Climate assemblies involving children and youth as socio‐educational spaces: Perceived success factors, challenges and opportunities

British Educational Research Journal, EarlyView.
Abstract Climate assemblies have emerged as participatory mechanisms and as socio‐educational spaces for engaging citizens in climate decision‐making and promoting sustainability learning. However, to date, initiatives involving children and young people remain underexplored.

Introduction of a Double‐Headed Nucleotide Into G‐Quadruplex DNA: Position‐Dependent Stabilization and Structural Insights

Chemistry – A European Journal, EarlyView.
A double‐headed bis‐guanine (G) nucleotide (GG) was evaluated as a noncanonical building block in G‐quadruplexes (G4s). Biophysical and computational analyses reveal that GG can directly participate in G‐tetrads and strongly stabilize G4s in a position‐ and topology‐dependent manner. These findings establish design rules for using GG to engineer highly

Differential sensitivity to SHH signaling and neural crest‐mediated Gas1 expression regulate jaw size during development and evolution

Developmental Dynamics, EarlyView.
Abstract Background Developmental control of jaw size is crucial to prevent birth defects and facilitate evolutionary adaptation. We have shown that jaw size is established by neural crest mesenchyme (NCM), which are progenitor cells that migrate into the mandibular primordia and produce the jaws.

A note on the distance of ladder height distributions

Stochastic Processes and their Applications, 1986
Let \(S_ 0=0\), \(S_ 1,S_ 2,..\). be a random walk with step distribution \(\mu\), let \(\mu_+\) denote the (possibly defective) distribution of the first ascending ladder height \(Y_+:\) \(Y_+=S_{\tau_+}\) on \(\{\tau_+0:\) \(S_ n>0\}\) (inf \(\emptyset =\infty).\) Given two such processes with step distributions \(\mu_ 1\) and \(\mu_ 2\) respectively

Comparative analysis of engineering solutions against the shift of the upper part of the ladder when performing work at height

SAFETY OF TECHNOGENIC AND NATURAL SYSTEMS, 2021
Introduction. Modern construction is characterized by work at a height using stairs. The article presents various engineering solutions aimed at preventing injuries during such work. Problem Statement. The objective of this study is to compare the available engineering solutions aimed at preventing the upper part of the ladder from shifting when ...

Electronic Structure Modulation in Dopant‐Controlled Single‐Atom Graphene Catalysts for Efficient Hydrogen Evolution: A Machine Learning and First‐Principles Study

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
First‐principles DFT calculations and machine learning analysis show that heteroatom doping of graphene (G) significantly enhances the stabilization of transition‐metal single atoms by strengthening metal–support interactions and increasing charge transfer. N‐doped G exhibits higher adsorption energies, lower d‐band centers, and shorter TM–G bonds than

Study on Roof‐Control Technology for Gob‐Side Entry Retaining Under Composite Roofs

Energy Science &Engineering, EarlyView.
This study develops a roof‐control technology system for gob‐side entry retaining under composite roofs. By integrating field measurements, theoretical analysis, and numerical simulation, it reveals the spatiotemporal evolution of the plastic zone and proposes a targeted support method, providing theoretical and practical guidance for safe and ...

‘The most advanced outpost of cultivation’: palynological evidence for cereal agriculture and population resilience in a marginal upland environment

Journal of Quaternary Science, EarlyView.
ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...
