231   Molecular Mechanism for Lipid Flip-Flops Molecular Mechanism for Lipid Flip-Flops
Andrey A. Gurtovenko*† and Ilpo Vattulainen‡§    2007
Transmembrane lipid translocation (flip-flop) processes are involved in a variety of properties and functions of cell membranes, such as membrane asymmetry and programmed cell death. Yet, flip-flops are one of the least understood dynamical processes in membranes. In this work, we elucidate the molecular mechanism of pore-mediated transmembrane lipid translocation (flip-flop) acquired from extensive atomistic molecular dynamics simulations. On the basis of 50 successful flip-flop events resolved...

233   Joint behavior. of point process of exceedances and partial sum from a Gaussian sequence Joint behavior. of point process of exceedances and partial sum from a Gaussian sequence
Aiping Hu, Zuoxiang Peng;Yongcheng Qi    2009
Consider a triangular array of mean zero Gaussian random variables. Under some weak conditions this paper proves that the partial sums and the point processes of exceedances formed by the array are asymptotically independent. For a standardized stationary Gaussian sequence, it is shown under some mild conditions that the point process of exceedances formed by the sequence (after centered at the sample mean) converges in distribution to a Poisson process and it is asymptot...

237   Automatic segmentation of cell nuclei in Feulgen-stained histological sections of prostate cancer and quantitative evaluation of segmentation results Automatic segmentation of cell nuclei in Feulgen-stained histological sections of prostate cancer and quantitative evaluation of segmentation results
Henry D. Nissenbaum    2012
Digital image analysis of cell nuclei is useful to obtain quantitative information for the diagnosis and prognosis of cancer. However, the lack of a reliable automatic nuclear segmentation is a limiting factor for high-throughput nuclear image analysis. We have developed a method for automatic segmentation of nuclei in Feulgen-stained histological sections of prostate cancer. A local adaptive thresholding with an object perimeter gradient verification step detected the nuclei and was combined wi...

239   Motion Artifacts Compensation in FDK Based 3D Cone-beam Tomography Using Correlation of X-ray Projection Motion Artifacts Compensation in FDK Based 3D Cone-beam Tomography Using Correlation of X-ray Projection
Ujjal Kumar Bhowmik, Reza R. Adhami    0
Abstract — Head motion during brain CT studies can adversely affect the reconstructed image through distortion and other artifacts such as blurring and doubling, thereby losing substantial information. In this paper, we propose a method to detect and eliminate motion artifacts in Feldkamp-David-Kress (FDK) based three-dimensional (3D) cone-beam tomography. Motion detection is achieved by comparing the correlation coefficient between the adjacent x-ray projections and elimination is done by repla

243   MOBILE 3D-X-RAY TOMOGRAPHY FOR ANALYSIS OF PLANAR DEFECTS IN WELDS BY “TOMOCAR” MOBILE 3D-X-RAY TOMOGRAPHY FOR ANALYSIS OF PLANAR DEFECTS IN WELDS BY “TOMOCAR”
B. Redmer, U. Ewert, C. Rädel, U. Zscherpel, A. V. Likhatchov, V. V. Pickalov, B. Neundorf    0
Abstract: Tomographical Computer Aided Radiology (TomoCAR) is based on the mechanical position control of an X-ray tube in front of a welding seam and the application of a planar array detector behind it. Several hundred radiometric projections in small angle steps are acquired. The tomographical reconstruction allows the threedimensional (3D) representation of the defects. A new radiometric array detector system with a small internal unsharpness and high image contrast is used for the 2- and 3-...

244   Nitrogen Vacancy-Promoted Photocatalytic Activity of Graphitic Carbon Nitride Nitrogen Vacancy-Promoted Photocatalytic Activity of Graphitic Carbon Nitride
Ping Niu, Gang Liu*, and Hui-Ming Cheng    2012
Vacancy defects can play an important role in modifying the electronic structure and the properties of photoexcited charge carriers and consequently the photocatalytic activity of semiconductor photocatalysts. By controlling the polycondensation temperature of a dicyandiamide precursor in the preparation of graphitic carbon nitride (g-C3N4), we introduced nitrogen vacancies in the framework of g-C3N4. These vacancies exert remarkable effects on modifying the electronic structure of g-C3N4 as sho

245   SOCIAL CONSTRUCTION OF ANANGU DISABILITY SOCIAL CONSTRUCTION OF ANANGU DISABILITY
Xing-Hua Zhou, Jingdong Luo, Su Huang, Tae-Dong Kim, Zhengwei Shi, Yen-Ju Cheng, Sei-Hum Jang, Danie    2002
The usual and common-sense definition of disability is based on a medical model that sees disability as a limitation or lack of competence on the part of the individual. This definition fails to acknowledge that in some cultures disability as a concept does not exist. This paper, based on research undertaken in 1994/1995, examines how the social construction of disability among the Anangu of the cross border region of Western Australia, South Australia and the Northern Territory, takes into cons...

247   Properties of silk fibers modified with diethylene glycol dimethacrylate Properties of silk fibers modified with diethylene glycol dimethacrylate
Xing-Hua Zhou, Jingdong Luo, Su Huang, Tae-Dong Kim, Zhengwei Shi, Yen-Ju Cheng, Sei-Hum Jang, Danie    2006
A self-prepared novel bifunctional vinyl monomer diethylene glycol dimethacrylate (EGDMA-2) was graft copolymerized onto silk fibers initiated by potassium persulfate (KPS). The moisture regain and fiber fineness of grafted silk fibers increased linearly with graft yield. The enhancement of hygroscopicity can improve the comfort of silk fabrics. The grafting conditions caused a partial degradation of the tensile strength of silk fibers, as well as the whiteness. Elongation at break increased and...

