Mapping Bicycle Crash Risk Patterns on the Local Scale

Safety, 2016
Currently, mainly aggregated statistics are used for bicycle crash risk calculations. Thus, the understanding of spatial patterns at local scale levels remains vague.

Bicycling to university: evaluation of a bicycle-sharing program in Spain [PDF]

Health Promotion International, 2013
This study examined the change in behavioral stages (e.g. contemplation, action and maintenance) of cycling to university before and after the implementation of a new public bicycle share program (PBSP) and promotion of its use. The study also determined the change in the prevalence, correlates of PBSP use and potential role in the promotion of healthy

Molecular Rotors: From Newtonian Fluids to Functional Materials as Viscosity and Temperature Sensing Tools

Advanced Functional Materials, EarlyView.
Molecular rotors are fluorescent molecules that are sensitive to viscosity and temperature variations in the environment. They exhibit a direct correlation between fluorescence and viscosity within Newtonian fluids. However, this correlation becomes less straightforward in complex systems.

Discovery and chemical optimisation of a potent, Bi-cyclic antimicrobial inhibitor of Escherichia coli PBP3

Communications Biology
Penicillin binding proteins (PBPs) are well validated antimicrobial targets, but the prevalence of β-lactamase driven resistance and, more rarely, target-based mutations, necessitates new classes of PBP-targeting drugs. Here we describe the discovery and

Parental attitudes and family helmet use for all-terrain vehicles and bicycles

Injury Epidemiology, 2020
Background Helmets prevent head trauma in both all-terrain vehicle (ATV) and bicycle crashes. This pilot study’s objective was to compare family helmet use and participant attitudes regarding helmets for ATVs versus bicycles.

Boolean Logic‐Based Control Over Recombinant Protein Biomaterial Degradability and Therapeutic Delivery

Advanced Materials, EarlyView.
Fully recombinant protein‐based biomaterials execute complex Boolean logic for user‐programmable material degradation and concomitant therapeutic cargo release. Biologics, such as growth factors, can be incorporated within the crosslinkers as “drugamers”, while encapsulated cells can be released according to nested YES/OR/AND‐type logical operations ...

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

Will e-bikes revolutionize urban mobility? Development and application of a transport model differentiating between conventional and electric bicycle traffic

European Transport Studies
Increasing cycling is crucial for building sustainable cities. Electric bicycles reduce the physical effort required for cycling, particularly in hilly areas and for individuals with limited strength, contributing to lower car use and promoting social ...

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...
