Piecewise-linear embeddings of the space of 3D lattices into $\RR^{13}$ for high-throughput handling of lattice parameters
Ryoko Oishi-Tomiyasu
We present two methods to continuously and piecewise-linearly parametrize rank-3 lattices by vectors of $\RR^{13}$, which provides an efficient way to judge if two sets of paramete…

Crystalline Water Structure in Room-Temperature Clathrate State: Hydrogen-Bonded Pentagonal Rings
Ching-Hsiu Chen, Wei-Hao Hsu, Ryoko Oishi-Tomiyasu +3
Water hydrogen bonding is extremely versatile; approximately 20 ice structures and several types of clathrate hydrate structures have been identified. These crystalline water struc…
