International Journal for Numerical Methods in Fluids, EarlyView.We introduce new efficient and accurate first order finite volume‐type numerical schemes, for the non‐conservative one‐dimensional blood flow equations with transport, taking into account different velocity profiles. The framework is the flux‐vector splitting approach of Toro and Vázquez‐Cendón (2012), that splits the system in two subsystems of PDEs ...

International Journal for Numerical Methods in Fluids, EarlyView.This study presents an efficient method to compute polymer stress‐tensor components in viscoelastic laminar jet flows using models such as Oldroyd‐B, Giesekus, PTT, and FENE. By assuming a stationary and parallel flow, the methodology significantly reduces computational cost.

Coherent Forecasting of Realized Volatility
Journal of Forecasting, EarlyView.ABSTRACT The QLIKE loss function is the stylized favorite of the literature on volatility forecasting when it comes to out‐of‐sample evaluation and the state of the art model for realized volatility (RV) forecasting is the HAR model, which minimizes the squared error loss for in‐sample estimation of the parameters.

Doubtful Receivables' Risk and Its Impact on Stock Returns
Journal of Corporate Accounting &Finance, EarlyView.ABSTRACT The current research proposes a previously unknown source of risk in relation to companies’ doubtful receivables. Higher relative doubtful receivables present a risk for companies' future cash flows. Hence, the article discusses an innovative risk measure associated with companies’ doubtful receivables.

International Journal of Robust and Nonlinear Control, EarlyView., 2023 Abstract We propose a hierarchical energy management scheme for aggregating Distributed Energy Resources (DERs) for grid flexibility services. To prevent a direct participation of numerous prosumers in the wholesale electricity market, aggregators, as self‐interest agents in our scheme, incentivize prosumers to provide flexibility. We firstly model the

Strategic Change, EarlyView.ABSTRACT This study examines gender disparities in mobile money (MOMO) adoption in Sub‐Saharan Africa (SSA), focusing on how National Financial Inclusion Strategies (NFIS) interact with gender‐based policies on entrepreneurship, mobility, marriage, parenthood, and asset ownership. Using fuzzy‐set qualitative comparative analysis across 16 SSA countries,

Evolutionary dynamics on a regular networked structured and unstructured multi‐population
International Journal of Robust and Nonlinear Control, EarlyView., 2023 Abstract In this paper, we study collective decision‐making in a multi‐population framework, where groups of individuals represent whole populations that interact by means of a regular network. Each group consists of a number of players and every player can choose between two options.
