Phacoemulsification with a bevel-down phaco tip: phaco-drill

We present a technique for in situ lens nucleus emulsification using low phaco power and high vacuum, a continuous curvilinear capsulorhexis, and hydrodelineation. Emulsification is done with the phaco tip slanted down 30 or 45 degrees. Cutting and aspiration do not cause an undesirable energy loss. This technique can be combined with the nuclear chopping or divide and conquer methods because of its ability to drill and hold the nucleus. Posterior capsular rupture is prevented because the separated epinucleus acts as a barrier between the nucleus and the cortex. The low power used minimizes the energy transfer to the corneal endothelium. This technique is particularly useful in eyes with brunescent cataract.

Principles for radiation of time-harmonic elementary current in magnetized electron plasma half-space

The radiation emitted by a time-harmonic elementary current in magnetized electron plasma half-space, bounded by an ideal electric plane, is investigated using an exact formulation. It is found that: conventional image principle holds for vertical magnetization case; while for parallel magnetization case, coupled image principle seems to be valid.     

Loss performance of tagged and normal ATM cells at a partiallyshared buffer

The loss performance of tagged and normal ATM cells at a first-in-first-out (FIFO) buffer is studied. The authors show that if a partial buffer sharing mechanism is adopted the loss probability of normal cells can be firmly guaranteed, regardless of the traffic intensity of tagged cells
