Cabomba caroliniana and Schoenoplectus californicus as Antifouling Candidates: Anti‐Attachment and Toxicological Effects in Aurelia coerulea (Cnidaria, Scyphozoa)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Biofouling on artificial surfaces in aquatic ecosystems leads to significant economic losses. Current antifouling paints, while effective, often harm the aquatic environment. This study explores ecologically safe antifouling alternatives derived from plants, focusing on the aquatic macrophytes Cabomba caroliniana (CC) and Schoenoplectus ...

Metamorphosys [PDF]

open access: yes, 2007
Viele Anwendungen im Bereich der eingebetteten Systeme erfordern hohe Rechenleistung und eine zeitnahe Anpassung an sich ändernde Umgebungsbedingungen. Hierfür eignen sich adaptive Systeme, die neben der Flexibilität durch Software eine Anpassung der System-Hardware erlauben. In dieser Arbeit wurde ein hardware-basierter Adaptionsansatz untersucht, der

Dynamic Neural‐Model‐Based Predictive Control for Autonomous Wheel‐Legged Robot System

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Mobile wheel‐legged robots exhibiting mobility, stability and reliability have garnered heightened research attention in demanding real‐world scenarios, especially in material transport, emergency response and space exploration. The kinematics model merely delineates the geometric relationship of the controlled objective, disregarding force ...

Many roads to reservoirs? How susceptibility and shedding shape host competence in amphibians

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Host competence—the ability to acquire, harbour and transmit infections—drives pathogen spread and persistence in multi‐host communities. Evaluating species‐specific competence is critical for predicting transmission, particularly for generalist fungal pathogens like ...

Climate stability drives multidimensional nestedness of amphibian assemblages in a Chinese sky island system

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

A late-time transition in the equation of state versus Lambda-CDM

open access: yes, 2002
We study a model of the dark energy which exhibits a rapid change in its equation of state w(z), such as occurs in vacuum metamorphosis. We compare the model predictions with CMB, large scale structure and supernova data and show that a late-time ...
