Cognitive decline in Sprague–Dawley rats induced by neuroplasticity changes after occlusal support loss

Xiaoyu Wang, Qian Pang, Jiangqi Hu, Bin Luo, more

CNS Neuroscience & Therapeutics > 30 > 6 > n/a - n/a

Background Tooth loss is closely related to cognitive impairment, especially affecting cognitive functions involving hippocampus. The most well‐known function of the hippocampus is learning and memory, and the mechanism behind is neuroplasticity, which strongly depends on the level of brain‐derived neurotrophic factor (BDNF). While research has delved into the possible mechanisms behind the loss...

Densification Induced Decoupling of Electrical and Thermal Properties in Free‐Standing MWCNT Films for Ultrahigh p‐ and n‐Type Power Factors and Enhanced ZT

Kuncai Li, Xu Sun, Yizhuo Wang, Jing Wang, more

Small > 19 > 52 > n/a - n/a

Generating sufficient power from waste heat is one of the most important things for thermoelectric (TE) techniques in numerous practical applications. The output power density of an organic thermoelectric generator (OTEG) is proportional to the power factors (PFs) and the electrical conductivities of organic materials. However, it is still challenging to have high PFs over 1 mW m⁻¹ K⁻² in free‐standing...

On dynamic pricing under model uncertainty

Xiaohan Zhu, Xu Sun

Naval Research Logistics (NRL) > 69 > 6 > 856 - 868

We formulate and solve a robust dynamic pricing problem for an ambiguity‐averse agent who faces an uncertain probabilistic law governing the realized demand for a single product. Specifically, the pricing problem is framed as a stochastic game that involves a maximizing player (the “agent”) and a minimizing player (“nature”) who promotes robustness by distorting the agent's beliefs within prescribed...
