 Nanoconfined circular and linear DNA - equilibrium conformations and unfolding kinetics / Alizadehheidari, M ; Werner, E ; Noble, C ; Reiter-Schad, M ; Nyberg, L K ; Fritzsche, J ; Mehlig, B ; Tegenfeldt, J O ; Ambjörnsson, T ; Persson, F et al. Studies of circular DNA confined to nanofluidic channels are relevant both from a fundamental polymer-physics perspective and due to the importance of circular DNA molecules in vivo. We here observe the unfolding of DNA from the circular to linear configuration as a light-induced double strand break occurs, characterize the dynamics, and compare the equilibrium conformational statistics of linear and circular configurations.

 Conjugated liquid layers driven by the short-wavelength B\'enard-Marangoni instability: experiment and numerical simulation / Nejati, Iman ; Dietzel, Mathias ; Hardt, Steffen The coupled dynamics of two conjugated liquid layers of disparate thicknesses, which coat a solid substrate and are subjected to a transverse temperature gradient, is investigated. The upper liquid layer evolves under the short-wavelength (SW) B\'enard-Marangoni (BM) instability, whereas the lower, much thinner film undergoes a shear-driven long-wavelength deformation.

 Short-Time Elasticity of Polymer Melts: Tobolsky Conjecture and Heterogeneous Local Stiffness / Bernini, S ; Leporini, D An extended Molecular-Dynamics study of the short-time "glassy" elasticity exhibited by a polymer melt of linear fully-flexible chains above the glass transition is presented. The focus is on the infinite-frequency shear modulus $G_\infty$ manifested in the picosecond time scale and the relaxed plateau $G_p$ reached at later times and terminated by the structural relaxation.

 Weak links between fast mobility and local structure in molecular and atomic liquids / Bernini, S ; Puosi, F ; Leporini, D We investigate by Molecular-Dynamics simulations the fast mobility - the rattling amplitude of the particles temporarily trapped by the cage of the neighbors - in mildly supercooled states of dense molecular (linear trimers) and atomic (binary mixtures) liquids. The mixture particles interact by the Lennard-Jones potential. [...] arXiv:1605.00867.- 2016 - 11 p. - Published in : The Journal of Chemical Physics 142 (2015) 124504 External link: Preprint

 Cage rattling does not correlate with the local geometry in molecular liquids / Bernini, S ; Puosi, F ; Leporini, D Molecular-dynamics simulations of a liquid of short linear molecules have been performed to investigate the correlation between the particle dynamics in the cage of the neighbors and the local geometry. The latter is characterized in terms of the size and the asphericity of the Voronoi polyhedra.

 Optical atomic magnetometry for magnetic induction tomography of the heart / Deans, Cameron ; Marmugi, Luca ; Hussain, Sarah ; Renzoni, Ferruccio We report on the use of radio-frequency optical atomic magnetometers for magnetic induction tomography measurements. We demonstrate the imaging of dummy targets of varying conductivities placed in the proximity of the sensor, in an unshielded environment at room-temperature and without background subtraction.

 Geometric Metasurface Fork Gratings for Vortex Beam Generation and Manipulation / Chen, Shumei ; Cai, Yuan ; Li, Guixin ; Zhang, Shuang ; Cheah, Kok Wai In recent years, optical vortex beams possessing orbital angular momentum have caught much attention due to their potential for high capacity optical communications. This capability arises from the unbounded topological charges of orbital angular momentum (OAM) that provides infinite freedoms for encoding information.

 Performance of the finite volume method in solving regularised Bingham flows: inertia effects in the lid-driven cavity flow / Syrakos, Alexandros ; Georgiou, Georgios C ; Alexandrou, Andreas N We extend our recent work on the creeping flow of a Bingham fluid in a lid-driven cavity, to the study of inertial effects, using a finite volume method and the Papanastasiou regularisation of the Bingham constitutive model [J. Rheology 31 (1987) 385-404]. [...] arXiv:1605.00590.- 2016 - Published in : Journal of Non-Newtonian Fluid Mechanics 20 (2014) 88-107 External link: Preprint

 The interaction of $He^{-}$ with fullerenes / Mauracher, A ; Daxner, M ; Huber, S E ; Postler, J ; Renzler, M ; Denifl, S ; Scheier, P ; Ellis, A M The effects of interactions between He- and clusters of fullerenes in helium nanodroplets are described. Electron transfer from $He^{-}$ to $(C_{60})_n$ and $(C_{70})_n$ clusters results in the formation of the corresponding fullerene cluster dianions. [...] arXiv:1605.00537.- 2016 - Published in : J.

 Localized travelling waves in the asymptotic suction boundary layer / Kreilos, Tobias ; Gibson, John F ; Schneider, Tobias M We present two spanwise-localized travelling wave solutions in the asymptotic suction boundary layer, obtained by continuation of solutions of plane Couette flow. One of the solutions has the vortical structures located close to the wall, similar to spanwise-localized edge states previously found for this system.
