Is sleep affected after microgravity and hypergravity exposure? A pilot study
Journal of Sleep Research, Volume 34, Issue 2, April 2025.Summary Sleep is known to be affected in space travel and in residents of the international space station. But little is known about the direct effects of gravity changes on sleep, if other factors, such as sleep conditions, are kept constant. Here, as a first exploration, we investigated sleep before and after exposure to short bouts of microgravity ...

Periodontology 2000, EarlyView.Abstract Background Extracellular vesicles (EVs), especially exosomes, are nanoparticles increasingly recognized as key regulators of intercellular communication in both physiological and pathological aspects. Despite rapid progress, inconsistencies in nomenclature, isolation, and characterization continue to restrict translational advancement.

Numerical Solution of Parabolic Equations by the Box Scheme [PDF]
, 1973 The box scheme proposed by H. B. Keller is a numerical method for solving parabolic partial differential equations. We give a convergence proof of this scheme for the heat equation, for a linear parabolic system, and for a class of nonlinear parabolic ...

Advanced Materials, Volume 38, Issue 52, 16 September 2026.Hydration‐induced symmetry breaking transforms layered LiInP2S6${\rm LiInP}_2{\rm S}_6$ from a nonpolar to a chiral‐polar phase, producing a giant enhancement of non‐resonant second‐harmonic generation. The reversible tuning of polar order through molecular intercalation establishes a strategy for dynamically controlling nonlinear optical ...

Locally parabolic subgroups in Coxeter groups of arbitrary ranks [PDF]
, 2012 Despite the significance of the notion of parabolic closures in Coxeter groups of finite ranks, the parabolic closure is not guaranteed to exist as a parabolic subgroup in a general case.

Numerical Aspects of Turbulent Blood Flow in Aorta: A Systematic Review
Engineering Reports, Volume 8, Issue 9, September 2026.The aim of this systematic review is to systematize the methodological approaches used in the state‐of‐the‐art literature, including the choice of turbulence models, validation methods, as well as the identification of the main hemodynamic parameters characterizing turbulent flow.

Avoiding maximal parabolic subgroups of S k
Discrete Mathematics & Theoretical Computer Science, 2000 We find an explicit expression for the generating function of the number of permutations in S n avoiding a subgroup of S k generated by all but one simple transpositions.

A Top-Down Account of Linear Canonical Transforms
Symmetry, Integrability and Geometry: Methods and Applications, 2012 We contend that what are called Linear Canonical Transforms (LCTs) should be seen as a part of the theory of unitary irreducible representations of the '2+1' Lorentz group.

The oscillatory response of the electroretinogram and neuronal adaptation
Acta Ophthalmologica, Volume 104, Issue 6, Page 616-637, September 2026.Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.
