Brain Health, EarlyView.ABSTRACT Introduction Residential environments have been linked to brain structure, particularly in children, older adults, and clinical populations. However, little is known about how different dimensions of the housing environment relate to brain white matter microstructure in healthy adults, or whether specific environmental factors show stronger ...

On Tools for Completeness of Kleene Algebra with Hypotheses [PDF]
Logical Methods in Computer ScienceIn the literature on Kleene algebra, a number of variants have been proposed which impose additional structure specified by a theory, such as Kleene algebra with tests (KAT) and the recent Kleene algebra with observations (KAO), or make specific ...

Haar Bases forL2(Rn) and Algebraic Number Theory
Journal of Number Theory, 1996 AbstractWe correct an error in the proof of Theorem 1.5 in Lagarias and Wang (J. Number Theory57, 1996, 181–197). We also give a strengthened necessary condition for the existence of a Haar basis of the specified kind for every integer matrixAthat has a given irreducible characteristic polynomialf(x) with |f(0)|=2. A.

On Graham Higman's famous PORC paper [PDF]
International Journal of Group Theory, 2012 We investigate Graham Higman's paper Enumerating p-groups, II, in whichhe formulated his famous PORC conjecture. We look at the possibilities forturning his theory into a practical algorithm for computing the number of p-class two groups of order pn for ...

On Algebras of Distributions of Binary Formulas for Theories of Unars
Известия Иркутского государственного университета: Серия "Математика", 2016 Algebras of distributions of binary isolating and semi-isolating formulas are derived structures for a given theory. These algebras reflect binary links between realizations of 1-types defined by formulas of the initial theory.

Mahler measures and Fuglede--Kadison determinants
, 2009 The Mahler measure of a function on the real d-torus is its geometric mean over the torus. It appears in number theory, ergodic theory and other fields.

Kinematic Hopf algebra for amplitudes from higher-derivative operators
Journal of High Energy PhysicsRecently it has been shown that Bern-Carrasco-Johansson (BCJ) numerators of colour-kinematic duality for tree-level scattering amplitudes in Yang-Mills theory (coupled with scalars) can be determined using a quasi-shuffle Hopf algebra.
