Chiral Nonet Mixing in Scattering
Amir H. Fariborz, Soodeh Zarepour, Esmaiel Pourjafarabadi +1
The generalized linear sigma model for mixing among two- and four-quark components of scalar (and psedudosclar) mesons below and above 1 GeV is applied to the channel in which…
Superradiant energy extraction from rotating hairy Horndeski black holes
Sohan Kumar Jha, Mohsen Khodadi, Anisur Rahaman +1
Adopting the manifest of low-frequency and low mass for the scalar perturbation, we perform a semi-classical analysis of the superradiance phenomenon for a rotating hairy Horndeski…
Constraining the Lorentz-Violating Bumblebee Vector Field with Big Bang Nucleosynthesis and Gravitational Baryogenesis
Mohsen Khodadi, Gaetano Lambiase, Ahmad Sheykhi
By keeping the cosmological principle i.e., an isotropic and homogeneous universe, we consider the cosmology of a vector-tensor theory of gravitation known as the \textit{bumblebee…
Shadow of black hole surrounded by magnetized plasma: Axion-plasmon cloud
Mohsen Khodadi
By exploiting the extreme environment of the black hole (BH) as a potential place for axion-photon interaction, we use an axion-producing model of the magnetized plasma to study th…
Holographic dark energy in modified Barrow cosmology
Ahmad Sheykhi, Maral Sahebi Hamedan
Thermodynamics-Gravity conjecture implies that there is a deep connection between the gravitational field equations and the first law of thermodynamics. Therefore, any modification…
Lifetime of scalar cloud formation around a rotating regular black hole
Mohsen Khodadi, Reza Pourkhodabakhshi
Does circumventing the curvature singularity of the Kerr black hole affects the timescale of the scalar cloud formation around it? By definition, the scalar cloud, forms a gravitat…
Modified cosmology through Barrow entropy
Ahmad Sheykhi
We investigate the cosmological consequences of the modified Friedmann equations when the entropy associated with the apparent horizon, given by Barrow entropy, ,…
Gauss-Bonnet black holes in a special anisotropic scaling spacetime
S. Mahmoudi, Kh. Jafarzade, S. H. Hendi
Inspired by the Lifshitz gravity as a theory with anisotropic scaling behavior, we suggest a new dimensional metric in which the time and spatial coordinates scale anisotro…
Entropic corrections to Friedmann equations and bouncing universe due to the zero-point length
Kimet Jusufi, Ahmad Sheykhi
We employ Verlinde's entropic force scenario to extract the modified Friedmann equations by taking into account the zero-point length correction to the gravitational potential. Sta…
Application of Deep Learning in Generating Structured Radiology Reports: A Transformer-Based Technique
Seyed Ali Reza Moezzi, Abdolrahman Ghaedi, Mojdeh Rahmanian +2
Since radiology reports needed for clinical practice and research are written and stored in free-text narrations, extraction of relative information for further analysis is difficu…
Using Word Embedding and Convolution Neural Network for Bug Triaging by Considering Design Flaws
Reza Sepahvand, Reza Akbari, Behnaz Jamasb +2
Resolving bugs in the maintenance phase of software is a complicated task. Bug assignment is one of the main tasks for resolving bugs. Some Bugs cannot be fixed properly without ma…
On observational signatures of multi-fractional theory
Mahnaz Asghari, Ahmad Sheykhi
We study the multi-fractional theory with -derivatives, where the multi-fractional measure is considered to be in the time direction. The evolution of power spectra and also the…
Patterns for ghost imaging generated by the Ising model
Hamidreza Oliaei-Moghadam, Chane Moodley, Mahmood Hosseini-Farzad
We offer new illumination patterns for imaging in all-digital ghost imaging (GI) systems. The digital patterns, written as computer generated holograms on spatial light modulators…
Dark Energy Star in Gravity's Rainbow
A. Bagheri Tudeshki, G. H. Bordbar, B. Eslam Panah
The concept of dark energy can be a candidate for preventing the gravitational collapse of compact objects to singularities. According to the usefulness of gravity's rainbow in UV…

S. N. Sajadi, S. H. Hendi
In this work, we introduce an analytical approximate black hole solution in Einstein-Cubic gravity. To obtain complete solutions, we construct the near horizon and asymptotic solut…
Charged Black Holes in Einsteinian Quartic Gravity
S. N. Sajadi, Leila Shahkarami, Farid Charmchi +1
In this paper, we studied Einsteinian quartic gravity minimally coupled to electrodynamics in four dimensions. First, by variation action, we obtain the field equations, and by int…
No Evolution in the Half-mass Radius of Milky Way-type Galaxies over the Last 10 Gyr
Maryam Hasheminia, Moein Mosleh, Sandro Tacchella +3
The Milky Way (MW) galaxy is in focus, thanks to new observational data. Here we shed new light on the MW's past by studying the structural evolution of MW progenitors, which we id…
Foliated order parameter in a fracton phase transition
Mohammad Hossein Zarei, Mohammad Nobakht
Finding suitable indicators for characterizing quantum phase transitions plays an important role in understanding different phases of matter. It is especially important for fracton…
