Published in 2018 at "Bulletin of Earthquake Engineering"

DOI: 10.1007/s10518-018-0319-7

Abstract: Damage assessments after past earthquakes have frequently revealed that plan configuration irregular buildings have more severe damage due to excessive torsional responses and stress concentration than regular buildings. The plan configuration irregularities introduce major challenges… read more here.

Published in 2022 at "NPJ Schizophrenia"

DOI: 10.1038/s41537-022-00239-7

Abstract: Schizophrenia subjects often suffer from a failure to properly predict incoming inputs; most notably, some patients exhibit impaired prediction of the sensory consequences of their own actions. The mechanisms underlying this deficit remain unclear, though.… read more here.
