Photonics, 2022 In optical wireless power transmission (OWPT) systems, since beam size is finite, and relative position and attitude between transmitter and receiver is not always stationary, both beam alignment and shaping accuracies are important parameters.

Reheating in R2 Palatini inflationary models [PDF]
Physical Review D, 2019 We consider $R^2$ inflation in the Palatini gravity assuming the existence of scalar fields, coupled to gravity in the most general manner. These theories, in the Einstein frame, and for one scalar field $h$, share common features with $K$ - inflation ...

Photonics, 2022 Since optical wireless power transmission (OWPT) transmits power by light, which has a narrow diffraction angle feature, it is a strong candidate for wireless power transmission systems supporting long ranges.

Minimal Higgs inflation with an R2 term in Palatini gravity [PDF]
Physical Review D, 2019 It has recently been suggested that the Standard Model Higgs boson could act as the inflaton while minimally coupled to gravity - given that the gravity sector is extended with an $\alpha R^2$ term and the underlying theory of gravity is of Palatini ...

Beware of R2: simple, unambiguous assessment of the prediction accuracy of QSAR and QSPR models
Journal of Chemical Information and Modeling, 2015 The statistical metrics used to characterize the external predictivity of a model, i.e., how well it predicts the properties of an independent test set, have proliferated over the past decade.
