It is becoming increasingly apparent that brain oscillations in various frequency bands play important roles in perceptual and attentional processes. Understandably, most of the associated experimental evidence comes from human or animal electrophysiological studies, allowing direct access to the oscillatory activities. However, such periodicities in perception and attention should, in theory, ...

For a long time alpha oscillations have been functionally linked to the processing of visual information. Here we propose an new theory about the functional meaning of alpha. The central idea is that synchronized alpha reflects a basic processing mode that controls access to information stored in a complex long-term memory system, which we term knowledge system in order to emphasize that it com...

A common finding across many reaction time tasks is that people slow down on trials following errors, a phenomenon known as post-error slowing. In the present study, we tested a novel hypothesis about the neural mechanism underlying post-error slowing. Recent research has shown that when task-relevant stimuli occur in a rhythmic stream, neuronal oscillations entrain to the task structure, there...

This paper presents a review and discussion on the numerical studies on steady and unsteady flow in collapsible channels using both the fluid-membrane model and the fluid-beam model. The aim of the research is to explore the possible mechanisms of self-excited oscillations observed in experiments on flow in collapsible tubes. The existence and stability of the steady solutions for different con...

The functional relevance of brain oscillations in the alpha frequency range (8-13 Hz) has been repeatedly investigated through the use of rhythmic visual stimulation. The underlying mechanism of the steady-state visual evoked potential (SSVEP) measured in EEG during rhythmic stimulation, however, is not known. There are two hypotheses on the origin of SSVEPs: entrainment of brain oscillations a...

Abstract The article presents the results of calculating saw gasket vibrations in steady state operation linter machine. It was established that stable position equilibrium is achieved machines. To determine machine, calculations were conducted with expansion into a series kinetic and potential energies. As result calculations, frequency period oscillations determined under steady-state machine...

It has long been known that quantum particles moving in a periodic lattice and subject to constant force field undergo an oscillatory motion is referred as Bloch Oscillations (BOs). However, it also that, under quite general conditions, biased mesoscopic system connected leads should settle steady-state regime characterized by electric current (described the Landauer formula). Since both effect...

This paper offers projections of future transmission dynamics for SARS-CoV-2 in an SEIRS model with demographics and waning immunity. In a stylized optimal control setting calibrated to the United States, we show that disease is endemic steady state its are characterized by damped oscillations. The magnitude oscillations depends on how fast immunity wanes. social distancing policy both curbs pe...
