Six million years ago atmospheric shifts grassland mammals
2019/10/30
Six million years ago, grass-eating mammals became more diverse in South America. Shifts in tropical atmospheric circulation known as Hadley circulation led to changes in climate and vegetation, espec...
Constructing APN functions through isotopic shifts
Boolean function APN isotopic equivalence
2018/8/28
Almost perfect nonlinear (APN) functions over fields of characteristic 2 play an important role in cryptography, coding theory and, more generally, information theory as well as mathematics. Building ...
Musical literacy shifts asymmetries in the ventral visual cortex
Hemispheric specialization Lateralization Music notation
2017/8/25
The acquisition of literacy has a profound impact on the functional specialization and lateralization of the visual cortex. Due to the overall lateralization of the language network, specialization fo...
Accounting for rate-dependent category boundary shifts in speech perception
Speech rate Rate-dependent perception Rate normalization
2017/8/25
The perception of temporal contrasts in speech is known to be influenced by the speech rate in the surrounding context. This rate-dependent perception is suggested to involve general auditory processe...
