The magnitude and direction of collider bias for binary variables

description: Suppose we are interested in the effect of variable $X$ on variable $Y$. If $X$ and $Y$ both influence, or are associated with variables that influence, a common outcome, called a collider, then conditioning on the collider (or on a variable influenced by the collider -- its "child") induces a spurious association between $X$ and $Y$, which is known as collider bias. Characterizing the magnitude and direction of collider bias is crucial for understanding the implications of selection bias and for adjudicating decisions about whether to control for variables that are known to be associated with both exposure and outcome but could be either confounders or colliders. Considering a class of situations where all variables are binary, and where $X$ and $Y$ either are, or are respectively influenced by, two marginally independent causes of a collider, we derive collider bias that results from (i) conditioning on specific levels of, or (ii) linear regression adjustment for, the collider (or its child). We also derive simple conditions that determine the sign of such bias.
Restricted developments in partizan misere game theory

description: Much progress has been made in misere game theory using the technique of restricted misere play, where games can be considered equivalent inside a restricted set of games without being equal in general. This paper provides a survey of recent results in this area, including two particularly interesting properties of restricted misere games: (1) a game can have an additive inverse that is not its negative, and (2) a position can be reversible through an end (a game with Left but not Right options, or vice versa). These properties are not possible in normal play and general misere play, respectively. Related open problems are discussed.

description: In this work the potentials of two X-ray methods, X-ray reflectivity (XRR) and X-ray standing waves (XSW) at grazing incidence (including X-ray fluorescence), using synchrotron radiation are experimentally evaluated. First, the theory of X-ray scattering in general, X-ray reflectivity, X-ray fluorescence and X-ray standing waves is discussed. Then, a focus is set onto calculation of X-ray standing waves at grazing angle of incidence. The experimental procedures for the above mentioned methods are outlined, and a combination of XRR and XSW is presented. Further, a computer program developed in this work to calculate X-ray standing waves intensity fields and permit evaluation of XSW scans is introduced. Finally, a wide variety of different layered and layer-like samples is presented that were characterized by a combination of XSW and XRR. The samples ranged from semiconductor samples (germanium layers on silicon substrates and implantations of As, Co and Zn ions in Si wafers), to bio-organic samples (cytochrome and nitrobenzene films, phospholipid bilayers as a model for biological membranes, metal-organic layers such as gold or silver clusters on polymer films), a multilayer laser mirror and ion distributions in a buffer solution. It is shown that the combination of XRR and XSW is especially powerful in comparison to other methods for samples that show little optical contrast between the layers (e.g. biological material) or are otherwise difficult to characterize by established methods. Further, the developed computer program permits evaluation of complicated structures not accessible by standard software.

description: We investigate the classical communication over quantum channels when assisted by no-signaling (NS) and positive-partial-transpose-preserving (PPT) codes, for which both the optimal success probability of a given transmission rate and the one-shot $ε$-error capacity are formalized as semidefinite programs (SDPs). Based on this, we obtain improved SDP finite blocklength converse bounds of general quantum channels for entanglement-assisted codes and unassisted codes. Furthermore, we derive two SDP strong converse bounds for the classical capacity of general quantum channels: for any code with a rate exceeding either of the two bounds of the channel, the success probability vanishes exponentially fast as the number of channel uses increases. In particular, applying our efficiently computable bounds, we derive an improved upper bound on the classical capacity of the amplitude damping channel. We also establish the strong converse property for the classical and private capacities of a new class of quantum channels. We finally study the zero-error setting and provide efficiently computable upper bounds on the one-shot zero-error capacity of a general quantum channel.

description: Subsynchrone Resonanzen (SSR) sind komplexe, dynamische Vorgänge bei denen ein Energieaustausch zwischen elektrischem Übertragungssystem und Generatorsatz stattfindet, in deren Folge unzulässig hohen Torsionsschwingungen auf den Wellensträngen auftreten, die zu schweren Schäden führen. Charakteristisch für die SSR ist das Auftreten von elektromagnetischen Momenten im Luftspalt des Generators mit Frequenzen, die unterhalb der synchronen Frequenz liegen. Um das dynamische Verhalten bei den niederfrequenten Vorgängen simulieren zu können wird ein Verfahren mittels Finite-Differenzen entwickelt, das eine exakte Erfassung des Generatorverhaltens bei subsynchronen Resonanzen erlaubt. Mit dem Modell können transiente Berechnungen mit diskreten Zeitschritten durchgeführt werden. Außerdem bietet das Modell die Möglichkeit, den Wellenstrang als Mehr-Massen-Modell einzubinden und über ein externes Vorschaltnetzwerk eine beliebige Netzkonfiguration vorzugeben. Des Weiteren werden bestehende und in der Praxis standardmäßig eingesetzte Modelle der Synchronmaschinen dahingehend untersucht, ob diese für die Simulation der subsynchronen Resonanzen eingesetzt werden können. Es wird gezeigt, dass das Ersatzschaltbild nach Park auch bei der Berechnung von Resonanzerscheinungen mit kleinen Frequenzen in gekoppelten elektromechanischen Systemen zufriedenstellende Ergebnisse liefert. Eine weitere Verbesserung in der Berechnung wird durch die Anpassung der Ersatzschaltbildparameter erzielt. Die Anpassung erfolgt über ein Optimierungsverfahren auf Grundlage der evolutionären Strategien aus den aufgezeichneten niederfrequenten Stromverläufen bei einer SSR.

