چکیده
In recent years, a number of achiral liquid crystal dimer molecules have been shown to exhibit nematic–nematic phase transitions. The lower temperature has identified as the NTB phase, which demonstrates emergent chirality in spontaneous formation heliconical structure. Recent fully atomistic simulations molecule CB7CB (1,7-bis-4-(4′-cyanobiphenyl) heptane), with an odd carbon spacers between mesogenic parts molecule, captured NTB–N–I sequence, providing picture order at molecular level. this paper, we use develop coarse-grained model using systematic coarse graining phase. We both force matching (in form MS-CG method) and iterative Boltzmann inversion (IBI) methodologies. Both techniques capture within Moreover, developed via is provide excellent representation simulation reference and, remarkably, good transferability across temperatures, allowing NTB–N N–I transitions be simulated. also compare results those Martini 3-based model.

Local distortion energy and coarse-grained elasticity of the twist-bend nematic phase.
The recently discovered twist-bend nematic phase of achiral bent-shaped molecules, NTB, has a doubly degenerate ground-state with a periodically modulated heliconical structure and unusual distortion elasticity, the theoretical description of which is still debated. We show that the NTB phase has the same macroscopic symmetry as another periodic mesophase, the chiral smectic-A, SmA*. Based on t...

در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...
15 صفحه اولwuthering heights and the concept of marality/a sociological study of the novel
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
