Abstract:

Pulmonary arteriovenous malformations (PAVMs) are abnormal direct vascular communications between pulmonary arteries and veins which create high-flow right-to-left shunts. They are most frequently congenital, usually in the setting of hereditary hemorrhagic telangiectasia (HHT). PAVMs may be asymptomatic or present with a wide variety of clinical manifestations such as dyspnea, hypoxemia, or chest pain. Even when asymptomatic, presence of PAVMs increases patients’ risk of serious, potentially preventable complications including stroke or brain abscess. Transcatheter embolotherapy is considered the gold standard for treatment of PAVMs. Though previous guidelines have been published regarding the management of PAVMs, several aspects of PAVM screening and management remain debated among the experts, suggesting the need for thorough reexamination of the current literature. The authors of this review present an updated approach to the diagnostic workup and management of PAVMs, with an emphasis on areas of controversy, based on the latest literature and our institutional experience.

Abstract:

SummaryIn nowadays life science projects, sharing data and data interpretation is becoming increasingly important. This considerably calls for novel information technology approaches, which enable the integration of expert knowledge from different disciplines in combination with advanced data analysis facilities in a collaborative manner. Since the recent development of web technologies offers scientific communities new ways for cooperation and communication, we propose a fully web-based software approach for the collaborative analysis of bioimage data and demonstrate the applicability of Web2.0 techniques to ion mobility spectrometry image data. Our approach allows collaborating experts to easily share, explore and discuss complex image data without any installation of software packages. Scientists only need a username and a password to get access to our system and can directly start exploring and analyzing their data.

Abstract:

Drawing from a framework highlighting how family influence is reflected in organizational identity, we present archival and content analytic adaptations for three key factors signifying alignment between family and organizational identities: family visibility, transgenerational sustainability, and family self-enhancement. We validate these measures using archival data sources, “About Us” pages, and shareholder letters from S&P 500 firms. Random coefficients modeling indicates our measures are largely shaped by temporal and firm, followed by industry, differences. Our work paves the way for further investigation exploring the relationships between family involvement and organizational identity while simultaneously addressing lingering methodological challenges in family business research.

The impetus of this paper is to broaden the structure of linguistic soft set (LSS) to a new domain namely sigmoid valued fuzzy soft set (SVFSS). Some operating laws on SVFSS are also provided. Using the complement concept on SVFSS we define maximum rejection. This maximum rejection paves a way for defining a new similarity measure on SVFSS termed as maximum likely ratio (MLR). A new MCGDM algorithm for SVFSS is proposed using MLR. An illustrative example of haze equipment problem on sigmoid valued fuzzy soft set setting is also given. A comparative analysis of our approach with the existing approaches are also presented to justify our work.

Abstract:

Pulmonary arteriovenous malformations (PAVMs) are abnormal connections between pulmonary artery and vein through a thin-walled aneurysmal sac, leading to a right-to-left shunt. These are commonly associated with hereditary hemorrhagic telangiectasia, and treatment guidelines have been set on how to approach their management. Incorrect proximal placement of an embolization device can lead to delayed recruitment of systemic collaterals leading to presentation with hemoptysis. We are presenting a case of a 17-year-old male with treated PAVMs and with fresh hemoptysis. In this case report, we attempt to explain the management of such a complication and follow the principles of arteriovenous malformation embolization on the left side.

Full text

Abstract:

