Remarks on the Fractional Laplacian with Dirichlet Boundary Conditions and Applications [PDF]

International Mathematics Research Notices, 2016
We prove nonlinear lower bounds and commutator estimates for the Dirichlet fractional Laplacian in bounded domains. The applications include bounds for linear drift-diffusion equations with nonlocal dissipation and global existence of weak solutions of critical surface quasi-geostrophic equations.

Blow-Up Results for a Class of Quasilinear Parabolic Equation with Power Nonlinearity and Nonlocal Source

Journal of Function Spaces, 2021
This paper deals with a class of quasilinear parabolic equation with power nonlinearity and nonlocal source under homogeneous Dirichlet boundary condition in a smooth bounded domain; we obtain the blow-up condition and blow-up results under the condition

Context‐centric proactive information delivery for Knowledge Work support: Opportunities, challenges, and directions. An Annual Review of Information Science and Technology (ARIST) paper

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Context‐centric proactive information delivery (PID) is a relatively underexplored domain within recommender systems (RS) aimed at enhancing Knowledge Workers' productivity by proactively providing relevant information during digital tasks.

Two New Analytical Models for Three‐Dimensional Transport in a Confined Aquifer With a Permeable Reactive Barrier: A New Adsorptive‐Reactive Robin Matching Condition

Water Resources Research
Existing analytical models for permeable reactive barriers (PRBs) treat an upgradient aquifer formation with contaminant sources as either a Dirichlet or Robin boundary condition specified at the upgradient face of the PRB.

On a Class of Nonuniformly Nonlinear Systems with Dirichlet Boundary Conditions [PDF]

Ukrainian Mathematical Journal, 2015
The authors apply the classical Ambrosetti-Rabinowitz-Mountain Pass Theorem to establish the existence of at least two weak solutions to the following boundary value problem for a nonuniformly elliptic system \[ -\Delta_p u-\operatorname{div}(h_1(|\nabla u|^p)|\nabla u|^{p-2}\nabla u)=F_u(x,u,v)\text{ in }\Omega, \] \[ -\Delta_q u-\operatorname{div ...

Incremental refinement of relevance rankings: Balancing relevance depth and scope

Journal of the Association for Information Science and Technology, EarlyView.
Abstract Delivering both relevant and topically diverse results is a key challenge in information retrieval (IR). This study introduces a hybrid method that incrementally refines rankings by combining probabilistic topic modeling (latent dirichlet allocation [LDA]) with citation‐based pennant retrieval grounded in Relevance Theory (RT), optimizing for ...

Modeling of Chloride Distribution in Cement-Based Materials with Neumann Boundary Condition

Advances in Materials Science and Engineering, 2018
The nonstable transport of chloride in cement-based materials, including diffusion, convection, and chloride binding, is described as a general form of Fick’s law.

Reporting What Matters, or Reporting What Looks Good? Materiality and Balance in Post–Rana Plaza Apparel Sustainability Disclosure

Business Strategy and the Environment, EarlyView.
ABSTRACT Sustainability reports (SRs) are widely criticized for vague disclosures and selective emphasis on positive outcomes, yet systematic research on two core SR challenges remains limited: materiality (whether disclosed content is relevant) and balance (whether both achievements and challenges are reported).

The weak solutions of a nonlinear parabolic equation from two-phase problem

Journal of Inequalities and Applications, 2021
A nonlinear parabolic equation from a two-phase problem is considered in this paper. The existence of weak solutions is proved by the standard parabolically regularized method.
