Abstract

The Korea Invisible Mass Search (KIMS) collaboration has developed low-background NaI(Tl) crystals that are suitable for the direct detection of WIMP dark matter. Building on experience accumulated during the KIMS-CsI programs, the KIMS-NaI experiment will consist of a 200 kg NaI(Tl) crystal array surrounded by layers of shielding structures and will be operated at the Yangyang underground laboratory. The goal is to provide an unambiguous test of the DAMA/LIBRA annual modulation signature. Measurements of six prototype crystals show progress in the reduction of internal contamination from radioisotopes. Based on our understanding of these measurements, we expect to achieve a background level in the final detector configuration that is less than 1 count/day/keV/kg for recoil energies around 2 keV. The annual modulation sensitivity for the KIMS-NaI experiment shows that an unambiguous 7 $$\sigma $$ test of the DAMA/LIBRA signature would be possible with a 600 kg year exposure with this system.

Abstract

KS 0 KS 0 production in two-photon collisions has been studied using a 397.6 fb-1 data sample collected with the Belle detector at the KEKB e+ e- collider. For the first time the cross sections are measured in the two-photon center-of-mass energy range between 2.4 GeV and 4.0 GeV and angular range | cos θ* | < 0.6. Combining the results with measurements of γ γ → K+ K- from Belle, we observe that the cross section ratio σ (KS 0 KS 0) / σ (K+ K-) decreases from ∼0.13 to ∼0.01 with increasing energy. Signals for the χc 0 and χc 2 charmonium states are also observed. © 2007 Elsevier B.V. All rights reserved.

Abstract

We report measurements of the charmless semileptonic decays B0 → π- / ρ- l+ ν and B+ → π0 / ρ0 l+ ν, based on a sample of 2.75 × 108B over(B, ) events collected at the Υ{hooked} (4 S) resonance with the Belle detector at the KEKB e+ e- asymmetric collider. In this analysis, the accompanying B meson is reconstructed in the semileptonic mode B → D(*) l ν, enabling detection of the signal modes with high purity. We measure the branching fractions B (B0 → π- l+ ν) = (1.38 ± 0.19 ± 0.14 ± 0.03) × 10-4, B (B0 → ρ- l+ ν) = (2.17 ± 0.54 ± 0.31 ± 0.08) × 10-4, B (B+ → π0 l+ ν) = (0.77 ± 0.14 ± 0.08 ± 0.00) × 10-4 and B (B+ → ρ0 l+ ν) = (1.33 ± 0.23 ± 0.17 ± 0.05) × 10-4, where the errors are statistical, experimental systematic, and systematic due to form factor uncertainties, respectively. For each mode we also present the partial branching fractions in three q2 intervals: q2 < 8, 8 ≤ q2 < 16, and q2 ≥ 16 GeV2 / c2. From our partial branching fractions for B → π l ν and recent results for the form factor from unquenched Lattice QCD calculations, we obtain values of the CKM matrix element | Vu b |. © 2007 Elsevier B.V.

Abstract

We report on the response of a high light-output NaI(Tl) crystal to nuclear recoils induced by neutrons from an Am-Be source and compare the results with the response to electron recoils produced by Compton scattered 662 keV $\gamma$-rays from a $^{137}$Cs source. The measured pulse-shape discrimination (PSD) power of the NaI(Tl) crystal is found to be significantly improved because of the high light output of the NaI(Tl) detector. We quantify the PSD power with a quality factor and estimate the sensitivity to the interaction rate for weakly interacting massive particles (WIMPs) with nucleons, and the result is compared with the annual modulation amplitude observed by the DAMA/LIBRA experiment. The sensitivity to spin-independent WIMP-nucleon interactions based on 100 kg$\cdot$year of data from NaI detectors is estimated with simulated experiments, using the standard halo model., Comment: 11pages

Abstract

We have searched for the lepton flavor violating decays τ- → l- KS 0 (l = e or μ), using a data sample of 281 fb-1 collected with the Belle detector at the KEKB e+ e- asymmetric-energy collider. No evidence for a signal was found in either of the decay modes, and we set the following upper limits for the branching fractions: B (τ- → e- KS 0) < 5.6 × 10-8 and B (τ- → μ- KS 0) < 4.9 × 10-8 at the 90% confidence level. These results improve the previously published limits set by the CLEO Collaboration by factors of 16 and 19, respectively. © 2006 Elsevier B.V. All rights reserved.

