A security monitoring system processes event messages related to computer network security in real time, evaluating inter-event constraints so as to identify combinations of events that are partial solutions to a predefined event correlation rule, and furthermore evaluating combinations of the partial solutions do determine if they together satisfy the predefined event correlation rule. A decision tree is formed based on the rule. Event messages are categorized into groups at leaf nodes of the tree in accordance with a plurality of intra-event constraints, and then the messages are correlated in accordance with a plurality of inter-event constraints at non-leaf nodes of the tree. When the inter-event constraint at a root node of the tree has been satisfied, a network attack alert is issued and protective actions may be taken.

An MAS probe is disclosed for obtaining a substantial improvement in signal to noise (S / N) in triple-resonance high-resolution (HR) magic-angle-spinning (MAS) NMR of samples near room temperature (RT) in high-field magnets where the magnet's RT shim bore is greater than 60 mm. All critical circuit components, including the sample coils, are located along with the spinner assembly in a thermally insulated cold zone pressurized with helium gas. The spinner assembly attaches to a sealed, curved, rotor-loading tube to permit automatic sample change, and it is surrounded by a partially insulated jacket cooled with a cryogenic fluid, generally nitrogen gas. The MAS probe is also compatible with magic angle gradients, variable temperature operation, field locking, and commonly available closed-cycle cold fingers. One major challenge in implementing CryoMAS is solving the problem of gas leakage from the spinner bearing, drive, and exhaust nitrogen into the cold zone, as some components will necessarily be ceramic, some plastic, and some metal. It is not desirable to use helium for the spinner bearing and drive gases for cost reasons and to prevent risk of degradation of o-ring-sealed magnet cryostats. A pressurized helium atmosphere in the cold zone may be utilized to prevent nitrogen flow from the spinner exhaust streams or atmosphere into the cold zone. The drawback to a pressurized cold zone is that the heat transfer coefficient in dense helium at low temperatures is very high, making it challenging to cool the sample coils and all the large, critical, circuit components in a practical manner. Part of the solution here is to use a first-stage cooling-jacket around the major heat leaks near the spinner exhaust flows. The critical components may be insulated with fine glass wool or teflon foam and conduction cooled without cooling much of the cold zone below the temperature of the first-stage cooling. The use of coaxial sapphire capacitors allows the noise contributions from the most critical capacitors to be reduced to a minor fraction of the total.

A method of determining buffer insertion locations in an integrated circuit design establishes candidate locations for inserting buffers into a net, and selects buffer insertion locations from among the candidates based on slew constraints. The selection of buffer insertion locations preferably optimizes slack and buffer cost while keeping slew from any buffered node to any sink less than a required slew rate. The slew analysis computes an output slew SL(v) of a given buffer b inserted at a node v as SL(v)=RS(b)·C(v)+KS(b), where C(v) is the downstream capacitance at v, RS(b) is the slew resistance of buffer b, and KS(b) is the intrinsic slew of buffer b. The delay through a given buffer may also be computed based on signal polarity. However, the invention still preferably uses worst-case slew resistance and intrinsic slew in considering the slew constraints. If the selection of the buffer insertion locations results in no locations being selected due to slew violations, the present invention may advantageously find a partial solution by relaxing the slew constraint.
