This paper shows that measurement invariance (defined in terms of an invariant measurement model in different groups) is generally inconsistent with selection invariance (defined in terms of equal sensitivity and specificity across groups). In particular, when a unidimensional measurement instrument is used, and group differences are present in the location but not in the variance of the latent...
The ionizing radiations are able to make either a permanent or temporarily damage in the electronic circuits. The temporary effects during irradiation can be used to detect the ionizing radiation. In this study a diode in reverse bias has been used to investigate the effects of ionization radiation on semiconductors. The variation of reverse current of diode has been monitored due to interactio...
background: the aim of the study was assessment of defaults and conducted meta-analysis of the efficacy of single-dose oral albendazole against t. trichiura infection. methods: we searched pubmed, isi web of science, science direct, the cochrane central register of controlled trials, and who library databases between 1983 and 2014. data from 13 clinical trial articles were used. each article w...
It is vital to accurately estimate the value function in Deep Reinforcement Learning (DRL) such that agent could execute proper actions instead of suboptimal ones. However, existing actor-critic methods suffer more or less from underestimation bias overestimation bias, which negatively affect their performance. In this paper, we reveal a simple but effective principle: correction benefits allev...
Objectives: This study aimed to predict the suicide ideation based on the attentional bias in clinical and non-clinical populations. Methods: Participants were 120 individuals (77 women and 43 men, age range 18-40 years) who were purposively selected and divided into three groups of clinical-suicidal (n=40), clinical non-suicidal (n=40) and non-clinical (n=40). They were measured by Suicide St...
