Nonlinear shear response of cantilever reinforced concrete shear walls with floor slabs
Creators: name: Mercer, Stephen Sterling
Publisher: name: University of British Columbia
Year: 2012

description: The nonlinear shear behaviour of cantilever reinforced concrete shear walls is complex and not fully understood. Design assumptions often oversimplify the wall response and can yield results which do not reflect the true response of the shear wall. One such assumption is analyzing the wall ignoring the effects from multiple floor slabs connected to the wall over its height. Floor slabs can provide a significant increase in wall shear capacity. This thesis examines the nonlinear shear response of walls, including the effect of floor slabs as a wall-slab system, through state-of-the-art nonlinear finite element analysis. Finite element slab models were developed to emulate the 3D slab effect within a 2D analysis environment: a high-end pseudo 3D model for in-depth slab analysis and a simple 2D slab layer model for typical wall analysis. The slab effects are explored through a parametric study varying the wall size, concrete strength, axial load, horizontal steel ratio and the slab dimensions parallel and perpendicular to the wall. The slabs were found to act like large external stirrups which provide additional tension capacity for the slab and limit shear cracking and failure. The slabs can significantly increase the shear capacity of lightly-reinforced walls. Using the developed slab models, the bounds of the slab effect were investigated by a parametric study with lightly to heavily-reinforced walls, with and without axial load, as well as varying the slab spacing. Within this study, the nonlinear response of isolated walls is compared to nonlinear uniformly-loaded membrane models. It is determined that although code-based shear capacity equations are fairly accurate, the membrane models can underestimate the shear stiffness and over predict the ductility. This study also reveals that tightly spaced slabs can increase up to 3 times the isolated wall capacity for walls with minimum horizontal steel, whereas there is little effect for walls with horizontal steel above 1%. Finally, methods were developed to predict the nonlinear shear stress-strain response of isolated walls and the peak shear capacity of wall-slab systems.

description: We use the tools of hybrid intranuclear-cascade/nuclear-de-excitation models to evaluate the sensitivity of several physical observables to the inclusion of a multifragmentation stage in the de-excitation chain and assess the need for a multifragmentation model in the quantitative description of p+56Fe and p+136Xe reactions at 1-GeV incident energy. We seek clear signatures of multifragmentation by comparing different state-of-the-art de-excitation models coupled with intranuclear-cascade models and by focusing on discriminating observables such as correlations and fragment longitudinal-velocity distributions. None of the considered observables can be unambiguously interpreted as a multifragmentation footprint. The experimental data are best described as originating from sequential binary decays. However, no de-excitation model can reproduce the experimental longitudinal-velocity distributions from 1-GeV p+136Xe.

description: In this paper, we present results from a Broadcast News story segmentation system developed for the SRI NIGHTINGALE system operating on English, Arabic and Mandarin news shows to provide input to subsequent question-answering processes. Using a rule-induction algorithm with automatically extracted acoustic and lexical features, we report success rates that are competitive with state-of-the-art systems on each input language. We further demonstrate that features useful for English and Mandarin are not discriminative for Arabic.

description: Black hole (BH) accretion flows and jets are qualitatively affected by the presence of ordered magnetic fields. We study fully three-dimensional global general relativistic magnetohydrodynamic (MHD) simulations of radially extended and thick (height $H$ to cylindrical radius $R$ ratio of $|H/R|\sim 0.2--1$) accretion flows around BHs with various dimensionless spins ($a/M$, with BH mass $M$) and with initially toroidally-dominated ($ϕ$-directed) and poloidally-dominated ($R-z$ directed) magnetic fields. Firstly, for toroidal field models and BHs with high enough $|a/M|$, coherent large-scale (i.e. $\gg H$) dipolar poloidal magnetic flux patches emerge, thread the BH, and generate transient relativistic jets. Secondly, for poloidal field models, poloidal magnetic flux readily accretes through the disk from large radii and builds-up to a natural saturation point near the BH. For sufficiently high $|a/M|$ or low $|H/R|$ the polar magnetic field compresses the inflow into a geometrically thin highly non-axisymmetric "magnetically choked accretion flow" (MCAF) within which the standard linear magneto-rotational instability is suppressed. The condition of a highly-magnetized state over most of the horizon is optimal for the Blandford-Znajek mechanism that generates persistent relativistic jets with $\gtrsim 100$% efficiency for $|a/M|\gtrsim 0.9$. A magnetic Rayleigh-Taylor and Kelvin-Helmholtz unstable magnetospheric interface forms between the compressed inflow and bulging jet magnetosphere, which drives a new jet-disk quasi-periodic oscillation (JD-QPO) mechanism. The high-frequency QPO has spherical harmonic $|m|=1$ mode period of $τ\sim 70GM/c^3$ for $a/M\sim 0.9$ with coherence quality factors $Q\gtrsim 10$. [abridged]

