Abstract:
A computer architecture allows for simplified recovery after mis-speculation during speculative execution by controlling speculation to occur within idempotent regions that may be recovered by re-execution of the region without the need for restoring complex state information from checkpoints. A compiler for increasing the size of idempotent regions is also disclosed.
Abstract:
This disclosure describes techniques for constructing power spectral density (PSD) maps representative of the distribution of radio frequency (RF) power as a function of both frequency and space (geographic location). For example, the disclosure describes techniques for construction PSD maps using non-parametric basis pursuit form of signal expansion.
Abstract:
Embodiments of the present invention address deficiencies of the art in respect to positioning for geophysical sensing and provide a method, system and apparatus for rotary laser positioning in geophysical sensing. In an embodiment of the invention, a geophysical sensing data processing system can be provided to include multiple laser energy sources disposed about a target scene, and a mobile sensor unit. The mobile sensor unit can include at least one laser energy source sensor coupled to a laser positioning system, and one or multiple geophysical sensor communicatively linked to the laser positioning system. In one aspect of the invention, the laser positioning system can be a Rotary Laser Positioning System (RLPS). Complementary positioning sensors further can be provided.
Abstract:
A lithium hydrogen titanate Li—H—Ti—O material includes Li, H, Ti, and O elements, wherein a mass percentage of Li is in a range from about 3% to about 12%, a mass percentage of H is in a range from about 0.1% to about 8%, a mass percentage of Ti is in a range from about 46% to about 56%, and a mass percentage of O is in a range from about 28% to about 50%. A lithium ion battery and a method for making the lithium hydrogen titanate Li—H—Ti—O material are also disclosed.
Abstract:
Disclosed are polymerizable mixtures comprising a functionalized ionic gemini surfactant and a thiol-ene crosslinking agent. The polymerizable mixtures that further comprise a polar solvent may be used to form the surfactant into a triply periodic multiply continuous lyotropic phase in the presence of the crosslinking agent. Upon crosslinking, the lyotropic phase morphology is substantially retained.
Abstract:
A method of manufacturing an organic semiconductor thin film includes coating an organic semiconductor solution on a substrate, and shearing the organic semiconductor solution in a direction that results in a shearing stress being applied to the organic semiconductor solution to form the organic semiconductor thin film, wherein a speed of the shearing is controlled such that an intermolecular distance of the organic semiconductor solution is adjusted.
Abstract:
A photolithography method of patterning photoresist involves disposing a two-dimensional array of focusing particles of spherical or other shape on the photoresist and illuminating the particles on the photoresist to generate deep, sub-wavelength patterns on the photoresist. When developed, a positive photoresist layer generates a two-dimensional array of micro- or nano-holes on the developed photoresist. When developed, a negative photoresist layer generates a two-dimensional array of micro- or nano-pillars on the developed photoresist.
