In this paper, we demonstrated a far-field scheme for the manipulation of locally excited surface plasmon polaritons (SPPs). This scheme features steering and shaping capabilities, and relies on the focusing of a high numerical aperture, in conjunction with spatially inhomogeneous polarized (SIP) illumination. We were able to control the propagation and direction of SPPs, via the field distribution of polarization at the entrance pupil, without the need for an aperture, protrusion or any other near-field features. Depending on the axial position of the focus, the field distribution of excited SPPs revealed either counter-propagating interference or a multi-casting plasmonic source. The results of near-field imaging demonstrated the versatility of the SPPs, showing strong agreement with the predictions made during simulations. Due to the simplicity and versatility of the proposed method, we believe that it could have a significant impact the processes employed in the excitation of a variety of SPPs.

For advanced CMOS processes, inverse lithography promises better patterning fidelity than conventional mask correction techniques due to a more complete exploration of the solution space. However, the success of inverse lithography relies highly on customized cost functions whose design and know-how have rarely been discussed. In this paper, we investigate the impacts of various objective functions and their superposition for inverse lithography patterning using a generic gradient descent approach. We investigate the most commonly used objective functions, which are the resist and aerial images, and also present a derivation for the aerial image contrast. We then discuss the resulting pattern fidelity and final mask characteristics for simple layouts with a single isolated contact and two nested contacts. We show that a cost function composed of a dominant resist-image component and a minor aerial-image or image-contrast component can achieve a good mask correction and contour targets when using inverse lithography patterning.

The present invention discloses a background calibration system and method for calibrating the non-linear distortion of the amplifier. The calibration method in the present invention includes: generating random sequences and inputting the random sequences in different amount and different sets into an amplifier; amplifying the random sequences and detecting linear and non-linear coefficients; quantizing the output linear signal from the amplifier, and generating a digital output signal; multiplying the digital output signal to generate a high-order signal; generating an estimated non-linear error for the amplifier by multiplying the high-order signal with the estimated non-linear coefficient; adding the non-linear signal with the digital output signal to generate a linear output signal; calculating the random value from the parameter extractor to determine the occurrence of non-linear distortion in the circuit, and further adjusting the non-linear coefficient to calibrating the amplifier.

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。
Diminished cage effect in solid p-H(2): Infrared absorption of CH(3)S observed from photolysis in situ of CH(3)SH, CH(3)SCH(3), or CH(3)SSCH(3) isolated in p-H(2) matrices

We report the infrared absorption spectrum of the methylthio (or thiomethoxy) radical, CH(3)S (X(2)E(3/2)), produced via photodissociation in situ of three precursors CH(3)SH, CH(3)SCH(3), and CH(3)SSCH(3) isolated in solid p-H(2). The common absorption features observed with similar intensity ratios in each experiment are assigned to CH(3)S. The wavenumbers of these features agree satisfactorily with those predicted with a spin-vibronic Hamiltonian accounting for the anharmonic effects and the Jahn-Teller effects to the quartic term [A. V. Marenich and J. E. Boggs, J. Chem. Theory Comput. 1, 1162 (2005)]. In addition to an absorption line at 724.2 cm(-1), corresponding to a transition of 3(1) previously determined to be 727 cm(-1) from fluorescence spectra of gaseous CH(3)S, we identified fundamental transitions 6(1)(a(1)) at 771.1, 6(1)(e) at 1056.6, 5(1)(a(1)) at 1400.0, 4(1)(a(1)) at 2898.4 cm(-1), and several combination and overtone transitions. In contrast, photolysis of CH(3)SSCH(3) isolated in solid Ar produces mainly H(2)CS, CH(3)SH, and CS(2), but no CH(3)S. These results demonstrate the feasibility of using photolysis in situ of precursors isolated in solid p-H(2) to produce free radicals by taking advantage of the diminished cage effect of the matrix.

An acoustic camera comprises a first sound pick-up device, a second sound pick-up device, and a switch. The switch is respectively connected to the first sound pick-up device and the second pick-up device and used to select the first sound pick-up device or the second sound pick-up device to reconstruct the sound field of the sound source of a detected object. The first sound pick-up device has a first microphone array, and the first microphone array is a near-field uniform microphone array. The second sound pick-up device has a second microphone array, and the second microphone array is a far-field non-uniform microphone array.

HTS hit 7 was modified through hybrid design strategy to introduce a chiral side chain followed by introduction of Michael acceptor group to obtain potent EGFR kinase inhibitors 11 and 19. Both 11 and 19 showed over 3 orders of magnitude enhanced HCC827 antiproliferative activity compared to HTS hit 7 and also inhibited gefitinib-resistant double mutant (DM, T790M/L858R) EGFR kinase at nanomolar concentration. Moreover, treatment with 19 shrinked tumor in nude mice xenograft model.

Employing mix-and-match lithography of I-line stepper and e-beam direct writing, independent double-gated poly-Si nanowire thin film transistors with channel lengths ranging from 70 nm to 5 mu m were fabricated and characterized. Electrical measurements performed under cryogenic ambient displayed intriguing characteristics in terms of length dependent abrupt switching behavior for one of the single-gated modes. Through simulation and experimental verification, the root cause for this phenomenon was identified to be the non-uniformly distributed dopants introduced by ion implantation.

在重新尋找生活目的的一年半的時間裡，她遊歷了義大利、印度、印尼。在義大利，美味的匹薩、咖啡、甜食，讓她快樂起來，不再沉湎那段剪不斷理還亂的婚外情；在印度，修煉的道場裡，她體會靜默祈禱的力量，與自我心靈之神溝通，寬恕自己；在印尼，她放下，她前行，相信自己還能有永恆愛的能量。

近年來，台灣唱片界出現一股新風潮，許多藝人一開始可能是以廣告、戲劇或身為話題性人物等各式各樣的方式出道，但當他們在這些領域表現傑出，受到大家關注並火速竄紅之後，公司便會安排他們發行專輯。演藝圈以「爆紅與否」這樣子的依據為能否發行唱片的準則，似乎不是那麼專業，讓人不禁懷疑起台灣「歌手」的素質。

2008年，《海角七號》上映，形成一股旋風，接續著這股熱潮，《囧男孩》也創下佳績。於是2008年被稱為「國片復興年」，但綜觀現況，不禁讓人懷疑，國片真的重新蓬勃發展了嗎？或者這只是一股尾隨《海角七號》而來的熱潮，終究是曇花一現呢？
