description: В результате длительных исследований была установлена лечебная эффективность электромагнитного излучения (ЭМИ) крайне высокой частоты (КВЧ). Воздействие осуществляется преимущественно на акупунктурные точки или в проекции болевых проявлений на коже. Целью настоящего исследования является изучение реакции организма в биологически ак-тивных зонах (БАЗ) непосредственно после воздействия на них КВЧ-излучением.
В данном исследовании использовалась диагностика состояния БАЗ организма человека методом радиометрии. Появление диагностики, основанной на приеме собственного излучения организма человека в ММ-диапазоне ЭМИ позволило по-новому рассмотреть вопрос о времени воздействия ММ-излучения.
В статье делается заключение о том, что при ММ-воздействии любой частоты на БАЗ организма человека возникает отклик на частоте используемого для диагностики радиометра, не всегда совпадающей с частотой воздействия. Удалось определить время оптимального воздействия на БАЗ, при котором наблюдался отклик в виде возмущения с последующей нормализацией или возвращением к исходному состоянию.

description: We perform fully relativistic first principles calculations of the exchange interactions and the magnetocrystalline anisotropy energy (MAE) in an Fe/FePt/Fe sandwich system in order to elucidate how the presence of Fe/FePt (soft/hard magnetic) interfaces impacts on the magnetic properties of Fe/FePt/Fe multilayers. Throughout our study we make comparisons between a geometrically unrelaxed system and a geometrically relaxed system. We observe that the Fe layer at the Fe/FePt interface plays a crucial role inasmuch its (isotropic) exchange coupling to the soft (Fe) phase of the system is substantially reduced. Moreover, this interfacial Fe layer has a substantial impact on the MAE of the system. We show that the MAE of the FePt slab, including the contribution from the Fe/FePt interface, is dominated by anisotropic inter-site exchange interactions. Our calculations indicate that the change in the MAE of the FePt slab with respect to the corresponding bulk value is negative, i.e., the presence of Fe/FePt interfaces appears to reduce the perpendicular MAE of the Fe/FePt/Fe system. However, for the relaxed system, this reduction is marginal. It is also shown that the relaxed system exhibits a reduced interfacial exchange. Using a simple linear chain model we demonstrate that the reduced exchange leads to a discontinuity in the magnetisation structure at the interface.

description: We propose a new method of gravitational wave detection using a modified form of higher criticism, a statistical technique introduced by Donoho & Jin (2004). Higher criticism is designed to detect a group of sparse, weak sources, none of which are strong enough to be reliably estimated or detected individually. We apply higher criticism as a second-pass method to synthetic F-statistic and C-statistic data for a monochromatic periodic source in a binary system and quantify the improvement relative to the first-pass methods. We find that higher criticism on C-statistic data is more sensitive by ~6% than the C-statistic alone under optimal conditions (i.e. binary orbit known exactly) and the relative advantage increases as the error in the orbital parameters increases. Higher criticism is robust even when the source is not monochromatic (e.g. phase wandering in an accreting system). Applying higher criticism to a phase-wandering source over multiple time intervals gives a >30% increase in detectability with few assumptions about the frequency evolution. By contrast, in all-sky searches for unknown periodic sources, which are dominated by the brightest source, second-pass higher criticism does not provide any benefits over a first pass search

description: We present a new model extension for the Water balance Simulation Model, WaSiM, which features (i) snow interception and (ii) modified meteorological conditions under coniferous forest canopies, complementing recently developed model extensions for particular mountain hydrological processes. Two study areas in Austria and Germany are considered in this study. To supplement and constrain the modelling experiments with on-site observations, a network of terrestrial time-lapse cameras was set up in one of these catchments. The spatiotemporal patterns of snow depth inside the forest and at the adjacent open field sites were recorded along with snow interception dynamics. Comparison of observed and modelled snow cover and canopy interception indicates that the new version of WaSiM reliably reconstructs the variability of snow accumulation for both the forest and the open field. The Nash-Sutcliffe efficiency computed for selected runoff events in spring increases from −0.68 to 0.71 and 0.21 to 0.87, respectively.

