Efficient primary and parametric resonance excitation of bistable resonators [PDF]
AIP Advances, 2016 We experimentally demonstrate an efficient approach to excite primary and parametric (up to the 4th) resonance of Microelectromechanical system MEMS arch resonators with large vibrational amplitudes.

Functional magnetic resonance imaging in primary hyperparathyroidism [PDF]
European Journal of Endocrinology, 2020 Objective The neurophysiological mechanisms underlying cognitive dysfunction in primary hyperparathyroidism (PHPT) and the brain regions affected are not clear. We assessed neural activation during cognitive testing (matrix reasoning, paired associates, and logical memory) using functional MRI (fMRI) in 23 patients with PHPT and 23 healthy controls. A

Preliminary measurements of T-T90 using acoustic gas thermometer in neon gas
Measurement: Sensors, 2021 The measurements of the difference between the thermodynamic temperature T and the temperature T90 based on the International Temperature Scale of 1990 (ITS-90), (T-T90), by using an acoustic gas thermometer (AGT) working on neon gas is reported in this ...

Effects of Nonlinear Damping on Vibrations of Microbeam
Applied Sciences, 2022 The present paper develops a new Bernoulli–Euler theory of microbeams for the consideration of small-scale effects and nonlinear terms, which are induced by the axial elongation of the beam and Kelvin–Voigt damping.
