For classical waves such as light or sound, diffraction sets a natural limit on how finely the details of an object can be recorded on its image. Recently, various optical superlenses based on the metamaterials concept have shown the possibility of overcoming the diffraction limit 1–7. Similar two-dimensional (2D) acoustic hyperlens designs have also been(More)
The data in this relies on a previous publication: "Altered leukocyte distribution under hypercholesterolemia: a cross-sectional study in children with familial hypercholesterolemia" (Christensen et al. 2016) [1]. In the present paper, whole blood leukocyte distribution and plasma inflammatory proteins were measured for association with cholesterol(More)
The concept of microwave sounding from geostationary orbit is now over three decades old and many projects are currently under studies at frequency bands of oxygen (54, 118 and 425 GHz) and water vapor (183 and 380 GHz). The primary advantage of a Geostationary Earth Orbit (GEO) for remote sensing, compared with a Low-Earth Orbit (LEO), is that continuous(More)
Sound Quality as a relatively new product parameter has become an important competition item among the car manufactures. Sound Quality metrics is the same as Sound Quality parameters, which can reflect most of the psychoacoustic properties of the human perception of sound. There are some standardized metrics, such as Stationary Loudness, Tone to Noise(More)
The cyclic polyether, 18-crown-6, reacts with protonated amines in methanol to form complexes whose formation constants (log K) decrease in the order NH4+, RNH3+ greater than R2NH2+ greater than R3NH+. In the case of the organic amines, this stability order is identical to the earlier observed permeability sequence for protonated organic amines in glyceryl(More)
