Full-aperture backscatter diagnostics and applications at the Texas Petawatt Laser facility

In this paper, we present the development and application of a full-aperture baekscatter diagnostics system at the Texas Petawatt Laser （TPW） facility. The diagnostic system includes three independent diagnostic stations. With this system, we obtained TPW on-shot focus properties, and high-harmonic spectral emission flOln solid foils （e.g., cu and Al） and their Si substrate in an experiment to study laser hole boring, which show the hole-boring mechanism at relativistic intensities. The measured on-target full-power focal spots from ultrathin film targets help determine the optimum target thickness at certain laser contrast parameters for particle acceleration and neutron generation experiment, which is also a relative measurement of shot-to- shot intensity fluctuations.

背景在初级保健中,越来越多采用定量粪便免疫化学试验（FIT）排除高危症状患者结直肠癌（cRc）.目的本研究旨在探讨全科医生对紧急2周等待（2WW）转诊和采用FIT的态度和意愿.设计与场所涉及英国1024位全科医生的一项在线横断面调查.方法采用Logistic回归模型探讨全科医生采用FIT而非2WW转诊的可能性,并使用优势比（OR）和95%可信区间（95%cI）.结果略超过1/3的全科医生（n=365）倾向于采用FIT来排除2WW转诊的需要.以下全科医生更愿意采用FIT：年龄在36-45岁〔OR=1.59,95%cI（1.04,2.44）〕;年龄在46-55岁〔OR=1.99,95%cI（1.14,3.47）〕;认为FIT高度准确〔OR=1.63,95%cI（1.16,2.29）〕;认为与结肠镜检查相比,FIT对患者更有好处〔OR=2.02,95%cI（1.46,2.79）〕;对FIT的好处非常自信〔OR=2.14,95%cI（1.46,3.16）〕.如果全科医生在过去1年中有超过10次紧急2WW转诊〔OR=0.62,95%cI（0.40,0.94）〕,那么其更不愿意采用FIT,并认为需要更长时间的会诊〔OR=0.61,95%cI（0.44,0.83）〕.结论目前在初级保健中将FIT作为排除cRc的接受度较低,不到一半的全科医生认为其比结肠镜检查准确.未来任何建议在高危症状患者中采用FIT而非紧急2WW转诊排除cRc的指导方针均需要强化支持教育延伸,以提高全科医生对FIT准确性及其应用的信心.

Background/Purpose: Lipoblastoma/lipoblastomatosis, a rare benign pediatric tumor composed of embryonic fat, most often presents as a rapidly growing mass in children younger than 3 years. This benign tumor locally recurs up to 25%of the *** retrospective review was done to emphasize problems with diagnosis, management, and the approach to follow-up ***: Sixteen cases of pathologically proven lipoblastoma presenting to a single institution over a 16-year period (1988-2004) were reviewed retrospectively for clinical features and outcome. Results: There were 11 males and 5 females ranging in age from 18 days to 12.75 years. Preoperative diagnoses were accurate in only 3 cases. Two lesions recurred locally over a period of 10 months and 5 years. One lesion presented with local infiltration. Six lesions were right-sided, 5 were left-sided,and 5 were midline. conclusions: It is important to consider lipoblastoma in the diagnosis of a rapidly enlarging fatty mass in children. complete resection is the only definitive treatment and should not be delayed when impingement on surrounding structures is imminent. There is a tendency for these lesions to recur despite presumed complete excision. Therefore, followup for a minimum of 5 years is recommended.

Feedback control for Ecosystem Management:The case of Wolf-Elk-Hunting Dynamics in the US Mountain West

引用

Journal of Mountain Science 2014年第4期11卷 850-865页

作者： Kevin MAcKSAMIE Jeffrey wagner Juan c.cOcKBURN Black River Systems company Inc. 162 Genesee Street Utica New York 13507 USA Department of Economics Rochester Institute of Technology 92 Lomb Memorial Drive Rochester NY 14623 USA Department of computer Engineering Rochester Institute of Technology 83 Lomb Memorial Drive Rochester NY 14623USA

The purpose of this paper is to explore the promise of utilizing some relatively new feedback control techniques in ecosystem management. First, we set forth a basic ecological-economic model of a predator-prey-hunting system in which both the predator and prey have use(flow) and non-use(stock) value and when the predator can inflict transboundary damages. We then use new data from the US Mountain West to show how a particular feedback approach—linear parameter-varying(LPV) control—can be utilized in this context. Our LPV model is able to quantify the cost of managing disturbances that inevitably arise as a manager tries to keep the actual path of the system "close" to its optimum. The results suggest management strategies in mountain ecosystems that feature large, mammalian carnivores.