Autogenous arteriovenous access is the preferred access for hemodialysis patients with end-stage renal disease but is not feasible in a significant number of patients. The creation of a prosthetic arteriovenous access (PAVA) for hemodialysis using expanded polytetrafluoroethylene is technically simple and the short-term results are usually good, but the PAVA's 1-year patency rate is low (less than 60% in many centers). We have developed an integrated approach for the creation and maintenance of PAVAs, under the direction of a dedicated vascular access surgeon, involving preoperative imaging, anesthetic and surgical techniques, and a postoperative graft surveillance program, to improve patency rates. The design used was a prospective nonrandomized study. Between January 1, 1999, and December 31, 2001, 158 PAVAs were created (36.8% of the 419 fistulae created during this period). High-resolution duplex ultrasonography was added to careful clinical assessment in planning and follow-up of the dialysis access. The preferred method of PAVA creation was the forearm loop using tapered 4 to 7 mm stretch expanded polytetrafluoroethylene. After surgery, patients entered a program of close follow-up and regular graft surveillance and maintenance. Prophylactic surgical revisions and endovascular interventions were performed routinely according to ultrasonography findings to prevent thrombosis. Thrombolysis and thrombectomy were performed without delay when the PAVA thrombosed, minimizing the use of central venous access and salvaging the central veins. No patients were excluded from the study. One-, 2-, and 3-year assisted primary patency rates (including patients without occlusion but who were judged to require prophylactic revision) were 65%, 54.1%, and 48.8%, respectively. With surveillance-directed surgical revisions and endovascular treatment before or after occlusion, the 1-, 2-, and 3-year secondary patency rates (functional patency) were 91.4%, 84.3%, and 78.5%. Of the 158 grafts, 110 never occluded during the study period. There were 155 interventions in 74 PAVAs: 30 surgical revisions, 63 prophylactic endovascular procedures, and 52 instances of thrombolytic therapy combined with percutaneous transluminal angioplasty. The use of prosthetic arteriovenous access for hemodialysis, when autogenous arteriovenous access is not feasible, can still be associated with excellent long-term patency, in spite of previously published poor results, as long as good planning, close follow-up, and aggressive intervention (when indicated) are carried out.

Full text

Abstract:

The compatibility of free boronic acid building blocks in multicomponent reactions to readily create large libraries of diverse and complex small molecules was investigated. Traditionally, boronic acid synthesis is sequential, synthetically demanding, and time-consuming, which leads to high target synthesis times and low coverage of the boronic acid chemical space. We have performed the synthesis of large libraries of boronic acid derivatives based on multiple chemistries and building blocks using acoustic dispensing technology. The synthesis was performed on a nanomole scale with high synthesis success rates. The discovery of a protease inhibitor underscores the usefulness of the approach. Our acoustic dispensing–enabled chemistry paves the way to highly accelerated synthesis and miniaturized reaction scouting, allowing access to unprecedented boronic acid libraries.

Abstract:

Purpose The paper aims to use a switching technique which allows to couple a nonlocal bond-based Peridynamic approach to the Meshless Local Exponential Basis Functions (MLEBF) method, based on classical continuum mechanics, to solve planar problems. Design/methodology/approach The coupling has been achieved in a completely meshless scheme. The domain is divided in three zones: one in which only Peridynamics is applied, one in which only the meshless method is applied and a transition zone where a gradual transition between the two approaches takes place. Findings The new coupling technique generates overall grids that are not affected by ghost forces. Moreover, the use of the meshless approach can be limited to a narrow boundary region of the domain, and in this way, it can be used to remove the “surface effect” from the Peridynamic solution applied to all internal points. Originality/value The current study paves the road for future studies on dynamic and static crack propagation problems.

Full text

Abstract:

This article describes a new approach to the generation of referring expressions. We propose to formalize a scene (consisting of a set of objects with various properties and relations) as a labeled directed graph and describe content selection (which properties to include in a referring expression) as a subgraph construction problem. Cost functions are used to guide the search process and to give preference to some solutions over others. The current approach has four main advantages: (1) Graph structures have been studied extensively, and by moving to a graph perspective we get direct access to the many theories and algorithms for dealing with graphs; (2) many existing generation algorithms can be reformulated in terms of graphs, and this enhances comparison and integration of the various approaches; (3) the graph perspective allows us to solve a number of problems that have plagued earlier algorithms for the generation of referring expressions; and (4) the combined use of graphs and cost functions paves the way for an integration of rule-based generation techniques with more recent stochastic approaches.

