Extending fundamental formulas from classical B-splines to quantum B-splines

open access: yes, 2015
We derive a collection of fundamental formulas for quantum B-splines analogous to known fundamental formulas for classical B-splines. Starting from known recursive formulas for evaluation and quantum differentiation along with quantum analogues of the ...

Multiquadric B-splines [PDF]

open access: yes, 1994
Our purpose in this paper is to show that the analogy between polynomial splines and generalized multiquadrics is very strong. In particular combinations of multiquadrics, called ℣-splines, will be defined that are analogues of polynomial B-splines ...

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Segmented Regression Based on B-Splines with Solved Examples [PDF]

open access: yesStatistika: Statistics and Economy Journal, 2015
The subject of the paper is segmented linear, quadratic, and cubic regression based on B-spline basis functions. In this article we expose the formulas for the computation of B-splines of order one, two, and three that is needed to construct linear ...

Numerical simulation of Burgers’ equation using cubic B-splines

open access: yesNonlinear Engineering, 2017
In this paper, a numerical θ scheme is proposed for solving nonlinear Burgers’ equation. By employing Hopf-Cole transformation, the nonlinear Burgers’ equation is linearized to the linear Heat equation.

Dosing Interval Extension of Dupilumab in CRSwNP: Five‐Year Real World Outcomes

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is a persistent, often Type 2‐mediated inflammatory disease that markedly impairs quality of life. While dupilumab provides rapid improvement, there is limited evidence on long‐term outcomes beyond 2 years, and the clinical impact of dosing‐interval extension remains unclear.

Alzheimer's Disease Co‐Pathology and Cognitive Impairment in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Neurology, EarlyView.
Objectives Amyotrophic lateral sclerosis (ALS) and Alzheimer's disease (AD) share neuropathological features, including tau, amyloid, and TDP‐43 pathology. This study investigated whether AD‐related pathological changes are associated with cognitive impairment ALS. Methods Cerebrospinal fluid (CSF total‐tau, phosphorylated‐tau, beta‐amyloid) and plasma
