Abstract: Embodiments may relate to group addressed frame delivery over multi-link systems. Systems and methods are configured for identifying, by an access point (AP) multilink device (MLD) in a wireless network, a first sequence number space (SNS) that is to be used by the AP MLD to transmit data to a non-AP MLD over a first communications link and a second communications link, wherein frames with identical data that are transmitted over the first and second communications links will have an identical first SN based on the first SNS; identifying, by the MLD in the wireless network, the first SN based on the first SNS; and transmitting, by the AP MLD in the wireless network, a frame that includes the data to the non-AP MLD based on the first SN.

Abstract: Disclosed herein are system, method, and computer program product embodiments for identity obscuration of a station (STA) connected to a wireless network to prevent the tracking of the STA. Embodiments include a STA configured to establish a security association with an access point (AP) based on an original long term identity for the station and an identity of the AP. The STA can transmit a new long term identity for the STA to the AP based on the security association. The STA can then transmit a request frame to change the original short term identity assigned to the STA to the AP. The STA can receive a response frame from the AP. The response frame can include a new short term identity assigned to the station by the AP. The STA can then map its new long term identity to its new short term identity assigned by the AP.

Abstract: Disclosed in the disclosure is a method for detecting acetaldehyde in wine samples using fluorescent probes, belonging to the field of wine quality control. The detection method of the disclosure is used for measuring acetaldehyde in wines based on fluorescent probes. Under the acidic condition of pH=2.0, the specific binding between the fluorescent probe and acetaldehyde is realized according to the principle of photoelectron induced transfer. The fluorescent probe has a good linear relationship with the concentration of acetaldehyde in a range of 0-200 mg/L, the limit of detection (LOD) is 3.6×10?8 mol/L, and the recovery rate of samples is 94.02-108.12%. The detection method has the advantages including low cost, wide linear range, high sensitivity, and being fast and accurate. The fluorescent probe is successfully applied to the detection and analysis of wine samples and samples in a beer fermentation process.

Abstract: An electronic device (such as an access point) that performs a remedial action is described. This electronic device may transmit, using a first radio in the electronic device, a physical layer convergence protocol (PLCP) protocol data unit (PPDU) to a recipient electronic device on a first link between the electronic device and the recipient electronic device, where the PPDU includes a PPDU preamble and a set of media access control (MAC) protocol data units (MPDUs). Then, the electronic device may receive, using a second radio in the electronic device, feedback from the recipient electronic device on a second link between the electronic device and the recipient electronic device. Next, the electronic device may perform the remedial action based at least in part on the feedback. For example, the electronic device may abort the PPDU transmission and/or retransmit one or more of the set of MPDUs.

Abstract: The present invention discloses catalyst and method for producing light olefins directly from synthesis gas by a one-step process, and particularly relates to method and catalyst for directly converting synthesis gas into light olefins by a one-step process. The provided catalysts are composite materials formed of multicomponent metal oxide composites and inorganic solid acids with hierarchical pore structures. The inorganic solid acids have a hierarchical pore structure having micropores, mesopores and macropores. The metal composites can be mixed with or dispersed on surfaces or in pore channels of the inorganic solid acid and can catalyze the synthesis gas conversion to a C2-C4 light hydrocarbon product containing two to four carbon atoms. The single pass conversion of CO is 10%-60%. The selectivity of light hydrocarbon in all hydrocarbon products can be up to 60%-95%, wherein the selectivity of light olefins (C2?—C4?) is 50%-85%.
