Differential Dual-Hop Relaying under User Mobility [PDF]
IET Communications, 2014 This paper studies dual-hop amplify-and-forward relaying system employing differential encoding and decoding over time-varying Rayleigh fading channels. First, the convectional "two-symbol" differential detection (CDD) is theoretically analysed in terms ...

Dual-polarized Dual-band Mobile 5G Antenna Array [PDF]
Proceedings of the 15th International Joint Conference on e-Business and Telecommunications, 2018 In this paper, a dual-band dual-polarized phased antenna array for 5G mobile terminals is proposed. The array has a bandwidth of 3.6 GHz and two resonances at 30.5 and 32.8 GHz. The array has a clearance of 2.85 mm and fed with two ports in simulation to excite the notch and dipole parts of the proposed antenna structure.

Dual Mobility Cups as the Routine Choice in Total Hip Arthroplasty
Medicina, 2022 Background and Objectives: Total hip arthroplasty (THA) is considered the most successful surgical procedure in orthopedics. However, dislocation remains the main indication for surgical revision.

Age-related decrements in dual-task performance: Comparison of different mobility and cognitive tasks. A cross sectional study. [PDF]
PLoS ONE, 2017 This cross-sectional study investigated the age-related differences in dual-task performance both in mobility and cognitive tasks and the additive dual-task costs in a sample of older, middle-aged and young adults. 74 older adults (M = 72.63±5.57 years),

Inertial Tracking System for Monitoring Dual Mobility Hip Implants In Vitro
Sensors, 2023 Dual mobility (DM) implants are being increasingly used for total hip arthroplasties due to the additional range of motion and joint stability they afford over more traditional implant types.

Dual Polarity Ion Confinement and Mobility Separations [PDF]
Journal of the American Society for Mass Spectrometry, 2019 Here, we present simulations and describe the initial implementation of a device capable of performing simultaneous ion mobility (IM) separations of positive and negative ions based upon the structures for lossless ion manipulations (SLIM). To achieve dual polarity ion confinement, the DC fields used for lateral confinement in previous SLIM were ...
