A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

open access: yesJournal of Applied Polymer Science, EarlyView.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Tooth row allometry in domestic rabbits and nondomestic lagomorphs: Evidence for a decoupling of body and tooth row size changes in evolutionary time

open access: yesThe Anatomical Record, EarlyView.
Domestic rabbits of different body sizes differ disproportionately in the length of their tooth row or the length of their diastema. Abstract In various domestic mammals, smaller breeds tend to have proportionally larger teeth, whereas this is not a universal trend across mammals.

Nerve Growth Factor is Sufficient to Cause Multiple Osteoarthritis‐Relevant Pathologic Features in Naïve Murine Knee Joints

open access: yesArthritis &Rheumatology, EarlyView.
Objective Nerve growth factor (NGF), a key mediator of pain, is increased in osteoarthritic (OA) joints. Antibodies against NGF show analgesic effects in painful knee OA, but clinical development was stopped because of side effects in the joints. Knowledge about the biologic effects of NGF on joint tissues is limited. Therefore, we explored the effects

The Resolution of the Electron Point-Particle Paradox via the GTOC Domain Equivalence Postulate

open access: yes
In standard particle physics, the electron is classified as a zero-dimensional point particle due to the inability of modern colliders to measure a finite spatial radius below 10^-22 m. However, attributing a finite rest mass to a zero-volume coordinate results in a mathematical singularity of infinite density, violating the core principles of General ...

‘Where are the adults?’: Troubling child‐activism and children's political participation

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Children's political participation is a well‐established theme in childhood studies. In this article we offer an original account of child activism that takes into account the entangled and emergent aspect of children as activists. We begin with a historical and a conceptual review, noting the importance of mid‐20th century developments such ...
