description: We consider 푛-channel signal detection system. Each 푖th channel could contain (or not contain) a signal. We suppose a signal is a function ƒ푖(t), t ∈ (0,1) observing in the white Gaussian noise of level ε > 0. Let 푘 be a number of channels which contain the signals. This number could be known or unknown. The functions ƒ푖 could be known or unknown as well. If shapes of functions ƒ푖 are unknown, then we consider nonparametric case. We suppose that functions ƒ푖 belongs to the Sobolev ball 횂σ where the smoothness parameter σ > 0 could be known or unknown as well. The cases, when 푘 or σ are unknown, lead to the "adaptive" problems. We are interested in the following problems: (1) How large the signals ƒ푖 should be in order to detect these signals with vanishing errors, as the number of channels 푛 tends to infinity? (2) What are the structures of test procedures which provide the detection of signals with the vanishing errors, if it is possible? We show that there are two main types of results in the problems which, roughly, correspond to the cases either 푘 is "large" (this means 푘 >> 푛½ in the problem) or 푘 is "small" (this means 푘 << 푛½).

description: Cet article se fonde sur un travail photographique mené au sein d’un couvent en Suisse romande qui a pour particularité d’avoir créé, dans ses murs, un établissement de soins pour religieuses et religieux âgés géré par des professionnels laïcs. Bien que bénéficiant d’une grande liberté quant à la prise de photos dans les différents espaces du couvent, j’ai plusieurs fois été confrontée à des réticences, voire des refus, qui n’étaient pas forcément le fait de la personne sur laquelle je pointais l’objectif, mais motivés par la situation photographiée. Ces réticences me transmettaient, verbalement, le message du « non-photographiable ». Analyser la frontière entre le photographiable et le non-photographiable (Bourdieu 1965a) permet de mettre au jour les normes et valeurs qui sont à l’œuvre au sein du couvent, non pas de façon homogène pour l’ensemble des acteurs, mais de façon différenciée selon les positions de ces acteurs (professionnels, résidents).
description: This article is based on photographic work conducted in a convent located in Western Switzerland. Its particularity stems from the fact that a nursing home for elderly nuns is managed by secular professionals in specific areas of the convent. Although I was free to take pictures in different spaces of the convent, on several occasions I met with reluctance, even refusals, which were not necessarily linked directly to the person on whom I was focussing but rather to the situation I was photographing. This reluctance was a verbal clue as what was "not to be photographed." Analyzing the border between what is photographable and what is not (Bourdieu 1965a) allows us to uncover the norms and values of the convent, which are not applicable to all actors homogenously but rather are experienced differently according to the position of different actors (both professionals and residents).

description: We introduce the notion of finite BRST-antiBRST transformations, both global and field-dependent, with a doublet $λ_{a}$, $a=1,2$, of anticommuting Grassmann parameters and find explicit Jacobians corresponding to these changes of variables in Yang-Mills theories. It turns out that the finite transformations are quadratic in their parameters. At the same time, exactly as in the case of finite field-dependent BRST transformations for the Yang-Mills vacuum functional, special field-dependent BRST-antiBRST transformations, with $s_{a}$-potential parameters $λ_{a}=s_{a}Λ$ induced by a finite even-valued functional $Λ$ and by the anticommuting generators $s_{a}$ of BRST-antiBRST transformations, amount to a precise change of the gauge-fixing functional. This proves the independence of the vacuum functional under such BRST-antiBRST transformations. We present the form of transformation parameters that generates a change of the gauge in the path integral and evaluate it explicitly for connecting two arbitrary $R_{ξ}$-like gauges. For arbitrary differentiable gauges, the finite field-dependent BRST-antiBRST transformations are used to generalize the Gribov horizon functional $h$, given in the Landau gauge, and being an additive extension of the Yang-Mills action by the Gribov horizon functional in the Gribov-Zwanziger model. This generalization is achieved in a manner consistent with the study of gauge independence. We also discuss an extension of finite BRST-antiBRST\ transformations to the case of general gauge theories and present an ansatz for such transformations.

