Aquatic ecosystems house a significant fraction of Earth's biosphere, yet most prokaryotes inhabiting these environments remain uncultivated. While recently developed genome-resolved metagenomics and single-cell genomics techniques have underscored the immense genetic breadth and metabolic potential residing in uncultivated Bacteria and Archaea, cultivation of these microorganisms is required to study their physiology via genetic systems, confirm predicted biochemical pathways, exploit biotechnological potential, and accurately appraise nutrient turnover. Over the past two decades, the limitations of culture-independent investigations highlighted the importance of cultivation in bridging this vast knowledge gap.

This paper presents a comprehensive dataset of substation traffic, aimed at improving the training and benchmarking of Intrusion Detection Systems (IDS) installed in these facilities that are based on machine learning techniques. The dataset includes raw network captures and flows from real substations, filtered and anonymized to ensure privacy.

Methods: Descriptive study of the procedures implemented to achieve reverification of measles elimination by 2023 according to the components set forth in the Regional Framework for the Monitoring and Re-verification of Measles, Rubella, and Congenital Rubella Syndrome Elimination in the Americas, published in 2022.
Results: Due to a measles outbreak that began in epidemiological week (EW) 26 of 2017, Venezuela lost the elimination status which had been conferred in 2016 by the Expert Committee.
Objective: Describe the challenges, strategies and lessons learned in Venezuela during the measles outbreak of 2017-2019, and discuss the mechanisms employed for its containment, which led to the interruption of endemic transmission.
Methods: Descriptive study of the actions taken by Venezuela to interrupt the outbreak.
Results: When the outbreak was confirmed, the Venezuelan government, with technical cooperation from the Pan American Health Organization, activated a plan to interrupt measles transmission.
The development of superhydrophobic, waterproof, and breathable membranes, as well as icephobic surfaces, has attracted growing interest. Fluorinated polymers like PTFE or PVDF are highly effective, and previous research by the authors has shown that combining these polymers with electrospinning-induced roughness enhances their hydro- and ice-phobicity. The infusion of these electrospun mats with lubricant oil further improves their icephobic properties, achieving a slippery liquid-infused porous surface (SLIPS).
