Particle scattering in turbulent plasmas with amplified wave modes [PDF]

open access: yes, 2013
High-energy particles stream during coronal mass ejections or flares through the plasma of the solar wind. This causes instabilities, which lead to wave growth at specific resonant wave numbers, especially within shock regions. These amplified wave modes

Pixelating Familiar People in the Media: Should Masking Be Taken at Face Value? [PDF]

open access: yes, 2007
This study questions the effectiveness of masking faces by means of pixelation on television or in newspapers. Previous studies have shown that masking just the face leads to unacceptably high recognition levels, making it likely that participants also ...

The mathematical basis for deterministic quantum mechanics

open access: yes, 2006
If there exists a classical, i.e. deterministic theory underlying quantum mechanics, an explanation must be found of the fact that the Hamiltonian, which is defined to be the operator that generates evolution in time, is bounded from below. The mechanism

Method and apparatus for predicting the direction of movement in machine vision [PDF]

open access: yes, 1992
A computer-simulated cortical network is presented. The network is capable of computing the visibility of shifts in the direction of movement. Additionally, the network can compute the following: (1) the magnitude of the position difference between the ...

Characterizing temporary hydrological regimes at a European scale [PDF]

open access: yes, 2011
Monthly duration curves have been constructed from climate data across Europe to help address the relative frequency of ecologically critical low flow stages in temporary rivers, when flow persists only in disconnected pools in the river bed.

Mean radiant temperature from global-scale numerical weather prediction models [PDF]

open access: yes, 2020
In human biometeorology, the estimation of mean radiant temperature (MRT) is generally considered challenging. This work presents a general framework to compute the MRT at the global scale for a human subject placed in an outdoor environment and ...

Prediction of overwash in alongshore variable barrier islands [Previsão da ocorrência de galgamentos em ilhas barreira com variabilidade longilitoral] [PDF]

open access: yes, 2019
Overwash prediction is very important for coastal zone management. This work intends to identify alongshore variations in storm impact and evaluate the role of sub-aerial and submerged morphologies in overwash occurrence.

Assessing plantar sensation in the foot using the FOot Roughness Discrimination Test (FoRDT™): a reliability and validity study in stroke [PDF]

open access: yes, 2019
BACKGROUND: The foot sole represents a sensory dynamometric map and is essential for balance and gait control. Sensory impairments are common, yet often difficult to quantify in neurological conditions, particularly stroke.

Avoiding misleading estimates of among‐individual variance caused by non‐random sampling of individuals in a changeable environment

open access: yesMethods in Ecology and Evolution
Animal ecologists frequently quantify variance in hierarchically structured traits in wild populations. Importantly, phenotypic plasticity within the period of measurement can modify the trait of interest in response to various unmeasured, temporally or ...

A method for evaluating the degree of housing unit flexibility in multi-family housing [PDF]

open access: yes, 2012
The flexibility of housing unit is achieved through a complex design process which includes an analysis of influencing factors of flexibility, their potentials and limitations for the purpose of improvement of residential space organization.
