Macroecological relationships of ant diversity with increasing aridity in Australian tropical savannas: contrasting responses of epigaeic and hypogaeic assemblages

open access: yesEcography, EarlyView.
Studies using climatic gradients play a key role in our understanding of the importance of rainfall and temperature as factors regulating species diversity and distribution, and thus of likely responses to climate change. However, such studies currently consider above‐ground species only, ignoring the diverse hypogaeic (subterranean) invertebrate fauna.

Enhanced Contribution of Biexciton‐Mediated Decay Kinetics in Perovskite Nanocrystals Via Sequential Ultrafast Excitation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sequential ultrafast excitation is shown to increase the relative kinetic weighting of biexciton‐mediated decay in CsPbBr3 nanocrystals without increasing the total excitation fluence. By temporally structuring excitation within the exciton lifetime, the early‐time fast decay contribution becomes more pronounced while the fitted fast decay constants ...

Governing Positive Energy Districts: The Role of Legitimation and Identity Across Residential and Industrial Contexts

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Increasing electricity demand from data centres, industrial applications, electric vehicles and domestic heating is creating pressure to develop electricity systems in many parts of the world, but especially in Western countries. In response to challenges such as grid congestion, interconnection queues and climate‐related hazards, network ...

Toward Comprehensive Climate Action: Assessing Mitigation Approaches Across Canadian Municipalities

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Local governments are widely regarded as key leaders in the global response to climate change. Understanding if and how municipalities commit to climate mitigation is crucial for assessing their contribution to global emission‐reduction goals and identifying barriers to effective climate transitions.

"Faire" école ?

open access: yes, 2015
Une école peut désigner une unité de lieu, de temps, mais aussi une unité de doctrine ou encore un style (de pensée mais aussi de vie). Dans le cas des Sciences humaines et sociales, une « école » est ce qui rassemble des personnes et des travaux sous ...

Design, Synthesis, and Photophysical Studies of Functionalized Polyaromatic Isonitriles as Visible Light Photoredox Catalysts

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A new series of structurally rich polyaromatic isonitriles is presented as photoredox catalysts. Their photophysical properties are investigated by UV–Vis absorption and fluorescence measurements, combined with experimental and theoretical studies to evaluate both ground‐ and excited‐state redox properties.

Applied Element Modelling of Out‐Of‐Plane Instability in Boundary Elements of Thin RC Walls

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Recent earthquakes in Chile (2010) and New Zealand (2011) caused extensive damage to buildings featuring reinforced concrete (RC) structural walls, with observed failure modes including out‐of‐plane instability of slender walls. This buckling‐type response under combined in‐plane and out‐of‐plane loading has also been documented in ...

Subspace Acceleration for Efficient Nonlinear Water Wave Simulation

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
We introduce an exponentially weighted subspace acceleration technique to reduce GMRES iterations for solving the Poisson equation with time‐dependent coefficients in nonlinear, dispersive free‐surface flows governed by the incompressible Navier‐Stokes equations. The method significantly reduces memory requirements and computational complexity compared
