description: We present an exact solution for an itinerant hole added into the oxygen orbitals of a CuO$_{3}$-like ferromagnetic chain. Using the Green's function method, the quantum polarons obtained for the Heisenberg SU(2) interaction between localized Cu spins are compared with the polarons in the Ising chain. We find that magnons with large energy are favorable towards quasiparticle existence, even in the case of relatively modest electron-magnon coupling. We observe two quasiparticle states with dispersion $\sim 2t$ each, which emerge from the incoherent continuum when the exchange coupling $J$ increases. Quantum fluctuations in the spin system modify the incoherent part of the spectrum and change the spectral function qualitatively, beyond the bands derived from the perturbation theory.

description: The molecular biological field of epigenetics has recently attracted attention not only in biology, but also in the broader scientific community and the popular press. Commentators paint a very heterogeneous picture with some arguing that epigenetics is nothing but another aspect of gene regulation, and others enthusiastically proclaiming a paradigmatic shift in developmental biology. This article analyses a particular approach to environmental epigenetics – a subfield of epigenetics that is central to the recent excitement. The focus lies on an ethnographic analysis of research practices that enable a particular lab group to study the impact of different levels of context, for example, changes in the social and material environment, on epigenetic modification and thus phenotypic variation. The article argues that changes in the practice of doing epigenetic biology contribute to a molecularisation of biography and milieu, suggest the configuration of somatic sociality and produce a different concept of the body: the embedded body. This article concludes with a brief discussion of customary biology as a potential new research agenda at the interface of material and social inquiry.

description: Semi-regular variables (SRVs) though closely related to Mira variables, are a less studied class of AGB stars. While asymmetry in the brightness distribution of many Mira variables is fairly well known, it is detected only in a few SRVs. Asymmetry in the brightness distribution at the level of a few milliarcsecond (mas) can be detected by high angular resolution techniques like lunar occultations (LO), long baseline interferometry, and aperture masking interferometry. Multi-epoch LO observations have the potential to detect a departure of brightness profile from spherical symmetry. Each LO event provides a uniform disk (UD) angular diameter along the position angle of the occultation. Any significant difference in the UD angular diameter values of multi-epoch LO observations signifies a brightness asymmetry. In this paper, we report for the first time three epoch UD angular diameter values of a SRV UZ Arietis using the LO technique at 2.2 $μm$. Optical linear polarization of the source observed by us recently is also reported. The asymmetric brightness distribution of UZ Ari suggested by a small difference in the fitted UD values for the three epochs, is discussed in the context of optical polarization exhibited by the source and the direction of polarization axis in the plane of the sky.

description: Gate-layouts of spin qubit devices are commonly adapted from previous successful devices. As qubit numbers and the device complexity increase, modelling new device layouts and optimizing for yield and performance becomes necessary. Simulation tools from advanced semiconductor industry need to be adapted for smaller structure sizes and electron numbers. Here, we present a general approach for electrostatically modelling new spin qubit device layouts, considering gate voltages, heterostructures, reservoirs and an applied source-drain bias. Exemplified by a specific potential, we study the influence of each parameter. We verify our model by indirectly probing the potential landscape of two design implementations through transport measurements. We use the simulations to identify critical design areas and optimize for robustness with regard to influence and resolution limits of the fabrication process.

description: This paper reports on a co-laborative laboratory ethnography in a molecular biology laboratory conducting research on environmental epigenetics. It focuses on a single study concerned with the material implications of social differentiation. The analysis briefly raises biopolitical concerns. Its main concern lies with an understanding of the human body as local in its working infrastructure or "inner laboratory", an understanding that emerges from the co-laborative inquiry between biologists and anthropologist. This co-laborative mode of inquiry raises productive tensions within biology as to the universal or local nature of human nature and within anthropology as to the status of human biology within social theory. The paper cannot resolve this tension. Rather it explores it as an epistemic object in the context of interdisciplinarity, ontography and co-laboration. In concluding, it specifies co-laboration as temporary, non-teleological joint epistemic work aimed at producing new kinds of reflexivity.

