Allostery without conformation change: modelling protein dynamics at multiple scales.
The original ideas of Cooper and Dryden, that allosteric signalling can be induced between distant binding sites on proteins without any change in mean structural conformation, has proved to be a remarkably prescient insight into the rich structure of protein dynamics. It represents an alternative to the celebrated Monod-Wyman-Changeux mechanism and proposes that modulation of the amplitude of ...
متن کاملIndividual contributions of climate and vegetation change to soil moisture trends across multiple spatial scales
Climate and vegetation change are two dominating factors for soil moisture trend. However, their individual contributions remain unknown due to their complex interaction. Here, I separated their contributions through a trajectory-based method across the global, regional and local scales. Our results demonstrated that climate change accounted for 98.78% and 114.64% of the global drying and wetti...
متن کاملAutomating woody vegetation change detection at regional scales: the problem of clouds and cloud shadows
This paper presents a semi-automated cloud and cloud shadow masking method, developed for SPOT5 satellite data over New South Wales (NSW), Australia. As clouds are very similar to several surface features in these data, attempts at using traditional image classification techniques have not been effective. The new method uses morphological feature extraction, where marker pixels are identified u...
متن کاملBiogeophysical feedbacks trigger shifts in the modelled vegetation-atmosphere system at multiple scales
Terrestrial vegetation influences climate by modifying the radiative-, momentum-, and hydrologicbalance. This paper contributes to the ongoing debate on the question whether positive biogeophysical feedbacks between vegetation and climate may lead to multiple equilibria in vegetation and climate and consequent abrupt regime shifts. Several modelling studies argue that vegetation-climate feedbac...
متن کاملChanges at Multiple Spatial Scales
Change detection on rasterized data is extremely dependent on accurate radiometric and geometric rectification. The development of processing tools able to minimise these requirements has been recognised since the late eighties. In the present paper we present a methodology for detecting changes on multidate satellite images with different radiometric and geometric characteristics via Multireso...