description: In this paper, we describe a set of experiments that examine the correlation between energy and pitch accent. We tested the discriminative power of the energy component of frequency sub- bands with a variety of frequencies and bandwidths on read speech spoken by four native speakers of Standard American English, us- ing an analysis by classification approach. We found that the frequency region most robust to speaker differences is between 2 and 20 bark. Across all speakers, using only energy features we were able to predict pitch accent in read speech with accuracy of 81.9%.

description: The Arabic language is a collection of spoken dialects with important phonological, morphological, lexical, and syntactic differences, along with a standard written language, Modern Standard Arabic (MSA). Since the spoken dialects are not officially written, it is very costly to obtain adequate corpora to use for training dialect NLP tools such as parsers. In this paper, we address the problem of parsing transcribed spoken Levantine Arabic (LA). We do not assume the existence of any annotated LA corpus (except for development and testing), nor of a parallel corpus LA-MSA. Instead, we use explicit knowledge about the relation between LA and MSA.

title: Comparison of the strength of iceberg and other freshwater ice and the effect of temperature
Creators: name: Jones, S. J.
Publisher: name: National Research Council of Canada. Institute for Ocean Technology
Year: 2006

description: Based on literature results, the temperature of an iceberg around the Grand Banks of Newfoundland is shown to vary from -2°C at the surface to approximately -20°C at depth. This temperature variation affects the strength of the ice. The strength of iceberg ice is shown to be 1.7 times less than other freshwater ice at a strain-rate of 10-³s-¹, probably due to pre-existing cracks. Using an activation energy of 80kJ/mol., the uniaxial compressive strength of iceberg ice is shown to vary from 5 MPa at -2°C near the surface, to 8 MPa at -20°C, at 10-20m depth.

description: Einige Stämme von Mikroalgen weisen ein günstiges Aminosäureprofil auf und enthalten die Omega-3-Fettsäuren Eicosapentaensäure (EPA) und Docosahexaensäure (DHA). Basierend auf Satellitendaten wurde ein rechenbasierter Ansatz entwickelt, um die Mikroalgenkultivierung in einer Ökobilanz nach ISO Standard 14040/44 auszuwerten und mit Fischprodukten zu vergleichen – auf Basis des Brennwerts, sowie Gehalts an Protein und Omega-3-Fettsäuren. Eine techno-ökonomische Analyse untersuchte die ökonomische Durchführbarkeit der Kultivierung von Mikroalgen. So wiesen Mikroalgen meistens geringere umweltschädliche Wirkungen auf als Fisch aus Aquakultur. Eine möglichst lange Kultivierungssaison war immer vorzuziehen, sowohl aus ökologischen als auch aus ökonomischen Gründen. Eine ganzjährige Kultivierung von Mikroalgen ist im feuchten Kontinentalklima nicht möglich. Dennoch stellen Mikroalgen eine umweltfreundliche und profitable Alternative zu Fischprodukten dar, die den Druck auf die Weltmeere abmildern können, und einen Beitrag zur Versorgung der Weltbevölkerung mit essentiellen Nährstoffen liefern können.
description: Some strains of microalgae have a favorable amino acid profile and may contain sufficient amounts of the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Based on satellite data, a computational approach was developed to evaluate microalgae cultivation in a life cycle assessment (LCA) according to ISO standard 14040/44 and compare it to fish products based on the content of nutritional energy, protein and omega-3 fatty acids. A techno-economic analysis investigated the economic feasibility of microalgae cultivation. The LCA analysis showed that microalgae, in most cases, have less harmful effects on the environment than fish from aquaculture. A longer cultivation season was always preferable, both for ecological and economic reasons. Year-round cultivation of microalgae is not feasible in the humid continental climate. Yet, microalgae represent an environmentally friendly and profitable alternative to fish products, which can reduce the pressure on the world's oceans and contribute to supplying the world population with essential nutrients.

