description: A low-noise X-band microstrip hybrid VCO has been designed and realised using a 2 x 50 µm GaN-on-SiC pseudo-morphic HEMT as the active device. The transistor has been manufactured by TIGER and features a gate-length of 0.15 µm, an fT of 22 GHz, a break-down voltage of 42 Volts and an Idss close to 1 A/mm. The VCO has been assembled with standard SMD reflow and chip-on-board technology on Rogers 4003 substrate material. The circuit is biased at +15 Volts and 38 mA and has a measured tuning range from 8.1 to 10.6 GHz, an output power level of +19 dBm and an average phase-noise level of -114 dBc/Hz @ 1 MHz offset.

description: This paper reports on the design of a cascode GaN HEMT distributed power amplifier demonstrating significant improvement of the best power performances reported to date. The active device is a 8x50µm AlGaN/GaN HEMT grown on siSiC. The distributed power amplifier integrates 4 cascode cells capacitively coupled to the gate line for power optimization. The active part made of the 4 cascode cells is implanted on a GaN-based wafer while the distributed passive part made of the interconnection lines is implanted on an AlN substrate. Finally, the GaN-based wafer integrating the active part is flip-chipped onto the AlN substrate via electrical and mechanical bumps. The flip-chip integrated circuit demonstrates a mean gain of 10dB and input/output matching lower than –10dB over the 4-18GHz bandwidth. At an input power of 29dBm (1db comp.), power simulations exhibit a mean output power of 37.6dBm with a standard deviation of 0.3dB, a power gain of 8.6dB and 16% of PAE over the band. At an input power of 31dBm (2dB comp.), the distributed amplifier achieves a mean output power of 38.6dBm, a power gain of 7.6dB and 18% of PAE.

description: Die Diagnose Prostatakarzinom wurde im Jahr 2018 allein in Europa 450.000 Mal gestellt. Diese Tumorentität ist sehr häufig und wächst langsam, sodass ein Eingreifen auch in späteren Phasen durchaus kurativ erfolgen kann. Umso wichtiger ist es Ansatzpunkten, die sich im Bereich der kurativen Forschung in diesem Gebiet ergeben, nachzugehen. Auf Grund der bereits getätigten Forschungen und daraus entstandenen Empfehlungen und der Beeinflussbarkeit von außen durch diätetische Maßnahmen ist die Rolle der Fette in diesem Zusammenhang interessant. Ebenfalls wichtig und relativ neu sind die Mitochondrien als Angriffspunkte für Chemoprävention und Chemotherapie. Diese Arbeit sollte deshalb die Einflüsse von extern zugegebenen Fettsäuren auf die Proliferation von Prostatakrebszellen beurteilen und zwar im Zusammenhang mit der veränderten Zusammensetzung des Cardiolipins, das als Phospholipid fast ausschließlich in der inneren Mitochondrienmembran vorkommt. Es konnte gezeigt werden, dass die Zusammensetzung des Cardiolipins durch externe Fettsäuren variabel ist und auch eine veränderte metabolische Aktivität der Prostatakarzinomzellen aus einem unterschiedlichen Fettsäureangebot resultiert. Linol-, Arachidon-, Stearin- und Ölsäure haben eindeutig antiproliferative Effekte. Außerdem besteht eine positive Korrelation für die metabolische Aktivität der Zellen und den Gehalt an Palmitoleinsäure. Ob sich daraus konkrete Ernährungsempfehlungen ergeben können, sollte Gegenstand weiterer Forschungen in vivo sein.
Discriminating mass from normal breast tissue: a novel ranklet image representation for ROI encoding

