The Book as a landscape [PDF]

open access: yes, 2011
There is a long tradition of regarding landscapes as texts and texts as landscapes. Characterizing visually experienced nature as a text implies stressing its meaningfulness, its character as a message or an expression.

Exploring constrained quantum control landscapes [PDF]

open access: yes, 2012
The broad success of optimally controlling quantum systems with external fields has been attributed to the favorable topology of the underlying control landscape, where the landscape is the physical observable as a function of the controls.

Reduced vascular leakage correlates with breast carcinoma T regulatory cell infiltration but not with metastatic propensity

open access: yesMolecular Oncology, EarlyView.
A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

Perception of native grasslands in south-eastern Australia: some implications for landscape aesthetics and other landscape values [PDF]

open access: yes, 2001
Grasslands are considered to be Australia’s most threatened ecosystems, yet relatively little is known about human preferences and attitudes which contribute to continued degradation of these landscapes.

The Statistics of the Number of Minima in a Random Energy Landscape

open access: yes, 2006
We consider random energy landscapes constructed from d-dimensional lattices or trees. The distribution of the number of local minima in such landscapes follows a large deviation principle and we derive the associated law exactly for dimension 1. Also of

A Comparison of Machine-Learning Methods to Select Socioeconomic Indicators in Cultural Landscapes [PDF]

open access: yes, 2018
Cultural landscapes are regarded to be complex socioecological systems that originated as a result of the interaction between humanity and nature across time. Cultural landscapes present complex-system properties, including nonlinear dynamics among their

Liquid biopsy epigenetics: establishing a molecular profile based on cell‐free DNA

open access: yesMolecular Oncology, EarlyView.
Cell‐free DNA (cfDNA) fragments in plasma from cancer patients carry epigenetic signatures reflecting their cells of origin. These epigenetic features include DNA methylation, nucleosome modifications, and variations in fragmentation. This review describes the biological properties of each feature and explores optimal strategies for harnessing cfDNA ...

Evolutionary Dynamics and Optimization: Neutral Networks as Model-Landscapes for RNA Secondary-Structure Folding-Landscapes

open access: yes, 1995
We view the folding of RNA-sequences as a map that assigns a pattern of base pairings to each sequence, known as secondary structure. These preimages can be constructed as random graphs (i.e. the neutral networks associated to the structure $s$).

Identifying "communities" within energy landscapes

open access: yes, 2004
Potential energy landscapes can be represented as a network of minima linked by transition states. The community structure of such networks has been obtained for a series of small Lennard-Jones clusters.

The landscapes of tourism space [PDF]

open access: yes, 2009
The author attempts to define the term ‘tourism landscape’. It is treated as an important attribute of tourism space therefore, apart from its definition, the author presents its characteristic features and various types of such spaces with differing ...
