The authors present updated measurements of the branching fractions for the modes B{sup 0} --> {pi}{sup 0}{pi}{sup 0}, B{sup {+-}} --> {pi}{sup {+-}}{pi}{sup 0}, and B{sup {+-}} --> K{sup {+-}}{pi}{sup 0}. They also measure the time-integrated asymmetry C{sub {pi}}{sup 0}{pi}{sup 0} and the charge asymmetries A{sub {pi}}{sup {+-}}{pi}{sup 0} and A{sub K}{sup {+-}}{pi}{sup 0}.

We present preliminary results of searches for exclusive B[sup 0] decays to[pi][sup+][pi][sup -][pi][sup 0] among 22.7 million b[bar b] pairs collected by the BABAR experiment from electron-positron collisions near the[Upsilon](4S) resonance. We measure[Beta](B[sup 0][yields][pi][sup[+-]])= (28.9[+-] 5.4[+-] 4.3) x 10[sup 6], and find no evidence for the presence of any other decay mode in the[pi][sup+][pi][sup -][pi][sup 0] Dalitz plot. Upper limits are determined for the branching fractions of B[sup 0][yields][sup 0][pi][sup 0], non-resonant B[sup 0] decays to[pi][sup+][pi][sup -][pi][sup 0] and of several discrete regions of[pi][sup+][pi][sup -][pi][sup 0] phase-space. We also measure the direct CP-violating asymmetry between the rates of untagged[sup+][pi][sup -] and[sup -][pi][sup+], finding no significant evidence for an effect.

We report on analyses of B[sup -] mesons decaying into D*[sup+][pi][sup -][pi][sup -] and D[sup+][pi][sup -][pi][sup -] final states using 89 million B[sup -] decays collected by the BABAR detector at the PEP-II asymmetric-energy B Factory. Preliminary measurements are given for the inclusive branching fractions for B[sup -][yields] D*[sup+][pi][sup -][pi][sup -] and B[sup -][yields] D*[sup+][pi][sup -][pi][sup -], and for the exclusive branching fractions for B[sup -][yields] D[sub 1](2420)[sup 0][pi][sup -] and B[sup -][yields] D*[sub 2](2460)[sup 0][pi][sup -], where D[sub 1](2420)[sup 0] and D*[sub 2](2460)[sup 0] are the two narrow c[bar u] P-wave states. The ratio[Beta](B[sup -][yields] D*[sub 2](2460)[sup 0][pi][sup -])/[Beta](B[sup -][yields] D[sub 1](2420)[sup 0][pi][sup -]) is measured to be 0.80[+-] 0.07[+-] 0.16.

The authors present results for the branching fractions and charge asymmetries in B[sup[+-]][yields] h[sup[+-]][pi][sup 0] (where h[sup[+-]]=[pi][sup[+-]], K[sup[+-]]) and a search for the decay B[sup 0][yields][pi][sup 0][pi][sup 0] using a sample of approximately 88 million B[bar B] pairs collected by the BABAR detector at the PEP-II asymmetric-energy B Factor at SLAC. They measure[Beta](B[sup[+-]][yields][pi][sup[+-]][pi][sup 0])= (5.5[sub -0.9][sup+1.0][+-] 0.6) x 10[sup -6], where the first error is statistical and the second is systematic. The B[sup[+-]][yields][pi][sup[+-]][pi][sup 0] signal has a significance of 7.7[sigma] including systematic uncertainties. The authors simultaneously measure the K[sup[+-]][pi][sup 0] branching fraction to be[Beta](B[sup[+-]][yields] K[sup[+-]][pi][sup 0])= (12.8[sub -1.1][sup+1.2][+-] 1.0) x 10[sup -6]. The charge asymmetries are[Alpha][sub[pi][sup[+-]][pi][sup 0]]= -0.03[sub -0.17][sup+0.18][+-] 0.02 and[Alpha][sub[Kappa][sup[+-]][pi][sup 0]]= -0.09[+-] 0.09[+-] 0.01. The authors place a 90% confidence-level upper limit on the branching fraction[Beta](B[sup 0][yields][pi][sup 0][pi][sup 0]) of 3.6 x 10[sup -6].

Cities And Their Vital Systems written by Advisory Committee on Technology and Society and has been published by National Academies Press this book supported file pdf, txt, epub, kindle and other format this book has been release on 1989 with Social Science categories.

Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.
