We introduce the notion of exploitability in cut-and-choose protocols for repeated cake cutting. If a cut-and-choose protocol is repeated, the cutter can possibly gain information about the chooser from her previous actions, and exploit this information for her own gain, at the expense of the chooser. We define a generalization of cut-and-choose protocols—forced-cut protocols—in which some cuts...

This paper discusses a technique for building medical prototypes directly from medical image data using ruled thick layers directly from medical image data. Medical image slices are currently much thicker than the layers used by most machines, but a direct slice to layer correspondence can be established with the use of thick layers. The proposed algorithm uses three image planes to interpolate...

This article presents an overlooked case of research misconduct and violations of basic principles of medical and business ethics. When Bayer's Cutter Laboratories realized that their blood products, Factor VIII and IX or antihemophiliac factor (AHF), were contaminated with human immunodeficiency virus (HIV), the financial investment in the product was considered too high to destroy the invento...

In Olinda there are an estimated 50 marble quarries, 3 of which are members of the stone extraction and finishing industry's state union. The objective here is to quantitatively evaluate the noise present at the workplace in two of Olinda's unionized marble quarries. The data to be analyzed was collected during December 2010, this month representing one of the four busiest months of production....
