Abstract National‐scale benthic marine habitat maps underpin monitoring and conservation of vulnerable marine and coastal ecosystems. Cloud‐based satellite remote sensing can streamline these processes over spatial s...

Subspace mapping methods aim at projecting high-dimensional data into a subspace where a specific objective function is optimized. Such dimension reduction allows the removal of collinear and irrelevant variables for cre...

This study proposes a customized sidelink synchronization signal block (SSB) and corresponding reception designs tailored for 60 GHz wireless personal area network (WPAN) systems. To enable high-data-rate transmissions a...

Low-resolution images often lack fine detail and are prone to blurring, noise, and distortions, making accurate assessment challenging. This issue becomes even more challenging for applications, such as land mapping, env...

State-of-charge (SOC) estimation for LiFePO4 (LFP) batteries presents challenges due to their flat open-circuit voltage. Recent studies suggest that electrochemical impedance spectroscopy (EIS) offers a promising approac...

Dimensionality Reduction (DR) is essential for filtering noise in high-dimensional data and enabling visualization, yet traditional non-linear methods often lack parametric mappings or distort global geometry. We prop...

Abstract We present a continuous-variable (CV), quantum-key-distribution (QKD)—inspired, keyed physical-layer masking method for classical M-level pulse-amplitude-modulation (M-PAM) links. A transmitter adds a per-symb...

Driven by satellite remote sensing observations, deep learning models provide a promising solution for the rapid estimation of subsurface thermohaline structures. By learning from large-scale paired surface–subsur...

The photon-counting laser altimeter onboard the Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2) offers a new opportunity for bathymetric mapping in nearshore extremely shallow waters (0–5 m). However, its single-...

Abstract In Digital Image Processing (DIP), image enhancement using univalent functions entails mapping pixel intensity values (gray levels) using one-to-one, invertible complex functions, frequently in the frequency dom...

A method is developed for representing any communication system geometrically. Messages and the corresponding signals are points in two "function spaces," and the modulation process is a mapping of one space into the oth...

The all sky surveys done by the Palomar Observatory Schmidt, the European Southern Observatory Schmidt, and
\nthe United Kingdom Schmidt, the InfraRed Astronomical Satellite, and the Two Micron All Sky Survey have&#1...

Abstract Optical methods deployed for studying motion and deformation of objects often struggle to distinguish small displacements hidden behind observational noise. In geophysical applications, this has limited analysis...

We study numerically and experimentally the second-harmonic generation (SHG) from rectangular metagratings of V-shaped gold nanoantennas. We show that by carefully engineering the array pitch to steer the diffraction ord...

We introduce a numerical optimization method to extract the X-ray reverberation response functions from multiband light curves of active galactic nuclei. This approach does not require prior assumptions about the geometr...
