Decentralised gambling applications are a new way for individuals to engage in online gambling. Decentralised gambling applications are distinguished from traditional online casinos in that individuals use cryptocurrency as a stake. Furthermore, rather than being stored on a traditional server, decentralised gambling applications are stored on a cryptocurrency’s blockchain.Previous work in the player behaviour tracking literature has examined the spending profiles of gamblers on traditional online casinos. However, parallel work has not taken place in the decentralised gambling domain. The profile of gamblers on decentralised gambling applications are therefore not known.This paper explores 2,232,741 transactions from 24,234 unique addresses to three such applications operating atop the Ethereum cryptocurrency network over 583 days. We present spending profiles across these applications, providing the first detailed summary of spending behaviours in this technologically advanced domain. We find that the typical user spends approximately \$110 equivalent across a median of 6 bets in a single day, although heavily involved bettors spend approximately \$100,000 equivalent over a median of 644 bets across 35 days. Our findings suggest that the use of decentralised gambling applications typically involves lower and less frequent expenditures than other online casinos, but that the most heavily involved players in this new domain spend substantially more. Our findings also demonstrate the use of these applications as a research platform, specifically for large scale longitudinal in-vivo data analysis.

Finger Length Ratio

Relative finger lengths, especially the second-to-fourth finger length ratio, have been proposed as useful markers for prenatal testosterone action. This claim partly depends on an association of relative finger lengths in adults with related sex differences in children and infants. This paper reports the results of a study using serial radiographs to test for both sex differences in the fingers of infants and children and for a relationship between sex differences in the children and infant finger and adult finger length ratios. This is the first study using long-term serial data to evaluate the validity of finger length ratios as markers. We found not only that sex differences in finger length ratios arise prior to puberty, but that sex differences in the fingers of children are highly correlated with adult finger length ratios. Our results strongly encourage the further use of finger length ratios as markers of perinatal testosterone action.

For an abdominal aortic aneurysm (AAA) in vivo there are multiple tissues contacting its boundary, none of which have been fully considered for their effect throughout disease progression. Trends such as arterial asymmetry, surface curvature flattening, and arterial tortuosity could be significantly influenced by both surrounding tissue and hemodynamic factors. In order to quantify either the combined or separate influence of such factors during disease progression a precise characterization of aneurysm geometry evolution is needed. Multiple methods for geometrical parameterization of abdominal aortic aneurysms (AAAs) have been previously developed using isolated patient CT scan data but the focus has been mainly on the association of such geometrical parameters with the rupture risk and the efficacy of the parameterization is not fully investigated for a longitudinal study yet (multiple CT scans per patient at progressive intervals) [1]. For this study we have produced a series of 3D models for AAAs in longitudinal studies, developed an arterial centerline generation algorithm, and automated a geometric parameterization procedure for the arterial surfaces. It should be noted that the caliber of our collection of data is relatively rare as it is high resolution, features many patients, and on average has 4–5 images per patient.
