description: According to Wick's theorem, the second order self-energy corrections of hadrons in the hot and dense nuclear matter are calculated. Furthermore, the Feynman rules are summarized, and an effective formulation on quantum hadrodynamics at finite temperatures and densities is evaluated. As the strong couplings between nucleons are considered, the self-consistency of this method is discussed in the framework of relativistic mean-field approximation. Debye screening masses of the scalar and vector mesons in the hot and dense nuclear matter are calculated with this method in the relativistic mean-field approximation. The results are different from those of thermofield dynamics and Brown-Rho conjecture. Moreover, the effective masses of the photon and the nucleon in the hot and dense nuclear matter are discussed.

description: We present a modular Python library for computing many-body hydrodynamic and phoretic interactions between spherical active particles in suspension, when these are given by solutions of the Stokes and Laplace equations. Underpinning the library is a grid-free methodology that combines dimensionality reduction, spectral expansion, and Ritz-Galerkin discretization, thereby reducing the computation to the solution of a linear system. The system can be solved analytically as a series expansion or numerically at a cost quadratic in the number of particles. Suspension-scale quantities like fluid flow, entropy production, and rheological response are obtained at a small additional cost. The library is agnostic to boundary conditions and includes, amongst others, confinement by plane walls or liquid-liquid interfaces. The use of the library is demonstrated with six fully coded examples simulating active phenomena of current experimental interest.

description: We present spectroscopic and photometric observations of the cataclysmic variable CW 1045+525. Both the optical spectrum and the photometric lightcurve show a strong contribution of a K5V - M0V secondary. We derive an orbital period P_orb = 0.271278(1) d by measuring the radial velocities of the absorption lines of the secondary. The period and spectral type of the secondary suggest a distance of 350 - 700 pc. There is evidence for additional sources of line- and continuum emission, but no direct evidence of an accretion disc. We discuss several scenarios for the nature of CW 1045+525 on the basis of our results, finding a dwarf nova classification the most probable, although not completely satisfying, explanation for the observed characteristics.

Multi-Domain Neural Machine Translation with Word-Level Adaptive Layer-wise Domain Mixing

description: Many multi-domain neural machine translation (NMT) models achieve knowledge transfer by enforcing one encoder to learn shared embedding across domains. However, this design lacks adaptation to individual domains. To overcome this limitation, we propose a novel multi-domain NMT model using individual modules for each domain, on which we apply word-level, adaptive and layer-wise domain mixing. We first observe that words in a sentence are often related to multiple domains. Hence, we assume each word has a domain proportion, which indicates its domain preference. Then word representations are obtained by mixing their embedding in individual domains based on their domain proportions. We show this can be achieved by carefully designing multi-head dot-product attention modules for different domains, and eventually taking weighted averages of their parameters by word-level layer-wise domain proportions. Through this, we can achieve effective domain knowledge sharing, and capture fine-grained domain-specific knowledge as well. Our experiments show that our proposed model outperforms existing ones in several NMT tasks.

