We observe a sequence of two-level random telegraph signals (RTSs) in the drain/source current of a 1.7 nm gate oxide silicon metal-oxide-semiconductor field-effect transistor. The RTS magnitude is transformed into the apparent Debye length around a negatively charged oxide trap. We achieve excellent reproduction of the Debye data (40 down to 5 nm). This leads to the quantified area spanned by the dominant conductive percolation paths in the underlying two-dimensional electron gas (2DEG). We find that most of the 2DEG in inversion is recovered in a largest threshold voltage sample (similar to 0.35 V), while for the lowest threshold (similar to 0.15 V), a certain conductive filament is likely to occur. The gate direct tunneling current further corroborates the percolation picture. (c) 2008 American Institute of Physics.

Europium-activated barium magnesium aluminate (BaMgAl10O17:Eu (BAM)) phosphor particles were modified by surface coating with MgO using a polyol method. The photoluminescence (PL) properties of the MgO-coated BAM phosphors showed slightly improved blue-emission intensity compared to the unmodified ones, and reached a stronger peak intensity with 5.25% MgO coating, under vacuum ultraviolet (VUV) 147 nm excitation. Upon microwave irradiation on the MgO-coated BAM phosphors, the PL properties of the MgO-coated phosphors exhibited a much enhanced relative PL ratio, and a maximum relative PL ratio can be achieved when as high as 10.5% MgO was deposited on the phosphor surface. However, for mechanically ground phosphor powder, it was found that although the intensity of the MgO-coated BAM turned stronger with increasing MgO concentration under microwave irradiation, the purity of the resulting luminescence was slightly disrupted by the presence of a new peak near 470 nm, corresponding to BaMg3Al14O25 compound.

秤中藥的天平一邊比較重，另一邊比較輕，為什麼可以保持平衡呢，我們以身邊的小物品來實驗看看。力矩。衣架、線、湯匙、鉗子。 1. 將衣架剪斷，用最長的那段做支架，並用奇異筆標示等距的長度。 2. 將一根繩子綁在支架的中央，用手提著繩子的另一端，做為支點。然後在支點的左右兩側，在不同的位置，放置不同數目的湯匙，試著使支架保持平衡，不會傾斜。力矩（torque）是影響物體轉動的物理量，力矩的計算公式是「與支點的距離」乘以「重量」。當力矩的總和為零時，這個系統會維持轉動的平衡的狀態。在日常生活的應用包括﹕秤中藥的天平、國中化學課所使用的天平、以及小朋友玩的翹翹板。現在的菜市場都在使用電子秤，可以同時顯示重量及金額。在古時候（good old days），菜市場的攤販使用各式各樣的天平來稱重量，然後用心算的方式，來計算金額。那時候，因為怕被多收錢，所以客人的心算能力也很強。醫放系所高怡宣 / 陳金山老師秤中藥的天平（感謝台北市北投區尊賢街245號的鴻春參藥行提供樣品拍照）國中理化課所使用的天平（感謝台北市中正區太原路52號的尚樁五金行提供樣品拍照）在臺北市的國小及公園堙A翹翹板已經很少見了。（這張照片是在臺北縣永和市的四號公園拍照的）

A configuration of a linearized operational transconductance amplifier (OTA) for low-voltage and high-frequency applications is proposed. By using double pseudodifferential pairs and the source-degeneration structure under nano-scale CMOS technology, the norlinearity caused by short channel effect from a small feature size can be minimized. A robust common-mode control system is designed for input and output common-mode stability and thus reduces distortion caused by common-mode voltage variation. Mining ability can be achieved by using MOS transistors in the linear region. The linearity of the OTA is about -60-dB third-order inter-modulation (IM3) distortion for up to 0.9 V-pp at 40 MHz. This OTA was fabricated by the TSMC 180-nm deep n-well CMOS process. It occupies a small area of 15.1 X 10(-3) mm(2) and the power consumption is 9.5 mW under a 1.5-V supply voltage.

