The antenna subtraction method for the computation of higher order corrections to jet observables and exclusive cross sections at collider experiments is extended to include hadronic initial states. In addition to the already known antenna subtraction with both radiators in the final state (final-final antennae), we introduce antenna subtractions with one or two radiators in the initial state (...

We derive QED radiators for the universal corrections to polarized electron scattering. To 5th order in the coupling constant the flavor non-singlet and singlet contributions are calculated. We derive the non-singlet and singlet exponentiation of the leading terms ∝ (α ln(x))k to all orders. Contribution to DIS 2002, April 2002, Cracow.

The saprophytic bacterium Serratia plymuthica was recovered from a facial wound (burn) site of a pediatric patient. The clinical significance of the organism was undetermined due to its apparent eradication from this location by therapy with topical 1% silver sulfadiazine. Seeding of the burn with S. plymuthica may have occurred from contaminated moisture sometimes found on and around steam rad...

We calculate the universal flavor-singlet radiative QED corrections to unpolarized lepton scattering applicable to general differential scattering cross sections, involving charged fermions or photons in initial or final states. The radiators are derived to O((α ln(Q/mf )) 5) in analytic form. Numerical illustrations are given.

We present the electron/pion identification performance measured with prototypes for ALICE TRD. Measured spectra of energy deposit of pions and electrons as well as their average values are presented and compared to calculations. Various radiators are investigated over the momentum range of 1 to 6 GeV/c. The time signature of TR is exploited in a bidimensional likelihood mothod.

Abstract Increase in total heat output of panel radiators could play an important role domestic energy saving, where convectors (convection fins) a key role. Hence, it is to obtain the best possible design convectors, order increase radiators. In this sense, numerical study has been performed show effects different geometrical dimensions on transfer used radiators, highest output. Firstly, simu...
