Exotic Spectra and Lattice Vibrations of Ice X Using the DFT Method.

A typical vibrational spectrum in the ice phase has four separate bands: Translation, libration, bending, and stretching. Ice X, the final ice phase under high pressure, shows an exotic vibrational spectrum. Based on harmonic approximation, an ideal crystal of ice X has one peak, at 998 cm, for Raman scattering and two peaks, at 450 cm and 1507 cm, for infrared absorption in this work.

Non-concomitant cortical structural and functional alterations in sensorimotor areas following incomplete spinal cord injury.

Brain plasticity, including anatomical changes and functional reorganization, is the physiological basis of functional recovery after spinal cord injury (SCI). The correlation between brain anatomical changes and functional reorganization after SCI is unclear. This study aimed to explore whether alterations of cortical structure and network function are concomitant in sensorimotor areas after incomplete SCI.
