The ALARA [Analytic and Laplacian Adaptive Radioactivity Analysis][1] activation code, previously validated for its accuracy and precision [2], has now been validated for arbitrary irradiation schedules. Based on the International Atomic Energy Agency [IAEA] Fusion Evaluated Nuclear Data Library [FENDL] Calculational Activation Benchmark[3], eight irradiation schedules were designed, each conse...

This study investigates the radiation dose and image quality of patients not receiving β-blockers for cardiac CT angiography (CCTA) with or without the optimization of electrocardiographic (ECG) pulsing window. The differences in patient characteristics are also characterized.Normal-weight and obese patients (n = 154) with heart rates between 65 and 80 beats per minutes (bpm) during the prospec...

a study was conducted to standardize production and postharvest handling of lily (lilium longifolium l. cv. mero star). in production trial, three plant densities viz.10, 20 and 30 cm between plants in 60 cm spaced rows and two planting depths viz.7.5 and 15 cm were compared. increased plant growth, yield and quality was recorded when plants were grown at a close spacing of 10 cm with 15 cm pla...

Multiple pulsing occurs in most ultrashort-pulse laser systems when pumped at excessively high powers, and small fluctuations in pump power in certain regimes can cause unusual variations in the temporal separations of sub-pulses. Unfortunately, the ability of modern intensity-and-phase pulse measurement techniques to measure such unstable multi-pulsing has not been studied. Here we report calc...

The threshold pressure of single baroreceptor units is decreased after compared with before exposure to pulsatile pressure according to previous studies in our laboratory. The purpose of the present study is to characterize the determinants of sensitization of arterial baroreceptors by pulsatile pressure. Carotid sinus nerve activity was recorded in dogs anesthetized with chloralose. Two indexe...

Triggered pulsing in a multi-quantum well structure which shows s-type negative differential resistance (NDR) was investigated. First return maps of the inter-pulse time intervals (IPTI) show an interesting grouping pattern at slower pulse rates. Oscillations in the pulsing threshold level of the MQW device cause the grouping behavior. This pattern of IPTIs is similar to that of thermoreceptors...

While many organisms filter feed and exchange heat or nutrients in flow, few benthic organisms also actively pulse to enhance feeding and exchange. One example is the pulsing soft coral (Heteroxenia fuscescens). Pulsing corals live in colonies, where each polyp actively pulses through contraction and relaxation of their tentacles. The pulses are typically out of phase and without a clear patter...
