Mitigation of collapses of structural systems caused by a strong earthquake shaking is crucial to reduce the potential casualties, injuries and economic losses. Hence, accurate risk assessment of structural collapse under seismic excitations is critical in efforts to promote hazard-resilience of the society. This paper summarizes the authors’ recent efforts for accurate prediction of structural...

We review some recent theoretical progress in the understanding of weak radiative B meson decay, and discuss the implications of present and improved measurements of b → sγ for supersymmetric models. Talk presented at Beauty ’97, Fifth International Workshop on B-Physics at Hadron Machines, Los Angeles, CA, October 13-17, 1997. To be published in Nuclear Instruments and Methods in Physics Resea...

We report results on fB and semi-leptonic B decay form factors using NRQCD. We investigate 1/M scaling behavior of decay amplitudes. For fB Effect of higher order relativistic correction terms are also studied.

Different from the direct contact in epidemics spread, overload failures propagate through hidden functional dependencies. Many studies focused on the critical conditions and catastrophic consequences of cascading failures. However, to understand the network vulnerability and mitigate the cascading overload failures, the knowledge of how the failures propagate in time and space is essential but...

We review recent experimental results on hadronic decays and lifetimes of hadrons containing b and c quarks[1]. We discuss charm counting and the semileptonic branching fraction in B decays, the color suppressed amplitude in B decay, and the search for gluonic penguins in B decay. A complete picture of inclusive B decay is beginning to emerge from recent measurements by CLEO II and the LEP expe...

INTRODUCTION This study aimed to investigate the occurrence of Africanized honeybees in Botucatu, São Paulo, Brazil, and to implement a program to remove such swarms. METHODS The occurrences of Africanized honeybee swarms between 2010 and 2012 were studied and strategies to prevent accidents were developed. RESULTS We noted 1,164 cases of Africanized honeybee occurrences in the city, and 42...

A selection of recent heavyavor results from OPAL using the LEP1 data sample are presented. The average polarization of b baryons in hadronic Z decay has been measured to be 0:56 0:13(stat:) 0:09(syst:) using semileptonic decays of b baryons. A search has been conducted for the radially excited D 0 and has produced a 95% CL upper limit on its production of f(Z ! D 0 (2629)) Br(D 0 ! D + ) < 2:1...
