description: Use case scenarios are created during the analysis phase to specify software system requirements and can also be used for creating system level test cases. Using use cases to get system tests has several benefits including test design at early stages of software development life cycle that reduces over all development cost of the system. Current approaches for system testing using use cases involve functional details and does not include guards as passing criteria i.e. use of class diagram that seem to be difficult at very initial level which lead the need of specification based testing without involving functional details. In this paper, we proposed a technique for system testing directly derived from the specification without involving functional details. We utilize initial and post conditions applied as guards at each level of the use cases that enables us generation of formalized test cases and makes it possible to generate test cases for each flow of the system. We used use case scenarios to generate system level test cases, whereas system sequence diagram is being used to bridge the gap between the test objective and test cases, derived from the specification of the system. Since, a state chart derived from the combination of sequence diagrams can model the entire behavior of the system.Generated test cases can be employed and executed to state chart in order to capture behavior of the system with the state change.All these steps enable us to systematically refine the specification to achieve the goals of system testing at early development stages.

description: We study the galaxy stellar mass function in different environments in the local Universe, considering both the total mass function and that of individual galaxy morphological types. We compare the mass functions of galaxies with $\rm log_{10} M_{\star}/M_{\odot} \geq 10.25$ in the general field and in galaxy groups, binary and single galaxy systems from the Padova-Millennium Galaxy and Group Catalogue at $z=0.04-0.1$ with the mass function of galaxy clusters of the WIde-field Nearby Galaxy-Cluster Survey at $z=0.04-0.07$. Strikingly, the variations of the mass function with global environment, overall, are small and subtle. The shapes of the mass functions of the general field and clusters are indistinguishable, and only small, statistically insignificant variations are allowed in groups. Only the mass function of our single galaxies, representing the least massive haloes and comprising less than a third of the general field population, is proportionally richer in low-mass galaxies than other environments. The most notable environmental effect is a progressive change in the upper galaxy mass, with very massive galaxies found only in the most massive environments. This environment-dependent mass cut-off is unable to affect the Schechter parameters and the K-S test, and can only be revealed by an ad-hoc analysis. Finally, we show how, in each given environment, the mass function changes with morphological type, and that galaxies of the same morphological type can have different mass functions in different environments.

description: Biopharmazeutika haben heutzutage ein breites Anwendungsgebiet in der medizinischen Versorgung. Zur biotechnologischen Produktion dieser therapeutischen Proteine werden vor allem gentechnisch modifizierte Säugetierzellen eingesetzt. Säugetierzellen sind hoch empfindliche biologische Systeme, die sich nur bei idealen Umgebungsbedingungen vermehren und ein Produkt bilden. Um die richtigen Bedingungen während der Kultivierung von Zellen stets zu erfüllen, hat die Bioprozessüberwachung eine entscheidende Bedeutung. Dabei besteht die besondere Herausforderung, viele Größen, bei oft niedrigen Konzentrationen, über einen langen Zeitraum zu überwachen. Eine gute Möglichkeit zur Überwachung solcher Größen stellt die Spektroskopie dar. Diese Arbeit beschreibt die Evaluierung der 2D-Fluoreszenz-, der UV/VIS-, und der Raman-Spektroskopie zur Überwachung von Säugetierzellkultivierungen. Im ersten Teil der Arbeit wurde untersucht welche im Bioprozess relevanten Analyten nebeneinander in komplexen Lösungen mit den verschiedenen spektroskopischen Methoden detektiert werden können. Es konnte gezeigt werden, dass mit Hilfe der spektroskopischen Methoden unterschiedliche Analyten simultan nebeneinander detektiert werden können. Außerdem wurde im Rahmen dieser Arbeit ein SIP- (engl. Sterilization-in-Place) Bypass-System entwickelt, welches die Adaption spektroskopischer Sensoren an unterschiedliche Reaktorsysteme ermöglicht, ohne die Sterilität zu gefährden. Die sterile Adaption der Sensoren konnte an die sonst nicht zugänglichen Glasbioreaktoren mit dem SIP-Bypass-System ermöglicht werden. Im Hauptteil der Arbeit wurden die spektroskopischen Methoden zur Echtzeitüberwachung von CHO-Zellkultivierungen evaluiert. Mit Hilfe der multivariaten Datenanalyse wurden Kalibrationsmodelle für verschiedene Analyten erstellt. Die Modelle wurden zur Vorhersage von Analyten in weiteren Kultivierungen eingesetzt. Die Ergebnisse zeigen, dass unter anderem schwer zugängliche Größen, wie die metabolische Aktivität und die Viabilität der Zellen, durch die Spektroskopie überwacht werden können. Zudem konnte gezeigt werden, dass anhand der Spektraldaten Prozessabweichungen frühzeitig über Prozesstrajektorien erkannt werden können.

