description: Developed logical reasoning is a necessary background for successful work as a lawyer, economist, man-ager, scientist; this is reflected in the standards of higher education in Ukraine. This is also a sign of universal and professional well-educated specialist, who is able to solve complex specialized issues and practical prob-lems in his own professional activity. Such activity involves possession of a certain logical arsenal: methods of analysis and synthesis, abstraction and generalization, ability to prove and disprove, to draw the right conclu-sions, to make reasonable and rational decisions. In connection with all before mentioned, there arises a prob-lem of finding ways to developing logical thinking of specialists in various fields, taking into account the his-torical connection of Logic with Mathematics. The theoretical and empirical research methods were applied to achieve the goal and solve the tasks of the research: scientific study of scholarly papers, analysis of educational and methodological literature, ped-agogical observations of the learning process of students. This paper clarifies the role and application of Logic as a science in Mathematics. It is proved on the ex-ample of binary relations, that predicate calculus gives an explicit insight into a general and abstract ideas and relations in Mathematics. This paper explains the connection between mathematical logic and other math-ematical disciplines; establishes the ways of implementation of logical laws in other sciences through teaching mathematical disciplines. Mathematical logic is essentially a formal logic that uses mathematics-based methods, in regard to this the so-called «mathematization» of knowledge is essentially «logical» knowledge. Therefore, the formation of the logical culture of a competitive specialist can achieve by studying various disciplines of Mathematics, or using a system of non-standard logical problems.

description: In this paper we give a bound to the number of conjugacy classes of maximal subgroups of any almost simple group whose socle is a classical group of Lie type. The bound is $2n^{5.2}+n\log_2\log_2 q$, where $n$ is the dimension of the classical socle and $q$ is the size of the defining field. To obtain the bound, we first bound the number of projective cross-characteristic representations of simple groups of Lie type as a function of the representation degree. These bounds are computed for different families of groups separately. In the computation, we use information on class numbers, minimal character degrees and gaps between character degrees.

description: Photopische multifokale visuell evozierte Potentiale (mfVEPP) sind ein etabliertes Verfahren zur objektiven Gesichtsfeldbestimmung beim Tagsehen (Herbik et al. 2014). Vollständig unerforscht sind skotopische mfVEPs (mfVEPS) zur Untersuchung des Nachtsehens. Ziel dieser Arbeit war die Entwicklung eines Verfahrens zur Messung skotopischer mfVEPs und der Nachweis von Charakteristiken des skotopischen Sehens, wie Zentralskotom und Latenzverlängerung. Für 9 Normalprobanden wurden „pattern-reversal“ mfVEPs für photopische und skotopische Bedingungen bestimmt (Gesichtsfeld 25° Radius). MfVEPP wurden mit einem regulären zentralen Fixationskreuz gemessen. Zum Ausschluss von Fixationsartefakten wurden (1) mfVEPS+ mit und (2) mfVEPS- ohne zusätzliche Fixationshilfe gemessen. Zwischen mfVEPP und mfVEPS wurden Latenzverschiebungen bestimmt und die Antwortgrößen exzentrizitätsabhängig quantitativ verglichen (Hood und Greenstein 2003). Im Vergleich zum mfVEPP waren mfVEPS+ und mfVEPS- um 101 ms sowie 97 ms verzögert. Für beide mfVEPS lagen die zentralen Antworten unter der Rauschgrenze und waren für die größte Exzentrizität reduziert. Die Gesichtsfeldabdeckung für den parazentralen Bereich von mfVEPS+ und mfVEPS- lag bei 76% und 65% [4°–9°], bzw. bei 79% und 66% [9°–16°]. Die Realisierbarkeit von mfVEPS wurde damit belegt und stellt folglich eine objektive, ortsaufgelöste Untersuchung des skotopischen Sehens zur Anwendung bei Patienten mit Nachtsehstörungen in Aussicht.

