摘要: Inverters that interface dc and ac power sources and loads are provided. An example application is solar power systems, in which a dc source of power is an array of solar panels; the inverter converts the dc power supplied by these panels to ac power that is fed into the utility grid. Another example is battery energy storage; the inverter changes the dc power of the batteries into ac power that is fed into the grid, and also can convert (rectify) ac power from the grid for charging the batteries. In one embodiment, for example, an inverter comprises slow switches that generate a three-level ac voltage, followed by a plurality of fast-switching half-bridges that introduce high-frequency pulse-width modulation into a plurality of ac output voltages.

摘要: Some embodiments of the invention include a thermal ground plane with a variable thickness vapor core. For example, a thermal ground plan may include a first casing and a second casing where the second casing and the first casing configured to enclose a working fluid. The thermal ground plane may also include an evaporator region disposed at least partially on at least one of the first casing and the second casing; a condenser region disposed at least partially on at least one of the first casing and the second casing; and a wicking layer disposed between the first casing and the second casing a vapor core defined at least partially by a gap between the first casing and the second casing. The thickness of the gap can vary across the first casing and the second casing.

摘要: Chronological age is an important predictor of morbidity and mortality, however it is unable to account for heterogeneity in the decline of physiological function and health with advancing age. Several attempts have been made to instead define a “biological age” using multiple physiological parameters in order to account for variation in the trajectory of human aging; however, these methods require technical expertise and are likely too time-intensive and costly to be implemented into clinical practice. Accordingly, a metabolomic signature of biological aging was developed that can predict changes in physiological function with the convenience of a blood sample. A weighted model of biological age was generated based on multiple clinical and physiological measures in a large group of healthy adults and was then applied to a cohort of healthy older adults who were tracked longitudinally over a 5-10 year timeframe. Plasma metabolomic signatures were identified that were associated with biological age, including some that could predict whether individuals would age at a faster or slower rate. These results not only have clinical implications by providing a simple blood-based assay of biological aging, but also provide insight into the molecular mechanisms underlying human healthspan.

摘要: A serpentine integrated grating spectrometer includes a serpentine delay line and a plurality of grating couplers. The serpentine delay line includes a plurality of parallel waveguide segments that are coplanar in a delay-line plane. The serpentine delay line serially connects each of the plurality of grating couplers. Each of the plurality of grating couplers (i) is located at a respective one of the plurality of parallel waveguide segments, and (ii) direct light propagating in the serpentine delay line out of the delay-line plane. The plurality of waveguide segments is M in number and impart a total group delay time ry on light propagating therethrough. Each of the plurality of grating couplers impart a grating coupler delay tx on light propagating therethrough that exceeds (ty/M), the time delay for a single segment of the M parallel segments.
