Abstract: Systems and methods for radiolocation using backscatter RFID tags and a special-purpose reader that produces a SFCW RF interrogation signal comprising N carrier frequencies. A backscattered interrogation signal from a backscatter RFID tag is down-converted using at least a portion of the generated SFCW RF interrogation signal. RSP corresponding to the N carrier frequencies are determined. RSS may be determined to improve performance. A distance between the RFID reader and the backscatter RFID tag may be estimated based on at least a summation of differences between RSPs corresponding to adjacent carrier frequencies.

Abstract: A computer-implemented system uses multiscale modeling and optimization algorithms to design DNA nanostructures that self-assemble into a target structure, such as a tetrastack lattice. The system converts a target structure into a Boolean Satisfiability problem and models nanostructure units as “patchy” nanostructure models, where patches encode kinetic properties that affect how each nanostructure model connects with other nanostructure models. The system iteratively simulates self-assembly of a plurality of nanostructure models into a nanostructure assembly model, and compares the nanostructure assembly model with the target structure to determine a set of optimal parameters (such as patch type assignments) for the nanostructure units that reliably result in self-assembly into the target structure.

Abstract: Systems and methods are disclosed for radiolocation using backscatter RFID tags and a special-purpose reader that produces a stepped-frequency continuous wave (SFCW) radio frequency (RF) interrogation signal comprising N carrier frequencies. A backscattered interrogation signal from a backscatter RFID tag is down-converted using at least a portion of the generated SFCW RF interrogation signal. Received signal phases (RSP) corresponding to the N carrier frequencies are determined. Received signal strength (RSS) may be determined to improve performance. A distance between the RFID reader and the backscatter RFID tag may be estimated based on at least a summation of differences between RSPs corresponding to adjacent carrier frequencies.

Abstract: A sensor comprises a plurality of sensor elements arranged in an array. Each sensor element is memristive and has an electrical resistance characteristic related to exposure to a species to be sensed. The sensor elements are arranged to be connectable such that at least one sensor element is connected in parallel with at least one other sensor element. By using appropriate connections, the array of sensor elements can be read.

Abstract: A system and method to monitor and control heart rhythms using ultrasonic signals, including providing pacing and defibrillation therapy, are provided. A device for monitoring and controlling heart rhythms includes an intra-cardiac implantable device having an ultrasonic transducer to receive and/or transmit ultrasonic signals, and pacing circuitry to convert an acoustic signal into an electrical signal to stimulate or control a cardiac rhythm

Abstract: A process for producing PHA comprises obtaining biomass produced in the course of biologically treating a first wastewater source containing RBCOD. The biomass is to be exploited with a second wastewater source having a different RBCOD content from the first wastewater source in order to accumulate and thereby produce PHA. Before subjecting the biomass to a PHA accumulation process, the biomass PHA accumulation potential is enhanced via an acclimation process with the second wastewater source. During acclimation, the biomass is subjected to repeated feast-famine periods. During each feast period, the biomass is exposed to a fraction of the second wastewater source. The RBCOD uptake and/or biomass respiration rate is directly or indirectly measured during each feast period. The famine period is maintained for a period of time that is at least two times greater than the length of time of the proceeding feast period. After at least two feast-famine acclimation periods or after one or more measured parameters reveal an increased RBCOD relative uptake or respiration rate of the biomass during a subsequent feast period, the biomass is subjected to a PHA accumulation process using the second wastewater source.
