Five months into its unprecedented dismantling of foreign-aid programs,
the Trump administration has given the order to incinerate food instead of sending it to people abroad who need it.
Nearly 500 metric tons of emergency food

Within weeks, two of those sources told me, the food, meant for c…

Light PIDM in Warped Extra Dimensions
Traditional Planckian Interacting Dark Matter (PIDM), which interacts exclusively through gravity, typically requires heavy DM candidates (with mass $10^3-10^{15}$ GeV) and very high reheating temperature ($T_{\rm rh}\gtrsim 10^{15}$ GeV). In this article, we explore a novel realization of PIDM in warped five-dimensions, consisting of an "Ultra Violet"$-$"Dark"$-$"Infra Red" (UV-DB-IR) brane setup, where the DM can be a Dark brane composite light state with mass 1 MeV $-$ 1 TeV. The DM sector i…

Jack Ciattarelli, a former state legislator endorsed by Donald Trump won the Republican nomination quickly Tuesday evening. 
Rep. Mikie Sherrill, a former Navy pilot and federal prosecutor, won on the Democratic side, beating out five competitors.
New Jersey is one of two states, along with Virginia, hosting a high-stakes gubernatorial contest this year. 

New Jersey primaries: Trump-backed Ciattarelli wins GOP nod; Sherrill wins Dem nomination
Trump has jumped into the Garden State race, one of two gubernatorial elections this year that could serve as a pre-midterms referendum.

A Novel Hybrid Deep Learning Technique for Speech Emotion Detection using Feature Engineering
Nowadays, speech emotion recognition (SER) plays a vital role in the field of human-computer interaction (HCI) and the evolution of artificial intelligence (AI). Our proposed DCRF-BiLSTM model is used to recognize seven emotions: neutral, happy, sad, angry, fear, disgust, and surprise, which are trained on five datasets: RAVDESS (R), TESS (T), SAVEE (S), EmoDB (E), and Crema-D (C). The model achieves high accuracy on individual datasets, including 97.83% on RAVDESS, 97.02% on SAVEE, 95.10% for …

Unraveling the structure of $Λ$ hyperons with polarized $Λ\barΛ$ pairs
With data collected in a dedicated off-resonance scan within the center-of-mass energy range of 2.3864$-$3.0800 GeV, the BESIII collaboration provides the first complete energy-dependent measurements of the $Λ$ electromagnetic form factors in the time-like region. By combining double-tag and single-tag events from the $e^+e^- \to Λ\barΛ \to pπ^-\bar{p}π^+$ reaction, we achieve a complete decomposition of the spin structure of the reaction at five energy points, with high statistical and sy…

Correlation of Burst Behaviour with Magnetar Age
We analyze a wide set of historical magnetar burst observations detected with five different instruments, calibrating these to the energy range of Fermi-GBM observations for consistency. We find a striking correlation between a magnetar's characteristic age and both its typical burst energy and its burst activity level. Arguing that this bursting behaviour also correlates with true age, we interpret it as the result of a reducing high-stress volume of the crust in an aging magnetar: previous gi…

High-throughput viscometry via machine-learning from videos of inverted vials
Although the inverted vial test has been widely used as a qualitative method for estimating fluid viscosity, quantitative rheological characterization has remained limited due to its complex, uncontrolled flow - driven by gravity, surface tension, inertia, and initial conditions. Here, we present a computer vision (CV) viscometer that automates the inverted vial test and enables quantitative viscosity inference across nearly five orders of magnitude (0.01-1000 Pas), without requiring direct vel…

High resolution radio observations of the Chamaeleon star-forming region
We report on large-scale radio observations of the Chamaeleon star-forming region obtained with the Australia Telescope Compact Array (ATCA) that led to the definite detection of five young stars and the tentative detection of five more. As in other regions surveyed in the radio domain, the majority of detected sources are fairly evolved low-mass T Tauri stars, but we also detect one protostellar object (Ced 110 IRS4) and one Herbig Ae/Be star. With the exception of the protostellar source, the…

We present updated parameters for five-species air to be used with the Modified Marrone-Treanor (MMT) air dissociation model. The vibrational relaxation and chemical reaction rates are derived from quasiclassical trajectory calculation (QCT) and direct molecular simulation (DMS) using ab initio potential energy surfaces (PESs). The resulting model and parameter set enable efficient computational fluid dynamics (CFD) simulations of high-temperature nonequilibrium five-species air (N2, O2, NO, N …

