iTD3-CLN: learn to navigate in dynamic scene through Deep Reinforcement Learning by Jiang, Haoge, Esfahani, Mahdi Abolfazli, Wu, Keyu, Wan, Kong-wah, Heng, Kuan-kian, Wang, Han, Jiang, Xudong

“…In contrast to the conventional methods such as the DWA, our approach is found superior in the following ways: no need for prior knowledge of the environment and metric map, lower reliance on an accurate sensor, learning emergent behavior in dynamic scene that is intuitive, and more remarkably, able to transfer to the real robot without further fine-tuning. Our extensive studies show that in comparison to the original TD3, the proposed approach can obtain approximately 50% reduction in training to get same performance, 50% higher accumulated reward, and 30–50% increase in generalization performance when tested in unseen environments. …”

Temperature dependence of elastocaloric effect in a microstructurally graded NiTi alloy by Chen, Junyu, Wang, Wenqiang, Zhang, Qi, Lei, Liping, Ramamurty, Upadrasta, Fang, Gang

“…Detailed analyses show that while the fine grains present in the core of NiTi sheets reduce the global martensitic autocatalytic nucleation potency and increase strength to broaden Tspan, the coarser grains near the surfaces accommodate interlayer deformation to improve |ΔTad|. …”

Ultra wideBand indoor position localizaiton by Xu, Jun

“…Thus we develop an angle-of-arrival (AOA) cooperative positioning algorithm which takes advantage of high connectivity of wireless networks as well as the fine temporal resolution of UWB technique. Both TDOA and AOA ranging schemes have their own advantages and drawbacks, and thus we propose hybrid methods. …”

Negative density dependence promotes persistence of a globally rare yet locally abundant plant species Oenothera coloradensis by Stears, AE, Heidel, B, Paniw, M, Salguero-Gómez, R, Laughlin, DC

“…Consequently, several mechanisms have been proposed to explain their persistence, including negative density dependence, demographic compensation, vital rate buffering, asynchronous responses of subpopulations to environmental heterogeneity, and fine-scale source-sink dynamics. Persistence of seeds in a seed bank, which is often ignored in models of population dynamics, can also buffer small populations against collapse. …”
