Contact Charge Electrophoresis

http://figshare.com/articles/Contact_Charge_Electrophoresis/1113775

Recently, a new type of electrophoretic transport has been observed - here, termed contact charge electrophoresis (CCEP) - in which a conductive particle or droplet is first charged by contact with an electrode surface in the presence of an electric field and then actuated by that field via electrophoresis. Each time the particle contacts an electrode, its charge changes sign and its velocity changes direction. In contrast to traditional EP and DEP, contact charge electrophoresis allows for rapid, sustained particle motion (>10 cm/s for a micron-scale colloid) driven by low power DC voltages (~1 nW). These attributes make CCEP an ideal mechanism for powering the various active components needed for mobile (i.e., small, battery powered) microfluidic technologies.

'How Data Will Transform Science'

http://www.forbes.com/sites/gregsatell/2014/07/18/how-data-will-transform-science/

"Clearly something has to change.  While the rest of the world has become a highly connected place, driven by new approaches to data and technology, science remains, to an alarming degree, stuck in the last century."

Magnetic field at the surface of a numerical simulation of Earth’s core:

http://figshare.com/articles/Magnetic_field_at_the_surface_of_a_numerical_simulation_of_Earth/1109910

The parameter for this simulations, performed with the XSHELLS spherical code are quite extreme:

Ek = 1e-7,  Ra = 2.4e13,  Pm = 0.1,  Pr = 1

also: Rm=590 and Re=5900.

The radial magnetic field at the surface of the conducting and convecting liquid is shown. It is truncated at spherical harmonic degree 84 before being rendered with matlplotlib.

Trends in Reporting Delays to United States Central #Cancer Registries:

"An evaluation of reporting delay to 10 US cancer registries (the SEER 9 registries plus New York) from 1999-2010 reveals solid downward trends in the amount of delay, which equates to better-quality data. Leukemia and myeloma continue to lag as these sites can be diagnosed and treated outside a hospital setting."

Imperial College London become’s the latest UK institution to release details of their APC charges on figshare:

http://figshare.com/articles/Imperial_APC_data_2006_2014_/1086122

"It lists APCs paid by Imperial College London during 2006-13 and the first two months of 2014. It is likely that many more articles published by Imperial authors were open access, but the full extent is not currently known. Some figures are missing and the data should not be treated as 100% accurate. It may be supplanted at a later date with more complete data."
