Amoeboid motility requires spatiotemporal coordination of biochemical pathways regulating force generation and consists of the quasi-periodic repetition of a motility cycle driven by actin polymerization and actomyosin contraction. Using new analytical tools and statistical methods, we provide, for the first time, a statistically significant quantification of the spatial distribution of the tra...

the aim of this short note is to introduce the concepts of prime and semiprime ideals in ordered ag-groupoids with left identity. these concepts are related to the concepts of quasi-prime and quasi-semiprime ideals, play an important role in studying the structure of ordered ag-groupoids, so it seems to be interesting to study them.

let r be a ring,  be an endomorphism of r and mr be a -rigid module. amodule mr is called quasi-baer if the right annihilator of a principal submodule of r isgenerated by an idempotent. it is shown that an r-module mr is a quasi-baer module if andonly if m[[x]] is a quasi-baer module over the skew power series ring r[[x; ]].

Introduction: It was shown in a previous study, that MCPIP, a cilostamide derivative, increased atrial contraction force without changing contraction rate. To improve this property, two new derivatives of cilostamide were synthesized and their effects on PDE3 activity and isolated rat atria contraction were investigated. Methods: The inhibitory effect of each compound on PDE3 enzyme was dete...

In this Letter, we perform a detailed analysis of the M5.5-class eruptive flare occurring in active region 12929 on 2022 January 20. The eruption hot channel generates fast coronal mass ejection (CME) and dome-shaped extreme-ultraviolet (EUV) wave at speeds 740$-$860 km s$^{-1}$. CME is associated with type II radio burst, implying that EUV fast-mode shock wave. During impulsive phase, shows qu...

We study the relationship between functional inequalities for a Markov kernel on metric space X and of transportation distances probability measures P(X). Extending results Luise Savaré Hellinger–Kantorovich contraction particular case heat semigroup an RCD(K,∞) space, we show that more generally, such are equivalent to reverse Poincaré inequalities. also adapt “dynamic dual” formulation distan...

This study aims to design vibration isolators, using two types of coil springs with different hysteresis, and evaluate the isolation performance each design. Vibration is achieved through nonlinear spring characteristics isolators an origami-inspired foldable structure attached spring, which have quasi-zero stiffness. However, exhibited load-displacement curves between expansion contraction pro...

We study the behavior of conformally symplectic systems near rotational Lagrangian tori. We recall that conformally symplectic systems appear for example in mechanical models including a friction proportional to the velocity. We show that in a neighborhood of these quasi–periodic solutions (either transitive tori of maximal dimension or periodic solutions), one can always find a smooth symplect...

in this paper we investigate decompositions of submodules in modules over a proufer domain into intersections of quasi-primary and classical quasi-primary submodules. in particular, existence and uniqueness of quasi-primary decompositions in modules over a proufer domain of finite character are proved. proufer domain; primary submodule; quasi-primary submodule; classical quasi-primary; decomposi...

For a class of quasi-contractive operators defined on an arbitrary Banach space, it has been shown that the Picard iteration technique converges faster than the Mann iteration technique. In this paper we make a comparison of the Picard and Mann iterations with respect to their convergence rate for a more general class of operators called quasi-contractions in metrizable topological vector space...