description: A support vector machine (SVM) classifier is used to determine whether regions
of interest (ROIs) found on breast radiographic images contain mass or
normal tissue. Before being presented to SVM, ROIs are encoded by means
of a specific image representation. The coefficients resulting from the encoding
are then used as classification features. Pixel and wavelet image representations
have already been discussed in one of our previous works. A
novel orientation–selective, non–parametric and multi–resolution image representation
is developed and evaluated herein, namely a ranklet image representation.
From the digital database for screening mammography (DDSM)
collected by the University of South Florida, a database of ROIs is generated.
A total of 1000 ROIs containing diagnosed masses are extracted from
the DDSM benign and malignant cases, whereas 5000 ROIs containing normal
tissue are extracted from the DDSM normal cases. The area Az under
the receiver operating characteristic curve is adopted for performance evaluation.
By achieving Az values of 0.978 ± 0.003, experiments demonstrate
better classification results with respect to those reached by the previous image
representations. In particular, the improvement on the Az value over that
achieved by the wavelet image representations is statistically relevant with
two–tailed p–value < 0.0001.

description: Bei der Achondroplasie [OMIM: 100800] handelt es sich um eine genetisch bedingte Form einer Skelettdysplasie. Eine gestörte enchondrale Ossifikation infolge einer aktivierenden Mutation eines Fibroblastenwachstumsfaktor-Rezeptors (FGFR)-3 hat eine Extremitätenverkürzung, einen ausgeprägten disproportionierten Kleinwuchs und ein Missverhältnis von Hirn- und Gesichtsschädel zur Folge. Kennzeichnend sind die verkürzte Schädelbasis und eine Stenose des Foramen magnum. Nicht selten sind rezidivierende Infektionen des Nasen-Rachenraums und bleibende Hörstörungen, auch Schlafapnoe und der plötzliche Kindstod wurden beschrieben. Kontrovers wird die Indikation zur operativen Erweiterung des Foramen magnum mit dem Ziel der sekundären Prävention der beschriebenen Komplikationen diskutiert. Während Empfehlungen einer Konsensuskonferenz von Zentren in den USA klinisch-neurologische Zeichen als ausreichend ansehen, empfehlen europäische Zentren (Großbritannien, Schweden, Deutschland) ein Screening mittels MRT des kraniozervikalen Übergangs. Für diese Studie werden verschiedene Hirnstrukturen bei Kindern mit und ohne Achondroplasie vermessen und gegenübergestellt, um eine objektivierbare OP-Indikation zu stellen. Mittels einer speziellen Software (Dornheim Segmenter ® ) wurden verschiedene Volumina anhand von cMRT-Bildern analysiert. Ein vergrößerter III. Ventrikel bei Kindern mit Achondroplasie und ein gleich großer, tendenziell sogar leicht verkleinerter IV. Ventrikel, gegenüber der in der Literatur allgemein beschriebenen Ventrikulomegalie, wurden hierbei ermittelt. Der steilere Winkel des Tentorium und die mutmaßlich verkleinerte Schädelgrube konnten als achondroplasiespezifische Merkmale identifiziert werden. Die vorliegenden Daten können auch für die gegenwärtig durchgeführten medikamentösen Therapiestudien bei Kindern mit Achondroplasie einen sinnvollen Endpunkt darstellen. Auf der Basis des positiven Effektes auf das Längenwachstum der langen Röhrenknochen bei den Studienteilnehmern kann auch ein Einfluss auf das enchondrale Knochenwachstum der Schädelbasis vermutet werden.

description: We seek to understand the origin of radial migration in spiral galaxies by analyzing in detail the structure and evolution of an idealized, isolated galactic disk. To understand the redistribution of stars, we characterize the time-evolution of properties of spirals that spontaneously form in the disk. Our models unambiguously show that in such disks, single spirals are unlikely, but that a number of transient patterns may coexist in the disk. However, we also show that while spirals are transient in amplitude, at any given time the disk favors patterns of certain pattern speeds. Using several runs with different numerical parameters we show that the properties of spirals that occur spontaneously in the disk do not sensitively depend on resolution. The existence of multiple transient patterns has large implications for the orbits of stars in the disk, and we therefore examine the resonant scattering mechanisms that profoundly alter angular momenta of individual stars. We confirm that the corotation scattering mechanism described by Sellwood & Binney (2002) is responsible for the largest angular momentum changes in our simulations.

