Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

open access: yesAdvanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

Examining shock wave flow past the brim of a helmet using schlieren imaging

open access: yesHeliyon
Increasing the protection a helmet provides the user from shock waves can help reduce the prevalence of blast induced traumatic brain injury (bTBI). Previous research has shown that air enters and gets trapped in the helmet-head cavity and can increase ...

Investigating helmet promotion for cyclists: results from a randomised study with observation of behaviour, using a semi-automatic video system.

open access: yesPLoS ONE, 2012
IntroductionHalf of fatal injuries among bicyclists are head injuries. While helmet use is likely to provide protection, their use often remains rare.

A Critical Time Window of Neocortex Modulation for Remote Fear Memory in Rats and Humans

open access: yesAdvanced Science, EarlyView.
This study identifies a delayed consolidation window around 18 h after fear learning in the mPFC essential for remote fear memory. VTA dopaminergic input during this window sustains remote memory in rats, while non‐invasive stimulation of homologous human mPFC at the corresponding time selectively weakens remote but not recent fear memory, revealing a ...

Comparison of Neck Pain and Disability With and Without Helmet in Commercial Bikers

open access: yesLink Medical Journal of Health and Community Research
Background: Neck pain is a common musculoskeletal complaint among commercial bike riders because of prolonged riding duration, sustained cervical posture, repetitive road vibration, occupational workload, and possible helmet-related biomechanical ...

Tumor Exposomics: A New Paradigm for Individualized Continuous Exposure Monitoring

open access: yesAdvanced Science, EarlyView.
Tumor exposomics integrates continuous monitoring of environmental exposures, endogenous biological responses, and behavioral factors within a unified temporal framework. By combining multimodal sensing technologies with AI‐enabled causal modeling, this emerging paradigm reconstructs exposure‐damage trajectories and supports individualized dynamic risk

Explaining the Origin of Negative Poisson's Ratio in Amorphous Networks With Machine Learning

open access: yesAdvanced Intelligent Discovery, EarlyView.
This review summarizes how machine learning (ML) breaks the “vicious cycle” in designing auxetic amorphous networks. By transitioning from traditional “black‐box” optimization to an interpretable “AI‐Physics” closed‐loop paradigm, ML is shown to not only discover highly optimized structures—such as all‐convex polygon networks—but also unveil hidden ...

A Comprehensive Review on Additive Manufacturing of Smart Components: Technologies, Applications, and Future Scope

open access: yesAdvanced Intelligent Systems, EarlyView.
How can additive manufacturing enable components that sense, adapt, heal, and power themselves? This review synthesizes recent advances in smart functionalities, manufacturing technologies, and intelligent design strategies, revealing a pathway toward fully integrated, autonomous, and multifunctional systems across diverse engineering sectors. Additive

Severe Headbanging Responsive to Levodopa in a Child With FOXP1 Syndrome

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT We report a 9‐year‐old female with FOXP1 syndrome due to a de novo in‐frame deletion in the FOXP1 gene. The child has a severe neurodevelopmental disorder including global developmental delay and autism spectrum disorder. At age 2, she developed severe headbanging, which was progressive and did not respond to multidisciplinary, behavioral ...

Standards for helmets [PDF]

open access: yesCanadian Medical Association Journal, 2012
I want to thank CMAJ for publicizing that most domestic and imported snow sport helmets currently do not meet the Canadian Safety Association’s (CSA) standards for preventing concussion and withstanding multiple impacts.1 On Mar. 19, 2007, I tabled Private Member’s Bill C-412 that would prohibit the advertising, import or sale of recreational snow ...
