description: We study analytically the dynamics and the micro-structural changes of a host medium caused by a driven tracer particle moving in a confined, quiescent molecular crowding environment. Imitating typical settings of active micro-rheology experiments, we consider here a minimal model comprising a geometrically confined lattice system -- a two-dimensional strip-like or a three-dimensional capillary-like -- populated by two types of hard-core particles with stochastic dynamics -- a tracer particle driven by a constant external force and bath particles moving completely at random. Resorting to a decoupling scheme, which permits us to go beyond the linear-response approximation (Stokes regime) for arbitrary densities of the lattice gas particles, we determine the force-velocity relation for the tracer particle and the stationary density profiles of the host medium particles around it. These results are validated a posteriori by extensive numerical simulations for a wide range of parameters. Our theoretical analysis reveals two striking features: a) We show that, under certain conditions, the terminal velocity of the driven tracer particle is a nonmonotonic function of the force, so that in some parameter range the differential mobility becomes negative, and b) the biased particle drives the whole system into a nonequilibrium steady-state with a stationary particle density profile past the tracer, which decays exponentially, in sharp contrast with the behavior observed for unbounded lattices, where an algebraic decay is known to take place.

description: Die Universität Konstanz deckt ihren Bedarf nach einem institutionellen Forschungsdatenrepositorium mit der von FIZ Karlsruhe angebotenen Lösung „RADAR Local“. Als Alternative zu einer Eigenentwicklung wurde das Datenrepositorium als hybrides Modell mit Repositorien-Software und Archivierung auf lokaler Infrastruktur implementiert. Dabei stellt FIZ Karlsruhe die etablierte Repositorien-Software RADAR zur Verfügung, wartet und betreibt sie aus der Ferne und passt sie nach Kundenwunsch an. Um die parallele Installation und Pflege der RADAR-Software auf mehreren lokalen Instanzen effizient bewältigen zu können, hat FIZ Karlsruhe vorab den Automatisierungsgrad der betroffenen Prozesse in der Software-Entwicklung, in der Systemkonfiguration und im Deployment erhöht. Dies wurde durch den Einsatz von Container-Virtualisierung wie Docker und Docker Swarm sowie mit Orchestrierungswerkzeugen wie Ansible erreicht. Der zeitliche Aufwand und der personelle Ressourcenbedarf reduzieren sich dadurch für die Universität Konstanz und als Ergebnis erhält sie ein gepflegtes Repositorium auf dem aktuellen Stand der Technik. Gleichzeitig erfordert diese Betriebsvariante eine intensive Auseinandersetzung mit dem jeweiligen Geschäftsmodell und den technischen Rahmenbedingungen des Anbieters, eine genaue Kostenkalkulation sowie möglicherweise Kompromisse oder Abstriche bei individuellen Wünschen.

description: We report the results from our analysis of a large set of archival data acquired with the X-ray telescope (XRT) onboard Swift, covering the sky region surrounding objects from the first Fermi Large Area Telescope (LAT) catalogue of high-energy sources (1FHL), which still lack an association. Of the 23 regions analysed, ten did not show any evidence of X-ray emission, but 13 were characterised by the presence of one or more objects emitting in the 0.3-10 keV band. Only in a couple of cases is the X-ray counterpart located outside the Fermi positional uncertainty, while in all other cases the associations found are compatible with the high-energy error ellipses. All counterparts we found have been studied in detail by means of a multi-waveband approach to evaluate their nature or class; in most cases, we have been able to propose a likely or possible association except for one Fermi source whose nature remains doubtful at the moment. The majority of the likely associations are extragalactic in nature, most probably blazars of the BL Lac type.

description: Sum-of-squares (SOS) methods have been shown to be very useful in computing polynomial Lyapunov functions for systems of reasonably small size. However for large scale systems it is necessary to use a scalable alternative using vector Lyapunov functions. Earlier works have shown that under certain conditions the stability of an interconnected system can be studied through suitable comparison equations. However finding such comparison equations can be non-trivial. In this work we propose an SOS based systematic procedure to directly compute the comparison equations for interconnected system with polynomial dynamics. With an example of interacting Van der Pol systems, we illustrate how this facilitates a scalable and parallel approach to stability analysis.

