Effects of non-linearities and disorder in systems with multiple absorbing states. A perspective for modeling the dynamics of complex ecosystems. [PDF]

open access: yes, 2013
Interacting particle systems are a particular class of stochastic processes where single degrees of freedom interact through probabilistic rules defined over a graph which reflects the spatial topology of the model.

Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

open access: yesAdvanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

Carbon cycling and POC turnover in the mesopelagic zone of the ocean: Insights from a simple model [PDF]

open access: yes, 2010
Carbon budgets of the mesopelagic zone are poorly constrained, highlighting our lack of understanding of the biota that inhabit this environment and their role in the cycling and sequestering of carbon in the deep ocean.

Comparing the Fate of eDNA by Particle Sizes and Molecule Lengths in Recirculating Streams

open access: yesEnvironmental DNA
The detection of environmental DNA (eDNA) has revolutionized aquatic species monitoring, yet interpreting eDNA data remains challenging due to gaps in our understanding of eDNA ecology (i.e., origin, state, transport, and fate) and variability in how ...

Soil Viruses Are Underexplored Players in Ecosystem Carbon Processing

open access: yesmSystems, 2018
Rapidly thawing permafrost harbors ∼30 to 50% of global soil carbon, and the fate of this carbon remains unknown. Microorganisms will play a central role in its fate, and their viruses could modulate that impact via induced mortality and metabolic ...
