Despite being double the size of leading pure silicon transistors at the time, the company reported that they performed equally as well while consuming less power. [ 109 ] In 2011, researchers at Intel demonstrated 3-D tri-gate InGaAs transistors with improved leakage characteristics compared to traditional planar designs.
Square roots that are not the all-zeros matrix come in pairs: if R is a square root of M, then −R is also a square root of M, since (−R)(−R) = (−1)(−1)(RR) = R 2 = M. A 2×2 matrix with two distinct nonzero eigenvalues has four square roots. A positive-definite matrix has precisely one positive-definite square root.
A red-colored post pounder next to two green steel t-posts. A post pounder, post driver, post rammer, post knocker or fence driver is a tool used for driving fence posts and similar items into land surfaces. It consists of a heavy steel pipe which is closed at one end and has handles welded onto the sides. It is normally used by one person, but ...
A driving cap is a special type of pipe cap used to provide a striking surface for a hammer while simultaneously protecting the end of the pipe from deformation. [1] A driving cap is made of much thicker or more durable material than a standard pipe cap and is always removed once installation is complete.

In mathematics, the matrix sign function is a matrix function on square matrices analogous to the complex sign function. [ 1 ] It was introduced by J.D. Roberts in 1971 as a tool for model reduction and for solving Lyapunov and Algebraic Riccati equation in a technical report of Cambridge University , which was later published in a journal in 1980.
