the position of vertices, edges and faces in the neighborhood outside of the slicing plane. Finally, our algorithm produces oriented 1-manifold contours. Each contour orientation defines whether it belongs to a hole or to an external border. This definition is central for Additive Manufacturing purposes. We set up tests encompassing all known non-Morse degeneracies. Our algorithm successfully processes every generated case. Ongoing work addresses (a) a theoretical proof of completeness for our algorithm, (b) implementation of interval trees to improve the algorithm efficiency and, (c) integration into an Additive Manufacturing framework for industry applications.

AbstractIn this article, I argue that much of the discourse observable within the UN constitutes neither unnecessary and unproductive ‘talk’ nor efforts to convince outside audiences of its legitimacy, but actually a form of institutional self-legitimation that is key to its ability to function. Using the case of the UN's Department of Peacekeeping Operations (DPKO), I show that because the organisation has a multifaceted organisational identity, it faces situations where it is forced to choose between multiple but equally appropriate courses of action, and it uses self-legitimation alongside other mechanisms to overcome these tensions. I specify three sets of circumstances in which this occurs, showing how DPKO uses discourse that simplifies and exceptionalises in a bid to reconcile or downplay these contradictions and reassert a cohesive and legitimate organisational identity internally. This simplification and exceptionalisation in turn serve an enabling function, allowing DPKO to continue operating in conditions of complexity by decreasing risk aversion and instilling a deep sense of professional loyalty in staff. At the same time, such discursive processes are costly and may entrench inefficient practices, rendering the effects of self-legitimising discourse paradoxical: they may enable action, but they reduce the efficiency and effectiveness of that action.

This paper intends to explicate the present framework of legal and social policies in India, which govern urban development. The research is directed towards contemplating the progress of sustainable urbanism in India in achieving the goals of the 2030 Agenda for Sustainable Development. Overcrowding, rise in the number of informal settlers and unplanned development are the most prominent multi- faceted issues that India faces in the present day. A comprehensive analysis of urban development policies, environmental legislation, property laws and information laws have been discussed in order to exhibit the lacunae in the legal system which has slowed down the process of sustainable urban development in India. It is not only the policies, but also an array of problems that, have affected urban development in metropolitan cities, semi- urban regions and transitioning rural areas rendering them to be unsustainable. Therefore, this paper envisages and suggests solutions in tackling problems in legal and social policies that would make sustainable urbanism conducive and successful in India. An attempt has also been made to display how completely sustainable urban spaces would look in India. Analytical, Comparative and Doctrinal methods of research have been utilized to conduct the research.Keywords: Development, Local Self Government, Policies, Sustainable, India

An important question for understanding the neural basis of problem solving is whether the regions of human prefrontal cortices play qualitatively different roles in the major cognitive restructuring required to solve difficult problems. However, investigating this question using neuroimaging faces a major dilemma: either the problems do not require major cognitive restructuring, or if they do, the restructuring typically happens once, rendering repeated measurements of the critical mental process impossible. To circumvent these problems, young adult participants were challenged with a one-dimensional Subtraction (or Nim) problem [Bouton, C. L. Nim, a game with a complete mathematical theory. The Annals of Mathematics, 3, 35–39, 1901] that can be tackled using two possible strategies. One, often used initially, is effortful, slow, and error-prone, whereas the abstract solution, once achieved, is easier, quicker, and more accurate. Behaviorally, success was strongly correlated with sex. Using voxel-based morphometry analysis controlling for sex, we found that participants who found the more abstract strategy (i.e., Solvers) had more gray matter volume in the anterior medial, ventrolateral prefrontal, and parietal cortices compared with those who never switched from the initial effortful strategy (i.e., Explorers). Removing the sex covariate showed higher gray matter volume in Solvers (vs. Explorers) in the right ventrolateral prefrontal and left parietal cortex.

