Vision Transformer‐Enhanced Multi‐Descriptor Approach for Robust Age‐Invariant Face Recognition

Applied AI Letters, Volume 6, Issue 3, October 2025.
ABSTRACT This study presents a robust age‐invariant face recognition framework, addressing challenges posed by age‐related facial variations. Evaluated on the FGNet and Morph II datasets, the system integrates Viola‐Jones for face detection, SIFT and LBP for feature extraction, and Vision Transformers (ViTs) for global feature representation.

Evidence for Large-scale, Rapid Gas Inflows in z ∼ 2 Star-forming Disks

The Astrophysical Journal, 2023
We report high-quality H α /CO imaging spectroscopy of nine massive (log median stellar mass = 10.65 M _⊙ ) disk galaxies on the star-forming main sequence (henceforth SFGs), near the peak of cosmic galaxy evolution ( z ∼ 1.1–2.5), taken with the ESO ...

Identifying the Effects of Fish and Rhizosphere on the Structure of the Planktonic Bacterial Communities and Resistome in an Aquaponics Recirculation Loop

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
These results suggest that fish traits drive planktonic microbial communities. Rhizosphere seems to act as a mitigation factor on microbial communities and the relative abundance of detectable Antibiotic Resistance Genes. ABSTRACT Since they are saving resources, recirculating aquaculture systems (RAS) are perceived as a viable production strategy ...

Galaxy rotation curves and dissipation

The Astrophysical Journal, 1989
Une theorie est proposee pour expliquer la tendance des galaxies a disque a manifester des vitesses rotationnelles constantes en considerant l'hypothese suivant laquelle la dissipation d'energie est le facteur principal qui determine les formes finales des galaxies a disque.

galkin: A new compilation of Milky Way rotation curve data

SoftwareX, 2017
We present galkin, a novel compilation of kinematic measurements tracing the rotation curve of our Galaxy together with a tool to treat the data. The compilation is optimised to Galactocentric radii between 3 and 20 kpc and includes the kinematics of gas,

Role of Gaseous Disk in the Formation of the Spiral Structure of the Milky Way Galaxy

Open Astronomy, 2016
We use observational gaseous and stellar density distributions in the disk of the Milky Way (MW) galaxy together with the disk rotation curve and measured disk velocity dispersion to build collisionless and combined collisionless-gaseous equilibrium ...

Skeletal Muscle Mitochondria Contain Nuclear‐Encoded RNA Species Prior to and Following Adaptation to Exercise Training in Rats

The FASEB Journal, Volume 39, Issue 13, 15 July 2025.
Here, we report that mitochondria from rat skeletal muscle contain a select population of nuclear‐encoded protein‐coding and noncoding RNAs, including 3 microRNAs whose expression tended to be altered by exercise training. These findings suggest that mitochondria‐localized nuclear‐encoded RNAs may play a role in mediating the beneficial adaptive ...

Diverse Rotation Curves of Galaxies in a Simulated Universe: The Observed Dependence on Stellar Mass and Morphology Reproduced

The Astrophysical Journal
We use the IllustrisTNG cosmological hydrodynamical simulation to study the rotation curves of galaxies in the local universe. To do that, we first select the galaxies with 9.4

Impact of Fatty Acid Carbon Chain Length and Protein Composition on Physicochemical and Digestive Properties of MFGM Contained Emulsions

Food Science &Nutrition, Volume 13, Issue 7, July 2025.
Emulsions prepared by OPO (long‐chain fatty acids) exhibited the largest average particle size and greater stability compared to those with medium‐chain fat (coconut oil) and ultra‐long‐chain fat (DHA algae oil). When whey protein and casein were added in a 6:4 ratio, the effect of fatty acid carbon chain length on the average particle and the ...

On the Rotation Curve of Disk Galaxies in General Relativity

The Astrophysical Journal, 2022
Abstract Recently, it has been suggested that the phenomenology of flat rotation curves observed at large radii in the equatorial plane of disk galaxies can be explained as a manifestation of general relativity (GR) instead of the effect of dark matter (DM) halos.
