People who share a political ideology have more similar ‘neural fingerprints’ of political words and process new information in similar ways, according to a new analysis led by Brown University resear...
A technical note on the bias in the estimation of the b-value and its uncertainty through the Least Squares technique
b-value Seismology Least Squares technique Synthetic-earthquake catalogs
2015/9/2
We investigate conceptually,
analytically, and numerically the biases in the estimation of the
b-value of the Gutenberg-Richter law and of
its uncertainty made through the least
squares technique...
On the crustal bias of repeat stations in Romania
Geomagnetic field Secular variation Repeat station network Romania
2015/8/26
A magnetic induction model has been applied to recordings obtained in 2010 during the field campaigns for geomagnetic measurements at the 26 repeat stations of the Romanian secular variation network. ...

Media Bias and Reputation
Media Bias Reputation
2015/7/17
A Bayesian consumer who is uncertain about the quality of an information source will infer that the source is of higher quality when its
reports conform to the consumer’s prior expectations. We use t...
We analyze the natural process of flipping a coin which is caught in the hand. We show that vigorously flipped coins tend to come up the same way they started. The limiting chance of comin...
Lyman Alpha Absorber Correlations and the Bias of the Lyman Alpha Forest
BIAS THE Lyman Alpha Forest
2014/12/26
Lyman alpha absorber correlations contain information about the underlying density distribution associated with a particular class of absorbers. As such, they provide an opportunity to independently m...
Galaxy clustering and galaxy bias in a Lambda CDM universe
formation large-scale structure of universe
2014/12/24
We investigate galaxy clustering and the correlations between galaxies and mass in the ΛCDM cosmological model (inflationary cold dark matter with Ωm = 0.4, ΩΛ = 0.6, h = 0.65, n = 0.95, and σ8 = 0.8)...
With a high spatial resolution imaging instrument such as the Chandra ACIS, one can confidently identify an X-ray source with only a few detected counts. The detection threshold of such sources, howev...
A pragmatic approach for the downscaling and bias correction of regional climate simulations: evaluation in hydrological modeling

2014/12/9
The present study investigates a statistical approach for the downscaling of climate simulations focusing on those meteorological parameters most commonly required as input for climate change impact m...
A RVR-based Method for Bias Field Estimation in Brain Magnetic Resonance Images Segmentation
A RVR-based Method Bias Field Estimation Brain Magnetic Resonance Images Segmentation
2018/4/19
Abstract— This paper presents a relevance vector regression (RVR) based parametric approach to the bias field estimation in brain magnetic resonance (MR) image segmentation. Segmentation is a very imp...
Hierarchical Consensus Formation Reduces the Influence of Opinion Bias
Hierarchical Consensus Formation Influence of Opinion Bias Physics and Society
2012/4/19
We study the role of hierarchical structures in a simple model of collective consensus formation based on the bounded confidence model with continuous individual opinions. For the particular variation...
Effects of substrate bias on the magnetic properies and microsture of both rf-magnetron and dc-magnetron sputtered magneto-optical recording thin films of TbCo were investigated.It is shown that as an...

2014/5/20
Most of current general circulation models (GCMs) show a remarkable positive precipitation bias over the southwestern equatorial Indian Ocean (SWEIO), which can be thought of as a westward expansion o...
Merger induced scatter and bias in the cluster mass - Sunyaev-Zeldovich effect scaling relation

2011/10/20
We examine sources of scatter in scaling relations between galaxy cluster mass and thermal Sunyaev-Zeldovich (SZ) effect using cluster samples extracted from cosmological hydrodynamical simulations. O...