The mobile devices are termed to highly potential due to their capability of rendering services without being plugged to the electric grid. These device are becoming highly prominent due to their constant progress in computing as well as storing capacities and as they are very much closer to the users. Despites its advantages it still faces many problems due to the load balancing and energy consumption due to its limited battery limited and storage availability as some applications or the video downloading requires high storage facilities consuming majority of the energy in turn reducing the performance of the mobile devices. So as to improve the performance and the capability of the mobile devices the mobile cloud computing that integrates the mobile devices with the cloud paradigm has emerged as a promising paradigm. This enables the augmentation of the local resources for the mobile devices to enhance its capabilities in order to improve its functioning. This is basically done by proper offloading and resource allocation. The proposed method in the paper utilizes the optimal offloading strategy (Single and double strand offloading) and follows an Ant colony optimization based resource allocation for improving the functioning the mobile devices in terms of energy consumption and storage.

Faces are one of the most important means of communication for humans. For example, a short glance at a person’s face provides information about his or her identity and emotional state. What are the computations the brain uses to acquire this information so accurately and seemingly effortlessly? This article summarizes current research on computational modeling, a technique used to answer this question. Specifically, my research tests the hypothesis that this algorithm is tasked with solving the inverse problem of production. For example, to recognize identity, our brain needs to identify shape and shading features that are invariant to facial expression, pose, and illumination. Similarly, to recognize emotion, the brain needs to identify shape and shading features that are invariant to identity, pose, and illumination. If one defines the physics equations that render an image under different identities, expressions, poses, and illuminations, then gaining invariance to these factors can be readily resolved by computing the inverse of this rendering function. I describe our current understanding of the algorithms used by our brains to resolve this inverse problem. I also discuss how these results are driving research in computer vision to design computer systems that are as accurate, robust, and efficient as humans.

After a half century of exploration, the Malay Basin, a mature hydrocarbon province in SE Asia, faces common challenge that most of the conventional structural reservoirs have been drilled out. As a result, the high-risk stratigraphic traps are considered as viable alternative to boost the dwindling oil reserves. In Y field, the discovery of Early Miocene Group I meander belt channel sands outside the low-relief anticlinal closure is seemed to have made substantial contributions to the later oil production. This sparks the inspiration to develop a practical workflow in visualizing the subtle, yet productive channel systems through integration of multidisciplinary datasets. Results have proven that the co-rendering of multi-attributes could effectively delineate the channel edges and reflection strength of sand bodies. Moreover, through the application of neural network techniques on the extracted waveform shape of seismic attribute, a supervised hierarchical lithofacies map was generated. This can help to create a better linkage between the seismic waveform patterns and lithological details of subsurface features. Wireline log analysis was also performed to verify the hydrocarbon potential of Group I sands. This integrated approach may adopted as a reliable best practice in near-field exploration program, especially in proving up the channel-sand stratigraphic play.

Background.Many studies have explored associations between depression and facial emotion recognition (ER). However, these studies have used various paradigms and multiple stimulus sets, rendering comparisons difficult. Few studies have attempted to determine the magnitude of any effect and whether studies are properly powered to detect it. We conducted a meta-analysis to synthesize the findings across studies on ER in depressed individuals compared to controls.Method.Studies of ER that included depressed and control samples and published before June 2013 were identified in PubMed and Web of Science. Studies using schematic faces, neuroimaging studies and drug treatment studies were excluded.Results.Meta-analysis of k = 22 independent samples indicated impaired recognition of emotion [k = 22, g = −0.16, 95% confidence interval (CI) −0.25 to −0.07, p < 0.001]. Critically, this was observed for anger, disgust, fear, happiness and surprise (k's = 7–22, g's = −0.42 to −0.17, p's < 0.08), but not sadness (k = 21, g = −0.09, 95% CI −0.23 to +0.06, p = 0.23). Study-level characteristics did not appear to be associated with the observed effect. Power analysis indicated that a sample of approximately 615 cases and 615 controls would be required to detect this association with 80% power at an alpha level of 0.05.Conclusions.These findings suggest that the ER impairment reported in the depression literature exists across all basic emotions except sadness. The effect size, however, is small, and previous studies have been underpowered.