description: В целях нейрофармакологического анализа восходящих влияний мезодиэнцефальной активирующей системы в условиях вибрации изучено влияние центрального М-холинолитика амизила на специфические таламо-корковые (ТК) и неспецифические гипоталамо-корковые (ГК) вызванные потенциалы (ВП). Регистрация ВП проводилась до и после введения амизила и на фоне воздействия вибрации. Использовалось внутривенное и внутримозговое введение препарата. На фоне медленных “амизиловых” волн наблюдались изменения вызванных ответов коры на стимуляцию релейного ядра таламуса и заднего гипоталамического ядра. При этом латентные периоды и длительность положительных и отрицательных фаз ВП достоверно не изменялись, а амплитуды первичных компонентов ответов возрастали. На фоне увеличения амплитуды ТК ВП, вызванной амизилом, кратковременная вибрация (30 мин) не оказывала существенного влияния на амплитудно-временны́е параметры вызванных ответов. При этом после 3-часовой вибрации на фоне амизила наблюдалось некоторое увеличение амплитуды ГК ВП, по сравнению с изолированным действием вибрации. Полученные данные свидетельствуют, что характер изменения ВП в различные фазы вибрации предопределяются сложным взаимодействием активирующих и тормозящих систем мозга.

description: For derived flood frequency analysis based on hydrological modelling long continuous precipitation time series with high temporal resolution are needed. Often, the observation network with recording rainfall gauges is poor, especially regarding the limited length of the available rainfall time series. Stochastic precipitation synthesis is a good alternative either to extend or to regionalise rainfall series to provide adequate input for long-term rainfall-runoff modelling with subsequent estimation of design floods. Here, a new two step procedure for stochastic synthesis of continuous hourly space-time rainfall is proposed and tested for the extension of short observed precipitation time series. First, a single-site alternating renewal model is presented to simulate independent hourly precipitation time series for several locations. The alternating renewal model describes wet spell durations, dry spell durations and wet spell intensities using univariate frequency distributions separately for two seasons. The dependence between wet spell intensity and duration is accounted for by 2-copulas. For disaggregation of the wet spells into hourly intensities a predefined profile is used. In the second step a multi-site resampling procedure is applied on the synthetic point rainfall event series to reproduce the spatial dependence structure of rainfall. Resampling is carried out successively on all synthetic event series using simulated annealing with an objective function considering three bivariate spatial rainfall characteristics. In a case study synthetic precipitation is generated for some locations with short observation records in two mesoscale catchments of the Bode river basin located in northern Germany. The synthetic rainfall data are then applied for derived flood frequency analysis using the hydrological model HEC-HMS. The results show good performance in reproducing average and extreme rainfall characteristics as well as in reproducing observed flood frequencies. The presented model has the potential to be used for ungauged locations through regionalisation of the model parameters.

description: The quantum spin Hall (QSH) state is a genuinely new state of matter characterized by a non-trivial topology of its band structure. Its key feature is conducting edge channels whose spin polarization has potential for spintronic and quantum information applications. The QSH state was predicted and experimentally demonstrated to exist in HgTe quantum wells. The existence of the edge channels has been inferred from the fact that local and non-local conductance values in sufficiently small devices are close to the quantized values expected for ideal edge channels and from signatures of the spin polarization. The robustness of the edge channels in larger devices and the interplay between the edge channels and a conducting bulk are relatively unexplored experimentally, and are difficult to assess via transport measurements. Here we image the current in large Hallbars made from HgTe quantum wells by probing the magnetic field generated by the current using a scanning superconducting quantum interference device (SQUID). We observe that the current flows along the edge of the device in the QSH regime, and furthermore that an identifiable edge channel exists even in the presence of disorder and considerable bulk conduction as the device is gated or its temperature is raised. Our results represent a versatile method for the characterization of new quantum spin Hall materials systems, and confirm both the existence and the robustness of the predicted edge channels.

description: Assessing the risk of yield loss in African drought-affected regions is key to identify feasible solutions for stable crop production. Recent studies have demonstrated that Copula-based probabilistic methods are well suited for such assessment owing to reasonably inferring important properties in terms of exceedance probability and joint dependence of different characterization. However, insufficient attention has been given to quantifying the probability of yield loss and determining the contribution of climatic factors. This study applies the Copula theory to describe the dependence between drought and crop yield anomalies for rainfed maize, millet, and sorghum crops in sub-Saharan Africa (SSA). The environmental policy integrated climate model, calibrated with Food and Agriculture Organization country-level yield data, was used to simulate yields across SSA (1980-2012). The results showed that the severity of yield loss due to drought had a higher magnitude than the severity of drought itself. Sensitivity analysis to identify factors contributing to drought and high-temperature stresses for all crops showed that the amount of precipitation during vegetation and grain filling was the main driver of crop yield loss, and the effect of temperature was stronger for sorghum than for maize and millet. The results demonstrate the added value of probabilistic methods for drought-impact assessment. For future studies, we recommend looking into factors influencing drought and high-temperature stresses as individual/concurrent climatic extremes. © 2022 The Author(s).