Full text

Abstract:

Several approaches have been proposed for computing term information content (IC) and semantic similarity scores within the gene ontology (GO) directed acyclic graph (DAG). These approaches contributed to improving protein analyses at the functional level. Considering the recent proliferation of these approaches, a unified theory in a well-defined mathematical framework is necessary in order to provide a theoretical basis for validating these approaches. We review the existing IC-based ontological similarity approaches developed in the context of biomedical and bioinformatics fields to propose a general framework and unified description of all these measures. We have conducted an experimental evaluation to assess the impact of IC approaches, different normalization models, and correction factors on the performance of a functional similarity metric. Results reveal that considering only parents or only children of terms when assessing information content or semantic similarity scores negatively impacts the approach under consideration. This study produces a unified framework for current and future GO semantic similarity measures and provides theoretical basics for comparing different approaches. The experimental evaluation of different approaches based on different term information content models paves the way towards a solution to the issue of scoring a term’s specificity in the GO DAG.

Abstract:

Purpose – In the context of social media marketing, so called viral stealth videos (VSVs) often attract as much or even more attention than videos that directly advertise products (product advertising video (PAV)). However, beyond this, the product or brand-related impact of such videos is not so clear. In this context, the purpose of this paper is to investigate brand perception of PAVs and VSVs in YouTube. Design/methodology/approach – The research design is based on an examination of comments of six VSVs and six PAVs on YouTube. Therefore, the content of 1,080 posts was analyzed to capture the topic, the attitude toward the video and the pragmatic intent of posts. Findings – Results indicate that there are strong differences with regard to users ' perception of the two analyzed video type segments. The content of VSVs is clearly recognized as positive more often than the content of PAVs. In contrast, only PAVs evoke substantial brand awareness but receive rather mixed results with regards to brand assessment. Research limitations/implications – As a whole, the study is widely descriptive and of explorative value. Nevertheless, the research design can be estimated as a first step to measure the brand-related impact of online videos. Ideally, the data generated in the investigation should be combined with traffic and conversion data of the brands’ websites to get an encompassing picture of the marketing related impact of the investigated online videos. Practical implications – Seen from a marketers’ perspective, one can recommend PAVs over VSVs as there are hardly any brand-related impacts of VSVs visible in online communication. PAVs are perceived less positively but they are able to evoke brand awareness at least. Originality/value – According to the authors’ knowledge this investigation is one of only a few studies that analyzes real online communication in the context of video-based online marketing.

Abstract:

One of the problems of applying semiotic techniques to theatre work has been a vocabulary which too often mystifies rather than clarifies the theatre experience for the non-specialist student. Patrice Pavis, in his work with students at the University of Paris III, has evolved a questionnaire about theatre performance which, while not in itself utilizing semiotic terminology, attempts to direct the respondents' attention to all the aspects of theatrical signification upon which it touches. In the following article, Patrice Pavis, whose major study of theatrical terminology, entitled Dictionnaire du Théâtre, was published by Editions Sociales in 1980, outlines the purpose of the questionnaire, and provides explanatory notes to the individual questions, outlining an approach on which many involved in theatre teaching may wish to comment and build.

Full text

Abstract:

A general approach is proposed for defining the macroscopic free-energy function of a saturated porous medium subjected to finite deformations, under isothermal conditions, in the case of compressible fluid and solid constituents. Reference is made to an elementary volume treated as an ‘open system’, moving with the solid skeleton. The strain-like variables are characterized by a suitable strain measure and the variation of fluid-mass content. Although the free energy is obtained by assembling the contributions of the single constituents, the resulting free energy is not the simple sum of the free energies of the single constituents. It is shown that the simplified approaches previously proposed in the literature are recovered as particular cases of the more general framework proposed in the present article and, in addition, new simplified constitutive frameworks are investigated. The proposed approach paves the way to the consistent hyperelastic–plastic and thermo-elastic modelling of saturated porous media with compressible fluid and solid constituents.

Abstract:

Organizations need to focus on many parameters to reach their goals such as personnel satisfaction at the top level, profit maximization, increasing system efficiency and minimizing costs. By carefully examining the significant effect of personnel scheduling on the production of goods and services, achieving a fair distribution of work among the employees paves the way for higher motivation and performance of the employees, particularly, in production and service industries. In this paper, a systematic literature review (SLR) approach is used to demonstrate the necessity of scheduling studies in order to overcome the deficiencies in auxiliary activity groups. It sheds light on a new and very important areas such as examining the model structures of sector differences, and guiding researchers. New trends and approaches are presented for the personnel scheduling problems. Different classification perspectives are displayed.

