Evasão da Resposta Imune
Vírus da hepatite C

description: Introdução: O vírus da hepatite C (HCV) é a causa dos principais casos de cronificação das hepatites virais. Esse vírus infecta as células do fígado e produz algumas proteínas, das quais se destaca a NS3/4A que tem a capacidade de clivar a via de sinalização celular para infecção viral. Nesse estudo, foi abordado como o HCV consegue escapar da imunidade inata. Materiais e Métodos: Para elaboração do estudo foi realizado revisão de literatura consultando a Literatura Internacional em Ciências da Saúde (PubMed/MEDLINE) utilizando os termos “Imunidade Inata”, “Evasão da Resposta Imune” e “Vírus da hepatite C”. Foram incluídos artigos de 2012 a 2022 que tiveram relação na íntegra com o tema pesquisado. Resultados de Discussão:  Na imunidade inata, há três principais tipos de receptores capazes de identificar padrões moleculares associados ao patógeno (PAMPs), tais como TLR, RLR e NLR. Eles são importantes, pois fazem o reconhecimento do material genético viral, assim iniciando uma cadeia de sinalização que culmina na liberação do interferon do tipo I (IFN). Contudo, o HCV consegue inibir essa sinalização através de sua proteína não estrutural chamada NS3/4A. Essa, cliva uma proteína adaptadora, assim, impedindo a produção do IFN. Dessa forma o vírus consegue escapar do sistema imune e permanecer por mais tempo no hospedeiro. Conclusões: Uma compreensão dos mecanismos pelos quais o HCV utiliza para escapar no sistema imune, é crucial para o desenvolvimento de estratégias mais eficazes no combate à hepatite C.

description: We discuss two generalizations of Lie groupoids. One consists of Lie $n$-groupoids defined as simplicial manifolds with trivial $π_{k\geq n+1}$. The other consists of stacky Lie groupoids $\cG\rra M$ with $\cG$ a differentiable stack. We build a 1-1 correspondence between Lie 2-groupoids and stacky Lie groupoids up to a certain Morita equivalence. We prove this in a general set-up so that the statement is valid in both differential and topological categories. \Equivalences of higher groupoids in various categories are also described.

description: In diesem Beitrag untersuchen wir pädagogische Interaktionen in Schule und Kindertagesstätte, die sich empirisch als nicht selbstläufige Interaktionen zeigen. Wir weisen vor dem Hintergrund konversationsanalytischer Studien zur Lehrer*innen-Schüler*innen-Interaktion auf die Bedeutung sozialer Identitäten für die Organisation der Interaktion in institutionellen, asymmetrischen Settings hin und grenzen diese von symmetrisch organisierten Interaktionen ab. An zwei empirischen Beispielen thematisieren wir die methodischen Folgen der institutionellen Rahmung von pädagogischen Interaktionen für die formale Analyse der Interaktionsorganisation und schlagen eine Erweiterung der Kategorien zu deren Bestimmung vor.

description: There have been suggestions that heat caused by cerebral metabolic activity may constrain mammalian brain evolution, architecture, and function. This article investigates physical limits on brain wiring and corresponding changes in brain temperature that are imposed by thermodynamics of heat balance determined mainly by Na$^{+}$/K$^{+}$-ATPase, cerebral blood flow, and heat conduction. It is found that even moderate firing rates cause significant intracellular Na$^{+}$ build-up, and the ATP consumption rate associated with pumping out these ions grows nonlinearly with frequency. Surprisingly, the power dissipated by the Na$^{+}$/K$^{+}$ pump depends biphasically on frequency, which can lead to the biphasic dependence of brain temperature on frequency as well. Both the total power of sodium pumps and brain temperature diverge for very small fiber diameters, indicating that too thin fibers are not beneficial for thermal balance. For very small brains blood flow is not a sufficient cooling mechanism deep in the brain. The theoretical lower bound on fiber diameter above which brain temperature is in the operational regime is strongly frequency dependent but finite due to synaptic depression. For normal neurophysiological conditions this bound is at least an order of magnitude smaller than average values of empirical fiber diameters, suggesting that neuroanatomy of the mammalian brains operates in the thermodynamically safe regime. Analytical formulas presented can be used to estimate average firing rates in mammals, and relate their changes to changes in brain temperature, which can have important practical applications. In general, activity in larger brains is found to be slower than in smaller brains.