description: With an increasing number of spaceflights, it is crucial that we understand the changes that occur to our cells in space. I was interested in testing the effects of real (r-) and simulated (s-) microgravity (μg) on human breast cancer cells with the objective of investigating cytoskeletal alterations, focal adhesion molecules, extracellular matrix proteins, inflammatory cytokines and the potential mechanism of spheroid formation during microgravity. Besides microgravity, astronauts are subjected to other factors during space travel, including vibration, hypergravity and cosmic radiation. Moreover, vibrations occur during parabolic flights. To evaluate whether vibration has any beneficial impact on chondrocytes, I examined the effect of low-frequency vibration on human chondrocytes. Microgravity is known to exert a negative impact on chondrocytes and vibration could be the countermeasure to prevent such a negative impact. This thesis evaluated the impact of a 14-day-exposure of MCF-7 breast cancer cells to a random positioning machine (RPM). The cells exposed to the RPM divided into adherent and multicellular spheroids. A proteomics analysis examined the difference between adherent, spheroid and 1g control cells. The analysis revealed a reduction in E-cadherin in spheroids. This finding was confirmed by measuring the messenger RNA (mRNA) expression and protein content. There is a relation between E-cadherin regulation and spheroid formation. Furthermore, I performed live-cell imaging of transfected MCF-7 cells with a spinning-disc fluorescence microscopy analysis system (FLUMIAS) microscope during a sounding rocket mission. The cells exhibited a rearrangement of F-actin and tubulin. Moreover, I detected filopodia- and lamellipodia-like structures in the F-actin cytoskeleton shortly after the beginning of the microgravity phase. I also investigated the effect of microgravity on MCF-7 cells during a parabolic flight campaign (PFC). The cells manifested elevated KRT8, RDX, TIMP1 and CXCL8 mRNA, while VCL was downregulated. Furthermore, E-cadherin protein was significantly downregulated. These changes indicate a transformation of the MCF-7 cells into a more invasive cell type. In another study, I evaluated the effect of microgravity on the triple negative breast cancer cell line MDA-MB-231 during a PFC. The parabolic flight induced alterations in cell adhesion molecules, findings that are in agreement with previous data from other cell lines. Finally, I evaluated the impact of low-frequency vibration on human chondrocytes. There were no morphological changes, cytoskeletal alterations or apoptotic cells. Moreover, there was an upregulation of ANXA1, PXN and VCL mRNA and downregulation of ANXA2. Thus, I concluded that there is a beneficial effect of low-frequency vibration on human chondrocytes.

description: This paper deals with the concepts of persistence diagram and matching distance. These are two of the main ingredients of Topological Persistence, which has proven to be a promising framework for shape comparison. Persistence diagrams are descriptors providing a signature of the shapes under study, while the matching distance is a metric to compare them. One drawback in the application of these tools is the computational cost for the evaluation of the matching distance. The aim of the present paper is to introduce a new framework for the approximation of the
matching distance, which does not affect the reliability of the entire approach in comparing shapes, and extremely reduces the computational cost. This is shown through experiments on 3D-models.
The Rise and Fall of Redundancy in Decoherence and Quantum Darwinism

description: A state selected at random from the Hilbert space of a many-body system is overwhelmingly likely to exhibit highly non-classical correlations. For these typical states, half of the environment must be measured by an observer to determine the state of a given subsystem. The objectivity of classical reality-the fact that multiple observers can agree on the state of a subsystem after measuring just a small fraction of its environment-implies that the correlations found in nature between macroscopic systems and their environments are very exceptional. Building on previous studies of quantum Darwinism showing that highly redundant branching states are produced ubiquitously during pure decoherence, we examine conditions needed for the creation of branching states and study their demise through many-body interactions. We show that even constrained dynamics can suppress redundancy to the values typical of random states on relaxation timescales, and prove that these results hold exactly in the thermodynamic limit.

description: Sequential tunneling behavior of p-n resonant tunneling diode with four-period InP/InGaAs superlattice is demonstrated. Theoretical calculation shows three split quantized energies in the four-period InP (50Å)/InGaAs (25Å) superlattice structure. For the increase of more negative differential resistance (NDR) routes, high-field domain is formed in the superlattice under sufficiently large operation biases. Experimentally, an interesting six-route NDR characteristic, resulting from the form of split miniband structures and the extension of high-field domain in the InP/InGaAs superlattice, is observed at room temperature.

