We have synthesized a set of double-labeled fluorescent probes and evaluated the performance of these fluorescent probes in sequencing by ligation (SBL). The results indicated that the ligation efficiency and specificity of double-labeled fluorescent probes was as higher as that of singe-labeled fluorescent probes. Moreover, double-labeled f luorescent p robes y ielded a r emarkable i ncrease i...
We show that in elementary analysis (EL) the contrapositive of countable choice (CCC) is equivalent to double negation elimination for Σ2-formulas. By also proving a recursive adaptation of this equivalence in Heyting arithmetic (HA), we give an instance of the conservativity of EL over HA with respect to recursive functions and predicates. As a complement, we prove in HA enriched with the (ext...
ژربرا (gerbera jamesonii l.)یکی از گلهای مهم شاخه بریده در جهان محسوب می شود . پژمردگی ، پیری و کیفیت پایین اجزاء گل موجب کاهش بازار پسندی بسیاری از گلهای شاخه بریده از جمله ژربرا می گردد . این پژوهش به منظور بررسی و ارزیابی تاثیر غلظت های مختلف اسید هیومیک (100، 500و 1000میلی گرم در لیتر) روی کیفیت و دوام عمرگل بریده ژربرا ارقام (dune, double dutch) در یک گلخانه تجاری در پاکدشت اجرا گردید . تع...
A survey of results is presented on relationships between the algebraic systems derived from the approximation spaces induced by information systems and various classes of algebras of relations. Rough relation algebras are presented and it is shown that they form a discriminator variety. A characterisation of the class of representable rough relation algebras is given. The family of closure ope...
The paper discusses some N Q R / N M R studies performed on Y B a C u O superconductors at the University of Zürich. In particular, we review studies performed in Y 2 B a 4 C u 7 0 1 5 by measuring various planar Cu N Q R / N M R parameters: the spin-lattice relaxation time, the Knight shift and the indirect component of the Gaussian contr ibution to the spin-spin relaxation time. The temperatu...
background: Endoscopic access to the biliary system can be difficult in patients with surgically altered anatomy, such as a roux-en-Y reconstruction. double balloon enteroscopy (dbE) is a relatively new procedure that enables access to the small bowel. dbE has recently been advocated as a method for endoscopic retrograde cholangiopancreaticography (ErCP) in patients with surgical reconstruction...
Tyrosine (Y)-recombinases have evolved to deliver mechanistically different reactions on a variety of substrates, but these evolutionary transitions are poorly understood. Among them, integron integrases are hybrid systems recombining single- and double-stranded DNA partners. These reactions are asymmetric and need a replicative resolution pathway, an exception to the canonical second strand ex...
Plastoquinol dibenzyl-32P-phosphate was prepared by reduction of plastoquinone with dibenzyl-32P-phosphonate. Catalytic hydrogenation of the product resulted in the reduction of the polyisoprenoid side chain as well as debenzylation. Substantial reduction was also observed with the use of nuclear magnetic resonance for a number of naturally occurring quinones with conditions recommended for qui...
The bond dissociation energies (BDEs) and radical stabilization energies (RSEs) which result from 166 reactions that lead to carbon-centered radicals of the type ˙CH(2)X, ˙CHXY and ˙CXYZ, where X, Y and Z are any of the fourteen substituents H, F, Cl, NH(2), OH, SH, CH[double bond, length as m-dash]CH(2), C[triple bond, length as m-dash]CH, BH(2), CHO, COOH, CN, CH(3), and CF(3), were calculate...
Measurement of the double-differential inclusive jet cross section in proton–proton collisions at √ s = 13 TeV Abstract A measurement of the double-differential inclusive jet cross section as a function of jet transverse momentum p T and absolute jet rapidity |y| is presented. The analysis is based on proton–proton collisions collected by the CMS experiment at the LHC at a centre-of-mass energy...