description: Pelethiphis crinitus (Berlese)
 Iphis crinitus Berlese, 1882a: 343; 1886: 10; 1892d: 40.
 Copriphis (Pelethiphis) crinitus.— Berlese, 1911: 185; Castagnoli & Pegazzano, 1985: 97.
 Iphis elongatus Berlese, 1882a: 345; Berlese, 1892d: 40. Synonymy by Berlese (1892d).
 Remarks. The identity of this species cannot be established with any confidence. Berlese (1882a) described Iphis crinitus from the dung beetle Atheucus variolosus from Calabria, Italy, but there are no specimens in the Berlese Acaroteca with that label data. Berlese (1886) then redescribed and illustrated Iphis crinitus from Atheucus variolosus from Apulia, Italy. One of us (PM) has examined two of Berlese's slides numbered 123/ 46 and 123/48. These two slides contain 19 specimens (males, females and deutonymphs) collected on Scarabaeus semipunctatus at San Vincenzo, Pisa. These slides are referred to Copriphis (Pelethiphis) crinitus by Castagnoli & Pegazzano (1985), although they are both labelled Copriphis (Pelethiphis) elongatus, and are not labelled as types. They are in very poor condition for examination, but they are clearly not conspecific with those that were well illustrated by Berlese (1886). The Berlese (1886) specimens have extremely long marginal setae, much longer than those of the San Vicenzo specimens. The San Vicenzo specimens could however be conspecific with those on slide number 4/12, which is labelled Copriphis (Pelethiphis) crinitus var. curtipilus (= Alliphis siculus) and listed under the name Eviphis siculus by Castagnoli & Pegazzano (1985), and collected from the same dung beetle host (Scarabaeus semipunctatus). The Berlese Acaroteca also contains vial number 6/257, labelled Iphis crinitus, from Florence, but those specimens have not been examined in this study.
 Berlese (1882a) (p. 69) described two species, Iphis crinitus (p. 343) and Iphis elongatus (p. 345), but later (Berlese 1892d) synonymised these two species. There are no types for either of these species in the Berlese Acaroteca, so the validity of this synonymy is also questionable. Despite the fact that the voucher slides in Florence are labelled Copriphis (Pelethiphis) elongatus, Berlese (1911) described another Copriphis species under the name Copriphis elongatus from America. In addition, Shoemake (1970) synonymised I. crinitus with Iphis ciliatus C. L. Koch, 1839, but that synonymy is not considered to be valid here. Our concept of Pelethiphis crinitus is based on the illustrations of Berlese (1886).

description: Racial inequities in healthcare in the US and the UK are well documented, yet disparities stubbornly persist at disturbing levels in high-income countries such as these. While some healthcare institutions have been using anti-bias training to address the problem, it has had no impact on reducing inequities. While well-intentioned, it could be argued that mere training, without legally enforceable procedures to reduce racial bias, will maintain the status quo.

description: This paper examines a tax/subsidy on hunters based on game population. The tax/subsidy is the difference between actual and optimal population multiplied by an individual, variable tax rate. The tax rate is, among other things, based on the difference between the marginal value of the game population to the hunter and the regulator and differences in user costs of the population. The paper shows that the population tax/subsidy secures a first-best optimum.

description: Optomechanically induced transparency is an important quantum phenomenon in cavity optomechanics. Here, we study the properties of optomechanically induced transparency in the simplest optomechanical system (consisting of one cavity and one mechanical resonator) considering the effect of non-rotating wave approximation (NRWA) that was ignored in previous works. With the NRWA effect, we find the ideal optomechanically induced transparency dip can be easily achieved, and the width of optomechanically induced transparency dip can become very narrow especially in unresolved sideband regime. Finally, we study the properties of optomechanically induced gain, and give the analytic expression about the maximum value of gain.

description: Risk management strategies are of increasing importance in agriculture. An important question is what type of risk management strategies are required to reduce farmers’ income risks? Applying a variance decomposition approach using data from more than 3,000 Swiss farms over a five-year period, this paper quantifies the direct and indirect effects of yields, prices and costs on net revenue variability at the farm level. We find that costs play only a minor role in determining income variability, but price and yield risks are of outmost importance and very crop-specific. For instance, price risks dominate for conventional wheat and sugar beet producers; while corn and barley producers tend to suffer more from production risks. Group comparisons and logistic regressions results show that more intensively producing farms tend to suffer more from price risk, while yield risks are dominant for less intensive producers.

