Modeling Fiber Dispersion in a Single‐Screw Extruder for Long Fiber‐Reinforced Thermoplastics

open access: yesPolymer Composites, EarlyView.
Fiber dispersion throughout the screw channel ABSTRACT Understanding the mechanics of fiber attrition during the plasticizing process is important in predicting the strength of long fiber‐reinforced thermoplastics (LFT) composites. Fiber dispersion has been found to impact fiber damage during processing and therefore final fiber length in the final ...

Arbuscular mycorrhiza in the urban jungle: Glomeromycotina communities of the dominant city tree across Amsterdam

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Trees in cities provide a great number of benefits to people and nature, but they are challenged by harsh conditions. Trees rely on helpful fungi in their roots to get essential nutrients from the soil, but we do not know which of these fungi are resistant to city landscapes.

Right tree, right place, right reason: Using knowledge exchange and research co‐design to explore current challenges and opportunities for sustainable urban forest management

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The urban forest provides important environmental and health and well‐being benefits to people living in cities. However, sustainable management of urban trees is challenging as they face interrelated pressures from the urban environment, pests and diseases and climate change.

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Elemental bioaccumulation as trophic discriminator in Southeast Alaska gray wolves: Marine-terrestrial diet shifts

open access: yesJournal of Trace Elements and Minerals
Gray wolves (Canis lupus) in Southeast Alaska exhibit diverse foraging strategies shaped by regional ecological factors. Stable isotope (δ13C and δ15N) and trace element (TE) analyses were used to evaluate dietary patterns and contaminant exposure in ...

A Novel Crawling Robot Based on the Hexagonal Mesh Structure and Enhanced PID Control Strategy

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The locomotion of crawling robots is similar to that of caterpillars, relying on foot adhesion and body contraction to ensure flexible movement without compromising stability. However, most existing pneumatic soft crawling robots are incapable of simultaneously achieving forward, backward, turning, and climbing capabilities.

Genetic Connectivity in a Cooperatively Breeding Carnivore Between Two Protected Areas

open access: yesEcology and Evolution
Wildlife populations are increasingly threatened by human activities. Most studies, however, are often short in duration or do not encompass the large spatial extent necessary to measure the potential effects of human activities on population vital rates.
