On some strongly regular relations on hyperrings

, 2018
In this paper first by the fact that the relation $ ^*$ is the transitive closure of two its subrelations we introduce and analyze a binary relation $ ^*_e$ on a hyperring such that the derived ring is a unitary ring. Next we introduce and study the notion of $ _e$-parts in a hyperring and we characterize $ _e$-parts in a $ _e$-strong hyperring $R$

On(strongly) regular relations on soft topological hypergroups

Filomat
In the first step, we determine some conditions for having a topological complete hypergroup by defining the geometric space obtained from each strongly regular relation. Then applying set theory, we introduce the concepts of ?soft geometric spaces,? ?soft topological hypergroups,? and ?(strongly) regular relations? on soft hypergroups.

Physical Exercise Affects Adipose Tissue Profile and Prevents Arterial Thrombosis in BDNF Val66Met Mice

Cells, 2019
Adipose tissue accumulation is an independent and modifiable risk factor for cardiovascular disease (CVD). The recent CVD European Guidelines strongly recommend regular physical exercise (PE) as a management strategy for prevention and treatment of CVD ...

Selenium deficiency is linearly associated with hypoglycemia in healthy adults

Redox Biology, 2020
Objective: The trace element selenium (Se) is needed for regular biosynthesis of selenoproteins, which contribute to antioxidative defense systems and affect redox-regulated signaling.

Viscosity Methods of Asymptotically Pseudocontractive and Asymptotically Nonexpansive Mappings for Variational Inequalities

Abstract and Applied Analysis, 2012
Let {𝑡𝑛}⊂(0,1) be such that 𝑡𝑛→1 as 𝑛→∞, let 𝛼 and 𝛽 be two positive numbers such that 𝛼+𝛽=1, and let 𝑓 be a contraction. If 𝑇 be a continuous asymptotically pseudocontractive self-mapping of a nonempty bounded closed convex subset 𝐾 of a real reflexive ...

Serum visfatin in chronic renal failure patients on maintenance hemodialysis: A correlation study

The Egyptian Journal of Internal Medicine, 2013
Background and aim of work Endothelial dysfunction, atherosclerosis, and cardiovascular disease are strongly linked to chronic kidney disease. It has been hypothesized that visfatin may play an important role in uremia-related atherosclerosis and the ...

Diversity and Distribution Patterns of Hard Bottom Polychaete Assemblages in the North Adriatic Sea (Mediterranean)

Diversity, 2020
The knowledge on the hard bottom polychaete assemblages in the Northern Adriatic Sea, a Mediterranean region strongly affected by environmental pressures, is scarce and outdated.

A generalized Ramanujan-Nagell equation related to certain strongly regular graphs

Integers : Electronic Journal of Combinatorial Number Theory, 2014
Summary: A quadratic-exponential Diophantine equation in 4 variables, describing certain strongly regular graphs, is completely solved. Along the way we encounter different types of generalized Ramanujan-Nagell equations whose complete solution can be found in the literature, and we come across a problem on the order of the prime ideal above 2 in the ...

Towards monitoring biodiversity in Amazonian forests: how regular samples capture meso-scale altitudinal variation in 25 km2 plots.

PLoS ONE, 2014
BackgroundEcological monitoring and sampling optima are context and location specific. Novel applications (e.g. biodiversity monitoring for environmental service payments) call for renewed efforts to establish reliable and robust monitoring in ...
