The heat transfer rate of the thermal Marangoni convective flow of a hybrid nanomaterial is optimized by using the response surface methodology (RSM).The thermal phenomenon is modeled in the presence of a variable inclined magnetic field,thermal radiation
In this study,a mathematical model is formulated to examine the blood flow through a cylindrical stenosed blood vessel.The stenosis disease is caused because of the abnormal narrowing of flow in the body.This narrowing causes serious health issues like he
The thermodynamic features of the Reiner-Rivlin nanoliquid flow induced by a spinning disk are analyzed numerically.The non-homogeneous two-phase nanofluid model is considered to analyze the effect of nanoparticles on the thermodynamics of the Reiner-Rivl
The phenomenon of stochastic bifurcation driven by the correlated non-Gaussian colored noise and the Gaussian white noise is investigated by the qualitative changes of steady states with the most probable phase portraits.To arrive at the Markovian approxi
The Liaoning clawed salamander (Onychodactylus zhaoermii) is an endemic and critically endangered amphibian species of China.To study the population genetics of natural populations of this species,32 samples were collected from six different locations,and
In many industrial applications,heat transfer and tangent hyperbolic fluid flow processes have been garnering increasing attention,owing to their immense impor-tance in technology,engineering,and science.These processes are relevant for polymer solutions,
The non-Newtonian fluid model reflects the behavior of the fluid flow in global manufacturing progress and increases product performance.Therefore,the present work strives to analyze the unsteady Maxwell hybrid nanofluid toward a stretching/shrinking surf
(本讲适合高中)rn数论问题通俗易懂,但解法变化多样,需要一定的逻辑推理能力和计算能力.数论又称为思维的体操,是数学竞赛中的一个重要组成部分.解决数论问题不但需要一定的基础知识,更需要掌握数论问题的常见思维方法,逐步探索正确的解题路线.本文以近几年数学竞赛题为例说明几种常规思路.

We describe Odorrana liboensis sp.nov.,a new species from the Maolan National Nature Reserve,Libo County,Guizhou Province,China.Phylogenetic analyses based on DNA sequences of the mitochondrial 12S rRNA,16S rRNA,and ND2 genes supported the new species as
A new species of microhylid frog of the genus Glyphoglossus Günther,1869 is described from Huadianba,Cangshan Mountain,Dali Bai Autonomous Prefecture,Yunnan Province,China.Glyphoglossus huadianensis,new species,is compared with congeners from China and ot