description: The combination of pre-emergence and post-emergence use of the studied drugs had a greater phytotoxic effect on the main weed species in soybean crops. Thus, cereal weeds were destroyed by 100%, Amaranthus retroflexus by 93%, and Chenopodium album by 94%. It should be noted in the areas where the composition was applied Frontier® Optima emulsion concentrate + Corum liquid concentrate + surfactant Metholate + Quantum Molybdenum Chelate phytotoxic effect on weeds increased, and soybean plants later grew and de-veloped better. Weed control rates for soybean weeds were 94-100% compared to control plots during the soy-bean harvest period. Yield of soybean seeds, where herbicides were applied in comparison with the control was on average: when using the herbicide Frontier®Optima e.c., 1,0 l/hа – 2,09 t/hа, Corum l.c., 1,5 l/ha + surfac-tant Metholate, 1,0 l/ha – in accordance 2,57 t/hа., and when applying Frontier® Optima e.c. + Corum l.c. + surfactant Metholate – 2,78 t/hа.

description: Extremely high potential barrier height and gate turn-on voltage of a novel GaAs field-effect transistor with n+/p+/n+/p+/n double camel-like gate structure are demonstrated. The maximum electric field and potential barrier height of the double camel-like gate are substantially enhanced by the addition of another n+/p+layers in gate region, as compared with the conventional n+/p+/n single camel-like gate. For a 1 x 100 m2 device, a potential barrier height up to 2.741 V is obtained. Experimentally, a high gate turn-on voltage up to + 4.9 V is achieved because two reverse-biased junctions of the double camel-like gate absorb part of positive gate voltage. In addition, the transistor action shows a maximum saturation current of 730 mA/mm and an extrinsic transconductance of 166 mS/mm.

description: We study a self-consistent solution of the semi-classical Einstein equation including the back reaction from the Hawking radiation. Our geometry is constructed by connecting flat space and the outgoing Vaidya metric at the locus of the shock wave. In order to prove that this is the self-consistent solution, we first show that the Weyl anomaly is canceled if we take the effects of the fluctuations of the metric into account. We further demonstrate that the Hawking radiation occurs even if the geometry has no horizon. Then, the energy-momentum tensor is found to be consistent with the semi-classical Einstein equation. Since our geometry has neither horizon nor singularity, all matters inside the black hole finally come back to infinity. Therefore, no information is lost by the black hole evaporation. Furthermore, we take into account the gray-body factor. We construct a stationary solution for a black hole in the heat bath and estimate the entropy. The entropy-area law is reproduced by the volume integration of the entropy density over the inside of the horizon, and the black hole can be treated as an ordinary thermodynamic object.

description: The hyperelliptic Torelli group is the subgroup of the mapping class group consisting of elements that act trivially on the homology of the surface and that also commute with some fixed hyperelliptic involution. The authors and Putman proved that this group is generated by Dehn twists about separating curves fixed by the hyperelliptic involution. In this paper, we introduce an algorithmic approach to factoring a wide class of elements of the hyperelliptic Torelli group into such Dehn twists, and apply our methods to several basic elements.