description: The spaces we inhabit can shape and influence the way in which we learn or reinforce information. Virtual reality (VR) is a technology that allows us to alter and create designed environments with great freedom over the visual, audio, and narrative elements. This freedom would benefit from further guidelines that detail approaches and implementations to best achieve desired information delivery goals. In this paper we present findings of a study that applies location-based memory strategies to VR environments, with the aim to aid word list recall without the subjects being required to apply any memory strategy themselves. Our findings suggest that VR may interfere with the incidental processing of multiple rooms and potential aid to recall as demonstrated in real world studies.

description: Eine Myositis ist selten. Daher orientiert sich die klinische Praxis an den verfügbaren Daten von Patientenregistern, publizierten Fallserien und Expertenmeinungen. Ziel dieser Arbeit war eine detaillierte retrospektive Auswertung aller Patienten mit Myositis einer Fachklinik für Rheumatologie. In der hier vorgestellten retrospektiven Studie wurden 32 Patienten eingeschlossen, 6 mit Polymyositis, 6 mit Dermatomyositis, 11 mit Overlap-Myositis, 6 mit Antisynthetase-Syndrom, 1 mit autoimmun-nekrotisierender Myopathie, 1 mit juveniler Dermatomyositis und 1 mit juvenilem Antisynthetase-Syndrom. Das Durchschnittsalter bei Erstmanifestation betrug 49 Jahre (weiblich: männlich 3,5:1). Die Zeitspanne zwischen der Erstmanifestation und der Diagnosestellung betrug 5 Monate und die Beobachtungszeit 23 Monate. 90 % der Patienten hatten eine manifeste Muskelbeteiligung im Sinne von Myalgien mit oder ohne Muskelschwäche. Zu den extramuskulären Organmanifestationen gehörten die Lungen- (56 %), Gelenk- (56 %), Haut- (50 %) und Herzbeteiligung (28 %) sowie Dysphagie (31 %) und Raynaud-Phänomen (46 %). Am häufigsten fand sich eine Lungenfibrose in der Patientengruppe mit Antisynthetase-Syndrom (n = 5; p = 0,03). Bei Patienten mit Overlap-Myositis war das Auftreten von ANAs (n = 11; p = 0,003), einem Raynaud-Phänomen (n = 10; p = 0,001), einer reduzierten Kapillardichte in der Kapillarmikroskopie (n = 10; p = 0,03) und einer Polyarthritis der Hand- und Fingergelenke (n = 6, p = 0,04) signifikant häufiger als bei anderen Myositiden. Patienten mit Overlap-Myositis wiesen eine bessere Funktionskapazität als Patienten mit Antisynthetase-Syndrom (FFbH %: 83,3 ± 13 vs. 59,2 ± 12,6; p = 0,02) und Patienten mit Dermatomyositis (83,3 ± 13 vs. 62 ± 16,1; p = 0,008) auf. Patienten mit Dermatomyositis hatten zu Beginn einen signifikant höheren Steroidbedarf als Patienten mit Antisynthetase-Syndrom (100 vs. 13,75 mg/d; p = 0,01) und Overlap-Myositis (100 vs. 40 mg/d; p = 0,03). Die am häufigsten verabreichten Medikamente waren Cyclophosphamid (53 %), Methotrexat (34 %) und Rituximab (28 %) und konnten die Kreatinkinase (unter MTX von 18,1 auf 2,6 µmol/ls; p = 0,009, unter CYC von 24,9 auf 4,1 µmol/ls, p = 0,005, unter RTX von 8,5 auf 1,4 µmol/ls; p = 0,04) und die Tagesdosis von Prednisolon (unter MTX von 27,5 auf II 1,25 mg/d; p = 0,005, unter CYC von 50 auf 10 mg/d; p = 0,001, unter RTX von 17,5 auf 6,2 mg/d; p = 0,04) signifikant senken. Diese Studie bestätigt die Heterogenität der verschiedenen Diagnosegruppen bei Myositis und die Wirksamkeit verschiedener therapeutischer Ansätze.

