title: BengaliVQA : A Benchmark Dataset for Bengali Visual Question Answering

description: The Balanced Bengali VQA dataset consists of 3,280 images paired with 13,046 human-annotated yes/no questions and answers. The dataset is balanced to mitigate linguistic bias, offering a robust resource for Bengali visual question-answering research. This dataset serves as a valuable resource for advancing research in Bengali-language visual question answering.

title: Doutorado MicroRNAa221 e MicroRNA29

description: ABSTRACT 
Profile of microRNA-221 and microRNA-29a in individuals with carotid atherosclerotic disease treated with endarterectomy and carotid angioplasty. Introduction: It is known that microRNAs (miRNA) are involved in the processes of endothelial inflammation and atheroma plaque formation, and are also responsible for regulating its stability, with its expression being specific to each tissue and disease. The miRNA profile can be used as a marker for diagnosis and prognosis and influence the course of diseases, through its stimulation or suppression. Our objective was to study the relationship between the expression of miRNA-221 and 29a in the pre- and postoperative periods of patients with carotid disease, the surgical treatment used and the clinical evolution of this patient. Population and Methods: we selected 61 individuals with unilateral or bilateral carotid stenosis, above 70%, of which 43 underwent endarterectomy (Group 1) and 18 underwent angioplasty (Group 2). We collected blood to measure serum miRNAs preoperatively and 6 months after surgery. In the 1-month postoperative follow-up, we carried out a clinical evaluation and at 6 months, a Carotid Artery Doppler Ultrasound. Results: of the selected patients, the majority were male (62.3%); hypertensive (91.4%); diabetic (52.6%) and with a previous history of smoking (69.2%). Furthermore, 49% of patients were symptomatic and 23.4% reported coronary artery disease. MiRNA-29a showed a statistically significant drop in expression 6 months after surgical correction (95% CI, from 17.83 to 1.20; p&lt;0.001). miRNA-221 behaved in a similar way (95% CI, from 150.99 to 8.67; p&lt;0.001). Regarding the technique used, Group 1 (95% CI, from 1232.5 to 62.6; p &lt; 0.001) showed a greater drop than Group 2 (95% CI, from 847.6 to 47.5; p &lt; 0.001 ). In the ultrasound evaluation, the drop in the group with normal ultrasound at 6 months in miRNA-29a (95% CI, from 20.4 to 1.2; p = 0.001) and miRNA-221 (95% CI, from 153.9 to 9.5; p&lt;0.001) was greater than the drops in the group with restenosis, both in miRNA-29a (95% CI, from 291.1 to 1.2; p=0.04) and in miRNA-221 (IC 95%, from 243.8 to 8.8; p=0.02). We did not observe any interference from the presence of symptoms preoperatively, coronary artery disease or smoking. Conclusion: the drop in the expression of these miRNAs in the postoperative period may suggest the use of these molecules as serum biomarkers for monitoring these patients.

title: Covid-19_Educational_Impact

description: These data come from an online questionnaire survey of 43 teachers and trainers at the Regional Center for Education and Training in the Laayoune Sakia El Hamra region in southern Morocco. They cover several key dimensions linked to the impact of the transition to distance learning during the COVID-19 pandemic. Three files are linked to the data. Firstly, there is a PDF file that includes the questions from the online questionnaire that was used as a data collection tool, this file is entitled "Online Questionnaire's questions". The original data are included in a .CSV file entitled "Impact_COVID-19_Result_dataset". This includes the demographic variables of the individuals. There is also a PDF file containing the keys and descriptions of the dataset symbols, called "Impact_COVID-19_Dataset_Keys".
