Positive definite functions on semi-homogeneous trees and spherical representations
, 2023 We consider the group $\mathrm{Aut}(T)$ of isometries of a semi-homogeneous tree $T=T_{q_+,q_-}$ with valencies $q_+ +1$ and $q_- +1$ and its two orbits $V_+$, $V_-$ respectively.

Seasonal Fluctuations of Plastochromanol‐8 and α‐Tocopherol Amounts in the Leaves of Cecropia Trees
Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT Plastochromanol‐8 (PC‐8) is a homologue of γ‐tocotrienol with a longer side chain (eight instead of three isoprene units) and therefore also a representative of the tocochromanol (vitamin E) group. PC‐8 has been determined in various plants and seeds, with Cecropia sp. leaves showing unusually high levels.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Strictly positive definite functions on spheres
, 1995 Neste trabalho, estudamos funções estritamente positivas definidas em esferas no espaço euclidiano m-dimensional. Tais funções podem ser usadas para resolver certos problemas de interpolação em esferas. Uma vez que as funções positivas definidas já foram

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs
The Anatomical Record, EarlyView.Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

Recent Developments in Approximation via Positive Definite Functions
, 1998 . Positive and conditionally positive definite functions, especially radial basis functions and similar functions for spheres, tori, and even Riemannian manifolds, are of interest because of the their well-known ability to synthesize a good surface fit ...

Per‐ and Polyfluoroalkyl Substances and Knee Osteoarthritis: Data From the Osteoarthritis Initiative
Arthritis &Rheumatology, EarlyView.Objective To examine whether concentrations of specific per‐ and polyfluoroalkyl substances (PFAS) and a mixture of PFAS relate to incident knee osteoarthritis (KOA) and knee pain progression. Methods Among a case‐cohort sample from the OA Initiative (n = 1,878), we examined associations of serum concentrations of eight PFAS with odds of developing ...

From Interferon Signature to the Clinical Landscape: Type I Interferonopathies
Arthritis &Rheumatology, EarlyView.Objective TypeI interferonopathies are heterogeneous diseases driven by dysregulated type I interferon (IFN‐I) signaling. Diagnosis is challenging due to clinical/molecular variability and the need for IFN‐I quantification. The aim of this study was to characterize the clinical, immunologic, genetic, molecular profiles of patients with suspected ...

Arthritis &Rheumatology, EarlyView.Objective The aim of this study was to investigate the prevalence and longitudinal evolution of anti–carbamylated fibrinogen antibodies (ACa‐Fib) of IgG and IgA isotypes in early rheumatoid arthritis (RA) and determine whether these antibodies provide additional diagnostic and prognostic information beyond anti–cyclic citrullinated peptide (anti‐CCP ...
