COVID‑19 mitigation by digital contact tracing and contact prevention (app‑based social exposure warnings)
(2021-07-13)
A plethora of measures are being combined in the attempt to reduce SARS-CoV-2 spread. Due to its sustainability, contact tracing is one of the most frequently applied interventions worldwide, albeit with mixed results. We ...
Time-dependent contact mechanics
Contact geometry allows us to describe some thermodynamic and dissipative systems. In this paper we introduce a new geometric structure in order to describe time-dependent contact systems: cocontact manifolds. Within this ...
Association between Contact with Nature and Anxiety, Stress and Depression Symptoms: A Primary Survey in Brazil
(Mdpi, 2022-09-01)
Mental health benefits have been linked to human interaction with nature. However, most studies have been carried out in developed countries, limiting the generalizability of empirical findings to other parts of the world. ...

Characterising circular-arc contact B0–VPG graphs
(Elsevier Science, 2020-09)
A contact B0–VPG graph is a graph for which there exists a collection of nontrivial pairwise interiorly disjoint horizontal and vertical segments in one-to-one correspondence with its vertex set such that two vertices are ...
A nonsmooth frictional contact formulation for multibody system dynamics
(John Wiley & Sons Ltd, 2020-08-07)
We present a new node-to-face frictional contact element for the simulation of the nonsmooth dynamics of systems composed of rigid and flexible bodies connected by kinematic joints. The equations of motion are integrated ...
Contact endoscopy for identifying the parathyroid glands during thyroidectomy
(PACINI EDITORE, 2010)
Aim of this study was to analyse contact endoscopy as an auxiliary method for identifying parathyroid glands during thyroid surgery and to identify other variables that may interfere with this correlation. overall, 125 ...
Characterization and interaction of geometric and contact/impact nonlinearities in dynamical systems
(2022-03-15)
In this work, we study how a contact/impact nonlinearity interacts with a geometric cubic nonlinearity in an oscillator system. Specific focus is shown to the effects on bifurcation behavior and secondary resonances (i.e., ...
Modelling and simulation of a direct contact rotary dryer
(MARCEL DEKKER INC, 1996)
A mathematical model able to predict solid and drying gas temperature and moisture content axial profiles along a direct contact rotary dryer was developed. The study was focused on the drying kinetics based on phenomenological ...
