Abstract: Methods, apparatus, and processor-readable storage media for automatically generating task-based and limited-privilege user security credentials are provided herein. An example computer-implemented method includes processing a request for user security credentials against one or more predetermined security parameters associated with at least one network; generating, based on the processing of the request, at least one set of user security credentials comprising one or more combinations of multiple randomly selected characters; configuring one or more attributes associated with the at least one set of user security credentials in connection with the at least one network, wherein the one or more attributes comprise at least one of one or more task-related attributes and one or more privilege-related attributes; and performing one or more automated actions based on the one or more configured attributes and/or implementation of the at least one set of user security credentials by one or more users.

Abstract: Stapling assemblies for use with a surgical stapler are provided. In one exemplary embodiment, the stapling assembly includes a cartridge having a plurality of staples disposed therein and a non-fibrous adjunct formed of at least one fused bioabsorbable polymer and configured to be releasably retained on the cartridge. Adjunct systems for use with a surgical stapler are also provided. Surgical end effectors using the stapling assemblies are also provided. Methods for manufacturing stapling assemblies and using the same are also provided.

Abstract: In various examples, a table recognition model receives an image of a table and generates, using a first encoder of the table recognition machine learning model, an image feature vector including features extracted from the image of the table; generates, using a first decoder of the table recognition machine learning model and the image feature vector, a set of coordinates within the image representing rows and columns associated with the table, and generates, using a second decoder of the table recognition machine learning model and the image feature vector, a set of bounding boxes and semantic features associated with cells the table, then determines, using a third decoder of the table recognition machine learning model, a table structure associated with the table using the image feature vector, the set of coordinates, the set of bounding boxes, and the semantic features.

Abstract: Sensors for sensing/measuring one or more analytes in a chemical environment. Each sensor is based on a semiconductor structure having an interfacial region containing a two-dimensional electron gas (2DEG). A catalyst reactive to the analyte(s) is in contact with the semiconductor structure. Particles stripped from the analyte(s) by the catalyst passivate the surface of the semiconductor structure at the interface between the catalyst and the structure, thereby causing the charge density in the 2DEG proximate the catalyst to change. When this basic structure is incorporated into an electronic device, such as a high-electron-mobility transistor (HEMT) or a Schottky diode, the change in charge density manifests into a change in an electrical response of the device. For example, in an HEMT, the change in charge density manifests as a change in current through the transistor, and, in a Schottky diode, the change in charge density manifests as a change in capacitance.

Abstract: Methods and systems to determine a concentration of bromide ions in an aqueous sample are disclosed. The method involves the oxidation of bromide ions to bromine, followed by bromination of a colored or fluorescent reporter compound which may be detected by spectrophotometric means. The relative change in color or fluorescence upon bromine binding to the reporter compound may then be used to determine a quantitative concentration of bromide ions in the sample. The system utilizes a photocatalytic coating in a sample chamber, a source of reporter compound in fluid communication with the sample chamber, light sources that may activate the photocatalyst and excite the reporter compound, an optical detection unit capable of receiving a light signal from the second light source after it has passed through the sample chamber, and various pumps, valves or injection syringes that regulate the flow of sample and reporter compound into and out of the sample chamber.