An alternative triangulation experiment is sketched, demonstrating how the removal of such training sessions paves the way toward solving the distinguishability problem.

Abstract:

Purpose This paper reports a study that compares two different team-building approaches. The first one is the traditional top-down management approach. The second one is a hybrid bottom-up approach based on the consensus model. The aim of this paper is to determine which of the two approaches is the most effective across a number of performance measurements. Design/methodology/approach A case study is presented using data collected and analysed from a small family-owned vehicle maintenance firm. A mixed methods approach to data collection is utilized, including participant observation, focus groups, survey questionnaires and organizational performance reports. A convenience sample of eight routine maintenance jobs was selected for team performance comparison purposes. The measures used for comparing the two team approaches were lead time, customer satisfaction ratings and employees’ satisfaction ratings. Findings The teams assembled using the consensus approach performed better than those selected using the traditional top-down approach across all three performance measures, i.e. the jobs were completed faster and both customers and employees were more satisfied. Research limitations/implications This is an exploratory case study limited to one small family-owned business and, as such, findings may not be generalizable. Practical implications As an alternative to manager selected work teams, managers should involve and empower employees to select their own teams. This has the potential to offer benefits for both customers and employees of faster delivery times and increase satisfaction, as well as increase productivity for the firm. Originality/value This is the first field study to compare the performance of a hybrid, bottom-up approach to team building with the performance of a more traditional management, top-down approach to team building. It paves the way for a wider study to be conducted in the future to test the findings’ generalizability.

Abstract:

Despite the fact that imbalance between case and control groups is prevalent in genome-wide association studies (GWAS), it is often overlooked. This imbalance is getting more significant and urgent as the rapid growth of biobanks and electronic health records have enabled the collection of thousands of phenotypes from large cohorts, in particular for diseases with low prevalence. The unbalanced binary traits pose serious challenges to traditional statistical methods in terms of both genomic selection and disease prediction. For example, the well-established linear mixed models (LMM) yield inflated type I error rates in the presence of unbalanced case-control ratios. In this article, we review multiple statistical approaches that have been developed to overcome the inaccuracy caused by the unbalanced case-control ratio, with the advantages and limitations of each approach commented. In addition, we also explore the potential for applying several powerful and popular state-of-the-art machine-learning approaches, which have not been applied to the GWAS field yet. This review paves the way for better analysis and understanding of the unbalanced case-control disease data in GWAS.

Abstract:

The digitization of Cultural Heritage paves the way for new approaches to surveying and restitution of historical sites. With a view to the management of integrated programs of documentation and conservation, the research is now focusing on the creation of information systems where to link the digital representation of a building to semantic knowledge. With reference to the emblematic case study of the Calci Charterhouse, also known as Pisa Charterhouse, this contribution illustrates an approach to be followed in the transition from 3D survey information, derived from laser scanner and photogrammetric techniques, to the creation of semantically enriched 3D models. The proposed approach is based on the recognition -segmentation and classification- of elements on the original raw point cloud, and on the manual mapping of NURBS elements on it. For this shape recognition process, reference to architectural treatises and vocabularies of classical architecture is a key step. The created building components are finally imported in a H-BIM environment, where they are enriched with semantic information related to historical knowledge, documentary sources and restoration activities.

Abstract:

Abstract The article looks into the case involving Fabiano Antoniani, who, following a major road accident, was left tetraplegic. Marco Cappato drove him to a Swiss clinic where Mr. Antoniani took his own life by self-administration of lethal pentobarbital sodium. Cappato was put on trial, but the Italian Constitutional Court urged the Parliament to decriminalise assisted suicide in extremely serious cases. From a comparison with other European countries, approaches range from restrictive (banning both active euthanasia and assisted suicide), to entirely permissive. An intermediate approach only entails a ban on active euthanasia. It would be desirable to uniformise the diverse national statutes on a European level, which would make it possible for everyone to receive assistance towards ending their suffering, with limitations to incurable cases to be medically verified, and at the end of a path designed to ensure that patient freedom of choice is upheld at all time.

