Abstract:
The article attempts to present the advantages of using models in theology in the context of contemporary methodological challenges. The use of renewed hermeneutics can help to reorganize theological thinking to avoid both treating the content of faith in a matter-of-fact manner and reducing it to personal experience. At the same time, fruits of this thinking can be presented in the form of theological models that are simplified representations of a more complex structure. They must not be overly reductive but as holistic, multifaceted, dynamic, and practical as possible. One of the important proposals is the nuptial model developed by Cardinal Angelo Scola. Using this model seems to be inspiring when applied to support, among other things, the correct understanding of sacramentology.

Abstract:
Phenomenon of electrostatic hazards is becoming increasingly prominent with wide application of microelectronic elements. Electrostatic Discharge (ESD) is an extremely complex process, which is not only related to the materials, the object shape and the value of discharging circuit resistance, but also always involved in very complicated process of gas breakdown, so ESD is also a stochastic process which is difficult to repeat. According to the request of standard IEC61000-4-2, simulation circuit of the equivalent Human-Metal Model is established, discharging process is simulated and analyzed, and the influence laws of circuit parameters and distribution parameters for ESD current waveform are obtained. Thus the structure of discharging circuit and element parameters can be determined, test results can be verified to some extent, and the characteristics and influencing factors of ESD process can be known better. Simulation results show that waveform parameters are all within the range of standard errors, which proves that the design of model parameters is correct, the analysis of ESD process is reasonable.

Abstract. Retrievals of the isotopic composition of water vapor from the Aura Tropospheric Emission Spectrometer (TES) have unique value in constraining moist processes in climate models. Accurate comparison between simulated and retrieved values requires that model profiles that would be poorly retrieved are excluded, and that an instrument operator be applied to the remaining profiles. Typically, this is done by sampling model output at satellite measurement points and using the quality flags and averaging kernels from individual retrievals at specific places and times. This approach is not reliable when the modeled meteorological conditions influencing retrieval sensitivity are different from those observed by the instrument at short time scales, which will be the case for free-running climate simulations. In this study, we describe an alternative, "categorical" approach to applying the instrument operator, implemented within the NASA GISS ModelE general circulation model. Retrieval quality and averaging kernel structure are predicted empirically from model conditions, rather than obtained from collocated satellite observations. This approach can be used for arbitrary model configurations, and requires no agreement between satellite-retrieved and modeled meteorology at short time scales. To test this approach, nudged simulations were conducted using both the retrieval-based and categorical operators. Cloud cover, surface temperature and free-tropospheric moisture content were the most important predictors of retrieval quality and averaging kernel structure. There was good agreement between the δD fields after applying the retrieval-based and more detailed categorical operators, with increases of up to 30‰ over the ocean and decreases of up to 40‰ over land relative to the raw model fields. The categorical operator performed better over the ocean than over land, and requires further refinement for use outside of the tropics. After applying the TES operator, ModelE had δD biases of −8‰ over ocean and −34‰ over land compared to TES δD, which were less than the biases using raw modeled δD fields.

