  • Patent number: 12285427
    Abstract: This invention establishes a new paradigm for treatment of Parkinson's disease (PD) by eliminating senescent cells that reside in or around the site of the disease pathophysiology. Exposure of test subjects to the herbicide paraquat (PQ) increases the risk for developing Parkinson's disease. The data in this disclosure show that PQ induces a senescence arrest and SASP in astrocytes, in culture and in vivo in mice, and senescent cell markers were present in astrocytes in midbrain tissue from PD patients. In a transgenic mouse model, senescent cell ablation protected against PQ-induced PD-like neuropathology. Removal of senescent cells from affected sites using small molecule agents that specifically target senescent cells can help prevent or ameliorate signs and symptoms of the disease.

  • Patent number: 12273903
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for adjusting a packet duration for triggered uplink (UL) transmissions to an access point (AP) from one or more stations (STAs). In one aspect, the AP may estimate an amount of data that a STA has queued for UL transmission and select the packet duration based on the estimated amount of queued UL data. The AP may transmit a trigger frame that solicits UL data from the STA and indicates the selected packet duration. In response, the AP may receive an UL packet from the STA and determine an amount of UL data queued in the STA based on the UL packet. In some implementations, the AP may selectively adjust the packet duration for UL transmissions based on the UL packet, the determined amount of UL data queued in the STA, or both.

  • Patent number: 12267726
    Abstract: Systems and methods for selectively enabling multi-user (MU) communications are disclosed. In some implementations, an access point (AP) obtains packets associated with a traffic flow, and obtains at least one of service-level agreement (SLA) parameters associated with the traffic flow, attributes of the traffic flow, or network parameters associated with a basic service set (BSS) that includes the AP. The AP provides an indication of whether the traffic flow is suitable for transmission as a single-user (SU) multiple-input multiple output (MIMO) (SU-MIMO) communication, as an MU-MIMO communication, as an orthogonal frequency division multiple access (OFDMA) communication, or as a partial bandwidth (BW) MU-MIMO communication to a WLAN subsystem of the AP, the indication being based on one or more of the SLA parameters, the traffic flow attributes, or the network parameters. The AP initiates transmission of the one or more packets based on the indication.

  • Publication number: 20240245967
    Abstract: A rotating climbing wall can include a frame assembly with uprights forming rails. Slats of a slat assembly can include coupling blocks that are configured to ride along the rails of the uprights. At least one upright can include a power rail that extends alongside the rail. Electrical contacts can be integrated into the coupling blocks to form an electrical connection with the power rail as the respective slats ride along the rails. The electrical connection can be used to power lights that are integrated into the slats and that illuminate holds. The rotating climbing may include actuators that automatically tension chains used to rotate the climbing surface of the rotating climbing wall. The actuators, which may be linear actuators, can detect a level of tension in the chains and, if the tension is below a threshold, increase the distance between sprockets that drive the chains to increase the tension.
