ABSTRACT: We present a measurement of the time-dependent CP violation parameters in B0
-> pi+ pi- decays. The results are obtained from the final data sample
containing 772 million BBbar pairs collected at the Upsilon(4S) resonance with
the Belle detector at the KEKB asymmetric-energy e+e- collider. We obtain the
CP violation parameters Acp = +0.33 +/- 0.06 (stat) +/- 0.03 (syst) and Scp =
-0.64 +/- 0.08 (stat) +/- 0.03 (syst), where Acp and Scp represent direct and
mixing-induced CP violation, respectively. From an isospin analysis including
results from other Belle measurements, we rule out 23.8 < phi2 < 66.8 degrees
at the 1 sigma level.

ABSTRACT: We present a study of the branching fraction of the decay B^0 -> rho^0 rho^0
and the fraction of longitudinally polarized \rho^0 mesons in this decay. The
results are obtained from the final data sample containing $772 \times 10^{6}$
$B\bar{B}$ pairs collected at the $\Upsilon(4S)$ resonance with the Belle
detector at the KEKB asymmetric-energy e^+e^- collider. We find $166 \pm 59$
B^0 -> rho^0 rho^0 events, corresponding to a branching fraction of ${\cal
B}(B^0 -> rho^0 rho^0) = (1.02\pm 0.30 (\rm stat) \pm 0.22 (\rm syst))\times
10^{-6} $ with a longitudinally polarization fraction $f_L =
0.21^{+0.18}_{-0.22} (\rm stat) \pm 0.11 (\rm syst)$. The branching fraction's
upper limit is ${\cal B}(B^0 -> rho^0 rho^0) < 1.5 \times 10^{-6}$ at 90%
confidence level. We use the longitudinal polarization fraction to determine
the Cabibbo-Kobayashi-Maskawa matrix angle $\phi_2 = (91.0 \pm 7.2)^{\circ}$
through an isospin analysis in the $B\to\rho\rho$ system. We furthermore obtain
${\cal B}(B^0 -> rho^0 f_0) \times {\cal B}(f_0 -> \pi^+\pi^-) = (0.86 \pm 0.27
(\rm stat) \pm 0.15 (\rm syst))\times 10^{-6}$, corresponding to $149 \pm 49$
$B^0 -> rho^0 f_0$ events with a significance of 3.0 standard deviations and
upper limits at 90% confidence level on the (product) branching fractions for
possible decays with the same final state, ${\cal B}(B^0 -> pi^+\pi^-pi^+\pi^-)
< 11.7 \times 10^{-6} $, ${\cal B}(B^0 -> rho^0 pi^+\pi^-) < 12.2 \times
10^{-6}$, ${\cal B}(B^0 -> f_0 pi^+\pi^-) \times {\cal B}(f_0->\pi^+\pi^-) <
3.1 \times 10^{-6}$ and ${\cal B}(B^0 -> f_0 f_0) \times {\cal
B}(f_0->\pi^+\pi^-)^{2} < 0.2 \times 10^{-6}$.

ABSTRACT: We measure the branching fraction of B- -> tau- nu_tau-bar using the full
Upsilon(4S) data sample containing 772*10^6 BBbar pairs collected with the
Belle detector at the KEKB asymmetric-energy e+e- collider. Events with BBbar
pairs are tagged by reconstructing one of the B mesons decaying into hadronic
final states, and B- -> tau- nu_tau-bar candidates are detected in the recoil.
We find evidence for B- -> tau- nu_tau-bar with a significance of 3.0 standard
deviations including systematic errors and measure a branching fraction B(B- ->
tau- nu_tau-bar) = [0.72^{+0.27}_{-0.25}(stat) +/- 0.11(syst)] * 10^-4.

ABSTRACT: We present a precise measurement of the CP violation parameter sin2φ1 and the direct CP violation parameter A(f) using the final data sample of 772×10(6) BB[over ¯] pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. One neutral B meson is reconstructed in a J/ψK(S)(0), ψ(2S)K(S)(0), χ(c1)K(S)(0), or J/ψK(L)(0) CP eigenstate and its flavor is identified from the decay products of the accompanying B meson. From the distribution of proper-time intervals between the two B decays, we obtain the following CP violation parameters: sin2φ1=0.667±0.023(stat)±0.012(syst) and A(f)=0.006±0.016(stat)±0.012(syst).

