Neuromorphic Optical Tracking and Imaging of Randomly Moving Targets Through Dynamic Dense Scattering Media

Advanced Science, EarlyView.
Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...

Giant Magneto‐Optical Effects in Two‐Dimensional Flat‐Band Antiferromagnets

Advanced Science, EarlyView.
RuOCl2${\rm RuOCl}{_2}$, a two‐dimensional antiferromagnet, hosts energy bands with pronounced directional flatness. This study demonstrates that the flat‐band‐induced optical transitions yield strongly anisotropic absorption and a record‐large magneto‐optical Schafer–Hubert effect, alongside exceptional linear dichroism exceeding 50%.

Iron‐Tannic Acid Hydrogel Mediated Mild Photothermal Therapy Combined With Ferroptosis Enhances Anti‐Tumor Immunity in Colorectal Cancer

Advanced Science, EarlyView.
An injectable gelatin‐based tannic acid–iron hydrogel with mild photothermal therapy could not only induce immunogenic cell death, but also elicit ferroptosis of both tumor cells and tumor‐associated macrophages, resulting in DC maturation, T‐cell infiltration and down‐regulation of ferroptosis‐sensitive M2‐type TAMs levels.

Bifurcações no controle de um conversor boost bidirecional operando em uma microrrede CC

Proceeding Series of the Brazilian Society of Computational and Applied Mathematics, 2015
Este artigo apresenta uma analise de bifurcacoes de um conversor de eletronica potencia boost bidirecional, considerando uma estrategia de controle por modos deslizantes (SMC) para microrredes de corrente continua (cc) em modo ilhado. Esta analise tem por objetivo identificar fenomenos ligados as bifurcacoes dos equilibrios que possam levar o sistema a
