description: Hydrogen sulphide (H2S), a newly identified gasotransmitter, can be endogenously produced by cystathionine gamma-lyase (CSE) in the cardiovascular system. This study investigated the role of the CSE/H2S system on lipid overload-induced lipotoxicity and cardiac senescence. Lipid overload in rat cardiomyocyte cells (H9C2) promoted intracellular accumulation of lipid, oxidative stress, mitochondrial dysfunctions, lipid peroxidation and inhibited cell viability, all of which could be reversed by exogenously applied H2S. Further data revealed that H2S protected H9C2 cells from lipid overload-induced senescence by altering the expressions of lipid metabolism-related genes and inhibiting cellular acetyl-CoA and global protein acetylation. Enhancement of protein acetylation abolished the protective role of H2S on cardiac senescence. In vivo, knockout of the CSE gene strengthened cardiac lipid accumulation, protein acetylation, and cellular ageing in high fat diet-fed mice. Taken together, the CSE/H2S system is capable of maintaining lipid homeostasis and cellular senescence in heart cells under lipid overload.
Hybrid stars may have an inverted structure

description: We propose a new stellar structure of compact stars, the ``cross stars" that consist of a hadronic matter core and a quark matter crust, with an inverted structure compared to the conventional hybrid stars. This distinct stellar structure naturally arises from the quark matter to hadronic matter transition associated with the chemical potential crossing, in the context of the quark matter hypothesis that either strange or up-down quark matter is the ground state of baryonic matter at low pressure. We find that the interplay between the hadronic matter and quark matter compositions of cross stars can help to reconcile the small radii constraints indicated by the LIGO/Virgo GW170817 event, the large radii constraints set for massive compact stars by recent NICER X-ray observations, and the recent observation of the most-massive pulsar PSR J0952-0607. This leaves more space open for the equation of states of both hadronic matter and quark matter.

Hosking integral in nonhelical Hall cascade

description: The Hosking integral, which characterizes magnetic helicity fluctuations in subvolumes, is known to govern the decay of magnetically dominated turbulence. Here we show that, when the evolution of the magnetic field is controlled by the motion of electrons only, as in neutron star crusts, the decay of the magnetic field is still controlled by the Hosking integral, but now it has effectively different dimensions than in ordinary magnetohydrodynamic (MHD) turbulence. This causes the correlation length to increase with time $t$ like $t^{4/13}$ instead of $t^{4/9}$ in MHD. The magnetic energy density decreases like $t^{-10/13}$, which is slower than in MHD, where it decays like $t^{-10/9}$. These new analytic results agree with earlier numerical simulations for the nonhelical Hall cascade.

description: This study aimed to evaluate the therapeutic role of erythropoietin (EPO) or myoinositol versus metformin (MET) in improving the reproductive functions and glucose tolerance in a rat model of polycystic ovary (PCOS). Oral letrozole (LTZ) was used for induction of PCOS in wester rats for 21 days, after that, MET, EPO and myoinositol were administered for the following 21 days. The LTZ-induced PCOS rats have lost their oestrous cyclicity and become fixed at the diestrus phase, developed insulin resistance, abnormal sex and gonadotrophin hormone serum levels, increased cystic follicles, decreased number of the growing follicles and very little or no corpora lutea on microscopic examination, which were reversed by the three drugs, MET, EPO and myoinositol. MET and myoinositol were mostly equally effective in improving the reproductive manifestations of the disease. However, EPO was most effective in decreasing the insulin level observed in this LTZ-induced model of PCOS.
NOPE-SAC: Neural One-Plane RANSAC for Sparse-View Planar 3D Reconstruction