ABSTRACT: We report a new sensitive search for CPT violation, which includes improved
measurements of the CPT-violating parameter z and the total decay-width
difference normalized to the averaged width DeltaGamma_d/Gamma_d of the two Bd
mass eigenstates. The results are based on a data sample of 535 x 10^6 BBbar
pairs collected at the Upsilon(4S) resonance with the Belle detector at the
KEKB asymmetric-energy e^+e^- collider. We obtain Re(z) = [+1.9 +/- 3.7 (stat)
+/- 3.3 (syst)] x 10^{-2}, Im(z) = [-5.7 +/- 3.3 (stat) +/- 3.3 (syst)] x
10^{-3}, and DeltaGamma_d/Gamma_d = [-1.7 +/- 1.8 (stat) +/- 1.1 (syst)] x
10^{-2}, all of which are consistent with zero. This is the most precise single
measurement of these parameters in the neutral B-meson system to date.

ABSTRACT: Phenylalanine is an essential amino acid required for the synthesis of catecholamines including dopamine. Altered levels of phenylalanine and its metabolites in blood and cerebrospinal fluid have been reported in schizophrenia patients. This study attempted to examine for the first time whether phenylalanine kinetics is altered in schizophrenia using L-[1-(13)C]phenylalanine breath test ((13)C-PBT). The subjects were 20 chronically medicated schizophrenia patients (DSM-IV) and the same number of age- and sex-matched controls. (13)C-phenylalanine (99 atom% (13)C; 100 mg) was administered orally and the breath (13)CO(2) /(12)CO(2) ratio was monitored for 120 min. The possible effect of antipsychotic medication (risperidone (RPD) or haloperidol (HPD) treatment for 21 days) on (13)C-PBT was examined in rats. Body weight (BW), age and diagnostic status were significant predictors of the area under the curve of the time course of Δ(13)CO(2) (‰) and the cumulative recovery rate (CRR) at 120 min. A repeated measures analysis of covariance controlled for age and BW revealed that the patterns of CRR change over time differed between the patients and controls and that Δ(13)CO(2) was lower in the patients than in the controls at all sampling time points during the 120 min test, with an overall significant difference between the two groups. Chronic administration of RPD or HPD had no significant effect on (13)C-PBT indices in rats. Our results suggest that (13)C-PBT is a novel laboratory test that can detect altered phenylalanine kinetics in chronic schizophrenia patients. Animal experiments suggest that the observed changes are unlikely to be attributable to antipsychotic medication.

ABSTRACT: We present a novel electrostatic suspension system that is cost-effective and has good suspension performance. The main feature of the system is that movable electrodes are employed to implement a stable suspension instead of the stationary electrodes employed in previous suspension systems. In this system, the movable electrodes are powered by constant voltage, and their movements are controlled by piezoelectric actuators with rapid deformation characteristics, which allow the electrostatic forces exerted on a suspended object to be controlled by variation of the gap length between the suspended object and the movable electrodes. We describe the structure, operational principle, dynamic model, and a stabilization method of the suspension system, followed by an experimental setup. Experimental results demonstrate the complete suspension of a 4 in silicon wafer without any mechanical contact.

ABSTRACT: This work describes the use of a novel palygorskite, a type of magnesium aluminium silicate clay possessing a high specific surface area and pore surface activity, as a low cost and highly efficient adsorbent for hydrogen sulfide (H(2)S) removal. Adsorption of H(2)S on palygorskite pretreated with acid or base was investigated in a fixed bed adsorber. The samples after base pretreatment had better dynamic adsorption performances than raw material and samples pretreated with acid. The H(2)S adsorption capacity decreased with an increase in inlet H(2)S concentration. This can be interpreted by the fact that H(2)S adsorption on the surface of palygorskite is chemisorption. The adsorption capacity increased from 25 to 50 °C, then decreased from 50 to 100 °C, which indicates that chemisorption took place and its better reaction temperature was around 50 °C.

