Hysteresis Phenomenon in the Galloping of the D-Shape Iced Conductor [PDF]
Mathematical Problems in Engineering, 2013 It is well known that there is a hysteresis phenomenon in the amplitude variation in the iced conductor galloping with the wind velocity, which will have more obvious disadvantages to the overhead transmission lines. But hysteresis characteristics in the conductor galloping have not received much attention.

Meta‐Virtuality: Strategies of Disembeddedness in Virtual Interiorities
Journal of Interior Design, EarlyView., 2022 ABSTRACT To reclaim their seat in the rapidly growing market of virtual space, designers of the built environment can benefit from reevaluating theories that see the virtual as a mere extension/reflection of the physical. By claiming ontological autonomy from external worlds, the virtual is liberated from the hegemonic control of the physical.
