Photoplethysmography (PPG) is a ubiquitous physiological measurement that detects beat-to-beat pulsatile blood volume changes and hence has potential for monitoring cardiovascular conditions, particularly in ambulatory settings. A PPG dataset created particular use case often imbalanced, due to low prevalence of the pathological condition it targets predict paroxysmal nature as well. To tackle this problem, we propose log-spectral matching GAN (LSM-GAN), generative model can be used data...
Photoplethysmography (PPG) monitoring has been implemented in many portable and wearable devices we use daily for health fitness tracking. Its simplicity cost-effectiveness enabled a variety of biomedical applications, such as continuous long-term heart arrhythmias, fitness, sleep tracking, hydration monitoring. One major issue that can hinder PPG-based applications is movement artifacts, which lead to false interpretations. In implementations, noisy PPG signals are discarded. Misinterpreted...
Stress is becoming an increasingly prevalent health issue, seriously affecting people and putting their lives at risk. Frustration, nervousness, anxiety are the symptoms of stress these common (40%) in younger people. It creates a negative impact on human damages performance each individual. Early prediction level can help to reduce its different serious issues related this mental state. For this, automated systems required so they accurately predict levels. This study proposed approach that...
Abstract Objective . Prompt identification and recognization of myocardial ischemia/infarction (MI) is the most important goal in management acute coronary syndrome. The 12-lead electrocardiogram (ECG) widely used as initial screening tool for patients with chest pain but its diagnostic accuracy remains limited. There early evidence that machine learning (ML) algorithms applied to ECG waveforms can improve performance. Most studies are designed classify MI from healthy controls thus limited...

Smartwatches and other wearable devices are equipped with photoplethysmography (PPG) sensors for monitoring heart rate aspects of cardiovascular health. However, PPG signals collected from such susceptible to corruption noise motion artifacts, resulting in inaccuracies during estimation. Conventional denoising methods filter or reconstruct ways that eliminate morphological information, even the clean segments signal should ideally be preserved. In this work, we develop an algorithm...
Bacterial identification is of great importance in clinical diagnosis, environmental monitoring, and food safety control. Among various strategies, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has drawn significant interest been clinically used. Nevertheless, current bioinformatics solutions use spectral libraries for the bacterial strains. Spectral library generation requires acquisition MALDI-TOF spectra from monoculture colonies, which...
