The NC effects are modeled through a semiclassical approach equivalent to an NC gauge theory, resulting in an effective metric featuring an additional off-diagonal ((r - \phi)) component. Focusing on massless Dirac fields, we compute the QNM frequencies using the continued fraction method, refined via Gaussian elimination to handle the resulting six-term recurrence relations. The analysis reveals significant modifications in both oscillation frequencies and damping rates compared to the commutative Reissner-Nordström case. Notably, the QNM spectrum exhibits a Zeeman-like splitting behavior induced by the NC parameter, highlighting the potential of NC geometry to probe quantum gravity effects in black hole physics.

However, the model fails to clearly demonstrate the connections among these particles, raising doubts about whether they are truly the basic building blocks of the universe. This article introduces a new theoretical framework: Yin–Yang particles, which are proposed to be more fundamental than those in the Standard Model and capable of explaining gravity and electromagnetic transduction. Inspired by Taoist philosophy, which emphasizes the duality of Yin (darkness) and Yang (brightness), this theory presents these particles with distinct interpretations. The proposed framework aims to clarify various physical phenomena, including light, electrons, quarks, black holes, and electromagnetic waves. While purely hypothetical, it offers a compelling perspective on the nature of the universe.

The recalculation indicates that the pressure of internal ‚naked’ photons on the bag’s surface of radius ai = 0.59, which explains the nucleon's quarks deconfining temperature (2x1012 K), for a current quark's radius of ordinary nuclear temperature: rq = 0.2 fm, is: Psi0(ai) = 6.688x1033 N/m2, corresponding to a ,bag' constant: Bi l= 41.8 MeV/fm3, value which verify the CGT's model of strong ' interaction between quarks and that between nucleons considered in a vertical model, by a constant of the bag's field variation of value: = 0.34 fm. The total potential of interaction between two nucleons results in the form of a modified Sombrero-type potential, with an attractive part= Va(r) = Va0e-r/* and a repulsive part: Vr(r) = Vr0e-7r/*, (* = 0.8 fm). The explanatory model indicates the existence of a bag pressure for each composite particle but also for quarks and the bag’s constant variation with the mass and the intrinsic temperature of the particle’s kernel.

Using data from the Dark Energy Spectroscopic Instrument (DESI) Y1 survey, we detect the intrinsic alignment (IA) of multiplets to the galaxy-traced matter field out to separations of 100ℎ −1Mpc. Unlike traditional IA measurements of individual galaxies, this estimator is not limited by imaging of galaxy shapes and allows for direct IA detection beyond redshift 𝑧 = 1. Multiplet alignment is a form of higher-order clustering, for which the scale-dependence traces the underlying tidal field and amplitude is a result of small-scale (< 1ℎ −1Mpc) dynamics. Within samples of bright galaxies (BGS), luminous red galaxies (LRG) and emission-line galaxies (ELG), we find similar scale-dependence regardless of intrinsic luminosity or colour. This is promising for measuring tidal alignment in galaxy samples that typically display no intrinsic alignment. DESI’s LRG mock galaxy catalogues created from the AbacusSummit N-body simulations produce a similar alignment signal, though with a 33% lower amplitude at all scales. An analytic model using a non-linear power spectrum (NLA) only matches the signal down to 20ℎ −1Mpc. Our detection demonstrates that galaxy clustering in the non-linear regime of structure formation preserves an interpretable memory of the large-scale tidal field. Multiplet alignment complements traditional two-point measurements by retaining directional information imprinted by tidal forces, and contains additional line-of-sight information compared to weak lensing. This is a more effective estimator than the alignment of individual galaxies in dense, blue, or faint galaxy samples.

This solution characterizes the external vacuum of a spherical Brans-Dicke star and is distinguished by two adjustable parameters. Notably, a rigorous establishment of the relationship between these parameters and the star's properties is currently lacking. In this work, we endeavor to address this gap by deriving the comprehensive exterior solution of Brans Class I, articulated in relation to the total energy and total pressure of the spherically symmetric gravity source. This derived solution facilitates the precise computation of all post-Newtonian parameters in Brans-Dicke gravity for the distant field regions of a spherical source. Specifically, we obtain an alternative analytical expression for the γ parameter, denoted as γ exact = ω+1+(ω+2) Θ ω+2+(ω+1) Θ, where Θ represents the ratio of the total pressure P∗∥ + 2P∗⊥ to the total energy E∗ contained within the mass source. Our non-perturbative γ formula is universally applicable across varying field strengths and types of matter comprising the mass source. As a result, observational constraints on γ concurrently establish limits on ω and Θ. Significantly, the latter serves as a global characteristic of the mass source. On a broader scope, our formula underscores the significance of pressure (when Θ ̸= 0) in spherical Brans-Dicke stars and potentially in stars within other modified theories of gravitation.

