Damping in a Squeezed Bath and Its Time Evolution through the Complete Class of Gaussian Quasi-Distributions

Chinese Physics Letters 2014年第7期31卷 20-23页

By virtue of the thermo-entangled states representation of the density operator and using the dissipative interaction picture, we solve the master equation of a driven damped harmonic oscillator in a squeezed bath. We show that the essential part of the dynamics can be expressed by the convolution of the initial Wigner function with a special kind of normalized Gaussian in the phase space and relate the dynamics with the change of Gaussian ordering of the density operator.

Spray Pyrolysis Deposition of ZnO Thin Films from Zinc Chloride Precursor Solution at Different Substrate Temperatures

引用

Acta Metallurgica Sinica(English Letters) 2015年第1期28卷 110-114页

作者： fahimeh Zahedi reza Sabet Dariani seyed mohammad Rozati Department of Physics Alzahra University Department of Physics University of Guilan

ZnO films were prepared at different substrate temperatures through spraying pyrolysis deposition of zinc chloride precursor onto glass substrate. Substrate temperature affects surface morphology of films and therefore their optical and electrical properties. All films are polycrystalline with Wurtzite crystal structure and preferentially grow along c-axis direction. Formation of ZnO rods start at about 500 °C. The diameter and length of rods deposited at 500 °C are350–500 and 550–700 nm, respectively. By increasing substrate temperature, film becomes more coverage and diameter of the rods reduces to 250–300 nm but their length increases to 1,000–1,200 nm, respectively. Optical transmission in visible region decreases with increasing substrate temperature. An ultraviolet emission and two visible emissions at 2.82 and2.37 eV are observed for photoluminescence spectra at room temperature. The resistivity of ZnO films increases with increasing substrate temperature due to surface morphology.

我们报道罕见的脉络膜黑色素细胞瘤1例,以视网膜母细胞瘤之诊断行眼球内容物剜除术。患儿14mo,以左眼外斜视约10mo主诉就诊。眼科检查及影像学检查显示视网膜脱离并钙化病灶。患儿诊断为视网膜母细胞瘤,患眼行眼球内容物剜除术。组织病理学检查显示肿瘤细胞体积大,多面体型,核小,胞浆含大量黑色素颗粒,提示脉络膜及睫状体黑素细胞瘤之诊断。以往有脉络膜及睫状体黑色素细胞瘤表现类似与恶性黑素瘤的报道,但是,黑色素细胞瘤表现为钙化病灶及视网膜脱离,被误诊为视网膜母细胞瘤,此病例罕见,以往未见报道。

Purpose:Injuries are one of the leading causes of death and lead to a high social and financial *** patterns can vary significantly among different age groups and body *** study aimed to evaluate the relationship between mechanism of injury,patient comorbidities and severity of ***:The study included trauma patients from July 2016 to June 2018,who were admitted to Sina Hospital,Tehran,*** inclusion criteria were all injured patients who had at least one of the following:hospital length of stay more than 24 h,death in hospital,and transfer from the intensive care unit of another *** collection was performed using the National Trauma Registry of Iran minimum ***:The most common injury mechanism was road traffic injuries(49.0%),followed by falls(25.5%).The mean age of those who fell was significantly higher in comparison with other mechanisms(p<0.001).Severe extremity injuries occurred more often in the fall group than in the vehicle collision group(69.0%vs.43.5%,p<0.001).Moreover,cases of severe multiple trauma were higher amongst vehicle collisions than injuries caused by falls(27.8%vs.12.9%,p=0.003).Conclusion:Comparing falls with motor vehicle collisions,patients who fell were older and sustained more extremity *** injured by motor vehicle collision were more likely to have sustained multiple trauma than those presenting with *** of the relationship between mechanisms and consequences of injuries may lead to more effective interventions.
