We show an artificially engineered electret with Si nanocrystals embedded in mesoporous silica for nonvolatile memory. We attribute the polarization to from polar layers lying at the interfaces between one-side bonded Si nanocrystals and mesoporous silica matrix. Under external field, the Si nanocrystals could be displaced in the porechannels causing displaced charge distributions and therefore a field-controllable electric polarization. Nonvolatile memory is demonstrated with a metal-oxide-semiconductor field-effect transistor. (C) 2009 American Institute of Physics. [doi:10.1063/1.3240888]

This study reports the synthesis of morphology-controlled BaTiO(3) nanostructures such as spherical, cube-shaped and rod-shaped BaTiO(3) using a molten-salt synthesis method. This method synthesized products from a reaction of BaO/BaCO(3)(+) and TiO(2) with a eutectic mixture of NaCl-KCl flux at 700 degrees C for 1 h. The experiment used powder X-ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy to investigate the structure and morphology of the products. Moreover, the current work also provides a proposed synthetic mechanism of BaTiO(3) in the molten salt to illustrate the in situ transformation mechanism of BaTiO(3) nanostructures in the reaction, The results of the study revealed that the initial shape of the titania and the dissolution rate of the initial precursors critically determine the shapes of the final products.

Quantum confinement effects on hole mobility in silicon and germanium double gate p-channel metal-oxide-semiconductor field-effect transistors (MOSFETs) are studied by using a Monte Carlo method. Uniaxial stress and channel/substrate orientation effects are considered. Our result shows that the hole mobility in a (100)/[110] silicon well decreases with a decreasing well thickness, which is in agreement with the experimental result. The hole mobility in a germanium channel MOSFET, however, exhibits a peak in a sub-20 nm well because of the interplay between intrasubband and intersubband scatterings.

Let m be a positive integer and let G be a graph. A set M of matchings of G, all of which of size m, is called an [m]-covering of G if boolean OR(M is an element of M) M = E(G). G is called [m]-coverable if it has an [m]-covering. An [m]-covering M such that vertical bar M vertical bar is minimum is called an excessive [m]-factorization of G and the number of matchings it contains is a graph parameter called excessive [m]-index and denoted by chi([m])' (G) (the value of chi([m])'(G) is conventionally set to infinity if G is not [m]-coverable). It is obvious that chi([1])'(G) = vertical bar E(G)vertical bar for every graph G, and it is not difficult to see that chi([2])'(G) = max{chi'(G), inverted right perpendicular vertical bar E(G)vertical bar/2inverted left perpendicular} for every [2]-coverable graph G. However the task of determining chi([m])'(G) for arbitrary m and G seems to increase very rapidly in difficulty as m increases, and a general formula for m >= 3 is unknown. In this paper we determine such a formula for m = 3, there by determining the excessive [3]-index for all graphs.

This invention discloses a data inquiry system for three-dimensional location-based image, video, and information, which comprises a client device and a remote server. The client device provides space parameters and lens parameters to the remote server through a transmission module. The remote server determines a space inquiry range by the space parameter and lens parameter, inquires an object data of an object space position parameter at the space inquiry range, shows the object data in an image data displayed by the client device to facilitate users to identify the desired viewing object, and further inquires the object data and related image and/or video data.

We demonstrate the feasibility of modulating and improving the separation of photoinduced charge carriers of CdS-M nanoheterostructures through partial replacement of S with two group 16 elements of larger atomic size, Se and Te. With the incorporation of Se or Te into the US nanowires (NWs), the defect states of the US NWs were effectively passivated, enabling a fuller extent of participation of the photoinduced electrons in the charge separation process, thus resulting in a more pronounced photoluminescence quenching and photocurrent depression for the CdS(1-x)Se(x) and CdS(1-x)Te(x) NWs. The present study provides a facile way of improving the photocatalytic efficiency of US through the improvement in retarding the recombination of photoinduced charge carriers.

一種虹膜辨識方法，藉由匹配搜尋演算法來簡化虹膜特徵的擷取與重組，以縮減每筆虹膜特徵向量在資料庫裡所佔之空間並同時維持虹膜辨識的準確度。該虹膜辨識方法同時包含了一個虹膜地方化元件與一個特徵比對元件。地方化元件藉由眼睛不同部位的色澤來定義出虹膜範圍。然後使用匹配搜尋演算法來提取虹膜的主要特徵並化為一系列的特徵向量。在匹配搜尋法後，虹膜影像可以由一系列的原子組合來表示。每一個原子包含了方位，基部與振幅等資訊。最後藉由比對兩個虹膜的特徵向量來決定他們使否屬匹配。

當整個世界變成一座廢棄的大型遊樂場，每個白日灰濛過前日，我們應該在這微光起落的世界邁步向前，或是蹣跚地向未知的黑暗走去？《長路》 (原名：The R oad) 被譽為是哥馬克‧麥卡錫(Cormac McCarthy)獻給全世界的一首優美輓歌，同時也是他題獻給自己八歲兒子的一本書。本書承襲了麥卡錫一貫洗鍊細膩的文字，將文明終結後的荒涼世界描寫地殘酷幽暗，書中的每一刻更是充滿著對生命的惶恐與矛盾。在《長路》這片死寂慘暗的世界裡，父親與孩子細緻的感情，變成讀者眼中唯一的光彩與希望，也成就了這部末世寓言獨特的溫柔。
