On the critical forcing amplitude of forced nonlinear oscillators
(De Gruyter, 2013-12)
The steady-state response of forced single degree-of-freedom weakly nonlinear oscillators under primary resonance conditions can exhibit saddle-node bifurcations, jump and hysteresis phenomena, if the amplitude of the ...
Effects of the body force on the pedestrian and the evacuation dynamics
(Elsevier Science, 2020-09)
The Social Force Model (SFM) is a suitable model for describing crowd behaviors under emotional stress. This research analyzes the role of the body force in the original SFM. We focused on the parameter associated with the ...
Reorganized Force Control in Elbow Pain Patients during Isometric Wrist Extension
(Lippincott Williams, 2018-08)
Introduction: Reorganized force control may be an important adaptation following painful traumas. In this study, force control adaptations were assessed in elbow pain patients. Increasing the contraction demand may overcome ...
Periodic motions in forced problems of Kepler type
(Birkhauser Verlag Ag, 2011-12)
A Newtonian equation in the plane is considered. There is a central force (attractive or repulsive) and an external force λh(t), periodic in time. The periodic second primitive of h(t) defines a planar curve and the number ...
Quantitative study of FORC diagrams in thermally corrected Stoner– Wohlfarth nanoparticles systems
(Elsevier Science, 2016-12-01)
The use of FORC diagrams is becoming increasingly popular among researchers devoted to magnetism and magnetic materials. However, a thorough interpretation of this kind of diagrams, in order to achieve quantitative ...
Path suppression of strongly collapsing bubbles at finite and low Reynolds numbers
(American Physical Society, 2013-06-03)
We study, numerically and experimentally, three different methods to suppress the trajectories of strongly collapsing and sonoluminescent bubbles in a highly viscous sulfuric acid solution. A new numerical scheme based on ...
Three-nucleon forces in the 1/Nc expansion
(American Physical Society, 2013-09)
The operator structures that can contribute to three-nucleon forces are classified in the 1/Nc expansion. At leading order in 1/Nc a spin-flavor independent term is present, as are the spin-flavor structures associated ...
Quantum treatment of Verlinde's entropic force conjecture
(Elsevier Science, 2018-12)
Verlinde conjectured that gravitation is an emergent entropic force. This surprising conjecture was proved in Plastino and Rocca (2018) within a purely classical context. Here, we appeal to a quantum environment to deal ...
Error analysis of forced discrete mechanical systems
(American Institute of Mathematical Sciences, 2021-12)
The purpose of this paper is to perform an error analysis of the variational integrators of mechanical systems subject to external forcing. Es- sentially, we prove that when a discretization of contact order r of the La- ...
Thermostatistics of overdamped motion with anisotropic drag forces
(EDP Sciences, 2020-03)
We investigate the consequences of anisotropic drag forces for the thermostatistics of systems of interacting particles in the overdamped motion regime. Systems of confined particles interacting via short-range forces and ...
