It does, however, lead to an interesting question about what constitutes the “materiality” of a material object. In this article I propose to solve the conun­ drum, and to say a l...

Re-solving the cadherin-catenin-actin conundrum.

Cell-cell adhesion plays critical roles in establishing and maintaining tissue architecture and function (1,2). In these roles, cell-cell adhesion must be adaptable and, depending on the biological circumstance, weak, dynamic or strong. Different adhesion structures (adherens junctions, tight junctions, desmosomes) regulate cell-cell adhesion, and each comprises distinct membranebound adhesion ...

the algorithm for solving the inverse numerical range problem

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
