Bio‐inspired artificial retina with receptive fields for in‐sensor multiply‐and‐accumulate operations

open access: yesInfoMat, Volume 8, Issue 8, August 2026.
We developed a bio‐inspired artificial retina in which curved artificial receptive fields composed of perovskite photoconductors perform multiply‐and‐accumulate operations through in‐sensor computing. This architecture simultaneously realized the structural efficiency of human eyes (compact single‐lens imaging system) and functional advantages of ...

A multidisciplinary experimental and methodological investigation of electron and proton minibeams in the framework of the INFN MIRO project

open access: yesMedical Physics, Volume 53, Issue 8, August 2026.
Abstract Background The clinical translation of Minibeam RT (MBRT) has recently started thanks to the first human treatments recently performed. However, despite experimental evidence, the impact of the dose distribution parameters involved on the magnitude of the effect itself and the underlying radiobiological mechanisms are still only partially ...

Wavelet Transform‐Based Atomic Force Microscopy: A Computational Paradigm for Dynamic Nanoscale Imaging and Characterisation

open access: yesSmall Science, Volume 6, Issue 8, August 2026.
Wavelet transform‐based AFM enables real‐time nanoscale imaging by applying wavelet analysis to raw cantilever deflection signals. It reveals non‐linear, transient and multi‐frequency dynamics beyond conventional steady‐state methods. Integrated with adaptive filtering and digital twin modelling, it produces high‐resolution, information‐rich maps of ...

Resources of Digital FIR Filters Hardware Implementation in FPGAs for Digital Image Processing in Real Time

open access: yesAdvances in Electrical and Electronic Engineering, 2004
The main image information content, from the human visual system viewing point, is focused into whole colorimetric and spatial informations. Because every image is result of some previous processes, the goal for all standard image processing methods is ...

On the Role of Hydrogen Bond Strength and Charge Transfer in an On‐Water Diels–Alder Reaction: Semiempirical and Free Energy Calculations

open access: yesJournal of Computational Chemistry, Volume 47, Issue 20, July 30, 2026.
Matched Diels‐Alder dienophiles at a water interface reveal that on‐water catalysis depends on hydrogen‐bond quality rather than hydrogen‐bond count. Oxygen preserves charge‐transfer coupling and lowers the free‐energy barrier, whereas sulfur disrupts this coupling and promotes an asynchronous pathway.

Optical Phased Arrays on Photonic Integrated Circuit Platforms: Challenges, Opportunities, and Future Applications

open access: yesNanophotonics, Volume 15, Issue 14, 27 July 2026.
Integrated optical phased arrays are emerging as scalable engines for solid‐state beam steering and programmable wavefront control. This Review maps the field from beam‐steering principles and core building blocks to material platforms, system‐level bottlenecks, and application frontiers, highlighting how heterogeneous integration, aperiodic ...

Space‐Time‐Coding Metasurfaces Enabling Programmable Range‐Angle‐Dependent Energy Auto‐Scanning

open access: yesNanophotonics, Volume 15, Issue 14, 27 July 2026.
This paper presents a novel energy auto‐scanning system based on a space‐time‐coding metasurface. By applying progressive time‐delayed, time‐varying phase modulation, the system generates non‐uniform, temporally evolving electromagnetic field distributions across both angle and range.

Noninvasive Intelligent Brain‐Metasurface System for Real‐Time Electromagnetic Wave Manipulation

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
A noninvasive intelligent brain–computer interface (BCI) is integrated with a reconfigurable metasurface to establish a direct neural‐to electromagnetic transduction pathway for real time, multimodal wave control. By combining convolutional‐neural‐network‐based decoding of motor‐imagery electroencephalography (EEG) signals with threshold‐based ...
