The human gut microbiome across the life course

open access: yesFEBS 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.

Effects of slope and speed of escalator on the dispersion of cough-generated droplets from a passenger

open access: yes, 2021
During the pandemic of COVID-19, the public is encouraged to take stairs or escalators instead of elevators. However, the dispersion of respiratory droplets in these places, featured by slopes and human motion, is not well understood yet.

Parametric evaluation of 3D dispersion of rockfall trajectories [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2004
The capability of evaluating and managing rockfall related risks is largely based on numerical modelling. Nevertheless, the reliability and accuracy of rockfall models is greatly affected by the strong uncertainty and spatial variability which ...

Tunable dispersion slope compensator using novel tailored Gires-Tournois etalons [PDF]

open access: yes, 2004
We present a novel concept of tailored GTE structure and show that such devices are very useful for the realization of DSC with almost arbitrary dispersion profile and also with tunability in dispersion ...

Tunable dispersion and dispersion slope compensator using novel Gires-Tournois Bragg grating coupled-cavities

open access: yes, 2004
We report on the first realization of lattice-coupled all-fiber Gires-Tournois etalons for chromatic dispersion (CD) compensation. CD tunability is obtained by cascading two fiber Bragg grating superstructures.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Inverse scattering designs of dispersion-engineered single-mode planar waveguides

open access: yes
We use an inverse-scattering (IS) approach to design single-mode waveguides with controlled linear and higher-order dispersion. The technique is based on a numerical solution to the Gelfand-Levitan-Marchenko integral equation, for the inversion of ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Laser Field Distribution in Photonic Crystal Fiber With Triple Zero Dispersion Wavelengths [PDF]

open access: yesمجلة التربية والعلم, 1999
The aim of this work is to study the properties of the photonic crystal fibers (PCFs) and the laser field distribution at the zero dispersion wavelengths (ZDWs). Three PCFs are proposed, all the PCFs have one missing hole and one ring of holes around the
