description: The gender gap in computer science (CS) research is a well-studied problem, with an estimated ratio of 15%--30% women researchers. However, far less is known about gender representation in specific fields within CS. Here, we investigate the gender gap in one large field, computer systems. To this end, we combined data from 53 leading systems conferences with external demographic and bibliometric data to evaluate the ratio of women authors and the factors that might affect this ratio. Our main findings are that women represent only about 10% of systems researchers, and that this ratio is not associated with various conference factors such as size, prestige, double-blind reviewing, and inclusivity policies. Author research experience also does not significantly affect this ratio, although author country and work sector do. The 10% ratio of women authors is significantly lower than that of CS as a whole. Our findings suggest that focusing on inclusivity policies alone cannot address this large gap. Increasing women's participation in systems research will require addressing the systemic causes of their exclusion, which are even more pronounced in systems than in the rest of CS.

description: Microwave loss in niobium metallic structures used for superconducting quantum circuits is limited by a native surface oxide layer formed over a timescale of minutes when exposed to an ambient environment. In this work, we show that nitrogen plasma treatment forms a niobium nitride layer at the metal-air interface which prevents such oxidation. X-ray photoelectron spectroscopy confirms the doping of nitrogen more than 5 nm into the surface and a suppressed oxygen presence. This passivation remains stable after aging for 15 days in an ambient environment. Cryogenic microwave characterization shows an average filling factor adjusted two-level-system loss tangent $\rm{Fδ_{TLS}}$ of $(2.9\pm0.5)\cdot10^{-7}$ for resonators with 3 $\rmμ$m center strip and $(1.0\pm0.3)\cdot10^{-7}$ for 20 $\rmμ$m center strip, exceeding the performance of unpassivated samples by a factor of four.

description: In recent years, three deposits of grinding stones have been discovered in Central Germany, resembling a phenomenon known from the Paris Basin and Belgium. These deposits were more than simple disposals; they likely held ritual or symbolic significance, reflecting the values and beliefs of the community. Their symbolism is diverse, shaped by both the tools themselves and their locations. The condition of the tools—ranging from new to nearly worn-out—adds layers of meaning, suggesting cycles of creation, use, and obsolescence. These symbols, such as fertility, life cycles, and territorial markers, mirror the daily and yearly rhythms of agrarian life. Additionally, they represent human biographies and social relationships, often emphasizing transitional moments such as birth, marriage, and death. A techno-functional analysis of the grinding tools highlights time as a central theme, symbolized through daily routines, seasonal cycles, and human lifespans. Overall, these interpretations reveal the complex and multifaceted nature of the grinding stone deposits, offering valuable insights into the worldviews and practices of past societies.

description: In many emerging countries the TVET system has been implemented in order to qualify young people for the world of work and to leave poverty behind. In many of these countries TVET success stories from Europe are told. However, in most of the emerging countries TVET has not gained momentum yet - as expected. This research will tighten the investigation on 5 factors which will be compared between the TVET system in German speaking countries and developing/emerging countries – represented by Ethiopia. The selected factors are the purpose assigned to the TVET system, the structure of the TVET system, the innovation approach and entrepreneurship education as well as the preconditions to become a TVET teacher/instructor. The analysis of these factors should demonstrate a disaggregated perspective the TVET success stories told from the German speaking countries.
Monte Carlo Simulation of Dust Particles in a Protoplanetary Disk: Crystalline to Amorphous Silicate Ratio in Comets

description: Observationally inferred crystalline abundance in silicates in comets, which should have been formed in the outer region of a protoplanetary disk, is relatively high (~ 10-60%), although crystalline silicates would be formed by annealing of amorphous precursors in the disk inner region. In order to quantitatively address this puzzle, we have performed Monte Carlo simulation of advection/diffusion of silicate particles in a turbulent disk, in the setting based on pebble accretion model: pebbles consisting of many small amorphous silicates embedded in icy mantle are formed in the disk outer region, silicate particles are released at the snow line, crystalline silicate particles are produced at the annealing line, the silicate particles diffused beyond the snow line, and they eventually stick to drifting pebbles to come back to the snow line. In a simple case without the sticking and with a steady pebble flux, we show through the simulations and analytical arguments that crystalline components in silicate materials beyond the snow line is robustly and uniformly ~ 5%. On the other hand, in a more realistic case with the sticking and with a decaying pebble flux, the crystalline abundance is raised up to ~ 20-25%, depending on the ratio of decay and diffusion timescales. This abundance is consistent with the observations. In this investigation, we assume a simple steady accretion disk. The simulations coupled with the disk evolution is needed for more detailed comparison with observed data.

