Abstract: Disclosed is a technology for assaying individual cells, in which the identity of each individual cell in an ordered array is determined from coordinates assigned to it, and can be readout at high throughput with microscope. The method is able to test responses of millions of identical cells in multiple chemical and physical processes with superior statistics power to facilitate deep data mining.

Abstract: Disclosed is a method for detecting a metal ion in an aqueous solution, the method comprising immersing a hydrogel in the aqueous solution, wherein the hydrogel comprises a prefluorescent imaging moiety that is activated upon binding the metal ion. The method enables detection of lead ions in water.

Abstract: Disclosed is a composite material, comprising a polymer, a plurality of metal nanoparticles, and a surface-modifying agent (e.g., nanocellulose). Also disclosed is a method for shielding a subject from electromagnetic radiation, comprising placing one or more composite materials between the subject and a source of electromagnetic radiation, thereby reducing a dose of electromagnetic radiation received by the subject.

Abstract: It is a system for supplying power to at least one load. The system comprises at least one power source, load bank and control device coupled to the at least one load. The load bank is coupled to at least one power source and at least one load. The load bank comprises a controllable voltage source, at least three resistors coupled between an output side of the controllable voltage source and the at least one power source, and at least one storage element. The controllable voltage source comprises more than one switches. And the at least one storage element comprises one or more capacitors, batteries, or combinations thereof. The control device is configured for controlling the switches during a first condition such that, to the extent that an output power of the at least one power source exceeds a requisite power of the at least one load, any excess output power is either supplied to the at least one storage element or consumed by the at least three resistors.

Abstract: An example data storage system includes a number of storage devices, and processing circuitry. The processing circuit may implement a redundant array of independent disks (RAID) volume using the storage devices, determine an estimated read wait time for each of the storage devices, sort the estimated read wait times into bins of a specified set of bins, and associate bin numbers with the storage devices based on the bins of their respective estimated read wait times.

Abstract: A power integrated system includes a gas storage unit, a gas driven generator, a power bus, a drilling rig, oil/gas production equipment, and a gas reformer. The gas storage unit is used for storing natural gas. The gas driven generator is used for generating electric power based on the stored natural gas. The power bus is used for receiving the electric power generated by the gas driven generator. The drilling rig is used for being driven by the electric power from the power bus. The oil/gas production equipment is used for being driven by the electric power from the power bus and for generating associated gas. The gas reformer is used for reforming the associated gas and supplying the reformed gas to the gas storage unit.

Abstract: A power semiconductor device is comprised of a plurality of zones having similar structure. Each of the zones may be characterized by a switching loss during transitions to a non-conducting state. The device is configured such that the switching loss is different between at least two of the zones. Further, the device is configured such that zones having greater switching losses transition to the non-conducting state before zones having lesser switching losses.

Abstract: Paper-based single cell arrays are provided, as well as methods of making and using the arrays. The invention provides a low cost, high-throughput platform to detect and quantify different types of DNA damage at point-of-care without expensive equipment or highly trained personnel. Ordinary paper can be covered with multiple layers of common printing ink and micro-patterned to form discrete and ordered arrays capable of binding a single cell, which are then lysed and imaged. The platform allows quick and inexpensive testing of multiple anti-cancer treatment options for a particular patient. The invention can make cancer treatment personalized and more effective, even in low-resource settings.

Abstract: A power inverter includes a plurality of power modules stacked in an array. A plurality of coolant chambers are interleaved with the modules. Each of the chambers includes an inlet and an outlet interconnected by a coolant path configured to circulate coolant within the chamber. Fins project into the coolant path and are configured to alter shape based on a temperature of the coolant to alter a turbulence associated with the coolant.

Abstract: A high capacity nanoparticle-based covert barcode system relies on an entirely optical readout for detection. The system includes a panel of phase change nanoparticles with sharp and discrete melting peaks; readout is based on heating with an infrared source and detection using an infrared imager, and detection of their phase transition temperatures and positions. A readily detectable and sudden change in temperature occurs at the phase transition during a heating or cooling process, and can be used to indicate the identity of nanoparticles.
