Performance of deep learning object detection technology in the detection and diagnosis of maxillary sinus lesions on panoramic radiographs

Objective: The first objective of this study was to determine the performance of detection techniques in-depth learning objects in the detection of the maxillary sinus in panoramic radiographs. The second objective is to clarify the classification performance of the maxillary sinus lesions compared to healthy maxillary sinus.


Methods:
Data imaging for the maxillary sinuses healthy (587 sinus, Class 0), inflammation of the maxillary sinus (416 sinus, Class 1), cyst area of ​​the maxillary sinus (171 sinus, Class 2) is assigned to the training, testing 1, and testing of two sets of data , A learning process 1000 times with training images and labels is done by using DetectNet and learning model created.

The test 1 and test 2 pictures are applied to the model, and the sensitivity of detection and false positive rate per image is calculated. The accuracy, sensitivity and specificity are determined to differentiate groups of inflammation (Class 1) and cyst group (Class 2) with respect to the healthy group (Class 0).


Results: The sensitivity detection healthy (Class 0) and inflamed (Class 1) the maxillary sinus 100% for both tests 1 and 2 test data sets, while they are 98 and 89% for cysts of the maxillary sinus area (Class 2). false positives per image almost 0:00. Accuracy, sensitivity and specificity for the diagnosis of maxillary sinusitis is 90-91%, 88-85% and 91-96%, respectively; for cysts of the maxillary sinus area, these values ​​are 97-100%, 80-100%, and 100-100%, respectively.


Conclusion: Much learning can reliably detect and identify the maxillary sinus cysts maxillary sinusitis and maxillary sinus area.


Advances in knowledge: This study uses object detection techniques in lean indicates that the maxillary sinus detection sensitivity is high and the performance of the maxillary sinus lesion identification is ≧ 80%. In particular, the performance of the identification of sinusitis is ≧ 90%.

The effect of the combination of big data technology on the learning platform with deep Spark on the efficiency of the elevator safety monitoring

To effectively minimize lift safety accidents, big data technology combined with in-depth learning technology platform based on Spark. This study was the first to introduce the relevant theories elevator safety monitoring technology, data technology that is large and deep learning technology. Then, the type of error that occurred in the state run the elevators were identified, and a finite state machine model is established.

An elevator error method based on monitoring the Spark platform is proposed, which is a finite state machine (FSM), and the results of safety monitoring of the elevator fault evaluated. Based on the study, a model error warning elevator constructed and evaluated the performance of early warning.

The results showed that the study can realize real-time and effective monitoring in the operating country elevators, and can determine the type of fault lift by binding to abnormal operating state with an appropriate error. Feasibility elevator safety monitoring efficiency is evaluated based on three indices: the mutual information, accuracy, and false positives.

Description: p38 is a protein encoded by the MAPK14 gene which is approximately 41,2 kDa. p38 is localised to the cytoplasm and nucleus. It is involved in activated TLR4 signalling, the IL-2 pathway, toll-like receptor signalling pathways, the VEGF signalling pathway and 4-1BB pathway. This protein falls under the MAP kinase family. It acts as an integration point for multiple biochemical signals, and is involved in a wide variety of cellular processes such as proliferation, differentiation, transcription regulation and development. This kinase is activated by various environmental stresses and proinflammatory cytokines. p38 is expressed in the brain, heart, placenta, pancreas and skeletal muscle. Mutations in the MAPK14 gene may result in patellar tendinitis and lumbosacral lipoma. STJ94878 was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen. This polyclonal antibody detects endogenous levels of p38 protein.
