Main outcome measures were depression, anxiety and perceived stress measured using validated scales. The χ² and t tests were used to assess differences between groups. Univariable and multivariable regression were performed to determine factors contributing to each outcome. Results: Women reporting PCOS, compared with women not reporting PCOS, reported higher prevalence of depression (27.3% v. 18.8%), anxiety symptoms (50% v. 39.2%) and greater score for perceived stress (1.01 ± 0.03 v. 0.88 ± 0.01). After adjusting for body mass index, infertility and socio-demographic factors, women with PCOS were still more likely to be depressed, anxious and to have a higher level of perceived stress. There was a high-level mediation effect of stress between PCOS and both depression and anxiety. Conclusion: Compared with women not reporting PCOS, women reporting PCOS have increased depression, anxiety and perceived stress. Stress may play a role in the association between PCOS, depression and anxiety. Further studies should consider assessment and management of stress in PCOS as it may be relevant for understanding the aetiology and treatment of psychological distress.]]> Tue 16 Aug 2022 10:54:17 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39110 kⁿ, where k is the base of the Mahler function, as well as some applications concerning transcendence and algebraic independence. For example, we show that the generating function of the Thue–Morse sequence and any Mahler function (to the same base) which has a nonzero Mahler eigenvalue are algebraically independent over C(z). Finally, we discuss asymptotic bounds towards generic points on the unit circle.]]> Tue 10 May 2022 14:26:34 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46279 Mon 14 Nov 2022 15:35:09 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37033 θ, the mean dissipation rate of θ̅²/2, where θ̅² is the temperature variance. The analytical approach follows that of Thiesset et al. (J. Fluid Mech., vol. 748, 2014, R2) who developed an expression for ϵ_κ, the mean turbulent kinetic energy dissipation rate, using the transport equation for (δu)², the second-order velocity structure function. Experimental data show that complete self-preservation for all scales of motion is very well satisfied along the jet axis for streamwise distances larger than approximately 30 times the nozzle diameter. This validation of the analytical results is of particular interest as it provides justification and confidence in the analytical derivation of power laws representing the streamwise evolution of different physical quantities along the axis, such as: η, λ, λθ, R_U, R_Θ (all representing characteristic length scales), the mean temperature excess Θ₀, the mixed velocity–temperature moments uθ², vθ² and θ² and ∈_θ. Simple models are proposed for uθ² and vθ² in order to derive an analytical expression for A_∈θ, the prefactor of the power law describing the streamwise evolution of ∈θ. Further, expressions are also derived for the turbulent Péclet number and the thermal-to-mechanical time scale ratio. These expressions involve global parameters that are most likely to be influenced by the initial and/or boundary conditions and are therefore expected to be flow dependent.]]> Fri 07 Aug 2020 10:22:14 AEST ]]>