Observationally constrained CME rates of young solar analogues are still lacking, as those require dedicated monitoring. We present medium resolution optical spectroscopic monitoring of a small sample of bright and prominent solar analogues over a period of three years using the 0.5m telescope at observatory Lustbühel Graz (OLG) of the University of Graz, Austria. The aim is the detection of flares and CMEs from those spectra. In more than 1700 hours of spectroscopic monitoring we found signatures of four flares and one filament eruption on EK Dra which has been reported in previous literature, but we complementarily extended the data to cover the latter phase. The other stars did not reveal detectable signatures of activity. For these non-detections we derive upper limits of occurrence rates of very massive CMEs, which are detectable with our observational setup, ranging from 0.1 to 2.2 day−1 , but these may be even smaller than the given rates considering observational biases. Furthermore, we investigate the detectability of flares/CMEs in OLG spectra by utilizing solar 2D Hα spectra from MEES solar observatory. We find that solar-sized events are not detectable within our observations. By scaling up the size of the solar event, we show that with a fractional active region area of 18% in residual spectra and 72% in equivalent width time series derived from the same residuals that solar events are detectable if they had hypothetically occurred on HN Peg.

Here, we reveal that multi-level neutral cold atoms can mediate both dissipative and coherent couplings. Interestingly, we investigate and practically implement this paradigm in experiments, successfully synthesizing a system with dual functionality as both a photonic qubit unidirectional router and a spin-wave diode. By manipulating the helicity of the field, we can effectively balance the coherence coupling and dissipative channel, thereby ensuring the unidirectional transfer of photonic qubits. The qubit fidelity exceeds 97.49 ± 0.39%, and the isolation ratio achieves 16.8 ± 0.11 dB while the insertion loss is lower than 0.36 dB. Furthermore, we show that the spin-wave diode can effectively achieve unidirectional information transfer by appropriately setting the coherent coupling parameters. Our work not only provides new ideas for the design of extensive components in quantum network, but also opens up new possibilities for non-Hermitian quantum physics, complex quantum networks, and unidirectional quantum information transfer.

The aim of this paper is to give a self-consistent review of sequential transport processes in such devices, based on the so-called ”orthodox” model. We calculate numerically the current-voltage (I–V ) curves, the conductance versus bias voltage (G–V ) curves, and the associated thermal transport in symmetric and asymmetric two-junction arrays such as Coulomb-blockade thermometers (CBTs), superconducting-insulator-normal-insulator-superconducting (SINIS) structures, and superconducting single-electron transistors (SETs). We investigate the behaviour of these systems at the singularity-matching bias points, the dependence of micro refrigeration effects on the charging energy of the island, and the effect of a finite superconducting gap on Coulomb-blockade thermometry.

However, besides greater HER activity, the maturity and diversity of modification strategies result in a more puzzling relationship between electrocatalytic mechanisms and the corresponding practical performance. In this article, based on a comprehensive review of fundamentals, principles and interconnected similarities of the MoX2 family, we focus on the structure-activity correlation of layered MoX2 for HER enhancement via hydrothermal synthesis. This method is summarized from different experimental systems to efficiently modulate the crystal structure and surface for boosted HER activity. Here, with the adjustment of three key experimental parameters: the categories of MoX2, reaction temperature and the molar amount of added reactants, the optimum HER performance can be obtained at the best conditions (MoSe2 species, 180℃ and a vast ratio of the reductant or metal precursor), and more microscopically, a controlled structure-activity relationship can be inducted. This summary may pave a new path for the controllable synthesis and modification of MoX2-based catalyst materials.

In this paper we study the prospects for casting light on this issue by future measurements of gravitational waves emitted during the inspirals and mergers of pairs of intermediate-mass black holes, discussing in particular the roles of prospective measurements by LISA and the proposed atom interferometers AION and AEDGE.

