  • Publication number: 20240188509
    Abstract: A seed development device for Psammochloa villosa using condensate water in desert areas includes: a cultivation box, a top surface of the cultivation box is connected to a cooler and condensate water collecting units through a support frame. Each condensate water collecting unit includes an outer frame, sleeve pipes, a middle frame, a cold air cavity, water collecting rods, a water collecting tank and a delivery pipe. The delivery pipe is connected to the cultivation box. When an outdoor temperature cannot complete condensation of water vapor, the cooler completes cooling of the cold air cavity and water collecting rods until condensate water collection is completed, water drops fall into the water collecting tank to complete water collection, which is used for water supplement of seed development of Psammochloa villosa, thus reducing the process of artificial water supplement and improving the development efficiency of seeds of Psammochloa villosa in desert areas.

  • Publication number: 20220370471
    Abstract: Hippocampal lesions, including synaptic failure, are a defining pathology of Alzheimer's disease (AD). However, the molecular mechanisms that underlie hippocampal synaptic injury in this neurodegenerative disorder have yet not been fully elucidated. In Current therapeutic efforts for the treatment of AD are not effective in correcting hippocampal synaptic deficits. It is disclosed that the interaction with amyloid beta (A?) induces dysfunction of growth hormone secretagogue receptor 1a (GHSR1?; ghrelin receptor), leading to suppressed GHSR1? regulation of hippocampal dopamine receptor D1 (DRD1) in AD hippocampi. The modulation of DRD1 by GHSR1? impacts hippocampal synaptic plasticity. The simultaneous application of a selective GHSR1? agonist and a selective DRD1 agonist mitigates A?-induced hippocampal synaptic injury and improves spatial memory in AD mouse models.

  • Patent number: 10075457
    Abstract: Methods and systems for integrating a sandboxing service and distributed threat intelligence within an endpoint security application are provided. According to one embodiment, The method includes file system or operating system activity relating to a file accessible to an endpoint system is monitored by an endpoint security application running on the endpoint system. The endpoint security application determines whether the file has been previously analyzed for a threat status. When a result of the determining is negative, then the endpoint security application requests the threat status by submitting the file to a remote threat analysis engine with a request to perform a threat analysis on the file. Based on the determined threat status, the endpoint security application selectively allows or disallows performance of the file system or operating system activity.

  • Publication number: 20130024466
    Abstract: Provided is a system event logging system for recoding a log of system events which relate to a process being monitored, the logging system having the aim of selectively recording system events that are necessary for purposes such as the reproduction of operations and excluding system events that are outside the intended purpose. Flag conditions and flag operation instructions are provided for each of the filters in a filter list, and the system event logging system uses the flag conditions as the conditions for applying the filters. When applying the filters, the logging system operates the flags according to the flag operation instructions. Thus, interrelated operation between the filters can be achieved by means of the flags, and also, interrelated operation can be achieved by means of the flags even between the processes performed for the system events.

  • Patent number: 6119797
    Abstract: The invention discloses a single cone earth boring bit which is adapted to be used for boring in oil fields, mining and geological prospecting. The single cone earth boring bit is composed of a bit body (1), gauge blocks (2), active cutting gauge teeth (4), passive gauge teeth (3) and knobby cone (6) etc. On the knobby cone (6), there are inserted wear-resistant teeth intermittently or successively, so as to make the wear resistance of the bit cutting system to be matched with the service life of the bearing. At the same time, gauge blocks (2) are provided on the bit body which may be directly made on or welded to the bit body. On the gauge blocks (2), there are inserted common carbide or wear-resistant active cutting gauge teeth (4) and the passive gauge teeth (3) to enhance the gauge-protecting effect of the bit. Such a single cone earth boring bit can significantly increase the footage of the bit and reduce the cost for drilling.
