Numerical range of an interval matrix [PDF]
, 2020 The numerical range of a matrix is a set of complex numbers that contains all the eigen- values of the matrix. It is used for instance to estimate a matrix norm. This thesis is about the numerical range of an interval matrix.

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.

The c-numerical range of tridiagonal matrices
, 2001 We give sufficient conditions for the c-numerical range of a tridiagonal matrix to be an elliptic disc, which generalize known results on the classical numerical ...

FEBS Letters, EarlyView.This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

The boundary of the numerical range
, 1975 This work includes two results which indicate a set theoretic relationship between the boundary of the numerical range and the essential numerical range. Several applications are derived.

Numerical ranges of Bargmann invariants
Physics Letters ABargmann invariants have recently emerged as powerful tools in quantum information theory, with applications ranging from geometric phase characterization to quantum state distinguishability. Despite their widespread use, a complete characterization of their physically realizable values has remained an outstanding challenge.

ON THE DIAMETER OF THE GENERALIZED NUMERICAL RANGE
Demonstratio Mathematica, 1997 The \(q\)-numerical range \(W_q (A)=\{\langle Ax,y\rangle: |x|= |y|=1\), \(\langle x, y\rangle=q\}\) provides a continuous passage from the disc \(W_0(A)\) to the classical numerical range \(W_1(A)\). Since \(\text{diam } W_0(A)\geq \text{diam } W_1(A)\), in general, it is natural to conjecture that the function \(q\mapsto \text{diam } W_q(A)\) is ...

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.

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