To date, there has been no report on fast-charging and Ahlevel sodium-ion batteries (SIBs) by utilizing thick hard carbon anodes that demonstrate prolonged cycling life and high areal capacity at high rates. Further, the relationship among the complex structure of hard carbon, storage mechanism, and fastcharging performance in alkali-metal ion batteries has been a subject of ongoing debate [1,2].

The wireless sensor network （WSN） has been widely used in various fields, but it still remains in the preliminary discovery and research phase with a lack of various related mature technologies. Traditional encryption schemes are not suitable for wireless sensor networks due to intrinsic features of the nodes such as low energy, limited computation capability, and lack of storage resources. In this paper, we present a novel block encryption scheme based on the integer discretization of a chaotic map, the Feistel network structure, and an S-box. The novel scheme is fast, secure, has low resource consumption and is suitable for wireless sensor network node encryption schemes. The experimental tests are carried out with detailed analysis, showing that the novel block algorithm has a large key space, very good diffusion and disruptive performances, a strict avalanche effect, excellent statistical balance, and fast encryption speed. These features enable the encryption scheme to pass the SP800-22 test. Meanwhile, the analysis and the testing of speed, time, and storage space on the simulator platform show that this new encryption scheme is well able to hide data information in wireless sensor networks.

BACKGROUND Primary hepatic leiomyosarcoma is rare and reported sporadically, with less than40 such cases have been reported in the English-language literature. Although it is reported to be associated with acquired immune deficiency syndrome, EpsteinBarr virus infection, Hodgkin's lymphoma, immunosuppression after organ transplantation, and hepatitis C virus-related liver cirrhosis, the precise steps leading to leiomyosarcoma have not been fully identified. Therapeutic strategies include liver wedge resection or lobectomy, chemotherapy, radiotherapy and liver transplantation; however, the prognosis of primary hepatic leiomyosarcoma is *** SUMMARY We describe here the first case of primary hepatic leiomyosarcoma successfully treated by transcatheter arterial chemoembolization(TACE). The patient was a 68-year-old woman who presented with right upper quadrant pain and weight loss over the past 5 wk before admission. Abdominal computed tomography(commonly known as CT) and ultrasonography showed a mixed echoic mass measuring about 10 cm × 7 cm occupying the right lobe of the liver. Exploratory laparotomy was performed 1 wk after admission. The tumor was unresectable and biopsy was performed. Based on rapid frozen-section and histopathological examination, a final diagnosis of primary hepatic leiomyosarcoma was established. TACE was performed 2 wk later. The postoperative course was uneventful and the patient was discharged on day 7 after the operation. Contrastenhanced CT showed that the tumor significantly shrunk with satisfactory lipiodol deposition. The patient has been followed up for 82 mo until now, and no progressive enlargement of the tumor or distal metastasis was *** TACE is a safe and effective treatment for primary hepatic leiomyosarcoma. The therapeutic effect of TACE combined with surgical resection should be further assessed.

We report a novel cyano migration-mediated radical-polar crossover process, whereby both the sulfonylcyanation of aliphatic alkenes and the formation of cyclopropanes are concurrently achieved. This transformation yields a diverse array of multisubstituted cyclopropanes under mild photocatalytic conditions. Mechanistic studies elucidate that the reaction proceeds via intramolecular nucleophilic substitution, leading to the formation of the cyclopropane derivatives.

在氢环境下,氢原子会吸附在金属材料表面.随着时间推移,氢原子会渗透进入金属内部占据空隙位置.氢原子的聚集会导致应力集中,最终进一步影响材料的力学行为.本文通过分子动力学方法研究氢在裂纹尖端行为的力学响应.研究结果表明,裂纹尖端吸附的氢降低了原子间的键合力,导致局部应力集中所需的临界外加载荷减小;使得材料在较低的断裂强度条件下发生破坏,并在很大程度上促进了裂纹的扩展.模拟观察到在外加载荷下吸附氢在裂纹尖端的渗透过程,氢原子会聚集在高应力区域,造成材料塑性降低.另外,渗透进材料的氢原子数目会随着计算时间的增加达到一个最大临界值.当施加应变增大,裂纹尖端渗透氢原子数最大临界值和达到临界值的时间会增加.