description: Gravitationally lensed quasars are useful for studying astrophysics and cosmology, and enlarging the sample size of lensed quasars is important for multiple studies. In this work, we develop a lens search algorithm for four-image (quad) lensed quasars based on their time variability. In the development of the lens search algorithm, we constructed a pipeline simulating multi-epoch images of lensed quasars in cadenced surveys, accounting for quasar variabilities, quasar hosts, lens galaxies, and the PSF variation. Applying the simulation pipeline to the Hyper Suprime-Cam (HSC) transient survey, we generated HSC-like difference images of the mock lensed quasars from Oguri & Marshall's lens catalog. We further developed a lens search algorithm that picks out variable objects as lensed quasar candidates based on their spatial extent in the difference images. We tested our lens search algorithm with the mock lensed quasars and variable objects from the HSC transient survey. Using difference images from multiple epochs, our lens search algorithm achieves a high true-positive rate (TPR) of 90.1% and a low false-positive rate (FPR) of 2.3% for the bright quads with wide separation. With a preselection of the number of blobs in the difference image, we obtain a TPR of 97.6% and a FPR of 2.6% for the bright quads with wide separation. Even when difference images are only available in one single epoch, our lens search algorithm can still detect the bright quads with wide separation at high TPR of 97.6% and low FPR of 2.4% in the optimal seeing scenario, and at TPR of $\sim94%$ and FPR of $\sim5%$ in typical scenarios. Therefore, our lens search algorithm is promising and is applicable to ongoing and upcoming cadenced surveys, particularly the HSC transient survey and the Rubin Observatory Legacy Survey of Space and Time, for finding new lensed quasar systems.

description: In this article, we explore the factors leading winegrowers to apply pesticide doses exceeding the official recommendations. Our approach is founded on an original methodology that determines practices of overdosing by matching four databases in 2006: the Farm Accountancy Data Network (FADN); the cropping practices survey (PK) in the winegrowing sector; the e-phy database operated by the French Ministry of Agriculture and Food, which identifies authorised doses per input; and climatic data measured by the Météo France meteorological office. Our sample, which contains 105 vineyards throughout France, reveals that 50% of these winegrowers never overdose, while 24% systematically apply excessive doses of pesticides. The latter group benefits from a comfortable financial situation, but suffers from an unfavourable climate.

description: A number of studies have reported that mast cells (MCs) play a critical role in host immune defence against bacterial infections. These studies have shown that mast cells have the ability to recognize and engulf bacteria. This project aimed to investigate the effect of MCs on selected microbial pathogens and the effect of these pathogen and their products on MCs and other cell types (RBL-2H3 and J774A.1 cell lines). The phagocytic activity of sheep BMMC was studied by using bioluminescent strains of B. bronchiseptica and E. coli, and degranulation was followed by estimating beta-hexosaminidase release. The bioluminescent method is based on the assumption that the level of light output from bacteria is directly proportional to the number of viable bacterial cells. Comparison between light output of bioluminescent E. coli and B. bronchiseptica (Lux 95) in a short-run experiment (< 20 h) suggested that the correlation between bioluminescence output and optical density of the bioluminescent E. coli was not as good as with B. bronchiseptica (Lux 95). The difference is probably due to the fact that E. coli is a much more rapidly growing organism than B. bronchiseptica and will therefore reach stationary phase in a much shorter time. A problem encountered in this study with B. bronchiseptica (Lux 95) was that it had been derived from a laboratory strain that may have partially lost its virulence attributes. Comparison of B. bronchiseptica (Lux 95) strain with B. bronchiseptica (Bvg+) and B. bronchiseptica (Bvg-) strains revealed that it had more properties in common with the Bvg- than the Bvg+ mode and may not, therefore, have been an ideal strain for this study. Construction of further bioluminescent derivatives of a wild-type (Byg+) and avirulent (Bvg-) strains should be considered for future work. The bioluminescent method however, was shown to offer an easy and simple method of measuring the viability of the bacteria in real-time. Based on in vitro invasion assays, the kinetics of interaction between sheep BMMC and B. bronchiseptica (Lux 95) was followed. The data indicated for the first time, the presence of viable bioluminescent B. bronchiseptica within sheep BMMC, and this observation was confirmed by both viable count and TEM. For the first time, viable intracellular B. bronchiseptica (Lux 95) were shown within sheep BMMC. These results establish baseline data for individual and age-related variation in sheep, BMMC phagocytic function, and form a basis for further evaluation of other functions such as chemotaxis, oxidative burst and clearance of bacterial infection by mast cells, either in sheep or other animal models.