description: Non-Local Attention (NLA) brings significant improvement for Single Image Super-Resolution (SISR) by leveraging intrinsic feature correlation in natural images. However, NLA gives noisy information large weights and consumes quadratic computation resources with respect to the input size, limiting its performance and application. In this paper, we propose a novel Efficient Non-Local Contrastive Attention (ENLCA) to perform long-range visual modeling and leverage more relevant non-local features. Specifically, ENLCA consists of two parts, Efficient Non-Local Attention (ENLA) and Sparse Aggregation. ENLA adopts the kernel method to approximate exponential function and obtains linear computation complexity. For Sparse Aggregation, we multiply inputs by an amplification factor to focus on informative features, yet the variance of approximation increases exponentially. Therefore, contrastive learning is applied to further separate relevant and irrelevant features. To demonstrate the effectiveness of ENLCA, we build an architecture called Efficient Non-Local Contrastive Network (ENLCN) by adding a few of our modules in a simple backbone. Extensive experimental results show that ENLCN reaches superior performance over state-of-the-art approaches on both quantitative and qualitative evaluations.

description: Steuersysteme befinden sich weltweit in einem fortlaufenden Wandel. Sich verändernde Rahmenbedingungen sowie politische oder gesellschaftliche Vorstellungen setzen die existenten Systeme unter Druck. In diesem Umfeld unternimmt diese Arbeit einen Versuch, große Reformvorschläge nationaler Steuersysteme zu untersuchen und zu bewerten. Hierbei erfolgt nicht nur eine Analyse der enthaltenen Veränderungen im Verhältnis zum geltenden Recht bzw. abstrakten Zielgrößen, sondern auch ein Vergleich bezüglich der Methodik bzw. Herangehensweise an eine Steuerreform an sich. Untersucht werden Reformschläge des Mirrlees Committee betreffend das gesamte britische Steuersystem sowie der Stiftung Marktwirtschaft bezüglich Teilen des deutschen Steuersystems. Ergebnis der Analyse ist, dass Reformvorschläge im Verhältnis zum geltenden Recht allzu idealisierende bzw. vereinfachende Annahmen über die Rahmenbedingungen und Detailwirkungen der Steuergesetze machen. Vermeintliche Verbesserungen lassen sich derart leicht präsentieren, sie würden bei einer realen Umsetzung jedoch wahrscheinlich große Enttäuschung auslösen. Auch auf der fiskalischen Seite machen es sich Steuerreformvorschläge oftmals zu einfach. Um möglichst attraktiv zu wirken, wird das Steueraufkommen im Wege der Reform gesenkt und ein Ausgleich über angebliche Effizienz- oder Wachstumseffekte angestrebt. Beides stellt keinen ehrlichen Umgang mit dem Steuersystem dar und beruht zumeist auf nur kurzfristig wirksamen, internationalen Verschiebungen. Bezüglich der Methodik kommt die Arbeit zu dem Ergebnis, dass breiter aufgestellte Reformgruppen, die möglichst konkrete Reformvorschläge auf Basis sowohl ökonomischer als auch juristischer Überlegungen erstellen, zu umsetzungsgeeigneteren Reformvorschlägen kommen. Auch diese haben jedoch das Problem, welches jedem, insbesondere großen, Reformvorschlag innewohnt, dass die Qualität eines langjährig erprobten und gewachsenen Steuersystems einen hohen immanenten Wert besitzt.
Braid groups and mapping class groups for 2-orbifolds

