in collisions at = 200 and 62.4 GeV at midrapidity are measured by the PHENIX experiment at the RHIC. We present the inverse slope parameter, mean transverse momentum, and yield per unit rapidity at each energy, and compare them to other measurements at different collisions. We also present the scaling properties such as 
and 
scaling and discuss the mechanism of the particle production in collisions. The measured spectra are compared to next-to-leading order perturbative QCD calculations.

Times Cited Count：9 Percentile：49.6(Physics, Nuclear)Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled collisions. Here we extend these studies to two particle correlations where one particle is an electron from the decay of a heavy flavor meson and the other is a charged hadron from either the decay of the heavy meson or from jet fragmentation. These measurements provide more detailed information about the interaction between heavy quarks and the quark-gluon matter. We find the away-side-jet shape and yield to be modified in Au+Au collisions compared to collisions.

Times Cited Count：52 Percentile：71.15(Biochemistry & Molecular Biology)Here we report the new features and improvements in our latest release of the H-Invitational Database, a comprehensive annotation resource for human genes and transcripts. H-InvDB, originally developed as an integrated database of the human transcriptome based on extensive annotation of large sets of fulllength cDNA (FLcDNA) clones, now provides annotation for 120 558 human mRNAs extracted from the International Nucleotide Sequence Databases (INSD), in addition to 54 978 human FLcDNAs, in the latest release H-InvDB. We mapped those human transcripts onto the human genome sequences (NCBI build 36.1) and determined 34 699 human gene clusters, which could define 34 057 protein-coding and 642 non-protein-coding loci; 858 transcribed loci overlapped with predicted pseudogenes.

Cd using liquid scintillation counterIto, Chihiro; Tanaka, Yasuyuki; Kurosawa, Kiyoko*; Motoki, Yoshiaki*; Do, V. K.; Furuse, Takahiro

In this presentation, an HCl-free analytical method for Cd in aqueous solution samples containing multiple radionuclides by liquid scintillation counting is reported. We aimed to develop a chemical separation procedure of Cd from co-existing nuclides such as 
Co and/or 
Fe, which interfere with the beta-counting. The use of hydrochloric acid (HCl) was avoided to prevent facilities from corrosion. Accordingly, after a sample-matrix separation with a chelating disk, Cd was adsorbed on a cation exchange resin and then selectively eluted by sodium thiosulfate (Na
SO
), which has a high affinity for Cd. This developed method allowed the separation and purification of Cd from the sample matrix without the use of halogen acids.
U using ICP-MS/MSTanaka, Yasuyuki; Do, V. K.; Motoki, Yoshiaki*; Ota, Yuki; Iwahashi, Hiroyuki; Kurosawa, Kiyoko*; Furuse, Takahiro

We examined the measurement method of U using triple-quadrupole inductively coupled plasma-mass spectrometry (ICP-MS/MS, Agilent 8900). The measurable mass to charge ratio (m/z) is expanded up to 275, the device can measure U
OO (m/z = 268) generated by the reaction with O, which was used as a reaction gas. This mass shift mode decreased the interference from hydride of 
U compared to the previously reported analytical method, which improved limit of detection of U using ICP-MS/MS. In this presentation, the optimized measurement condition of U measured at m/z = 268 by ICP-MS/MS is reported.
