An occult laryngeal foreign body in a 2-year-old child: A case report
Journal of Pediatric Surgery Case Reports, 2021 Laryngeal impaction of a foreign body is a rare condition. Most of the foreign bodies aspirated pass through in and lodge lower in the airways.Diagnosis of a laryngeal foreign body can be challenging, especially if it's small, radiolucent and when there ...

Psychophysical profiles in super-recognizers
Scientific Reports, 2021 Facial identity matching ability varies widely, ranging from prosopagnosic individuals (who exhibit profound impairments in face cognition/processing) to so-called super-recognizers (SRs), possessing exceptional capacities.

MagFace: A Universal Representation for Face Recognition and Quality Assessment [PDF]
Computer Vision and Pattern Recognition, 2021 The performance of face recognition system degrades when the variability of the acquired faces increases. Prior work alleviates this issue by either monitoring the face quality in pre-processing or predicting the data uncertainty along with the face ...

Blessing or curse: Impacts of the Brazilian Pre-Salt oil exploration
EconomiA, 2014 The discoveries of oil and gas in the so-called “Pre-Salt layer” have triggered a lot of discussions about their economic effect. In this paper we discuss in detail a less discussed dimension: the impact of Pre-Salt layer in the structure of the ...
