Prompt Engineering Through the Lens of Optimal Control

Autor: Luo, Yifan, Tang, Yiming, Shen, Chengfeng, Zhou, Zhennan, Dong, Bin

Prompt Engineering (PE) has emerged as a critical technique for guiding Large Language Models (LLMs) in solving intricate tasks. Its importance is highlighted by its potential to significantly enhance the efficiency and effectiveness of human-machine

Fictitious Play via Finite Differences for Mean Field Games with Optimal Stopping

Autor: Shen, Chengfeng, Luo, Yifan, Zhou, Zhennan

This paper considers mean field games with optimal stopping time (OSMFGs) where agents make optimal exit decisions, the coupled obstacle and Fokker-Planck equations in such models pose challenges versus classic MFGs. This paper proposes a generalized

Tumor growth with a necrotic core as an obstacle problem in pressure

Autor: Dou, Xu'an, Shen, Chengfeng, Zhou, Zhennan

Motivated by the incompressible limit of a cell density model, we propose a free boundary tumor growth model where the pressure satisfies an obstacle problem on an evolving domain $\Omega(t)$, and the coincidence set $\Lambda(t)$ captures the emergin

Hyperhomocysteinemia is a result, rather than a cause, of depression under chronic stress.

Autor: Shen Chengfeng, Liu Wei, Wang Xinxing, Wu Lei, Zhan Rui, Qian Lingjia

Publikováno v: PLoS ONE, Vol 9, Iss 10, p e106625 (2014)

BACKGROUND: Although the accumulation of homocysteine (Hcy) has been implicated in the pathogenesis of depression, whether Hcy is directly involved and acts as the primary cause of depressive symptoms remains unclear. The present study was designed t
