This paper outlines a diagnostic approach to quantify the maintainability of a Commercial off-the-Shelf （COTS）-based system by analyzing the complexity of the deployment of the system components. Interpretive Structural Modeling （ISM） is used to demonstrate how ISM supports in identifying and understanding interdependencies among COTS components and how they affect the complexity of the maintenance of the COTS Based System （CBS）. Through ISM analysis we have determined which components in the CBS contribute most significantly to the complexity of the system. With the ISM, architects, system integrators, and system maintainers can isolate the COTS products that cause the most complexity, and therefore cause the most effort to maintain, and take precautions to only change those products when necessary or during major maintenance efforts. The analysis also clearly shows the components that can be easily replaced or upgraded with very little impact on the rest of the system.

We present multi-wavelength imagery of the merger remnant galaxy NGC 1316 with an objective to study the dust content and its association with the other phases of the interstellar medium. Color-index maps as well as extinction maps derived for this galaxy reveal an intricate and complex dust morphology in NGC 1316, i.e. there is a prominent lane in the inner part, while at about 6-7 kpc it apparently takes the form of an arc-like pattern extending along the northeast direction. In addition to this, several other dust clumps and knots are also evident in this galaxy. The dust emission mapped using Spitzer data at 8 μm indicates even more complex morphological structures of the dust in NGC 1316. The extinction curve derived over the optical to near-IR bands closely follows the standard Galactic curve, suggesting similar properties of the dust grains. The dust content of NGC 1316, estimated from optical extinction, is ,- 2.13 × 10^5 M⊙. This is a lower limit compared to that estimated using the IRAS flux densities of ,-5.17× 10^6 M⊙ and the flux densities at 24, 70 and 160 p.m from MIPS ,-3.2× 10^7 M⊙. High resolution Chandra observations of this merger remnant system have provided an unprecedented view of the complex nature exhibited by the distribution of hot gas in NGC 1316, which closely matches the morphology of ionized gas and to some extent also the dust. X-ray color-color plots for the resolved sources within the optical d25 extent of NGC 1316 have enabled us to separate them into different classes.

随着科学与技术的发展，临床检验近年出现了许多新的检验项目，尤其是利用免疫学原理对某些浓度很低的特殊蛋白的检测，但这些检测的结果可以是方法特异的，一种方法结果可能无法与其他方法结果相比较。为实现标准化或一致化，不同免疫分析的方法设计需具有可比性，校准物需溯源至同一参考物质。新的欧盟法规要求体外诊断产品的校准物和控制物的定值需具有溯源性，此要求适用所有体外诊断产品，对全球制造商和临床实验室产生影响。溯源原理基于EN ISO 17511，方法间结果的可比性有赖于合理设计的参考系统。此参考系统包括下列基本要素：足够明确的分析物定义，参考测量程序，适当的一级和次级参考物质，经过认可的参考实验室网络，临床溯源性相关信息，以及测量不确定度表述等。溯源性通过不间断的校准链（溯源链）实现，后者由交替出现的测量程序和校准物质组成。SI溯源链始于分析物的SI单位定义，随后通过一级参考测量程序和一级参考物质传递SI单位。量值的准确性或正确性源于一级参考测量程序和一级参考物质，但由于一级参考物质价格昂贵，一级参考测量程序无法在常规检测中应用，尚需中间的校准物和方法将准确性传递至产品校准物，最终至患者样品。每一次传递都会增加误差或不确定度，因此溯源链的传递步骤越少越好。正确的传递链要求每一测量程序的检测特异性和每一校准品的互通性，达不到这些要求会使溯源链中断。制造商还需确定校准品定值的不确定度并将这一信息提供给用户，在计量学上不确定度与定值同样重要。临床实验室位于溯源链的终端，结果的溯源性有赖于制造商所使用和描述的参考测量程序和参考物质。建立校准物的溯源性和改进检验结果的可比性需要标准化计划，这意味着使检测结果尽可能接近上一级参考测量程序得到的真值。采用较低级别的公认方法为特定的参考物质定值时，上述过程表述为“一致化”，而不是“标准化”，因为一致的结果不一定是真值。为整理和公布检验医学现有较高级别参考物质、参考测量程序和参考实验室，国际计量局（BIPM）、国际临床化学联合会（IFCC）和国际实验室认可协会（ILAC）成立检验医学溯源联合委员会（简称JCTLM）。JCLTM的主要任务是通过实施参考系统，建立检验结果溯源性，改进其可比性，从而提高医疗卫生质量并降低费用。JCTLM设立工作框架，按照国际标准（ISO 17511，15193，15194）建立参考物质和参考测量程序认定步骤。工作任务被很快确立并付诸实施，包括建立参考物质和参考测量程序列表，建立参考实验室网络，建立新的参考物质和参考测量程序的审批程序，以及合作研发新的参考物质和参考测量程序。

