Effect of Low-Stress Fatigue on the Off-Crack-Plane Fracture Energy in Engineered Cementitious Composites

This paper presented an experimental study on the flexural properties of engineered cementitious composites (ECCs). The bending fatigue damage, residual deformation, and damage characteristics were investigated after a certain number of low stress levels in fatigue load. The composite fracture energy and fiber-bridging fracture energy were calculated by the J integral. It is observed that the number of cracks increased with the increment of stress levels, and most of the cracks were formed during the earlier stage of the dynamic test. The deformation capability decreased with the increment of stress levels while the reduction of the ultimate load was minor after the dynamic load. Furthermore, the strain-hardening phenomenon of the specimen enhanced initially and then weakened with the increment of stress levels. The residual equivalent yield strength became smaller with the increase of stress levels. Meanwhile, the trend was mild at low stress levels and then became steep at high stress levels

Modiff: Action-Conditioned 3D Motion Generation with Denoising Diffusion Probabilistic Models

Diffusion-based generative models have recently emerged as powerful solutions for high-quality synthesis in multiple domains. Leveraging the bidirectional Markov chains, diffusion probabilistic models generate samples by inferring the reversed Markov chain based on the learned distribution mapping at the forward diffusion process. In this work, we propose Modiff, a conditional paradigm that benefits from the denoising diffusion probabilistic model (DDPM) to tackle the problem of realistic and diverse action-conditioned 3D skeleton-based motion generation. We are a pioneering attempt that uses DDPM to synthesize a variable number of motion sequences conditioned on a categorical action. We evaluate our approach on the large-scale NTU RGB+D dataset and show improvements over state-of-the-art motion generation methods

Effect evaluation of agricultural water conservation policies in China

[Objective] The purpose of implementing active agricultural water conservation policies is to improve the utilization efficiency of water resources, alleviate the conflict between water resource supply and demand, and promote the sustainable development of agriculture. Correspondingly, active agricultural water conservation policies are an important way to achieve these goals. Exploring the effects of the policies is of great theoretical and practical significance for the scientific formulation and improvement of China’s agricultural water conservation policy. [Methods] Based on the agricultural water conservation policies promulgated by the Chinese government from 2011 to 2021, this study used the method of quantitative analysis of policy texts to measure the policy effectiveness in five dimensions: policy strength, objectives, measures, supervision, and feedback, and established a multiple regression model to assess the implementation effects of different policy tools. [Results] The results show that: (1) The overall effectiveness of the policies showed a fluctuating trend, but the average effectiveness of the policies in each year was generally low; (2) Among the five dimensions of policy effectiveness, there are many measures, but the intensity is low, the objectives are not specific enough, and the supervision and feedback are insufficient; (3) Among the policy tools, command-and-control and capacity-building policy tools had higher total and average effectiveness than economic-incentive and persuasive policy tools; (4) Each policy tool in the policy text had a lagged effect on the effective utilization coefficient of irrigation water, and the use of command-and-control and economic-incentive policy tools had a significant positive effect on the improvement of the effective utilization coefficient of irrigation water, while the role of persuasive and capacity-building policy tools needs to be further improved. [Conclusion] Therefore, first, China’s agricultural water conservation policies should be formulated in a way that strengthens top-level design and inter-sectoral coordination. Second, content effectiveness should be further improved and the specific content of the policy dimensions should be continuously enriched. Third, the four types of policy tools should be used in a synergistic manner to promote policies that produce good results
