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 ...
Treating adverse effects of blockbuster bias on beyond-accuracy quality of personalized recommendations
(Elsevier, 2022)
Collaborative filtering recommendation algorithms are vulnerable against the popularity bias, including the most popular items repeatedly into the produced ranked lists. However, the research on popularity bias focuses ...
Optimizing Non-linear Granular Layer Coefficients of a Flexible Pavement for Mechanistic-Empirical Method
(2021)
In recent years, mechanistic-empirical (M-E) design methods are preferred in the design of
flexible pavements instead of empirical methods using equations based on the road
performance tests. However, the calibration of ...
Effect of functional grading on the performance of flexible pavements
(2021)
Fatigue failure is an important type of pavement distress which is considered in the pavement design. In
this study, it is aimed to increase the fatigue strength of the pavement without using any additives. For this
purpose, ...
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 ...
Nanoparticles with PDT and PTT synergistic properties working with dual NIR-light source simultaneously
(2021)
A non-toxic nano system using a cleverly designed dual light can be an important treatment strategy in
cancer therapy. Here, we propose a unique concept of synergistic non-toxic nanoplatform, which
operates with dual ...
Generation of Coherent Extreme Ultraviolet Radiation in an Air Gas Cell with a High Power Femtosecond Laser System
(Springer, 2021)
High harmonic generation (HHG) in air medium is experimentally produced by using a state-ofthe-art high power laser system. The harmonic orders up to 35th harmonic are well observed. Optical power
dependence of harmonic ...
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 ...
