The swinging eyelid procedure is a versatile technique to approach orbital and periorbital surgical fields with less visible scar. Although mainly used in orbital surgeries, this procedure can also be used to expose the zygomatic arch and periorbital areas. The swinging eyelid procedure, therefore, enables appropriate reduction of zygomaticomalar fracture under direct visualization. We used thi...

Ciliates are well known for their unusual tricks of nuclear remodeling. A roulette-like method for mating type choice in Tetrahymena adds an interesting new twist to their repertoire.

Measurements on the swing of a baseball bat are analyzed to extract the basic mechanics of the swing. The force acting on the bat is determined from the velocity of the center of mass, and the angular velocity of the bat provides additional information on the couple exerted by the two hands. The motion of the bat was calculated for other force-couple combinations to determine their effects on t...

We examine how perturbed shear flows evolve in two-dimensional, incompressible, inviscid hydrodynamical fluids, with the ultimate goal of understanding the dynamics of accretion disks, as well as other astrophysical shear flows. To linear order, vorticity waves are swung around by the background shear, and their velocities are amplified transiently before decaying. It has been speculated that s...
