dear editor computer is one of the fundamental tools in applying most electronically-based teaching methods. many studies on the students of university of medical sciences have been focused on their computer and internet skill levels. the skill levels in using computers and internet in isfahan university of medical sciences (iums) were estimated 14.87 and 12 (from 20), respectively (1) and this...

In view of native/nonnative language teacher dichotomy, different characteristics have been assigned to these 2 groups. The dichotomy has been the source of different actions and measures to clarify the positive and negative points of being (non)native teachers. In recent years, many researchers have revisited this dichotomy. The challenge to the dichotomy can be a source of motivation to explo...

Metallic nanowires show unique physical properties owing to their one-dimensional nature. Many of these unique properties are intimately related to electron-electron interactions, which have a much more prominent role in one dimension than in two or three dimensions. Here we report the direct visualization of quantum size effects responsible for preferred lengths of self-assembled metallic irid...

While computers are known to facilitate lower levels of learning, such as rote memorization of facts, measurable through electronically administered and graded multiple-choice questions, yes/no, and true/false answers, the imparting and measurement of higher-level cognitive skills is more vexing. These require more open-ended delivery and answers, and may be more problematic in an entirely virt...

Despite the structure and objectivity provided by the Gene Ontology (GO), the annotation of proteins is a complex task that is subject to errors and inconsistencies. Electronically inferred annotations in particular are widely considered unreliable. However, given that manual curation of all GO annotations is unfeasible, it is imperative to improve the quality of electronically inferred annotat...

As the quantity of electronically generated engineering data grows rapidly, building computer systems to analyze data automatically and intelligently becomes increasingly important to engineers. The overall process of extracting useable knowledge from electronically stored data is called knowledge discovery in databases. The part of the process where patterns are extracted or models are built i...
