Indoor UAV for Nuclear Investigation: Experimental Qualification and Field Feedback

Journal of Field Robotics, EarlyView.
ABSTRACT Indoor Unmanned Aerial Vehicles (UAVs) have recently gained interest for inspection and investigation tasks in hazardous environments. In the nuclear field, indoor UAVs offer promising capabilities to reduce workers' exposure to ionizing radiation while accessing confined or elevated areas.

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

A Fuzzy Fusion Method for Multi-Ship Collision Avoidance Decision-Making with Merchant and Fishing Vessels

Journal of Marine Science and Engineering
In multi-vessel collision avoidance decision-making, the collision between merchant and fishing vessels is a significant challenge. This paper proposes a fuzzy fusion method for making avoidance decisions under the influence of the navigation environment.

Sino‐Mexican Encounters Before the ‘Diplomatic Opening’: Exhibition Diplomacy and Grassroots Friendship in the 1960s

History, EarlyView.
Abstract During the 1960s, Mexico's Institutional Revolutionary Party (PRI) embraced Chinese overtures for a commercial opening as consistent with its anti‐imperialist posture, thereby foreshadowing the diplomatic opening to China in 1972. Yet this professed ideological pluralism was eclipsed by an underlying allegiance to the United States' anti ...