AlOx-ZnO core-shell nanorods arrays have been successfully synthesized by soaking the ZnO nanorods in the sol-gel solution of Al(NO3)(3) and NH4OH at room temperature. It was found that both crystal growth and morphology of the AlOx-ZnO core-shell nanorods are strongly influenced by the solution pH value. SEM image shows that the AlOx-ZnO core-shell nanorods can be perpendicularly grown on the ZnOf/Si substrate under the solution only with a pH value of 6-7. High-resolution TEM observation demonstrates that the structure of the AlOx layer is amorphous and the ZnO nanorod core remains single crystal. After annealed at 400 degrees C in N-2 atmosphere, a strong photoluminescence peak corresponding to blue emission (similar to 450 nm) was detected from the AlOx-ZnO core-shell nanorods that may result from the induced defects due to interaction between AlOx shell and ZnO nanorods.

An oxide-confined multileaf holey light-emitting diode (LED) in the 780 nm range is reported. The device is consisted of bottom distributed Bragg reflector (DBR), quantum wells QWs), and top DBR, with a multileaf holey structure within the p-ohmic contact ring for light extraction. The spontaneous emission from under the etched holes and internally reflected lights can be extracted and collimated out of the smaller etched leaf holes. High-resolution imaging studies indicate that the device emits with smaller beams mainly through the multileaf etched holes made it suitable for fiber-optic communications.

Polycrystalline silicon thin-film transistors (poly-Si TFTs) with a fluorinated silicate glass (FSG) passivation layer are proposed and demonstrated in this study. Experimental results reveal that the electrical characteristics can be improved by the incorporation of appropriate amounts of fluorine in the poly-Si film. The poly-Si TFTs with a FSG passivation layer show a high on-current, a low off-state gate-induced drain leakage (GIDL) current, a high field-effect mobility, and a suppressed kink effect, compared with the poly-Si TFTs with an undoped SiO(2) passivation layer. The presence of incorporated fluorine atoms from the FSG passivation layer in the poly-Si channel film can passivate the trap states at the grain boundaries. Furthermore, the incorporation of fluorine atoms can form stronger Si-F bonds near the source and drain sides to enhance the immunity against hot-carrier stress. In addition, the proposed poly-Si TFTs are easy to fabricate, have a low production cost, and are realized using a process compatible with modern TFT manufacturing technology.

Polycarbonate (PC) and crystalline polymer, isotatic polypropylene (iPP), are extruded using a mechanical blending extruder and a reciprocated mechanism for shearing is designed to perform long term shearing at a high shear rate in the packing stage. The present work investigates the effects of high shear rate shearing on the orientation of the phase morphologies and mechanical properties. The experiment utilises the technologies of specimen preparation and observation to examine the change in phase morphology. Additionally, the mechanical properties of injection moulded specimens under different processing conditions are measured. Experimental results show that adding a little PC into the iPP matrix, less than around 20%, increases the tensile strength of specimens. The orientation of the phase is improved and most of the tensile strength of the blends is increased after shearing. The tensile strength of the shearing specimens with a PC content of,25% exceeds that of the normal specimens of pure iPP. A higher iPP content corresponds to a higher tensile strength after shearing. This investigation also considers the possibility of using iPP/PC blends in industrial applications, indicating that shearing is valuable in industrial applications when the PC content in iPP/PC blends is 25%.
Design and analysis of a fault-tolerant coplanar gyro-free inertial measurement unit

This paper presents a novel design of a fault-tolerant, coplanar, and gyro-free inertial measurement unit (IMU) that consists of 13 single-axis linear accelerometers and can perform six degree-of-freedom (DOF) measurements for an object in motion. This design uses a combination of redundant accelerometers, an innovative real-time fault-identification technique, together with state-estimation techniques to facilitate robust six DOF measurements, even when some of its accelerometers produce faulty outputs. A design example indicates that the proposed fault-tolerant design and compensation algorithm can detect and correct the biased accelerometer outputs in real time. In this simulation example, the accelerometer measurement noise is assumed to be white and set at 0.1 m/s(2). The minimum detectable dc-offset value is 0.1 m/s(2), which is the same as the standard deviation of the accelerometer measurement noise. The compensated accelerometer outputs were used to construct an "observer-based" gyro-free IMU. The angular-velocity estimation accuracy is 4 x 10(3) rad/s, and the linear-acceleration accuracy is less than 0.24 m/s(2). The IMU output accuracy is not affected by the proposed fault-compensation algorithm.