description: I investigate two versions of a differential Cournot oligopoly game with nonrenewable resource exploitation, in which each firm may either exploit its own private pool or exploit a common pool jointly with the rivals. Firms use a deterministic technology to invest in exploration activities. In both models, there emerges that (i) the individual exploration effort is higher when each firms has exclusive rights on a pool of its own, and (ii) depending on the assumptions on technology and demand, the aggregate exploration effort is either constant or increasing in the number of firms.

Interwoven legal traditions. The extent to which state based decision makers are engaging with indigenous legal traditions and the extent to which this is feasible : a celebration of an exceptional outcome
Creators: name: Johnston, Natalie
Publisher: name: University of British Columbia
Year: 2015

description: In recognition of Canada being a legally pluralist state, there is ample impetus from multiple players within the Canadian legal landscape for Indigenous legal traditions to be recognized, respected and considered as sources of legitimate legal authority. The need to be attentive to Aboriginal interests is becoming increasingly important in the context of government decision making regulating natural resources extraction that the constitutional duty to consult governs. However, state based decision makers must be attentive to the Indigenous legal traditions that comprise the legal systems that existed upon colonial settlement and which remain alive today. Taking the recent Caribou cases as a case study, I analyse the extent to which Dunne Za law was recognised and respected in successive administrative and judicial decision making. Several Dunne Za legal traditions were interwoven throughout the petitioners’ submissions which arguably incited the Caribou cases. Chief of these laws is the traditional seasonal round. I interpret substantive and procedural components to decision making pursuant to this land management regime for maintaining balance and order. Throughout the analysis I highlight cultural, legal and operational constraints to the ability of decision makers to consider Indigenous legal traditions. Chief of these legal impediments is the reasonableness standard of review pursuant to which decisions as to the adequacy of consultation are assessed. The Caribou cases exhibit varying degrees of respect for Dunne Za law. The Chief Justice’s inclusive balancing approach, which considers the legal traditions that were at play as legitimate law, contrasts that of the statutory decision maker and other appellate judge, which, inter alia, devalued the petitioners’ hunting right to an interest capable of being trumped by competing economic interests. On several levels, the Caribou cases are a positive result that ought to be celebrated. However, this case study is an exception among many battles over the duty to consult that are not won. While Indigenous law has a presence in state based decision making, considerable progress must occur in the extent of respect for and consideration of Indigenous legal traditions, before parity of influence exists with common law legal traditions in state based decision-making
Mapping of Human Atrial Fibrillation : Constraints of Dominant Frequency and Complex Fractionated Atrial Electrograms

description: Vorhofflimmern (VHF) ist eine der häufigsten Herzrhythmusstörungen, von der über 6,8 Millionen Menschen in Europa und den Vereinigten Staaten betroffen sind. Die medikamentöse Behandlung ist meist unzureichend, und mit steigender Belastung an Vorhofflimmern liefern derzeitige Ablationsverfahren nur unbefriedigende Ergebnisse. Dies ist auf inadäquate Ausführung der bestehenden Ablationsstrategien zurückzuführen und/oder deuted darauf hin, dass derzeitige Strategien unzureichend sind. Da die räumlich-zeitliche Komplexität von VHF eine große Anzahl von Elektroden erfordern würde um ein genaues Bild der gesamten Vorhoferregung zu erstellen, werden Ersatzparameter, wie dominante Frequenz (DF) und komplex fraktionierte atriale Elektrogramme (CFAE) verwendet, um kritische Bereiche zu identifizieren, die für die Aufrechterhaltung von VHF ausschlaggebend erscheinen. Allerdings haben auch diese Verfahren ihre Schwachstellen. Die folgende Reihe von Studien ist darauf ausgerichtet, die Grenzen des Mapping von DF und CFAE mit heutigen Methoden zu erforschen. Außerdem untersuchen wir die fundamentalen Komponenten der räumlichen Auflösung von Elektroden43, sowie deren Einfluss auf die Messwerte von Frequenz113 und Fraktionierung44. Ausserdem wird ein Computermodell vorgestellt, das für die Untersuchung der Erregungsausbreitung und des daraus resultierenden Potentialfeldes entwickelt wurde. Dieses Modell wird dann in den folgenden Studien angewendet.

