In this report, the influence of the intrinsic transitions between bound-to-delocalized states (crossed states or quasicontinuous density of electron-hole states) on photoluminescence excitation (PLE) spectra of InAs quantum dots (QDs) was investigated. The InAs QDs were different in size, shape, and number of bound states. Results from the PLE spectroscopy at low temperature and under a high magnetic field (up to 14 T) were compared. Our findings show that the profile of the PLE resonances associated with the bound transitions disintegrated and broadened. This was attributed to the coupling of the localized QD excited states to the crossed states and scattering of longitudinal acoustical (LA) phonons. The degree of spectral linewidth broadening was larger for the excited state in smaller QDs because of the higher crossed joint density of states and scattering rate.

The photovoltaic performance and charge recombination characteristics of porphyrin-based dye-sensitized solar cell (DSC) devices have been investigated using the impedance spectroscopy (IS) technique. The IS results provide key information related to the device performance for a highly efficient porphyrin dye (YD2), a reference porphyrin dye (YD0), and a commercial ruthenium dye (N719). The DSC devices constructed using YD2 and N719 dyes reach similar internal power conversion efficiencies (7.41% vs 7.54%) due to the higher injection of the YD2 dye that is compromised by a lower photovoltage. In addition, both YD2 and N719 dyes exhibit the same charge-transfer resistance, indicating that the recombination rates of both dyes are very similar. The diarylamino group plays a key role to repel the triiodide ions from the titania surface so that the charge recombination of YD2 is less significant compared with that of YD0.
COLLAGEN VI PROTECTS AGAINST NEURONAL APOPTOSIS ELICITED BY ULTRAVIOLET IRRADIATION VIA AN AKT/PHOSPHATIDYLINOSITOL 3-KINASE SIGNALING PATHWAY

Collagen VI, one of the extracellular matrix proteins, has been implicated in regulating cell proliferation and reducing apoptosis in several different systems. However, the role of collagen VI in the central nervous system remains unclear. In this manuscript, we demonstrated that upon ultraviolet (UV) irradiation, mouse primary hippocampal neurons specifically up-regulate the expression of Col6a1, Col6a2, and Col6a3 mRNA and secreted collagen VI protein. Augmentation of collagen VI mRNA and protein after UV irradiation may have a neuroprotective role as suggested by the fact that extracellular supplying soluble collagen VI protein, but not other collagen proteins, reduced UV induced DNA damage, mitochondria dysfunction, and neurite shrinkage. We also tried to determine the signaling molecules that mediate the protective effect of collagen VI via Western blot and inhibitor analysis. After collagen VI treatment, UV irradiated neurons increased phosphorylation of Akt and decreased phosphorylation of JNK. Inhibiting Akt/Phosphatidylinositol 3-kinases (PI3K) pathway diminished the protective effect of collagen VI. Our study suggested a potential protective mechanism by which neurons up-regulate collagen VI production under stress conditions to activate Akt/PI3K anti-apoptotic signaling pathway. (C) 2011 IBRO.

PALM PAD DEVICE FOR BASKETBALL TRAINING AND BASKETBALL TRAINING SYSTEM
(2011-06-02)
Chen Chung-Chiang
A palm pad device, for use as a training device and to be fastened to the palm of a user, includes a segregate pad having a size-adjustable elastic pad and a fastening member for fastening the segregate pad onto the palm. The palm pad device further includes a sensing recorder disposed on the fastening member for sensing and recording movement data of the palm. The elastic pad includes a thickness pad and a width pad for allowing adjustments in the thickness and width of the segregate pad. A basketball training system using the palm pad device includes a basket sensor for recording the status of successful shots, a sensing recorder disposed on the palm pad device, and a central management apparatus for receiving data transmitted from the sensing recorder and the basket sensor for conducting analysis to thereby generate a corresponding feedback event.

看著書架上林林總總的分類，為什麼總要分成這麼多不同的書目，而不是只有「好書」、「小說」、「暢銷書」等標籤呢？就連幻想小說，都有數不清的分類細目，讓人想一探究竟。

常常可以看見刊登愛犬走失的尋狗啟事，假如那些主人能夠為愛犬施打晶片，對於找回愛犬一定有相當大的幫助。台灣是全世界唯一強制注射動物晶片的國家，但在動物保護法嚴格實施後，卻不見流浪狗問題有明顯改善。除了政府取締開罰態度鬆散，是否因為許多人對寵物晶片的了解仍然相當陌生呢?

閱讀時，往往認為作家和讀者距離遙遠，見其文而不見其人，只能在特定的活動場合才能有所互動。然而，作家並非遠在天邊、遙不可及，想當作家也不是難事，只要透過一些管道，就能抒發情感，或針砭時事。