The 3rd Generation Partnership Project (3GPP) defines IP Multimedia Core Network Subsystem (IMS) to support IP-based multimedia services. IMS utilizes protocols such as IP version 6 (IPv6), Session Initiation Protocol (SIP), and Real-time Transport Protocol (RTP) to deliver the multimedia content. This paper proposes an analysis tool referred to as SIPv6 Analyzer to investigate the IMS-related protocols during IMS service deployment. The SIPv6 Analyzer not only dissects the protocol headers but also provides user-friendly functions such as message flow generation and audio/video replay for IPv6, SIP, and RTP. We describe the design of the SIPv6 Analyzer and use examples to illustrate how it works. Copyright (C) 2006 John Wiley & Sons, Ltd.

Let Gamma denote a distance-regular graph with diameter d >= 3. By a parallelogram of length 3, we mean a 4-tuple xyzw consisting of vertices of Gamma such that partial derivative(x,y)=partial derivative(z,w)=1, partial derivative(x,z)=3, and partial derivative(x,w)=partial derivative(y,w)=partial derivative(y,z)=2, where partial derivative denotes the path-length distance function. Assume that Gamma has intersection numbers a(1)=0 and a(2)not equal 0. We prove that the following (i) and (ii) are equivalent. (i) Gamma is Q-polynomial and contains no parallelograms of length 3; (ii) Gamma has classical parameters (d,b,alpha,beta) with b <-1. Furthermore, suppose that (i) and (ii) hold. We show that each of b(b+1)(2)(b+2)/c (2), (b-2)(b-1)b(b+1)/(2+2b-c (2)) is an integer and that c (2)<= b(b+1). This upper bound for c (2) is optimal, since the Hermitian forms graph Her(2)(d) is a triangle-free distance-regular graph that satisfies c (2)=b(b+1).
陽明大學附設醫院蘭陽院區興建案通過

