Amorphous molybdenum sulfide (MoSx) materials have been considered as cheap and promising catalysts for hydrogen evolution reaction (HER). In this contribution, we report that the amorphous MoSx catalysts prepared by the low temperature thermolysis of the (NH4)(2)MoS4 precursors on carbon clothes (catalyst loading: 3.2 mg/cm(2)) exhibit a Tefal slope of 50.5 mV/dec and a high exchange current density of 1.5 x 10(-3) mA/cm(2) in 0.5 M H2SO4 solutions. Spectroscopic studies of the amorphous MoSx catalysts show that the increase of HER efficiency is positively correlated to the concentration of S-2(2-) species, providing strong evidence to support the argument that S-2(2-) is an active species for electrocatalytic HER. Additionally, the method for preparing catalysts is simple, scalable and applicable for large-scale production. Copyright (C) 2014, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.

A scene imaging method using a portable two-camera omni-imaging device for human-reachable environments is disclosed. Firstly, an upper omni-image and a lower omni-image of at least one scene are captured. Next, image inpainting and image dehazing perform on the upper omni-image and the lower omni-image. Next, image unwrapping performs on the upper omni-image and the lower omni-image by a pano-mapping table, so as to form an upper panoramic image and a lower panoramic image respectively, and the upper panoramic image and the lower panoramic image respectively have an upper part and a lower part overlapping each other. Finally, a data item on the upper part and the lower part is obtained by view points of the scene and the pano-mapping table, thereby stitching the upper and lower panoramic images.

We develop analytic tools for the asymptotics of general trie statistics, which are particularly advantageous for clarifying the asymptotic variance. Many concrete examples are discussed for which new Fourier expansions are given. The tools are also useful for other splitting processes with an underlying binomial distribution. We specially highlight Philippe Flajolet's contribution in the analysis of these random structures. (C) 2014 Elsevier B.V. All rights reserved.
DISSOLUBLE PDMS-MODIFIED p(HEMA-MAA) AMPHIPHILIC COPOLYMER AND METHOD FOR FABRICATING THE SAME

The present invention discloses a dissoluble PDMS-modified p(HEMA-MAA) amphiphilic copolymer and the method of fabricating the same. The amphiphilic copolymer of the present invention is fabricated via chemically bonding HEMA, MAA, and poly(dimethylsiloxane), bis (3-aminopropyl) terminated (PDMS) in aqueous solution. The PDMS-modified p(HEMA-MAA) amphiphilic copolymer can be dissolved completely in polar solvents, particularly alcohol solvents, to facilitate subsequent processing. The amphiphilic copolymer features adjustable hydrophobic-hydrophilic properties and exhibits excellent biocompatibility. Thus, it can be utilized in a number of advanced applications, including anti-fouling and drug delivery.
FREQUENCY MULTIPLIER APPARATUS AND OPERATING METHOD THEREOF

The present invention provides a frequency multiplier apparatus. The frequency multiplier apparatus includes an injection-locked frequency multiplier and a frequency-to-control signal converter. The injection-locked frequency multiplier outputs an output signal having a first frequency in response to an input signal having a first basic frequency. The frequency-to-control signal converter provides a first control signal to the injection-locked frequency multiplier in response to the input signal. The injection-locked frequency multiplier adjusts the first frequency to a second frequency in response to a change of the first control signal when the first basic frequency is changed to a second basic frequency.

剛毅的臉龐，充滿威嚴的眼神，但笑起來卻是十分的和藹，說話的語氣溫和、語調平穩，卻帶著不容置喙的氣勢。當被問到為什麼不教女兒客語時「因為沒有那個環境，就算教她們也是記不住。」朱肇琳只簡單得這麼說，對他來說語言的實用性是最重要的，即使是母語，如果學了卻不能用，那也沒有意義。