Introduction: The Nigerian health sector faces several challenges especially during economic recession. These encumbrances have led to low productivity, worsened out-of-pocket expenditure with its attendant "health shock” and poor service delivery. Methodology: A didactic empirical literature review of articles bordering on key terminologies in the title was perused to guide this article. Results Economic recession hampers productivity of both professional personnel and the government in rendering services to the populace on one hand while it may be difficult for the people to access care on the other hand. These bring to the fore, the problems of escalated prices of drugs, low patronage of accredited hospitals, rapid migration of professionals in search of “greener pastures”, and increase in morbidity and mortality in the populace. When these occur, to achieve health for all and Universal Health Coverage becomes a mirage. Discussion: Prospects and pragmatic solutions have been suggested such as funding and financing mechanisms especially Health Insurance Schemes, limiting of medical tourisms to only when it is expressly needed, adequate remuneration of health workers, healthy government policies with policy direction, and needs assessment among other solutions. Conclusion: Healthcare during recession will be better improved when economic indicators are thematically addressed to yield palpable impacts as these will go a long way to alleviate the dwindling health care delivery in a recessed economy.

Full textAbstract:
Since the migrant surge in 2015, social inclusion has become a crucial issue to be addressed effectively by the European Union, given that 39% of the population born outside of the EU member states faces the risk of poverty or social exclusion. Adding to that, the COVID-19 pandemic has severely affected migrant households worldwide, rendering migrant integration an urgent matter for national governments. Discrimination, racism, xenophobia, and radicalization are all societal threats emerging in periods of massive migrant flows and need appropriate policy measures to be employed in migrant host countries to tackle them. This paper suggests the integration of a multiple criteria decision analysis method, namely PROMETHEE, for policy making with regard to migrant social exclusion. In light of previous research findings and the recent release of the Migrant Integration Policy Index 2020, the authors argue that the method proposed could help policy makers to evaluate the effectiveness of the implemented policies, spot the discrepancies between policies and policy outcomes, and motivate knowledge sharing among the EU member states. The findings include a ten-year comparative list of the EU member states (2010–2019) driven by social inclusion indicators for the foreign-born (non-EU-born) population. The results are rather sensitive to changes in the data utilized but they provide an overall comparative picture of social inclusion policy effectiveness in the EU during the past decade.

The article deals with the analysis of lexical, semantic and grammatical levels of the novels’ translations «Les gens heureux lisent et boivent du café» and «La vie est facile, ne t’inquiète pas» by Anese Martin-Lugan into Ukrainian, made by Leonid Kononovich. Particular attention is paid to reproducing the gender aspects of the original works. The need to render the images raises a number of difficulties that the translator faces. Anese Martin-Lugan’s novels are full of examples of using different stylistic devices. The peculiarities of the translation of texts with means of expressiveness from French into Ukrainian with the use of certain translational transformations are examined. In general, metaphors are translated into the Ukrainian language: by a dictionary analogue, by a metaphorical word with the other image, by a metaphoric word with more expressive image. The first attempt was made to analyze gender reproduction in the translation of hero’s language, who is a representative of nonstandard sexual orientation. The lexical and grammatical transformations to reproduce the features of the author’s style are highlighted. It gives conclusions that the minor inaccuracies in the case of non-reproduction of lexical-grammatical and stylistic features of the author’s individual style become much more meaningful when considering their gender components. These observations indicate a certain asymmetry enables to apply gender asymmetry as manipulation, deforming strategies and tactics of translation, and sometimes in case of discrepancy between the original text and translation in terms of analyzing its gender characteristics. It is established that, without gender adequacy, the translated text loses the appropriate completeness of reproduction of the author’s image and the meanings generated by the text.

