OBJECTIVE To compare the effects of an 8-week, high-intensity interval training protocol versus continuous training. DESIGN Randomized controlled trial. SETTING Cardiac rehabilitation center. PARTICIPANTS Patients (N=26; mean age ± SD, 54±12y) with chronic heart failure were enrolled in a cardiac rehabilitation program for 8 weeks. INTERVENTIONS Patients were randomly assigned into 2 gr...

We provide quantitative measurements of night vision device (NVD) halos formed by light sources as a function of intensity and distance, describe a method to simulate their effects in the lab and present results from psychophysical experiments designed to analyze haloinduced errors in slope estimation. The effective halo generating potential of a point source is presumed to be a function of amb...

HSI (hue, saturation, intensity) color space is widespread used in image processing community. H, S and I components corresponds the way human perceives color and they make possible to separate chromatic (hue and saturation) and achromatic (intensity) information. Cylindrical distance is measure of color difference that takes into account angular differences and it is suitable for color spaces ...

As the use of information and communication technologies (ICT) is embraced in Uganda, determinants of awareness of ICT based projects remain unknown. The intensity of use of mobile phones among smallholder farmers in the areas where such projects operate is unclear. To address this knowledge gap, 346 smallholder farmers in two ICT project sites in Mayuge and Apac districts were subjected to eco...

We consider a stationary Poisson hyperplane process with given directional distribution and intensity in d-dimensional Euclidean space. Generalizing the zero cell of such a process, we fix a convex body K and consider the intersection of all closed halfspaces bounded by hyperplanes of the process and containing K. We study how well these random polytopes approximate K (measured by the Hausdorff...

For coherent X-ray imaging of pure phase objects we study the reliability of linear relations in phase-retrieval algorithms based on a single intensity map after free-space propagation. For large phase changes and/or large propagation distances we propose two venues of working beyond linearity: Projection onto an effective, linear and local model in Fourier space and expansion of intensity cont...

We analyze the anonymous communication patterns of 2.5 million customers of a Belgian mobile phone operator. Grouping customers by billing address, we build a social network of cities that consists of communications between 571 cities in Belgium. We show that inter-city communication intensity is characterized by a gravity model: the communication intensity between two cities is proportional to...

UNLABELLED The objective of this work was to examine the effects of magnet distance (and by proxy, field strength) on nanomagnetic transfection efficiency. METHODS non-viral magnetic nanoparticle-based transfection was evaluated using both static and oscillating magnet arrays. RESULTS Fluorescence intensity (firefly luciferase) of transfected H292 cells showed no increase using a 96-well Nd...

(1) The intensity of cosmic rays is practically independent of time. This fact indicates that the origin of these rays can be sought neither in the sun nor in any of the objects of our own Milky Way. (2) The decrease in intensity of cosmic rays in equatorial regions has successfully been explained by assuming that at least a part of the rays consists of very energetic, positively or negatively ...

This research examines whether technology transfer, research intensity, educational attainment and the ability to absorb foreign technology help explain cross-country differences in productivity growth. Our data comprise a panel of 55 countries including 23 OECD and 32 developing economies over the period 1970-2004. The results show that TFP growth in both OECD and developing countries is posit...
