A new glirid-like cricetid from the lower Oligocene of Southern China

Lu, Xiao-Yu ; Ni, Xijun ; Maridet, Olivier

In: Journal of Vertebrate Paleontology, 2021, p. e1917587

Here we report a new cricetid s.l., Caecocricetodon yani, gen. et sp. nov., discovered in the early Oligocene of the Caijiachong Formation in Yunnan Province, China. The new cricetid differs from all known cricetids or stem muroids by its particular molar pattern displaying numerous crests and spurs. Our phylogenetic analysis based on a matrix including 42 taxa and 72 characters indicates...

Pterosaurs were the first vertebrates to evolve powered flight1 and comprised one of the main evolutionary radiations in terrestrial ecosystems of the Mesozoic era (approximately 252–66 million years ago), but their origin has remained an unresolved enigma in palaeontology since the nineteenth century2,3,4. These flying reptiles have been hypothesized to be the close relatives of a wide...

Identifying prize-winning scientists by a competition-aware ranking

Zhou, Yuhao ; Wang, Ruijie ; Zeng, An ; Zhang, Yi-Cheng

In: Journal of Informetrics, 2020, vol. 14, no. 3, p. 101038

Evaluating scholars’ achievements is an important problem in the science of science with applications in the evaluation of grant proposals and promotion applications. Since the number of scholars and the number of scholarly outputs grow exponentially with time, well-designed ranking metrics that have the potential to assist in these tasks are of prime importance. To rank scholars, it is...

High-risk KPC-producing Klebsiella pneumoniae lack type I R-M systems

Zhou, Ying ; Tian, Dongxing ; Tang, Yu ; Yu, Lianhua ; Huang, Yunkun ; Li, Gang ; Li, Meng ; Wang, Yong ; Yang, Zehua ; Poirel, Laurent ; Jiang, Xiaofei

In: International Journal of Antimicrobial Agents, 2020, vol. 56, no. 2, p. 106050

Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae (KPC-KP) have disseminated worldwide and are a major threat to public health. The multidrug- resistant (MDR)-phenotype of KPC-KP are commonly associated with the presence of high molecular weight blaKPC plasmids. Restriction-modification (R-M) systems provide bacteria with innate defense against plasmids or other infectious gene...

A revision of the pelomedusoid turtle Jainemys pisdurensis from the Late Cretaceous (Maastrichtian) Lameta Formation of India

Joyce, Walter G. ; Bandyopadhyay, Saswati

In: PeerJ, 2020, vol. 8, p. e9330

Background: Jainemys pisdurensis comb. nov. is an extinct pleurodiran turtle from the Late Cretaceous (Maastrichtian) of India, previously referred to Carteremys and Shweboemys. The holotype, an eroded skull, had been collected near the village of Pisdura, south of Nagpur, in Maharashtra State, while all referred shell material originates from coeval sediments exposed at the nearby village of...

Online newspaper framing of non-communicable diseases : comparison of mainland China, Taiwan, Hong Kong and Macao

Chang, Angela ; Schulz, Peter J. ; Cheong, Angus Wenghin

In: International journal of environmental research and public health, 2020, vol. 17, no. 15, p. 15 p

As non-communicable diseases (NCDs) are now well recognized as the leading cause of mortality among adult populations worldwide, they are also increasingly the focus of media coverage. As such, the objective of this study is to describe the framing of NCDs in the coverage of newspapers, with the understanding that it says something about the society producing it. Automatic content analysis was ...

Multiscale community estimation based on temporary local balancing strategy

Zhou, Qiang ; Cai, Shi-Min ; Zhang, Yi-Cheng

In: International Journal of Modern Physics C, 2020, vol. 31, no. 04, p. 2050056

Community division in complex networks has become one of the hot topics in the field of network science. Most of the methods developed based on network topology ignore the dynamic characteristics underlying the structure. By exploring the diffusion process in the network based on random walk, this paper sums up the general rule with temporal characteristics as a temporary local balancing...
