Deciphering trophic interactions in a mid-Cambrian assemblage.

iScience 2021 Apr 4;24(4):102271. Epub 2021 Mar 4.

Department of Biology, University of Maryland, College Park, MD 20742, USA.

Exceptionally preserved fossil sites have allowed specimen-based identification of trophic interactions to which network analyses have been applied. However, network analyses of the fossil record suffer from incomplete and indirect data, time averaging that obscures species coexistence, and biases in preservation. Here, we present a high-resolution fossil data set from Raymond Quarry member of the mid-Cambrian Burgess Shale (7,549 specimens, 61 taxa, ∼510 Mya) and formulate a measure of "preservation bias" that aids identification of assemblage subsets to which network analyses can be reliably applied.

Storytelling on Oral Grounds: Viewpoint Alignment and Perspective Taking in Narrative Discourse.

Front Psychol 2021 4;12:634930. Epub 2021 Mar 4.

Centre for Language Studies, Radboud University Nijmegen, Nijmegen, Netherlands.

In this paper, we seek to explain the power of perspective taking in narrative discourse by turning to research on the oral foundations of storytelling in human communication and language. We argue that narratives function through a central process of alignment between the viewpoints of narrator, hearer/reader, and character and develop an analytical framework that is capable of generating general claims about the processes and outcomes of narrative discourse while flexibly accounting for the great linguistic variability both across and within stories. The central propositions of this viewpoint alignment framework are that the distance between the viewpoints of participants in the narrative construal - narrator, character, reader - is dynamic and regulated by linguistic choices as well as contextual factors.

Braz J Med Biol Res 2021 15;54(5):e10274. Epub 2021 Mar 15.

College of Life Sciences, Qufu Normal University, Qufu, Shandong, China.

Prolactin (PRL) plays critical roles in regulation of biological functions with the binding of specific prolactin receptor (PRLR). Revealing the expression patterns of PRLR at different developmental stages is beneficial to better understand the role of PRL and its mechanism of action in striped hamsters. In this study, the cDNA sequence of PRLR (2866-base-pairs) was harvested from the pituitary of mature female striped hamsters (Cricetulus barabensis) that contains an 834-base-pair 5'-untranslated region (1-834 bp), a 1848-base-pair open reading frame (835-2682 bp), and a 184-base-pair 3'-untranslated region (2683-2866).

What Dominates the Female Class Identification? Evidence From China.

Front Psychol 2021 22;12:627610. Epub 2021 Feb 22.

Key Laboratory of Urban Land Resources Monitoring and Simulation, MNR, Shenzhen, China.

In advocating gender equality today, we should not only pay attention to women's social status but also call for the women's psychological identification of class equality. What dominates female class identification? To answer this question, based on the data of the Chinese General Social Survey (CGSS) in 2015, this study constructs a female class identity framework from five aspects: the mother's intergenerational influence, female personal characteristics, lifestyle, gender consciousness, and spouse status. In this study, the ordered logit model is used to empirically analyze the impact of various factors on female class identification, and the results show the following: (1) gender consciousness has a significant impact on female class identification.

Torsional Characteristics of Carbon Nanotubes: Micropolar Elasticity Models and Molecular Dynamics Simulation.

Nanomaterials (Basel) 2021 Feb 11;11(2). Epub 2021 Feb 11.

School of Mechanical Engineering, Shiraz University, Shiraz 71963-16548, Iran.

Efficient application of carbon nanotubes (CNTs) in nano-devices and nano-materials requires comprehensive understanding of their mechanical properties. As observations suggest size dependent behaviour, non-classical theories preserving the memory of body's internal structure via additional material parameters offer great potential when a continuum modelling is to be preferred. In the present study, micropolar theory of elasticity is adopted due to its peculiar character allowing for incorporation of scale effects through additional kinematic descriptors and work-conjugated stress measures.

Lipid Mixing Assay for Murine Myoblast Fusion and Other Slow Cell-cell Fusion Processes.

Bio Protoc 2020 Mar 5;10(5):e3544. Epub 2020 Mar 5.

Section on Membrane Biology, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health, Bethesda, MD 20892, USA.

Lipid mixing (redistribution of lipid probes between fusing membranes) has been widely used to study early stages of relatively fast viral and intracellular fusion processes that take seconds to minutes. Lipid mixing assays are especially important for identification of hemifusion intermediates operationally defined as lipid mixing without content mixing. Due to unsynchronized character and the slow rate of the differentiation processes that prime the cells for cell-cell fusion processes in myogenesis, osteoclastogenesis and placentogenesis, these fusions take days.
