Abstract: A monitoring system detects and measures a quantity of radical particles within a gas. A test chamber is coupled to a flow channel that transmits a gas. The test chamber defines an aperture connecting the test chamber and the flow channel, and the aperture permits a subset of the gas to enter the test chamber from the flow channel. An ionizer is positioned within the test chamber and generates radical ions from radical particles of the subset of the gas. A mass spectrometer measures a quantity of the radical ions, thereby providing a measurement of the radical particles in the gas.

Abstract: This specification discloses data transmission methods and apparatuses, storage media, and electronic devices. An example method includes in response to receiving a connection request from a client device, determining, by a server, whether the connection request comprises session state information. The session state information comprises parameters and a session identifier, where data transmission between the server and the client device is performed through a session based on the parameters. In response to determining that the connection request comprises the session state information, the server resumes the session based on the session state information, and performs data transmission with the client device through the resumed session. In response to determining that the connection request is absent of the session state information, the server creates a session between the server and the client device, and sends session state information corresponding to the created session to the client device.

Abstract: The present disclosure provides a medical hyperspectral image (MHSI) classification method based on a fast fully convolutional network (FCN), and relates to the technical field of MHSIs. The MHSI classification method includes: preprocessing and sampling an MHSI to obtain a training sample set; inputting the training sample set into an encoder-decoder-based FCN to train the MHSI; and inputting a to-be-classified pixel of the MHSI into a trained encoder-decoder-based FCN to obtain a classification result.

Abstract: A method of measuring an atmosphere in a guest vacuum chamber of a vacuum tool includes measuring a first composition of the atmosphere in the host vacuum chamber using a residual gas analyzer (RGA). The host and guest vacuum chambers are not coupled during the measuring of the first composition. The host vacuum chamber is coupled to the guest vacuum chamber, so the atmospheres in each can mix in the host vacuum chamber. A second composition of the atmosphere in the host vacuum chamber is measured using the RGA after the chambers are coupled. Using a processor, a composition of the guest atmosphere is automatically determined using the measured first and second compositions. A vacuum tool can include the host and guest chambers, the valve, the RGA, and a processor configured to control the valve to carry out this or other methods.
