The silver Y moth Autographa gamma undertakes windbome spring and fall migrations between winter breeding re- gions around the Mediterranean and summer breeding regions in northern Europe. Flight behaviors facilitating these migrations include：（i） selection of seasonally-favorable tailwinds; （ii） flying at the altitude of the fastest winds; （iii） adopting flight headings that partially counteract crosswind drift; and （iv） seasonal reversal of preferred directions between spring and fall. In the UK, ra- dar measurements indicate that migratory activity is pronounced during the spring and fall, but is usually very low during mid- summer （July）. However, an atypically intense period of high-altitude flight was recorded during July 2006, and in this study we compare the flight behavior of A. gamma during these midsummer movements with the more typical spring and fall migrations. During July 2006, activity was most intense at significantly lower altitudes than occurred in spring or fall, and was not associated with the height of the fastest winds; consequently displacement speeds were significantly slower. The most striking difference was an absence of tailwind selectivity in July with windborne movements occurring on almost every night of the month and on tailwinds from all directions. Finally, orientation behavior was quantitatively different during July, with significantly greater dis- persion of flight headings and displacements than observed in spring and fall. We discuss mechanisms which could have caused these differences, and conclude that a lack of appropriate photopcriod cues during development of the summer generation resulted in randomly-oriented ＇dispersive＇ movements that were strikingly different from typical seasonal migrations .

很多研究者都将西藏传统戏剧阿吉拉姆的起源归于佛教仪式,甚至在阿吉拉姆和藏传佛教仪式"羌姆"表演之间寻找某种嫡传关系。笔者以为阿吉拉姆诞生虽然始于汤东杰布的戏剧实践,然而其起源有着更久远的背景和传统,甚至可以追溯至前佛教时期的仪式歌舞或民间祭祀活动。通过对阿吉拉姆表演中第一段"温巴顿"的观察和分析,可以窥见阿吉拉姆的起源、演变及正式诞生的过程。

The effects of Ho substitution for Nd on the microstructure, corrosion resistance and thermal stability of the Nd-Fe-B magnets were investigated. The（Nd,Ho）-O phase was formed with increasing Ho substitution. The results of potentiodynamic polarization and highly accelerated stress test show improved corrosion resistance with increasing Ho substitution. The optimum mass loss 0.29 mg/cm^2 is ***, the average temperature coefficients for remanence and coercivity in the range of 25-150℃are both closer to zero, indicating improved thermal stability. The mechanisms for the improved corrosion resistance and thermal stability are discussed in relation to the microstructure featuring the（Nd,Ho）-O phase.

Chinese Optics Letters 2008年第12期6卷 876-878页

We present a novel confocal laser method （CLM） for precise testing of the dioptric power of both positive and negative intraocular lens （IOL） implants. The CLM principle is based on a simple fiber-optic confocal laser design including a single-mode fiber coupler that serves simultaneously as a point light source used for formation of a collimated Gaussian laser beam, and as a highly sensitive confocal point receiver. The CLM approach provides an accurate, repeatable, objective, and fast method for IOL dioptric power measurement over the range from 0 D to greater than ±30 D under both dry and in-situ simulated conditions.

Status and Perspective of Demand Resource Market in Korea＇s Electric Power Industry

引用

Journal of Energy and Power Engineering 2012年第4期6卷 591-600页

作者： don Hur Department of Electrical Engineering Kwangwoon University Seou1139-701 Korea

This paper calls attention to the demand resource market in Korea which opened in 2008 to reduce customers＇ consumption at critical times and, at the same time, secure the load that can be shut down. In Korea, the demand resource market is operated by either forward market or spot market. The discussion here is limited to the operations of the demand resource spot market. As the demand response program has matured in the smart grid environment, KPX （Korea Power Exchange） will shortly complete the development of the real-time demand resource trading system, taking into account an integrated dispatch system.
