Recent years have witnessed the popularity of online peer-to-peer lending, which allows individuals to borrow from and lend each other on an Internet-based platform. Using data a large P2P platform in China, this article explores factors that determine default risk based demographic characteristics borrowers. Moreover, we propose credit evaluation model, can quantify loan. Empirical results reveal gender, age, marital status, educational level, working years, company size, monthly payment,...
Abstract Galaxy morphology in stellar light can be described by a series of “non-parametric” or “morphometric” parameters, such as concentrationasymmetry-smoothness, Gini, M 20, and Sersic fit. These parameters applied to column density maps atomic hydrogen (H i ). The H distribution is susceptible perturbations environmental effects, e.g. inter-galactic medium pressure tidal interactions. Therefore, potentially identify galaxies undergoing ram-pressure stripping We explore three fields...
With a new joint-deconvolution pipeline, we combine the single-dish and interferometric atomic hydrogen (HI) data of M51 observed by FAST (FEASTS program) VLA (THINGS). The product cube has typical line width $13\,\text{km}\,\text{s}^{-1}$ $2\sigma$ line-of-sight (LOS) sensitivity HI column density $N_\text{HI}\sim3.2\times10^{18}\,\text{cm}^{-2}$ at spatial resolution ${\sim}18''$ (${\sim}0.7\,\text{kpc}$). Among HI-detected LOSs extending to ${\sim}50\,\text{kpc}$, ${\sim}89\%$ consist...
Lower back pain is a common problem in middle-aged and elderly people, intervertebral disc degeneration (IVDD) often the main cause. The present study aimed to explore effects of dimethyl fumarate (DMF) on inflammation oxidative stress disc. C57/BL6 mice were used construct an IVDD model by tail suspension daily intraperitoneal injections 10 mg/kg DMF administered analyze IVDD. In addition, human nucleus pulposus (NP) cells cultured stimulated with recombinant IL-1β examine NP cells....
The telecommunications industry has been undergoing tremendous technological changes, and owning to continuous advancement, it maintained sustained prosperity development. In this paper, the interplay between technology, market government in is discussed briefly, then we introduce technology into traditional SCP (Structure - Conduct Performance) paradigm develop an analysis framework called TG-M(SCP) (Technology Government Market Performance)). Based on framework, present spiral co-evolution...
We update the HI surface density measurements for a subset of 17 THINGS galaxies by dealing with short-spacing problem original VLA images. It is same sample that Bigiel et al. (2010) used to study relation between densities and star formation rate in galaxy outer disks, which are beyond optical radius r25. For ten galaxies, based on combining images taken single-dish FAST FEASTS program. The median increment disks 0.15 0.4 dex at given new density. Several change significantly shape radial...
Combining new HI data from a synergetic survey of ASKAP WALLABY and FAST with the ALFALFA data, we study effect ram pressure tidal interactions in NGC 4636 group. We develop two parameters to quantify disentangle these effects on gas stripping HI-bearing galaxies: strength external forces at optical-disk edge, outside-in extents HI-disk stripping. find that is widespread this group, affecting 80% HI-detected non-merging galaxies, 41% are experiencing both types Among galaxies effects,...
Abstract Since the Reform and Opening-up in 1978, China has experienced a huge sustainable growth of gross domestic product (GDP) an incredible development Information Communication Technology (ICT). This study aims to utilize input-output (I-O) approach explore role ICT Chinese national economy. Specifically, we employ static I-O framework, analyze three topics its application: inter-industry linkage effect, production inducing supply shortage effect. We pay particular attention...
Summary In the network neutrality debate, safeguarding innovations in digital economy is an important concern. However, impacts of regulation on technological innovation telecommunications have not been well understood, especially with mathematical model. This study first briefly discusses significant role telecommunications. Then, we adopt a stylized two‐sided model (Internet broadband provider connect two sides Internet, content providers and end customers) use two‐stage game theory to...
We use the single-dish radio telescope FAST to map HI in tidally interacting NGC 4631 group with a resolution of 3.24$'$ (7 kpc), reaching 5-$σ$ column density limit $10^{17.9}$ cm$^{-2}$ assuming line width 20 km s$^{-1}$. Taking existing interferometric image from HALOGAS project WSRT as reference, we are able identify and characterize significant excess large-scale, low-density, diffuse group. This extends for more than 120 kpc across, accounts one fourth total detected by around galaxy...
After the development of more than 100 years, world’s telecommunications industry has become an important basic industry, a reflection national competitiveness and innovation. Compared with level telecom in most countries world, China’s technology is lower, regulatory system relatively backward, comprehensive lower. In this paper, based on data 132 countries, fixed effect least squares model established relationship between technological innovation government regulation analyzed empirically....
The fast growing telecommunications industry in China has been experiencing dramatic technological change and substantial productivity growth. actual growth pattern the sector, however, need to be empirically examined. In this paper, using input output data at provincial level, we employ DEA-based Malmquist index estimate change, relative efficiency China's for period spanning years from 2011 2015. results show that based on our sample, improved by 22.9% per annum, which was exclusively due...
