We study the effects of final state interactions in non-mesonic weak decay $$\varLambda N \rightarrow nN$$ (n is a neutron and either or proton) hypernucleus $$_\varLambda ^4$$ He. Using three-body model distortion interaction emitted nucleon pair with residual nucleus considered. also influence between nucleons using Migdal-Watson model. The effect spin symmetries Based on our calculations, we...

the present study was an attempt to investigate the acquisition of negationproperties by persian monolingual and kurdish-persian bilingual learners of englishacross different levels of language proficiency and within a generative framework.generative models are generally concerned with issues such as universal grammar(ug), language transfer, and morphological variability in nonprimary languaged...

In this paper we propose to predict the students’ outcome by analyzing the interactions that happen in class during the course. PresenceClick lets teachers and students register their interactions during learning sessions in an agile way to give feedback in return about the students’ learning progress by means of visualizations. Some of the registered interactions are the students who are atten...

We discuss new measures in assessing the skill level of students based on their interactions with the Socratic homework tutor, MasteringPhysics. We show that the measurement of the difficulty of problems for a given student as determined by the time to first correct response, the number of incorrect responses without advice, and hints have high reliability (96%). As an immediate application, we...
