Abstract: The electrothermal “3 omega” technique is used to monitor thermal signatures on a battery cell during charge cycling. Changes in first and third harmonic voltages are measured during cycling and potential causes are identified. When a shorter-term moving average of the resistance thermography 3ω voltage on one or more of a plurality of frequency bands deviates from a longer-term moving average of the resistance thermography 3ω voltage by more than a predetermined threshold, starting and controlling an alarm process can include replacing the battery cell. This work shows the potential of the 3 omega technique to quickly detect signs of cell failure during operation.

Abstract: Devices employing Brillouin interactions that can be modified by acoustoelectric (AE) interactions, thereby enabling control over the devices' nonlinear optical susceptibility, are described. Modification of the phonon dissipation rates through application of quasistatic electric fields in the semiconductor can improve the performance of Brillouin photonic devices. These AE Brillouin interactions allow for local control of the phonon phase velocity and thus the Brillouin scattering frequencies, providing an electronic means to compensate for inhomogeneous broadening that occurs over large length scales. Moreover, these AE Brillouin interactions allow Brillouin scattering processes to employ phonon coherence lengths that can achieve parity with and even exceed those of the photons, enabling fully coherent three-wave parametric-like processes. Devices in accordance with various aspects of the present invention have simultaneously demonstrated, using these effects, both large optomechanical confinement and coupling, and AE coupling.

Abstract: A system and method for designing a physical system using a genetic algorithm includes building a plurality of data structures necessary to build, heal, and verify a plurality of dependency chains; ensuring that multiple dependencies in a respective one of the plurality of dependency chains are represented correctly; removing any dependencies that will be trivially satisfied at random; in response to determining that one or more dependencies is consistent with another dependency, considering one or more combinations of dependencies; and building configurations that satisfy the dependencies and combinations of dependencies by associating the dependencies and combinations of dependencies with selected technology options and recursively specifying and/or revising additional technology options that are consistent with the dependencies or combinations of dependencies, until a configuration is fully specified.

Abstract: The present disclosure is directed to systems, methods and tools that measure ionic concentrations and downhole enthalpy of a flowing geothermal fluid in real-time at high-temperature and pressure. The systems, methods and tools include measuring the concentration of selected naturally occurring ions found in the liquid phase of the geothermal fluid throughout the wellbore using novel electrochemical sensor technologies. The change in liquid-phase ion concentration will be used to calculate the proportion of liquid to steam and allow for accurate enthalpy measurements. The techniques and technologies described here can be applied to any application of electrochemical sensing in extreme environments.

Abstract: Digital image segmentation is provided. The method comprises training a neural network for image segmentation with a labeled training dataset from a first domain, wherein a subset of nodes in the neural net are dropped out during training. The neural network receives image data from a second, different domain. A vector of N values that sum to 1 is calculated for each image element, wherein each value represents an image segmentation class. A label is assigned to each image element according to the class with the highest value in the vector. Multiple inferences are performed with active dropout layers for each image element, and an uncertainty value is generated for each image element. Uncertainty is resolved according to expected characteristics. The label of any image element with an uncertainty above a threshold is replaced with a new label corresponding to a segmentation class based on domain knowledge.

Abstract: Coupling qubits is provided. The method comprises embedding a tin atom in a silicon substrate and forming a number of quantum dot electrodes over the silicon substrate. The quantum dot electrodes draw an electron from an electron source into the silicon substrate and performing an electron-nuclear controlled-phase gate operation by: moving the electron adiabatically toward the tin atom to achieve a specified level of hyperfine interaction (HFI) between the electron and the nucleus of the tin atom to minimize the effect of noise; holding the electron at the distance of the specified HIFI for a specified duration of time to represent an “on” state; and moving the electron adiabatically away from the tin atom to lower the HFI below the specified level and represent an “off” state

Abstract: A fluid flow control device comprising an insert body having a first portion with a first permeability and second portion with a second permeability that is different from the first permeability. The insert body can be shaped for sealing insertion into a fluid flow structure for fluid flow therethrough. The first portion and the second portion can be arranged in the insert body to cause uniform fluid flow velocity of fluid in the fluid flow structure at an exit of the insert body when the fluid passes through the first portion and the second portion when the insert body is placed inside the fluid flow structure.
