Colorectal polyps are benign lesions that develop in the colon and can progress to cancer if left untreated. Clinical observations from medical images are often preferred over computational results due to the lack of trust in the machine learning models, thereby posing serious challenge for the explainability of the results. In order to computationally diagnose colorectal polyps from cancerous images and explain the results, we propose a Layer-wise eXplainable ResUNet++ (LeXNet++) framework for segmentation of the cancerous images, followed by layer-wise explanation of the results. We utilize a publicly accessible dataset that contains of 612 raw images with a resolution of 256×256×3 and an additional 612 clinically annotated and labeled images with a resolution of 256×256×1, which includes the infected region. The LeXNet++ framework comprises of three components—encoder, decoder and the bridge. The encoder and the decoder components each comprise of four layers. Each of the four layers in the encoder and the decoder comprises of 14 and 11 internal sub-layers, respectively. Among the sub-layers of the encoder and the decoder, there are three 3×3 convolutional layers with an additional 3×3 convolution-transpose layer in the decoder. The output of each of the sub-layers has been explained through heatmap generation after each iteration which have been further explained. The encoder and the decoder are connected by the bridge which comprises of three sub-layers. The results obtained from these three sub-layers have also been explained to inculcate trust in the findings. In this study, we have used three models to segment the images, namely UNet, ResUNet, and proposed LeXNet++. LeXNet++ exhibited the best result among the three models in terms of performance;hence, only LeXNet++ was explained layer-wise. Apart from explanation of the results fetched in this study, the performance of the proposed explainable model has been observed to be 2% greater than the existing poly

Cemented soils are a type of soils whose grains are bonded together due to natural and/or artificial processes. Cementing agents can be natural such as clay, lime, gypsum, or synthesized material like Portland cement. Mechanical behavior of cemented soils under static and cyclic loads is complex due to various characteristics of the cementing agents, the strength of the bonds between the aggregates, and the dilative response of the soil under shearing. The micromechanical behavior of cemented soils can be studied using the Distinct Element Method (DEM). This study aims to evaluate the capability of DEM to analyze the behavior of cemented sand and gravel by simulating a number of three-dimensional consolidated drained triaxial tests under strain-controlled conditions. The outcome of DEM simulations heavily relies on the type of assumed bonded contact model between the particles. In this study, three different bonded contact models—Surface Joint Bond, Parallel Bond, and Linear Bond models—were utilized to simulate specimens cemented with Portland cement, lime, and gypsum. Samples were prepared with three cement contents of 1.5%, 3.0%, and 4.5% and tested under three different confining stresses of 100, 200, and 300 kPa. The investigation focused on shear strength and stress–strain behavior. Test results indicated that gypsum renders the soil most brittle, while Portland cement was identified as the most ductile cementing agent. At lower cement contents and low confining pressures, soil cemented with Portland cement exhibited the highest shear strength. Conversely, within the same cement content range but under higher confining pressures, soil cemented with gypsum displayed the highest shear strength. For higher cement contents, soil cemented with Portland cement exhibited greater shear strength compared to the other two cement types within the tested range of confining pressures. Samples cemented with lime exhibited the lowest peak and ultimate shear strengths. Furthe