248   Swelling-assisted modification of poly(ethylene terephthalate) by methacrylic acid Swelling-assisted modification of poly(ethylene terephthalate) by methacrylic acid
Kalyan Raidongia, K.nbsp;P.nbsp;S.nbsp;S. Hembram, Umeshnbsp;V. Waghmare, M. Eswaramoorthy and C.nbs    2003
When a poly(ethylene terephthalate), PET, film is heated in an aqueous solution of methacrylic acid in the presence of hydrogen peroxide as an initiator, it is found that the weight of the film is increased. The amount of methacrylic acid that may be added onto the film is dependent upon the concentration of the monomer, the initiator, and the temperature at which the reaction occurs. Pretreatment of the film with 1,1,2,2,tetrachloroethane causes swelling and the amount of add-on is increased as...

249   Cheating Cheating Detectors Cheating Cheating Detectors
Christian Collberg, Ginger Myles    2004
In this paper we present a new cheating technique that is successful at defeating cheating detectors and could become popular with students. The idea is to use obfuscating code transformations (such as those found in the SANDMARK tool) to apply a sequence of minor code transformations to a copied programming assignment. This purpose is to produce a copy that will defeat detection. We show that this technique is successful in defeating common plagiarism detectors such as Moss. This paper is offer...

Ruben Jakob    2008
In the present article, the author proves two generalizations of his “finiteness-result” (I.H.P. Anal. Non-lineaire, 2006, accepted) which states for any extreme simple closed polygon G ì \mathbbR3\Gamma \subset {\mathbb{R}}^3 that every immersed, stable disc-type minimal surface spanning Γ is an isolated point of the set of all disc-type minimal surfaces spanning Γ w.r.t. the C 0-topology. First, it is proved that this statement holds true for any ...

Salleh Ibrahim, Chao-Long Chen, Chih-Che Lin, Chin-Hsiang Yang, Chih-Chi Wang, Shih-Ho Wang, Yeuh-We    2012
Full-right-full-left split liver transplantation divides a donor liver into two grafts to be transplanted in adult-size patients. Major technical and organizational difficulties have limited its application to few single center series. We retrospectively analyzed the long-term results of the first multicenter series of this procedure with graft sharing. Between November 1998 and January 2005, 43 transplants were performed by five centers from 23 full-right-full-left in situ split liver procedure...

This chapter contains a brief introduction to first order time-invariant (i.e., constant coefficient) systems of differential equations. The objective is to discuss those systems with symmetries in which an indefinite inner product plays a role, so that these applications serve to fix some of the theory already developed. Also, the scene will be set for a more substantial treatment of higher order systems in Chapter 13. The reader is referred to beginning differential equ...

P. H. B. Bolton-Maggs, R. F. Stevens, N. J. Dodd, G. Lamont, P. Tittensor and M.-J. King, General Ha    2007
ABSTRACT– Many previous studies indicate that the attitudes of the staff towards patients who attempt suicide are often negative. Nevertheless, the attitudes of the staff working in different areas of an emergency department have not been studied. The purpose of this study was to explain the attitudes of emergency personnel (n= 184) towards patients who attempt suicide in the different stages of treatment in a general hospital by comparing the attitudes of the staff in the emergency room (...

Zili Wu, Viviane Schwartz, Meijun Li, Adam Justin Rondinone, and Steve H. Overbury    2012
The support effect has long been an intriguing topic in catalysis research. With the advancement of nanomaterial synthesis, the availability of faceted oxide nanocrystals provides the opportunity to gain unprecedented insights into the support effect by employing these well-structured nanocrystals. In this paper, we show by utilizing ceria nanoshapes as supports for vanadium oxide that the shape of the support poses a profound effect on the catalytic performance of metal oxide catalysts. Specifi...

259   Effect of Surface Geometry on the Photochemical Reaction of 1,10-Phenanthroline Adsorbed on Silver Colloid Surfaces Effect of Surface Geometry on the Photochemical Reaction of 1,10-Phenanthroline Adsorbed on Silver Colloid Surfaces
Nak Han Jang,†‡ Jung Sang Suh,*† and Martin Moskovits*‡    1997
The surface-enhanced Raman scattering spectra and the photochemistry of 1,10-phenanthroline (phen) adsorbed on silver colloid were studied using a flow cell. Phen adsorbed on fresh colloid is found to undergo almost no photochemistry while the same molecule adsorbed on aged colloid appears to photodecompose to a species in which the C?N ring bond in one or both of the heterocycles is broken to produce a CN moiety that binds to the silver surface. The contrast in the behavior. of the two colloids...

260   Hydrosilylation of Styrene on Water-Saturated Si(001)-2×1 at Room Temperature Hydrosilylation of Styrene on Water-Saturated Si(001)-2×1 at Room Temperature
F. Bournel*†, J.-J. Gallet†, D. Pierucci†, A. Khaliq†, F. Rochet†, and A. Pietzsch‡    2011
The Si(001)-2×1 surface saturated by water is characterized by the passivation of nearly all of the dimerized atoms by H/OH terminations, except isolated dangling bonds, whose areal density is in the range of 1.5 ± 0.2 × 10–2 defects per Si atom. Therefore the water-saturated Si(001)-2×1 surface presents similarities with the defective H-terminated Si(001)-2×1 surface (presence of monohydrides and isolated dangling bonds), on which alkene molecules are known to be grafted via a radical-based hyd
