A system and method for governing the sending and receiving of electronic mail, especially unsolicited bulk mail, spam, and mail viruses is described. A data token called an eMstamp, having a monetary value related to a number of imbedded eMstamp credits, is made a part of an outgoing electronic mail message transaction by the outgoing mail server. A mail server receiving mail examines the data of a message related eMstamp and makes rule based decisions to deliver or reject a mail message to the intended recipient mailbox based on the eMstamp data. Mail servers retain counts of incoming and outgoing eMstamp credits and use incoming eMstamp credits to offset credits needed to send mail. Administrators of mail servers having a greater number of outgoing eMstamp credits over incoming credits, will need to purchase eMstamp credits from an issuing agent to facilitate message delivery to other eMstamp enabled mail servers. Administrators of mail servers having a greater number of incoming eMstamp credits over outgoing credits can periodically redeem the excess of eMstamp credits for a monetary amount related to the purchase cost of credits. An intended consequence of the invention is to transfer revenue derived from the sale of eMstamp credits to eMstamp mail servers receiving more mail than is sent and to discourage the indiscriminate sending of electronic mail and self replicating e-mail viruses.

A method, computer program product, and system are provided to calibrate a sensor array with a plurality of sensors. The method can include sweeping a voltage of a reference electrode from a first voltage to a second voltage, where the reference electrode is in fluid communication with the sensor array. The output voltage of each of the plurality of sensors can be monitored at one or more voltages within the first and second voltages. An overall average gain of the plurality of sensors can be calculated at each of the one or more voltages. Further, an acquisition window for the sensor may can be determined. The acquisition window can include a maximum distribution of sensors that provides a maximal overall average gain at a particular reference electrode voltage.

A method for nucleic acid sequencing includes receiving a plurality of signals indicative of a parameter measured for a plurality of defined spaces, at least some of the defined spaces including one or more sample nucleic acids, the signals being responsive to a plurality of nucleotide flows introducing nucleotides to the defined spaces; determining, for at least some of the defined spaces, whether the defined space includes a sample nucleic acid; processing, for at least some of the defined spaces determined to include a sample nucleic acid, the received signals to improve a quality of the received signals; and predicting a plurality of nucleotide sequences corresponding to respective sample nucleic acids for the defined spaces based on the processed signals and the nucleotide flows.
摘要:
A method of obtaining a more accurate estimate of a signal correction parameter(s) in sequencing-by-synthesis operations, such as incomplete extension rates, carry forward rates, and/or signal droop rates. The sequencing operation produces signal data. A model is constructed to simulate a population of template strands as it undergoes the sequencing process and becomes divided into different phase-states as the sequencing-by-synthesis progresses. For example, the model may be a phase-state model. The output from the model is used to adjust the signal correction parameter(s). For example, the model may be fitted to the signal data. This fitting results in a more accurate estimate of the signal correction parameter(s). In another embodiment, the signal droop rate is modeled as a decaying function and this decaying function is fitted to the signal data to obtain an improved estimate of the signal droop rate.

A system including a communication interface to communicatively couple to a sensor cartridge, a fluidic subsystem to exchange a reagent solution with the sensor cartridge, and a computational circuitry communicatively coupled to the communication interface and the fluidic subsystem. The computation circuitry is to monitor a sensor signal of a sensor of the sensor cartridge, detect a leak based on the sensor signal, and control fluid flow of the fluidic subsystem in response to detecting.
