Abstract: Various schemes pertaining to encoding and transmit power control for downsized trigger-based (TB) physical-layer protocol data unit (PPDU) transmissions in next-generation WLAN systems are described. A station (STA) receives a trigger frame indicating an allocated resource unit (RU) of a first size. The STA performs channel sensing responsive to receiving the trigger frame. In response to detecting at least one subchannel being busy from the channel sensing, the STA performs a downsized trigger-based (TB) transmission with a downsized RU or multi-RU (MRU) of a second size smaller than the first size by utilizing downsized RU or MRU allocation information while maintaining a value of each of one or more parameters unchanged in an encoding process to perform the downsized TB transmission.

Abstract: A field of asymmetric catalytic synthesis, and in particular a preparation method for a high optical indoxacarb intermediate includes reacting 5-chloro-2-methoxycarbonyl-1-indanone ester (or indanone ester for short) with an oxidizing agent in the presence of a chiral Zr-salen polymer to obtain an indoxacarb intermediate (2S)-5-chloro-2,3-dihydro-2-hydroxy-1-oxo-1H-indole-2-carboxylic acid methyl ester. The yield is stabilized between 86% and 90%, and the S-enantiomer content is up to 99%. Such catalyst can replace catalysts such as cinchonine, and greatly increase the content of the effective S-enantiomer of the indoxacarb, so that the content of the hydroxyl intermediate S-enantiomer of the indoxacarb is raised from 75% to 99% or more. In addition, the chiral Zr-salen polymer catalyst is recycled without retreatment, and can be recycled at least 5 times or more, greatly reducing the production cost and laying a foundation for the industrial production of high quality indoxacarb.

Abstract: The design for modern graphical interfaces generated by an application under test (AUT) can take many forms. A codeless testing system reads the output generated by the AUT to identify components, however, scroll bars may be present but in a form that is not reliably identified. As a result, an AUT may comprise scrollable graphical elements that are not identified as such resulting in the performance of tests that are incomplete. By applying a middle button click event, an associated pointer changes form and reveals an associated graphical element to comprise a scrollable element. When the pointer change occurs, testing directed to the scrollable element is then included to perform a more complete testing of the features of the AUT.