Abstract

Fundamental informations on performance of sets of solenoid valve and nozzle were necessary to develop a target selectable spraying system. The experiments were performed for the sets of solenoid valves and flat spraying nozzles at 3 levels of the operating pressures, and the obtained results are as follows; Rise time of the system pressure to reach up to 90% of the operating pressure after the valve turned was affected by nozzle size and operating pressure. Maximum overshoot of the system pressure was about 170% not affected by the sets of valve and nozzle and operating pressure. The system pressure after its settle down within 5% of the set pressure showed good uniformity in any condition of the experiment as less as 2.3% of its coefficient of variation. Time requirement to lower the system pressure down to 50% after the valve power turned off was affected by valve and nozzle set and operating pressure.

Abstract

We have searched for neutrinoless τ lepton decays into three charged leptons using an 87.1fb-1 data sample collected with the Belle detector at the KEKB e+e- collider. Since the number of signal candidate events is compatible with that expected from the background, we set 90% confidence level upper limits on the branching fractions in the range (1.9-3.5)×10-7 for various decay modes τ -→l-l+l- where l represents e or μ. © 2004 Published by Elsevier B.V.

Abstract

We have searched for a T/CP violation signature arising from an electric dipole form factor (d_tau) of the tau lepton in the e+e- -> tau+tau- reaction. Using an optimal observable method for 29.5 fb^{-1} of data collected with the Belle detector at the KEKB collider at sqrt{s}=10.58 GeV, we obtained the preliminary result Re(d_tau) = (1.15 +- 1.70) x 10^{-17} ecm and Im(d_tau) = (-0.83 +- 0.86) x 10^{-17} ecm for the real and imaginary parts of d_tau, respectively, and set the 95% confidence level limits -2.2 < Re(d_tau) < 4.5 (10^{-17} ecm) and -2.5 < Im(d_tau) < 0.8 (10^{-17} ecm)., Invited talk at the Seventh International Workshop on Tau Lepton Physics (TAU02), Santa Cruz, Ca, USA, Sept 2002, 8 pages, LaTeX, 19 eps figures

Abstract

This paper describes a study of B meson decays to the pseudoscalar-vector final state \rho\pi using 31.9\times 10^6 B\bar{B} events collected with the Belle detector at KEKB. The branching fractions B(B^+ \to \rho^0\pi^+) = (8.0^{+2.3+0.7}_{-2.0-0.7}) \times 10^{-6} and B(B^0 -> \rho^{+-} \pi^{-+}) = (20.8^{+6.0+2.8}_{-6.3-3.1}) \times 10^{-6} are obtained. In addition, a 90% confidence level upper limit of B(B^0 \to \rho^0\pi^0) < 5.3 \times 10^{-6}is reported.

Abstract

The production of the \chi_{c2} charmonium state in two-photon collisions has been measured with the Belle detector at the KEKB e^+e^- collider. A clear signal for \chi_{c2} --> \gamma J/\psi, J/\psi --> l^+l^- is observed in a 32.6fb^{-1} data sample accumulated at center-of-mass energies near 10.6GeV, and the product of its two-photon decay width and branching fraction is determined to be \Gamma_{\gamma\gamma}(\chi_{c2})B(\chi_{c2} --> \gamma J/\psi) B(J/\psi --> l^+l^-)= 13.5 +/- 1.3(stat.) +/- 1.1(syst.)eV., Comment: 16 pages, 5 figures, to be submitted to Phys.

