The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Polarization singularities in paraxial vector fields: morphology and statistics [PDF]
, 2002 Polarization patterns in the transverse plane generically contain singularities: points of circular polarization (C points), lines of linear polarization (L lines), instantaneous zeros (disclinations) and component zeros.

Dynamics of P. L. Chebyshev’s paradoxical mechanism [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. ИнформатикаThe paradoxical mechanism of P. L. Chebyshev is the main issue of this article. The paradoxical mechanism could be considered as the union of the lambda-mechanism and a double pendulumthe free vertices of which are hingedly connected. One of the pendulum

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Pairs of geometric foliations of regular and singular surfaces [PDF]
, 2010 We examine some generic features of surfaces in the Euclidean 3-space $\mathbb{R}^3$ related to the Gauss map on the surface. We consider these features on smooth surfaces and on singular surfaces with a cross-cap singularity.

Basic study on the characteristics of a singular mechanism and its application to the robot arm
Nihon Kikai Gakkai ronbunshu, 2019 This paper shows a singular mechanism for a gravity compensated and reactionless robot arm. Firstly, the difference between singular point and singular mechanism is explained.

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Concerning marginal singularities in the boundary-layer flow on a downstream-moving surface [PDF]
, 1996 The formation of separation singularities in solutions of the classical boundary-layer equations is studied numerically and analytically for the case of a two-dimensional incompressible steady flow near a solid surface moving in the direction of the main