Abstract:
SUMMARY This paper introduces a model of language change based on the theory of self-organisation. It is argued that the structure of language is defined by speech as much as speech is determined by grammar and that the emergence of new grammatical options is a process of mutual interaction of these two sides of language. The main principle of this model of language change is that changes can happen only when the system's stability is lost. At this point, called bifurcation point, random fluctuations choose a new stable state. The stability of the system does not depend on fluctuations, but is a function of its control parameter. When this parameter reaches the critical point, one of the fluctuations starts to expand and leads the system into a new steady state. It is argued that external fields can influence the random nature of fluctuations which makes the corresponding changes ('natural' changes) recurrent crosslinguistically. RÉSUMÉ L'article presente un modele des changements langagiers ayant pour base la theorie de l'autoorganisation. Selon ce modele la structure d'une langue n'est pas definie par la grammaire, mais par le discours; les nouvelles structures grammaticales, elles, sont creees par l'interaction de la langue et la grammaire. L'idee principale du modele presente est le fait que les changements peuvent avoir lieu dans la langue seulement au cas où le systeme perd sa stabilite. A un moment donne, appele 'point de bifurcation', des fluctuations fortuites con-duisent le systeme de nouveau a un etat stable. La stabilite du systeme ne depend pas de fluctuations, c'est plutot une fonction d'un parametre de controls Si le parametre arrive a sa valeur critique, Tune des fluctuations croît en importance et conduit le systeme de nouveau a un etat stable. L'article avance l'hypothese que les champs de force peuvent influencer la distribution fortuite des fluctuations qui rend ces changements repetitifs parmi les langues. ZUSAMMENFASSUNG Dieser Artikel stellt ein Sprachwandelmodell vor, das sich auf das Prinzip der Selbstorganisierung gründet. Nach diesem Modell definiert die Rede, nicht die Grammatik, die Struktur der Sprache, und neue grammatische Strukturen bilden sich durch den gegenseitigen EinfluB von Rede und Grammatik. Das Grundprinzip des vorliegenden Modells ist, daB die Anderungen in einer Sprache nur dann vorkommen, wenn das System seine Stabilitat verliert. In diesem Punkt, der als Bifurkationspunkt bezeichnet wird, fiihren die zufalligen Fluktuationen das System in den neuen stabilen Zustand. Die Stabilitat des Systems ist nicht von den Fluktuationen abhangig, sondern ist die Funktion des Kon-trolparameters, die das System leitet. Wenn dieser Parameter seinen kritischen Wert erreicht, nimmt eine von den beiden Fluktuationen zu und fiihrt das System zu einem neuen stabilen Zustand. Der Artikel stellt die Hypothese auf, daB die Kraftefelder auBer dem System die zufallige Distribution der Fluktuationen beeinflussen konnen und dadurch die entsprechenden (sog. natürlichen) Anderungen in den Sprachen der Welt haufig vorkommen.

Valency of Russian verba sentiendi in the light of explicative syntaxThe subject of this article are syntactic (distributional) properties of Russian sentimental verbs (denoting emotions, moods, affects, passions etc.) in a synchronistic view. 319 units of modern Russian language are studied using a theoretical model of explicative syntax, i.e., representation of the propositional structure at the level of grammaticalization of certain argument positions (defined in terms of grammatical classes). The author distinguishes some distributional patterns noted in the source material (explicative schemes), describing them with reference to the meaning of the lexical class as well as to their frequency (functionality).

Abstract:
Automatic crack detection with the least amount of workforce has become a crucial task in the inspection and evaluation of the performances of concrete structure in civil engineering. Recently, although many concrete crack detection models based on convolutional neural networks (CNNs) have been developed, the accuracy of the proposed models varies. Up-to-date, the issue regarding the convolutional neural network architecture with best performance for detecting concrete cracks is still debated in many previous studies. In this paper, we choose three established open-source CNN models (Model1, Model2, and Model3) which have been well-illustrated and verified in previous studies and test them for the purpose of crack detection of concrete structures. The chosen three models are trained using a concrete crack dataset containing 40,000 images those with 227 × 227-pixel in size. The performance of three different convolutional neural network (CNN) models was then evaluated. The comprehensive comparison result indicates that Model2 which used batch normalization is capable of the best performance amongst the three models as selected for concrete cracks detection, with recording the highest classification accuracy and low loss. In a conclusion, we recommend Model2 for a concrete crack detection task.

