Decomposing the late positive potential to cannabis cues in regular cannabis users: A temporal-spatial principal component analysis.

open access: yesPsychophysiology, 2023
Cannabis use disorder (CUD) is increasing in the United States, yet, specific neural mechanisms of CUD are not well understood. Disordered substance use is characterized by heightened drug cue incentive salience, which can be measured using the late ...

Wave-packet modulation in shock-containing jets [PDF]

open access: yesPhysical Review Fluids, 2021
We propose a new approach to predict the modulation of wavepackets in shock-containing jets. With a modelled ideally expanded mean flow as input, an approximation of the shock-cell structure is obtained from the parabolised stability equations (PSE) at ...

Interference Mitigation Method for Millimeter-Wave Frequency-Modulation Continuous-Wave Radar Based on Outlier Detection and Variational Modal Decomposition

open access: yesRemote Sensing, 2023
Aiming at the problem of mutual interference between millimeter-wave frequency-modulation continuous-wave (FMCW) radars, an interference mitigation method based on outlier detection and variational mode decomposition (VMD) is proposed in this paper ...

Modulation of angular distribution of scattered ions 12C on nuclei 16O and cluster its substructures

open access: yesRecent Contributions to Physics, 2019
In this paper, the authors considered the question of the experimental study of the 16-O cluster structure by decomposing the experimental angular distributions of differential cross sections into cluster diffraction modes in elastic scattering of ...

A theoretical study of transient stimulated Brillouin scattering in optical fibers seeded with phase-modulated light.

open access: yesOptics Express, 2012
Beam combining of phase-modulated kilowatt fiber amplifiers has generated considerable interest recently. We describe in the time domain how stimulated Brillouin scattering (SBS) is generated in an optical fiber under phase-modulated laser conditions ...

Actively stabilized wavelength-insensitive carrier elimination from an electro-optically modulated laser beam

open access: yes, 2012
We demonstrate a simple and robust technique for removal of the carrier wave from a phase-modulated laser beam, using a noninterferometric method that is insensitive to the modulation frequency and instead exploits the polarization dependence of electro ...

A Justification of the Modulation Approximation to the 3D Full Water Wave Problem

open access: yes, 2014
We consider small amplitude wave packet-like solutions to the 3D inviscid incompressible irrotational infinite depth water wave problem neglecting surface tension. Formal multiscale calculations suggest that the modulation of such a solution is described

Long-term evolution of accretion discs in Be/X-ray binaries [PDF]

open access: yes, 2006
We numerically study the long-term evolution of the accretion disc around the neutron star in a coplanar Be/X-ray binary with a short period and a moderate eccentricity. From three dimensional Smoothed Particle Hydrodynamics simulations, we find that the

Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

open access: yesAdvanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Beating of the oscillations in the transport coefficients of a one-dimensionally periodically modulated two-dimensional electron gas in the presence of spin-orbit interaction

open access: yes, 2004
Transport properties of a two-dimensional electron gas (2DEG) are studied in the presence of a perpendicular magnetic field $B$, of a {\it weak} one-dimensional (1D) periodic potential modulation, and of the spin-orbit interaction (SOI) described only by
