Respiro is a medical device startup based in Dubai, United Arab Emirates, founded in late 2025. The company is developing a wearable respiratory monitor designed to predict asthma attacks before patients experience symptoms, through continuous acoustic monitoring of lung sounds. As of early 2026, the company has no commercial product and remains in the research and development phase.

The Sack–Schamel equation describes the nonlinear evolution of the cold ion fluid in a two-component plasma under the influence of a self-organized electric field. It is a partial differential equation of second order in time and space formulated in Lagrangian coordinates. The dynamics described by the equation take place on an ionic time scale, which allows electrons to be treated as if they were in equilibrium and described by an isothermal Boltzmann distribution. Supplemented by suitable boundary conditions, it describes the entire configuration space of possible events the ion fluid is capable of, both globally and locally.
