Abstract: This invention provides a preparation, composition, product, and application of a photo-coupled synergistically crosslinked hydrogel material. The preparation includes dissolving Component A including a photosensitive polymer derivative having o-nitrobenzyl phototriggers and Component B including a polymer derivative having amine or alkene (double group) or sulfhydryl group in a biocompatible medium to obtain solution A and solution B, respectively; mixing the solution A and solution B homogeneously to obtain a hydrogel precursor solution; initiating photo-coupled synergistic crosslinking under an irradiation of a UV light to form the hydrogel. The irradiation causes the o-nitrobenzyl phototriggers to generate an aldehyde group/keto group or a nitroso group to initiate photo-coupled synergetic crosslinking. The photo-coupled synergistically crosslinked hydrogel has applications in tissue engineering, regenerative medicine, 3D printing and as a carrier of cell, protein or drug.

Abstract: A flame arrester includes a flame arrester housing that has a fluid channel defined therein and an inlet and an outlet which are communicated with the fluid channel. The fluid channel is internally provided with a flame arresting unit for preventing flame propagation One side of the flame arresting unit is provided with a deformation unit configured to deform when the internal temperature of the fluid channel reaches a preset temperature to reduce the flow area of the fluid channel towards the outlet. The deformation unit is provided on one side of the flame arresting unit, and when continuous combustion is formed at the flame arresting unit, the deformation unit deforms to reduce the flow area of the fluid channel on the surface of the flame arresting unit to increase a gas flow rate to move the flame is away from the surface of the flame arresting unit.

Abstract: The disclosed technology teaches delivering scarce test equipment resources to a user within a test organization: receiving a test graph that specifies equipment capabilities needed, by class and times when the capabilities are needed. The technology includes maintaining an inventory of equipment resources and capabilities, by class, and responsive to the user invoking the graph, scheduling the needed equipment: identifying alternative resources responsive to the need and selecting a group of resources to schedule; bundling the group of resources to schedule into an immediate bundle needed to start the test and a deferred bundle needed later, after the start of the test; and queuing a deferred bundle reservation for a later time, after the scheduled start of the test. During the test, the technology includes notifying the user of availability of the equipment resources in the deferred bundle when they become available and marking the deferred bundle as in use.

Abstract: A response map descriptively modeling the textual format of a test response of a system verification test is created without a priori understanding of the format of the given response. Such response map is applied to the test response or other similar test responses that share the same format. More specifically, a method of identifying and extracting one or more formats of textual data included in test responses from system verification testing of a system under test is provided, by receiving a first test response including first textual data in one or more formats, generating a response map descriptively modeling the first test response without a priori information of the one or more formats, and applying the response map to a second test response to identify and extract second textual data from the second test response. The second textual data is also in the one or more formats.
