Analysis of the longitudinal behavior of serum levels of Soluble Flt‐1 and Placental Growth Factor in pregnant women with Systemic Lupus Erythematosus

Arthritis Care &Research, Accepted Article.
Objective This study analyzed longitudinal trajectories of soluble fms‐like tyrosine kinase‐1 (sFlt‐1) and placental growth factor (PlGF) and sFlt‐1/PlGF ratio in a cohort of pregnant patients with systemic lupus erythematosus (SLE). Methods Blood samples were collected (14‐18, 24‐26, 30‐32, 34‐36 and 38‐40 weeks), stored at ‐80°C and evaluated for ...

Ageism in Rheumatology: the Healthcare Professional's Perspective

Arthritis Care &Research, Accepted Article.
Objective Ageism (age‐based stereotypes, prejudice, or discrimination) is prevalent and linked to prolonged disability and reduced lifespan in older adults. Little is known about ageism within rheumatology. This study explores the healthcare professional's (HCP) perception of the care of older adults and how ageist attitudes or perspectives may impact ...

Stability of initial-boundary value problem for quasilinear viscoelastic equations

Electronic Journal of Differential Equations, 2020
We investigate the stability of the initial-boundary value problem for the quasilinear viscoelastic equation $$\displaylines{ |u_t|^{\rho}u_{tt}-\Delta u_{tt}-\Delta u+\int_0^tg(t-s)\Delta u(s)ds=0, \quad \text{in }\Omega\times(0,+\infty),\cr u=0 ...

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

International Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

Characteristic Evolution and Matching

Living Reviews in Relativity, 2012
I review the development of numerical evolution codes for general relativity based upon the characteristic initial-value problem. Progress in characteristic evolution is traced from the early stage of 1D feasibility studies to 2D-axisymmetric codes that ...
