The invention discloses a pulmonary nodule false positive sample inhibition method based on 3D CNN (convolutional neural networks). The pulmonary nodule false positive sample inhibition method comprises steps that 1) 3D reconstruction of a lung CT is carried out by adopting interpolations; 2) according to a to-be-inhibited sample coordinate, a cube of a fixed size is cut from reconstruction data, and is normalized, and then positive samples are expanded, and then negative samples and positive samples are used as the training data of the 3D CNN together; 3) a training sample is used to train a 3D CNN model; 4) during the model training, weighting correction of a standard loss function is carried out, and different weights are provided for the negative samples and the positive samples. A training network is cycled and iterated, and finally, the 3D CNN model is acquired. The method based on the 3D CNN training model is advantageous in that on one hand, the three-dimensional characteristics of the lung CT data are effectively used, and sample information is reflected to the greatest extent; and on the other hand, the weighting of the loss function is carried out during the model training, a problem of true and false sample imbalance is solved, and therefore the model having good pulmonary nodule identification effect is acquired after the training.

The invention discloses an evaluation method for the emergency lifesaving performance of an inflatable life jacket for aviation. The method comprises the following steps: according to a determined subject, carrying out life jacket packaging bag take-out time testing, life jacket packaging bag opening time testing, and life jacket wearing time testing to obtain a life jacket wearing index Idon; carrying out life jacket buoyancy force testing on the life jacket and life jacket thermal resistance testing of close contact with the body core parts to obtain an in-water lasting survival index Iwater; carrying out life jacket indicator distance testing on the life jacket to obtain an indicator rescue index Ipos; and on the basis of the Idon, the Iwater and the Ipos, acquiring an emergency rescueindex LSP of an inflatable life jacket for aviation to evaluate the emergency lifesaving performance of the inflatable life jacket for aviation. According to the invention, the emergency lifesaving performance of an inflatable life jacket for aviation is integrated into the product of the life jacket wearing index, the in-water lasting survival index, and the emergency rescue index, so that the quantitative evaluation of the emergency lifesaving performance of the life jacket is realized and consumers are guided to go shopping.

The invention discloses a multi-point detection and trigger type intelligent window breaking device for automobiles falling into water, which includes a circuit protection box and a mechanical protection box; a water drop detection component, a power supply and an MCU are arranged in the circuit protection box; the water drop detection component includes a water drop The detection board (18), the outer end surface of the water drop detection board (18) exposes the circuit protection box and is provided with several water drop sensors (17), and each water drop sensor (17) transmits its own detection signal to the MCU through the A / D conversion circuit Inside, after the MCU is processed, the relay is connected to the push-pull electromagnet of the elastic window breaking component in the mechanical protection box through the amplifying circuit, and the power supply supplies power to the MCU; at least two groups of elastic window breaking components are arranged side by side in the mechanical protection box (14) . The invention adopts an independent power supply design, which has no connection with the battery of the car, and adopts a waterproof design, so that the broken window device can be guaranteed to work normally even after the car falls into water. Improve the success rate of smashing the tempered glass of the car body.

The present invention relates to compositions and methods for treating a microbial infection in a subject, in particular methods of administering a gelsolin agent and an antimicrobial agent to produce a synergistic therapeutic effect against a microbial infection in a subject. The invention also relates to methods for treating a viral infection in a subject, comprising methods comprising delayed ed-administration methods and / or synergistic methods.

The invention belongs to the technical field of the immunology, and relates to a detection kit for the severe septicopyemia and the acute liver failure. The detection kit comprises a sodium citrate contained anticoagulant tube, an erythrocyte lysate, a PBS solution, a CD45 human monoclonal antibody, a CD14 human monoclonal antibody, a CD16 human monoclonal antibody, and a 1% paraformaldehyde fixing solution. The detection kit can detect the peripheral bloods of septicopyemia and acute / acute-on-chronic liver failure patients through detecting the monocyte differentiation capability in order to determine the prognosis of the above diseases. Detection results show that the obstacles of the monocyte differentiation capability of the diseases still exist; and the peripheral blood monocyte differentiation repression is closely related with the disease prognosis because the mortality of monocyte differentiation repression patients obviously increases and the monocyte differentiation repression patients can survive after the disappearance of the differentiation repression. The detection kit provides positive meaningful reference data for further treatment schemes.

The location capable mobile handset allows the user to provide a call recipient with the location of an unsuccessful attempted emergency call. In one specific example, the call may be an E911 call toa PSAP dispatcher. Additionally, the call may be to a towing service, or to a family member or friend to request assistance. The call may be any call that a mobile handset user wants to send locationinformation to the party that has been called. Returning to the E911 call example, the location information reported to dispatcher can include the location of initial E911 call, current location during a successful E911 call, or ground track information from the initial location to the current location. When an E911 call is unsuccessfully attempted, the mobile handset stores the location of the mobile handset at that time. This information can later be transmitted when the mobile handset is in a coverage area. Additionally, the mobile handset can auto-dial 911 upon entering a service area after an unsuccessful E911 attempt. Alternately the user can be prompted to initiate an E911 call when the mobile handset enters a service area.

The present invention relates to the technical field of automatic driving, and discloses an automatic driving system capable of monitoring the driver's safety state, including a state collection module, an information processing module and an action execution module. The state collection module obtains the driver's current sign state information, and The sign status information is sent to the information processing module, and the information processing module compares the acquired sign status information with the preset information and outputs a judgment instruction, and the action execution module controls the execution unit to execute the rescue strategy according to the judgment instruction. The present invention monitors the driver's physical sign information in real time, and when it is found that the driver is unable to operate the vehicle, it can call the automatic driving system to take over the vehicle in time, and execute the corresponding rescue strategy to rescue the driver, thus reducing driving time. When the driver is in a sudden state and loses the ability to control the vehicle, the probability of a vehicle driving accident occurs, and at the same time, the driver can be rescued in time through relevant rescue strategies.