description: Der vorliegende Aufsatz untersucht anhand von Mikrodaten aus der Beschäftigtenstatistik die Lohn- und Beschäftigungseffekte der Mindestlohnregelungen, die durch das Entsendegesetz für alle gewerblichen Arbeiter im deutschen Baugewerbe im Jahr 1997 in Kraft traten. Angewendet wird ein Differenz-von-Differenzen Ansatz. Wir entwickeln eine Methode, die trotz fehlender Information über geleistete Arbeitsstunden eine Identifikation des Effekts erlaubt. Im Unterschied zu anderen Untersuchungen wird die Größe von Treatment- und Kontrollgruppe nicht exogen vorgegeben, sondern nach dem Maximum-Likelihood-Kriterium bestimmt. Unsere Ergebnisse zeigen für das Bauhauptgewerbe sowohl in Ost- als auch in Westdeutschland positive Lohneffekte der Mindestlohnregelung. Bezüglich der Beschäftigungswirkung ergeben sich negative Effekte für Ostdeutschland, positive, statistisch allerdings nicht bzw. nur schwach signifikante Effekte für Westdeutschland.

description: A new class of metastable de Sitter vacua is presented and analyzed in N =1 supergravity and string theory with tunable (infinitesimally small) value of the cosmological constant. They are based on a gauged R-symmetry and the minimal spectrum contains a vector and a linear multiplet of the string dilaton or of a compactification modulus. In the minimum of the scalar potential supersymmetry is broken by an expectation value of both a D- and F-term.

description: Die Frage, wie kollektive Bildgedächtnisse entstehen, ist eng verknüpft mit der Frage nach dem ästhetischen und informativen Gehalt derjenigen Bilder, aus denen sich diese Bildgedächtnisse speisen. Häufig repräsentieren sie historisch einschneidende Ereignisse oder Momente: Dies gilt für die oben genannten Bilder ebenso wie für Robert Capas Aufnahmen vom D-Day in der Normandie, das Bild des sogenannten Tank Man in Peking 1989 oder Bilder vom Einschlag der Flugzeuge in das World Trade Center im September 2001. Andere ikonische Bilder zeigen historische Personen in einer Weise, die deren „Wesen“ besonders gut zum Ausdruck bringt (oder zu bringen scheint). Zu dieser Gruppe von Bildern zählen das millionenfach reproduzierte Porträt von Ernesto „Che“ Guevara, ein Schnappschuss von Albert Einstein mit herausgestreckter Zunge oder das Bild von Marilyn Monroe mit fliegendem Rock auf einem U-Bahnschacht. Alle diese Bilder haben ästhetische Qualitäten, die ihre massenhafte Reproduktion und die daraus resultierende Ikonisierung plausibel erscheinen lassen.

description: We introduce an invariant linked to some foundational questions in geometric measure theory and provide bounds on this invariant by decomposing an arbitrary cycle into uniformly rectifiable pieces. Our invariant measures the difficulty of cutting a nonorientable closed manifold or mod-2 cycle in $\mathbb{R}^n$ into orientable pieces, and we use it to answer some simple but long-open questions on filling volumes and mod-$ν$ currents.

description: We determine the asymptotic behavior of the maximum subgraph density of large random graphs with a prescribed degree sequence. The result applies in particular to the Erdős-Rényi model, where it settles a conjecture of Hajek [IEEE Trans. Inform. Theory 36 (1990) 1398-1414]. Our proof consists in extending the notion of balanced loads from finite graphs to their local weak limits, using unimodularity. This is a new illustration of the objective method described by Aldous and Steele [In Probability on Discrete Structures (2004) 1-72 Springer].

description: Interference in wireless networks degrades the signal quality at the terminals. However, it can potentially enhance the secrecy rate. This paper investigates the secrecy rate in a two-user interference network where one of the users, namely user 1, requires to establish a confidential connection. User 1 wants to prevent an unintended user of the network to decode its transmission. User 1 has to transmit such that its secrecy rate is maximized while the quality of service at the destination of the other user, user 2, is satisfied, and both user's power limits are taken into account. We consider two scenarios: 1) user 2 changes its power in favor of user 1, an altruistic scenario, 2) user 2 is selfish and only aims to maintain the minimum quality of service at its destination, an egoistic scenario. It is shown that there is a threshold for user 2's transmission power that only below or above which, depending on the channel qualities, user 1 can achieve a positive secrecy rate. Closed-form solutions are obtained in order to perform joint optimal power control. Further, a new metric called secrecy energy efficiency is introduced. We show that in general, the secrecy energy efficiency of user 1 in an interference channel scenario is higher than that of an interference-free channel.

description: We establish several finiteness properties of groups defined by algebraic difference equations. One of our main results is that a subgroup of the general linear group defined by possibly infinitely many algebraic difference equations in the matrix entries can indeed be defined by finitely many such equations. As an application, we show that the difference ideal of all difference algebraic relations among the solutions of a linear differential equation is finitely generated.

