yucatanense (USDA GRIN accession PI 501501, also called Tx2094, collected by J McD Stewart), shown in Figure 1 and identified by RFLP analysis [ 2] and morphological evidence as an excellent exemplar of truly wild (as opposed to feral) G. hirsutum.
The well-defined interactions that drive the formation of helical secondary structure, coupled with the ability to introduce chemoselective moieties for oriented immobilization, make BASE-C an excellent exemplar peptide to investigate the effect of surface immobilization and molecular crowding on molecular conformation.
An excellent exemplar of this is the Suzuki Miyaura reaction which is contingent upon chemoselective engagement of a specific boron species by a transient palladium II) intermediate.[ 3, 4] Boron solution speciation can be complex and the deliberate and chemoselective control of the equilibria associated with a mixture of boron species has, to our knowledge, not been described.
We believe that there will be a demand for molecules from CrystalEye and Quixote and that these will be excellent exemplars and workbench for crystallographers, scientists and computational scientists interested in P2P systems and distributed repositories.
Excellent exemplars demonstrated key aspects of the hidden curriculum and did not require an understanding of character or plotline.
The first exemplar, Zooniverse, is an excellent example of cohesive data policy, policy that clarifies data ownership, and policy that includes legal disclaimers.
The second exemplar, iNaturalist, is an excellent example of a cohesive data policy that sets clear guidelines for attribution and privacy permissions.
An exemplar is the excellent LAMBDA site which is a repository for data arising from research into the cosmic microwave background.
With an excellent fossil record, tyrannosaurs stand as exemplar fossil organisms in studies of dinosaur biomechanics, development, anatomy, evolution, cognition, and paleoecology3,7.
Califlora, a local project operating on a much smaller scale, is listed as a third exemplar due to its excellent attribution guidelines and clear presentation of complex privacy permissions.
Even though horse evolution has received the lion's share of the publicity, the record of rhinos, tapirs, and brontotheres is also excellent, and each deserves more frequent mention as exemplars of evolution to replace the overused examples of horse evolution.
