Increased frequencies of activating natural killer receptors are associated with liver injury in individuals who do not eliminate hepatitis C virus
(Wiley Blackwell Publishing, Inc, 2007-12)
This study was designed to investigate the role of KIR genes in the outcome of HCV infection. In patients who cleared the virus (HCV RNA-) we found a decrease of 2DL2 (p=0.04), and 2DS2 (p=0.014) accompanied by an increase ...

The 10 Hz frequency: A fulcrum for transitional brain states
(Open Access Text, 2016-04)
A 10 Hz rhythm is present in the occipital cortex when the eyes are closed (alpha waves), in the precentral cortex at rest (mu rhythm), in the superior and middle temporal lobe (tau rhythm), in the inferior olive (projection ...
Error estimation and h-adaptive refinement in the analysis of natural frequencies
(ELSEVIER SCIENCE BV, 2001-12-01)
This paper deals with the estimation of the discretization error and the definition of an optimum h-adaptive process in the finite element analysis of natural frequencies and modes. Consistent and lumped mass matrices are ...
Characterization of cross frequency couplings produced by harmonic and non-harmonic frequency bands during seizure activity from intracerebral recordings in patients candidate to epilepsy surgery
(Society for Neuroscience, 2018)
Cross frequency coupling (CFC) phenomenon has been proposed to be functionally involved in neuronal communication, memory formation and learning. Besides, experimental findings have shown that phase-amplitude (PAC) and ...

Debris flow susceptibility mapping using frequency ratio and seed cells, in a portion of a mountain international route, Dry Central Andes of Argentina
(Elsevier Science, 2020-06)
Debris flow and floods represent one of the main natural hazards that impact transport infrastructure, causing serious damage, economic losses and hinder regional economic development. These processes are eventually ...
