The modern state of femoral, acetabular, and global offsets in total hip arthroplasty: a narrative review

open access: yesEFORT Open Reviews, 2023
• Offsets in the frontal plane are important for hip function. • Research on total hip arthroplasty (THA) surgery agrees that increasing femoral offset up to 5 mm could improve functional outcome measures.

Effect of Torsion Stress on the Offset and Sensitivity of Diagonal and Off-Diagonal GMI in Amorphous Wires

open access: yesSensors, 2018
In this paper, the torsional stress effect on Giant Magneto-Impedance (GMI) was studied in Co-rich amorphous wires. The study, which was conducted in the context of the development of a current clamp based on GMI, considered torsion as a parameter of the

Research and Engineering Application of Modular Bridge-along Cable OFFSET

open access: yesZhejiang dianli, 2022
The cable expansion compensation device, better known as OFFSET, is required as an expansion joint on the bridge. At present, the technology has its limitations and thus cannot meet the demand of narrow spaces and expansion joints of different sizes ...

Joint Algorithm for Multi-Hop Localization and Time Synchronization in Underwater Sensors Networks Using Single Anchor

open access: yesIEEE Access, 2021
In this study, an effort to synchronize and localize the underwater sensors simultaneously in a multi-hop environment is considered. Underwater Sensor Networks (UWSNs) has limited range and connectivity due to propagation delay and limited bandwidth.

Investigating the Interhemisphere 14C Offset in the 1st Millennium AD and Assessment of Laboratory Bias and Calibration Errors [PDF]

open access: yes, 2009
Past measurements of the radiocarbon interhemispheric offset have been restricted to relatively young samples because of a lack of older dendrochronologically secure Southern Hemisphere tree-ring chronologies. The Southern Hemisphere calibration data set

Extension of the HEMRM—Full Harmonization of the Electricity Supply System

open access: yesElectricity
The current formal common denominator of the electricity supply system in Europe has been the Harmonized Electricity Market Role Model (HEMRM) set up by ENTSO-E, ebIX, and EFET at the turn of the millennium; it introduced the concept of de-coupling and ...

Topological Offsets

open access: yesACM Transactions on Graphics
We introduce Topological Offsets , a novel approach to generate manifold and self-intersection-free offset surfaces that are topologically equivalent to an offset infinitesimally close to the surface.
