Ionospheric Disturbances Observed Following the Ridgecrest Earthquake of 4 July 2019 in California, USA

open access: yesRemote Sensing, 2022
Earthquakes are known to generate disturbances in the ionosphere. Such disturbances, referred to as co-seismic ionospheric disturbances, or ionoquakes, were previously reported for large earthquakes with magnitudes Mw≥ 6.6.

Ionospheric disturbances observed over Japan following the eruption of Hunga Tonga-Hunga Ha’apai on 15 January 2022

open access: yesEarth, Planets and Space, 2022
Traveling ionospheric disturbances (TIDs) were observed over Japan by using Global Navigation Satellite System (GNSS) receiver network data after the eruption of Hunga Tonga-Hunga Ha’apai in Tonga on 15 January 2022.

TID hash joins

open access: yesProceedings of the third international conference on Information and knowledge management - CIKM '94, 1994
TID hash joins are a simple and memory-efficient method for processing large join queries. They are based on standard hash join algorithms but only store TID/key pairs in the hash table instead of entire ttrples. This typically reduces memory requirements by more than art order of magnitude bringing substantial benefits.

ADDTID: An Alternative Tool for Studying Earthquake/Tsunami Signatures in the Ionosphere. Case of the 2011 Tohoku Earthquake

open access: yesRemote Sensing, 2019
In this work, we characterized the ionospheric disturbances generated during the Japan Tohoku earthquake of 11 March 2011, by means of the Atomic Decomposition Detector of Traveling Ionospheric Disturbances (ADDTID) algorithm.

Traveling ionospheric disturbances triggered by the 2009 North Korean underground nuclear explosion [PDF]

open access: yesAnnales Geophysicae, 2015
Underground nuclear explosions (UNEs) can induce acoustic-gravity waves, which disturb the ionosphere and initiate traveling ionospheric disturbances (TIDs).

A method for real-time identification and tracking of traveling ionospheric disturbances using ionosonde data: first results

open access: yesJournal of Space Weather and Space Climate, 2020
Traveling Ionospheric Disturbances (TIDs) are wave-like propagating irregularities that alter the electron density environment and play an important role spreading radio signals propagating through the ionosphere. A method combining spectral analysis and

GPS network observation of traveling ionospheric disturbances following the Chelyabinsk meteorite blast [PDF]

open access: yesAnnales Geophysicae, 2016
We use the Global Positioning System (GPS) network in northwest China and central Asia to monitor traveling ionospheric disturbances (TIDs), which were possibly excited by the large meteorite blast over Chelyabinsk, Russia, on 15 February 2013.

Temporomandibular Joint Internal Derangement Score (TIDS): novel magnetic resonance imaging assessment score and its relation to invasive treatment in patients with clinical temporomandibular joint pathology

open access: yesHeliyon, 2018
Purpose: A new magnetic resonance imaging (MRI) based scoring system for temporomandibular joint (TMJ) internal derangement was developed to predict disease severity and the likelihood of invasive treatment.
