Precise Measurement of the CP Violation Parameter sin2 phi(1) in B-0 -> (c(c)over-bar) K-0 Decays

Olivier Schneider, Yiming Li, Aurelio Bay, Mingkui Wang, Chao Wang, Tagir Aushev, Jun Yong Kim, Remi Léandre Albert Louvot, Ji Hyun Kim, Jing Li

We present a precise measurement of the CP violation parameter sin2 phi(1) and the direct CP violation parameter A(f) using the final data sample of 772 x 10(6) B (B) over bar pairs collected at the gamma(4S) resonance with the Belle detector at the KEKB a ...

Experimental study from linear to chaotic regimes on a terahertz-frequency gyrotron oscillator

Stefano Alberti, Minh Quang Tran, Jean-Philippe Ansermet, Jean-Philippe Hogge, Damien Fasel, Jérémie Dubray, Philippe Cuanillon, Alessandro Macor, Miguel Da Silva

Basic wave-particle interaction dynamics from linear to chaotic regimes is experimentally studied on a frequency tunable gyrotron generating THz radiation in continuous mode (200W) at 263GHz which will be used for dynamic nuclear polarization nuclear magne ...

A Multiple Hypothesis Gaussian Mixture Filter for Acoustic Source Localization and Tracking

In this work, we address the problem of tracking an acoustic source based on measured time difference of arrivals (TDOAs). The classical solution to this problem consists in using a detector, which estimates the TDOA for each microphone pair, and then appl ...

Single-top t-channel hadroproduction in the four-flavour scheme with POWHEG and aMC@NLO

Paolo Torrielli

We present results for the QCD next-to-leading order (NLO) calculation of single-top t-channel production in the 4-flavour scheme, interfaced to Parton Shower (PS) Monte Carlo programs according to the POWHEG and MC@NLO methods. Comparisons between the two ...

Vector Control of Single-Phase Voltage-Source Converters Based on Fictive-Axis Emulation

Alfred Rufer, Behrooz Bahrani, Stephan Kenzelmann

This paper presents an alternative way for the current regulation of single-phase voltage-source dc-ac converters in direct-quadrature (dq) synchronous reference frames. In a dq reference frame, ac (time varying) quantities appear as dc (time invariant) on ...

A case study of the effect of grain size on the oxygen permeation flux of BSCF disk-shaped membrane fabricated by thermoplastic processing

Stefan Diethelm

Oxygen permeability measurements of Ba0.5Sr0.5Co0.8Fe0.2O3−δ (BSCF) disk shaped membranes fabricated by thermoplastic processing and sintered at different temperatures (1000–1100 °C), showed no influence of the grain size on the oxygen permeation fluxes. T ...

A stochastic reach-avoid problem with random obstacles

Maryam Kamgarpour, John Lygeros

We present a dynamic programming based solution to a stochastic reachability problem for a controlled discrete-time stochastic hybrid system. A sum-multiplicative cost function is introduced along with a corresponding dynamic recursion which quantifies the ...

A hybrid travel time prediction framework for planned motorway roadworks

In this paper we propose a hybrid motorway travel time prediction framework aimed at providing pre-trip travel information in case of roadworks. The framework utilises a first order macroscopic traffic flow model to predict the consequences in travel time ...

Discontinuous Galerkin method for the spherically reduced Baumgarte-Shapiro-Shibata-Nakamura system with second-order operators

Jan Sickmann Hesthaven

We present a high-order accurate discontinuous Galerkin method for evolving the spherically reduced Baumgarte-Shapiro-Shibata-Nakamura (BSSN) system expressed in terms of second-order spatial operators. Our multidomain method achieves global spectral accur ...

Evidence of time-dependent CP violation in the decay B^{0}→D^{+}D^{-}

Olivier Schneider, Aurelio Bay, Chao Wang, Tagir Aushev, Vladislav Balagura, Jean Wicht, Remi Léandre Albert Louvot, Nicolas Zwahlen, Jing Li

We report a measurement of the CP-odd fraction and the time-dependent CP violation in B-0 -> D*+D*- decays, using 657x10(6) BB events collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We measure ...
