Reduced-order autoregressive dynamics of a complex financial system: a PCA-based approach
Pouriya Khalilian, Sara Azizi, Mohammad Hossein Amiri +1
This study analyzes the dynamic interactions among the NASDAQ index, crude oil, gold, and the US dollar using a reduced-order modeling approach. Time-delay embedding and principal…
On the Merger Rate of Primordial Black Holes in Cosmic Voids
Saeed Fakhry, Seyed Sajad Tabasi, Javad T. Firouzjaee
Cosmic voids are known as underdense substructures of the cosmic web that cover a large volume of the Universe. It is known that cosmic voids contain a small number of dark matter…
The Merger Rate of Primordial Black Hole-Neutron Star Binaries in Ellipsoidal-Collapse Dark Matter Halo Models
Saeed Fakhry, Zahra Salehnia, Azin Shirmohammadi +1
Primordial black holes (PBHs), as a potential macroscopic candidate for dark matter, can encounter other compact objects in dark matter halos because of their random distribution.…
New Accretion Constraint on the Evaporation of Primordial Black Holes
Seyed Sajad Tabas, Mahsa Berahman, Javad T. Firouzjaee
In this paper, we have investigated the processes of evaporation and accretion of primordial black holes during the radiation-dominated era and the matter-dominated era. This subje…
A Survey of Strong Cosmic Censorship Conjecture Beyond Einstein's Gravity
Mohsen Khodadi, Javad T. Firouzjaee
The strong cosmic censorship conjecture (SCCC) proposed by Penrose states that the presence of the inner Cauchy horizon () in the black hole solutions does not threat…
The Integrated Sachs-Wolfe Effect in Interacting Dark Matter-Dark Energy Models
Mina Ghodsi Yengejeh, Saeed Fakhry, Javad T. Firouzjaee +1
Interacting dark matter-dark energy (IDMDE) models can be taken to account as one of the present challenges that may affect the cosmic structures. In this work, we study the integr…
Hawking Temperature for 4D-Einstein-Gauss-Bonnet Black Holes from uncertainty principle
Sara Azizi, Sareh Eslamzadeh, Javad T. Firouzjaee +1
Inspired by string theory, Heisenberg's uncertainty principle can be generalized to include the photon-electron gravitational interaction, which leads to the Generalized Uncertaint…
Machine learning model to project the impact of Ukraine crisis
Javad T. Firouzjaee, Pouriya Khaliliyan
Russia's attack on Ukraine on Thursday 24 February 2022 hitched financial markets and the increased geopolitical crisis. In this paper, we select some main economic indexes, such a…
The Interpretability of LSTM Models for Predicting Oil Company Stocks: Impact of Correlated Features
Javad T. Firouzjaee, Pouriya Khaliliyan
Oil companies are among the largest companies in the world whose economic indicators in the global stock market have a great impact on the world economy\cite{ec00} and market due t…
