Timescales and contribution of heating and helicity effect in helicity‐dependent all‐optical switching

open access: yesRare Metals, Volume 42, Issue 1, Page 234-243, January 2023., 2023
Graphical abstract Abstract The heating and helicity effects induced by circularly polarized laser excitation are entangled in the helicity‐dependent all‐optical switching (HD‐AOS), which hinders understanding the magnetization dynamics involved. Here, applying a dual‐pump laser excitation, first with a linearly polarized (LP) laser pulse followed by a

Policy beliefs, policy learning, and risk perception: Exploring the formation of local creative Placemaking‐catalyzed policy network

open access: yesReview of Policy Research, Volume 40, Issue 1, Page 153-175, January 2023., 2023
Abstract This article studies the formation of a local Creative Placemaking (CPM) policy network based on the Advocacy Coalition Framework (ACF) and social capital perspective of policy networks. This article hypothesizes that policy beliefs, policy learning, social capital, and the perceived risks induced by defections, as well as macro‐level changes ...

Characterization of Retained Austenite in Advanced High‐Strength Steel

open access: yesScanning, Volume 2023, Issue 1, 2023., 2023
The retained austenite (RA) in advanced high‐strength steels directly affects their plasticity. It is very important for the accurate characterization of their content and types. This paper prepared three specimens with three different Mn contents (1.0%, 1.4%, and 1.7%) that are used to obtain high‐strength steel by ultrafast cooling heat treatment ...

Beyond Growth Machine Politics: Understanding State Politics and National Political Mandates in China’s Urban Redevelopment

open access: yesAntipode, Volume 54, Issue 2, Page 608-628, March 2022., 2022
Abstract Large‐scale demolition has been ubiquitous in fast urbanising China. The politics of redevelopment is often seen as secondary, derived from and defined by local entrepreneurial governance. However, changing state politics, in particular national political mandates, has not been adequately addressed. Through examining variegated practices, this

Effects of the Addition of Nb and V on the Microstructural Evolution and Hydrogen Embrittlement Resistance of High Strength Martensitic Steels

open access: yesScanning, Volume 2022, Issue 1, 2022., 2022
Hydrogen embrittlement can easily occur in high strength martensitic steel, manifesting itself as a sudden failure or fracture without warning and greatly threatening the safety of automotive applications. Optimizing the composition of the alloy can be performed by matching heat treatment processing methods and controlling the precipitation amounts to ...

EasyDCP: An affordable, high‐throughput tool to measure plant phenotypic traits in 3D

open access: yesMethods in Ecology and Evolution, Volume 12, Issue 9, Page 1679-1686, September 2021., 2021
Abstract High‐throughput 3D phenotyping is a rapidly emerging field that has widespread application for measurement of individual plants. Despite this, high‐throughput plant phenotyping is rarely used in ecological studies due to financial and logistical limitations.

Computer‐Aided Rapid Establishment of Fingerprint of Xiaojin Capsule by HPLC

open access: yesInternational Journal of Analytical Chemistry, Volume 2021, Issue 1, 2021., 2021
Traditional Chinese medicine (TCM) formulas have a significant clinical efficacy, and the fingerprint technology has been widely accepted to fully reveal the quality of TCM. Whereas, it is a great challenge to establish the fingerprint chromatogram which can fully reflect every single herb material in a short time.

Historical and contemporary indigenous marine conservation strategies in the North Pacific

open access: yesConservation Biology, Volume 34, Issue 1, Page 5-14, February 2020., 2020
Abstract Strategies to reduce, halt, and reverse global declines in marine biodiversity are needed urgently. We reviewed, coded, and synthesized historical and contemporary marine conservation strategies of the Kitasoo/Xai'xais First Nation in British Columbia, Canada to show how their approaches work.
