Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit
ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs
A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Age‐related trends in niche position and specialization in Neotropical vertebrates
Species' niche positions and breadths within a region's environmental space, measured through ecological niche factor analysis (ENFA) as marginality and specialization, can reflect evolutionary constraints related to lineage age. The ‘internal incumbency' hypothesis predicts that older species, due to competitive preemption, occupy more central niche ...

A local bifurcation theorem for C1-Fredholm maps
A local bifurcation theorem is proved under standard transversality assumptions by means of a reduction to finite dimensions. The Krasnosel'skii Bifurcation Theorem is generalized to C 1 - Fredholm maps. Let X and Y be Banach spaces, F: R x X —> Y be C 1

Ultrafast oscillations in the human brain and their functional significance
Abstract Objective The upper frequency limit of human brain activity remains unknown. Using ultrahigh sampling rate (≥20 kHz) intracranial microelectroencephalography, this study aimed to systematically explore and quantitatively characterize brain field oscillations beyond the established high‐frequency oscillation range (>2 kHz), and to determine ...

This study presents a cross‐tissue, single‐cell/single‐nucleus transcriptomic atlas spanning from prenatal to postnatal developmental stages in pig, characterizing 83 distinct cell types from 252,033 cells. Through the construction of cross‐tissue transcriptional regulatory networks and pseudotime trajectories, we revealed that organogenesis is driven ...

Single‐cell RNA‐seq of normal and endometritis endometrium shows reduced epithelial cells and fate divergence toward ferroptosis or ribosome/antigen‐presentation programs. COL1A1+ epithelial cells act as an AP‐1–driven hub that enhances VEGFA–VEGFR signaling and remodels the vascular microenvironment.
