A 10-point interpolatory recursive subdivision algorithm for the generation of parametric surfaces [PDF]

open access: yes, 1991
In this paper, an interpolatory subdivision algorithm for surfaces over arbitrary triangulations is introduced and its properties over uniform triangulations studied.

Role of Prednisone and 25‐Hydroxyvitamin D on Bone Mineral Density and Osteoporosis in Systemic Lupus Erythematosus

open access: yesArthritis Care &Research, EarlyView.
Objective We evaluated the role of 25‐hydroxyvitamin D (25[OH]D), prednisone, and other risk factors for bone mineral density (BMD) loss and osteoporosis in systemic lupus erythematosus (SLE). Methods We calculated the association between 25(OH)D levels and other potential risk factors and BMD measures (spine T scores) and osteoporosis (defined as a T ...

Mycophenolate Mofetil Treatment Reduces the Risk of Treatment Escalation Due to Vascular Complications in Limited Cutaneous Systemic Sclerosis: Emulation of a Target Trial From the Italian Rheumatology Society SPRING Registry

open access: yesArthritis Care &Research, EarlyView.
Objective Mycophenolate mofetil (MMF) use in limited cutaneous systemic sclerosis (lcSSc) is relatively uncommon because of the lower fibrotic burden and the predominance of vascular complications. In vitro observations and clinical data from transplanted patients suggest a protective effect of MMF on endothelial function.

A Univariate Analysis of Risk Factors for Diabetic Nephropathy [PDF]

open access: yesBioautomation, 2006
This paper uses actual data from 267 patients with non-insulin-dependent (Type 2) diabetes mellitus in order to see how the various risk factors can affect the progression of diabetic nephropathy. Examination of each independent variable individually can

An Empirical Analysis of Equity Default Swaps (I): Univariate Insights [PDF]

open access: yes
The aim of this paper is to describe a new methodology to assess the risk of any Equity Default Swap (EDS). We show that as credit ratings can measure counter-party risk, it is technically possible to provide a quantitatively derived “through the cycle ...

Risk of Retinopathy Associated with Long‐Term Use of Hydroxychloroquine in Patients with Rheumatic Diseases: A Systematic Review and Meta‐Analysis

open access: yesArthritis Care &Research, EarlyView.
Objective We aimed to estimate the prevalence and cumulative incidence of hydroxychloroquine retinopathy (HCQ‐R) and its risk factors among patients receiving long‐term HCQ with rheumatic diseases through a systematic review and meta‐analysis of observational studies that used spectral‐domain optical coherence tomography (SD‐OCT) for screening ...

Univariate and Bivariate Empirical Mode Decomposition for Postural Stability Analysis

open access: yesEURASIP Journal on Advances in Signal Processing, 2008
The aim of this paper was to compare empirical mode decomposition (EMD) and two new extended methods of  EMD named complex empirical mode decomposition (complex-EMD) and bivariate empirical mode decomposition (bivariate-EMD).

Mixtures of Spatial Spline Regressions [PDF]

open access: yes, 2013
We present an extension of the functional data analysis framework for univariate functions to the analysis of surfaces: functions of two variables. The spatial spline regression (SSR) approach developed can be used to model surfaces that are sampled over
