Dual mobility cups are a new valuable option in treating and preventing dislocation in primary and revision THAs. In contrast with all alternative treatments such as f.e constrained liners, they do not compromise the implant durability and the clinical outcomes [1].

Sex and Mobility in the Dual Economy
Work and Occupations, 1986Recent work using a dual-economy approach to labor markets has documented heterogeneities in descriptive profiles of workers and returns to human capital by core-periphery sector of the economy. However, an important need that has gone relatively uninformed is an understanding of movement across sectors of the economy as a dimension of individual ...

Indexing mobile objects using dual transformations
The VLDB Journal, 2005With the recent advances in wireless networks, embedded systems, and GPS technology, databases that manage the location of moving objects have received increased interest. In this paper, we present indexing techniques for moving object databases. In particular, we propose methods to index moving objects in order to efficiently answer range queries ...

All dual mobility cups are not the same
International Orthopaedics, 2017Although the natural history of dual mobility has been exclusively borne for 20 years by a single company (due to industrial ownership), the concept has undeniably been very widely popularised with nearly 40 cups on the French market which should be regarded as a weight bearing surface, both broadly and in their own right.

A Retrieval Analysis of Impingement in Dual-Mobility Liners
The Journal of Arthroplasty, 2018Implant-related impingement is likely a major causative factor of total hip arthroplasty (THA) instability. Dual-mobility (DM) cups can theoretically improve stability in THA, but impingement rates with DM cups are not well studied. We examined retrieved DM THA liners to determine if less evidence existed for prosthetic impingement between the neck and

Dual Transmission Architecture for Mobile Multicasting
2003With the popularity of mobile devices, Internet service providers are interested in supporting mobile applications. Mobile IP standards have been developed without considering multicast services. This paper explores the issues of multicasting for mobile hosts and problems of previous approaches, and proposes dual-transmission architecture for mobile ...

Dual wideband radiating element for mobile handsets
Microwave and Optical Technology Letters, 2003AbstractA lightweight, low‐cost antenna suitable for personal communication handsets is proposed. This antenna consists of two stacked quarter‐wavelength elements short‐circuited along the same plane. A slot was embedding in each patch to allow the achievement of two widebands, including GSM and DCS/PCS/UMTS system applications.

Dual-anonymous reward distribution for mobile crowdsensing
2017 IEEE International Conference on Communications (ICC), 2017Mobile crowdsensing enables individuals to collect data from social events and phenomena for performing tasks released by customers using their mobile devices. It removes the necessity of sensors deployment and hence supports large-scale sensing applications efficiently.

Dual Mobility for Chronic Instability
Seminars in Arthroplasty, 2011A dual mobility cup consists of a large, fixed, porous coated acetabular component and a bipolar femoral component (a "tripolar" implant). The cup was developed to reduce the incidence of dislocation in patients at risk of instability who required primary or revision total hip replacement.

Once upon a time.... Dual mobility: history
International Orthopaedics, 2016Since 1962, the low friction arthroplasty developed by Sir John Charnley has given us very good long terms results at more than 40 years follow up, but dislocation remains a major complication. The dislocation rate is a permanent risk during the life of the patient and the prosthesis, defined by J. Caton and D.