description: This study investigated mentoring practices of university-based tutors (UTs) and the impact these practices had on the development of pre-service teachers’ (PSTs’) professional knowledge for teaching physics in Chile. This study scrutinised how UTs supported PSTs’ articulation of their knowledge for teaching during a practicum. Data from interviews, reflective journals, and mentoring conversations (MCs) between a UT and a PST were collected from two cases. The mentoring roles UTs adopt can influences MCs and impact PSTs’ professional knowledge for teaching. Additionally, the methodology used can be of help in developing and evaluating mentoring programs in support of early career teachers.

description: Recent findings in neuroscience have shown differential patterns in brain activity in response to similar stimuli and activities across cultural and social differences. This calls for a framework to understand how such differences may come to be implemented in brains and neurons. Based on strands of research in social anthropology, we argue that human practices are characterized by particular patterns, and that participating in these patterns orders how people perceive and act in particular group- and context-specific ways. This then leads to a particular patterning of neuronal processes that may be detected using e.g. brain imaging methods. We illustrate this through (a) a classical example of phoneme perception (b) recent work on performance in experimental game play. We then discuss these findings in the light of predictive models of brain function. We argue that a 'culture as patterned practices' approach obviates a rigid nature-culture distinction, avoids the problems involved in conceptualizing 'culture' as a homogenous grouping variable, and suggests that participating as a competent participant in particular practices may affect both the subjective (first person) experience and (third person) objective measures of behavior and brain activity.

description: On June 27, 2006, the NIH conducted a workshop to review published data and current field practices supporting the use of self-obtained vaginal swabs (SOVs) as specimens for diagnosis of sexually transmitted infections (STIs). The workshop also explored the design of studies that could support FDA clearance of SOVs for STI testing, particularly for specimens collected in nonclinical settings including patients’ homes. This report summarizes the workshop findings and recommendations. Participants concluded that self-obtained vaginal swabs are well accepted by women of all ages and that SOVs perform as well as or better than other specimen types for Chlamydia trachomatis and Neisseria gonorrhoeae detection using transcription-mediated amplification. In addition, workshop participants recommended the validation of SOV testing by public health practitioners and manufacturers of STI diagnostic tests to expedite incorporation of SOVs as a diagnostic option in clinical and nonclinical settings for Chlamydia trachomatis and Neisseria gonorrhoeae testing. Similarly, SOVs should be explored for use in the diagnosis of other sexually transmitted pathogens.

description: BACKGROUND: Male circumcision (MC) decreases the risk of human immunodeficiency virus (HIV) acquisition in men. We explored associations between MC of the primary sex partner and women's risk of acquisition of chlamydial (Ct), gonococcal (GC), or trichomonal (Tv) infections.

METHODS: We analyzed data from a prospective study on hormonal contraception and incident human immunodeficiency virus/sexually transmitted infection (STI) among women from Uganda, Zimbabwe, and Thailand. At enrollment and each follow-up visit, we collected endocervical swabs for polymerase chain reaction identification of Ct and GC; Tv was diagnosed by wet mount. Using Cox proportional hazards models, we compared time to STI acquisition for women according to their partner's MC status.

RESULTS: Among 5925 women (2180 from Uganda, 2228 from Zimbabwe, and 1517 from Thailand), 18.6% reported a circumcised primary partner at baseline, 70.8% reported an uncircumcised partner, and 9.7% did not know their partner's circumcision status. During follow-up, 408, 305, and 362 participants had a first incident Ct, GC, or Tv infection, respectively. In multivariate analysis, after controlling for contraceptive method, age, age at coital debut, and country, the adjusted hazard ratio (HR) comparing women with circumcised partners with those with uncircumcised partners for Ct was 1.25 [95% confidence interval (CI) 0.96-1.63]; for GC, adjusted HR 0.99 (95% CI 0.74-1.31); for Tv, adjusted HR 1.05 (95% CI 0.80-1.36), and for the 3 STIs combined, adjusted HR 1.02 (95% CI 0.85-1.21).

