High-resolution NMR structure of an RNA model system : the 14-mer cUUCGg tetraloop hairpin RNA [PDF]

open access: yes, 2010
We present a high-resolution nuclear magnetic resonance (NMR) solution structure of a 14-mer RNA hairpin capped by cUUCGg tetraloop. This short and very stable RNA presents an important model system for the study of RNA structure and dynamics using NMR ...

Asymptotics of Wigner 3nj-symbols with Small and Large Angular Momenta: an Elementary Method

open access: yes, 2011
Yu and Littlejohn recently studied in arXiv:1104.1499 some asymptotics of Wigner symbols with some small and large angular momenta. They found that in this regime the essential information is captured by the geometry of a tetrahedron, and gave new ...

Molecular Engineering of Ionic Metal‐Organic Frameworks via Ligand Conjugation Modulation for Tailored Phosphorescence and Multilevel Encryption

open access: yesAdvanced Science, EarlyView.
This work exhibits a molecular engineering approach for efficient equilibrium phosphorescence through guest ion‐mediated ligand conjugation to modulate ionic Metal‐Organic Frameworks excited state dynamics. The designed IMOF‐DMF realizes temperature‐responsive room‐temperature phosphorescence and multi‐state lifetime encoding for anti‐counterfeiting ...

7-Chloro-2-[1-(4-methoxyphenyl)pyrazol-4-yl]-3,3-dimethyl-3H-indole

open access: yesActa Crystallographica Section E, 2010
In the title compound, C20H18ClN3O, the dihedral angle between the pyrazole and the 3H-indole components is only 13.28 (6)°, indicating that there is conjugation between the two heterocyclic subunits.

A kinematically Bifurcated Metamaterial for Integrated Logic Operation and Computing

open access: yesAdvanced Science, EarlyView.
A family of 2n‐side kinematic polygonal modules with n decoupled inputs and 2n extreme configurations via kinematic bifurcation is proposed. It allows integrating seven basic logic gates on a quadrilateral module. Moreover, a minimized Parallel Computing Sum of Products function is developed, enabling all 2‐bit arithmetic (including division ...
