  • Branching ratios and C P asymmetries of B -> chi K-c1(pi) decays

    Rui, Zhou   Zhao, Qiang   Zhang, Li-li  

    We investigate the exclusive nonleptonic decays B -> chi K-c1(pi) in the conventional perturbative QCD (PQCD) formalism. The predictions of branching ratios and CP asymmetries are given in detail. We compare our results with available experimental data as well as predictions of other theoretical studies existing in the literature. It seems that the branching ratios of B -> chi K-c1 are more consistent with data than the earlier analyses. For the Cabibbo-suppressed B-s decays, the branching ratios can reach the order of 10(-5), which would be straight forward for experimental observations. The numerical results show that the direct CP asymmetries of the concerned decays are rather small. The mixing induced CP asymmetry in the B-0 -> chi K-c1(S) is very close to sin 2 beta, which suggests that this channel offer an alternative method for measuring the Cabbibo-Kobayashi-Maskawa (CKM) angle beta. The obtained results in the present work could be tested by further experiments in the LHCb and forthcoming Belle II.

  • Local operators on C(p)

    Leung, Denny H.   Wang, Ya-Shu  

    Let X be an open set in a Banach space G on which there is a C(p) bump function with bounded derivatives. We present a complete characterization of local (i.e., support shrinking) linear operators T : C(p) (X, E) -> C(q)(X, F), where E and F are Banach spaces. (C) 2011 Elsevier Inc. All rights reserved.

  • Organizing the complete works of C. P. E. Bach

    Corneilson, P.  

    Carl Philipp Emanuel Bach: The Complete Works, an editorial and publishing project of The Packard Humanities Institute, began planning the critical edition in the late 1990s and published its first volumes in 2005. One of the principal problems of the Edition is how to organize more than a thousand works, ranging from short keyboard pieces and songs to major oratorios, cantatas and Passions. C. P. E. Bach, like most of his contemporaries, frequently borrowed music from himself or other composers and also revised his works for different media. The contents of volumes have changed as new discoveries are made, especially the recovery of the Sing-Akademie archive, which was inaccessible from 1943 until 1999.

  • Growth in the Perception of Cyber Risk: Evidence from U.S. P&C Insurers

    David M. Pooser   Mark J. Browne   Oleksandra Arkhangelska  

    The perception of cyber risk has increased in the economy and especially in insurance firms. Using data from publicly traded U.S. property–casualty (P&C) insurers, we examine the trend in cyber risk identification from 2006 to 2015, as well as firms’ characteristics related to cyber risk perception. Roughly one-quarter of our sample identified cyber risk as a material risk factor in 2006, and this group of our sample grew to include substantially all insurers by 2013. The firms that were “early adopters” of cyber risk identification tend to be the smaller, more highly leveraged and higher growth firms. These firms are also more concentrated in their line of business portfolio and use less external reinsurance. This evidence may suggest that the early identifiers of cyber risk were the most sensitive to potential disruption based on their size or firm risk.

  • Palladium-catalyzed R2(O)P directed C(sp2)–H acetoxylation

    Zhang, Heng   Hu, Rong-Bin   Zhang, Xiao-Yu   Li, Shi-Xia   Yang, Shang-Dong  

    A novel and efficient Pd-catalyzed C-H acetoxylation is described. The approach uses R-2(O)P as a directing group to synthesize various substituted 2'-phosphorylbiphenyl-2-OAc compounds. Notably, the reaction exhibits smooth operation under mild conditions and shows good functional group tolerance. Products are obtained with high selectivity and yields.

  • Methodology for P&C cyber security studies using real-time digital simulation

    Li, Jianing; Yang, Conghuan; Kong, Dechao; Mann, Stuart; Zhang, Xiao-Ping  

    With the smart grid development, advancements in deeply integrated information and communication technology (ICT) provide enhanced system awareness, effective decision-making support and high-performance protection and control (P&C) to improve operational reliably and stability of the modern power systems. To manage the risks relevant to the existing industrial P&C systems, it is of high necessity to develop a methodology of cyber security testing for industrial P&C systems. This methodology will be rolled out to continue to evaluate the risks for the next-generation industrial P&C systems when new ICTs are introduced e.g. IEC 61850. This study summarises the main purpose, scope of work of an innovation project in collaboration with National Grid. This on-going project is to develop such a methodology using the state-of-art real-time digital simulation to conduct hardware-in-the-loop testing.