A gap analysis of prematurity education during the prenatal period
Creators: name: Hiserodt, Sydney
Publisher: name: No Publisher Supplied
Year: 2024

description: Purpose of the Project: Preterm birth preparedness education has been noted to be a missing piece of prenatal care. While in times of urgency it is provided, it is not regularly integrated into prenatal visits. This manuscript describes the implementation of a quality improvement (QI) project surrounding preterm birth education in the prenatal period. Methods: This was a secondary-analysis performed via retrospective chart review to determine the gaps in preterm birth education during the prenatal period at an urban center clinic, with a population at high-risk for the named phenomenon. Descriptive statistics and chi-square tests of association were used to analyze the data, and a clinical guide was created and proposed to staff to aide in improving this aspect of education at the project site. Results: Results indicated that most patients received preterm birth education. It was unanticipated that the majority of preterm birth education was provided by the clinic’s advanced-practice nurses. However, this education was noted to be frequent and non-specific. This element was noted in the majority of documentation, aside from nine patient charts that contained documentation of education aligning with the literature. Implications: It was concluded that preterm birth education at this site, while present, requires customization and detail for improved quality.

description: Using numerical simulations of a model disk system, we demonstrate that a machine learning generated order parameter can detect depinning transitions and different dynamic flow phases in systems driven far from equilibrium. We specifically consider monodisperse passive disks with short range interactions undergoing a depinning phase transition when driven over quenched disorder. The machine learning derived order parameter identifies the depinning transition as well as different dynamical regimes, such as the transition from a flowing liquid to a phase separated liquid-solid state that is not readily distinguished with traditional measures such as velocity-force curves or Voronoi tessellation. The order parameter also shows markedly distinct behavior in the limit of high density where jamming effects occur. Our results should be general to the broad class of particle-based systems that exhibit depinning transitions and nonequilibrium phase transitions.

Chiral Edge Currents for ac Driven Skyrmions in Confined Pinning Geometries

description: We show that ac driven skyrmion lattices in a weak pinning channel confined by regions of strong pinning exhibit edge transport carried by skipping orbits while skyrmions in the bulk of the channel undergo localized orbits with no net transport. The magnitude of the edge currents can be controlled by varying the amplitude and frequency of the ac drive or by changing the ratio of the Magnus force to the damping term. We identify a localized phase in which the orbits are small and edge transport is absent, an edge transport regime, and a fluctuating regime that appears when the ac drive is strong enough to dynamically disorder the skyrmion lattice. We also find that in some cases, multiple rows of skyrmions participate in the transport due to a drag effect from the skyrmion-skyrmion interactions. The edge currents are robust for finite disorder and should be a general feature of skyrmions interacting with confined geometries or inhomogeneous disorder under an ac drive. We show that similar effects can occur for skyrmion lattices at interfaces or along domain boundaries for multiple coexisting skyrmion species. The edge current effect provides a new method to control skyrmion motion, and we discuss the connection of these results with recent studies on the emergence of edge currents in chiral active matter systems and gyroscopic metamaterials.

