With over 2.1 million new cases of breast cancer diagnosed annually, the incidence and mortality rate this disease pose severe global health issues for women. Identifying disease’s influence is only practical way to lessen it immediately. Numerous research works have developed automated methods using different medical imaging identify BC. Still, precision each strategy differs based on available resources, issue’s nature, dataset being used. We proposed a novel deep bottleneck convolutional...

Globally, pests and plant diseases severely threaten forestry agriculture. Plant protection could be substantially enhanced by using non-contact, extremely effective, reasonably priced techniques for identifying tracking across large geographic areas. Precision agriculture is the study of other technologies, such as hyperspectral remote sensing (RS), to increase cultivation instead traditional agricultural methods with less negative environmental effects. In this work, we proposed a novel...

Endoscopic sleeve gastroplasty (ESG) is safe and effective in patients with a body mass index (BMI) more than 30, few cases reported overweight (BMI 27-30). However, evidence lacking the group because procedure not currently performed routinely for such patients. In this study, we aim to evaluate safety efficacy of ESG BMI between 27 30 who failed other weight loss modalities and/or had weight-related comorbidities.This was subgroup analysis data pertaining adults underwent as primary...