description: Three-dimensional confinement allows semiconductor quantum dots (QDs) to exhibit size-tunable electronic and optical properties that enable a wide range of opto-electronic applications from displays, solar cells and bio-medical imaging to single-electron devices. Additional modalities such as spin and valley properties can provide further degrees of freedom requisite for quantum information and spintronics. When seeking to combine these material features into QD structures, however, confinement can cause hybridization that inhibits the robustness of these emergent properties for insertion into quantum devices. Here, we show that a new class of laterally-confined materials, monolayer MoS$_2$ QDs, can be created through top-down nanopatterning of an atomically-thin two-dimensional semiconductor so that they exhibit the same valley polarization as in a continuous monolayer sheet. Semiconductor-compatible nanofabrication process allows for these low-dimensional materials to be integrated into complex systems, an important feature for advancing quantum information applications. The inherited bulk spin and valley properties, the size dependence of excitonic energies, and the ability to fabricate MoS$_2$ QDs using semiconductor-compatible processing suggest that monolayer semiconductor QDs have the potential to be multimodal building blocks of integrated quantum information and spintronics systems.

description: Lateral canthal lines or crow's feet lines (CFL) may be treated with onabotulinumtoxinA. We identified several key concepts important to understanding the use of onabotulinumtoxinA for treatment of moderate-to-severe CFL. To contextualize and integrate data on the recommended dose and injection patterns of onabotulinumtoxinA for treatment of CFL, we summarized data from pivotal clinical studies in the development of onabotulinumtoxinA for treatment of CFL. Data from key studies of onabotulinumtoxinA for CFL are presented. The efficacy and safety of onabotulinumtoxinA treatment of moderate-to-severe CFL were evaluated in 2 randomized, controlled phase 3 studies comprising 1362 patients. The 24U total dose of onabotulinumtoxinA used in these studies was based on a phase 2 dose-ranging trial. Two injection patterns were available to investigators; each involved 3 injection sites per side in the lateral orbicularis oculi muscle. A cross-sectional analysis of photographs from the phase 3 trials provided detailed information on the frequency of 4 distinct CFL patterns. In the primary efficacy analysis for each phase 3 trial, CFL responder rates were significantly greater with onabotulinumtoxinA vs placebo at day 30 ( P < .001). Eyelid edema (1%) was the only adverse event reported in ≥1% of patients receiving onabotulinumtoxinA, occurring more frequently with onabotulinumtoxinA than with placebo. The studies showed that onabotulinumtoxinA is effective and generally well-tolerated for CFL treatment. Additionally, 2 different injection patterns allow physicians to tailor treatment based on a patient's CFL pattern.

description: For two given $ω$-terms $α$ and $β$, the word problem for $ω$-terms over a variety $\boldsymbol{\mathrm{V}}$ asks whether $α=β$ in all monoids in $\boldsymbol{\mathrm{V}}$. We show that the word problem for $ω$-terms over each level of the Trotter-Weil Hierarchy is decidable. More precisely, for every fixed variety in the Trotter-Weil Hierarchy, our approach yields an algorithm in nondeterministic logarithmic space (NL). In addition, we provide deterministic polynomial time algorithms which are more efficient than straightforward translations of the NL-algorithms. As an application of our results, we show that separability by the so-called corners of the Trotter-Weil Hierarchy is witnessed by $ω$-terms (this property is also known as $ω$-reducibility). In particular, the separation problem for the corners of the Trotter-Weil Hierarchy is decidable.

description: BACKGROUND: Abdominoplasty, a commonly performed aesthetic procedure, is considered to have an increased risk of venous thromboembolism (VTE) events. At present, routine VTE chemoprophylaxis following abdominoplasty remains controversial.

OBJECTIVES: This study evaluates the authors' experience with rivaroxaban, an oral Factor Xa inhibitor, for VTE prophylaxis in abdominoplasty patients.

