TL;DR: In this paper, the authors showed that C dots can be electrostatically coated with cationic polymers, changing their surface charge and enabling them to escape from endosomes and enter the cytoplasm and nucleus.

TL;DR: In this paper, the primal-dual interior-point filter is used to solve the problem of global convergence to first-order critical points in nonlinear nonlinear programs, without the use of merit functions and penalty parameters.
Abstract: In this paper, the filter technique of Fletcher and Leyffer (1997) is used to globalize the primal-dual interior-point algorithm for nonlinear programming, avoiding the use of merit functions and the updating of penalty parameters.The new algorithm decomposes the primal-dual step obtained from the perturbed first-order necessary conditions into a normal and a tangential step, whose sizes are controlled by a trust-region type parameter. Each entry in the filter is a pair of coordinates: one resulting from feasibility and centrality, and associated with the normal step; the other resulting from optimality (complementarity and duality), and related with the tangential step.Global convergence to first-order critical points is proved for the new primal-dual interior-point filter algorithm.

TL;DR: Results indicate that A(2A) receptors in the striatum are not enriched in synapses in agreement with the preponderant role of A(3)H]SCH 58261 receptors in signal processing in striatopallidal neurons, in contrast, hippocampal A(1) receptors are enriched in Synaptosomal in accordance with their role in controlling neurotransmitter release.

09 May 1999TL;DR: In this paper, a new approach, based on the average motor supply current Park's vector monitoring, was introduced for diagnosing voltage source inverter faults in variable speed AC drives.
Abstract: This paper introduces a new approach, based on the average motor supply current Park's vector monitoring, for diagnosing voltage source inverter faults in variable speed AC drives. Both simulation and laboratory tests results demonstrate the effectiveness of the proposed on-line diagnostic technique.
