Artificial intelligence (AI) techniques such as deep learning (DL) for computational imaging usually require to experimentally collect a large set of labeled data train neural network. Here we demonstrate that practically usable network can be trained by using simulation data. We take ghost (CGI) an example this method. develop one-step end-to-end network, with data, reconstruct two-dimensional images directly from acquired one-dimensional bucket signals, without the need sequence...
The problem of imaging through thick scattering media is encountered in many disciplines science, ranging from mesoscopic physics to astronomy. Photons become diffusive after propagating a medium with an optical thickness over 10 times the mean free path. As result, no image but only noise-like patterns can be directly formed. We propose hybrid neural network for computational such media, demonstrating reconstruction information various targets hidden behind white polystyrene slab 3 mm or...

A conductivity is also necessary to speed up the charge transport between catalyst and electrolyte. Recently, observation of exceedingly in topological semimetal MoP, has provided a model investigate correlation electrical electrocatalytic activity for HER. Thus, MoP encapsulated Mo, P codoped carbon layer (MoP@C). This composite material exhibits...

High-purity Fe3S4 (greigite) microcrystals with octahedral shape were synthesized via a simple hydrothermal method using surfactant. The as-prepared samples have the inverse spinel structure high crystallinity. saturation magnetization (Ms) reaches 3.74 μB at 5 K and 3.51 room temperature, which is larger than all reported values thus far. Electrical transport measurements show metallic behavior resistivity 40 times lower in any previous report. potential use of greigite as an anode...

After experimentally demonstrating its feasibility, the new then applied design of ERFRA, with feed in center...
Intriguing properties are frequently reported in various topologically non-trivial materials. They include robust metallic surface states, high carrier mobility, chiral fermions, and ultralong Fermi arcs. An exciting recent finding is that these strongly related to adsorption electron transfer heterogeneous catalysis reactions, such as hydrogen evolution, oxygen reduction, enantiospecific adsorption, hydrometallation. Thus, we expect the introduction of symmetry-protected topological order...
Despite the fruitful achievements in development of hydrogen production catalysts with record-breaking performances, there is still a lack durable that could work under large current densities (>1000 mA cm-2). Here, we investigated catalytic behaviors Sr2RuO4 bulk single crystals.

These materials are stable for 56 days continuous...
Alternating magnetic fields (AMFs) are recently demonstrated as a promising strategy to promote the electrochemical catalytic reactions. However, underlying mechanisms still an open question. In this work, we systematically investigated influence of AMFs on hydrogen evolution reaction (HER) by using Fe-Co-Ni-P-B catalyst. The HER efficiency is boosted significantly AMFs, with 27% increase in current density at 20 mT. This attributed enhancement charge-transfer Lorentz interaction minor...

Wannier charge centers (OWCCs) in OAIs pinned by symmetries at some empty Wyckoff...
We demonstrate experimentally that the traditional double random phase encoding (DPRE) technique is vulnerable to cyphertext-only attack (COA). With statistical ergodic property of speckle, we show plaintext image can be recovered from cyphertext alone owing fact their energy spectral density functions are identical. Our result reveals most serious security issue with DRPE as it suggests even one-time-pad does not guarantee its security. This will open up new inside understanding current...