Abstract BACKGROUND: Brain surgery faces important challenges when trying to achieve maximum tumor resection while avoiding postoperative neurological deficits. OBJECTIVE: For surgeons to have optimal intraoperative information concerning white matter (WM) anatomy, we developed a platform that allows the intraoperative real-time querying of tractography data sets during frameless stereotactic neuronavigation. METHODS: Structural magnetic resonance imaging, functional magnetic resonance imaging, and diffusion tensor imaging were performed on 5 patients before they underwent lesion resection using neuronavigation. During the procedure, the tracked surgical tool tip position was transferred from the navigation system to the 3-dimensional Slicer software package, which used this position to seed the WM tracts around the tool tip location, rendering a geometric visualization of these tracts on the preoperative images previously loaded onto the navigation system. The clinical feasibility of this approach was evaluated in 5 cases of lesion resection. In addition, system performance was evaluated by measuring the latency between surgical tool tracking and visualization of the seeded WM tracts. RESULTS: Lesion resection was performed successfully in all 5 patients. The seeded WM tracts close to the lesion and other critical structures, as defined by the functional and structural images, were interactively visualized during the intervention to determine their spatial relationships relative to the lesion and critical cortical areas. Latency between tracking and visualization of tracts was less than a second for a fiducial radius size of 4 to 5 mm. CONCLUSION: Interactive tractography can provide an intuitive way to inspect critical WM tracts in the vicinity of the surgical region, allowing the surgeon to have increased intraoperative WM information to execute the planned surgical resection.

Full textAbstract:
The achievements of multicolor photoluminescent (PL)-emissive carbon dots (CDs), particularly red to near infrared (NIR), are critical for their applications in optoelectronic devices and bioimaging, but it still faces great challenges to date. In this study, PL emission red-shifts were observed when tartaric acid (TA) was added into m-phenylenediamine (mPD) or o-phenylenediamine (oPD) solutions as carbon sources to prepare CDs, i.e., from blue to green for mPD and from yellow-green to red for oPD. Morphology and structure analyses revealed that the increased surface oxidation and carboxylation were responsible for the red-shifts of emission, indicating that TA played a key role in tuning the surface state of CDs. These factors could be employed as effective strategies to adjust PL emissions of CDs. Consequently, multicolor PL CDs (i.e., blue-, green-, yellow-green- and red-emissive CDs) can be facilely prepared using mPD and oPD in the absence and presence of TA. Particularly, the obtained red-emissive CDs showed a high PL quantum yield up to 22.0% and an emission covering red to NIR regions, demonstrating great potentials in optoelectronic devices and bioimaging. Moreover, multicolor phosphors were further prepared by mixing corresponding CDs with polyvinylpyrrolidone (PVP), among which the blue, green, and red ones could serve as three primary color phosphors for fabricating multicolor and white light-emitting diodes (LEDs). The white LED was measured to show a Commission Internationale de L’Eclairage (CIE) 1931 chromaticity coordinate of (0.34, 0.32), a high color rendering index (CRI) of 89, and a correlated color temperature (CCT) of 5850 K, representing one of the best performances of white LEDs based on CDs.

