Cannon–Thurston maps, subgroup distortion, and hyperbolic hydra
subgroup distortion hyperbolic hydra
2015/8/26
We prove that Cannon–Thurston maps are well–defined (that is, subgroup inclusion induces a map of the boundaries) for heavily distorted free subgroups inside the family of hyperbolic groups known as h...
Finite lattice distortion patterns in plastically deformed zircon grains
Limit deformation mode the grains high temperature and natural shear zone the Alps MaYan
2015/1/6
This study examines finite deformation patterns of zircon grains from high-temperature natural shear zones. Various zircon-bearing rocks were collected in the Western Tauern Window, eastern Alps, wher...
Realizable Rate Distortion Function and Bayesian FIltering Theory
Realizable Rate Distortion Function Bayesian FIltering Theory Information Theory
2012/4/16
The relation between rate distortion function (RDF) and Bayesian filtering theory is discussed. The relation is established by imposing a causal or realizability constraint on the reconstruction condi...
Entropy, Lyapunov exponents and the volume growth of boundary distortion under the action of dynamical systems
Lyapunov exponents the volume growth of boundary distortion the action of dynamical systems
2012/4/17
We study the connection between the Lyapunov exponents and the volume growth of boundary distortion of regions in the phase space of the dynamical system.
A viscoplasticity model with an enhanced control of the yield surface distortion
viscoplasticity yield function kinematic hardening distortional hardening rheology
2012/4/17
A new model of metal viscoplasticity, which takes combined isotropic, kinematic, and distortional hardening into account, is presented. The basic modeling assumptions are illustrated using a new two-d...
Block magnetism coupled with local distortion in the iron-based spin-ladder compound BaFe2Se3
Block magnetism local distortion iron-based spin-ladder compound BaFe2Se3
2012/2/27
Magnetism in the insulating BaFe$_2$Se$_3$ was examined through susceptibility, specific heat, resistivity and neutron diffraction measurements. After formation of a short-range magnetic correlation, ...
Distortion of wreath product in Thompson's group F
Thompson's group F restricted wreath product quasi-isometrically embedded
2011/10/20
Distortion of subgroups in finitely generated groups is a topical subject in geometric group theory.Thompson's group F has important tools of reduced tree diagrams and reduced forest diagrams. Using t...
A Unified Analysis of Transmission with Transceiver Distortion and Some Applications
Unified Analysis of Transmission Transceiver Distortion Applications
2011/1/19
A unified analysis is presented for information transmission over Gaussian channels with memoryless nonlinear transceiver distortion, which encompasses various distortion models including transmit-sid...
On equicontinuity of homeomorphisms with finite distortion in the plane
homeomorphisms finite distortion
2011/2/24
It is stated equicontinuity and normality of families F of the so–called homeomorphisms with
finite distortion on conditions that Kf (z) has finite mean oscillation, singularities of logarithmic typ...
Antiferromagnetic ordering in the absence of a structural distortion in Ba(Fe{1-x}Mn{x})2As2
Stripe Antiferromagnetic structural distortio
2010/11/22
Neutron and x-ray diffraction studies of Ba(Fe1−xMnx)2As2 for low doping concentrations (x 6 0.176)reveal that at a critical concentration, 0.102 < x < 0.118, the tetragonal-to orthorhombic tran...
Influence of tetragonal distortion on the magnetic and electronic properties of the Heusler compound Co2TiSn from first principles
Influence of tetragonal distortion magnetic and electronic properties first principles
2010/11/22
Using the full potential linearized augmented plane wave plus local orbitals method we determine ab-initio the lattice parameters of tetragonally distorted Co2TiSn in the L21 structure. The tetragonal...

We have carried out ab-initio calculation and study of structural and elec-tronic properties of AgAlM2 (M = S, Se, Te) chalcopyrite semiconductors using Density Functional Theory (DFT) based self cons...
It is shown that every homeomorphism f of finite distortion in the plane is the so-called lower Q-homeomorphism with Q(z)=K_f(z), and, on this base, it is developed the theory of the boundary behavior...

2010/11/5
We exploit a connection between uncertainty relations and low-distortion embeddings of L2 into L1, which allows us to adapt an explicit low-distortion embedding to obtain efficient entropic uncertaint...
