Any opinions in the examples do not represent the opinion of the Cambridge Dictionary editors or of Cambridge University Press or its licensors. His bursts of creative work were followed by periods of exhaustion, and these were often prolonged by pecuniary worry and under-nourishment. Specifically, pregnant monkeys were placed in cages in a darkened room and exposed to unpredictable loud bursts of noise. In the case of autism, binding-related gamma bursting looks very similar to that in controls, apart from not being modulated by face inversion. The laser builds up energy at a bounded rate and operation in this manner allows for large bursts of energy. Of the monolingual speakers, one male and two female speakers produced 25, 16.7 and 45.4% of the tokens without clear bursts. During this phase, bursts of violence were frequent in the city. If only bursting responses were decoded, for instance, this would be likely to bias coding in the direction of localism. The increase in bursting seemed to continue for up to twelve hours after training. Neurons summate inputs and fire in bursts, other neurons react with longer latencies, the sensory signal is repeatedly reorganized, and the activity eventually dissipates. The fluctuations grow exponentially at first and develop into turbulence without being accompanied by abrupt bursts or turbulent spots. Why are long periods of political stability punctuated by sudden bursts of intense instability? Such bursts are noted in the 1830s, the 1910s and the 1940s but not, rather surprisingly, in the 1980s. The flow characteristics as well as the bursting behaviour were studied in detail. The foster brother bursts in and throws a net that captures all the courtiers. The production of intense radiation bursts, by the electron beam during the reflection process, was also demonstrated. Absence of such bursts, therefore, is a major indicator of lenition. The canecutter chopping away at the crop bursts out in a spate of obscene words, a natural gush from the gut. In these bifurcations either a periodic orbit or a periodic interval disappears to give rise to chaotic bursts. The outer non-turbulent flow appears to be 'riding ' over the bumps or bursts of the interface. All detected bursts or sweeps have been aligned with respect to ti before averaging is carried out. Once again, there is a transition through more complicated intermittent bursts to largescale plumes. Conventional and conditional statistics are presented, relative to the occurrence of bursts and sweeps detected using a modified u-level method. Therefore, it seems unlikely that thalamic bursting is the result of transmission of bursting activity from the periphery. Therefore, the neuronal bursts that are recorded during tremor induce a periodic behavior that is perpetuated along this deregulated loop. The hyperpolarizations were strong enough to evoke low-threshold rebound bursts when the period between stimuli was long enough. In some cases, bursts may produce sufficient spike-frequency adaptation to delay and reduce subsequent tonic firing. There were no short, highfrequency bursts such as those associated with low-threshold calcium spikes. Moreover, these errors tend to synchronize bursts slightly. If there were no bursts, then these delays should be uncorrelated, which would be reflected in the correlogram. The ver tical dashed line separating the peaks shows the criterion used for clustering the spikes into bursts. Inspection of experimental records allowed tracing of the flickery pattern of activity within bursts to the presence of conductance substates. A second cluster, at the lower left with prespike and postspike intervals 4 ms, is the second to penultimate spikes in bursts. Changing patterns of spontaneous bursting activity of on and off retinal ganglion cells during development. Synchronous bursts of action potentials in ganglion cells of the developing mammalian retina. If such bursts are included in the average, the mean firing rate will increase and the percentage difference between responses will decrease. Secondly, ipsilateral stimulation generated relatively prolonged discharges of low-amplitude spiking that were distinct from the high-amplitude bursts evoked by contralateral stimulation. Conversely, "bursts" of action potentials could occur without a subsequent eye movement (the activity is not sufficient). Synaptic connections involved in the spontaneous correlated bursts in the developing tur tle retina. Gamma-ray bursts : accumulating afterglow implications, progenitor clues, and prospects. From the space-time auto-correlation of the intermittency function, one may conclude that the individual turbulent bursts are solitary and that they occur at random. When it comes to this kind of progress, controversy bursts out, and we can hardly do without an explicit definition. No marked bursts of turbulence are found in the wave-form. On the other hand, the secondary flow impinges on the outer bend and this tends to suppress bursting there. The conversion between time- and lengthscales requires the convection velocity of bursts and sweeps to be known. Conventional and conditional correlations between any two signals are examined, particularly for evidence of low-speed streaks in relation to bursts. Note the smooth behaviour of the time-averaged spectra as opposed to the bursting behaviour at individual times. Another feature of our numerical experiments is the appearance of intermittent bursts. The transition is typically associated with intermittent bursts, which may involve spatially modulated oscillations and merging or splitting of individual plumes. In autism, apparently normal bursts of gamma activity occurred, but the bursts were not different for the upright and inverted faces. Conversely, long-distance cortical-cortical connectivity