A Novel Lipid-Polymeric Hybrid Nanoparticle Based Nicotine Vaccine to Treat Nicotine Addiction
Tobacco addiction has consistently been the top preventable cause of many serious diseases, and results in huge mortality, morbidity, and economic loss in recent decades. Despite the strong willingness to quit smoking, most of the smokers cannot achieve long term abstinence without medical interventions. However, current FDA approved pharmacological...

Controlled Release of Antigen In Dendritic Cells Using pH-Sensitive Liposome-Polymeric Hybrid Nanoparticles
A nano delivery system that can stay stable during circulation in vivo, as well as enables rapid release of the encapsulated antigen in dendritic cells would be of great value in vaccine development. Here, we present the development of a nano hybrid particle consisting of a pH sensitive lipid shell and a poly (lactic-co-glycolic) acid (PLGA) core. This...

Adaptive On-Time Control for PFC Light Load Efficiency Improvement
Light load efficiency of a power factor correction circuit is improved by adaptive on-time control and providing for selection between a continuous conduction mode and a discontinuous conduction mode wherein the discontinuous conduction mode increases time between switching pulses controlling connection of a cyclically varying voltage to a filter/inductor...

Novel Interleaving Strategy for Multi-Channel PFC
Interleaving multi-phase PFC to reduce the input ripple current is a very popular technology for the AC-DC switching mode power supply. With smaller input ripple current, the EMI filter size can be reduced so that higher power density can be achieved. However, by applying this interleaving technology for today’s AC-DC power supply, the EMI filter...
