This article will take you through the basics.

To properly assess the state of your business, it is important your accounts show the value of this asset.Īccounting for inventory, and similar assets such as Raw Materials and Work in Progress/Unfinished Goods is a fairly advanced accounting topic. Due to its fast response and high precision, the experimental configuration is particularly suited for studying movements of motor proteins along biological filaments.When you spend money to build up a stock of items that you can sell, you have converted cash into an asset known as inventory. While phase shifts provide information on displacements in the xdirection of the measurement plane (see figure), the intensity provides information of displacements in the z direction, though with less accuracy. The phase and intensity of the scattered light depend sensitively on the position of the bead within the pattern and their simultaneous measurement allows the determination of the bead’s sub-nanometer displacement. The principle of this novel optical technique is based on tracking the movement of a single metallic nanoparticle (~80nm), which scatters light from a rapidly shifting interference pattern under total internal reflection. Currently, the experimental set-up is rendering its first results. Beyond these impressive specs, this new technique is unique in the sense that it does not apply external forces on the systems under study, thus detecting the natural dynamics with minimum external perturbations. This allows us to scrutinize processes not only at biological relevant length scales but also at temporal scales required to observe their real time dynamics. Travelling wave tracking is a technique that attains subnanometer spatial resolution (~0.3nm RMS) and ~10 microsecond temporal resolution.