Ergänzt wurde die Analyse durch eine Befragung von Pflegepersonal und ärztlichem Personal zur Pfadeinführung. Die Analyse der Patienten mit einer laparoskopischen Cholezystektomie mit und ohne Pfad konnte die Effektivität der Pfadeinführung für diesen Eingriff für eine Reduktion der Parameter stationäre Verweildauer und Anzahl der Laborparameter und der damit verbunden Laborkosten je Fall signifikant nachweisen. Das Potential des Behandlungspfades ist bislang jedoch noch nicht ausgeschöpft, da in 37% noch Abweichungen von der geplanten Verweildauer vorliegen. Diese sind in der Mehrzahl nicht durch Komplikationen ausgelöst, sondern organisatorisch, durch eine Aufnahme am Tag vor der Operation zur Durchführung einer laut Leitlinie notwendigen Gastroskopie, bedingt. Die Reduzierung der Laborkosten pro Fall war ebenfalls signifikant durch die Pfadeinführung. Auch hier haben wir weiteres Potential nachgewiesen, da die Pfadabweichung hier sogar 81% betrug. Von Seiten der Pflege wird die Pfadeinführung durchweg sehr positiv betrachtet. Die Pflege wünscht sich auch expliziert die Einführung weiterer Pfade. Die Ärzte erkennen die Vorteile des Pfades durchaus, möchten aber mehrheitlich keine weiteren Pfade etablieren.

We show that the interplay between disorder and inter-site interactions leads to rich phase diagrams. A uniform disorder leads to a Haldane-insulator phase with finite parity order, whereas the density-wave phase becomes a Bose-glass at very weak disorder. For quasi-disorder, the Haldane insulator connects with a gapped generalized incommesurate density wave without an intermediate critical region.

description: Older adults, which are affected by neurological diseases such as dementia, often suffer from cognitive and motor deficits, and, therefore, require special care and therapy. However, especially during times of a global pandemic, they are a vulnerable highrisk group that has to be kept safe, which limits their possibilities to perform cognitive or motor training, or visit places outside their homes. We developed and evaluated a motor-cognitive exergame using a human-centered design approach, in which the older adults can virtually visit known places in their city of residence in omni-directional 3D-videos using immersive virtual reality (VR) technologies. The player's goal is to take pictures of famous landmarks with a tracked wearable that replicates a physical camera. We evaluated the game during a nine weeks user study with ten older adults with mild forms of dementia in a between-subject design: (i) five players experienced the game twice a week for 15-25 minutes, and (ii) five participants in a control group, who did not play the game. The results suggest that the overall well-being of players improved and that their game performance increased. Cognitive and physical tests indicate that the test group experiencing the game improved more than the control group. All players had positive attitudes towards the game and enjoyed the welcome change.

Comparison of data on Mutation Frequencies of Mice Caused by Radiation - Low Dose Model -

description: We propose LD(Low Dose) model, the extension of LDM model which was proposed in the previous paper [Y. Manabe et al.: J. Phys. Soc. Jpn. 81 (2012) 104004] to estimate biological damage caused by irradiation. LD model takes account of all the considerable effects including cell death effect as well as proliferation, apoptosis, repair. As a typical example of estimation, we apply LD model to the experiment of mutation frequency on the responses induced by the exposure to low levels of ionizing radiation. The most famous and extensive experiments are those summarized by Russell and Kelly [Russell, W. L. & Kelly, E. M: Proc. Natl Acad. Sci. USA 79 (1982) 539-541], which are known as 'Mega-mouse project'. This provides us with important information of the frequencies of transmitted specific-locus mutations induced in mouse spermatogonia stem-cells. It is found that the numerical results of the mutation frequency of mice are in reasonable agreement with the experimental data: the LD model reproduces the total dose and dose rate dependence of data reasonably. In order to see such dose-rate dependence more explicitly, we introduce the dose-rate effectiveness factor (DREF). This represents a sort of preventable effects such as repair, apoptosis and death of broken cells, which are to be competitive with proliferation effect of broken cells induced by irradiation.