Abstract:
AbstractUltrastructural observations show that in Saduria entomon (L., 1758) sperm bundles are organized already in the testis, and that a crucial function in this process is played by Sertoli cells, whose protrusions are connected with maturing spermatids. The specific arrangement of maturing spermatids around a Sertoli cell protrusion and their turned-out tails lying centrally in channels reflect the arrangement of spermatozoa in a later bundle. One might assume, therefore, that the pattern along which sperm bundles are organized, which results from their specific structure, is made possible by the way in which the lumen of the testis is penetrated by protrusions of the Sertoli cells. A further role of the Sertoli cells is to produce and secrete matrix components and precursor material for extracellular tubules. Both structures are permanent elements of sperm bundles in isopods. In S. entomon extracellular tubules have a diameter of 80 nm, and their assembling proceeds in close contact with the membrane of a Sertoli cell protrusion. Des observations ultrastructurales montrent que, chez Saduria entomon (L., 1758), les masses spermatiques sont deja organisees dans le testicule et qu'un role crucial dans le processus est joue par les cellules de Sertoli, dont les protrusions sont connectees avec les spermatides en maturation. L'arrangement specifique de ces dernieres autour d'une protrusion de cellule de Sertoli et de leurs queues retournees en position centrale dans les canaux reflete l'arrangement des spermatozoodes dans une masse ulterieure. On peut de ce fait presumer que le modele suivant lequel les masses spermatiques sont organisees, et qui resulte de leur structure specifique, est rendu possible par la facon par laquelle les protrusions des cellules de Sertoli penetrent le testicule. Un autre role des cellules de Sertoli est de produire et de secreter les composants de la matrice et le materiel precurseur pour les tubules extracellulaires. Les deux structures sont des elements permanents des masses spermatiques chez les isopodes. Chez S. entomon, les tubules extracellulaires ont un diametre de 80 nm, et leur assemblage s'effectue en etroit contact avec la membrane d'une protrusion de cellule de Sertoli.

Abstract:
AbstractThe spatial distribution of the abundance indices of the deep-water rose shrimp Parapenaeus longirostris was investigated applying geostatistical techniques on data collected in the central southern Tyrrhenian Sea from bottom trawl surveys carried out in the autumn since 1994. Experimental variograms (auto and cross) were constructed on the variable "abundance index", expressed in kg/km2, and those variogram models best describing the spatial continuity were detected and validated by the jackknife technique. The spatial structure of the "abundance index", exhibiting a similar pattern throughout the surveys, was described by a spherical model and characterized by a spatial continuity at a small scale level in the whole area. The linear geostatistical approach was applied by different kriging techniques and the estimates extended to the spatio-temporal dimension, in this case adopting the co-regionalized models and applying the cokriging technique. This method applied to the spatial dimension (abundance index and depth). Also, linking the spatial and temporal dimension of the abundance indices, measured in two different years, contributed to represent a more accurate picture of the abundance distribution, and allowed the detection of a temporal persistence of the localization of areas with higher abundance, reducing the standard deviation of the estimation error. This information, if coupled with an analysis of the geographical allocation of the fishing effort, could be of importance in stock assessment, allowing some variant application of the composite surplus production models. La distribution spatiale des indices d'abondance de la crevette rose d'eau profonde Parapenaeus longirostris a ete etudiee en appliquant les techniques de la geostatistique aux donnees collectees dans le centre-sud de la mer Tyrrhenienne au cours des campagnes de chalutage demersal realisees pendant l'automne, depuis 1994. Les variogrammes experimentaux (auto et cross) ont ete construits sur la variable "indice d'abondance", exprimee en kg/km2, et les modeles de variogramme decrivants le mieux la continuite spatiale ont ete determines et valides par la technique du "jackknife". La structure spatiale de l'indice d'abondance a presente le meme aspect pour tous les echantillonages; elle a ete decrite au moyen d'un modele spherique et caracterisee par une continuite spatiale a petite echelle dans toute la zone. La geostatistique lineaire a ete appliquee en utilisant differentes techniques du krigeage, et les estimations ont ete etendues a la dimension spatio-temporelle en appliquant les modeles coregionalises et la technique du cokrigeage. Cette methode, appliquee soit dans la dimension spatiale (indice d'abondance et profondeur), soit dans la dimension spatio-temporelle en considerant l'indice d'abondance echantillonne en deux annees differentes, a contribue a representer une image plus precise de la distribution de l'abondance, et a permis de detecter une persistance temporelle de la localisation des aires a plus grande abondance, en reduisant l'ecart type de l'erreur d'estimation. Cette information, avec l'analyse de l'allocation geografique de l'effort de peche, pourrait etre importante dans l'evaluation des stocks, en permettant l'application, avec quelques variantes, des modeles composites de production.

