We demonstrate for first time that ultrasound exposure at therapeutic frequency in continuous or pulsed mode, is able to reduce hepatic injury in the setting of partial hepatectomy with vascular exclusion. Importantly, this study enlightened that therapy based on pulsed ultrasonography at 0. 8 MHz…
A new kind of supervised learning approachis proposed to determine the number of occupants in aroom in order to use these estimate for improved energymanagement. It introduces the concept of Parametrizedclassifier. It relies on the predetermined structure ofsupervised learning classifiers, where any classifier couldbe used…
Abstract The existence ofsecond-order structural phase transition in the SnSe at a pressure of10GPa has been proved theoretically. The calculation is performed using the plane-wave pseudopotential approach to density-functional theory within the local-density approximation (LDA) withthe help ofthe ABINIT software package. Theabrupt change inbulk module…
