Variational formulation of active nematic fluids: theory and simulation by W Mirza, A Torres-Sánchez, G Vilanova, Marino Arroyo

“…The development of thermodynamically consistent theories and numerical methods to model active nemato-hydrodynamics is eased by mathematical formalisms enabling systematic derivations and structured-preserving algorithms. Alternative to classical nonequilibrium thermodynamics and bracket formalisms, here we develop a theoretical and computational framework for active nematics based on Onsager’s variational formalism to irreversible thermodynamics, according to which the dynamics result from the minimization of a Rayleighian functional capturing the competition between free-energy release, dissipation and activity. …”

Chloroplast genome features and intraspecific variation of Rosa praelucens by WANG Qigang1, CAO Shirui1,2, WANG Huichun1, MA Changle2, YAN Huijun1, QIU Xianqin1, JING Weikun1, JIAN Hongying1*

“…These results indicate that the chloroplast genomes are highly conserved in size, sequence and structure within R. praelucens. The rich intraspecific phenotypic diversity is not caused by the variation of chloroplast genomes among different individual plants.…”

Identification of diversity-generating retroelements in host-associated and environmental genomes: prevalence, diversity, and roles by Mariela Carrasco-Villanueva, Chaoxian Wang, Chaochun Wei

“…Conclusions Our research sheds light on the widespread prevalence of DGRs within environments and taxa, and supports the DGR phylogenetic divergence in different organisms. These variations might also occur in their structures since some cassette architectures were common in specific underrepresented phyla. …”

Intraspecific Functional Trait Variation and Coordination in Schizachyrium scoparium by Jacob Zeldin, Tessa Dethlefs, Stacy Caeiro, Daniel Puga, Andrea Kramer

“…We asked (1) how regional populations of S. scoparium differ in their functional traits, (2) how functional trait variation in S. scoparium is structured among and within populations, and (3) how above‐ and below‐ground functional traits of S. scoparium coordinate and describe axes of functional trade‐offs. …”

Theoretical study on the transition wavelengths and probabilities, Landé gJ factors, and sensitivity to fundamental constants of Ge-like highly charged ions by Cunqiang Wu, Xiaobin Ding, Chenzhong Dong

“…Through an analysis on the properties of relevant ions, we find that the $M1$ and $E2$ transitions of selected HCIs exhibit suitable clock transition wavelengths, narrow natural linewidths, high quality factors, and high sensitivity to variations in the fine structure constant α . These ions hold significant potential for applications in the development of optical clocks and the investigation of potential variation of fine structure constant.…”

The third dimension of alpine plant leaf traits is related to cold-tolerance by Yuan Wang, Ji Suonan, Kun Liu, Yanni Gao, Sihao Zhu, Qian Liu, Ning Zhao

“…Furthermore, a cold resistance experiment was conducted at one of these sites to estimate the lethal temperature causing 50% frost damage (LT50) of 11 alpine species. The majority of variations in 12 leaf traits of alpine plants were captured by three trait axes, in which leaf carbon (LCC) and NSC (including leaf starch; LSC and leaf soluble sugars; LSS) were clustered in a new dimension (PC3) beyond leaf size and structure, and resource economics. …”