Abstract:
Among the processes of “conquering, developing and appropriating mountains” is occupied by the emergence of mountain topography. In the eighteenth century raised relief, as a terrain model, played one of the most important roles in this process. This was a period when more reliable topographic data began to be collected on the basis of measurements carried out across the Alps. Possibilities of their cartographic representation were limited at the time. A graphic method for presenting orthogonal projection by means of contour curves was not invented until the nineteenth century. Before that three-dimensional terrain models were the only way to correctly represent various levels of landscape. Terrain models were accepted at the time as the best method for presenting mountain landscapes. The first attempt to carry out a comprehensive measurement of the Alps over a vast area of a continuous mountain range and represent it on a low relief was made in 1786 and concerned an area in central Switzerland around Lake Lucerne. At that time Franz Ludwig Pfyffer von Wyher, an officer in French service, became famous for advanced surveying techniques and terrain models, both civilian and military. His famous relief depicts around one-tenth of today’s Switzerland, with two-thirds of the area encompassing the Alps and foot of the Alps. From that moment on other authors began to create their models of Alpine landscape. These reliefs were appreciated by contemporary naturalists, especially those studying the Alps, because they enabled them to view the complex topography of the range, which had been impossible before. They drew attention to a number of natural and geological phenomena, and made it possible to come up with new findings relating to the following questions: At what altitude should the snow line be placed? Where is the boundary of vegetation? Where do coniferous forests begin? Where is the line of glaciers? What is the structure of the mountains? Obviously, they were not sufficient to provide all answers to the above questions, but thanks to a “bird’s eye” perspective they made it possible to place special studies of the various disciplines within a broader context, both with regard to the relevant subject matter and between disciplines.

Abstract:
The main objectives of multi-environmental trials (METs) are to assess cultivar adaptation patterns under different environmental conditions and to investigate genotype by environment (G×E) interactions. Linear mixed models (LMMs) with more complex variance-covariance structures have become recognized and widely used for analyzing METs data. Best practice in METs analysis is to carry out a comparison of competing models with different variance-covariance structures. Improperly chosen variance-covariance structures may lead to biased estimation of means resulting in incorrect conclusions. In this work we focused on adaptive response of cultivars on the environments modeled by the LMMs with different variance-covariance structures. We identified possible limitations of inference when using an inadequate variance-covariance structure. In the presented study we used the dataset on grain yield for 63 winter wheat cultivars, evaluated across 18 locations, during three growing seasons (2008/2009-2010/2011) from the Polish Post-registration Variety Testing System. For the evaluation of variance-covariance structures and the description of cultivars adaptation to environments, we calculated adjusted means for the combination of cultivar and location in models with different variance-covariance structures. We concluded that in order to fully describe cultivars adaptive patterns modelers should use the unrestricted variance-covariance structure. The restricted compound symmetry structure may interfere with proper interpretation of cultivars adaptive patterns. We found, that the factor-analytic structure is also a good tool to describe cultivars reaction on environments, and it can be successfully used in METs data after determining the optimal component number for each dataset.

Abstract:
The energy-absorbing structure of a crashworthy railway vehicle was designed by combining the characteristics of thin-walled metal structures and aluminum honeycomb structures: finite element models of collisions involving energy-absorbing structures were built in ANSYS/LS-DYNA. In these models, the thin-walled metal structure was modeled as a plastic kinematic hardening material, and the honeycomb structure was modeled as an equivalent solid model with orthotropic–anisotropic mechanical properties. The analysis showed that the safe velocity standard for rail vehicle collisions was improved from 25 km/h to 45 km/h by using a combined energy-absorbing structure; its energy absorption exceeded the sum of the energy absorbed by the thin-walled metal structure and honeycomb structure when loaded separately, because of the interaction effects of thin-walled metal structure and aluminum honeycomb structure. For an aluminum honeycomb to the same specification, the composite structure showed the highest SEA when using a thin-walled metal structure composed of bi-grooved tubes, followed by that using single-groove tubes: that with a straight-walled structure had the lowest SEA.

Abstract:
Coastal process understanding is based on observations of physical processes in the field and laboratory from which theories are developed. Theories may be expressed mathematically and coded into numerical models. Compared with the cost of field data acquisition and laboratory experiments, the cost of numerical modelling is often perceived to be low. Therefore, there is a tendency to undertake coastal investigation and design using numerical modelling methods alone. However, there is still a need for physical modelling in coastal engineering.

