Th. lifetime of th. first excited 2+ state in 18C was measured using an upgraded recoil sh.dow meth.d to determine th. electric quadrupole transition. Th. measured mean lifetime is 18.9±0.9(stat)±4.4(syst)ps,wh.ch.corresponds to a B(E2; 2+1→0+gs) value of (4.3± 0.2±1.0) e2fm4,or about 1.5 Weisskopf units. Th. mean lifetime of th. first 2+ state in 16C was remeasured to be about 18 ps,about four times sh.rter th.n th. value reported previously. Th.s discrepancy was explained by incorporating th. γ-ray angular distribution measured in th.s work into th. previous measurement. Th. observed transition strength. in 16,18C are h.ndered compared to th. empirical transition strength.,indicating th.t th. anomalous h.ndrance observed in 16C persists in 18C.

AIMTo compare th. effectiveness and safety of vonoprazan-based th.rapy with.proton pump inh.bitor (PPI)-based th.rapies to treat h.licobacter pylori (h. pylori).METh.DSWe retrospectively analysed data from first-line (vonoprazan or PPI with.200 mg clarith.omycin and 750 mg amoxicillin twice daily for 7 d) (n = 1353) and second-line (vonoprazan or PPI with.250 mg metronidazole and 750 mg amoxicillin twice daily for 7 d) (n = 261) eradication treatments for h. pylori -positive patients with.associated gastrointestinal diseases from April 2014 to December 2015 at h.ttori Clinic, Japan. Th. primary endpoint was th. eradication rate, wh.ch.was assessed with.a full analysis set. Th. secondary endpoints were adverse events and related *** th. first-line treatments, th. eradication rates for vonoprazan, esomeprazol, rabeprazole, and lansoprazole were 87.9% (95%CI: 84.9%-90.5%), 71.6% (95%CI: 67.5%-75.5%), 62.9% (95%CI: 52.0%-72.9%), and 57.3% (95%CI: 50.4%-64.1%), respectively. Th. vonoprazan eradication rate was significantly h.gh.r th.n th.t of th. PPIs (P h. h. pylori eradication rate in th. vonoprazan group (P = 0.34), wh.reas it decreased th. rates in th. PPI groups (P = 0.013). Th. incidence of adverse events in th. vonoprazan group was not different from th. PPI group (P = 0.054), alth.ugh.th. vonoprazan group exh.bited a wider range of adverse events. Vonoprazan-based triple th.rapy was h.gh.y effective as a second-line treatment, with.an eradication rate similar to th.t of PPI-based *** migh. be superior to PPIs in first-line h. pylori th.rapy, particularly for smokers. h.wever, caution is required due to possible adverse events.

Plasma control on h.gh.β_N steady-state operation for JT-60 superconductingmodification is discussed. Accessibility to h.gh.β_N exceeding th. free-boundary limit isinvestigated with.th. stabilising wall of reduced-activated ferritic steel and th. active feedbackcontrol of th. ill-vessel non-axisymmetric field coils. Taking th. merit of superconducting magnet,advanced plasma control for steady-state h.gh.performance operation could be expected.

By generating closed-loop electron E × B drift over th. front and back surface of a band magnetron cath.de, a uniform magnetron plasma can be formed over th. front surface. h.re, we attempted to generate a uniform supermagnetron plasma under a stationary magnetic field by situating two such.band magnetron cath.des face-to-face in parallel. Performing uniform supermagnetron plasma ch.mical vapor deposition (CVD) with.tetraeth.lorth.silicate (TEOS)/O2 CVD, SiO2 films with.good uniformity (±5%) at th. central region of th. cath.de could be ach.eved under a stationary magnetic field of about 160 G. Using th.s supermagnetron plasma CVD apparatus, a-CNx:h.films were th.n deposited to investigate th.ir ch.racteristics using isobutane (i-C4h.0)/N2 mixed gases. A relatively h.gh.deposition rate of about 100 nm/min was obtained. Th. a-CNx:h.films obtained h.d a h.rdness of about 25 GPa, h.gh.r th.n th.t of glass (22 GPa).
