A clustering architecture that dynamically groups the search result documents into clusters labeled by phrases extracted from the search result snippets. Documents related to the same topic usually share a common vocabulary. The words are first clustered based on their co-occurrences and each cluster forms a potentially interesting topic. Keywords are chosen and then clustered by counting co-occurrences of pairs of keywords. Documents are assigned to relevant topics based on the feature vectors of the clusters.

Techniques for processing impedance data to provide an early warning for heart failure decompensation are described. An example device may be configured to measure intrathoracic impedance values, and increment an index when a determined impedance is less than a reference impedance. The incrementing may be based on the difference between the reference impedances and the determined impedance. In some examples, the amount of incrementing is reduced based on a variability of the impedances, or increased over time so long as the index remains above a threshold, e.g., zero. In some examples, the manner is which the reference impedances are determined changes over time to, for example, address rapid changes in impedance after device or system implantation. In some examples, the index is compared to a threshold to determine whether to provide an alert. In some examples, two thresholds are used to provide hysteresis.

An intranet mediator for obtaining direct answers to natural language questions allowing users to search both reconciled structured data repositories and unstructured data sources. The intranet mediator allows the user to obtain an answer to a natural language question without having to surf the data sources in which the answer might be contained, or without being limited to one specific factual item return. The intranet mediator operates on the supposition that most answers to business queries are contained within data sources that have been integrated into the reconciled structured data repository thereby having common schema and known contents. Preselection of the most relevant data source(s) is thus possible before query output. Searches of unstructured data can also be performed for additional context surrounding either the question or the answer. A direct answer is given in answer to the question. If desired, the intranet mediator may also display a list of data sources where additional relevant information may be found.

The invention also can be used for removing heavy metals such as copper, chromium, cadmium, lead and the like in water by sedimentation. The multiple-element compounded flocculating settling agent can be used together with a multiple-element compounded metal oxide arsenic removal setting agent in static or flowing arsenic pollution water body treatment for removing the arsenic in the water body polluted by arsenic.

A system and method for rapidly switching stimulation parameters of a Spinal Cord Stimulation (SCS) system increases the number of stimulation parameter sets that may be tested during a fitting procedure, or alternatively, reduces the time required for the fitting procedure. The switching method comprises selecting a new stimulation parameter set, and setting the initial stimulation levels to levels at or just below an estimated perception threshold of the patient. The estimated perception level is based on previous stimulation results. The stimulation level is then increased to determine a minimum stimulation level for effective stimulation, and/or an optimal stimulation level, and/or a maximum stimulation level, based on patient perception.
