Hybrid Newton-type method for a class of semismooth equations [PDF]
, 2002 In this paper, we present a hybrid method for the solution of a class of composite semismooth equations encountered frequently in applications. The method is obtained by combining a generalized finite-difference Newton method to an inexpensive direct ...

On a logarithmic Hartree equation
Advances in Nonlinear Analysis, 2019 We study the existence of radially symmetric solutions for a nonlinear planar Schrödinger-Poisson system in presence of a superlinear reaction term which doesn’t satisfy the Ambrosetti-Rabinowitz condition. The system is re-written as a nonlinear Hartree

Existence and multiplicity of solutions for resonant-superlinear problems
, 2023 We consider a semilinear Dirichlet problem with a reaction which exhibits an asymmetric behaviour as x →±∞ (it is superlinear as x →+∞ and resonant as x →−∞). Using variational tools from the critical point theory, together with truncation and comparison

Solutions and positive solutions for superlinear Robin problems [PDF]
, 2019 We consider nonlinear, nonhomogeneous Robin problems with a (p - 1)-superlinear reaction term, which need not satisfy the Ambrosetti-Rabinowitz condition. We look for positive solutions and prove existence and multiplicity theorems.

Multiple solutions for superlinear fractional p-Laplacian equations [PDF]
We study a Dirichlet problem driven by the (degenerate or singular) fractional p-Laplacian and involving a (p-1)-superlinear reaction at infinity, not necessarily satisfying the Ambrosetti–Rabinowitz condition.

Advanced Robotics Research, EarlyView.Rotating magnetic fields (RMFs) are widely used for microrobot propulsion and control. We show that RMF generation with permanent magnets is mechanically feasible for many limb and intracranial applications but becomes constrained for thoracic targets.

Distributed Micropneumatic Sensors for Soft Robots to Detect Touch and Pose
Advanced Robotics Research, EarlyView.Soft robots need integrated touch and pose sensing for safe and reliable operation. This work presents a three‐fingered soft gripper with 18 micropneumatic sensors made from the same materials as its pneumatic actuators. By measuring airflow resistance changes in deforming microchannels of the sensors, finger pose and contact are detected, enabling ...

Concave-Convex Problems for the Robin p-Laplacian Plus an Indefinite Potential
Mathematics, 2020 We consider nonlinear Robin problems driven by the p-Laplacian plus an indefinite potential. In the reaction, we have the competing effects of a parametric concave (that is, ( p − 1 ) -sublinear) term and of a convex (that is, ( p −
