BDD-Net: A General Protocol for Mapping Buildings Damaged by a Wide Range of Disasters Based on Satellite Imagery

The timely and accurate recognition of damage to buildings after destructive disasters is one of the most important post-event responses.Due to the complex and dangerous situations in affected areas, field surveys of post-disaster conditions are not always feasible.The use of satellite imagery for disaster assessment can overcome this problem.Howev

Positivity bounds on Higgs-Portal dark matter

Abstract We consider the positivity bounds for WIMP scalar dark matter with effective Higgs-portal couplings up to dimension-8 operators.Taking the superposed states for Standard Model Higgs and scalar dark matter, we show that the part of the parameter space for the effective couplings, otherwise unconstrained by phenomenological bounds, is ruled
