Analysis of a Pareto Mixture Distribution for Maritime Surveillance Radar

Journal of Electrical and Computer Engineering, 2012
The Pareto distribution has been shown to be an excellent model for X-band high-resolution maritime surveillance radar clutter returns. Given the success of mixture distributions in radar, it is thus of interest to consider the effect of Pareto mixture ...

Journey to Net‐Zero and Investment in Renewable Energy: Evidence From Developed and Developing Countries

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how geopolitical risk, high‐technology exports and the Paris Agreement shape investment in renewable energy across developed and developing economies. Drawing on structural contingency theory, we conceptualise renewable energy investment as a country‐level response to external contingencies and analyse a global panel of 100

Psychological stress during wartime and its association with seizure‐related emergency department utilization

Epilepsia, EarlyView.
Abstract Objective Psychological stress is commonly reported as a seizure precipitant in epilepsy, yet evidence from major crises remains limited and inconsistent. We examined whether the October 2023 Israel–Hamas conflict affected acute seizure‐related healthcare utilization among adults with epilepsy. Methods We conducted a retrospective cohort study

Status epilepticus: Updates on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Status epilepticus (SE) consists of prolonged, self‐sustaining seizures and is a common neurological emergency that causes respiratory compromise and neuronal injury. Without prompt treatment, the seizures can become resistant to benzodiazepines, leading to the progressive evolution of established, refractory, and super‐refractory SE.

Current Evidence on Best Practice Dental Survivorship Care for People With Head and Neck Cancer: An Overview of Systematic Reviews and Emerging Evidence

Head &Neck, EarlyView.
ABSTRACT Introduction Head and neck cancer (HNC) survival is improving, increasing the need to address long‐term survivorship issues. Dental survivorship—care before, during, and after treatment—remains inconsistent across services. We conducted a review of systematic reviews and emerging evidence to inform contemporary dental survivorship care for HNC

Peri‐implant disease pathogenesis animal models: Consensus report of Workgroup 1 of the IADR Implantology Research Group Best Evidence Consensus Symposium on Peri‐Implant Disease and Its Treatment

Journal of Periodontology, EarlyView.
Abstract Background The pathogenesis and etiology of peri‐implantitis demand a deeper understanding to lead to successful treatment modalities. Animal models of peri‐implantitis pathogenesis offer unique insights but their translational impact requires consideration of implant biomaterials science.
