Replica wormholes for an evaporating 2D black hole
Journal of High Energy Physics, 2021 Quantum extremal islands reproduce the unitary Page curve of an evaporating black hole. This has been derived by including replica wormholes in the gravitational path integral, but for the transient, evaporating black holes most relevant to Hawking’s ...

Generalized Navier–Stokes Equations with Non-Homogeneous Boundary Conditions
Fractal and Fractional, 2022 We study the generalized unsteady Navier–Stokes equations with a memory integral term under non-homogeneous Dirichlet boundary conditions. Using a suitable fractional Sobolev space for the boundary data, we introduce the concept of strong solutions.

On non-linear boundary value problems and parametrisation at multiple nodes
Electronic Journal of Qualitative Theory of Differential Equations, 2016 We show how a suitable interval division and parametrisation technique can help to essentially improve the convergence conditions of the successive approximations for solutions of systems of non-linear ordinary differential equations under non-local ...

Algorithms, 2023 Integro-differential equations involving Volterra and Fredholm operators (VFIDEs) are used to model many phenomena in science and engineering. Nonlocal boundary conditions are more effective, and in some cases necessary, because they are more accurate ...

Studying a system of non-local condition hyperbolic equations
Қарағанды университетінің хабаршысы. Математика сериясыLocal boundary value problems for hyperbolic differential equations have been studied in considerable detail. However, the mathematical modeling of a number of real-world processes leads to nonlocal boundary value problems involving nonlinear hyperbolic

Mass Minimization of Dynamically Loaded Machine Foundations Using Different Subsoil Models
Engineering Transactions, 2015 The effect of variation of the shear wave velocity profile of a layered soil on a minimal mass of a rigid machine foundation under behavior constraints on vibration and normal stress contact amplitudes and side constraints is numerically studied.

Localized boundary-domain integral equation formulation for mixed type problems [PDF]
gmj, 2010 Abstract Some modifed direct localized boundary-domain integral equations (LBDIEs) systems associated with the mixed boundary value problem (BVP) for a scalar “Laplace” PDE with variable coefficient are formulated and analyzed. The main results established in the paper are the LBDIEs equivalence to the original variable-coefficient BVPs ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
