Visual inspection of peripheral blood samples is a critical step in the leukemia diagnostic process. Automated solutions based on artificial vision approaches can accelerate this procedure, while also improving accuracy and uniformity of response in telemedicine applications. In this study, we propose a novel GBHSV-Leuk method to segment and classify Acute Lymphoblastic Leukemia (ALL) cancer cells. GBHSV-Leuk is a two staged process. The first stage involves pre-processing, which uses the Gaussian Blurring (GB) technique to blur the noise and reflections in the image. The second stage involves segmentation using the Hue Saturation Value (HSV) technique and morphological operations to differentiate between the foreground and background colors, which improve the accuracy of prediction. The proposed method attains 96.30% accuracy when applied on the private dataset, and 95.41% accuracy when applied on the ALL-IDB1 public dataset. This work would facilitate early detection of ALL cancer.

: This study focuses on the critical task of blood vessel segmentation in medical image analysis, essential for diagnosing cardiovascular diseases and enabling effective treatment planning. Although deep learning architectures often produce very high segmentation results in medical images, coronary computed tomography angiography (CTA) images are more challenging than invasive coronary angiography (ICA) images due to noise and the complexity of vessel structures. : Classical architectures for medical images, such as U-Net, achieve only moderate accuracy, with an average Dice score of 0.

Objective: To construct a visual intelligent recognition model for in Yunnan Province based on the EfficientNet-B4 model, and to evaluate the impact of data augmentation methods and model hyperparameters on the recognition of .
Methods: A total of 400 and 400 snails were collected from Yongsheng County, Yunnan Province in June 2024, and snail images were captured following identification and classification of 300 and 300 snails. A total of 925 images and 1 062 snail images were collected as a dataset and divided into a training set and a validation set at a ratio of 8:2, while 352 images captured from the remaining 100 and 354 images from the remaining 100 snails served as an external test set.

Malignant tumorigenesis is a complex process involving growth, invasion and mechanical deformation of a cancerous tissue. In this paper, a biomechanical model is proposed to couple the mechanical and biological mechanisms governing invasive tumour development. As an example, this model is applied to investigate the spatio-temporal evolution of tissue stresses in an invasive tumour spheroid and its host tissue.

Burning and flaring of oil and gas following the 2010 Deepwater Horizon (DWH) oil spill generated high airborne concentrations of fine particulate matter (PM). Neurological effects of PM have been previously reported, but this relationship has received limited attention in the context of oil spills. We evaluated associations between burning-related PM and prevalence of self-reported neurological symptoms during, and 1-3 years after, the DWH disaster cleanup.

The beauty or ugliness of a face is affected by factors such as the resolution of the face image presented on the screen and its exposure duration. The present study investigated the effects of image resolution and exposure duration on the beauty and ugliness evaluations of face images processed with down-sampling and Gaussian blurring. We prepared two types of face images with these blur processing treatments and conducted two experiments to evaluate beauty and ugliness perceptions at various exposure durations.
