We discuss microscopic cluster model descriptions of two solar nuclear reactions , 7 Be(p, γ) 8 B and 3 He(3 He, 2p) 4 He. The low-energy reaction cross section of 7 Be(p, γ) 8 B, which determines the high-energy solar neutrino flux, is constrained by 7 Be and 8 B observables. Our results show that a small value of the zero-energy cross section is rather unlikely. In 3 He(3 He, 2p) 4 He we stud...

The measurement of the inclusive jet cross section at the Tevatron is an important test of perturbative QCD (pQCD) predictions over more than 8 orders of magnitude, probing distances down to 10m. The increased center-of-mass energy in Run II (from 1.8 TeV to 1.96 TeV), the highly upgraded CDF detector1, and the amount of data collected allow jet measurements in an extended region of jet transve...

We study neutrino induced one-pion production off the nucleon in and around the Delta resonance region. Apart from the Delta-pole mechanism we include background terms required by chiral symmetry. These background terms give sizeable contributions in all channels. To better reproduce the ANL q-differential cross section data, we make a new fit of the C 5 (q ) axial nucleon to Delta form factor....

This paper deals with MIMO channel modeling according to the correlation level in underground railway tunnels for various antenna configurations for the transmitting and receiving arrays. MIMO channel matrices have been computed with a 3D ray-tracing based software at 2.4 GHz and 5.8 GHz in two different tunnel environments: 1) a 1-track empty tunnel with a square cross section, 2) a 1-track tu...

The top quark was discovered in 1995 by the CDF and D0 collaborations [2, 3]. During Run I (1992-1996) both experiments collected a data set of about 125 pb. In 2001 Run II has started operating with a center-of-mass-energy of √ s = 1.96 TeV and an increased luminosity. One of the main aims is to further investigate the properties of top quarks. End of 2006 there was first evidence for single t...

We study bound states below threshold and resonances above threshold in the DK and D s η systems, using a many-coupled-channel model for nonexotic meson-meson scattering applied to states with the quantum numbers of cs̄ quark-antiquark vector mesons. We fit the ground state at 2.112 GeV, whence the lowest resonances in DK come out at 2.43, 2.61, 2.73, 3.06, and 3.11 GeV. The resonance at 2.61 Ge...

Creation of a transonic region by means gas fuel burning in supersonic flow with Mach number M = 2 channel variable cross section is studied numerically. The averaged Navier – Stokes equations closed the k-ε model turbulence are solved. created using gas-dynamic pulses throttling jet, which initiates gaseous combustion constant section. (ethylene or kerosene) supplied axially into axisymmetric ...

We report and demonstrate a new method to fabricate single fluidic-channels of uniform channel width (11-50 nm) and over 1.5 cm in length, which are essential to developing innovative bio/chemical sensors but have not been fabricated previously. The method uses unconventional nanofabrication (a combination of crystallographic anisotropic etching, conformal coating, and edge patterning, etc.) to...
