Abstract Neuromorphic systems aim to implement large‐scale artificial neural network on hardware ultimately realize human‐level intelligence. The recent development of nonsilicon nanodevices has opened the huge potential full memristive networks (FMNN), consisting neurons and synapses, for neuromorphic applications. Unlike widely reported devices less progress. Sophisticated dynamics is major obstacle behind lagging. Here a rich dynamics‐driven neuron demonstrated, which successfully...
Conventional magnetic resonance imaging (MRI) scanners are bulky and heavy. It limits their applications at places, for example, in an ambulance or a combat field hospital. The disadvantages of conventional MRI system have led to increasing interests the development portable one. One challenges scanner is build homogenous static within volume size human parts, head, imaging. In this paper, we presented design modified permanent magnet array scanner. measurement method included.
The shielding of electromagnetic noise is critical in obtaining magnetic resonance imaging measurements the ultra-low field regime where intrinsic signal-to-noise ratio very small. traditional approach using an enclosure for expensive and hinders system portability. We describe here use a CNN-based software gradiometer to suppress effect ambient background sources that inductively couple into signal detection coils. involves three monitoring coils placed at distance from detector. were used...
We describe with a theoretical and numerical analysis the use of small permanent magnets moving along prescribed helical paths for 3D spatial encoding imaging without sample adjustment in ultra-low field magnetic resonance (ULF-MRI). With our developed method optimal magnet path orientation given number instrument architecture can be determined.

Analysis comparison presented.
Abstract Dynamically adjustable permanent magnet arrays have been proposed to generate switchable magnetic fields for pre-polarisation in Ultra-Low Field resonance imaging. However, the optimal switching dynamics of field as well energy requirements, mechanical forces and stresses during not evaluated. We analysed these requirements numerically estimated signal strength image quality two practical modes an instrument suitable scanning human head. Von Mises stress analysis showed that...

Abstract Inverse problems are some of the most important mathematical in science and mathematics because their solution yields information about parameters that not directly observable. Artificial neural networks have long been used as a modelling method successfully to solve inverse for application including denoising medical image reconstruction. Many result from integral processes can be modelled using linear formulation. These efficiently solved via simple which easily trained with...
Nowadays, the main deficiency in boosting commercialization of sodium ion battery is relatively low energy density. Herein, we propose a new way to significantly improve density by constructing negative/positive (N/P) ratio sodium-based batteries enabled reversible Na metal electrodeposition on sodiophilic zinc-metal-decorated hard carbons (Zn-HC) anode. Zn-HC used as typical insertion anode, and simultaneously substrate for plating, leading formation composite NaxC-Na anode with hybrid...
