Living with fibrodysplasia ossificans progressiva: radiological images of a patient with extensive heterotopic ossification by Mohammed Mostafa Kotb, Omar, Usama Farghaly, Kaliya-Perumal, Arun-Kumar

“…Radiographic evaluation with X-rays and CT scans revealed scoliosis and total fusion of almost all levels of the spine, with only a few disc spaces spared. A large mass of heterotopic bone was observed, corresponding to the location of the paraspinal muscles in the lumbar region, branching upwards and fusing with the scapulae on both sides. …”

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. …”

Biothermoplastic elastomer (BTPE), influence of architecture on mechanical properties by Tjin, Monica Suryana.

“…Biodegradable thermoplastic elastomer was acquired by synthesizing four-armed and three-armed star-shaped copolymers via ring-opening polymerization with multifunctional initiator, such as pentaerythritol and glycerol, using stannous octoate (SnOct2) catalyst in bulk at 130oC. …”
