Abstract. The researches on a vapor cycle system start late in China. The vapor cycle cooling system is not a mature technolog. With the aid of advanced refrigeration technology at home and abroad, this paper focuses on research and development of the vapor cycle cooling system of the helicopter. Based on the design parameters of the vapor cycle cooling system, this paper carries out the match design, determines the operation condition and thermodynamic cycle pressure-enthalpy chart, conducts thermodynamic calculation, and obtains the main performance parameters and the required refrigerating capacity, which provides a basis for the match design in the actual system.

This paper describes our approaches, experiments, and results. As the approach for each task is quite different, the paper contains a section for each of the tasks. The following section describes our experiments in adaptive filtering, Section 3 describes named-page finding, and section 4 discusses the Novelty track

Objective To investigate the epidemic characteristics of human cutaneous anthrax (CA) in China, detect the spatiotemporal clusters at the county level for preemptive public health interven-tions, and evaluate the differences in the epidemiological characteristics within and outside clusters. Methods CA cases reported during 2005–2012 from the national surveillance system were evaluated at the county level using space-time scan statistic. Comparative analysis of the epidemic characteristics within and outside identified clusters was performed using using the χ2 test or Kruskal-Wallis test. Results The group of 30–39 years had the highest incidence of CA, and the fatality rate increased with age, with persons70 years showing a fatality rate of 4.04%. Seasonality analysis showed that most of CA cases occurred between May/June and September/October of

The goal of this study was to demonstrate high-resolution an-atomical, blood oxygenation level-dependent, and blood flow MRI on large nonhuman primate retinas using a 3-Tesla clini-cal scanner as a first step toward translation. Baboon was chosen because of its evolutionary similarity to human. Anes-thetized preparation, free of eye-movement artifacts, was used to evaluate clinical scanner hardware feasibility and optimize multimodal protocols for retinal MRI. Anatomical MRI (0.1 3 0.2 3 2.0 mm3) before contrast-agent injection detected three alternating bright–dark–bright layers. The hyperintense inner strip nearest to the vitreous was enhanced by an intravascular contrast agent, which likely included the ganglion and bipolar cell layer and the embedded retinal ves-sels. The hypointense middle strip showed no contrast enhancement, which likely included the avascular outer unclear layer and photoreceptor segments. The hyperintense outer strip showed contrast enhancement, which likely corre-sponded to the choroid vascular layer. In the posterior retina, the total thickness including the choroid was 617 6 101 mm (6 standard deviation, n 5 7). Blood oxygenation level-de-pendent functional MRI (0.3 3 0.6 3 2.0 mm3) of oxygen inha-lation relative to air increased the signals by 6.5 6 1.4%. Basal blood flow (2 3 2 3 2 mm3) was 83 6 30 mL/100 g/min (air), and hypercapnia increased blood flow by 25 6 9 % (P < 0.05). This study demonstrates multimodal MRI to image anat-omy, physiology, and function on large nonhuman primate retinas using a clinical scanner, offering encouraging data to explore human applications.

Abstract. The purpose of this paper is to develop point-line displace-ments of a line, given by Yi Zhang and Kwun-Lon Ting [6] in R3, in R31. Firstly, we define dual split quaternions and give some algebraic properties of them. Also we discuss the screw motion and some geometrical applica-tions
