A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

Energy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...

Triboelectric nanogenerators for vehicle intelligent cockpits

FlexMat, EarlyView.
Converting mechanical stimuli from drivers and vehicle motion into electrical signals, triboelectric nanogenerators provide promising interfaces toward passive, flexible, distributed and intelligent sensing for next‐generation automotive cockpits to support three core functional dimensions: driver state monitoring, vehicle state monitoring, and human ...

Engineering an artificial trachea: Quantitative benchmarks and modular strategies for mechanics, epithelialization, and vascular integration

FlexMat, EarlyView.
In this work, we first examine the limitations of surgical repair and stenting, including migration, granulation, mucus plugging, and infection. We then translate these failures into engineering constraints involving geometry, mechanics, fixation, degradation, junctional stress, and remodeling.

Temporal Robustness in Cross‐Country Gross Domestic Product Forecasting: Evidence From Classical, Regime‐Switching, and Ensemble Models

Journal of Forecasting, EarlyView.
ABSTRACT This study evaluates whether the relative performance of gross domestic product forecasting models is temporally robust across economies and changing macroeconomic conditions. Using annual real gross domestic product data from the World Bank for 177 separately reported economies and territories, we conduct a common‐vintage pseudo‐out‐of‐sample

Coupled Assessment of Injection Pressure–Driven Risk, Trapping Evolution, and Cost Uncertainty in Geological CO2 Storage

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Scaling geological CO2 storage requires simultaneously controlling plume migration, pressure buildup, geomechanical integrity, and monitoring cost under deep subsurface uncertainty. Yet early‐stage assessments often treat these elements in isolation, obscuring the decision‐critical couplings between pressure‐defined regulatory exposure and ...

Political Transition, Health System Reform and Trust in Childhood Vaccination in Ukraine: A Qualitative Case Study

The International Journal of Health Planning and Management, EarlyView.
ABSTRACT Trust in childhood vaccination is a concern for health policy, particularly in settings of political transition and conflict, where governance, institutional legitimacy and service delivery are often under strain. It is against this backdrop that this study aims to describe evolving interactions between health system governance, trust and ...

CEO's Influence on Top Management Team's Employee Engagement: A Qualitative Study

Human Resource Development Quarterly, EarlyView.
ABSTRACT This study explores how chief executives officers (CEOs) influence top management team (TMT) members' employee engagement. Using a constructivist phenomenological approach, the research examines ways CEOs shape TMT's employee engagement. Fifteen TMT professionals participated in semi‐structured interviews, and the data were analyzed through a ...

Formative and Reflective Measurement Models in Workplace Learning Research: A Critical Review and Guidelines

Human Resource Development Quarterly, EarlyView.
ABSTRACT Quantitative empirical research in workplace learning regularly makes use of measurement instruments that operationalize theoretical constructs. However, in domains related to workplace learning, high levels of measurement model misspecifications—up to 62% of all cases—have been identified.