Full text

Abstract:

Extracting structural information from sequence co-variation has become a common computational biology practice in the recent years, mainly due to the availability of large sequence alignments of protein families. However, identifying features that are specific to sub-classes and not shared by all members of the family using sequence-based approaches has remained an elusive problem. We here present a coevolutionary-based method to differentially analyze subfamily specific structural features by a continuous sequence reweighting (SR) approach. We introduce the underlying principles and test its predictive capabilities on the Response Regulator family, whose subfamilies have been previously shown to display distinct, specific homo-dimerization patterns. Our results show that this reweighting scheme is effective in assigning structural features known a priori to subfamilies, even when sequence data is relatively scarce. Furthermore, sequence reweighting allows assessing if individual structural contacts pertain to specific subfamilies and it thus paves the way for the identification specificity-determining contacts from sequence variation data.

Abstract:This essay presents a cross-sectoral analysis of innovation in some types of services, namely air traffic control, retail banking, and health care. The provision of such services is organized in network structures whose development relies on competences and activities that cut across traditional sectoral and industrial boundaries. The conceptual background provided by the recent synthesis approach explains these features by elaborating a new concept of system of innovation. In so doing, this approach paves the way for new understanding of innovation in services as the endogenous outcome of knowledge growth within and across technologies, organizations, and institutions.

Abstract:

Optical compensation is studied for suppressing polarization nonreciprocity (PN) induced errors in interferometric fiber-optic gyroscopes (IFOG). In convention IFOGs, a polarizer is necessarily used, and only one polarization is used for interference in order to achieve low PN error. Differently, we propose a new approach for using two polarizations simultaneously in the IFOG. PN error can be effectively suppressing by optical compensation between the two detected signals. Both simulation and experiment are presented, which shows that PN errors are effectively reduced by optical compensation. This new approach paves the way for low drift IFOGs with no polarizer.

We also present a generally applicable approach step-wise dehydration process of MnC2O4·3H2O based on molecular dynamic simulations. Also, first principles calculations of NMR parameters along with the magnetic susceptibility were performed to reveal new insights into a quite exotic behavior which hampered the experimental way once by the domination of large paramagnetic shift of the d-electrons. The proposed approach paves the way for setting possible widenings by the implementation of computational strategies for such type of systems.

Abstract:

Plant growth is a self-organized process incorporating distributed sensing, internal communication and morphology dynamics. We develop a distributed mechatronic system that autonomously interacts with natural climbing plants, steering their behaviours to grow user-defined shapes and patterns. Investigating this bio-hybrid system paves the way towards the development of living adaptive structures and grown building components. In this new application domain, challenges include sensing, actuation and the combination of engineering methods and natural plants in the experimental set-up. By triggering behavioural responses in the plants through light spectra stimuli, we use static mechatronic nodes to grow climbing plants in a user-defined pattern at a two-dimensional plane. The experiments show successful growth over periods up to eight weeks. Results of the stimuli-guided experiments are substantially different from the control experiments. Key limitations are the number of repetitions performed and the scale of the systems tested. Recommended future research would investigate the use of similar bio-hybrids to connect construction elements and grow shapes of larger size.

Abstract:

Water constitutes one of the basic necessities of life. Around 71% of the Earth is covered by water, however, not all of it is readily available as fresh water for daily consumption. Fresh water scarcity is a chronic issue which poses a threat to all living things on Earth. Seawater, as a natural resource abundantly available all around the world, is a potential water source to fulfil the increasing water demand. Climate-independent seawater desalination has been touted as a crucial alternative to provide fresh water. While the membrane-based desalination process continues to dominate the global desalination market, the currently employed membrane fabrication materials and processes inevitably bring adverse impacts to the environment. This review aims to elucidate and provide a comprehensive outlook of the recent efforts based on greener approaches used for desalination membrane fabrication, which paves the way towards achieving sustainable and eco-friendly processes. Membrane fabrication using green chemistry effectively minimizes the generation of hazardous compounds during membrane preparation. The future trends and recommendations which could potentially be beneficial for researchers in this field are also highlighted.

