Six primary (Ia) and seven secondary (II) muscle spindle afferents and eight Golgi tendon organ afferents (Ib) from the tibial anterior muscle of the cat, recorded at the dorsal roots, were subjected to a sinusoidal stretch of the host muscle, the frequency of which increased linearly from 2 to 80 Hz over four different lengths of time. Both the amplitude of the sinusoidal stretch and the prest...

The authors present the central capacity sharing (CCS) model and derive equations describing its behaviors to explain results from dual-task situations. The predictions of the CCS model are contrasted with those of the central bottleneck model. The CCS model predicts all of the hallmark effects of the psychological refractory period (PRP) pardigm: -1 slope of the PRP effect at short stimulus on...

Stimuli that are clearly positive or negative (hence valence-laden stimuli) have the potential to interrupt unrelated task processing. A typical example is the emotional Stroop effect (ESE) in which responding to a certain task feature (e.g., color) is delayed by the presentation of task-irrelevant valent stimuli (e.g., negative pictures) compared to valence-neutral stimuli. Here we scrutinize ...

Abstract OBJECTIVES: Several approaches have been proposed for the treatment of carpal tunnel syndrome (CTS) based on its severity. The aim of this study is to determine the optimal management for severe CTS.  METHODS: This study was conducted in a cross-sectional fashion during a 22-month period from August 2017 to June 2019 in a referral rehabilitation clinic in southern Iran. A total of 11...

BACKGROUND The purpose of this study was to investigate the effect of latency on the development of bone lengthening force and bone mineralization during mandible distraction osteogenesis. METHODS Distraction tensions were investigated at different latency period in 36 rabbits using internal unilateral distractor. Strain gauges were prepared and attached to the distractor to directly assess t...

Broadcasting plays an important role in the communication protocol design and it acts as a fundamental operation in wireless sensor network (WSN). This paper investigates the Minimum Latency Broadcast Scheduling Duty Cycled (MLBSDC) problem in WSN performing scheduling with minimum collision. The MLBSDC problem aims to find a broadcast scheduling that minimizes the time in which the last node r...

professional firefighting is among the most demanding jobs. prior studies have showed the notable prevalence of poor sleep quality among professional firefighters that may result in catastrophes. the aim of this study was in field confirmation of zolpidem usage (10 mg/po/bed time) for short term management of poor sleeps quality among professional firefighters. in a double-blind, randomized, pl...

Abstract. Given a doubling measure μ on R, it is a classical result of harmonic analysis that Calderón-Zygmund operators which are bounded in L(μ) are also of weak type (1, 1). Recently it has been shown that the same result holds if one substitutes the doubling condition on μ by a mild growth condition on μ. In this paper another proof of this result is given. The proof is very close in spirit...

A change in subtask order in the psychological refractory period (PRP) paradigm increases the effect of stimulus onset asynchrony (SOA) on the second response. We used a paradigm with cued, randomly determined subtask order to test the hypothesis that this SOA by order switch overadditivity reflects order control, via "copying" stimulus order. In Experiments 1a and 1b, overadditivity was eviden...

Introduction: Excessive olivo-cerebellar burst-firing occurs during harmaline-induced tremor. We hypothesized that antiglutamatergic agents would suppress harmaline tremor. From this point of view, the aim of current study was to investigate the effects of riluzole on harmaline-induced tremor in rat. Material and Methods: Four groups of Wistar rats weighing 80–100 g were injected with harmaline...
