Dear Editor These ultrasound images (Fig. 1. Images A–D) convey an enlarged posterior interosseous nerve (PIN) with interruption of the PIN course by dislodgement of the distal of two Mitek anchors inserted 5 years previously for a biceps tendon rupture raising suspicion of PIN transection at the level of the distal biceps anchor. Surgical exploration confirmed complete PIN laceration with the ...

The hydrophilicity of vertically aligned metal nanorods with sharp nanotips were investigated experimentally. Ruthenium and platinum nanorod arrays were deposited on flat silicon substrates using oblique angle sputter deposition. We show that the effects of nanotips on nanorods should be considered in the "hemiwicking" model for hydrophilic metallic samples. With the influence of nanotips, we s...

Ultrafast electron pulses can be produced from sharp metallic tips illuminated by femtosecond near infrared laser pulses. Use of an array of metallic nanotips for high charge bunch generation and accelerator applications is also feasible but the small fraction of the emitter tip area limits the quantum efficiency. We therefore propose a submicron-pitch, high-density nanotip array device with a ...

Intense multiphoton electron emission is observed from sharp (∼ 20 nm radius) metallic tips illuminated with weak 100 pJ, 7-fs light pulses. Local field enhancement, evidenced by concurrent nonlinear light generation, confines the emission to the tip apex. Electrons are emitted from a highly excited nonequilibrium carrier distribution, resulting in a marked change of the absolute electron flux ...

The insulator-metal transition was observed experimentally in nickel monoxide (NiO) at very high pressures of ~240 GPa. The sample resistance becomes measurable at about 130 GPa and decreases substantially with the pressure increase to ~240 GPa. A sharp drop in resistance by about 3 orders of magnitude has been observed at ~240 GPa with a concomitant change of the resistance type from semicondu...

Intra-articular migration is a known complication of poorly placed metallic suture anchors in rotator cuff repair and labral reconstruction. We report a case of intra-articular migration of a metallic suture anchor seven years after open labral reconstruction. Despite the fact that the patient remained asymptomatic for seven years, presence of an extra-osseous anchor was already noted postopera...

Longitudinal fields created in strongly focused laser beams are investigated by near-field optical microscopy. Sharp metallic and dielectric tips are raster scanned through the focus of these modes. It is found that regardless of the tip material, the signal scattered by the tip is a measure for the strength of the local longitudinal field. A surprising contrast reversal is observed between the...

Intense multiphoton electron emission is observed from sharp (approximately 20 nm radius) metallic tips illuminated with weak 100-pJ, 7-fs light pulses. Local field enhancement, evidenced by concurrent nonlinear light generation, confines the emission to the tip apex. Electrons are emitted from a highly excited nonequilibrium carrier distribution, resulting in a marked change of the absolute el...
