Interactions between space-based and feature-based attention.

Although early research suggested that attention to nonspatial features (i.e., red) was confined to stimuli appearing at an attended spatial location, more recent research has emphasized the global nature of feature-based attention.

Fibula free flap with endosseous implants for reconstructing a resected mandible in bisphosphonate osteonecrosis.

Purpose: Bisphosphonates are a class of drugs with several uses. Primarily, they are used to treat bone metastases, multiple myeloma, Paget's disease, and osteoporosis. However, the use of bisphosphonates can lead to osteonecrosis of the jaws.

Slow to superluminal light waves in thin 3D photonic crystals.

Phase measurements on self-assembled three-dimensional photonic crystals show that the group velocity of light can flip from small positive (slow) to negative (superluminal) values in samples of a few mum size. This phenomenon takes place in a narrow spectral range around the second-order stop band and follows from coupling to weakly dispersive photonic bands associated with multiple Bragg diffraction. The observations are well accounted for by theoretical calculations of the phase delay and of photonic states in the finite-sized systems.

The submental island flap in head and neck reconstruction.

The authors describe their experience with the submental island flap for the primary correction of head and neck deformities following oncologic surgery, over the past 5 years. The use of this flap is reported in 12 patients, with a mean age of 67 years, requiring facial or intraoral reconstruction. A brief review of the key points and some refinements in the operative technique are discussed.
