[Purpose] The purpose of this study was to clarify the validity of salivary α-amylase as a method of quickly estimating anaerobic threshold and to establish the relationship between salivary α-amylase and double-product breakpoint in order to create a way to adjust exercise intensity to a safe and effective range. [Subjects and Methods] Eleven healthy young adults performed an incremental exerc...

Double light pulse resolution required longer inter-pulse time intervals of short duration of the pulse. The threshold of double pulse discrimination was not contingent upon the actual phase of cardiac or respiratory cycle.

We show that p = √ e n is a sharp threshold for the random graph Gn,p to contain the square of a Hamilton cycle. This improves the previous results of Kühn and Osthus and also Nenadov and Škorić.

We show that the threshold for the random graph Gn,p to contain the square of a Hamilton cycle is p = 1 √ n . This improves the previous results of Kühn and Osthus and also Nenadov and Škorić.

Transmembrane activity was recorded from canine false tendons bathed with Tyrode's solution at 37°C. Stimulus patterns provided a 3-second pause after every ten beats. Acetylstrophanthidin was infused at concentrations up to 2 X 10~ g/ml. One or two transient depolarizations (TDs) followed the last driven response of each series. The appearance of TDs was associated with depression of normal ph...

background: dna isolation procedure can significantly influence the quantification of dna by real time pcr specially when cell free dna (cfdna) is the subject. to assess the extraction efficiency, linearity of the extraction yield, presence of co-purified inhibitors and to avoid problems with fragment size relevant to cfdna, development of appropriate external dna control (edc) is challenging. ...

Introduction: Opposite observations about the discrepancy in the pain perception between male and female has been reported. In this regard, pain thresholds among male and female rats in different phases of oestrous cycle were evaluated via tail immersion test. In addition, efficiency of alcoholic extract of datura stramonium as an analgesic plant in the modulation of acute pain threshold has be...

The evolution of the cavitation noise (CN) spectra in field a focusing emitter with an increase intensity ultrasound (US) was studied. Spectra without subharmonics f 0 /2 were recorded for first time, where is frequency generating cavitation,. Such spectrum observed partially degassed water at high duty cycle ultrasonic pulses. threshold appearance sonoluminescence (SL) coincides CR spectrum. I...

We fabricated coplanar homojunction a-IGZO TFTs that are highly stable under AC and DC bias-temperature-stress. For TFTs of the size W/L = 60μm/10μm, the stress-induced threshold voltage shifts are all within -0.35 V. A comprehensive investigation of AC BTS stress polarity, pulse width, and duty cycle dependence is presented. We find that higher frequency of bipolar AC pulses increases the devi...

2-D threshold function f is a function defined on the integer interior of a rectangular area [0, m] × [0, n] on a plane and takes values from the set {0, 1} such that there is a straight line separating the pre-images f −1 (0) and f −1 (1). For the number of such functions only asymptotic bounds were known. We give an exact formula for the number of 2-D threshold functions and derive an asympto...