CONCLUSIONS: MC was not associated with women's risk of acquisition of Ct, GC, or Tv infection in this cohort.

description: Optical waveguides, covered with thin films, which transmittance can be controlled by external action, are widely used in various applications from optical modulators to saturable absorbers. It is natural to suggest that the waveguide losses will be proportional to the covering material absorption. We demonstrate that under certain conditions this simple assumption fails. Instead, we observe the reduction of the film material absorption can lead to an increase in the waveguide propagation losses. For this, we use a side polished fiber covered with a single-walled carbon nanotube thin film whose absorption is attenuated either due to saturable absorption or electrochemical gating. For the films thicker than 50 nm, we observe saturable absorption to turn into light induced absorption with nonmonotonic dependence on the incident power. With a numerical simulation and analytical approach, we identify that this nontrivial behavior comes from mode reshaping and predict required parameters for its observation.

description: We offer a pedestrian level review of the wall-crossing invariants. The story begins from the scattering theory in quantum mechanics where the spectrum reshuffling can be related to permutations of S-matrices. In non-trivial situations, starting from spin chains and matrix models, the S-matrices are operator-valued and their algebra is described in terms of R- and mixing (Racah) U-matrices. Then, the Kontsevich-Soibelman invariants are nothing but the standard knot invariants made out of these data within the Reshetikhin-Turaev-Witten approach. The R- and Racah matrices acquire a relatively universal form in the quasiclassical limit, where the basic reshufflings with the change of moduli are those of the Stokes line. Natural from this point of view are matrices provided by the modular transformations of conformal blocks (with the usual identification R=T and U=S), and in the simplest case of the first degenerate field (2,1), when the conformal blocks satisfy a second order Shroedinger-like equation, the invariants coincide with the Jones (N=2) invariants of the associated knots. Another possibility to construct knot invariants is to realize the cluster coordinates associated with reshufflings of the Stokes lines immediately in terms of check-operators acting on the solutions to the Knizhnik-Zamolodchikov equations. Then, the R-matrices are realized as products of successive mutations in the cluster algebra and are manifestly described in terms of quantum dilogarithms ultimately leading to the Hikami construction of knot invariants.

description: It is proposed to exploit the decay of the meson ${B}^+ \rightarrow p π^+ π^+ \barΣ_c^{--}$ and of its charge conjugate $B^-$ copiously produced at LHC to obtain a sample of $Λ_c$ baryons through the strong decay $Σ_c \rightarrow Λ_c π$. The sample thus obtained is not affected by biases typically introduced by selections that depend on specific decay modes. Therefore it allows a measurement of the absolute branching fraction for the decay of the $Λ_c$ baryon into $ p K π$ or into other observable final states to be performed in a model independent manner. The accuracy that can be achieved with this method is discussed and it is shown that it would be either competitive with or an improvement over current measurements.

description: In space applications, hardware (HW) implementation is made more expensive not only by the levels of performance required, but also by complex and rigorous HW qualification tests. Reducing qualification cost and time is thus a key design requirement. In this paper, a new versatile transmitter is proposed for space telemetry, capable of soft-switching across different linear and continuous phase modulation schemes while maintaining the same hardware structure. This permits a single HW qualification to ``cover'' diverse uses of the same hardware, and thus avoid re-qualification in case of configuration changes. The envisaged solution foresees the use of a single filter, suitable not only for linear modulations such as M-QAM, but also for continuous phase modulation methods. At this stage, we focus on pulse code modulation/frequency modulation (PCM/FM), for which we propose a minimum mean square error (MMSE) algorithm. The proposed algorithm, which adds to the system flexibility and effectiveness, may use a single first filter based on Laurent decomposition for initialization, if needed. Performances are assessed using the mean square error (MSE) measure between the proposed MMSE-modulated signal and the completely modulated signal. Simulation results confirm that the proposed algorithm leads to MSE values that are lower than the case of Laurent decomposition using the first component only.

