Knowledge of the occurrence and mobility of carbonate-rich melts in the Earth's mantle is important for understanding the deep carbon cycle and related geochemical and geophysical processes. However, our understanding of the mobility of carbonate-rich melts remains poor. Here we report viscosities of carbonate melts up to 6.2 GPa using a newly developed technique of ultrafast synchrotron X-ray ...

In the last several years the MANET routing protocols and mobility model combinations have been studied widely. These studies have used different MANET parameters for performance evaluation due to which the uniformity for the sake of comparison among the research works has been missing. This work provides a comprehensive study using wide range of MANET parameters, and draws conclusions for the ...

A corrected equation for the concentrations in the drift tube of a proton transfer reaction-mass spectrometer (PTR-MS) is presented which ccounts for the different mobility of primary ions and protonated analyte volatile organic compounds (VOCs). As a consequence, the calculation f VOC concentrations from the measured count rates requires as well a correction factor, equalling the ratio of (i) ...

We report the fabrication of ionic liquid (IL)-gated field-effect transistors (FETs) consisting of bilayer and few-layer MoS2. Our transport measurements indicate that the electron mobility μ ≈ 60 cm(2) V(-1) s(-1) at 250 K in IL-gated devices exceeds significantly that of comparable back-gated devices. IL-FETs display a mobility increase from ≈ 100 cm(2) V(-1) s(-1) at 180 K to ≈ 220 cm(2) V(-...

BACKGROUND Little is known about older patient's mobility soon after discharge home from an acute hospitalization. We examined daily postdischarge mobility levels as marker of overall health and response to in-hospital treatment in older medicine patients. METHODS One hundred and eleven ambulatory men and women aged 65 years and older hospitalized with an acute medical illness and discharged ...

Motivated by emerging applications, we consider sensor networks where the sensors themselves (not just the sinks) are mobile. Furthermore, we focus on mobility scenarios characterized by heterogeneous, highly changing mobility roles in the network. To capture these high dynamics of diverse sensory motion we propose a novel network parameter, the mobility level, which, although simple and local,...

[1] In this study we incorporate the existing concept of fractional mobility into a stochastic framework for modeling the partial transport of mixed-size sediment. The model predicts the fractional transport rates with parameters such as the long-run moving probability, mean particle velocity, and fractional mobility, all varying with the dimensionless effective shear stress. Movement of bed lo...

Objective: To compare the diaphragmatic mobility of healthy subjects during incentive spirometry with a volumeoriented device, during incentive spirometry with a flow-oriented device, and during diaphragmatic breathing. To compare men and women in terms of diaphragmatic mobility during these three types of breathing exercises. Methods: We evaluated the pulmonary function and diaphragmatic mobil...

Lateral diffusion of cell membrane constituents is a prerequisite for many biological functions. However, the diffusivity (or mobility) of a membrane-bound species can be influenced by many factors. To provide a better understanding of how the conformation and location of a membrane-bound biological molecule affect its mobility, herein we study the diffusion properties of a pH low insertion pep...

Opportunistic Routing (OR) is an effective and enhanced routing scheme for wireless multihop environment. OR is an approach that selects a certain number of best forwarders (candidates) at each hop by taking the advantage of the broadcast nature of the wireless medium to reach the destination. When a set of candidates receive the packet, they coordinate with each other to figure out which one h...
