4. Materials and Methods 4.1. Experimental DesignMice were divided into three groups: the Naïve group, the PBS+ONC group, and the TUDCA+ONC group. The Naïve group (12 mice) received no treatments. The PBS+ONC group (16 mice) received intraperitoneal (i.p.) injections of phosphate-buffered saline (PBS) and underwent unilateral optic nerve crush (ONC) surgery. The TUDCA + ONC group (15 mice) received i.p. injections of tauroursodeoxycholic acid (TUDCA) followed by unilateral ONC surgery.

AbstractTwo-dimensional (2D) materials such as graphene and transition metal dichalcogenides (TMDC) have received extensive research interests and investigations in the past decade. In this research, we report the first experimental measurement of the in-plane thermal conductivity of MoS2 monolayer under a large mechanical strain using optothermal Raman technique.

Previous studies have left a significant gap in researching the relationships among affective variables, cognitive factors, and learning outcomes in second language (L2) writing. To fill in this research gap, the present study set out to unveil the relationships between L2 writers’ cognitive load, anxiety, and writing performance. A total of 197 Grade 12 students from a Chinese public high school were recruited. Participants were required to complete a story continuation writing task (SCWT), the L2 Writing Cognitive Load Scale, and the L2 Writing Anxiety Scale. Structural equation modeling showed that: 1) L2 learners’ cognitive load had a direct effect on writing anxiety which in turn directly impacted SCWT performance; 2) L2 writing anxiety fully mediated the effect of cognitive load on SCWT performance; and 3) Cognitive load mainly influenced cognitive anxiety, a subcomponent of writing anxiety. The implications of the findings for L2 teaching and learning are discussed.
