Males generally exhibit reduced immune responses and greater susceptibility to disease than females. The suppressive effect of testosterone on immune function is hypothesized to be one reason why males have lower immune responses than females. Presumably, this effect of testosterone should be more pronounced among polygynous than monogamous species because circulating testosterone is higher amo...

Abstract Regarding porosity formation and gas content, choosing the appropriate shielding for laser welding is essential achieving high-quality joints. Keyhole-induced tendency nitrogen content in SS 304 stainless steel welds were investigated based on gases during fiber welding. Beads-on-plate autogenous made at 5 kW continuous wave (CW) N 2 Ar mixtures. Optical metallography, micro-focused X-...

A tracking algorithm is proposed to measure the velocity of red blood cells traveling through microvessels of tumors growing in skin flaps implanted on mice. The tracking is based on a keyhole model that describes the probable movement of a segmented cell between contiguous frames in a video sequence. When a history of movements exists, past, present and a predicted landing position define two ...

With an advantage of “single-sided welding and double-sided forming,” plasma arc (PAW) has a great application potential in modern industrial production. The quality can be guaranteed by sensing controlling the keyhole. However, it is difficult to make on-line observation on back base metal, realize dynamic registration visual sensor torch. In this study, investigated relationship between condi...
