Abstract

We study effects of CP violation in a modified bipair neutrino mixing scheme predicting $\sin^2\theta_{23}$ near both 0.4 and 0.6 currently consistent with experimentally allowed values. The source of CP violation is supplied by charged lepton mixing accompanied by a single phase, whose mixing size is assumed to be less than that of the Wolfenstein parameter for the quark mixing. Including results of leptogenesis, which is based on the minimal seesaw model, we obtain the allowed region of CP-violating Dirac and Majorana phases, which provides the observed baryon asymmetry of the universe in the case of the Dirac neutrino mass matrix subject to one zero texture., Comment: 5 pages, 30 figures, accepted for publication in Physics Letters B

Abstract

Abstract: V2O5 thin films were prepared by using pulsed-laser deposition technique. The influences of substrate temperature and oxygen partial pressure on the growth of V2O5 films were studied. X-ray diffraction, atomic force microscopy, Raman measurements and the optical transmission measurements have been carried out in order to understand the growth mechanisms and the electrochromic parameters of the deposited films. We can understand that the structure of the V2O5 thin film deposited at a low substrate temperature was broken by the insertion and extractions of lithium ions with increasing cycle number of electrochemical react. The surface morphology of the films deposited at T s =623K and pO2 =13.3Pa is suitable for an electrochromic devices. [Copyright &y& Elsevier]

34. Electrochemical synthesis of electrochromic Ce–V oxide films in NH4HSO4 melts

Abstract

Cerium oxide and cerium (Ce)–vanadium (V) oxide films were synthesized on an ITO electrode by electrolysis in NH4HSO4–Ce2O3 and NH4HSO4–Ce2O3–NH4VO3 melts at a temperature of about 300 °C. The films obtained were characterized by X-ray diffraction, spectroscopic measurements and electrochemical measurement. In addition, the electrochromic (EC) reactions of the oxide films in a solution of propylene carbonate were investigated. The absorption spectra of Ce–V mixed oxide films obtained by electrodeposition in the NH4HSO4–Ce2O3–NH4VO3 melt showed peaks at 680 and 451 nm, due to a mixed valence of V4+ and V5+ in the orthovanadates (CeVO4), and these absorption peaks increased with Li+ insertion and disappeared with Li+ extraction in EC reactions. The Ce–V mixed oxide films showed a lower absorbance than vanadium oxide and cerium oxide films, respectively in the visible region. [Copyright &y& Elsevier]

Abstract

Computer graphics has been applied in the past to the CAD (computer-aided design) in machine design. However, the technique is recently applied to other fields of industry, and positive attitudes toward CAD are observed in the design of dresses. This paper proposes an algorithm to determine the three-dimensional structure of torsos from basic dress patterns, A method to reconstruct three-dimensional objects from dress patterns is described first, and then the algorithm to texture the torsos is described. By the texturing algorithm, it is made possible to choose cloths and design according to india vidual taste in the form of the completed dress worn on the torso of the customer.

Abstract

A retrospective analysis of clinical features in patients with bronchial asthma who visited the emergency clinic of Nagaoka Red Cross Hospital or were admitted to it between 1980 and 1986 are performed. In 1986, 1841 patients visited for bronchial asthmatic attacks, which occupied 11.4% of all patients and 24.3% of those who were treated by physician. The time when they visited frequently was 6 pm to 10 pm. Most patients aged less than 20 years old visited from Summer to Autumn, suggesting that their disorders was atopic type mainly, whereas those aged more than 21 years old visited for all seasons constantly, indicating that their type was cryptogenic. In 10 of 662 inpatients with bronchial asthma over seven-year period, sever attacks were associated with unconciousness (20 episodes) and 12 occasions among them recovered without artificial ventilation, whereas 8 requiered intubation or mechanical ventilation. No significant difference in degree of respiratory acidosis, hypoxemia or hypercapnia was observed in the two groups. Six of all patients died of status asthmaticus, 2 of them fell into respiratory arrest in an ambulance car, 3 died in the emergency ward despite of various treatments and 1 died from complication of tuberculosis. From these findings, signs and symptoms of life-threatening asthma and indication of artificial ventilation are discussed.