description: Das Akut-auf-chronisches Leberversagen ist mit Organversagen und einer hohen Kurzzeitsterblichkeit verbunden, wobei chirurgische Eingriffe und bakterielle Infektionen Risikofaktoren für die Entwicklung eines ACLF darstellen. Postoperative bakterielle Infektionen nach elektiven Eingriffen an Patienten mit Leberzirrhose sowie deren Einfluss auf die ACLF-Entwicklung wurden bisher allerdings noch nicht im Detail charakterisiert und untersucht. Im Rahmen dieser retrospektiven monozentrischen Studie wurden daher die postoperative ACLF- und Infektionsentwicklung innerhalb von 28 Tagen sowie die postoperative Dreimonatssterblichkeit an 235 Patienten mit Leberzirrhose untersucht, die sich einem elektiven chirurgischen Eingriff unterzogen und zum Zeitpunkt des Eingriffes weder ein ACLF noch Zeichen einer Infektion aufwiesen. Die Identifizierung von Risikofaktoren für diese Endpunkte wurde mittels Cox Regressionsanalyse durchgeführt.
 Insgesamt entwickelten 86 Patienten (37 %) ein postoperatives ACLF innerhalb von 28 Tagen, wobei Patienten mit postoperativen Infektionen signifikant häufiger ein ACLF entwickelten als solche ohne Infektion (51 % bzw. 24 %, p < 0,001) und auch eine höhere Dreimonatssterblichkeit aufwiesen (p < 0,05). Als bedeutendste Risikofaktoren für die ACLF-Entwicklung stellten sich neue postoperative Infektionen im Allgemeinen (HR 2,41; 95 % KI 1,58 – 3,69; p < 0,001) und SSI mit Organbeteiligung im Speziellen heraus (HR 2,59; 95 % KI 1,32 – 5,07; p < 0,01). Umfangreiche chirurgische Eingriffe indes stellten einen unabhängig mit der postoperativen Entwicklung einer Infektion assoziierten Risikofaktor dar. Die adäquate initiale empirische Antibiotikatherapie einer Infektion wirkte sich prognostisch günstig auf die postoperative Sterblichkeit aus.
 Somit wurden mittels dieser Studie postoperative bakterielle Infektionen und insbesondere SSI mit Organbeteiligung charakterisiert und als mit der Entwicklung eines ACLF nach elektiven chirurgischen Eingriffen assoziierte Risikofaktoren bei Patienten mit Leberzirrhose identifiziert. Dabei führte das gemeinsame Auftreten dieser beiden Faktoren zu einer höheren Kurzzeitsterblichkeit als die Faktoren für sich allein gestellt, sodass interdisziplinäre Betreuung, die frühe Erkennung postoperativer Infektionen und eines ACLF sowie eine adäquate initiale Antibiotikatherapie wichtig und notwendig sind, um das postoperative Outcome zu verbessern.

