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.

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.

Chemical wave systems that utilize chemical compounds with nonlinear chemical wave behavior can be used to detect or sense material changes such as a change in a radiation source. Such chemical systems include autocatalysis that produce self-sustaining spatial and/or temporal fluctuations in chemical attributes such as species concentrations, pH, and/or redox state. Through application of the chemical compounds with wave behavior into engineered geologic environments, such as those for containment of a liquid or solid, the chemical wave behavior may be triggered or modified by perturbations, including intrusion into the environment. The chemical wave behavior is an indicator of the said perturbation and monitored by various means tailored to the type of chemical waves. The chemical waves can have a type of “fingerprint” based on their wave behavior that lasts beyond a transient disturbance that could later be discerned by measurement of the chemical wave attributes.

Based on the determined scattering and absorption coefficients, the signal incident on the detector may be calculated. The calculation may also be inverted such that based upon the detected signal, an object may be detected, and its location in the scattering medium may be estimated.

Encoding terrain maps is provided. The method comprises receiving a digital elevation model (DEM) of a terrain and encoding the DEM into grid cells parameterized by spatial scale, orientation, and 2D offset. Grid cells with shared scale and orientation are aggregated into grid modules. Locations from the DEM that correspond to a given elevation produce a contour line of locations that fall within the given elevation. 2D phase codes are calculated for each grid module to produce a phase candidate dictionary, wherein a subset of phase codes comprises phase candidates corresponding to locations from the contour line. When sensor data is received along a trajectory over the terrain, the phase candidate dictionary is queried. Phase candidates are corrected for relative displacement from a reference point and summed to produce a coincidence map over the DEM that identifies a current location estimate over the terrain.

A method and system architecture for designing a compressive sensing matrix for machine learning includes receiving an image associated with a classification task and; generating a sensing matrix. The sensing matrix includes an array of nonzero elements of the image. A prism array of prism elements is in communication with the sensing matrix. A row of values corresponding with an input angle of the prism array is mapped to a respective column corresponding with a detector. Then the detector detects light refracted at an output angle dictated by the physical shape of the prism element. A physical model of the detector is fabricated and generates a compressed representation of the image. A machine learning classification algorithm is applied to the compressed representation of the image and generates an optimized non-invertible final determination of the image.

Abrégé
A large and highly diverse nanobody library was constructed and screened against multiple variants of SARS-COV-2 to find nanobodies with high sensitivity and specificity for the variants. Four rounds of positive selection against a panel of six diverse SARS-COV-2 variant RBDs was performed with our high-diversity. At least 59 of these nanobodies were found to work well against Alpha, Beta, Gamma, Delta, Kappa, Lambda and Mu with some overlap efficacy against other variants. These nanobodies have efficacy as stand-alone nanobodies and as a construct comprising nanobodies linked to the human IgG1 constant fragment (Fc) (nanobody-hFc constructions or nb-hFcs) to make enhanced humanized sdAbs with all the attributes of nanobodies with improved half-life and optimized effector functions. Several promising nanobodies that neutralize the original SARS-COV-2 and several of its variants have been identified, including Delta, with high efficacy. In particular, a subset of these nanobodies bind to the Omicron RBD.

A method for direct write printing of an electrical or optical element based upon a generated master actual position map and a master expected position map is disclosed. The generated master actual position map is generated by efficiently stitching together a number of images using a hierarchical stitching process. Once the desired location of the electrical or optical element is determined by comparing the master actual position map with the master expected position map, a corresponding toolpath for a direct write printer is generated. The direct write printer then direct write prints the electrical or optical element using the generated toolpath. By using different types of inks, the electrical element may be a trace, a resistor, an inductor, a transformer, a capacitor, or some combination thereof. In like manner, the optical element may be a waveguide, a beam-splitter, a phase shifter, an optical attenuator, an interferometer, or some combination thereof.

A pixelated electronic sensor is disclosed for imaging from infra-red to ultraviolet wavelengths, composed of a CMOS integrated circuit plus layers of nano-materials monolithically integrated via low temperature post-processing. Co-design, simulation, and integration methods for the device are described. Each pixel has color-resolved single photon sensitivity without dark counts and without inefficiency. The device operates at temperatures above 70° Kelvin. Current state of the art imagers that can color-resolve single photons are of bolometric or filter type. Bolometric devices must operate at temperature below 1° Kelvin and are limited to few pixels. Devices that use filters are inefficient as all the photons rejected by a filter are wasted. Single photon imagers that operate at non-cryogenic temperature (like Silicon Photomultipliers) have large dark counts typically measured in MHz/cm2. Imaging applications include astronomical telescopes, exoplanet imaging, distant galaxy imaging, microscopic imaging, medical devices, and hyperspectral imaging.

An ionogel is formed by mixture of precursors, a catalyst, and an ionic liquid to form a sol-gel. The precursors and the catalyst react to form a solid-phase matrix that includes pores, wherein the ionic liquid is disposed within the pores. The gel is dried by way of thermal or vacuum drying to remove liquid byproducts of the precursor-catalyst reaction and to form a solid-state ionogel that comprises the solid-phase matrix with the ionic liquid disposed therein. The ionogel is immersed in a quantity of a liquid electrolyte that is soluble in the ionic liquid. As the liquid electrolyte dissolves into the ionic liquid, the ionic liquid is displaced by the liquid electrolyte, yielding an ionogel having the liquid electrolyte disposed within its pores.

