Length-scale cascade and spread rate of atomizing planar liquid jets

, 2018
The primary breakup of a planar liquid jet is explored via direct numerical simulation (DNS) of the incompressible Navier-Stokes equation with level-set and volume-of-fluid interface capturing methods.

Homeostatic Counter‐Regulation Mediates Spermidine‐Induced Triacylglyceride Reduction in Drosophila melanogaster—From Phenotype to Molecular Mechanism

The FASEB Journal, Volume 39, Issue 20, 31 October 2025.
In Drosophila melanogaster females fed a standard diet containing 2.5% yeast extract (low‐yeast diet), spermidine (Spd) administration does not enhance the endogenous Spd pool but increases the excretion of catabolic N1‐acetylspermidine (N1AcSpd) and reduces fat stores. This process requires the catabolic Akh/AkhR pathway.

Type I Outbursts in Low-eccentricity Be/X-Ray Binaries

, 2019
Type I outbursts in Be/X-ray binaries are usually associated with the eccentricity of the binary orbit. The neutron star accretes gas from the outer parts of the decretion disk around the Be star at each periastron passage. However, this mechanism cannot

Anti-Pseudomonas fluorescens mechanism of plantaricin Q7 from Lactiplantibacillus plantarum Q7 based on proteomics

Food Science of Animal Products
This study explored how plantaricin Q7 acts against Pseudomonas fluorescens at cellular and protein expression levels. Plantaricin Q7 exhibited a minimum inhibitory concentration (MIC) of 144 AU/mL against P. fluorescens. The scanning electron microscopy

A convergent expansion of the Airy's integral with incomplete Gamma functions

, 2020
There are two main power series for the Airy functions, namely the Maclaurin and the asymptotic expansions. The former converges for all finite values of the complex variable, $z$, but it requires a large number of terms for large values of $|z|$, and ...

Adversarial Spatio-Temporal Learning for Video Deblurring

, 2018
Camera shake or target movement often leads to undesired blur effects in videos captured by a hand-held camera. Despite significant efforts having been devoted to video-deblur research, two major challenges remain: 1) how to model the spatio-temporal ...

A Two-Dimensional Infrared Map of the Extrasolar Planet HD 189733b

, 2012
We derive the first secondary eclipse map of an exoplanet, HD 189733b, based on Spitzer IRAC 8 micron data. We develop two complementary techniques for deriving the two dimensional planet intensity: regularized slice mapping and spherical harmonic ...
