Genomic Insights into Post‐Domestication Expansion and Selection of Body Size in Ponies
Advanced Science, Volume 12, Issue 16, April 24, 2025.The authors’ research delves into the history of ponies by assembling a pony genome and integrating horse genomes. This unveils genetic connections between Asian and European pony breeds. Cis‐regulatory elements of key genes impacting body size are also identified.

Galactic Structures from Gravitational Radii
Galaxies, 2018 We demonstrate that the existence of a Noether symmetry in f ( R ) theories of gravity gives rise to an additional gravitational radius, besides the standard Schwarzschild one, determining the dynamics at galactic scales.

Dynamical Models of Elliptical Galaxies [PDF]
Symposium - International Astronomical Union, 1975 Self-consistent dynamical models of elliptical galaxies have been constructed using a modification of the Prendergast-Tomer algorithm. They reproduce many of the observed properties of elliptical galaxies.

The Magnetosphere‐Ionosphere‐Ground Responses to the May 2024 Super Solar Storm
Space Weather, Volume 23, Issue 4, April 2025.Abstract Earth suffered the attack of the strongest geomagnetic storm in the last 20 years (Kp = 9, Dst∼ ${\sim} $ −400 nT) occurred on 11 May 2024. Taking advantage of the LEO multi‐parameter CSES satellite (launched in 2018) with a large inclination angle 97° $97{}^{\circ}$, with the joint observations of NOAA and GOES, we present a comprehensive ...

The Open Journal of AstrophysicsAlignments of disc galaxies were thought to result from tidal torquing, where tidal field of the cosmic large-scale structure exert torquing moments onto dark matter haloes, determining their angular momentum and ultimately the orientation of galactic ...

A Photometric Study of Giant Ellipticals and Their Stellar Halos With VST
Galaxies, 2017 Observations of diffuse starlight in the outskirts of galaxies are thought to be a fundamental source of constraints on the cosmological context of galaxy assembly in the Λ CDM model.

Environmental Microbiology Reports, Volume 17, Issue 2, April 2025.The quorum sensing regulated sRNA Lrs1 participates in the adaptation of Pseudomonas aeruginosa in low iron by downregulating the siderophore pyochelin, the Quorum Sensing system PQS, and its associated virulence factor phenazines. ABSTRACT Iron is an essential nutrient for microbial growth. The opportunistic pathogen Pseudomonas aeruginosa can survive

Elliptical galaxies with separable potentials [PDF]
Monthly Notices of the Royal Astronomical Society, 1985 The perfect ellipsoid is presented: an inhomogeneous triaxial mass model with a gravitational potential that is of Stäckel form. The equations of motion are separable in ellipsoidal coordinates and all stellar orbits have three isolating integrals that are known explicitly.

Plant Pathology, Volume 74, Issue 3, Page 605-640, April 2025.The literature cites many alternative hosts of Phytophthora erythroseptica. However, evidence of host status is often insufficient, thus a polyphasic approach (morphological, molecular, histological and pathogenicity) is required. ABSTRACT Most published studies of Phytophthora erythroseptica, the major causal agent of pink rot of potato, have focused ...

SIMULATIONS OF LARGE-SCALE GASEOUS STRUCTURES WITH SPH
Odessa Astronomical Publications, 2017 A computer programme based on the 3D SPH approach is described. Some numerical results are presented: the formation of gaseous ring around an SO galaxy due to the stripping of a gas-rich donor system.
