description: Science, technology, engineering, and mathematics (STEM) occupations and care work occupations are highly segregated by gender. School textbooks play an essential socializing role in determining which occupations are perceived as typically male or female. Existing research on the gender representation of STEM and care work occupations in textbooks is limited in scope. Therefore, we used quantitative text analyses in a large sample of 202 current German textbooks to examine the gender representation of STEM and care work occupations. We used collocation analysis to explore the nature of the occupational representations, focusing on agency and communion. Men were portrayed significantly more frequently than women in STEM and care work occupations. Adjectives of agency and communion occurred rarely in the collocations. Further research is required to test our findings in other cultures and to take a more differentiated look into the use of agency and communion in textbooks.

description: The spectroscopic performance of x-ray instruments can be affected at high count rates. The effects and mitigation in the optical chain, such as x-ray attenuation filters or de-focusing mirrors, are widely discussed, but those in the signal chain are not. Using the Resolve x-ray microcalorimeter onboard the XRISM satellite, we discuss the effects observed during high count rate measurements and how these can be modeled. We focus on three instrumental effects that impact performance at high count rate: CPU limit, pile up, and electrical cross talk. High count rate data were obtained during ground testing using the flight model instrument and a calibration x-ray source. A simulated observation of GX 13+1 is presented to illustrate how to estimate these effects based on these models for observation planning. The impact of these effects on high count rate observations is discussed.

Year: 2025

description: We report on an all-solid-state light source for nanosecond (ns) laser pulses, with broad tunability in the mid-infrared, spectral bandwidth close to the Fourier transform limit, and pulse energy in the mJ regime. To this end, we extend a tunable, continuous wave (cw) singly resonant optical parametric oscillator by an optical parametric pre-amplifier with a periodically poled lithium niobate crystal and a power amplifier stage with two bulk lithium niobate crystals. We demonstrate pulse energies beyond 1 mJ in a tuning range between 3.3 and 3.8 μm center wavelength, with options for even larger output pulse energy and tuning range. The total conversion efficiency in the power amplifier reaches 20%. From measurements of absorption spectroscopy, we determine a very narrow linewidth of 108 MHz (full width at half maximum, FWHM), which is only a factor of 1.4 above the Fourier limit. We demonstrate the applicability and versatility of the laser system for nonlinear spectroscopy by resonantly enhanced third harmonic generation and sum frequency mixing in a gas sample of HCl molecules.

description: Autonomous agents rely on sensor data to construct representations of their environments, essential for predicting future events and planning their actions. However, sensor measurements suffer from limited range, occlusions, and sensor noise. These challenges become more evident in highly dynamic environments. This work proposes a probabilistic framework to jointly infer which parts of an environment are statically and which parts are dynamically occupied. We formulate the problem as a Bayesian network and introduce minimal assumptions that significantly reduce the complexity of the problem. Based on those, we derive Transitional Grid Maps (TGMs), an efficient analytical solution. Using real data, we demonstrate how this approach produces better maps by keeping track of both static and dynamic elements and, as a side effect, can help improve existing SLAM algorithms.

Wake forces in a background of quadratically coupled mediators
Creators: name: Van Tilburg, Ken
Publisher: name: arXiv
Year: 2024
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Two particles can exert forces on each other when embedded in a sea of weakly-coupled particles. These "wake forces'' occur whenever the source and target particles have quadratic interactions with the mediating particles; they are proportional to the ambient energy density, and typically have a range of order the characteristic de Broglie wavelength of the background. The effect can be understood as source particles causing a disturbance in the background waves -- a wake -- which subsequently interacts with the target particles. Wake forces can be mediated by bosons or fermions, can have spin dependence, may be attractive or repulsive, and have a generally anisotropic spatial profile and range that depends on the phase-space distribution of the ambient particles. In this work, I investigate the application of wake forces to dark matter searches, recast existing limits on short-range forces into leading constraints on dark matter with quadratic couplings, and sketch out potential experimental modifications to optimize sensitivity. Wake forces occur in the Standard Model: the presence of the cosmic neutrino background induces a millimeter-range force about 22 orders of magnitude weaker than gravity. Wake forces may also be relevant in condensed-matter and atomic physics.

Andrena callopyrrha Cockerell, 1929a: 205, ♀ [China: Shandong, NHMUK, lectotype by present designation] (Figures 29A– D)
Remarks. Cockerell (1929a) described this species from China, mentioning four female specimens collected on April 7 th [1928]. Xu & Tadauchi (1997) indicate that they examined the “ holotype ” female at the USNM, and indeed the label of the USNM specimen is labelled as “Type” by Cockerell. However, this does not make it the holotype, because Cockerell never stated in the original publication that one specific specimen was the holotype as is required under Article 73.1.1 (ICZN 1999). Cockerell (1929a: 206) simply writes “Tsinan, China, 4♀, April 7 th (Jacot)”. Of the four female specimens, they are all syntypes and could all be designated as lectotypes. Examination of the NHMUK collection located a specimen marked as A. callopyrrha with Cockerell’s distinctive handwriting, collected in April [19]28 by Jacot. This specimen conforms to the type concept, and is hereby designated as a lectotype for consistency with the type depository suggested by Gusenleitner & Schwarz (2002).
Distribution. Russia (Western Siberia), Kazakhstan, Mongolia, China (Beijing, Shandong, Jiangsu, Shannxi, Inner Mongolia) (Xu & Tadauchi 2003; Proshchalykin et al. 2017).

