there has been a gradual shift of focus from the study of rule systems, which have increasingly been regarded as impoverished, … to the study of systems of principles, which appear to occupy a much more central position in determining the character and variety of possible human languages. there is a set of absolute universals, notions and principles existing in ug which do not vary from one ...

Introduction: Parallel imaging has been widely used in dynamic MRI for improved spatial or temporal resolution. In this study, we propose a new k-t space sampling trajectory for dynamic parallel imaging techniques. This method applies a random phase modulation to the spatial aliasing of images in temporal domain. As a result, the spatial aliasing induced by k-space undersampling at every time f...

a major concern in the last few years has been the fact that the cultural centers are keeping distance with what they have been established for and instead of reproducing the hegemony, they have turned into a place for resistance and reproduction of resistance against hegemony. because the cultural centers, as urban public spaces in the last two decades, have been the subject of ideological dis...

Visual display systems such as the out-the-window or head-down displays of a simulator present a visual scene that is sampled in both the spatial domain (by the display resolution) and the time domain (by the display refresh rate). For a given human visual temporal sensitivity, spatial-frequency content of the scene, and speed of the image motion, spatiotemporal aliasing can occur when the imag...

there is less published research about how teachers in efl contexts respond to students who are relatively less mature and less competent l2 writers. while writing researchers have examined various issues concerning peer and teacher response in writing-oriented classes, little research has centered on the effect of collaborative tasks particularly dictogloss on writing skills. output collaborat...

with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...

Avoiding aliasing in time-resolved flow data obtained through high-fidelity simulations while keeping the computational and storage costs at acceptable levels is often a challenge. Well-established solutions such as increasing sampling rate or low-pass filtering to reduce can be prohibitively expensive for large datasets. This paper provides set of alternative strategies identifying mitigating ...

Object-oriented programming languages allow multiple variables to refer to the same object, a situation known as aliasing. Aliasing is a powerful tool which enables sharing of objects across a system. However, it can cause serious encapsulation breaches if not controlled properly; through aliasing, internal parts of aggregate objects can be exposed and potentially modified by any part of the sy...

this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
