We report a novel size-insensitive method, iso-acoustic focusing (IAF), that can, for the first time, analyze and separate cells based on their intrinsic acoustic properties. We characterize the IAF system using two different cell lines and apply it to measuring the acoustic impedance of two subgroups of white blood cells (WBC): neutrophils and lymphocytes. We find cell type specific differences i
The UNESCO Post-2015 Development Agenda proposes equitable quality education and lifelong learning for all as its overarching goals for education. A holistic quality approach is espoused to encourage lifelong learning and thereby build inclusive, sustainable, and prosperous societies. Their quality goals are particularly ambitious given that the practical recommendations for inclusive education ne
Dissipative particle dynamics (DPD) have been widely used for the simulations of dynamics of both simple and complex fluids at nano/micro scales. In these simulations, periodic boundaries are usually employed in the main flow direction and the characterization of the flow and heat transfer is based on fully developed conditions. In the real nano/micro-fluidic devices, however, there are entrances
This paper presents the characterization and optimization of acoustic capture of platelet-derived microparticles (PMPs) from human plasma. The technique is compared to a standard preparation protocol using differential centrifugation on biobank samples from patients with ST-elevation myocardial infarction (STEMI). The main advantages of this new method are the capability of rapidly capturing micro
Due to their direct coupling to the physiology of the cells, the physical properties are especially attractive as markers for sorting and characterization of cancer cells. Where molecular surface markers are lacking, the physical properties can instead serve as inherent markers for separation. This is especially interesting for cancer cells where there are indications that soft cells are more meta
We have created devices that are extremely simple to fabricate, function without pumps, are reusable and capable of dealing with very large differences in particle sizes without clogging. Our new approach to microfluidic particle sorting is precise enough for applications in blood fractionation, cancer cell sorting, parasite detection and sample decomplexing in general. We achieve this using Deter
We discuss some of the effects of twisted boundary conditions in finite volume using continuum SU(3) Chiral Perturbation Theory. We point out how broken cubic symmetry affects the definitions of quantities such as form-factors. Using the π+ as an example, we give one loop results for the mass, decay constants and electromagnetic form-factor and illustrate how the relevant Ward identities are satis
Flexible multibody dynamics (FMD) has found many applications in control, analysis and design of mechanical systems. FMD together with the theory of structural optimization can be used for designing multibody systems with bodies which are lighter, but stronger. Topology optimization of static structures is an active research topic in structural mechanics. However, the extension to the dynamic case
Recent progress on colour reconnection within the Pythia framework is presented. A new model is introduced, based on the SU(3) structure of QCD and a minimization of the potential string energy. The inclusion of the epsilon structure of SU(3) gives a new baryon production mechanism and makes it possible simultaneously to describe hyperon production at both e+e- and pp colliders. Finally, predictio
We discuss finite volume effects and partial quenching for Chiral Perturbation Theory in the mesonic sector. The effects are computed in terms of analytical expressions for masses, decay constants and vacuum expectation values (VEVs) to two-loop order. Numerical examples are presented for a number of interesting and relevant cases. All numerical programs are publically available, the prospects of
During the 2009-2013 data taking period (Run I) LUCID was successfully providing information about the luminosity delivered to ATLAS by the LHC. Starting from 2015 (Run II) the LHC machine is expected to provide about twice larger peak instantaneous luminosity and the bunch spacing in the machine is decreased by factor of two (from 50 ns to 25 ns). The original LU-CID design could not cope with th
Pierre Bourdieu has been an extraordinarily influential figure in the sociology of music. For over four decades, his concepts have helped to generate both empirical and theoretical interventions in the field of musical study. His impact on the sociology of music taste, in particular, has been profound, his ideas directly informing our understandings of how musical preferences reflect and reproduce
In Skånska årsfester in 1973, I described a few Christmas pranks from the Scanian Recording Collections. The best covered research, "go Christmas ghost" remained untreated. The custom was known since at least the mid-18th century and appeared in most of Scania and a few parishes in Blekinge until the 1930s. Young people made themselves unrecognizable by girls being dressed in outmoded male clothin
Large volumes of data from satellite sensors with high time-resolution exist today, e.g. Advanced Very High Resolution Radiometer (AVHRR) and Moderate Resolution Imaging Spectroradiometer (MODIS), calling for efficient data processing methods. TIMESAT is a free software package for processing satellite time-series data in order to investigate problems related to global change and monitoring of veg
