The quality of machined marine propellers plays a critical role in underwater propulsion performance. Precision casting is the predominant manufacturing technique; however, deformation of wax models and rough blanks during manufacturing frequently cause deviations in the dimensions of final products...

In order to achieve the optimal stator–rotor combinations of conventional flux-switching permanent magnet (FSPM) machines, this paper proposes and analyzes a general principle with prime phase numbers. Based on the coil complementarity concept, the proposed methodology specifically addresses the pha...

Primary human mammary epithelial cells have a limited life span which makes it difficult to study them in vitro for most purposes. To overcome this problem, we have developed a cell line that was immortalized using defined genetic elements, and we have characterized this immortalized non-tumorigenic...

Impressively high-photoresponse performance was observed from copper sulfide/silicon heterojunction photodetectors, which were fabricated by chemical vapor depositing (CVD) p-type copper sulfide (CuxS) thin films onto n-type Si substrates. This CVD technique, being facile, cost-effective, low-temper...

Objectives Azvudine and Paxlovid are the primary antiviral agents for the management of COVID-19. However, there is currently insufficient evidence regarding the effectiveness and safety of these drugs in treating COVID-19 patients with pre-existing hypertension. The objective of this study was to a...
