Contractive and optimal sets in Musielak-Orlicz spaces with a smoothness condition [PDF]

open access: yesOpuscula Mathematica, 2013
In this paper we use our recent generalization of a theorem of Jamison-Kamińska-Lewicki (characterizing one-complemented subspaces in Musielak-Orlicz sequence spaces defined by Musielak-Orlicz functions satisfying a general smoothness condition) in order

Examining GDP Growth and Its Volatility: An Episodic Approach

open access: yesEntropy, 2021
In this paper, we study economic growth and its volatility from an episodic perspective. We first demonstrate the ability of the genetic algorithm to detect shifts in the volatility and levels of a given time series.

Validation of the mathematics in the anaesthetic impact calculator, a smartphone app for the calculation the CO2e of inhalational anaesthesia

open access: yesAnaesthesia, 2019
The overall volume is then the sum of the FGF and the volume of vapour added downstream of the vaporisers. Assuming that volatile anaesthetic agents behave as ideal gases and obey Avogadro’s law, the mole fraction used per hour is the volume of vapour ...
