Abstract: A contactless, three-dimensional fingerprint scanner apparatus, method, and system are described. The contactless fingerprint scanner can provide either, or both, topographical contrast of three-dimensional fingerprint features and optical contrast of a three-dimensional fingerprint surface. Data captured from scanning of a target with known geometric features mimicking fingerprint features can be examined as images or surface plots and analyzed for fidelity against the known target feature specifications to evaluate or validate device capture performance as well as interoperability. The target can be used by scanner vendors and designers to validate their devices, as well as to perform type certification.

Abstract: A multiplex polymerase chain reaction assay that targets nine tetranucleotide short tandem repeat (STR) markers in the mouse genome. Unique profiles were obtained from seventy-two mouse samples that were used to determine the allele distribution for each STR marker. Correlations between allele fragment length and repeat number were determined with DNA Sanger sequencing. Genotypes for L929 and NIH3T3 cell lines were shown to be stable with increasing passage numbers as there were no significant differences in fragment length with samples of low passage when compared to high passage samples. In order to detect cell line contaminants, primers for two human STR markers were incorporated into the multiplex assay to facilitate detection of human and African green monkey DNA. This multiplex assay is the first of its kind to provide a unique STR profile for each individual mouse sample and can be used to authenticate mouse cell lines.

Abstract: A method for detecting a two-qubit correlated dephasing error includes accessing a signal of a quantum system, where the quantum system includes a plurality of qubits. Every qubit has a nonzero rate of dephasing and some qubits have a nonzero rate of correlated dephasing. The signal further includes information about a matrix that includes diagonal elements and off-diagonal elements. The off-diagonal elements of the matrix are 2s-sparse. The method further includes performing randomized measurements of the off-diagonal elements of the matrix and recovering the matrix based on a direct measurement of the diagonal elements of the matrix.

Abstract: Exemplary embodiments include buried electrodes that allow for bottom electrode integration with photonic devices, while retaining the ability to perform the high-temperature processing steps used in low-loss photonic elements. In addition to functionality in the case of buried heaters for thermal tuning of devices, the same or similar techniques can be applied to other tuning mechanisms, based on the electro-optical effect and (piezoelectrically-mediated) stress-optical effect.

Abstract: A system for generating a coherent laser light includes a light source configured to pump a first color laser light and a device configured to generate a coherent second color light and a coherent third color light. The device includes a waveguide configured to couple to the light source and a microring resonator coupled to the light source via the waveguide. The microring resonator is configured to generate a coherent second color light and a coherent third color light. The generation of the coherent second color light and the coherent third color light is based on hybrid-mode optical parametric oscillation.

Abstract: An example electric circuit includes a superconductor component having a first terminal at a first end and a second terminal at a second end. The superconductor component includes a first portion coupled to the first terminal, a second portion coupled to the second terminal, and a third portion coupling the first portion and the second portion. The third portion has a curved shape such that the first portion of the superconductor component is proximate to, and thermally coupled to, the second portion of the superconductor component. The example electric circuit further includes a coupling component coupled to the third portion of the superconductor component, and a gate component configured to generate a resistive heat that exceeds a superconducting threshold temperature of the superconductor component, where the gate component is separated from the superconductor component by the coupling component.

Abstract: A biomarker signal amplifier amplifies chemical analyte binding and includes: a surface strand disposed on an analysis substrate and including an exchange region; a particle strand hybridized to the surface strand in an absence of a chemical analyte that preferentially hybridizes to the exchange region as compared with the particle strand, and the particle strand is dissociated from the surface strand when the surface strand is in a presence of the chemical analyte; and a reporter particle attached to the particle strand and disposed proximate to the analysis substrate when the particle strand is hybridized to the surface strand in absence of the chemical analyte and that changes the electrical potential of the analysis substrate depending on whether the particle strand is hybridized to the surface strand.

Abstract: Embodiments of the present invention relate to a system and method for performing temperature-dependent measurements of a magnetic nanoparticle sample. The system includes high frequency coils and sample temperature tunable assembly to determine the specific relaxation process for magnetic nanoparticle sample using both time and frequency domain techniques. During the temperature-dependent measurements of a magnetic nanoparticle sample, system in accordance with embodiments of the present invention resolve the nanoparticle dynamics using a temperature-tunable dual mode, AC susceptibility and magnetic relaxometry, to cover a broad range of frequencies and time scales. Other operational modes of the invention can drive the nanoparticles with arbitrary waveforms (sinusoidal, sum of sinusoids, or repeated pulses) to elicit and measure tailored response behavior from the magnetic nanoparticle sample.

Abstract: A passively protected quantum memory in two dimensions includes: a square lattice of harmonic oscillators; each of the harmonic oscillators experiencing a coherent two-photon drive process and an incoherent two-photon loss process; each of the harmonic oscillators coupled to its nearest neighbor harmonic oscillator via a ferromagnetic Ising parity-parity interaction, which can be realized, for example, by coupling LC oscillators with a Josephson junction; and a cold bath coupled to the harmonic oscillators at a temperature such that parities of neighboring harmonic oscillators align through an energy dissipation process.