description: This paper studies the challenging two-view 3D reconstruction in a rigorous sparse-view configuration, which is suffering from insufficient correspondences in the input image pairs for camera pose estimation. We present a novel Neural One-PlanE RANSAC framework (termed NOPE-SAC in short) that exerts excellent capability to learn one-plane pose hypotheses from 3D plane correspondences. Building on the top of a siamese plane detection network, our NOPE-SAC first generates putative plane correspondences with a coarse initial pose. It then feeds the learned 3D plane parameters of correspondences into shared MLPs to estimate the one-plane camera pose hypotheses, which are subsequently reweighed in a RANSAC manner to obtain the final camera pose. Because the neural one-plane pose minimizes the number of plane correspondences for adaptive pose hypotheses generation, it enables stable pose voting and reliable pose refinement in a few plane correspondences for the sparse-view inputs. In the experiments, we demonstrate that our NOPE-SAC significantly improves the camera pose estimation for the two-view inputs with severe viewpoint changes, setting several new state-of-the-art performances on two challenging benchmarks, i.e., MatterPort3D and ScanNet, for sparse-view 3D reconstruction.

Challenges in inferring spectroscopic fundamental stellar parameters

Stars: Fundamental parameters

description: Fundamental stellar parameters are key for the understanding of many different fields in Astrophysics. There are several techniques available that can be used to characterize fundamental stellar parameters. Spectroscopy is one of the best keys to unlock the fundamental properties of the stars, mostly inferred based on the study of their atmosphere layers. Here we start by a brief description of the procedure of a well established spectroscopic analysis method based on line by line analysis. This method has been used for several years to derive homogeneous spectroscopic stellar parameters, mostly focused in the study of planet-host
 stars but not only. We present how these parameters compare with others derived with different spectroscopic analysis methodologies and show where these methods are more and less reliable. One of the problems is to accurately constrain the stellar surface gravity and we show how we can use asteroseismology and astrometry to constrain and improve its determination and access its dependence with other spectroscopic parameters.

description: We propose that the $X(3915)$ observed in the $J/ψ\,ω$ channel is the same state as the $χ_{c2}(3930)$, and the $X(3960)$, observed in the $D_s^+D_s^-$ channel, is an $S$-wave $D_s^+ D_s^-$ hadronic molecule. In addition, the $J^{PC}=0^{++}$ {component in the $B^+\to D^+D^-K^+$} assigned to the $X(3915)$ in the current {\it Review of Particle Physics} has the same origin as the $X(3960)$, which has a mass around 3.94~GeV. To check the proposal, the available data in the $D\bar D$ and $D_s^+ D_s^-$ channels from both $ B$ decays and $γγ$ fusion reaction are analyzed considering both the $D\bar D$-$D_s\bar D_s$-$D^*\bar D^*$-$D_s^*\bar D_s^*$ coupled channels with $0^{++}$ and a $2^{++}$ state introduced additionally. It is found that all the data in different processes can be simultaneously well reproduced, and the coupled-channel dynamics produce four hidden-charm scalar molecular states with masses around 3.73, 3.94, 3.99 and 4.23~GeV, respectively. The results may deepen our understanding of the spectrum of charmonia as well as of the interactions between charmed hadrons.

description: A novel version of the electric Aharonov-Bohm effect is proposed where the quantum system which picks up the Aharonov-Bohm phase is confined to a Faraday cage with a time varying, spatially uniform scalar potential. The electric and magnetic fields in this region are effectively zero for the entire period of the experiment. The observable consequence of this version of the electric Aharonov-Bohmn effect is to shift the energy levels of the quantum system rather than shift the fringes of the 2-slit interference pattern. We show a strong mathematical connection between this version of the scalar electric AB effect and the AC Stark effect.

Spin-orbit amplitudes for decays with arbitrary spin

description: In this paper, we propose a method to construct the decay amplitudes in the orbital ($L$) and spin ($S$) coupling scheme for particles with arbitrary spins. For the $1\to 2$ decay with only massive particles involved, the angular dependence is completely encoded in the angular momentum part, and the spins of daughter particles are coupled in the rest frame of the mother particle, which contributes only a constant factor. For the sequential decay, the total amplitude is constructed by the two $1\to2$ amplitudes evaluated in the rest frame of their own mother particles, and then they are transformed to the common frame, usually chosen as the laboratory frame, by certain Lorentz transformations. In this way, it is easy to add the amplitudes of possible different decay chains coherently. If massless particles show up in the final states, the polarizations are expressed in helicity basis and the amplitudes are modified correspondingly.

