Failure characteristics of all polyethylene cemented glenoid implants in total shoulder arthroplasty [PDF]
, 2010 Total shoulder arthroplasty (TSA) still suffers today from mid-term and long-term complications such as glenoid implant loosening, wear, humeral head subluxation/dislocation and implant fracture. Unlike the hip and knee joint replacements, the artificial

Tectonic settings influence the geochemical and microbial diversity of Peru hot springs
Communications Earth & Environment, 2023 Tectonic processes control hot spring temperature and geochemistry, yet how this in turn shapes microbial community composition is poorly understood. Here, we present geochemical and 16 S rRNA gene sequencing data from 14 hot springs from contrasting ...

Spatiotemporal Characterization of Supercontinuum Extending from the Visible to the Mid-Infrared in Multimode Graded-Index Optical Fiber [PDF]
, 2016 We experimentally demonstrate that pumping a graded-index multimode fiber with sub-ns pulses from a microchip Nd:YAG laser leads to spectrally flat supercontinuum generation with a uniform bell-shaped spatial beam profile extending from the visible to ...

Polylidar3D-Fast Polygon Extraction from 3D Data
Sensors, 2020 Flat surfaces captured by 3D point clouds are often used for localization, mapping, and modeling. Dense point cloud processing has high computation and memory costs making low-dimensional representations of flat surfaces such as polygons desirable.

Semi-infinite Throat as the End-state Geometry of two-dimensional Black Hole Evaporation [PDF]
, 1995 We study a modified two-dimensional dilaton gravity theory which is exactly solvable in the semiclassical approximation including back-reaction. The vacuum solutions of this modified theory are asymptotically flat static space-times.

Surgical Treatment of Flat Back Syndrome With Anterior Hyperlordotic Cages [PDF]
Operative Neurosurgery, 2019 Abstract BACKGROUND Traditional correction for flat back syndrome is performed with a posterior-based surgery or combined approaches in revision cases. OBJECTIVE To evaluate outcome from anterior surgery with the use of hyperlordotic cages (HLCs) in patients with flat back