Full textAbstract:
<p><strong>Abstract.</strong> Flow maps, where counts of people or things are shown travelling between origin-destination pairs with paths or arrows, are difficult to draw well, mostly because they rapidly get cluttered as more and more paths are added. Researchers in cartographic and information visualization fields have sought to mitigate these problems in various ways, including cluster detection and edge bundling (Buchin, Speckmann, & Verbeek, 2011; Guo, 2009), force-directed path placement (Holten & van Wijk, 2009; Jenny et al., 2017), use of network topological space instead of planimetric space (Xiao & Chun, 2009), interactive spatial filtering of flows (Vrotsou, Fuchs, Andrienko, & Andrienko, 2017), and by changing the drawing medium to accommodate flows that arc through 3D space (Raposo, 2017; Yang et al., 2019; Zhang, Zhang, Li, & Li, 2018). Other geovisualization techniques recently developed involve and use of matrixes or grids to store and visualize flows; Wood, Dykes, & Slingsby (2010) use spatial tessellation and a set of small multiples of the same tessellation representing origin and destination spaces, respectively, creating a sort of travel heat map when tiles are colored as a choropleth. A comparable approach is taken by Yang et al. (2017) in a system that combines an abstract matrix of flow records with inflow and outflow maps.</p><p>This early-stage project builds on previous matrix-based flow visualization methods while leveraging the power of Discrete Global Grid Systems (DGGS), which present a naturally Earth-oriented hierarchical tessellation upon which a matrix of origins and destinations can be stored and visualized. DGGS (Sahr, White, & Kimerling, 2003; Raposo, Robinson, & Brown, in press) partition the round Earth into nested tiles in a manner similar to quad-trees, and have the desirable properties of covering the whole spherical globe in equal-area (or near equal-area) tiles, and of being hierarchical to an arbitrary number of levels. The hierarchical quality allows flows in a DGGS to be naturally bundled by origin and destination points as a function of grid size; greater or lesser detail (i.e., more or less bundling) in the overall pattern of flows is effected by descending or ascending DGGS levels. As DGGS are becoming increasingly popular for geospatial data computation and collection in movement analysis (Brodsky, 2018), the present work provides a natural bridge to the visualization of such data when it pertains to movement phenomena.</p><p>The present research will develop a suite of flow visualization techniques upon an existing open-source DGGS rendering platform (Raposo, Robinson, & Brown, in press): 1) grid facet coloring in a choropleth scheme to indicate magnitudes of flow into or out of a particular facet; 2) vertical-space cubic spline flow arcs, and 3) tabular representation of the flow data. All three visualization techniques will function across multiple spatial resolutions, corresponding to each of the hierarchical levels of our chosen DGGS, so that users can interact both with each of the three visualizations of the data as well as the spatial granularity to which the data are displayed. All views will be interactive and linked.</p><p>We use Dutton’s (1999) quaternary triangular mesh (QTM), being a DGGS based on recursively subdividing the faces of an octahedron over the globe (Figure 1). Our method begins by finding, at many nested QTM levels, the facets of the QTM with which each origin and destination point intersects; in practice, we use up to 16 levels, as the triangles at that level in the QTM are small enough to address typical individual buildings. Importantly, point-in-polygon intersection is calculated geodetically, and not in 2D projected space, since failing to do this can cause topological errors (Raposo, Robinson, Brown, in press). At each QTM facet and at each level, we build two lists: one of all the other facets at that level that contain an origin point for a flow that arrives at this facet, and another of those that contain a destination point for flows originating in this facet. These lists are stored to each facet as polygon attributes. A flow path curving through vertical space via a cubic spline is also derived for each origin-destination pair and stored as a renderable 3D solid.</p><p>The QTM is then plotted in our software on a virtual globe using NASA’s World Wind application programming interface. As users select any one QTM facet, its attributes are read to find all the other facets either contributing or receiving flows to or from the selected facet; these are then colored according to a choropleth scheme to visualize magnitudes of flow (Figure 2). Coloration is controlled for various descriptive statistics on the flows (e.g., total, mean, maximum, etc.). Linear paths curving up and around the globe (Figure 3) will also be available to be toggled on or off, giving users multiple redundant symbolizations of travel paths.</p>

Background: India, a developing country, faces many challenges in rendering health needs to its countrymen. The influence of culture is seen in every discipline of health and medical practices, and dentistry is no exception. This study was performed to investigate the existence of myths and taboos in dentistry, to assess the variation of these myths across various demographic aspects and socio-economic status, to co-relate the existence of myths with the oral health of the subject and to impart education to the people regarding abolishing the myth as that will be a hindrance towards a healthy life in patients. Methods: The study had a cross-sectional design, used a structured questionnaire and was conducted to assess the existence of dental myths and taboos and to determine its correlation with the OHIS index of the patients. Statistical analysis software SPSS V 16.0 was used. Descriptive & inferential statistical analysis was performed on categorical and continuous data. Chi-square, independent sample T tests and ANOVA test were used to compare the distribution of caries and OHI-S between different groups. P value less than 0.05 (p<0.05) was considered to be significant. Socioeconomic status was also calculated.Results: In the present study it was found that the there was almost an equal distribution of prevalence of myths in the educated as well as uneducated patients .Also the ratio of existence of myths was found higher in females as compared to males.Conclusions: Existence of myths and taboos regarding dental health has started decreasing among the urban population due to the widespread of awareness regarding dentistry.But still there is prevalence of some myths in the patients having primary education as compared to patients having secondary and tertiary education. If community is educated about proper prevention and cure, the myths relating dental concepts will vanish from the society and over all dental health status of the community will improve.

