Prevention of venous thromboembolic complications in patients with ulcerative colitis
Терапевтический архивBackground. The incidence of venous thromboembolic complications (VTEC) in patients with inflammatory bowel diseases is approximately 3 times higher than in the general population and leads to a 2-fold increase in the risk of mortality.

How the 29 July 2025 M8.8 Kamchatka Earthquake Shook the Ionosphere Over Japan
Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.Abstract This study investigates the mid‐field (∼1,100–3,800 km) ionospheric response to the 29 July 2025 Kamchatka earthquake over Japan using multi‐instrument observations, raytracing, and numerical simulations. Total electron content (TEC) observations from GPS satellite G04 and Galileo satellite E10 show a maximum TEC perturbation of ∼0.5–0.85 TECU

Space Weather, Volume 24, Issue 7, July 2026.Abstract This study validates the four topside ionosphere model options included in the latest release of the International Reference Ionosphere (IRI‐2020) model: IRI‐2001, IRI‐2001cor, IRI‐NeQuick, and the default IRI‐COR2. To assess their ability to reproduce the topside profile while minimizing uncertainties associated with F2‐layer peak modeling ...

Risk Ranking of Microbiological Hazards in Food (2015–2019)
Food Risk Assess Europe, Volume 4, Issue 3, July 2026.Abstract Microbiological food safety risks arise from pathogens that can contaminate food at different points along the food chain. Exposure to these hazards can result in illnesses that can vary widely in severity and duration, depending on factors such as the specific pathogen involved, the amount of the pathogen ingested, and the susceptibility of ...

New formulation for the topside ionosphere and plasmasphere based on NeQuick
Journal of Space Weather and Space ClimateThe total electron content (TEC) affecting signal propagation of Global Navigation Satellite Systems (GNSS) is strongly influenced by the topside ionosphere and plasmasphere. This study introduces a new approach to representing the two regions.

Verotoxinogenic
Acta Veterinaria Scandinavica, 2003 In the autumn of 1995 the first outbreaks of enterohemorrhagic Escherichia coli O157:H7 including ca 100 human cases were reported in Sweden. From outbreaks in other countries it is known that cattle may carry these bacteria and in many cases is the ...

Comparison of GPS-derived vTEC over Cyprus with NeQuick Model [PDF]
, 2010 This paper presents a comparison of ionospheric vertical total electron content (vTEC) values evaluated from Nicosia (35.1 N, 33.4 E) ground-based GPS station in Cyprus and the corresponding predictions with the latest version of the NeQuick model during