A multiwavelength study of a nearby dust lane early-type galaxy IC 5063 is presented. The objectives are to investigate dust extinction properties and the association of interstellar dust with other phases of ISM. The color-index maps as well as the extinction maps derived from the analysis of deep CCd observations in optical passbands revealed a prominent dust lane along its optical major axis in the inner region. In addition, two more fainter and extended dust patterns are apparent in the color index map as well as extinction maps. These features are also evident in the smooth model subtracted residual maps. The extinction curve derived for this galaxy revealed that dust grains in it are identical to the canonical grains in the Milky Way with the dust grains little larger than the canonical grains. The total extinction measured in the V band extinction map enabled us to quantify the dust content of this galaxy to be equal to , an order of magnitude shorter than that estimated using the IRAS flux densities at 60 and 100 μm. A Multiphase ISM study revealed a surprising similarity in the morphologies of the Hα emitting ionized gas distribution and X-ray emitting gas. Systematic analysis of high resolution X-ray observations using Chandra telescope enabled us to detect 18 discrete X-ray sources within optical d25 region of IC 5063, out of which 17 sources were separated out as the low mass X-ray binaries and one as the high mass X-ray binary source in the X-ray color-color plot.

The Great Plains region of the United States is susceptible to drought of all kinds including meteorological/climatological, agricultural, hydrological, and socioeconomic. drought conditions in the region span varying spatial and temporal scales and the causes include: 1) certain synoptic conditions that favor drought such as mid-tropospheric ridging over the drought-affected area and a weak low-level jet;2) sea surface temperature anomalies and associated teleconnections;3) land-atmosphere coupling;and 4) anthropogenic effects. While drought can span as few as a couple of months, the most severe droughts can occur at the decadal scale such as the 1930s dust Bowl, the worst drought in recent history from a societal standpoint. Such droughts in the Great Plains have widespread impacts on agriculture, water resources, human health, and the economy.

Principles of dimensional analysis are applied in a new interpretation of penetration of ceramic targets subjected to hypervelocity impact. The analysis results in a power series representation – in terms of inverse velocity – of normalized depth of penetration that reduces to the hydrodynamic solution at high impact velocities. Specifically considered are test data from four literature sources involving penetration of confined thick ceramic targets by tungsten long rod projectiles. The ceramics are Ad-995 alumina, aluminum nitride, silicon carbide, and boron *** data can be accurately represented by the linear form of the power series, whereby the same value of a single fitting parameter applies remarkably well for all four ceramics. Comparison of the present model with others in the literature(e.g., tate's theory) demonstrates a target resistance stress that depends on impact velocity, linearly in the limiting case. Comparison of the present analysis with recent research involving penetration of thin ceramic tiles at lower typical impact velocities confirms the importance of target properties related to fracture and shear strength at the Hugoniot Elastic Limit(HEL) only in the latter. In contrast, in the former(i.e., hypervelocity and thick target) experiments, the current analysis demonstrates dominant dependence of penetration depth only by target mass density. Such comparisons suggest transitions from microstructure-controlled to density-controlled penetration resistance with increasing impact velocity and ceramic target *** and hosting by Elsevier B.V. on behalf of China Ordnance Society.

Opsoclonus-myoclonus syndrome (OMS) is an autoimmune disorder with serious neurodevelopmental morbidity and limited treatment options. We treated a toddler with moderately severe OMS with rituximab, a monoclonal anti-B cell antibody. The patient’s clinical response was documented on videotape and scored with the OMS Evaluation Scale. Cerebrospinal fluid lymphocyte subsets were evaluated by flow-cytometric immunophenotyping, with a comprehensive panel of monoclonal antibodies. Eradication of cerebrospinal fluid B cells, which previously were expanded, was associated with dramatic clinical improvement. There also were secondary changes in other lymphocyte subsets that might be relevant to the clinical response and lack of serious infections. In addition to clarifying the immune response to B-cell depletion, these data reveal a promising new therapy for OMS that warrants a phase I clinical trial.

Objectives: Parents of children with opsoclonus-myoclonus syndrome (OMS) frequently describe poor sleep and rage attacks. We hypothesized that these manifestations are related and could result from underlying monoaminergic dysfunction. Study design: We clinically characterized the sleep and behavioral characteristics of 51 young children with OMS; 19 of those with the most disruptive sleep patterns were treated with trazodone, a soporific serotonergic agent. Results: Sleep disturbances, including prolonged sleep latency, fragmented sleep, reduced quantity of sleep, snoring, and nonrestorative sleep, were reported in 32 children, and frequent rage attacks were reported in 25. In 59% of the poor sleepers, parents felt that the problem was severe enough to warrant treatment. Children sleeping d a higher rage frequency than those who slept more. Of the children who required trazodone, 84% were receiving corticosteroids or adrenocorticotropic hormone (corticotrophin), compared with 37% in the subgroup with normal sleep. Trazodone (3.0 ± 0.4 mg/kg/day) improved sleep and behavior in 95% of the children, significantly increasing total sleep time by 72% , decreasing the number of awakenings by 76% , and reducing rage attacks by 33% . Conclusions: Children with OMS exhibited multiple types of sleep disturbances, which contributed to rage attacks. Trazodone was effective in improving sleep and decreasing rage attacks and was well tolerated, even in toddlers.
