PURPOSE The present investigation aimed to identify factors that predict reduced visual acuity in keratoconus from a prospective, longitudinal study. METHODS This report from the Collaborative Longitudinal Evaluation of Keratoconus (CLEK) Study used 7 years of follow-up data from 953 CLEK subjects who did not have penetrating keratoplasty in either eye at(More)
BACKGROUND Advancements in knowledge of obesity aetiology and mobile phone technology have created the opportunity to develop an electronic tool to predict an infant's risk of childhood obesity. The study aims were to develop and validate equations for the prediction of childhood obesity and integrate them into a mobile phone application (App). METHODS(More)
The 2014 Research Excellence Framework (REF2014) was conducted to assess the quality of research carried out at higher education institutions in the UK over a 6 year period. However, the process was criticized for being expensive and bureaucratic, and it was argued that similar information could be obtained more simply from various existing metrics. We were(More)
Theorem 4 (Recurrence): 9L w (x) = 2<3l_ n+l {x) + (x-l)$l_ n+2 (x). Corollary 1: (3l_ n (l) = 2 n-l {2u-2r-l}. Theorem 5 (Generating function): f>-,W = {u-r + [-u + x(u-l)]y}{l-(2y + (x-l)y 2)r l Analogously to the procedures in [2], we may derive a Binet form and a Simson formula for <3l_ " (x). The development outlined above complements that in [4] and(More)
Euler proved the following recurrence for p(n), the number of partitions of an integer n : (1) p(n) + ∞ X k=1 (−1) k (p(n − ω(k)) + p(n − ω(−k))) = 0 for ω(k) = 3k 2 +k 2. Using the Jacobi Triple Product identity we show analogues of Euler's recurrence formula for common restricted partition functions. Moreover following Kolberg, these recurrences allow us(More)
This study optimized the net present value (NPV) of profit of various switchgrass-based ethanol supply chains and estimated associated greenhouse gas (GHG) emissions in west Tennessee. Three configurations of feedstock harvesting and storage, including a large round baler system, a large square baler system, and a chopping/densification system, were(More)
