Information about the Cabibbo–Kobayashi–Maskawa (CKM) matrix describing the chargechanging weak transitions between quarks with charges −1/3 (d, s, b) and 2/3 (u, c, t) has been steadily improving over the years. Despite a wealth of overconstraining experiments, no significant inconsistencies in its parameters have emerged so far. One seeks greater accuracy in the determination of CKM elements ...

The firing squad synchronization problem has been studied extensively for more than forty years, and a rich variety of synchronization algorithms have been proposed. In the present paper, we give a survey on recent developments in firing squad synchronization algorithms for synchronizing large-scale two-dimensional cellular automata. Several new algorithms and their stateefficient implementatio...

B mixing measurements from the Tevatron Run I data are reported. These include time-integrated measurements of the average mixing parameter χ, six timedependent oscillation measurements of ∆md, and a time-dependent limit on ∆ms. Such measurements provide constraints on CKM matrix elements. A sample of B/B → J/ψK S decays is used to directly measure the CP -violation parameter sin(2β). This valu...

By using a mixture model for the density distribution of the three pseudobond angles formed by Cα atoms of four consecutive residues, the local structural states are discretized as 17 conformational letters of a protein structural alphabet. This coarse-graining procedure converts a 3D structure to a 1D code sequence. A substitution matrix between these letters is constructed based on the struct...

The currently favored model of CP violation is based on phases in the Cabibbo-Kobayashi-Maskawa (CKM) matrix describing the weak charge-changing couplings of quarks. The present status of parameters of this matrix is described. Tests of the theory, with particular emphasis on the study of B meson decays, are then noted. Some remarks are made regarding the possible origin of the baryon asymmetry...

Information about the Cabibbo–Kobayashi–Maskawa (CKM) matrix describing the chargechanging weak transitions between quarks with charges −1/3 (d, s, b) and 2/3 (u, c, t) has been steadily improving over the years. Despite a wealth of experiments which overconstrain the matrix and could lead in the presence of new physics to inconsistencies, none have emerged so far at a statistically significant...

The current status of some methods to determine the weak phase γ of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element V ∗ ub using B decays is discussed, and comments are made on accuracy achievable in the next few years.

Consider a fully connected network where up to t processes may crash, and all processes start in an arbitrary memory state. The self-stabilizing firing squad problem consists of eventually guaranteeing simultaneous response to an external input. This is modeled by requiring that the non-crashed processes “fire” simultaneously if some correct process received an external “go” input, and that the...

Few analytic results exist for the firing-rate dynamics of spatially extended neuron models driven by distributed synaptic input. Using an upcrossing approximation firing rate, statistics spatiotemporal voltage are derived and show that minimal dendritic exhibit unexpectedly sustained high-frequency response.

a two-variable integrate and fire model is presented to study the role of transient outward potassium currents in producing temporal aspects of dorsal cochlear nucleus (dcn) pyramidal cells with different profiles namely the chopper, the pauser and the buildup. this conductance based model is a reduced version of km-lif model (meng & rinzel, 2010) which captures qualitative firing features of a...
