Abstract: The present disclosure belongs to the technical field of pathogen detection, in particular to loop-mediated isothermal amplification (LAMP) primer sets for detecting porcine susceptibility-related pathogenic bacteria, and a kit, a LAMP chip and use based on the same. The LAMP primer sets for detecting porcine susceptibility-related pathogenic bacteria include an Actinobacillus pleuropneumoniae primer set, a Haemophilus parasuis primer set, a Salmonella choleraesuis primer set, a Bordetella bronchiseptica primer set, a Pasteurella multocida primer set, a Streptococcus suis primer set, and an Erysipelothrix rhusiopathiae primer set.

Abstract: A super-junction device and a method of fabricating such a device are disclosed, in which a pillar of a second conductivity type situated at an interface between a transition region and a core region is narrowed in width across at least an upper thickness thereof, thereby reducing peak electric field strength in the transition region, increasing voltage endurance of the transition region and preventing the occurrence of avalanche breakdown first in the transition region. Additionally, a dopant ion concentration profile increasing in the direction from the transition region to the core region is created across upper portions of some pillars of the second conductivity type in the core region, which increases the presence of the dopant of the second conductivity type around the surface of the core region and thus stops a vertical electric field before it can reach wells of the second conductivity type.

Abstract: An electrical connector assembly includes a first connector and a second connector inserted to a front of the first connector. The second connector has a casing. A latch portion is protrudingly provided above the casing. The first connector includes a shell. A locking arm is pivoted to the shell by a pivoting portion, and is provided with a buckling portion for buckling the latch portion. The locking arm includes at least one first position limiting portion and a second position limiting portion in front of the buckling portion. In a separation process of the first and second connectors, the locking arm is actuated, the buckling portion is detached from the latch portion and moves backward, and the latch portion firstly stops the first position limiting portion. After the latch portion is detached from the first position limiting portion, the latch portion stops the second position limiting portion from moving backward.
