Over time, during the existence of a company, there are inevitable changes Necklaces, Ready-to-Wear,Beads in its organizational structure, normal changes caused by the increase or decrease of its activity volume, changes brought about by the adaptation to the new needs of the market.Concretely, the company can move from organizational systems such
Dynamic manipulation of wavefront is vital for massive free-space optical applications.Here we propose a set of largely tunable circular polarization splitters leveraging graphene nanoantennas with high efficiency reaching 83% and wide frequency tunability range of 2 to 5 THz.By synergizing the electrically tunable surface plasmons of graphene with
The frequent occurrence of major earthquakes highlights the structural challenges posed by long-period ground motions (LPGMs).This study investigates the seismic performance and resilience of five reinforced concrete (RC) columns with Journal different high-strength steel bars under LPGM-induced cyclic loading, both experimentally and numerically.T