description: Die Zielsetzung dieser wissenschaftlichen Arbeit war es, die Belastungen und Beanspruchungen von Angehörigen von Patienten mit akutem Lungenversagen auf Intensivstation zu explorieren und anhand eines Belastungs-Beanspruchungs-Modells als theoretischer Grundlage zu analysieren. Zur Datenerhebung wurden semi-standardisierte qualitative Interviews durchgeführt. 35 Familien wurden während ihres Besuchs auf der Intensivstation zur Teilnahme eingeladen. Es nahmen 17 Angehörige (im Alter von 26 – 71 Jahren, 9 davon Frauen) teil. Eine systematische Inhaltsanalyse wurde anhand des hier gewählten Belastungs-Beanspruchungs-Modells durchgeführt. Es konnten zahlreiche Belastungen identifiziert werden: Belastungen während der Besuche, Belastungen, die zu Hause auftreten und Belastungen durch die Organisation der Besuche. Diese Belastungen wurden von den Teilnehmern sehr einheitlich beschrieben. Dennoch variierte die Beanspruchung, die sich aus diesen Belastungen ergab. Zusammengefasst stellt diese Studie die zahlreichen Belastungen und Beanspruchungen von Angehörigen von Patienten mit ARDS dar. Einige Belastungen sind dem lebensbedrohlichen Zustand des Familienmitglieds geschuldet, andere ergeben sich aus den Strukturen auf der Intensivstation und im Alltag der Teilnehmer und könnten modifiziert werden. Das Ausmaß an Beanspruchung, das Angehörige erleben, steht im Zusammenhang mit dem Einfluss moderierender Variablen wie sozialer Unterstützung und Bewältigungsstrategien.

However, there is a dearth of heterogeneity and randomness, which characterize the age-related conditions and are important aspects in human-like simulations. Towards this end, procedurally generated age-related deficits are simulated in Virtual Reality environments, giving the possibility to experience these deficits and their nuances in real time. Our work is drawing upon state-of-the-art featurebased approaches, such as foveated rendering and procedural noise, to provide realistic effects. A pilot assessment is conducted through a visual performance task, while eye-tracking data are recorded. The preliminary results provide a first evaluation of the simulation's effectiveness in inducing, in normal subjects, a visual behavior similar to that of real patients.

description: Socio-economic performance differs not only across countries but within countries too and can persist even after religion, language, and formal institutions are long shared. One interpretation of these disparities is that successful regions are characterized by higher levels of trust, and, more generally, of cooperation. Here we study a classic case of within-country disparities, the Italian North-South divide, to find out whether people exhibit geographically distinct abilities to cooperate independently of many other factors and whence these differences emerge. Through an experiment in four Italian cities, we study the behavior of a sample of the general population toward trust and contributions to the common good. We find that trust and contributions vary in unison, and diminish moving from North to South. This regional gap cannot be attributed to payoffs from cooperation or to institutions, formal or informal, that may vary across Italy, as the experimental methodology silences their impact.
The gap is also independent of risk and other-regarding preferences which we measure experimentally, suggesting that the lower ability to cooperate we find in the South is not due to individual \moral" flaws. The gap could originate from emergent collective properties, such as different social norms and the expectations they engender. The absence of convergence in behavior during the last 150 years, since Italy was unified, further suggests that these norms can persist overtime. Using a millennium-long dataset, we explore whether the quality of past political institutions and the frequency of wars could explain the emergence of these differences in norms.