description: A search for the rare decays $W^{+}\rightarrow{D^{+}_{s}γ}$ and $Z\rightarrow{D^{0}γ}$ is performed using proton-proton collision data collected by the LHCb experiment at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 2.0 fb$^{-1}$. No significant signal is observed for either decay mode and upper limits on their branching fractions are set using $W^{+}\rightarrow{μ^{+}ν}$ and $Z\rightarrow{μ^{+}μ^{-}}$ decays as normalization channels. The upper limits are $6.5\times10^{-4}$ and $2.1\times10^{-3}$ at 95% confidence level for the $W^{+}\rightarrow{D^{+}_{s}γ}$ and $Z\rightarrow{D^{0}γ}$ decay modes, respectively. This is the first reported search for the $Z\rightarrow{D^{0}γ}$ decay, while the upper limit on the $W^{+}\rightarrow{D^{+}_{s}γ}$ branching fraction improves upon the previous best limit.

description: The long-lived and optically addressable spin states of silicon vacancies ($\mathrm{V}_\mathrm{Si}$) in 4H-SiC make them promising qubits for quantum communication and sensing. These color centers can be created in both the hexagonal (V1) and in the cubic (V2) local crystallographic environments of the 4H-SiC host. While the spin of the V2 center can be efficiently manipulated by optically detected magnetic resonance at room temperature, spin control of the V1 centers above cryogenic temperatures has so far remained elusive. Here, we show that the dynamic strain of surface acoustic waves can overcome this limitation and efficiently excite magnetic resonances of V1 centers up to room temperature. Based on the width and temperature dependence of the acoustically induced spin resonances of the V1 centers, we attribute them to transitions between spin sublevels in the excited state. The acoustic spin control of both kinds of $\mathrm{V}_\mathrm{Si}$ centers in their excited states opens new ways for applications in quantum technologies based on spin-optomechanics.

Publisher: name: Zenodo

description: The so-called Tayler-Spruit dynamo has been proposed to provide an effective angular momentum transport in stellar radiative zones. This dynamo process could also play an important role to explain the formation of highly magnetized neutron stars called magnetars (Barrère et al. 2022, arXiv:2206.01269). For many years however, our understanding of it relied on simplified analytical prescriptions. Recent numerical advances start to provide us with a 3D picture of this dynamo. In this context, I will present new results from 3D MHD numerical simulations in which a Tayler instability-driven dynamo is acting in a stably stratified region (arXiv:2306.12296).

description: Non-equilibrium dynamics of many-body quantum systems under the effect of measurement protocols is attracting an increasing amount of attention. It has been recently revealed that measurements may induce different non-equilibrium regimes and an abrupt change in the scaling-law of the bipartite entanglement entropy. However, our understanding of how these regimes appear, how they affect the statistics of local quantities and, finally whether they survive in the thermodynamic limit, is much less established. Here we investigate measurement-induced phase transitions in the Quantum Ising chain coupled to a monitoring environment. In particular we show that local projective measurements induce a quantitative modification of the out-of-equilibrium probability distribution function of the local magnetization. Starting from a GHZ state, the relaxation of the paramagnetic and the ferromagnetic order is analysed. In particular we describe how the probability distribution of the former shows different behaviour in the area-law and volume-law regimes.

description: The synthesis and application of a series of crosslinkable bis(diphenylamine)‐substituted mixed dihydroindeno[1,2‐b]fluorenes as model systems for the fabrication of solution‐processed, multilayer organic light‐emitting diodes (OLEDs) is described. Introducing a novel functionalization approach by C(sp³)−C(sp²) Suzuki‐Miyaura reactions, the synthesis is based on a modular strategy, leading to eight nearly isoelectronic derivatives that allow for the observation of structure‐property relationships in the context of crosslinkable hole‐transport materials, e. g., for use in OLEDs. By systematically altering structural parameters, such as the number of crosslinkable oxetane moieties per molecule (2–6 moieties) and their position of attachment (geminal and/or lateral), process‐relevant thermal properties such as thermal stability (Td95, 170‐350°C) and glass‐transition temperature (15‐100°C) can be influenced and allow for the investigation of their impact on the crosslinking behavior and the resulting device performance.

