Unveiling Wasps as Potential Pollinators: Floral Traits and Wasp Sociality Intensify Network Centrality in a Highly Diverse Tropical Ecosystem

open access: yesJournal of Applied Entomology, Volume 149, Issue 10, Page 1520-1531, December 2025.
ABSTRACT Wasps, members of over 90 hymenopteran families, exhibit diverse behaviours, including pollination, predation and parasitism. While wasps are known pollinators in specialised systems, such as the intricate mutualism of fig trees and the deceptive pollination of certain orchids, they have historically been considered ineffective pollinators ...

Entanglement of a qubit coupled to a resonator in the adiabatic regime

open access: yes, 2005
We discuss the ground state entanglement of a bi-partite system, composed by a qubit strongly interacting with an oscillator mode, as a function of the coupling strenght, the transition frequency and the level asymmetry of the qubit.

Challenges and Opportunities in Combining Ultrasound and Inductive Coupling for Energy Supply and Bidirectional Data Exchange in Bioelectronics Medicine Implant Networks

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 11, November 2025.
In this contribution, it is shown that miniaturized nerve stimulation implants can be used in collaborative networks. Inductive links and ultrasound are combined to supply these implants with energy and data; the advantages and disadvantages of each method, as well as safety risks and possibilities for improvement are discussed and the best ...

Non-Commutative GUTs, Standard Model and C,P,T properties from Seiberg-Witten map

open access: yes, 2004
Noncommutative generalizations of Yang-Mills theories using Seiberg-Witten map are in general not unique. We study these ambiguities and see that SO(10) GUT, at first order in the noncommutativity parameter \theta, is unique and therefore is a truly ...
