Advanced Intelligent Systems, EarlyView.This article proposes a lightweight YOLOv4‐based detection model using MobileNetV3 or CSPDarknet53_tiny, achieving 30+ FPS and higher mAP. It also presents a ShuffleNet‐based classification model with transfer learning and GAN‐augmented images, improving generalization and accuracy.

Signature of the interaction between dark energy and dark matter in observations
, 2010 We investigate the effect of an interaction between dark energy and dark matter upon the dynamics of galaxy clusters. This effect is computed through the Layser-Irvine equation, which describes how an astrophysical system reaches virial equilibrium and ...

Logarithmic and Strong Coupling Models in Weyl‐Type f(Q,T)$f(Q,T)$ Gravity
Annalen der Physik, EarlyView.This work explores Weyl‐type f(Q,T) gravity using recent observational datasets — CC, Pantheon+, Union 3.0, and DESI DR2. Through MCMC analysis of logarithmic and strong coupling models, the study reveals a transition from deceleration to acceleration, quintessence‐to‐phantom dynamics, and late‐time consistency with LCDM, offering a geometry‐driven ...

Batteries &Supercaps, EarlyView.Cycling water‐in‐salt batteries involves complex degradation processes that require multiprobe analysis. Using online electrochemical mass spectrometry (OEMS), postmortem X‐ray photoemission spectroscopy (XPS) (including hard‐XPS), and scanning electron microscopy (SEM), the degradation mechanisms are examined in composite electrodes (TiS2 and LiFePO4)

Cosmological Phase Transitions—EWPT-QCDPT: Magnetic Field Creation
Magnetochemistry, 2022 We review the cosmic microwave background (CMBR) estimate of ordinary matter, dark matter and dark energy in the universe. Then, we review the cosmological electroweak (EWPT) and quantum chromodynamics (QCDPT) phase transitions.

Constraining the Dark Matter decay lifetime with very deep observations of the Perseus cluster with the MAGIC telescopes [PDF]
, 2015 We present preliminary results on Dark Matter searches from observations of the Perseus galaxy cluster with the MAGIC Telescopes. MAGIC is a system of two Imaging Atmospheric Cherenkov Telescopes located in the Canary island of La Palma, Spain.

Polar Disk Galaxies as new way to study galaxy formation: the case of NGC4650A
, 2010 NGC4650A is a polar disk galaxy: this is a peculiar object composed by a central spheroidal component, the host galaxy (HG), and an extended disk made up by gas, stars and dust, which orbits nearly perpendicular to the plane of the central galaxy.

European Journal of Heart Failure, EarlyView.Graphical overview of derivation and testing of multiparametric trajectories of cardiac function. This study identified six trajectories of LV systolic and diastolic function from mid‐ to late‐life. Predicted trajectory from single echocardiogram identified four trajectories at differential risk for HFpEF and HFrEF.

Food Frontiers, EarlyView.Transcriptomics revealed the metabolism of Lactiplantibacillus plantarum during soy milk fermentation. The fermentation of soy milk released aroma compounds and health‐beneficial metabolites. ABSTRACT The fermentation of plant‐based beverages, such as organic and locally produced soy juice (SJ), offers a sustainable way to develop dairy alternatives ...
