An Unconditionally Stable Parallel Difference Scheme for Telegraph Equation [PDF]

open access: yesMathematical Problems in Engineering, 2009
We use an unconditionally stable parallel difference scheme to solve telegraph equation. This method is based on domain decomposition concept and using asymmetric Saul′yev schemes for internal nodes of each sub‐domain and alternating group implicit method for sub‐domain′s interfacial nodes.

Unconditionally Stable Difference Scheme for the Numerical Solution of Nonlinear Rosenau-KdV Equation [PDF]

open access: yesMathematics Interdisciplinary Research, 2016
In this paper we investigate a nonlinear evolution model described by the Rosenau-KdV equation. We propose a three-level average implicit finite difference scheme for its numerical solutions and prove that this scheme is stable and convergent in the ...

On the stable discretization of strongly anisotropic phase field models with applications to crystal growth [PDF]

open access: yes, 2012
We introduce unconditionally stable finite element approximations for anisotropic Allen--Cahn and Cahn--Hilliard equations. These equations frequently feature in phase field models that appear in materials science.

High-order generalized-alpha method

open access: yesApplications in Engineering Science, 2020
The generalized-α method encompasses a wide range of time integrators. The method possesses high-frequency dissipation while minimizing unwanted low-frequency dissipation. Additionally, the numerical dissipation can be controlled by the user by setting a

Alternating-direction implicit finite difference methods for a new two-dimensional two-sided space-fractional diffusion equation

open access: yesAdvances in Difference Equations, 2018
According to the principle of conservation of mass and the fractional Fick’s law, a new two-sided space-fractional diffusion equation was obtained. In this paper, we present two accurate and efficient numerical methods to solve this equation.

On the Lower Bound to the Input and Output Mismatch of Conditionally Stable Linear Two-Ports

open access: yesIEEE Journal of Microwaves, 2023
In the design of amplifier stages based on unconditionally stable linear active two-ports, the amplifier gain can be maximized through simultaneous conjugate matching with passive loads at the input and output ports.

Health‐Related Quality of Life and Symptom Severity Among Patients With PIK3CA‐Related Overgrowth Spectrum: A Mixed‐Methods Study to Understand Real‐World Experience With Alpelisib Treatment

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.
