    Abstract: This disclosure describes a sensor for detecting vibrations, particularly low-frequency vibrations. The sensor is of a cascaded gapped cantilever construction and may include a single sensing beam extending from a base to a proof mass across the plurality of gaps, a mechanical beam opposite the piezoelectric beam. The sensor may be included in a system including a housing, a support, and electronic components for converting and measuring signal. The sensor may be mounted to an item of furniture, such as a bed or a sofa, and measure physiological data including ballistocardiogram and respiratory data of a subject positioned on the furniture.

    Abstract: Low-temperature organometallic nucleation and crystallization-based synthesis methods for the fabrication of semiconductor and metal colloidal nanocrystals with narrow size distributions and tunable, size- and shape-dependent electronic and optical properties. Methods include (1) forming a reaction mixture in a reaction vessel under an inert atmosphere that includes at least one solvent, a cationic precursor, an anionic precursor, and at least a first surface stabilizing ligand while stirring at a temperature in a range from about 50° C. to about 130° C. and (2) growing nanocrystals in the reaction mixture for a period of time while maintaining the temperature, the stirring, and the inert-gas atmosphere.

    Abstract: A multi-core processor provides circuitry for jointly scaling the number of operating cores and the amount of resources per core in order to maximize processing performance in a power-constrained environment. Such scaling is advantageously provided without the need for scaling voltage and frequency. Selection of the number of operating cores and the amount of resources per core is made by examining the degree of instruction and thread level parallelism available for a given application. Accordingly, performance counters (and other characteristics) implemented in by a processor may be sampled on-line (in real time) and/or performance counters for a given application may be profiled and characterized off-line. As a result, improved processing performance may be achieved despite decreases in core operating voltages and increases in technology process variability over time.

    Abstract: A method of growing carbon nanostructures on a conductive substrate without the need for a vacuum or low-pressure environment provides high electrical field strengths to generate the necessary carbon ions from a feedstock gas and to promote alignment and separation of the resulting structures. In one embodiment, substantially uniform “vertical” nanostructures may be formed around the periphery of an extended wire for use in corona discharge applications or the like. Growth on a planar substrate may provide use with a variety of apparatus requiring a high specific surface conductor such as capacitors, batteries, and solar cells.

    Abstract: Systems and methods for signal analysis are described. The method can include digitizing a signal modulated by a pseudo noise (PN) sequence, dividing the digitized signal into a plurality of sample blocks, and estimating a PN phase embedded in a sample block of the plurality of sample blocks using an iterative message passing algorithm (iMPA) executed on a redundant graphical model.
