Abstract: A laser-assisted microfluidics manufacturing process has been developed for the fabrication of additively manufactured structures. Roll-to-roll manufacturing is enhanced by the use of a laser-assisted electrospray printhead positioned above the flexible substrate. The laser electrospray printhead sprays microdroplets containing nanoparticles onto the substrate to form both thin-film and structural layers. As the substrate moves, the nanoparticles are sintered using a laser beam directed by the laser electrospray printhead onto the substrate.

Abstract: A tactile display device including a nodule having variable stiffness under a surface to provide a near-real feeling of palpation for a physician. The device utilizes granular jamming technology using pneumatic actuation to control a nodule that maintains its shape while allowing the modulation in stiffness. The nodule includes two hemispheres, a contact portion and an actuation portion, forming a sphere. The contact portion and the actuation portion include different thicknesses and/or materials, while the dimensions of the dimensions of the nodule are maintained. As such, a physician can utilize the device to identify the difference between a normal lump and an affected lump even if the shape of each lump appears to be the same. With the tactile display device, due to the different levels of stiffness, a physician can detect the severity of the lump.

Abstract: Cerium oxide nanoparticles (CNPs) have been proven to exhibit antioxidant properties attributed to its surface oxidation states (Ce4+ to Ce3+ and vice versa) mediated at the oxygen vacancies on the surface of CNPs. Different anions in precursor cerium salts were used to prepare CNPs resulting in disclosed CNPs with varying physicochemical properties such as dispersion stability, hydrodynamic size, and the signature surface chemistry. The antioxidant catalytic activity and oxidation potentials of different CNPs have been significantly altered with the change of anions in the precursor salts. For one, CNPs prepared using precursor salts containing NO3? and Cl? ions exhibited increased antioxidant activity than previously thought possible. The change in oxidation potentials of CNPs with the change in concentration of the nitrate and chloride ions indicates the disclosed CNP's have different surface chemistry and antioxidant properties. These compositions and methods of their synthesis are disclosed.

Abstract: Enabling the use of lithium metal as an anode electrode is a key for developing next generation energy storage device beyond current lithium ion battery technology. However, there are major obstacles that need to be overcome before it can be used in commercial applications; specifically, dendrite formation can short the cell, and electrolyte decomposition contributes to decreased battery lifetimes. Each obstacle can be overcome by coating a lithium metal anode with a liquid metal buffer that enables uniform deposition of lithium ions thereon, preventing dendritic growth and forming a stable solid electrolyte interface to separate the lithium metal anode from the electrolyte within a battery cell. The liquid metal buffer becomes a semi-liquid buffer when contributing to forming a solid electrolyte interface, and can regain its liquid state when the lithium ions flow to the cathode of the battery cell.

Abstract: An improved method of performing object segmentation and classification that reduces the memory required to perform these tasks, while increasing predictive accuracy. The improved method utilizes a capsule network with dynamic routing. Capsule networks allow for the preservation of information about the input by replacing max-pooling layers with convolutional strides and dynamic routing, allowing for the reconstruction of an input image from output capsule vectors. The present invention expands the use of capsule networks to the task of object segmentation and medical image-based cancer diagnosis for the first time in the literature; extends the idea of convolutional capsules with locally-connected routing and propose the concept of deconvolutional capsules; extends the masked reconstruction to reconstruct the positive input class; and proposes a capsule-based pooling operation for diagnosis.

Abstract: Covalent organic frameworks (COFs) usually crystallize as insoluble powders and their processing for suitable devices has been thought to be limited. Here, it is demonstrated that COFs can be mechanically pressed into shaped objects having anisotropic ordering with preferred orientation between the hk0 and 00/ crystallographic planes. Pellets prepared from bulk COF powders impregnated with LiClO4 displayed room temperature conductivity up to 0.26 mS cm?1 and stability up to 10.0 V (vs. Li+/Li0). This outcome portends use of COFs as solid-state electrolytes in batteries.

Abstract: A visibly transparent planar structure using a CPA scheme to boost the absorption of a multi-layer thin-film configuration, requiring no surface patterning, to overcome the intrinsic absorption limitation of the absorbing material. This is achieved in a multi-layer absorbing Fabry-Perot (FP) cavity, namely a thin-film amorphous silicon solar cell. Omni-resonance is achieved across a bandwidth of 80 nm in the near-infrared (NIR), thus increasing the effective absorption of the material, without modifying the material itself, enhancing it beyond its intrinsic absorption over a considerable spectral range. The apparatus achieved an increased external quantum efficiency (EQE) of 90% of the photocurrent generated in the 80 nm NIR region from 660 to 740 nm as compared to a bare solar cell. over the spectral range of interest.

Abstract: This invention relates to tracking of hand-held devices and vehicles with respect to each other, in circumstances where there are two or more users or existent objects interacting in the same share space (co-location). It extends conventional global and body-relative approaches to “cooperatively” estimate the relative poses between all useful combinations of user-worn tracked devices such as HMDs and hand-held controllers worn (or held) by multiple users. Additionally, the invention provides for tracking of vehicles such as cars and unmanned aerial vehicles.

Abstract: Methods of detecting and categorizing an action in an untrimmed video segment regardless of the scale of the action and the close proximity of other actions. The methods improve upon the prior art which either require trimmed video segments including only a single activity depicted therein, or untrimmed video segments including relatively few actions, persons, or objects of interest, thereby directing the classification. Instead, the methods utilize a plurality of tubelets used to represent discreet actions, persons, and objects of interest within the comprehensive untrimmed video segment. The tubelets are localized to correct for pixel-level foreground-background biases, which are then turned into short spatio-temporal action tubelets that are passed to a classification network to obtain multi-label predictions. After classification, the tubelets are be linked together to obtain the final detections with varying lengths, and the method merges the short action tubelets into final action detections.

Dependent upon configuration, the device may be employed as a large area resonator to collect weak or diffuse signals or as a constituent of an array able to take pictures within the spectrum for which they are sensitive.

Abstract: Techniques, for secure processing of encrypted data on public resources, include receiving first data indicating a sequence of reversible q-bit gates including a first segment for decrypting, a second segment for operating on the decrypted data, and a third segment for encrypting the resulting data. Second data indicates rules for replacing a first sequence of two gates operating on at least one shared bit of an input N-bit word with a different second sequence of one or more gates that produce the same output N-bit word. The second data is used to propagate: a gate from the first segment a distance into the second segment or beyond; and, a gate from the third segment a distance into the second segment or before. This produces an obfuscated sequence of reversible gates. Obfuscated instructions based on the obfuscated sequence of gates are sent to the public resources.
