We investigate the dynamical origin for the occurrence of asynchronous hyperchaos and chaos via blowout bifurcations in coupled chaotic systems. An asynchronous hyperchaotic or chaotic attractor with a positive or negative second Lyapunov exponent appears through a blowout bifurcation. It is found that the sign of the second Lyapunov exponent of the newly born asynchronous attractor, exhibiting...

Orbital injuries are often missed out when they occur concomitantly with other facial bone fractures. Clinical examination and plain radiographic findings alone may prove inadequate in the detection of orbital floor fractures. Refined imaging techniques like CT scans and MRI are immensely helpful in the diagnosis of orbital blowout fractures. A case of 'impure' orbital blowout fracture which we...

The self-guiding of relativistically intense but ultrashort laser pulses has been experimentally investigated as a function of laser power, plasma density, and plasma length in the blowout regime. The extent of self-guiding, observed by imaging the plasma exit, is shown to be limited by nonlinear pump depletion with observed self-guiding of over tens of Rayleigh lengths. Spectrally resolved ima...

PURPOSE To investigate the surgical timing postinjury in regard to ocular motility in patients with orbital-floor blowout fractures. METHODS This study involved 197 eyes (92 right eyes and 105 left eyes) of 197 patients (154 males and 43 females, mean age: 29.0 years, range: 7-85 years) with pure orbital blowout fractures. All patients underwent surgical repair within 30 days postinjury and w...

Shell must cease drilling well before the water freezes over lest a late-season blowout cause oil to accumulate under the ice through the winter.

The Whitehead Minimization problem is a problem of finding elements of the minimal length in the automorphic orbit of a given element of a free group. The classical algorithm of Whitehead that solves the problem depends exponentially on the group rank. Moreover, it can be easily shown that exponential blowout occurs when a word of minimal length has been reached and, therefore, is inevitable ex...

It is shown that bright cluster dwarf ellipticals follow a relation between metallicity and apparent flattening. Rounder dwarfs tend to be more metal-rich. The evidence is based on colour as well as spectroscopic line-strength data from the literature. The large scatter of dEs around the mean metallicity-luminosity relation, usually ascribed to large observational errors, turns out to be an ell...