description: This article aims to identify the influences of a variety of factors on the practice of agricultural direct-to-consumer sales activities. Using data from the 2007 Farm Structure Survey, representative of the all the farms in France, it shows that the propensity to sell directly to consumers is significantly influenced by several factors both internal to the agricultural sector (farms’ economic size and farm type, product quality, agrotourism and contract work activities, and the work team characteristics of family and hired labour, gender, educational level, farm-head age) and external to it (market characteristics, including local markets). It makes an original contribution to the literature on the subject, highlighting that beyond the traits they have in common, farms in direct-to-consumer sales present differentiated characteristics depending on the type of product they produce.

description: Despite all the other cells that have the potential to prevent cancer development and metastasis through tumour suppressor proteins, cancer cells can upregulate the ubiquitin–proteasome system (UPS) by which they can degrade tumour suppressor proteins and avoid apoptosis. This system plays an extensive role in cell regulation organized in two steps. Each step has an important role in controlling cancer. This demonstrates the importance of understanding UPS inhibitors and improving these inhibitors to foster a new hope in cancer therapy. UPS inhibitors, as less invasive chemotherapy drugs, are increasingly used to alleviate symptoms of various cancers in malignant states. Despite their success in reducing the development of cancer with the lowest side effects, thus far, an appropriate inhibitor that can effectively inactivate this system with the least drug resistance has not yet been fully investigated. A fundamental understanding of the system is necessary to fully elucidate its role in causing/controlling cancer. In this review, we first comprehensively investigate this system, and then each step containing ubiquitination and protein degradation as well as their inhibitors are discussed. Ultimately, its advantages and disadvantages and some perspectives for improving the efficiency of these inhibitors are discussed.

Explicitly, we demonstrate that a space $X$ has the FPP if and only if 2 is the minimal cardinality of open covers $\{U_i\}$ of $X$ such that each $U_i$ admits a continuous local section for $π_{2,1}^X$. This characterization connects a standard problem in fixed point theory to current research trends in topological robotics.

description: The holographic renormalization group (RG) is reviewed in a self-contained manner. The holographic RG is based on the idea that the radial coordinate of a space-time with asymptotically AdS geometry can be identified with the RG flow parameter of the boundary field theory. After briefly discussing basic aspects of the AdS/CFT correspondence, we explain how the notion of the holographic RG comes out in the AdS/CFT correspondence. We formulate the holographic RG based on the Hamilton-Jacobi equations for bulk systems of gravity and scalar fields, as was introduced by de Boer, Verlinde and Verlinde. We then show that the equations can be solved with a derivative expansion by carefully extracting local counterterms from the generating functional of the boundary field theory. The calculational methods to obtain the Weyl anomaly and scaling dimensions are presented and applied to the RG flow from the N=4 SYM to an N=1 superconformal fixed point discovered by Leigh and Strassler. We further discuss a relation between the holographic RG and the noncritical string theory, and show that the structure of the holographic RG should persist beyond the supergravity approximation as a consequence of the renormalizability of the nonlinear sigma model action of noncritical strings. As a check, we investigate the holographic RG structure of higher-derivative gravity systems, and show that such systems can also be analyzed based on the Hamilton-Jacobi equations, and that the behaviour of bulk fields are determined solely by their boundary values. We also point out that higher-derivative gravity systems give rise to new multicritical points in the parameter space of the boundary field theories.