description: Dans un contexte d’EPS, nous avons comme objectif de trouver les moyens pédagogiques de motiver nos élèves, notamment dans les disciplines individuelles comme la gymnastique aux agrès. Pour ce faire, nous nous sommes intéressés à l’effet des feedbacks vidéo guidés aux anneaux balançants et au mini-trampoline. Nous avons appliqué le concept théorique de l’intérêt en situation (IS), selon le modèle de Chen et al. (2001). Trois classes (11VG filles ; 9VP garçons ; DEP mixte) d’un établissement lausannois ont vécu quatre leçons d’EPS dans des situations avec feedback vidéo guidé par l’enseignant ou par l’élève, dans les deux disciplines. A la fin de chaque leçon, un questionnaire de 19 items permettant de tester l’intérêt en situation et validé par Roure (2016), a été passé. Les résultats indiquent une différence significative dans les dimensions de l’intérêt en situation entre les deux conditions de feedback. Dans la condition de feedback par l’enseignant, les résultats indiquent que les dimensions du défi (DEF) et de la nouveauté (NVE) sont significativement plus élevées que dans le feedback par élève. A contrario, dans la condition de feedback par les élèves, la dimension du plaisir instantané (PI) est significativement plus élevée. Cependant, aucune différence concernant l’intérêt total (IT) n’a été observée entre les deux conditions, ni entre les deux genres (garçons et filles). L’absence de différence significative d’intérêt total entre les deux conditions s’explique par la nature des activités jugées comme peu attrayantes et comportant un niveau de défi trop peu adapté. En conclusion, les activités physiques individuelles comme celles pratiquées doivent être adaptées au niveau de chacun. L’outil numérique permet d’ajouter une méthode d’enseignement qui permettra, couplée à l’intervention d’un spécialiste en EPS, des situations d’apprentissages attrayantes et variées. Ceci afin que l’élève s’engage pleinement dans la tâche.

description: We consider lift-and-project methods for combinatorial optimization problems and focus mostly on those lift-and-project methods which generate polyhedral relaxations of the convex hull of integer solutions. We introduce many new variants of Sherali--Adams and Bienstock--Zuckerberg operators. These new operators fill the spectrum of polyhedral lift-and-project operators in a way which makes all of them more transparent, easier to relate to each other, and easier to analyze. We provide new techniques to analyze the worst-case performances as well as relative strengths of these operators in a unified way. In particular, using the new techniques and a result of Mathieu and Sinclair from 2009, we prove that the polyhedral Bienstock--Zuckerberg operator requires at least $\sqrt{2n}- \frac{3}{2}$ iterations to compute the matching polytope of the $(2n+1)$-clique. We further prove that the operator requires approximately $\frac{n}{2}$ iterations to reach the stable set polytope of the $n$-clique, if we start with the fractional stable set polytope. Lastly, we show that some of the worst-case instances for the positive semidefinite Lovász--Schrijver lift-and-project operator are also bad instances for the strongest variants of the Sherali--Adams operator with positive semidefinite strengthenings, and discuss some consequences for integrality gaps of convex relaxations.

description: Mechanisms selecting for the evolution of cooperative breeding are hotly debated. While kin selection theory has been the central paradigm to explain the seemingly altruistic behaviour of non-reproducing helpers, it is increasingly recognized that direct fitness benefits may be highly relevant. The group augmentation hypothesis proposes that alloparental care may evolve to enhance group size when larger groups yield increased survival and/or reproductive success. However, there is a lack of empirical tests. Here we use the cooperatively breeding cichlid fish Neolamprologus pulcher, in which group size predicts survival and group stability, to test this hypothesis experimentally by prompting two cooperative tasks: defence against an egg predator and digging out sand from the breeding shelter. We controlled for alternative mechanisms such as kin selection, load lightening and coercion. As predicted by the group augmentation hypothesis, helpers increased defence against an egg predator in small compared with large groups. This difference was only evident in large helpers owing to size-specific task specialization. Furthermore, helpers showed more digging effort in the breeding chamber compared with alternative personal shelters, indicating that digging is an altruistic service to the dominant breeders.

description: This work concerns the quantum Lorentzian and Euclidean black hole non-linear sigma models. For the Euclidean black hole sigma model an equilibrium density matrix is proposed, which reproduces the modular invariant partition function from the 2001 paper of Maldacena, Ooguri and Son. For the Lorentzian black hole sigma model, using its formulation as a gauged ${\rm SL}(2,\mathbb{R})$ WZW model, we describe the linear and Hermitian structure of its space of states and also propose an expression for the equilibrium density matrix. Our analysis is guided by the results of the study of a certain critical, integrable spin chain. In the scaling limit, the latter exhibits the key features of the Lorentzian black hole sigma model including the same global symmetries, the same algebra of extended conformal symmetry and a continuous spectrum of conformal dimensions.

