Abstract: A method for promoting continuous sleep of a subject by eliminating and/or preventing sleep associations includes: (a) providing an apparatus including at least one sensor and at least one output device; (b) monitoring a state of the subject using the apparatus; (c) determining the subject is in an awake state using the at least one sensor; (d) in response to determining the subject is in the awake state, initiating and maintaining an output using the at least one output device; (e) determining the subject is in a sleep state using the at least one sensor; (f) halting the output in response to determining that the subject is in the sleep state such that the apparatus does not produce any output; (g) repeating at least step (b) during a sleep session. The method further includes modifying an intensity of the output over time until the intensity reaches zero.
Abstract: A retinal vessel shadow view optical coherence tomography (RVSV-OCT) image can be created by receiving, at an enhanced OCT processing system, volumetric OCT scan of a patient. The system can segment the volumetric OCT scan to determine layer boundaries and delineate a boundary of interest based on the determined layer boundaries of the segmented volumetric OCT scan. En face vascular information can be extracted to create an RVSV-OCT image by determining a first offset from the boundary of interest and a second offset from the boundary of interest; extracting volumetric data from an area between the first offset and the second offset to create a three-dimensional volume; and identifying a two-dimensional surface from the three-dimensional volume, the two-dimensional surface being the RVSV-OCT image. The RVSV-OCT image can be provided for analysis, for example, to evaluate retinal vascular disease in preterm infants at risk for retinopathy of prematurity.

Abstract: The present disclosure describes techniques for optimizing two-qubit gates performance in a quantum circuit of a quantum computing system. A quantum computing system selects, from qubits in the quantum circuit, a pair of target qubits on which to perform a quantum gate operation. The quantum computing system selects, from the plurality of qubits, a second plurality of qubits on which to introduce an intentional noise. The intentional noise is applied to the second plurality of qubits via a numerical optimizer. An optimized frequency is determined based on the applied intentional noise. The quantum gate operation is performed by modifying the pair of target qubits frequency to the optimized frequency.
Abstract: A drainage or infusion catheter and methods of use are disclosed. In one embodiment, the catheter includes a tube body having a proximal end and a distal end, and a plurality of ports arranged along the tube body from the distal end to the proximal end. The distal end of the tube body is configured to deform around itself into a substantially spiral shape so as to cover at least one of the plurality of ports located near the proximal end of the tube body. In another embodiment, a flap is configured to erupt from apertures arranged in the tube and extend outwardly around the tube body so as to cover at least one of the plurality of ports located near the proximal end of the tube body.
Abstract: Systems and method for multiplexing and alternating light of different wavelengths in an ophthalmoscope are disclosed herein.

Abstract: A system includes a controller configured to reconstitute a continuous waveform to a discrete analogue version. The system includes a numerical optimizer configured to determine frequencies of a pulse sequence. The numerical optimizer uses radial motional mode frequencies and a desired gate time. The numerical optimizer generates the pulse sequence by closing phase-space trajectories, disentangling spins and motions, and constraining a Rabi frequency for motional sideband transitions. The system also includes a display configured to illustrate a discrete frequency modulation pulse sequence based on the determined frequencies.
