Periodic solutions for second-order Hamiltonian systems with the p-Laplacian
Electronic Journal of Differential Equations, 2006 In this paper, we investigate the periodic solutions of Hamiltonian system with the p-Laplacian. By using Mountain Pass Theorem the existence of at least one periodic solution is obtained, Furthermore, under suitable assumptions, we obtain the ...

Construction of a Feedback Comment Analysis Model for Evaluation of Endoscopic Surgical Skill
Annals of Gastroenterological Surgery, EarlyView.ABSTRACT Background Surgical education and skill assessments are important in improving surgical skills. However, instructors' comments tend to be complex and unorganized, with varying content and categories. This study aimed to develop a natural language processing (NLP) model to automatically classify feedback comments on surgical procedures and ...

Existence Results for a critical fractional equation
, 2016 We are concerned with existence results for a critical problem of Brezis-Nirenberg Type involving an integro-differential operator. Our study includes the fractional Laplacian. Our approach still applies when adding small singular terms.

Annals of Gastroenterological Surgery, EarlyView.ABSTRACT Background The annual number of pancreatoduodenectomies (PDs) in the United States has increased over the past decade, but the facility types driving this growth and whether outcomes have improved remain unclear. We aimed to identify characteristics of facilities with increasing PD volumes and assess national trends in centralization ...

Existence and multiplicity of solutions for divergence type elliptic equations
Electronic Journal of Differential Equations, 2011 We establish the existence and multiplicity of weak solutions of a problem involving a uniformly convex elliptic operator in divergence form. We find one nontrivial solution by the mountain pass lemma, when the nonlinearity has a $(p-1)$-superlinear ...

Beyond the Mountain Pass: Some Applications
Advanced Nonlinear Studies, 2012 Abstract We will survey three applications of the famous Mountain Pass Lemma by Antonio Ambrosetti and Paul H. Rabinowitz, [6]. Precisely, we will present some results on the following problems: A model of growth and roughening of surfaces, usually called Kardar-Parisi-Zhang model. A supercritical problem