would be decreased because its development depends on spatiotemporally coherent bursts of activity. Thus, the association between intense emotional experience and vagal withdrawal is functional, facilitating bursts of metabolic output in situations of danger. However, measurement of the timing of recall showed bursts of 2, 3, or 4 items clustered together, and occasionally 5 items in a cluster. Field samples and laboratory samples were cross-sectioned using a surface sterilized hacksaw and loose material removed using short bursts of compressed air. Care-giving is likely to be distributed in very short bursts to multiple clients. However, to do so it is first necessary to identify the bursts and their statistics [36, 43-46]. The question bursts forth like a cry from the troubled depdis of her womanly heart - and the spell is broken. Data from three arrays, considering electrodes with bursting behavior only. In contrast to the above analysis for electrodes with bursts, 33-40% of electrodes showed activity without bursts at 14-19 spikes minute21. As a third step, these short bursts were reassembled to create sustained textures of sound. Under sticky prices, there exist equilibrium paths in which an asset-price bubble temporarily develops and eventually bursts. The motet unfolds in a series of short bursts of rhythmic activity, each leading to a point of stasis lasting a perfect long. Economies with this trait continually evolve to "critical" configurations where minor shocks cause large bursts of activity. The cellular mechanisms that support thalamic bursting have not been established yet. Second, the pattern of firing seen in somatosensory cells during sleep is also best explained by assuming the presence of many single-spike bursts. However, roughly 5-10% of action potentials classified as tonic firing may actually be bursts. They fired bursts of spikes after saccades, but were also activated during the intersaccadic drift periods. In these experiments, the response to the majority of cycles of the visual response was in tonic mode, but bursts were occasionally seen. The spikes organize themselves in bursts or appear in isolation. The rationale for using agglomerative hierarchical clustering was that bursts are clusters of spikes and this method is the most common form of cluster analysis. Because receptive-field variability is likely to be linked to dendritic tree and synaptic-input variability, it is not surprising that bursts would be variable too. However, not all bursts were synchronized with bursts in neighbor cells. The relative slowness of the bursts in tur tles when compared to cats and ferrets should reflect itself in a slower propagation of waves. Second, at least two factors contribute to the excitability during bursts. From 56 cells analyzed in this manner, 52 (93%) were bursting and these are the cells repor ted in this study. In this paper, we use cluster analysis to find the bursts and study their temporal proper ties in tur tle. High frequency, synchronized bursting drives eye-specific segregation of retinogeniculate projections. A transient network of intrinsically bursting starburst cells underlies the generation of retinal waves. The data blocks are interleaved and spread into pieces in interleaving, which are combined with flags to build up the bursts. In fact, bursts of action potentials displayed practically the same frequency, whereas tonic spikes showed a clear dependence on the injected current. The two bursts presented at a shorter time scale illustrate the intrinsic characteristics which indicate that they originate from a low threshold calcium spike. When fruits are ripe, the capsule bursts open to present the seeds. However, bursts appearing in the first 500 ms following stimulus onset were the longest. Only bursts that were oscillatory (duration 30 ms) and whose frequency fell within the frequency range analyzed were included in the analysis. Biological effects of gamma-ray bursts inefficient as the c radiation would be deposited on the atmosphere itself. Possible radiation sources include flares from late-type parent stars, gamma-ray bursts, and gamma-ray lines from supernovae. Furthermore, due to their relatively large scale, these structure may also drive large-scale transport events in magnetically confined plasmas, such as bursts or avalanches. The systematic positive value in the turbulent zones show that, in the average, the turbulent bursts move away from the wall into the potential flow. Table 1 shows the elimination of bursting behavior by addition of glutamate without added astroglia. Spiking activity was more frequent with added astroglia and more bursts were apparent. The word "courts", for example, has a very striking dependence on document number, with several large bursts in the last few documents. The beams are emitted in bursts of picosecond duration, three orders of magnitude shor ter than conventional accelerator bunches. We have termed this tonic firing, but perhaps an equally plausible explanation for this is that it represents single-spike bursts. In any case, these criteria affect only quantitative estimates of bursting but not the broader, qualitative conclusions of the study (see below). The other kind was between the same variables extracted from synchronized bursts in neighbor cells. However, such spikes might occasionally cause ar tificially large delays between synchronized bursts. The bursts then re-excite the thalamic reticular neurons (though reciprocal connections). Two of these bursts are shown at a faster time scale, revealing their intrinsic characteristics. Pure tones and noise bursts were used as acoustic stimuli. At the circled bar, a unit activity (459 spikes in 81 bursts) was recorded and analyzed. These examples are from corpora and from sources on the web.