Relevance. The available unique experience of elimination of medical and sanitary consequences of emergency situations of natural, technogenic and social nature proves that the effectiveness of rendering medical care within or on the border of emergency area depends on timely arrival and actions of non-staff healthcare professionals of the All-Russian service for disaster medicine – crews for specialized medical care, physician-and-nurse crews. Directly during training and practical activities non-staff healthcare professionals face problematic issues affecting their readiness and quick response.Intention. To define the most significant problematic issues influencing work of non-staff healthcare professionals of the Service for disaster medicine of the Ministry of Defense of the Russian Federation on elimination of medical and sanitary consequences of emergency situations.Methodology. Content analysis of the facts and trends in the documents regulating activities of non-staff healthcare professionals of emergency formations was performed. Non-staff physicians were surveyed on problematic issues of training, practical activities and professional competence and importance of these issues ranked: “not important” – 1, “important” – 2, “very important” – 3 with assigning respective points.Results and Discussion. In the military-medical organizations of the central subordination, including the Kirov Military Medical Academy, emergency formations of Service for disaster medicine of the Ministry of Defense of the Russian Federation exist to strengthen (special-purpose) medical groups and medical institutions responsible for admitting casualties from emergency areas. An “average portrait” of a non-staff healthcare professional was as follows: male surgeon of 38.7±1.1 after a clinical internship, with an academic degree and experience in subject domain of 13.4 years. He has served (worked) at the Kirov Military Medical Academy and carried out functional duties on a constant basis, with experience more than two years as a part of physician-nurse or specialized medical care (thoracoabdominal) crew, with sufficient experience in elimination of medical and sanitary consequences of emergencies. At the same time during training and practical activities he faces a number of issues, such as labor relations and quality assessment of performance during elimination of medical and sanitary consequences of emergency situations, unsatisfactory resource and organizational support and also low readiness of all the non-staff members of the crew.Conclusion. Besides problematic issues of labor relations in emergency formations, the factors influencing training, performance and professional competence of non-staff healthcare professionals were defined, i.e. special equipment for medical evacuation (sanitary aviation); unsatisfactory facilities intended for elimination of medical and sanitary consequences of emergencies; medical equipment in emergency areas. As a result of the analysis, all the problematic issues were limited to 3 fundamental internal (hidden) factors influencing training, performance and professional competence of healthcare professionals at the Kirov Military Medical Academy: “Basic resources” (22.05%), “Shortcomings in daily activities” (11.9%), “Readiness for actions” (10.4%). To minimize the specified problematic issues, various (alternative) options are suggested.

When modeling contact between a solid body represented with beam or shell theory and a domain discretized with solid finite elements, the contact model faces the typical challenges of enforcing geometric compatibility and the transfer of a complete pressure field along the contact interface, with the added complications stemming from the different underlying mathematical formulations and finite element discretizations in the connecting domains. Resultant-based beam and shell theories do not provide direct estimates of surface tractions, therefore rendering the issue of pressure transfer on beam–solid and shell–solid interfaces more problematic. In the absence of specialized contact formulations for solid–beam and solid–shell interfaces, contact models have relied almost exclusively on the Node-To-Surface (NTS) geometric compatibility approach. This formulation suffers from well-known drawbacks, including instability, surface locking and incomplete pressure fields on the interface. The NTS approach, however, remains the method most readily applicable to contact with beam or shell elements among the vast variety of available methods for computational contact modeling using finite elements. The goal of this paper is to bridge the gap in the literature on coupling domains with beam and solid finite element discretizations. We propose an interface formulation for beam–solid interfaces that ensures the transfer of a complete pressure field while enforcing geometric compatibility using standard NTS constraints. The formulation uses a stabilization approach, based on a special form of the Discontinuous Galerkin method, to enforce weak continuity between the stress fields on the solid side of the interface, and the moment and shear resultants in the contacting beam. We show that the proposed formulation is a robust approach for satisfying compatibility constraints while ensuring the transfer of a complete pressure field on beam–solid finite element interfaces that can be used with bilinear and quadratic interpolations in the solid, and Euler or Timoshenko formulations for the beam.

