Alex Muncy was still an apprentice at STIHL Inc. when the company enlisted him in revamping an automated packaging process. The package would contain the outdoor power equipment manufacturer’s signature trimmer line, the colorful cord used to give lawns a precise, neat appearance. The goal: satisfy the customer while cutting production costs. Muncy’s team developed a concept, designed the packa...

Modern imaging techniques enable researchers to observe drug actions and consequences as they occur and persist in the brains of abusing and addicted individuals. This article presents the five most commonly used techniques, explains how each produces images, and describes how researchers interpret them. The authors give examples of key findings illustrating how each technique has extended and ...

E+e--+ R+p-due to Slepton Mixing

We consider a softly-broken supersymmetry model in which explicit flavour mixing occurs in the supersymmetric sector. Attention has been restricted to the leptonic sector, and a model-independent approach has been adopted. For the reaction e'e-+ 2 " + r+p-at Z " energies, it is found that, for reasonable parameters, oe+e-+,+p-oe+e-+p+p-is 0 (lo-'-lo-"). Thus far violation of lepton family numbe...
