Based on the identification and analysis of safety risks in TBM tunnel construction, we construct a comprehensive safety risk dynamic evaluation index system tailored to this context. To account for the dynamic nature of safety risks during TBM tunnel construction, variable weight theory is incorporated, allowing for a more accurate reflection of the time-varying importance of risk indicators. Building on the theoretical framework of attribute interval recognition theory, we establish a TBM tunnel construction safety risk evaluation model grounded in attribute interval theory. This model effectively addresses the various uncertainties inherent in the risk evaluation process for TBM tunnel construction. It determines the evaluation level and attribute intervals for each individual indicator, and subsequently calculates the interval values for both the individual indicators and the composite attribute. Finally, a case study demonstrates the model’s effectiveness and practical applicability.

High sensitivity terahertz sensor based on semiconductor material for biosensing detection We propose a tri-band metamaterial sensor operating in the terahertz range, structured with a semiconductor-dielectric-semiconductor configuration. Tri-band resonance is produced by this structure at 4.216 THz, 5.210 THz, and 5.770 THz.The physical mechanism underlying these absorption peaks is elucidated through impedance matching theory.

1. IntroductionAircraft icing results in a decrease in aerodynamic performance, characterized by a reduction in lift, an increase in drag, a decrease in the stall angle, and an increase in aerodynamic nonlinearity under the same flight conditions [1,2,3]. Changes in the aircraft’s aerodynamic characteristics cause deviations from the original flight control design point, leading to a decline in maneuverability and stability, which significantly affects flight safety.

AbstractPhoto-oxidation of methane (CH4) using hydrogen peroxide (H2O2) synthesized in situ from air and water under sunlight offers an attractive route for producing green methanol while storing intermittent solar energy. However, in commonly used aqueous-phase systems, photocatalysis efficiency is severely limited due to the ultralow availability of CH4 gas and H2O2 intermediate at the flooded interface.
