Investigating and counteracting popularity bias in group recommendations
(Elsevier, 2021)
Popularity bias is an undesirable phenomenon associated with recommendation algorithms where popular items tend to be suggested over long-tail ones, even if the latter would be of reasonable interest for individuals. Such ...
Novel automatic group identification approaches for group recommendation
(Elsevier, 2021)
Group recommender systems are specialized in suggesting preferable products or services to a group of users rather than an individual by aggregating personal preferences of group members. In such expert systems, the initial ...
An entropy empowered hybridized aggregation technique for group recommender systems
(Elsevier, 15.03.2021)
Group recommender systems aim to suggest appropriate products/services to a group of users rather than individuals. These recommendations rely solely on determining group preferences, which is accomplished by an aggregation ...
Association between lower extremity venous insufficiency and duration of atrial fibrillation
(Sage, 2021)
Objective: Physiologic studies have shown that atrium has an active role in venous blood return from lower extremity.
In this context we investigated the association between AF and chronic venous disease (CVD).
Methods: ...
Generation of even and odd harmonics in the XUV region with controlling the relative delay and polarization of two-color fields
(Elsevier, 2021)
We report high harmonic generation in the extreme ultraviolet (XUV) region by using two-color
laser fields at the wavelengths of 800 nm and 400 nm. With a Ti: sapphire femtosecond laser at a
10 Hz repetition rate efficient ...
Intensity-dependent nonlinear optical properties in an asymmetric Gaussian potential quantum well-modulated by external fields
(Springer, 2021)
In this paper, the efects of external electric, magnetic and non-resonant intense laser felds
on the nonlinear optical rectifcation (NOR), second-harmonic (SH), and third harmonic
(TH) generation in a GaAs quantum well ...
Computation of Atomic Dipole Spectra for Different Atoms by Considering Short and Long Electron Trajectories under the Intense Laser Pulse
(9TH INTERNATIONAL ADVANCED TECHNOLOGIES SYMPOSIUM, 2021)
In this work, computation of the nonlinear dipole response of a single atom is performed by considering
the ionization of the electron under the intense laser field. The dipole spectra for xenon (Xe) and argon
(Ar) gases ...
Effect of Ultrashort Laser Pulse Shape on the Dipole Spectrum of a Single Electron
(International Conference on Advances in Engineering, Architecture, Science and Technology (ICAEAST 2021)), 2021)
In this study, the effects of ultrashort laser pulse shape for the laser-matter interaction have been considered. Three
different pulse shapes, Gaussian, Super-Gaussian, and Cosine-Squared, are used to calculate the dipole ...
Influence of hydrostatic pressure, temperature, and terahertz laser field on the electron-related optical responses in an asymmetric double quantum well
(Springer, 2021)
In this study, the effects of hydrostatic pressure, temperature, and high-frequency intense laser
field on the nonlinear optical properties of an asymmetric GaAs/AlGaAs double quantum well was theoretically investigated. ...
Estimations of (n, p) reaction cross-sections at 14.5 MeV incident neutron energy by artificial neural networks
(2021)
The cross-sections for (n, p) reactions around 14 MeV are important for nuclear research field and applications of nuclear energy. Also these neutron-induced reactions have been extensively studied in the literature. In ...
