Beyond feasibility filters: How expertise heterogeneity enables innovation recognition

Strategic Management Journal, EarlyView.
Abstract Research Summary Organizations often struggle to identify promising innovations that balance novelty and feasibility in multidisciplinary domains, yet how does evaluator expertise heterogeneity shape these assessments? This study examines how evaluator expertise influences innovation evaluation through a field experiment with National ...

Mechanism of Temperature’s Acting on Electro-Hydraulic Servo Valve [PDF]

IEEE Access, 2019
To understand temperature's influence on the electro hydraulic servo valve, a theoretical model of describing the detailed mechanism is necessary. For a servo valve experiencing actual working conditions, the temperature variation acts on the performance of the torque motor, which results from drifts of the air gaps' thicknesses, the permanent magnets'