description: We compute the analogue Hawking radiation for modes which posses a small wave vector perpendicular to the horizon. For low frequencies, the resulting mass term induces a total reflection. This generates an extra mode mixing that occurs in the supersonic region, which cancels out the infrared divergence of the near horizon spectrum. As a result, the amplitude of the undulation (0-frequency wave with macroscopic amplitude) emitted in white hole flows now saturates at the linear level, unlike what was recently found in the massless case. In addition, we point out that the mass introduces a new type of undulation which is produced in black hole flows, and which is well described in the hydrodynamical regime.

description: Chronische Nierenerkrankungen (CNE) können unbekannte Ursachen haben. Mögliche Ursache kann die Exposition mit Mykotoxinen, wie z.B. Ochratoxin A (OTA) sein. OTA kommt oftmals zusammen mit Citrinin (CIT) vor. Darum wurde getestet ob es einen Synergismus zwischen OTA und CIT gibt. Die Ergebnisse zeigen, dass nur die simultane Exposition zu Inflammation, EMT und Fibrose führt. Darüber hinaus hat die Hemmung der ERK1/2 und JNK1/2 Aktivität zu einer Verminderung der OTA Effekte geführt. Es konnte gezeigt werden, dass OTA und CIT, in Abhängigkeit von ERK1/2 und JNK1/2, synergistisch die Entstehung nephropathischer Prozesse begünstigen. Es ist bekannt, dass die Kommunikation von Epithelzellen und Fibroblasten, an der Entstehung von CNE beteiligt ist. Darum wurde die Notwendigkeit von zellulärer Kommunikation, für OTA-induzierte Nierenschäden getestet. Das wurde mit Hilfe einer Kokultur, mit Tubuluszellen und Fibroblasten, getestet. Die Ergebnisse zeigen, dass OTA nur unter Kokulturbedingungen zu EMT, Inflammation und Fibrose führt. Die OTA-induzierten Änderungen konnten durch Hemmung von miR-21, miR-200a, COX-2 und ERK1/2 verhindert werden.
description: Chronic kidney diseases (CKD) can have an unknown etiology. Causes can be mycotoxins, e.g. the nephrotoxic Ochratoxin A (OTA). OTA occurs often together with citrinin (CIT) in foodstuff. Thus, the hypothesis if OTA and CIT are acting synergistically regarding their nephropathic potential was tested. The results show that only simultaneously exposure with OTA and CIT led to inflammation, EMT and fibrosis. Furthermore, inhibition of the MAPK ERK 1/2 and JNK 1/2 reduced the OTA-induced effects. In conclusion, OTA and CIT act synergistically favoring nephropathic processes depending on ERK1/2 and JNK1/2. Furthermore, it is known that the communication between epithelial cells and surrounding fibroblasts can be, involved in the development of CKD. Thus, it was tested if intercellular communication is required for OTA-induced renal damage. This was investigated in a co-culture with proximal tubule cells and fibroblasts. The results showed that only under co-culture conditions OTA led to changes indicating EMT, inflammation and fibrosis. The OTA-induced changes were prevented by inhibition of miR-21, -200a, COX-2 or ERK1/2.

