Abstract Metallic mesh is a significant candidate of transparent conductive electrodes (TCEs) to substitute the current state‐of‐the‐art material indium tin oxide for optoelectronic devices. However, there remains challenge fabricate stable and good‐visibility metallic with low‐cost copper (Cu) material. A Cu electrode (on glass) high absolute transmittance ≈82% combined an adjustable low electrical resistance ≈0.2 Ω sq −1 total light reflectance 8.7% demonstrated here. The TCE shows...

The axial resolution of ultrasonic imaging is confined by the temporal width acoustic pulse generated transducer, which has a limited bandwidth. Deconvolution can eliminate this effect and, therefore, improve resolution. However, most methods perform deconvolution scan line line, and therefore information embedded within neighbor lines unexplored, especially for those materials with layered structures such as blood vessels. In paper, joint sparse representation model proposed to increase...

The use of sagittally bent asymmetric Laue crystals in horizontally focusing monochromators for high-energy synchrotron X-rays necessitates simulation the X-ray reflectivity by such crystals. Based on theory lattice distortion diffraction plane crystals, a lamellar model was developed to predict their rocking curves. experimentally verified rocking-curve measurements from various reflections silicon four representative orientations, radii, using 67 keV energy.
The effects of proton beams irradiating materials considered for targets in high-power accelerator experiments have been studied using the Brookhaven National Laboratory's (BNL) 200 MeV linac. A wide array and alloys covering a range atomic number (Z) are being scoped by community prompting BNL studies to focus on representing each distinct range, i.e. low-Z, mid-Z high-Z. low includes such as beryllium graphite, midrange Ti-6Al-4V, gum metal super-Invar finally high-Z pure tungsten...

The broad applications of manipulation electromagnetic waves (EMWs) in imaging, detection, communication, and electronic countermeasures have drawn extensive attention to the metasurface. In these applications, maintaining transparency visible light is challenging, especially when high transmittance infrared band also required, not mention substrate a nondevelopable surface. Although ITO-based metasurfaces can transmit light, ITO cannot has poor mechanical properties, coupled with...
Saliency detection has been a hot topic in computer vision. Among existing approaches, representative one is to use the convex hull prior find salient object image; and there are many variants that based on prior. Most of these works used single center construct map, while few attention made multiple centers. In this paper, we propose multi-center solution for saliency detection. Particularly, our also integrates two non-trivial optimizations: obtaining an enhanced global color distinction...
Deconvolution can improve the resolution of ultrasound system since effect point spread function be removed. Traditional methods carry out deconvolution line by line, so neighborhood information are unused. A joint sparse model is proposed in this work to discover layered structure images. The joints axial with a lateral constraint. was tested on simulation and real data, results support enhanced performance terms resolution.
Real-time dynamic monitoring of cavitation is essential for the safety and efficiency high intensity focused ultrasound (HIFU) therapy. Unlike pulse-echo imaging, which can only be use while HIFU turned off, passive acoustic mapping (PAM) enable during exposure. But conventional used PAM has low resolution interference artifacts. For this, a unique algorithm that combines frequency-sum beamforming with robust Capon beamformer (FS-RCB-PAM) was proposed in this study.
