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 ...
Evaluating unfairness of popularity bias in recommender systems: A comprehensive user-centric analysis
(Elsevier, 2022)
The popularity bias problem is one of the most prominent challenges of recommender systems,
i.e., while a few heavily rated items receive much attention in presented recommendation
lists, less popular ones are underrepresented ...
Effects of Applied Magnetic Field on the Optical Properties and Binding Energies Spherical GaAs Quantum Dot with Donor Impurity
(2022/8/10)
The screened modified Kratzer potential (SMKP) model is utilized to scrutinize the impacts of an applied magnetic field (MF) on the binding energies and linear and nonlinear optical properties spherical GaAs quantum dot ...
Photoionization cross section of a D-2(+) complex in quantum dots: the role of donor atoms configuration
(2022/8/1)
This study reports a theoretical investigation on the electronic spectrum and the photoionization cross section of a singly ionized double donor complex D_2^+ confined in a two-dimensional quantum dot with Gaussian confinement ...
Exploring potential biases towards blockbuster items in ranking-based recommendations
(Springer, 2022)
Popularity bias is defined as the intrinsic tendency of recommendation algorithms to feature popular items more than unpopular ones in the ranked lists lists they produced. When investigating the adverse effects of popularity ...
Effects of Intense Laser Field on Electronic and Optical Properties of Harmonic and Variable Degree Anharmonic Oscillators
(2022)
In this paper, we calculated the electronic and optical properties of the harmonic oscillator
and single and double anharmonic oscillators, including higher-order anharmonic terms such as
the quartic and sextic under the ...
Paleolithic Human Responses to Changing Aridity at ucagizli I cave, southern-coastal Turkey: Application of a Novel Carbon Isotope-Based Method
(2022)
This paper investigates relationships between intervals of local environmental aridity
and site occupation intensity at the Upper Paleolithic cave site of Üçağızlı I (Hatay
coast, south-central Turkey) by combining a ...
Shallow‑donor impurity effects on the far infrared electron–electron optical absorption coefficient in single and core/shell spherical quantum dots with Konwent‑like confinement potential
(2022)
In this study, the electronic and optical properties of single or core/shell quantum dots,
which are formed depending on the parameters in the selected Konwent potential, are
investigated. Namely, the effects of the size ...
Optical Properties of Cylindrical Quantum Dots with Hyperbolic-Type Axial Potential under Applied Electric Field
(2022)
In this paper, we have researched the electronic and optical properties of cylindrical
quantum dot structures by selecting four different hyperbolic-type potentials in the axial direction
under an axially-applied electric ...
Ancient DNA from Mesopotamia suggests distinct Pre-Pottery and Pottery Neolithic migrations into Anatolia
(American Association for the Advancement of Science, 2022)
We present the first ancient DNA data from the Pre-Pottery Neolithic of Mesopotamia (Southeastern Turkey and Northern Iraq), Cyprus, and the Northwestern Zagros, along with the first data from Neolithic Armenia. We show ...
