Cryoconite: an efficient accumulator of radioactive fallout in glacial environments

open access: yesThe Cryosphere, 2020
. Cryoconite is rich in natural and artificial radioactivity, but a discussion about its ability to accumulate radionuclides is lacking. A characterization of cryoconite from two Alpine glaciers is presented here.

Evidence accumulator or decision threshold - which cortical mechanism are we observing?

open access: yesFrontiers in Psychology, 2012
Most psychological models of perceptual decision making are of the accumulation-to-threshold variety. The neural basis of accumulation in parietal and prefrontal cortex is therefore a topic of great interest in neuroscience.

Communication and Language Profiles of Children Treated for Posterior Fossa Brain Tumors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cognitive and language deficits are frequently reported sequelae of posterior fossa brain tumors (PFBT). Typically, delayed onset impedes prompt assessment and early intervention. This has devastating implications for quality of life.
