3782   Validation of the JEFF3.1.1 library for the calculation of the physical measurements in the N4 Chooz-B1 PWR using the continuous energy Monte Carlo code tripoli-4 Validation of the JEFF3.1.1 library for the calculation of the physical measurements in the N4 Chooz-B1 PWR using the continuous energy Monte Carlo code tripoli-4    2010 Since the release of the JEF-2 European File in 1992, constant improvement of this library has been ongoing. The incremental method sustained by the CEA allowed new evaluations only if JEF-2 nuclear data were found in disagreement with differential measurements and if calculation/measurement biases in targeted integral experiments were unacceptable. The release of JEFF-3.1.1 in 2008 [1] benefits from the feedback of experimental validation from critical facilities and fast breeder reactors, as w... 查看全文

3787   Anodic Coupling Reactions and the Synthesis of C-Glycosides Anodic Coupling Reactions and the Synthesis of C-Glycosides Guoxi Xu and Kevin D. Moeller*    2010 A convenient, two-step procedure has been developed for converting sugar derivatives into C-glycosides containing a masked aldehyde functional group. The chemistry takes advantage of an anodic coupling reaction between an electron-rich olefin and an alcohol. The sequence works for the formation of both furanose and pyranose derivatives if less polarized vinyl sulfide derived radical cation intermediates are used. With more polarized enol ether derived radical cations, the cyclizations work best ... 查看全文

3788   Completeness and cut-elimination in the intuitionistic theory of types - Part 2 Completeness and cut-elimination in the intuitionistic theory of types - Part 2    2010 A study was conducted to extend the results of theorem 3 in some new proof-theoretic tools and modify an erroneous construction in one of the cases of the proof of the main theorem. It also established some new correlations between formal properties of the sequent calculus of the intuitionistic theory of types and tableaux. A key technical lemma for proving completeness in the theorem relied on a tableau-style. definition of consistency of a Hintikka set of signed forcing statements in type theo... 查看全文

3789   Generalizing Glycosylation:  Synthesis of the Blood Group Antigens Lea, Leb, and Lex Using a Standard Set of Reaction Conditions Generalizing Glycosylation:  Synthesis of the Blood Group Antigens Lea, Leb, and Lex Using a Standard Set of Reaction Conditions Lin Yan and Daniel Kahne*    1996 Because there are no general reaction conditions for any glycosylation method, biologically interesting oligosaccharides can only be made in a small number of laboratories in the world. To make carbohydrate synthesis accessible to nonspecialists, it is critical to have glycosylation methods that will work in a wide range of cases under a single set of conditions. The Lewis blood group antigens have attracted the attention of numerous synthetic carbohydrate groups because of their structural comp... 查看全文

3790   New regularization procedure as an appropriate algorithm for the evaluation of Langmuir-probe and Thomson scattering measurements New regularization procedure as an appropriate algorithm for the evaluation of Langmuir-probe and Thomson scattering measurements    1994 New mathematical algorithms are presented to evaluate the electron velocity distribution function from Langmuir-probe and Thomson scattering measurements. They are based on the Tikhonov regularization method which is applied to the volt-ampere characteristics of the probe and to the spectral intensity of the scattered light. These methods permit the problem to be formulated as regularized integral equations rather than evaluating the electron velocity distribution function by the usual inadequat... 查看全文

3799   Lecturer,Department of Information Lecturer,Department of Information D. Jeyabharathi    0 In this new millennium most of the transactions depend on wireless network. In this context highly secured transaction of information is the need of the hour. During the transaction there must not be any loss of information or there should be no intrusion to assure the secured data transmission. There are several approaches available for fixed network threats. But it is difficult to analyze the intrusion attacks in mobile networks due to its high mobile nature. In this present work we implemente... 查看全文

3801   Heparin potentiates the in Vivo ectopic bone formation induced by bone morphogenetic protein-2 Heparin potentiates the in Vivo ectopic bone formation induced by bone morphogenetic protein-2    2006 Although bone morphogenetic proteins (BMPs) are clinically useful for bone regeneration, large amounts are required to induce new bone formation in monkeys and humans. We found recently that heparin stimulates BMP activity in vitro (Takada, T., Katagiri, T., Ifuku, M., Morimura, N., Kobayashi, M., Hasegawa, K., Ogamo, A., and Kamijo, R. (2003) J. Biol. Chem. 278, 43229-43235). In the present study, we examined whether heparin enhances bone formation induced by BMPs in vivo and attempted to deter... 查看全文

3802   New general solutions to the Abel equation of the second kind using functional transformations New general solutions to the Abel equation of the second kind using functional transformations    2012 A new method for solving the Abel equation of the second kind yy′=F1(x)y+F0(x) using functional transformations of the form. y=f(ξ(z(x))) is presented. It is important to say that the method depends on the possibility of finding ξ. The method is illustrated for the cases f(ξ)=aξ12 and f(ξ)= eaξ. Finally, the case F(ξ)=ξ, where the necessity and difficulty of finding ξ becomes explicit, is analyzed. © 2011 Elsevier Inc. All rights reserved. 查看全文

3803   The relationship among the solutions of two auxiliary ordinary differential equations The relationship among the solutions of two auxiliary ordinary differential equations    2009 In a recent article [Phys. Lett. A 356 (2006) 124], Sirendaoreji extended their auxiliary equation method by introducing a new auxiliary ordinary differential equation (NAODE) and its 14 solutions. Then the author studied some nonlinear evolution equations (NLEEs) and got more exact travelling wave solutions. In this paper, we will show that the 14 solutions of the NAODE are actually the same as the solutions obtained by original auxiliary equation method, and they are only different in the form... 查看全文

3805   Poverty, Innovation Capacity, and State Economic Development in the Knowledge Economy: Evidence from the U.S. Poverty, Innovation Capacity, and State Economic Development in the Knowledge Economy: Evidence from the U.S. Philip L. Smith    2012 We examine poverty's effect in two ways. First, we study the relationship between poverty and capacity for innovation in the U.S. states; second, we study the combined effects of poverty and innovation capacity on U.S. state economic output and employment. Because many of the relationships among poverty, innovation capacity and economic performance are simultaneous, we employ the Arellano Bond Difference GMM estimator to estimate various models using panel data (1980–1999). The findings re... 查看全文

3806   Preferential Binding of Human Full-Length XPA and the Minimal DNA Binding Domain (XPA-MF122) with the Mitomycin C−DNA Interstrand Cross-Link† Preferential Binding of Human Full-Length XPA and the Minimal DNA Binding Domain (XPA-MF122) with the Mitomycin C−DNA Interstrand Cross-Link† David J. Mustra,‡ Amy J. Warren,‡ and Joshua W. Hamilton*‡§    2001 Nucleotide excision repair (NER) is an important cellular mechanism that removes radiation-induced and chemically induced damage from DNA. The XPA protein is involved in the damage recognition step of NER and appears to function by binding damaged DNA and recruiting other proteins to the site. It may also play a role in subsequent steps of NER through interaction with other repair proteins. Interstrand cross-links are of particular interest, since these lesions involve both strands of duplex DNA... 查看全文
