NASA is developing the Climate Absolute Radiance and Refractivity observatory (CLARREo) mission to provide accurate measurements to substantially improve understanding of climate change. CLARREo will include a Reflected Solar (RS) Suite, an Infrared (IR) Suite, and a Global Navigation Satellite System-Radio occultation (GNSS-Ro). The IR Suite consists of a Fourier Transform Spectrometer (FTS) covering 5 to 50 micrometers (2000-200 cm-1 wavenumbers) and on-orbit calibration and verification systems. The IR instrument will use a cavity blackbody view and a deep space view for on-orbit calibration. The calibration blackbody and the verification system blackbody will both have Phase Change Cells (PCCs) to accurately provide a SI reference to absolute temperature. one of the most critical parts of obtaining accurate CLARREo IR scene measurements relies on knowing the spectral radiance output from the blackbody calibration source. The blackbody spectral radiance must be known with a low uncertainty, and the magnitude of the uncertainty itself must be reliably quantified. This study focuses on determining which parameters in the spectral radiance equation of the calibration blackbody are critical to the blackbody accuracy. Fourteen parameters are identified and explored. Design of Experiments (DoE) is applied to systematically set up an experiment (i.e., parameter settings and number of runs) to explore the effects of these 14 parameters. The experiment is done by computer simulation to estimate uncertainty of the calibration blackbody spectral radiance. Within the explored ranges, only 4 out of 14 parameters were discovered to be critical to the total uncertainty in blackbody radiance, and should be designed, manufactured, and/or controlled carefully. The uncertainties obtained by computer simulation are also compared to those obtained using the “Law of Propagation of Uncertainty”. The two methods produce statistically different uncertainties. Nevertheless, the difference

丰富的奥运历史中既有鼓舞人心的成就,却也不乏富有争议的时刻,如下是十三个里程碑事件,它们对今天的世界和奥运盛会都产生了最为深远的影响。1.1900年巴黎:第一位女运动员1900年巴黎奥运会之前,女性是禁止参加比赛的,在那届奥运会上,女性运动员参加了网球和高尔夫球两个项目,这为女运动员在以后的奥运会中争得一席之地。2012年伦敦奥运会又为男女平等树立了一块新的里程碑。此届女性首次参加了拳击项目比赛,而且首次所有国家代表团均有女运动员参赛。

　　Heart Failure (HF) is a major source of morbidity and mortality worldwide. In the United States, five million people carry this diagnosis. It accounts for in excess of one million hospitalizations and costs approximately $30 billion to *** elderly population is particularly affected since more than 80% of those hospitalized for HF are over age 65 *** the development of evidence-based therapy and guidelines in the management of chronic HF for use by physicians and other health care providers, the mortality remains high.……

用线性波传播模型再现视非线性地震响应

世界地震译丛 2000年第6期31卷 77-84页

作者： D.R.H.o'connell 柯善明张玲辽宁省地震局

在地震工程中,地震荷载的预测需了解沉积层地面运动的放大作用,它定义为沉积层场地与岩石场地地面运动大小的比值。在1994年北岭地震中,观测到的沉积层场地余震的(震级为3～4)弱地面运动放大作用是主震(震级为6.7)放大作用的2倍。这种... 详细信息

在地震工程中,地震荷载的预测需了解沉积层地面运动的放大作用,它定义为沉积层场地与岩石场地地面运动大小的比值。在1994年北岭地震中,观测到的沉积层场地余震的(震级为3～4)弱地面运动放大作用是主震(震级为6.7)放大作用的2倍。这种现象的一种解释是沉积层振幅的放大(非线性)作用。然而,利用经验脉冲响应进行的地震模拟和用弱非均匀性、随机三维地壳速度弹性有限差分法的计算表明,线性波传播模型可以解释所观测到的(表现为非线性)沉积层场地的这种地震响应。随机三维速度变化同样可以再现观测到的峰值地面运动的对数-正态频散。确定性的波传播模型不足以定量地研究近源地面运动的定标律和频散。

Virologica Sinica 2015年第5期30卷 344-353页

作者： Erin Allmann Updyke Zi Wang Si Sun Christina connell Marek Kirs Mayee Wong Yuanan Lu Department of Public Health Sciences University of Hawai‘i at Mānoa Water Resources Research Center University of Hawai‘i at Mānoa

Recreational waters contaminated with human fecal pollution are a public health concern, and ensuring the safety of recreational waters for public use is a priority of both the Environmental Protection Agency(EPA) and the Centers for Disease Control and Prevention(CDC). Current recreational water standards rely on fecal indicator bacteria(FIB) levels as indicators of human disease risk. However present evidence indicates that levels of FIB do not always correspond to the presence of other potentially harmful organisms, such as viruses. Thus, enteric viruses are currently tested as water quality indicators, but have yet to be successfully implemented in routine monitoring of water quality. This study utilized enteric viruses as possible alternative indicators of water quality to examine 18 different fresh and offshore recreational waters on o‘ahu, Hawai‘i, by using newly established laboratory techniques including highly optimized PCR, real time PCR, and viral infectivity assays. All sample sites were detected positive for human enteric viruses by PCR including enterovirus, norovirus genogroups I and II, and male specific FRNA coliphage. A six time-point seasonal study of enteric virus presence indicated significant variation in virus detection between the rainy and dry seasons. Quantitative PCR detected the presence of norovirus genogroup II at levels at which disease risk may occur, and there was no correlation found between enteric virus presence and FIB counts. Under the present laboratory conditions, no infectious viruses were detected from the samples PCR-positive for enteric viruses. These data emphasize both the need for additional indicators for improved monitoring of water quality, and the feasibility of using enteric viruses as these indicators.
