Value chain is the value-added process resulting from extension of rural tourism industry chain. Its direction construction includes vertical service field, and combination horizontal regional elements. The value (TVC) closely related to transformation elements production, life, ecology, culture, which helps promote high-quality development implementation in China. Using Dalishu village as an e...

BACKGROUND The effectiveness of emergency medical interventions can be best evaluated using time-to-event statistical methods with time-varying covariates (TVC), but this approach is complicated by uncertainty about the actual times of death. We therefore sought to evaluate the effect of hospital intervention on mortality after penetrating trauma using a method that allowed for interval censori...

In this paper, a new thermodynamic cycle for power and fresh water production is presented, which includes MED-TVC desalinations Allam cycles due to the important influence they have on electric industry in controlling limiting greenhouse emissions. First, analyzed appropriate location heat-extraction identified produce required vapor desalination system. It was determined that heat site suitab...

Serum lipids were measured in children and their parents from 40 families in which the father had a myocardial infarction or coronary heart disease (CHD) before age 40 years. The relationship between physical activity and serum lipid concentrations in the children was also evaluated. Twenty six men had one or more abnormal lipid value (in mmol/l): total venous cholesterol (TVC) > 6.24, triglyce...

Hypoperfusion of active skeletal muscle elicits a reflex pressor response termed the muscle metaboreflex. Our aim was to determine the muscle metaboreflex threshold and gain in humans by creating an open-loop relationship between active muscle blood flow and hemodynamic responses during a rhythmic handgrip exercise. Eleven healthy subjects performed the exercise at 5 or 15% of maximal voluntary...

It has been suggested that the arterial baroreflex and muscle metaboreflex are both activated during heavy exercise and that they interact to modulate primary cardiovascular reflex responses. This proposed interaction and its consequences are not fully understood, however. The purpose of present study was to test our hypothesis that dynamic arterial baroreflex-mediated cardiovascular responses ...

It is presently unknown whether there are sex differences in the magnitude of blood pressure (BP) responses to baroreceptor perturbation or if the relative contribution of cardiac output (CO) and total vascular conductance (TVC) to baroreflex-mediated changes in BP differs in young women and men. Since sympathetic vasoconstrictor tone is attenuated in women, we hypothesized that carotid baroref...

PURPOSE We aim to evaluate the effects of multileaf collimator (MLC) leaf width (5 mm vs. 2.5 mm) on the radiosurgery planning for the treatment of spine lesions according to the modulated techniques (intensity-modulated radiotherapy [IMRT] vs. volumetric-modulated arc therapy [VMAT]) and the complexity of the target shape. METHODS For this study, artificial spinal lesions were contoured and ...

Temporal graphs naturally model whose underlying topology changes over time. Recently, the problems Vertex Cover (or TVC) and Sliding-Window Delta-TVC for time-windows of a fixed-length Delta) have been established as natural extensions classic problem on static with connections to areas such surveillance in sensor networks. In this paper we initiate systematic study complexity TVC sparse graph...
