Comprehensive Utilization Policies of Crop Straw at Home and Abroad and Its Implications for Xinjiang

This paper summarizes crop straw utilization policies at abroad from the aspects of investment support policies, tax revenue and unsecured loan policies, and reviewed China’s crop straw utilization policies from the aspects of technical training, project subsidies, straw collection, storage and transportation system construction and socialized service system construction. Combined with the actual situation of Xinjiang, this paper puts forward policy formulation suggestions on crop straw comprehensive utilization

Effect of Degradable Plastic Film Mulching on Cotton Yield in Yuli County

Nine kinds of biodegradable plastic film and one kind of conventional PE film are used to conduct experiment in the field, and study the effect of degradable plastic film on cotton yield. The results show that there is no difference in cotton yield between Treatment II, III, and ordinary PE film, and other kinds of degradable plastic film significantly reduce yield, with yield reduction of 6.5%-16.7%. The yield differences among treatments are mainly affected by the number of plants harvested

Application and Residue Pollution of Mulching Films in Xinjiang

In order to study current situation of application, recycling and residue pollution of mulching films in Xinjiang, and accurately grasp pollution degree of residue of mulching films, this paper made an empirical analysis on residue of mulching films in 31 typical counties and cities in Xinjiang. Results indicate that (i) use of mulching films in Xinjiang is wide and there is great difference in use and residue recycling between cities and counties. Planting area and planting structure jointly influence use of mulching films, and the use of mulching films is significantly correlated with recycling of mulching films, but not correlated with recycling rate of mulching films. (ii) There are significant differences in distribution of residue of mulching films, highest in North Xinjiang and South Xinjiang, followed by East Xinjiang, and the lowest in West Xinjiang. (iii) There are significant differences in distribution of residue of mulching films between different crop fields. Residue of mulching films in cotton field is the key problem of pollution

Oscillatory Neural Network-Based Ising Machine Using 2D Memristors

Neural networks are increasingly used to solve optimization problems in various fields, including operations research, design automation, and gene sequencing. However, these networks face challenges due to the nondeterministic polynomial time (NP)-hard issue, which results in exponentially increasing computational complexity as the problem size grows. Conventional digital hardware struggles with the von Neumann bottleneck, the slowdown of Moore’s law, and the complexity arising from heterogeneous system design. Two-dimensional (2D) memristors offer a potential solution to these hardware challenges, with their in-memory computing, decent scalability, and rich dynamic behaviors. In this study, we explore the use of nonvolatile 2D memristors to emulate synapses in a discrete-time Hopfield neural network, enabling the network to solve continuous optimization problems, like finding the minimum value of a quadratic polynomial, and tackle combinatorial optimization problems like Max-Cut. Additionally, we coupled volatile memristor-based oscillators with nonvolatile memristor synapses to create an oscillatory neural network-based Ising machine, a continuous-time analog dynamic system capable of solving combinatorial optimization problems including Max-Cut and map coloring through phase synchronization. Our findings demonstrate that 2D memristors have the potential to significantly enhance the efficiency, compactness, and homogeneity of integrated Ising machines, which is useful for future advances in neural networks for optimization problems

How myosin organization of the actin cytoskeleton contributes to the cancer phenotype

The human genome contains 39 genes that encode myosin heavy chains, classified on the basis of their sequence similarity into 12 classes. Most cells express at least 12 different genes, from at least 8 different classes, which are typically composed of several class 1 genes, at least one class 2 gene and classes 5, 6, 9, 10, 18 and 19. Although the different myosin isoforms all have specific and non-overlapping roles in the cell, in combination they all contribute to the organization of the actin cytoskeleton, and the shape and phenotype of the cell. Over (or under) expression of these different myosin isoforms can have strong effects on actin organization, cell shape and contribute to the cancer phenotype as discussed in this review
