Hydrodynamic Features of Two-Phase Oil–Gas Flow in Pipelines

The results of the experiments on the transport process of fluid flow through a pipeline under temperature gradient conditions between the internal and external environments, and on continuous gas generation at the contact boundary of the transported media, are presented in this...

Quantum approximate optimization algorithm with fixed number of parameters

We introduce a novel quantum optimization paradigm: the Fixed-Parameter-Count Quantum Approximate Optimization Algorithm (FPC-QAOA). It is a scalable variational framework that maintains a constant number of trainable parameters regardless of the number of qubits, Hamiltonian com...

Bioactive Properties and Pharmaceutical Potential of New World Mistletoes of the Genus Tristerix: A Review

Mistletoes of the genus Tristerix, native to South America, represent a unique group of mostly hemiparasitic plants with potential medicinal applications. This review synthesizes existing knowledge on their biological and phytochemical properties, focusing on three main species e...

Impact of Spatial Knowledge on Fire Evacuation Performance in Large Buildings: An Integrated Simulation Approach

This study examines human evacuation performance in complex building environments under highly uncertain fire conditions, with a focus on how spatial knowledge and decision-making strategies influence exposure to hazardous conditions during emergencies in smart building contexts....

Seismic behaviour of aggregated reinforced masonry dwellings considering the combined influence of diaphragm stiffness and height irregularity

Abstract Aggregate dwellings are a common construction configuration in urban environments in the Americas, where space constraints favour terraced construction. However, seismic interaction between adjacent dwellings can significantly alter their structural response, especially...

Association of breakfast frequency with blood pressure, waist circumference, physical activity, and sedentary behavior among Brazilian adolescents

To analyze the association of breakfast frequency with cardiovascular risk factors (blood pressure and waist circumference) and physical activity and sedentary behavior in adolescents. The sample consisted of 941 Brazilian adolescents (520 girls), aged 10–17 years. Anthropometric...
