Since 1964, when I.A. Perov introduced the so-called generalized metric space where d(x,y) is an element of vector Rm, many researchers have considered various contractive conditions in this type space. In paper, we generalize, extend and unify some those established results. We are primarily concerned with examining existence a fixed point mapping from X to itself, but if (x,y) belongs relatio...

The purpose of this study was to assess the effects of contraction intensity, gender, and muscle on median frequency of the three superficial portions of the quadriceps femoris muscle. Thirty healthy volunteers were assessed for isometric electromyogram activity of the vastus medialis (VM), vastus lateralis (VL), and rectus femoris (RF) muscles with the knee at 60 degrees flexion. Subjects perf...

[Purpose] The purpose of this study was to investigate the effective strength levels of abdominal muscle contraction using the bracing contraction method. [Subjects] The experiment was conducted with 31 healthy male (M=15) and female (F=16) adults attending D University in Busan; all participants had less than obesity level BMI (BMI<30). [Methods] Bracing contraction was performed by the subjec...

In this paper, we prove some new fixed point theorems involving set-valued F-contractions in the setting of quasi-ordered metric spaces. Our results are significant since present Banach contraction principle a different manner from that which is known literature. Some examples and an application to existence solution Volterra-type integral equation given support obtained

Chemoattractants like f-Met-Leu-Phe (fMLP) induce neutrophils to polarize by triggering divergent signals that promote the formation of protrusive filamentous actin (F-actin; frontness) and RhoA-dependent actomyosin contraction (backness). Frontness locally inhibits backness and vice versa. In neutrophil-like HL60 cells, blocking phosphatidylinositol-3,4,5-tris-phosphate (PIP3) accumulation wit...

In this paper, we introduce a novel form of interpolative convex contraction and develop some new theorems by utilizing the progressive method contractions. We also obtain fixed point results for Suzuki in orbitally S-complete F-metric spaces. The second purpose research is to evaluate effectiveness approach solving fractional differential equations with boundary conditions.

In the present paper, we introduced concept of generalized multi-valued contraction mappings, via class functions \(\Phi\) and \(\Psi\) Also proved some fixed point results for (\(\phi\),\(\mathfrak{F}\))- mappings on cone b-metric spaces over Banach algebra \(\mathfrak{V}\). The conditions existence uniqueness are investigated. We give an example to support our main result.

Interactions of hormones stimulating and inhibiting uterine contraction were studied in vitro in uteri from oophorectomized rats. The beta-adrenergic effector, isoproterenol, a potent inhibitor of contraction, produced a dose-related increase of adenylate cyclase and accumulation of adenosine 3':5'-cyclic monophosphate (cAMP) that was inhibitable by propranolol. Oxytocin, which stimulates contr...
