Advanced Science, EarlyView.This study employs a spouse‐pair cohort design and an idopNetwork model that integrates evolutionary game theory, predator‐prey dynamics, and developmental modularity theory to reconstruct maximally informative microbial interaction networks. This approach reveals how interspecies interactions drive the phenotypic plasticity of the gut microbiota in ...

Spectroscopy of the symbiotic binary CH Cygni from 1996 to 2007 [PDF]
Astronomy & Astrophysics, 2009 We monitored a set of emission lines in the optical spectra of CH Cyg using the 1.5-m telescope at the Tartu Observatory, Estonia. Most of the spectra were registered in the H alpha region, but other Balmer lines and lines of He, N, O, and Fe were also investigated in terms of their equivalent widths, radial velocities, and absolute fluxes. The spectra

Empowering Circular Startups: Unveiling the Blueprint for Circular Business Models
Business Strategy and the Environment, EarlyView.ABSTRACT Circular startups are increasingly recognized as key drivers in the transition toward a circular economy. Yet the business models (BMs) through which these startups operationalize circularity remain poorly understood, limiting the ability of entrepreneurial ecosystem actors to offer effective support.
