We report an experimental study of a fingering pattern formation which occurs during the spreading of an immiscible thin ferrofluid drop subjected to a radial magnetic field. Our results indicate that this ferrohydro-dynamic system works as a magnetic analog of conventional spin coating, where centrifugal driving is replaced with a magnetic body force induced by the radial applied field. In this context, a magnetically tunable pattern selection mechanism is proposed in which the shape and number of the arising fingered structures can be properly controlled.

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。

Robust magnetic polarons in type-II (Zn, Mn) Te/ZnSe magnetic quantum dots

We present a magneto-optical study of magnetic polarons in type-II (Zn, Mn) Te quantum dots. The polarons are formed due to the exchange coupling between the spins of the holes and those of the Mn ions, both of which are localized in the dots. In our photoluminescence studies, the magnetic polarons are detected at temperatures up to similar to 150 K, with a formation energy of similar to 40 meV. The emission from these dots exhibits an unusually small Zeeman shift with applied magnetic field (similar to 2 meV at 8 T) and at the same time a very large circular polarization. We attribute this apparently contradictory behavior by a low and weakly temperature-dependent magnetic susceptibility due to antiferromagnetic coupling of the Mn spins.

We have studied the photochromic reaction of p-hydroxycinnamic-thiophenyl ester in the microcrystalline state We attributed the fluorescence spectral evolution of the microcrystal under UV irradiation to the photoinduced trans-to-cis isomerization The photocyclic behavior of the chromophore was demonstrated by cis-to-trans back reaction under a subsequent visible light irradiation In addition the [2 2] topochemical photocyclodimer was observed as another photoproduct It is considered that the cooperative photoisomerization is initiated at the local lattice distortion and free spaces around the [2 + 2] cyclodimer near the crystal sui lace and the photoisomerization induces larger lattice deformation and further photoisomerization in the interior of the crystal

A biosensor applicable to an environment suitable for biosensing is provided, which is a solid-state element for performing detections in an aqueous environment. The biosensor at least includes a biosensing layer, a light-emitting diode and a photodiode. The biosensing layer causes changes in the light-emitting property thereof after absorbing, adsorbing and/or bonding with a biological substance released during in vivo signal transduction in an organism, and the rays of light generated by excitation of the light-emitting diode causes the biosensing layer to emit fluorescence. After the fluorescence is absorbed by the photodiode, it can be converted into an interpretable photocurrent signal. Afterwards, the meaning of the in vivo signal transduction can be understood by interpretation of the photocurrent signal.

This paper analyzes the effects of tourist nationalities on the cost efficiency of international tourist hotels (ITHs) in Taiwan. From 1996 to 2007, the numbers of overseas Chinese and European tourists have shown significantly negative effects on cost efficiency, while the numbers of Taiwan Nationals, North American, Japanese, and Australian tourists have had significantly positive effects on cost efficiency. The numbers of the rest of Asia tourists (including mainland Chinese) have no significant effects on cost efficiency. Furthermore, the chain system and shorter distances to the nearest international airport significantly improve cost efficiencies.
PARAMETER ADJUSTMENT DEVICE AND METHOD THEREOF
(2010-11-18)

A parameter adjustment device and method thereof for a stimulator is disclosed. The parameter adjustment device comprises a generation unit, a user interface and a process unit. The generation unit generates a test MAP based on a current MAP. The user interface displays the current MAP and the test MAP for choosing one of them as the preferred MAP, and displays a major and a minor for choosing again, the major and the minor is defined as a significant difference and a little difference between the test MAP and the current MAP respectively. The process unit computes the acceptance probability of the preferred MAP based on a major or minor probability correspondence relationship and determines a next MAP by comparing the acceptance probability with the test probability. When one of the termination conditions is satisfied in an iterative operation, the next MAP is outputted as the best MAP.
Cathodoluminescence studies of GaAs nano-wires grown on shallow-trench-patterned Si

The optical properties of GaAs nano-wires grown on shallow-trench-patterned Si(001) substrates were investigated by cathodoluminescence. The results showed that when the trench width ranges from 80 to 100 nm, the emission efficiency of GaAs can be enhanced and is stronger than that of a homogeneously grown epilayer. The suppression of non-radiative centers is attributed to the trapping of both threading dislocations and planar defects at the trench sidewalls. This approach demonstrates the feasibility of growing nano-scaled GaAs-based optoelectronic devices on Si substrates.

「讓座，是一種美德。」學習如何禮讓他人，相信是大部分人從小就被家庭、學校灌輸的道德教育。前陣子八月才剛發生了在公車上「老翁促讓博愛座，清大生反揮拳」的社會事件，引起群眾、網友多方面的撻伐與熱烈討論，各電視台也接連幾日頻繁報導類似的新聞事件，並爭相邀請學者、評論家以及主持名嘴在節目上討論。而近日又再發生有學生於捷運車廂內橫躺，連占了三個位置，經他人勸說後依然不為所動的報導，使得「讓座文化」成為近來人們探討社會秩序與價值觀等議題的導引線。

小時候的國語課本裡說每一個人都是社會的一顆小螺絲釘，提供社會這個大齒輪使它不停轉動。社會公轉，我們也自轉，就這樣周而復始沒有停歇。然而，黃玠不將自己投身進入這個巨大的轉輪裡，反將自己裝進音樂這個小機器裡，努力讓音樂不停轉動並且發光發熱。
