Abstract: A system for assaying forces applied by cells includes an optically transparent substrate comprising a soft material having a Young's modulus within the range of about 3 kPa to about 100 kPa. An array of molecular patterns is disposed on a surface of the optically transparent substrate, the molecular patterns include fluorophore-conjugated patterns adherent to cells. The system includes at least one light source configured to excite the fluorophore-conjugated patterns and an imaging device configured to capture fluorescent light emitted from the fluorophore-conjugated patterns. Dimensional changes in the size of the patterns are used to determine contractile forces imparted by cells located on the patterns.

Abstract: A Modular Multilevel Converter (MMC) circuit for converting DC power to AC and vice versa. At each respective connection to the AC power-source/load, the MMC circuit uses one Pulse Width Modulation Insulated Gate Bipolar Transistor (PWM IGBT) to control the switching between upper and lower arms of sub-modules. The circuit eliminates the inter-phase inductors often used in MMCs, and replaces the inductors by two complementary-gated PWM IGBTs, thereby eliminating circulating current. Moreover, the multilevel converter topology disclosed herein requires less number of components including PWM IGBTs and capacitors. In fact, at least two submodules per-phase are eliminated: one submodule in the upper arm and one submodule in the lower arm. In other words, the MMC topology not only mitigates the circulating current but also eliminates at least one submodule in the upper arm and at least one submodule in the lower arm per-phase.

Abstract: A method for fabricating a composite film structure, the method includes determining a desired morphology for a metallic layer of the composite film structure, selecting a first metal substrate based on the determining, transferring a graphene layer onto the first metal substrate, depositing the metallic layer on the graphene layer to achieve the desired morphology, and removing the first metal substrate from the graphene and the deposited metallic layer to form the composite film structure. A surface energy difference between the first metal substrate and the deposited metallic layer results in the desired morphology of the metallic layer.

Abstract: A III-nitride optoelectronic device includes at least one n-type layer, an active region grown on or above the n-type layer, at least one p-type layer grown on or above the active region, and a tunnel junction grown on or above the p-type layer. A conductive oxide may be wafer bonded on or above the tunnel junction, wherein the conductive oxide comprises a transparent conductor and may contain light extraction features on its non-bonded face. The tunnel junction also enables monolithic incorporation of electrically-injected and optically-pumped III-nitride layers, wherein the optically-pumped III-nitride layers comprise high-indium-content III-nitride layers formed as quantum wells (QWs) that are grown on or above the tunnel junction. The optically-pumped high-indium-content III-nitride layers emit light at a longer wavelength than the electrically-injected III-nitride layers.

Abstract: Systems and methods of determining physical conditions of a battery, such as state of charge (SOC), state of health (SOH), quality of construction, defect, or failure state include driving two or more acoustic signals of two or more amplitudes, each acoustic signal having two or more frequencies, into the battery and detecting vibrations generated in the battery based on the two or more acoustic signals. Nonlinear response characteristics of the battery for the two or more acoustic signals are determined from the detected vibrations. The physical conditions of the battery are determined based at least in part on the nonlinear response characteristics, using nonlinear acoustic resonance spectroscopy (NARS) or nonlinear resonant ultrasound spectroscopy (NRUS).

Abstract: Methods for predicting patient deterioration or clinical events by detecting patterns in heterogeneous temporal clinical data streams that are predictive of certain clinical end points and matching the patient state with those patterns are described. The detected patterns, referred to as SuperAlarm triggers, are a predictive combination of frequently co-occurring monitor alarms, conditions and laboratory test results that can predict patient deterioration for imminent life-threatening events. SuperAlarm triggers may also exhibit patterns in the sequence of SuperAlarms that are triggered over the monitoring time of a patient. Sequential patterns of SuperAlarm triggers may also indicate a temporal process of change in patient status. SuperAlarm based alerts will also greatly reduce the number of false alarms and alarm fatigue compared to conventional alarms.

Abstract: A heterodyne optical spectroscopy system comprises a light source that acts as a local oscillator (LO); a beam splitting component that generates a reference beam from the LO; a signal component that generates a sample signal from a sample; a beam blocker that can turn off the sample signal to generate blank shots; a composite signal detection subsystem that detects a heterodyned signal that is a mix of the sample signal and a portion of the LO; a composite reference detection subsystem synchronized to the signal detection subsystem to detect a portion of the reference beam; and a processor that processes digital signals from the signal detection subsystem and the reference detection subsystem. A very versatile reference scheme is developed to treat different heterodyne spectroscopies in a unified way, which achieves optimal noise suppression.
