Abstract We describe a user-friendly, open source software for single-particle detection/counting in continuous-flow. The tool automatically processes video images of particles, including pre-conditioning, followed by size-based discrimination independent detection fluorescent and non-fluorescent particles different sizes. This is done interactive tuning reduced set parameters that can be check...

Multi-photon absorption is a well-known phenomenon. With atom lasers a similar process could take place for massive particles, the ionization of an atom or molecule by the successive interaction with various particles. This process would lead to multi-particle detection events for incident multi-particle beams. We show that two-particle detections would introduce a correction (proportional to t...

The ability of raptorial zooplankton to find large particles such as marine aggregates is crucial to their use of the particles as food and to the fate of the particles. Kiørboe & Thygesen (2001) developed a numerical approach to describe particle detection by chemosensory zooplankton. In this paper, we develop and test a simplified mathematical description of the process and explore the ecolog...

BACKGROUND Magnetic Particle Imaging is a novel method for medical imaging. It can be used to measure the local concentration of a tracer material based on iron oxide nanoparticles. While the resulting images show the distribution of the tracer material in phantoms or anatomic structures of subjects under examination, no information about the tissue is being acquired. To expand Magnetic Particl...

This article describes a new technique for modelling the dynamic behaviour of elastic textiles. The technique is derived from cellular automata theory and describes the folds and wrinkles that can be seen on garments draped over one or more obstacles, the human body being one example. Integrating immovable objects into the model requires some form of collision and self-collision detection. Comp...

In this paper we describe a method of determining the separation plane of two objects during collision detection. This method is specifically designed for volumetric particle representations of objects, volpars. This particular technique offers an advantage over previous methods because it only looks for a separating plane for the areas local to the point of contact. This increases the robustne...

We study the possibility of detecting the Higgs boson in the intermediate mass range via its two jet channel. We consider only Higgs bosons produced in association with a t ¯ t pair. Both t and ¯ t are required to decay semileptoni-cally to reduce the QCD background. The signal is compared with the main background, t ¯ t + 2 jets, after appropriate cuts. A sizable signal above background is see...

An introductory review, suitable for the beginning student of high-energy physics or professionals from other fields who may desire familiarity with subatomic-particle detection techniques. Subatomic-particle fundamentals and the basics of particle interactions with matter are summarized, after which we review particle detectors. We conclude with two examples that illustrate the variety of suba...
