Manifold limits on seed production by individual flowering plants

American Journal of Botany, EarlyView.
Abstract Premise Historically, angiosperm seed production has been considered to be either pollen or resource limited. However, seed production involves more than pollen and seed resources and typically involves multiple ovules in multiple flowers. Therefore, various constraints may act simultaneously. Methods Proportional components of seed production

Hierarchical Spline Approximation

, 2001
We discuss spline refinement methods that approximate multi-valued data defined over one, two, and three dimensions. The input to our method is a coarse decomposition of the compact domain of the function to be approximated consisting of intervals (univariate case), triangles (bivariate case), and tetrahedra (trivariate case).

Long‐Term Quality of Life in 1777 Persons With Hodgkin Lymphoma and 6166 Matched Comparators

American Journal of Hematology, EarlyView.
ABSTRACT Survival has improved substantially for patients with Hodgkin lymphoma (HL), but long‐term quality of life (QoL) remains incompletely understood. This was a Danish, nationwide, cross‐sectional study of QoL among persons with a diagnosis of HL matched 1:10 to general population comparators.

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

International 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.

Distinct Prescription Patterns Emerge Years Before ALS Diagnosis: A Nationwide Registry‐Based Study

Annals of Neurology, EarlyView.
Objective The prodromal phase of amyotrophic lateral sclerosis (ALS) is poorly defined. We aimed to characterize prescription drug use patterns in the pre‐diagnostic period by analyzing nationwide prescription data to identify the earliest divergence between individuals who developed ALS and matched healthy controls.

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

Annals 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

Gamma Splines and Wavelets

Journal of Engineering, 2013
In this work we introduce a new family of splines termed as gamma splines for continuous signal approximation and multiresolution analysis. The gamma splines are born by -times convolution of the exponential by itself.
