The AZO dyes permeability through the blood–brain barrier was found to be a factor in the development of a vast variety of chronic neurological diseases. Because of the potential influence on the environment and human health, the presence of AZO dyes in textile effluents is a major concern. Under visible light, we analyze the photocatalytic degradation of AZO dyes, which are widely utilized in the textile sector. In the present analysis, the properties of combustion-formed mixed sulfide solids were investigated in solutions which are supersaturated simultaneously with dysprosium and erbium. The Sr_1-xCu_xSO₄ nanoparticles arrangement acts as a step for dysprosium and erbium co-doping based on the interactions between thiourea. The phase structure and sample states obtained of the stimulant components be analyzed by Field emission scanning electron microscopy (FESEM), High-resolution transmission electron microscopy (HR-TEM) and photosynthetic studies with X-ray powder diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). Additional data analysis by Rietveld refinement allowed the exposure of a smaller lattice parameter and volume increase related to the absorption of stimulant components. Integrated Sr_1-xCu_xSO₄ co-doped Dy³⁺, Er⁴⁺ showed effective photosynthetic presentation at some stage in decomposition of organic dyes (Acid Black 1, direct blue 15), and hydrogen production from water under ultraviolet light. In addition, Dy, Er co-doped was also deposited and their photosynthetic activities were examined. The consequences and impact on neurology are also examined in this article.</p></div>","PeriodicalId":74295,"journal":{"name":"Neuroscience informatics","volume":"2 3","pages":"Article 100049"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772528622000115/pdfft?md5=cd323689cc252e1ac7b6a5169ead7a24&pid=1-s2.0-S2772528622000115-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49196540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The approach basically combines geometric active contours segmentation with a deep learning-based initialization. As a pre-processing step, an anisotropic filter is used to smooth the image; afterwards, the segmentation process takes place in two phases: the first one is based on the concept of transfer learning, where a pre-trained convolutional neural network coupled with a detector is fine-tuned using a training set of 388 T1-weighted contrast enhanced MRI images that contain a brain tumor (Meningioma); this trained network is able to automatically detect the location of the tumor by generating a bounding box with certain coordinates. The second phase takes place by using the coordinates of the bounding box to initialize the geometric active contour that iteratively evolves towards the tumor's boundaries. While most of the ingredients of this processing chain are more or less well known, the main contribution of this work is in integrating the various techniques in a novel and hopefully clever form, which could take the best of both geometric segmentation algorithms and neural networks, with a relatively light training phase. The performance of such a processing network is evaluated using a separate testing set of 97 MRI images containing the same type of brain tumor.