description: Hintergrund: Zerebrale Arteriosklerose stellt eine häufige Ursache ischämischer Schlaganfälle sowie einen Risikofaktor für die Genese intrakranieller Aneurysmen dar. Intravaskuläre bildgebende Verfahren wie der intravaskuläre Ultraschall (IVUS) und die optische Kohärenztomographie (OCT) bieten die Möglichkeit einer hochauflösenden Gefäßwanddarstellung, besitzen aktuell jedoch keine Zulassung für den intrazerebralen Einsatz. Ziel dieser Dissertationsarbeit ist es, die Anwendbarkeit intravaskulärer Verfahren zur Darstellung und Vermessung zerebraler Arteriosklerose und Aneurysmen ex vivo zu prüfen. Material und Methoden: 17 post mortem entnommene Circuli arteriosus Willisii wurden einheitlich mittels intravaskulären Kathetern vermessen und histologisch aufgearbeitet. Anschließend erfolgte eine Korrelation der intravaskulären mit den histologischen Schnittbildern sowie eine statistische Analyse der Daten. Ergebnisse: Die bildgebenden Verfahren IVUS und OCT ergaben eine im Vergleich zur Histologie verlängerte Messstrecke. Es konnte eine statistisch signifikante Abweichung zwischen den intravaskulären und den histologisch ermittelten Messstrecken für die Gefäßstellen „dünnste Stelle“, „unauffällige Gefäßwand“ und „Durchmesser“, jedoch nicht bei der Vermessung von Plaques ermittelt werden. Fibröse Plaques stellten sich in der OCT hyperintens mit dorsaler Abschwächung dar. Im IVUS zeigten sie eine gleiche Echogenität wie die unauffällige Gefäßwand ohne distale Abschwächung. Kalzifikationen erschienen in der OCT hypointens mit dorsaler Intensitätsminderung und im IVUS echoreich mit dorsalem Schallschatten. Cholesterineinlagerungen zeigten sich in der OCT hyperintens mit starker dorsaler Intensitätsminderung und im IVUS echoreich mit geringer Schallabschwächung. Insgesamt konnten drei rupturierte und zwei unrupturierte zerebrale Aneurysmen untersucht werden. Im OCT gelang eine genaue Beurteilung von eingelagerten Plaques im Aneurysma. Im IVUS war im Vergleich zur OCT die vollständige Darstellung des Aneurysmadurchmessers, jedoch ohne detaillierte Beurteilung der Wandbeschaffenheit möglich. Beide Methoden wiesen jedoch noch Einschränkungen in der Bildgebung und Beurteilung auf. Schlussfolgerung: Der IVUS und die OCT sind zur Plaquecharakterisierung und Vermessung der Plaquedicke geeignet. In der Darstellung der Aneurysmawand zur Abschätzung der Rupturgefahr zeigen sich Limitationen in IVUS und OCT.

description: The present paper reports on the implementation of electromechanical bias networks to be employed in an automated experimental set-up for the low frequency noise characterization of bipolar transistors. The obtained bias networks allowed to improve the automatization degree of the experimental set-up, reducing therefore the time and the efforts for the systematic characterization necessary for the identification of non-linear low frequency noise models. The electromechanical bias networks were successfully applied to the systematic characterization at wafer level of microwave GaInP/GaAs heterojunction bipolar transistors.

description: Die vorliegende wissenschaftliche Arbeit beschäftigt sich mit dem Einfluss eines methanolischen Extraktes von Ficus platyphylla (FP) auf die konditionierte Vermeidungsreaktion und die Körperkerntemperatur. Dafür wurde der Effekt von FP auf die lokomotorische Aktivität von weiblichen C57BL/6J Mäusen quantifiziert, um ausgewählte Dosen FP hinsichtlich ihres Effektes auf die Acquisition, die Konsolidierung und die Abrufbarkeit der bedingten Reaktion in der Shuttle-Box, die als two-way active avoidance klassifiziert wird, zu untersuchen. Alle entwickelten Neuroleptika weisen eine selektive Unterdrückung der konditionierten Vermeidungsreaktion auf, weshalb diesem Test eine hohe prädiktive Validität für die Testung neuer potenzieller Neuroleptika zugesprochen wird. Zusätzlich wurde FP an männlichen CD-1 Mäusen in einem Object Recognition Test geprüft, um seine prädiktive Validität einschätzen zu können. Anschließend wurde der Einfluss von Amphetamin und FP auf die Körperkerntemperatur überprüft in simultaner Applikation. Die Ergebnisse des Shuttle-Box Versuches zeigten keinen Einfluss von FP auf die Acquisition und die Konsolidierung, jedoch eine signifikante Beeinträchtigung der Abrufbarkeit der konditionierten Reaktion. Bei dem Object Recognition Test scheint die prädiktive Validität eingeschränkt zu sein. Die simultane Applikation von Amphetamin und FP zeigte eine Aufhebung der Hypothermie, wodurch eine dopaminerge Regulation der von FP induzierten Hypothermie wahrscheinlich wird. Die Ergebnisse bestätigen die Neuroleptika-ähnliche Wirkung von FP, vermutlich über die Modulation der Aktivität von dopaminergen Neuronen.

