Abstract The interaction of $$\textrm{K}^{-}$$ K - with protons is characterised by the presence several coupled channels, systems like $${\overline{\textrm{K}}}^0$$ ¯ 0 n and $$\upp...
The spectra of octet and decuplet baryons are studied using SU(3) lattice QCD at the quenched level. As an implementation to reduce the statistical fluctuation, we employ the anisotropic lattice with O(a) improved quark action. In relation to Λ(1405), we measure also the mass of the SU(3) flavor-singlet negative-parity baryon, which is described as a three quark state in the quenched lattice QC...

We examine the role of the Λ(1405) in kaon-nucleon scattering lengths using chiral perturbation theory. The leading nonanalytic SU(3) corrections reduce the coupling of the Λ(1405) to KN compared to Σπ. S-wave Kp scattering is the only channel significantly affected by the Λ(1405) pole which substantially cancels against the leading term fixed by the vector current. This cancellation and the cl...
Influenza virus (IV) is a continuously evolving virus that widely spreads in humans and contributes to substantial morbidity and mortality. Re-emergence of human infection with avian influenza virus H5N1 poses extra challenge to IV control. Artificial microRNA (amiRNA)-mediated RNA interference has become a powerful antiviral approach due to its high specificity and rapid effect. Here, we desig...
in this paper, we study a class of boundary value problem involving the p-laplacian oprator and singular nonlinearities. we analyze the existence a critical parameter $lambda^{ast}$ such that the problem has least one solution for $lambdain(0,lambda^{ast})$ and no solution for $lambda>lambda^{ast}.$ we find lower bounds of critical parameter $lambda^{ast}$. we use the method ...

In this paper, we investigate the existence of positive solutions for the ellipticequation $Delta^{2},u+c(x)u = lambda f(u)$ on a bounded smooth domain $Omega$ of $R^{n}$, $ngeq2$, with Navier boundary conditions. We show that there exists an extremal parameter$lambda^{ast}>0$ such that for $lambda< lambda^{ast}$, the above problem has a regular solution butfor $lambda> lambda^{ast}$, the probl...
Inthis paper, the main aim is to introduce the class $mathcal{U}_p(lambda,alpha,beta,k_0)$ of $p$-harmonic mappings togetherwith its subclasses $mathcal{U}_p(lambda,alpha,beta,k_0)capmathcal {T}_p$ and $mathcal{U}_p(lambda,alpha,beta,k_0)capmathcal {T}_p^0$, andinvestigate the properties of the mappings in these classes. First,we give a sufficient condition for mappings to be in $mathcal{U}_p(l...
