We present the first measurement of pseudorapidity densities primary charged particles near midrapidity in Au+Au collisions at sqrt[s(NN)] = 56 and 130 GeV. For most central collisions, we find charged-particle density to be dN/deta|(|eta|<1) 408+/-12(stat)+/-30(syst) GeV 555+/-12(stat)+/-35(syst) GeV, values that are higher than any previously observed nuclear collisions. Compared proton-antiproton our data show an increase per participant by more 40% energy.
The ATLAS TRT barrel is a tracking drift chamber using 52,544 individual tubular tubes. It one part of the Inner Detector, which consists three sub-systems: pixel detector spanning radius range 4 to 20 cm, semiconductor tracker (SCT) from 30 52 and transition radiation (TRT) 56 108 cm. covers central pseudo-rapidity region |η|< 1, while endcaps cover forward backward eta regions. These systems provide combination continuous with many measurements in tubes (or straws) electron identification...
Abstract The purpose of this paper is to provide general information about basic physical processes involved in organic electroluminescence and present the main parameters advantages light emitting devices (OLEDs).
Abstract Machine learning (ML) techniques are emerging as transformative tools for field development planning by offering rapid and accurate predictions of the subsurface. Hybrid conventional-ML workflows enable engineers to swiftly systematically screen optimum solutions in nearly infinite design space. To evaluate their effectiveness, this paper presents an end-to-end case study where Fourier neural operators (FNOs) employed within a CO2 well placement workflow. The workflow combines data...
The ATLAS TRT end-cap is a tracking drift chamber using 245,760 individual tubular tubes. It part of the tracker which consist barrel and two end-caps. end-caps cover forward backward pseudo-rapidity region 1.0 < |η| 2.0, while central η 1.0. system provides combination continuous with many measurements in tubes (or straws) electron identification based on transition radiation from fibers or foils interleaved between straws themselves.

Abstract The paper presents an overview of the design status Radial Neutron Camera (RNC), that, together with Vertical Camera, will provide, through reconstruction techniques applied to measured line-integrated neutron fluxes, time resolved measurement ITER and α-source profile (i.e. emissivity, neutrons emitted per unit volume). RNC is composed two subsystems, In-Port Ex-Port located, respectively, inside outside Plug Equatorial Port #01. subsystem in a more advanced stage since it has...
A general treatment of the injection-limited currents (ILC) at insulator intersurface, based on continuity equation including source current, is presented. Various approximations are discussed which one-dimensional Onsager model a particular case for weak gradient current or injection distance approaching zero. coordinate-dependent geminate recombination introduced into this model. Formal requirements leading to analytical, tractable solutions divide electric field ( F ) range two regimes:...

The ATLAS inner detector consists of three sub-systems: the pixel spanning radius range 4cm-20cm, semiconductor tracker at radii from 30 to 52 cm, and transition radiation (TRT), tracking 56 107 cm. TRT provides a combination continuous with many projective measurements based on individual drift tubes (or straws) electron identification fibres or foils interleaved between straws themselves. This paper describes off electronics for as well portion data acquisition (DAQ) system.
