A note on some applications of semi-open sets
International Journal of Mathematics and Mathematical Sciences, 1998 The object of the present paper is to study the well known notions of semi-closure, semiinterior, semi-frontier and semi-exterior of a set using the concept of semi-open sets. A semi-isolated point of a set is also defined and studied.

Intersection of Open Sets in the Reals
, 2023 We demonstrate that while the intersection of a finite number of open sets in $\mathbb R$ remains open in $\mathbb R$, the same cannot be universally said for intersections involving an infinite number of open sets.

\(\gamma\)-Semi-Open Sets and \(\gamma\)-Semi-Functions
Journal of Advanced Studies in Topology, 2012 Summary: In this paper, a new kind of set called a \(\gamma\)-semi-open set is introduced and investigated using the \(\gamma\)-operator due to Ogata. Such sets are used for studying new types of mappings, viz. \(\gamma\)-semi-continuous, \((\gamma,\beta)\)-semi-irresolute and weakly \(\gamma\)-semi-continuous.

FEBS Open Bio, EarlyView.Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells
FEBS Open Bio, EarlyView.RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells
FEBS Open Bio, EarlyView.To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

Science Journal of University of Zakho, 2013 In this paper we introduce a new concept of connectedness namely Sp-connected space. This class of spaces is strictly between semi-connectedness and connectedness. Several properties and characterizations of this concept are found.

Cocompact Open Sets and Continuity [PDF]
, 2012 Compact subsets of a topological space are used to define coc-open sets as new generalized open sets, and then coc-open sets are used to define (coc)∗-open sets as another type of generalized open sets.

International Journal of Mathematics and Mathematical Sciences, 1992 A property preserved under a semi-homeomorphism is said to be a semi-topological property. In the present paper we prove the following results: (1) A topological property P is semi-topological if and only if the statement (X,𝒯) has P if and only if (X,F ...
