In some cases, the thinning of the interface also generates a gradient in surface tension. Essentially, the water drains out, leaving a higher soap concentration. But soap has a lower surface ...

Thus, gene expression is vital to the effectiveness of the gradient in specifying different cell fates. The presence of a Dpp gradient in fruit fly wings has been demonstrated in living flies ...

Side view of the LEGO gradient mixer during (A) its initial position and (B) its horizontal tilting phase. (1) 3D printed centrifuge-tube holder. (2) Spinning motor to rotate the tubes while in ...

Why does gradient descent work? Specifically, what can we guarantee about the point it converges to? In addition to gradient descent, we explore a large variety of optimization methods. What are the ...
