IMPORTANCE Prophylactic gastrostomy tube (GT) insertion prior to chemoradiotherapy is a valuable nutritional adjunct in patients with head and neck cancer undergoing nonsurgical treatment. However, concerns have been expressed regarding high rates of GT dependence. There is little information in the literature regarding the impact of modifiable risk factors such as smoking and alcohol consumpti...

Does prosody help word recognition? In this paper, we propose a novel probabilistic framework in which word and phoneme are dependent on prosody in a way that improves word recognition. The prosody attribute that we investigate in this study is the duration lengthening effects of the speech segments in the vicinity of intonational phrase boundaries. Explicit Duration Hidden Markov Model (EDHMM)...

The statistics of sea state duration (persistence) have been found to be dependent upon the recording interval ∆t. Such behavior can be explained as a consequence of the fact that the graph of a time series of an environmental parameter such as the significant wave height has an irregular, “fractal” geometry. The mean duration τ can have a power-law dependence on ∆t as ∆t → 0, with an exponent ...

conclusions the results of this study in terms of personality disorders and types of used drugs were in accordance with the previous studies results. it is necessary to design appropriate treatment plans for medical treatment of those with personality disorders. results there was a significant correlation between stimulant use and histrionic personality disorder (p < 0.001) and antisocial and n...

Adaptation aftereffects are the tendency to perceive an ambiguous target stimulus, which follows an adaptor stimulus, as different from the adaptor. A duration dependence of face adaptation aftereffects has been demonstrated for durations of at least 500ms, for identity related judgments. Here we describe the duration dependence of the adaptation aftereffects of very brief (11.7ms-500ms) backwa...

The duration and ionic dependence of action potentials are developmentally regulated. Voltage-clamp recordings of amphibian spinal neurons have revealed alterations in five currents. To determine whether the changes in the currents are sufficient to produce the change in action potential duration and ionic dependence, we constructed a Hodgkin-Huxley model of electrical excitability of these neu...

This work describes a cryogenic, electro-optically -switched Yb:YAG laser that generates 114-W average TEM power with 47% optical-to-optical efficiency. Pulse repetition frequency is 5 kHz, pulse duration is 16 ns full-width at half-maximum, and is less than 1.05.

We propose a new method for creating an optimal coherence in a two-level system (TLS) based on adiabatic following. Optimal coherence is achieved by choosing the time-dependent phase of the pulse that provides vanishing field-TLS detuning dðtÞ at central time when the pulse amplitude reaches maximum. For example, dðtÞ 1⁄4 d0ð1 expððt t0Þ=s0ÞÞ for t 6 t0 and d 1⁄4 0 for t > t0. The pulse envelop...
