The first thickness of the first barrier layer located directly under the P-type gallium nitride layer is greater than the second thickness of the first barrier layer located on two sides of the P-type gallium nitride layer.

Abstract: The present invention provides a method for preparing a reconstituted apolipoprotein B lipoparticle and the method comprises steps of (a) dissolving an apolipoprotein B and a lipid in a first buffer containing 2 M to 8 M urea and 1 wt % to 15 wt % amphiphilic compounds to form a mixture; and (b) dialyzing the mixture against a second buffer containing 0 M to 2M urea and 0 wt % to 0.5 wt % amphiphilic compounds for 1 to several times for lowering concentrations of the urea and the amphiphilic compounds in the mixture. The present invention further provides an apolipoprotein B lipoparticle and a use for the production of an apolipoprotein B lipoparticle used for delivering a hydrophobic substance.

Abstract: Connection establishing management methods for traversing network address translation (NAT) routers and firewalls between network terminal devices to establish a connection channel therebetween for use in a network system including at least first, second and third network terminal devices and a traversal server are disclosed. First, when traversal server receives a call request of first and second network terminal devices, network topology levels of first and second network terminal devices are detected to detect whether first and second network terminal devices are located behind NAT router and/or firewall. Then, one of first and second network terminal devices or third network terminal device is selected according to the detection result such that selected network terminal device acted as proxy server for the traversal server to establish a connection channel corresponding to call request between first and second network terminal devices.

Abstract: Data management methods for use in a network system including at least first, second and third network terminal devices and traversal server are disclosed. First and second network terminal devices can traverse at least one NAT router and/or firewall to establish a connection channel between each other for data access through traversal server. The method includes the steps of: receiving first packet with first protocol format from first network terminal device; determining whether to perform protocol conversion operation; if so, obtaining a list of available network terminal devices, assigning first network terminal device from obtained list, converting first packet with first protocol format into second packet with second protocol format that is decodable by second network terminal device, and sending second packet to second network terminal device such that second network terminal device can obtain content of first packet by decoding second packet upon reception of second packet.

Abstract: A drug administration port of infusion set and catheter needle set, including: a drug administration socket having a drug through hole, a free end of the drug administration socket being formed with a seat defining an opening communicating with the drug through hole; a plastic plug for blocking the opening of the seat; and a connecting member connected with the free end of the drug administration socket. The connecting member has a tapered hole axially positioned on the upper face of the plastic plug. A small diameter end of the tapered hole faces the plastic plug. A threaded section is formed on an opposing end of the connecting member. An upper face of the plastic plug is cut with a split axially corresponding to the position of the tapered hole. The split serves to communicate with the drug through hole.