Subjects: subject: 510

description: The main achievement of this thesis is that pure orbifold braid groups fit into an exact sequence 1$\\rightarrow$ $K$$\\rightarrow$$\\pi_1^{^{orb}}$($\\Sigma_\\Gamma$($n-1+L$))$\\xrightarrow{\\iota_{PZ_n}}$$PZ_n$($\\Sigma_\\Gamma$($L$))$\\xrightarrow{\\pi_{PZ_n}}$$PZ_{n-1}$($\\Sigma_\\Gamma$($L$))$\\rightarrow$1.

 In particular, we observe that the kernel $K$ of $\iota_{PZ_n}$ is non-trivial. This corrects Theorem 2.14 in [42]. Using the relation pictured in the figure on the title page, we construct non-trivial elements in the kernel. Moreover, we determine $K$. For this purpose, we introduce orbifold mapping class groups (with marked points) and establish a Birman exact sequence for them. Comparing the orbifold mapping class groups with the orbifold braid groups, reveals a surprising behavior: in contrast to the classical case, the orbifold braid group is a proper quotient of the orbifold mapping class group. In particular, this yields a presentation of the pure orbifold braid group which allows us to determine the kernel $K$.

 Furthermore, we generalize a result of Allcock [2] about Artin groups contained in orbifold braid groups and we analyze the connectivity of bipartite matching complexes of $\Gamma$-arcs. This allows us to deduce highly generating families of subgroups in Map$_n^{id,orb}$($\\Sigma_\\Gamma$($L$)). For $Z_n$($\\Sigma_\\Gamma$($L$)) and the contained Artin groups, we also obtain a highly generating family of subgroups.

description: We investigate a CME propagating towards Earth on 29 March 2011. This event is specifically chosen for its predominately northward directed magnetic field, so that the influence from the momentum flux onto Earth can be isolated. We focus our study on understanding how a small Earth-directed segment propagates. Mass images are created from the white-light cameras onboard STEREO which are also converted into mass height-time maps (mass J-maps). The mass tracks on these J-maps correspond to the sheath region between the CME and its associated shock front as detected by in situ measurements at L1. A time-series of mass measurements from the STEREO COR-2A instrument are made along the Earth propagation direction. Qualitatively, this mass time-series shows a remarkable resemblance to the L1 in situ density series. The in situ measurements are used as inputs into a 3D magnetospheric space weather simulation from CCMC. These simulations display a sudden compression of the magnetosphere from the large momentum flux at the leading edge of the CME and predictions are made for the time-derivative of the magnetic field (dB/dt) on the ground. The predicted dB/dt were then compared with observations from specific equatorially-located ground stations and show notable similarity. This study of the momentum of a CME from the Sun down to its influence on magnetic ground stations on Earth is presented as preliminary proof of concept, such that future attempts may try to use remote sensing to create density and velocity time-series as inputs to magnetospheric simulations.

description: Research on quantum magnetism with ultra-cold gases in optical lattices is expected to open fascinating perspectives for the understanding of fundamental problems in condensed-matter physics. Here we report on the first realization of quantum magnetism using a degenerate dipolar gas in an optical lattice. In contrast to their non-dipolar counterparts, dipolar lattice gases allow for inter-site spin-spin interactions without relying on super-exchange energies, which constitutes a great advantage for the study of spin lattice models. In this paper we show that a chromium gas in a 3D lattice realizes a lattice model resembling the celebrated t-J model, which is characterized by a non-equilibrium spinor dynamics resulting from inter-site Heisenberg-like spin-spin interactions provided by non-local dipole-dipole interactions. Moreover, due to its large spin, chromium lattice gases constitute an excellent environment for the study of quantum magnetism of high-spin systems, as illustrated by the complex spin dynamics observed for doubly-occupied sites.

