Unified Scaling Law for Lengths of Basaltic Lava Flows: Dependence on Erupted Volume and Effusion Rate

open access: yesGeophysical Research Letters
Morphological scaling laws for basaltic lava flows, linking flow dimensions and eruption conditions, are essential for hazard assessment and geological analysis of basaltic eruptions.

Future Hydroclimatic Impacts on Africa: Beyond the Paris Agreement

open access: yesEarth's Future, 2019
Projections of global warming in Africa are generally associated with increasing aridity and decreasing water availability. However, most freshwater assessments focus on single hydroclimatic indicators (e.g., runoff, precipitation, or aridity), lacking ...

The Regime Shifts Database: a framework for analyzing regime shifts in social-ecological systems

open access: yesEcology and Society, 2018
Regime shifts, i.e., large, persistent, and usually unexpected changes in ecosystems and social-ecological systems, can have major impacts on ecosystem services, and consequently, on human well-being.

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long‐standing annotation error

open access: yesFEBS Open Bio, EarlyView.
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

Developing transformative schools : a resilience-focused paradigm for education [PDF]

open access: yes, 2014
For the better part of the past century, the field of education has witnessed repeated calls and initiatives for change, reform and improvement of our schools. Yet today, the problems of improving academic achievement and social adjustment among youth

Robustness-Driven Resilience Evaluation of Self-Adaptive Software Systems [PDF]

open access: yes, 2015
An increasingly important requirement for certain classes of software-intensive systems is the ability to self-adapt their structure and behavior at run-time when reacting to changes that may occur to the system, its environment, or its goals.

Directed evolution of enzymes at the crossroads of tradition and innovation

open access: yesFEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Resilience: A new integrative approach to health and mental health research [PDF]

open access: yes, 2008
We know from anecdote and research, science and art, that human resilience is a powerful, seemingly ubiquitous force. What is needed is a better understanding of the properties, variations, and applications of that concept to health and well-being.

Effects of random 3D upper crustal heterogeneity on long-period (≥ 1 s) ground-motion simulations

open access: yesEarth, Planets and Space, 2018
The effects of the short-wavelength heterogeneity of the crustal structure on predicted ground motion at periods of 1 s and longer were investigated by conducting three-dimensional finite-difference simulations using a detailed realistic velocity model ...

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

open access: yesFEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.
