 Financial portfolio management aims to allocate resources for optimal returns while mitigating risk. Traditional methods based on assumptions like normal return distributions and simplistic risk measures have limitations. Deep reinforcement learning (DRL) combines deep learning for feature representation and reinforcement learning for optimal...

 The study examines the relationship between oil prices and headline and core inflation in Saudi Arabia from 2001 to 2022. To examine short- and long-run dynamic effects, the study employs Johansen cointegration and Vector Error Correction Model (VECM) approach. Our findings indicate the presence of long run equilibrium relationship only in th...

 This paper presents one algorithm for choosing optimal solution from a bivariant time series database. The presented algorithm uses a similarity measure to compare each object in the database to a specific suitable object. The proposed method is useful when dealing with multidimensional time series data, e.g., bi-variant time series, where c...

 This research focuses on the dynamics of electron behavior during the laserinduced breakdown (LIB) in skin tissues, pivotal for plasma generation in biomedical contexts. Through a numerical analysis centered on high-intensity Nd:YAG laser pulses within the 500–1000 nm wavelength range and a 10 ns pulse duration, we explore the balance ...
