摘要： This disclosure shows how a time series of measurements of an evolving system can be processed to create an “inner” time series that is unaffected by any instantaneous invertible, possibly nonlinear transformation of the measurements. An inner time series contains information that does not depend on the nature of the sensors, which the observer chose to monitor the system. Instead, it encodes information that is intrinsic to the evolution of the observed system. Because of its sensor-independence, an inner time series may produce fewer false negatives when it is used to detect events in the presence of sensor drift. Furthermore, if the observed physical system is comprised of non-interacting subsystems, its inner time series is separable; i.e., it consists of a collection of time series, each one being the inner time series of an isolated subsystem. Because of this property, an inner time series can be used to detect a specific behavior of one of the independent subsystems without using blind source separation to disentangle that subsystem from the others. The method is illustrated by applying it to: 1) an analytic example; 2) the audio waveform of one speaker; 3) mixtures of audio waveforms of two speakers.

摘要： Techniques are described to mitigate ad stalking and other user concerns resulting from user-targeted advertising. A user may be informed of advertising information by a process in which an advertising server receives a request for an ad. The request may have been generated in response to a user request for a landing web page. An ad may be selected based on user information available to the advertising server, where the user information is associated with the user and describes behavior and/or attributes and/or preferences associated with the user. Text about how the ad was selected may be incorporated into the ad. Such text may describe the user information used to select the ad. The selection-disclosing text may be incorporated in the ad in a form that is displayable to the user by a browser. The ad may then be transmitted for display in the landing web page.

摘要： A web services namespace pertains to an infrastructure for enabling creation of a wide variety of applications. The infrastructure provides a foundation for building message-based applications of various scale and complexity. The infrastructure or framework provides APIs for basic messaging, secure messaging, reliable messaging and transacted messaging. In some embodiments, the associated APIs are factored into a hierarchy of namespaces in a manner that balances utility, usability, extensibility and versionability.

摘要： Mechanisms in which upon receiving a message, the message is passed through one or more receiving path components that are positioned in the receiving path of the message prior to being passed to a dispatching component. One or more of the receiving path components may modify the message to include information that may be helpful to the dispatching component in order to perform the dispatch. The dispatching component receives modified message, and uses information from the modified message (including potentially the modification itself) to perform the dispatch. Since the message is modified to include additional information helpful to the dispatching component, the dispatching component may be more flexible in identifying the processing that should occur with the message. Accordingly, specialized and flexible processing may be enabled that is ideally suited for the message.

摘要： A method includes advertising a policy characterizing communication properties supported by a node. The policy may be distributed to another node in response to a request for the policy. Policy expressions in the policy include one or more assertions that may be grouped and related to each other in a plurality of ways. A system includes a policy generator for generating at least one policy characterizing properties of a node. A policy retriever retrieves a policy from another node and a message generator generates a message to the other node, wherein the message conforms to the policy from the other node.

摘要： A method includes retrieving an intermediate node policy characterizing communication properties supported by an intermediate node, the intermediate node being between a source node and a destination node in a communication path. The method includes forming a first policy-compliant message in accordance with the intermediate node policy, the first policy-compliant message including a request for a destination node policy characterizing communication properties supported by the destination node. A system includes a policy retriever comparing a source policy to one to an intermediate policy to determine whether the source policy is compatible with the intermediate policy. A message generator generates a policy request message by applying the intermediate policy to a request for a policy related to a destination node.

摘要： Implementations are described and claimed herein for content-based routing of messages in an overlay network. According to an exemplary implementation, routing nodes receive messages and return routing policies to the sending node based at least in part on content of the message. The routing policies include instructions for redirecting similar messages to other nodes in the overlay network. The sending node determines which policies to apply to the message. The sending node may then iterate through the routing policies, modifying the address in the message according to instructions included in the routing policies so that the message is sent, e.g., directly to the intended destination. Accordingly, the sending node is able to bypass one or more intermediary nodes to reduce latency in the overlay network.

摘要： A portable apparatus for detecting the presence of at least one methylxanthine chemical species such as caffeine or theophylline in a beverage comprises a first portion comprising an effective concentration of phosphodiesterase enzyme, a second portion comprising cyclic AMP, and means for indicating inhibition of degradation of the cyclic AMP by the phosphodiesterase due to the presence of the methylxanthine species. A method for determining the presence of at least one methylxanthine chemical species in a beverage comprises contacting at least one test portion of the beverage with effective concentrations of at least one phosphodiesterase enzyme and cyclic AMP, and further contacting the test portion with means for indicating the inhibition of the degradation of the cyclic AMP by the phosphodiesterase due to the presence of the methylxanthine species. The apparatus and method are advantageous in that they provide a simple and effective means of determining whether methylxanthine chemical species such as caffeine or theophylline are present in coffee, tea and other beverages.
