  • Publication number: 20260022380
    Abstract: A method of inhibiting growth of cancerous cells involves contacting the cancerous cells with a very long chain fatty acid elongase 6 inhibitor (ELOVL6i). The cancerous cells are KRAS dependent. The ELOVL6i reduces a level of KRAS expressed by the cancerous cells, relative to a level thereof prior to contacting of the ELOVL6i, thereby inhibiting the growth of the cancerous cells.

  • Publication number: 20250334487
    Abstract: A system for monitoring a tension in a track of a work machine includes one or more sensors coupled to the work machine. A sensor, of the one or more sensors, is configured to obtain a distance information related to a distance between the sensor and the track of the work machine. The sensor includes a pulse Radio Detection and Ranging (RADAR) sensor. The system includes a controller including at least one memory and at least one processor. The memory is configured to store an expected distance between the sensor and the track of the work machine. The processor is configured to determine an actual distance between the sensor and the track of the work machine, based on the distance information obtained from the sensor and determine, based on the actual distance being greater than the expected distance, that the tension in the track is below a tension threshold.

  • Patent number: 11486508
    Abstract: An actuator sub for generating hydraulic pressure having a sub housing which includes (i) an outer surface, (ii) a main flow passage extending though the sub housing, and (iii) a wall space formed between the main flow passage and the housing outer surface. At least a first hydraulic tube is position in the wall space and an equalization port is configured to transmit pressure in the main flow passage to the first hydraulic tube. A drive motor driving an bi-directional hydraulic motor, are positioned in the first hydraulic tube, with the hydraulic motor being configured to output fluid to a fluid outlet of the first hydraulic tube, and the hydraulic motor, when not under power, allowing the reverse flow of fluid through the hydraulic motor. The actuator sub includes the absence of a check valve along a path carrying fluid between the hydraulic motor and the outlet of the second hydraulic tube.

  • Publication number: 20060199893
    Abstract: Systems and methods are provided for compounding a thermoplastic melt for molding articles, the melt being reinforced with reinforcing fibers. The thermoplastic material is plasticized with an adhesion promoting agent to obtain an initial melt to which the reinforcing fibers are added. The thermoplastic material forms bonds to bond reception sites on the reinforcing fibers to obtain an intermediate melt to which one or more desired additives, such as a colorant, are then added to obtain the final melt. By forming the intermediate melt without the presence of the one or more desire additives, competition between the one or more desired additives and the thermoplastic material for the bond reception sites is prevented, as is damage to the reinforcing fibers from abrasives in the one or more desired additives. Articles molded with the resulting final melt have improved mechanical properties compared to articles made with prior art methods and systems.

  • Patent number: 6882237
    Abstract: A voltage controlled oscillator generates an output signal whose frequency varies as a first function of a control voltage applied to a control terminal. The voltage controlled oscillator has a wide range of frequency of operation. A gain adjust circuit adjusts the gain of the voltage controlled oscillator such that the first function varies as a second function of the gain. In a preferred embodiment the gain adjust circuit includes a variable impedance that may be external or integrated onto a common chip with the oscillator core.
