FEBS 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 ...

Control Sets and Total Positivity
Semigroup Forum, 2004 The goal of this paper is to connect two different mathematical subjects, namely totally positive matrices and control sets. The set \(T\) of totally positive matrices in \(Sl(d,\mathbb{R})\) (subgroup of determinant one matrices of size \(d \times d\)) is also a semigroup with non-empty interior in \(Sl(d,\mathbb{R})\).

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.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Total positivity from a kind of lattice paths
, 2023 Total positivity of matrices is deeply studied and plays an important role in various branches of mathematics. The main purpose of this paper is to study total positivity of a matrix $M=[M_{n,k}]_{n,k}$ generated by the weighted lattice paths in $\mathbb{

Coherence Matrix Estimation With Total Positivity Regularization for Interferometric Phase Linking
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingInterferometric phase linking has become a critical step in distributed scatterer interferometry, yet its performance is significantly affected by inaccuracies in the coherence matrix and its inverse, such as the precision matrix.

FEBS 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 ...

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Total positivity criteria for partial flag varieties [PDF]
, 2011 For a simply-connected complex algebraic group G of type A, D, or E, we prove (see C. Geiss et al. (2008) [12], Conjecture 19.2) a new family of total positivity criteria for partial flag varieties G/P, where P is a parabolic subgroup of ...
