Taper-Walled Linearly Tapered Slot Antenna
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2011 Direct coupling among antenna elements is one of the critical problems of array antennas in near-field imaging systems. To mitigate the coupling, we propose taper-walled linearly tapered slot antenna (taper-walled LTSA) to be used in our adaptive ground penetrating radar (GPR) system for visualization of plastic landmines.

A spot-size transformer for fiber-chip coupling in sensor applications at 633 nm in silicon oxynitride [PDF]
, 1995 A mode-size adapter was designed, fabricated in SiON/SiO2 and tested. It consists of a laterally tapered SiON waveguide having a step-wise decrease in thickness towards the taper point which may have up to 0.5 ¿m residual ...

5-Gbit/s BER performance on an all fiber-optic add/drop device based on a taper-resonator-taper structure [PDF]
, 2000 We present an all fiber-optic add/drop device based on a taper-resonator-taper structure with improved characteristics. Several gigahertz bandwidths are observed using microspheres having diameters ranging from 30 to 50 μm.

Ceramic Heads Decrease Metal Release Caused by Head-taper Fretting and Corrosion
Clinical Orthopaedics and Related Research, 2016 BackgroundMetal release resulting from taper fretting and corrosion is a clinical concern, because wear and corrosion products may stimulate adverse local tissue reactions. Unimodular hip arthroplasties have a conical taper between the femoral head (head

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an immune‐mediated neuropathy featuring progressive weakness, sensory deficits, and areflexia. While corticosteroids, intravenous immunoglobulin, and plasmapheresis are effective first‐line immunotherapies, a subset of patients remains treatment‐refractory.

Characterization of the Plasma Shape of the TIG Welding Arc [PDF]
, 2006 Tungsten electrodes were prepared to analyse the plasma geometry at TIG welding. The investigated electrodes were La02, Th02 alloyed. Tip flatted electrodes were grinded as well. The shape of plasma were analysed for 36 different electrodes.

Nanobeam photonic crystal cavity quantum dot laser [PDF]
, 2010 The lasing behavior of one dimensional GaAs nanobeam cavities with embedded InAs quantum dots is studied at room temperature. Lasing is observed throughout the quantum dot PL spectrum, and the wavelength dependence of the threshold is calculated.

A 73‐Year‐Old Man With Several Years of Difficulty Climbing Stairs and Frequent Tripping
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT A 73‐year‐old man presented with progressive weakness and atrophy predominantly affecting the distal finger flexors and quadriceps muscles. Electrophysiological studies demonstrated mixed myogenic and neurogenic features. Muscle MRI showed inflammatory changes, and muscle biopsy revealed granulomatous myositis with histologic features ...

Asymmetric fiber taper for narrow linewidth comb filter [PDF]
, 2016 The employment of asymmetric optical fiber taper as a means for producing narrow linewidth comb filter is proposed and demonstrated. Fiber taper with different values set for the up-taper and down-taper transition regions was used to produce narrow ...
