Order preserving encryption (OPE) is a kind of encryption designed to support searches on ciphertexts. OPE encrypts plaintexts to ciphertexts with the same order, making it possible to efficiently compare ciphertexts without decryption. Because of its efficiency, OPE has been used in systems aimed at practical use. However, even though many OPE schemes have been proposed, all suffer from securi...

BACKGROUND Quercetin derivatives in onions have been regarded as the most important flavonoids to improve diabetic status in cells and animal models. The present study was aimed to examine the hypoglycemic and insulin-sensitizing capacity of onion peel extract (OPE) containing high quercetin in high fat diet/streptozotocin-induced diabetic rats and to elucidate the mechanism of its insulin-sens...

Order-preserving encryption (OPE) and order-revealing encryption (ORE) are among the core ingredients for encrypted database (EDB) systems as secure cloud storage. In this work, we study the leakage of OPE and ORE and their forward security. We propose generic yet powerful file-injection attacks (FIAs) on OPE/ORE, aimed at the situations of possessing order by and range queries. The FIA schemes...

We initiate the cryptographic study of order-preserving symmetric encryption (OPE), a primitive suggested in the database community by Agrawal et al. (SIGMOD ’04) for allowing efficient range queries on encrypted data. Interestingly, we first show that a straightforward relaxation of standard security notions for encryption such as indistinguishability against chosen-plaintext attack (IND-CPA) ...

We discuss the operator product expansion (OPE) in the models with the SL2 affine symmetry. For this purpose, we calculate the correlation functions of the primary fields with definite SL2 weights. By using them and extending the arguments in the literature, we show that the OPE with one primary field in a degenerate representation is correctly obtained. We also study the OPE among the primary ...

We calculate the coefficients of the operator product expansion (OPE), in Polyakov’s approach for Burgers turbulence. We show that the OPE has to be generelized and it is shown that the extra term gives us the instanton solution (shock solution) of Burgers equation. We consider the effect of the new-term in the OPE, on the right and lefttail of probability distribution function (PDF). It is sho...

We take an analytic approach to the CFT bootstrap, studying the 4-pt correlators of d > 2 dimensional CFTs in an Eikonal-type limit, where the conformal cross ratios satisfy |u| |v| < 1. We prove that every CFT with a scalar operator φ must contain infinite sequences of operators Oτ,` with twist approaching τ → 2∆φ + 2n for each integer n as `→∞. We show how the rate of approach is controlled b...

The ubiquitous presence of nonylphenolethoxylate/octylphenolethoxylate (NPE/OPE) compounds in aquatic environments adjacent to wastewater treatment plants (WWTP) warrants an assessment of the endocrine disrupting potential of these complex mixtures on aquatic vertebrates. In this study, fathead minnow larvae were exposed for 64 days to a mixture of NPE/OPE, which closely models the NPE/OPE comp...