Cooperative firms and the crisis: evidence from some Italian mixed oligopolies

description: We investigate how cooperative firms reacted to the current crisis. This allows us to compare the behavior of cooperative and conventional firms facing exogenous shifts in demand. After a short survey of a stream of theoretical literature, we analyze a large group of Italian production cooperatives in the periods 2003-2010 and 1994-2011 and we contrast co-ops behavior with the overall trend in the industries in which they operate. Our sample’s evidence suggests that the cooperative’s behavior has a stabilizing effect on employment with respect to shocks in output demand. Unlike profit-maximizers, cooperative firms seem to be adjusting pay more than employment when facing shocks. Production co-ops look better equipped than their profit-maximizing counterparts in tackling the long recession also because they have been very cautious in their profit policies over time. Unlike conventional firms, they have significantly increased their own equity during “good” years instead of distributing large dividends to their members.

description: In this work, we consider the hedging error due to discrete trading in models with jumps. Extending an approach developed by Fukasawa [In Stochastic Analysis with Financial Applications (2011) 331-346 Birkhäuser/Springer Basel AG] for continuous processes, we propose a framework enabling us to (asymptotically) optimize the discretization times. More precisely, a discretization rule is said to be optimal if for a given cost function, no strategy has (asymptotically, for large cost) a lower mean square discretization error for a smaller cost. We focus on discretization rules based on hitting times and give explicit expressions for the optimal rules within this class.

description: Das Kälteschock Y-box binding Protein 1 partizipiert in der Tumorzelltransformation und vermittelt invasives Zellwachstum. Es ist unbekannt ob sich eine Autoimmunantwort gegen tumorös verändertes humanes YB-1 mit posttranslationalen Proteinmodifikationen oder Prozessierungen entwickelt. Es wurde eine systematische Analyse bezüglich einer Autoantikörperformation gegen Konformations- sowie lineare Epitope des Proteins durchgeführt. Rekombinante Volllängen- und gekürzte Proteine aus prokaryoten und eukaryoten Zellen wurden generiert. Die Charakterisierung offenbarte eine spontane Proteinspaltung, vornehmlich im prokaryoten Protein. Autoantikörper gegen prokaryotes, aber nicht eukaryotes YB-1 Protein wurden sowohl in den gesunden Kontrollprobanden als auch Tumorpatienten detektiert. Eine Kartierung von immunogenen Konformationsepitopen wurde mit gekürzten aus prokaryoten abgeleiteten humanen GST-YB-1 Proteinen durchgeführt und lieferte verschiedene Residuen im N- und C-terminalen Proteinabschnitt. Die Verwendung eines Peptid-Arrays, mit sich konsekutiv überlappenden Oligopeptiden mit jeweils 15 Aminosäuren Länge, zeigte 6 unterschiedliche antigene Regionen in Tumorpatienten, jedoch mit geringerem Ausmaß in den Kontrollprobanden. Schließlich wurde ein Proteinspaltungsansatz mit rekombinantem pro- und eukaryotem humanen YB-1 Protein durchgeführt. Es entstand ein unterschiedliches Spaltungsmuster, das sich verzögert mit den Seren von Tumorpatienten zeigte. Zusammenfassend entwickelt sich eine spezifische Autoimmunantwort gegen humanes YB-1 Protein in Tumoropatienten mit Autoantikörper, die gegen lineare - und Konformationsepitope gerichtet sind.

description: Differently from Atkinson and Morelli (2011) who detect no clear link between increases in income inequality and systemic banking crises, we show that a large majority of crises occurred between 1982 and 2008 have been preceded by persistently high levels of income inequality. Such association is robust when considering Gini values for incomes after-tax as well as before-tax and transfers. Moreover, we investigate the pattern of income inequality 
levels before and after a group of banking crises and the relative levels of income inequality in a large sample of OECD countries that did not experience banking crises between 1980 and 2010.

