The first boundary-value problem for the telegraph equation in area with mobile border

open access: yesVìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2010
The first boundary-value problem for the telegraph equation on an interval whichone end is mobile is considered. The method of the solution of such problem is developed and its exact solution is obtained. This method is based on integrated representation

Inflammation potentiates miR-939 expression and packaging into small extracellular vesicles

open access: yesJournal of Extracellular Vesicles, 2019
Extracellular RNA in circulation mediates intercellular communication in normal and pathological processes. One mode of circulating miRNA transport in bodily fluids is within 30–150 nm small extracellular vesicles (sEVs) or exosomes.

Coronary Serum Exosomes Derived from Patients with Myocardial Ischemia Regulate Angiogenesis through the miR-939-mediated Nitric Oxide Signaling Pathway

open access: yesTheranostics, 2018
Rationale: Angiogenesis is a crucial step towards tissue repair and regeneration after ischemia. The role of circulating exosomes in angiogenic signal transduction has not been well elucidated. Thus, this study aims to investigate the effects of coronary

The boundedness of commutators associated with Schrödinger operators on Herz spaces

open access: yesJournal of Inequalities and Applications, 2016
Let L = − Δ + V $L=-\Delta+V$ be a Schrödinger operators on R n $\mathbb{R}^{n}$ , n ≥ 3 $n\geq3$ , where the nonnegative potential V belongs to the reverse Hölder class B s $B_{s}$ for s > d 2 $s>\frac{d}{2}$ . Let T β = ( − Δ + V ) − β V β $T_{\beta}=(-

Enumerative classification systems: development, usage and examples [PDF]

open access: yes, 2012
Klasifikacijom dijelimo, razvrstavamo predmete, pojave, pojmove i slično prema unaprijed definiranim kriterijima. To je aktivnost i pojam koji se susreće u svim sferama života, pa tako i informacijskim znanostima.

Decreased expression of miR-939 contributes to chemoresistance and metastasis of gastric cancer via dysregulation of SLC34A2 and Raf/MEK/ERK pathway

open access: yesMolecular Cancer, 2017
The development of chemoresistance and metastasis are the leading causes of death for gastric cancer (GC) patients, however, the molecular mechanisms involved remain unclear.

A Mizoguchi–Takahashi Type Fixed Point Theorem in Complete Extended b-Metric Spaces

open access: yesMathematics, 2019
In this paper, we prove a new fixed point theorem for a multi-valued mapping from a complete extended b-metric space U into the non empty closed and bounded subsets of U, which generalizes Nadler’s fixed point theorem.

Controlling Chaos—Forced van der Pol Equation

open access: yesMathematics, 2017
Nonlinear systems are typically linearized to permit linear feedback control design, but, in some systems, the nonlinearities are so strong that their performance is called chaotic, and linear control designs can be rendered ineffective.
