Data-driven polarimetric imaging: a review

This study reviews the recent advances in data-driven polarimetric imaging technologies based on a wide range of practical applications.The widespread international research and activity in polarimetric imaging techniques demonstrate their broad applications and interest.Polarization information is increasingly incorporated into convolutional neural networks(CNN)as a supplemental feature of objects to improve performance in computer vision task applications.Polarimetric imaging and deep learning can extract abundant information to address various challenges.Therefore,this article briefly reviews recent developments in data-driven polarimetric imaging,including polarimetric descattering,3D imaging,reflection removal,target detection,and biomedical imaging.Furthermore,we synthetically analyze the input,datasets,and loss functions and list the existing datasets and loss functions with an evaluation of their advantages and disadvantages.We also highlight the significance of data-driven polarimetric imaging in future research and development.

Bioinformatic analysis and in vivo validation of angiogenesis related genes in inflammatory bowel disease

Angiogenesis plays a significant role in the occurrence and development of inflammatory bowel disease(IBD).The aim of this study is to explore potential angiogenesis related genes(ARGs)in IBD through bioinformatics analysis and in vivo experiments.Methods:GSE57945,GSE87466,and GSE36807 were obtained from the Gene Expression Omnibus database.GSE57945 was used as the training set,while GSE87466 and GSE36807 were used as the validation set.The key ARGs associated with IBD were identified using the least absolute shrinkage and selection operator(LASSO)and random forest methods.These identified ARGs were then utilized to construct a diagnostic model for IBD.The Single-Sample Genome Enrichment Analysis,Cibersort,and Xcell methods were used to evaluate the immune infiltration.Expression of amyloid beta precursor protein(APP)was verified in the IBD mouse model induced by dextran sulfate sodium using immunohistochemistry(IHC).Results:The receiver operating curve area of GSE57945 was 0.948.Two distinct clusters were identified using consensus clustering and non-negative matrix factorization clustering.Subsequent analyses revealed significant differences in immune levels and functional enrichment between the two clusters.The successful construction of the animal model for the IBD was evident by hematoxylin and eosin staining,while IHC results showed a high expression of APP in IBD and a low expression in normal tissues.Conclusion:Our findings provide new insights into the diagnosis of IBD by ARGs,and APP could be a potential novel biomarker for IBD and promising therapeutic targets.

Propagation-based incremental triangulation for multiple views 3D reconstruction

To balance the accuracy and efficiency in multiple-view triangulation with sequential images, a high-efficiency propagationbased incremental triangulation(INT) method, carving three-dimensional(3 D) scene points by updating the incoming feature track one by one without iterations, is proposed. Based on the INT method, a more accurate iteration-limited INT method is also established with few iterations to bound the propagated errors, ensuring the accuracy of subsequent3 D reconstruction. Finally, experimental results demonstrate that the proposed methods can balance the efficiency and accuracy in different multiple-view INT situations.

Age-Specific Pulmonary Tuberculosis Notification Rates—China,2008–2018

What is already known about this topic?The incidence of tuberculosis(TB)was declining in China but has plateaued in recent years.What is added by this report?Notifications of pulmonary TB declined by 27.7%between 2008 and 2018,with an average crude decline of 3.4%per year and an average age-adjusted decline of 4.3%per year.Notifications decreased faster among older people,but slower in western China;the combination of trends led to an inflection in 2016 in the overall notification trend from decreasing to stable.What are the implications for public health practice?Population ageing and geographic disparities slowed tuberculosis control progress in China.Enhanced,targeted,and proactive responses are recommended to achieve the End TB targets.