Advanced Distribution Management Systems not generally optimize over the entire feeder because there are few high-fidelity distribution circuit models and real-time distribution-connected sensors are rare. The limited observability at the distribution level makes it difficult to globally optimize distribution operations and issue control setpoints to power systems equipment or Distributed Energy Resources (DER) to perform grid-support services. For example, setpoints can be issued to DER based on results from an optimization module that incorporates a static or time-series feeder simulation. Feeder simulation initial conditions are populated with photovoltaic (PV) and load forecasts, state estimation results, and/or digital twin measurements or state output. The real-time (RT) digital twin runs a model of the feeder to generate state estimation pseudo-measurements since there are limited live feeder measurements.

Systems and methods for optical measurement of cross-wind

Inventeur(s)
Bagwell, Brett
Abrégé
Various technologies pertaining to optical measurement of cross-wind are described herein. A beam of light is emitted along a trajectory through a shooting space from a location of a shooter to a target using a laser. The beam is reflected by the target, and the beam is received at two optical detectors. Due to changes in the index of refraction of air along the path of the beam, an envelope signal atmospherically encoded on the beam is received at each of the two apertures at different times. A signal analyzer receives a signal from each of the detectors and outputs data indicative of an average speed of the cross-wind along the trajectory in the shooting space based upon a time delay between the signals.

Rare earth (RE) superhydrides exhibit high temperature superconductivity but are difficult to characterize and use in applications due to their high formation and stability pressures, which are typically in excess of 100 GPa. Cryomilling of metal precursors improves hydrogen reactivity and hydrogen uptake for forming such metal hydrides at lower pressures. As an example, an elemental lanthanum precursor was milled at liquid nitrogen temperatures for different time intervals. After exposure to gaseous hydrogen at 380° C. and 100 bar, a systematic enhancement of hydrogen absorption with increasing ball milling time was found for forming the LaHx, x=2-3 phase. Exposing the La precursor to pressures up to 60 GPa with an ammonia borane (BNH6) hydrogen source resulted in a hypervalent LaH4 phase. This LaH4 phase is associated with the suppression of a rhombohedral distortion of the Fm3m cubic structure after cryomilling the precursor.

Abrégé
A photon-number-resolving detector comprises a detection element, an ohmmeter, and a hardware logic component. The detection element can be formed from a Weyl or Dirac semimetal. Electrons of the detection element are characterized by a surface state that exhibits a Dirac cone and a bulk superconducting state that exhibits a bandgap. When photons having energies less than the bandgap of the bulk superconducting state impinges on the detection element, the photons can be absorbed by electrons of the detection element that are characterized by the surface state. The ohmmeter outputs resistance data indicative of an electrical resistance of the detection element while the photons impinge on the detection element. The hardware logic component can determine, based upon the resistance data, a number of the photons that are absorbed by the surface state electrons of the detection element.

Abrégé
A guided cold-atom inertial sensor system comprises an atom trap integrated platform, a laser system, a magnetic field system, a control system, and a computing system. The laser system and magnetic field system are adapted to form a magneto-optical trap (MOT) about a suspended waveguide of the atom trap integrated platform made of membrane integrated photonics. After loading cold atoms from a MOT, the photonic atom trap integrated platform generates one-dimensional guided atoms with an evanescent field optical dipole trap (EF-ODT) along the optical waveguide to create guided atomic accelerometers/gyroscopes. Motion of atomic wavepackets in a superposition state is created along the guided atom geometry by way of state-dependent momentum kicks. The light-pulse sequence of guided atom interferometry splits, redirects, and recombines atomic wavepackets, which allows measurement of atom interference fringes sensitive to inertial forces via a probe laser.

Abrégé
A system and a method for the remote monitoring of an irradiated salt mass within a decay enclosure is provided. The system and the method determine a mass ratio of a first radioisotope relative to a second radioisotope, the second radioisotope having a significantly shorter half-life than the first radioisotope. In addition, the second radioisotope includes a shorter half-life than an effective half-life of the decay enclosure, and the first radioisotope includes a longer half-life than the effective half-life of the decay enclosure. The mass ratio quickly decreases outside of a target range after material diversion, while remaining below the target range for several years. As a consequence, the isotopic mass ratio presents a rapid and enduring indicator of inventory change, which is of extreme importance in detecting a diversion of the irradiated salt mass, which remains a potential proliferation target.

Abrégé
A single photon radiation detector is designed for a particular radiation source fluence, such that an incident radiation photon strikes a scintillator monolith, creating scintillation photons, which are amplified by appropriately sized channels of photomultipliers optically coupled to the scintillator monolith. The photomultiplier output is electronically shaped into a corresponding stream of scintillation pulses (otherwise referred to as scintillation photons) that pass through a comparator to produce a bitstream of the detected scintillation photons, which is sampled into a field programmable gate array (FPGA) acting as a giga-sample transceiver to produce time-to-digital conversions, capable of producing an output data stream of 10's-of-giga-samples per second or more. Appropriate design ensures sparsity of scintillation photon arrival, so that each photon in the bitstream corresponds to a single incident scintillation photon.

Abrégé
A maze-based switch generally having three functional blocks is disclosed. The first functional block handles communications by accepting an entered maze pattern from an external system controller and outputting the entered maze pattern (and optionally its directional complement) to the second functional block. The second functional block stores the maze pattern (and optionally its directional complement) to a permanent storage element and outputs the stored, entered maze pattern and its directional complement to a series of transistors in the third functional block. The third functional block is an electronic maze in which a correct maze pattern and its directional complement must be received by the transistors for the transistors to pass electrical power through the electronic maze to a connected element. The third functional block may alternatively be implemented with optical elements, optoelectronic elements, microelectromechanical elements, or elements formed by other microsystem technologies.
