Unveiling the Microvasculature: The Index of Microcirculatory Resistance and Its Expanding Role in Cardiovascular Care

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Index of microcirculatory resistance (IMR) is a cutting‐edge, wire‐based tool that advances the capability assessment of coronary microvascular function. By utilizing distal coronary pressure and mean transit time under maximal hyperemia, IMR delivers consistent, reproducible insights into the microvasculature's dynamic health.

A Novel Marker Triglyceride Glucose Index in Predicting the Development of No-reflow in Acute Coronary Syndrome without ST-segment Elevation

Haseki Tıp Bülteni
Aim:The triglyceride-glucose (TyG) index is a new marker that predicts adverse clinical outcomes in coronary artery disease. We aimed to investigate the relationship between the TyG index and the no-reflow phenomenon after percutaneous coronary ...

Influence of Temperature on the Reliability of Graphene‐Based Ozone Sensors

Small, EarlyView.
The reliability and stability of inkjet‐printed graphene flake sensors are evaluated. Stress assessments take place in ozone‐rich environments and at elevated temperatures, with the observation of a change in resistance. Surface‐sensitive techniques serve to investigate the failure and degradation mechanisms of printed graphene.

Anode‐Free All‐Solid‐State Batteries: Understanding Limitations and Charting a Path to Enhanced Performance

Small, EarlyView.
This review examines four factors that drive interfacial instability in sulfide‐based anode‐free all‐solid‐state batteries and thoroughly reviews corresponding performance‐enhancing strategies. The strategies are organized as follows: (1) interlayer engineering, (2) pressure‐regulating buffer layers, (3) other methods, including sacrificial cathodes ...

Developing an evidence‐based model to implement co‐governance

Australian Journal of Public Administration, EarlyView.
Abstract Governments are seeking innovative ways to address complex policy issues in increasingly fragmented and fiscally constrained service contexts. Co‐governance is a relatively new mechanism for facilitating collective decision‐making between government and other stakeholders. Effective co‐governance can be difficult to establish and resource‐ and
