BACKGROUND With the expanded use of the radial artery as a bypass conduit in patients undergoing coronary artery bypass grafting, an endoscopic radial artery harvesting method was used to improve esthetics and patient acceptance, and possibly, to decrease hand neurologic complications. METHODS After informed consent and confirmation of adequate ulnar collateral blood flow, 300 consecutive pat...

The main contribution of the present paper is to train efficient neural networks for seismic design of double layer grids subject to multiple-earthquake loading. As the seismic analysis and design of such large scale structures require high computational efforts, employing neural network techniques substantially decreases the computational burden. Square-on-square double layer grids with the va...

A large diameter (up to 73.8 cm), high-density helicon plasma with short axial length (≤ 81 cm) has been successfully produced using a flat spiral antenna. The electron plasma density can reach up to ∼ 10 cm−3 with the input radio frequency (rf) power of < 4 kW for various axial lengths, and the density scaling as a function of the axial length is in good agreement with expectations. The strong...

Sarcomere length was measured in flexor carpi ulnaris (FCU) muscles from patients with severely spastic wrist flexion contractures (n = 6), as well as from patients with radial nerve injury and a normally innervated FCU (n = 12). Spastic FCU muscles had extremely long sarcomere lengths with the wrist fully flexed (3.48 +/- 0.44 microm) compared to the FCU muscles of patients with radial nerve i...

High conversion efficiency ~0.1%! into second harmonic light generated in the interaction of a short-pulse intense laser with underdense plasma has been observed. In this experiment the plasma is created by optical field ionization of hydrogen or helium gas. Second harmonic spectra observed in the forward direction show Stokes and anti-Stokes satellites. This is due to the interaction of the se...

In this paper we provide new simple closed-form solutions to two minimal absolute pose problems for the case of known vertical direction. In the first problem we estimate absolute pose of a calibrated camera from two 2D-3D correspondences and a given vertical direction. In the second problem we assume camera with unknown focal length and radial distortion and estimate its pose together with the...

Xylem maturation depends on cambial age rather than diameter growth in Shorea macrophylla by the model selections for radial variations cell length, wood fiber traits, and basic density. Radial anatomical characteristics properties were investigated 23-year-old (engkabang) trees planted Sarawak, Malaysia. The effects of rates manner xylem determined based selected mixed-effects models. best mod...

By solving the Bogoliubov--de Gennes Hamiltonian, electron-hole coherence within a partially proximitized $n$-doped semiconductor shell of core-shell nanowire heterostructure is investigated numerically and compared with Andreev reflection interpretation proximity induced superconductivity. Partial proximitization considered to quantify effects reduced length. Three cases partial are explored: ...
