Mobile App-Based Self-Management of Urinary Incontinence in Pregnant Women: Multicenter Pragmatic Randomized Controlled Trial.

Background: Urinary incontinence (UI) is a common condition during pregnancy, significantly impacting the physical and mental well-being as well as quality of life. With advancements in mobile health technology, mobile apps provide innovative approaches for managing UI. Although small-scale studies have demonstrated their efficacy in alleviating maternal UI symptoms, there is a notable lack of large-scale, multicenter trials to validate these findings.

Observing two-photon subwavelength interference of broadband chaotic light in a polarization-selective Michelson interferometer.

We demonstrated a method to achieve the two-photon subwavelength effect of true broadband chaotic light in polarization-selective Michelson interferometer based on two-photon absorption detection. To our knowledge, it is the first time that this effect has been observed with broadband chaotic light. In theory, the two-photon polarization coherence matrix and probability amplitudes matrix are combined to develop polarized two-photon interference terms, which explains the experimental results well.

Controllable superbunching effect from four-wave mixing process in atomic vapor.

Correlation property of light limits the performance in related applications such as the visibility of ghost imaging or intensity interferometry. To exceed these performance limits, we here manipulate the degree of second- and higher-order coherence of light by changing controllable variables in four-wave mixing (FWM) process. The measured degree of second- and third-order coherence of the output light beams considerably exceed those of the incident pseudothermal light.
