Quantum transport properties of pure and functioned infinite lead-connection region-lead systembased on the zigzag graphene nanoribbon (2-zGNR) have been investigated. In this work the effectof the doping functionalization on the quantum transport of the 2-zGNR has been computationallystudied. Also, the effect of the imposed gate voltages (-3.0, 0.0 and +3.0 V) and bias voltages 0.0 to2.0 V hav...

objectives: new cognitive theories of delusions have proposed that deficit or bias in inference stage (a stage of normal belief formation) is significant in delusion formation. the aim of this study was predicting the severity of delusions based on jumping-to-conclusion bias in patients with schizophrenia. methods: the sample consisted of 60 deluded patients with schizophrenia who were selected...

bootstrapping the dea is one of the current methods of measuring robust efficiency by constructing a confidence interval and measuring the noise (bias) in production. in this study, two estimators: the conventional data envelopment analysis (dea) and bootstrap simulation with 2,000 bootstrap iterations were applied on a cross sectional data of 296 broiler farms in peninsular malaysia. the objec...

while many international organisations have independent evaluations, including the international monetary fund (imf) and world health organization (who), uniquely the world bank in its 2015 world development report sought to ascertain the potential biases that influence how its staff interpret evidence and influence policy. here, we describe the world bank’s study design, including experiments ...

aim: the purpose of this study was to compare the attention bias about tempting incentives related to opium materials in treated, addicted and normal people. duration of consumption and treating were also considered. method: in this causal-comparative study population was all addicted people who were referred to the rehabilitation offices, addiction treatment clinic, rebirthing centers and narc...

It is hard to believe that as recently as a decade ago, some of us were finding it virtually impossible to get an epidemiologic study funded from the National Cancer Institute if it required collection and analysis of DNA. Now, it is virtually impossible to get anything funded if you do not! The rapid transformation of epidemiology into the molecular world has been so swift and dramatic that by...

Many randomized controlled trials require participants to opt in. Such selfselection could introduce a potential bias, because only the most optimistic may participate. We revisit this prediction. We argue that in many situations, the experimental intervention is competing with alternative interventions participants could conduct themselves outside the experiment. Since participants have a chan...