description: In this study, the phenomenon of pornography is used as a lens through which I attempt to portray the entanglement of Artificial Intelligence (AI) and power. For this investigation, I consider two artifacts at the intersection of ML and pornography. The first one, content moderation, primarily focuses on removing undesired content, such as pornography, from social media platforms. Deepfakes, the second application, are manipulated videos in which arbitrary faces are inserted through the use of Deep Learning (DL) to create realistic footage. By examining the concrete effects of the ML systems of content moderation systems and pornographic deepfakes, I have found that they are involved in reinforcing heteronormativity, hegemonic conceptions of masculinity and femininity, and manifesting exploitative material conditions, which are components of what I have termed hegemonic sexuality. These effects are achieved through an operation of power that acts both productively and repressively and uses material and discursive mechanisms.
Mixed and non-competitive enzyme inhibition: underlying mechanisms and mechanistic irrelevance of the formal two-site model

description: The formal mechanism of linear mixed and non-competitive enzyme inhibition implies the binding of inhibitors to both the active site of the free enzyme in competition with the substrate, and to an allosteric site on the enzyme-substrate complex. However, it is evident from a review of the scientific literature that the two-site mechanism is frequently mistaken as the actual underlying mechanism of mixed inhibition. In this study, we conducted a comprehensive assessment of the mechanistic relevance of this type of inhibition using a statistical approach. By combining a statistical analysis of the inhibition cases documented in the BRENDA database with a theoretical investigation of inhibition models, we conclude that mixed inhibitors exclusively bind to the active site of enzymes. Hence ruling out any implication of allosteric sites and depriving the two-site model of any mechanistic relevance.

description: Significant academic achievement disparities between urban and rural areas in China highlight a pressing concern. Our study aims to illuminate the intricate interplay among educational investments, gender, and Hukou status, which is defined here as rural or urban residential status. By leveraging two-way ANOVA and ordinal logistic regression model, we strive to decipher the complexities within these associations. Our findings reveal an intriguing pattern: female students, particularly urban ones, achieve higher class ranks. The relationship between Hukou and academic standing is less straightforward, suggesting the role of other factors such as parental education and household equity. While our study primarily identifies patterns and associations, the insights gained contribute valuable understanding to the field of educational equity. These findings could potentially guide policy dialogue, with the ultimate objective of fostering a more balanced educational landscape in China.

description: This work presents a modified Kedem-Katchalsky equations for osmosis through nano-pore. osmotic reflection coefficient of a solute was found to be chiefly affected by the entrance of the pore while filtration reflection coefficient can be affected by both the entrance and the internal structure of the pore. Using an analytical method, we get the quantitative relationship between osmotic reflection coefficient and the molecule size. The model is verified by comparing the theoretical results with the reported experimental data of aquaporin osmosis. Our work is expected to pave the way for a better understanding of osmosis in bio-system and to give us new ideas in designing new membranes with better performance.

description: Mechanisms selecting for the evolution of cooperative breeding are hotly debated. While kin selection theory has been the central paradigm to explain the seemingly altruistic behaviour of non-reproducing helpers, it is increasingly recognized that direct fitness benefits may be highly relevant. The group augmentation hypothesis proposes that alloparental care may evolve to enhance group size when larger groups yield increased survival and/or reproductive success. However, there is a lack of empirical tests. Here we use the cooperatively breeding cichlid fish Neolamprologus pulcher, in which group size predicts survival and group stability, to test this hypothesis experimentally by prompting two cooperative tasks: defence against an egg predator and digging out sand from the breeding shelter. We controlled for alternative mechanisms such as kin selection, load lightening and coercion. As predicted by the group augmentation hypothesis, helpers increased defence against an egg predator in small compared to large groups. This difference was only evident in large helpers due to size-specific task specialization. Furthermore, helpers showed more digging effort in the breeding chamber compared to alternative personal shelters, indicating that digging was an altruistic service to the dominant breeders.

