Early diagnosis of human cancer is of crucial importance for successful therapies. Cancer diagnosis via ESR (Electron-Spin-Resonance) spectroscopy of albumin found in human blood provides a new promising approach. The ESR frontend signal processing follows a protocol of our proprietary 'mobility of molecular structure test' (MMS-Test) and provides a real-valued 33-dimensional vector representation per sample, which combines a representative feature set of the binding ability (spin-probes) of albumin under investigation. Classical statistical pattern recognition is then applied to the feature vector, including LDA and EM mixture density estimation, leading to a classification error rate of 14% between the two patient classes 'healthy' and 'suspect'. The class 'suspect' includes cancer and other chronic condition. The investigation was performed on a proprietary database of MedInnovation with 1176 cancer and non-cancer patients.

This paper proposes an environmental regulating system by using a multi-robot system in cooperation with wireless sensor networks. Wireless sensors pre-deployed in the environment and embedded in mobile robots can gather sensory information to estimate the distribution of environmental variable. The environment distribution is illustrated by a density function which is constructed by Gaussian mixture model based on expectationmaximization (EM) algorithm to estimate real condition. Subsequently, a gradient decent coverage control is proposed to drive the multi-robot system to cover the optimal distribution based on the estimated density function. Meanwhile, the actuators embedded on mobile robots are designed to regulate the environment to achieve a desired value of density function. Numerical examples are illustrated to show the performance of the proposed control system.