METHODS: A retrospective case series was conducted. All patients who underwent abdominoplasty and received rivaroxaban were included. The prophylactic dose was 10 mg daily for 7 days, beginning 12 hours postoperatively. Patient demographics, comorbidities, and type of surgery were recorded. The primary outcome measured was hematologic complication, including VTE, hematoma requiring operative evacuation, and need for blood transfusion.

RESULTS: From September 2012 until July 2014, 132 patients (122 women and 10 men) underwent abdominoplasty surgery and received rivaroxaban postoperatively. Mean patient age was 43.7 years, and mean body mass index was 27.1. One hundred twenty-five patients also underwent abdominal muscle plication. Eleven patients underwent a fleur de lis vertical skin resection component. One hundred patients underwent concomitant abdominal liposuction, while 79 patients also had back liposuction. Only 1 patient had a symptomatic VTE event. Three patients had a hematoma requiring operative evacuation, and all went on to heal without sequelae. Two patients received a blood transfusion for anemia during their course of rivaroxaban.

CONCLUSIONS: Oral rivaroxaban administration for chemoprophylaxis in abdominoplasty patients is safe, with low rates of symptomatic VTE and hematoma formation. The authors continue routine use of the medication for patients at increased risk for VTE events. LEVEL OF EVIDENCE 4: Risk.
Female chess players outperform expectations when playing men

description: "Stereotype threat" has been offered as a potential explanation of differential performance between men and women in some cognitive domains. Questions remain about the reliability and generality of the phenomenon. Previous studies have found that stereotype threat is activated in female chess players when they are matched against male players. I use data from over 5.5 million games of international tournament chess and find no evidence of a stereotype threat effect. In fact women players outperform expectations when playing men. Further analysis shows no influence of degree of challenge, nor of player age, nor of prevalence of female role models in national chess leagues on differences in performance when women play men versus when they play women. Though this analysis contradicts one specific mechanism of influence of gender stereotypes, the persistent differences between male and female players suggest that systematic factors do exist and remain to be uncovered.

description: Female sex workers (FSW) living with HIV in sub-Saharan Africa have poor engagement to HIV care and treatment. Understanding the HIV care and treatment engagement experiences of FSW has important implications for interventions to enhance care and treatment outcomes. We conducted a systematic review to examine the HIV care experiences and determinants of linkage and retention in care, antiretroviral therapy (ART) initiation, and ART adherence and viral suppression among FSW living with HIV in sub-Saharan Africa. The databases PubMed, Embase, Web of Science, SCOPUS, CINAHL, Global Health, Psycinfo, Sociological Abstracts, and Popline were searched for variations of search terms related to sex work and HIV care and treatment among sub-Saharan African populations. Ten peer-reviewed articles published between January 2000 and August 2015 met inclusion criteria and were included in this review. Despite expanded ART access, FSW in sub-Saharan Africa have sub-optimal HIV care and treatment engagement outcomes. Stigma, discrimination, poor nutrition, food insecurity, and substance use were commonly reported and associated with poor linkage to care, retention in care, and ART initiation. Included studies suggest that interventions with FSW should focus on multilevel barriers to engagement in HIV care and treatment and explore the involvement of social support from intimate male partners. Our results emphasise several critical points of intervention for FSW living with HIV, which are urgently needed to enhance linkage to HIV care, retention in care, and treatment initiation, particularly where the HIV prevalence among FSW is greatest.

description: Small to medium-scale data science experiments often rely on research software developed ad-hoc by individual scientists or small teams. Often there is no time to make the research software fast, reusable, and open access. The consequence is twofold. First, subsequent researchers must spend significant work hours building upon the proposed hypotheses or experimental framework. In the worst case, others cannot reproduce the experiment and reuse the findings for subsequent research. Second, suppose the ad-hoc research software fails during often long-running computational expensive experiments. In that case, the overall effort to iteratively improve the software and rerun the experiments creates significant time pressure on the researchers. We suggest making caching an integral part of the research software development process, even before the first line of code is written. This article outlines caching recommendations for developing research software in data science projects. Our recommendations provide a perspective to circumvent common problems such as propriety dependence, speed, etc. At the same time, caching contributes to the reproducibility of experiments in the open science workflow. Concerning the four guiding principles, i.e., Findability, Accessibility, Interoperability, and Reusability (FAIR), we foresee that including the proposed recommendation in a research software development will make the data related to that software FAIRer for both machines and humans. We exhibit the usefulness of some of the proposed recommendations on our recently completed research software project in mathematical information retrieval.

