Consensus on the use of thoracic ultrasound by respiratory physiotherapists: how, where and for what?
Ultrasonography (US) is a non-invasive and safe form of thoracic assessment, offering real-time imaging without ionizing radiation exposure. Point-of-care ultrasound (POCUS) is a form of immediate assessment and monitoring of the ...

Na pandemia da COVID-19, a educação presencial foi transferida para a modalidade ensino remoto emergencial, na expectativa de reduzir as nocividades que seriam promovidas pela suspensão das aulas. Frente a essa transição, propôs-se, ...
On computation of the logarithm of the Chen-Fliess series for nonlinear systems
We obtain expressions for the logarithm of the Chen-Fliess series for a nonlinear control system. This logarithm provides an alternative to Sussmann’s exponential product expansion of the Chen-Fliess series. We also formulate a rule...
A class of sub-elliptic equations on the Heisenberg group and related interpolation inequalities
We firstly prove the existence of least energy solutions to a class of sub-elliptic equations on the Heisenberg group. Then we use this least energy solution to give a sharp estimate to the smallest positive co...