description: Virtual Reality (VR) enables new ways of learning by providing an interactive environment to learn through failure and by allowing new interaction methods engaging the users' bodies. Literature from productive failure and embodied cognition shows that these two aspects are particularly important for mathematics education. However, very little research has been looking into how to input mathematical expressions in VR. This gap impairs the learning process as it prevents the learners from connecting the VR mathematical objects with their formal representations. In this paper, we bridge this gap by presenting two interaction techniques for mathematics input in VR: a Keyboard-like method and a Drag-and-drop method. We report the results of our quantitative user study in terms of usability, ease of learning, low overhead, task load, and motion sickness.

The reduction of plankton biomass induced by mesoscale stirring: a modeling study in the Benguela upwelling

description: Recent studies, both based on remote sensed data and coupled models, showed a reduction of biological productivity due to vigorous horizontal stirring in upwelling areas. In order to better understand this phenomenon, we consider a system of oceanic flow from the Benguela area coupled with a simple biogeochemical model of Nutrient-Phyto-Zooplankton (NPZ) type. For the flow three different surface velocity fields are considered: one derived from satellite altimetry data, and the other two from a regional numerical model at two different spatial resolutions. We compute horizontal particle dispersion in terms of Lyapunov Exponents, and analyzed their correlations with phytoplankton concentrations. Our modelling approach confirms that in the south Benguela there is a reduction of biological activity when stirring is increased. Two-dimensional offshore advection and latitudinal difference in Primary Production, also mediated by the flow, seem to be the dominant processes involved. We estimate that mesoscale processes are responsible for 30 to 50% of the offshore fluxes of biological tracers. In the northern area, other factors not taken into account in our simulation are influencing the ecosystem. We suggest explanations for these results in the context of studies performed in other eastern boundary upwelling areas.
PROTECT : Erhebung des IST-Zustandes und Maßnahmen zur Quantitätssteigerung der Impfraten von Soldaten/innen der Bundeswehr

description: Einleitung: Impfungen gehören zu den wirksamsten präventivmedizinischen Maßnahmen. Neben den Standardimpfungen bestehen risikoadaptiert Indikationen für weitere Impfungen. In der deutschen Zivilbevölkerung und den Streitkräften anderer Länder zeigen sich Impflücken. Da zu Bundeswehrsoldaten/innen bisher keine Daten existieren, sollten die Impfraten und die Wirksamkeit eines Remindersystems in dieser Studie getestet werden. Methode: Es erfolgte die querschnittliche Erhebung der Impfraten von Rekruten/innen aus drei Quartalen im Jahr 2016. Ergänzend wurde in einer zwölfmonatigen randomisiert-kontrollierten Kohortenstudie untersucht, ob die Impfraten von aktiven Soldaten/innen mittels eines EDV-basierten Remindersystems gesteigert werden können. Ergebnisse: Bei den 247 Rekruten/innen zeigten sich Impfraten zwischen 2,0% gegen FSME und 75,3% gegen Masern. In der Kohortenstudie mit 506 Probanden/innen besaßen zu Studienbeginn 26,2/31,3% den geforderten Impfschutz. Am niedrigsten fielen die Impfraten von Influenza (50,5/49,1%) aus. Die höchsten Impfraten konnten für MMR (94,3/97,8%) identifiziert werden. Es kam im Studienverlauf in beiden Gruppen zu einem hochsignifikanten Anstieg der Impfraten (p < 0,001). Diskussion: Die Ergebnisse offenbaren ausgeprägte Impflücken bei Rekruten/innen und aktiven Bundeswehrsoldaten/innen. Diese konnten im Rahmen der Kohortenstudie signifikant reduziert werden. Jedoch kam es durch die Kommunikation der Gruppen zu einem Bias in der Datenbasis. Dennoch scheint ein EDV-gestütztes Remindersystem ein wirksames (Teil)-Instrument zum Erreichen der Impfziele zu sein.