Abstract:
We present and discuss properties of the following magnetic field models in a magnetic cloud: Miller and Turner solution, modified Miller–Turner solution, Romashets–Vandas toroidal and integral models, and Krittinatham–Ruffolo model. Helicity of the magnetic field in all the models is the main feature of magnetic clouds. The first three models describe the magnetic field inside an ideal torus. In the integral model, parameters of a generating torus ambiguously determine the volume and form of the magnetic field region. In the Krittinatham–Ruffolo model, the cross-section radius of the torus is variable, thereby it corresponds more closely to the real form of magnetic clouds in the inner heliosphere. These models can be used to interpret in-situ observations of the magnetic flux rope, to study a Forbush decrease in magnetic clouds and transport effects of solar energetic particles injected into a coronal mass ejection.

Full text
Abstract:
This paper extends the Capital Structure Model (CSM) research by performing the following tasks. First, a correction is offered on the corporate tax rate adjustment found in the break-through concept of the levered equity growth rate (gL) given by Hull (2010). This correction is important because gL links the plowback-payout and debt-equity choices and so its accuracy is paramount. Second, this paper introduces a retained earnings (RE) constraint missing from the CSM growth research when a firm finances with internal equity. The RE constraint governs the plowback-payout and debt-equity choices through the interdependent relation between RE and interest payments (I). Third, a by-product of the RE constraint is a second constraint that governs a no-growth situation so that I does not exceed the available cash flows. Fourth, with the gL correction and two constraints in place, updated applications of prior research and new applications are provided. These applications reveal lower gain to leverage (GL) values than previously reported with more symmetry around the optimal debt-to-equity ratio (ODE) while minimizing steep drop-offs in firm value. For larger plowback ratios, the optimal debt level choice can change. The new constraints serve to point out the need for further research to incorporate external financing within the CSM framework.

Full text
Abstract:
The three-dimensional (3D) structures of human leukocyte antigen (HLA) molecules are indispensable for the studies on the functions at molecular level. We have developed a homology modeling system named HLA-modeler specialized in the HLA molecules. Segment matching algorithm is employed for modeling and the optimization of the model is carried out by use of the PFROSST force field considering the implicit solvent model. In order to efficiently construct the homology models, HLA-modeler uses a local database of the 3D structures of HLA molecules. The structure of the antigenic peptide-binding site is important for the function and the 3D structure is highly conserved between various alleles. HLA-modeler optimizes the use of this structural motif. The leave-one-out cross-validation using the crystal structures of class I and class II HLA molecules has demonstrated that the rmsds of nonhydrogen atoms of the sites between homology models and crystal structures are less than 1.0 Å in most cases. The results have indicated that the 3D structures of the antigenic peptide-binding sites can be reproduced by HLA-modeler at the level almost corresponding to the crystal structures.

Abstract:
Genetic counselling is a complex process that helps people to understand and adopt medical, psychological and genetic aspects of the disease and enable them to make an appropriate decision. In this framework, we revisited all the existing models for decision-making and suggested their use in the process of genetic counselling, which may lead to more equitable and more favourable outcomes. Also, Donabedian's (Structure-Process-Outcome) model for the development of key performance indicators was applied to assess the quality in the process of genetic counselling. Quality indicators at SPO model in the process of genetic counselling were proposed. The social, economic and humanistic outcomes have also been identified. All defined quality indicators together represent a framework for monitoring, evaluation and continuous improvement of the process of genetic counselling. Although the new medical services of genetic counselling tend to be developed as a powerful multidisciplinary field, the implementation of quality management model will certainly help the development of collaborative practice.

Abstract:
This study deals with modeling for profile change due to damage progression of rubble mound revetment. The model profiles based on the experimental results consist of three datum points and two sine curves corresponding to the degree of deformation of the revetment. The model profiles agree well with the measured profiles. The model profiles are also used in other experiments and a time-averaged numerical model to examine the change of performance due to damage progression. The reflection coefficient and overtopping rate are taken as performance indices. The measured reflection coefficient decreases slightly, but the overtopping rate increases with damage progression of the revetment. The computed reflection coefficient is almost constant and the overtopping rate shows opposite tendency to the experimental result.

