While averages and typical fluctuations often play a major role in understanding the behavior of nonequilibrium system, this nonetheless is not always true. Rare events large are also pivotal when thorough analysis system being done. In context, statistics extreme contrast to average plays an important role, as has been discussed fields ranging from statistical mathematical physics climate, fin...

Concept drift detection algorithms have historically been faithful to the aged architecture of forcefully resetting base classifiers for each detected drift. This approach prevents underlying becoming outdated as distribution a data stream shifts from one concept another. In situations where both and temporal dependence are present within stream, forced can cause complications in classifier eva...

We consider a class of systems with time-varying parameters, which are represented in the form linear regressions bounded disturbances. The task is to estimate such parameters under condition that regressor finitely exciting (FE). Considering problem statement, new robust method proposed identify error, could be reduced finite limit. For this purpose, unknown expanded into Taylor series order t...

Using methods of geometric dynamical systems modeling, we demonstrate the mechanism through which inhibitory feedback synapses to oscillatory neurons stabilize the oscillation, resulting in a flattened phase-resetting curve. In particular, we use the concept of a synaptic phase-resetting curve to demonstrate that periodic inhibitory feedback to an oscillatory neuron locks at a stable phase wher...

This paper deals with a prosodic comparison of spontaneous and read-aloud speech. More speci cally, the study reports data on F0 declination in these two speaking modes using Swedish materials. For both speaking styles the analysis revealed negative slopes, a steepness-duration dependency with declination being less steep in longer utterances than in shorter ones and resetting at utterance boun...

For a class of square continuous-time nonlinear controllers we design a suitable resetting rule inspired by the resetting rule for Clegg integrators and First Order Reset Elements (FORE).With this rule,we prove that the arising hybrid system with temporal regularization is passive in the conventional continuous-time sensewith a small shortage of input passivity decreasingwith the temporal regul...

The oscillatory phase-resetting model predicts that event-related potential (ERP) components are generated by a superposition of evoked oscillations with different frequencies. We investigate this question in a memory task in which human subjects had to retrieve a verbal label in response to the presentation of a picture. The results show that (i) evoked oscillations in the delta, theta, alpha ...

It has been suggested that chronic alcoholism may lead to altered neural mechanisms related to inhibitory processes. Here, we studied auditory N1 suppression phenomena (i.e. amplitude reduction with repetitive stimuli) in chronic alcoholic patients as an early-stage information-processing brain function involving inhibition by the analysis of the N1 event-related potential and time-frequency co...

Analyzing the S matrices associated with a host of relaxation processes allows one, using extra ‘‘chaperon’’ states, to construct a decoherence-free subspace ~DFS! that is immune to the effects of relaxation. The method does not require knowledge of the system-bath Hamiltonian, which is rarely known. Thus, a DFS can be constructed directly from experimentally determined relaxation and dephasing...

The master circadian oscillator in the hypothalamic suprachiasmatic nucleus is entrained to the day/night cycle by retinal photoreceptors. Melanopsin (Opn4), an opsin-based photopigment, is a primary candidate for photoreceptor-mediated entrainment. To investigate the functional role of melanopsin in light resetting of the oscillator, we generated melanopsin-null mice (Opn4-/-). These mice entr...
