A reliability study was conducted to estimate uncertainty in seismic response analysis. The study deals with evaluation of structures subjected to short-duration dynamic and seismic loading. A finite element method (FEM)-based formulation was used in the study to model complex mechanical behaviours. A nonlinear FEM-based algorithm incorporating uncertainties in the random variables, including seismic loading, is proposed in the study to estimate the reliability of realistic structural systems. The nonlinear finite element-based hybrid method, proposed in the model will help to track the propagation of uncertainties in the seismic response analysis.

In this paper the authors present the results of a prototype implemented based on previous concept studies: a novel mobility management framework with functions for built-in verification of configuration changes and for fault tolerance. This mechanism is required for increased network stability, to prevent the data loss, inadequate changes and to ensure that the moving user stays connected even in a busy network environment. The scope of this paper is to propose a proof of concept study in order to demonstrate the reliability and the superiority of the new architecture when compared to the traditional peer-to-peer (P2P) model. The paper deals with the implementation of the algorithm for fault tolerance and functions for updating the network configuration against all unexpected changes. The advantage of this approach is that the fault rate is extremely decreased, the data flow is constant, time is saved, the client's performance is increased and the server load is reduced. The mobility framework is implemented in Java using OMNET++ platform as a simulation environment.

Surface ozone (O 3 ) pollution showed a continuous increasing trend during the recent decades in China, posing an increasing threat to food security. A wide range of yield reductions have been reported and thus more studies are needed to narrow down the uncertainty resulting from spatiotemporal accuracy of O 3 metrics and extrapolation methods. Based on a high spatial resolution (0.1°) hourly surface O 3 data, here we analyzed the spatiotemporal O 3 pollution patterns and impacts on yield, production and economic losses for wheat, rice, and maize in China during 2005–2020. The accumulated O 3 exposure over a threshold of 40 ppb (AOT40) increased by 10 % during 2005–2019, and a decrease of 5.56 % was observed in 2020 due to the COVID-19 lockdowns. Rising O 3 pollution reduced national level wheat, rice and maize yields by 14.51 % ± 0.43 %, 11.10 % ± 0.6 %, and 3.99 % ± 0.11 %, respectively. A Business-As-Usual projection suggested that the relative yield loss (RYL) would potentially reach 8 %–18 % at the national scale by 2050 if no emission control is implemented. COVID-19 lockdowns in 2020 led to significantly reduced RYL for maize (0.52 %) and rice (2.17 %) but not for wheat (0.11 %), with the largest reduction (1.88 %–9.4 %) in North China Plain, highlighting the potential benefits of emission control. Our findings provided robust evidence that rising O 3 pollution has significantly affected China's crop yields, production and economic losses, underscoring the urgent need to curb O 3 pollution to safeguard food security, particularly in densely populated and industrialized regions.
