Electroencephalogram evidence for memory suppression : a systematic review
(2019) [Artículo de periódico]Understanding how people forget is one of the fundamental goals of the science of memory. Recent studies indicate that humans can voluntarily regulate awareness of unwanted memories by stopping the retrieval process that ... -
Electrofission of (sup 239) pu in the energy range 7-12 mev
(1997) [Artículo de periódico]The electrofission cross section of ²³⁹Pu(e,f) is measured between 7 and 12 MeV. The data are analyzed by means of the virtual photon formalism, assuming that E1, E2 (T=0), and M1 transitions are involved. Using known ... -
Electroluminescence induced by Ge nanocrystals obtained by hot ion implantation into SiO2
(2009) [Artículo de periódico]Commonly, electroluminescence (EL) from Ge nanocrystals (Ge NCs) has been obtained by room temperature (RT) Ge implantation into a SiO2 matrix followed by a high temperature anneal. In the present work, we have used a novel ... -
Electrolytes between dielectric charged surfaces : simulations and theory
(2015) [Artículo de periódico]We present a simulation method to study electrolyte solutions in a dielectric slab geometry using a modified 3D Ewald summation. The method is fast and easy to implement, allowing us to rapidly resum an infinite series of ... -
Electromagnetic weak turbulence theory revisited
(2012) [Artículo de periódico]The statistical mechanical reformulation of weak turbulence theory for unmagnetized plasmas including fully electromagnetic effects was carried out by Yoon [Phys. Plasmas 13, 022302 (2006)]. However, the wave kinetic ... -
Electromigration aware cell design
(2015) [Tesis]Electromigration (EM) in on-chip metal interconnects is a critical reliability failure mechanism in nanometer-scale technologies. Usually works in the literature that address EM are concerned with power network EM and cell ... -
