Anatomy is one of the oldest branches of medicine, dating back as far as the third century BC . Throughout time, the discipline has been served well by a universal system for describing structures based on the anatomic position . Unfortunately, cardiac anatomy has been a detractor from this long-standing tradition and has commonly been incorrectly described using confusing and inappropriate nom...

The terms “gamma” and “gamma correction” are well‐known to most graphics practitioners. They describe a fundamentally simple but some‐ times confusing method used in print, imaging and video technology, which also plays an impor‐ tant role in 3D computer graphics and composit‐ ing. Even though most have heard the terms be‐ fore, there are many misconceptions about gamma correction, especially i...

A new method for improving the resolution of astronomical images is presented. It is based on the principle that sampled data cannot be fully deconvolved without violating the sampling theorem. Thus, the sampled image should not be deconvolved by the total Point Spread Function, but by a narrower function chosen so that the resolution of the deconvolved image is compatible with the adopted samp...

Floating-point numbers are an essential part of modern software, recently gaining particular prominence on the web as the exclusive numeric format of Javascript. To use floating-point numbers, we require a way to convert binary machine representations into human readable decimal outputs. Existing conversion algorithms make trade-offs between completeness and performance. The classic Dragon4 alg...

For a ring R, call a class C of R-modules (pure-) mono-correct if for any M,N ∈ C the existence of (pure) monomorphisms M → N and N → M implies M ' N . Extending results and ideas of Rososhek from rings to modules, it is shown that, for an R-module M , the class σ[M ] of all M -subgenerated modules is mono-correct if and only if M is semisimple, and the class of all weakly M -injective modules ...