Characterizing disks can inform the formation environments of planets. To date, most imaging campaigns have probed the polarized light from disks, which is only a fraction of the total scattered light and not very sensitive to planetary emission. Aims. We aim to observe and characterize protoplanetary disk systems in the near-infrared in both polarized and total intensity light, to carry out an unprecedented study of the dust scattering properties of disks, as well as of any possible planetary companions. Methods. Using the star-hopping mode of the SPHERE instrument at the Very Large Telescope, we observed 29 young stars hosting protoplanetary disks and their reference stars in the Ks-band polarized light. We extracted disk signals in total intensity by removing stellar light using the corresponding reference star observations, by adopting the data imputation concept with sequential non-negative matrix factorization (DI-sNMF).

Specifically, herein, the heaviest of the two CP-even neutral Higgs states, H, can be the one discovered at the Large Hadron Collider (LHC) in 2012, with a mass of ≈ 125 GeV and couplings consistent with those predicted by the Standard Model (SM). In such a condition of the model, referred to as ‘inverted mass hierarchy’, the decay of the SM-like Higgs state into pairs of the lightest CP-even neutral Higgs boson, h, is possible, for masses of the latter ranging from MH/2 ≈ 65 GeV down to 15 GeV or so, all compatible with experimental constraints. In this paper, we investigate the scope of the LHC in accessing the process gg → H → hh → b ¯bτ τ by performing a Monte Carlo (MC) analysis aimed at extracting this signal from the SM backgrounds, in presence of a dedicated trigger choice and kinematic selection. We prove that some sensitivity to such a channel exists already at Run 3 of the LHC while the High-Luminosity LHC (HL-LHC) will be able to either confirm or disprove this theoretical scenario over sizable regions of its parameter space.

