Effects of Scalable, Wordless, Short, Animated Storytelling Videos on Flu Vaccine Hesitancy in China: Nationwide, Single-Blind, Parallel-Group, Randomized Controlled Trial.

Background: Low influenza vaccination rates in China pose a serious public health threat. The vaccination prevents infection, but widespread vaccine hesitancy remains a significant barrier. Short, animated storytelling videos may help by conveying health messages in an engaging, culturally neutral format that transcends literacy barriers.

375-395 nm UV generation in Zn-indiffused MgO-doped PPLN waveguides pumped by an Alexandrite laser.

We present results of wide wavelength coverage in the ultra-violet (UV) from a Zn-indiffused MgO-doped periodically-poled lithium-niobate (PPLN) waveguide. A continuous tuning range of 375-395 nm is obtained via second-harmonic-generation (SHG) in Λ = 6.1 - 6.

Direct identification of Ac and No molecules with an atom-at-a-time technique.

The periodic table provides an intuitive framework for understanding chemical properties. However, its traditional patterns may break down for the heaviest elements occupying the bottom of the chart. The large nuclei of actinides (Z > 88) and superheavy elements (Z ≥ 104) give rise to relativistic effects that are expected to substantially alter their chemical behaviours, potentially indicating that we have reached the end of a predictive periodic table.