description: Frauen waren und sind in Führungspositionen deutscher Wirtschaftsunternehmen unterrepräsentiert. Trotz politischer und betrieblicher Gleichstellungsmaßnahmen liegt der Anteil weiblicher* Führungskräfte in nahezu allen wirtschaftlichen Sektoren deutlich unter dem Anteil weiblicher* Beschäftigter insgesamt. Unabhängig davon, ob Organisationen als strukturell vergeschlechtlicht (Acker 1991, 2006) betrachtet werden oder die Aktualisierung von Geschlecht als kontextabhängig (z. B. Heintz/Nadai 1998) und kontingent analysiert wird, problematisiert die Geschlechterforschung, dass politische Gesetze und/oder einzelne Selbstverpflichtungen von Unternehmen jene mehr oder weniger subtilen Prozesse der Geschlechterdifferenzierung in Organisationen über die Ungleichheit hergestellt werden, kaum berühren. Anhand einer qualitativen Untersuchung in der Verwaltung eines großen Einzelhandelsunternehmens in Deutschland wird gezeigt, wie informelle Prozesse einer Geschlechtergleichstellung entgegenstehen - selbst wenn die Organisation eine Erhöhung des Frauenanteils in Führungspositionen wünscht und in den untersten Führungsebenen der Frauenanteil bereits vergleichsweise hoch ist.
description: Women remain underrepresented in management positions in Germany. Despite political, legal and company-level equal opportunities measures, the proportion of female* managers in almost all economic sectors is significantly lower than the overall proportion of female* employees. Irrespective of whether organizations are regarded as structurally gendered (Acker 1991, 2006) or gender is analyzed as a contextual and contingent category (i. e. Heintz/Nadai 1998), the main challenge is that political laws and/or individual voluntary commitments by companies hardly touch subtle processes of gender differentiation and inequality at organizational level. Using findings from a qualitative study in the administrative department of a large retail company in Germany, the article shows how informal processes oppose cultural change towards gender equality even though the organization aims at bringing more women into management position. And it shows that a larger percentage of women in lower management positions does not automatically improve their career opportunities.

description: We introduce a new model for a pairwise repulsive interaction potential of vortices in a type-II superconductor, consisting of superimposed six- and 12-fold anisotropies. Using numerical simulations we study how the vortex lattice configuration varies as the magnitudes of the two anisotropic interaction terms change. A triangular lattice appears for all values, and rotates through 30 degrees as the ratio of the six- and 12-fold anisotropy amplitudes is varied. The transition causes the VL to split into domains that have rotated clockwise or counter-clockwise, with domain boundaries that are "decorated" by dislocations consisting of five- and seven-fold coordinated vortices. We also find intra-domain dislocations and defects, and characterize them in terms of their energy cost. We discuss how this model could be generalized to other particle-based systems with anisotropic interactions, such as colloids, and consider the limit of very large anisotropy where it is possible to create cluster crystal states.

description: Der Beitrag untersucht den Wandel von In- und Exklusionsmechanismen von Frauen aus der Chemieindustrie von 1900 bis 1990 in einem interdisziplinären unternehmens- und epochenübergreifenden Vergleich anhand des Konzepts der sozialen Schließung nach Max Weber. Um die soziologische Theorie der sozialen Schließung von Berufsfeldern jedoch für die Sozialgeschichte nutzbar zu machen, bedarf es einer Operationalisierung dieses Konzepts. Mithilfe der Dimensionen der sozialen Ungleichheit zwischen den Geschlechtern nach Nancy Fraser können Schließungs- und Wandlungsprozesse über einen langen Zeitraum miteinander in Bezug gesetzt und nachvollzogen werden. Anhand einer Fallstudie zu Chemikerinnen und Laborantinnen in der deutschen Chemieindustrie zwischen 1900 und 1990 wird exemplarisch skizziert, wie sich Webers Theorie für eine interdisziplinär angelegte Sozialgeschichte praktisch umsetzen lässt.
description: This article examines the change in the mechanisms of inclusion and exclusion of women from the chemical industry from 1900-1990 in an interdisciplinary cross-company and cross-epoch comparison based on the concept of social closure according to Max Weber. In order to make the sociological theory of the social closure of occupational fields usable for social history, this concept needs to be operationalized. Based on Nancy Fraser’s dimensions of social injustice between the sexes, processes of closure and change can be related to each other and traced over a long period of time. Using a case study of female chemists and laboratory assistants in the German chemical industry between 1900 and 1990, it is shown how Weber's theory can be put into practice for an interdisciplinary social history.

