Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract Many intraplate volcanic chains are explained as hotspot trails formed by plate motion over mantle plumes, yet some deviate from this model. The Rodrigues Ridge, a volcanic lineament extending eastward from the Réunion hotspot track toward the Central Indian Ridge (CIR), is one such case.

Introduction to Noise Radar and Its Waveforms
Sensors, 2020 In the system-level design for both conventional radars and noise radars, a fundamental element is the use of waveforms suited to the particular application. In the military arena, low probability of intercept (LPI) and of exploitation (LPE) by the enemy

A method to estimate trends in distributions of 1 min rain rates from numerical weather prediction data [PDF]
, 2015 It is known that the rain rate exceeded 0.01% of the time in the UK has experienced an increasing trend over the last 20 years. It is very likely that rain fade and outage experience a similar trend.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.Abstract We present a robust method for estimating the auroral Joule heating in the northern hemisphere by combining SuperMAG, SuperDARN and AMPERE data products. This method is applied to 292 storms during 2010–2023. Temporal evolution and spatial distributions of the storm‐time Joule heating are studied using a superposed epoch analysis, with the ...

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.Abstract Earthquakes are a primary trigger for landslides, often leading to catastrophic consequences. While numerous studies have explored the spatial distribution of earthquake‐triggered landslides, understanding the interaction between seismic waves and topography remains a critical challenge.

Automatic Modulation Classification of LFM and Polyphase-coded Radar Signals [PDF]
Radioengineering, 2017 There are several techniques for detecting and classifying low probability of intercept radar signals such as Wigner distribution, Choi-Williams distribution and time-frequency rate distribution, but these distributions require high SNR. To overcome this

Evolution of Netted Radar Systems
IEEE Access, 2020 The netted radar systems are known for being able to provide higher target detection probabilities, more accurate measurements, and better multi-target tracking performance than the monostatic/bistatic radar systems by exploiting information fusion ...

Wind-induced drift of objects at sea: the leeway field method [PDF]
, 2011 A method for conducting leeway field experiments to establish the drift properties of small objects (0.1-25 m) is described. The objective is to define a standardized and unambiguous procedure for condensing the drift properties down to a set of ...
