Abstract: Various embodiments of the present invention are directed toward systems and methods relating to security screening. For example, a screening system includes a chamber configured to accommodate a user to be screened, and a chamber scanner. The chamber scanner is configured to scan the user to identify whether the user is carrying an undivested item that needs to be divested. The chamber is configured to release the user to proceed from the chamber to a secure area, upon confirmation that no undivested items are to be divested.

Abstract: A flow imaging and monitoring system for synchronized management of wide area drainage that includes an interposer for supporting monitoring and management equipment in a manhole, a module for illuminating water flowing in pipes at the base of the manhole, a module for monitoring responses to reflected light, a sealed and rechargeable battery pack, and a data analysis and management system to interpret data streams in real time. The interposer can be adjusted to fit the diameter of the manhole and can be adjusted to be placed under the manhole cover. The module for illuminating the flowing water can be adjusted to generate various frequencies. The support structures for the modules can be adjusted for varying pitch, roll and yaw with respect to the manhole. The data analysis and management system is supported by cloud computing.

Abstract: Systems and methods of detecting a vortex made by a travelling object is disclosed. Techniques include positioning a media collector to capture a visual media file of the vortex. In some configurations, a graphic recognition algorithm and vortex similarity engine are used to determine whether a visual media file captured by a media collector contains a vortex. In some configurations, a computer may trigger an alert if a travelling object vortex is not expected to be in the visual media file.

Abstract: Disclosed herein is a method and thermoset made by: reacting a di- or tri-functional isocyanate with a silyl-containing compound to form a polyurethane having at least one unreacted isocyanate group, reacting the polyurethane with an aminoalkylalkoxysilane to form an alkoxysilane-terminated polyurethane, and moisture-curing the alkoxysilane-terminated polyurethane to form the thermoset. The silyl-containing compound has the formula: SiR1n[R3—(O—CO—X—R3)m—OH]4-n. Each X is —O— or —NR2—; each R1 is an alkyl group or an aryl group; each R2 is —H, an alkyl group, or an aryl group; each R3 is an alkylene group; n is 0, 1, or 2; and each m is a non-negative integer. The thermoset may be degraded by treatment with a solution of a fluoride salt in an organic solvent.

Abstract: Heterostructures include a layer of a two-dimensional material placed on a multiferroic layer. An ordered array of differing polarization domains in the multiferroic layer produces corresponding domains having differing properties in the two-dimensional material. When the multiferroic layer is ferroelectric, the ferroelectric polarization domains in the layer produce local electric fields that penetrate the two-dimensional material. The local electric fields modulate the charge carriers and carrier density on a nanometer length scale, resulting in the formation of lateral p-n or p-i-n junctions, and variations thereof appropriate for device functions.

Abstract: A supported heterogeneous catalyst material for catalyzing the reverse water-gas shift (RWGS) reaction for the selective formation of CO using an alkali metal-doped molybdenum carbide on a gamma alumina support (A-Mo2C/?-Al2O3, A=K, Na, Li). The A-Mo2C/?-Al2O3 catalyst is synthesized by co-impregnation of molybdemun and alkali metal precursors onto a ?-Al2O3 support. It is then carburized to form the A-Mo2C/?-Al2O3.

Abstract: A substrate is printed with front side and back side markings in a first color ink. The front side when viewed with reflected light includes a first marking printed in a first saturation and a first symbol printed in the first saturation. The back side when viewed with reflected light includes: a second marking printed in a second saturation; a second symbol printed in the second saturation; a third marking printed in the first saturation; and a third symbol printed in the first saturation. The first marking, the second marking, and the third marking are printed to provide an interlocking pattern of low saturation color and high saturation color when viewed with transmitted light. The second symbol is visible, and the first symbol and the second symbol are not distinguishably visible, when viewed with transmitted light.

Abstract: High-performance optical-metasurface-based components configured to at frequencies of UV light and, in particular, in deep UV range and performing multiple optical-wavefront-shaping functions (among which there are high-numerical-aperture lensing, accelerating beam generation, and hologram projection). As a representative material for such components, hafnium oxide demands creation and establishment of a novel process of manufacture that is nevertheless based on general principles of Damascene lithography, to be compatible with existing technology and yet sufficient for producing high-aspect-ratio features that currently-used materials and processes simply do not deliver. The described invention opens a way towards low-form-factor, multifunctional ultraviolet nanophotonic platforms based on flat optical components and enabling diverse applications including lithography, imaging, spectroscopy, and quantum information processing.

The first and second set of channels are arranged so that application of a voltage differential between the positive electrodes and the negative electrodes generates an attractive force between each set of adjacent positive and negative electrodes.

Abstract: Methods, and systems, for Multiagent Pathfinding for Non Dynamic Programming Problems, including a CE method which provides for sampling from a complex probability distribution that is not necessarily known in a closed form. The applications of this method include rare-event simulation, variance reduction for estimation problems, and stochastic optimization. The method iteratively searches for a probability distribution that is “close” to the intended distribution, where the closeness of distributions is measured using the Kullback-Liebler (KL) divergence between the distributions. At each step, the method generates samples according to a current candidate distribution from the family. Next, it uses those current candidate distribution samples to move the distribution toward a new candidate distribution that is closer in the sense of KL divergence to the target distribution.
