Long‐Term Institutional Ownership and Corporate Breakthrough Innovation: Evidence From the Perspective of Patient Capital

Managerial and Decision Economics, EarlyView.
ABSTRACT This paper examines whether institutional ownership with different investment horizons is related to corporate breakthrough innovation, using panel data of Chinese A‐share listed firms from 2014 to 2023. Long‐term institutional ownership is positively and significantly associated with breakthrough innovation, while short‐term institutional ...

Designing γ‐TiAl Alloys With Refined Twin‐Lamellar Microstructures via Machine Learning‐Driven Phase‐Field Methods

Materials Genome Engineering Advances, EarlyView.
Dual‐phase γ‐TiAl alloys with refined twin‐lamellar (RTL) structures exhibit optimal strength‐ductility synergy. Here, phase‐field simulations reveal composition‐stress‐dependent refined twin‐lamellar (RTL) microstructure evolution. Machine learning (CatBoost + NSGA‐III) trained on phase‐field images predicts optimal RTL‐stress‐composition design space.
