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 ...

Class-$$\mathcal{K}$$ Function Bounds for Positive Definite Functions on Compact Sets
, 2019 This technical note focuses on positive definite functions defined on compact sets which contain the origin in their interior. It provides a class- function bounding inequality for the given positive definite function which is satisfied for its entire ...

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 ...

Homoclinic solutions for a class of second-order Hamiltonian systems with locally defined potentials
Electronic Journal of Differential Equations, 2017 In this article, we establish sufficient conditions for the existence of homoclinic solutions for a class of second-order Hamiltonian systems $$ \ddot u(t)-L(t)u(t)+\nabla W\bigl(t,u(t)\bigr)=f(t), $$ where L(t) is a positive definite symmetric ...

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 ...

Analysis of Saccular Function With Vestibular Evoked Myogenic Potential Test in Meniere's Disease
Acta Medica Iranica, 2017 Meniere’s disease is the disorder of inner ear characterized by vertigo, tinnitus and sensorineural hearing loss. The vestibular evoked myogenic potential (VEMP) test could be useful in the analysis of saccular function, and diagnosis of Meniere’s ...

Dunkl positive denite functions
, 2017 [[abstract]]We introduce the notion of Dunkl positive definite and strictly positive definite functions on R^d. This done by the use of the properties of Dunkl translation. We establish the analogue of Bochner's theorem in Dunkl setting.
