Tests and Measures of the Structure of Matter at Short Distances*
نویسنده
چکیده
Recent progress in gauge field theories has led to a new perspective on the structure of matter and basic interactions at short distances. It is clear that at very high energies quantum electrodynamics, together with the weak and strong interactions, are part of a unified theory with new fundamental constants, new symmetries, and new conservation laws. A nontechnical introduction to these topics is given, with emphasis on fundamental tests and measurements.

Investigation of electron correlation effects in armchair silicene nanoribbons
In this study, the electronic structure of armchair silicene nanoribbons (ASiNRs) is investigated for various widths using first-principle calculations and the framework of the density functional theory. Electronic structure of ASiNRs shows a direct band gap which is decreased with increasing the nanoribbon's width, showing an oscillatory behavior. The effective Coulomb interaction between loca...

متن کاملInvestigating the Relatedness of Cloze-Elide Test, Multiple-Choice Cloze Test, and C-test as Measures of Reading Comprehension
Reading comprehension ability consists of multiple cognitive processes, and cloze tests have long been claimed to measure this ability as a whole. However, since the introduction of cloze test, different varieties of it have been proposed by the testers. Thus, the present study was an attempt to examine the relatedness of Cloze-Elide test, Multiple-choice (MC) cloze test, and C-test as three di...
متن کاملThe relationship between working memory and L2 reading comprehension
Since an important role for working memory has been found in the first language acquisition (e.g., Daneman, 1991; Daneman & Green, 1986; Waters & Caplan, 1996), research on the role of working memory is emerging as an area of concern for second language acquisition (e.g., Atkins & Baddeley, 1998; Miyake & Freidman, 1998; Robinson, 1995, 2002, ...
