Approximation error estimates and inverse inequalities for B-splines of maximum smoothness
, 2015 In this paper, we develop approximation error estimates as well as corresponding inverse inequalities for B-splines of maximum smoothness, where both the function to be approximated and the approximation error are measured in standard Sobolev norms and ...

Cardinal Hermite Spline Interpolation with Shifted Nodes [PDF]
Mathematics of Computation, 1994 The class \(S_{m,2} (\mathbb{Z})\) of \(L_ 1 (\mathbb{R})\)-bounded cardinal splines of degree \(m\) with knots at the integer points \(j \in \mathbb{Z}\) and defect 2 is studied. Given \(0 < \tau_ 1 \leq \tau_ 2 \leq 1\) and data sequences \(\{y_ i^{(0)}\}\), \(\{y_ i^{(1)}\}\) \((j = - \infty : + \infty)\) from \(L_ 1\), the interpolation problem ...

Arthritis Care &Research, EarlyView.Objective Recent inflammatory bowel disease (IBD) treatment guidelines have recommended against nonsteroidal anti‐inflammatory drug (NSAID) use despite prevalent musculoskeletal symptoms and opioid overuse in this population. Given the discordance between changing national guidelines and potential clinical utility, we sought to assess national temporal

Isogeometric Transfinite Elements: A Unified B-Spline Framework for Arbitrary Node Layouts
AxiomsThis paper presents a unified framework for constructing partially unstructured B-spline transfinite finite elements with arbitrary nodal distributions. Three novel, distinct classes of elements are investigated and compared with older single Coons-patch

Elliptic scaling functions as compactly supported multivariate analogs of the B-splines [PDF]
, 2013 In the paper, we present a family of multivariate compactly supported scaling functions, which we call as elliptic scaling functions. The elliptic scaling functions are the convolution of elliptic splines, which correspond to homogeneous elliptic ...

Exponential Splines of Complex Order
, 2013 We extend the concept of exponential B-spline to complex orders. This extension contains as special cases the class of exponential splines and also the class of polynomial B-splines of complex order.

Arthritis Care &Research, EarlyView.Objective We assessed the effectiveness of PrismRA to improve clinical outcomes among patients with rheumatoid arthritis (RA) initiating treatment with a biologic or targeted synthetic disease‐modifying antirheumatic drug (b/tsDMARD). Methods PrismRA incorporated 19 gene expression features and four clinical features to assess a patient's likelihood of

3D‐Printed Serial Snap‐Through Architectures for Programmable Mechanical Response
Advanced Engineering Materials, EarlyView.A serial snap‐through architecture is realized using compact 3D‐printed von Mises truss units arranged in a staged cascade. Their geometry and boundary conditions program multistage mechanical responses with plateaux and re‐hardening regimes. An inverted‐compliance model predicts these behaviors and enables analytical design of programmable force ...

Real-time path planning optimisation algorithm for obstacle avoidance [PDF]
, 2006 This paper presents a new real-time path planning algorithm suitable for implementation on small mobile robots to aid navigation in unknown environments. The Random Obstacle Avoidance (R.O.A) algorithm was developed for small robots and it can be used as

Spectrophotometric calibration of low-resolution spectra
, 2020 Low-resolution spectroscopy is a frequently used technique. Aperture prism spectroscopy in particular is an important tool for large-scale survey observations. The ongoing ESA space mission Gaia is the currently most relevant example.