Abstract

We present a measurement of the Cabibbo–Kobayashi–Maskawa (CKM) matrix element |Vcb| using a 10.2 fb−1 data sample recorded at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric e+e− storage ring. By extrapolating the differential decay width of the B 0 →D ∗+ e − ν decay to the kinematic limit at which the D ∗+ is at rest with respect to the B 0 , we extract the product of |Vcb| with the normalization of the decay form factor F(1), |Vcb|F(1)=(3.54±0.19±0.18)×10−2, where the first error is statistical and the second is systematic. A value of |Vcb|=(3.88±0.21±0.20±0.19)×10−2 is obtained using a theoretical calculation of F(1), where the third error is due to the theoretical uncertainty in the value of F(1). The branching fraction B ( B 0 →D ∗+ e − ν ) is measured to be (4.59±0.23±0.40)×10−2.

Abstract

We present a study of the branching fraction of the decay B0??0?0 and the fraction of longitudinally polarized ?0 mesons in this decay. The results are obtained from the final data sample containing 772�106 BB? pairs collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We find 166�59 B0??0?0 events (including systematic uncertainties), corresponding to a branching fraction of B(B0??0?0)=(1.02�0.30(stat) �0.15(syst))�10-6 with a significance of 3.4 standard deviations and a longitudinal polarization fraction fL=0.21-0.22+0.18(stat)�0. 15(syst). We use the longitudinal polarization fraction to determine the Cabibbo-Kobayashi-Maskawa matrix angle ?2=(84.9�13.5)� through an isospin analysis in the B??? system. We furthermore find 125�41 B0?f0?0 events, corresponding to B(B0?f0?0) �B(f0??+?-)=(0.78�0.22(stat)�0.11(syst)) �10-6, with a significance of 3.1 standard deviations. We find no other significant contribution with the same final state, and set upper limits at 90% confidence level on the (product) branching fractions, B(B0??+?- ?+?-)

Abstract

Interaction of activated platelets and leukocytes (mainly neutrophils) on the activated endothelium mediates thrombosis and vascular inflammation.1,2 During thrombus formation at the site of arteriolar injury, platelets adherent to the activated endothelium and subendothelial matrix proteins support neutrophil rolling and adhesion.3 Conversely, under venular inflammatory conditions, neutrophils adherent to the activated endothelium can support adhesion and accumulation of circulating platelets. Heterotypic platelet-neutrophil aggregation requires sequential processes by the specific receptor-counter receptor interactions between cells.4 It is known that activated endothelial cells release adhesion molecules such as von Willebrand factor, thereby initiating platelet adhesion and accumulation under high shear conditions.5 Also, activated endothelial cells support neutrophil rolling and adhesion by expressing selectins and intercellular adhesion molecule-1 (ICAM-1), respectively, under low shear conditions.4 Platelet P-selectin interacts with neutrophils through P-selectin glycoprotein ligand-1 (PSGL-1), thereby inducing activation of neutrophil β2 integrins and firm adhesion between two cell types. Despite the advances in in vitro experiments in which heterotypic platelet-neutrophil interactions are determined in whole blood or isolated cells,6,7 those studies cannot manipulate oxidant stress conditions during vascular disease. In this report, using fluorescently-labeled, specific antibodies against a mouse platelet and neutrophil marker, we describe a detailed intravital microscopic protocol to monitor heterotypic interactions of platelets and neutrophils on the activated endothelium during TNF-α-induced inflammation or following laser-induced injury in cremaster muscle microvessels of live mice.