description: We demonstrate dispersion tailoring by coupling the even and the odd modes in a line-defect photonic crystal waveguide. Coupling is determined ab-initio using group theory analysis, rather than by trial and error optimisation of the design parameters. A family of dispersion curves is generated by controlling a single geometrical parameter. This concept is demonstrated experimentally on 1.5mm-long waveguides with very good agreement with theory.
Local Structure and Inference in Large Random Graphs

description: Modern social networks now contain on the order of 100 million to 1 billion active profiles. The graph structure of these networks contains an unprecedented amount of information about the social connectivity of the world; however, contemporary algorithms used to estimate random graph models from data are computationally intractable at this scale. To address this, we turn to the graphon random graph model. Graphons are suited to modeling data with a large number of nodes, and where exchangeability of the nodes can be assumed.Various estimation procedures for graphons exist in the literature. However, accurate estimation requires either an unbiased sample or some way to account for potential bias in the sampling scheme. We present a framework for working with small edge-induced samples of graphons. To account for the sampling bias, we first establish theory that describes the sampling distribution of these subgraphs. Building on this, we propose a procedure for undoing the sampling bias. This allows for estimation of whole-network structure from only an ego network. An interesting consequence of these results is that the mutual friend counts found on most social media platforms contain a great deal of information about the local community structure. Finally, we characterize the asymptotic behavior of a different network model, the Edge-Degeneracy exponential random graph model.

Phase identification and compositional studies of the ingots were performed by scanning electron microscopy, energy dispersive X-ray spectrometry, and X-ray powder diffraction. Transparent regions of the bar related with the formation of LiGd1-xLuxF4 solid solutions were found to be enlarged proportionally to the initial amount of Lu in the mixtures. Gd segregates to the end of the ingot.

Out-of-plane stability of reinforced masonry shear walls under seismic loading : cyclic uniaxial tests
Creators: name: Azimikor, Nazli
Publisher: name: University of British Columbia
Year: 2012

description: In recent years, widespread application of low-rise masonry construction, including post-disaster buildings like fire halls, has become limited in seismic regions of Canada. This is because the Canadian Masonry Design Standard (CSA S304.1-04) [Canadian Standard Association 2004] mandates stringent requirements on the design of ductile reinforced masonry (RM) shear walls, especially with regard to their height-to-thickness (h/t) ratios, which were restricted to ensure against out-of-plane instability. This failure mechanism has been observed in the end zones of reinforced concrete shear walls loaded in-plane in experimental research and in past earthquakes. However, there is a lack of similar evidence for RM shear walls; this is a motivation for the research program described in this thesis. The research consists of several major tasks. First, a review of the literature on previous experimental research studies on RM shear walls was conducted, followed by comprehensive investigation into the parameters affecting out-of-plane instability of RM shear walls,. Based on the results of this literature review, the first phase of the experimental program was designed with a focus on modeling the RM wall end zone and understanding the mechanism of lateral instability. Five full-scale specimens representing the wall end zones were constructed and subjected to reversed cyclic axial tension and compression until failure. The effect of varying h/t ratios of the plastic hinge zone, as well as level of axial tensile strain on the out-of-plane instability was examined. Based on the results of the experimental study, it was concluded that the level of applied tensile strain in the wall end zone is one of the critical factors governing its lateral instability. Therefore, the maximum tensile strain that may be imposed on a moderately ductile RM wall end-zone is determined based on a kinematic relationship between the axial strain and the out-of-plane displacement. A preliminary mechanic model has been proposed to predict the maximum tensile strain before instability takes place. The model can be incorporated into design provisions related to the thickness of shear walls of a given height. A comparison with the experimental results showed that the model offers conservative prediction of the maximum tensile strain.

description: X-ray observations of young Planetary Nebulæ (PNe) have revealed diffuse emission in extended regions around both H-rich and  H-deficient central stars. In order to also repro-duce physical properties of H-deficient objects, we have, at first, extended our time-dependent radiation-hydrodynamic models with heat conduction for such conditions. Here we present some of the important physical concepts, which determine how and when a hot wind-blown bubble forms. In this study we have had to consider the, largely unknown, evolution of the CSPN, the slow (AGB) wind, the fast hot-CSPN wind, and the chemical composition. The main conclusion of our work is that heat conduction is needed to explain X-ray properties of wind-blown bubbles also in H-deficient objects.

