Adaptive Control of Run‐and‐Tumble Escape in Pursuit‐Evasion Dynamics of Intelligent Active Particles

Advanced Intelligent Systems, EarlyView.
The pursuit‐evasion game is studied for two adversarial active agents, modeled as deterministic self‐steering pursuer and stochastic, cognitive evader. For a successful evasion strategy, the motile target has to exploit all available pursuer information, e.g., by tuning the tumbling frequency with the pursuer distance.

Prediction of Ballistic Limit for Composite Laminates Subjected to High-velocity Impact Using Static Perforation Test

Composites Research, 2013
The ballistic limit of Carbon/Epoxy composite laminates with the finite effective area are predicted by using the quasi-static perforation test and semi-empirical formula. The perforation energy were calculated from force-displacement curve in quasi-static perforation test.

The Progress of Orbitronics: The Enhancement of Orbital Torque Efficiency

Advanced Physics Research, EarlyView.
Orbit‐torque (OT) devices attract significant attention for their low‐power consumption and high stability in applications. This review systematically outlines strategies for enhancing OT efficiency. We categorize approaches into boosting orbital currents/torques and improving the orbital‐to‐spin conversion coefficient.

Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint

The Anatomical Record, EarlyView.
Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

Ballistic performances of the hourglass lattice sandwich structures under high-velocity fragments

Defence Technology
In this paper, the numerical simulation method is used to study the ballistic performances of hourglass lattice sandwich structures with the same mass under the vertical incidence of fragments. Attention is paid to elucidating the influences of rod cross-

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Effects of Hybrid Arrangement and Location of the Stronger Layer on the Impact Resistance of Composite Plate Target

Journal of Engineering and Sustainable Development, 2009
In this paper, response of hybrid woven fabric (E-Glass, Kevlar)/polyester composite laminates subjected to high velocity impact loading is discussed. E-Glass plain weaves with on layer of 3-end satin Kevlar were used to manufacture the laminate using ...

Maximizing Neurovascular Outcomes of Facial Transplantation: A Comprehensive Review

Clinical Anatomy, EarlyView.
ABSTRACT Facial transplantation is a division of reconstructive surgery which aims to improve the function and appearance of a face that has endured severe disfigurement. Currently, the face transplant procedure uses allogenic tissue, harvested from a brain‐dead donor, to replace damaged facial components.
