NICOS System of Nightly Builds for Distributed Development

NICOS, NIghtly COntrol System, is a flexible tool for coordination of software development in large-scale projects. It manages the multi-platform nightly builds based on the recent versions of software packages, tries to compensate for technical failures, tests the newly built software, identifies possible problems, and makes results immediately available to developers spread over different institutions and countries. The NICOS nightly build services ensure that new software submissions are consistent and provide expected results. The NICOS tool was developed to coordinate the efforts of more than 100 developers from 34 countries for the ATLAS project at CERN and can be easily adapted for other large software projects.Comment: Talk from the 2003 Computing in High Energy and Nuclear Physics (CHEP03), La Jolla, Ca, USA, March 2003, 4 pages, LaTeX, 2 eps figures.

Analysis of BKO Content (Antalgin and Dexamethasone) in Herbal Medicine Using Iodimetry Titration and HPLC Method

Abstract : Misuse of adding chemical drugs – BKO – into herbal medicines is often done by irresponsible people. The aim is to increase efficacy instantly, to attract consumer interest. BKO, which are often added to herbal medicine, are antalgin and dexamethasone. Antalgin content analysis was carried out quantitatively using the iodimetry titration method by conducting a preliminary test. The dexamethasone content analysis was carried out with qualitative and quantitative methods. The qualitative method was carried out using TLC. The quantitative method was carried out using the HPLC technique. The results obtained for the analysis of antalgin content of 10 samples were obtained two samples of herbal medicine containing antalgin, respectively 0,0749% and 0,1083%. Analysis of the dexamethasone content from 10 samples obtained 5 herbal samples containing dexamethasone respectively 0.0979%, 0.222%, 0.4521%, 0.5131% and 0.2809%. So based on these results, it is necessary to take action from the relevant institution regarding the discovery of the content of BKO in the herbal medicine on the market in Lombok.Abstrak : Penyalahgunaan penambahan bahan kimia obat (BKO) kedalam jamu sering sekali dilakukan oleh oknum yang tidak bertanggung jawab. Hal ini dilakukan dengan tujuan meningkatkan khasiat secara instan, sehingga dapat menarik minat konsumen. BKO yang sering ditambahkan kedalam jamu adalah antalgin dan deksametason. Analisis kandungan antalgin dlakukan dengan cara kuantitatif menggunakan metode titrasi iodimetri dengan melakukan uji pendahuluan. Sedangkan analisis kandungan deksametason dilakukan dengan metode kualitatif dan kuantitatif. Metode kualitatif dilakukan dengan menggunakan KLT. Metode kuantitatif dilakukan dengan menggunakan teknik HPLC. Hasil yang diperoleh untuk analisis kandungan antalgin dari 10 sampel didapat 2 sampel jamu yang mengandung antalgin masing-masing sebesar 0,0749% dan 0,1083%. Analisis kandungan deksametason dari 10 sampel diperoleh 5 sampel jamu yang mengandung deksametason masing masing sebesar 0,0979%; 0,222%; 0,4521%; 0,5131% dan 0,2809%. Sehingga berdasarkan hasil tersebut maka perlu dilakukan adanya tindakan dari instansi terkait perihal masih ditemukannya kandungan BKO dalam sediaan jamu yang beredar di pasaran pulau Lombok

Rate Measurement of D0→K+π−π0D^{0}\to K^{+}\pi^{-}\pi^{0} and Constraints on D0−D0‾D^{0} - \overline{D^{0}} Mixing

We present an observation and rate measurement of the decay D0 -> K+pi-pi0 produced in 9/fb of e+e- collisions near the Upsilon(4S) resonance. The signal is inconsistent with an upward fluctuation of the background by 4.9 standard deviations. We measured the rate of D0 -> K+pi-pi0 normalized to the rate of D0bar -> K+pi-pi0 to be 0.0043 +0.0011 -0.0010 (stat) +/- 0.0007 (syst). This decay can be produced by doubly-Cabibbo-suppressed decays or by the D0 evolving into a D0bar through mixing, followed by a Cabibbo-favored decay to K+pi-pi0. We also found the CP asymmetry A=(8 +25 -22)% to be consistent with zero.Comment: 10 pages postscript, also available through http://w4.lns.cornell.edu/public/CLN

First Observation of barB0 to D*0 pi+pi+pi-pi- Decays

We report on the observation of B0bar -> D*0 pi+ pi+ pi- pi- decays. The branching ratio is (0.30 +/- 0.07 +/- 0.06)%. Interest in this particular mode was sparked by Ligeti, Luke and Wise who propose it as a way to check the validity of factorization tests in B0bar -> D*+ pi+ pi- pi- pi0 decays.Comment: 11 pages postscript, also available through http://w4.lns.cornell.edu/public/CLNS, Version to appear in Phys.

