Infusing epistemic perspectives on scientific practices in science teacher education by Erduran, S, Saribas, D, Kaya, E

“…The depiction of scientific practices relies on a theoretical model called the Benzene Ring Heuristic (BRH) which consolidates the epistemic, cognitive and social aspects of scientific practices into a holistic and visual representation. …”

Hand-held devices for generating force/torque perturbations by Wong, Yoke Cung.

“…The working principle is to spin the flywheel at a certain angular speed and then break this rotation motion within a very short period so that relatively high deceleration will take place and torque will be generated. …”

Topological phases with parafermions: theory and blueprints by Alicea, J, Fendley, P

“…First we generalize the intimate connection between the -symmetric Ising quantum spin chain and Majorana fermions to -symmetric chains and parafermions. …”

Gender equality, growth, and how a technological trap destroyed female work by Humphries, J, Schneider, B

“…We then explain how a crucial example of technological unemployment for women—the destruction of hand spinning during the British Industrial Revolution—contributed to the emergence of the male breadwinner family. …”

Chiral Modes at Exceptional Points in Exciton-Polariton Quantum Fluids by Gao, T., Li, G., Estrecho, E., Liew, Timothy Chi Hin, Comber-Todd, D., Nalitov, A., Steger, M., West, K., Pfeiffer, L., Snoke, D. W., Kavokin, A. V., Truscott, A. G., Ostrovskaya, E. A.

“…In particular, a vortex is generated by driving two dipole modes of the non-Hermitian ring resonator into degeneracy. Transition through the exceptional point in the space of the system’s parameters is enabled by precise manipulation of real and imaginary parts of the closed-wall potential forming the resonator. …”