description: We studied the role of the tensor interaction in He isotopes systematically on the basis of the tensor-optimized shell model (TOSM). We use a bare nucleon-nucleon interaction AV8 obtained from nucleon-nucleon scattering data. The short-range correlation is treated in the unitary correlation operator method (UCOM). Using the TOSM+UCOM approach, we investigate the role of tensor interaction on each spectrum in He isotopes. It is found that the tensor interaction enhances the LS splitting energy observed in 5He, in which the p1/2 and p3/2 orbits play different roles on the tensor correlation. In {6,7,8}He, the low-lying states containing extra neutrons in the p3/2 orbit gain the tensor contribution. On the other hand, the excited states containing extra neutrons in the p1/2 orbit lose the tensor contribution due to the Pauli-blocking effect with the 2p2h states in the 4He core configuration.

Josephson-like spin current in junctions composed of antiferromagnets and ferromagnets

description: We study Josephson-like junctions formed by materials with antiferromagnetic (AF) order parameters. As an antiferromagnet, we consider a two-band material in which a spin density wave (SDW) arises. This could be Fe-based pnictides in the temperature interval ${T_{\text{c}}\leq T\leq T_{N}}$, where $T_{c}$ and $T_{N}$ are the critical temperatures for the superconducting and antiferromagnetic transitions, respectively. The spin current $j_{\text{Sp}}$ in AF/F/AF junctions with a ballistic ferromagnetic layer and in tunnel AF/I/AF junctions is calculated. It depends on the angle between the magnetization vectors in the AF leads in the same way as the Josephson current depends on the phase difference of the superconducting order parameters in S/I/S tunnel junctions. It turns out that in AF/F/AF junctions, two components of the SDW order parameter are induced in the F\nobreakdash-layer. One of them oscillates in space with a short period ${ξ_{\text{F,b}} \sim \hbar v/\mathcal{H}}$ while the other decays monotonously from the interfaces over a long distance of the order ${ξ_{\text{N,b}}=\hbar v/2πT}$ (where $v$, $\mathcal{H}$ and $T$ are the Fermi velocity, the exchange energy and the temperature, respectively; the subindex $\text{b}$ denotes the ballistic case). This is a clear analogy with the case of Josephson S/F/S junctions with a nonhomogeneous magnetization where short- and long\nobreakdash-range condensate components are induced in the F\nobreakdash-layer. However, in contrast to the charge Josephson current in S/F/S junctions, the spin current in AF/F/AF junctions is not constant in space, but oscillates in the ballistic F\nobreakdash-layer. We also calculate the dependence of $j_{\text{Sp}}$ on the deviation from the ideal nesting in the AF/I/AF junctions.

description: The Strange-tailed Tyrant Alectrurus risora (Aves: Tyrannidae) is an endemic species of southern South American grasslands that suffered a 90% reduction of its original distribution due to habitat transformation. This has led the species to be classified as globally Vulnerable. By the beginning of the last century, populations were partially migratory and moved south during the breeding season. Currently, the main breeding population inhabits the Ibera wetlands in the province of Corrientes, north-east Argentina, where it is resident all year round. There are two remaining small populations in the province of Formosa, north-east Argentina, and in southern Paraguay, which are separated from the main population by the Parana-Paraguay River and its continuous riverine forest habitat. The populations of Corrientes and Formosa are separated by 300 km and the grasslands between populations are non-continuous due to habitat transformation. We used mtDNA sequences and eight microsatellite loci to test if there were evidences of genetic isolation between Argentinean populations. We found no evidence of genetic structure between populations (Phi(ST) = 0.004, P = 0.32; Fst = 0.01, P = 0.06), which can be explained by either retained ancestral polymorphism or by dispersal between populations. We found no evidence for a recent demographic bottleneck in nuclear loci. Our results indicate that these populations could be managed as a single conservation unit on a regional scale. Conservation actions should be focused on preserving the remaining network of areas with natural grasslands to guarantee reproduction, dispersal and prevent further decline of populations.

