Exploring Quantum Control Landscape Structure [PDF]

open access: yesPhysical Review A, 2013
A common goal of quantum control is to maximize a physical observable through the application of a tailored field. The observable value as a function of the field constitutes a quantum control landscape.

Effects of habitat composition and landscape structure on worker foraging distances of five bumblebee species [PDF]

open access: yesEcological Applications, 2016
Bumblebees (Bombus spp.) are important pollinators of both crops and wild flowers. Their contribution to this essential ecosystem service has been threatened over recent decades by changes in land use, which have led to declines in their populations.

Redefining Landscape Structure for Ecosystem Services [PDF]

open access: yesCurrent Landscape Ecology Reports, 2016
Our understanding of the effects of landscape structure on ecosystem services (ES) remains at a very early stage, despite a large body of literature on the effects of the composition and configuration of natural land cover on some ES. Here, I argue that a comprehensive understanding of the effects of landscape structure on ES requires us to reconsider ...

Landscape structure influences urban vegetation vertical structure [PDF]

open access: yesJournal of Applied Ecology, 2016
Summary Vegetation vertical structure is important for biodiversity and ecosystem service provision. In cities, however, while variation in the spatial extent and distribution of vegetation has been widely investigated, vertical vegetation structure and its potential drivers have not.

Determining the Relationship Between Landscape Structure and Mental Components on Thermal Assessment [PDF]

open access: yesJournal of Advances in Environmental Health Research, 2021
Background: The urban open spaces and their effects on the physical and mental health highlights the attention on the quality of such spaces. Thermal comfort is an environmental component affecting the reactionary behavior of people in these spaces.

Structural Landscapes in Geometrically Frustrated Smectics [PDF]

open access: yesPhysical Review Letters, 2021
A phenomenological free energy model is proposed to describe the behavior of smectic liquid crystals, an intermediate phase that exhibits orientational order and layering at the molecular scale. Advantageous properties render the functional amenable to numerical simulation.

Energy Landscapes for Electronic Structure [PDF]

open access: yesJournal of Chemical Theory and Computation, 2020
Orbital-optimized multiple self-consistent-field (SCF) solutions are increasingly being interpreted as mean-field approximations of diabatic or excited electronic states. However, surprisingly little is known about the topology of the electronic energy landscape from which these multiple solutions emerge.

Connectivity, landscape structure, and plant diversity across agricultural landscapes: novel insight into effective ecological network planning.

open access: yesJournal of Environmental Management, 2022
Natural habitats in rural and urban areas are increasingly fragmented and altered by human impacts that are limiting the animal and plant dispersal process. Fragmentation and isolation can be reversed by restoring landscape connectivity through effective

Modelling the Impacts of Habitat Changes on the Population Density of Eurasian Skylark (Alauda arvensis) Based on Its Landscape Preferences

open access: yesLand, 2021
The dramatic decline of the abundance of farmland bird species can be related to the level of land-use intensity or the land-cover heterogeneity of rural landscapes.

Examining the Influence of Landscape Patch Shapes on River Water Quality

open access: yesLand, 2023
River water quality can be affected by a range of factors, including both point and non-point sources of pollution. Of these factors, changes in land use and land cover are particularly significant, as they can alter the structure of the landscape and ...
