Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Vibration isolation performance and theoretical solution of periodic structure wave impeding block in layered transversely isotropic soil

open access: yesYantu gongcheng xuebao
Compared with traditional wave impeding block (WIB), periodic structure wave impeding block (PSWIB) exhibit inherent bandgap characteristics and can be tailored to isolate vibration waves at target frequencies; however, their performance in realistic ...

A New Approach in Designing Multi-Layer Frequency Selective Surfaces based on Tuning Pole-Zeros of Individual Layers [PDF]

open access: yesJournal of Intelligent Procedures in Electrical Technology, 2015
In this paper, a new approach (not new technique) is introduced for designing frequency selective surfaces (FSSs). We try to compose the desired frequency response using the frequency response of each constituent FSS.

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.

Matrix method of calculating the rescattering wave in a periodic structure

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
The method of recursive calculation of the characteristic matrix of the layered structure is developed. Analytical solutions for the matrix of second, third and fourth order describing the propagation of waves in periodic structures are found.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