description: Accurate and robust extrinsic calibration is necessary for deploying autonomous systems which need multiple sensors for perception. In this paper, we present a robust system for real-time extrinsic calibration of multiple lidars in vehicle base frame without the need for any fiducial markers or features. We base our approach on matching absolute GNSS and estimated lidar poses in real-time. Comparing rotation components allows us to improve the robustness of the solution than traditional least-square approach comparing translation components only. Additionally, instead of comparing all corresponding poses, we select poses comprising maximum mutual information based on our novel observability criteria. This allows us to identify a subset of the poses helpful for real-time calibration. We also provide stopping criteria for ensuring calibration completion. To validate our approach extensive tests were carried out on data collected using Scania test vehicles (7 sequences for a total of ~ 6.5 Km). The results presented in this paper show that our approach is able to accurately determine the extrinsic calibration for various combinations of sensor setups.

Impacts of central mixing and nuclear reactions network on the size of convective cores

description: Convective cores are the hydrogen reservoirs of main-sequence stars that are more massive than around 1.2 solar masses. The characteristics of the cores consequently have a strong impact on the structure and evolution of the star. The high quality of the Kepler mission dataset allowed to better constrain the core extension and therefore to obtain more accurate ages. However, such results rely on stellar evolution codes, in which simple assumptions are often made on the physics in the core. Indeed, the convective mixing is commonly considered to be instantaneous and the most basic nuclear networks assume that both Lithium and Beryllium are at their equilibrium abundance. In this talk, we show how those two hypotheses lead to significant differences in the central composition of the elements for which the timescale to reach nuclear equilibrium is lower than the convective timescale. We present how this impacts the nuclear energy production and therefore the size of convective cores in low-mass stars. As those stars exhibit solar-like oscillations, we use data from the Kepler mission to study the impact of this effect on the seismic modelling. We find that the overshoot parameter of the best-fit model is significantly higher when using basic nuclear reaction networks. Thus, it is necessary to have consistent nuclear reactions and central mixing prescriptions when using observationally-calibrated overshoot parameters. This is key in the framework of the Plato mission, especially to ensure accurate age determinations within the main-sequence grid modeling pipeline.

description: Dark photon dark matter that has a kinetic mixing with the Standard Model photon can resonantly convert in environments where its mass $m_{A'}$ coincides with the plasma frequency. We show that such conversion in neutron stars or accreting white dwarfs in the galactic centre can lead to detectable radio signals. Depending on the dark matter spatial distribution, future radio telescopes could be sensitive to values of the kinetic mixing parameter that exceed current constraints by orders of magnitude for $m_{A'} \in \left(6\times 10^{-6},7\times 10^{-4}\right)$ eV.

Interaction-Aware Motion Planning for Autonomous Vehicles with Multi-Modal Obstacle Uncertainty Predictions

description: This paper proposes an interaction and safety-aware motion-planning method for an autonomous vehicle in uncertain multi-vehicle traffic environments. The method integrates the ability of the interaction-aware interacting multiple model Kalman filter (IAIMM-KF) to predict interactive multi-modal maneuvers of surrounding vehicles, and the advantage of model predictive control (MPC) in planning an optimal trajectory in uncertain dynamic environments. The multi-modal prediction uncertainties, containing both the maneuver and trajectory uncertainties of surrounding vehicles, are considered in computing the reference targets and designing the collision-avoidance constraints of MPC for resilient motion planning of the ego vehicle. The MPC achieves safety awareness by incorporating a tunable parameter to adjust the predicted obstacle occupancy in the design of the safety constraints, allowing the approach to achieve a trade-off between performance and robustness. Based on the prediction of the surrounding vehicles, an optimal reference trajectory of the ego vehicle is computed by MPC to follow the time-varying reference targets and avoid collisions with obstacles. The efficiency of the method is illustrated in challenging highway-driving simulation scenarios and a driving scenario from a recorded traffic dataset.

