The detector array method has been widely used in the field of high-energy laser far-field spot parameter measurement due to its ability to directly measure the far-field spot of high-energy lasers, wide dynamic range of the detectors, high system sampling frequency, good real-time performance, and Dishwasher Airbreak Hose suitability for various t
The annual migration and spawning event of Pacific salmon (Oncorhynchus spp.) can lead to cross-boundary delivery of marine-derived nutrients from their carcasses into adjacent terrestrial ecosystems.The densities of some passerine species, including Pacific wrens (Troglodytes pacificus), have been shown to be positively correlated with salmon abun
Summary: Persistent viral infections subvert key elements of adaptive immunity.To compare germinal center (GC) B cell responses in chronic and acute lymphocytic choriomeningitis virus infection, we exploit activation-induced deaminase (AID) fate-reporter mice and perform adoptive B cell transfer experiments.Chronic infection yields GC B cell respon
In order to solve the problem of communication information blockade during disaster rescue in coal mines underground, a new type of mine-used digital broadcasting rescue guide system was developed.The key technologies, main devices and Changing Pad characteristics of the system were introduced.The system uses technologies of IP network communicatio
