We present measurements of nu_mu disappearance in K2K, the KEK to Kamioka long-baseline neutrino oscillation experiment. One hundred and twelve beam-originated events are observed fiducial volume Super-Kamiokande with an expectation 158.1^{+9.2}_{-8.6} without oscillation. A distortion energy spectrum is also seen 58 single-ring muon-like reconstructed energies. The probability that observations explained by for no 0.0015% (4.3sigma). In a two flavor scenario, allowed Delta m^2 region at...
We present results for ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ oscillation in the KEK to Kamioka (K2K) long-baseline neutrino experiment. K2K uses an accelerator-produced beam with a mean energy of 1.3 GeV directed at Super-Kamiokande detector. observed energy-dependent disappearance ${\ensuremath{\nu}}_{\ensuremath{\mu}}$, which we presume have oscillated ${\ensuremath{\nu}}_{\ensuremath{\tau}}$. The probability that would observe these if there is no 0.0050% ($4.0\ensuremath{\sigma}$).
The weak nucleon axial-vector form factor for quasi-elastic interactions is determined using neutrino interaction data from the K2K Scintillating Fiber detector in beam at KEK. More than 12,000 events are analyzed, of which half charged-current nu-mu n to mu- p occurring primarily oxygen nuclei. We use a relativistic Fermi gas model and assume approximately dipole with one parameter, axial vector mass M_A, fit shape distribution square momentum transfer nucleus. Our best result M_A = 1.20...
Brain injury induces phenotypic changes in astrocytes, known as reactive astrogliosis, which may influence neuronal survival. Here we show that brain inositol 1,4,5-trisphosphate (IP 3 )-dependent Ca 2+ signaling and the is required for astrogliosis. We found type 2 IP receptor knockout R2KO) mice deficient astrocytic have impaired astrogliosis increased injury-associated death. identified N-cadherin pumilio (Pum2) downstream molecules, up-regulation of around injured site. This effect...
We report the result from a search for charged-current coherent pion production induced by muon neutrinos with mean energy of 1.3 GeV. The data are collected fully active scintillator detector in K2K long-baseline neutrino oscillation experiment. No evidence is observed, and an upper limit set on cross section ratio to total interaction at 90% confidence level. This first experimental charged region few

A new ultrasound array transducer with two different optimal frequencies designed for diagnosis and therapy integration in Doppler imaging-based transcranial sonothrombolysis is described. Previous studies have shown that respective around 0.5 2 MHz are suitable imaging. Because of the small acoustic window available exposure, it highly desirable both therapeutic diagnostic ultrasounds pass through same aperture high efficiency. To achieve such a dual-frequency transducer, we propose...
Abstract Background and study aims Although the number of resistant bacteria tends to increase with prolonged antimicrobial therapy, no studies have examined relationship between duration therapy in acute cholangitis. We hypothesized that short-term administration agents cholangitis would suppress bacterial resistance. Patients methods This was a single-center, retrospective, observational patients admitted January 2018 June 2020 who met following criteria: successful biliary drainage,...
Abstract Background and Aim The appropriate duration of antimicrobial therapy for acute cholangitis (AC) arising from multiple hilar biliary obstructions as opposed to simple obstruction in the extrahepatic bile duct has not been established. This study assessed efficacy treatments Tokyo Guidelines 2018 AC based on cause site obstruction. Methods single‐center retrospective involved patients with who underwent successful drainage completed a 7‐day or shorter treatment. Patients were...
Fifty-four adolescents from a middle school in the Los Angeles area completed two self-report measures that examined their experience of stress and identified stressors environment coping strategies they used to deal with these stressors. Gender differences were evident throughout study, girls indicating higher levels boys reporting different behavioral affective responses stress. Although sample as whole evidenced moderately low stress, school-related highest frequency, followed by siblings...

Short-term treatment of acute cholangitis is sufficient for cure compared with the standard duration. Whether this short-course antimicrobial therapy effective in patients positive blood cultures has not been fully investigated. This study assessed whether could achieve successful outcomes a three-day or shorter period, even culture.
Slab subsurface defects caused by mold powder entrapment tend to occur at high speed castig. Behavior of molten steel flow in continuous casting slab was investigated with water model experiments and tests actual caster.The results obtained are as follows:(1) the level fluctuation a has various frequency waves long period (0.1 0.2 Hz) related surface velocity steel.(2) reveal that is able be controlled optimization submerged nozzle desigh other parameters.(3) parameter expressing near narrow...
Low-frequency ultrasound, typically less than 1 MHz, is suitable for enhancing thrombolysis because it penetrates the cranium effectively. However, intracerebral hemorrhages after transcranial insonation in clinical trials at 300 Hz have been reported. In this study, acoustic bubble formation a standing wave with 617 kHz ultrasonic beam water surrounded by contoured piece of human was detected ultrasound B-mode imaging. This indirect evidence that standing-wave led to cavitational adverse...
Simultaneous enrichment broth (SEB) was developed for the single-enrichment simultaneous screening of six major food poisoning bacteria. After in SEB 18 h at 37°C, viable counts bacteria (Staphylococcus aureus, Salmonella spp., Escherichia coli O157:H7, Vibrio parahaemolyticus, Bacillus cereus, and Listeria monocytogenes) were sufficient 5' nuclease multiplex real-time PCR assay using existing primers probes. By labeling probes with three different fluorescent dyes, could be carried out 2...
For steel continuous castings, it is essential to control the molten velocity at meniscus, since closely related surface defects on resultant products. Argon gas supplied with into mold through a submerged entry nozzle prevent clogging. In this study, investigate influence of argon flow, numerical simulation was carried out for several casting speeds. The result higher speed similar case in which not used. lower indicates that as bubbles ascend near nozzle, they induce flow them. magnitude...
In a continuous casting process, it is essential to prevent the surface defects which are caused by entrapments of both mold powder and argon gas bubbles. It well known through experiments that decrease in molten steel flow velocity just under free one most effective methods for prevention entrapments. For this purpose, we have already employed electromagnetic force ElectroMagnetic Level Stabilizer (EMLS) system, applies low frequency alternating magnetic field moves from narrow face center...
To prevent the increase of resistant bacteria, it is important to minimize use antimicrobial agents. Studies have found that administration for ≤3 days after successful endoscopic retrograde cholangiopancreatography (ERCP) appropriate. Therefore, present study aimed verify if agents can be further shortened ≤2 ERCP. We divided 390 patients with mild and moderate cholangitis who underwent technically ERCP from January 2018 June 2020 had positive blood or bile cultures into two groups:...
