Nonlocal Boundary Value Problem for Nonlinear Impulsive qk-Integrodifference Equation
Abstract and Applied Analysis, 2014 A nonlinear impulsive integrodifference equation within the frame of qk-quantum calculus is investigated by applying using fixed point theorems. The conditions for existence and uniqueness of solutions are obtained.

Controllable Intrinsic Surface Pattern Generation Using Slime Mold Simulations
Computer Graphics Forum, EarlyView.Abstract Surface‐based pattern simulations have proven valuable for texture design and scientific visualization, but existing methods face several limitations. Most simulations either target a narrow range of pattern types (e.g. spots, branching) or support a broad range of patterns at the cost of time‐consuming parameter tuning.

Positive Solutions for a Nonlocal Boundary-Value Problem with Increasing Response [PDF]
, 2000 We study a nonlocal boundary-value problem for a second order ordinary differential equation. Under a monotonicity condition on the response function, we prove the existence of positive solutions ...

Volumetric Inverse Rendering via Neural Radiative Transfer
Computer Graphics Forum, EarlyView.Abstract Volumetric inverse rendering seeks to recover the optical properties of participating media from images. Existing approaches either rely on differentiable stochastic light transport simulation, which require substantial algorithmic effort, or use simplified models that fail to capture global illumination.

An Approximation of Semigroups Method for Stochastic Parabolic Equations
Abstract and Applied Analysis, 2012 A single-step difference scheme for the numerical solution of the nonlocal-boundary value problem for stochastic parabolic equations is presented. The convergence estimate for the solution of the difference scheme is established.