description: This article explores congruence in the wake of the crises. It analyses (1) shifts in parties’ positions on multiple issue dimensions and (2) examines congruence between citizens and parliament in times of crisis. The article refers to three issue dimensions: left-right, migration and European integration. First, I hypothesise that shifts in party positions are more pronounced on newly contested issue dimensions, such as migration or European integration, than on the left-right dimension. Second, I argue that systemic congruence will increase over the course of time. Third, I posit that systemic congruence will increase particularly on newly contested issue dimensions, like migration and European integration. The study brings together a set of Western European countries: France, Germany, Great Britain, Spain and Sweden. The analysis is based on CHES- and ESS-data (2006–2018/2019) and explores congruence as a many-to-many relationship. In large part, the results confirm the hypotheses. First, party positions changed, and shifted particularly on the issue dimensions of European integration and migration. Second, systemic congruence increased in several cases. Third, the most profound changes are to be found on the issue dimension of European integration.

description: The Open Researcher and Contributor ID ORCID strives to enable transparent and trustworthy connections between researchers, their contributions, and their affiliations by providing a unique, persistent identifier for individuals to use as they engage in research, scholarship, and innovation activities. ORCID is therefore an essential piece of the puzzle for increasing the discoverability of researchers by disambiguating them from all the other researchers with the same or even a similar name and definitively connecting them with their research contribution metadata (e.g. their scholarly record). Furthermore, ORCID specifically addresses each of the FAIR findability principle components. The international non-profit organization ORCID , on which the initiative is based, already connects over 14 million persons worldwide with their research outcomes. In order to promote the widespread implementation of ORCID at universities and non-university research institutions in Germany, the project 'ORCID DE' was launched and is funded by the German Research Foundation (DFG). With the development of claiming services for the national bibliography of the German National Library and the BASE (Bielefeld Academic Search Engine), one of the world's most voluminous search engines especially for academic web resources, ORCID DE provides central tools for shaping the distribution and quality of metadata of scholarly communication from Germany. Furthermore the project fosters the interconnection of ORCID with other persistent identification (PID) systems and therefore contributes to more discoverability, accessibility, and visibility of research outcomes. As coordinator of the project, the Helmholtz Open Science Office makes an important contribution to improving scientific information management in the context of Open Science Further project partners of ORCID DE are Deutsche Nationalbibliothek , Universitätsbibliothek Bielefeld , DataCite - International Data Citation Initiative e. V. and Technische Informationsbibliothek (TIB) Hannover .

description: Loop-closure detection on 3D data is a challenging task that has been commonly approached by adapting image-based solutions. Methods based on local features suffer from ambiguity and from robustness to environment changes while methods based on global features are viewpoint dependent. We propose SegMatch, a reliable loop-closure detection algorithm based on the matching of 3D segments. Segments provide a good compromise between local and global descriptions, incorporating their strengths while reducing their individual drawbacks. SegMatch does not rely on assumptions of "perfect segmentation", or on the existence of "objects" in the environment, which allows for reliable execution on large scale, unstructured environments. We quantitatively demonstrate that SegMatch can achieve accurate localization at a frequency of 1Hz on the largest sequence of the KITTI odometry dataset. We furthermore show how this algorithm can reliably detect and close loops in real-time, during online operation. In addition, the source code for the SegMatch algorithm will be made available after publication.

description: An ideal $I$ on a cardinal $κ$ is called \emph{rigid} if all automorphisms of $P(κ)/I$ are trivial. An ideal is called \emph{$μ$-minimal} if whenever $G\subseteq P(κ)/I$ is generic and $X\in P(μ)^{V[G]}\setminus V$, it follows that $V[X]=V[G]$. We prove that the existence of a rigid saturated $μ$-minimal ideal on $μ^+$, where $μ$ is a regular cardinal, is consistent relative to the existence of large cardinals. The existence of such an ideal implies that GCH fails. However, we show that the existence of a rigid saturated ideal on $μ^+$, where $μ$ is an \emph{uncountable} regular cardinal, is consistent with GCH relative to the existence of an almost-huge cardinal. Addressing the case $μ=ω$, we show that the existence of a rigid \emph{presaturated} ideal on $ω_1$ is consistent with CH relative to the existence of an almost-huge cardinal. The existence of a \emph{precipitous} rigid ideal on $μ^+$ where $μ$ is an uncountable regular cardinal is equiconsistent with the existence of a measurable cardinal.

