Numerous experiments demonstrate attitude polarization. For instance, Lord, Ross & Lepper presented subjects with the same mixed evidence on the deterrent effect of the death penalty. Both believers and skeptics of its ...

This study focuses on the 15 May 2005 geomagnetic superstorm and aims to investigate the global variation of positive and negative storm phases and their development. Observations are provided by a series of global total ...

Cells are naturally surrounded by organized electrical signals in the form of local ion fluxes, membrane potential, and electric fields (EFs) at their surface. Although the contribution of electrochemical elements to cell ...

We perform a careful study on the effect of the Pauli blocking to the light polarized antiquark structure of the proton sea. We develop the formal expressions for the polarized antiquark distributions, highlighting the ...

The effect of wage polarization on total factor productivity (TFP) in the Spanish regions between 2004 and 2012 is analysed using dynamic panel estimates. The main finding of this research is that there seems to be some ...

Microtubules are the largest cytoskeleton filaments and are essential for intracellular transport, organelle positioning, cell morphology and motility. In cells, the dynamic regulation of the microtubule network is controlled ...

Peer review reports on scientific articles means a key genre to explain how scientific knowledge is collectively constructed. In these reports, reviewers write a recommendation for publication along with a series of comments. ...
