Dopamine Modulates Delta-Gamma Phase-Amplitude Coupling in the Prefrontal Cortex of Behaving Rats
(Frontiers in Bioscience, 2017-05)
Dopamine release and phase-amplitude cross-frequency coupling (CFC) have independently been implicated in prefrontal cortex (PFC) functioning. To causally investigate whether dopamine release affects phase-amplitude ...
SPICE Simulation of RRAM-Based Cross-Point Arrays Using the Dynamic Memdiode Model
(Frontiers Media, 2021-09)
We thoroughly investigate the performance of the Dynamic Memdiode Model (DMM) when used for simulating the synaptic weights in large RRAM-based cross-point arrays (CPA) intended for neuromorphic computing. The DMM is in ...
Coupled plasmonic graphene wires: theoretical study including complex frequencies and field distributions of bright and dark surface plasmons
(Optical Society of America, 2020-10)
Theoretical research on localized surface plasmons (LSPs) supported by a structure formed by two parallel dielectric wires with a circular cross section wrapped with a graphene sheet has an impact in the practical realm. ...
Exact solutions for coupled free vibrations of tapered shear-flexible thin-walled composite beams
(Academic Press Ltd - Elsevier Science Ltd, 2008-09-23)
In this paper, analytical solutions for the free vibration analysis of tapered thin-walled laminated-composite beams with both closed and open cross-sections are developed. The present study is based on a recently developed ...
Signatures of a quantum dynamical phase transition in a three-spin system in presence of a spin environment
(Elsevier Science, 2007-12)
We have observed an environmentally induced quantum dynamical phase transition in the dynamics of a two-spin experimental swapping gate [G.A. Álvarez, E.P. Danieli, P.R. Levstein, H.M. Pastawski, J. Chem. Phys. 124 (2006) ...
Desvendando oscilações hipocampais através de comodulações
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM NEUROCIÊNCIAS, 2016-04-07)
Spectral analysis of extracellular electrophysiological recordings revealed that the
brain electrical activity is often organized in rhythmic patterns, known as neuronal
oscillations. Recently, it was discovered that ...
Design and simulation of triplexer for mobile communications using trisection resonators filters
(Scopus, 2013)
This paper presents a microstrip triplexer with multiband performances by using cascaded trisection (CT) filters. Each CT section is composed by three directly coupled resonators with a cross coupling. The cross coupling ...
Reduced cardio-respiratory coupling indicates suppression of vagal activity in healthy relatives of patients with schizophrenia
(Elsevier Inc, 2010-03)
Previous studies have observed reduced vagal modulation in patients with acute schizophrenia and their first-degree relatives, thus suggesting a genetic predisposition. To investigate vagal modulation, we analyzed the ...
Dynamics of frequency-swept nuclear spin optical pumping in powdered diamond at low magnetic fields
(National Academy of Sciences, 2019-02)
A broad effort is underway to improve the sensitivity of NMR through the use of dynamic nuclear polarization. Nitrogen vacancy (NV) centers in diamond offer an appealing platform because these paramagnetic defects can be ...