description: In the automotive industry, a manufacturer must perform several hundreds of tests on prototypes of a vehicle before starting its mass production. These tests must be allocated to suitable prototypes and ordered to satisfy temporal constraints and various kinds of test dependencies. To reduce costs, the manufacturer is interested in using the minimum number of prototypes. We apply Constraint Programming (CP) and a hybrid approach to solve the scheduling problem. Our CP method can achieve good feasible solutions even for our largest instances within a reasonable time. In comparison with existing methods, we can improve the solutions for most of our instances and reduce the average number of required prototypes. The hybrid approach uses mixed integer linear programming (MILP) to solve the planning part and CP to find the complete schedule. Although the hybrid approach is not as robust as CP with respect to data characteristics and additional constraints, it can complement CP in finding a better lower bound.

Earlier discussions of band bending in a semiconductor contacting a metal and liquid electrolyte solutions containing redox couples with different electrochemical potentials should not overshadow the fact that under absorption of photons takes place in a solar cell, which can generate free charge for an electrical circuit. Here we propose new band bending of ZnO and Cu2O semiconductors induced by a liquid self-assembled microdrop of a physiological salt solution.

description: This deliverable presents a summary of the Socio-Emotional Testing Agents (SETAs) that were developed as part of WP4. It begins by explaining the modular architecture of the SETAs and then presents the several components that were developed during the iv4XR project. These components pertain both to the behaviour of the SETAs as well as the automatic measurement of different components of user experience. At the end of the deliverable, we provide example usages of the SETAs and of how the different components can be used by designers to create tailored made user experience testing agents for their applications.
Optimal Shrinkage Estimator for High-Dimensional Mean Vector

description: In this paper we derive the optimal linear shrinkage estimator for the high-dimensional mean vector using random matrix theory. The results are obtained under the assumption that both the dimension $p$ and the sample size $n$ tend to infinity in such a way that $p/n \to c\in(0,\infty)$. Under weak conditions imposed on the underlying data generating mechanism, we find the asymptotic equivalents to the optimal shrinkage intensities and estimate them consistently. The proposed nonparametric estimator for the high-dimensional mean vector has a simple structure and is proven to minimize asymptotically, with probability $1$, the quadratic loss when $c\in(0,1)$. When $c\in(1, \infty)$ we modify the estimator by using a feasible estimator for the precision covariance matrix. To this end, an exhaustive simulation study and an application to real data are provided where the proposed estimator is compared with known benchmarks from the literature. It turns out that the existing estimators of the mean vector, including the new proposal, converge to the sample mean vector when the true mean vector has an unbounded Euclidean norm.

description: Many-body interactions in monolayer transition-metal dichalcogenides are strongly affected by their unique band structure. We study these interactions by measuring the energy shift of neutral excitons (bound electron-hole pairs) in gated WSe$_2$ and MoSe$_2$. Surprisingly, while the blueshift of the neutral exciton, $X^0$, in electron-doped samples can be more than 10~meV, the blueshift in hole-doped samples is nearly absent. Taking into account dynamical screening and local-field effects, we present a transparent and analytical model that elucidates the crucial role played by intervalley plasmons in electron-doped conditions. The energy shift of $X^0$ as a function of charge density is computed showing agreement with experiment, where the renormalization of $X^0$ by intervalley plasmons yields a stronger blueshift in MoSe$_2$ than in WSe$_2$ due to differences in their band ordering.
description: Compared with the previous version, this is an entirely new paper except for the experiment part. It took us 2 more years to get the theory straight and we hope it is right this time

description: An array of interesting activities for bioactive 3-substituted thiopyridines have previously been reported. Herein, a series of α- and β-(1-adamantylthio) analogs of 3-picoline and phenylpyridines were prepared and investigated for antimicrobial (agar dilution method against 21 strains of microorganisms) and antimalarial (against P. falciparum) activities. It was found that β-thiopyridines, 5-(1-adamantylthio)-3-picoline (7) and 3-(1-adamantylthio)-4-phenylpyridine (8) are novel antimicrobials and antimalarials. Significantly, analogs 7 and 8 are very potent antimicrobials with MIC range of 2-32 µg/mL where 8 being the most potent. The β-sulfides 7 and 8 selectively inhibited the growth of tested gram-positive bacteria, but inactive against gram-negative bacilli including the members of Enterobacteriaceae. This study identified new antimicrobials that represent promising lead compounds suitable for fur-ther preclinical and clinical development.