A packaged commerciallyavailablehigh power MESFET device (CREE CRF24010)is adoptedfor the model development.The extracted bias-dependent elementsof the small signal model as well as the measured DC data are mathematically described by small modification of Angelov’s formulation. Dispersion between DC and RF characteristics of the drain current is also observed and interpreted.The new model is capable to predict small signal as well as large signal performance accurately. A single stage ultra broadband 5 Wpoweramplifierhas been developed to verify the derived model.A good agreement has beenobtained between simulated and measured results.

description: Utilizing operational dynamic modeling [Phys. Rev. Lett. 109, 190403 (2012); arXiv:1105.4014], we demonstrate that any finite-dimensional representation of quantum and classical dynamics violates the Ehrenfest theorems. Other peculiarities are also revealed, including the nonexistence of the free particle and ambiguity in defining potential forces. Non-Hermitian mechanics is shown to have the same problems. This work compromises a popular belief that finite-dimensional mechanics is a straightforward discretization of the corresponding infinite-dimensional formulation.

Die inhärente Prognoserelevanz von Fernmetastasen begründet je nach Tumorentität den Bedarf und die Applikation von lokalen Therapieverfahren variabler Radikalität.

Lokale Ablationen wie die iBT offerieren den Patienten eine weniger invasive Therapieoption als das bei manchen Tumorentitäten teilweise als „Goldstandard“ etablierte lokale Therapieverfahren der chirurgischen Resektion. Die vorliegende Arbeit beschäftigt sich mit der Effektivität der iBT bei der Behandlung von Metastasen duktaler Adenokarzinome des Pankreas, Adenokarzinom des Magens sowie von Gastrointestinalen Stroma-Tumoren. Die Patienten aus den jeweiligen Studienkollektiven waren vor iBT progredient unter Systemtherapie oder unter „Chemopause“. Die iBT kam daher als Salvage Therapie zum Einsatz. Die behandelten Metastasen waren überwiegend hepatisch, jedoch auch peritoneal und vereinzelt an anderen Lokalisationen und wurden als chirurgisch unresektabel eingestuft oder die Resektion vom Patienten abgelehnt. Die Ergebnisse der drei retrospektiven, einarmigen Studien suggerieren einen Überlebensvorteil für die Patienten durch die Anwendung der iBT bei den untersuchten Tumorentitäten.

