this study is an attempt tofind the effect of four types of feedback(direct,underline,code,translation)on the writing performance of iranian learners ofjapanese as a foreign language.in this research,we have tried to suggest new ways of correcting students’writing through giving different kinds of feedback in the process of learning to write.the study focused on the accuracy of using prepositio...

In this study we present a detailed, mechanism-based mathematical framework of Drosophila circadian rhythms. This framework facilitates a more systematic approach to understanding circadian rhythms using a comprehensive representation of the network underlying this phenomenon. The possible mechanisms underlying the cytoplasmic "interval timer" created by PERIOD-TIMELESS association are investig...

OBJECTIVE To assess the effects of electronic health record-based clinical decision support (CDS) and physician performance feedback on adherence to guidelines for acute otitis media (AOM) and otitis media with effusion (OME). METHODS We conducted a factorial-design cluster randomized trial with primary care practices (n = 24) as the unit of randomization and visits as the unit of analysis. B...

Abstract The extent to which teachers’ written corrective feedback (WCF) is conducive to ESL learners’ improvement has been discussed since Truscott’s claim in 1996. The mentioned debate continues because there has been lots of contrastive research studies with different results. This paper presents the results of a 2-month study of the effectiveness of WCF to 65 low intermediate Iranian learne...

We present a comprehensive study of the emission dynamics of semiconductor lasers induced by delayed optical feedback from a short external cavity. Our analysis includes experiments, numerical modeling, and bifurcation analysis by means of computing unstable manifolds. This provides a unique overview and a detailed insight into the dynamics of this technologically important system and into the ...

Trajectory tracking of uncertain time-delay linear systems by output feedback control is of theoretical importance and practical value. In this paper, concentrating on a class of linear plants whose relative degree equals to system dimension, we develop a Lyapunov-based control scheme to achieve trajectory tracking despite some classic difficulties including unmeasurable system state, unknown p...

This contribution represents the first comprehensive attempt to treat complex geometry configurations of the scanning electrochemical microscope (SECM) using the alternating direction implicit finite difference method (ADIFDM). Specifically, ADIFDM is used to simulate the steady-state as well as the transient (chronoamperometric) behavior of a hemispherical ultramicroelectrode (UME) tip of the ...

We present a comprehensive report of our work in the design and implementation of systems that combine holog-raphy with haptic feedback. Two separate holo-haptic systems are described. First, we describe a static system wherein a user can see a free-standing static holographic image and inspect its shape using a force-feedback stylus. In the second system, visual display is provided by a dynami...
