Trade Uncertainty, Economic Policy Uncertainty and Shipping Costs

open access: yesGerman Economic Review
Abstract We examine how trade and policy uncertainty affect shipping freight rates, using a Bayesian Vector Autoregression (BVAR) model. Trade uncertainty has a strong effect on shipping costs, even though the effects become insignificant within a year.

Facing Uncertainty in Cyber Insurance Policies

open access: yes, 2017
Cyber insurance has gained less ground in Europe than in the U.S., but with emerging laws and regulations, the prospect of considerable fines for security breaches is pushing many organisations into this market. A qualitative interview study in Norway reveals the main uncertainty factors for organisations that have little experience with the cyber ...

Autonomous Navigation of Pollen‐Inspired Magnetic Microrobots for Biomedical Applications

open access: yesAdvanced Robotics Research, EarlyView.
A sunflower pollen‐inspired magnetic microrobot enables controlled rolling navigation in vessel‐like environments. Its open geometry reduces hydrodynamic drag, while vision‐based closed‐loop control, shortest‐path planning, and reinforcement learning support target‐reaching and maze navigation with microrobot‐scale accuracy, highlighting a route toward

Consensus Formation and Change are Enhanced by Neutrality

open access: yesAdvanced Science, EarlyView.
Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.

Prior Expectations Bias Confidence Judgments Through Parietal Alpha‐Band Modulation

open access: yesAdvanced Science, EarlyView.
ABSTRACT Humans possess the metacognitive ability to estimate the likely accuracy of their own decisions through confidence judgments. Yet, whether prior information shapes confidence and the neural mechanisms mediating such influence, remain to be determined.

Firm-level climate policy uncertainty perception and the cost of equity capital: evidence from textual analysis

open access: yesJournal of Applied Economics
We construct a new firm-level climate policy uncertainty perception using textual data from the annual reports of Chinese listed firms, and investigate the effect of climate policy uncertainty perception on the cost of equity capital.

ML Workflows for Screening Degradation‐Relevant Properties of Forever Chemicals

open access: yesAdvanced Science, EarlyView.
The environmental persistence of per‐ and polyfluoroalkyl substances (PFAS) necessitates efficient remediation strategies. This study presents physics‐informed machine learning workflows that accurately predict critical degradation properties, including bond dissociation energies and polarizability.

From Ambition to Action: Barriers and Enablers for the Inclusion of Indigenous Peoples and Local Communities in the Kunming–Montreal Biodiversity Framework and the Role of Non‐State Bridge Organizations

open access: yesAdvanced Science, EarlyView.
Graphical abstract illustrating the transition from global biodiversity ambition to on‐the‐ground implementation of the Kunming–Montreal Global Biodiversity Framework after COP16, highlighting the roles of governments, non‐state actors, scientific knowledge systems, and resource mobilization in achieving transformative biodiversity outcomes.

Ethical Precision in Nanoscale Brain Interfacing

open access: yesAdvanced Science, EarlyView.
As brain interfaces approach the nanoscale, precision no longer only measures—it knows, predicts, and potentially reshapes the mind. This work argues that traditional ethics fails under such conditions and proposes a shift toward continuous, operation‐based governance using the recovery–discovery framework to track, constrain, and responsibly steer ...