description: El presente artículo tiene como objetivo analizar el comercio de marihuana en la Costa Caribe colombiana de 1975 hasta 1985. Este trabajo se divide en tres partes. En la primera analizo las características geográficas y económicas de la Guajira, entre ellas, su condición fronteriza con Venezuela. En la segunda, se va determinar algunos factores que han propiciado las prácticas ilegales en la Guajira. Por último, voy analizar el tráfico de marihuana en la Guajira; los clanes que se vieron involucrados en dicho fenómeno; los lugares distribución y de acopio de este estupefaciente; los sectores que beneficiaron; y también se va a abordar el conflicto de dos familias guajiras que se vieron implicadas en la bonanza marimbera

description: Recently (Phys. Rev. Lett. 114 (2015), 210402) the influence of the so called "Wigner translations" (more generally-Lorentz trans- formations) on circularly polarized Gaussian packets ( providing the solution to Maxwell equations in paraxial approximation) has been studied. It appears that, within this approximation, the Wigner trans- lations have an efect of shifting the wave packet trajectory parallel to itself by an amount proportional to the photon helicity. It has been suggested that this shift may result from specific properties of the algebra of Poincare generators for massless particles. In the present letter we describe the general relation between transformation proper- ties of electromagnetic field on quantum and classical levels. It allows for a straightforward derivation of the helicity-dependent transforma- tion rules. We present also an elementary derivation of the formula for sideways shift based on classical Maxwell theory. Some comments are made concerning the generalization to higher helicities and the relation to the coordinate operator defined long time ago by Pryce.

description: En este documento se presenta un sistema de información como propuesta para mejorar la toma de decisiones en las Iglesias Cristianas en la ciudad de Cartagena de Indias y tiene como sustento teórico la importancia del buen manejo de la información para cualquier organización. Muchas iglesias en la ciudad padecen de un exceso de información y un escaso conocimiento sobre el manejo de la misma ya que la formación realizada por sus pastores se centra en el ámbito espiritual y no fueron preparados para administrar la oficina de su iglesia. Para el desarrollo de este proyecto se realizó una investigación sobre los modelos administrativos eclesiásticos que siguen las iglesias de la ciudad, del cual se concluyó que los cuatro tipos de administración más populares son el modelo tradicional bautista, el modelo de los doce, el modelo celular y el modelo de Jesús. En esta investigación también se abarcaron temas relacionados con diferentes ámbitos de la iglesia como las academias, niños, servicios, evento, entre otros; el uso de herramientas de gestión de información de membresía utilizada por las diferentes iglesias y el interés de esta en adquirir un sistema de información para el manejo de su información. Al analizar la metodología estos modelos, se determinó que el Modelo de Jesús era el más completo y que a su vez de él se podían desprender los demás. Teniendo en cuenta lo anterior, se desarrolló un software implementando el modelo de Jesús, de tal forma que pudiera ser utilizado por las iglesias que siguen los otros modelos de administración eclesiástica. Para esto se empleó la metodología RUP (proceso unificado de desarrollo de software) el cual incluye modelo de negocios, requerimientos, análisis y diseño, implementación, prueba, instalación y documentación.

description: This work defines two classes of processes, that we term {\it tempered fractional multistable motion} and {\it tempered multifractional stable motion}. They are extensions of fractional multistable motion and multifractional stable motion, respectively, obtained by adding an exponential tempering to the integrands. We investigate certain basic features of these processes, including scaling property, tail probabilities, absolute moment, sample path properties, pointwise Hölder exponent, Hölder continuity of quasi norm, (strong) localisability and semi-long-range dependence structure. These processes may provide useful models for data that exhibit both dependence and varying local regularity/intensity of jumps.

description: Sexual and reproductive health and rights are a central pillar for informed and integral sexuality since it represents an aspect of human life.
 The prejudices surrounding sex education have compromised their advances in the Mexican population. In consequence, it has generated misinformation, an increase in the rate of Sexually Transmitted Diseases (65.42%), inadequate use of contraceptives (28%), and teenage pregnancies (17.04%).
 For this reason, it is a must that medical students be informed and up-to-date to educate, prevent, and detect these problems involving sexual and reproductive health and rights.
 We do an intervention between August-November of 2022 to teach medical students about health and reproductive education topics. We carried out a breastfeeding campaign; a workshop on contraceptive methods and placement of the internal and external condom; a monkeypox clinical case presentation; rapid tests for hepatitis C, HIV, and syphilis campaign; a gestational diabetes talk; and a how to identify sexual acts talk. All the activities were open to medical students of any semester of the medical career from 3 universities in Tampico, Tamaulipas, Mexico.
