Bluetooth Three‐Dimensional AOA Positioning Method Based on the AMA‐SDM
International Journal of Distributed Sensor Networks, Volume 2025, Issue 1, 2025.In order to solve the highly nonlinear nonconvex problem of the mathematical model in Bluetooth (angle of arrival (AOA)) localization, this paper proposes an alternating minimization algorithm for three‐dimensional AOA localization. The algorithm method converts the solving error minimization solving three‐dimensional coordinate problem in Bluetooth ...

Cold and Warm Denaturation of Proteins
, 2001 We introduce a simplified protein model where the water degrees of freedom appear explicitly (although in an extremely simplified fashion). Using this model we are able to recover both the warm and the cold protein denaturation within a single framework,

Scaling behavior and strain dependence of in-plane elastic properties of graphene [PDF]
, 2015 We show by atomistic simulations that, in the thermodynamic limit, the in-plane elastic moduli of graphene at finite temperature vanish with system size $ L $ as a power law $ ~ L^{-\eta_u} $ with $ \eta_u \simeq 0.325 $, in agreement with the membrane ...
