Abstract: A processor device has a CPU cooperating with an input device and an output device, under control of stored instructions, and is arranged to receive service requests at the input device, assign service requests received in successive time periods to respective batches of requests; access stored service provider data to identify available service providers from among a pool of service providers; after completing the assignment of service requests to a batch, perform a matching process to endeavour to match each service request of the batch of requests to a service provider; and for each service provider to whom a match is made, output a notification of the respective potential match from the output device.

Abstract: A method, apparatus and system for detecting carbon emission-involved gas from a ruminant is provided, including: continuously receiving ear tag information of the ruminant in a monitoring range; determining an operation state of a feed supply system based on the ear tag information; and determining, based on collected emitted gas from the ruminant during eating, an emission rate of carbon emission-involved gas in the emitted gas when it is determined that the feed supply system is in a continuous operation state. In the method, apparatus and system, the ear tag information of the ruminant is detected to determine whether there is a ruminant in a detection area and feeding information of the ruminant, then the operation state of the feed supply system is controlled, and an intelligent information technology is used to acquire the emission rate of the carbon emission-involved gas matching the identity of the ruminant.

A method for enhancing an uptake of a target antigen by an immune cell, activating an immune cell, enhancing an innate immunity and/or a specific immune response and/or preventing and/or treating a tumor. A tumor vaccine for preventing postoperative recurrence of cancer.

Abstract: A carbon nanomaterial functionalized needle tip is modified with a low work function material. The needle tip is formed by combining a carbon nanomaterial with a material of a needle tip through a covalent bond. The interior or outer surface of the carbon nanomaterial is modified with a low work function material. The material of the needle tip is a metal which can be any of tungsten, iron, cobalt, nickel, and titanium. The carbon nanomaterial can be carbon nanocone or carbon nanotube. The tip of the carbon nanomaterial has the same orientation as the metal needle tip. The low work function material can be selected from metals, metal carbides, metal oxides, borides, nitrides, and endohedral metallofullerene. The carbon nanomaterial functionalized needle tip has a lower electron emission barrier, and can effectively reduce the electric field intensity required for electron emission, and improve the emission current and emission efficiency.

Abstract: Provided is a conical nano-carbon material functionalized needle tip, formed by assembling a nano-carbon material with a material of a needle tip by means of a covalent bond; and the material of the needle tip is a metal selected from one or more of tungsten, iron, cobalt, nickel and titanium. Further provided is a method for preparing the conical nano-carbon material functionalized needle tip. The conical nano-material functionalized needle tip has an outstanding interface formed by metal-carbide covalent bonds, and the orientation of the conical nano-material is matched with the axial direction of the metal needle tip (illustrated in FIG. 6). The proposed preparation method affords a robust interface and avoids the potential pollution to the nano-material caused during the deposition of fixing materials, such as carbon or platinum or the like, in other preparation methods.

Abstract: This invention provides a composition of polyhydroxylated metallofullerene compound and its application in the preparation of antitumor pharmaceutical. In one embodiment, metallofullerol comprising the formula, M@C2m(OH)x, wherein M is selected from rare earth elements such as La or Gd; m is carbon atoms of 41 or 30; x is a number of hydroxyl group of from 10 to about 50. Actually, due to the reset of the neighboring hydroxyl, the numbers of O and H in Carbon cage are different, formula are thus written as M@C2mOxHy. Comparing to the clinical anticancer drugs such as Paclitaxel, Cyclophosphamide, and Cisplatin, metallofullerol of M@C2m(OH)x or M@C2mOxHy has superior advantages of higher antitumor efficiency, low dosage, low toxicity, and better biocompatibility.
