Simple Synchronous and Asynchronous Algorithms for Distributed Minimax Optimization

SICE Journal of Control, Measurement, and System Integration, 2017
Synchronous and asynchronous algorithms are presented for distributed minimax optimization. The objective here is to realize the minimization of the maximum of component functions over the standard multi-agent network, where each node of the network ...

(N,q)$(N,q)$‐Laplacian equations with one‐sided critical exponential growth

Mathematische Nachrichten, Volume 299, Issue 3, Page 675-698, March 2026.
Abstract We prove the existence of two non‐trivial weak solutions for a class of quasilinear, non‐homogeneous elliptic problems driven by the (N,q)$(N,q)$‐Laplacian with one‐sided critical exponential growth in a bounded domain Ω⊂RN$\Omega \subset \mathbb {R}^{N}$. The first solution is obtained as a local minimizer of the associated energy functional;

Multiplicity of Solutions for Neumann Problems for Semilinear Elliptic Equations

Abstract and Applied Analysis, 2014
Using the minimax methods in critical point theory, we study the multiplicity of solutions for a class of Neumann problems in the case near resonance. The results improve and generalize some of the corresponding existing results.

Safety and Efficacy of Lucitanib Plus Toripalimab in Advanced Solid Tumors Refractory to Standard Therapies: An Open‐Label, Multicenter, Phase II Study

MedComm, Volume 7, Issue 3, March 2026.
Lucitanib plus toripalimab showed manageable safety and encouraging antitumor activity in advanced solid tumors, particularly in PD‐1‐refractory nasopharyngeal carcinoma and recurrent endometrial carcinoma. Clinical responses were observed across subgroups regardless of prior immunotherapy.

The Existence of Periodic Solutions for Non-Autonomous Differential Delay Equations via Minimax Methods

Advances in Difference Equations, 2009
By using variational methods directly, we establish the existence of periodic solutions for a class of nonautonomous differential delay equations which are superlinear both at zero and at infinity.

Advances in Modal Regression: From Theoretical Foundations to Practical Implementations

WIREs Computational Statistics, Volume 18, Issue 1, March 2026.
Modal regression. ABSTRACT Modal regression has emerged as a powerful alternative to traditional mean and quantile regression by focusing on estimating the conditional mode rather than the conditional mean or quantiles. This approach offers robustness to outliers and skewed distributions while providing more informative prediction intervals for ...

Existence of Subharmonic Solutions for a Class of Second-Order p-Laplacian Systems with Impulsive Effects

Journal of Applied Mathematics, 2012
By using minimax methods in critical point theory, a new existence theorem of infinitely many periodic solutions is obtained for a class of second-order p-Laplacian systems with impulsive effects. Our result generalizes many known works in the literature.

Existence and multiplicity results for nonlinear elliptic problems in $R^N$ with an indefinite functional

Electronic Journal of Differential Equations, 2002
We prove the existence of a nontrivial solution for the nonlinear elliptic problem $-Delta u=lambda h(x)u + a(x)g(u)$ in $R^N$, where $g$ is superlinear near zero and near infinity, $a(x)$ changes sign, $lambda $ is positive, and $h(x)geq 0$ is a weight ...

Existence of Solutions to Boundary Value Problems for the Discrete Generalized Emden-Fowler Equation

Discrete Dynamics in Nature and Society, 2009
We consider the existence of solutions to boundary value problems for the discrete generalized Emden-Fowler equation. By means of the minimax methods in the critical point theory, some new results are obtained.
