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.

Interpretable Topic Extraction and Word Embedding Learning Using Non-Negative Tensor DEDICOM
Machine Learning and Knowledge Extraction, 2021 Unsupervised topic extraction is a vital step in automatically extracting concise contentual information from large text corpora. Existing topic extraction methods lack the capability of linking relations between these topics which would further help ...

Factorizations for a class of multivariate polynomial matrices [PDF]
Multidimensional Systems and Signal Processing, 2019 Following the works by Lin et al. (Circuits Syst. Signal Process. 20(6): 601-618, 2001) and Liu et al. (Circuits Syst. Signal Process. 30(3): 553-566, 2011), we investigate how to factorize a class of multivariate polynomial matrices. The main theorem in this paper shows that an $l\times m$ polynomial matrix admits a factorization with respect to a ...

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.

Inherited LU-factorizations of matrices
Linear Algebra and its Applications, 2007 Assume that \(A\) is an \(n\times n\) matrix with entries in a ring \(\mathcal{R}\) and that \(a_{11}, a_{22},\dots,a_{nn}\) are invertible elements in \(\mathcal{R}\). Write \(A=B+D+C\) where \(B\) is strictly lower triangular, \(C\) is strictly upper triangular, and \(D\) is diagonal. The authors consider various factorizations containing \(B\), \(D\)

On Symmetric Factorizations of Hankel Matrices
2023 IEEE 64th Annual Symposium on Foundations of Computer Science (FOCS), 2023 We present two conjectures regarding the running time of computing symmetric factorizations for a Hankel matrix $\mathbf{H}$ and its inverse $\mathbf{H}^{-1}$ as $\mathbf{B}\mathbf{B}^*$ under fixed-point arithmetic. If solved, these would result in a faster-than-matrix-multiplication algorithm for solving sparse poly-conditioned linear programming ...

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

On the Spectral Form Factor for Random Matrices
Communications in Mathematical Physics, 2023 AbstractIn the physics literature the spectral form factor (SFF), the squared Fourier transform of the empirical eigenvalue density, is the most common tool to test universality for disordered quantum systems, yet previous mathematical results have been restricted only to two exactly solvable models (Forrester in J Stat Phys 183:33, 2021.

Coprime Factorization with J All-Pass Denominator: The Noncanonical Case
, 1999 Given an arbitrary rational matrix G, we are interested to construct the class of coprime factorizations of G with J-all pass denominators of McMillan degree as small as possible.
