Tropical totally positive cluster varieties [PDF]
, 2022 We study the relation between the integer tropical points of a cluster variety (satisfying the full Fock-Goncharov conjecture) and the totally positive part of the tropicalization of an ideal presenting the corresponding cluster algebra.

Molecular Oncology, EarlyView.Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Intraventricular solitary fibrous tumor
Chinese Journal of Contemporary Neurology and Neurosurgery, 2015 Background Solitary fibrous tumor (SFT) is a mesenchymal neoplasm of specialized fibroblastic lineage, which frequently occurs in the subcutaneous and deep soft tissue of pleura,mediastinum, head and neck, extremities and trunk.

On the boundary of totally positive upper triangular matrices [PDF]
, 1995 Let B+ ⊂ GLn (R) denote the subgroup of upper triangular n × n matrices with positive entries on the main diagonal. A matrix M ∈ B+ is called totally positive if the determinants of all its minors not containing a row or column lying completely under the

FEBS Open Bio, EarlyView.Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

A probabilistic representation of totally positive matrices [PDF]
, 1986 C. Loewner (Math. Z. 63 (1955), 338–340) has shown that every non-singular totally positive matrix of finite order can be reached from the identity by forward solutions of the control equation dRdt = C(t)R, when C(t) varies in the class of Jacobi ...

FEBS Open Bio, EarlyView.In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

The totally nonnegative completion problem
, 1998 An n-by-n real matrix is said to be totally positive (nonnegative) if every minor (principal and non-principal) is positive (nonnegative). The totally nonnegative completion problem asks which partially totally nonnegative matrices have a completion to a

Totally positive functions and totally bounded functions on [−1, 1] [PDF]
, 1988 A function ƒ on [−1, 1] is said to be totally positive if all its Lagrange interpolants are positive on [−1, 1]. It is said to be totally bounded if there is a uniform bound on all its Lagrange interpolants on [−1, 1].
