We discuss the gravitational wave(GW) spectra predicted from the electroweak scalegenesis of the Higgs portal type with a large number of dark chiral flavors, which many flavor QCD would underlie and give the dynamical explanation of the negative Higgs portal coupling required to trigger the electroweak symmetry *** employ the linear-sigma model as the low-energy description of dark many flavor QCD and show that the model undergoes ultra-supercooling due to the produced strong first-order thermal phase transition along the(approximately realized) flat direction based on the Gildener-Weinberg mechanism. Passing through evaluation of the bubble nucleation/percolation, we address the reheating and relaxation processes, which are generically non-thermal and nonadiabatic. Parametrizing the reheating epoch in terms of the e-folding number, we propose proper formulae for the redshift effects on the GW frequencies and signal spectra. It then turns out that the ultra-supercooling predicted from the Higgs-portal scalegenesis generically yields none of GW signals with the frequencies as low as nano Hz,unless the released latent heat is transported into another sector other than reheating the universe. Instead, models of this class prefer to give the higher frequency signals and still keeps the future prospected detection sensitivity, like at LISA, BBO, and DECIGO, etc. We also find that with large flavors in the dark sector, the GW signals are made further smaller and the peak frequencies higher. Characteristic phenomenological consequences related to the multiple chiral scalars include the prediction of dark pions with the mass much less than Te V scale, which is also briefly addressed.

AIM: To evaluate the cost-utility of iStent inject;with cataract surgery vs cataract surgery alone in patients with mild-to-moderate primary open angle glaucoma(POAG) in the Japanese setting from a public payer’s ***: A Markov model was adapted to estimate the cost-utility of iStent inject;plus cataract surgery vs cataract surgery alone in one eye in patients with mild-tomoderate POAG over lifetime horizon from the perspective of Japanese public payer. Japanese sources were used for patients’ characteristics, clinical data, utility, and costs whenever available. Non-Japanese data were validated by Japanese clinical experts. RESULTS: In the probabilistic base case analysis, iStent inject;with cataract surgery was found to be cost-effective compared with cataract surgery alone over a lifetime horizon when using the ￥5 000 000/quality-adjusted life year(QALY)willingness-to-pay threshold. The incremental cost-utility ratio(ICUR) was estimated to be ￥1 430 647/QALY gained and the incremental cost-utility ratio(ICER) was estimated to be ￥12 845 154/blind eye avoided. iStent inject;with cataract surgery vs cataract surgery alone was found to increase costs(￥1 025 785 vs ￥933 759, respectively) but was more effective in increasing QALYs(12.80 vs 12.74) and avoiding blinded eyes(0.133 vs 0.141). The differences in costs were mainly driven by costs of primary surgery(￥279 903 vs ￥121 349). In the scenario analysis from a societal perspective, which included caregiver burden, iStent inject;with cataract surgery was found to dominate cataract surgery ***: The iStent inject;with cataract surgery is a cost-effective strategy over cataract surgery alone from the public payer’s perspective and cost-saving from the societal perspective in patients with mild-to-moderate POAG in Japan.

A recently found double-mode Cepheid with the shortest known period in our Galaxy and abnormal period ratio, V371 Per, is investigated by linear nonadiabatic pulsation models. V371 Per is likely to be crossing the instability strip for the first time, because the mass derived from pulsation models is larger than the evolution mass for the second or higher crossing objects. This result seems to support the conclusion obtained from spectroscopic observation. We also found that models with observed period and period ratio of V371 Per need to have mass and Teff in a narrow range which shifts as heavy element abundance Z changes. We have checked the agreement between Teffranges estimated observationally and derived from pulsation models using observational Z. We found that those ranges overlap marginally. We need more spectroscopic estimations of Teff and [Fe/H], and more photometric monitoring to estimate the evolutional period change for confirmation of our result.

In order to investigate the effect of transient needle opening on early stage of spray behavior, simultaneous measurements of velocity and size of droplet were conducted by a newly developed laser 2-focus velocimeter (L2F). The micro-scale probe of the L2F was consisted of two foci with a distance of 36μm. The tested nozzle had a single hole with a diameter of 0.2 mm. The measurements of injection pressure, needle lift, and crank angle were synchronized with the spray measurement by the L2F at the position 10 mm downstream from the nozzle exit. It has been clearly shown that the velocity and size of droplet increase with needle valve opening and that the probability density distribution of droplet size can be fitted to the Nukiyama-Tanasawa distribution under the transient needle opening condition.
