The present disclosure also provides methods of detecting the presence of and/or the amount of at least one fungal plant pathogen in a sample, methods of making the biosensor described herein, as well as methods and uses of using the herein described biosensor for detecting the presence of and/or amount of at least one fungal plant pathogen.

Abstract: A computing system for remotely activating a transaction device including at least one memory having instructions stored thereon that, when executed by the at least one processor, cause the at least one processor to receive, from a mobile device, a transaction device identifier, receive, from the transaction device, an authorization request associated with a payment account for a transaction at the transaction device, receive location information from the mobile device and location information from the transaction device in response to receiving the authorization request, compare the location information to determine whether the mobile device is in proximity to the transaction device, and upon determining that the mobile device is in proximity to the transaction device, determine an authorization status of the authorization request, and transmit a signal to activate the transaction device to complete the transaction, wherein the signal is transmitted based on the transaction device identifier.

Abstract: A method of remotely activating a transaction device includes receiving, at a computing system, a mobile device identifier from a mobile application executed on a mobile device. A selection of the transaction device is received from the application. The selection includes an identifier of the transaction device. A selection of a transaction amount related to purchase of a product is received from the application. An authorization request for a payment account associated with the mobile device is communicated to an issuer of the payment account. The authorization request is for a transaction of at least the transaction amount. An authorization approval for the transaction is received from the issuer and a signal to activate the transaction device to dispense the product is sent based on the identifier. The transaction device is deactivated upon dispensing the transaction amount and a receipt of the transaction is provided to the mobile device.

Abstract: An impedance based biosensor and method for detecting a target biomolecule in a sample are provided. The biosensor has a substrate, and first and second spaced-apart electrodes disposed at the substrate. A molecular recognition element (MRE) for binding with the target is bound to the substrate between the first and second electrodes. The biosensor also has a nanoparticle having an MRE bound to its surface. In the presence of the target, the nanoparticle is immobilized between the first and second electrodes due to binding of the target biomolecule with the first MRE and binding of the target biomolecule with the second MRE. A measurable change in electrical impedance across the first and second electrodes occurs due to the immobilization of the nanoparticle between the first and second electrodes.

Abstract: This invention removes the effects of variable water velocity by calculating and applying corrections that map the seismic data to an ideal case of constant water velocity. All of the corrections assume, from a separate analysis step, that the vertical (zero-offset) timing errors induced by the water-velocity variations and that the zero-offset water bottom times are available. Equivalently, the water velocities are assumed known. The timing errors and water velocities are related. The zero-offset water-bottom times are also assumed available. From this information, and an arbitrarily-defined “ideal” water velocity, it is possible to calculate an observed (actual) water velocity relative to the “ideal” case. The only additional information needed is the angle of the ray path through the water layer. The angle may be calculated directly from normal moveout velocities derived from conventional analysis of the seismic data, and the information above.

Abstract: A system and method for the quantitation of whole body distribution of radiopharmaceuticals which can determine the percentage uptake of the radiopharmaceutical in a selected region of the body. The system obtains anterior and posterior views of the body using a scintillation camera. These views are then lined up and the geometric mean of the activity at each pixel location is determined. This normalizes the data to produce an activity level which would result if the organ studied were at midpoint of the body. As a result, fast and accurate results are obtained even for organs that are well visualized in only one of the anterior or posterior views.
