Superior PM2.5 Estimation by Integrating Aerosol Fine Mode Data from the Himawari-8 Satellite in Deep and Classical Machine Learning Models

open access: yesRemote Sensing, 2021
Artificial intelligence is widely applied to estimate ground-level fine particulate matter (PM2.5) from satellite data by constructing the relationship between the aerosol optical thickness (AOT) and the surface PM2.5 concentration. However, aerosol size

Adenomatoid odontogenic tumor of the mandible: review of the literature and report of a rare case

open access: yesHead & Face Medicine, 2005
Adenomatoid odontogenic tumor (AOT) is a rare odontogenic tumor which is often misdiagnosed as odontogenic cyst. To acquire additional information about AOT, all reports regarding AOT and cited in "pubmed" since 1990 onward were reviewed.

Pharmacological pain relief and postpartum bleeding in women with moderate or severe anemia: A cohort analysis of the WOMAN‐2 trial

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Pain relief could minimize blood loss by limiting the adrenaline stress response to fear and trauma during birth. We examined the association between pharmacological pain relief and postpartum bleeding in a large cohort of women giving birth with anemia in sub‐Saharan Africa and South Asia.