Star Formation and Chemical Enrichment in Protoclusters

description: We examine star formation and chemical enrichment in protoclusters (PCs) using cosmological zoom-in hydrodynamic simulations. We find that the total star formation rate (SFR) in all PC ($>10^{14.4}\,h^{-1}$M$_\odot$) reaches $>10^4\,\mathrm{M}_\odot \mathrm{yr}^{-1}$ at $z=3$, equivalent to the observed PCs. The SFR in the Core region accounts for about $30\%$ of the total star formation in the PC at $z\gtrsim1$, suggesting the importance of the outer regions to reveal the evolution of galaxy clusters. We find that the total SFR of PC is dominated by galaxies with $10^{10}\,\le\,(\mathrm{M}_\star/M_\odot)\,\le\,10^{11}$, while more massive galaxies dominate the SFR in the Core. For the chemical abundance evolution, we find that the higher-density region has a higher metallicity and faster evolution. We show that the [O/Fe] vs. [Fe/H] relation turns down in the Core at $z=3.4$ due to the enrichment of Fe by Type Ia supernovae. We find no environmental effects for the mass--metallicity relations (MZR) or $\log$(N/O) vs. $12+\log$(O/H) for galaxies. We find that the chemical enrichment in galaxy clusters proceeds faster in the high redshift Universe ($z>1$). Our work will benefit future tomographic observations, particularly using PCs as unique probes of accelerated structure formation and evolution in high-density regions of the universe.

description: We investigate the implications of one vanishing minor in neutrino mass matrix using trimaximal mixing matrix. In this context, we analyse all six patterns of one vanishing minor zero in neutrino mass matrix and present correlations of the neutrino oscillation parameters. All the six patterns are found to be phenomenologically viable with the present neutrino oscillation data. We also predict the values of effective Majorana mass, the effective electron anti-neutrino mass and the total neutrino mass for all the patterns. The value obtained for the effective neutrino mass is within the reach future neutrinoless double $β$ decay experiments. We also propose a flavor model where such patterns can be generated within the seesaw model.

description: The aim of the present investigation was to elucidate the phytochemical characterisation, antimicrobial and antioxidant efficacies of methanol extracts of leaf, stem, and root parts of S. wightianus. The phytochemical characterisation by GC-MS analysis revealed the presence of different phytocompounds such as Lupenone (38.02% in leave extract), Leupeyl acetate (33.43% in root extract), 24- Noursa −3, 12- diene (27.16% stem extract). S. wightianus methanol extracts demonstrate IC50, 8.52 µg/ml, 7.72 µg/ml and 9.08 µg/ml using DPPH, FRAP and MCA scavenging assay, respectively. The antibacterial activity of different methanol extracts was evaluated against four microorganisms with a mean zone diameter of inhibition ranging from 13 to 19 mm. For quantitative phytochemical analysis, the highest Total Phenolic Content (TPC) and Total Flavonol Content (TFC-2) were found for steam methanol extract (321.7 mg GAE/g of dry extract, 162.4 mg QE/g of dry extract respectively).

