A Statistical Social Network Model for Consumption Data in Food Webs

, 2013
We adapt existing statistical modeling techniques for social networks to study consumption data observed in trophic food webs. These data describe the feeding volume (non-negative) among organisms grouped into nodes, called trophic species, that form the

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Perceptible climate warming amplifies how education increases climate concern in the US

npj Climate Action
Among the strongest predictors of climate change awareness in the US, outside partisan filters, is education level. Here we show how, in the US, perceptible climate warming increased the effect that education has on climate concerns.

Burial practices and social complexity: Jomon examples

Documenta Praehistorica, 2011
Many archaeologists investigated the burial practices of the Jomon in order to clarify emerging social complexity, especially in the 1950s. Recently, since the social complexity of the Jomon became an important issue, burial practice has been recognised ...

From Simple to Complex and Ultra-complex Systems:\ud A Paradigm Shift Towards Non-Abelian Systems Dynamics [PDF]

, 2010
Atoms, molecules, organisms distinguish layers of reality because of the causal links that govern their behavior, both horizontally (atom-atom, molecule-molecule, organism-organism) and vertically (atom-molecule-organism).

Complexity and Social Decision Rules [PDF]

1977 IEEE Conference on Decision and Control including the 16th Symposium on Adaptive Processes and A Special Symposium on Fuzzy Set Theory and Applications, 1977
This paper attempts to show how a particular concept and measure of complexity, as derived from automata theory, can be meaningfully interpreted in a program of 'limited rationality' regarding individual or social choices. The complexity measure appears to be a natural consequence of looking at a decision rule as a finite-state machine that computes ...

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
