this study investigates the effect of different types of subtitle on incidental vocabulary learning among iranian efl learners. to this end, 60 high school students in behbahan were selected after taking a proficiency test. the test was administered to ensure participants' homogeneity. participants were randomly assigned to three experimental groups, namely, bimodal group (a), standard gro...
Irritation and negative valence are closely associated in perception. However, these perceptual aspects can be dissociated in olfaction where irritation can accompany both pleasant and unpleasant odorants. Whereas the sensation of odor reflects transduction at olfactory receptors, irritation reflects concurrent transduction of the odorant at trigeminal receptors. Thus a stimulus can be either a...
We present an overview of the bimodal amplitude-frequency-modulation (AM-FM) imaging mode of atomic force microscopy (AFM), whereby the fundamental eigenmode is driven by using the amplitude-modulation technique (AM-AFM) while a higher eigenmode is driven by using either the constant-excitation or the constant-amplitude variant of the frequency-modulation (FM-AFM) technique. We also offer a com...
We report in this work the formation of fluorescence and MRI bimodal imaging nanoparticles achieved by electrostatic self-assembly. The nanoparticles are micelles formed with Gd(3+) ion, a bisligand that contains aggregation induced emission (AIE) group, and a block copolymer. The coordination between the Gd(3+) ion and the bisligand produces a negatively charged coordination complex, which int...
In this communication, a novel synthetic pathway has been applied to prepare a dual imaging agent in a single molecule. The dinuclear Re(I)/Tc(I) complex 6, namely [Re(CO)(3)(bipy){(4-PyrIDA)Tc(CO)(3)}], is the first example of a Re/Tc-based heterometallic assembly which could act as a potential bimodal Optical/SPECT probe. Interestingly, the Re(I) complex intermediate 4 exhibits significant ph...
Myocardial haemorrhage after acute reperfused ST-elevation myocardial infarction evolves progressively and contributes to the early bimodal pattern in T2-relaxation time: advanced imaging and clinical significance David Carrick, Caroline Haig, Nadeem Ahmed, Samuli M Rauhalammi, Guillaume Clerfond, jaclyn carberry, Ify Mordi, Margaret McEntegart, Mark Petrie, Hany Eteiba, Stuart Hood, Stuart Wat...
BACKGROUND AND PURPOSE Dynamic contrast-enhanced T1-weighted perfusion MR imaging is much less susceptible to artifacts, and its high spatial resolution allows accurate characterization of the vascular microenvironment of the lesion. The purpose of this study was to test the predictive value of the initial and final area under the time signal-intensity curves ratio derived from dynamic contrast...