description: Dusty plasma is an admixture of electrons, ions, and massive charged solid particles of sub-micron to micron-sized in the background of neutral gas. The dust grain medium exhibits fluid (liquid) as well as solid-like characteristics at different background plasma conditions. It supports various linear and non-linear dynamical structures because of the external perturbation and internal instabilities. The vortical or coherent structure in the dusty plasma medium is a kind of self-sustained dynamical structure that is formed either by instabilities or external forcing. In this review article, the author discusses the past theoretical, experimental, and computational investigations on vortical and coherent structures in unmagnetized as well as in magnetized dusty plasma. The possible mechanisms to form vortices in dust grain medium are discussed in detail. The studies on the evolution of vortices and their correlation with turbulence are also reviewed.

description: Multidimensional item response theory (MIRT) models have generated increasing interest in the psychometrics literature. Efficient approaches for estimating MIRT models with dichotomous responses have been developed, but constructing an equally efficient and robust algorithm for polytomous models has received limited attention. To address this gap, this paper presents a novel Gaussian variational estimation algorithm for the multidimensional generalized partial credit model (MGPCM). The proposed algorithm demonstrates both fast and accurate performance, as illustrated through a series of simulation studies and two real data analyses.

description: Active particle systems of interacting self-propelled particles offer a versatile framework for modeling complex systems. When employed to describe aspects of animal behavior, the complexity of animal movement and decision-making often requires the use of unique types of effective interactions between the particles -- notably nonreciprocal effective forces that do not obey the usual conservation laws of Newtonian mechanics. Here we review two recent empirically-motivated models, of two very different types of animal behavior, where the behavior is described in terms of active particles which interact through nonreciprocal effective forces. The first model describes the dynamics of animal contests, wherein typically two rivals fight over a localized resource. The uniquely shaped effective potentials between the model's 'contestant particles' manifest the adversarial nature of contest interactions and capture the dynamical essence of contest behavior in space and time. The second model describes the stabilization of cohesive swarms through long-range and adaptive gravity-like attraction. This 'adaptive gravity' model explains the observed mass and velocity profiles of laboratory midge swarms. These examples demonstrate that theoretical models that use the framework of active particles to describe animal behavior can expand the scope of active-particle research, as well as explain complex phenomena in animal behavior.

Andrena nigriceps ssp. pamirensis Alfken, 1931: 827, ♀ ♂ [Tajikistan, ZMHB, examined] syn. nov. (Figures 31A–D)
Remarks. The subgenus Cnemidandrena Hedicke, 1933 is taxonomically challenging, even in Europe. Alfken (1931) described a subspecies of A. nigriceps (Kirby, 1802), a species that is widespread in temperate parts of the West Palaearctic. Examination of the type material of A. nigriceps ssp. pamirensis shows that it is conspecific with A. jagnobensis (illustrated in Astafurova et al. 2021); both taxa were described from Tajikistan. If the suspected type localities are correct, then the two taxa were described from within 100 km of each other. Alfken (1936: 827) even reports three females and two males of A. jagnobensis from the same place and day! Andrena jagnobensis can be separated from A. nigriceps due to the polished and shining clypeus, with clear shining interspaces between clypeal punctures (Figure 31C). The type specimen of A. nigriceps ssp. pamirensis simply represents an individual with darker than average pubescence relative to typical A. jagnobensis (Figure 31D). True A. nigriceps is unknown from Central Asia, and hence A. nigriceps ssp. pamirensis is synonymised syn. nov. with A. jagnobensis. More broadly, since Gusenleitner & Schwarz (2002) list A. jagnobensis as a junior synonym of A. nigriceps, the works of Osytshnjuk et al. (2005) and Astafurova et al. (2021) can be used to justify the species-status of A. jagnobensis.

We further discuss different criteria for introducing boundary terms in some familiar first-order gravity theories with both on-shell vanishing and non-vanishing torsion, along with considerations regarding the thermodynamics of black holes and profiles of the End-of-the-World branes. Our analysis confirms the expected geodesic profile of the End-of-the-World brane in the BF formulation of Jackiw-Teitelboim gravity. Finally, we present the first realisation of the AdS/BCFT duality for spacetime with torsion.

