1. Biological Insights from Single-Particle Tracking in Living Cells
Abstract : Single-particle tracking is a technique that allows for quantitative analysis of the localization and movement of particles. In this technique, trajectories are constructed by determining and connecting the positions of individual particles from consecutive images. READ MORE

2. Optical characterisation of subwavelength dielectric particles using particle tracking beyond the Stokes-Einstein relation
Abstract : As the importance of nanoparticles continues to increase in both biology and industrial processes, so does the need for accurate and versatile characterisation methods. However, most light-based methods to quantify size and refractive index of individual particles are either limited to snapshot observations, particles larger than the wavelength of light, non-dynamic particle properties, or assuming the hydrodynamic boundary conditions without experimental evaluation.

3. Impedance and Instabilities in the MAX IV 3 GeV Ring
Abstract : To ensure the beam with an ultralow emittance and high current the possible effects deteriorating the beam stability must be investigated. When ultrarelativistic particles travel in the vacuum chamber they induce electromagnetic fields which can act back on them and the following particles. READ MORE

4. Macroscopic modeling of fluid dynamics in large-scale circultaing fluidized beds
Abstract : Satisfactory knowledge of the fluid dynamics governing the gas-solid flow in large-scaleCirculating Fluidized Bed (CFB) units is still lacking, although the CFB technology is widelyused for power (and heat) generation. Due to the complex two-phase flow in large CFB unitsfluid dynamical modeling of practical use is so far limited to a macroscopic approach andavailable models generally focus in describing one of the following key-phenomena: maingas-solid flow pattern, mixing of fuel particles and gas mixing.

5. Three-Dimensional Simulation and Physical Modelling of Flows in Detention Tanks - Studies of Flow Pattern, Residence Time and Sedimentation
Abstract : Improving effluent water quality to receiving waters using stormwater ponds and storage tanks is acknowledged to be an effective method. The performance of the method depends however on flow conditions such as velocity distribution, short-circuiting currents and the volume through which the influent water flows, the so called effective volume.
