Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens

PLANTS, PEOPLE, PLANET, EarlyView.
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

A Study on Preventing Thermal Runaway of Contaminated Ammonium Nitrate Prill in Bulk Storage

Propellants, Explosives, Pyrotechnics, EarlyView.
Schematic illustration of a contaminated region of ammonium nitrate prill undergoing exothermic decomposition, producing gases containing NOx. The interstitial flow of these heated gases rapidly raises the temperature of ammonium nitrate along the flow path.

Unveiling Hidden Features of Strongly Correlated Quantum Systems Through a Complex‐Network Analysis

Advanced Quantum Technologies, EarlyView.
By applying complex network theory, we report a fundamental and previously unobserved phenomenon in the finite‐size Kitaev model: a singular point at which uniform, nonzero entanglement emerges among all fermion pairs, forming a complete entanglement network.

Loss Behavior in Supervised Learning With Entangled States

Advanced Quantum Technologies, EarlyView.
Entanglement in training samples supports quantum supervised learning algorithm in obtaining solutions of low generalization error. Using analytical as well as numerical methods, this work shows that the positive effect of entanglement on model after training has negative consequences for the trainability of the model itself, while showing the ...

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

International 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 ...
