A sufficient condition for matrix stability

open access: yes, 1974
An n by n complex matrix A is said to be positive stable if Re (A) > 0 for each eigenvalue (lambda) of A. If A satisfies both of the following two conditions, then A is positive stable: (1) for each k = 1, .. . ,n , the real part of the sum of the k by k

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

open access: yesMolecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Multiplicative maps on generalized \(n\)-matrix rings

open access: yesCubo
Let \(\mathfrak{R}\) and \(\mathfrak{R}'\) be two associative rings (not necessarily with identity elements). A bijective map \(\varphi\) of \(\mathfrak{R}\) onto \(\mathfrak{R}'\) is called an \textit{\(m\)-multiplicative isomorphism} if {\(\varphi (x_ ...

Matrix measures and random walks [PDF]

open access: yes
In this paper we study the connection between matrix measures and random walks with a tridiagonal block transition matrix. We derive sufficient conditions such that the blocks of the n-step transition matrix of the Markov chain can be represented as ...

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

open access: yesMolecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Safety of Matrix-M–adjuvanted COVID-19, seasonal influenza, combination influenza-COVID-19, and malaria vaccines: a review of the evidence

open access: yesExpert Review of Vaccines
Introduction The saponin-based Matrix-M adjuvant induces potent and durable immunity through producing long-lasting memory B-cells and broad-based T-cell immunity, across a variety of vaccine platforms.

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

Stability of one-step and linear multistep methods - a matrix technique approach

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
We investigate the stability of one-step and linear multistep methods from a new direction. Our aim is to modify the long and technical proof which is consequently omitted in almost every textbook and make it user-friendly.

A generalization of Tyler's M-estimators to the case of incomplete data [PDF]

open access: yes
Many different robust estimation approaches for the covariance or shape matrix of multivariate data have been established until today. Tyler's M-estimator has been recognized as the 'most robust' M-estimator for the shape matrix of elliptically symmetric

TOWARDS M-MATRIX [PDF]

open access: yes, 2018
This book belongs to a series of online books summarizing the recent state Topological Geometrodynamics (TGD) and its applications. TGD can be regarded as a unied theory of fundamental interactions but is not the kind of unied theory as so called GUTs constructed by graduate students at seventies and eighties using detailed recipes for how to reduce ...
