「如果一個子彈應該進入我的大腦，讓這顆子彈摧毀每一個衣櫃門。」美國首位以公開同性戀身分當選舊金山監督委員的哈維．米爾克，在被槍殺前為同性戀的未來留下了這樣的期許。電影《自由大道》就是描述著哈維．米爾克為美國同性戀者爭取政治上的權利，與當時保守派對抗的勵志故事。

This study presents a novel crosswise ridge micromixer (CRM) with a series of microstructures placed on the top and bottom floors of channels. Passive micromixers fabricated by Micro Electro-Mechanical Systems (MEMS) technologies with slanted ridges are investigated. Numerical simulations and experimental investigations are undertaken to determine the effects of various microstructure patterns on mixing efficiency with Reynolds numbers (Re) of 0.05-50. The confocal images at the cross-sections along the channel with ridges on both the channel top and bottom are first investigated in our study. A significant amount of split and recombination (SAR) helical flows is produced by the slanted ridges embedded on the two floors of the channels. The effects of non-dimensional parameters, such as the Re, as well as geometrical parameters on mixing performance are presented in terms of the mixing index. When the Re exceeds 1, the mixing index of the micromixer with slanted ridges increases as the Re increases further. Simulation results are presented and compared with experimental data. The trends of the experimental results and numerical data are very similar. Finally, various numbers of slanted ridges in the same orientation in one channel cycle are investigated to determine mixing performance in microchannels. The mixing performance achieves an optimum value in case where the number of ridges per cycle is equal to 8. (C) 2011 Elsevier Ltd. All rights reserved.
Optical characterization of isoelectronic ZnSe(1-x)O(x) semiconductors

We have studied the temperature dependence of the band gap and the decay dynamics of isoelectronic ZnSe(1-x)O(x) (x=0-0.053) semiconductors, using photoluminescence (PL) and time-resolved PL spectroscopy. The temperature dependence of the band gap of ZnSe(1-x)O(x) decreases with the increase in 0 concentration. The Kohlrausch law is in good agreement with the O-induced complex decay profiles. As temperature increases, the mechanism of carrier decay undergoes a complicated change from trapped to free excitons. These findings are consistent with the temperature dependence of the stretching exponent beta. (C) 2010 Elsevier B.V. All rights reserved.

今年三月，台灣法務部部長曾勇夫簽下死刑執行令，在五號晚間六點半槍決五名死囚。其中管鐘演、王國華和莊天祝三人同意器官捐贈，死刑犯的器官遺愛人間，總共救了20 人，但這樣的行為卻讓台灣受到國際人權聯盟的撻伐。

Achievement of low interfacial densities of states, small equivalent oxide thickness, high kappa values, and thermal stability at high temperatures in the high kappa dielectrics on high carrier mobility semiconductors, the leading candidates for technology beyond Si CMOS, has been made using MBE. This paper reviews our recent advances in meeting the unprecedented demands in materials and physics for the new technology. Moreover, self-aligned inversion-channel InGaAs and Ge MOSFETs using MBE-Ga(2)O(3)(Gd(2)O(3)) as the gate dielectric are compared favorably with those using the gate dielectrics made from other thin film techniques.

This study examines a procedure developed for planning a nation-wide hazardous campus waste (HCW) collection system. Alternative HCW plans were designed for different collection frequencies, truckloads, storage limits, and also for establishing an additional transfer station. Two clustering methods were applied to group adjacent campuses into clusters based on their locations, HCW quantities, the type of vehicles used and collection frequencies. Transportation risk, storage risk, and collection cost are the major criteria used to evaluate the feasibility of each alternative. Transportation risk is determined based on the accident rates for each road type and collection distance, while storage risk is calculated by estimating the annual average HCW quantity stored on campus. Alternatives with large trucks can reduce both transportation risk and collection cost, but their storage risks would be significantly increased. Alternatives that collect neighboring campuses simultaneously can effectively reduce storage risks as well as collection cost if the minimum quantity to collect for each group of neighboring campuses can be properly set. The three transfer station alternatives evaluated for northern Taiwan are cost effective and involve significantly lower transportation risk. The procedure proposed is expected to facilitate decision making and to support analyses for formulating a proper nation-wide HCW collection plan. (C) 2011 Elsevier B.V. All rights reserved.

We have analyzed threshold gains and lasing modes in GaN-based photonic crystal (PC) surface emitting lasers (PCSELs) by using the multiple scattering method (MSM) for triangular-lattice PC patterns. Moreover, GaN-based PCSELs with different boundary shapes have been fabricated and measured. The lasing mode at the G band edge of GaN-based PCSELs can be identified by using the angled resolved spectroscopy and matched well to the results calculated by MSM. Threshold conditions in the GaN-based PCSELs with different boundary shapes are obtained by optical pumping and agree well with simulation results. (C) 2011 Optical Society of America

The sigma(+) and sigma(-) circularly polarized time-integrated and time-resolved Photoluminescence (PL) measurements were employed to investigate the carrier spin dynamics of ZnMnTe/ZnSe Quantum Dots (QDs) grown on GaAs substrates by molecular beam epitaxy. The Kohlrausch's stretching exponential function well correlates both the sigma(+) and sigma(-) decay profiles. The measured spin relaxation time is about 23 ns. (C) 2010 Elsevier B.V.

The light-emitting diode (LED) with a single GaSb QD layer embedded in a GaAs n-i-p structure operated under different injection currents and temperatures is investigated. With increase in injection currents, room-temperature electroluminescence (EL) peak blue shift is observed until a saturation of EL intensity is reached. In the temperature-varying EL measurements, with increase in temperatures. EL peak blue shift and then red shift are observed, which is attributed to the enhanced luminescence of the smaller QDs with increase in temperatures lower than 100 K. The understanding of the operation mechanisms for the device is advantageous for the practical application of type-II LEDs. (C) 2010 Elsevier B.V. All rights reserved.

他所受的折磨有誰懂？或是說，他們受的苦有誰真的能夠理解？這也是這幾年來，我不斷反問自己的問題。我不懂，我要如何建構自己的信念？我無法體會那種痛，要如何說服便別人？我沒有最寬敞的心胸，又憑什麼認為死刑不合理？
