A Coordinate Registration Method for Over-the-Horizon Radar Based on Graph Matching
Coordinate registration (CR) is the key technology for improving the target positioning accuracy of sky-wave over-the-horizon radar (OTHR). The CR parameters are derived by matching the sea–land clutter classification (SLCC) results with prior geographic

How Regulatory Costs Impede Financial Technology Gains
ABSTRACT While financial technology innovation lowers intermediation costs, regulatory frictions may prevent these gains from reaching long‐term investors and borrowers. Using variation in retail investor participation driven by state securities registration lapses in peer‐to‐peer lending, we demonstrate that regulatory frictions are associated with ...

Moisture Aggregation and the Cloud Transition Zone Shape Mesoscale Aerosol Properties
Abstract Mesoscale moisture aggregation and cloud organization in shallow convection have gained much attention regarding their role in Earth's energy budget and cloud feedbacks on climate. Because aerosol particles swell in humid air, mesoscale moisture patterns are expected to be accompanied by corresponding variations in aerosol optical depth (AOD).

Sky and ground - wave high frequency (HF) radars: challenges in modelling, simulation and application preface [PDF]
Radar systems operating at high frequency (HF) are able to exploit a variety of propagation mechanisms to achieve line-of-sight (LOS) illumination as well as over-the-horizon coverage, thereby providing many opportunities for long range, wide area multi ...

Abstract Equatorial plasma bubbles (EPBs) are major low‐latitude ionospheric irregularities that can cause scintillation and degrade Global Navigation Satellite System (GNSS) performance. Existing amplitude‐scintillation prediction methods primarily use historical GNSS observations and ionospheric parameters, but rarely incorporate the evolving spatial

This study presents a hybrid AI framework that enables autonomous magnetic microrobots to navigate complex, non‐Newtonian tumor microenvironments. By integrating physics‐informed recurrent reinforcement learning with active persistent excitation, the system successfully infers hidden fluid rheology for precise targeted navigation and structural causal ...

Study on the Detectability of the Sky-Surface Wave Hybrid Radar
Working in the HF (high-frequency) band and the transmitter and receiver locating separately, the sky-surface wave hybrid radar both has the capabilities of the OTHR (over-the-horizon radar) and the advantage of the bistatic radar. As the electromagnetic

Adaptive transient and CW RF interference mitigation in HF OTH radar: Experimental results
We introduce an adaptive technique for the joint mitigation of transients and continuous-wave radio-frequency co-channel interference (CW RFI) in high-frequency (HF) over-the-horizon radars (OTHRs).

ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full