description: Online advertising is a major source of income for many online companies. One common approach is to sell online advertisements via waterfall auctions, through which a publisher makes sequential price offers to ad networks. The publisher controls the order and prices of the waterfall in an attempt to maximize his revenue. In this work, we propose a methodology to learn a waterfall strategy from historical data by wisely searching in the space of possible waterfalls and selecting the one leading to the highest revenues. The contribution of this work is twofold; First, we propose a novel method to estimate the valuation distribution of each user, with respect to each ad network. Second, we utilize the valuation matrix to score our candidate waterfalls as part of a procedure that iteratively searches in local neighborhoods. Our framework guarantees that the waterfall revenue improves between iterations ultimately converging into a local optimum. Real-world demonstrations are provided to show that the proposed method improves the total revenue of real-world waterfalls, as compared to manual expert optimization. Finally, the code and the data are available here.

description: Background: Inherited retinal degenerations are a major cause of untreatable blindness in the younger age group. Recent advances in gene therapy using adeno-associated viral (AAV) vectors have raised the possibility of slowing or stopping retinal degenerations with gene replacement in cases of gene deficiency. Materials and methods: In this report, we present a family with autosomal dominant retinitis pigmentosa. A screen for common ADRP genes was performed with 105 genes targeted. Next generation sequencing was used to identify the mutation which was next confirmed by bidirectional Sanger sequencing. Results: A novel mutation of the TOPORS gene was identified, c.2539C>T p.(Arg847Ter), resulting in a premature termination codon and suggesting haploinsufficiency as the pathological mechanism. Conclusions: Since the cDNA encoding TOPORS is 3,135 nucleotides (within the coding capacity of AAV vectors) and haploinsufficiency is a mechanism relating to inadequate gene expression, gene replacement therapy may be an option for patients with this condition.

description: A gauge-invariant model is constructed for the $γp \to K^+Λ(1690)$ reaction within a tree-level effective Lagrangian approach with the purpose to understand the underlying production mechanisms and to study the resonance contributions in this reaction. In addition to the $t$-channel $K$ and $K^\ast$ exchanges, the $s$-channel nucleon exchange, and the interaction current, the $s$-channel nucleon resonance exchanges are also included in constructing the reaction amplitudes to describe the data. It is found that the contributions from the $s$-channel $N(2570)5/2^-$ exchange are required to describe the most recently measured total cross-section data for $γp \to K^+Λ(1690)$ from the CLAS Collaboration. Further analysis shows that the interaction current dominates the $γp \to K^+Λ(1690)$ reaction near the threshold as a result of gauge invariance. The $t$-channel $K$ exchange contributes significantly, while the contributions from the $t$-channel $K^\ast$ exchange as well as the $s$-channel nucleon exchange turn out to be negligible. The contributions from the $s$-channel $N(2570)5/2^-$ exchange are found to be responsible for the bump structure shown in the CLAS total cross-section data above the center-of-mass energy $W \approx 2.7$ GeV. The predictions of the differential cross sections for $γp \to K^+Λ(1690)$ are shown and discussed, which can provide theoretical guidances for the future experiments.

description: This report presents an overview of relevant non-technical and legal challenges for consideration during the deployment of a pay-per-wash business model in four European countries (Netherlands, Slovenia, Denmark and Austria). Three categories of barriers are derived from a literature study: Policy, Economic and Market. Furthermore, legislative background to the project is discussed based on academic papers and European legislation. Finally, a snapshot of operational challenges in relation to the deployment of the pay-per-wash business models are presented based on primary data. Key questions for the white goods demonstrator Gorenje are juxtaposed with the experience of the supporting startup HOMIE. While several challenges are discovered, no major obstacles to project success are identified.

