Calculations of the nuclear modification factor, R dAu , for π 0 production in dAu collisions at √ s N N = 200 GeV are presented. The applied pQCD-improved parton model incorporates intrinsic k T. Nuclear multiscattering and nuclear shadowing are considered in the Au nucleus. Theoretical results are displayed for midrapidity and high pseudorapidity, η, and compared to preliminary PHENIX and BRA...

We propose an original method for determining suitable refracting profiles between two media to solve two related problems: to produce a given wave front from a single point source after refraction at the refracting profile, and to focus a given wave front in a fixed point. These profiles are obtained as envelopes of specific families of Cartesian ovals. We study the singularities of these prof...

We present an integrated 2:1 multiplexer and a companion 1:2 demultiplexer in CMOS. Both integrated circuits (ICs) operate up to a bit rate of 40 Gb/s. The 2:1 multiplexer features two in-phase data inputs which are achieved by a master–slave flip-flop and a master–slave–master flip-flop. Current-mode logic is used because of the higher speed compared to static CMOS and the robustness against c...

In the title compound, C22H18N8 H2O, the dihedral angle between the tetrazole rings is 69.58 (1) while the terminal phenyl ring makes dihedral angles of 26.98 (8) and 39.75 (8) with the other benzene rings. The rings of the biphenyl unit subtend a dihedral angle of 55.23 (8) . In the crystal, the solvent water molecule is linked to the main molecule via an N—H O hydrogen bond. In addition, C—H ...

We report Zeeman infra-red spectroscopy of electronic-nuclear levels 5I8 →5I7 transitions Ho3+ in the C4v(F−) centre CaF2 with magnetic field along ⟨111⟩ direction crystal. Transitions to lowest 5I7 state, an isolated electronic doublet, and next group states, a pseudo-quadruplet consisting doublet two nearby singlets, exhibit strongly non-linear splittings intensity variations. Simulated spect...

This set of lectures provides an overview of the basic theory and phenomenol-ogy of the cosmic microwave background. Topics include a brief historical review; the physics of temperature and polarization fluctuations; acoustic oscillations of the primordial plasma; the space of inflationary cosmological models; current and potential constraints on these models from the microwave background; and ...

Calculations of the nuclear modification factor, R dAu , for π 0 production in dAu collisions at √ s = 200 AGeV are presented. The applied pQCD-improved parton model incorporates intrinsic k T. Nuclear multiscattering and nuclear shadowing are considered in the Au nucleus. Theoretical results are displayed for midrapidity and high pseudorapidity (η), and compared to preliminary PHENIX and BRAHM...
