Reduction of a pair of matrices to a special triangular form over a ring of almost stable range 1 (in Ukrainian) [PDF]
Математичні Студії, 2012 In the paper it is considered a notion of a ring of almost stable range 1. It is shown that an arbitrary pair of matrices over commutative Bezout domain of almost stable range 1, where at least one of the matrices is not a zero divisor, reduced to a ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Tree-Ring Evidence for Great Plains Drought
, 2001 A new collection of tree-ring chronologies developed from trees and remnant material located in the western and central Great Plains makes an important contribution to the spatial coverage of the US tree- ring chronology network.

Ringed Spaces of Valuation Rings over Hilbert Rings
Tokyo Journal of Mathematics, 1995 Soit \((X, {\mathcal O}_X)\) un espace annelé, on lui associe l'espace annelé \((W, {\mathcal O}_W)\) où \(W\) est l'ensemble des points fermés de \(X\) et \({\mathcal O}_W\) la restriction de \({\mathcal O}_X\) à \(W\). Réciproquement, à un espace annelé \((W, {\mathcal O}_W)\) on associe l'espace annelé \(t(W, {\mathcal O}_W)\) de ses ensembles ...

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells
Molecular Oncology, EarlyView.This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

A Guide to Measuring Tree-Ring Widths
, 1979 Dendrochronologists in their scientific inquiries use quantitative data, of which tree-ring widths form a major part. In order to gather the necessary quantitative tree-ring data, someone must be trained to measure the widths of the tree rings.

Molecular Oncology, EarlyView.Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Tree-Ring Research in Semi-Arid West Africa: Need and Potential
, 2002 High-resolution paleoclimatic data for West Africa are needed to provide context for contemporary climatic and ecological dynamics. Six hundred trees (22 botanical families, 43 genera and over 70 species) from semi-arid West Africa were evaluated for ...