description: The Next-to-Minimal Supersymmetric extension of the Standard Model (NMSSM) with a Higgs boson of mass 125 GeV can be compatible with stop masses of order of the electroweak scale, thereby reducing the degree of fine-tuning necessary to achieve electroweak symmetry breaking. Moreover, in an attractive region of the NMSSM parameter space, corresponding to the "alignment limit" in which one of the neutral Higgs fields lies approximately in the same direction in field space as the doublet Higgs vacuum expectation value, the observed Higgs boson is predicted to have Standard-Model-like properties. We derive analytical expressions for the alignment conditions and show that they point toward a more natural region of parameter space for electroweak symmetry breaking, while allowing for perturbativity of the theory up to the Planck scale. Moreover, the alignment limit in the NMSSM leads to a well defined spectrum in the Higgs and Higgsino sectors, and yields a rich and interesting Higgs boson phenomenology that can be tested at the LHC. We discuss the most promising channels for discovery and present several benchmark points for further study.

description: Using a combination of the replica-exchange Monte Carlo algorithm and the multicanonical method, we investigate the influence of bending stiffness on the conformational phases of a bead-stick homopolymer model and present the pseudo-phase diagram for the complete range of semi-flexible polymers, from flexible to stiff. Although a simple model, we observe a rich variety of conformational phases, reminiscent of conformations observed for synthetic polymers or biopolymers. Changing the internal bending stiffness, the model exhibits different pseudo phases like bent, hairpin or toroidal. In particular, we find thermodynamically stable knots and transitions into these knotted phases with a clear phase coexistence, but almost no change in the mean total energy.

description: Given a polynomial \[ f(x)=a_0x^n+a_1x^{n-1}+\cdots +a_n \] with positive coefficients $a_k$, and a positive integer $M\leq n$, we define a(n infinite) generalized Hurwitz matrix $H_M(f):=(a_{Mj-i})_{i,j}$. We prove that the polynomial $f(z)$ does not vanish in the sector $$ \left\{z\in\mathbb{C}: |\arg (z)| < \fracπ{M}\right\} $$ whenever the matrix $H_M$ is totally nonnegative. This result generalizes the classical Hurwitz' Theorem on stable polynomials ($M=2$), the Aissen-Edrei-Schoenberg-Whitney theorem on polynomials with negative real roots ($M=1$), and the Cowling-Thron theorem ($M=n$). In this connection, we also develop a generalization of the classical Euclidean algorithm, of independent interest per se.

description: The project aims to gain new insights into how musicians discover and explore the affordances of Digital Musical Instruments (DMIs), with a specific focus on which aspects of DMIs are important in learning and developing skilful performance techniques. An underlying hypothesis that shapes the proposed research is that good musical instruments exhibit a high degree of alignment across a musician’s perception, action, and the instruments' gesture-sonic behaviours. The specific project objectives are: · develop a theoretical framework about the relationship between digital instruments and musicians’ perception-action skills that is both explanatory and practically useful. · develop a range of techniques, employing physical modelling methods and physical computing to prototype new instruments that reflect relevant features of the theoretical framework. · through two experimental studies, gain new data on and derive knowledge of how specifically designed variations in alignment in DMIs influence (1) the process of discovery of the dynamic properties of the instrument and (2) the acquisition of new skills and techniques.

