Abstract:
This disclosure provides systems, methods, and apparatus related to locally doping two-dimensional (2D) materials. In one aspect, an assembly including a substrate, a first insulator disposed on the substrate, a second insulator disposed on the first insulator, and a 2D material disposed on the second insulator is formed. A first voltage is applied between the 2D material and the substrate. With the first voltage applied between the 2D material and the substrate, a second voltage is applied between the 2D material and a probe positioned proximate the 2D material. The second voltage between the 2D material and the probe is removed. The first voltage between the 2D material and the substrate is removed. A portion of the 2D material proximate the probe when the second voltage was applied has a different electron density compared to a remainder of the 2D material.
Abstract:
An inflatable lifesaving device is designed to provide a user with an apparatus to escape a high rise building in emergency situations in a sufficiently rapid manner. It is simply composed of a hemisphere including a plurality of independent cell airbags, internal hoses, and check valves, a parachute integrated with the hemisphere, an air supply system, an external hose, a quick release hose coupler, a harness mounted on the body of the user, a connection rope that connects the harness to the inside of the building, a rope quick release to separate the connection rope, a descent rope, a backpack. To operate the inflatable lifesaving device, the user wearing the harness with the backpack exits a window or a balcony with the harness connected to the inside of the building through the connection rope with the release device. The air supply system is then turned on and high pressure air inflates and opens up the hemisphere and the parachute so that they are gradually formed from the back of the user to the front, and eventually the user is surrounded by them. after that, the external hose and the connection rope are released. As a result, the user will move down with the hemisphere and the parachute.
Abstract:
A heat-exchange device comprises a first heat exchanger defining an upper end and a lower end. A second heat exchanger defines an upper end connected to the upper end of the first heat exchanger and a lower end spaced apart from the lower end of the first heat exchanger in a substantially longitudinal direction such that a predetermined angle between the first heat exchanger and second heat exchanger is between about 0 and 180°. A wind-guide member is disposed between the first heat exchanger and second heat exchanger for guiding wind toward the first heat exchanger and second heat exchanger.

Abstract:
Network infrastructure management may be provided. First, administrative tools associated with a plurality of network topologies may be provided in a management console. Providing the administrative tools may comprise providing a first set of tools associated with a first network topology in the console. The first network topology may be an on-premises topology. Providing the administrative tools may also comprise providing a second set of tools associated with a second network topology in the console. The second network topology may be a cloud topology. Next, communications for the plurality of network topologies may be established to manage the plurality of network topologies through the management console. Establishing the communications for the plurality of network topologies may comprise establishing a first communications channel between the first network topology and the console. In addition, establishing the communications may comprise establishing a second communications channel between the second network topology.
Abstract:
A method and a network device for preventing service disruption during a restart of a line card. The line card including a CPU control system and a forwarding system. Information on the CPU control system is stored in a predetermined storage and a flag is set prior to the restart of the line card. The stored information includes configuration information of the forwarding system and protocol state information of the CPU control system. The CPU control system is restarted while the forwarding system is maintained in a state of providing forwarding service. Upon detecting the flag is set during the restart of the CPU control system, the stored information is restored on the CPU control system.
Abstract:
A marker for the detection of liver cancer and application of the marker thereof. The application includes use of cytochrome p450 family 17 subfamily A polypeptide 1 (CYP17A1 protein) in the preparation of diagnostic reagents or kits for the detection of liver cancer kit. Studies have shown that CYP17A1 expression levels are higher in liver cancer tissues than in the adjacent healthy tissues, and the amount of CYP17A1 in sera of liver patients is significantly higher than that of healthy human population. Therefore, CYP17A1 can be used as a marker for the diagnosis of liver cancer (especially serological diagnosis).

Abstract:
A method of arbitrating requests from bus masters for access to shared memory in order to reduce access latency, comprises looking ahead into currently scheduled requests to the shared memory and predicting latency of the requests based on characteristics of the currently scheduled requests, such as increasing page hit rate, or balancing read and write traffic. The requests are scheduled based at least in part on the predicted latency.