Andrena cussariensis kohatensis Cockerell, 1917: 283, ♀ [Pakistan, USNM, photograph examined] syn. nov.
Remarks. Andrena fuscosa is a widespread and highly variable species found in both the West and Central Palaearctic to northern India. Genetically, specimens from northern India differ in their COI barcode sequence by only around 1% from specimens from Spain, the locus typicus (Wood 2023b). Due to high morphological variation, many synonyms have been described (e.g. Gusenleitner & Schwarz 2002; Wood 2023c), but a broad interpretation is currently followed (Wood 2023b).
Cockerell (1917) described new species from British India, from what is now modern Pakistan. Among these was A. cussariensis kohatensis that Cockerell indicated (based only on the description) was close to A. (Melandrena) cussariensis Morawitz, 1886, but closer to A. ephippium Spinola, 1838 (= A. fuscosa, see Wood 2023c). For reasons unknown, he described Pakistani material as A. cussariensis kohatensis. Examination of type photographs shows that A. cussariensis kohatensis is clearly a junior synonym of A. fuscosa due to the presence of a rugose-areolate propodeal triangle (hence clearly not part of the subgenus Melandrena Pérez, 1890), ovoid and densely punctate metasoma, dark integument with partial red markings on the scutum and scutellum, dark infuscate wings, and short tight scopal hairs. The specimen in the USNM is likely automatically the holotype since Cockerell only described the female, and did not indicate that there were additional specimens. There are no confirmed records of true A. (Melandrena) cussariensis from Pakistan, with a current south-eastern range limit in northern Iran and Central Asia (Wood & Monfared 2022).
Material examined. SPAIN: Andalucia, [undated], 1♂, ZMHB (holotype/ syntype); PAKISTAN: Kohat, Mch’ 06 [iii.1906], 1♀, leg. F. Benton, USNM (holotype/ syntype of A. cussariensis kohatensis; type no. 23135, examined by photograph).
Distribution. West Palaearctic, Central Asia, Pakistan, and India (Gusenleitner & Schwarz 2002; Osytshnjuk et al. 2008; Wood 2023b).

description: Material challenges are the key issue in Majorana research where surface disorder constrains device performance. Here, we tackle this challenge by embedding PbTe nanowires within a lattice-constant-matched crystal. The wire edges are shaped by self-organized growth instead of lithography, resulting in nearly-atomic-flat facets along both cross-sectional and longitudinal directions. Quantized conductance is observed at zero magnetic field with channel lengths maximally reaching 1.7 $μ$m, significantly surpassing the state-of-the-art of III-V nanowires (an order-of-magnitude improvement compared to InSb). Coupling PbTe to a Pb film unveils a flat interface spanning microns and a large superconducting gap of 1 meV. Our result not only represents a stride toward meeting the stringent low-disorder requirement for Majoranas, but may also open the door to various hybrid quantum devices requiring a low level of disorder.

description: Reforming social security can improve efficiency and reduce future fiscal strain, emerging with the rising old-age longevity. However, it generates transitory fiscal cost and reduces insurance against income risk, which is embedded in current US social security. We show that if that transitory fiscal cost is financed through increased capital income taxation, the efficiency gains can be amplified sufficiently to outweigh the costs of the reform. Our result stems from the Ramsey rule: rising old-age longevity makes capital less responsive to tax hikes. We reconcile our results with the existing literature. Our results are of policy relevance for many advanced economies which currently feature redistributive and increasingly unbalanced social security due to rising old-age longevity.

description: Plasma membrane localized anoctamin 1, 2 and 6 (TMEM16A, B, F) have been examined in great detail with
respect to structure and function, but much less is known about the other seven intracellular members of this
exciting family of proteins. This is probably due to their limited accessibility in intracellular membranous
compartments, such as the endoplasmic reticulum (ER) or endosomes. However, these so-called intracellular
anoctamins are also found in the plasma membrane (PM) which adds to the confusion regarding their cellular
role. Probably all intracellular anoctamins except of ANO8 operate as intracellular phospholipid (PL) scramblases,
allowing for Ca2+-activated, passive transport of phospholipids like phosphatidylserine between both
membrane leaflets. Probably all of them also conduct ions, which is probably part of their physiological function.
In this brief overview, we summarize key findings on the biological functions of ANO3, 4, 5, 7, 8, 9 and 10
(TMEM16C, D, E, G, H, J, K) that are gradually coming to light. Compartmentalized regulation of intracellular
Ca2+ signals, tethering of the ER to specific PM contact sites, and control of intracellular vesicular trafficking
appear to be some of the functions of intracellular anoctamins, while loss of function and abnormal expression
are the cause for various diseases.

Generalization Bounds for Heavy-Tailed SDEs through the Fractional Fokker-Planck Equation

description: Understanding the generalization properties of heavy-tailed stochastic optimization algorithms has attracted increasing attention over the past years. While illuminating interesting aspects of stochastic optimizers by using heavy-tailed stochastic differential equations as proxies, prior works either provided expected generalization bounds, or introduced non-computable information theoretic terms. Addressing these drawbacks, in this work, we prove high-probability generalization bounds for heavy-tailed SDEs which do not contain any nontrivial information theoretic terms. To achieve this goal, we develop new proof techniques based on estimating the entropy flows associated with the so-called fractional Fokker-Planck equation (a partial differential equation that governs the evolution of the distribution of the corresponding heavy-tailed SDE). In addition to obtaining high-probability bounds, we show that our bounds have a better dependence on the dimension of parameters as compared to prior art. Our results further identify a phase transition phenomenon, which suggests that heavy tails can be either beneficial or harmful depending on the problem structure. We support our theory with experiments conducted in a variety of settings.
