The group IV Ge–Sn system is a promising candidate for variety of electronic and photonic applications due to its tunable bandgap compatibility with Si-based technology. However, the peculiarities components interaction, phases evolution and, especially, their thermal stability are still far from brimming comprehension. In course in situ TEM heating experiments, we demonstrate high potential us...

Using three cluster model, the ternary fission of (_"98" ^"252" )Cf is studied. We applied collinear and equatorial configurations to study the ternary fission of (_"98" ^"252" )Cf when three fragments are Sn, Ni and Ca. The potential energy of collinear and equatorial configurations is calculated. We calculated the potential energy for odd and even values of A3. Also, we compared the potential...

Eight bis(salicylaldiminato)tin(II) complexes have been synthesized from the reaction of Sn[N(SiMe(3))(2)](2) and 2 equiv of the corresponding ligands at room temperature. The ligands, synthesized from salicylaldehyde and amines, were designed to have different electronic and steric properties using different amines to synthesize the tin(II) complexes as aniline (2a), 2,6-dimethylaniline (2b), ...

در این کار، ما کاتالیست pt-sn/graphene را برای اکسیداسیون اتانول در محیط اسیدی، گزارش کرده ایم. گرافن، با استفاده از محلول مایع یونی و لایه برداری الکتروشیمیایی الکترودهای گرافیت سنتز شد. سپس کاتالیست های pt-sn بر پایه گرافن به وسیله اتیلن گلیکول، که به عنوان عامل تثبیت کننده استفاده می شود، احیا شدند تا نانو ذرات ptsn با پخش شدگی بالا بر روی صفحات گرافن تهیه شوند و در اکسیداسیون اتانول در پیل ...

Let Sn = 1 nXnX∗ n where Xn = {Xij } is a p × n matrix with i.i.d. complex standardized entries having finite fourth moments. Let Yn(t1, t2, σ ) = √ p(xn(t1)∗(Sn + σI)−1xn(t2)− xn(t1)∗xn(t2)mn(σ )) in which σ > 0 and mn(σ)= ∫ dFyn (x) x+σ where Fyn(x) is the Marčenko–Pastur law with parameter yn = p/n; which converges to a positive constant as n→∞, and xn(t1) and xn(t2) are unit vectors in Cp ,...

We have started this class by studying the representation theory of the symmetric group Sn over the complex numbers. We finish by giving a brief introduction to the representation theory of Sn over a field F of positive characteristic p. We will also establish a connection between the representations of ŝlp and those of FSn. This connection was one of motivations to consider Kac-Moody algebra a...

Accurate computational identification of promoters remains a challenge as these key DNA regulatory regions have variable structures composed of functional motifs that provide gene-specific initiation of transcription. In this paper we utilize Convolutional Neural Networks (CNN) to analyze sequence characteristics of prokaryotic and eukaryotic promoters and build their predictive models. We trai...

تحقیق در ساختارهای پوسته و گوشته فوقانی در فلات ایران بسیار محدود بوده و در این زمینه کار اندکی صورت گرفته است. در این مقاله یک هدف اصلی مد نظر قرار دارد و آن به تصویر کشیدن سرعت‌های Pn و Sn در زیر فلات ایران، به منظور آزمایش کردن مدل‌های سه‌بعدی گوشته و به‌دست آوردن روشی جدید و آزمودن آن برای به‌دست آوردن تصحیح زمان‌های سیر Pn و Sn که متشابه سه‌بعدی منحنی‌های زمان سیر مدل‌های یک‌بعدی‌اند. روش ...

Most micro-electro-mechanical systems (MEMS) devices contain fragile moving parts, which poses challenges in process integration of interconnection methods requiring wet-chemistry, such as solid-liquid interdiffusion bonding (SLID). These sensitive MEMS structures can be protected from either the wet-chemistry or plated metals during chemical/electro-chemical plating SLID materials; however, th...

The pink portion of the rabbit harderian gland was found to be a rich source of ATP: I-alkyl-sn-glycerol phosphotransferase. The enzyme, associated with the microsomal fraction of the gland, exhibits a pH optimum of ‘7.1. ATP and Mg2f are absolute requirements for enzymatic activity; the apparent K,,, for Mg2+ATP is 1.6 mM. Manganese partially substituted for Mgz+, but the measured rate in the ...