description: Poly(3‐hexyl‐thiophene‐2,5‐diyl) (P3HT) is one of the most commonly used materials in organic electronics, yet it is considered to be rather unattractive for organic field‐effect transistors (OFETs) due to its tendency to oxidize under aerobic conditions. Strong p‐doping of P3HT by oxygen causes high off‐currents in such devices opposing the desired high on/off‐ratios. Herein, a new application‐oriented method involving the recently developed immobilizable organic n‐dopant 2‐(2‐((4‐azidobenzyl)oxy)phenyl)‐1,3‐dimethyl‐2,3‐dihydro‐1H‐benzoimidazol (o‐AzBnO‐DMBI) is presented allowing to process and operate P3HT OFETs in air. The n‐dopants compensate oxygen doping by trapping generated free holes, thereby rediminishing OFET off‐currents by approximately two orders of magnitude. At the same time, field‐effect mobilities remain high in the order of up to 0.19 cm² V⁻¹ s⁻¹. Due to the covalent attachment of the dopants to the host matrix after photochemical activation, a drift of the otherwise mobile ions within the device is prevented even at high operating voltages and, thus, hysteresis in the corresponding transfer characteristics is kept low. In this manner, the air instability of P3HT OFETs is successfully resolved paving an auspicious way toward OFET mass production. As the immobilization process employed here is nonspecific with respect to the host material, this strategy is transferable to other p‐type semiconductors.

autonomia
paradoja de la autonomia
intensificación del trabajo

description: La discusión pública sobre el teletrabajo refleja la percepción de que la movilidad combinada con la flexibilidad de la jornada laboral podría aportar beneficios tanto para la empresa como para los empleados y, en última instancia, también para la sociedad. En este documento de trabajo, se presentan casos apuntando a ventajas y desventajas. Hacia que lado se inclina la balanza depende del diseño concreto del modelo del trabajo móvil interconectado. El teletrabajo implica una mayor autonomía formal y responsabilidad de los trabajadores respecto a la gestión de su jornada laboral y en el lugar en que va a trabajar interconectado, pero también del cumplimiento de las normas legales que afectan al trabajo digital, especialmente las de seguridad y salud laboral. Se apela a la responsabilidad de los propios teletrabajadores cuando se trata de limitar la disponibilidad ampliada, regular el trabajo fuera de la jornada laboral y las horas extras registradas y no registradas para evitar las sobrecargas de trabajo. Estas tendencias, junto a su riesgo para la salud/bienestar de los trabajadores, son reconocidas y se discuten cada vez más como un problema social. Sin embargo, una mayor autonomía formal no significa (necesariamente) una mayor capacidad para hacer frente a las tareas laborales en los plazos fijados o mejores condiciones de trabajo sino que conducen muchas veces a la “paradoja de la autonomía”. En este contexto, el término de la “gestión de las demarcaciones sociales” cobra mayor relevancia. Hay un consenso de que este cambio del mundo laboral se produce de forma desigual. En algunos ámbitos aumenta la autonomía formal, mientras que en otras áreas el taylorismo continúa aplicándose y su uso se expande en algunos sectores de servicios. Cuando el teletrabajo móvil se implementa solo en base a las estrategias empresariales y los acuerdos individuales, sin que esté enmarcado en acuerdos colectivos, existe un mayor riesgo de que la balanza se incline en favor de la productividad y en detrimento de las condiciones de trabajo (p.ej. intensificación y densificación de trabajo) y la conciliación entre el trabajo y la vida privada

description: In this work, the preparation and fabrication of elastomeric opal films revealing reversible mechanochromic and pH‐responsive features are reported. The core–interlayer–shell (CIS) particles are synthesized via stepwise emulsion polymerization leading to hard core (polystyrene), crosslinked interlayer (poly(methyl methacrylate‐co‐allyl methacrylate), and soft poly(ethyl acrylate‐co‐butyl acrylate‐co‐(2‐hydroxyethyl) methacrylate) shell particles featuring a size of 294.9 ± 14.8 nm. This particle architecture enables the application of the melt‐shear organization technique leading to elastomeric opal films with orange, respectively, green brilliant reflection colors dependent on the angle of view. Moreover, the hydroxyl moieties as part of the particle shell are advantageously used for subsequent thermally induced crosslinking reactions enabling the preparation of reversibly tunable mechanochromic structural colors based on Bragg's law of diffraction. Additionally, the CIS particles can be loaded upon extrusion or chemically by a postfunctionalization strategy with organic dyes implying pH‐responsive features. This convenient protocol for preparing multi‐responsive, reversibly stretch‐tunable opal films is expected to enable a new material family for anti‐counterfeiting applications based on external triggers.
