Stochastic resonance in periodic potentials: realization in a dissipative optical lattice

, 2002
We have observed the phenomenon of stochastic resonance on the Brillouin propagation modes of a dissipative optical lattice. Such a mode has been excited by applying a moving potential modulation with phase velocity equal to the velocity of the mode. Its

Multi-consensus formation control by artificial potential field based on velocity threshold

Frontiers in Neuroscience
This study proposes a multi-consensus formation control algorithm by artificial potential field (APF) method based on velocity threshold. The algorithm improves the multi-consensus technique. This algorithm can split a group of agents into multiple agent

Critical points of the cosmic velocity field and the uncertainties in the value of the Hubble constant

, 2016
The existence of critical points for the peculiar velocity field is a natural feature of the correlated vector field. These points appear at the junctions of velocity domains with different orientations of their averaged velocity vectors.

On the Binding Energy of Atoms in Crystals of Noble Gases and Metals and the Speed of Sound

Crystals
The speed of sound depends on the structure and material properties of the crystal, such as density and Young’s modulus. On the other hand, from atomistic arguments it is possible to associate Young’s modulus with other material properties.

Pressure and Velocity Profiles over a Weir Using Potential Flow Model

Fluids
A potential flow model of the semi-inverse type is proposed to simulate flow over round crested weirs. This technique involves the construction of only streamlines over the weir instead of constructing the entire flow net.

Limb immobilization alters functional electrophysiological parameters of sciatic nerve

Brazilian Journal of Medical and Biological Research, 2013
Immobilization, used in clinical practice to treat traumatologic problems, causes changes in muscle, but it is not known whether changes also occur in nerves.
