The order of the plaintext remains in the ciphertext, so order-preserving encryption (OPE) scheme is under threat if the adversary is allowed to query for many times. To hide the order in the ciphertext, the only ideal-security OPE scheme (Popa et al., 2013) requires the database server to maintain extra information and realize comparison or range query by user defined functions (UDFs). However...

Order Preserving Encryption (OPE) schemes have been examined to a great extent in the cryptography literature because of their prospective application to database design. OPE is an appealing method for database encryption as it permits to execute sort and range queries in an efficient manner without decrypting the data. Databases such as CryptDB are beginning to employ encryption to guard sensi...

BACKGROUND Several studies have shown that outpatient preoperative evaluation by anaesthetists increases quality of care and is cost-effective. The aim of this study was to gain insight into the factors that positively or negatively influence the implementation of outpatient preoperative evaluation clinics (OPE clinics). METHODS After an extensive literature study and pilot interviews, we con...

The objective of this study was to evaluate the possibility of photoinduced stack/rod electron transfer in surface "zipper" architectures composed of stacks of blue (B) naphthalenediimides (NDIs) along strings of oligophenylethynyl (OPE) rods. The synthesis and characterization of anionic and cationic multichromophoric OPE-B systems are reported. Absorption spectra suggest that in OPE-B systems...

We show that the correlator of three large charge operators with minimal scaling dimension can be computed semiclassically in conformal field theories (CFTs) a $U(1)$ symmetry for arbitrary fixed values ratios their charges. obtain explicitly operator product expansion coefficient from numerical solution nonlinear boundary value problem superfluid effective theory $3d$. The result applies all t...

Onion peel contains a high concentration of quercetin and other flavonoids. In this study, the potential immune-enhancing effects of an onion peel water extract (OPE) supplement were investigated by the rat forced swimming test. OPE was prepared using hot water. Thirty-six male Sprague Dawley rats were fed a pellet diet for 1 week and were then randomly divided into six groups: normal control (...

We review the status of the practical operator product expansion (OPE), when applied to twopoint correlators of QCD currents which interpolate to mesonic resonances, in view of the violations of local quark-hadron duality. Covered topics are: a mini-review of mesonic QCD sum rules in vacuum, at finite temperature, or at finite baryon density, a comparison of model calculations of current-curren...

Quartz crystal microbalance (QCM) and surface plasmon resonance (SPR) were used to study zipper and layer-by-layer multilayer assemblies of artificial photosystems based on naphthalenediimides (NDIs) attached to an oligophenylethynyl (OPE-NDI) or p-oligophenyl (POP-NDI) backbone in dry and wet state. For the most interesting OPE-NDI zipper, one obtains for the dry film a monolayer thickness of ...