description: Раскрыта актуальность исследования электрохирургических методов резекции новообразований век, выполнено сравнение с другими методами, применяемыми на практике, а также проанализированы недостатки, имеющиеся на данный момент с возможными последствиями, основным из которых является неправильный подбор параметров воздействия. В итоге сформулированы основные задачи работы: теоретическое исследование процесса радиоволновой резекции и, на основании этого, определение влияния основных параметров воздействия на максимальную температуру биоткани.
Для решения поставленной задачи разработана геометрическая модель органа зрения, включающая в себя глаз, веко, глазницу и новообразование с электродом. Также предложена математическая модель на основании уравнений непре-рывности и теплопроводности Фурье, а также начальных и граничных условий. Приведены используемые электрические и физические параметры органа зрения. На базе разработанной модели проведен вычислительный эксперимент по изучению влияния амплитуды воздействия и длительности воздействия на температуру нагрева биоткани при удалении но-вообразований век в среде Comsol Multiphysics. По результатам моделирования получены распределение электрического потенциала в модели, распределение температуры в зоне хирургического вмешательства, зависимость температуры от глубины проникновения в глаз, а также зависимость амплитуды воздействующего сигнала от длительности воздействия для достижения необходимых температур резекции и коагуляции, составляющих соответственно 112 °С и 60…80 °С. Приведены также численные результаты исследования, а именно значения максимальной температуры в зоне хирургического вмешательства при различных амплитуде и длительности воздействия.
На основании проведенного исследования был сделан вывод о значениях применяемых параметров воздействия для достижения необходимых температур резекции и коагуляции при данной геометрии электрода и частоте воздействия 2,64 МГц. Также удалось установить глубину расположения максимальной температуры и ее соотношение с границей раздела «электрод-биоткань».

description: In this case study, we present the implementation of a finite element method (FEM)-based numerical pore-scale model that is able to track and quantify the propagating fluid–fluid interfacial area on highly complex micro-computed tomography (μ-CT)-obtained geometries. Special focus is drawn to the relationship between reservoir-specific capillary pressure (pc), wetting phase saturation (Sw) and interfacial area (awn). The basis of this approach is high-resolution μ-CT images representing the geometrical characteristics of a georeservoir sample. The successfully validated 2-phase flow model is based on the Navier–Stokes equations, including the surface tension force, in order to consider capillary effects for the computation of flow and the phase-field method for the emulation of a sharp fluid–fluid interface. In combination with specialized software packages, a complex high-resolution modelling domain can be obtained. A numerical workflow based on representative elementary volume (REV)-scale pore-size distributions is introduced. This workflow aims at the successive modification of model and model set-up for simulating, such as a type of 2-phase problem on asymmetric μ-CT-based model domains. The geometrical complexity is gradually increased, starting from idealized pore geometries until complex μ-CT-based pore network domains, whereas all domains represent geostatistics of the REV-scale core sample pore-size distribution. Finally, the model can be applied to a complex μ-CT-based model domain and the pc–Sw–awn relationship can be computed.

description: In this paper a road network extraction algorithm for suburban areas is presented. The algorithm uses colour infrared (CIR) images and digital surface models (DSM). The CIR data allow a good separation between vegetation and roads. The image is first segmented in two steps: an initial segmentation using the normalized cuts algorithm and a subsequent grouping of the segments. Road parts are extracted from the segments and then first connected locally to form subgraphs, because roads are often not extracted as a whole due to disturbances in their appearance. Subgraphs can contain several branches, which are resolved by a subsequent optimisation. The optimisation uses criteria describing the relations between the road parts as well as context objects such as trees, vehicles and buildings. The resulting road strings, represented by their centre lines, are then connected to a road network by searching for junctions at the ends of the roads. Small isolated roads are eliminated because they are likely to be false extractions. Results are presented for three image subsets coming from two different data sets, and a quantitative analysis of the completeness and correctness is shown from nine image subsets from the two data sets. The results show that the approach is suitable for the extraction of roads in suburban areas from aerial images.

description: Parking search traffic causes increased travel times and air pollution in many cities. Real-time parking availability maps are expected to help drivers to find a parking space faster and thus to reduce parking search traffic. A possibility to create such maps is the aggregation of parking availability information from crowdsourcing solutions like probe vehicles and mobile phone applications. Since these sources cannot sense the whole city at the same time, estimation methods are necessary to fill uncovered areas. This paper investigates the estimation of parking availability based on spatial methods using sensor data from San Francisco. First, spatial similarities in parking availability are evaluated for different aspects like time of day and number of parking spaces depending on the distance to reveal the parking characteristics. Then, interpolation methods are examined to estimate parking availability in unobserved road segments. Results show that relevant similarities mainly exist for short distances of less than hundred meters. Their similarity values are lower than the temporal similarity even for multiple hours of time gap. Nevertheless, spatial information is useful to interpolate parking availability. Investigated interpolation methods show significantly better results than random guess. Inverse distance weighting method outperforms a simple averaging by up to 5%.

