Firm Size, Source of Finance, and Growth - Evidence from China

Jun Du, Sourafel Girma

Nov 1, 2012 in International Journal of the Economics of Business
Using a comprehensive firm-level data set from China spanning the period 1998–2005, this study investigates the relationship between firm size, financing sources, and total factor productivity growth. Controlling for the endogeneity of financing sources, we find that firm size plays an important role in the way financial structure affects the growth process. Domestic bank loans are more effective...

A study on joint modeling and data augmentation of multi-modalities for audio-visual scene classification

Qing Wang, Chin-Hui Lee et 10 al.

Mar 7, 2022 in Arxiv
In this paper, we propose two techniques, namely joint modeling and data augmentation, to improve system performances for audio-visual scene classification (AVSC). We employ pre-trained networks trained only on image data sets to extract video embedding; whereas for audio embedding models, we decide to train them from scratch. We explore different neural network architectures for joint modeling to...

Spatial Transcriptomics Analysis Reveals that CCL17 and CCL22 are Robust Indicators of a Suppressive Immune Environment in Angioimmunoblastic T Cell Lymphoma (AITL).

Jun Du et 9 al.

Sep 29, 2022 in Frontiers in bioscience
T cell lymphoma is a complex and highly aggressive clinicopathological entity with a poor outcome. The angioimmunoblastic T-cell lymphoma (AITL) tumor immune microenvironment is poorly investigated. Here, to the best of our knowledge, spatial transcriptomics was applied for the first time to study AITL. Using this method, we observed that AITL was surrounded by cells bearing immune-suppressive mar...


Understanding the hydrological regime based on the runoff events in a mountainous catchment with seasonally frozen soil in the Qinghai‐Tibet Plateau

Pengfei Lin, Quanyan Tian et 5 al.

Sep 27, 2022 in Hydrological Processes
Seasonal thawing of frozen soil will significantly affect the hydrological regime, water storage capacity and ecosystem services in the future, which contributes to the uncertainty of regional water resources. However, based on the scale of runoff events, the mechanism of seasonal frozen soil thawing on the hydrological regime are still unclear. In this study, we systematically analysed the runof...

The effects of lipid-lowering therapy on coronary plaque regression: a systematic review and meta-analysis.

Yingrui Li, Qiang She et 10 al.

Apr 12, 2021 in Scientific reports
To assess the influence of lipid-lowering therapy on coronary plaque volume, and to identify the LDL and HDL targets for plaque regression to provide a comprehensive overview. The databases searched (from inception to 15 July 2020) to identify prospective studies investigating the impact of lipid-lowering therapy on coronary plaque volume and including quantitative measurement of plaque volume by ...

Qualitative and quantitative diagnosis of intramuscular hemangioma subtypes: Diagnostic performance comparison of ESWAN and conventional MRI.

Jun Du, Lixin Huang et 6 al.

Dec 17, 2021 in Acta radiologica
Preoperative identification of intramuscular hemangioma (IMH) subtypes (capillary hemangioma, cavernous hemangioma, and mixed hemangioma) is urgently necessary. Enhanced T2*-weighted angiography (ESWAN) is sensitive to vessels and metabolites and can be used to diagnose IMH subtypes. To compare the diagnostic performances of ESWAN and conventional magnetic resonance imaging (MRI) for qualitative a...

Effects of moisture content and tillage methods on creep properties of paddy soil.

Guoyang Liu, Dong Li et 5 al.

Jun 24, 2021 in PloS one
The rheological properties parameters of paddy soil affect the interaction between the tillage tools and soil, thus influencing the operation quality and power consumption. In order to study the effects of tillage methods and moisture content on the rheological properties parameters of paddy soil in the middle and lower reaches of the Yangtze River, uniaxial compression creep tests of paddy soils ...

Sorption, degradation and microbial toxicity of chemicals associated with hydraulic fracturing fluid and produced water in soils.

Rai S Kookana, Simon C Apte et 5 al.

Sep 15, 2022 in Environmental pollution
Spills of hydraulic fracturing (HF) fluids and of produced water during unconventional gas extraction operations may cause soil contamination. We studied the degradation and microbial toxicity of selected HF chemical components including two biocides (methylisothiozolinone- MIT, chloromethylisothiozolinone- CMIT), a gel-breaker aid (triethanolamine -TEA), and three geogenic chemicals (phenol, m-cr...

Identification of Key Genes and Pathways Associated with Hepatosplenic T-Cell Lymphoma (HSTCL) by Bioinformatics Analysis.

Jun Du, Wei-Wei Mou et 4 al.

May 1, 2021 in Clinical laboratory
Prognosis of Hepatosplenic T-Cell Lymphoma (HSTCL) is very poor, while the molecular mechanism of this disease has rarely been investigated and remains mysterious. The aim of the study is to screen differentially expressed genes (DEGs) of patients with HSTCL and normal controls, explore the pathogenesis, and provide guidance for the gene diagnosis and precise treatment of HSTCL. The genetic chip d...
