Computational rheometry of yielding and viscoplastic flow in vane-and-cup rheometer fixtures by Chaparian, Emad, Owens, Crystal E., McKinley, Gareth H.

“…This results in the shearing of an almost-circular ring of viscoplastic fluid that is indistinguishable from the annular ring of fluid deformed around a slip-free rotating cylindrical bob and leads to more accurate rheometric measurements of the material flow curve. …”

Synthesis and characterization of a novel biodegradable polylactide. by Cheong, Qi Li.

“…Three-arm and four-arm star-shaped poly(DL-Lactide) (PLA) oligomers were successfully synthesized using glycerol and pentaerythritol initiator with 4-dimethylaminopyridine (DMAP) organocatalysts by ring-opening polymerization (ROP) in bulk. A series of crosslinked PLA samples were prepared using different reaction conditions and purification techniques. …”

Spontaneous symmetry breaking of an optical polarization state in a polarization-selective nonlinear reson by Manannikov, K, Mironova, E, Poliakov, A, Mikhaylov, A, Ulanov, A, Lvovsky, A

“…We pump the vapor cell with horizontally polarized light while the vertical polarization, which is initially in the vacuum state, is resonated in a ring cavity. Microscopic field fluctuations in this mode experience cumulative gain due to the compound action of amplification due to the self-rotation and feedback through the resonator, eventually acquiring a macroscopic magnitude akin to an optical parametric oscillator. …”