description: In der pädiatrischen Endokrinologie wird die Röntgenaufnahme der Hand zur Bestimmung des Knochenalters und Feststellung von Skelettreifestörungen genutzt. Zudem ist anhand des Knochenalters eine Prognose über die zu erwartende Erwachsenengröße möglich. Die Knochenalterbestimmungen werden über die visuelle Bestimmungsmethode nach Greulich und Pyle („Atlasmethode“) sowie die Methode nach Tanner und Whitehouse („Einzelknochenmethode) vorgenommen. Das Softwareprogramm BoneXpert, von der dänischen Firma Visiana 2008 entwickelt, bietet eine neue diagnostische Möglichkeit zur Software gestützten Bestimmung des Knochenalters aus planaren Röntgenbildern der linken Hand. In der vorliegenden Dissertation wurde retrospektiv ein pseudonymisiertes Patientenkollektiv (n= 202) mit unterschiedlichen Krankheitsbildern (Diabetes mellitus, Phenylketonurie, Ulrich-Turner-Syndrom und SHOX-Dysplasie), sowie ein heterogenes Kollektiv von 444 Kindern, die sukzessive in der endokrinologischen Sprechstunde wegen Wachstumsstörungen vorgestellt wurden, ausgewertet. Für diese Auswertung der Daten wurde das Votum der lokalen Ethikkommission eingeholt. Die visuell und softwaregestützt ermittelten Knochenalter zeigten eine hohe Übereinstimmung. Das automatisierte BoneXpert Verfahren stellt eine valide Untersuchungsmethode zur Knochenalterbestimmung im klinischen Alltag dar. Der Einsatzbereich der BoneXpert Software zur sicheren Bestimmung des Knochenalters konnte bestätigt werden. Es zeigten sich keine signifikanten Unterschiede der Ergebnisse der Knochenreifebestimmung. Der Vergleich von Lebensalter und Knochenreife zeigt sowohl mit der visuellen als auch mit der automatisierten Methode, in allen untersuchten Patientenkollektiven eine Gesamtabweichung von 3,3-6,2 Jahren, unabhängig vom Alter und Geschlecht. Keines der untersuchten Verfahren ist daher geeignet, bei unbekanntem Lebensalter eine hinreichend genaue Altersschätzung vorzunehmen. Die prospektive Erwachsenengröße zeigt im Vergleich mit der tatsächlich erreichten Körpergröße im Erwachsenenalter bei 23 Kindern im Mittel eine Abweichung von 4,3 cm. In Einzelfällen wurden auch deutlich größere Abweichungen beobachtet. 1

description: In this paper, a broadband mixer has been developed using 0.15-m pHEMT technology.  This singly balanced mixer was realized by using Schottky diodes.  A modified Marchand balun was employed at the LO port and matched to the diodes directly to achieve wideband performance and compact size.  This diode mixer achieves conversion loss of better than 10 dB from 46 to 78 GHz with LO power of 12.5 dBm, and the chip size is only 0.57 mm x 0.52 mm.  Compared with previously reported MMIC mixers in millimeter-wave frequencies, this circuit has the smallest chip size with competitive performance and wide bandwidth.

description: We propose a Bayesian model for mixed ordinal and continuous multivariate data to evaluate a latent spatial Gaussian process. Our proposed model can be used in many contexts where mixed continuous and discrete multivariate responses are observed in an effort to quantify an unobservable continuous measurement. In our example, the latent, or unobservable measurement is wetland condition. While predicted values of the latent wetland condition variable produced by the model at each location do not hold any intrinsic value, the relative magnitudes of the wetland condition values are of interest. In addition, by including point-referenced covariates in the model, we are able to make predictions at new locations for both the latent random variable and the multivariate response. Lastly, the model produces ranks of the multivariate responses in relation to the unobserved latent random field. This is an important result as it allows us to determine which response variables are most closely correlated with the latent variable. Our approach offers an alternative to traditional indices based on best professional judgment that are frequently used in ecology. We apply our model to assess wetland condition in the North Platte and Rio Grande River Basins in Colorado. The model facilitates a comparison of wetland condition at multiple locations and ranks the importance of in-field measurements.

description: In der Literatur wird beschrieben, der Hausarzt sei die erste Anlaufstelle für Betroffene einer Demenzerkrankung. Ausschluss von Differentialdiagnosen, cerebrale Bildgebung und Screeningtestverfahren werden als diagnostische Mittel genannt. In dieser Studie wurde in einem qualitativen Teil untersucht, wie Hausärzte mit Demenzerkrankung umgehen. In einem quantitativen Teil wurde das diagnostische Vorgehen, dabei insbesondere die Einstellung zu Screeningtestverfahren und die Schwierigkeiten evaluiert und das Antwortverhalten auf Verzerrung im Sinne der sozialen Erwünschtheit geprüft. Das Abweichen von Verhaltensroutinen veranlasst den Hausarzt zu einer Demenzdiagnostik. Screeningtestverfahren spielten vor allem in der quantitativen Studie eine große Rolle. Als Schwierigkeiten wurden vor allem mangelnde Zeit, unzureichende Vergütung und der therapeutische Nihilismus genannt. Ein Antwortverhalten im Sinne der sozialen Erwünschtheit konnte nicht nachgewiesen werden. Jüngere Hausärzte führen mehr Diagnostik selbst durch und leiten eine Behandlung ein.

