In 2006, I. Beg and M. Abbas have studied the existence of coincidence and common fixed points for two mappings satisfying a weak contractive condition. Their results were extended in 2008 by A. Azam and M. Shakeel to the case of three mappings. Recently M. Abbas and D. Dorić employed the contractive conditions introduced in [Q. Zhang and Y. Song, Fixed point theory for generalized φ-weak contr...

Very recently, Proinov introduced a great family of contractions in the setting complete metric spaces that has attracted attention many researchers because very weak conditions are assumed on involved functions. Inspired by Proinov’s results, this paper, we introduce new class fuzzy (in sense George and Veeramani) able to translate framework best advantages abovementioned auxiliary Accordingly...

The influence of noradrenergic mechanisms involved in micturition in spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats was investigated using continuous cystometry in in vivo and in vitro studies on isolated bladder and urethral tissues. Compared with WKY rats, SHR had a significantly lower bladder capacity (SHR: 0.7 +/- 0. 05 ml; WKY rats: 1.3 +/- 0.06 ml; P < 0.001), micturiti...

Cortical correlate of the Piper rhythm in humans. J. Neurophysiol. 80: 2911-2917, 1998. The electromyogram (EMG) of healthy humans demonstrates a tendency to rhythmic oscillations at around 40 Hz (the Piper rhythm) during strong voluntary contraction. Why motor units should discharge synchronously locked to such a high-frequency is unclear. We recorded whole scalp magnetoencephalographic (MEG) ...

‎‎Many authors such as Amini-Harandi‎, ‎Rezapour ‎et al., ‎Kadelburg ‎et al.‎‎, ‎have tried to find at least one fixed point for quasi-contractions when $alphain[frac{1}{2}‎, ‎1)$ but no clear answer exists right now and many of them either have failed or changed to a lighter version‎. In this paper‎, ‎we introduce some new strict fixed point results in the set of multi-valued '{C}iri'{c}-gener...

PURPOSE To evaluate and correlate the amplitude of esophageal contractions triggered by swallowing water with dynamic extension and habitual, strong and weak sound intensity in total laryngectomees wearing a tracheoesophageal prosthesis. METHODS Thirty total laryngectomees using tracheoesophageal voice with a phonatory prosthesis were evaluated by measuring the amplitude of contractions in th...

The effect of local drop of wall stiffness in pressurized waterways on the pressure wave speed and the wave attenuation during transients is investigated experimentally. A new signal-processing procedure to identify the presence of a weak reach is introduced and validated by physical experimentation based on assessing the pressure and vibration records acquired at both ends of a multi-reach ste...
