摘要： A laser device includes a gain medium including a facet. The laser device includes a metasurface including a plurality of supercells. The metasurface is disposed on a substrate and configured to reflect and focus a first portion of light from the facet back to the gain medium as a feedback beam. The metasurface can be configured to reflect a second portion of the light as an output beam at an angle that is nonzero relative to a direction of the feedback beam. The metasurface can be configured to transmit a second portion of the light as an output beam through the metasurface away from the facet. The emission wavelength of the laser device can be tuned by translating the metasurface. The output beam can be collimated towards a fixed direction while tuning the wavelength.

摘要： A magnetic resonance imaging (MRI) system can include a magnetic resonance imaging (MRI) scanner, having a plurality of radio frequency (RF) receivers, and a processor. The MRI scanner can perform a full field of view (fFOV) scan on an anatomy area including an implant to acquire first multi-spectral MRI data associated with a plurality of frequency bins. The processor can generate, for each pair of a single RF receiver and a single frequency bin, a respective spectral sensitivity map using at least a portion of the fFOV multi-spectral MRI data. The MRI scanner can perform a reduced FOV (rFOV) scan to acquire second multi-spectral MRI data associated with the plurality of frequency bins. The processor can reconstruct one or more MRI images according to the rFOV using the rFOV multi-spectral MRI data and the spectral sensitivity maps.

摘要： Provided herein are systems and methods for defining and securely sharing objects for use in preventing data breach or exfiltration. Memory may be configured to store a plurality of objects for use in preventing data breach or exfiltration. A validation engine can validate the objects, incorporate into each object an object identifier and a signature, and generate a subset of the objects for use by a first user. The validation engine can store, in the memory, the plurality of objects as a superset of objects corresponding to the generated subset. An evaluation engine may, responsive to identifying that one or more object identifiers and signatures in a received set of objects belong to the subset corresponding to the stored superset, verify whether any object in the received set has been tampered with.
