Perhaps no ancient Greek practice is more opaque to us than the Athenian institution of ostracism. Scholars have repeatedly labeled it bizarre, intrin sically paradoxical, and exotic. If we follow Darnton’s exhortation (1984: 5), however, our puzzlement is not a cause for dismay, but a signal of fertile territory for the acquisition of a new perspective on the ancient Greek past. In many ways,...

Neuropilin-1 (NRP1) has been identified as a VEGF-A receptor. DJM-1, a human skin cancer cell line, expresses endogenous VEGF-A and NRP1. In the present study, the RNA interference of VEGF-A or NRP1 suppressed DJM-1 cell proliferation. Furthermore, the overexpression of the NRP1 wild type restored shNRP1-treated DJM-1 cell proliferation, whereasNRP1 cytoplasmic deletionmutants did not. A co-imm...
Telomeres maintain the integrity of linear chromosomes by preventing the unsolicited recruitment of DNA repair machineries to chromosome ends (de Lange, 2009; Dehé and Cooper, 2010; Jain and Cooper, 2010) and engaging telomerase to solve the end replication problem (Greider and Blackburn, 1985; Artandi and Cooper, 2009). At a distinct site on the chromosome, centromeres mediate the attachment o...
CRYSCOR is a periodic post-Hartree–Fock program based on local functions in direct space, i.e., Wannier functions and projected atomic orbitals. It uses atom centered Gaussians as basis functions. The Hartree–Fock reference, as well as symmetry information, is provided by the CRYSTAL program. CRYSCOR presently features an efficient and parallel implementation of periodic local second order Møll...

تاکنون روش‌های متعددی برای کمینه‌کردن تغییر شکل‌های جوش و تنش‌های پسماند آن ارائه شده است. یک روش عملی و ساده که می‌تواند سبب کاهش تنش‌های پسماند جوش شود، استفاده از سیم‌های جوش با دمای پایین است. به این صورت که تغییر ماهیت مواد پرکننده می‌تواند سبب تغییر متالورژیکی در ناحیة جوش و منطقة تحت تأثیر جوش و درپی آن افزایش تنش‌های پسماند انقباضی روی خط جوش گردد. بنابراین با ایجاد ترکیبات شیمیایی مناس...
Correct spindle position is an essential feature of cell division from yeast to man. In animal cells, the cleavage furrow is specified so as to bisect the mitotic spindle. Therefore, correct orientation of the spindle along a given axis, as well as its accurate placement on this axis (hereafter collectively referred to as “spindle positioning” for simplicity), is critical for dictating the rela...
