Recently, the power systems with a high penetration of renewables and power electronics have come into being.In these power systems, complex system dynamics, emergency faults, and insufficient frequency regulation reserve pose threats to system frequency stability.Based on the clustering development of energy storage, to ensure the system frequency
Less invasive surfactant administration versus intubation-surfactant-extubation in preterm infants: a retrospective study
Aim To compare the need for intubation and mechanical ventilation after surfactant delivery between less invasive surfactant administration (LISA)-treated and intuba-tion-surfactant-extubation (IN-SURE)-treated premature infants with respiratory distress syndrome (RDS). Methods Retrospective registry-based cohort study enrolled 36 newborns adm
Repeated Reticulate Evolution in North American Papilio machaon Group Swallowtail Butterflies.
Hybridization between distinct populations or species is increasingly recognized as an important process for generating biodiversity.However, the interaction between hybridization and speciation is complex, and the diverse evolutionary outcomes of hybridization are difficult to differentiate.Here we characterize potential hybridization in a species
Assessment of the feed additive consisting of Pediococcus pentosaceus DSM 14021 for all animal species for the renewal of its authorisation (Chr. Hansen A/S)
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the assessment of the application for renewal of Pediococcus pentosaceus DSM 14021, a technological additive for all animal species.The applicant has provided evidence that the additive currently on the market complies with the existing cond
