FIGURE 1 in Extended Descriptions and Revised Diagnoses of Three Recently Described, Little-Known Mountain Dragons (Reptilia: Agamidae: Diploderma) from the Yalong River Valley in Southwest China
FIGURE 1. Phylogenetic relationships among members of the genus Diploderma inferred using mitochondrial ND2 gene (1032 bp). Three types of nodal supports (Bayesian posterior probability / SH-aLRT test / ultrafast bootstrap) are mapped onto the topology from Bayesian Inference analyses, where "–" indicate low support. Supports of nodes with all three support values below the threshold values (0.95, 80, 95 for Bayesian posterior probability, SH-aLRT test, and ultrafast bootstrap, respectively) are not displayed on the tree. Terminal nodes that unify each recognized species are all strongly supported. GenBank accession numbers of newly collected specimens are shown in bold. Photos by Wenjie Dong, Ling Li, and Kai Wang.

Strain fingerpringting of exciton valley character in 2D semiconductors
<p>Raw data which are used to generate the figures in the publication 'Strain fingerpringting of exciton valley character in 2D semiconductors'.</p> <p>Abstract of the paper:</p> <p>Intervalley excitons with electron and hole wavefunctions residing in different valleys determine the long-range transport and dynamics observed in many semiconductors. However, these excitons with vanishing oscillator strength do not directly couple to light and, hence, remain largely unstudied. Here, we develop a simple nanomechanical technique to control the energy hierarchy of valleys via their contrasting response to mechanical strain. We use our technique to discover previously inaccessible intervalley excitons associated with K, Γ, or Q valleys in prototypical 2D semiconductors WSe2 and WS2. We also demonstrate a new brightening mechanism, rendering an otherwise “dark” intervalley exciton visible via strain-controlled hybridization with an intravalley exciton. Moreover, we classify various localized excitons from their distinct strain response and achieve large tuning of their energy. Overall, our valley engineering approach establishes a new way to identify intervalley excitons and control their interactions in a diverse class of 2D systems.</p>
