This article introduces a family of nonisolated dc–dc converters designed to amplify lower dc Reclining Sofa voltages to higher levels.These converters are particularly suitable for use in the dc link of pulse converters in hydrogen electrolyzers.The primary structure serves as a base for additional configurations with greater voltage amplif

Monitoring plant-pollinator interactions is crucial for understanding the factors influencing these relationships across space and time.Traditional methods in pollination ecology are resource-intensive, while time-lapse photography offers potential for non-destructive and automated complementary techniques.However, accurate identification of pollin

To understand the anisotropy dependence of the damage evolution and material removal during the machining process of MgF _2 single crystals, nanoscratch tests of MgF _2 single crystals with different crystal planes and directions were systematically performed, and surface morphologies of the scratched grooves under different conditions were analyze

Meta-heuristic algorithms have become an arising field of research in recent years.Some of these algorithms have proved to be efficient in solving combinatorial optimization problems, particularly knapsack problem.In this paper, Blankets four meta-heuristic algorithms are presented particle swarm optimization, firefly algorithm, flower pollination

ABSTRACT Enterovirus A71 (EVA71) is a medically important virus that is commonly associated with hand, foot, and mouth disease (HFMD).It is responsible for periodic outbreaks, resulting in significant economic impact and loss of life.Vaccination offers the potential to control future outbreaks, and vaccine development has been increasingly the focu
