Abstract :Smoking is a major cause of various types of cancer,including lung, oral, throat, bladder, kidney, pancreas, andstomach cancer,this smoking-related disease mainly affects the lungs’alveoli, or air sacs, and airways. The toxic compoundsin tobacco smoke affect the respiratory system and causedamage to the airways, leading to a narrowing of theair passages and mucus production. As a result, thelungs become less efficient at transferring oxygen intothe bloodstream, making breathing more difficult. Inadvanced stages, COPD can also affect the heart, leadingto......

Keywords: Cancer, toxic, lung, respiratory, oxygen, bloodstream.

Abstract : The concept of majority domination plays an important role in everyday life. Fundamental concepts and theoretical results related to majority dominating sets have been studied in fuzzy graphs. This research paper extends these ideas by finding fuzzy Majority Domination Number for fuzzy trees and complement of fuzzy graphs.

Keywords: Fuzzy Tree; Complement; Fuzzy Majority Domination Number; Effective Edges; Total Effective Neighborhood Degree.

Abstract : Behaviour of investor plays an important role in shaping portfolio management strategies and investment selections. This study identifies distinct investor clusters based on their behavioural preferences and demographic characteristics. Comprehensive online survey was used to gather empirical data of 325 individual investors across the diverse demographic background. The collected responses were passed through K-means clustering for the segmentation of investors into distinct behavioural personas. Investors were classified according to their risk.....

Abstract : Tuberculosis (also known as TB) and coronavirus (also known as COVID-19) are both contagious diseases that continue to harm millions of individuals all over the world each year. However, their incubation periods are quite different, despite the fact that they share symptoms such as coughing, fever and difficultbreathing. Using a set of nonlinear ordinary....

Abstract : Continuous cardiac monitoring generates large volumes of electrocardiogram (ECG) and related physiological time-series data that provide opportunities for the early detection of anomaly cardiac patterns. However, the temporal dependence, delayed physiological responses, multivariate interactions, non-stationarity, and nonlinear characteristics of cardiac signals present challenges for conventional statistical and anomaly-detection methods. This study developed a Hybrid Lagged Regression Model (HLRM) for modeling continuous cardiac time-series data and detecting...

Abstract : We study the singleton-triple swap graph ST10, whose vertices are the partitions of a ten-element set of type (3,3,3,1), with two vertices adjacent when the singleton is exchanged with one element of a triple block. The graph has 2800 vertices, is 9-regular, and is a 280-fold covering of K10. Its natural transitive S10-action has rank 16. We...