ABSTRACT: The aim of the present study was to show a relationship between toxicity of 100-fold concentrated water and aquatic habitat conditions. Environmental waters are 100-fold concentrated with solid-phase extraction. Medaka early fry was exposed in these waters for 48 h. The number of death and disorder was counted at 1, 2, 3, 6, 12, 24, and 48 h; toxicity was expressed using inverse median effect time and median lethal time (ET (50)(-1), LT (50)(-1)). Average score per taxon (ASPT) for benthic animals and Index of Biotic Integrity (IBI) for fish were applied as indices of aquatic habitat conditions. The results of toxicity test were compared using ASPT and IBI. The different levels of toxicity were detected in the seawater of Japan. At the Husino River area, toxicity cannot be detected. In rivers, high toxicity appeared at urban districts without sewerage. By Spearman coefficient, the relationship between toxicity and high biochemical oxygen demand (BOD) were obtained. BOD household wastewater contains hydrophobic toxic matters; otherwise, seawater in industrial area does not show clear relationship between toxicity and chemical oxygen demand. Gas chromatography to mass spectrometry simultaneous analysis database may give an answer for the source of toxicity, but further test is required. Ratio of clear stream benthic animal sharply decreased over 0.25 of LT (50)(-1) or 0.5 of ET (50)(-1). Tolerant fish becomes dominant over 0.3 of LT (50)(-1) or 0.5-1.0 of ET (50)(-1). By Pearson product-moment correlation coefficient, correlation coefficient between toxicity and ASPT was obtained at -0.773 (ET (50)(-1)) and -0.742 (LT (50)(-1)) at 1 % level of significance with a high negative correlation. Toxicity (LT (50)(-1) ) has strong correlation with the ratio of tolerant species. By Pearson product-moment correlation coefficient, correlation coefficient between toxicity and IBI obtained were -0.155 (ET (50)(-1)) and -0.190 (LT (50)(-1)) at 1 % level of significance and has a low or no correlation between toxicity and IBI. Even with low toxic environmental waters, toxicity test using 100-fold concentrated and medaka early fly could detect acute toxicity. The detected toxicity seemed to limit the inhabiting aquatic species in the water body.

ABSTRACT: This paper describes a motor driver circuit for a high-power electrostatic motor using Field Programmable Gate Array (FPGA). Electrostatic actuators are popular in the field of micron or nano technologies but some high-power electrostatic motors have been developed for normal-sized applications. Dual Excitation Multiphase Electrostatic Drive (DEMED) is one of the strongest actuators among them. There are various driving methods for the motor (DEMED), however, regardless of driving methods, developing driving circuits is one of the difficulties for practical applications. To operate the motor, one or two three-phase signals are required and amplitudes of them must be a few kV. Hence multi-channel signal synthesizers and high-power amplifiers are needed for driver circuits. In addition, portability is required for some applications as well. In this research, therefore, quad Direct Digital Synthesizers (DDS) are built inside the one FPGA. In the performance evaluation, this driver circuit generates motor driving signals based on the position command that is given by a higher-level controller. It is confirmed that the electrostatic motor operates following reference position data, by using this FPGA-based motor driver.

ABSTRACT: Pinning effect of a bulk high-temperature superconductor (HTS) has various possible applications, e.g., it enables a non-contact and stable levitation without active control. Regarding the magnetic levitation with HTSs, permanent magnets are generally employed, but our previous studies have demonstrated that the permanent magnets can be replaced with soft magnetic materials such as iron. When the magnetic levitation is applied to large transportation system, the use of this technique has a potential to allow a low-cost levitation system with a simple structure, in which expensive permanent magnets can be eliminated. In the mechanical design, a dynamic evaluation as well as a static evaluation must be needed. Hence, this paper fundamentally discusses dynamic properties of the magnetic levitation modulated by a damped harmonic oscillator model. For the dynamic analysis, this paper proposes a novel measurement method using repetitive control. The analysis shows that the dynamic properties of our system are related to the approach manner-process and speed-of the soft magnetic material to the HTS. It is expected that these results may shed further light on the design of efficient levitation system with HTSs.

ABSTRACT: Eu doped rare-earth orthovanadates are known to be good red phosphor materials. In particular, LaVO4:Eu is a promising candidate due to the low Eu-site point symmetry, and thus high dipole transition probability within Judd–Ofelt theory. However, the low solubility limit (<3 mol %) of Eu in LaVO4 prevents its efficient use as a phosphor. We present optical evidence of enhanced Eu solubility as high as 10 mol % in LaVO4:Eu thin films grown by pulsed laser deposition and postannealing. The photoluminescent intensity exceeded that of YVO4:Eu thin films when excited below the host bandgap, indicating stronger direct emission of Eu in LaVO4.