description: Die Bachelorarbeit untersucht die literarischen Weiblichkeitsbilder in europäischen Opern des 19. und 20. Jahrhunderts im Kontext ihrer zeitgenössischen Inszenierungen. Im Vordergrund steht die Frage nach der Relevanz dieser Inszenierungen im Umgang mit traditionellen, männlich-patriarchal geprägten weiblichen Rollenbildern. Dabei werden literarische Figuren wie die Femme Fatale, Femme Fragile und Femme Enfant sowie Beispiele für deren Vertreterinnen analysiert, um die Vielfalt und Verbreitung dieser Darstellungen zu beleuchten. Die Arbeit bietet einen Beitrag zur gesellschaftlichen Debatte über Geschlechterdarstellung in der Oper und reflektiert die Rolle der Theaterpädagogik und Dramaturgie in diesem Kontext. Als exemplarisches Fallbeispiel dient die Inszenierung von „Madama Butterfly“ am Anhaltischen Theater Dessau 2023, um den Umgang mit literarischen Weiblichkeitsbildern in modernen Aufführungen zu untersuchen und kritisch zu reflektieren. Es wurde gezeigt, dass die Typen der literarischen Weiblichkeitsdarstellung nicht nur künstlerische Archetypen sind, sondern tief in den patriarchalen Strukturen verwurzelt sind. Die Untersuchung betont die Notwendigkeit, traditionelle Rollenbilder kritisch zu hinterfragen und durch zeitgenössische Interpretationen zu ersetzen. Die Arbeit plädiert dafür, dass sich die Oper als dynamische Kunstform den gesellschaftlichen Veränderungen anpassen und aktiv reflektieren muss, um ihre Relevanz zu bewahren. Sie hebt die Bedeutung der Theaterpädagogik und Dramaturgie hervor, um die Oper als inspirierendes und relevantes Medium weiterzuentwickeln. Die Zukunft der Oper hängt davon ab, wie sie traditionelle Sichtweisen überwindet und neue Perspektiven integriert, um eine breitere gesellschaftliche Debatte zu fördern und ein diverses Publikum anzusprechen.
Map-making methods for Cosmic Microwave Background experiments

Subjects: subject: Astrophysics (astro-ph)

description: The map-making step of Cosmic Microwave Background data analysis involves linear inversion problems which cannot be performed by a brute force approach for the large timelines of today. We present in this article optimal vector-only map-making methods, which are an iterative COBE method, a Wiener direct filter and a Wiener iterative method. We apply these methods on diverse simulated data, and we show that they produce very well restored maps, by removing nearly completely the correlated noise which appears as intense stripes on the simply pixel-averaged maps. The COBE iterative method can be applied to any signals, assuming the stationarity of the noise in the timeline. The Wiener methods assume both the stationarity of the noise and the sky, which is the case for CMB-only data. We apply the methods to Galactic signals too, and test them on balloon-borne experiment strategies and on a satellite whole sky survey.

description: Diese Bachelorarbeit befasst sich mit der komplexen Thematik des Zwangskontextes innerhalb der Sozialen Arbeit sowie der Bedeutung des Tripelmandates für diese. Die Auseinandersetzung damit ist für SozialarbeiterInnen von hoher Priorität, da Zwang in vielen Arbeitsfeldern angewandt wird und die Forderungen von Institutionen, der KlientInnen und ihrer Profession ständig präsent sind. Die Fragestellung zur Bearbeitung dieses Themas lautet: Inwiefern ist die Beratung im Zwangskontext trotz der Konsequenzen des Tripelmandates für die Soziale Arbeit möglich? Es erfolgt ein Einblick in die geschichtliche Entwicklung der Sozialen Arbeit, damit die Institutionalisierung von Hilfeleistungen sowie die Entstehung des Tripelmandates verständlich erklärt werden kann. Zudem werden, durch die Verwendung von Fachliteratur, mehrere Konflikte innerhalb dessen herausgearbeitet. Durch Anwendungsbeispiele in der Praxis sowie lösungsorientierte Ansätze wird dargelegt, dass die Beratung im Zwangskontext trotz der Konsequenzen des Tripelmandates unter bestimmten Bedingungen gelingen kann.