description: In recent years, advanced research has focused on the direct learning and analysis of remote sensing images using natural language processing (NLP) techniques. The ability to accurately describe changes occurring in multi-temporal remote sensing images is becoming increasingly important for geospatial understanding and land planning. Unlike natural image change captioning tasks, remote sensing change captioning aims to capture the most significant changes, irrespective of various influential factors such as illumination, seasonal effects, and complex land covers. In this study, we highlight the significance of accurately describing changes in remote sensing images and present a comparison of the change captioning task for natural and synthetic images and remote sensing images. To address the challenge of generating accurate captions, we propose an attentive changes-to-captions network, called Chg2Cap for short, for bi-temporal remote sensing images. The network comprises three main components: 1) a Siamese CNN-based feature extractor to collect high-level representations for each image pair; 2) an attentive decoder that includes a hierarchical self-attention block to locate change-related features and a residual block to generate the image embedding; and 3) a transformer-based caption generator to decode the relationship between the image embedding and the word embedding into a description. The proposed Chg2Cap network is evaluated on two representative remote sensing datasets, and a comprehensive experimental analysis is provided. The code and pre-trained models will be available online at https://github.com/ShizhenChang/Chg2Cap.

description: Motivated by the experimental synthesis of two-dimensional (2D) perovskite materials, we study the stability of 2D SrTiO$_3$ from first principles. We find that the TiO$_6$ octahedral rotations emerge in 2D SrTiO$_3$ with a rotation angle twice that in the 3D bulk. The rotation angle decreases significantly with the film thickness, reflecting the strong interlayer coupling that is absent in the conventional 2D materials. Using the molecular dynamics simulations, the cubic-like phase is found to appear above 1000 K that is much higher than the transition temperature of 3D SrTiO$_3$.

description: Recent progress in optomechanical systems may soon allow the realization of optomechanical arrays, i.e. periodic arrangements of interacting optical and vibrational modes. We show that photons and phonons on a honeycomb lattice will produce an optically tunable Dirac-type band structure. Transport in such a system can exhibit transmission through an optically created barrier, similar to Klein tunneling, but with interconversion between light and sound. In addition, edge states at the sample boundaries are dispersive and enable controlled propagation of photon-phonon polaritons.

description: Observations of redshift-space distortions in spectroscopic galaxy surveys offer an attractive method for observing the build-up of cosmological structure, which depends both on the expansion rate of the Universe and our theory of gravity. In preparation for analysis of redshift-space distortions from the Baryon Oscillation Spectroscopic Survey (BOSS) final data release we compare a number of analytic and phenomenological `streaming' models, specified in configuration space, to mock catalogs derived in different ways from several N-body simulations. The galaxies in each mock catalog have properties similar to those of the higher redshift galaxies measured by BOSS but differ in the details of how small-scale velocities and halo occupancy are determined. We find that all of the analytic models fit the simulations over a limited range of scales while failing at small scales. We discuss which models are most robust and on which scales they return reliable estimates of the rate of growth of structure: we find that models based on some form of resummation can fit our N-body data for BOSS-like galaxies above $30\,h^{-1}$Mpc well enough to return unbiased parameter estimates.

description: For decades, the Astrophysics Data System (ADS) has been a critical tool for astrophysics research, enabling scientists to discover and access vast bodies of literature and data. Now, with the launch of the Science Explorer (SciX), the platform is evolving to meet the interdisciplinary demands of NASA’s Science Mission Directorate. SciX, built on ADS’s robust foundation, has rapidly expanded its scope to integrate resources from Astrophysics, Heliophysics, Planetary Science, Earth Science, and Biological & Physical Sciences, creating a unified hub for literature, data, and software discovery.

This presentation will highlight the remarkable growth of SciX since its beta launch at AGU 2023. Leveraging cutting-edge technologies such as AI, machine learning, and large language models, SciX is enhancing the platform’s ability to support the diverse needs of researchers across multiple scientific disciplines. Attendees will learn how the platform’s advanced bibliometric visualizations, semantic search capabilities, and personalized discovery tools are transforming the way scientists interact with data and research outputs.

In addition, we will share insights from the ADS/SciX team’s engagement with the astrophysics community and how this feedback has guided ongoing platform enhancements. These efforts ensure that ADS remains a cutting-edge resource for future generations of researchers while adapting to the changing landscape of interdisciplinary research.

