We study the dynamics of high energy heavy ion collisions through Vlasov-Uehling-Uhlenbeck approach. Equilibration is observed, for central collisions. It shown that produced entropy, pion multiplicity, flow angle, and transverse momentum distributions saturate at moment maximum compression temperature. The effects nuclear equation state Pauli principle are investigated. For angle distribution there a 20 deg reduction peak due to principle. A stiff results in 10--20 increase over soft all...
SUMMARY The characteristics of IBT-dependent (IBT d ) and IBT-resistant r mutants vaccinia virus were compared with those the wild type (wt) strain. did not differ from strain by their sedimentation in sucrose gradients. Minor differences polypeptide composition particles neutralization three strains anti-vaccinia human immunoglobulin observed. Mixed infections viruses HeLa cells enabled growth under unfavourable conditions (wt presence IBT absence IBT).
Virazole or Ribavirin (1-beta-D-ribofuranosyl-1,2,4-triazole-3-carboxamide) inhibits the growth of vaccinia virus at a concentration ode to certain extent in presence Virazole, DNA fails acquire resistance deoxyribonuclease and particles are not formed. Reversibility antiviral effect occurs when drug is washed out from infected cultures guanosine an equimolar added.
Microbiology Society journals contain high-quality research papers and topical review articles. We are a not-for-profit publisher we support invest in the microbiology community, to benefit of everyone. This supports our principal goal develop, expand strengthen networks available members so that they can generate new knowledge about microbes ensure it is shared with other communities.
We present searches for quark-lepton compositeness and a heavy W' boson at high electron-neutrino transverse mass. use ~110/pb of data collected in p-pbar collisions sqrt(s) = 1.8 TeV by the CDF collaboration during 1992--95.

We exclude < 2.81 below 754 GeV/c^2 95% confidence level. combine...
During the High Luminosity LHC, CMS detector will need charged particle tracking at hardware trigger level to maintain a manageable rate and achieve its physics goals. The tracklet approach is track-finding algorithm based on road-search that has been implemented commercially available FPGA technology. achieved high performance in completes within 3.4 μs Xilinx Virtex-7 FPGA. An overview of implementation an given, results are shown from demonstrator test stand system studies presented.
The high instantaneous luminosities expected following the upgrade of Large Hadron Collider (LHC) to High-Luminosity LHC (HL-LHC) pose major experimental challenges for CMS experiment.A central component allow efficient operation under these conditions is reconstruction charged particle trajectories and their inclusion in hardwarebased trigger system.There are many involved achieving this: a large input data rate about 20-40 Tb/s; processing new batch every 25 ns, each consisting 15,000...
SUMMARY IBT-related compounds were examined for their ability to inhibit wild-type and IBT-resistant mutants of vaccinia virus capability support the growth an IBT-dependent mutant. Among thirteen tested, six did not affect any one three strains five behaved similarly IBT, but two inhibited all viruses therefore differed from IBT. It was found that last also IBT in they interfered with synthesis DNA. This difference is surprising view a substantial similarity chemical structure.
▪ Abstract Since the discovery of bottom quark in 1977, physicists have searched for top quark, weak isospin partner quark. Indirect evidence and estimates its mass been made; however, direct observation eluded scientists until recently. In spring 1995, two experiments, CDF DØ, at Fermi National Accelerator Laboratory showed top-antitop pairs created from proton-antiproton collisions. this report, we summarize experimental status prior to 1995 discuss experiments techniques that March...
SUMMARY The IBT-dependent mutant of vaccinia virus needs IBT for its growth. is not essential the synthesis DNA, but formed DNA does become resistant to deoxyribonuclease in absence. Both ‘early’ and ‘late’ proteins are synthesized cells infected with mutant, absence one core structural polypeptides, which normally from a higher mol. wt. precursor, made. These findings suggest that step occurs earlier maturation process than block produced by wild-type strain.
Tilorone hydrochloride, at a concentration of 10 mug/ml inhibits the growth herpes simplex virus type 1 in BS-C-1 cells. The vaccinia cells is partially inhibited; however, six viruses containing RNA, including four members togavirus group grown chick fibroblasts, are not affected by drug. inhibition tilorone hydrochloride greater when multiplicity infection lower than p.f.u/cell and drug added early course infection.
Run II at the Tevatron is scheduled to start in March 2001. The accelerator complex and collider detectors are undergoing substantial upgrades. This has motivated a complete redesign of online-trigger system for Collider Detector Fermilab (CDF). CDF trigger three-level architecture that will reduce 7.6 MHz crossing rate 50 Hz written tape.

A trigger track processor is being designed for the CDF upgrade. This identifies high momentum (P/sub T/>1.5 GeV/c) charged tracks in new central outer tracking chamber II. The called eXtremely Fast Tracker (XFT). XFT design highly parallel to handle input fate of 183 Gbits/sec and output rate 44 Gbits/sec. pipelined reports results a event every 132 ns. uses three stages, hit classification, segment finding, linking. pattern recognition algorithms stages are implemented programmable logic...
We study effects of the mean field in hot compressed nuclear matter context Vlasov Uehling-Uhlenbeck theory. The expansion a spherical distribution at different temperatures is studied along with collisions Nb+Nb and Au+Au lab energies from 50 to 1050 MeV/nucleon. In both actual heavy ion collision simulation, transition behavior seen only lowest temperature (T10 MeV) or bombarding energy (E=50 MeV/nucleon), where attractive part able bind expanding matter. At one thus sees formation central...
The association of newly synthesized vaccinia virus DNA with proteins in infected HeLa cells was followed. A shift from a high density to low complex occurred between 3 and 6 h after infection. This process not affected by isatin beta thiosemicarbazone (IBT), an inhibitor pox growth. At 22 infection the absence IBT, mature virions were observed; however, presence drug, DNA-protein complexes, which lack two main core polypeptides, formed.
The upgrades of the Compact Muon Solenoid particle physics experiment at CERN's Large Hadron Collider provide a major challenge for real-time collision data selection. This paper presents novel approach to pattern recognition and charged trajectory reconstruction using an all-FPGA solution. challenges include large input rate about 20 40 Tbps, processing new batch every 25 ns, each consisting 10,000 precise position measurements particles (`stubs'), perform on these stubs find trajectories,...