description: This work aims to identify classes of DOI mistakes by analysing the open bibliographic metadata available in Crossref, highlighting which publishers were responsible for such mistakes and how many of these incorrect DOIs could be corrected through automatic processes. By using a list of invalid cited DOIs gathered by OpenCitations while processing the OpenCitations Index of Crossref open DOI-to-DOI citations (COCI) in the past two years, we retrieved the citations in the January 2021 Crossref dump to such invalid DOIs. We processed these citations by keeping track of their validity and the publishers responsible for uploading the related citation data in Crossref. Finally, we identified patterns of factual errors in the invalid DOIs and the regular expressions needed to catch and correct them. The outcomes of this research show that only a few publishers were responsible for and/or affected by the majority of invalid citations. We extended the taxonomy of DOI name errors proposed in past studies and defined more elaborated regular expressions that can clean a higher number of mistakes in invalid DOIs than prior approaches. The data gathered in our study can enable investigating possible reasons for DOI mistakes from a qualitative point of view, helping publishers identify the problems underlying their production of invalid citation data. Also, the DOI cleaning mechanism we present could be integrated into the existing process (e.g. in COCI) to add citations by automatically correcting a wrong DOI. This study was run strictly following Open Science principles, and, as such, our research outcomes are fully reproducible.

Aging yeast gain a competitive advantage on non-optimal carbon sources
Creators: name: Houseley, Jonathan

Year: 2017

description: Animals, plants and fungi undergo an aging process with remarkable physiological and molecular similarities, suggesting that aging has long been a fact of life for eukaryotes and one to which our unicellular ancestors were subject. Key biochemical pathways that impact longevity evolved prior to multicellularity, and the interactions between these pathways and the aging process therefore emerged in ancient single-celled eukaryotes. Nevertheless, we do not fully understand how aging impacts the fitness of unicellular organisms, and whether such cells gain a benefit from modulating rather than simply suppressing the aging process. We hypothesized that age-related loss of fitness in single-celled eukaryotes may be counterbalanced, partly or wholly, by a transition from a specialist to a generalist life-history strategy that enhances adaptability to other environments. We tested this hypothesis in budding yeast using competition assays and found that while young cells are more successful in glucose, highly aged cells outcompete young cells on other carbon sources such as galactose. This occurs because aged yeast divide faster than young cells in galactose, reversing the normal association between age and fitness. The impact of aging on single-celled organisms is therefore complex and may be regulated in ways that anticipate changing nutrient availability. We propose that pathways connecting nutrient availability with aging arose in unicellular eukaryotes to capitalize on age-linked diversity in growth strategy and that individual cells in higher eukaryotes may similarly diversify during aging to the detriment of the organism as a whole.

description: Meine Untersuchung „Austauschstudierende an den französischen Grandes Ecoles: Studieren zwischen Integration und Ausgrenzung?“ verfolgt das Ziel, die Bedeutung der Integration und der Ausgrenzung für die Austauschstudierenden, die einheimischen Studierenden, die Sprachdozent*innen, die Vereinsmitglieder aus unterschiedlichen studentischen Vereinen und die Berater*innen für Austauschstudierende von zwei exemplarischen Grandes Ecoles als Gast zu erfassen, zu untersuchen, welche Faktoren auf die Integration vs. Ausgrenzung der Austauschstudierenden einwirken, und in einem nächsten Schritt Schlussfolgerungen bezüglich der Integration vs. Ausgrenzung der Austauschstudierenden an Grandes Ecoles zu ziehen.
description: My study examined "Exchange students at the French Grandes Ecoles: studying between integration and exclusion?" The study aimed at understanding the meaning associated with integration and exclusion for the exchange students, the local students, the language teachers, the members of various student associations and the advisors to record exchange students from two exemplary Grandes Ecoles as guests. It also investigated which factors affected the integration versus exclusion of exchange students. Finally, conclusions regarding the integration versus exclusion of exchange students at Grandes Ecoles were drawn.

