Carbon Neutrality and Business Models: Mixed‐Method Study of Business Strategies and Decarbonization Pathways

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study adopted a mixed‐method approach to examine decarbonization business models/strategies employed across the energy ecosystem. In study 1, we conducted a systematic literature review of 94 studies to identify business models/strategies mapped to five energy ecosystem contexts—energy systems' transition, energy systems—demand side ...

Renewable Energy Source Integration With Intelligent Neuro‐Fuzzy Control for Microgrid System

open access: yesBattery Energy, EarlyView.
A Landsman converter with high amplification is employed to optimize voltage generated by solar panels due to their relatively low output. An unstable and often fluctuating converter output is stabilized by the ANFIS controller. The error signal is acquired through reference voltage comparison analysis V DC ref ${{V}}_{{{DC}}_{{ref}}}$ to the actual DC

Management of Lost Atherectomy Devices in the Coronary Arteries

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Rotational and orbital atherectomy are important tools to treat calcific coronary disease. Entrapment of an atherectomy device, that is, rotational atherectomy burr or orbital atherectomy crown, is a serious complication during atherectomy. Loss of an atherectomy device is a more challenging complication that usually follows device entrapment.
