Abstract: A method and federated publish/subscribe system for data transfer in the federated publish/subscribe system. The federated publish/subscribe system includes a processor, a first message broker, and a second message broker. The second message broker transmits, via the processor, a message A to a first subscribing application and a message (A+?) to a second subscribing application. The message (A+?) differs from the message A by changes ?. The first subscribing application and the second subscribing application are different subscribing applications. Prior to the transmitting by the second message broker, the second message broker receives, from the first message broker via the processor, either (i) a message (A, ?) comprising the message A and the changes ? or (ii) the message A and a message ? comprising the changes ?.

Abstract: In an example, the present invention provides a method of separating a photovoltaic strip from a solar cell. The method includes providing a solar cell, placing the front side of the solar cell on a platen such that the backside is facing a laser source, initiating a laser source to output a laser beam having a wavelength from 200 to 600 nanometers and a spot size of 18 to 30 microns, subjecting a portion of the backside to the laser beam at a power level ranging from about 20 Watts to about 35 Watts to cause an ablation to form a scribe region having a depth, width, and a length, the depth being from 40% to 60% of a thickness of the solar cell, the width being between 16 and 35 microns to create a plurality of scribe regions spatially disposed on the backside of the solar cell.

Abstract: In an example, a method includes providing a photovoltaic string comprising a plurality of from 2 to 45 strips, each of the plurality of strips being configured in a series arrangement with each other, each of the plurality of strips being coupled to another one of the plurality of strips using an electrically conductive adhesive (ECA) material, detecting at least one defective strip in the photovoltaic string, applying thermal energy to the ECA material to release the ECA material from a pair of photovoltaic strips to remove the defective photovoltaic strip, removing any residual ECA material from one or more good photovoltaic strip, aligning the photovoltaic string without the damaged photovoltaic strip, and a replacement photovoltaic strip that replaces the defective photovoltaic strip, and curing a reapplied ECA material on the replacement photovoltaic strip to provide the photovoltaic string with the replacement photovoltaic strip.

Abstract: This disclosure describes a method of calculating fluid distribution from a hydraulically fractured well, especially during a plug-and-perf hydraulic fracturing operation. The Distributed Acoustic Sensing (DAS) data is used to quantify the fluid distribution in separate perf clusters during fracturing, and the result can be used for completion design and optimization, hydraulic fracturing, and ultimately for oil and gas production.

Abstract: Ambulatory infusion pumps, pump assemblies, cartridges, baseplates, cannulas, insertion tools, and related components as well as combinations thereof and related methods.

Abstract: A drug delivery device includes a housing defining a shell and an inner volume, a container, a drive mechanism, a needle assembly, a fluid flow connection, and a backflow prevention mechanism. The container has an inner volume to contain a medicament to be administered to a user. The drive mechanism is at least partially disposed within the housing and exerts a force to urge the medicament out the container. The fluid flow connection is coupled to the container and the needle assembly and allows the medicament to flow from the container to the needle assembly to be administered. The backflow prevention mechanism is associated with at least one of the container, the fluid flow connection, or the needle assembly and includes at least one flow restrictor to restrict a fluid from flowing from the needle assembly to the container.

Abstract: A photovoltaic module with an improved interface includes a plurality of strings, each string comprising a plurality of PV strips coupled in series, each strip of the plurality of strips including first and second end strips disposed at opposing ends of the string and at least one middle strip disposed between the first and second end strips. Each strip has an aperture side, a back side, a single backside bus disposed on the back side of the strip, a plurality of conductive fingers disposed on the aperture side, a layer of electrically conductive adhesive that attaches the backside bus of every middle strip to the aperture side of an adjacent strip. The aperture sides of the plurality of strips are free from metallic materials between the plurality of conductive fingers, such that no bus bars are present on the aperture sides of the plurality of strips.

Abstract: The present invention pertains to the discovery that short chain aliphatic fatty acids, such as potassium sorbate, can be used in liquid-additive grinding compositions in the amount of at least 10%, more preferably at least 20%, and most preferably at least 30%, to mill carbonate materials into smaller particle size. The carbonate material can optionally be combined with another inorganic material in the grinding operation, such as limestone, lime, dolomites, talc, titanium dioxide, alumina, and kaolin, ceramics, and cement clinker. The use of the particularly described grinding additive composition are food-grade or food-contact approved, and are believed by the present inventors to resist the humectant behavior of the resultant ground particles which could in herently otherwise decrease efficiency of the particulate grinding process.

A fluid pathway connector may define a sterile fluid flowpath between the container and the insertion mechanism. Optionally, a cannula initially disposed about the needle may be included. The cannula may be retained in the patient at an injection site created by the needle after the needle is withdrawn from the patient. Methods of assembly and operation are also provided.
