Improved General Mapping Deformation Method for Nonlinear Partial Differential Equations in Mathematical Physics

Journal of Applied Mathematics, 2013
We use the improved general mapping deformation method based on the generalized Jacobi elliptic functions expansion method to construct some of the generalized Jacobi elliptic solutions for some nonlinear partial differential equations in mathematical ...

Differentiable Randers‐Finsler Eikonal Solvers

Computer Graphics Forum, EarlyView.
Abstract Fast and differentiable solvers for anisotropic and asymmetric distance fields are a key primitive in geometry processing, enabling gradient‐based optimization over metrics, drift fields, and downstream objectives that depend on geodesic distances and geodesics.

Extended Jacobi Elliptic Function Expansion Method to the ZK-MEW Equation

International Journal of Differential Equations, 2011
The extended Jacobi elliptic function expansion method is applied for Zakharov-Kuznetsov-modified equal-width (ZK-MEW) equation. With the aid of symbolic computation, we construct some new Jacobi elliptic doubly periodic wave solutions and the ...

Fast Nodal Hessian Computation for Peridynamic Fracture Simulation

Computer Graphics Forum, EarlyView.
A fast, exact nodal Hessian computation for Non‐Ordinary State‐Based Peridynamics is introduced through analytical simplification and a warp‐centric GPU strategy. The method accelerates preconditioned solvers and Vertex Block Descent, enabling interactive fracture simulation with physical accuracy.

GPU-ACCELERATED SOLUTION OF THE 2D POISSON EQUATION: A COMPARATIVE STUDY OF JACOBI AND RED-BLACK GAUSS–SEIDEL METHODS WITH GLOBAL AND SHARED MEMORY

Journal of Problems in Computer Science and Information Technologies
The Poisson equation is a canonical elliptic partial differential equation (PDE) that arises in diverse fields such as electrostatics, fluid dynamics, and heat transfer.

Primal SPH Solver for Strongly Coupled Multiphase Simulations with High Density Ratios

Computer Graphics Forum, EarlyView.
Abstract In recent years, the Smoothed Particle Hydrodynamics (SPH) approach has been increasingly used for multiphase simulations involving interactions between diverse materials. A critical component of an SPH simulator is the pressure solver, which not only facilitates the simulation of compressible or incompressible fluids but also handles contact ...

The Politics of Pointing: Lessing's Fingerzeig and the Limits of Figural Reading

The German Quarterly, EarlyView.
Abstract Lessing's Fingerzeig—a “pointer” that guides without determining judgment—has often been treated as a stylistic habit rather than a hermeneutic principle. This essay reconstructs it as an ethics of interpretation, a gesture that orients without completing and leaves judgment to whoever follows.

Jacobi–Sobolev Orthogonal Polynomials, Differential Properties and Structural Formulas

Axioms
In this paper, we extend some differential and structural results for monic Jacobi–Sobolev orthogonal polynomials, associated with a general discrete Sobolev inner product, with a Jacobi continuous part. We consider finitely many exterior mass points and

Mixed Jacobi-Fourier spectral method for Fisher equation

Mathematical Modelling and Analysis, 2018
In this paper, we propose a mixed Jacobi-Fourier spectral method for solving the Fisher equation in a disc. Some mixed Jacobi-Fourier approximation results are established, which play important roles in numerical simulation of various problems deﬁned in ...

The Flip Side of Gender Segregation: Cross‐National and Temporal Variation in Men's Participation in Female‐Dominated Occupations

Gender, Work &Organization, EarlyView.
ABSTRACT Despite women's growing presence in male‐dominated occupations, men remain underrepresented in female‐typed occupations. This imbalance is commonly attributed to three factors: (1) the confinement of female‐typed occupations to a narrow range of stereotypical domains, (2) their lower socioeconomic rewards, and (3) the stigma men face in gender‐
