Some properties of totally positive matrices [PDF]
, 1976 Let A be a real n × n matrix. A is TP (totally positive) if all the minors of A are nonnegative. A has an LU-factorization if A = LU, where L is a lower triangular matrix and U is an upper triangular matrix. The following results are proved: Theorem 1: A

Molecular Oncology, EarlyView.CIN85 is highly expressed in osteosarcoma, particularly in metastatic lesions. Its overexpression increases cell migration and Matrigel invasion, while silencing CIN85 suppresses these behaviors. Transcriptome analysis shows that CIN85 regulates MMP2, COL3A1, and Akt/mTOR signaling. Targeting these pathways reverses CIN85‐induced motility, highlighting

An Interlacing Property of Eigenvalues of Strictly Totally Positive Matrices [PDF]
, 1998 . We prove results concerning the interlacing of eigenvalues of principal submatrices of strictly totally positive matrices. x1. Introduction The central results concerning eigenvalues and eigenvectors of strictly totally positive (STP) matrices were ...

Molecular Oncology, EarlyView.Here, we demonstrate that HS1BP3 interacts with Cortactin through a proline‐rich region (PRR3.1) and show that this interaction, and HS1BP3 itself, promote cancer cell proliferation and invasion. Inhibition of this interaction leads to build‐up of TKS5 in multivesicular endosomes and altered secretion of CD63 and CD9, providing an explanation for the ...

Matrices totally positive relative to a tree, II [PDF]
, 2016 If T is a labelled tree, a matrix A is totally positive relative to T , principal submatrices of A associated with deletion of pendent vertices of T are P-matrices, and A has positive determinant, then the smallest absolute eigenvalue of A is positive ...

Interpreting the effects of DNA polymerase variants at the structural level
Molecular Oncology, EarlyView.Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

Lattice -ordered matrix rings over totally ordered rings [PDF]
, 2014 For an nxn matric algebra over a totally ordered integral domain, necessary and sufficient conditions are derived such that the entrywise lattice order on it is the only lattice order (up to an isomorphism) to make it into a lattice ordered algebra in ...

On bounded ratios of minors of totally positive matrices [PDF]
, 2023 We provide several examples of bounded Laurent monomials of minors of a totally positive matrix, which can not be factored into a product of so called primitive ratios, thus showing that the conjecture about factorization of bounded ratios stated in [3 ...
