(abridged) We present a comprehensive study of sample 23 genuine radio-loud NLS1 galaxies which have the radio-loudness parameters greater than 100. The radio sources are ubiquitously compact. A significant fraction these objects show interesting to X-ray properties that unusual most previously known AGN, but reminiscent blazars. These include flat spectra, large amplitude flux and spectral variability, compact VLBI cores, very high brightness temperatures derived from enhanced optical...
The dependence of the long-term optical/UV variability on spectral and fundamental physical parameters for radio-quiet active galactic nuclei (AGNs) is investigated. multi-epoch repeated photometric scanning data in Stripe-82 region Sloan Digital Sky Survey (SDSS) are exploited two comparative AGN samples (mostly quasars) selected therein, a broad-line Seyfert\,1 (BLS1) type sample narrow-line (NLS1) within redshifts 0.3--0.8. Their derived from SDSS spectroscopic data. It found that...
Selective laser melting (SLM) has attracted increasing attention all over the world. As an important parameter, hatch spacing, which is distance between scan lines, however, still needs a more systematic study. In this paper, relationship spacing and mechanical properties, including microhardness, wear resistance, porous density, was studied. The testing results revealed that when decreased, overlapping rate increased resulted in increase convection molten pool. It led to formation of pores...
Designing high-performance conductive polymer composites with three-dimensional (3D) porous structures for pressure sensors is still challenging, limiting their applications in various settings. Herein, a facile route fabricating 3D microporous MXene/polyurethane (MXene/PU) composite gels developed via template strategy. The iron foam acts as to provide framework the network structure, while PU and MXene form robust organic/inorganic through inter- intramolecular hydrogen bonding...
We report the discovery of a luminous ultra-soft X-ray excess in radio-loud narrow-line Seyfert 1 galaxy, RX J1633+4718, from archival ROSAT observations. The thermal temperature this emission, when fitted with blackbody, is as low 32.5+8.0−6.0 eV. This remarkable contrast to canonical temperatures ∼0.1–0.2 keV found hitherto for soft active galactic nuclei (AGNs) and interestingly close maximum predicted postulated accretion disk object. If emission indeed blackbody nature, derived...
Abstract. Using 14 years (2007–2020) of data from passive (MODIS/Aqua) and active (CALIOP/CALIPSO) satellite measurements over China, we investigate (1) the temporal spatial variation aerosol properties Beijing–Tianjin–Hebei (BTH) region, Yangtze River Delta (YRD), Pearl (PRD) (2) vertical distribution types extinction coefficients for different optical depth (AOD) meteorological conditions. The results show patterns seasonal variations AOD three regions. Annual time series reveal occurrence...
ABSTRACT Background: Natural ecosystems provide necessary services for human beings, including ecosystem service values (ESVs) and socioeconomic (SSVs). The value orientations of ESVs SSVs are mainly related to people’s interaction with nature. This study reclassified greenspace from a perspective exposed non-exposed based on the level by people greenspace. We applied an expert questionnaire survey forestland, grassland, wetland, water bodies, quantitatively compared between in China....
In this paper, the possibility of retreated lithium slag (RTLS) with a high content alkali, sulfate and fluoride as partial replacement for fly ash (FA) to produce autoclaved aerated concrete (AAC) was investigated. The influence RTLS dosage on AAC performance were examined. composition microstructure hydrates well RTLS-FA-based compositions determined by XRD, FTIR, TG-DSC SEM. results illustrated that incorporation changed crystal structure tobermorite. With increased contents, morphology...
Video traffic is becoming the dominant form of over mobile networks, challenging ongoing standardization and deployment Next generation networks (4G). Currently, as mainstream design evolution to 4G, LTE provide high data-rate communication tunnels between users Internet. However, this generic tunneling introduces at least 3 external hops for any request network, which results in latency well operating expense, especially video with bandwidth requirement. In work, we propose EPCache, a novel...
Compared with traditional timber boards, timber–concrete composite (TCC) boards demonstrate a higher rigidity and bearing capacity, improved vibration, better behavior under seismic conditions. However, they become charred when exposed to fire due the combustibility of timber, safety this material is considered essential. In research, 60 min exposure tests residual load-carrying capacity following were carried out on three full-scale two which covered an innovative form gypsum board...
