The global spread of COVID-19 has led to profound reflection on building a global public health security system.This paper uses the urban data collected during the COVID-19 epidemic in China in 2020 to evaluate the moondrop quarks effect of the National Sanitary City (NSC) policy on the prevention and control of that epidemic at different stages.We
Developmental and Post-Eruptive Defects in Molar Enamel of Free-Ranging Eastern Grey Kangaroos (Macropus giganteus) Exposed to High Environmental Levels of Fluoride.
Dental fluorosis has recently been diagnosed in wild marsupials inhabiting a high-fluoride area in tennessee titans dog bandana Victoria, Australia.Information on the histopathology of fluorotic marsupial enamel has thus far not been available.This study analyzed the developmental and post-eruptive defects in fluorotic molar enamel of eastern grey
A Radar Signal Recognition System Based on Non-Negative Matrix Factorization Network and Improved Artificial Bee Colony Algorithm
The development of cognitive radio and electronic warfare brings new challenges to radar electronic reconnaissance, the recognition of radar signal plays an extreme important role in radar electronic reconnaissance.In order to realize the reliable recognition of radar signal at the condition of low signal-to-noise Jeans ratio (SNR), we propose a ne
Collembola interact with mycorrhizal fungi in modifying oak morphology, C and N incorporation and transcriptomics
Soil detritivores such as Collembola impact plant growth, tissue nutrient concentration and gene expression.Using a model system with pedunculate oak (Quercus robur) microcuttings that display a typical endogenous rhythmic growth with read more alternating shoot (SF) and root flushes (RF), we investigated the transcriptomic response of oak with and