description: Metallicity is the first parameter to influence the horizontal branch (HB) morphology of globular clusters (GCs). It has been found, however, that some other parameters may also play an important role in affecting the morphology. While the nature of these important parameters remains unclear, they are believed to be likely correlated with wind mass-loss of red giants, since this mass loss determines their subsequent locations on the HB. Unfortunately, the mass loss during the red giant stages of the stellar evolution is poorly understood at present. The stellar winds of red giants may be tidally enhanced by companion stars if they are in binary systems. We investigate evolutionary consequences of red giants in binaries by including tidally enhanced stellar winds, and examine the effects on the HB morphology of GCs. We find that red, blue, and extreme horizontal branch stars are all produced under the effects of tidally enhanced stellar wind without any additional assumptions on the mass-loss dispersion. Furthermore, the horizontal branch morphology is found to be insensitive to the tidal enhancement parameter, Bw. We compare our theoretical results with the observed horizontal branch morphology of globular cluster NGC 2808, and find that the basic morphology of the horizontal branch can be well reproduced. The number of blue horizontal branch stars in our calculations, however, is lower than that of NGC 2808.

Debris discs around M stars: non-existence versus non-detection

description: Motivated by the reported dearth of debris discs around M stars, we use survival models to study the occurrence of planetesimal discs around them. These survival models describe a planetesimal disc with a small number of parameters, determine if it may survive a series of dynamical processes and compute the associated infrared excess. For the WISE satellite, we demonstrate that the dearth of debris discs around M stars may be attributed to the small semi-major axes generally probed if either: 1. the dust grains behave like blackbodies emitting at a peak wavelength coincident with the observed one; 2. or the grains are hotter than predicted by their blackbody temperatures and emit at peak wavelengths that are shorter than the observed one. At these small distances from the M star, planetesimals are unlikely to survive or persist for time scales of 300 Myr or longer if the disc is too massive. Conversely, our survival models allow for the existence of a large population of low-mass debris discs that are too faint to be detected with current instruments. However, our interpretation becomes less clear and large infrared excesses are allowed if only one of these scenarios holds: 3. the dust grains are hotter than blackbody and predominantly emit at the observed wavelength; 4. or are blackbody in nature and emit at peak wavelengths longer than the observed one. Both scenarios imply that the parent planetesimals reside at larger distances from the star than inferred if the dust grains behaved like blackbodies. In all scenarios, we show that the infrared excesses detected at 22 and 70 microns from AU Mic are easily reconciled with its young age. We elucidate the conditions under which stellar wind drag may be neglected when considering dust populations around M stars. The WISE satellite should be capable of detecting debris discs around young M stars with ages on the order of 10 Myr.

title: Worldwide diffusion of solar photovoltaic panels and the role of state incentive: perspectives based on diffusion models
Creators: name: Bunea, Anita Mariana
Publisher: name: IMT Alti Studi Lucca
Year: 2019

description: The main goal of this thesis is to use the diffusion models to improve our
 understanding of SPP markets, with special focus on (a) identifying the main
 determinants of the diffusion of solar photovoltaic panels worldwide,
 particularly the role played so far by public incentives, (b) characterising the
 scale and temporal profiles of the major domestic shocks in SPP markets which
 mostly occurred after 2007, (c) discussing the resulting perspectives, and the
 involved role of public policies, for the future development of the market.
 Chapter 1 is introductory and preparatory for subsequent ones and pinpoints
 that (a) the presence of shocks is an intrinsic and often dominating feature of
 energy markets, thereby motivating the use of tools as the GBM, (b) only a few
 countries have developed long-term energy plans towards which to manage
 consistently their short-medium term policies, (c) the concept of energy
 framework was useful to indicated a number of commonalities among
 countries.
 The main findings of Chapter 2 were the following: i) essentially everywhere
 the effectiveness of media communication proved negligible, ii) the early phase
 where the growth of the market was completely sustained by internal
 communication only, iii) major changes in the market adoption curves have
 occurred in the form of massive positive shocks which took place between 2006
 and 2016 possibly following incentive measures in the various states, iv)
 inspection of the parameter estimates describing the temporal pattern of the
 shocks showed a lack of temporal persistence of the effects of incentive as well
 as a sharp trade-off between intensity and persistence of the actions.
 The results of Chapter 3 show that the SPP residential market in UK suffers not
 only the structural difficulties of this sector, but also the possible perception of
 relative penalisation suffered by late cohorts of adopters compared to the past
 cohorts who benefited higher rates of FIT. In the commercial and utility sectors
 the imitation rate is higher which might be explained by the fact that firms
 make more rational decisions based on economic factors rather than being led
 by perceptions.

