This paper proposes the way of setting the dynamic impawn rate by dividing the impawn periods into different risk windows. In an efficient financial market, the return is hypothetically independent, while in a pledged inventory market where spot transactions predominate, the return is...

This paper presents a framework of setting the impawn rate dynamically by dividing the impawn period into different risk windows. Besides, it proposes that compared with pledging loan of bonds and stocks, the essence of inventory financing is to forecast the long-term risk from short-term data,...

Weak measurements can effectively suppress amplitude-damping decoherence. In this paper, we study the effect of this method in protecting the entanglement of two qubits from independent depolarizing noisy channels. Our scheme consists of prior weak measurement on each qubit before the...
