 On the Vortex Dynamics in Fractal Fourier Turbulence / Lanotte, Alessandra S ; Malapaka, Shiva Kumar ; Biferale, Luca Incompressible, homogeneous and isotropic turbulence is studied by solving the Navier-Stokes equations on a reduced set of Fourier modes, belonging to a fractal set of dimension $D$. By tuning the fractal dimension parameter, we study the dynamical effects of Fourier decimation on the vortex stretching mechanism and on the statistics of the velocity and the velocity gradient tensor.

 Viscoplastic flow in an extrusion damper / Syrakos, Alexandros ; Dimakopoulos, Yannis ; Georgiou, Georgios C ; Tsamopoulos, John Numerical simulations of the flow in an extrusion damper are performed using a finite volume method. The damper is assumed to consist of a shaft, with or without a spherical bulge, oscillating axially in a containing cylinder filled with a viscoplastic material of Bingham type.

 Nanoscopic Characterization of DNA within Hydrophobic Pores:Thermodynamics and Kinetics / Cruz, Fernando J A L ; de Pablo, Juan J ; Mota, José P B The energetic and transport properties of a double-stranded DNA dodecamer encapsulated in hydrophobic carbon nanotubes are probed employing two limiting nanotube diameters, D=4 nm and D=3 nm, corresponding to (51,0) and (40,0) zig-zag topologies, respectively. It is observed that the thermodynamically spontaneous encapsulation in the 4 nm nanopore (40 kJ/mol) is annihilated when the solid diameter narrows down to 3 nm, and that the confined DNA termini directly contact the hydrophobic walls with no solvent slab in-between.

 Thermodynamics of adsorption of light alkanes and alkenes in single-walled carbon nanotube bundles / Cruz, Fernando J A L ; Mota, José P B The thermodynamics of adsorption of light alkanes and alkenes (CH4, C2H6, C2H4, C3H8, and C3H6) in single-walled carbon nanotube bundles is studied by configurational-bias grand canonical Monte Carlo simulation. The bundles consist of uniform nanotubes with diameters in the range 11.0 < D (A) < 18.1, arranged in the usual close-packed hexagonal lattice. [...] arXiv:1605.01356.- 2016 - Published in : Phys.

 Parker's model in geodynamo / Reshetnyak, M We consider how information on geostrophic flows in the planetary cores, taken from 3D simulations in the sphere, can be used in 2D Parker's geodynamo model with the simple forms of the $\alpha$-quenching. Using cluster computer systems dependence of dynamo equations solution on the magnitudes of $\alpha$- and $\omega$-effects is studied. [...] arXiv:1605.01321.- 2016 External link: Preprint

 Endohedral confinement of a DNA dodecamer onto pristine carbon nanotubes and the stability of the canonical B form / Cruz, Fernando J A L ; de Pablo, Juan J ; Mota, José P B Although carbon nanotubes are potential candidates for DNA encapsulation and subsequent delivery of biological payloads to living cells, the thermodynamical spontaneity of DNA encapsulation under physiological conditions is still a matter of debate. Using enhanced sampling techniques, we show for the first time that, given a sufficiently large carbon nanotube, the confinement of a double-stranded DNA segment, 5'-D(*CP*GP*CP*GP*AP*AP*TP*TP*CP*GP*CP*G)-3', is thermodynamically favourable under physiological environments (134 mM, 310 K, 1 bar), leading to DNA-nanotube hybrids with lower free energy than the unconfined biomolecule.

 A new look at the Feynman `hodograph' approach to the Kepler first law / Cariñena, Jose F ; Rañada, M F ; Santander, M Hodographs for the Kepler problem are circles. This fact, known since almost two centuries ago, still provides the simplest path to derive the Kepler first law. [...] arXiv:1605.01204.- 2016 - Published in : Eur. J.

 Community Evolution / Bródka, Piotr ; Saganowski, Stanisław ; Kazienko, Przemysław The continuous interest in the social network area contributes to the fast development of this field. The new possibilities of obtaining and storing data facilitate deeper analysis of the entire social network, extracted social groups and single individuals as well.

 Diversity improves performance in excitable networks / Gollo, Leonardo L ; Copelli, Mauro ; Roberts, James A As few real systems comprise indistinguishable units, diversity is a hallmark of nature. Diversity among interacting units shapes properties of collective behavior such as synchronization and information transmission.

 Dwelling Quietly in the Rich Club: Brain Network Determinants of Slow Cortical Fluctuations / Gollo, Leonardo L ; Zalesky, Andrew ; Hutchison, R Matthew ; Heuvel, Martijn van den ; Breakspear, Michael For more than a century, cerebral cartography has been driven by investigations of structural and morphological properties of the brain across spatial scales and the temporal/functional phenomena that emerge from these underlying features. The next era of brain mapping will be driven by studies that consider both of these components of brain organization simultaneously -- elucidating their interactions and dependencies.
