Objective: Trace elements such as manganese (Mn), cobalt (Co) and chromium (Cr) play key roles in metabolic reactions and are important in many physiological enzymatic processes.In this study, we aimed to investigate the acute effects of moderate and strenuous running (treadmill) exercise on the levels of Mn, Co and Cr in the brain, liver, and sple
From STEM-EDXS data to phase separation and quantification using physics-guided NMF
We present the development of a new algorithm which combines state-of-the-art energy-dispersive x-ray (EDX) spectroscopy theory and a suitable machine learning formulation for the hyperspectral unmixing of scanning transmission electron microscope EDX spectrum images.The algorithm is based on non-negative matrix factorization (NMF) incorporating a
Low-cost system for sunlight incidence angle measurement using optical fiber
The development and optimization of renewable energy systems are some of the most necessary topics to advance towards secure and sustainable energy models.Photovoltaic energy is one of those sustainable Sheds options that could contribute to the reduction of greenhouse gas emissions.The optimal angle of solar incidence producing the highest absorpt
Zero-Shot Emotion Detection for Semi-Supervised Sentiment Analysis Using Sentence Transformers and Ensemble Learning
We live in a digitized era where our daily life depends on using online resources.Businesses consider the opinions of their customers, while people rely on the reviews/comments of other users before buying specific products or services.These reviews/comments are usually provided in the non-normative natural language within different contexts and do
