Predicting the variance of a measurement with 1/f noise / Lenoir, Benjamin
Measurement devices always add noise to the signal of interest and it is necessary to evaluate the variance of the results. This article focuses on stationary random processes whose Power Spectrum Density is a power law of frequency. [...]

Efficient kinetic Monte Carlo method for reaction-diffusion processes with spatially varying annihilation rates / Schwarz, Karsten ; Rieger, Heiko
We present an efficient Monte Carlo method to simulate reaction-diffusion processes with spatially varying particle annihilation or transformation rates as it occurs for instance in the context of motor-driven intracellular transport. Like Green's function reaction dynamics and first-passage time methods, our algorithm avoids small diffusive hops by propagating sufficiently distant particles in large hops to the boundaries of protective domains. [...]

The EUROnu Project / Edgecock, T R ; Caretta, O ; Davenne, T ; Densham, C ; Fitton, M ; Kelliher, D ; Loveridge, P ; Machida, S ; Prior, C ; Rogers, C et al.
The EUROnu project has studied three possible options for future, high intensity neutrino oscillation facilities in Europe. The first is a Super Beam, in which the neutrinos come from the decay of pions created by bombarding targets with a 4 MW proton beam from the CERN High Power Superconducting Proton Linac. [...]

Statistically optimal fitting of astrometric signals / Gai, M ; Busonero, D ; Cancelliere, R
A general purpose fitting model for one-dimensional astrometric signals is developed, building on a maximum likelihood framework, and its performance is evaluated by simulation over a set of realistic image instances. The fit quality is analysed as a function of the number of terms used for signal expansion, and of astrometric error, rather than RMS discrepancy with respect to the input signal. [...]

Observations of very high energy gamma-ray emission from AGNs with the ground-based EAS arrays / CHEN, SongZhan
The ground-based EAS array is usually operated with a high duty cycle (> 90%) and a large field of view (~2 sr), which can continuously monitor the sky. It is essential and irreplaceable to understand the gamma-ray emission mechanism and intrinsic physics progress of the variable source AGN. [...]

MHD Disc Winds and Linewidth Distributions / Chajet, Laura S ; Hall, Patrick B
We study AGN emission line profiles combining an improved version of the accretion disc-wind model of Murray & Chiang with the magneto-hydrodynamic model of Emmering et al. We show how the shape, broadening and shift of the C IV line depend not only on the viewing angle to the object but also on the wind launching angle, especially for small launching angles. [...]

Davydov's Solitons in a Homogeneous Nucleotide Chain / Lakhno, Victor D
Charge transfer in homogeneous nucleotide chains is modeled on the basis of Holstein Hamiltonian. The path length of Davydov solitons in these chains is being studied. [...]

Toroidal modeling of penetration of the resonant magnetic perturbation field / Liu, Yueqiang ; Kirk, A ; Sun, Y
A toroidal, quasi-linear model is proposed to study the penetration dynamics of the resonant magnetic perturbation (RMP) field into the plasma. The model couples the linear, fluid plasma response to a toroidal momentum balance equation, which includes torques induced by both fluid electromagnetic force and by (kinetic) neoclassical toroidal viscous force.

Towards understanding edge localised mode mitigation by resonant magnetic perturbations in MAST / Chapman, I T ; Kirk, A ; Ham, C J ; Harrison, J R ; Liu, Y Q ; Saarelma, S ; Scannell, R ; Thornton, A J ; Becoulet, M ; Orain, F et al. /MAST Team
Type-I Edge Localised Modes (ELMs) have been mitigated in MAST through the application of n = 3, 4 and 6 resonant magnetic perturbations (RMPs). For each toroidal mode number of the non-axisymmetric applied fields, the frequency of the ELMs has been increased significantly, and the peak heat flux on the divertor plates reduced commensurately.

Toroidal modeling of interaction between resistive wall mode and plasma flow / Liu, Yueqiang ; Sun, Youwen
The non-linear interplay between the resistive wall mode (RWM) and the toroidal plasma flow is numerically investigated in a full toroidal geometry, by simultaneously solving the initial value problems for the n=1 RWM and the n=0 toroidal force balance equation. Here n is the toroidal mode number. [...]
