Could botanic gardens use the Plant Treaty to regulate plant exchanges?

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Current international laws surrounding accessing and sharing biological materials in botanic gardens is limiting their capacity to conserve, research, educate and raise public awareness about biodiversity. We set out an argument for using the access and benefit sharing arrangements of the International Treaty for Plant Genetic Resources for Food and ...

Relational Bundle Geometric Formulation of Non‐Relativistic Quantum Mechanics

open access: yesFortschritte der Physik, EarlyView.
Abstract A bundle geometric formulation of non‐relativistic many‐particles Quantum Mechanics is presented. A wave function is seen to be a C$\mathbb {C}$‐valued cocyclic tensorial 0‐form on configuration space‐time seen as a principal bundle, while the Schrödinger equation flows from its covariant derivative, with the action functional supplying a ...

The role of identification in data‐driven policy iteration: A system theoretic study

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...
