Complete biosynthesis of the clinical agent escin Ia

Abstract Escin Ia is a barrigenol-type triterpenoid specific to Aesculus seeds and is widely utilized in clinical practice for the treatment of cerebral edema, swelling, and venous insufficiency. Here, we fully elucidated its biosynthetic pathway by identifying ten previously unc...

Effect of Arctic Service Conditions on the Mechanical Properties and Damage Behavior of Glass Fiber and Carbon/Glass Hybrid-Reinforced Vinyl Ester Composites for Marine Applications

Glass fiber-reinforced polymer (GFRP) and carbon/glass hybrid fiber-reinforced polymer (HFRP) laminates with two vinyl ester resin systems were investigated to evaluate their early environmental response, residual mechanical performance, and damage behavior after moisture-assiste...

Numerical investigation of resistance reduction mechanisms and scale effects in tandem ship formation

Ship formation offers a strategic approach for resistance reduction in sustainable maritime transportation, whereas the underlying physical mechanisms and their scale dependencies remain insufficiently understood. In the present research, a URANS-based framework integrated with r...

Structural design and experimental validation of a titanium alloy hemispherical shell for ultra-deep-sea applications

This paper presents a comprehensive investigation into the design, numerical simulation, and experimental validation of an ultra-high-strength titanium alloy hemispherical shell intended for pressure-resistant applications at depth of 11,000 meters. Employing the strength and sta...

Vibration behavior and control study of an interlaced coupled beam system equipped with a nonlinear internal oscillator

Interlaced coupled-beam systems are widely used in engineering applications, including rigid mechanical arms, frame-type offshore platforms, shield machine support structures, and others. To demonstrate the potential of nonlinear oscillators for suppressing longitudinal, transver...
