The paper addresses two problems belonging to the basic combinatorics of words. They are connected with the operations of sequential insertion and deletion, which are nondeterministic versions of catenation and right/ left quotient. Necessary and sufficient conditions, under which the result of sequential insertion or deletion of two words is a singleton set, are given. Also the situation when ...

The aim of this paper is to propose some diagnostic methods in linear ridge measurement error models with stochastic linear restrictions using the corrected likelihood. Based on the bias-corrected estimation of model parameters, diagnostic measures are developed to identify outlying and influential observations. In addition, we derive the corrected score test statistic for outliers detection ba...

Broadbent and Islam (TCC '20) proposed a quantum cryptographic primitive called encryption with certified deletion. In this primitive, receiver in possession of ciphertext can generate classical certificate that the encrypted message is deleted. Although their construction information-theoretically secure, it limited to setting one-time symmetric key (SKE), where sender have share common advanc...

There is always a trade off between the number of cases to be stored in the case library of a Case-Based Expert System and the performance of retrieval efficiency. The larger the case library, the more the problem space covered, however, it would also downgrade the system performance if the number of cases grows to an unacceptable high level. In this paper, an approach of maintaining the size o...
