Lip Treatments In order to explore the mechanism of bionic propulsion and bionic robots, to make up for the limitations of traditional propulsion with a uniform incoming flow, numerical methods are used to couple fluid dynamics and flapping foil motions, and a flapping-fluid coupling self-propulsion calculation model is established in this paper.K
There is increased attention paid to metallic nanoparticles due to their intensive use in various branches of agriculture and biotechnology, such as pest management, nanosensors, gene delivery, seed treatment, etc.There has been growing interest in applying environmentally friendly strategies for synthesizing nanoparticles without using substances
In the literature of distributed database system (DDBS), several methods sought to meet the satisfactory reduction on transmission cost (TC) and were seen substantially effective.Data Fragmentation, site clustering, and data distribution have been considered the major leading TC-mitigating influencers.Sites clustering, on one hand, aims at grouping
Abstract Background Pulmonary artery sarcomas (PASs) are Cotton Jackets rare, and complete tumor resection is often difficult at the time of detection.We encountered a case of PAS that was thought to be resectable; however, the patient had severe symptomatic valvular disease.We faced a difficult decision regarding the surgical strategy.Case present
Abstract We consider two BF formulations of the theory of gravity with a negative cosmological constant, of Plebanski and of MacDowell-Mansouri.Both give the standard Einstein equations in the bulk but differ in expressions of edge charges.We compute the asymptotic charges explicitly in both theories for AdS-Schwarzschild, AdS-Kerr, and AdS-Taub-NU
