A Study of Liangzhu Period Chinese Bayberry ( Myrica rubra ) Remains from the Shi’ao Site

Shuzhi Wang, Yifan Zhao, Yonglei Wang, Hao Wang et autres

Abstract This study uses AMS radiocarbon dating (AMS 14 C), wood anatomical analysis, and pyrolysis/ gas chromatography–mass spectrometry (Py/GC–MS) to examine tree remains unearthed at the Shi’ao site in Yuyao, Zhejiang. The results identify the remains as Chinese bayberry ( Myrica rubra …

Charcoal evidence for environmental change ca. 3.5 ka and its influence on ancient people in the West Liao River Basin of northeastern China

Xin Shan Jia, Shuzhi Wang, Yonggang Sun, Yiyin Li et autres

Abstract Fossil charcoals from archaeological sites provide direct evidence for the relationship between environmental change and ancient peoples’ livelihoods in the past. Our identification of 5811 fossil charcoal fragments from 84 samples suggested temperate deciduous and mixed conifer-broadleaved forests as the dominant …

Unveiling the Superconducting Mechanism of Ba0.51K0.49BiO3

Chenhaoping Wen, Haishui Xu, Qi Yao, Rui Peng et autres

The mechanism of high superconducting transition temperatures (T_{c}) in bismuthates remains under debate despite more than 30 years of extensive research. Our angle-resolved photoemission spectroscopy studies on Ba_{0.51}K_{0.49}BiO_{3} reveal an unexpectedly 34% larger bandwidth than in conventional density functional theory calculations. This …

Collective vortex pinning and crossover between second order to first order transition in optimally doped Ba1-xKxBiO3 single crystals

Yanjing Jiao, Cheng Wang, Qiang Deng, Huan Yang et autres

Measurements on magnetization and relaxation have been carried out on an optimally doped Ba$_{0.59}$K$_{0.47}$BiO$_{3+δ}$ single crystal with $T_c$ = 31.3 K. Detailed analysis is undertaken on the data. Both the dynamical relaxation and conventional relaxation have been measured leading to the self-consistent …