Wir konnten zeigen, dass IQD5 in der Formmorphogenese von Blattpflasterzellen (PC) und der Zelluloseabscheidung an antiklinalen Zellwänden von PCs eine Rolle spielt. IQD5 interagiert auch mit CaM an MTs und liefert erste Hinweise auf wichtige Funktionen von Ca2+ bei der Regulation der PC-Morphogenese. Daher glauben wir, dass IQD5 als Regulator für die Koordination des Ca2+ Signalwegs, der MT-Organisation und der Zellwandbildung fungiert.
description: Calcium signalling plays an important role in regulation of plant growth and development. IQ67-Domain (IQD) proteins are one of the largest family of Calmodulin (CaM) binding proteins in plants, with 33 members in Arabidopsis thaliana, most of them are associated with microtubules (MT). Despite the large family size, functions of IQDs are largely elusive. To elucidate biological roles of IQD and their interacting Kinesin Light Chain-Related (KLCR) proteins, our study focused on the functional characterization of IQD-KLCR module using reverse genetics approach. We could demonstrate that IQD5 functions in leaf pavement cell (PC) shape morphogenesis and cellulose deposition at anticlinal cell walls of PCs. Also, IQD5 interacts with CaM at cortical MTs and provide first evidence for important roles of calcium in regulation of PC morphogenesis. Thus we suggest that IQD5 possibly might act as a hub for coordination of Ca2+ signalling, MT organization, and cell wall formation.

description: We study the production of the lightest neutralinos in the radiative process $e^+e^- \to \tildeχ^0_1 \tildeχ^0_1γ$ in low energy supersymmetric models for the International Linear Collider energies with longitudinally polarized electron and positron beams. For this purpose we consider the case of nonminimal supersymmetric standard model as well as the case of minimal supersymmetric standard model. At the first stage of a linear collider, with $\sqrt{s} =500$ GeV, the radiative production of the lightest neutralinos may be a viable channel to study supersymmetric partners of the Standard Model particles, especially if the other supersymmetric particles are too heavy to to be pair-produced. We consider in detail the effect of beam polarization on the production cross section. We compare and contrast the dependence of the signal cross section on the parameters of the neutralino sector of the nonminimal and minimal supersymmetric standard model when the electron and positron beams are longitudinally polarized. In order to assess the feasibility of experimentally observing the radiative neutralino production process, we consider the background to this process coming from the Standard Model process $e^+e^- \to ν\barνγ$ with longitudinally polarized electron and positron beams. We also consider the supersymmetric background to the radiative neutralino production process coming from the radiative production of the scalar partners of the neutrinos (sneutrinos) $e^+e^- \to \tildeν\tildeν^\ast γ$, with longitudinally polarized beams. This process can be a a background to the radiative neutralino production when the sneutrinos decay invisibly.

description: The pyramid evaluation effort for the 2006 Document Understanding Conference involved twenty-two sites on twenty document sets. Each pyramid content model (one per document set) was constructed from four human summaries. Peer systems were scored using the modified pyramid score introduced in DUC 2005. ANOVAs with score as the independent variable and nine factors yielded three significant factors: document set, peer, and content responsiveness. There were many more significant differences among peer systems in 2006 than for DUC 2005. We speculate this is due to a combination of improved systems and improvements in our evaluation procedures.

description: A proposal by Lüscher enables one to compute the scattering phases of elastic two-body systems from the energy levels of the lattice Hamiltonian in a finite volume. In this work we generalize the formalism to S--, P-- and D--wave meson and baryon resonances, and general total momenta. Employing nonvanishing momenta has several advantages, among them making a wider range of energy levels accessible on a single lattice volume and shifting the level crossing to smaller values of $m_πL$.

