Experimental Gait Analysis to Study Stress Distribution of the Human Foot.

Researchers and clinicians are increasingly using plantar pressure and force measurement system to evaluate foot functions. This research evaluates the quality and reliability of a Tekscan HR mat to study the plantar pressures and forces acting during walking, running, jumping, and standing of healthy subjects. The following regions of the foot were investigated: heel, mid foot, metatarsophalangeal joint, hallux, and the toes.

Time-resolved study of laser initiated shock wave propagation in superfluid He.

Intense shock waves in superfluid He between 1.7 and 2.1 K are generated by rapidly expanding confined plasma from laser ablation of a metal target immersed in the liquid.

Laser-Assisted Detection of Metal Nanoparticles in Liquid He-II.

The formation of gas bubbles surrounding laser heated copper nanoparticles in superfluid helium at 1.7 K is observed. Because of the effective light capture by these plasmonic particles and the subsequent heat transfer into the liquid, such bubbles grow within 3 μs to tens of micrometers in size.

Current trends in the diagnosis and treatment of pyloric stenosis.

Aim: We hypothesized that recent trends towards earlier diagnosis of hypertrophic pyloric stenosis continued throughout the early part of the 21st century.

Methods: We reviewed the medical records of patients with HPS at a single institution during two periods: 1/03-12/05 and 4/09-7/13.

Results: A total of 433 patients with hypertrophic pyloric stenosis who underwent pyloromyotomy were included (modern cohort = 259; historic = 174).
