“…To compose the dataset, in addition to image features (Section 3.2), we also used the demographic data of patients' age and sex (Table 1) available in the CMRI exam metada. Bergamasco et al [2022] presented more details about the CMRI exams used, such as imaging specifications and the distribution of cases by age and sex.…”

“…Segmentation (Subprocess A). Bergamasco et al [2022] performed the segmentation of the LV ventricular wall applying a semi-automatic method to identify the contours of the endocardium and epicardium (outermost layer of the pericardium), using the Medviso Segment software [Heiberg et al 2010]. In Figure 2, we present examples of regions of interest from CMRI slices highlighting a NA case (Figure 2a), a DC case (Figure 2b), and a HC case (Figure 2c).…”

Cardiomyopathies are diseases usually characterized by dilation or hypertrophy of the heart muscle. Left Ventricle (LV) is the heart chamber most affected in most cases. Cardiac Cine Magnetic Resonance Imaging (CMRI) is a powerful tool applied for diagnosis of cardiomyopathies. Although some studies define descriptors based on CMRI images, usually they are related to clinical metrics. In this paper, we explored shape and motion features from the LV ventricular wall to define descriptors based on a priori knowledge about heart anomalies to build Supervised Machine Learning-based classification models capable of discriminating cases of dilated cardiomyopathy, hypertrophic cardiomyopathy, or those ones without anomalies associated with these diseases. The best classification model built and evaluated achieved F1-score = 0.85± 0.05, accuracy = 0.85± 0.04, and AUC = 0.94± 0.02. Our results are promising, indicating the potential of the approach for applications in computer-aided diagnosis systems.

“…There are unlimited number of applications for bipartite graph such as search engines, social networks [18], and recommendation systems [19], data and networks classification [20], [21], cloud computing [22], health care, biology and medicine [23]. Other applications relevant to bipartite graphs are related to x-ray crystallography, metabolic pathways, chemical reaction networks, missile guidance, routing and wavelength assignment problem, and metabolic pathways [24], [25],…”

Designing a logic circuit from the scratch requires its description in logical expression, (e.g. sum of products), and then the expression should be optimized to diminish the cost and complexity of the circuit by reducing the number of literals, the number of logical terms, and/or logical operations. Karnaugh map, K-Map, is the most popular method in the optimization process, but it suffers from many drawbacks such as its inefficiency or the inability to be used in minimizing logical expression containing more than four literals, in addition to the complexity of implementing it as a program. In this paper, we propose a new algorithm to optimize the logic circuits depending on the bipartite graph and some of the suggested mathematical operations. The proposed algorithm is simple for programming implementation, literal-unlimited number, and is easy to be visualized and understandable. Many of the logic circuits of 3, 4, 5, and 6 literals were optimized and the results were correctly matched with the results of the Karnaugh map. Also, tens of logic circuits of more than 6 literals are optimized and the results were correctly checked with their truth tables and Logic-Friday tool.
