A combined biochemical and genetic approach was used to show that phospholipase C in the cellular slime mould Dictyostelium is under dual regulation by the chemoattractant cyclic AMP (cAMP). This dual regulation involves stimulatory and inhibitory surface receptors and G-proteins. In wild-type cells both cAMP and guanosine 5'-[gamma-thio]triphosphate (GTP[S]) stimulated phospholipase C. In cont...

Let $$p\in [1,\infty ]$$ , $$q\in )$$ $$s\in \mathbb {Z}_+:=\mathbb {N}\cup \{0\}$$ $$\alpha \in {R}$$ and $$\beta (0,1)$$ . In this article, the authors first find a reasonable version $$\widetilde{I}_{\beta }$$ of (generalized) fractional integral $$I_{\beta on special John–Nirenberg–Campanato space via congruent cubes, $$JN_{(p,q,s)_{\alpha }}^{\textrm{con}}(\mathbb {R}^n)$$ which coincides ...

in this note we consider the notion of intuitionistic fuzzy (weak) dual hyper k-ideals and obtain related results. then we classify this notion according to level sets. after that we determine the relationships between intuitionistic fuzzy (weak) dual hyper k-ideals and intuitionistic fuzzy (weak) hyper k-ideals. finally, we define the notion of the product of two intuitionistic fuzzy (weak) du...

We consider bosonic string theory on $\text{AdS}_3$ supported by Kalb-Ramond flux. It is well known that the $\alpha'$ exact worldsheet described $\text{SL(2,R)}$ WZW model. In this note we perform checks of an dual description proposed in [arXiv:2104.07233] involving a winding condensate free background. give explicit map vertex operators for normalizable states both sides duality and demonstr...

‎we present an application of the dual gabor frames to image‎ ‎processing‎. ‎our algorithm is based on finding some dual gabor‎ ‎frame generators which reconstructs accurately the elements of the‎ ‎underlying hilbert space‎. ‎the advantages of these duals‎ ‎constructed by a polynomial of gabor frame generators are compared‎ ‎with their canonical dual‎.

In this paper we study positive solutions to the following nonlocal system of equations: \begin{equation*} \left\{\begin{aligned} &(-\Delta)^s u = \frac{\alpha}{2_s^*}|u|^{\alpha-2}u|v|^{\beta}+f(x)\;\;\text{in}\;\mathbb{R}^{N}, v \frac{\beta}{2_s^*}|v|^{\beta-2}v|u|^{\alpha}+g(x)\;\;\text{in}\;\mathbb{R}^{N}, & \qquad u, \, >0\, \mbox{ in }\,\mathbb{R}^{N}, \end{aligned} \right. \end{equation*...