title: Mechanistic Insight into CO₂​​​​​​​ Activation Using New Operando and Transient Spectroscopic Approaches​​​​​​​
Creators: name: Hess, Christian
Publisher: name: Dt. Bunsen-Ges. für Physikalische Chemie

description: The use of atmospheric or locally emitted carbon dioxide (CO₂)
as raw material for the production of chemicals and fuels
represents an important strategy for reducing the CO₂ concentration
in the atmosphere and the dependence on fossil fuels.
Heterogeneously catalyzed processes enable the activation
and transformation of CO₂, for example, via CO₂ hydrogenation,
via reforming of CO₂ or by using CO₂ as an oxidizing agent in
selective oxidation reactions. The rational design of better catalysts
requires a fundamental understanding of the underlying
reaction mechanism and the catalyst’s mode of operation. To
this end, the development and application of new experimental
approaches is urgently needed, providing a detailed analysis of
the respective catalyst and its structural dynamics, ultimately
enabling the identification of reaction intermediates and active
sites. To be of relevance, catalysts need to be monitored in
situ under real working conditions, preferably combined with a
simultaneous detection of activity, which is known as operando
analysis (see Fig. 1).

description: We show how vortices that support Majorana fermions when placed on a periodic pinning array can be used for vortex exchange and independent braiding by performing a series of specific moves with a probe tip. Using these braiding operations, we demonstrate realizations of a Hadamard and a CNOT gate. We specifically consider the first matching field at which there is one vortex per pinning site, and we show that there are two basic dynamic operations, move and exchange, from which basic braiding operations can be constructed in order to create specific logic gates. The periodic pinning array permits both control of the world lines of the vortices and freedom for vortex manipulation using a set of specific moves of the probe during which the probe tip strength and height remain unchanged. We measure the robustness of the different moves against thermal effects and show that the three different operations produce distinct force signatures on the moving tip.

description: In graph neural networks (GNNs), pooling operators compute local summaries of input graphs to capture their global properties, and they are fundamental for building deep GNNs that learn hierarchical representations. In this work, we propose the Node Decimation Pooling (NDP), a pooling operator for GNNs that generates coarser graphs while preserving the overall graph topology. During training, the GNN learns new node representations and fits them to a pyramid of coarsened graphs, which is computed offline in a pre-processing stage. NDP consists of three steps. First, a node decimation procedure selects the nodes belonging to one side of the partition identified by a spectral algorithm that approximates the \maxcut{} solution. Afterwards, the selected nodes are connected with Kron reduction to form the coarsened graph. Finally, since the resulting graph is very dense, we apply a sparsification procedure that prunes the adjacency matrix of the coarsened graph to reduce the computational cost in the GNN. Notably, we show that it is possible to remove many edges without significantly altering the graph structure. Experimental results show that NDP is more efficient compared to state-of-the-art graph pooling operators while reaching, at the same time, competitive performance on a significant variety of graph classification tasks.
Shear Banding, Intermittency, Jamming and Dynamic Phases for Skyrmions in Inhomogeneous Pinning Arrays

description: We examine driven skyrmion dynamics in systems with inhomogeneous pinning where a strip of strong pinning coexists with a region containing no pinning. For driving parallel to the strip, we find that the initial skyrmion motion is confined to the unpinned region and the skyrmion Hall angle is zero. At larger drives, a transition occurs to a phase in which motion also appears within the pinned region, creating a shear band in the skyrmion velocity, while the skyrmion Hall angle is still zero. As the drive increases further, the flow becomes disordered and the skyrmion Hall angle increases with drive until saturating at the highest drives when the system transitions into a moving crystal phase. The different dynamic phases are associated with velocity and density gradients across the pinning boundaries. We map out the dynamic phases as a function of pinning strength, skyrmion density, and Magnus force strength, and correlate the phase boundaries with features in the velocity-force curves and changes in the local and global ordering of the skyrmion structure. For large Magnus forces, the shear banding instability is replaced by large scale intermittent flow in the pinned region accompanied by simultaneous motion perpendicular to the direction of the drive, which appears as oscillations in the transport curves. We also examine the case of a drive applied perpendicular to the strip, where we find a jamming effect in which the skyrmion flow is blocked by skyrmion-skyrmion interactions until the drive is large enough to induce plastic flow.