description: This paper presents the design and realization of a new fully integrated multifunction circuit which is of great interest for all applications that need low cost phase locked microwave oscillators. The realization described here is in X band, but the design can be easily extrapolated up to millimeter frequencies. Experimental results are presented about all the MMIC's functions. A low cost package, also extrapolable up to higher frequencies is described.

description: Schwangerschaft stellt ein komplexes Zusammenspiel verschiedenster Immunzellen dar um die Entwicklung des Fötus als semiallogenes Transplantat zu gewährleisten. Ziel dieser Arbeit war die Rolle Interleukin 10 produzierender regulatorischer B-Zellen in der Frühschwangerschaft des Menschen zur evaluieren um Rückschlüsse auf Schwangerschaftspathologien ziehen zu können. Es konnte mittels Durchflusszytometrie gezeigt werden, dass die Anzahl an CD19 + CD24 hi CD27 hi regulatorischen B-Zellen bei normal schwangeren Frauen im 1.Trimester erhöht war und zum 3.Trimester abfiel, im Gegensatz zu Patientinnen, die an einer Fehlgeburt litten, die durchgehend niedrige Anteile an regulatorischen B- Zellen hatten. In vitro waren CD19 + B-Zellen normal schwangerer Frauen in der Lage die TNFα Expression CD4 + T-Zellen zu reduzieren, womit ein immunsuppressiver Wirkmechanismus der B-Zellen in der Schwangerschaft nachgewiesen werden konnte. Zudem konnte gezeigt werden, dass Serum schwangerer Frauen zu einer Induktion der IL10 Expression CD19 + B-Zellen führt, sodass lösliche Faktoren wie Hormone möglicherweise die Entwicklung regulatorischer B-Zellen in der Schwangerschaft unterstützen. Insgesamt zeigt sich, dass B-Zellen und ihre regulatorische Unterform am komplexen Zusammenspiel des Immunsystems im Kontext der Schwangerschaft teilhaben und Störungen in diesem System zur Entstehung von Schwangerschaftspathologien beitragen.

description: The concept of a linear transistor, called d-FET, was developed. The device conduction path is formed by a two-dimensional electron gas, and has a simpler construction in comparison to heterostructure  devices,  such as  the High Electron Mobility Transistor (HEMTS).  A computer program was developed so as to self-consistently simulate the electrical and physical characteristics under  the gate region.  By using this simulations, the semiconductor film to be grown by MOCVD was optimised.  The film showed a two-dimensional density of 1.1012 cm-2   and FWHM of only 3O A. The fabricated device characteristics were in good agreement with the simulated ones, with a transconduct once of 130 mS/mm. and cut-off frequency of 8 GHz. The promising features of this type of device are presented and analysed.

A Geometric Theory for Hypergraph Matching

Publisher: name: arXiv

Subjects: subject: Combinatorics (math.CO)

description: We develop a theory for the existence of perfect matchings in hypergraphs under quite general conditions. Informally speaking, the obstructions to perfect matchings are geometric, and are of two distinct types: 'space barriers' from convex geometry, and 'divisibility barriers' from arithmetic lattice-based constructions. To formulate precise results, we introduce the setting of simplicial complexes with minimum degree sequences, which is a generalisation of the usual minimum degree condition. We determine the essentially best possible minimum degree sequence for finding an almost perfect matching. Furthermore, our main result establishes the stability property: under the same degree assumption, if there is no perfect matching then there must be a space or divisibility barrier. This allows the use of the stability method in proving exact results. Besides recovering previous results, we apply our theory to the solution of two open problems on hypergraph packings: the minimum degree threshold for packing tetrahedra in 3-graphs, and Fischer's conjecture on a multipartite form of the Hajnal-Szemerédi Theorem. Here we prove the exact result for tetrahedra and the asymptotic result for Fischer's conjecture; since the exact result for the latter is technical we defer it to a subsequent paper.
