Enhanced disturbance mitigation in nonlinear time delay systems with applications to double boost converters in microgrid environments.

This study proposes an enhanced Smith Predictor (ESP) based Modified repetitive control (MRC) technique to develop a precise tracking performance of the input delayed double boost converter model, which is highly influenced by disturbances and saturation nonlinearity. A group of inequalities is derived on the basis of Lyapunov stability concept, which are in the form of linear-matrix-inequalities (LMIs) to guarantee the asymptotic stability and tracking performance of the considered delayed double boost converter. To be more specific, the proposed Lyapunov method not only provides the asymptotic stability of the system but also design the controller parameters when the feasibility of the derived LMIs are analyzed.

Evaluation of Risk Factors for Dupilumab-Associated Ocular Sequelae in the Treatment of Atopic Dermatitis.

Dupilumab is a monoclonal antibody that inhibits interleukin-4 (IL-4) and interleukin-13 (IL-13) signaling and is used in the treatment of moderate-to-severe atopic dermatitis (AD) in those six months or older who are uncontrolled on or cannot tolerate topical treatments. Ocular surface disease is a recognized adverse effect of dupilumab, yet few studies describe the risk factors for developing ocular adverse effects. There are no standardized recommendations for monitoring patients on this medication.

Perianal angiolymphoid hyperplasia with eosinophilia mimicking Kaposi sarcoma in a patient living with HIV.

A woman in her 70s with well-controlled HIV on antiretroviral therapy presented with a several-month history of an asymptomatic perianal lesion. Skin examination showed a 0.5-1 cm red-pink, shiny, exophytic papule with visible telangiectasias near the anal verge.

Factors influencing evidence-based cardiovascular disease prevention programming in rural African American communities: a community-engaged concept mapping study.

Background: African Americans experience cardiovascular disease (CVD) disparities, and the burden is greatest in the rural south. Although evidence-based CVD prevention and management programs have been tailored to this context, implementation has been limited and not sustained long-term. To understand how to implement and sustain evidence-based CVD programs at scale, we must explore the perspectives of organizations serving rural African American communities and situate findings within foundational Implementation Science frameworks.

Repeat Procedures After Pulsed Field Ablation for Atrial Fibrillation: MANIFEST-REDO Study.

Background: Initial clinical studies of pulsed field ablation (PFA) to treat atrial fibrillation (AF) indicated a >90% durability rate of pulmonary vein isolation (PVI). However, these studies were largely conducted in single centers and involved a limited number of operators. The electrophysiological findings and outcomes in patients undergoing repeat ablation after an initial PF ablation for AF are incompletely understood.