SSSpaNG! Stellar Spectra as Sparse, data-driven, Non-Gaussian processes

description: Upcoming million-star spectroscopic surveys have the potential to revolutionize our view of the formation and chemical evolution of the Milky Way. Realizing this potential requires automated approaches to optimize estimates of stellar properties, such as chemical element abundances, from the spectra. The volume and quality of the observations strongly motivate that these approaches should be data-driven. With this in mind, we introduce SSSpaNG: a data-driven non-Gaussian Process model of stellar spectra. We demonstrate the capabilities of SSSpaNG using a sample of APOGEE red clump stars, whose model parameters we infer via Gibbs sampling. Pooling information between stars to infer their covariance, we permit clear identification of the correlations between spectral pixels. Harnessing these correlations, we infer the true spectrum of each star, inpainting missing regions and denoising by a factor of at least 2 for stars with signal-to-noise of ~20. As we marginalize over the covariance matrix of the spectra, the effective prior on these true spectra is non-Gaussian and sparsifying, favouring typically small but occasionally large excursions from the mean. The high-fidelity inferred spectra produced will enable improved elemental abundance measurements for individual stars. Our model also allows us to quantify the information gained by observing portions of a star's spectrum, and thereby define the most mutually informative spectral regions. Using 25 windows centred on elemental absorption lines, we demonstrate that the iron-peak and alpha-process elements are particularly mutually informative for these spectra, and that the majority of information about a target window is contained in the 10-or-so most informative windows. Such mutual-information estimates have the potential to inform models of nucleosynthetic yields and the design of future observations.

description: We investigated the economic dynamics of the German hog-price cycle with an innovative ‘diagnostic’ modeling approach. Hog-price cycles are conventionally modeled stochastically—most recently as randomly-shifting sinusoidal oscillations. Alternatively, we applied Nonlinear Time Series analysis to empirically reconstruct a deterministic, low-dimensional, and nonlinear attractor from observed hog prices. We next formulated a structural (explanatory) model of the pork industry to synthesize the empirical hog-price attractor. Model simulations demonstrate that low price-elasticity of demand contributes to aperiodic price cycling – a well know result – and further reveal two other important driving factors: investment irreversibility (caused by high specificity of technology), and liquidity-driven investment behavior of German farmers.
Coronal cooling as a result of mixing by the nonlinear Kelvin--Helmholtz instability

description: Recent observations show cool, oscillating prominence threads fading when observed in cool spectral lines and appearing in warm spectral lines. A proposed mechanism to explain this evolution is that the threads were heated by turbulence driven by the Kelvin--Helmholtz instability that developed as a result of wave-driven shear flows on the surface of the thread. As the Kelvin--Helmholtz instability is an instability that works to mix the fluids, in the solar corona it can be expected to work by mixing the cool prominence material with that of the hot corona to form a warm boundary layer. In this paper we develop a simple phenomenological model of nonlinear Kelvin--Helmholtz mixing, using it to determine the characteristic density and temperature of the mixing layer, which for the case under study with constant pressure across the two fluids are $ρ_{\rm mixed}=\sqrt{ρ_1ρ_2}$ and $T_{\rm mixed}=\sqrt{T_1T_2}$. One result from the model is that it provides an accurate, as determined by comparison with simulation results, determination of the kinetic energy in the mean velocity field. A consequence of this is that the magnitude of turbulence, and with it the energy that can be dissipated on fast time-scales, as driven by this instability can be determined. For the prominence-corona system, the mean temperature rise possible from turbulent heating is estimated to be less than 1\% of the characteristic temperature (which is found to be $10^5$\,K). These results highlight that mixing, and not heating, are likely to be the cause of the observed transition between cool to warm material in Okamoto et. al (2015). One consequence of this result is that the mixing creates a region with higher radiative loss rates on average than either of the original fluids, meaning that this instability could contribute a net loss of thermal energy from the corona, i.e. coronal cooling.

description: This paper shows how job search success, measured as search duration and entry salary, is affected directly or indirectly by personal and process as well as structural characteristics. A specific focus is on the relevance of practical experience which is claimed to be a key feature of employability. While self-assessed practical and namely international experience is positively related to salary, but not to search duration, the number and duration of internships does not affect job search success. Results are relevant for higher education institutions to develop their curricula, for students to prepare for job search, and for employers to understand the genesis of employability and their potential means to impact it.
