The Mother's Day Geomagnetic Storm on 10 May 2024: Aurora Observations and Low Latitude Space Weather Effects in Mexico

open access: yesSpace Weather, Volume 22, Issue 11, November 2024.
Abstract On 10 May 2024, a severe geomagnetic storm coinciding with Mother's Day in Mexico lasted over 40 hr and produced polar auroras observable at low latitudes. This storm, the most intense since 2003, resulted from a series of solar flares and coronal mass ejections from active region 3664.

Disease recurrence during supportive therapy following peri‐implantitis treatment: A retrospective study

open access: yesJournal of Periodontal Research, Volume 59, Issue 5, Page 918-928, October 2024.
Abstract Aim Supportive therapy is key to prevent disease recurrence after peri‐implantitis treatment. The primary objective was to quantify disease recurrence during supportive peri‐implant therapy (SPIT) after peri‐implantitis treatment. A secondary objective was to assess the success/failure of cumulative interceptive supportive therapy (CIST) after
