Alfvén waves have been proposed as an important mechanism for the heating of the Sun's outer atmosphere and the acceleration of solar wind, but they are generally believed to have no significant impact on the Earth's upper atmosphere under quiet geomagnetic conditions due to their highly fluctuating nature of interplanetary magnetic field (i.e., intermittent southward magnetic field component)....

A 67-year-old myopic man presented to the Ophthalmology Department of a teaching hospital in the mountainous state of Sikkim with complaints of red eye, ocular discomfort, and sensation of something moving in his right eye that led to occasional visual blurring from the previous four days. His symptoms started after washing his face in a stream. Clinical diagnosis was a leech in the limbus of t...

Consider a source using a high speed data link to transmit packets to a nite capacity downstream buuer. For bursty sources using high speed links, an entire burst might be transmitted to the downstream buuer before any feedback would be received. Regulating the packet transmission process to minimize packet blocking at the downstream link is formulated as an open loop stochastic scheduling prob...

The cause is unknown but hereditary factors may play a role. Incontinence may be continuous (Fig. 4, page 11) or intermittent and even when both ureters are ectopic (bilateral ectopic ureter,), the dog can usually still pass a normal stream of urine, despite the copious leakage at other times. Diagnosis is by contrast radiography (special x-ray studies discussed in more detail in the section Ho...

This work presents results from large-eddy/Reynolds-averaged Navier–Stokes (LES/RANS) simulations of the well-known Burrows–Kurkov supersonic reacting wall-jet experiment. Generally good agreement with experimental mole fraction, stagnation temperature, and Pitot pressure profiles is obtained for non-reactive mixing of the hydrogen jet with a non-vitiated air stream. A lifted flame, stabilized ...

Detecting the failure of a data stream is relatively easy when the stream is continually full of data. The transfer of large amounts of data allows for the simple detection of interference, whether accidental or malicious. However, during interference, data transmission can become irregular, rather than smooth. When the traffic is intermittent, it is harder to detect when failure has occurred a...

We consider a process on a compact two-dimensional surface which consists of the fast motion along the stream lines of an incompressible periodic vector field perturbed by white noise. It gives rise to a process on the graph naturally associated to the structure of the stream lines of the unperturbed flow. It has been shown by Freidlin and Wentzell that if the unperturbed motion is periodic for...

An array of seven inverted echo sounders was moored along and across the Kuroshio in the East China Sea for more than one year. The data from this array show evidence of energetic meanders with periods of 7, 11, and 16 days. The respective phase velocities of these meanders are 28, 20, and 17 km day21 downstream. The 7and 16-day waves are intermittent, but the 11-day waves are present throughou...

We used an intermittent stimulus presentation to investigate event-related potential (ERP) components associated with perceptual reversals during binocular rivalry. The combination of spatiotemporal ERP analysis with source imaging and statistical parametric mapping of the concomitant source differences yielded differences in three time windows: reversals showed increased activity in early visu...
