Path planning is a global optimization problem aims to program the optimal flight path for Unmanned Aerial Vehicle (UAV) that has short length and suffers from low threat. In this paper, we present Mixed-Strategy based Gravitational Search Algorithm (MSGSA) planning. MSGSA, an adaptive adjustment strategy gravitational constant attenuation factor alpha ( <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math...
Significantly enhanced electric field in plasmonic hot spots can dramatically increase the linear and nonlinear absorption of light, leading to a high-temperature electron gas which radiates, through mainly intraband transition, broadband luminescence quite similar blackbody radiation. Here, we demonstrate that such hot-electron (HEIL) also be achieved by exploiting significantly at magnetic dipole resonances gallium arsenide (GaAs) nanospheres (NSs). We show monocrystalline GaAs NSs with...

Abstract Gallium (Ga) is not only a metal possessing surface plasmon resonance in the ultraviolet region but also phase‐change material with very low melting point. Spherical Ga nanoparticles composed of liquid cores and solid 2 O 3 shells, which exhibit plasmonic resonances spanning to near‐infrared spectral region, are fabricated by using femtosecond laser ablation. Under excitation light, second harmonic generation observed nanospheres placed on glass substrate. In sharp contrast, white...

Brain decoding, which aims at reconstructing visual stimuli from brain signals, primarily utilizing functional magnetic resonance imaging (fMRI), has recently made positive progress. However, it is impeded by significant challenges such as the difficulty of acquiring fMRI-image pairs and variability individuals, etc. Most methods have to adopt per-subject-per-model paradigm, greatly limiting their applications. To alleviate this problem, we introduce a new meaningful task, few-shot while...