description: Successful Intelligent Tutoring Systems (ITSs) must be able to recognize when their students are asking a question. They must identify question form as well as function in order to respond appropriately. Our study examines whether intonational features, specifically, F0 height and rise range, are useful cues to student question type in a corpus of 643 American English questions. Results show a quantitative effect of both form and function. In addition, among clarification-seeking questions, we observed differences based on the type of clarification being sought. 1 Index Terms: intonation, questions, tutoring, dialog acts.
On the mean profiles of radio pulsars I: Theory of the propagation effects

description: We study the influence of the propagation effects on the mean profiles of radio pulsars using the Kravtsov-Orlov method of the wave propagation in the inhomogeneous media. This approach allows us firstly to include into consideration the transition from geometrical optics to vacuum propagation, the cyclotron absorption, and the wave refraction simultaneously. In addition, arbitrary non-dipole magnetic field configuration, drift motion of plasma particles, and their realistic energy distribution are taken into account. The one-to-one correspondence between the signs of circular polarization and position angle (p.a.) derivative along the profile for both ordinary and extraordinary waves is predicted. Using the numerical integration we now can model the main profiles of radio pulsars. It is shown that standard S-shape form of the p.a. swing can be realized for small enough pair production multiplicity and large enough bulk plasma Lorentz factor only. It is also shown that the value of p.a. maximum derivative, that is often used for determination the angle between magnetic dipole and rotation axis, depends on the plasma parameters and could differ from the rotation vector model (RVM) prediction.

description: Septische Erkrankungen stellen ein bedeutendes intensivmedizinisches Problem dar. Einer tendenziell steigendenden Inzidenz stehen eingeschränkte therapeutische Möglichkeiten gegenüber. In der Folge geht die Sepsis mit einer erheblichen Mortalität einher. Es besteht daher eine dringende Indikation die der Sepsis zu Grunde liegenden Pathomechanismen auf molekularer Ebene aufzudecken. Ein interessanter Ansatzpunkt ist die Sepsis-bedingt veränderte Expression von miRNAs. miRNAs fungieren als Regulatoren der Proteinbiosynthese und werden zum einen als potenzielle neue Sepsis-Biomarker und zum anderen als mögliche neue Therapeutika diskutiert. Voraussetzung hierfür ist die Kenntnis, welche miRNAs im Rahmen einer Sepsis zell- und gewebespezifisch verändert exprimiert werden. Die vorliegende Arbeit hatte zum Ziel, in Aorten septischer Mäuse sowie in pro-inflammatorisch exponierten Monozyten/Makrophagen und Endothelzellen mittels eines umfassenden zweifachen Screenings in Kombination mit einer ddPCR-basierten Validierung differenziell exprimierte miRNAs zu identifizieren.
description: Septic diseases represent a significant problem in intensive care medicine. The increasing incidence is combined with limited therapeutic options. As a result, sepsis is associated with considerable mortality. Therefore is an urgent indication to uncover the pathomechanisms underlying sepsis at the molecular level. An interesting starting point is the change in expression of miRNAs due to sepsis. miRNAs act as regulators of protein biosynthesis and are discussed on the one hand as potential new sepsis biomarkers and on the other hand as possible new therapeutic agents. A prerequisite for this is knowledge of which miRNAs are expressed in a cell and tissue-specific manner in the context of sepsis. The aim of the present work was to identify differentially expressed miRNAs in aortic septic mice as well as in pro-inflammatory exposed monocytes / macrophages and endothelial cells by means of a comprehensive twofold screening in combination with a ddPCR-based validation.

description: The ground state of the two-dimensional electron systems in Bernal bilayer and ABC-stacked multilayer graphenes in the presence of a strong magnetic field is investigated with the Hartree-Fock approximation. Phase diagrams of the systems are obtained, focusing on charge density wave states including states with vortices of valley pseudospins (called a Skyrme crystal). The single-electron states in these stacked graphenes are given by two-component wave functions. That of the first excited Landau level has the same component as the lowest Landau level of the ordinary two-dimensional electrons. Because of this localized wave functions, the Skyrme crystal has low energy in this first excited level up to four layers of graphene, when the inter-layer distance is assumed to be infinitesimal. At the same time, bubble crystals are suppressed, so the phase diagram is different from that of a single-layer graphene.

description: Email thread reassembly is the task of linking messages by parent-child relationships. In this paper, we present two approaches to address this problem. One exploits previously undocumented header information from the Microsoft Exchange Protocol. The other uses string similarity metrics and a heuristic algorithm to reassemble threads in the absence of header information. The pros and cons of both methods are discussed. The similarity matching method is evaluated using the Enron email corpus and found to perform well.
