Nanorobotic motion on solid substrates is greatly hindered by strong nanofriction, and powerful nanomotors‒the core components for nanorobotic motion‒are still lacking. Optical actuation addresses power and motion con...

This paper puts forth a new metric, dubbed channel cycle time (CCT), to measure the short-term fairness of Communication networks. CCT characterizes the average duration between two consecutive successful transmissions of a user, during which all other users successfully accessed the channel at least once. In contrast to existing short-term fairness measures, CCT provides more comprehensive insight into the transient dynamics of communication networks, with a particular focus on users' delays and jitter. To validate the efficacy of our approach, we analytically characterize the CCTs for two classical commu-nication protocols: slotted Aloha and CSMA/CA. The analysis demonstrates that CSMA/CA exhibits superior short-term fairness over slotted Aloha. Beyond its role as a measurement metric, CCT has broader implications as a guiding principle for the design of future communication networks by emphasizing factors like fairness, delay, and jitter in short-term behaviors.

The importance of topological spin textures(TSTs), such as skyrmions, merons, hopfions, etc., is due to their static and dynamic properties [1]. They carry a topological number that characterizes the homotopy group Π_(n)(S^(2))(n ∈ Z) and classifies maps from S^(n) to S^(2)(e.g., the skyrmion winding number corresponds to Π_(2)(S^(2))).

For the first time, we report the design and fabrication of a steep-slope negative quantum capacitance field-effect transistor (NQCFET) with a single-layer (SL)-graphene encapsulated in the gate stack of a MoS 2 FET. Subthermionic steep switching is achieved with a minimum subthreshold slope (SS) of 31 mV/dec with negligible hysteresis. The contribution of negative quantum capacitance from the low density of states in the electron system in SL-graphene has been experimentally and theoretically explored.
