The present disclosure provides a data mutex filter circuit and a data mutex filtering method. The data mutex filter circuit has a main input terminal and a main output terminal and including a preprocessing sub-circuit and a 1st-stage filter sub-circuit to an Nth-stage filter sub-circuit which are cascaded, N being an integer greater than or equal to 2. The 1st-stage filter sub-circuit has an input terminal coupled to the preprocessing sub-circuit, and the Nth-stage filter sub-circuit has an output terminal coupled to the main output terminal. Each stage of filter sub-circuit is configured to compare whether input data currently received at the main input terminal is the same as history data stored therein, and feed back a comparison result to the preprocessing sub-circuit; the preprocessing sub-circuit outputs corresponding data to the 1st-stage filter sub-circuit according to the comparison result fed back by each stage of filter sub-circuit.

In an example, a method for managing a virtual network is provided. According to the method, first and second domains are respectively created for heterogeneous first and second hypervisor mangers. The first hypervisor manager manages a first virtual machine (VM) and first virtual switch (vSwitch) The second hypervisor manager manages a second VM and a second vSwitch. Based on topology of the virtual network, topology management information may be created, which comprises first and second virtual network topology information respectively for the first and second domains, and first and second configuration information respectively for the first and second vSwitches. The topology management information may be distributed to the first and second hypervisor mangers after being associated with the first and second domains, so to the first and second vSwitches implement packet forwarding between the first and second VMs according to the first and second configuration information respectively.

Virtual network management

Using historical queries to determine database columns to populate a partial database. A partial database is created based, at least in part, on key values related to columns in a database for which the columns are most frequently accessed.

Disclosed is a stent with a drug coating for preventing and treating restenosis, comprising a stent and a drug coating covering the surface of the stent. The active ingredients in the drug coating are guaiane sesquiterpene compounds P1, P2 and P3. P1 is Zedoalactone B, P2 is a stereoisomer of P1, and P3 is Zedoarondiol. Compared with an existing sirolimus eluting stent, the present drug eluting stent can inhibit the intimal hyperplasia and the inflammatory reactions of vascular walls, and promote the endothelialization of blood vessels after the stent is implanted, and thus can prevent the long-term thrombotic complications; and has the advantages of small dosage, low cost, and no toxic side effect.

Scaffold with drug coating for treating restenosis and preparation method thereof

Processing a database table comprises receiving a multi-dimensional processing instruction for processing at least two columns of the database table, wherein the two columns comprise a selection column and a sort column, wherein the multi-dimensional processing instruction is for selecting a plurality of candidate rows by sorting based on the selection column and the sort column. An index takes the selection column as master column and the sort column as slave column. Nodes in the index are selected according to the selection column. Each of the selected nodes is associated with a respective slave column value sequence. A merge sort is performed on each of the slave column value sequences to obtain a sort result for the candidate rows.