SciX is fully aligned with the principles of FAIR (Findable, Accessible, Interoperable, Reusable) and Open Science, empowering researchers to manage and share their publications, data, and software within an open, user-centric platform. The session will also spotlight the SciX Ambassador Program, which is fostering a global network of advocates committed to promoting open science and cross-disciplinary collaboration. Together, ADS and SciX are not only expanding the boundaries of research discovery but also driving NASA’s mission to enhance our understanding of the universe and our planet.

description: Dengue is a vector-borne disease transmitted from an infected human to an Aedes mosquito, during a blood-meal. Dengue is still a major public health problem. A model for the disease transmission is presented, composed by human and mosquitoes compartments. The aim is to simulate the effects of seasonality, on the vectorial capacity and, consequently, on the disease development. Using entomological information about the mosquito behavior under different temperatures and rainfall, simulations are carried out and the repercussions analyzed. The basic reproduction number of the model is given, as well as a sensitivity analysis of model's parameters. Finally, an optimal control problem is proposed and solved, illustrating the difficulty of making a trade-off between reduction of infected individuals and costs with insecticide.

description: Narrow band images covering strong emission lines are efficient to survey supernova remnants (SNRs) in nearby galaxies. Using the narrow band images provided by the Local Group Galaxy Survey we searched for SNRs in M33. Culling the objects with enhanced [SII]/Ha and round morphology in the continuum-subtracted Ha and [SII] images, we produce a list of 199 sources. Among them 79 are previously unknown. Their progenitor and morphology types were classified. A majority of the sample (170 objects) are likely remnants of core-collapse SNe, and 29 are remnants of Type Ia SNe. The cumulative size distribution of these objects is found to be similar to that of the M31 remnants derived in the similar way. We obtain a power law slope, a = 2.38 + 0:05. Thus a majority of the sources are considered to be in the Sedov-Taylor phase, consistent with previous findings. The histogram of the emission line ratio ([SII]/Ha) of the remnants has two concentrations at [SII]/Ha ~0.55 and ~0.8, as in M31. Interestingly Lx (and L20cm) of the compact center-bright objects are correlated with their optical luminosity. The remnants with X-ray emission have brighter optical surface brightness and smaller diameters than those without X-ray emission.

Wake Effects on Drift in Two-Dimensional Inviscid Incompressible Flows

description: This investigation analyzes the effect of vortex wakes on the Lagrangian displacement of particles induced by the passage of an obstacle in a two-dimensional incompressible and inviscid fluid. In addition to the trajectories of individual particles, we also study their drift and the corresponding total drift areas in the Föppl and Kirchhoff potential flow models. Our findings, which are obtained numerically and in some regimes are also supported by asymptotic analysis, are compared to the wakeless potential flow which serves as a reference. We show that in the presence of the Föppl vortex wake some of the particles follow more complicated trajectories featuring a second loop. The appearance of an additional stagnation point in the Föppl flow is identified as a source of this effect. It is also demonstrated that, while the total drift area increases with the size of the wake for large vortex strengths, it is actually decreased for small circulation values. On the other hand, the Kirchhoff flow model is shown to have an unbounded total drift area. By providing a systematic account of the wake effects on the drift, the results of this study will allow for more accurate modeling of hydrodynamic stirring.

description: Technical files are a very important part of the Argo dataset. They allow us to diagnose systematic faults and track array performance. In the past it was assumed that all DACs knew how these should be filled and we only needed to provide details as to the names and formats. With the development of Argo format version 3.1 and the more detailed format checker, it would be useful to describe more fully how the technical files are generated and how their contents are determined. We therefore provide this user's guide to the technical files.

AI reasoning

description: Recent research underscores a critical shift in understanding AI reasoning by moving beyond mere input-output behaviors to analyzing the internal states of models. This paper explores the transformative potential of hidden states as an intrinsic medium for reasoning, questioning whether cognitive processes in AI can be enhanced independently of natural language representations. We propose a novel framework, PathThinker, that explicitly treats hidden states as a fundamental reasoning substrate, potentially unlocking greater interpretability, reliability, and adaptability. While this concept is yet to be fully implemented, we discuss its feasibility, potential advantages, and challenges.
