Abstract Aim Previous studies have shown the important relationships between Enterococcus faecalis and Candida albicans in post‐treatment endodontic disease (PTED). However, fungal–bacterial interactions their possible functional routes are less understood. In this study, we investigated effect of extracellular vesicles (EVs) derived from C. on E. growth pathogenicity. Methodology EVs were isolated a yeast nitrogen base (YNB) medium, morphology, size distribution, protein concentration...

Abstract This study investigates the information content of Management Discussion and Analysis ( MD &A) reports listed Chinese companies. We develop a word dictionary measure tones &As. Our results indicate that tone is positively associated with future earnings particularly useful when firm's prospect uncertain, accounting difficult to understand, or board monitoring strong. Further analyses show also predicts cash flow, sales growth, market reactions, analysts’ revisions,...

Intercropping is widely used in agricultural production due to its capability of raising land productivity and providing an opportunity achieve sustainable intensification agriculture. In this study, soil samples from 10 20 cm depth intercropping Pinto peanut litchi orchard monoculture mode were established determine attributes, enzyme activities, as well the effect on bacterial diversity. On basis, 16S rRNA V4-V5 region communities litchi/Pinto (LP) (CK) was detected by Illumina MiSeq...

From the perspective of corporate social responsibility (CSR) e-commerce platform, this paper investigates choice platform for wholesale sales, agency and hybrid sales modes when manufacturer has both an offline retail channel channel. Taking as dominant player considering factors such potential market size consumers’ sensitivity to CSR input level, cost coefficient, we constructed a Stackelberg game model under modes. We explored impact platform’s behavior on its well members supply chain....

Abstract While close distance to trading partners is often viewed as beneficial business operations, our study reveals a potential downside. We show that firm's geographical proximity its major positively correlated with audit fees, which can be explained by an opportunistic narrative: interactions within the supply chain facilitate misconduct, increasing auditors' engagement risk and concerns. Further analyses suggest mid‐ lower‐level employees, rather than top management, are more likely...

Risk information disclosed in annual reports may have positive impacts on analyst earnings forecast by improving quality, or negative increasing the risk perception of analysts. In this paper, we quantify disclosures using textual analysis, and examine impact accuracy. The results at firm-level show that (1) collectively accuracy increases with more disclosures; (2) effect is significant group non-SOEs, higher auditing better corporate governance, suggesting good internal external governance...

In this paper a Modified Three-District Model was introduced to study the marine medium-sized horizontal LNG storage tank.The cryogenic tank evaporation rate and lossless time with liquid nitrogen were experimented.The maximum error of pressure change obtained by modified experiment observed be only about 4.7%.So applicability reliability model for have been verified.Furthermore, based on an effective volume 250 m 3 in dual fuel-filled barge, forecast analysis under different conditions...

We develop a model to illustrate that controlling shareholders choose the level of investor protection maximizes their own interests. Controlling in companies with complicated control structures can easily extract private benefits and are thus reluctant enhance which would necessitate increased transparency. In contrast, valuable growth opportunities willing improve so they benefit from value resulting lower cost capital. test this prediction using firm-level data China. The results show...

How supply chain information can help a company is given considerable attention by academic and practical circles. As boosting in the Chinese capital market, there higher demand for loans. Our study uses 2007–2017 listed data to whether about major customers affecting company's reliance on collateral loan, which reflects incremental value banks assessing credit risks. The results found that detailed customer disclosed send positive signals bank of high-quality environment reduce its...

Porcine epidemic diarrhea virus (PEDV), an enteric coronavirus, has become the major causative agent of acute gastroenteritis in piglets since 2010 China. Given a raised interest mutation and recombination viral genomes, genetic antigenic characteristics PEDV should be continuously investigated. In current study, 91 complete spike (S) gene sequences were obtained from positive samples collected from17 provinces China March 2020 to 2021. A phylogenetic analysis showed that 92.3% (84 out 91)...

AimThe current study evaluated the antibacterial activity of a newly developed quaternary ammonium polymethacrylate (QAPM)-containing bioactive glasses (BGs) via two-step method by our group, namely BGs-HAEMB, and explored its cytotoxicity biocompatibility.Methodology: The effects BGs-HAEMB against planktonic bacteria, bacterial biofilm formation, experimental root canal biofilms persistent pathogens (Enterococcus faecalis, Streptococcus sanguis Porphyromonas endodontalis) associated with...

Product accumulate (PA) codes are a class of with good performance, low complexity, regular structure and flexible rate adaptation, which include PA-I PA-II codes. In this paper the differences between low-density parity-check (LDPC) on their error-correcting performances investigated over AWGN channel. The simulation results show that outperform LDPC long codeword length for rates above 1/2. It could be foreseen choice in future digital communication systems

Jackfruit (Artocarpus heterophyllus) is an important tropical commercial fruit crop grown in Hainan province, China. In recent years, severe jackfruit bronzing disease has been found 11 cities and counties Hainan. On average, 80% of trees a orchard are affected once detected. The characterized by yellow-orange to reddish discoloration the pulp rags infected (Hernández-Morales et al. 2017). reported previously Philippines (Gapasin 2012), Malaysia (Zulperi 2017), Mexico Diseased samples 'Tai...

In this letter, a framework of punctured rate-compatible multi-edge-type LDPC (RC-MET-LDPC) codes with short block length is presented. The simple form traditional puncturing algorithms based on grouping and sorting (GS) algorithm can be applied for obtaining rate compatibility because the structure advantage MET-LDPC over conventional codes. simulation results show that RCMET-LDPC not only outperform irregular efficiently-encodable (E <sup xmlns:mml="http://www.w3.org/1998/Math/MathML"...

A new scheme of rate-compatible (RC) irregular repeat accumulate (IRA) codes is proposed which can be encoded and decoded using a single encoder-decoder pair provide good performance across wide range code rates. Conventional strategies generally start from low-rate mother puncture the rate up. Considering that initial transmissions (and hence higher-rate codes) are most important, we propose to high-rate "split" down. Rather than do it gradually in greedy manner, design one-shot-split...
