Fine-scale exogenous attention within the foveola selectively enhances contrast gain at low-to-mid spatial frequencies while increasing response gain across a broad spatial frequency range.

Computer-Controlled Sub-Aperture Polishing enables high-precision surface correction using small tools. Material removal is controlled by dwell time modulation along toolpaths, but the discontinuous ...

Holographic displays create three-dimensional (3D) images that appear to float in space by manipulating light waves, often using lasers. Spatial computing is being developed to augment reality with ...

ABSTRACT: We analyzed the efficiency of a terahertz radiation produced at different pumping conditions of a first harmonic (ω0) Gaussian beam coupled with a second harmonic (2ω0) Laguerre-Gaussian ...

Biomolecular condensates play important roles in cellular organization and function, but their internal structures remain poorly understood due to limitations in imaging techniques. This is true for ...

Abstract: A specific limitation of spatial modulation (SM) is that the number of transmit antennas must be a power of two, otherwise it will cause a fractional bits problem. To solve this problem, ...

Abstract: This paper proposes an active-intelligent reflecting surface (IRS) assisted joint spatial and reflecting modulation (A-IRS-JSRM). The proposed A-IRS-JSRM engages an active IRS with ...

First, neurophysiological evidence for the learning of invariant representations in the inferior temporal visual cortex is described. This includes object and face representations with invariance for ...

Earth observation (EO) from space is important for resource monitoring and management. The performance of optical EO sensors is determined by four resolutions: spatial, spectral, radiometric and ...
