Impact of Public Environmental Concerns on the Digital Transformation of Heavily Polluting Enterprises.

China is currently facing the arduous tasks of energy conservation, emission reduction and structural transformation, making it of great significance to study the digital transformation of heavily polluting enterprises. As an important informal regulatory system, public environmental concerns affect corporate environmental behavior by increasing external environmental pressure. This study uses the data of listed companies in China's heavily polluting industries from 2012 to 2020 and Baidu Index data to analyze how public environmental concerns affect the digital transformation of heavily polluting enterprises.

Optimal timing of preoperative intravitreal anti-VEGF injection for proliferative diabetic retinopathy patients.

Aim: To analyze concentrations of vascular endothelial growth factor (VEGF) and fibrosis-related factors in vitreous fluid of proliferative diabetic retinopathy (PDR) patients pre-treated with intravitreal anti-VEGF injections (IVI) at different time periods prior to pars plana vitrectomy (PPV), and their correlation with the degree of vitreoretinal fibrosis and explore the optimal timing of preoperative IVI.

Methods: The prospective case-control study from January 2019 to July 2020 included 31 eyes with PDR-related complications (PDR group) and 21 eyes with non-diabetic ocular disease (control group) requiring PPV. PDR eyes were divided into four groups based on timing of PPV: 3d after IVI (3-day group); 5d after IVI (5-day group); 7 or more days after IVI (≥7-day group); and no IVI.

The influence of environmental cognition on green consumption behavior.

With rising consumption and environmental problems, there is an increasing need for green consumption. From a micro perspective, the influence of environmental cognition on consumers' green consumption behaviors and the related mechanisms are examined through multilayer linear analysis and 2010 China General Social Survey (CGSS) microdata with the theory of planned behavior (TPB) as the model framework. The study shows that (1) environmental cognition positively influences attitudes toward green consumption, green consumption subjective norms, and green consumption perceived behavioral control, which leads to increased intentions to engage in green consumption and actual green consumption behaviors.

A Special Ancient Bronze Sword and Its Possible Manufacturing Technique from Materials Science Analysis.

In this study, it was found that an ancient bronze sword had special microstructures, i.e., a tin (Sn)-rich layer (Sn: 38.

A retrospective study assessing the factors associated with visual outcome in retinal vein occlusion patients after anti-VEGF therapy.

Background: Retinal vein occlusion (RVO) is one of the most frequent retinal vascular diseases. In this study, we aimed to investigate the predictive factors of visual outcome for RVO patients who underwent anti-vascular endothelial growth factor (VEGF) therapy.

Methods: RVO patients who underwent anti-VEGF treatment were recruited in this study from January 2018 to June 2020.

[Study on testing methods of the elastic nature for equivalent material of human skin].

To the specificity of equivalent material of human skin mechanical properties, the static-load pressing method for testing the elastic nature of the equivalent material of human skin is proposed, and the designs experimental set for the test is designed. The result show that the method is correct and feasible.

Investigating testing elasticity of equivalent material for human skin.

To the elasticity specificity of equivalent materials with human skin's nature, the static-load pressing method for testing the elastic nature of the equivalent material for human skin is approached in this paper, and the experimental set for the testing process is designed. And it is very important and useful to biomedicine science and engineering that evaluating correctly the mechanical property of the equivalent materials with human skin's nature.
