Novel laser controlled variable matter wave beamsplitter.

We demonstrate a novel variable beam splitter using a tripod-linkage of atomic states, the physics of which is based on the laser control of the non-adiabatic coupling between two degenerate dark states. This coupling and the splitting ratio is determined by the time delay of the interaction induced by two of the laser beams.

A rare uterine tumor presenting as deep venous thrombosis.

A 63-year-old woman with a rare pelvic tumor is presented as an example of an unusual clinical complaint for this neoplasm. The patient's original complaint was lower leg pain with swelling. Deep venous thrombosis was identified and ancillary studies confirmed the presence of a pelvic mass.

Vena cava replacement with a peritoneum-lined vascular graft.

The use of the peritoneum as a venous conduit was analyzed because of the inherent fibrinolytic properties of the mesothelium. A canine model in which the infrarenal inferior vena cava was replaced with interposition grafts (2 cm) of either a peritoneal tube, polytetrafluoroethylene (PTFE), or PTFE lined with peritoneum (lined graft) was studied. Venograms were performed 1 and 6 weeks after graft implantation for the percent area reduction of the lumen.

Unnatural deaths in nursing home patients.

Nursing home residents comprise a large and rapidly growing segment of the national population. Despite this fact, the majority of deaths occurring in nursing homes are not investigated because of the significant medical illnesses suffered by most residents. Herein, we report a series of unnatural deaths in nursing home residents, including two homicides and seven accidental deaths.
