Semigroups of Transformations Preserving an Equivalence Relation and a Cross-Section [PDF]
Communications in Algebra, 2004 Abstract For a set X, an equivalence relation ρ on X, and a cross-section R of the partition X/ρ induced by ρ, consider the semigroup T(X, ρ, R) consisting of all mappings a from X to X such that a preserves both ρ (if (x, y) ∈ ρ then (xa, ya) ∈ ρ) and R (if r ∈ R then ra ∈ R).

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 ...

ANALISIS LAYER SYSTEM BAMBU LAMINASI BERDASARKAN PENYEBARAN KERAPATAN IKATAN PEMBULUHNYA
Jurnal Ilmu Pertanian Indonesia, 2013 Anatomically, bamboo is constructed from many types of cells. Vascular bundles are the cells which give the highest contribution to the bamboo strength, thus the density distribution of vascular bundles could be used as the main variable for analyzing ...

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers
Molecular Oncology, EarlyView.This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

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.

Head nurse ethical competence and transformational leadership: a cross-sectional study
BMC NursingEthical competency is important to head nurses' transformational leadership, however, few researches have explored their correlation, Additionally, most studies used variable-oriented approach to examine ethical competence, without considering it as a multidimensional concept.