ABSTRACT: The current 3D XCAT phantom allows users to manually define the regional myocardial perfusion defect (MPD) as a simple pie-shaped wedge region with reduced activity level in the myocardium of left ventricle. To more accurately and realistically model the MPD, we have developed a new regional MPD model for the 3D XCAT phantom for myocardial perfusion SPECT (MP-SPECT) studies based on the location and the severity of the stenosis in a computer generated coronary arterial tree. First, we generated a detailed coronary arterial tree by extending the large proximal branches segmented from patient CT images to cover the whole heart using an iterative rule-based algorithm. Second, we determined the affected downstream vascular segments of a given stenosis. Third, we computed the activity of each myocardial region as a function of the inverse-distance-weighted average of the flow of the neighboring vascular segments. Fourth, we generated a series of bull's-eye maps of MP-SPECT images of different coronary artery stenosis scenarios. Fifth, we had expert physician readers to qualitatively assess the bull's-eye maps based on their similarity to typical clinical cases in terms of the shape, the extent, and the severity of the MPDs. Their input was used to iteratively revise the coronary artery tree model so that the MPDs were closely matched to those found in bull's-eye maps from patient studies. Finally, from our simulated MP-SPECT images, we observed that (1) the locations of the MPDs caused by stenoses at different main arteries were different largely according to their vascular territories, (2) a stenosis at a proximal branch produced a larger MPD than the one at a distal branch, and (3) a more severe stenosis produced a larger MPD than the less severe one. These observations were consistent to those found in clinical cases. Therefore, this new regional MPD model has enhanced the generation of realistic pathological MP-SPECT images using the XCAT phantom. When combining w-

ith the mechanical model of the myocardium, the new model can be extended for the simulation of 4D gated MP-SPECT simulation of a pathological heart with both perfusion and motion defects.

ABSTRACT: Electrostatic levitation holds great promise for the semiconductor, solar panel, and flat-panel display industry where the handling of dielectrics in a contact-free manner can bring many advantages and solve long-standing contamination and particulate control problems. In this work an analytical model is developed for the electrostatic levitation field between a lossy dielectric plate and a generic stator electrode structure consisting of a regular planar array of parallel bar electrodes. Time-varying voltages of differing polarities are alternatingly applied to the bar electrodes. Atmospheric humidity-related surface conduction on the plate is explicitly taken into account in the model since it has a profound effect on the field dynamics. Based on this model, the electrostatic levitation force is calculated using the Maxwell stress tensor formulation. The levitation force dynamics are investigated by evaluating the transient response of the field under a step in the applied voltages. In this context, the rate of electric charge build up on the plate is characterized by the suspension initiation time (T<sub> SI </sub>) , which is defined as the time elapsed between applying step voltages to the stator electrodes and start of lift-off of the dielectric plate from its initial position. T<sub> SI </sub> is theoretically predicted for 0.7 mm thick soda-lime glass substrates, typically used in the manufacturing of liquid crystal displays (LCDs), as a function of electrode geometry, air gap separation, ambient humidity, and step voltage magnitudes. The predicted results are shown to be in good agreement with previously published experimental data for soda-lime glass substrates.

ABSTRACT: The present study describes a frequency spectrum classification method for fault detection of the LP gas pressure regulator using support vector machines (SVMs). Conventional diagnosis methods are inefficient because of problems such as significant noise and non-linearity of the detection mechanism. In order to address these problems, a machine learning method with a divergence-based kernel is introduced into spectrum classification. The authors use the normalised frequency spectrum directly as input with the divergence-based kernel. The proposed method is applied to the vibration spectrum classification of the rubber diaphragm in a pressure regulator. As a result, the classification performance using the divergence-based kernel is shown to be better than when using common kernels such as the Gaussian kernel or the polynomial kernel. The high classification performance is achieved by using an inexpensive sensor system and the machine learning method. The proposed method is widely applicable to other spectrum classification applications without limitation on the generality if the spectra are normalised.

ABSTRACT: The Belle detector at the KEKB electron-positron collider has collected almost 1 billion Y(4S) events in its decade of operation. Super-KEKB, an upgrade of KEKB is under construction, to increase the luminosity by two orders of magnitude during a three-year shutdown, with an ultimate goal of 8E35 /cm^2 /s luminosity. To exploit the increased luminosity, an upgrade of the Belle detector has been proposed. A new international collaboration Belle-II, is being formed. The Technical Design Report presents physics motivation, basic methods of the accelerator upgrade, as well as key improvements of the detector. Comment: Edited by: Z. Dole\v{z}al and S. Uno
