A New Design Method of Shield Tunnel Based on the Concept of Minimum Bending Moment
As the soil-resistance coefficient in a soft soil area is small, overlarge bending moment may cause exceeding transverse deformation for the shield tunnel and cause structural diseases and waterproof failure at the longitudinal segment joints.

Comparison of Indoor Radon Reduction Effects Based on Apartment Housing Ventilation Methods
A lack of ventilation in multi-unit dwellings can affect human health adversely owing to accumulated radon gases; therefore, developing immediate and effective methods to reduce radon gas in indoor living environments is urgently needed.

Noise expresses exponential growth under regime switching [PDF]
Consider a given system under regime switching whose solution grows at most polynomially, and suppose that the system is subject to environmental noise in some regimes. Can the regime switching and the environmental noise work together to make the system
