Dynamical Heterogeneity and Jamming in Glass-Forming Liquids†
The relationship between spatially heterogeneous dynamics (SHD) and jamming is studied in a glass-forming binary Lennard-Jones system via molecular dynamics simulations. It has been suggested [Phys. ReV. Lett. 2001, 86, 111]1 that the probability distribution of interparticle forces P(F) develops a peak at the glass transition temperature Tg and that the large force inhomogeneities, responsible...
متن کاملheterogeneity within the orientalist discourse: representation of the orient in womens travelogues and mens paintings
from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...

متن کاملOverlap fluctuations in glass-forming liquids.
We analyze numerically thermal fluctuations of the static overlap between equilibrium configurations in a glass-forming liquid approaching the glass transition. We find that the emergence of slow dynamics near the onset temperature correlates with the development of non-Gaussian probability distributions of overlap fluctuations, measured using both annealed and quenched definitions. Below a cri...
متن کاملthe translators agency and ideological manipulation in translation: the case of political texts in translation classes in iran
در این تحقیق به نقش واسطه ای مترجم در ایجاد تغییرات ایدئولوژیک در ترجمه متون سیاسی پرداخته شده است. بدین منظور محقق متنی سیاسی در خصوص ادعاهای آمریکا در مورد برنامه هسته ای ایران را انتخاب کرد. این متن از سایت spacewar.com انتخاب شد که دارای ایدئولوژی مغرضانه در مورد برنامه هسته ای ایران است. سپس یک گروه 30 نفره از دانشجویان کارشناسی ارشدرشته مترجمی زبان انگلیسی دانشگاه شیخ بهایی انتخاب شدند. ا...