description: Mn-based superconductor is rare and recently reported in quasi-one-dimensional KMn$_6$Bi$_5$ with [Mn$_6$Bi$_5$]-columns under high pressure. Here we report the synthesis, magnetic properties, electrical resistivity, and specific heat capacity of the newly-discovered quasi-one-dimensional NaMn$_6$Bi$_5$ single crystal. Compared with other AMn$_6$Bi$_5$ (A = K, Rb, and Cs), NaMn$_6$Bi$_5$ has larger intra-column Bi-Bi bond length, which may result in the two decoupled antiferromagnetic transitions at 47.3 K and 52.3 K. The relatively lower antiferromagnetic transition temperatures make NaMn$_6$Bi$_5$ a more suitable platform to explore Mn-based superconductors. Anisotropic resistivity and non-Fermi liquid behavior at low temperature are observed. Heat capacity measurement reveals that NaMn$_6$Bi$_5$ has similar Debye temperature with those of AMn$_6$Bi$_5$ (A = K and Rb), whereas the Sommerfeld coefficient is unusually large. Using first-principles calculations, the quite different density of states and an unusual enhancement near the Fermi level are observed for NaMn$_6$Bi$_5$, when compared with those of other AMn$_6$Bi$_5$ (A = K, Rb, and Cs) compounds.

description: Eight new (porphyrinato)(naphthalocyaninato) rare earth(III) double-decker complexes MIII(TONPP)[Nc(PhS)8] [M = La, Pr, Nd, Sm, Eu, Gd, Tb, and Dy; TONPP = 5,10,15,20-tetrakis(4-octyloxynaphthyl) porphyrin; Nc(PhS)8 = 3,4,12,13,21,22,30,31-octa(phenylthio)-2,3-naphthalocyanine] have been prepared and characterized by spectroscopic methods. The UV–vis absorption spectra depend on the central rare earth ionic size, suggesting that all the transitions involve molecular orbitals with contribution from both porphyrin and naphthalocyanine ligands. The IR and Raman spectra of these double-decker compounds were systemically investigated, showing that the electron hole in these mixed double-deckers is mainly localized at the naphthalocyanine ring. Their sandwich nature was also characterized by MS, EA, and 1H NMR techniques.

description: Analogue gravity systems offer many insights into gravitational phenomena, both at the classical and at the semiclassical level. The existence of an underlying Minkowskian structure (or Galilean in the non-relativistic limit) in the laboratory has been argued to directly forbid the simulation of geometries with Closed Timelike Curves (CTCs) within analogue systems. We will show that this is not strictly the case. In principle, it is possible to simulate spacetimes with CTCs whenever this does not entail the presence of a chronological horizon separating regions with CTCs from regions that do not have CTCs. We find an Analogue-gravity Chronology protection mechanism very similar in spirit to Hawking's Chronology Protection hypothesis. We identify the universal behaviour of analogue systems near the formation of such horizons and discuss the further implications that this analysis has from an emergent gravity perspective. Furthermore, we build explicit geometries containing CTCs, for instance spacetimes constructed from two warp-drive configurations, that might be useful for future analysis, both from a theoretical and an experimental point of view.

description: The special issue summarises and highlights key findings of the research unit DASIM funded by the German Research Foundation (DFG) on the process of denitrification. Progress was made in several areas including the development of new and advanced methods to quantify N2 fluxes such as a new 15N gas flux method, enhanced Raman spectroscopy and a new incubation system to study plant-soil interactions in He-O2 atmosphere. Understanding of denitrification in disturbed and structured soil was gained by combining X-ray CT scanning and microbial ecology methods. High resolution models developed as part of DASIM were able to successfully simulate experimental data and provide valuable insights for the improvement of existing ecosystem models. Improved 15N tracing tools for the analysis of 15N tracing data in soil-plant systems have been developed that are extensively used by associated partners. DASIM brought together an interdisciplinary network of researchers interested in analytical but also modelling aspects. This includes close collaboration with the FAO/IAEA centre of Nuclear Techniques in Food and Agriculture of the United Nations which resulted in an open access book that describes the methods used in DASIM. The impact of the DASIM research unit on the scientific community is manifold and will most likely have a lasting impact on the understanding of nitrogen cycling in terrestrial ecosystems.

