Cox proportional hazards mode was applied, and the C-index of the combined model was 0.719. Prediction accuracy of up to 0.844 on the internal validation set. Of course, this research has limitations. To improve screening performance, researchers chose AI model with high sensitivity but low ...
To characterize the biological functions of the well-predicted genes in our model, we carried out gene set analysis. First, we performed gene set variation analysis (GSVA) to assess the predicted gene expression values at the pathway level32. Second, we conducted hyper-geometric tests using the...
Other databases of images, more permissive regarding the terms of use, that have been used in emotional research are the Geneva Affective Picture Database (GAPED)25, EmoPics26, Open Affective Standardized Image Set (OASIS)27. These databases vary in the number and quality of the images, and ...
Further, most artificial intelligence (AI)-based pathology biomarkers mainly focused on different aspects of prediction, lacking the exploration of underlying biological mechanism. In the present study, we sought to establish a fully automated histopathological slide analysis pipeline that can use original...
15-17 Studies have also shown associations between the presence or absence of specific built environment elements and certain health outcomes. Associations between neighborhood racial and ethnic composition and health are not due to biological differences between racial and ethnic groups. Rather, these ...
Stone - Proceedings of the National Academy of Sciences, India - Section A 被引量: 21发表: 2012年 Optimization of Neural Field Models There is a growing interest in using dynamic neural fields for modeling biological and technical systems, but constructive ways to set up such models are still...
most famous was Dr. David Kelly who died in July 2003. Working for the Mossad, Kelly orchestrated the defection of Russian microbiologist Vladimir Pasechnik, who had been working on a doomsday biological weapon capable of destroying one third of the planet's population. How would it be ...
We assessed the prognostic value of our novel risk group using the univariate and multivariate Cox proportional hazards models. In multivariate analysis, cancer-stage grouping and age at diagnosis were added to adjust the hazard ratio for the novel risk group. The outcome was the overall survival ...
Mining is one of the engineering activities that has the strongest impact on the geological environment, and its negative impact on desertification in mining areas is very large: mineral exploitation directly destroys the original topography and biological communities in the mining area, resulting in ...
Patients should not be vaccinated against smallpox while on corticosteroid therapy. Otherimmunizationprocedures should not be undertaken in patients who are on corticosteroids, especially on high dose, because of possible hazards of neurological complications and a lack of antibody response. ...
