Critical properties of a superdiffusive epidemic process

Physical Review E, 2013
We introduce a superdiffusive one-dimensional epidemic process model on which infection spreads through a contact process. Healthy (A) and infected (B) individuals can jump with distinct probabilities D(A) and D(B) over a distance ℓ distributed according to a power-law probability P(ℓ)[proportionality]1/ℓ(μ).

A critical evaluation of methods for the prediction of critical properties of hydrocarbons

AIChE Journal, 1973
AbstractA critical evaluation and modification of the available methods for the estimation of critical properties of pure hydrocarbons was undertaken to determine the most accurate method which has general applicability with minimum input data. As a result of the study, the method of Nokay as modified by the authors is recommended for the estimation of

A critical review of correlations for the critical properties of defined mixtures

AIChE Journal, 1973
AbstractAn extensive critical evaluation of available correlations for predicting critical properties of binary defined hydrocarbon as well as some multicomponent hydrocarbon and hydrocarbon‐nonhydrocarbon mixtures is presented using all available literature data.

Methods and Tools for the Verification of Critical Properties

1992
This paper discusses methods for the formal treatment of critical systems. The discussion is based on experience at ICL in the application of formal methods to the development of highly assured secure systems. Problems arising in the use of the standard paradigm for specification and refinement in Z are identified and discussed.

CRITICAL PROPERTIES OF A MAGNETIZED BOSE GAS

International Journal of Modern Physics B, 1999
The critical behaviour of a dilute spin-S Bose gas in a magnetic field is investigated with the help of the renormalization group method. A complete set of critical exponents is given both at constant pressure and constant density. The magnetic properties are also discussed.

Medicinal properties of Echinacea: A critical review

Phytomedicine, 2003
Preparations from Echinacea purpurea are among the most widely used herbal medicines. Most uses of E. purpurea are based on the reported immunological properties. A series of experiments have demonstrated that E. purpurea extracts do indeed demonstrate significant immunomodulatory activities.

Critical properties of uranium selenide

Journal of Magnetism and Magnetic Materials, 1993
Abstract Bulk magnetization measurements and elastic neutron scattering have been used to determine the critical exponents β, γ and δ for single-crystal USe. The magnetization behavior in the ferromagnetic region is significantly influenced by anisotropy.

Critical Properties of One Dimensional Mappings

1980
Bifurcation theory deals with the asymptotic (long time) behaviour of systems of differential equations (continuous time) or dynamical systems (discrete time). Generally these evolution laws are non-linear and involve a few adjustable parameters (for instance temperature or boundary conditions in hydrodynamics) (1,2).
