WebFeb 8, 2024 · In this study, we propose a deep fused model (DFM) that considers subject detection and predicate matching as two related and complementary sub-tasks. Specifically, we extract the subject entity in a question using the SDM, and learn semantic vector representations for questions and predicates using a multilevel semantic model (MLSM). Web) The magnitude of the Lorentz force F is F = qvB sinθ, where θ is the smallest angle between the directions of the vectors v and B. If v and B are parallel or anti-parallel to each other, then sinθ = 0 and F = 0. If v and B are perpendicular to each other, then sinθ = 1 and F has its maximum possible magnitude F = qvB.
