both the broadcast and the pointer based schemes for Prole I over a wide range of call/mobility ratios. The pointer based scheme performs better than the list based scheme only for a high call/mobility ratio in Prole II. Pointer based scheme incurs a penalty for informing the base stations of the new address for each move. The lower the mobility, the lower the cost of pointers. Thus under high ...

The variation of the energy spectrum of n±i±p±i crystals under excitation was examined and the influence of the reduction of the screening length on the ratio between the coefficient of diffusion and the mobility of the current carriers was established. It is shown that the filling of subband states by carriers results in an anomalous behaviour of the diffusivity±mobility ratio. The effect occu...

objectives: it is important to recognize any risk factors for the development of injuries in the athletic population. the aim of this study was to investigate the association between joint hyper mobility and low back pain in iranian hyper mobile and non-hyper mobile athletes. methods: 50 athletic patients with low back pain (age=23.20±12.79 years) and 51 healthy athletes (age=24.28±13.70) from ...

PURPOSE to examine the combined effect of cohabitation status and social participation, respectively, and socioeconomic position on onset of mobility limitations in a prospective study among older Danes. DESIGN AND METHODS logistic regression analyses with combined exposure variables were performed in a study population of 2,839 older men and women from the Danish Intervention Study on Preven...

Intergenerational Occupational Mobility in India In this paper, we examine the intergenerational occupational mobility in India among men born during 1945-85. Following Long and Ferrie (2013, American Economic Review), we not only distinguish between prevalence and association, but also use the Altham Statistics – which involves comparison of all possible odds ratios, for example, the odds that...

In order to combine advantages of ZnO thin film transistors (TFTs) with a high on-off ratio and graphene TFTs with extremely high carrier mobility, we present a facile methodology for fabricating ZnO thin film/graphene hybrid two-dimensional TFTs. Hybrid TFTs exhibited ambipolar behavior, an outstanding electron mobility of 329.7 ± 16.9 cm(2)/V·s, and a high on-off ratio of 10(5). The ambipolar...

BACKGROUND Patients with hip fracture frequently have sarcopenia and are at great risk of loss of mobility. We have investigated if sarcopenia predicts change in mobility after hip fracture. METHODS This is a prospective, multicenter observational study with one-year follow-up. Patients with hip fracture who were community-living and capable of walking before the fracture were included at thr...

Objective. Independent mobility refers to the freedom that children have to move around their neighborhood without adult supervision. It is related to their physical activity and health. We examined the intrapersonal, family, and neighborhood correlates of independent mobility within children. Methods. 497 American parents of 6.9-11.9 year olds completed a survey (November, 2014) that assessed ...

Based on application requirements, nodes are static or mobile in Wireless Sensor Networks (WSNs). Mobility poses challenges in protocol design, especially at the link layer requiring mobility adaptation algorithms to localize mobile nodes and predict link quality to be established with them. This study implements XMAC and Berkeley Media Access Control (BMAC) routing protocols to evaluate perfor...
