ABSTRACT We present the analysis of SN 2020wnt, an unusual hydrogen-poor superluminous supernova (SLSN-I), at a redshift 0.032. The light curves 2020wnt are characterized by early bump lasting ∼5 d, followed bright main peak. reaches peak absolute magnitude M$_{r}^{\rm max}=-20.52\pm 0.03$ mag ∼77.5 d from explosion. This is lower end luminosity distribution SLSNe-I, but rise-time one longest reported to date. Unlike other spectra do not show O ii, strong lines C ii and Si detected....
A superconducting 166.6 MHz quarter-wave beta=1 cavity was recently proposed for the High Energy Photon Source (HEPS), a 6 GeV kilometer-scale light source. Four cavities will be used main acceleration in newly planned on-axis beam injection scheme realized by double-frequency RF system. The fundamental frequency, MHz, dictated fast kicker technology and preference of using 499.8 SC as third harmonic. Each operated at 4.2 K providing 1.2 MV accelerating voltage 150 kW power to electron beam....

Concentrations of organic carbon, carbon isotopes ( 13 C and 14 C), atmospheric 10 Be in soil, situ bedrock weathering rock were determined a study profile grassland slope at the Heshan Hilly Land Interdisciplinary Experimental Station, Chinese Academy Sciences, Guangdong Province, China. A good linear relationship between depth apparent age demonstrates that process accumulation matter are relatively stable. Both results show about 34% soil has been eroded during past 3800 yr. The for...
We demonstrated a stable passively Q-switched fiber laser operation at 1531.57 nm using double-transition metal MAX phase TiNbAlC saturable absorber. The prepared absorber’s modulation depth, saturation intensity, and non-saturation loss are 1.75%, 0.089 MW/cm2, 32.81%, respectively. Using the absorber within an erbium-doped ring cavity, pulses with central wavelength of nm, 3-dB bandwidth 1.43 acquired. minimum pulse duration maximum single energy 3.18 μs 51.56 nJ, Furthermore, repetition...
Sino-Russian natural gas cooperation has an important impact on trade in both Russia and China. Based the Herfindahl-Hirschman Index (HHI), this paper established a import export security evaluation system to scientifically assess with respect structure situation under influence of different factors. The research shows: diversification imports China gradually increased. China's from are rise; When accounting for potential importing countries, HHIC-PE reveals wavy upward trend after falling...
<h3>Introduction</h3> We have created two novel poxviral vector-based HIV vaccines that transiently inhibit IL-4/IL-13 activity at the vaccination site (murine IL-13Rα2 or IL-4R antagonist) induce high avidity HIV-specific CD8 T cells with better protective efficacy. Compared to adjuvanted vaccine, antagonist vaccine induced not only but also excellent gag-specific IgG1 and IgG2a antibody differentiation similar what has been observed in elite controllers. In this study, how differentially...
Abstract A cryogenic test platform was conceived and designed with a variable temperature from 1.8K to 300K accomplish the research of seal performance, main object this is capacity flange structure in superfluid helium condition. This mainly includes cryostat, set vacuum pumps, sealed chamber, physical property leak detection system, acquisition control systems. The cold source supplied by 1.5K helium, which will be obtained combining throttling decompression. Mechanical designs detailed...
