The stabilizer code is the most general algebraic construction of quantum error-correcting codes proposed so far. A stabilizer code can be constructed from a self-orthogonal subspace of a symplectic space over a finite field. We propose a construction method of such a selforthogonal space using an algebraic curve. By using the proposed method we construct an asymptotically good sequence of bina...
In recent years, because of the advantage of radiation technology-low energy, clean, environmental protection, etc., so that the use of radiation technology for polymer synthesis or processing research continues to heat up; however polymer materials irradiated via high-energy radiation prone to produce free group or to react with atomic oxygen in the air, resulting in the material cracking, cro...
The purpose of this study was to investigate the stability of lysozyme in aqueous solutions in the presence of various extremolytes (betaine, hydroxyectoine, trehalose, ectoine, and firoin) under different stress conditions. The stability of lysozyme was determined by Nile red Fluorescence Spectroscopy and a bioactivity assay. During heat shock (10 min at 70°C), betaine, trehalose, ectoin and f...
تاثیر پارامترهای فرآیند کشش و نیز تاثیر فرآیند تثبیت حرارتی بر خصوصیات مکانیکی نخ های پلی پروپیلن مورد بررسی قرار گرفت. نشان داده شده است که با افزایش نسبت کشش استحکام و مدول بهبود قابل ملاحظه ای می یابند و کار تا حد پارگی و ازدیاد طول نخ کاهش می یابد. تثبیت حرارتی انجام گرفته بر خصوصیات مکانیکی تاثیر گذار است، به نحوی که موجب افزایش استحکام نخ می شود و کار تا حد پارگی و ازدیاد طول نخ بر اثر تث...
Pancreas cancer cells escape most treatment options. Heat shock protein (Hsp)90 is frequently over-expressed in pancreas carcinomas and protects a number of cell-cycle regulators such as the proto-oncogene Cdc25A. We show that inhibition of Hsp90 with geldanamycin (GD) destabilizes Cdc25A independent of Chk1/2, whereas the standard drug for pancreas carcinoma treatment, gemcitabine (GEM), cause...
We show the equivalence of two approaches to the design of entanglement distillation protocols. The first approach is based on local unitary operations that yield permutations of tensor products of Bell states. The second approach is based on stabilizer codes.
Group Operations Definition. Let G be a group and S a set. An operation of G on S is a rule for combining elements g ∈ G and s ∈ S so that gs ∈ S, such that 1s = s for all s, and (gg’)s = g(g’s) for all g, g’, and s. With this operation, S is called a G-set. Definition. Let s ∈ S, with S a G-set. The orbit of s is the set Os = {s’ ∈ S | s’ = gs for some g ∈ G}. Proposition. S is a union of disj...
We study the nucleation and propagation of the normal zone in large composite superconductors, considering the relatively long time of current redistribution in the stabilizer. We propose a model treating the composite as an effective electrical circuit, which yields two diffusion equations for the electric current and temperature distributions along the conductor. Numerical simulations are per...
We prove that if X is a meromorphic subvariety of a commutative meromorphic group G and X has finite stabilizer, then X is contained in a translate of an algebraic subgroup of G. We give an application with a “diophantine” flavour.
This paper examines the first-best fiscal policy in a stochastic, infinite-horizon representative agent model that exhibits consumption-enhanced as well as wealth-enhanced social status in the household utility. We show that the first-best labor tax rate is a positive constant that is used to correct negative consumption externalities. The first-best capital tax rate is also positive in order t...
