Apolipoprotein (apo) E, a polymorphic protein with three isoforms (apoE2, apoE3, and apoE4), is essential for lipid homeostasis. Carriers of apoE4 are at higher risk for developing Alzheimer's disease. We have investigated adult neurogenesis in mice with knockout (KO) for apoE or with knockin (KI) alleles for human apoE3 or apoE4, and we report that(More)
Insect viruses have evolved strategies to control the host RNAi antiviral defense mechanism. In nature, Drosophila melanogaster C virus (DCV) infection causes low mortality and persistent infection, whereas the closely related cricket paralysis virus (CrPV) causes a lethal infection. We show that these viruses use different strategies to modulate the host(More)
The combination of high accuracy, sensitivity and speed of single and multiple-stage mass spectrometric analyses enables the collection of comprehensive sets of data containing detailed information about complex biological samples. To achieve these properties, we combined two high-performance matrix-assisted laser desorption ionization mass analyzers in one(More)
Checkpointing is one of the commonly used techniques to provide fault-tolerance in distributed systems so that the system can operate even if one or more components have failed. However, mobile computing systems are constrained by low bandwidth, mobility, lack of stable storage, frequent disconnections and limited battery life. Hence, checkpointing(More)
An end-point temperature prediction model based on RBF neural network is developed to reduce the measuring cost and improve the measuring accuracy in a vacuum induction furnace. It can give reliable predictions of tapping time and temperature of molten steel in the first-round prediction. And the prediction accuracy can be improved by the error correction(More)
