Dynamics of cavitation bubbles near granular boundaries

Mohamed Farhat, Davide Bernardo Preso, Armand Baptiste Sieber

We study the dynamics of a cavitation bubble near beds of sand of different grain sizes. We use high-speed imaging to observe the motion of the bubble and the sand for different values of the stand-off parameter gamma (dimensionless bubble-boundary distanc ...

Observation of D-0 -> rho(0)gamma and Search for CP Violation in Radiative Charm Decays

Mingkui Wang, Olivier Schneider, Chao Wang, Yiming Li, Sun Hee Kim, Tara Nanut, Jun Yong Kim

We report the first observation of the radiative charm decay D-0 -> rho(0)gamma and the first search for CP violation in decays D-0 -> rho(0)gamma, phi gamma, and (K) over bar (*0)(892)gamma, using a data sample of 943 fb(-1) collected with the Belle detec ...

Study of pi(0) pair production in single-tag two-photon collisions

Mingkui Wang, Olivier Schneider, Chao Wang, Yiming Li, Sun Hee Kim, Tara Nanut, Jun Yong Kim

We report a measurement of the differential cross section of pi(0) pair production in single-tag two-photon collisions, gamma*gamma -> pi(0) pi(0), in e(+) e(-) scattering. The cross section is measured for Q(2) up to 30 GeV2, where Q(2) is the negative of ...

Measurement of the ratio of branching fractions B(B-0 -> K0 gamma)/B(B-s(0) -> phi gamma) and the direct CP asymmetry in B-0 -> K0 gamma

Jian Wang, Olivier Schneider, Yiming Li, Yi Zhang, Lei Zhang, Aurelio Bay, Guido Haefeli, Jessica Prisciandaro, Tatsuya Nakada, Christoph Frei, Mark Tobin, Frédéric Blanc, Minh Tâm Tran, Michel De Cian, Greig Alan Cowan, Maurizio Martinelli, Vladislav Balagura, Donal Patrick Hill, Jean Wicht, Ilya Komarov, Plamen Hristov Hopchev, Bastien Luca Muster, Frédéric Guillaume Dupertuis, Julien Rouvinet, Christophe Salzmann, Pierre Jaton, Barinjaka Rakotomiaramanana, Joël Bressieux, Songmei Wu, Raluca Anca Muresan, Johan Luisier, Albert Puig Navarro, Anne Keune, Vincent Fave, Christophe Bauer, Mathias Oleg Knecht

The ratio of branching fractions of the radiative B decays B-0 -> K-*0 gamma and B-s(0) -> phi gamma has been measured using an integrated luminosity of 1.0 fb(-1) of pp collision data collected by the LHCb experiment at a centre-of-mass energy of root s = ...

Measurement of gamma gamma* -> pi(0) transition form factor at Belle

Olivier Schneider, Chao Wang, Yiming Li, Jun Yong Kim, Remi Léandre Albert Louvot

We report a measurement of the process gamma gamma* -> pi(0) with a 759 fb(-1) data sample recorded with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The pion transition form factor, F(Q(2)), is measured for the kinematical region 4 ...

Left-inverses of fractional Laplacian and sparse stochastic processes

Michaël Unser

The fractional Laplacian (-Delta)(gamma/2) commutes with the primary coordination transformations in the Euclidean space Rd: dilation, translation and rotation, and has tight link to splines, fractals and stable Levy processes. For 0 < gamma < d, its inver ...

First observation of radiative B0 -> phi K0 gamma decays and measurements of their time-dependent CP violation

Olivier Schneider, Yiming Li, Sun Hee Kim, Jun Yong Kim, Remi Léandre Albert Louvot

We report the first observation of the radiative decay B-0 -> phi K-0 gamma using a 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 asymmetric-energy e(+)e(-) collider. We observe a s ...

Green-Ampt approximations

David Andrew Barry

The solution to the Green and Ampt infiltration equation is expressible in terms of the Lambert W-1 function. Approximations for Green and Ampt infiltration are thus derivable from approximations for the W-1 function and vice versa. An infinite family of a ...

Impact of Interferences on Connectivity in Ad Hoc Networks

Patrick Thiran, Olivier Dousse

We study the impact of interferences on the connectivity of large-scale ad-hoc networks, using percolation theory. We assume that a bi-directional connection can be set up between two nodes if the signal to noise ratio at the receiver is larger than some t ...
