Article Abstract
Furukawa predicted that at late times, the domain growth in binary fluids scales as () ∼ , and the growth is driven by fluid inertia. The inertial growth regime has been highly elusive in molecular dynamics (MD) simulations. We perform coarsening studies of the ( = 3) Stockmayer (SM) model comprising of magnetic dipoles that interact long-range dipolar interactions as well as the usual Lennard-Jones (LJ) potential. This fascinating polar fluid exhibits a gas-liquid phase coexistence, and magnetic order even in the absence of an external field. From comprehensive MD simulations, we observe the inertial scaling [() ∼ ] in the SM fluid for an extended time window. Intriguingly, the fluid inertia is overwhelming from the outset - our simulations do not show the early diffusive regime [() ∼ ] and the intermediate viscous regime [() ∼ ] prevalent in LJ fluids.

The family Spinturnicidae belongs to the suborder Monogynapsida, superfamily Dermanyssoidea, and exclusively parasitizes the body surface of bats. In the present study, we determined the complete mitochondrial genome of Spinturnix psi, a species of bat mite, and subsequently conducted a comprehensive analysis of its genomic information. The mitochondrial genome of S.

Although several observational studies have suggested an association between plasma homocysteine (Hcy), vitamin B12, and folate levels and aortic diseases, including aortic dissection (AD), thoracic aortic aneurysm (TAA), and abdominal aortic aneurysm (AAA), the causality remains unclear. The aortic diameter was also included in the analysis. Therefore, this study employed Mendelian randomization (MR) analysis to investigate the effects of plasma Hcy, vitamin B12, and folate levels on aortic diseases.

In most eubacteria the initiator protein DnaA triggers chromosomal replication by forming an initiation complex at the origin of replication and also functions as a transcriptional regulator, coordinating gene expression with cell cycle progression. While DnaA-regulated genes are relatively well characterized in exponentially growing cells, its role in gene regulation during stationary phase remains insufficiently explored. Here, using an aquatic bacterium Caulobacter crescentus as a model, we show that C.

The ESCRT machinery mediates membrane remodeling in fundamental cellular processes including cytokinesis, endosomal sorting, nuclear envelope reformation, and membrane repair. Membrane constriction and scission is driven by the filament-forming ESCRT-III complex and the AAA-ATPase VPS4. While ESCRT-III-driven membrane scission is generally established, the mechanisms governing the assembly and coordination of its twelve mammalian isoforms in cells remain poorly understood.
