Smart card data and survey data have different characteristics, which combined have the potential to enrich the total level of information as well as to reduce inherent biases in each dataset. This paper describes a fruitful procedure to use survey data from a smartphone application-based travel survey with prompted recall to validate data from smart card transactions in the same geographical area

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

To evaluate the effect of antibiotic drugs, it is important that the cells that are killed can be sorted from the cells that are resistant to the antibiotics. Here we report a simple label-free method for the continuous separation of viable/non-viable cells using Electrokinetic Deterministic Lateral Displacement. In general, this opens up for continuous sorting of a population of cells that is hom

We report a simplified, integrated and more efficient way of preparing DNA for analysis. We have developed a microfluidic platform that can purify DNA and subsequently label and stretch it on a surface. We have successfully extracted DNA from a gel-filled microfluidic channel using electrophoresis and subsequently stretched the DNA linearly by absorption to either a hydrophobic or a positively-cha

We investigate vascular changes during Photodynamic therapy (PDT) of skin tumors using optical Doppler tomography (ODT). The effect of vascular shut down on tumor destruction is currently not known, and to optimize treatment it is relevant to investigate this issue further. Optical Doppler tomography is capable of measuring blood flow in biological tissue down to 1-2 mm with sub-mm/s velocity sens

Integrated models including optics, structures, control systems, and disturbances are important design tools for Extremely Large Telescopes (ELTs). An integrated model has keen formulated for the European ELT and it includes telescope structure, main servos, primary mirror segment control system, wind, optics, wavefront sensor, deformable mirror, and an AO reconstructor and controller. There are t

Nodding syndrome is an emerging disease which have unknown transmission patterns and no properly established mechanisms for diagnosis leading to numerous hypothetical postulations. It has affected thousands of children in Uganda with debilitating effect and serious economic consequences. Spatial-temporal analysis may provide a quick mechanism to establish comparative understanding of the various h

Under the application of longitudinal electric fields in microchannels, microparticles experience lift forces that push them away from the channel walls and affect their trajectories. At high frequencies (>100KHz) the dielectrophoretic forces dominate and are well understood but at lower frequencies there is little agreement as to the exact nature of the forces, how they are generated and how they

As researchers we are often faced with the difficult and demanding task of preparing models, and their computer implementations, for decision making, or, more recently, for integrated assessment. Such assessment often involves large scale problems, where the decisions to be made can deeply affect the environment, the social context and the economic background of regions and even nations. Yet, we f

Structural Health Monitoring (SHM) provides real-time information about structural damage and its evolution over time, which supports decision-makers in managing structural integrity. However, traditional SHM systems, such as vibration-based systems with accelerometers, require laborious installation and maintenance of instrumentation, including sensors, cables, and acquisition systems directly in

In microbiology, cell analysis is an important tool for understanding influences on biotechnological production. Using current bulk methods, the secretome cannot be assigned to the corresponding cell. This contribution reports a novel method for cell separation inside microscale droplets. Cells are focused in droplets using bulk acoustic waves before the droplet is split at a bifurcation. For a wi

Structural Health Monitoring (SHM) plays a vital role in maintaining the integrity of structures by providing continuous information about damage or anomalies. Vibration-based SHM, which focuses on the dynamic behavior of structures, offers insights into structural conditions through changes in dynamic properties. Among SHM approaches, damage localization is crucial for pinpointing the geometric l

Support for Machine Learning (ML) applications in networking has significantly improved over the last decade. The availability of public datasets and programmable switching fabrics (including low-level languages to program them) presents a full-stack to the programmer for deploying in-network ML. However, the diversity of tools involved, coupled with complex optimization tasks of ML model design a

Background: Neuropsychiatric symptoms (NPS) are highly prevalent in Alzheimer's disease (AD) and are associated with negative outcomes. However, NPS are currently underrecognized at the memory clinic and non-pharmacological interventions are scarcely implemented. Objective: To evaluate the effectiveness of the Describe, Investigate, Create, Evaluate (DICE) method™ to improve the care for NPS in AD

The inherent properties of cells and micro-organisms is an under-explored source of specificity for particle sorting. In contrast to standard immunolabeling it allows us to perform fractionation without any chemical preparation of the sample. This improves the accessibility and affordability of the technology. Our contribution in the field is to extend the scope of deterministic lateral displaceme
