A STAR FORMATION LAW FOR DWARF IRREGULAR GALAXIES [PDF]

open access: yesThe Astrophysical Journal, 2015
The radial profiles of gas, stars, and far ultraviolet radiation in 20 dwarf Irregular galaxies are converted to stability parameters and scale heights for a test of the importance of two-dimensional (2D) instabilities in promoting star formation. A detailed model of this instability involving gaseous and stellar fluids with self-consistent thicknesses

Stellar population of the irregular galaxy IC 10 [PDF]

open access: yesAstronomy Letters, 2009
Based on our observations with the 6-m BTA telescope at the Special Astrophysical Observatory, the Russian Academy of Sciences, and archival Hubble Space Telescope images, we have performed stellar photometry for several regions of the irregular galaxy IC 10, a member of the Local Group.

An ATP‐Mediated Antibiotic β‐Peptide Nanofiber That Kills Multidrug‐Resistant Bacteria via a Multistage Mechanism

open access: yesAdvanced Science, Volume 13, Issue 28, 18 May 2026.
The 3K‐AP system forms infinite supramolecular fibrils that undergo controlled degradation into shorter fragments upon enzymatic hydrolysis. Multitechnique imaging reveals a stepwise bacteriolytic mechanism involving bacterial entrapment, disassembly into lethal constructs, and associated extracellular vesicle release, highlighting the dynamic ...

The Stellar Content of 10 Dwarf Irregular Galaxies [PDF]

open access: yesThe Astronomical Journal, 1998
We examine the stellar content of 10 dwarf irregular galaxies of which broad-band CCD photometry was published in Hopp & Schulte-Ladbeck (1995). We also present Halpha images for several of these galaxies. The galaxies in the sample are located outside of the Local Group.

Spatial Analysis of Tropical Cyclone Precipitation Through Landfall: A Multi‐Basin Perspective

open access: yesMeteorological Applications, Volume 33, Issue 3, May/June 2026.
We use a shape metric methodology to analyze the spatial evolution of tropical cyclone (TC) precipitation across the North Indian, Western Pacific, and North Atlantic basins. Across all basins, precipitation area decreases from pre‐landfall to post‐landfall, with closure decreasing and dispersion increasing, indicating an exposed TC center and outward ...

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model

open access: yesSystems Research and Behavioral Science, Volume 43, Issue 3, Page 1212-1228, May/June 2026.
ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

Evaluating the Color of Chocolate Chip Cookies: Comparative Performance of Instrumental Colorimetry, Digital Image Analysis, and Computer Vision Relative to Human Perception

open access: yesJournal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT Food color is commonly quantified using colorimeters; however, these instruments may be impractical in home‐based or small‐scale production settings. More accessible alternatives, such as digital image analysis and computer vision, may offer reliable color quantification when conventional instrumentation is unavailable.

CI chondrite Oued Chebeika 002 links asteroids Bennu and Ryugu to common parent body

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 5, Page 801-818, May 2026.
Abstract CI chondrites are a compositionally primitive group of meteorites that have undergone extensive aqueous alteration, providing insights into the evolution of primitive planetesimals. Oued Chebeika 002 is the most pristine CI chondrite to date.
