Torsional path integral Monte Carlo method for the quantum simulation of large molecules [PDF]
, 2002 A molecular application is introduced for calculating quantum statistical mechanical expectation values of large molecules at nonzero temperatures. The Torsional Path Integral Monte Carlo (TPIMC) technique applies an uncoupled winding number formalism to

Weak Forces and Neutrino Oscillations under the standards of Hybrid Gravity with Torsion
, 2013 We present a unifying approach where weak forces and neutrino oscillations are interpreted under the same standards of torsional hybrid gravity. This gravitational theory mixes metric and metric-affine formalism in presence of torsion and allows to ...

Advanced Engineering Materials, EarlyView.Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Experiment and Simulation of Self-excited Torkbuster
Shiyou jixie, 2017 The stick-slip vibration is a technical bottleneck restricting for PDC bit in efficient drilling deep hard formation. To reduce the stick-slip vibration of drill bit during drilling deep hard formations, a torkbuster has been introduced.

Behavior of Torsional Alfven Waves and Field Line Resonance on Rotating Magnetars [PDF]
, 2005 Torsional Alfven waves are likely excited with bursts in rotating magnetars. These waves are probably propagated through corotating atmospheres toward a vacuum exterior.
