In this article, we describe a novel unsupervised spectral image segmentation algorithm.This algorithm extends the classical Gaussian Mixture Model-based unsupervised classification technique by incorporating a spatial flavor into the model: the spectra are modelized by a mixture of K classes, each with a Gaussian distribution, whose mixing proport
Introduction Adolescent onset substance use is associated with neurodevelopmental, social and psychological harms.Thus, alcohol and other drug prevention programmes are essential to promote health and well-being during this period.Schools are uniquely positioned to deliver such prevention programmes.The last decade has seen a large expansion of sch
Background: Urinary tract infections (UTIs) in women are one of the most prevalent infections occurring at various stages of life.UTI represents one of the most common, challenging and widely misunderstood infectious diseases among women as outpatient and nosocomial infections leading to morbidity.Aim: The objective of our study was to determine th
Selenium (Se) is an essential trace element for humans and animals.Its necessity for plants is still under examination.Due to the contradictory nature of Se and its significance, it has received much interest in recent years.Se deficiency can be harmful to humans, yet almost a billion people are deficient.Its deficiency has been associated with can
Sideways THz generation in Mg:LiNbO3 crystal is studied considering Si-prism-lens couplers with different output surface curvatures.A theoretical approach is developed for modeling the angular distributions of THz radiation power inside the crystal, inside the Si coupler and outside in free space.Our calculations show how the imposition of a plano-
