She’s Vietnamese, and grew up in a small town north of Saigon. According to what Tyler has said, she immigrated to the US in 2008. Although he didn’t say what the reason was, I can assume it was for school, since she would’ve been college age at the time.

http://docs.openmm.org/latest/api-python/generated/openmm.openmm.NoseHooverIntegrator.html WebThe Nose-Hoover thermostat, or chain of thermostats, can be used as well to control the wave function temperature, i.e. the fictitious kinetic energy. This prevents drifting of the wave function from the Born-Oppenheimer PES during long simulations.

Web4 jun. 1998 · Reversible algorithms for Nosé–Hoover chain (NHC) dynamics are developed by simple extensions of Verlet-type algorithms: leap frog, position Verlet, and velocity Verlet.
