Because of the nonuniform electric field of the in-plane-switching cell in the thickness direction, an accurate and efficient way for evaluating the Kerr constant of blue-phase liquid crystal (BPLC) needs to be developed. This study demonstrates a method for evaluating the Kerr constant by measuring the off-axis-induced retardation (R(th)) change in normal vertical field cells using a commercial polarimeter. The angle-dependent behavior of the R(th) change is observed as an electric-tunable positive C retarder. In this paper, a sigmoid fitting model has been chosen for calculating the Kerr constant for considering the very small intrinsic birefringence of the BPLC. (C) 2011 Optical Society of America

Controlling chemical reactions within a small space is a significant issue in chemistry, and methods to induce reactions within a desired position have various potential applications. Here we demonstrate localized, efficient photopolymerization by radiation pressure. We induced a one-photon UV polymerization of liquid acrylate solutions in the optical-trapping potential of a focused near-IR (NIR) laser beam, leading to the confinement of solidification to a minute space with dimensions smaller or equal to one-fifth of the wavelength of the NIR laser. Our approach can produce solidification volumes smaller than those achievable with conventional one-photon polymerization, thus enabling the production of tiny polymeric structures that are smaller than the diffraction limit of the trapping light. This is the first demonstration of a radiation pressure effect on a photochemical reaction.

課程首頁本課程是由交通大學新文藝復興閱讀計畫提供。 96 年 8 月當各大學紛紛摩拳擦掌準備迎接新生的同時，交通大學校長吳重雨則因為一則來自於七月份泰晤士報，有關於英國首相布朗公布其夏日讀書清單的新聞中，看到了他對知識的尊重。在這同時，吳重雨校長也思考著，要如何為學生準備追求知識的環境和激發他們對知識的尊重與喜愛。台積電張忠謀董事長曾陳述他 18 歲進入哈佛那一年，博覽文史哲理工經典群籍，至此奠定了他求知的基礎，並借海明威名言，將其改為「哈佛這一年為人生可帶走的盛宴。」吳重雨校長以張董事長的學習為借鏡，認為學生固然能藉由自我閱讀的方式學習到豐沛的知識，但透過名人、大師親臨現場地介紹經典書籍，更能加深學子們對於書籍的認識與興趣，這也是「新文藝復興閱讀計劃」 ( 以下簡稱 : 「經典名著選讀」 ) 活動展開籌劃的緣由。於是，吳重雨校長便積極敦請「交大通識教育委員會」，接手籌備本計劃的相關活動，而該中心也成為實際施行本計畫的策動、開課以及認證單位。至此，期許交大學子藉由閱讀、聽講來提昇人文素養、開拓視野的「新文藝復興閱讀計劃」，就此展開。

The present invention provides an electrical stimulation method and apparatus to stimulate nerve fibers, turning on suitable combination of adjacent electrodes simultaneously to form virtual channels based on predetermined rules, so that the stimulation signal will generate or evoke a nerve response spectrum that matches the original signal spectrum presented as the input sound. The method includes the steps of receiving a sound signal by a receiving unit; dividing the received sound signal into a plurality of frequency bands by a processing unit; extracting a spectral peak from each of the frequency bands and determining a stimulation sequence of frequency bands by the processing unit; and selectively driving a plurality of electrode groups in a plurality of cycles based on the stimulation sequence of frequency bands and a determination rule by the processing unit, so that the nerve response that matches the original signal will be generated.

Ozonolysis of bis-endo-diacylbicyclo[2.2.1]heptenes 3a-d at -78 degrees C in dichloromethane methanol gave the hydroperoxides 6a-d in 70-80% yields. Ozonolysis of bis-endo-diacetylbicyclo[2.2.2]octene 15 and bis-endo-diacetyl-7-oxabicyclo-[2.2.1]heptene 16 under the same reaction conditions gave the hydroperoxides 17 and 18, respectively. The intramolecular sequential nucleophilic addition of the carbonyl groups to the carbonyl oxide group was observed for the first time and was found to be faster than the intermolecular nucleophilic addition of a methanol molecule to the carbonyl oxide group. Ozonolysis of compound 23 in CH(2)Cl(2)-MeOH at -78 degrees C followed by reduction with Me(2)S gave compounds 24 and 25, in which the stereochemistry of the methoxyl groups was determined by X-ray analysis.

Imaging of Zebrafish In Vivo with Second-Harmonic Generation Reveals Shortened Sarcomeres Associated with Myopathy Induced by Statin

We employed second-harmonic generation (SHG) imaging and the zebrafish model to investigate the myopathy caused by statin in vivo with emphasis on the altered microstructures of the muscle sarcomere, the fundamental contractile element of muscles. This approach derives an advantage of SHG imaging to observe the striated skeletal muscle of living zebrafish based on signals produced mainly from the thick myosin filament of sarcomeres without employing exogenous labels, and eliminates concern about the distortion of muscle structures caused by sample preparation in conventional histological examination. The treatment with statin caused a significantly shortened sarcomere relative to an untreated control (1.73 +/- 0.09 mu m vs 1.91 +/- 0.08 mu m, P<0.05) while the morphological integrity of the muscle fibers remained largely intact. Mechanistic tests indicated that this microstructural disorder was associated with the biosynthetic pathway of cholesterol, or, specifically, with the impaired production of mevalonate by statins. This microstructural disorder exhibited a strong dependence on both the dosage and the duration of treatment, indicating a possibility to assess the severity of muscle injury according to the altered length of the sarcomeres. In contrast to a conventional assessment of muscle injury using clinical biomarkers in blood, such as creatine kinase that is released from only disrupted myocytes, the ability to determine microstructural modification of sarcomeres allows diagnosis of muscle injury before an onset of conventional clinical symptoms. In light of the increasing prevalence of the incidence of muscle injuries caused by new therapies, our work consolidates the combined use of the zebrafish and SHG imaging as an effective and sensitive means to evaluate the safety profile of new therapeutic targets in vivo.

四處可見的學校，其實背後都有不為人知的一面，尤其是相形封閉的國中、國小，私底下運作的黑手更多。但畢竟這是個基層又龐大的體制，腐敗已經有相當的一段時間了，所以就算是想改也無計可施。

旅行、留學、遊學是台灣年輕人探索世界、打開國際視野的傳統途徑，近幾年，漸漸轉向公益旅行、打工度假、國外實習等多元方式，生活水準提升後，普通的出國旅遊已經無法滿足一般人的需求了，出國不再只是走馬看花、拍拍照片而已，而是要了解當地的文化與生活方式。在年輕人心目中，公益旅行比海外遊學便宜，也比自助旅行更深入異國，是兼具服務責任與旅遊樂趣的選擇！
