Potential Spectral Tuning of the Tapetum Lucidum in a Broadly Distributed Ungulate

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The tapetum lucidum, a biological reflector system found in the eyes of many vertebrate species, enhances visual sensitivity in low light conditions by reflecting light back through the retina. The structure of the ungulate tapetum fibrosum is unique, and its reflectance varies temporally in reindeer (Rangifer tarandus).

ATAC‐seq in Emerging Model Organisms: Challenges and Strategies

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Principle of ATAC‐seq (left), overview of arthropod species with published ATAC‐seq data (middle), summary of experimental design (right). ABSTRACT The Assay for Transposase‐Accessible Chromatin with sequencing (ATAC‐seq) is a versatile and widely utilized method for identifying potential regulatory regions, such as promoters and enhancers, within a ...

COSMOS-Web: The Role of Galaxy Interactions and Disk Instabilities in Producing Starbursts at z < 4

open access: yesThe Astrophysical Journal
We study of the role of galaxy–galaxy interactions and disk instabilities in producing starburst activity in galaxies out to z = 4. For this, we use a sample of 387 galaxies with robust total star formation rate measurements from Herschel, gas masses ...

Interacting Galaxies with MOND

open access: yes, 2007
We compare N-body simulations performed in MOND with analogs in Newtonian gravity with dark matter (DM). We have developed a code which solves the Poisson equation in both gravity models. It is a grid solver using adaptive mesh refinement techniques, allowing us to study isolated galaxies as well as interacting galaxies.

Bar-spheroid interaction in galaxies

open access: yesThe Astrophysical Journal, 1992
The secular evolution of barred galaxies is explored using N-body simulation and linear analysis. In particular, we examine the interaction between bars and spheroidal components of galaxies. According to our calculations, this interaction drives secular transfer of angular momentum from bars to spheroids, primarily through resonant coupling.

Anti‐Pseudomonas Aeruginosa Bacteriophage Loaded Electrospun Fibers for Antibacterial Wound Dressings

open access: yesMacromolecular Rapid Communications, Volume 46, Issue 13, July 04, 2025.
Multidrug resistant Pseudomonas (P.) aeruginosa is detected in many infected wounds and is challenging to treat with antibiotics. As an alternative, this work incorporates anti‐P. aeruginosa Neko phages into electrospun fibres to explore their potential for treating infected wounds.

Behavioural and physiological responses of chacma baboons (Papio ursinus) to human‐induced mortality in anthropogenically modified habitat

open access: yesPeople and Nature, EarlyView.
Abstract As a result of expanding human populations and the anthropogenic modification of natural habitats, many wildlife populations are living in increasing proximity to humans. While this may provide benefits to some species through increased access to resources, sharing space and resources often leads to negative interactions or ‘conflict’ between ...

Astronomical Image Superresolution Reconstruction with Deep Learning for Better Identification of Interacting Galaxies

open access: yesThe Astrophysical Journal Supplement Series
Galaxy–galaxy mergers are crucial in galaxy evolution, but the tidal features around galaxies are often faint, making it difficult to identify interacting or merging galaxies.

Tidal Interaction of Galaxies

open access: yesThe Astrophysical Journal Supplement Series, 1978
In this paper we investigate the effect of weak tidal interactions among galaxies in clusters. We obtain the Fokker-Planck coefficients for this process by making use of the impulse approximation. We assume that the outer regions of a galaxy are well described by isotropically distributed stellar orbits with small angular momenta.

On the characteristics of tidal structures of interacting galaxies

open access: yes, 2011
We present the results of our analysis of the geometrical tidal tail characteristics for nearby and distant interacting galaxies. The sample includes more than two hundred nearby galaxies and about seven hundred distant ones.
