Recent confirmation of dicamba-resistant kochia [Bassia scoparia (L.) A.J. Scott] in Alberta warrants investigation resistance to other commonly used synthetic auxin herbicides like fluroxypyr. A randomized-stratified survey 305 sites was conducted 2017 determine the status fluroxypyr-resistant kochia. Overall, 13% populations were fluroxypyr-resistant. Only 4% both fluroxypyr- and dicamba-resi...
the importance of amaranthus retroflexus pollen in causing respiratory allergy has been well ascertained in many countries including iran with a high positive rate (69%) among iranian allergic patients. the aim of the present study is to identify the allergenic properties of a. retroflexus pollen. sixteen patients with allergy to a. retroflexus pollen were selected for the study. the antigenic ...
By performing a stochastic dynamic in a space of Slater determinants, the full configuration interaction quantum Monte Carlo (FCIQMC) method has been able to obtain energies which are essentially free from systematic error to the basis set correlation energy, within small and systematically improvable error bars. However, the weakly exponential scaling with basis size makes converging the energ...
Small soluble oligomers, and dimers in particular, of the amyloid β-peptide (Aβ) are believed to play an important pathological role in Alzheimer's disease. Here, we investigate the spontaneous dimerization of Aβ42, with 42 residues, by implicit solvent all-atom Monte Carlo simulations, for the wild-type peptide and the mutants F20E, E22G and E22G/I31E. The observed dimers of these variants sha...
Gibbs ensemble Monte Carlo simulations were used to test the ability of intermolecular pair potentials derived ab initio from quantum mechanical principles, enhanced by Axilrod-Teller triple-dipole interactions, to predict the vapor-liquid phase equilibria of pure neon, pure argon, and the binary mixtures neon-argon and argon-krypton. The interaction potentials for Ne-Ne, Ar-Ar, Kr-Kr, and Ne-A...
In this paper, we describe the way to set up the floppy-box Monte Carlo (FBMC) method [L. Filion, M. Marechal, B. van Oorschot, D. Pelt, F. Smallenburg, and M. Dijkstra, Phys. Rev. Lett. 103, 188302 (2009)] to predict crystal-structure candidates for colloidal particles. The algorithm is explained in detail to ensure that it can be straightforwardly implemented on the basis of this text. The ha...
Proliferation of herbicide-resistant weeds demands re-evaluation fundamental weed control objectives. Yield loss mitigation remains a priority, but limiting seed return (WSR) to the soil seedbank is key preventing annual from multiplying. The critical period for (CPWSC) growing season during which can minimise production. CPWSC provides framework limit WSR by targeting phenological stages devel...
To investigate conformational properties of an isolated n-octadecane chain solvated in water-acetonitrile mixtures, configurational-bias Monte Carlo simulations in the isobaric-isothermal ensemble were performed at T = 323 K and p = 10 atm. The united-atom version of the transferable potentials for phase equilibria force field was used to represent n-octadecane and acetonitrile, and the TIP-4P ...
RNA secondary structure folding kinetics is known to be important for the biological function of certain processes, such as the hok/sok system in E. coli. Although linear algebra provides an exact computational solution of secondary structure folding kinetics with respect to the Turner energy model for tiny ([Formula: see text]20 nt) RNA sequences, the folding kinetics for larger sequences can ...
