The authors describe three recent experiences of epidemiological surveys of zoonotic diseases in Brazil. The role of spatial data acquisition and analysis has been reinforced, considering the intrinsic complexity of environmental and social factors affecting transmission. Health surveillance in Brazil is undergoing a decentralisation process, in accordance with which different responsibilities are attributed to each health institution, from federal level to county health secretaries, including local non-governmental organisations. The availability of data, as well as the skilled use of spatial analysis tools, contributed in this process, allowing rapid and low cost assessments of environmental risks.

Light-driven molecular rotary motors are nanometric machines able to convert light into unidirectional motions. Several types of molecular motors have been developed to better respond to light stimuli, opening new avenues for developing smart materials ranging from nanomedicine to robotics. They have great importance in the scientific research across various disciplines, but a detailed comprehension of the underlying ultrafast photophysics immediately after photo-excitation, that is, Franck-Condon region characterization, is not fully achieved yet.

This paper introduces a novel energy-efficient lightweight, void hole avoidance, localization, and trust-based scheme, termed as Energy-Efficient and Trust-based Autonomous Underwater Vehicle (EETAUV) protocol designed for 6G-enabled underwater acoustic sensor networks (UASNs). The proposed scheme addresses key challenges in UASNs, such as energy consumption, network stability, and data security. It integrates a trust management framework that enhances communication security through node identification and verification mechanisms utilizing normal and phantom nodes.