Abstract

The DAMA experiment has reported an annual-modulation signal in an array of low-background NaI(Tl) scintillating crystals that may be caused by WIMP-nucleon interactions. However, to date there has been no direct confirmation of this result that uses the same taget nuclides. The Korea Invisible Mass Search (KIMS) collaboration has been engaged in an extensive R&D program to grow ultra-low background NaI(Tl) crystals for use as a direct test of the DAMA result using same nuclide targets. Six crystals were grown from different powders in order to understand mechanisms of internal background contaminations and to reduce their effects. Studies of internal backgrounds in these crystals were performed with the ultimate goal of reducing internal background contamination levels to 1 dru at 2 keV.

Abstract

H.O. KIM AND J.W. YUN. 2005. Aims: The present study comparatively investigates the optimal culture conditions for the production of exopolysaccharides (EPS) and cordycepin during submerged mycelial culture of two entomopathogenic fungi Cordyceps militaris and Cordyceps sinensis. Methods and Results: Fermentations were performed in flasks and in 5-l stirred-tank fermenters. In the case of C. militaris, the highest mycelial biomass (22AE 9gl )1 ) and EPS production (5 g l )1 ) were achieved in a medium of 40 g l )1 sucrose, 5 g l )1 corn steep powder at 30� C, and an initial pH 8AE0. The optimum culture conditions for C. sinensis was shown to be (in g l )1 ) 20 sucrose, 25 corn steep powder, 0AE78 CaCl2 ,1 AE73 MgSO4AE7H2 Oa t 20� C, and an initial pH 4AE0, where the maximum mycelial biomass and EPS were 20AE9 and 4AE 1gl )1 respectively. Cordycepin, another bioactive metabolite, was excreted at low levels during the early fermentation period (maximum 38AE 8m g l )1 in C. militaris ;1 8AE 2m g l )1 in C. sinensis). Conclusions: The two fungi showed different nutritional and environmental requirements in their submerged cultures. Overall, the concentrations of mycelial biomass, EPS and cordycepin achieved in submerged culture of C. militaris were higher than those of C. sinensis. Significance and Impact of the Study: C. militaris and C. sinensis are representative insect-born fungi which have been longstanding and widely used as traditional medicines in eastern Asia. Comparative studies between two fungi are currently not available and this is the first report on the optimum medium composition for submerged culture of C. sinensis.

Abstract

This paper describes power potential approach for the collision-free path planning of stereo-vision based mobile robots. This approach relies on an obstacle detection procedure by stereo matching. We construct the potentials for the robot path planning using sources and sink. The proposed potential distributes sources discretely on the boundaries of obstacles and puts a sink at the goal point and then superpose the power potentials which is defined so that the potential for any one of the source points will have more influence on the robot than the potential for the sink point when the robot is near to source point and the total influence of the source potentials on the robot will be less than that of the sink potential when the robot is more than a defense distance away from the obstacle. We also propose the noble method of escaping from local minima by preserving the directional characteristic of the movement of the mobile robots and using the various potentials simultaneously.

Abstract

The branching fractions and the decay amplitudes of B -> J/psi K^* decays are measured in a 29.4/fb data sample collected with the Belle detector at the KEKB electron-positron collider. The decay amplitudes of helicity states of the J/psi K^* system are determined from the full angular distribution of the final state particles in the transversity basis. The branching fractions are measured to be (1.29\pm0.05\pm0.13) \times 10^{-3} for neutral mesons and (1.28\pm0.07\pm0.14) \times 10^{-3} for charged mesons. The measured longitudinal and transverse (perpendicular to the transversity plane) amplitudes are |A_0|^2 = 0.62\pm0.02\pm0.03 and |A_{\perp}|^2 = 0.19\pm0.02\pm0.03, respectively. The value of |A_{\perp}|^2 shows that the CP even component dominates in the B^0 \to J/\psi K^{*0}(K_S\pi^0) decay., Comment: 17 pages, 3 figures, 5 tables, to appear in Phys. Lett. B

