Human-Centric Composite-Quality Modeling and Assessment for Virtual Desktop Clouds

ZTE Communications 2013年第1期11卷 27-36页

作者： Yingxiao Xu Prasad Calyam David Welling Saravanan Mohan Alex Berryman Rajiv ramnath Fudan University University of Missouri MO 65201USA Ohio Supercomputer Center/OARnet OH 43212USA The Ohio State University OH 43210USA

There are several motivations, such as mobility, cost, and secu- rity, that are behind the trend of traditional desktop users transi- tioning to thin-client-based virtual desktop clouds （VDCs）. Such a trend has led to the rising importance of human-centric performance modeling and assessment within user communities that are increasingly making use of desktop virtualization. In this paper, we present a novel reference architecture and its eas- ily deployable implementation for modeling and assessing objec- tive user quality of experience （QoE） in VDCs. This architec- ture eliminates the need for expensive, time-consuming subjec- tive testing and incorporates finite-state machine representa- tions for user workload generation. It also incorporates slow-mo- tion benchmarking with deep-packet inspection of application task performance affected by QoS variations. In this way, a ＂composite-quality＂ metric model of user QoE can be derived. We show how this metric can be customized to a particular user group profile with different application sets and can be used to a） identify dominant performance indicators and troubleshoot bottlenecks and b） obtain both absolute and relative objective user QoE measurements needed for pertinent selection of thin-client encoding configurations in VDCs. We validate our composite-quality modeling and assessment methodology by us- ing subjective and objective user QoE measurements in a re- al-world VDC called VDPilot, which uses RDP and PCoIP thin-client protocols. In our case study, actual users are pres- ent in virtual classrooms within a regional federated university system.

甜菜单胞锈菌 Uromyces belae *** kickx 引起的甜菜锈病是许多国家的一种造成产量严重损失的种传病害,以污染和侵染种子的冬孢子为初侵染源引入和传播于新的地区。目前,在印度还没有发现该病。由于这种病的严重性,曾发现几批感染该菌的进口甜菜种子都不得不退回和毁掉。1985年期间,我们收到英国剑桥植物育种所约1kg剥皮甜菜种子,当进行检疫检验时,发现种样感染有甜菜单胞锈菌的夏孢子和冬孢子及甜菜蛇眼病病菌茎点霉 Phoma betae

Effects of selenomethionine on acute toxicities from concurrent chemoradiation for inoperable stage Ⅲ nonsmall cell lung cancer

引用

World Journal of Clinical Oncology 2015年第5期6卷 156-165页

AIM: To prospectively determine the safety and tolerability of oral L-selenomethionine(SLM) with concurrent chemoradiation(CCRT) for Stage Ⅲ non-small cell lung cancer(NSCLC) and estimate if the incidence and/or severity of adverse events could be reduced by its ***: Sixteen patients with stage Ⅲ NSCLC were accrued to this single arm, phase Ⅱ study. CCRT consisted of radiation given at 2 Gy per fraction for 30-33 fractions, 5 d per week with concurrent weekly Ⅳ paclitaxel 50 mg/m2 followed by carboplatin dosed at an area under the time-concentration curve of 2. SLM was dosed in a loading phase at 4800 μg twice daily for one week prior to CCRT followed by once daily dosing during treatment. RESULTS: No selenium-related toxicity was observed. Analysis revealed grade 3 or higher esophagitis in 3 of 16 patients(19%), pneumonitis in 0, leukopenia in 2(12.5%), and anemia in 1(6%); the latter two were significantly reduced when compared to the protocolstated expected rate of 35%(P = 0.045 for leukopenia, and P < 0.01 for anemia). Median overall survival was 14.9 mo and median failure-free survival was 9 mo(95%CI: 3.3-21.5).CONCLUSION: There may be some protective benefit of selenium in the setting of CCRT for inoperable NSCLC. The data suggests decreased rates of myelosuppression when compared to similarly-treated historical and contemporary controls. Further evaluation of selenium in this setting may be warranted.

The MCCI （Millon College Counseling Inventory） in an Ethnically Diverse Student Population

引用

Psychology Research 2011年第2期1卷 73-82页

作者： Liane Dornheim R. ramnath C. Gomez, H von Harscher A. Pellegrini Florida International University Florida USA

This study examined psychometric properties of the MCCI (Millon College Counseling Inventory) (T. Millon, Strack, C. Millon, & Grossman, 2006), as applied to students from ethnically and culturally diverse backgrounds. The sample (N = 209, Mean age = 23.81, 74% identified as ethnic minority) was derived from students presented for counseling services in a large southeastern state university. Cronbach alpha analyses across all scales were robust; the overall mean alpha coefficient was 0.73, with the vast majority demonstrating alpha coefficients of 0.70 or higher. An analysis of principal components was conducted, as well to examine the instrument"s underlying factor structure. This yielded a seven-component solution explaining 70.15% of the total variance. Communalities ranged from 0.403 to 0.876 and the rotated component pattern demonstrated simple structure. In summary, when applied to an ethnically diverse sample, the MCCI yielded a performance reflective of the original standardization sample, suggesting its appropriateness for use with an ethnically diverse student body.
