Variation of the High-mass Slope of the Stellar Initial Mass Function: Theory Meets Observations
The Astrophysical Journal, 2023 We present observational evidence of a correlation between the high-mass slope of the stellar initial mass function (IMF) in young star clusters and their stellar surface density, σ _* .

Advanced Science, EarlyView.Mechanisms of Fatty Infiltration and Muscle Degeneration. Clinical metadata identified intramuscular fat accumulation as an independent driver of muscle mass decline. Single‐nucleus RNA sequencing of spinal sarcopenia muscle revealed adipogenic reprogramming of fibro‐adipogenic progenitors, satellite‐cell niche disruption, and elevated levels of the ...

The Influence of Common Language on the Trade of Wheat and Bakery Products
Agribusiness, EarlyView.ABSTRACT This study examines whether sharing a common official language increases the probability that two countries engage in bilateral trade of wheat and bakery products. Using a binary choice framework applied to 54,780 country‐pair observations for 2023, probit and logit models of the extensive margin of trade are estimated, with a focus on whether

Frontiers in Astronomy and Space SciencesMultiple Transpolar arcs (MTPAs) are distinct auroral phenomenon occurring in the high-latitude ionosphere under prolonged northward interplanetary magnetic field (IMF) conditions. While the evolution of MTPAs is thought to be mainly modulated by the IMF

Food Security Strategy, Macroeconomic Dynamics and Food Import Sensitivity in Qatar
Agribusiness, EarlyView.ABSTRACT Qatar has limited agricultural land and water resources and therefore remains highly dependent on food imports. This structural dependency makes Qatar vulnerable to external shocks such as the recent Gulf crisis, threatening food security and disrupting global supply chains. In response to previous shocks, Qatar started implementing a National

SWMF simulation of field-aligned currents for a varying northward and duskward IMF with nonzero dipole tilt [PDF]
Annales Geophysicae, 2008 This study concentrates on the FACs distribution for the varying northward and duskward interplanetary magnetic field (IMF) conditions when the dipole tilt is nonzero. A global MHD simulation (the Space Weather Modeling Framework, SWMF) has been used

Advanced NanoBiomed Research, EarlyView.Schematic representation of acellular matrix generation from human uterine fibroblast cells, coating on polycaprolactone electrospun nanofibers, and subsequent in vitro and in vivo characterization. A tissue‐engineered scaffold tailored for uterine myometrium‐specific regeneration is designed. The electrospinning technique was used to fabricate aligned
