Dual-Dual Formulation for a Contact Problem with Friction [PDF]

open access: yesComputational Methods in Applied Mathematics, 2015
Abstract A variational inequality formulation is derived for some frictional contact problems from linear elasticity. The formulation exhibits a two-fold saddle point structure and is of dual-dual type, involving the stress tensor as primary unknown as well as the friction force on the contact surface by means of a Lagrange multiplier ...

Effects of Different Montages of Transcranial Direct Current Stimulation on Haemodynamic Responses and Motor Performance in Acute Stroke: A Randomized Controlled Trial

open access: yesJournal of Rehabilitation Medicine, 2022
Objective: Transcranial direct current stimulation (tDCS) has shown positive results in neurorehabilitation. However, there is limited evidence on its use in acute stroke, and unclear evidence regarding the best tDCS montage (anodal-, cathodal-, or ...

Dual subtractions [PDF]

open access: yesJournal of High Energy Physics, 2021
Abstract We propose a novel local subtraction scheme for the computation of Next-to-Leading Order contributions to theoretical predictions for scattering processes in perturbative Quantum Field Theory. With respect to well known schemes proposed since many years that build upon the analysis of the real radiation matrix elements ...

Dual infection with dengue virus 3 and human immunodeficiency virus 1 in Havana, Cuba

open access: yesJournal of Infection in Developing Countries, 2009
Although dengue virus (DEN) endemic regions overlap with human immunodeficiency virus 1 (HIV) high incidence areas, little has been documented on HIV and DEN mixed infection. Here we report DEN/HIV concurrent infections recorded during the DEN-3 epidemic
