In this article, an improved memristive Hénon map is proposed by using the state variable difference instead of the state variable itself as the input of a discrete memristor. As a result, the ...

An endogenous variable is a variable in a statistical model that is changed or determined by its relationship with other variables within the model.

Not all interest rates work the same. Your choice among these two main types come down to how you save and how you borrow. Here's what to know about fixed and variable rates.

Variable expenses can change often, while fixed expenses generally do not — managing both is important for budgeting and reaching your financial goals ...

When assigning sequential local variable identifiers to optimize variable access (see #1167), the assigner is reset after each callable declaration. Unfortunately, that will reset the ids for the ...

Understanding the difference between the role that fixed and variable expenses play in your life can help you create a budget that prevents you from overspending.

But to illustrate how this sex difference could be evolved and culturally variable, let’s take a speculative look at how this could work.
