High-Resolution Single-Pixel Imaging of Spatially Sparse Objects: Real-Time Imaging in the Near-Infrared and Visible Wavelength Ranges Enhanced with Iterative Processing or Deep Learning.

We demonstrate high-resolution single-pixel imaging (SPI) in the visible and near-infrared wavelength ranges using an SPI framework that incorporates a novel, dedicated sampling scheme and a reconstruction algorithm optimized for the rapid imaging of highly sparse scenes at the native digital micromirror device (DMD) resolution of 1024 × 768. The reconstruction algorithm consists of two stages. In the first stage, the vector of SPI measurements is multiplied by the generalized inverse of the measurement matrix.

Enhanced Visible Light Controlled Glucose Photo-Reforming Using a Composite WO/Ag/TiO Photoanode: Effect of Incorporated Plasmonic Ag Nanoparticles.

WO/Ag/TiO composite photoelectrodes were formed via the high-temperature calcination of a WO film, followed by the sputtering of a very thin silver film and deposition of an overlayer of commercial TiO nanoparticles. These synthetic photoanodes were characterized in view of the oxidation of a model organic compound glucose combined with the generation of hydrogen at a platinum cathode. During prolonged photoelectrolysis under simulated solar light, these photoanodes demonstrated high and stable photocurrents of ca.

Space-confined mediation of electron transfer for efficient biomolecular solar conversion.

Solar-converting nanosystems using self-renewing biomaterial resources carry great potential for developing sustainable technologies to ameliorate climate change and minimize reliance on fossil fuels. By mimicking natural photosynthesis, diverse proof-of-concept biosolar systems have been used to produce green electricity, fuels and chemicals. Efforts so far have focused on optimizing light harvesting, biocatalyst loading and electron transfer (ET), however, the long-term performance of best-performing systems remains a major challenge due to the intensive use of diffusive, toxic mediators.

Regional gray matter volumes are not predictive of axial symptom response to subthalamic deep brain stimulation in Parkinsonian patients.

Introduction: In Parkinson's disease (PD), axial symptom response to deep brain stimulation of the subthalamic nucleus (STN-DBS) is heterogeneous. This single-center, retrospective study aimed to assess imaging biomarkers of routine magnetic resonance imaging (MRI) to predict axial symptom response to STN-DBS, specifically by using an index of volumes of mesencephalon, pons, middle, and superior peduncle ("MR PIGD index").

Methods: We investigated 94 PD patients pre- and three to six months postoperatively by using MDS-UPDRS III, Berg Balance Scale, Freezing of Gait Questionnaire (FOG-Q) and Ziegler Course, which were related to regional brain volumetry information using regression analysis and partial least squares correlation analysis.