description: We present three years of long-cadence and over one year of short-cadence photometry of the central star of the Planetary Nebula NGC 6826 obtained with the Kepler spacecraft, and temporally coinciding optical spectroscopy. The light curves are dominated by incoherent variability on time scales of several hours, but contain a lower-amplitude periodicity of 1.23799 d. The temporal amplitude and shape changes of this signal are best explicable with a rotational modulation, and are not consistent with a binary interpretation. We argue that we do not observe stellar pulsations within the limitations of our data, and show that a binary central star with an orbital period less than seven days could only have escaped our detection in the case of low orbital inclination. Combining the photometric and spectroscopic evidence, we reason that the hourly variations are due to a variable stellar wind, and are global in nature. The physical cause of the wind variability of NGC 6826 and other ZZ Leporis stars is likely related to the mechanism responsible for wind variations in massive hot stars.

title: Critical Phenomena in Multilayer Networks
Creators: name: Rapisardi, Giacomo
Publisher: name: IMT Alti Studi Lucca
Year: 2019

description: Network science has provided a set of powerful theoretical
 results for the description of critical phenomena in complex
 systems. These represent fundamental tools for the design
 and control of real networked systems with concrete and practical applications. Many of these results have been, however, formulated in the framework of independent networks,
 i.e., closed systems that do not interact with nor depend on
 other networks. This is a weak hypothesis because in the realworld networks cannot be considered as independent entities. For instance, critical infrastructure are very often and
 intentionally coupled together: the functioning of the networks of water and food supply, communications, fuel, financial transactions and power generation and transmission
 depend one on the other. For this reason, many of the classical
 results of network science have been questioned, and recent
 research has provided evidence that many of the results valid
 for isolated networks are indeed not verified for interacting
 (or so called multilayer) networked systems. With this thesis
 we present new results in the field of both linear and nonlinear dynamical processes in the context of multilayer networks, namely diffusion and percolation. While diffusion is
 naturally related to the concept of walks and navigability of
 a network, percolation addresses the concept of stability and
 resilience of a network under random and targeted attacks.

Using this method we revisit the Karch-O'Bannon's procedure to calculate the DC conductivity in the presence of constant electric and magnetic fields for backgrounds where the boundary is four or three dimensional and satisfies homogeneity and isotropy. We find a frame-independent expression for the DC conductivity tensor. For particular backgrounds we recover previous results on holographic metals and strange metals.

description: Reference-based super-resolution (RefSR) has made significant progress in producing realistic textures using an external reference (Ref) image. However, existing RefSR methods obtain high-quality correspondence matchings consuming quadratic computation resources with respect to the input size, limiting its application. Moreover, these approaches usually suffer from scale misalignments between the low-resolution (LR) image and Ref image. In this paper, we propose an Accelerated Multi-Scale Aggregation network (AMSA) for Reference-based Super-Resolution, including Coarse-to-Fine Embedded PatchMatch (CFE-PatchMatch) and Multi-Scale Dynamic Aggregation (MSDA) module. To improve matching efficiency, we design a novel Embedded PatchMacth scheme with random samples propagation, which involves end-to-end training with asymptotic linear computational cost to the input size. To further reduce computational cost and speed up convergence, we apply the coarse-to-fine strategy on Embedded PatchMacth constituting CFE-PatchMatch. To fully leverage reference information across multiple scales and enhance robustness to scale misalignment, we develop the MSDA module consisting of Dynamic Aggregation and Multi-Scale Aggregation. The Dynamic Aggregation corrects minor scale misalignment by dynamically aggregating features, and the Multi-Scale Aggregation brings robustness to large scale misalignment by fusing multi-scale information. Experimental results show that the proposed AMSA achieves superior performance over state-of-the-art approaches on both quantitative and qualitative evaluations.

