2The distribution and evolution of fluid pressure and its influence on natural gas accumulation in the Upper Paleozoic of Shenmu-Yulin area, Ordos Basin显示文摘On the basis of measuring the pressure distribution and analyzing its origin in the Carboniferous and Permian of Shenmu-Yulin area, the evolution history of ancient pressure is restored mainly by means of the basin numerical simulation technique, in which the paleo-pressure has been constrained by the compaction restoration and the examination of fluid inclusion temperature and pressure. Then the development and evolution history of abnormal pressure and its effect on gas migration and accumulation are investigated. Studies show that the pressure in southeastern and northwestern parts of studied area is near to hydrostatic pressure, whereas in the remainder vast area the pressure is lower than the hydrostatic pressure, which is caused by difficulty to measure pressure accurately in tight reservoir bed, the calculating error caused by in-coordinate between topography relief and surface of water potential, pressure lessening due to formation arising and erosion. There are geological factors beneficial to forming abnormal high pressure in the Upper Palaeozoic. On the distraction of measured pressure, paleo-pressure data from compaction restoration and fluid inclusion temperature and pressure exa- mining, the evolution history of ancient pressure is restored by the basin numerical simulation technique. It is pointed out that there are at least two high peaks of overpressure in which the highest value of excess pressure could be 5 to 25 MPa. Major gas accumulated in main producing bed of Shanxi Fm (P1s) and lower Shihezi Fm (P2x), because of two-fold control from capillary barrier and overpressure seal in upper Shihezi Fm (P2s). In the middle and southern districts, the two periods of Later Jurassic to the middle of Early Cretaceous, and middle of Later Cretaceous to Palaeocene are main periods of gas migration and accumulation, while they belong to readjustment period of gas reservoirs after middle of Neocene.WANG ZhenLiang CHEN HeLi 2007Science China Earth Sciences2007,50,z2:5
3Sensitivity of supplementation of thyroid hormone on treatmentof idiopathic short-stature children during therapy withrecombinant human growth hormone显示文摘This study aimed to evaluate the effects of thyroid hormone supplementation on growth rate of childrenwith idiopathic short stature (ISS) and low-normal serum free thyroxine FT4 who were receiving growth hormonetherapy. We selected 64 prepubertal children with FT4 levels in the lowest third of the normal range as the lowerFT4 group, and these children were divided randomly into two subgroups: L-thyroxine (L-T4)-treated subgroupwas treated with L-T4 (0.5-3.0 g/(kg, d)) from the beginning of the study, and the non-L-T4-treated subgroupreceived placebo. We also selected 39 ISS children with FT4 in the upper two-thirds of the normal range as thehigher FT4 group. During the first year, the lower FT4 group featured lower FT3, FT4, thyroid stimulatinghormone (TSH), and insulin-like growth factor-I standard deviation score (IGF-I SDS) and significantly lowerheight velocity (HV) compared with the higher FT4 group. However, in the lower FT4 group, the L-T4-treatedsubgroup presented higher FT4, FT3, TSH, and IGF-I SDS concentrations and significantly higher HV comparedwith children in the non-L-T4-treated subgroup. In children with ISS, the negative effect of thyroid hormonedeficiency on growth rate should be considered when FT4 level lies in the low-normal range prior to recombinant human growth hormone treatment.Wei Wang Shuqin Jiang Zhirui Cui Xiangyang Luo Lingli Shi Heli Zheng 2018Frontiers of Medicine2018,12,5:2
4Dynamic Resource Allocation in TDD-Based Heterogeneous Cloud Radio Access Networks显示文摘To fulfill the explosive growth of network capacity, fifth generation(5G) standard has captured the attention and imagination of researchers and engineers around the world. In particular, heterogeneous cloud radio access network(H-CRAN), as a promising network paradigm in 5G system, is a hot research topic in recent years. However, the densely deployment of RRHs in H-CRAN leads to downlink/uplink traffic asymmetry and severe inter-cell interference which could seriously impair the network throughput and resource utilization. To simultaneously solve these two problems, we proposed a dynamic resource allocation(DRA) scheme for H-CRAN in TDD mode. Firstly, we design a clustering algorithm to group the RRHs into different sets. Secondly, we adopt coordinated multipoint technology to eliminate the interference in each set. Finally, we formulate the joint frame structure, power and subcarrier selection problem as a mixed strategy noncooperative game. The simulation results are presented to validate the effectiveness of our proposed algorithm by compared with the existing work.Zhi Yu Ke Wang Hong Ji Xi Li Heli Zhang 2016China Communications2016,13,6:2

14Investigation on Modification of NaY Zeolite and Its Behaviors in Selective Adsorptive Desulfurization of FCC gasoline显示文摘NaY zeolite was modified with oxalic acid, and Ce(IV)Y(1) zeolite was obtained via liquid phase ion exchange between the modified NaY zeolite and cerium nitrate. The Ce(IV)Y(2) zeolite was obtained via liquid phase ion exchange between NaY zeolite and cerium nitrate. The performance of two Y zeolites [Ce(IV)Y(1) and Ce(IV)Y(2)] was compared through static selective adsorptive desulfurization of FCC gasoline at room temperature and normal pressure. The sulfur compounds and contents of the FCC gasoline were analyzed by microcoulometry and GC-SCD chromatogram. The results showed that the effect of adsorptive desulfurization of FCC gasoline achieved by Ce(IV)Y(1) zeolite was better than that of Ce(IV)Y(2) zeolite. The rate for adsorptive desulfurization of FCC gasoline by Ce(IV)Y(1) zeolite and Ce(IV)Y(2) zeolite was 85.0% and 62.4%, respectively. The Ce(IV)Y(1) zeolite could adsorb DMTs, which could not be adsorbed by Ce(IV)Y(2) zeolite. The rate of regeneration of extruded Ce(IV)Y(1)zeolite was 95.5%.Zhu Heli Song Lijuan Gao Xiang Wang Hongguo Zhang Xiaotong Sun Zhaolin (Liaoning Key Laboratory of Petrochemical Engineering, Liaoning University of Petroleum and Chemical Technology, Fushun 113001) 2009China Petroleum Processing & Petrochemical Technology2009,11,1:1

16Energy aware hierarchical cluster-based routing protocol for WSNs显示文摘Wireless sensor networks(WSNs) are emerging as essential and popular ways of providing pervasive computing environments for various applications. Unbalanced energy consumption is an inherent problem in WSNs, characterized by multi-hop routing and a many-to-one traffic pattern. This uneven energy dissipation can significantly reduce network lifetime. In multi-hop sensor networks, information obtained by the monitoring nodes need to be routed to the sinks, the energy consumption rate per unit information transmission depends on the choice of the next hop node. In an energy-aware routing approach, most proposed algorithms aim at minimizing the total energy consumption or maximizing network lifetime. In this paper, we propose a novel energy aware hierarchical cluster-based(NEAHC) routing protocol with two goals: minimizing the total energy consumption and ensuring fairness of energy consumption between nodes. We model the relay node choosing problem as a nonlinear programming problem and use the property of convex function to find the optimal solution. We also evaluate the proposed algorithm via simulations at the end of this paper.Wang Ke Ou Yangrui Ji Hong Zhang Heli Li Xi 2016The Journal of China Universities of Posts and Telecommunications2016,23,4:1
