Energy Science &Engineering, EarlyView.Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

Electromechanical shutter mechanism
, 1970 An electromechanical shutter mechanism capable of achieving shutter speeds up to 50 m/sec was designed, constructed and tested. An exploding wire was used to generate a cylindrically imploding blast wave. The input energy capability was 200 joules.

Triggered Calcium Lightning Programs Cochlear Development
Exploration, EarlyView.Summary: Before the onset of hearing, the developing inner ear generates spontaneous calcium signals that are thought to guide maturation. In this study, we discovered a rapid and widespread calcium flash—dubbed “Ca2+ lightning”—originating from supporting cells beneath the sensory hair cells, which triggers coordinated calcium waves across the entire ...

A Review of Probabilistic and Novel Approaches to Cost Assessment in CCUS Projects
Greenhouse Gases: Science and Technology, EarlyView.ABSTRACT Although the renewable energy sector is making progress, there is still a long way to go before green energy can be fully utilized. In this context, Carbon Capture Utilization and Storage (CCUS) technologies can act as a temporary bridge between a high‐emission past and a low‐emission future.

Global Strategy Journal, EarlyView.Abstract Research Summary This article develops a conceptual framework for understanding multinational enterprise (MNE) resilience in the era of cascading crises. We define resilience as the MNE's capacity to absorb disruption, maintain or restore functioning, and reconfigure operations as conditions shift.
