The impact parameter formalism of the single-center close-coupling, first-, and second-order Born approximations have been applied to investigate direct excitations of Helium He+(2s) and Lithium Li++(2s) ions by colliding with protons or antiprotons. The total 3s, 3p, and 3d scaled excitation cross sections are calculated in the scaled impact energy region (2 to 1000 keV). The present work aims...

In this paper, we consider the existence and asymptotic behaviours of solutions for following fractional equation$ \begin{align*} (-\Delta)^{s}u+\lambda u = \mu(I_{\alpha}\star|u|^p)|u|^{p-2}u+|u|^{2_{s}^{*}-2}u, \quad x\in \mathbb{R}^N, \end{align*} $under constraint$ \int_{\mathbb{R}^N}|u|^2dx c^2, $where $ N\ge2, \; I_{\alpha} \frac{1}{|x|^{N-\alpha}}, \alpha\in(N-2s, N), 2\le p<1+\frac{\...

This study aims to analyze the influence of fibrils oscillations and connections on effective hygro-elastic behavior wood cell wall. For that, two different models microstructure describing wall are introduced: model 1S, for which allowed oscillate in one direction like a sine curve, 2S, directions as helix. The associated with each is computed by numerical periodic homogenization. Then, we eff...

In this article, we study the blow-up and instability of standing waves for theinhomogeneous fractional Schrodinger equation $$ i\partial_tu-(-\Delta)^su+ |x|^{-b}|u|^{p}u=0, where \(s\in (\frac{1}{2},1)\), \(0<b<\min \{2s,N\}\) \(0<p< \frac{4s-2b}{N-2s}\). \(L^2\)-critical \(L^2\)-supercritical cases, i.e.,\(\frac{4s-2b}{N}\leq p< \frac{4s-2b}{N-2s}\), establish general criteria...

The human protein Cox17 contains three pairs of cysteines. In the mitochondrial intermembrane space (IMS) it exists in a partially oxidized form with two S-S bonds and two reduced cysteines (HCox17(2S-S)). HCox17(2S-S) is involved in copper transfer to the human cochaperones Sco1 and Cox11, which are implicated in the assembly of cytochrome c oxidase. We show here that Cu(I)HCox17(2S-S), i.e., ...

Dielectronic recombination (DR) of beryllium-like Xe was investigated by using the ESR electron cooler as a free electron target. Three series of resonances associated with excitations from the 2s ground state could be measured (Fig. 1), namely 2s → 2s2p P1, 2s → 2s2p P1 and 2s → 2s2p P2. The resonances of the 2s2p P2 nj manifolds are much weaker than the ones of the other series. No signatures...

Bupropion is an atypical antidepressant that also has usefulness as a smoking-cessation aid. Because hydroxybupropion, a major metabolite of bupropion, is believed to contribute to its antidepressant activity, this metabolite may also contribute to the smoking-cessation properties of bupropion. This study investigated the effects of hydrobupropion enantiomers on monoamine transporters and nicot...

(3S)-Acetoin and (2S,3S)-2,3-butanediol are important platform chemicals widely applied in the asymmetric synthesis of valuable chiral chemicals. However, their production by fermentative methods is difficult to perform. This study aimed to develop a whole-cell biocatalysis strategy for the production of (3S)-acetoin and (2S,3S)-2,3-butanediol from meso-2,3-butanediol. First, E. coli co-express...

Resistance to proteolytic enzymes and heat is thought to be a prerequisite property of food allergens. Allergens from peanut (Arachis hypogaea) are the most frequent cause of fatal food allergic reactions. The allergenic 2S albumin Ara h 2 and the homologous minor allergen Ara h 6 were studied at the molecular level with regard to allergenic potency of native and protease-treated allergen. A hi...
