Four different types of free energies are computed by both thermodynamical Bethe Ansatz (TBA) techniques and by weak coupling perturbation theory in an integrable one-parameter deformation of the O(4) principal chiral σ-model (with SU(2)×U(1) symmetry). The model exhibits both ‘fermionic’ and ‘bosonic’ type free energies and in all cases the perturbative and the TBA results are in perfect agree...

A new world, digital image ratio (DIR), has been developed for directly measuring changes in alveolar bone. The image on the computer monitor represents the relative mass change between two radiographs. Fourier filtering is used to reduce noise artefacts. This method is validated through an experiment with a step wedge. DIR needs only a preliminary calibration of the experimental conditions of ...

Abstract We investigate the axion-like particle (ALP)-photon oscillation effect in high-energy -ray spectra of PG 1553+113 and PKS 2155?304 measured by Fermi-LAT H.E.S.S. The choice extragalactic background light (EBL) model, which induces attenuation observed spectra, affects ALP implications. For ordinary EBL model that prefers a null hypothesis, we set constraints on ALP-p...

In the last years, pattern recognition approaches using machine learning techniques to construct object detectors have encountered great success in the domain of visual detection. However, the application of automatic and robust player detection in sport videos is a particularly challenging task because of the small size, and high variability in shape and appearance of the objects to detect, an...

In the diagnosis of periodontal diseases, Digital Subtraction Radiography (DSR) is often used. A pair of dental radiographs is taken a few months apart. The difference between the two radiographs can be used as a basis for diagnosis. Even though the radiographs are in digital form, the alignment process to ensure an exact match between the two radiographs is done manually. Furthermore, there wo...

Obtaining the peak current ip from raw CV data The raw CV data obtained during the experiments featured two characteristics, which could potentially complicate the data analysis. First, because of the relatively high scan rate (10 V s) used for these experiments, the background current was quite important and could potentially hinder the determination of the concentration profiles from the volt...

microscopy. Quantitative analysis of the movies revealed a clear posterior-to-anterior gradient of cell motility and directionality in the PSM. We tracked the movement of the PSM extracellular matrix (ECM) in parallel to the labelled cells and substracted the ECM movement to the global motion of cells. After substraction, cell movements remained consistently graded but lacked directionality. Th...
