Gibbs oscillations in the truncated spectral representation of the earth's topography are strongly reduced by determining its spectral coefficients as a minimum of a nonuniformly weighted, nonquadratic cost function. The cost function penalizes the difference between spectral and true topography with weights that are explicit functions of the topographic height and its gradient. The sensitivity...

There is a great deal of evidence for the existence of metabolic oscillations in pancreatic β-cells. Mechanisms that have been proposed for these oscillations include glycolytic oscillations; oscillations due to the feedback of Ca2+ onto the mitochondrial inner membrane and on dehydrogenases; and oscillations intrinsic to the tricarboxylic (TCA) cycle or the downstream reactions of oxidative ph...

Altered neural oscillations and their abnormal synchronization are crucial factors in the pathophysiology of several neuropsychiatric disorders. There is increasing evidence that the perturbation with an abnormal increase of spontaneous thalamocortical neural oscillations lead to a phenomenon termed Thalamocortical dysrhythmia (TCD) which underlies the symptomatology of a variety of neurologica...

We report time- and angle-resolved photoemission spectroscopy (trARPES) measurements on the Sb(111) surface. observe band- momentum-dependent binding-energy oscillations in bulk surface bands driven by ${A}_{1g}$ ${E}_{g}$ coherent phonons. While band shows simultaneous oscillations, show either or oscillations. The observed behavior is reproduced frozen-phonon calculations based density functi...

We present the experimental observation of Bloch oscillations, the Wannier-Stark ladder, and Landau-Zener tunneling of surface acoustic waves in perturbed grating structures on a solid substrate. A model providing a quantitative description of our experimental observations, including multiple Landau-Zener transitions of the anticrossed surface acoustic Wannier-Stark states, is developed. The us...

The effective interaction potential for charged particles is calculated in the deuterium plasma formed in the surface region of the palladium cathode in the electrolysis of heavy water. It is shown that the Coulomb potential is overscreened producing, at certain distances, an attractive potential between deuterium nuclei pairs and also between the deuterium nuclei and the surface atoms. This be...

The standard pharmacological treatment for Parkinson's disease using the dopamine precursor levodopa is unfortunately limited by gradual development of disabling involuntary movements for which the underlying causes are poorly understood. Here we show that levodopa-induced dyskinesia in hemiparkinsonian rats is strongly associated with pronounced 80 Hz local field potential oscillations in the ...
