Abstract: A power module includes a first metal layer, a first base, a metal shield layer, and a second base. The first base includes a first side edge and a second side edge that are opposite, and the second base includes a third side edge and a fourth side edge that are opposite. A distance between the first side edge and the second side edge is equal to a distance between the third side edge and the fourth side edge. Projection of the first side edge on the second base is located on a same straight line as the third side edge, and projection of the second side edge on the second base is located on a same straight line as the fourth side edge. The first metal layer and the first base are provided with openings, and a first pin is connected to the metal shield layer via the openings.

The drive circuit of the power device includes: a drive signal generation circuit, configured to generate a drive signal; a resistor and a capacitor that are connected in series, coupled to the drive signal generation circuit and the power device, and configured to control turn-on and turn-off of the power device based on the drive signal; and a voltage clamp circuit, coupled to the power device, and configured to control a gate voltage of the power device to be not greater than a gate withstand voltage.

Abstract: Described herein are nanoparticles comprising a mixture of a steroid, a phospholipid composition, an ?-tocopheryl compound, and a therapeutic agent wherein the ?-tocopheryl compound is presented on the surface of the nanoparticle. In some embodiments, the nanoparticles are useful for delivering a peptide or a protein. In some embodiments, the nanoparticles are formulated for ocular administration. In other embodiments, the nanoparticles are formulated to cross the blood brain barrier for the delivery of the therapeutic agents to the brain.

Abstract: Pharmaceutical composition comprising a pharmaceutically acceptable oil phase, a surfactant, and a therapeutic agent are provided herein, wherein the composition is in the form of a pro-nanoparticle or a self-assembling nanoparticle. Additionally, these pharmaceutical compositions have high loading of the therapeutic agent. Also provided herein are methods of preparing the pharmaceutical compositions and methods using the compositions in the treatment of a patient.

Abstract: A wind power generator system installed on the ground or ocean floating surface includes wind propeller, tower, Z-shaped mechanical transmission module, multiple stage gear box, fixed ratio gear box, transmission device, and alternating current generators coupled by a clutch between any two generators. The wind propeller is installed on top of the tower and is connected to the top side of Z-shaped mechanical transmission module which transfers the revolution mechanical power from top of the tower to the bottom of the tower.

Abstract: Nanocapsule and nanoemulsion particle compositions having improved physical and pharmacological properties are provided. The nanocapsule or nanoemulsion particle composition can comprise a pharmaceutically acceptable liquid oil phase, a surfactant, and optionally a co-surfactant. The liquid oil phase can comprise a monoglyceride, a diglyceride, a triglyceride, a propylene glycol ester, or a propylene glycol diester. In certain embodiments, the nanocapsule or nanoemulsion particle composition can be lyophilized and subsequently re-hydrated without increasing the mean particle size and/or adversely affecting the potency or efficacy of a therapeutic agent (e.g., paclitaxel) present in the nanocapsules or nanoemulsion particles.
