Abstract

We report a universal approach based on the surface plasmon resonances (SPRs) attained in filamentation in water doped with gold nanoparticles for enhancing the nonlinear refractive index. The filament-induced supercontinuum spectrum in water overlaps with SPRs of gold nanospheres, which further leads to a modification on the Kerr nonlinear refractive index. In our experiment, the measured nonlinear refractive index (n2) in water doped with gold nanoparticles increases by six times, as compared with that in pure water. Such enhancement may be useful for filament-induced nonlinear applications with modest incident intensity.

Abstract

This book is based on the authors' research and microgrid projects since 2009, and is the most up-to-date resource on the development of microgrid technologies. In addition to basic facility and network design concepts, it covers related subjects including power supply programming and energy optimization, which means it can serve as a single volume reference to the complete microgrid system implementation. Provides a systematic introduction to the basic concepts, key technologies, and practical design methods of microgridsCovers the theoretical design and implementation of microgrid facilities, including practical operational issues, monitoring and control. The balance of theoretical and applied content will be of real value to engineers who are specifying and design systems in regions with limited experience of microgrid systemsIncludes real-life examples and projects to help implement the content effectively

Abstract

Axonal regeneration is minimal after CNS injuries in adult mammals and medical treatments to recover neurological deficits caused by axon disconnection are extremely limited. The failure of axonal elongation is principally attributed to the nonpermissive environment and reduced intrinsic growth capacity. In this report, we studied the role of glycogen synthase kinase-3 (GSK-3) inactivation on neurite and axon growth from adult neurons via combined in vitro and in vivo approaches. We found that the major CNS inhibiting substrates including chondroitin sulfate proteoglycans could inactivate protein kinase B (Akt) and activate GSK-3beta signals in neurons. GSK-3 inactivation with pharmacologic inhibitors enhances neurite outgrowth of dorsal root ganglion neurons derived from adult mice or cerebellar granule neurons from postnatal rodents cultured on CNS inhibitors. Application of GSK-3 inhibitors stimulates axon formation and elongation of mature neurons whether in presence or absence of inhibitory substrates. Systemic application of the GSK-3 inhibitor lithium to spinal cord-lesioned rats suppresses the activity of this kinase around lesion. Treatments with GSK-3 inhibitors including a clinical dose of lithium to rats with thoracic spinal cord transection or contusion injuries induce significant descending corticospinal and serotonergic axon sprouting in caudal spinal cord and promote locomotor functional recovery. Our studies suggest that GSK-3 signal is an important therapeutic target for promoting functional recovery of adult CNS injuries and that administration of GSK-3 inhibitors may facilitate the development of an effective treatment to white matter injuries including spinal cord trauma given the wide use of lithium in humans.
