Comparative analysis of ephemeral river ecosystem services in agricultural and natural landscapes in mediterranean environments. A practical approach to Caia River (Portugal) [PDF]

open access: yes, 2019
Mediterranean landscapes present a large amount of biodiversity and ecosystems leading to their unique identity. In fact, it is increasingly acknowledged that these ecosystems provide a large range of benefits, not only for the area where they are ...

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

Optically induced potential energy landscapes [PDF]

open access: yes, 2007
Multi-dimensional potential energy surfaces are associated with optical binding. A detailed exploration of the available degrees of geometric freedom reveals unexpected turning points, producing intricate patterns of local force and torque.

Tonic signaling of the B‐cell antigen‐specific receptor is a common functional hallmark in chronic lymphocytic leukemia cell phosphoproteomes at early disease stages

open access: yesMolecular Oncology, EarlyView.
B‐cell chronic lymphocytic leukemia (B‐CLL) and monoclonal B‐cell lymphocytosis (MBL) show altered proteomes and phosphoproteomes, analyzed using mass spectrometry, protein microarrays, and western blotting. Identifying 2970 proteins and 316 phosphoproteins, including 55 novel phosphopeptides, we reveal BCR and NF‐kβ/STAT3 signaling in disease ...

Multi-tier archetypes to characterise British landscapes, farmland and farming practices

open access: yesEnvironmental Research Letters, 2022
Due to rising demand for both food and environmental services, agriculture is increasingly required to deliver multiple outcomes. Characterising differences, across agricultural landscapes, via the identification of broad archetypal groupings, is an ...

Mass‐flowering crops dilute pollinator abundance in agricultural landscapes across Europe

open access: yesEcology Letters, 2016
Mass‐flowering crops (MFCs) are increasingly cultivated and might influence pollinator communities in MFC fields and nearby semi‐natural habitats (SNHs).

Forest views: Northeast Oregon survey looks at community and environment [PDF]

open access: yes, 2012
This brief reports on a survey conducted in fall 2011 as one component of the ongoing Communities and Forests in Oregon (CAFOR) project. The CAFOR project focuses on the people and landscapes of three counties in northeast Oregon (Baker, Union, and ...

Complex-network analysis of combinatorial spaces: The NK landscape case

open access: yes, 2012
We propose a network characterization of combinatorial fitness landscapes by adapting the notion of inherent networks proposed for energy surfaces. We use the well-known family of NK landscapes as an example. In our case the inherent network is the graph

Expression and DNA methylation of 20S proteasome subunits as prognostic and resistance markers in cancer

open access: yesMolecular Oncology, EarlyView.
Comprehensive analysis of genomic mutations, gene expression, DNA methylation, and pathway analysis of TCGA data was carried out to define cancer types in which proteasome subunits expression is associated with worse survival. Albeit the effect of specific proteasome subunits on cellular function, the main role of the proteasome is better evaluated ...

Concepts and definitions of health and health-related values in the knowledge landscapes of the digital society

open access: yesCroatian Medical Journal, 2017
The knowledge landscapes (http://knowledge-landscapes. hiim.hr/) represent multidimensional environments, which individuals encounter when searching for knowledge, particularly, knowledge related to health (1,2).
