In this article, we give the extended trial equation method for solving nonlinear partial differential equations with higher order nonlinearity. By use of this method, the exact travel-ing wave solutions including soliton solution, singular soliton solutions, rational function solution and elliptic integral function solution to one-dimensional general improved KdV (GIKdV) equation and Rðm; nÞ e...
We are concerned with an isothermal model of viscous and capillary compressible fluids derived by J. E. Dunn Serrin (1985), which can be used as a phase transition model. Compared the classical Navier-Stokes equations, there is smoothing effect on density that comes from terms. First, we prove global solutions critical regularity have been constructed in [11] second author B. Desjardins (2001),...
Let G be a finite, undirected, d-regular graph and A(G) its normalized adjacency matrix, with eigenvalues 1=?1(A)????n??1. It is classical fact that ?n=?1 if only bipartite. Our main result provides quantitative separation of ?n from ?1 in the case Cayley graphs, terms their expansion. Denoting hout by (outer boundary) vertex expansion G, we show non-bipartite (constructed using group symmetric...
Epithelial (E)-cadherin-mediated cell-cell junctions play important roles in the development and maintenance of tissue structure in multicellular organisms. E-cadherin adhesion is thus a key element of the cellular microenvironment that provides both mechanical and biochemical signaling inputs. Here, we report in vitro reconstitution of junction-like structures between native E-cadherin in livi...

Online learning process in COVID-19 pandemic can decline the quality of subjective well-being students. The constraints faced by students doing online make them more frequently feel negative emotions such as being anxious, stressful, confused or bored. aim this study is to test readiness and academic resilience on among A number previous researches showed that ready have having a good could inc...
The low-energy scattering of ortho positronium (Ps) by H, He, Ne, and Ar atoms has been investigated in the coupled-channel framework by using a recently proposed timereversal-symmetric nonlocal electron-exchange model potential with a single parameter C. For H and He we use a three-Ps-state coupled-channel model and for Ar and Ne we use a static-exchange model. The sensitivity of the results i...
