OBJECTIVES To evaluate the anaesthetic properties and tolerance of articaine versus lidocaine at equal vasoconstrictor concentration. STUDY DESIGN A total of 96 male and female patients who underwent surgical treatment of the lower third molar participated. Patients were randomly assigned to articaine hydrochloride with epinephrine 1:100,000 and lidocaine hydrochloride with epinephrine 1:100,...

in this study, generation of the transient evoked ooacoustic emissions in human ear has been simulated using a new electroacoustic model. the method of state variables was adopted to calculate the auditory model, and numerical integration methods have been used to solve differential equations in matlab. simulation results have been compared with the real data. in this study, latency curves, fre...

INTRODUCTION High intensity cutaneous stimulus transiently suppresses tonic voluntary muscle activity resulting in cutaneous silent period (CSP). AIM The aim of our study was to evaluate the normal values of an onset latency L1, a late latency L2 and a duration of CSP after stimulating sensory fibres of the median nerve. MATERIAL AND METHODS This prospective study was performed at the Neuro...

We extended and tested the MITRE real-time embedded scalable high performance computing benchmarking concept by implementing the RT_2DFFT benchmark on the MasPar MP-X series of massively parallel processors (MPPs). The RT_2DFFT benchmark specifies a symmetric two-dimensional fast Fourier transform (FFT) within a real-time software test bench. The test bench provides the realistic stimulus for t...

Background Traditional scheduling models give poor support for the design of multithreaded control systems. One difficulty lies in the nonlinearity in dynamic scheduling mechanisms such as rate-monotonic or earliest-deadline-first scheduling: a small change in a task parameter, e.g. period, execution time, deadline, priority, etc., may give rise to unpredictable results in terms of input-output...

Behavioral and electrophysiological evidences have shown that locus ceruleus (LC) is involved in different tasks including modulation of sensory processing and shift of attention. In the present study, single unit responses of barrel cortical cells was recorded following controlled mechanical displacement of the principal and peripheral vibrissae in adult rats (100 trials of 200 µm deflection f...

Introduction: The rapid development of wireless telecommunication technologies over the past decades, has led to significant changes in the exposure of the general public to electromagnetic fields. Nowadays, people are continuously exposed to different sources of electromagnetic fields such as mobile phones, mobile base stations, cordless phones, Wi-Fi routers, and power lines. Therefore, th...

In this paper we present a Markov Chain model for TCP congestion avoidance phase. With this model we are able to analyze congestion window behavior as a discrete-time stochastic process and distinguish between window transient period and steady state. Using this result we are able to obtain more accurate estimate of TCP latency over lossy links compared to existing models. We then simplify the ...

Radiation-induced sarcoma usually develops after an interval of more than 10 years from the completion of radiation therapy to the diagnosis of secondary sarcoma. However, the theory of radiation-induced transformation does not rule out postirradiation sarcomas with a short latency period. We experienced the case of a patient with postirradiation leiomyosarcoma of the tongue, which occurred 19 ...
