Some new nonlinear secondorder boundary value problems on an arbitrary domain
(20181201)In this paper, we develop the existence theory for nonlinear secondorder ordinary differential equations equipped with new kinds of nonlocal nonseparated type integral multipoint boundary conditions on an arbitrary ... 
Lyapunov Functions to Caputo Fractional Neural Networks with TimeVarying Delays
(20180509)One of the main properties of solutions of nonlinear Caputo fractional neural networks is stability and often the direct Lyapunov method is used to study stability properties (usually these Lyapunov functions do not depend ... 
An existence principle for nonlocal difference boundary value problems with φlaplacian and its application to singular problems
(2008)The paper presents an existence principle for solving a large class of nonlocal regular discrete boundary value problems with the ψLaplacian. Applications of the existence principle to singular discrete problems are given. 
Superhyperfine interactions in the electronspinresonance spectrum of substitutional gd3+ impurity in caf2 single crystals under applied stress
(19670703)In this communication we report a superhyperfine structure in the esr spectrum of 0.001 at. ~0 Gd' in a single crystal of CaF, under applied stress. The stress was applied at the polished (111)face of the CaF, crystal ... 
Measurement of highpT single electrons from heavyflavor decays in p+p collisions at s=200GeV
(20061221)The momentum distribution of electrons from decays of heavy flavor (charm and bottom) for midrapidity y<0.35 in p+p collisions at s=200GeV has been measured by the PHENIX experiment at the BNL Relativistic Heavy Ion ... 
Scaling properties of azimuthal anisotropy in Au+Au and Cu+Cu collisions at sNN=200GeV
(20070416)Differential measurements of elliptic flow (v2) for Au+Au and Cu+Cu collisions at sNN=200GeV are used to test and validate predictions from perfect fluid hydrodynamics for scaling of v2 with eccentricity, system size, and ... 
System size and energy dependence of jetinduced hadron pair correlation shapes in Cu+Cu and Au+Au collisions at sNN=200 and 62.4 GeV
(20070604)We present azimuthal angle correlations of intermediate transverse momentum (14GeV/c) hadrons from dijets in Cu+Cu and Au+Au collisions at sNN=62.4 and 200 GeV. The awayside dijet induced azimuthal correlation is broadened, ... 
ON FINITE ELEMENT METHODS FOR THE EULERPOISSONDARBOUX EQUATION.
(198412)We deal primarily with the derivation of various convergence estimates for some semidiscrete and fully discrete procedures which might be used in the approximation of exact solutions of initialboundary value problems with ... 
A multigrid method for variable coefficient Maxwell's equations
(2006)This paper presents a multigrid method for solving variable coefficient Maxwell's equations. The novelty in this method is the use of interpolation operators that do not produce multilevel commutativity complexes that lead ... 
Singular positone and semipositone boundary value problems of second order delay differential equations
(200506)In this paper we present some new existence results for singular positone and semipositone boundary value problems of second order delay differential equations. Throughout our nonlinearity may be singular in its dependent ... 
Differential inclusions on proximate retracts of separable Hilbert spaces
(2006)New existence results are presented which guarantee the existence of viable solutions to differential inclusions in separable Hilbert spaces. Our results rely on the existence of maximal solutions for an appropriate ... 
On a class of twopoint boundary value problems with singular boundary conditions
(2006)A new existence theory for a class of second order twopoint boundary value problems with nonlinear boundary conditions which can blow up in finite intervals is established. The proofs are based on the dual variational ...