Investigate how often participants from the condition "Einstellung with critical trials" choose the Einstellung solution in the critical trials and compare these numbers for thinking aloud vs. silent thinking (e.g., chi square, logistic regression). From the coded verbal protocols: identify if subjects of the non-Einstellung control group show the direct solution more often as a first attempt and take less solution attempts than subjects of the Einstellung condition.

description: Topological defects are at the root of the large-scale organization of liquid crystals. In two-dimensional active nematics, two classes of topological defects of charges $\pm 1/2$ are known to play a major role due to active stresses. Despite this importance, few analytical results have been obtained on the flow-field and active-stress patterns around active topological defects. Using the generic hydrodynamic theory of active systems, we investigate the flow and stress patterns around these topological defects in unbounded, two-dimensional active nematics. Under generic assumptions, we derive analytically the spontaneous velocity and stall force of self-advected defects in the presence of both shear and rotational viscosities. Applying our formalism to the dynamics of monolayers of elongated cells at confluence, we show that the non-conservation of cell number generically increases the self-advection velocity and could provide an explanation for their observed role in cellular extrusion and multilayering. We finally investigate numerically the influence of the Ericksen stress. Our work paves the way to a generic study of the role of topological defects in active nematics, and in particular in monolayers of elongated cells.

description: Social media influence online activity by recommending to users content strongly correlated with what they have preferred in the past. In this way they constrain users within filter bubbles that strongly limit their exposure to new or alternative content. We investigate this type of dynamics by considering a multistate voter model where, with a given probability $λ$, a user interacts with a "personalized information" suggesting the opinion most frequently held in the past. By means of theoretical arguments and numerical simulations, we show the existence of a nontrivial transition between a region (for small $λ$) where consensus is reached and a region (above a threshold $λ_c$) where the system gets polarized and clusters of users with different opinions persist indefinitely. The threshold always vanishes for large system size $N$, showing that consensus becomes impossible for a large number of users. This finding opens new questions about the side effects of the widespread use of personalized recommendation algorithms.

description: Type I X-ray bursts are the result of an unstable thermonuclear burning of accreting matter on the neutron star (NS) surface. The quick release of energetic X-ray photons during such bursts interacts with the surrounding accretion disk, which raises the accretion rate due to Poynting-Robertson drag and, thus, a fraction of the burst emission is reflected. We analyzed two photospheric radius expansion bursts in the NS low-mass X-ray binary 4U 1636--536 that took place in 2017, using data from Neutron star Interior Composition Explorer. The time-resolved burst spectra showed clear deviations from a blackbody model. The spectral fitting can be significantly improved by introducing either the enhanced persistent emission (the $f_a$ model) or the reflection from the accretion disk (the \texttt{relxillNS} model). The $f_a$ model provides a higher blackbody temperature and higher burst flux compared with the \texttt{relxillNS} model. The peak fluxes of two bursts from the $f_a$ model, $4.36\times10^{-8}~\mathrm{erg~cm^{-2}~s^{-1}}$ and $9.10\times10^{-8}~\mathrm{erg~cm^{-2}~s^{-1}}$, are slightly higher than the Eddington limits of mixed hydrogen-helium and pure helium bursts from previous observations, respectively. When the disk reflections have been taken into account simultaneously, the peak fluxes are lower to match the preferred values. We find evidence to support the finding that both the Poynting-Robertson drag and disk reflection have been appeared during these two X-ray bursts. Moreover, the disk reflection may contribute $\sim20-30\%$ of the total burst emissions.

