Tetrapartite entanglement features of W-Class state in uniform acceleration

2019 · Frontiers of Physics

Using the single-mode approximation, we first calculate entanglement measures such as negativity (1–3 and 1–1 tangles) and von Neumann entropy for a tetrapartite W-Class system in noninertial frame and then analyze the whole entanglement measures, …

Incorporating Explicit Knowledge in Pre-trained Language Models for Passage Re-ranking

2022 · arXiv (Cornell University)

Passage re-ranking is to obtain a permutation over the candidate passage set from retrieval stage. Re-rankers have been boomed by Pre-trained Language Models (PLMs) due to their overwhelming advantages in natural language understanding. However, existing …
