analytical solutions of model equations for two phase gas mixtures: Transverse velocity perturbations
(AIP Publishing, 1984)Model equations for a dilute binary gas system are derived, using a linear BGK scheme. Complete analytical solutions for the stationary half_space problem are obtained for transverse velocity perturbations. The method of ... 
Anomalous decay of a prepared state due to nonOhmic coupling to the continuum
(American Physical Society, 201003)We study the decay of a prepared state E(0) into a continuum {E(k)} in the case of nonOhmic models. This means that the coupling is V(k),(0) proportional to E(k)E(0)(s1) with s not equal 1. We find that irrespective ... 
anomaly meltdown
(AIP Publishing, 199108)It is shown that at nonzero temperature it is possible that anomalies in representations of symmetry groups and gauge groups, present at zero temperature, disappear. Several examples are given. Thus the idea that anomalies ... 
Antibiotics ameliorate lupuslike symptoms in mice
(Nature, 20171020)Gut microbiota and the immune system interact to maintain tissue homeostasis, but whether this interaction is involved in the pathogenesis of systemic lupus erythematosus (SLE) is unclear. Here we report that oral antibiotics ... 
Antibody Responses during Hepatitis B Viral Infection
(PLOS, 201407)Hepatitis B is a DNA virus that infects liver cells and can cause both acute and chronic disease. It is believed that both viral and host factors are responsible for determining whether the infection is cleared or becomes ... 
Approximate Deconvolution Reduced Order Modeling
This paper proposes a large eddy simulation reduced order model(LESROM) framework for the numerical simulation of realistic flows. In this LESROM framework, the proper orthogonal decomposition(POD) is used to define the ... 
asymptoticbehavior of Jost functions near resonance points for WignerVonneumann type potentials
(AIP Publishing, 199101)In this work are considered radial Schrodinger operators  psi" + V(r)psi = Epsi, where V(r) = a sin br/r + W(r) with W(r) bounded, W(r) = O(r2) at infinity (a,b real). The asymptotic behavior of the Jost function and ... 
asymptotics of the scattering coefficients for a generalized Schrodinger equation
(AIP Publishing, 199908)The generalized Schrodinger equation d(2)psi/dx(2) + F(k)psi=[ikP(x) + Q(x)]psi is considered, where P and Q are integrable potentials with finite first moments and F satisfies certain conditions. The behavior of the ... 
A Bistable Switch in Virus Dynamics Can Explain the Differences in Disease Outcome Following SIV Infections in Rhesus Macaques
(Frontiers, 20180606)Experimental studies have shown that the size and infectiousstage of viral inoculum influence disease outcomes in rhesus macaques infected with simian immunodeficiency virus. The possible contribution to disease outcome ... 
Bridging Frameworks for Understanding Numerical Cognition
(LeibnizInstitute for Psychology Information (ZPID), 20180607) 
Calibrated Filtered Reduced Order Modeling
We propose a calibrated filtered reduced order model (CFROM) framework for the numerical simulation of general nonlinear PDEs that are amenable to reduced order modeling. The novel CFROM framework consists of two steps: ... 
Canonical dual approach to solving 01 quadratic programming problems
(American Institute of Mathematical Sciences, 200802)This paper presents a canonical duality theory for solving nonconvex polynomial programming problems subjected to box constraints. It is proved that under certain conditions, the constrained nonconvex problems can be ... 
capillarygravity wave drag
(AIP Publishing, 200108)Drag due to the production of capillarygravity waves is calculated for an object moving along the surface of a liquid. Both two and three dimensional objects, moving at large Froude and Weber numbers, are treated. (C) ... 
Case eigenfunction expansion for a conservative medium
(AIP Publishing, 197602)By using the resolvent integration technique introduced by Larsen and Habetler, the one‐speed, isotropic scattering,neutron transport equation is treated in the infinite and semi‐infinite media. It is seen that the results ... 
Cauchyproblem for the linearized version of the Generalized Polynomial KdV equation
(AIP Publishing, 199206)In the present paper results about the "Generalized Polynomial Kortewegde Vries equation" (GPKdV) are obtained, extending the ones by Sachs [SIAM J. Math. Anal. 14, 674 (1983)] for the Kortewegde Vries (KdV) equation. ... 
ChernSchwartzMacPherson classes for Schubert cells in flag manifolds
We obtain an algorithm computing the ChernSchwartzMacPherson (CSM) classes of Schubert cells in a generalized flag manifold G/B. In analogy to how the ordinary divided difference operators act on Schubert classes, each ... 
Cohomology of Finite Groups
(University of Essen, 1992)This is a short lecture course on the cohomology of finite groups. Topics include Künneth formula, cup products and cohomology ring, differential graded algebras, Evens norm map and the Steenrod operations.

Commutative rings with homomorphic power functions
(Hindawi, 19920101)A (commutative) ring R (with identity) is called mlinear (for an integer m≥2) if (a+b)m=am+bm for all a and b in R. The mlinear reduced rings are characterized, with special attention to the finite case. A structure ...
