The parametric coupling between large amplitude magnetic field-aligned circularly polarized electromagnetic ion-cyclotron (EMIC) waves and ponderomotively driven ion-acoustic perturbations in magnetized space plasmas is considered. A cubic nonlinear Schrödinger equation for the modulated EMIC wave envelope is derived, and then solved analytically. The modulated EMIC waves are found to be stable...

Telocyte (TC) is a newly identified type of cell in the cardiac interstitium (www.telocytes.com). TCs are described by classical transmission electron microscopy as cells with very thin and long telopodes (Tps; cellular prolongations) having podoms (dilations) and podomers (very thin segments). TCs' three-dimensional (3D) morphology is still unknown. Cardiac TCs seem to be particularly involved...

Background. This article evaluates correction of rib hump in patients with idiopathic thoracic scoliosis who had been treated by the Cotrel-Dubousette method. Material and methods. We investigated 35 patients pre- and postoperatively in this study. Back surface measurements were studied pre- and postoperatively using our own device. Scoliosis correction was assessed by comparing pre- and postop...

A pothole is an open crack developed on roads owing to varied climatic situations and exposure heavy-load trucks. Potholes are acting as one of the major causes accidents economic loss in repair vehicles. Hence this paper proposes a detection system that assists drivers avoiding potholes road by providing prior warnings using YOLOV7 machine learning technique. The warning can be like buzzer whi...

SIR—The concept of ‘frailty’ has been used to identify older adults at increased risk for disability [1, 2]. A major obstacle to developing primary prevention strategies for frailty is the lack of clinical markers of early frailty, especially among high functioning older adults. The Physical Performance Battery (PPB) has been reported to predict disability in older adults [3, 4], but its associ...

This paper studies the global structure of set nodal solutions a generalized Sturm–Liouville boundary value problem associated to quasilinear equation$ -(\phi(u'))' = \lambda u + a(t)g(u), \quad \lambda\in {\mathbb R}, $where $ a(t) is non-negative with some positive humps separated away by intervals degeneracy where a\equiv 0 $. When \phi(s) s this equation includes prototype classical model g...

OBJECTIVE To explain a reduction in pedestrian-motor vehicle crashes in Arkhangelsk, Russia, in 2005-2010. STUDY DESIGN Retrospective ecological study. METHODS For 2005-2010, police data on pedestrian-motor vehicle crashes, traffic violations, and total motor vehicles (MVs) were combined with data on changes in national road traffic legislation and municipal road infrastructure. Negative bi...

PURPOSE The objective of this study was to describe spatial and temporal parameters during gait in pregnant women, and to compare it with women in post-partum and with a control group. METHODS To investigate alteration in natural locomotion, we used an electronic walkway (GAITRite system). Fifty-eight pregnant women (four last months of pregnancy), nine post-partum women and twenty-three heal...
