Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe 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

open access: yesThe 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 ...

Per‐ and Polyfluoroalkyl Substances and Knee Osteoarthritis: Data From the Osteoarthritis Initiative

open access: yesArthritis &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 ...

Conditionally Positive Definite Kernels and Pontryagin Spaces

open access: yes, 2008
. Conditionally positive definite kernels provide a powerful tool for scattered data approximation. Many nice properties of such methods follow from an underlying reproducing kernel structure.

From Interferon Signature to the Clinical Landscape: Type I Interferonopathies

open access: yesArthritis &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 ...

Anti–Carbamylated Fibrinogen Autoantibodies of IgG and IgA Isotypes Contribute to a Better Prognostic Stratification in Very Early Rheumatoid Arthritis: Data From the French National ESPOIR Cohort

open access: yesArthritis &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 ...

Outcomes in progressive pulmonary fibrosis in systemic autoimmune rheumatic diseases: real‐world data from the ILD‐PRO Registry

open access: yesArthritis &Rheumatology, Accepted Article.
Objective We evaluated baseline characteristics, treatment patterns, and outcomes in patients with systemic autoimmune rheumatic disease‐associated progressive pulmonary fibrosis (SARD‐PPF) and evaluated whether outcomes differed by SARD subtype. Methods The ILD‐PRO Registry is a prospective multicenter US registry of patients with PPF.

Performance improvement of discrete‐time linear‐quadratic regulators applied to uncertain linear systems using the Tikhonov regularization method

open access: yesAsian Journal of Control, EarlyView.
Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

Controllability and Observability Conditions for Impulsive DAEs on Time Scales

open access: yesAsian Journal of Control, EarlyView.
ABSTRACT This paper establishes criteria for controllability and observability in a class of linear time‐invariant impulsive differential‐algebraic equations (DAEs) defined on a time scale. Controllability is defined as the ability to transfer the system state from any initial condition to any desired state within a finite time interval using an ...

Synchronization‐Performance‐Oriented Frequency‐Domain Iterative Learning Control for Wafer and Reticle Stages

open access: yesAsian Journal of Control, EarlyView.
ABSTRACT The synchronization accuracy between the wafer stage and reticle stage in lithography is critical to overlay and critical dimension uniformity. Existing iterative learning control (ILC) methods indirectly optimize synchronization via time‐domain errors, failing to balance low‐frequency tracking accuracy and high‐frequency noise suppression ...