description: A choreographic time crystal is a dynamic lattice structure in which the points comprising the lattice move in a coordinated fashion. These structures were initially proposed for understanding the motion of synchronized satellite swarms. Using simulations we examine colloids interacting with a choreographic crystal consisting of traps that could be created optically. As a function of the trap strength, speed, and colloidal filling fraction, we identify a series of phases including states where the colloids organize into a dynamic chiral loop lattice as well as a frustrated induced liquid state and a choreographic lattice state. We show that transitions between these states can be understood in terms of vertex frustration effects that occur during a certain portion of the choreographic cycle. Our results can be generalized to a broader class of systems of particles coupled to choreographic structures, such as vortices, ions, cold atoms, and soft matter systems.

description: Data from the first two orbits of the Sun by Parker Solar Probe reveal that the solar wind sunward of 50 solar radii is replete with plasma waves and instabilities. One of the most prominent plasma wave power enhancements in this region appears near the electron cyclotron frequency (f_ce). Most of this wave power is concentrated in electric field fluctuations near 0.7 f_ce and f_ce, with strong harmonics of both frequencies extending above f_ce. At least two distinct, often concurrent, wave modes are observed, preliminarily identified as electrostatic whistler-mode waves and electron Bernstein waves. Wave intervals range in duration from a few seconds to hours. Both the amplitudes and number of detections of these near-f_ce waves increase significantly with decreasing distance to the Sun, suggesting that they play an important role in the evolution of electron populations in the near-Sun solar wind. Correlations are found between the detection of these waves and properties of solar wind electron populations, including electron core drift, implying that these waves play a role in regulating the heat flux carried by solar wind electrons. Observation of these near-f_ce waves is found to be strongly correlated with near-radial solar wind magnetic field configurations with low levels of magnetic turbulence. A scenario for the growth of these waves is presented which implies that regions of low-turbulence near-radial magnetic field are a prominent feature of solar wind structure near the Sun.

description: Die deutsche Bundeswehr ist als militärische Organisation trotz ihrer umfassenden formalen Öffnung für Frauen und veränderter Aufgabenbereiche noch immer männlich konnotiert. Weibliche militärische Führungskräfte stellen in doppelter Hinsicht, als Frau und als Führungskraft, eine Abweichung und Verletzung bestehender stereotyper Zuschreibungen und Geschlechterdifferenzen dar. Der vorliegende Beitrag betrachtet die Bezugnahme auf die Kategorie Geschlecht durch weibliche Offiziere in diesem doppelt männlich konnotierten Kontext sowie deren Anwendung von Geschlechterdifferenzierungen. Es wird argumentiert, dass sie ein "strategisches Differenzmanagement" anwenden. Durch den Fokus auf die Auswirkungen der vertikalen Segregation im organisationalen Kontext auf das geschlechtliche Differenzmanagement ergänzt der Beitrag bisherige theoretische und empirische Ergebnisse bezüglich der Geschlechterkonstruktion und Geschlechterdifferenzierung in geschlechtsuntypischen Berufsbereichen.
description: The German armed forces as a military organization are still male connoted despite their broad formal inclusion of women and their changed tasks. Female military leaders can be seen in two respects, as women and as leaders, as a divergence and violation of existing stereotype attributions and gender differences. This paper examines the way how female military officers relate to the gender category and which gender differentiation they use in this twice male shaped context. It is argued that the female military officers use a "strategic difference management". The focus of this work lies on the effects of the vertical segregation on the gendered difference management in an organizational context. By that the work complements previous theoretical and empirical research regarding the construction of gender and gender differentiation in gender unusual occupational fields.
