Fish Scales: A Multifunctional Biomaterial from Nature
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Feedback control for yaw angle with input nonlinearity via input-state linearization
, 2006 This paper discusses the yaw control of small-size unmanned helicopter. The yaw dynamics of helicopter involve input nonlinearity, time-varying parameters and the couplings between main and tail rotor.

Eye &ENT Research, EarlyView.ABSTRACT Background Contact lenses (CLs) are increasingly used worldwide for refractive error correction because of their optical, cosmetic, and functional advantages over spectacles. However, although their safe and effective use depends on adequate knowledge and proper hygiene practices, there is limited evidence on contact lens‐related knowledge ...

Energy Science &Engineering, EarlyView.Passing vehicles generate short‐duration wakes that can be redirected toward a vertical‐axis turbine. The interaction between wake structure, blade count, and rotational speed governs transient torque production. Low‐solidity configurations combined with tuned rotational speed enhance energy extraction under vehicle‐induced gusts.

Yaw control of helicopter: an adaptive guaranteed cost control approach
, 2009 This paper discusses the adaptive robust guaranteed cost tracking control problem of linear systems with time-varying uncertainties. The bounds of varying uncertainty ellipsoidal are obtained by set membership identification method. The proposed adaptive

A Comprehensive Review of AI‐Powered Energy Systems
Energy Science &Engineering, EarlyView.The role of Artificial Intelligence (AI) in developing next‐generation energy systems is getting more day by day. Therefore, incorporating AI enables real‐time decision‐making and advanced grid management, which are essential for optimizing the use of intermittent renewable sources like wind and solar power.

Similar locomotor patterns across Quarter Horse disciplines inform lameness assessment
Equine Veterinary Journal, EarlyView.Abstract Background Lineage‐based selection is central to the Quarter Horse industry and is often justified by the assumption that morphology determines locomotor function. However, objective evidence linking static conformation to discipline‐specific locomotor behaviour under standardised conditions remains limited.