Контрольная группа на про-тяжении всего эксперимента ежедневно находилась в течение 30 минут 2 раза в день в затравочной камере при от-сутствии табачного дыма. Животные опытной группы находились в равных условиях при ежедневном 30-минутном воздействии табачного дыма в затравочной камере 2 раза в день. Исследование полученных биосубстратов (легочная ткань, печень, костная ткань, плацента, гомогенат тканей плодов) проводилось на ИСП-АЭС и ИСП-МС. Выявлено, что в легочной ткани наблюдалось достоверное снижение содержания хрома (на 60%), йода (на 35%), кобальта (на 36%), марганца (на 50%) и увеличение токсичных элементов - мышьяка (на 37,5%), свинца (на 55%) и кадмия (на 46%). В печеночной ткани концентрации меди и железа снизились на 7% и 41,5%, соответственно; отмечалось увеличение стронция (на 11,9 %). В костной ткани наблюдалось уменьшение количества никеля (на 59%), цинка (на 45 %), кремния (на 25,8%) и увеличение олова, алюминия, свинца (на 69,1%, 42,6%, 31,5%, соответственно). В образцах плаценты самок-крыс обнаружено увеличение кадмия (на 79,8%) и свинца (на 38,7%). В организме плода было зафиксировано активное накопление целого ряда химических элементов: марганца (на 11,2%), цинка (на 15 %), селена (на 34,2%), ванадия (на 64%), бора (на 54 %), хрома (на 75%), йода (на 78,8%), алюминия (на 54%), кадмия (на 77%) и свинца (на 88,1%). Суммируя полученные результаты, можно предположить значительное негативное влияние пассивного табакокурения на обмен микроэлементов и токсичных элементов в системе «мать-плацента-плод».

description: We investigate star formation and dust heating in the compact FIR bright sources detected in the Herschel maps of M83. We use the source extraction code GETSOURCES to detect and extract sources in the FIR, as well as their photometry in the MIR and Hα. By performing infrared SED fitting and applying an Hα based star formation rate (SFR) calibration, we derive the dust masses and temperatures, SFRs, gas masses and star formation efficiencies (SFEs). The detected sources lie exclusively on the spiral arms and represent giant molecular associations (GMAs), with gas masses and sizes of 10^6-10^8 solar masses and 200-300 pc, respectively. The inferred parameters show little to no radial dependence and there is only a weak correlation between the SFRs and gas masses, which suggests that more massive clouds are less efficient at forming stars. Dust heating is mainly due to local star formation. However, although the sources are not optically thick, the total intrinsic young stellar population luminosity can almost completely account for the dust luminosity. This suggests that other radiation sources contribute to the dust heating as well and approximately compensate for the unabsorbed fraction of UV light.

description: Анализируются данные исследования влияния непрерывного образования на когнитивную сохранность личности в пожилом возрасте. Цель работы – изучение гибкости познавательного контроля, как один из показателей когнитивной сохранности. В исследовании принимали участие исследовании принимали участие 116 человек в возрасте от 60 до 84 лет. Каждый их них провел в системе формального образования от 8 до 36 лет. Среди респондентов были те, кто в течение жизни получил до четырех разных высших образований. Установлено, что регрессионная модель взаимосвязи длительность учения и гибкостью-ригидностью познавательного контроля отражает нелинейный характер изменений изучаемых переменных. Модель позволяет сделать вывод, что для лиц, потративших на формальное обучение мало лет (до 10) наблюдается явно выраженная ригидность познавательного контроля. По мере увеличения длительности учения ригидность познавательного контроля снижается, он становится более гибким. После 18 лет учения познавательный контроль продолжает оставаться гибким, без статистически значимой тенденции к дальнейшему изменению. Выявлена статистически значимая связь между длительность учения и гибкостью познавательного контроля. Длительное формальное образование – образование длиною в жизнь способствует сохранению гибкости мышления. Оно позволяет сохранять ясность и гибкость собственного мышления, обеспечивая тем самым спокойное, успешное старение, с полной сохранностью когнитивных функций. Проведенное исследование показало, что нет связи между возрастом респондентов и длительностью учения, между возрастом и гибкостью познавательного контроля. При этом наблюдается статистически значимая связь между длительностью учения и гибкостью познавательного контроля, что длительное формальное образование – образование длиною в жизнь способствует сохранению гибкости мышления. Поэтому, если возникает вопрос: «Зачем надо учиться всю жизнь?», то может быть очень простой ответ. Длительное, непрерывное образование позволяет не только легко адаптироваться к постоянно и стремительно изменяющимся социально-экономическим условиям жизни, но и сохранять ясность и гибкость собственного мышления, обеспечивая тем самым спокойное, успешное старение, с полной сохранностью когнитивных функций.

