Abstract: Aspects of the present disclosure describe systems, methods, and structures for aberration correction of optical phased arrays that employ a corrective optical path difference (OPD) in the near-field of an OPA to correct or cancel out aberrations in emitted beams of the OPA including those reaching far-field distances by generating a spatially-varying OPD across the aperture of the OPA that is substantially equal and opposite to an equivalent OPD of the aberration(s).

Abstract: An event detection unit (EDU) for detecting an explosive event is provided. The EDU includes different types of sensors for measuring characteristics of an explosive event. The EDU includes an event notification component. The EDU also includes a processor that receives a measurement from the sensors and generates a combined non-event probability and a combined event probability based on that measurement that indicates a likelihood that an explosive event has not occurred or has occurred. The processor determines whether an explosive event has occurred based on the non-event probabilities and event probabilities. When an explosive event has been determined to occur, the processor directs the event notification component to output a notification that an explosive event has occurred.

Abstract: Techniques for generating a dosing protocol for an individual include receiving first data that indicates, for a dose response to a medicament, a non-linear mixed effects (NLME) model of a population with at least one distribution parameter characterizing variations in the population based on an observable property of individuals within the population. At least one of a structural model or a dynamical model of the NLME model is based on training weights of a universal approximator on a least a subset of the population. A candidate dose regimen is evaluated for an expected response by a subject based on the NLME model and one or more properties of the subject. When the expected response is therapeutic, the candidate dose regime of the medicament is administered to the subject.

Abstract: Methods, systems, and devices for input/output line sharing for memory subarrays are described. I/O lines may be shared across subarrays, which may correspond to separate memory tiles. The sharing of I/O lines may allow an I/O line to carry data from one subarray in response to access commands associated with one address range, and to carry data from another subarray in response to access commands associated with another address range. In some cases, sense amplifiers and other components may also be shared across subarrays, including across subarrays in different banks. The sharing of I/O lines may, in some cases, support activating only a subset of subarrays in a bank when accessing data stored in the bank, which may provide power savings.

Abstract: Light is provided to optical antennas (OAs) separated by a first set of spacings in a first OPA. Phases of light provided to respective OAs are controlled to form a transmitted beam whose angle is steered so that first and second lobes of a first angular intensity distribution (AID) scan over first and second portions of a region, respectively. Light is received from OAs separated by a second set of spacings in a second OPA into which light is received from directions associated with a second AID. The first lobe of the first AID and a first lobe of the second AID substantially overlap in angle during the scan of the first lobes, and the second lobe of the first AID and a second lobe of the second AID substantially overlap in angle during the scan of the second lobes.

Abstract: Computer-implemented systems and methods for controlling presentation in a web application among remote users over a data network. A web application has a remote control user-interface (UI) element that allows one to turn on or off remote control presentation. Presentation data is shared in the web application among remote users depending on whether the remote control UI element is turned on or off. A system includes an inter-browser controller coupled to the web application. The web application outputs a page having a remote control UI element. The inter-browser controller controls sharing of presentation data selected by a first user through the web application to other remote users depending on whether the remote control UI element is turned on or off.

It is distinguishable from other ornamental sweetpotato cultivars by its palmate, deeply lobed leaves with 3-5 lobes, an aggressive climbing habit, and heavily branched architecture. The chartreuse leaves, long internodes, and the plant architecture, which promotes good plant production in the greenhouse for wholesale distributors, distinguish ‘NCORNSP-028SCKL’ amongst the current ornamental sweetpotatoes in the marketplace. ‘NCORNSP-028SCKL’ exhibits very good vigor and is very well branched. ‘NCORNSP-028SCKL’ is suitable for use in vertical landscape or container plantings.
