One of the endovascular devices, a drug-eluting stent (DES), proved to be a safe and effective therapeutic option for cardiologists, substantially reducing in-stent restenosis (ISR) rates. DES consists of thin (< 200 µm) or ultra-thin (< 70 µm) struts made of Cobalt-Chromium (CoCr) or other alloys. The DES with ultra-thin struts exhibits higher longitudinal flexibility and improved trackability. It also reduces vascular injury and promotes more rapid endothelization, substantially decreasing the risk of ISR. This study evaluates comprehensive mechanical performances of two different structural designs of newly developed ultra-thin CoCr stents (i.e., strut width of 75 µm or 65 µm). These two stent designs are engineered with distinct bridge size and distribution patterns, prioritizing enhanced flexibility irrespective of the strut thickness. Computational modeling results show anticipated stress distribution with maximum local stresses, which are compared with experimental outcomes conducted in this study. ASTM <span>guideline</span><svg><path></path></svg> based in vitro experimental studies have been conducted to assess the stents’ longitudinal flexibility, radial strength, recoil and shortening, as well as crushability through this study. Three-point bending experiments have demonstrated that the stent design 1 requires less bending force compared to the design 2, showing better longitudinal flexibility of the stent design 1 in the collapsed state for the new ultra-thin DES devices. The design 1 also showed superior radial strength and recoiling phenomena, as well as smaller shortening. In short, the stent design 1 shows better mechanical performance needed for the coronary artery DES.</p></div>","PeriodicalId":72384,"journal":{"name":"Biomedical engineering advances","volume":"6 ","pages":"Article 100097"},"PeriodicalIF":0.0,"publicationDate":"2023-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49732768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chassis by wire technology is a key technology involved in intelligent driving of new energy vehicles, and is also an effective support for promoting the continuous updating and development of intelligent driving. It is a hot issue in the research, development and manufacturing of new energy vehicles at this stage. Chassis by wire technology is a key technology for the update and development of intelligent driving of new energy vehicles, and is an inevitable choice for intelligent driving of future vehicles. The application of chassis by wire technology has changed the complex mechanical connection equipment, hydraulic, pneumatic and other components in the past, greatly promoting the improvement of energy efficiency and the sustainable endurance of new energy vehicles. At present, the consensus in the new energy vehicle industry is \"wireless control without autonomous driving\", which also well illustrates the important position of chassis by wire technology in the intelligent driving field of new energy vehicles. Based on the author's actual research, the structure of intelligent driving by wire system for new energy vehicles and the basic principle of chassis by wire technology is discussed, and the full vector control chassis by wire technology is analyzed.","PeriodicalId":72384,"journal":{"name":"Biomedical engineering advances","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82822865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the past, enterprise applications generally had available resources to deal with security algorithms at any time, but nowadays, enterprise-level IoT applications are suffering from increasing threats, and their attack targets are the expanding network of resource-constrained IoT devices. When enterprises are eager to meet the rapidly emerging opportunities of the Internet of Things, the deployed IoT devices often fail to support basic security measures in function, so it is difficult to protect the stored data, and it is impossible to guarantee the exchange of data and commands on vulnerable networks. The thesis is about the comparison of encryption algorithms for wearable devices. Because the most popular wearable devices in the market are smartwatches, choosing the smartwatches as sample to analysis. Moreover, based on the current cryptographic protocol standards that are being used in IoT, choosing AES, PRESENT, RSA and ECC algorithms as the comparison in the encryption algorithms. Also, the hybrid algorithm called HAN show impressive potential and security in encryption.","PeriodicalId":72384,"journal":{"name":"Biomedical engineering advances","volume":"68 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76132271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
