Spatial and temporal properties of head movement are encoded by vestibular hair cells in the inner ear. One of the most striking features of these receptors is the orderly structural variation in their mechanoreceptive hair bundles, but the functional significance of this diversity is poorly understood. We tested the hypothesis that hair bundle structure is a significant contributor to hair bun...
PURPOSE In its most severe form, retinopathy of prematurity (ROP) is located in posterior retina and affects the smallest, most premature infants. We hypothesize that, depending on whether vasculogenesis (de novo formation of new vessels by transformation of vascular precursor cells (VPCs)) or angiogenesis (budding from existing vessels) is perturbed, it results in significant differences in cl...
BACKGROUND Percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) is superior to fibrinolysis when performed in a timely manner in high-volume centers. Recent European trials suggest that transfer for PCI also may be superior to fibrinolysis and increase access to PCI. In the United States, transfer times are consistently long; therefore, many believe a transfer...
Probability distributions of human displacements have been fit with exponentially truncated Lévy flights or fat tailed Pareto inverse power law probability distributions. Thus, people usually stay within a given location (for example, the city of residence), but with a non-vanishing frequency they visit nearby or far locations too. Herein, we show that an important empirical distribution of hum...
The harvesting of processing tomatoes is fully mechanised and it is well known that during harvest, fruits are subjected to mechanical stress causing physical injuries, including skin punctures, pulp and cell rupture. Some wireless sensors have been used for research during recent years with the main purpose of reducing the quality loss of tomato fruits by diminishing the number and intensity o...
S U M M A R Y Mechanisms leading to the initiation and early-stage development of continental rifts remain enigmatic, in spite of numerous studies. Among the various rifting models, which were developed mostly based on studies of mature rifts, far-field stresses originating from plate interactions (passive rifting) and nearby active mantle upwelling (active rifting) are commonly used to explain...
Risk analysis and an alternative protocol for reduction of screening for retinopathy of prematurity.
PURPOSE To determine whether a multivariate risk model can select infants with low-risk eyes for an alternative protocol that reduces retinopathy of prematurity (ROP) screening without loss of effectiveness. METHODS This was a retrospective, nonrandomized, comparative study. We assigned 712 eyes of 357 premature infants of 401-1,250 g birth weights as high or low risk for prethreshold or thre...
PURPOSE To establish the relationship between a subjective (session rating of perceived exertion [RPE]) and 2 objective (training impulse [TRIMP]) and summatedheart- rate-zone (SHRZ) methods of quantifying training load and explain characteristics of the variance not accounted for in these relationships. METHODS Thirty-three participants trained ad libitum for 2 wk, and their heart rate (HR) ...
OBJECTIVE To evaluate the aesthetic results in our initial group of patients treated with a combination of a midface-lift and fat transfer compared with a randomly selected group of patients who underwent a midface-lift without concurrent fat transfer by one of us. METHODS The setting was a private, ambulatory, surgical center. The design was a comparative study between patients who did or di...
تشکیلات پابده برای اولین بار در برش تنگ زنجیران (زاگرس چین خورده، فارس داخلی) به منظور معرفی بیوزون ها و گسترش زمانی آنها، بر اساس جدیدترین بیوزوناسیون ارائه شده در حوضه تتیس مطالعه شده است. در این مطالعه 15 بیوزون گزارش شده است (1b- S.triloculinoides Subzone, 1c- G.compressa / P.inconstans Subzone, 2- P.uncinata Zone,3a- M.angulata Subzone,3b- G.pseudomenardii / M.angulata Subzone, 4- G.ps...
