Altered visual cortex excitatory/inhibitory ratio following transient congenital visual deprivation in humans [PDF]
eLifeNon-human animal models have indicated that the ratio of excitation to inhibition (E/I) in neural circuits is experience dependent, and changes across development. Here, we assessed 3T Magnetic Resonance Spectroscopy (MRS) and electroencephalography (EEG)

AIMS MathematicsThis paper addresses the problem of ensuring finite-time synchronization for fractional-order heterogeneous dynamical networks via aperiodic intermittent control, where uncertain impulsive disturbances are introduced at the instants triggered by the ...

Aperiodic Order and Quasicrystals: Spectral Properties [PDF]
Annales Henri Poincaré, 2003 Quasicrystals and other systems with aperiodic order are studied with respect to the nature of the spectrum of the associated Hamiltonians, using the framework of Delone to describe the aperiodic order. In the first part the paper is concerned with dicrete models. Delone sets with a topology and Delone dynamical systems are defined.

Aperiodic order and pure point diffraction [PDF]
Philosophical Magazine, 2008 We give a leisurely introduction into mathematical diffraction theory with a focus on pure point diffraction. In particular, we discuss various characterisations of pure point diffraction and common models arising from cut and project schemes. We finish with a list of open problems.

Fixed-Parameter Extrapolation and Aperiodic Order [PDF]
ACM SIGACT News, 2018 For a number of years we have been investigating the geometric and algebraic properties of a family of discrete sets of points in Euclidean space generated by a simple binary operation: pairwise affine combination by a xed parameter, which we call xed-parameter extrapolation.

Highly symmetric aperiodic structures -INVITED [PDF]
EPJ Web of Conferences, 2021 The symmetries of periodic structures are severely constrained by the crystallographic restriction. In particular, in two and three spatial dimensions, only rotational axes of order 1, 2, 3, 4 or 6 are possible.
