A Note on the Asymptotic Expansion of a Ratio of Gamma Functions [PDF]
Proceedings of the Edinburgh Mathematical Society, 1966 Many problems in mathematical analysis require a knowledge of the asymptotic behaviour of Γ(z + α)/Γ(z + β) for large values of |z|, where α and β are bounded quantities. Tricomi and Erdélyi in (1), gave the asymptotic expansionwhere the are the generalised Bernoulli polynomials, see (2), defined byIn this note, we show that if, instead of considering

Confined axisymmetric laminar jets with large expansion ratios [PDF]
Journal of Fluid Mechanics, 2002 This paper investigates the steady round laminar jet discharging into a coaxial duct when the jet Reynolds number, Rej, is large and the ratio of the jet radius to the duct radius, ε, is small. The analysis considers the distinguished double limit in which the Reynolds number Rea = Rejε for the final downstream flow is of order unity, when four ...

Axis thermal expansion switching in transition-metal zirconides TrZr2 by tuning the c/a ratio [PDF]
, 2023 This study examines the temperature-dependent evolution of the lattice constants for various CuAl2-type compounds, including NiZr2, (Co,Rh,Ir)Zr2, (Fe,Co,Rh,Ir)Zr2, and (Co,Ni,Cu,Rh,Ir)Zr2, in the pursuit of negative or zero thermal expansion.

FMR1 CGG expansions: Prevalence and sex ratios [PDF]
American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, 2013 AbstractWe have estimated the prevalence of FMR1 premutation and gray zone CGG repeat expansions in a population‐based sample of 19,996 male and female adults in Wisconsin and compared the observed sex ratios of the prevalence of FMR1 CGG premutation and gray zone expansions to theoretical sex ratios.

Effect of Edge Conditions on the Formability of Commercially Pure Titanium Sheet (Grade 2) at Room Temperature [PDF]
MATEC Web of Conferences, 2020 Titanium and its alloys are difficult to form, particularly at room temperature, due to their crystallographic structure and limited availability of slip systems.

Document expansion for image retrieval [PDF]
, 2010 Successful information retrieval requires effective matching between the user's search request and the contents of relevant documents. Often the request entered by a user may not use the same topic relevant terms as the authors' of the documents.

Confined swirling jets with large expansion ratios [PDF]
Journal of Fluid Mechanics, 2004 This paper presents the extension of our previous investigation of confined round jets with large Reynolds numbers and large expansion ratios (Revuelta, Sánchez & Liñán 2002a) to the case of swirling jets with swirl numbers of order unity. In the absence of vortex breakdown, we encounter the four-region asymptotic structure identified earlier for ...

The ratio of expansion to compression: A new measure of lifespan disparity
PLOS ONE, 2020 Numerous studies have shown that high life expectancy is closely related to low life disparity. Unlike life expectancy, which can be increased by mortality decline at any age, life disparity can either increase or decrease in response to mortality decline.
