Measurement of branching fraction ratios and CP asymmetries in B ±→D;CPK±

Aurelio Bay, Tagir Aushev, Sun Hee Kim, Ji Hyun Kim, Donghyun Kim, Sanjeev Kumar, Jing Li

We report results on the decay B- → DCPK - and its charge conjugate using a data sample of 85.4 × 106 BB̄ pairs recorded at the γ(4S) resonance with the Belle detector at the KEKB asymmetric e+e- storage ring. Ratios of branching fractions of Cabibbo-suppr ...

Target-space anomalies and elliptic indices in heterotic orbifolds

Claudio Scrucca

We present a complete string theory analysis of all mixed gauge, gravitational and target-space anomalies potentially arising in the simplest heterotic Z(N) orbifold models, with N odd and standard embedding. These anomalies turn out to be encoded in an el ...

Supervised learning of perceptron and output feedback dynamic networks: a feedback analysis via the small gain theorem

Ali H. Sayed

This paper provides a time-domain feedback analysis of the perceptron learning algorithm and of training schemes for dynamic networks with output feedback. It studies the robustness performance of the algorithms in the presence of uncertainties that might ...

A time-domain feedback analysis of filtered-error adaptive gradient algorithms

Ali H. Sayed

This paper provides a time-domain feedback analysis of gradient-based adaptive schemes. A key emphasis is on the robustness performance of the adaptive filters in the presence of disturbances and modeling uncertainties (along the lines of H/sup /spl infin/ ...

A time-domain feedback analysis of adaptive gradient algorithms via the small gain theorem

Ali H. Sayed

This paper provides a time-domain feedback analysis of gradient-based adaptive schemes with emphasis on stability and robustness issues. It is shown that an intrinsic feedback structure, mapping the noise sequence and the initial weight guess to the a prio ...

A Time-Domain Feedback-Analysis of Recursive Identification Schemes

Ali H. Sayed

This paper provides a time-domain feedback analysis of several adaptive schemes with emphasis on stability and robustness issues. It is shown that an intrinsic feedback structure, mapping the noise sequence and the initial weight guess to the apriori estim ...
