In this section the key methodological elements used to analyze the DAS data containing the May 17 parade are described. First, vertical forcing of pedestrians is analyzed via the frequency characteristics in the DAS data. Then, the walking pace…

Sample deposition and characterization

An approximately 45 nm thick thin film of VO₂ was deposited onto a 001 (c-cut) sapphire substrate using pulsed laser deposition at room temperature and subsequent annealing³⁷. The mean-square strain was…

The condition of ice in sporting arenas is a critical factor influencing the performance and safety of athletes, particularly in ice-dependent sports such as hockey, curling and figure skating. The way skates slide on ice is influenced by several…

Atom-based polarization holography

Schematic diagram of APH is depicted in Fig. 1a. Two 509-nm coherent laser beams, marked as R₁ and R₂, are employed as recording light. The polarization states of R₁ and R₂ are controlled separately with…

The term Ghost Imaging embeds the notion that images can be formed by photons that have not interacted directly with an object. The first demonstration of ghost imaging turns 30, and the rich physics contained therein remains inspiring, fuelling…
