Full Event Particle-Level Unfolding with Variable-Length Latent Variational Diffusion

SciPost Physics
The measurements performed by particle physics experiments must account for the imperfect response of the detectors used to observe the interactions. One approach, unfolding, statistically adjusts the experimental data for detector effects.

Physical characterization of aerosol particles during the Chinese New Year’s firework events

Atmospheric Environment, 2010
Abstract Measurements for particles 10 nm to 10 μm were taken using a Wide-range Particle Spectrometer during the Chinese New Year (CNY) celebrations in 2009 in Shanghai, China. These celebrations provided an opportunity to study the number concentration and size distribution of particles in an especial atmospheric pollution situation due to firework