Data analysis will screen for statistic outliers (Tukey criterion). Once extreme outliers are linked to misunderstandings of the instructions (as possibly noted by the experimenter), the data will be excluded, otherwise included. Mild outliers will not be excluded. Missing data due to procedure failings may be replaced if students' capacities allow for that. Exclusions which come up after the end of the testing period will not be replaced.

description: Image narrative generation is a task to create a story from an image with a subjective viewpoint. Given the importance of the subjective feelings of writers, readers, and characters in storytelling, an image narrative generation method should consider human emotion. In this study, we propose a novel method of image narrative generation called ViNTER (Visual Narrative Transformer with Emotion arc Representation), which takes "emotion arc" as input to capture a sequence of emotional changes. Since emotion arcs represent the trajectory of emotional change, it is expected that we can include detailed information about the emotional changes in the story to the model. We present experimental results of both automatic and manual evaluations on the Image Narrative dataset and demonstrate the effectiveness of the proposed approach.

description: Bacterial behavior in oil–water biphasic systems plays an essential role in hydrophobic contaminant degradation, oil recovery, and emulsion breaking. Less is known about the cell surface properties that govern their behaviors in oil–water biphasic systems. In this study, biphasic partitioning and aggregation of a demulsifying strain of Alcaligenes sp. S-XJ-1 were experimentally measured and evaluated based on the cell surface properties of surface charge, surface free energy, and cell surface hydrophobicity (CSH). The S-XJ-1 was cultivated with five different carbon sources, and the results showed a highly varied partitioning, aggregation behavior, and cell surface properties. The calculated interaction energies, based on the cell surface properties, were consistent with the results of their behavior. Among the cell surface properties, the electron-donor character (γ−, range 8.8–57.0 mJ/m2), which correlated well with CSH (ΔGbwb), was an essential indicator of cell behavior. A low γ− value enhanced the cell–interface and cell–cell interaction energies, which promoted cell partitioning and aggregation eventually leading to demulsification. The results and analysis provide important information for researchers concerned with cell–cell and cell–interface interactions.

description: We have used small-angle neutron scattering to determine the vortex lattice phase diagram in the topological superconductor UPt3 for the applied magnetic field along the crystalline c-axis. A triangular vortex lattice is observed throughout the superconducting state, but with an orientation relative to the hexagonal basal place that changes with field and temperature. At low temperature, in the chiral B phase, the vortex lattice undergoes a non-monotonic rotation with increasing magnetic field. The rotation amplitude decreases with increasing temperature and vanishes before reaching the A phase. Within the A phase an abrupt +/-15 degree vortex lattice rotation was previously reported by Huxley et al., Nature 406, 160-164 (2000). The complex phase diagram may be understood from competing effects of the superconducting order parameter, the symmetry breaking field, and the Fermi surface anisotropy. The low-temperature rotated phase, centered around 0.8 T, reported by Avers et al., Nature Physics 16, 531-535 (2020), can be attributed directly to the symmetry breaking field.

description: Flexible PLA-based antibacterial composite films were prepared using a natural oil, Liquidambar orientalis, as bio-based plasticizer, and 2D graphitic carbon nitride (g-C3N4) decorated with Ag nanoparticles with a particle size of 10–30 nm as antibacterial agent (Ag@g-C3N4). This structurally designed antibacterial nanocomposite was synthesized with the preparation of g-C3N4 by high-temperature annealing followed by the reduction of silver salt onto g-C3N4. The Ag@g-C3N4 nanocomposite exhibited a surface area value of 18 g/m2. PLA/Ag@g-C3N4 composite films were prepared with solution casting method by introducing 30 phr of L. orientalis oil and various amounts (1, 2 and 4 phr) of Ag@g-C3N4. It was found that 30 phr of L. orientalis oil successfully plasticized the PLA and reduced its glass transition temperature from 60 °C to 43 °C and its melting temperature more than 10 °C by reducing the strong interactions and hydrogen bonds between PLA chains. L. orientalis oil also acted as a dispersion agent for the Ag@g-C3N4 nanocomposite particles and significantly improved their antibacterial activity. Antibacterial tests performed using Gram-positive bacteria (Staphylococcus aureus ATCC 25923) and Gram-negative bacteria (Escherichia coli ATCC 25922 and Acinetobacter baumannii ATCC BAA 747) indicated that introducing a small amount of 2D Ag@g-C3N4 nanocomposite particles into PLA yielded superior antibacterial activity.

