Boron-Doped Graphene As Active Electrocatalyst For Oxygen Reduction Reaction At A Fuel-Cell Cathode / Fazio, Gianluca ; Ferrighi, Lara ; Di Valentin, Cristiana
Boron-doped graphene was reported to be the best non-metal doped graphene electrocatalyst for the oxygen reduction reaction (ORR) working at an onset potential of 0.035 V [JACS 136 (2014) 4394]. In the present DFT study, intermediates and transition structures along the possible reaction pathways are determined. [...]

Stochastic cycle selection in active flow networks / Woodhouse, Francis G ; Forrow, Aden ; Fawcett, Joanna B ; Dunkel, Jörn
Active biological flow networks pervade nature and span a wide range of scales, from arterial blood vessels and bronchial mucus transport in humans to bacterial flow through porous media or plasmodial shuttle streaming in slime molds. Despite their ubiquity, little is known about the self-organization principles that govern flow statistics in such non-equilibrium networks. [...]

Intermittency measurement in two dimensional bacterial turbulence / Qiu, Xiang ; Ding, Long ; Huang, Yongxiang ; Chen, Ming ; Lu, Zhiming ; Liu, Yulu ; Zhou, Quan
In this paper, an experimental velocity database of a bacterial collective motion , e.g., \textit{B. subtilis}, in turbulent phase with volume filling fraction $84\%$ provided by Professor Goldstein at the Cambridge University UK, was analyzed to emphasize the scaling behavior of this active turbulence system. [...]

Evolving Horava Cosmological Horizons / Fathi, Mohsen ; Mohseni, Morteza
Several sets of radially propagating null congruence generators are exploited in order to form 3-dimensional marginally trapped surfaces, referred to as black hole and cosmological apparent horizons in a Horava universe. Based on this method, we deal with the characteristics of the 2-dimensional space-like spheres of symmetry and the peculiarities of having trapping horizons. [...]

Gravitational collapse in f(R) gravity for a spherically symmetric spacetime admitting a homothetic Killing vector / Chakrabarti, Soumya ; Banerjee, Narayan
The gravitational collapse of a spherical distribution, in a class of f(R) theories of gravity, where f(R) is power function of R, is discussed. The spacetime is assumed to admit a homothetic Killing vector. [...]

Realistic Detectability of Close Interstellar Comets / Cook, Nathaniel V ; Ragozzine, Darin ; Granvik, Mikael ; Stephens, Denise C
During the planet formation process, billions of comets are created and ejected into interstellar space. The detection and characterization of such interstellar comets (also known as extra-solar planetesimals or extra-solar comets) would give us in situ information about the efficiency and properties of planet formation throughout the galaxy.

Rotation Curve and Mass Distribution in the Galaxy from the Velocities of Objects at Distances up to 200 kpc / Bajkova, A T ; Bobylev, V V
Three three-component (bulge, disk, halo) model Galactic gravitational potentials differing by the expression for the dark matter halo are considered. The central (bulge) and disk components are described by the Miyamoto-Nagai expressions. [...]

Light speed variation from gamma ray burst GRB 160509A / Xu, Haowei ; Ma, Bo-Qiang
It is postulated in Einstein's relativity that the speed of light in vacuum is a constant for all observers. However, the effect of quantum gravity could bring an energy dependence of light speed. [...]

High speed optical holography of retinal blood flow / Pellizzari, Mathilde ; Simonutti, Manuel ; Degardin, Julie ; Sahel, Jose-Alain ; Fink, Mathias ; Paques, Michel ; Atlan, Michael
We performed non-invasive video imaging of retinal blood flow in a pigmented rat by holographic interferometry of near-infrared laser light backscattered by retinal tissue, beating against an off-axis reference beam sampled at a frame rate of 39 kHz with a high throughput camera. Local Doppler contrasts emerged from the envelopes of short-time Fourier transforms and the phase of autocorrelation functions of holograms rendered by Fresnel transformation. [...]

Description and simulation of physics of Resistive Plate Chambers / Français, Vincent
Monte-Carlo simulation of physical processes is an important tool for detector development as it allows to predict signal pulse amplitude and timing, time resolution, efficiency ... Yet despite the fact they are very common, full simulations for RPC-like detector are not widespread and often incomplete. [...]
