Real-Time Event-Based Unsupervised Feature Consolidation and Tracking for Space Situational Awareness.

Earth orbit is a limited natural resource that hosts a vast range of vital space-based systems that support the international community's national, commercial and defence interests. This resource is rapidly becoming depleted with over-crowding in high demand orbital slots and a growing presence of space debris. We propose the Fast Iterative Extraction of Salient targets for Tracking Asynchronously (FIESTA) algorithm as a robust, real-time and reactive approach to optical Space Situational Awareness (SSA) using Event-Based Cameras (EBCs) to detect, localize, and track Resident Space Objects (RSOs) accurately and timely.

Heterosexual partner acquisition rates in the Australian population.

The rate of partner acquisition in a population is an important parameter when constructing epidemiological models of sexually transmissible infections. We have analysed the results of a survey of the sexual behaviour of the Australian population to estimate how many people have acquired no new partner, one, two or at least three new partners in the past year, and hence estimated heterosexual partner acquisition rates for the population by gender and age band. Partner acquisition rates are ~0.