宜蘭的醫療品質不足，導致許多宜蘭人須千里迢迢北上至台北地區就診，東部醫療資源原本就不及西部。以東部為例，花蓮有屬於醫學中心等級的慈濟醫院，宜蘭地區卻沒有。經建會於一月20日通過教育部陳報的「陽明大學附設醫院蘭陽院區興建案」，總經費約為六十三億元，政府將於宜蘭市後火車站之「生物醫學產業特定專用區」內，興建本校附設醫院蘭陽院區。第一期工程預估於二○一三年完成，將可大幅提升宜蘭地區醫療品質。校方表示，希望聯合當地的醫療院所及社區，共同建立一個醫療服務與健康支持網絡，使宜蘭民眾能就近獲得方便而優質的醫療服務。「蘭陽院區」的發展主軸，將以重症醫療、心血管醫學、腫瘤醫學、神經醫學、胸腔醫學、老人醫學、社區醫學為主。蘭陽院區第一期工程計畫將包括：可容納四百張急性病床的醫療大樓、教學研究大樓、動力中心及地下停車場，而這也是宜蘭地區第一個大型醫學中心，預估在二○一三年完工啟用。可望提供重症醫療、生醫科技、教學研究實習等使用，第二期工程則包括醫護宿舍，預估二○一六年完工。除了蘭陽院區的興建案之外，從今年元月一日起，原有的署立宜蘭醫院，直接改制為陽明大學附設醫院之「新民院區」，提供蘭陽地區鄉親醫療照護服務。未來本校多元臨床教學資源，將可提供學生更豐富之訓練需求，培育更符合社會期待之未來醫生。秘書室編輯報導
接力補腦：一個「公門」共同學習計畫的緣起
(國立陽明大學, 2008-02-01)
郭文華
這個活動的緣起，是我們的彭惠媽媽（請參見葉璐嘉在《陽明電子報》課輔的文章，現收入課輔組網站）對目前寫作力衰退的憂心。而更遠的原因，則是姜安娜學務長的「快樂學習」。我一直認為校園的人文環境不只有學生才能享受；將青春與年輕完全付出的行政人員更需要在快樂中成長。公門畢竟不是好打混，而是好修行的場所。去年的十一月彭惠即將臨盆，卻還為同學的事情忙前忙後。當時，經過她的桌子，「教出寫作力」的出版訊息映入我的眼簾。寫作與閱讀，一直是我教學主題之一。我在通識的課，每學期都會有一些跟閱讀與寫作有關的課題。我叫住彭惠（要不然她不會停！），好奇地問她這個系列。而彭惠媽媽的反應也很簡單：「為了下一代」。這是一句有力的話：我覺得組員或許已經在繁忙的公文與電子郵件往返中，忘記從眼前飄來過去的文字，她的魔力與感性。王小滕教授於是，我突發奇想，請組員們讀這個專輯（目前已經出書），用接力的方式，看看大家怎樣看寫作力。因為書只有一本，因此我弄個流程，讓大家輪流看，一人寫一頁左右的感想，但鼓勵後面的人在寫心得之餘，也可以回應前面的人的想法。於是，我請本組的人氣王小瑄負責催稿，將文筆與資歷不同的組員交叉排列，希望可以激發出一些想法。這台「寫作力」的補腦列車，就這樣開動了。這台列車並沒有跑得很順利。畢竟，組員們也有各自的活動要忙，加上年底報帳事務紛至沓來，讓同仁們無法太過專注於這本雜誌。在這個時候，我就是這台列車的維修員，東敲敲西打打，總算沒有因此「誤點」。終於，在淑芬、小瑄、小璐、惠瑜之後，刊物終於抵達休養兩個月，復職上班的彭惠手上。此時，我也開始思考到底這台列車進站後，我們還能作什麼？我想到通識教育中心的王小滕教授。王老師在通識教授國文，強調作文的重要，在同學間早有佳評。而比較少人知道的是，王老師在重回學校攻讀學位前，曾在某公家機關擔任八年半的公務員，處理過成千上萬十分棘手的公文。於是，我邀請王老師過來跟我們的組員座談，分享寫作與閱讀的心得，並將這個專輯中，比較能說出寫作力概念，由清華大學寫作中心蔡英俊主任所執筆的文章給她參考。很幸運的，我們得到了王老師的首肯。討論時的剪影在此同時，我也有機會逐篇閱讀大家的心得。首先，我必須要說這些心得並沒有如我所預期有太多對話。事實上，它們還是個人性的文字，反映我們組員的訓練背景與文化關懷。淑芬一如她過去在電子報的呈現，有種自制而精確的風格。她提到口語與寫作的關係，也注意到閱讀與寫作力培養的重要。她沒有表現太多好惡，但似乎對此課題不感興趣。小瑄文如其人，蹦蹦跳跳，從中國到西方，從儒家到國中基測，不好跟。小璐是我們組裡的思想家，文氣縱橫，用語銳利如刀，旺盛的批判力往往拉出主題，直指台灣人比較不關心的階級差異與政策落實迷思。相較起來，惠瑜雖然看到類似問題，但敘述上比較不矯飾，有時粗糙有時謹慎，與她處理工讀金的態度相比，呈現有趣的對照。最後一站的彭惠敘事井井有條，顯示雍容的寫作氣度。她在文章中提到當時注意「寫作力」的動機，也提到提升同學寫作力的重要，為這次的接力心得分享劃下句點。親子天下專刊 - 教出寫作力特刊不過—活動還沒結束！在期末考週的某個上午，王老師一身黑衣連身裙，飄然現身課輔組。這，才是壓軸戲！王老師的分享，如惠瑜所記錄的，環繞在「文字是思想的呈現」這個概念上。使用文字的目的並非要舞文弄墨，而是要深化思想。因此，文字與思想一樣，需要時時的磨練與反芻，像庖丁解牛一樣，在混雜如血肉般模糊不清的事件中理出頭緒，並將其一件件排出順序，拉出之間的邏輯關係。公文如此，一般文章也是如此。而王老師也同意閱讀與寫作的關係。讀好的文章不但可以學習寫作的技巧，更可以從裡面看到思想的精華。王老師特別指出經典在閱讀寫作中的地位。經典之所以成為「經典」，就是在於其雋永性，無法一眼看盡。在我看來，經典的生命透過閱讀，與讀者的生命合而為一。在每個時候與心境讀一本經典，都可以感受書中的呼應。這就是經典的魅力。而活動也在此暫告段落。到底這樣的共同閱讀計畫算不算算成功？我不想為它打太高的分數。但是，這個長達一個多月的活動，確實為組員與我的寫作生命開了一道門，也將學務處念茲在茲的快樂學習與人文營造，延伸到為學校默默服務的職員上。在這個意義上，這是成功的嘗試。關於這本特刊的內容，請見博客來網路書店的介紹： http://www.books.com.tw/exep/prod/magazine/mag_retail.php?item=R030011144 郭文華
A novel process for forming an ultra-thin oxynitride film with high nitrogen topping