Origin-Destination Travel Demand Estimation: An Approach That Scales Worldwide, and Its Application to Five Metropolitan Highway Networks
Estimating Origin-Destination (OD) travel demand is vital for effective urban planning and traffic management. Developing universally applicable OD estimation methodologies is significantly challenged by the pervasive scarcity of high-fidelity traffic data and the difficulty in obtaining city-specific prior OD estimates (or seed ODs), which are often prerequisite for traditional approaches. Our proposed method directly estimates OD travel demand by systematically leveraging aggregated, anonymiz…

Optical lever for broadband detection of fluid interface fluctuations
We exploit the optical lever principle to detect minute fluctuations of a liquid-air interface. Waves propagating on the interface deflect a specularly reflected laser beam, inducing angular deviations captured by a dual-element photodiode. We realise this principle in a compact set-up including a temperature-controlled fluid sample. Deflection angle fluctuations span five orders of magnitude in frequency, enabling detection of both low-frequency eigenmodes and high-frequency capillary waves dr…

We report a scalable and cost-effective method for fabricating high-performance Bragg mirrors using a bottom-up approach that combines evaporation-induced self-assembly (EISA) and dip-coating. The photonic crystals are composed of alternating mesoporous SiO$_2$ and dense TiO$_2$ layers, providing a high refractive index contrast ($\sim$0.8). This enables strong reflectance (up to 96%) with as few as five bilayers and precise control of the photonic stop band across the visible spectrum by simpl…

Revisiting color superconductors in bottom-up holography
We revisit the problem of constructing a color superconducting phase in bottom-up holography. We introduce a model that describes the five-dimensional dynamics of a scalar field dual to a chiral symmetry breaking condensate, which is coupled to the RR 4-form. The coupling is given by a topological WZ term, which is elegantly responsible both for scalar condensation at high density, and color Higgsing in the condensed phase. This construction realizes both properties at finite density and Higgsi…

Fast Luminous Extragalactic Transients in the VLA Sky Survey: Implications for the rates of Accretion-Induced Collapse Events, Fast Blue Optical Transients and Gamma Ray Burst Afterglows
Radio wavelengths offer a unique window into high-energy astrophysical phenomena that may be obscured or too rapidly evolving to be captured at other wavelengths. Leveraging data from the Very Large Array Sky Survey, we perform a systematic search for fast, luminous transients with characteristic timescales $\lesssim 3$ years in the nearby universe ($z \leq 0.3$). We report the discovery of five such transients, and classify them based on their synchrotron emission energetics and host galaxy pr…

We present Gemini/GHOST high-resolution spectra of five stars observed in two low surface brightness Milky Way satellites, Sagittarius II (Sgr2) and Aquarius II (Aqu2). For Aqu2, the velocities and metallicities of the two stars are consistent with membership in a dark matter-dominated ultra faint dwarf galaxy (UFD). The chemical abundance ratios suggest inefficient star formation from only one or a few supernovae (e.g., low Na, Sr, Ba), and enriched potassium (K) from super-AGB stars. For Sgr2…

Collective excitations in Hydrogen across the pressure-induced transition from molecular to atomic fluid
Dispersion of collective excitations in fluid Hydrogen along the isothermal line T=2500~K, including the region of molecular-to-atomis fluid transition, is studied by ab initio molecular dynamics (AIMD) simulations. The obtained density dependence of the adiabatic and high-frequency speed of sound contains a plateau in the region of the molecular-to-atomic fluid transition. We show, that the five-variable thermo-viscoelastic model of generalized hydrodynamics for pure molecular H$_2$ and pure a…

James Webb Space Telescope (JWST) has revealed a population of red and compact objects with a unique V-shape SED at z >= 4 known as Little Red Dots (LRDs). Most of the LRDs with existing spectral observations exhibit broad Balmer lines and are thus likely to host active galactic nuclei (AGNs). Here we present a study of LRDs with no broad H-alpha component. Our sample consists of five LRDs at z~5 with H-alpha line widths of about 250 km/s. They are selected from 32 LRDs that have NIRSpec high- …