Full textAbstract:
Based on the facts in medical images that there are many empty voxels and the near scene is more sensitive to human vision, our accelerating rendering algorithm divides the rendering process into near scene and far scene parts. An accelerated ray-casting method is adapted for rendering the near scene and a fast splatting method is adapted for rendering the far scene. The inherent coherence existed in adjacent frames is used to accelerate the navigation speed. A part of far scene of the next frame may be simply rendered by view transforming the part of far scene of the current frame.

Full textAbstract:
Purpose – To review and analyze the implications for rendering opinions in connection with the sale of securities in the wake of the US Supreme Court’s decision in Omnicare, Inc. et al. v. Laborers District Council Constr. Ind. Pension Fund, et al. Design/methodology/approach – Analyzes the Omnicare holding and dissent in light of past practices and decisions and discusses how the case changes the risks of liability for rendering opinions in registration statements, and by necessary implication in other contexts where the securities laws proscribe either the statement of untrue “facts” or, by omissions, the making of misleading “statements.” Findings – Omnicare opens issuers and securities professionals to liability for rendering opinions that are not reasonably based in facts and rationality. Because the measure of such reasonableness depends on the reasonable investor, makers of opinions will need to take more matters into consideration in rendering opinions than they might have previously, when the only test of an opinion was whether it was genuinely believed by its maker. This creates a number of unresolved issues, but it also suggests that prudence will dictate more detailed disclosure and documentation of the bases of opinions than has been thought necessary until now. Originality/value – Practical guidance from experienced securities and financial services lawyers.

Full textAbstract:
The current report deliberates the challenges encountered by the various sectors of healthcare workers while executing their services. The study is confined to Indian state of rural Maharashtra precisely involving the small town Masur and Karad city of Satara district. Here, we tried to better comprehend the daily problems confronted by the health workers while rendering their services especially in rural area. For the purpose we met with the various health workers including physician, nurse, blood bank founder, and the pharmacist. All of them highlighted the problems they dealt with while rendering their daily services and also emphasized on implications of covid 19 on their duties. Niti Ayog has already warned center regarding the possibility of third wave of covid 19 by the end of September 2021 with 4-5 lakhs daily cases. Indeed, this is alarming and may curtail current health care system. Taking into account the daily challenges confronted by the healthcare personals and possible damage by covid 19, the current heathcare system especially in rural Maharashtra need a substantial boost.

Full textAbstract:
The most important action of the criminal court is presentation of evidence and it may be undertaken during the whole criminal procedure. This was the main reason why this court action was placed in the part of the new Criminal Procedural Law of Montenegro related to general issues, instead of placing it in the part with investigation like in earlier solutions. The reasons for those changes as well as for repeal of some previous solutions/articles of the Criminal Procedural Law, in accordance with which some illegally presented evidences could have been used in the criminal procedure even for rendering the final court decision, were based on the fact that it was necessary to implement some solutions from modern criminal procedural law of the European countries as well as to implement relevant solutions from European Declaration on Human Rights, in order to improve human rights and to reach European human right standards. Therefore, all illegal evidence cannot be used anymore in rendering court decisions, have to be excluded from the case file and to be used never again under any circumstances. This paper pays special attention to the statement of the accused and technical records (audio-video) of criminal facts, which are the two most important sources of illegal evidence.