BUY Open Dirac-Majorana neutrino type conversion induced by an oscillating scalar dark matter Some properties of a neutrino may differ significantly depending on whether it is Dirac or Majorana type. The type is determined by the relative size of Dirac and Majorana masses, which may vary if they arise from an oscillating scalar dark matter. BUY Open Calculation of the Hubble Constant, the Minimum Mass, and the Proton Charge Radius Using the Dirac’s Hypothesis on the Ratio of the Electrostatic Force to the Gravitational Force This publication suggests that some physical values could be calculated using the Dirac’s hypothesis on the observed ratio of the electrostatic force to the gravitational force. The calculated value of the Hubble constant is H ≈ 72.013 km s‑1 Mpc‑1 and that of the minimum mass, Mmin ≈ 1.720 6 × 10‑68 kg. Recent observations suggest that the proton charge radius could also be calculated using an additional but related assumption: rp ≈ 0.826 4 fm. BUY Open Violation of γ in Brans-Dicke gravity The Brans Class I solution in Brans-Dicke gravity is a staple in the study of gravitational theories beyond General Relativity. Discovered in 1961, it describes the exterior vacuum of a spherical Brans-Dicke star and is characterized by two adjustable parameters. Surprisingly, the relationship between these parameters and the properties of the star has not been rigorously established. In this Proceeding, we bridge this gap by deriving the complete exterior solution of Brans Class I, expressed in terms of the total energy and total pressure of the spherisymmetric gravity source. BUY Open Tunable structure-activity correlations of molybdenum dichalcogenides (MoX2; X=S, Se, Te) electrocatalysts via hydrothermal methods: insight into optimizing the electrocatalytic performance for hydrogen generation Hydrogen Evolution Reaction (HER) has always gained wide attention as one of the eco-friendly and sustainable pathways for efficient hydrogen generation and storage; also, two-dimensional molybdenum dichalcogenide (MoX2, where X stands for S, Se, Te) BUY Open X-ray polarization properties of partially ionized equatorial obscurers around accreting compact objects We present the expected X-ray polarization signal resulting from distant reprocessing material around black holes. Using a central isotropic power-law emission at the center of the simulated model, we add distant equatorial and axially symmetric media that are covering the central accreting sources. We include partial ionization and partial transparency effects, and the impact of various polarization and steepness of the primary radiation spectrum. The results are obtained with the Monte Carlo code STOKES that considers both line and continuum processes and computes the effects of scattering and absorption inside static homogenous wedge-shaped and elliptical toroidal structures, varying in relative size, composition and distance to the source. We provide first order estimates for parsec-scale reprocessing in Compton-thin and Compton-thick active galactic nuclei, as well as winds around accreting stellar-mass compact objects. The resulting polarization can reach tens of % with either parallel or perpendicular orientation with respect to the axis of symmetry, BUY Open Unravelling multi-temperature dust populations in the dwarf galaxy Holmberg II Holmberg II – a dwarf galaxy in the nearby M81 group – is a very informative source of distribution of gas and dust in the interstellar discs. High-resolution observations in the infrared (IR) allows us to distinguish isolated star-forming regions, photodissociation (PDR) and HII regions, remnants of supernovae (SNe) explosions and, as such, can provide information about more relevant physical processes. In this paper we analyse dust emission in the wavelength range 4.5 to 160 𝜇m using the data from IR space observatories at 27 different locations across the galaxy. We observe that the derived spectra can be represented by multiple dust populations with different temperatures, which are found to be independent of their locations in the galaxy. By comparing the dust temperatures with the far ultraviolet (FUV) intensities observed by the UVIT instrument onboard AstroSat, we find that for locations showing a 100 𝜇m peak, the temperature of cold (20 to 30 K) dust grains show a dependence on the FUV intensities, while such a dependence is not observed for the other locations. We believe that the approach described here can be a good tool in revealing different dust populations in other nearby galaxies with available high spatial resolution data. BUY Open STeP-CiM: Strain-enabled Ternary Precision Computation-in-Memory based on Non-Volatile 2D Piezoelectric Transistors We propose 2D Piezoelectric FET (PeFET) based compute-enabled non-volatile memory for ternary deep neural networks (DNNs). PeFETs hinge on ferroelectricity for bit storage and piezoelectricity for bit sensing, exhibiting inherently amenable features for computation-in-memory of dot products of weights and inputs in the signed ternary regime. PeFETs consist of a material with ferroelectric and piezoelectric properties coupled with Transition Metal Dichalcogenide channel. We utilize (a) ferroelectricity to store binary bits (0/1) in the form of polarization (-P/+P) and (b) polarization dependent piezoelectricity to read the stored state by means of strain-induced bandgap change in Transition Metal Dichalcogenide channel. The unique read mechanism of PeFETs enables us to expand the traditional association of +P (-P) with low (high) resistance states to their dual high (low) resistance depending on read voltage. Specifically, we demonstrate that +P (-P) stored in PeFETs can be dynamically configured in (a) a low (high) resistance state for positive read voltages and (b) their dual high (low) resistance states for negative read voltages, without afflicting a read disturb. Such a feature, which we name as Polarization Preserved Piezoelectric Effect Reversal with Dual Voltage Polarity (PiER), is unique to PeFETs and has not been shown in hitherto explored memories. We leverage PiER to propose a Strain-enabled Ternary Precision Computation-in-Memory (STeP-CiM) cell with capabilities of computing the scalar product of the stored weight and input, both of which are represented with signed ternary precision. Further, using multi word-line assertion of STeP-CiM cells, we achieve massively parallel computation of dot products of signed ternary inputs and weights. Our array level analysis shows 91% lower delay and improvements of 15% and 91% in energy for in-memory multiply-and-accumulate operations compared to near-memory design approaches based on 2D FET based SRAM and PeFET respectively. We also analyze the system-level implications of STeP-CiM by deploying it in a ternary DNN accelerator. STeP-CiM exhibits 6.11× - 8.91× average improvement in performance and 3.2× average improvement in energy over SRAM based near-memory design. We also compare STeP-CiM to near-memory design based on PeFETs showing 5.67× - 6.13× average performance improvement and 6.07× average energy savings. BUY Open New method to revisit the gravitational lensing analysis of the Bullet Cluster using radio waves Gravitational lensing studies of the Bullet Cluster suggested convincingly in favour of the existence of dark matter. However, it was performed without the knowledge of the original orientation of each galaxy before gravitational lensing. A potential improvement to this issue lies in the measurement of the original orientation from the polarization direction of radio waves emitted from each galaxy. In this context, Francfort et al. derived a formula that can utilize the information about the original orientation of each galaxy to obtain what is called shear. However, we demonstrate that shear in their formula should be replaced by reduced shear when the change in sizes of images of galaxies is taken into account. As the previous gravitational lensing analysis of the Bullet Cluster used reduced shear, we suggest applying our improved formula directly for the reanalysis once we obtain the polarization direction of radio waves. In particular, we show that our new formula can yield a more accurate analysis than the previous one, if the polarization direction can be measured more precisely than 10◦.