description: Zola è uno degli scrittori francesi più tradotti in Grecia nel XX secolo. Dopo la polemica suscitata dalla pubblicazione di Nana, le sue opere, veicolate dalla traduzione, hanno traghettato informazioni sulla cultura francese, in particolare su quella parigina, del XIX secolo. Partendo da un corpus costituito dalle traduzioni dell’Œuvre e del Bonheur des Dames, ci proponiamo di studiare gli elementi culturali che sono ampiamente descritti da Zola. Ci interesseremo più precisamente dell’immagine del milieu artistico, dell’arte, della moda e dell’architettura. Abborderemo così le scelte dei traduttori caratterizzate dai dati storici, e mostreremo l’intraducibilità di alcuni elementi che lasciano trapelare l’eterogeneità delle società di partenza e quella di arrivo. Infine presenteremo i mezzi utilizzati (prefazioni, note a piè di pagina, appendici) per favorire l’acclimatazione culturale del lettore.

description: This paper considers the problem of cost-aware downlink sum-rate maximization via joint optimal radio access technologies (RATs) assignment and power allocation in next-generation heterogeneous wireless networks (HetNets). We consider a future HetNet comprised of multi-RATs and serving multi-connectivity edge devices (EDs), and we formulate the problem as mixed-integer non-linear programming (MINP) problem. Due to the high complexity and combinatorial nature of this problem and the difficulty to solve it using conventional methods, we propose a hierarchical multi-agent deep reinforcement learning (DRL)-based framework, called DeepRAT, to solve it efficiently and learn system dynamics. In particular, the DeepRAT framework decomposes the problem into two main stages; the RATs-EDs assignment stage, which implements a single-agent Deep Q Network (DQN) algorithm, and the power allocation stage, which utilizes a multi-agent Deep Deterministic Policy Gradient (DDPG) algorithm. Using simulations, we demonstrate how the various DRL agents efficiently interact to learn system dynamics and derive the global optimal policy. Furthermore, our simulation results show that the proposed DeepRAT algorithm outperforms existing state-of-the-art heuristic approaches in terms of network utility. Finally, we quantitatively show the ability of the DeepRAT model to quickly and dynamically adapt to abrupt changes in network dynamics, such as EDs mobility.

description: Background: The aim was to summarize and discuss the current knowledge about genetic factors influencing the reduction of central corneal thickness (CCT) in disorders affecting the eye, such as primary open-angle glaucoma (POAG), brittle cornea syndrome (BCS), keratoconus (KTCN), Ehlers–Danlos syndrome (EDS; types I, II, and VI), osteogenesis imperfecta (OI), and myopia. Materials and methods: A review of the published literature by use of key databases such as PubMed was undertaken in accordance with PRISMA guidelines and experience based on own research findings was applied. Results: The differences in CCT measurements among those affected with diverse disorders and healthy individuals were evaluated. Then we considered the influence of genetic factors on CCT reduction. Disorders were compared based on phenotypes and sequence variants found in patients. Conclusions: Specific sequence variants in COL8A2, PRDM5 and ZNF469, COL5A1 and ZNF469, and COL5A1 and COL5A2 could probably contribute to a CCT reduction in POAG, BCS, KTCN, and EDS, respectively. Similar sequence variants and phenotypes were identified and assessed in more than one disease.

description: A total of 150 bacteria were isolated from the less and more altered (weathered) purple siltstones and the adjacent soils to compare the changes in the rock weathering patterns and populations of rock-weathering bacteria. The proportions of the highly effective Fe and Si solubilizers were significantly different among the altered rocks and soils. Maximum proportions of the highly effective Fe, Si, and Al solubilizers were observed in the soils, while significantly higher proportion of the highly effective K solubilizers was observed in the more altered rocks and the soils. The rock-weathering bacteria belonged to 37 bacterial species, among which 36, 64, and 56% of the species were specific to the less and more altered rocks and the soils, respectively. In the rock-weathering process, strains M78 and L38 mainly produced acetic acid, while strain H28 mainly produced gluconic acid. Furthermore, dominant rock-weathering members of Ensifer genus had the higher ability to release Fe and Si, while dominant rock-weathering members of Bacillus had the higher ability to release K. The results suggest the changes in the element mobilization patterns and populations of the rock-weathering bacteria and highlight the possible role of these bacteria in the rock weathering and soil formation.
