Observation of Terrestrial Gamma-Ray Flashes at Mid Latitude
2021
We present a sample of Terrestrial Gamma-ray Flashes (TGFs) observed at mid latitudes by the Atmosphere Space Interaction Monitor (ASIM). The events were detected between June 2018 and August 2020 in the latitude bands between 35° and 51° in both hemispheres, which we hereafter refer to as “mid latitudes.” The sample includes the first observations above urn:x-wiley:2169897X:media:jgrd57293:jgrd57293-math-0001 and consists of 14 events clustered in four geographical regions: north-west Atlantic and eastern USA; Mediterranean Sea; the ocean around South Africa; and north-eastern China and Siberia. We examine the characteristics of each event, both standalone and in the context of the global …
REsect: Blinded assessment of amenability to potentially curative treatment of previously unresectable colorectal cancer liver metastases (CRC LM) af…
2017
3532 Background: Secondary resection and radiofrequency ablation (RFA) of primarily unresectable LM from CRC can prolong survival and cure some patients (pts). Effective downsizing treatments are needed but their impact on secondary amenability to surgery/RFA is difficult to evaluate objectively. The added value of SIRT is not well established. Methods: Baseline (BL) and follow-up (FU) imaging at best response for CRC pts treated with FOLFOX chemotherapy±bevacizumab (bev) (CT) vs. CT+SIRT in the phase III SIRFLOX RCT were reviewed by 3−5 expert HPB surgeons (from a panel of 15) for resectability of LM. Reviewers were blinded to each other and to all clinical information incl. time of imagi…
Analyse et détection des électrogrammes complexes fractionnés en vue de soigner la fibrillation auriculaire à l'aide de techniques d'ablation par rad…
2013
This manuscript presents research on the analysis and the detection of Complex Fractionated Atrial Electrograms (CFAE). In the first part, following a presentation over Atrial Fibrillation (AF) mechanisms and bioelectrical signals, the most commonly used tools for analyzing CFAE are presented. Linear tools are initially applied to signals from AF ablation procedures, then nonlinear tools are shown and integrated intoa CFAE detection algorithm. This one is based on the quantification of electrogram recurrence properties. In the second part, the cell and cardiac muscle tissue are described and simulated using mathematical models. Models such as FitzHugh Nagumo, Aliev Panfilov and Courtemanche…

The Influence of All-Night Exposure to Pulsed Radiofrequency Electromagnetic Fields on Human Sleep. Der Einfluss kontinuierlicher nachtlicher Exposit…
2005
Question of the study The widespread use of mobile telephones has led to public discussion about the putative health hazards as well as scientific interest in the interactions of pulsed, high-frequency electromagnetic fields with physiological systems. This article presents a survey of three consecutive studies carried out by a research group at the University of Mainz.
Koblācija un radiofrekvences ķirurģija otolaringoloģijā. Literatūras apskats un salīdzinoši eksperimenti in vitro
2016
Radiofrekvences un radiofrekvences koblācijas metodes aizvien vairāk tiek pielietotas kā rīkles, tā deguna gliemežnīcu ķirurģijā, tomēr dati par šo procedūru laikā sasniegtajām temperatūrām audos ir skopi. Eksperimentālā pētījuma pirmajā daļā in vitro tika iegūti dati par sasniegtajām temperatūrām koblācijas laikā, kā arī veikta paraugu, ņemtu instrumenta pieskaršanās zonā, histoloģiskā analīze. Cūkas muskuļaudos tika sasniegta 370°C, kamēr submandibulārā dziedzera audos – 320°C temperatūra. Eksperimentālā pētījuma otrajā daļā cūkas deguna gliemežnīcās koblācija tika salīdzināta ar divām citām bipolārām radiofrekvences metodēm, tika iegūti dati par sasniegtajām temperatūrām šo metožu pielie…
