Global Biogeographical Pattern of Ecosystem Functional Types Derived From Earth Observation Data

open access: yesRemote Sensing, 2013
The present study classified global Ecosystem Functional Types (EFTs) derived from seasonal vegetation dynamics of the GIMMS3g NDVI time-series. Rotated Principal Component Analysis (PCA) was run on the derived phenological and productivity variables ...

Decoding the dynamic extracellular matrix in cancer—3D models and bioscaffolds rewire the rules of tumor progression

open access: yesFEBS Letters, EarlyView.
Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Local and Regional Scale Heterogeneity Drive Bacterial Community Diversity and Composition in a Polar Desert

open access: yesFrontiers in Microbiology, 2018
The distribution of organisms in an environment is neither uniform nor random but is instead spatially patterned. The factors that control this patterning are complex and the underlying mechanisms are poorly understood.

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Construction of a Coupling Framework for Production-Living-Ecology Function Interactions: A Case Study of the Guizhou-Guangxi Karst Region, Southwest China

open access: yesLand
Karst regions face acute conflicts among production, living, and ecology (PLE) functions under the constraints of rugged terrain and rocky desertification. Existing studies have separately examined driving factors, interaction directions and intensities,

Analysis of urban sprawl at mega city Cairo, Egypt using multisensoral remote sensing data, landscape metrics and gradient analysis [PDF]

open access: yes, 2009
This paper is intended to highlight the capabilities of synergistic usage of remote sensing, landscape metrics and gradient analysis. We aim to improve the understanding of spatial characteristics and effects of urbanization on city level ...

Childhood conscientiousness predicts the social gradient of smoking in adulthood: a life course analysis. [PDF]

open access: yes, 2015
The social gradient in smoking is well known, with higher rates among those in less advantaged socioeconomic position. Some recent research has reported that personality characteristics partly explain this gradient. However, the majority of existing work

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Spatial Analysis of Astragalus verus Olivier Dieback: Understanding Patterns and Implications for Conservation in Iranian Rangelands

open access: yesEcology and Evolution
Astragalus verus Olivier, a species native to Iran, is experiencing dieback, particularly in the Zagros and Central Iran regions. This study examines whether dieback patterns are spatially non‐random and influenced by soil conditions.
