Abstract: Natural occurring inhibitors of cyclin-dependent protein kinase 5 (Cdk5), isolated from the root of Rhodiola rosea are structurally different from the known Cdk inhibitors. They show selectivity among different Cdks and efficacy to inhibit Cdk via a mixed-type of inhibition, which should lead to less toxicity and side-effects. They are useful in preventing and treating diseases and disorders associated with aberrant Cdk5 activities, such as acute and/or chronic pain, neuropathic pain, diabetes mellitus, cancer, neurodegenerative diseases and neuropathological disorders.

Abstract: A charge pump (CP) that operates at low input voltage with high power conversion efficiency is disclosed. A first embodiment provides a negative CP used for controlling load switches of a voltage doubler. Using a negative CP extends the operating region below ground to relieve the power delivery limitation of the CP. A second embodiment provides a low power adaptive dead-time circuit, which has several dead-time signals having different lengths of dead-times and selects one according to the input voltage level. A low input voltage detector in the adaptive dead-time circuit is used to determine which dead-time should be used. A third embodiment provides a switching body bias used for the low input voltage CP. The switching body bias uses both forward and reverse body bias applied to the CP to minimize reverse current and maximize power transfer. The first, second, and third embodiments can be used together or independently.

Abstract: A thermal interface material provides thermal conduction or thermal dissipation across an interface, using a three-dimensional interconnected porous graphene (3D-IPG) foam structure. The 3D-IPG foam structure is constructed of three-dimensional interconnected graphene sheets formed as a plurality of monolayers, and having an flexible interconnection architecture. The flexible interconnection architectures allow the 3D-IPG to maintain a high interfacial thermal conductance by the 3D-IPG filling a gap between a heat source and a heat sink across the interface, and by capping small features up to nanoscale roughened surfaces.

Abstract: Systems, methods and apparatus facilitating joint channel and routing assignment are provided. In some embodiments, a system includes nodes in a network configured to perform distributed joint channel and routing assignment of traffic through exchange of information with one another. The assignments are iteratively updated based on whether the update will result in an increase in a value of a function associated with throughput for traffic in the network. In some embodiments, the assignments are determined based on random decisions that are adopted if the function is improved utilizing the routing and channel information in the assignment. In some embodiments, the assignments are determined based on traffic prioritization in which destination nodes having a high level of traffic are assigned routes and channels having characteristics amenable to reduction of interference in the network.

Abstract: Described herein are systems and methods that employ a widgetless and buttonless multi-touch interface for constrained manipulations of 3D objects. The widget-less multi-touch user interface can map different multi-touch gestures to different 3D object manipulation tasks, allowing a user to manipulate 3D objects without operating widgets or performing mode switchings or tool selections. User interaction is greatly simplified by using single touch actions that simultaneously specify the transformation constraint, the transformation type, and the magnitude of transformation and apply the transformation to the focus object. Additionally, the axis-based constrained manipulations support active snapping and axis transfer. Active snapping allows the user to draw a free touch path connecting two 3D objects to be snapped together, avoiding tedious operations required with standard transformation manipulations.
