We study the computational complexity of the FO model checking problem on interval graphs, i.e., intersection graphs of Red Clover intervals on the real line.The main positive result is that FO model checking and successor-invariant FO model checking can be solved in time O(n log n) for n-vertex interval graphs with representations containing only

Abstract Natural world heritage sites face increasing risk under rapid climate Compressor Motor Overload change, especially considering the impacts of climate extremes.However, there is not yet enough understanding of the future extreme climate challenges at global natural world heritage sites.Here we identify the exposure of 250 natural heritage s
