Geometrical aberration measurement by experimental ray-tracing based on fiber point diffraction interferometry Open
The geometrical aberration of an optical system is usually measured through wavefront aberration. We propose a very direct experimental ray-tracing measurement method in this paper. Two fiber point-light-sources are used to simulate an arb…

Haemolysin <span>Sph2</span> of <span> <i>Leptospira interrogans</i> </span> induces cell apoptosis via intracellular reactive oxygen species elevation and mitochondrial membrane injury Open
Leptospira interrogans causes widespread leptospirosis in humans and animals, with major symptoms of jaundice and haemorrhage. Sph2, a member of the sphingomyelinase haemolysins, is an important virulence factor for leptospire. In this stu…

Identification and Characterization of c-di-GMP Metabolic Enzymes of Leptospira interrogans and c-di-GMP Fluctuations After Thermal Shift and Infection Open
Leptospirosis is a widespread zoonotic disease caused by pathogenic Leptospira species. The most common species, Leptospira interrogans, can transfer from contaminated soil or water to the human body. It is able to survive th…

Experiments and kinematics analysis of a hand rehabilitation exoskeleton with circuitous joints Open
Aiming at the hand rehabilitation of stroke patients, a wearable hand exoskeleton with circuitous joint is proposed. The circuitous joint adopts the symmetric pinion and rack mechanism (SPRM) with the parallel mechanism. The exoskeleton fi…