description: Fully integrated three-dimensional (3D) physically based hydrologic models usually require many computational resources. For many applications, simplified models can be a cost-effective alternative. The 3D models of subsurface flow are often simplified by coupling a 2D groundwater model with multiple 1D models for the unsaturated zone. The crucial part of such models is the coupling between the two model compartments. In this work we compare two approaches for the coupling. One is iterative where the 1D unsaturated zone models go down to the impervious bottom of the aquifer, and the other one is non-iterative and uses a moving lower boundary for the unsaturated zone. In this context we also propose a new way of treating the specific yield, which plays a crucial role in linking the unsaturated and the groundwater model. Both models are applied to three test cases with increasing complexity and analyzed in terms of accuracy and speed compared to fully integrated model runs. The non-iterative approach is faster but does not yield a good accuracy for the model parameters in all applied test cases, whereas the iterative one gives good results in all cases. Which strategy is applied depends on the requirements: computational speed vs. model accuracy.

description: Daily hydrological models are commonly used to study changes in flood peaks due to climate change. Although they often lead to an underestimation of absolute floods, it is assumed that future flood peaks in smaller mesoscale catchments are less underestimated when examining the relative change signal of floods. In this study, the applicability of this hypothesis is investigated by comparing the results of a daily hydrological model set, calibrated on runoff hydrographs, with an hourly model set calibrated on flood peak distributions. For analysis, a daily RCP8.5 climate model ensemble is disaggregated to hourly values and the runoff is simulated on a daily and hourly basis for six mesoscale catchments in Central Germany. Absolute floods and relative flood changes are compared between both model sets. The results show significant differences between the absolute floods of both model sets, in most cases caused by underestimations due to the daily modeling process. In contrast, the differences between the two model sets are not significant for the relative change signal of the floods, especially for higher return periods. To improve results in climate studies with coarse modeling time step, the use of relative change signal of floods instead of absolute values is recommended.
Finite size effects in the Z_2 spin liquid on the kagome lattice

description: Motivated by the recent discovery of the Z_2 quantum spin liquid state in the nearest neighbor Heisenberg model on the kagome lattice, we investigate the "even-odd" effect occuring when this state is confined to infinitely long cylinders of finite circumference. We pursue a dual analysis, where we map the effective Z_2 gauge theory from the kagome lattice to a frustrated Ising model on the dice lattice. Unexpectedly, we find that the latter theory, if restricted to nearest neighbor interactions, is insufficient to capture this effect. We provide an explanation of why further neighbor interactions are needed via a high-temperature expansion of the effective Hamiltonian. We then carry out projective symmetry group analysis to understand which second neighbor interactions can be introduced while respecting the lattice symmetries. Finally, we qualitatively compare our results to numerics by computing the dimerization operator within our theory. Systems with odd circumferences exhibit a non-vanishing dimerization that decays exponentially with circumference.

description: In this paper, we unravel the mechanisms responsible for the development of the two-channel system in the Outer Weser Estuary. A process-based morphodynamic model is built based on a flat-bed approach using simplified boundary conditions and accelerated morphological development. The results are analyzed in two steps: first, by checking for morphodynamic equilibrium in the simulations and second, by applying a newly developed method that interprets simulations based on categorization of the two-channel system and cross-sectional correlation analysis. All simulations reach a morphodynamic equilibrium and develop two channels that vary considerably over time and between the simulations. Variations can be found in the location and depth of the two channels, the development of the dominant channel over time and the alteration in the dominance pattern. The conclusions are that the development of the two-channel system is mainly caused by the tides and the basin geometry. Furthermore, it is shown that the alternation pattern and period are dependent on the dominance of the tides compared to the influence of river discharge.
Temporal and spatial interference in molecular above-threshold ionization with elliptically polarized fields

description: We investigate direct above-threshold ionization in diatomic molecules, with particular emphasis on how quantum interference is altered by a driving field of non-vanishing ellipticity. This interference may be either temporal, i.e., related to ionization events occurring at different times, or spatial, i.e., related to the electron emission at different centers in the molecule. Employing the strong-field approximation and saddle-point methods, we find that, in general, for non-vanishing ellipticity, there will be a blurring of the temporal and spatial interference patterns. The former blurring is caused by the electron velocity component perpendicular to the major polarization axis, while spatial interference is washed out as a consequence either of s-p mixing, or of the temporal dependence of the ionization prefactor. Both types of interference are analyzed in detail in terms of electron trajectories, and specific conditions for which sharp fringes occur are provided.

