BACKGROUND Residential mobility is common in families with young children; however, its impact on the social development of children is unclear. We examined associations between the number, timing and type of house moves in childhood and child behaviour problems using data from an ongoing longitudinal study. METHODS Complete data on residential mobility and child behaviour was available for 4...

We need to solve various mobility/traffic problems in one-dimensional (1-D), two-dimensional (2-D), and threedimensional (3-D) micro or picocell environments to efficiently plan future personal communications services (PCS’s). However, mobility/traffic problems have thus far primarily been studied in 1-D and 2-D cell structures. In this paper, we extend the previous mobility modeling from 1-D o...

The high-level contribution of this paper is to establish benchmarks for the minimum hop count per source-receiver path and the minimum number of edges per tree for multicast routing in mobile ad hoc networks (MANETs) under different mobility models. In this pursuit, we explore the tradeoffs between these two routing strategies with respect to hop count, number of edges and lifetime per multica...

The acquisition of accurate channel state information at the transmitter (CSIT) is a difficult task in multiple-input multiple-output (MIMO) systems. Partial CSIT is a more realistic assumption, especially for high-mobility mobile users (MUs) whose channel varies very rapidly. In this letter, we propose a MIMO two-way relaying (MTWR) scheme, in which the communication between the BS and a high-...

Management of mobility especially balancing the load of handoff for wireless networks is an essential parameter for wireless network design and traffic study. In this paper, we present analytical mobility management in high speed wireless mobile networks focusing on factors such as the number of channel slots and offered load. We demonstrate the performance of handoffs with mobility considerati...

Hole mobility and flicker noise characteristics of uniaxially strained (110)/〈110〉 Si0.75Ge0.25 pFINFETs (SSGOI0.25) are investigated in this letter. Equivalent gate referred flicker noise in SSGOI0.25 is dominated by correlated number and mobility fluctuation in the low-bias regime and Hooge mobility fluctuation in the high-bias regime. The extracted Hooge parameter in SSGOI0.25 and in Si pFIN...

Cellular networks have been hierarchical so that mobility management have primarily been deployed in a centralized architecture. More flattened network architecture for the mobile Internet is anticipated to meet the needs of rapidly increasing traffic from the mobile users and to reduce cost in the core network. Distributing the mobility management functions as opposed to centralizing them at t...

-Mobile Ad Hoc Networks (MANET) performance is affected by a number of factors, eg. speed, node density. In this paper we will focus on the effect of constrained mobility on the performance of the MANET protocol. Experiments were carried out to measure the performance of MANET protocols in two mobility patterns: random waypoint and Metropolitan Grid(M-Grid). The latter reflects the mobility pat...

We developed a label-free method for a determination of the number of biomolecules attached to individual cells by measuring the electrophoretic mobility of the cells in a microchannel. The surface of a biological cell, which is dispersed in aqueous solution, is normally electrically charged and the charge quantity at the cell's surface is slightly changed once antibody molecules are attached t...
