Gap Symmetry, Electronic Structure and Interplay Between Superconductivity and Spin Density Wave in Sr1−xKxFe2As2 Superconductor

Nano Select, EarlyView.
In moderately hole‐doped Sr1−xKxFe2As2${\rm Sr}_{1-x}{\rm K}_x{\rm Fe}_2{\rm As}_2$ system the pairing state is s+−${\rm s}^{+-}$ wave pairing state mediated by spin fluctuations. As the SDW order parameter increases, TC${\rm T}_C$ decreases and TM${\rm T}_M$ increases. As temperature increases, the SDW order parameter decreases and vanishes at TM${\rm

10-Commutators, 13-commutators and odd derivations

Journal of Nonlinear Mathematical Physics, 2008
Let \(X_1\), \dots, \(X_n\in Vect(n)\) be vector fields on a smooth manifold \(M\) of dimension \(n\) and define the \(N\)-commutator as \(s_N(X_1,\ldots,X_N)=\sum (-1)^\sigma X_{\sigma(1)}\ldots X_{\sigma(N)}\) where the summation runs over the symmetric group \(Sym_N\) and \((-1)^\sigma\) is the sign of the permutation \(\sigma\).

Robustness Assessment of Public Transport Networks in Various Graph Representations: Systematic Review, Decision Support, and Case Study

Networks, EarlyView.
ABSTRACT The analysis of certain properties of the underlying graph of a public transport network generates insights about the network's structure. Hereby, the choice of the graph representation depends on a trade‐off between complexity reduction and information preservation to adequately model a public transport network.

Enabling effective urban green space stewardship through planning: A qualitative comparative analysis in Southwest England

People and Nature, EarlyView.
Abstract Amid increasing urbanisation and biodiversity decline, ‘effective stewardship’ of urban green space (UGS) is a complex but critical nature‐based solution for long‐term environmental, social and economic gain. Combining stewardship and sense‐of‐place frameworks with European nature‐based solutions guidance, we investigate which social and ...

Wildland–urban interface expansion: Towards comprehensive planning processes

People and Nature, EarlyView.
Abstract Wildland–urban interface (WUI) expansion is accelerating in numerous regions around the world due to increasing amenity‐led migration processes, defined as the movement of people seeking higher environmental quality. While WUI areas are complex social–ecological systems requiring holistic planning and management, they are usually approached ...