We have proposed an approach to grow ultra-thin oxynitride film with high nitrogen concentration (approximate to 13 at%) on the top and low interface state density (D-it = 2 x 10(10) cm(-2) eV(-1)). In general, a high-nitrogen oxynitride film provides a rather reliable and higher dielectric constant. In this method, oxynitride growth included three process stages-chemical oxide growth, nitridation and subsequent dry oxidation. By this technique, the films demonstrate the desirable nitrogen concentration profile and excellent properties in terms of low Dit, low leakage current, and high endurance in stressing. Better controllability in film thickness may be achieved because the oxidation rate of the nitride-chemical oxide is much smaller than that of the conventional oxide. Most importantly, this process is simple and fully compatible with current process technology. (C) 2007 Published by Elsevier Ltd.

The objective of this study is to design a novel cone-shaped lens cap on LEDs in order to achieve high optical efficiency in an ultra-thin directly lit RGB LED backlight unit (BLU) for large-sized LCD TVs. The use of the novel lens cap could play the role of a diffuser, a low light-efficiency component in a BLU, in order to gain higher efficiency and simultaneously provide satisfactory uniformity in light distribution. The novel cone-shaped lens is coated with aluminum on the outside surface of the cone for mirroring effects to reflect most of the LED emitted light horizontally and then reflect the light at the BLU boundaries, and then, finally to the output plane. In this way, bright spots on the output plane of the BLU can be avoided, leading to increased uniformity. Simulations were conducted to design and optimize varied aspects of the designed lens and BLU, including the cone angle of the proposed lens and the LED spacing (pitch). To further achieve color balance, a known Genetic Algorithm is used to search for the optimal angular placement of each RGB LED, resulting in better color balance. Finally, a prototype BLU for large-sized 37-in. LCD TVs with the proposed lens was built to verify the expected performance.

這是我們共同的名字：陽明人陽明電子報前身為陽明人報，創刊於民國80年12月20日（五），當時的發行人韓院長詔華在發刊詞「這是我們共同的名字：陽明人」中說明這是一份「聯繫全體陽明人的刊物」，目的是為了「報導校園內的要聞，介紹校友的近況與服務心得，溝通不同的意見，讓『陽明人』得以進一步認識陽明。」陽明電子報首航的刊頭設計是以達文西所繪的人體比例圖，加上現代科技電子化的創新( 普普藝術 ) 而成隨著時代遞嬗，電子傳播已蔚為趨勢，陽明人報乃於90年2月14日更名為陽明電子報，正式晉身為電子媒體。肩負陽明校園及校際活動訊息之交流與傳遞等責任，陽明電子報仍一本增進陽明人互動之成立宗旨，目前每月發報兩次，定期報導陽明焦點新聞、行政會報摘要、各處室訊息、院系所傳真、社團動態及陽明人；另外不定期刊載特別報導，如30而立系列報導、安全特刊、非洲紀行等。陽明電子報希望借由這些報導，建構起聯繫所有師生的橋樑。陽明電子報編輯小組敬啟
