A database structure of a sort defined by an access and query language that defines tables of variables having labels and field characteristics, such as ANSI structured query language (SQL), is modified by determining the structural differences between an existing schema and a new schema, independent of database contents. The differences are processed to generate commands that are then applied to evolve an existing database from the old schema or structure to the new one. This avoids the need to dump and restructure the contents of the old database for reload into an empty new database that has been prepared to meet the new schema.

A technique for interference suppression in MC-CDMA systems is proposed which exploits the structural differences in signals that arrive at the receiver with Doppler shifts or carrier offsets. Oversampling the received signal in the frequency domain and properly combining the samples provides the interference suppression. Frequency domain oversampling is accomplished by using a time extension of the conventional MC-CDMA signal. Furthermore, a receiver structure is introduced that despreads and combines groups of samples so that a linear minimum mean-squared error solution for combining the groups is easily found. This combining scheme increases the signal-to-interference ratio (SIR) experienced by the desired user in the MC-CDMA system. In addition, the receiver performs well in severe near-far scenarios when there is sufficient Doppler separation between the signals of the desired user and an interferer. Numerical results show that the proposed receiver significantly outperforms the conventional MC-CDMA receiver.

The invention discloses a sodium nitroprusside-conjugated medicine-carrying prussian blue analogue nano-photothermal therapeutic agent and a preparation method thereof. The particle size of the sodiumnitroprusside-conjugated medicine-carrying prussian blue analogue nano-photothermal therapeutic agent prepared by a hydrothermal reaction method is 205.4nm, and passive targeting can be achieved by means of an enhanced permeability and retention (EPR) effect of a tumor site. Under the illumination of near-infrared laser, the nano-photothermal therapeutic agent can not only induce photothermal ablation of tumor cells through excellent photothermal conversion efficiency, but also can control NO release, thereby improving the EPR effect and increasing intratumoral delivery of nanoparticles. Furthermore, the NO can also inhibit tumor progression by inducing apoptosis of the tumor cells, preventing angiogenesis, reversing multidrug resistance, and the like. On the other hand, due to the structural difference between sodium nitroprusside and potassium ferricyanide, the lattice defects of the nanoparticles are caused, and the drug loading capacity of the nano-photothermal therapeutic agent is accordingly increased. Therefore, after chemotherapeutic drugs are carried, under the irradiation of near-infrared light, the nano-photothermal therapeutic agent can realize dose-controlled NO release and phototherapy and chemotherapy combined oncotherapy. In addition, the sodium nitroprusside-conjugated medicine-carrying prussian blue analogue nano-photothermal therapeutic agent provided by theinvention also has good photothermal stability and certain photoacoustic contrast properties.
