In some simulations, axes are not perpendicular. Your must validate the angle between axes (e.g., 60° for hexagonal crystals). Check that shear components are correctly applied.

While MathWorks has moved toward more formal argument validation (like arguments blocks), axescheck remains useful because it uses an undocumented, high-speed variant of ishghandle to verify if a handle specifically belongs to an axes object. Developers can find examples of its implementation in community-maintained toolboxes like irfu-matlab on GitHub . 2. axesCheck for PDF Accessibility

is a free, web-based tool used to instantly validate the accessibility of PDF documents against international standards. It is specifically designed to identify whether a PDF is compliant with PDF/UA (ISO 14289-1) and WCAG 2.1 Level AA requirements. Key Features of axesCheck

to automate the creation of compliant documents directly from Microsoft Word. Don't leave accessibility to chance. Use

Metaphorically, the "Axis Check" offers a profound lesson for personal and organizational leadership. In life, individuals set a "true north"—a set of values, goals, or moral principles that guide their decisions. However, daily distractions, stress, and external pressures can act as friction, slowly pulling a person off their axis. Without a regular "axis check"—a moment of introspection and self-audit—it is easy to drift unknowingly from one’s intended course. Just as a pilot must constantly adjust the plane’s axis to account for wind and weather, individuals must realign their actions with their core values to ensure they reach their desired destination.
