Early Diagnosis of Axial Spondyloarthritis Is Associated With Less Long‐Term Spinal Structural Damage: A Longitudinal Analysis of the Swiss Clinical Quality Management in Rheumatic Diseases Registry

Arthritis &Rheumatology, EarlyView.
Objective The Assessment of SpondyloArthritis international Society recently defined early axial spondyloarthritis (axSpA) as a duration of two years or less of axial symptoms. Previous studies have shown no significant difference in short‐term outcomes between patients with early and established axSpA treated with biologic/targeted synthetic disease ...

Subspace‐Based System Identification From Binary Measurements

Asian Journal of Control, EarlyView.
ABSTRACT This paper is concerned with subspace identification from binary measurements for systems whose dynamical behavior can be splited into a deterministic and a stochastic subsystem. An identification algorithm is detailed. The main contribution of the proposed identification algorithm lies in the identification of both the deterministic subsystem

Biogas production from Opuntia stricta Haw.: microbial diversity and solid load influence on sludge recycle systems

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The search for alternative and sustainable energy sources becomes urgent as energy demand increases and fossil fuels become less available, especially in water‐scarce regions such as the Brazilian semi‐arid region, where current projections of global warming and the expansion of arid and semi‐arid zones point to a future of desertification ...

Asymptotic normality of spectral estimates

The asymptotic normality of some spectral estimates, including a functional central limit theorem for an estimate of the spectral distribution function, is proved for fourth-order stationary processes.

pyFDRT: An open‐source Python tool for Fourier‐transform analysis of the distribution of relaxation times in electrochemical impedance spectra

Bulletin of the Korean Chemical Society, EarlyView.
pyFDRT is an open‐source tool that converts an impedance spectrum into a quantitative equivalent circuit. Its Fourier‐transform stage requires no discretization basis or regularization parameter, and the non‐negative refinement selects its own parameters, and an information criterion determines the relaxation process count.

Innovation Pathways to Carbon Efficiency: Disentangling the Effects of AI, R&D, and Clean Energy Blessings on U.S. Environmental Sustainability

Business Strategy and the Environment, EarlyView.
ABSTRACT The United States (U.S.) faces challenges in achieving its ambitious net‐zero carbon emissions target by 2050, with current emissions having fallen by less than 1% in 2024. Despite an investment of $500 billion in low‐carbon resources while holding the second‐largest green technology patent portfolio globally, it is further imperative to ...
