The present work deals with 12-bit Nyquist current-steering CmOS digital-to-analog converter (DAC) which is an essential part in baseband section of wireless transmitter circuits. Using oversampling ratio (OSR) for the proposed DAC leads to avoid use of an active analog reconstruction filter. The optimum segmentation (75%) has been used to get the best DNL and reduce glitch energy. This segmentation ratio guarantees the monotonicity. Higher performance is achieved using a new 3-D thermometer decoding method which reduces the area, power consumption and the number of control signals of the digital section. Using two digital channels in parallel, helps reach 1-GSample/s frequency. Simulation results show that the spurious- free-dynamic-range (SFDR) in Nyquist rate is better than 64 dB for sampling frequency up to 1-GSample/s. The analog voltage supply is 3.3 V while the digital part of the chip operates with only 2.4 V. Total power consumption in Nyquist rate measurement is 144.9 mW. The chip has been processed in a standard 0.35 μm CmOS technology. Active area of chip is 1.37 mm2.

目的：检测术前应用坦索罗辛对全麻白内障患者尿潴留的预防作用。方法：对67名男性患者行全麻白内障手术，口服坦索罗辛，每日0．4mg （32例）或安慰剂（35例）。比较两组术后尿潴留和软盘虹膜综合征发生率。结果：两组患者年龄，坦索罗辛组：68．16±8．72岁；安慰剂组：71．37±8．60岁，（P＝0．38）。术后坦索罗辛组尿潴留发生率较低（3．1％vs48．6％，P＜0．001；Odds ratio＝29．28，95％CI 3．59～238．79）。安慰剂组中1例（2．9％）发生软盘虹膜综合征（P＝0．52；Odds ratio＝1．03，95％CI 0．97～1．09）。结论：全麻白内障手术前口服坦索罗辛可有效防止术后尿潴留，而不增加软盘虹膜综合征发生的风险。

BACkGROUND AND OBJECTIVE: To compare the use of cyclocryotherapy and diode laser cyclophotocoagulation for the treatment of uncontrolled intraocular pressure. P ATIENTS AND mETHODS: Seventy consecutive patients (70 eyes)-treated for high, u nresponsive intraocular pressure during a 4-year period with cyclocryotherapy ( n=38) or diode laser cyclophotocoagulation (n=32) with a follow-up period of at least 3 months (mean follow-up=15.7 months) were compared for intraocular pres sure, visual acuity, and complication rate. RESULTS: mean intraocular pressure w as reduced from 40.9 ±11.9 to 20.5 ±10.3 mm Hg in the cyclocryotherapy group, and from 35.9 ±9.3 to 21.3 ±10.7 mm Hg in the cyclophotocoagulation group. Int raocular pressure was controlled in 60.5%and 62.5%of eyes, respectively. Deter ioration in visual acuity occurred in 31.5%of the cyclocryotherapy group and 37 .5%of the cyclophotocoagulation group. Severe visual loss to no light perceptio n was noted in 6 eyes and 2 eyes, respectively, and phthisis bulbi in 2 eyes in the cyclocryotherapy group (5.2%) and 1 eye in the cyclophotocoagulation group (3.1%). CONCLUSIONS: Cyclocryotherapy and diode laser cyclophotocoagulation are equally effective in decreasing intraocular pressure in patients with persisten t uncontrolled glaucoma, with a lower rate of complications associated with diod e laser cyclophotocoagulation.

2005年对野生的杏黄兜兰进行了温室栽培试验,并于2006年4月用典型抽样法对杏黄兜兰的生境进行了调查研究。杏黄兜兰天然分布集中在怒江流域,垂直分布范围超过现有资料记载的海拔2100 m。杏黄兜兰分布区为典型的亚热带山地气候,在以石灰岩为基质发育的土壤上,杏黄兜兰丛生于高山栎-杜鹃次生灌木群落内腐殖质丰富的林下,杏黄兜兰易栽培成活。不同遮荫和施肥处理的杏黄兜兰的叶绿素含量差异不显著,但存在随着遮荫强度增加而增加的变化趋势;不遮荫和单层遮荫处理下,叶绿素含量随着N肥中的含N量增加而增加;不同遮荫和施肥处理对杏黄兜兰的叶片长度和叶片宽度影响不大,但不同遮荫强度对杏黄兜兰叶片的厚度有较大影响。

气候变化和自然灾害对人类社会造成了多方面的影响。城市规划与设计是应对气候变化和防灾减灾的有效手段。然而,由于城市基础设施系统间的关联性,城市系统遭受的由气候变化引发的风险及影响尺度繁多且复杂。规划者需要了解并评估自然灾害对关联基础设施的潜在风险及可能产生的连锁反应,制定应对这些影响的适应性规划策略。本文讨论了将社会和实体基础设施系统纳入适应性防灾减灾规划过程的机遇和挑战。适应性防灾减灾规划过程包括气候灾害评估、适应性规划目标确立、适应性战略制定及适应性政策实施。城市大数据和高性能计算资源的广泛使用可辅助城市规划者和决策者更好地应对气候变化和自然灾害所带来的复杂影响。为成功构建结合关联基础设施系统的适应性防灾减灾规划,需要解决气候预测的不确定性、适应性规划的制度性问题,以及城市大数据的代表性存疑等问题。上述问题可通过多学科专家共同合作,不同层级政府部门相互协调,以及开发更完善的数据保护机制和更健全的数据检测方法解决。
