Assessing Honey Bee Colony Health Using Temperature Time Series
Karina Arias-Calluari, Theotime Colin, Tanya Latty +2
Honey bees face an increasing number of stressors that disrupt the natural behaviour of colonies and, in extreme cases, can lead to their collapse. Quantifying the status and resil…
Comparative analysis of stationarity for Bitcoin and the S&P500
Yaoyue Tang, Karina Arias-Calluari, Michael S. Harré
This paper compares and contrasts stationarity between the conventional stock market and cryptocurrency. The dataset used for the analysis is the intraday price indices of the S&P5…
Stylized Facts of High-Frequency Bitcoin Time Series
Yaoyue Tang, Karina Arias-Calluari, M. N. Najafi +2
This paper analyses the high-frequency intraday Bitcoin dataset from 2019 to 2022. During this time frame, the Bitcoin market index exhibited two distinct periods, 2019-20 and 2021…
Variable order porous media equations: Application on modeling the S&P500 and Bitcoin price return
Yaoyue Tang, Fatemeh Gharari, Karina Arias-Calluari +2
This article reveals a specific category of solutions for the Variable Order (VO) nonlinear fractional Fokker-Planck equations. These solutions are formulated using VO -Ga…
Modelling daily weight variation in honey bee hives
Karina Arias-Calluari, Theotime Colin, Tanya Latty +2
A quantitative understanding of the dynamics of bee colonies is important to support global efforts to improve bee health and enhance pollination services. Traditional approaches f…
Local and Non-local Fractional Porous Media Equations
Fatemeh Gharari, Karina Arias-Calluari, Fernando Alonso-Marroquin +1
Recently it was observed that the probability distribution of the price return in S\&P500 can be modeled by -Gaussian distributions, where various phases (weak, strong super dif…