description: Integrity of layered structures, extensively used in modern industry, strongly depends on the quality of their interfaces; poor adhesion or delamination can lead to a failure of the structure. Can nonlinear waves help us to control the quality of layered structures? In this paper we numerically model the dynamics of a long longitudinal strain solitary wave in a split, symmetric layered bar. The recently developed analytical approach, based on matching two asymptotic multiple-scales expansions and the integrability theory of the KdV equation by the Inverse Scattering Transform, is used to develop an effective semi-analytical numerical approach for these types of problems. We also employ a direct finite-difference method and compare the numerical results with each other, and with the analytical predictions. The numerical modelling confirms that delamination causes fission of an incident solitary wave and, thus, can be used to detect the defect.

description: In a quantum network, distant observers sharing physical resources emitted by independent sources can establish strong correlations, which defy any classical explanation in terms of local variables. We discuss the characterization of nonlocal correlations in such a situation, when compared to those that can be generated in networks distributing independent local variables. We present an iterative procedure for constructing Bell inequalities tailored for networks: starting from a given network, and a corresponding Bell inequality, our technique provides new Bell inequalities for a more complex network, involving one additional source and one additional observer. The relevance of our method is illustrated on a variety of networks, for which we demonstrate significant quantum violations.

description: The role of p53 family member, p63 in oncogenesis is the subject of controversy. Limited research has been done on the clinical implications of p63 expression in diffuse large B-cell lymphoma (DLBCL). In this study, we assessed p63 expression in de novo DLBCL samples (n=795) by immunohistochemistry with a pan-p63-monoclonal antibody and correlated it with other clinicopathologic factors and clinical outcomes. p63 expression was observed in 42.5% of DLBCL, did not correlate with p53 levels, but correlated with p21, MDM2, p16INK4A, Ki-67, Bcl-6, IRF4/MUM-1 and CD30 expression, REL gains, and BCL6 translocation. p63 was an independent favorable prognostic factor in DLBCL, which was most significant in patients with International Prognostic Index (IPI) >2, and in activated-B-cell–like DLBCL patients with wide-type TP53. The prognostic impact in germinal-center-B-cell–like DLBCL was not apparent, which was likely due to the association of p63 expression with high-risk IPI, and potential presence of ∆Np63 isoform in TP63 rearranged patients (a mere speculation). Gene expression profiling suggested that p63 has both overlapping and distinct functions compared with p53, and that p63 and mutated p53 antagonize each other. In summary, p63 has p53-like and p53-independent functions and favorable prognostic impact, however this protective effect can be abolished by TP53 mutations.
Improving the accuracy of likelihood-based inference in meta-analysis and meta-regression

description: Random-effects models are frequently used to synthesise information from different studies in meta-analysis. While likelihood-based inference is attractive both in terms of limiting properties and of implementation, its application in random-effects meta-analysis may result in misleading conclusions, especially when the number of studies is small to moderate. The current paper shows how methodology that reduces the asymptotic bias of the maximum likelihood estimator of the variance component can also substantially improve inference about the mean effect size. The results are derived for the more general framework of random-effects meta-regression, which allows the mean effect size to vary with study-specific covariates.

description: Over a century of research into the origin of turbulence in wallbounded shear flows has resulted in a puzzling picture in which turbulence appears in a variety of different states competing with laminar background flow. At slightly higher speeds the situation changes distinctly and the entire flow is turbulent. Neither the origin of the different states encountered during transition, nor their front dynamics, let alone the transformation to full turbulence could be explained to date. Combining experiments, theory and computer simulations here we uncover the bifurcation scenario organising the route to fully turbulent pipe flow and explain the front dynamics of the different states encountered in the process. Key to resolving this problem is the interpretation of the flow as a bistable system with nonlinear propagation (advection) of turbulent fronts. These findings bridge the gap between our understanding of the onset of turbulence and fully turbulent flows.

description: An increase in students’ understanding of the nature of and interaction between knowledge formation across their curriculum subject enables them to be more confidence and independent learners with greater resilience to misinformation. This increase in academic self-concept and epistemic insight enables students to be rational and compassionate thinkers able to address complex social and technological issues concerning society today. In our 'Epistemic Insight Theory of Change' through Big Questions in the Classroom, we identify the value, processes and impact of engaging young people in interdisciplinary activities on their attainment.
