A Needle in a Haystack: Landscape Survey and Archaeological Detection Experiments in Apalachee Bay

open access: yesArchaeological Prospection, Volume 32, Issue 2, Page 263-280, April/June 2025.
ABSTRACT This paper presents the results of a pilot landscape‐scale seismic survey undertaken in Apalachee Bay, Florida, across a submerged landscape that contains dozens of Pre‐Contact sites. In addition to the goals of improving the geophysical and remote sensing ground model for this submerged landscape, the survey also sought to undertake the first

L’ús dels webs per a afavorir l’accés i l’increment de públic als museus: experiències dels museus nacionals britànics

open access: yesDigithum, 2005
S'ha parlat molt en els darrers anys sobre el potencial dels webs per a incrementar l'accés als museus i obrir-los a nous públics. Però, en concret, què s'està fent en aquesta línia i amb quina efectivitat?

Benthic invertebrates in the Wadden Sea form a stable community characterized by facilitating relationships

open access: yesEcosphere, Volume 16, Issue 4, April 2025.
Abstract Entire tidal food webs rely on the presence and productivity of benthic invertebrates. These invertebrates recycle nutrients, decompose organic matter, and function as food for myriad species at higher trophic levels. The interactions between benthic invertebrate species also play an important role in shaping the ecological functioning of ...

High‐precision simulation technology for enhanced Loran signal simulators based on Lagrange farrow structure filter

open access: yesIET Radar, Sonar & Navigation, 2023
In this study, a real‐time high accuracy signal simulation technique for an enhanced Loran (eLoran) signal simulator is proposed, which can be used to verify the performance of the eLoran receiver.

Analysis and Prediction Method for the Ground Wave Propagation Delay Characteristics of Long‐Wave Time Signals

open access: yesIET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.
Carry out unified analysis and modelling for the long‐wave ground wave propagation delay affected by multiple factors, so as to improve the accuracy of its delay prediction and the efficiency of engineering implementation. ABSTRACT At present, researchers often focus on various aspects such as the meteorological conditions along the long‐wave ...

E-LORAN

open access: yes, 2023
How electronic navigation developed through radio and radar navigation, a new way of determining position was found in hyperbolic navigation. Hyperbolic navigation uses curves called hyperbolas that connect places of equal distance from the focal points to find the position of a ship at their intersection.

Latitudinal Clines in an Ectothermic Vertebrate: Patterns in Body Size, Growth Rate, and Reproductive Effort Suggest Countergradient Responses in the Prairie Lizard

open access: yesEcology 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 ...
