ELoran signal message recognition algorithm based on GTCN‐transformer
IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.This paper introduces a novel GTCN‐Transformer network designed for the specific task of recognising message in eLoran pulse group signal. The network is constructed by enhancing the architecture of Temporal Convolutional Networks (TCN) and integrating the Transformer mechanism.

Ecology and Evolution, Volume 14, Issue 12, December 2024.The better we understand coadaptations among physiology, morphology, and life history, the more accurate our predictions will be of organismal response to changing thermal environments. We found a positive covariation of phenotypes across the thermal gradient exemplifying the enigma of “master of all traits.” Overall, compensatory responses to cooler ...

IET Microwaves, Antennas &Propagation, Volume 18, Issue 12, Page 1148-1155, December 2024.A general numerical solution of the IE is presented to predict long‐range low‐frequency groundwave propagation over irregular terrain. The great advantage of the resulting algorithm is that it can freely use non‐uniform grid sizes in the computation area without loss of accuracy.

The path to Panarctic: The emergence of an extractive frontier in Arctic Canada, 1948–1958
Canadian Geographer / Le géographe canadien, Volume 68, Issue 4, Page 513-528, Winter / hiver 2024.Abstract From the late 1940s to the late 1950s, the Geological Survey of Canada (GSC) turned vigorously to the Arctic archipelago, expanding and confirming the colonial premise that the islands of the High Arctic were an extractive frontier for oil and gas.

Weather, Volume 79, Issue 10, Page 331-337, October 2024.Abstract A drone was used to obtain thermal profiles to estimate atmospheric turbulence for the purposes of astronomical observation. The first 150 metres above ground level were studied in two areas in the south‐east of the Iberian Peninsula. The preliminary results are promising regarding the use of drones as a suitable means of transport for ...

Pseudorange reconstruction for high‐dynamic eLoran signal simulators using B‐spline interpolation
IET Radar, Sonar &Navigation, Volume 18, Issue 6, Page 931-938, June 2024.(1) A pseudorange reconstruction algorithm for High‐Dynamic signal Simulator. Highly dynamic simulators require reconstructed data and must simulate signal carrier motion in different environments. The authors propose a method of reconstruction by spline interpolation, an algorithm that balances the accuracy and feasibility of interpolation.

Bathymetric LiDAR and Semi‐Automated Feature Extraction Assist Underwater Archaeological Surveys
Archaeological Prospection, Volume 31, Issue 2, Page 171-186, April/June 2024.ABSTRACT Critical data concerning key developments in global human history now lie submerged on continental shelves where investigations confront significant challenges. Whereas underwater excavations and surveys are expensive and weather dependent and require specialized training and equipment, remote sensing methods can improve chances for success ...

Ecology and Evolution, Volume 14, Issue 4, April 2024.South Georgia and the South Sandwich Islands (SGSSI) currently has only one documented established non‐native species. However, the combination of a rapidly changing climate and an increase in tourism activities make these previously isolated islands now at risk, and in need of evidence‐based knowledge of key locations and vectors for assessing ...

The Role of Isolation in Predicting New Principals’ Burnout
International Journal of Education Policy and Leadership, 2010 Professional isolation has hampered the quality of the work experience for employees in and outside public education for decades. This study explores the role that perceived isolation plays in predicting the quality of the work experience among new ...
