Guano-Derived Nutrient Subsidies Drive Food Web Structure in Coastal Ponds. [PDF]

open access: yesPLoS ONE, 2016
A stable isotope study was carried out seasonally in three coastal ponds (Marinello system, Italy) affected by different gull guano input to investigate the effect of nutrient subsidies on food web structure and dynamics. A marked 15N enrichment occurred

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

A simplified stability analysis method for LV inverter-based microgrids

open access: yesJournal of Modern Power Systems and Clean Energy, 2019
This paper presents a simplified small-signal stability analysis method for low voltage (LV) inverter-based microgrids, in a generalized manner. The simplification is based on a simplified microgrid structure that relies on dominating inverter coupling ...
