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

Advanced Intelligent Systems, EarlyView.This review explores how shape‐changing structures—origami, bistable, and laminate structures—enable multifunctionality in soft robotics and metamaterials. Starting from structural design, it examines core principles, real‐world applications, and ongoing challenges.

Nonlinear eigenvalues and mountain pass methods
Topological Methods in Nonlinear Analysis, 1993 The authors give a detailed account of mountain pass lemmas for \(C^ 1\) functionals \(G\) on a Hilbert space, where the admissible paths are restricted to fixed regions. A typical example for such a region is the set \(\{u\): \(u\in H\), \(F(u)\leq R\}\), where \(F\) is another \(C^ 1\) functional and \(R>0\).

Planning and Control Framework for a Quadruped Robot With Changeable Configuration
Advanced Intelligent Systems, EarlyView.Multiconfiguration quadruped robots enhance adaptability by switching between mammal‐like and reptile‐like morphologies. This study presents a nonlinear constraint‐based motion planner integrated with a hierarchical whole‐body controller, enabling robust configuration switching and locomotion on complex terrains. Experiments on slopes, irregular bricks,

Wind‐driven seed dispersal differentially promotes seed trapping and retention across alpine plants
American Journal of Botany, EarlyView.Abstract Premise Seed dispersal can mediate species interactions between plants across life stages. Plants can physically stop seed movement (seed trapping) and prevent further dispersal following entrapment (seed retention). We therefore hypothesized seed trapping and retention rates depend on the physical attributes of interacting seeds and plants ...

Structural problems without structural solutions? Youth leaders' perceptions of their community
American Journal of Community Psychology, EarlyView.Abstract As young people explore and reflect on the conditions of their neighborhoods and communities, they can forge a critical consciousness—merging their perspectives and analysis to direct both individual and collective actions. Photovoice is a methodological tool that allows participants to document their perspectives and analysis and discuss with

Mountain pass solutions for a mean field equation from two-dimensional turbulence
, 2006 Using Struwe's "monotonicity trick" and the recent blow-up analysis of Ohtsuka and Suzuki, we prove the existence of mountain pass solutions to a mean field equation arising in two-dimensional turbulence.Comment: 13 ...

American Journal of Industrial Medicine, EarlyView.ABSTRACT Background Since 1997 the Building Trades National Medical Screening Program (BTMed) has offered medical exams to construction workers employed in US nuclear weapons facilities. The process consists of two steps: (1) a detailed work history interview; and (2) a medical exam.
