INTRODUCTION,Drug addiction is a chronic and recurrent encephalopathy characterised by impulsive behaviour,spiritual cravings,psychological distortion and physical damage!'According to the role of molecular biology mechanisms on the central nervous system,addictive substances can be classified as inhibitors(eg,opioids,etc),stimulants(eg,methamphetamine(MA),nicotine,cocaine,etc)and hallucinogens(eg,cannabis,etc).As published by the World Drug Report 2022,over284million individualsaged 15-64 worldwide have reportedly abused drugs in the past 12 months,emphasising the international challenge of effective detox treatment.

目的研究一种铜基纳米材料的抗菌性能及其抗菌效果的影响因素,探讨其实际应用的可能性。方法采用贴膜法测试该铜基纳米材料对金黄色葡萄球菌和大肠埃希菌的抗菌性能,研究有机干扰物、温湿度和化学中和等条件对该材料抗菌性能的影响。结果在温度37℃、相对湿度90%的条件下作用1 h,该铜基纳米材料表面金黄色葡萄球菌和大肠埃希菌的杀灭对数值分别>6.71和>6.37。以金黄色葡萄球菌作为指示菌,加入3%牛血清白蛋白,对其杀灭对数值下降至5.87;在降低温度(20℃、90%)和湿度(37℃、30%)的条件下,对其杀灭对数值分别下降至2.78和3.59;使用D/E中和剂后,对其杀灭对数值下降至4.15。结论该铜基纳米材料具有较好的抗菌性能,但有机物和环境温湿度变化均会影响其抗菌效果,评价时使用中和剂也会直接影响检测结果。

Dear editor,In this work,we study the notion of attributebased non-interactive key-exchange(ABNIKE).As a natural extension of the notions of non-interactive key-exchange(NIKE)[1,2]and identity-based non-interactive key-exchange(IBNIKE)[3,4],ABNIKE allows users to noninteractively agree on a common shared *** from attribute-based encryption[5],we divide ABNIKE into two forms:key-policy ABNIKE(KP-ABNIKE)and shared-key-policy

Specially designed wire-drawing equipment with multiple electropulse generator was introduced. The influences of multiple electropulses processing on the microstructure and properties of the hardened steel wire were investigated. Samples treated by direct current under the same current density as that in multiple electropulses processing were carried out for contrast analysis. The results show that the optimized parameters of multiple electropulses processing will be facilitated to increase the nucleation rate and slow down the growth rate of recrystallized grains. Consequently, massive superfine grains of micro and sub-micro scale could be found in the steel wire. Thereby, the elongation was significantly enhanced with a relatively small strength reduction in comparison with as-received cold-drawing steel wires. Outstanding mechanical properties of steel wire were obtained.

Internet of things(IoT) can provide the function of product traceability for industrial systems. Emerging blockchain technology can solve the problem that the current industrial Internet of things(IIoT) system lacks unified product data sharing services. Blockchain technology based on the directed acyclic graph(DAG) structure is more suitable for high concurrency environments. But due to its distributed architecture foundation, direct storage of product data will cause authentication problems in data management. In response, IIoT based on DAG blockchain is proposed in this paper, which can provide efficient data management for product data stored on DAG blockchain, and an authentication scheme suitable for this structure is given. The security of the scheme is based on a discrete-logarithm-based assumption put forth by Lysyanskaya, Rivest, Sahai and Wolf(LRSW) who also show that it holds for generic groups. The sequential aggregation signature scheme is more secure and efficient, and the new scheme is safe in theory and it is more efficient in engineering.
