Abstract: Embodiments of the invention are directed to computer-implemented methods of analyzing a web-based software application. A non-limiting example of the computer implemented method includes generating, using a processor system, a set of to-be-tested element-event pairs of the web-based software application. A set of compatibility tests is received at the processor system, where the set of compatibility tests is operable to perform compatibility testing of a corresponding set of element-event pairs. A comparison is performed between the set of to-be-tested element-event pairs and the corresponding set of element-event pairs. A compatibility testing recommendation is generated based at least in part on a result of the comparison.

The present invention involves micro-dissection of bronchial tissues to expose the cilia-rich epithelium for ex vivo virus infection, along with a semi-quantitative approach for analyzing virus tropism and replication competence.

Abstract: The present invention relates to a non-invasive method for generating human three-dimensional nasopharyngeal organoids, including non-invasively collecting nasopharyngeal swab samples; culturing the samples in a matrix with niche factors; and obtaining the three-dimensional human nasopharyngeal organoids after culturing the samples in the matrix for 14-21 days. The three-dimensional human nasopharyngeal organoids are then dissociated into a single cell suspension for the creation of human two-dimensional nasopharyngeal organoids. The present nasopharyngeal organoids and their preparation method enable the rapid expansion of stem cells to form organoids within a short period of time. By combining organoid passaging techniques, a sufficient number of organoids can be obtained within a limited time for research and experimental operations.

Abstract: This document describes techniques and devices to synchronize communications between devices in a wireless mesh network. Based on the requirements of an end device that sleeps (e.g., is out of communication with the wireless mesh network) for periods of time, the end device indicates to a parent wireless mesh network device that the end device wants to configure operations in a synchronized-reception mode, which causes the parent device to reply with an indication of the clock accuracy of the parent device. The end device uses the clock accuracy of the parent device to determine parameters for synchronized-reception and transmits the parameters to the parent device. The end device activates its receiver based on the parameters to receive data from the parent device.

Abstract: Techniques and devices for determining a preferred physical layer for communication by a node in a Thread network are described. The node transmits a first IPv6 over Low power Wireless Personal Area Networks, 6LoWPAN, frame to a neighbor node using a first physical layer and transmits the first 6LoWPAN frame to the neighbor node using a second physical layer. The node determines a first preference value for the neighbor node using the first physical layer and determines a second preference value for the neighbor node using the second physical layer. The node compares the first preference value and the second preference value to determine the preferred physical layer for communication and transmits a second 6LoWPAN frame to the neighbor node using the preferred physical layer.
