On the Subadditivity of the Entropy on the Sphere
(SpringerThe Journal of Geometric Analysis, 2015-11-17)
We present a refinement of a known entropic inequality on the sphere, finding suitable conditions under which the uniform probability measure on the sphere behaves asymptomatically like the Gaussian measure on Rᴺ with ...
Uniform Stability of Twisted Constant Scalar Curvature Kähler Metrics
(Oxford University PressInternational Mathematics Research Notices, 2015-10-14)
We introduce a norm on the space of test configurations, called the minimum norm. We conjecture that uniform K-stability is equivalent to the existence of a constant scalar curvature Kähler metric. This uniformity is ...
Delay-independent asymptotic stability in monotone systems
(IEEEAmerican Control Conference (ACC), 2015-07-03)
Monotone systems comprise an important class of dynamical systems that are of interest both for their wide applicability and because of their interesting mathematical properties. It is known that under the property of ...
Quantitative differences in developmental profiles of spontaneous activity in cortical and hippocampal cultures
(SpringerNeural Development, 2015-01-28)
Background: Neural circuits can spontaneously generate complex spatiotemporal firing patterns during
development. This spontaneous activity is thought to help guide development of the nervous system. In this study,
we had ...
A Numerical Technique for Linear Elliptic PDEs in Polygonal Domains
(Royal Society PublishingProceedings of the Royal Society A, 2015-02-11)
Integral representations for the solution of linear elliptic partial differential equations (PDEs) can be obtained using Green's theorem. However, these representations involve both the Dirichlet and the Neumann values on ...
Vortex rings impinging on permeable boundaries
(Physics of Fluids, 2015-01-17)
Experiments with vortex rings impinging permeable and solid boundaries are presented in order to investigate the influence of permeability. Utilizing Particle Image Velocimetry, we compared the behaviour of a vortex ring ...
Resonances in coupled πK, ηK scattering from lattice QCD
(APSPhysical Review D, 2015-03-10)
Coupled-channel πK and ηK scattering amplitudes are determined by studying the finite-volume energy spectra obtained from dynamical lattice QCD calculations. Using a large basis of interpolating operators, including both ...
Minimal Massive 3D Gravity Unitarity Redux
(IOPClassical and Quantum Gravity, 2015-02-26)
A geometrical analysis of the bulk and anti-de Sitter boundary unitarity conditions
of 3D “Minimal Massive Gravity” (MMG) (which evades the “bulk/boundary clash” of
Topologically Massive Gravity) is used to extend and ...
Uniqueness of the Kerr-de Sitter spacetime as an algebraically special solution in five dimensions
(SpringerCommunications in Mathematical Physics, 2015-08-20)
We determine the most general solution of the five-dimensional vacuum Einstein equation, allowing for a cosmological constant, with (i) a Weyl tensor that is type II or more special in the classification of Coley et al., ...