description: Iterative methods for fitting a Gaussian Random Field (GRF) model via maximum likelihood (ML) estimation requires solving a nonconvex optimization problem. The problem is aggravated for anisotropic GRFs where the number of covariance function parameters increases with the dimension. Even evaluation of the likelihood function requires $O(n^3)$ floating point operations, where $n$ denotes the number of data locations. In this paper, we propose a new two-stage procedure to estimate the parameters of second-order stationary GRFs. First, a convex likelihood problem regularized with a weighted $\ell_1$-norm, utilizing the available distance information between observation locations, is solved to fit a sparse precision (inverse covariance) matrix to the observed data. Second, the parameters of the covariance function are estimated by solving a least squares problem. Theoretical error bounds for the solutions of stage I and II problems are provided, and their tightness are investigated.

description: We introduce the notions of pointwise almost h-slant submanifolds and pointwise almost h-semi-slant submanifolds as a generalization of slant submanifolds, pointwise slant submanifolds, semi-slant submanifolds, and pointwise semi-slant submanifolds. We have characterizations and investigate the integrability of distributions, the conditions for such distributions to be totally geodesic foliations, the mean curvature vector fields on totally umbilic submanifolds, the properties of h-slant functions and h-semi-slant functions, the properties of non-trivial warped product proper pointwise h-semi-slant submanifolds. We also obtain topological properties on proper pointwise almost h-slant submanifolds and give an inequality for the squared norm of the second fundamental form in terms of the warping function and h-semi-slant functions for a warped product submanifold in a hyperkähler manifold. Finally, we give some examples of such submanifolds.

description: We make many new observations on primitive roots modulo primes. For an odd prime $p$ and an integer $c$, we establish a theorem concerning $\sum_g(\frac{g+c}p)$, where $g$ runs over all the primitive roots modulo $p$ among $1,\ldots,p-1$, and $(\frac{\cdot}p)$ denotes the Legendre symbol. On the basis of our numerical computations, we formulate 35 conjectures involving primitive roots modulo primes. For example, we conjecture that for any prime $p$ there is a primitive root $g3$ there is a prime $q3$ there exists a Fibonacci number $F_k3$.

description: As oxygen negatively affects most production processes in the metalworking industry, a truly oxygen-free production environment appears attractive in terms of the resulting material and component properties. This overview summarizes research conducted within the Collaborative Research Centre (CRC) 1368. The objectives of this CRC are twofold. First, a fundamental understanding of the mechanisms that govern the interaction between a metal surface and the environment is established. Second, it is researched how this understanding can be exploited to improve current production processes and even develop completely new ones. Herein, data obtained within the first funding period, which already demonstrate that significant effects can be realized in processes such as thermal spraying, cold rolling, compound casting, laser brazing, milling or hot stamping to name just a few examples, are presented. In addition, key aspects such as initial deoxidation of the workpieces, their transport under conditions that prevent reoxidation, and the tools needed to establish and control an oxygen-free process environment are given, and the ramifications with respect to actual applications are discussed.
The US Term Structure and Central Bank Policy

description: The expectations hypothesis of the term structure (EHT) implies cointegration between interest rates of different maturities and predicts certain values for adjustment speed. We estimate reduced-form vector error correction models of the US term structure. These are derived from a structural model combining the EHT, autocorrelated risk premia, interest rate smoothing and monetary policy feedback, which is able to capture a wide range of empirical outcomes. We explicitly test the necessary preconditions for the validity of the theoretical model. Premia persistence rises with longer-rate maturity, while the influence of the according spreads in the central bank reaction function diminishes.

Supplemental Material from Beyond facial width-to-height ratios: bizygomatic width is highly sexually dimorphic when adjusting for allometry

description: A large and ever-growing literature implicates male facial width-to-height ratio (bizygomatic width divided by facial height) as a secondary sexual trait linked to numerous physical and psychological perceptions. However, this research is based entirely on the premise that bizygomatic width is sexually dimorphic, which recent research has called into question. Unfortunately, statisticians for the last 125 years have noted that morphological ratio measurements may engender spurious correlations and biased effect-size estimates. In the current study, we find that bizygomatic width is highly sexually dimorphic (equivalent d = 1.39), even after adjusting for 92 allometric measurements, including multiple facial height and other craniofacial measurements (equivalent d = 1.07) in a sample of 6068 men and women. By contrast, facial width-to-height ratio (fWHR) measurements demonstrated a statistical pattern consistent with the age-old argument that morphological ratio measurements may engender spurious correlations and biased effect-size estimates. Thus, when avoiding facial ratio measurements and adjusting for allometry in craniofacial measures, we found strong support for a key premise in the human evolutionary and behavioural sciences that bizygomatic width exhibits male-biased sexual dimorphism.