Abstract

The oscillation frequency of B0-B0bar mixing (Delta-m_d) has been measured using 29.1 fb^{-1} of datacollected with the Belle detector at KEKB. This measurement is made through the distributions of the proper decay time difference of B pairs in events tagged as same- and opposite-flavor decays. In each event, one $B$ is fully reconstructed in a flavor-specific hadronic decay mode, while the flavor of the other is extracted through a likelihood calculated from the b-flavor information carried in its final decay products. We obtain Delta-m_d = (0.528 +- 0.017 +- 0.011) ps^{-1}, where the first error is statistical and the second error is systematic., Comment: 15 pages, 3 figures, submitted to Phys. Lett. B

Abstract

We present measurements of the Cabibbo-suppressed decays Lambda_c^+ --> Lambda0 K+ and Lambda_c^+ --> Sigma0 K+ (both first observations), Lambda_c^+ --> Sigma+ K+ pi- (seen with large statistics for the first time), Lambda_c^+ --> p K+ K- and Lambda_c^+ --> p phi (measured with improved accuracy). Improved branching ratio measurements for the decays Lambda_c^+ --> Sigma+ K+ K- and Lambda_c^+ --> Sigma+ phi, which are attributed to W-exchange diagrams, are shown. We also present the first evidence for Lambda_c^+ --> Xi(1690)^0 K+ and set an upper limit on the non-resonant decay Lambda_c^+ --> Sigma+ K+ K-. This analysis was performed using 32.6 fb^{-1} of data collected by the Belle detector at the asymmetric e+ e- collider KEKB., Submitted to Phys. Lett. B. v2: A small correction to the Authorlist was made. An earlier version of this analysis was released as BELLE-CONF-0130, hep-ex/0108003

Abstract

BACKGROUND: The study of the immunogenetics of the human platelet antigens is important to the improvement of diagnosis and genetic counseling and to the development of screening programs for women at risk of having babies with neonatal alloimmune thrombocytopenia. Description of the immunogenetics of the human platelet antigens in some racial groups has been incomplete. STUDY DESIGN AND METHODS: A reverse dot blot technique employing polymerase chain reaction- amplified genomic DNA was applied in genotyping the five major human platelet antigens in the following populations: 100 African American and 100 white women admitted to the obstetric unit at Johns Hopkins Hospital (Baltimore, MD) and 100 inpatients at Yonsei University (Seoul, Korea). RESULTS: The gene frequencies of HPA-2b (Koa) and HPA- 5b (Bra) in African Americans were twice those in whites (African Americans: 0.18 and 0.21, respectively; whites: 0.09 and 0.11, respectively). There is a very low gene frequency of the HPA-1b (PIA2) allele in Koreans (0.005). No significant differences were found in the gene frequencies of the human platelet antigens in whites in this series and those in published European studies. CONCLUSION: These studies indicate a higher potential risk for alloimmunization to HPA-2 (Ko) and HPA-5 (Br) antigens in African Americans than in whites. In addition, the low gene frequency of HPA-1b (PIA2) in African Americans and Koreans suggests that alloimmunization to HPA-1a (PIA1) would be very unusual in these populations. These data may provide the basis for planning neonatal alloimmune thrombocytopenia screening programs in certain ethnic populations.

Abstract

The utility of an enzyme linked immunoassay for the detection of platelet alloantibodies to isolated platelet glycoproteins employing commercially available monoclonal antibodies was studied. The authors established the usefulness of the assay for antibodies to platelet alloantigens (APAA) by testing its sensitivity and specificity under different conditions and using a variety of alloantibodies from patients with immune mediated thrombocytopenia. The authors were able to specifically detect a variety of antibodies to platelet alloantigens on different platelet glycoproteins. These antibodies had specificity for HPA-1a (PI A1 ), HPA-3 (Bak) and HPA-5 (Br). These results show that the APAA is easily adaptable for routine diagnostic testing in hospital laboratories using commercially available monoclonal antibodies and for the diagnosis of alloimmune mediated thrombocytopenic conditions.
