Comfort in the canopy: How urban treescapes affect human thermal comfort in a temperate climate

open access: yesPeople and Nature, EarlyView.
Abstract People living in urban centres are exposed to higher levels of heat stress than those living outside of these areas; this is intensified by the urban heat island effect. Heat stress is a concern for the more vulnerable members of society and can exacerbate many medical conditions; excessive heat increases morbidity and mortality rates.

Impact of polymer aging on main‐chain poly(fullerene)s with halide chain‐ends for inverted perovskite solar cells

open access: yesPolymer International, EarlyView.
Subtle variations in halogen chemistry significantly affect the aging behavior of polymeric electron transport layers in inverted perovskite solar cells, underscoring the importance of precise chemical design for enhancing long‐term stability. Abstract As perovskite solar cells (PSCs) advance toward commercialization, the need for stable and easily ...

Computational design of poly(p‐phenylene vinylene)‐based gas sensors: tunable reactivity and selectivity via side‐group functionalization

open access: yesPolymer International, EarlyView.
Side‐group functionalization enhances the reactivity and optoelectronic properties of poly(p‐phenylene vinylene) (PPV) derivatives for chemical sensing. PPV‐CN and PPV‐NO2 display strong interactions and pronounced responses, providing molecular‐level insights for designing high‐performance polymer‐based sensors.

Anisotropic Diffuse Radiation Model of Photovoltaic Systems

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Monthly incident diffuse energy—isotropic and anisotropic models. ABSTRACT The diffuse solar radiation is a component of the global solar radiation and may contribute a significant percentage (50% and above in some locations) of the electric output energy of Photovoltaic (PV) systems.

Permafrost Distribution in the Canadian Rockies: Key Variables Influencing Patch‐Scale Variability

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The spatial distribution of permafrost in mountainous regions is influenced by various factors such as topography, climate, vegetation, and substrate. Despite the existence of comprehensive permafrost maps at national and global levels, they fail to accurately represent the patch‐scale (e.g., < 25 m) permafrost distribution in characteristic ...

Realistic natural atmospheric phenomena and weather effects for interactive virtual environments.

open access: yes
Clouds and the weather are important aspects of any natural outdoor scene, but existing dynamic techniques within computer graphics only offer the simplest of cloud representations. The problem that this work looks to address is how to provide a means of

A Statistical‐Process Hybridized Approach to Modeling Permafrost Distribution in a Boreal Wetland Ecosystem, Whatì, NT, Canada

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT High‐resolution mapping of permafrost in ecologically and topographically complex landscapes remains a major challenge. Existing models of permafrost extent often rely on equilibrium assumptions, which can misrepresent conditions in regions where permafrost persists largely due to ecosystem structure.
