String Figuring young children's perspectives of quality in English early childhood education and care

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.

Animal empathy reconsidered: a multidimensional profile account

open access: yesBiological Reviews, EarlyView.
ABSTRACT Empathy is the glue that holds societies together and yet several fundamental questions about empathy persist. What is empathy (the definitional question)? Is it uniquely human and, if not, which nonhuman animals possess empathy (the distribution question)? Which type or quality of empathy is realized in different species (the quality question)

Shock vibration test of concrete [PDF]

open access: yes, 2002
A new test method for evaluating the effects of shock vibration on concrete has been developed. In this method, shock vibrations are applied to prismatic specimens by hammering each specimen at one end in the longitudinal direction.

Deciphering Polarity Effects of Polymer to Regulate Li+ Ionic Environment in Solid Polymer Electrolytes for Solid‐State Lithium Batteries

open access: yesCarbon Energy, EarlyView.
We elucidate the fundamental influences of polymer polarity on Li+ ionic environments in solid polymer electrolytes by considering four critical components: Li+, FSI−, residual solvents, and polymer matrix. Beyond facilitating LiFSI dissociation and Li+ transport, our findings underscore previously overlooked roles of polymer polarity, thereby ...

Research on vibration pattern recognition based on phase‐sensitive optical time domain reflectometry and voting fully convolution neural networks

open access: yesIET Optoelectronics
A method that combines phase‐sensitive optical time domain reflectometry with deep learning to construct new voting fully convolution neural networks (VoteFCNs) is proposed. Compared to the traditional convolutional network, the VoteFCN can be input with

The Stabilization of High‐Nitrogen Systems: 10 Catenated Nitrogen Chain

open access: yesChemistry – A European Journal, EarlyView.
Improving the understanding of high‐nitrogen materials. ABSTRACT High‐nitrogen materials have attracted intense interest in recent decades due to their unique chemical, physical, and biological properties. Stabilizing high‐nitrogen materials is often challenging as they become more unstable with increasing nitrogen catenation and nitrogen mass ...

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.
