Abstract: A method for authenticating a transaction includes: receiving, responsive to an occurrence of an event suspected to compromise a first security value associated with a transaction card, personal identification information associated with a user of the transaction card; authenticating, via a transaction device and using the personal identification information, the user as being associated with the transaction card; responsive to authenticating the user, replacing, using the transaction device, the first security value associated with the transaction card with a second security value associated with the transaction card; authenticating the transaction based at least in part on a comparison between a stored security value and the second security value associated with the transaction card; and in response to a successful authentication of the transaction, processing the transaction.

Abstract: Methods of treating drilled or fractured subterranean formations include the steps of packing at least a portion of the subterranean formation with a packing composition to form a packed subterranean formation; and applying a sealing composition to the packed subterranean formation to form a treated subterranean formation. Alternatively, a packing composition is mixed with a sealing composition to form a reactive composition, and the reactive composition is applied to at least a portion of the subterranean formation to form a treated subterranean formation. The reactive compositions cure within the treated subterranean formations to provide sealed subterranean formations.

Abstract: A method for authenticating a transaction includes replacing a first security value of a transaction device with a second security value; receiving, during a first transaction, the second security value; authenticating the first transaction based at least in part on the second security value; determining that a predetermined number of transactions have occurred during which the second verification value was not rewritten since the second security value was replaced; responsive to determining that the predetermined number of transactions have occurred, replacing the second security value on the transaction device with a third security value; receiving, during a second transaction, the third security value; and authenticating the second transaction based at least in part on the third security value.

Abstract: A model-assisted system and method for predicting health care services. In one implementation, a model-assisted system may comprise a least one processor programmed to access a database storing a medical record associated with a patient and analyze the medical record to identify a characteristic of the patient. The processor may determine a patient risk level indicating a likelihood that the patient will require a health care service within a predetermined time period; compare the patient risk level to a predetermined risk threshold; and generate a report indicating a recommended intervention for the patient. The processor may further determine a calibration factor indicating a difference between an average patient risk level and an average actual healthcare service usage for a first group of patients; and determine, based on the calibration factor, a bias relative to a second group of patients.

Abstract: A computer-implemented method for facilitating an emergency relief donation includes receiving, by a financial institution computer system, a donation pledge from a donor to send funds to a donee from a payment account of the donor, wherein the donation pledge includes payment account information, receiving, by the financial institution computer system, a request for the funds from the donee via a banking device provided by the financial institution computer system, wherein the request includes donee identification information, verifying, by the financial institution computer system, the identity of the donee based on the donee identification information, and transferring, by the financial institution computer system, the funds from the payment account of the donor to the donee via the banking device and based on the payment account information.

Abstract: Embodiments of the method for authenticating may include causing an automated teller machine to replace a card verification value with an updated card verification value during a first transaction at the automated teller machine when a re-write condition is present, such as a request from an account holder, a determination that the security of the card was compromised during a prior transaction, a predetermined time interval has lapsed, a predetermined number of transactions have occurred since a previous time the card verification value was rewritten, and according to a predetermined geographical parameter. The updated card verification value may be stored as a current value in a verification value database. The method may include receiving a card verification request related to a second transaction, and authenticating, using verification logic, the second transaction by determining whether the card verification value for the second transaction matches the current value stored in the database.

Abstract: A method may include preparing a map of cement quality for one or more intervals of a wellbore; determining anticipated regions of fluid communication and anticipated regions of zonal isolation from the map of cement quality; and designing a stimulating treatment based on the presence of regions of fluid communication.

Abstract: A wrist band having a flexible band portion with inward and outward sides, a cover of an absorbent material, and a badge. A first band end portion has a first band end wall and a second band end portion has a second band end wall. The band end walls positioned adjacent to each other and may be joined together. The badge has an inward badge portion attached to inward sides of the band end portions and an outward badge portion attached to outward band sides of the band end portions. The outward badge portion has an outward facing display surface.

Abstract: Methods of treating formation damage or other service induced damage in a near wellbore region of a wellbore of a subterranean formation, by treating a zone or zones in the near wellbore region, and diverting treatment fluid stages from the treated zones to untreated zone(s) with an acid precursor material and optionally also with fibers. The acid precursor material has an average particle size less than 1000 microns.

Abstract: Systems and methods for handling wellsite packets for a wellsite are provided. The wellsite packets include soluble packaging with wellsite materials therein. The wellsite has surface equipment and downhole equipment positioned about a wellbore. The handling system includes at least one feeder, at least one mixer, at least one metering device, and a pump. The feeder moves the wellsite packets directly or indirectly into the mixer. The mixer stimulates dissolution of the soluble packaging so as to mix the wellsite materials with a fluid to form a wellsite mixture. The metering device selectively controls the number of wellsite packets moving to the mixer. The pump is operatively coupled to the mixer to pump the wellsite mixture at the wellsite.