A collision model for DNS with ellipsoidal particles in viscous fluid

description: The article proposes an algorithm to model the collision between arbitrary ellipsoids in viscous fluid. It is composed of several steps, each improving upon the standard procedure employed in the current literature. First, an efficient contact detection algorithm is presented. Then, the semi-implicit Immersed Boundary Method of Tschisgale et al. (2018) is enhanced by the collision forces using the hard-sphere approach, so that the resulting model accounts for fluid forces throughout the entire collision process. Additionally, a new lubrication model is proposed that applies a constant lubrication force in the region where hydrodynamic forces are not resolved by the spatial grid. The new collision model is validated against benchmark test cases of particle wall collisions with excellent agreement. Furthermore, the collision of an ellipsoidal particle with a wall is investigated. The normal restitution coefficient in the case of ellipsoidal particles does not solely depend upon the Stokes number as in the case of spherical particles but is also a function of its shape, and the orientation before the collision. Using the new model, the effect of these parameters on the rebound trajectory is studied. It is found that the maximum normal restitution coefficient decreases significantly as the flatness of the particle increases. Also, the coefficient of restitution depends on the particle orientation, a tendency increasing with particle flatness. >>>>>>>>>>>>>>> Note, that the distance algorithm described in the paper is subject of a Corrigendum: https://www.sciencedirect.com/science/article/pii/S0301932222000313/pdfft?md5=1c1b8e790efdc6785c47297d89906fe6&pid=1-s2.0-S0301932222000313-main.pdf <<<<<<<<<<<<<<

description: Постановка проблемы. В работе исследовали влияние пептида IX, структурного фрагмента МСР-1, ускоряющего и усиливающего воспаление в острые сроки после ишемии-реперфузии, на работоспособность сердца через 72 ч и 28 сут после инфаркта миокарда у крыс.
Экспериментальные методы. Инфаркт миокарда моделировали перевязкой левой коронарной артерии, пептид IX вводили внутрисердечной инъекцией в момент операции, контрольной группе крыс вводили эквивалентный объем фи-зиологического раствора. Через 2,5 ч проводили реперфузию. Параметры гемодинамики оценивали через 72 ч и
28 сут после операции: частота сердечных сокращений, среднее артериальное давление, систолическое и диастолическое давление в левом желудочке сердца, индексы сократимости и расслабления миокарда в покое и в ответ на введение добутамина. Исследовали изменение регуляции работы сердца со стороны вегетативной нервной системы в покое и в ответ на воздействие холодом до операции и на фоне введения пептида через 24 ч, 72 ч и 28 сут после ишемии-реперфузии.
Результаты, практическое применение и новые задачи. Пептид IX обладал кардиопротекторным эффектом в острые сроки после операции: в ответ на введение добутамина усиливались реакции ЧСС, сократимость миокарда как в целом, так и непосредственно не затронутого ишемией, частично восстанавливалась функция расслабления. В отставленный период после операции различия между инфарктным контролем и группой с пептидом стирались. Таким образом, ускорение воспаления при ишемии-реперфузии за счет воздействия на моноциты и макрофаги демонстрирует ранний кардиопротекторный эффект. Для разработки концепции регулируемого воспаления при инфаркте миокарда требуются дальнейшие исследования.
