EXPLORING SIMILARITIES AND VARIATIONS OF HUMAN MOBILITY PATTERNS IN THE CITY OF LONDON
time-series cluster analysis smart card data human mobility spatiotemporal patterns
2018/11/9
The availability of new spatial data represents an unprecedented opportunity to better understand and plan cities. In particular, extensive data sets of human mobility data supply new information that...

New Details Temperature Mobility Earth’s Lower Crust Rocky Mountains
2018/2/1
Everything on the surface of the Earth rests on massive tectonic plates that resemble a jelly sandwich, with two rigid pieces — the upper crust and the upper mantle — enclosing a gooey middle layer of...
Writing and Erasing Barriers to Lateral Mobility Into Fluid Phospholipid Bilayers
nematics dielectric anisotropy density viscosity
2016/5/23
We describe a method for making and erasing barriers to the lateral diffusion of membrane components in fluid lipid bilayers supported on glass substrates. When a bilayer is mechanically partitioned b...
Trace elements mobility in soils from the hydrothermal area of Nisyros (Greece)

2015/8/18
Nisyros Island, Greece, is a stratovolcano known for its intense hydrothermal activity. On June 2013, during a multidisciplinary field campaign, soil samples were collected in the caldera area to dete...

All soil samples were air dried, thoroughly mixed and split into subsamples for analysis. Particular care was taken using a Riffle-type sample splitter to ensure that representative subsamples were ob...
Deciphering boulder mobility and erosion from cosmogenic nuclide exposure dating
Deciphering boulder mobility erosion from cosmogenic nuclide exposure dating
2014/4/8
Large boulders are prominent features in many geomorphic systems and are frequently targeted for cosmogenic exposure dating. Presently, there are little data or theory predicting exposure age, erosion...

Water mobility in smectite
Water mobility smectite
2012/3/30
The hydrogen in smectite can be broadly separated into five major types according to the association with (i) structural hydroxyl groups, (ii) interlayer water bonded directly to the interlayer cation...
We investigated carrier-relaxation dynamics of femtosecond laser annealed (FLA) polycrystalline silicon (poly-Si). The correlation between morphology and electrical properties of poly-Si after femtose...
Exchange coupling coefficient and domain wall mobility of (Dy,Tb)FeCo magneto-optical films
2011/11/30
The magnetic properties and recording characteristics of ~Dy,Tb!FeCo films are dependent upon the anisotropy dispersion of rare earth constituents and the exchange integral between rare earth and tran...
Recurrent host mobility in spatial epidemics: beyond reaction-diffusion
beyond reaction-diffusion spatial epidemics
2011/9/2
Human mobility is a key factor in spatial disease dynamics and related phenomena. In computational models host mobility is typically modeled by diffusion in space or onmetapolulation networks. Alterna...
Scaling Mobility Patterns and Collective Movements: Deterministic Walks in Lattices
Scaling Mobility Patterns Collective Movements
2011/1/6
Scaling mobility patterns have been widely observed for animals. In this paper, we propose a deterministic walk model to understand the scaling mobility patterns, where walkers take the least-action w...
Peierls-Nabarro energy surfaces and directional mobility of discrete solitons in two-dimensional saturable nonlinear Schrödinger lattices
Pattern Formation and Solitons(nlin.PS) Optics(physics.optics)
2010/11/10
We address the problem of directional mobility of discrete solitons in two-dimensional rectangular lattices, in the framework of a discrete nonlinear Schr\"odinger model with saturable on-site nonline...
Enhancing the electron mobility via delta-doping in SrTiO3
electron mobility delta-doping in SrTiO3
2010/11/17
We fabricated high-mobility δ-doped structures in SrTiO3 thin films in order to investigate the low temperature electronic transport properties of confined carriers in this system. An enhancement of t...
