Query: Carleman and observability estimates for stochastic beam equation   In this paper, we establish a weight identity for stochastic beam equation by
means of the multiplier method. Based on this identity, we first establish the
global Carleman estimate for the special system with zero initial value and end
value, then a revised Carleman estimate for stochastic beam equation is
established through a cutoff technique. Finally, we use the revised Carleman
estimate to get the required boundary observability estimate.