This paper presents laboratory experiments on scale models of marina breakwaters conducted to assess the effectiveness of an overspill basin in reducing wave overtopping. Six different breakwater models were tested under eight different wave conditions. The comparisons between the overtopping measurements on a classical shaped breakwater model and those conducted on models characterized by the inclusion of overspill basins have proved the effectiveness of this new design. Moreover, increasing the height of the wave wall up to the value that induces the same reduction of the overtopping obtained by the inclusion of overspill basins is also reviewed. Some analysis on mean overtopping discharges as well as analysis on maximum overtopping volumes are reported.

Abstract:
An automated method for constructing 3D models of class II MHC structures that uses constraint logic programming to select side-chain conformations is described. This method follows a comparative modeling approach in basing the model structures on experimentally determined MHC-peptide structures, but it uses constraints to ease open the peptide binding groove so that the modeled MHC structure is a less specific fit for the co-crystallized peptide in the starting structure. The resulting models are used by a "peptide threading" program that attempts to predict peptides from a protein sequence that will bind strongly to particular MHC alleles. Our results indicate that MHC models that have been constructed in this way enable the peptide threading program to make binding predictions that are comparable with those obtained when using experimentally determined MHC structures, suggesting that a combined modeling and peptide threading approach is worth pursuing for MHC molecules for which experimentally determined structures are not available.

Abstract:
The aim of this paper is to study the interaction between adjacent structures with different foundation levels under earthquake loading conditions. Structures and soil are represented by two different models. In the first case, the structure itself is modeled with standard frame element, whereas the soil behavior is stimulated by a special grid model. In the second case, the structure and soil are represented by plane stress or plane strain elements. The Interaction between the two structures is demonstrated and discussed via numerical examples using the proposed method and program. In case of the structures having shallow foundations, the interaction is small and negligible. If the foundation of one structure is shallow and the other one deep, then the interaction renders the forces in one structure 20% smaller than those in a single shallow structure, If the neighboring structures have the same deep foundation level, then due to interaction the forces in one structure are 25% larger than those in a single deep structure.

Abstract:
In this study, we address the issue of performing meaningful pKa calculations using homology modeled three-dimensional (3D) structures and analyze the possibility of using the calculated pKa values to detect structural defects in the models. For this purpose, the 3D structure of each member of five large protein families of a bacterial nucleoside monophosphate kinases (NMPK) have been modeled by means of homology-based approach. Further, we performed pKa calculations for the each model and for the template X-ray structures. Each bacterial NMPK family used in the study comprised on average 100 members providing a pool of sequences and 3D models large enough for reliable statistical analysis. It was shown that pKa values of titratable groups, which are highly conserved within a family, tend to be conserved among the models too. We demonstrated that homology modeled structures with sequence identity larger than 35% and gap percentile smaller than 10% can be used for meaningful pKa calculations. In addition, it was found that some highly conserved titratable groups either exhibit large pKa fluctuations among the models or have pKa values shifted by several pH units with respect to the pKa calculated for the X-ray structure. We demonstrated that such case usually indicates structural errors associated with the model. Thus, we argue that pKa calculations can be used for assessing the quality of the 3D models by monitoring fluctuations of the pKa values for highly conserved titratable residues within large sets of homologous proteins.

Abstract:
FEMDEM modelling which combines the multi-body particle interaction and motion modelling (i.e. Discrete Element Model, DEM) with the ability to model internal deformation of arbitrary shape (Finite Element Model, FEM) has been applied to breakwater models. There are two versions of a FEMDEM solver developed; Y3D_D is for deformable materials and is required for dynamic and static stress analysis and Y3D-R is the rigid version often used to numerically construct the armour unit packs. This paper also reports the placement protocols: POSITIT. FEMDEM modelling deals with solids interactions and is one modelling component that is to be coupled to other modelling technologies e.g. CFD, interface tracking, wave models, porous media etc. so that the key fluid-solid interactions can be modelled in a full scale virtual breakwater alongside work on scaled hydraulic laboratory models and prototype structures. The latest developments of two-way coupled interactions of waves with coastal structures are also described in this paper.
