Abstract HO Puppis (HO Pup) was considered as a Be-star candidate based on its γ Cassiopeiae-type light curve, but lacked spectroscopic confirmation. Using distance measured from Gaia Data Release 2 and the spectral-energy-distribution fit broadband photometry, nature of Pup is ruled out. Furthermore, 28,700 photometric data points collected various time-domain surveys dedicated intensive-monit...

Using nickel electrode as dyeing electrode, sodium carbonate fixing alkali and anodic region region, cotton fabric was electrochemically dyed by reactive blue X-BR under external DC power supply. By comparing the rate, fixation polarization curve evenness of two methods, it can be concluded that electrochemical effect on dye is far better than traditional method.

We construct two pencils of bielliptic curves genus three and five. The first pencil is associated with a general abelian surface polarization type $(1,2)$. second related to the by an unramified double cover, Prym variety which canonically isomorphic Jacobian very curve two. Our results are obtained analyzing suitable elliptic fibrations on Kummer surfaces rational covers among them.

This paper presents a novel optical processing approach for exploring genome sequences built upon optical correlator for global alignment and extended DV-curve method for local alignment. To overcome the problem of traditional DV-curve method for presenting an accurate and simplified output, we propose HAWPOD, built upon DVcurve method, to analyze genome sequences in five steps: DNA coding, ali...

A two-step K(+)-Na+ and Ag(+)-Na+ ion-exchange technique is introduced to fabricate single-mode channel waveguides in BK7 glass for the telecom-wavelength region. The dependencies of insertion loss, polarization-dependent loss (PDL), end bending loss of curved waveguides on channel width, diffusion time, and annealing time are investigated. Results show that postannealing is a required process ...