Abstract:

A facile solution treatment strategy for controlling the microstructure of conjugated polymers using a non-solvent vapor is introduced. The content of well-ordered poly(3-hexylthiophene) (P3HT) aggregates in solution was precisely controlled by varying the non-solvent vapor exposure time. P3HT chains were self-assembled upon exposure to the non-solvent vapor to minimize the unfavorable interactions with the non-solvent molecules. The effect of solvent vapor on the molecular ordering and morphologies of P3HT films was investigated by UV-Vis spectroscopy, atomic force microscopy, and polarized optical microscopy. These studies reveal that the self-assembled P3HT aggregates have well-ordered nanofibrillar structures formed via [Formula: see text]–[Formula: see text] stacking. This strategy paves the way toward fabricating well-ordered polymeric structures, especially in the field of opto-electronic applications including FETs, LEDs, and lasers, where proper alignment or molecular assembly is in great demand.

Abstract:

AbstractMolecular-level control of charge transfer (CT) is essential for both, organic electronics and solar-energy conversion, as well as for a wide range of biological processes. This article provides an overview of the utility of local electric fields originating from molecular dipoles for directing CT processes. Systems with ordered dipoles, i.e. molecular electrets, are the centerpiece of the discussion. The conceptual evolution from biomimicry to biomimesis, and then to biological inspiration, paves the roads leading from testing the understanding of how natural living systems function to implementing these lessons into optimal paradigms for specific applications. This progression of the evolving structure-function relationships allows for the development of bioinspired electrets composed of non-native aromatic amino acids. A set of such non-native residues that are electron-rich can be viewed as a synthetic proteome for hole-transfer electrets. Detailed considerations of the electronic structure of an individual residue prove of key importance for designating the points for optimal injection of holes (i.e. extraction of electrons) in electret oligomers. This multifaceted bioinspired approach for the design of CT molecular systems provides unexplored paradigms for electronic and energy science and engineering.

Full text

Abstract:

Endothelin is a chemical mediator that helps in maintaining balance within the blood-brain barrier by regulating the levels of toxicants and molecules which pass through the brain, suggesting that a rise in its production determines Alzheimer’s disease. The inequity in the amyloid β occurs due to a problem in its clearance from the brain initiating the production of reactive oxygen species and superoxide that activates a cascade wherein the release of inflammatory mediators and various enzymes like endothelin-converting enzymes take place. Furthermore, the cascade increases the levels of endothelin in the brain from endothelial cells. Endothelin levels are upregulated, which can be regulated by modulating the action of endothelin-converting enzymes and endothelin receptors. Hence, endothelin paves a pathway in the treatment of Alzheimer’s disease. In this article, we have covered various mechanisms and preclinical studies that support and direct endothelin involvement in the progression of Alzheimer’s disease by using various search tools such as PubMed, Science Direct, and Medline. Conclusive outcome data were extracted that all together defy contrivance pathways, potential drugs, endothelin receptors, and endothelin enzymes in our article giving profound importance to target endothelin for prevention and treatment of Alzheimer’s disease.

Abstract:

The shift from traditional towards more learner-centered approaches to teaching has resulted in the concept of authenticity becoming central to Communicative Language Teaching (CLT). As a relational notion, authenticity has to do with the interaction between learners and input materials in terms of appropriate responses, as opposed to its notion of genuineness as an absolute quality. It paves the way for language to be authenticated through context, as it encourages a use-to-learn rather than a learn-to-use approach. Using authentic materials requires a great deal of attention to be paid to not only the contextualization and authenticity of tasks, but also to the incorporation of genuine texts into task design, which itself has been revolutionized through modern technology. Using the Web as a technological tool has resulted in another version of authenticity, which might be in line with finder authenticity. The main aim of this paper is to argue that the notion of authenticity has come a long way from genuineness to finder authenticity.
