this study investigated the relative effects of deductive and inductive form-focused instruction (ffi) on the acquisition of 4 non-generic definite article uses(cultural, situational, structural, and textual) as assessed by explicit and implicit outcome measures. the tests utilized to assess efl learners' acquisition of definite article uses were timed and untimed grammaticality judgment tests....

Complex data structures such as lists and trees are di cult to implement in C in a way that programmers have little or no di culties to maintain and reuse the source code. Thus, converting such data structures into instances of generic C++ components to increase the maintainability of the code is a reasonable task. Replacing data structures with instances of generic data structures is a non-tri...

This paper introduces an intermediate grouping phase whereby structures, meant to correspond to generic 3D junctions of planar and curved surfaces, are extracted from imperfect basic constant curvature contour primitives. This research work is part of a more generic project for detecting and describing generic high-level structures corresponding to 3D objects and/or parts of 3D objects in a sin...

Abstract Abstract Background: Availability and affordability of medicines are crucial to achieving success in prevention programs, particularly in developing countries. Objective: The aim of this study was to determine the availability and affordability of cardiovascular medicines for secondary prevention in Tehran province of Iran. Methods: A cross-sectional survey was conducted in Tehran pro...

We study the perturbation theory of structured matrices under structured rank one perturbations, and then focus on several classes of complex matrices. Generic Jordan structures of perturbed matrices are identified. It is shown that the perturbation behavior of the Jordan structures in the case of singular J-Hamiltonian matrices is substantially different from the corresponding theory for unstr...