A Search for Charmless B→VVB\to VV Decays

We have studied two-body charmless decays of the $B$ meson into the final states $\rho^0 \rho^0$, $K^{*0} \rho^0$, $K^{*0} K^{*0}$, $K^{*0} \bar{K^{*0}}$, $K^{*+} \rho^0$, $K^{*+} \bar{K^{*0}}$, and $K^{*+} K^{*-}$ using only decay modes with charged daughter particles. Using 9.7 million $B \bar{B}$ pairs collected with the CLEO detector, we place 90% confidence level upper limits on the branching fractions, $(0.46-7.0)\times 10^{-5}$, depending on final state and polarization.Comment: 8 pages postscript, also available through http://w4.lns.cornell.edu/public/CLN

Search for a Scalar Bottom Quark with Mass 3.5-4.5 GeV/c2c^{2}

We report on a search for a supersymmetric $\tilde{B}$ meson with mass between 3.5 and 4.5 GeV/$c^2$ using 4.52 ${\rm fb}^{-1}$ of integrated luminosity produced at $\sqrt{s}=10.52$ GeV, just below the $e^+e^-\to B\bar{B}$ threshold, and collected with the CLEO detector. We find no evidence for a light scalar bottom quark.Comment: 10 pages postscript, also available through http://w4.lns.cornell.edu/public/CLN

Observation of New States Decaying into Λc+π−π+\Lambda_{c}^{+}\pi^{-}\pi^{+}

Using 13.7 fb^{-1} of data recorded by the CLEO detector at CESR, we investigate the spectrum of charmed baryons which decay into Lambda_c^+ pi^- pi^+ and are more massive than the Lambda_{c1} baryons. We find evidence for two new states: one is broad and has an invariant mass roughly 480 MeV above that of the Lambda_c^+; the other is narrow with an invariant mass of 596 +- 1 +- 2 MeV above the Lambda_c^+ mass. These results are preliminary.Comment: 11 pages postscript, also available through http://w4.lns.cornell.edu/public/CLN

Hadronic Mass Moments in Inclusive Semileptonic B Meson Decays

We have measured the first and second moments of the hadronic mass-squared distribution in B -> X_c l nu, for P(lepton) > 1.5 GeV/c. We find <M_X^2 - M_D[Bar]^2> = 0.251 +- 0.066 GeV^2, )^2 > = 0.576 +- 0.170 GeV^4, where M_D[Bar] is the spin-averaged D meson mass. From that first moment and the first moment of the photon energy spectrum in b -> s gamma, we find the HQET parameter lambda_1 (MS[Bar], to order 1/M^3 and beta_0 alpha_s^2) to be -0.24 +- 0.11 GeV^2. Using these first moments and the B semileptonic width, and assuming parton-hadron duality, we obtain |V_cb| = 0.0404 +- 0.0013.Comment: 11 pages postscript, also available through http://w4.lns.cornell.edu/public/CLNS, submitted to PR

Correlated /\c-/\cbar production in e+e- annihilations at sqrt{s}~10.5 GeV

Using 13.6/fb of continuum two-jet e+e- -> ccbar events collected with the CLEO detector, we have searched for baryon number correlations at the primary quark level. We have measured the likelihood for a /\c+ charmed baryon to be produced in the hemisphere opposite a /\c- relative to the likelihood for a /\c+ charmed baryon to be produced opposite an anticharmed meson Dbar; in all cases, the reconstructed hadrons must have momentum greater than 2.3 GeV/c. We find that, given a /\c- (reconstructed in five different decay modes), a /\c+ is observed in the opposite hemisphere (0.72+/-0.11)% of the time (not corrected for efficiency). By contrast, given a Dbar in one hemisphere, a /\c+ is observed in the opposite hemisphere only (0.21+/-0.02)% of the time. Normalized to the total number of either /\c- or Dbar ``tags'', it is therefore 3.52+/-0.45+/-0.42 times more likely to find a /\c+ opposite a /\c- than a Dbar meson. This enhancement is not observed in the JETSET 7.3 e+e- -> ccbar Monte Carlo simulation.Comment: 19 pages, Latex, one figure separat

Bounds on the CP Asymmetry in Like-Sign Dileptons from B0Bˉ0B^{0}\bar{B}^{0} Meson Decays

We have measured the charge asymmetry in like-sign dilepton yields from B^0 B^0-bar meson decays using the CLEO detector at the Cornell Electron Storage Ring. We find a_ll = [N(l+l+) - N(l-l-)]/[N(l+l+) + N[l-l-)] = +0.013 +/- 0.050 +/- 0.005 . We combine this result with a previous, independent measurement and obtain Re(epsilon_B)/(1+|epsilon_B|^2) = +0.0035 +/- 0.0103 +/- 0.0015 (uncertainties are statistical and systematic, respectively) for the CP impurity parameter, epsilon_B.Comment: 11 pages postscript, also available through http://w4.lns.cornell.edu/public/CLN