Effect of bulk Lorentz violation on anisotropic brane cosmologies

description: The effect of Lorentz invariance violation in cosmology has attracted a considerable amount of attention. By using a dynamical vector field assumed to point in the bulk direction, with Lorentz invariance holding on the brane, we extend the notation of Lorentz violation in four dimensions to a five-dimensional brane-world. We obtain the general solution of the field equations in an exact parametric form for Bianchi type I space-time, with perfect fluid as a matter source. We show that the brane universe evolves from an isotropic/anisotropic state to an isotropic de Sitter inflationary phase at late time. The early time behavior of anisotropic brane universe is largely dependent on the Lorentz violating parameters $β_i, i = 1, 2, 3$ and the equation of state of the matter, while its late time behavior is independent of these parameters.

description: Предложен комплексный метод для определения ряда физических, химических и медико-биологических свойств, составов веществ и особенностей живых организмов путем исследования взаимодействия и физических механизмов взаимодействия электромагнитных полей с живыми и водосодержащими объектами. Комплексный метод определения свойств объектов состоит из двух разделов. Первый раздел метода включает в себя выявление физических свойств индуцированного электромагнитного излучения в СВЧ- и мм-диапазонах радиочастот (радиоотклика) на внешнее электромагнитное воздей-ствие. Экспериментально показано, что физические параметры радиоотклика имеют функциональную зависимость от фи-зических, химических и медико-биологических свойств исследуемых субстанций. Установлены основные параметры ра-диоотклика, меняющиеся при вариации комплексных свойств веществ. Второй раздел метода включает в себя исследование люминесцентного и спонтанного излучения живых и водосодержащих веществ радиодиапазона до и после воздействия электромагнитных полей СВЧ- и мм-диапазонов длин волн на исследуемые объекты. В экспериментах показано, что Фурье-спектры и фазовые портреты радиояркостных характеристик электромагнитного излучения меняют свои свойства в зависимости от физических, химических и медико-биологических свойств исследуемых систем.
Таким образом показано, что метод установления физических свойств и параметров люминесцентного, спонтанного и вынужденного электромагнитного излучения радиодиапазона может явиться способом определения расширенного ряда свойств как биологических, так и водосодержащих субстанций.

description: Постановка проблемы. Развитие новых подходов к моделированию динамики сложных эволюционирующих систем (ЭС) открывает перспективы создания интеграционных теорий и концептуальных решений при построении нового курса современной компьютерной математики (СКМ), приложения которого обеспечивают интерпретацию динамических ситуаций в режиме экстренных вычислений. Вычислительный комплекс СКМ рассмотрен как новая парадигма интерпретации динамики ЭС, как своеобразный «мостик» между классической дискретной математикой и формальным аппаратом интеллектуальных технологий ХХI века.
Цель. Анализ проблемы использования теоретических принципов и концептуальных решений в вычислительной среде современной компьютерной математики.
Результаты. Обсуждены основные вопросы, связанные с применением достижений нейросетевых технологий в математическом аппарате СКМ при интерпретации ЭС в пространствах поведения и управления современной теории катастроф. Отмечено, что особый теоретический интерес представляет интеграция методов и моделей вычислительной среды СКМ при интеллектуальной поддержке процедур построения интеллектуальных систем новых поколений, функционирующих в режиме экстренных вычислений.
Практическая значимость. Рассмотрение СКМ как эффективного инструмента интерпретации динамики сложных систем позволяет более гибко и адекватно описывать феномен поведения в условиях неопределенности и неполноты исходной информации.

description: Discussions on academic integrity mainly focus on the transparency and replicability of research. Both these factors require access to qualitative or quantitative research data, detailed descriptions of research materials and approaches, and an overview of the data processing and publication processes. This document provides guidelines for archiving academic publications as well as the information needed to replicate the results discussed in such publications. This document thus relates to the archiving of published academic research and should not be regarded as guidelines concerning data management, data processing agreements and privacy aspects. The document can be seen as an initiative that is part of a broader effort to promote academic integrity among researchers focusing on quantitative and qualitative studies at faculties of Behavioural and Social Sciences in the Netherlands. Rather than functioning as a strict straitjacket, it intends to provide a clear orientation, which can be further fleshed out under the motto 'apply or explain' for each individual faculty depending on its circumstances.
