This paper considers the use of the EM-algorithm, combined with mean field theory, for parameter estimation in Markov random field models from unlabelled data. Special attention is given to the theoretical justification for this procedure, based on recent results from the machine learning literature. With these results established, an example is given of the application of this technique for an...

Ferromagnetic resonance (FMR) in exchange-coupled bilayer films has been the subject of intensive studies in recent years. From the experimental viewpoint, a characteristic feature of this FMR is that some specimens show single resonance, whereas others show double resonance. Moreover, double resonance can exhibit a regular pattern , in which the high-field (HF) line intensity surpasses that of...

INTRODUCTION Lipodystrophy is still a matter of concern in HIV+ patients receiving ART. However, long-term fat change in patients taking non-thymidine regimens is not well known. MATERIALS AND METHODS A prospective ongoing fat change assessment including clinical evaluation and dexa scans (Hologic QDR 4500) is being conducted in all consecutive patients initiating ART from January 2008. Arm, ...

The combined study of structural and magnetic properties of CoxAg12x heterogeneous films in a wide concentration range 0.18,x,0.82 was performed using nuclear magnetic resonance ~NMR!, X-band ferromagnetic resonance ~FMR!, and superconductive quantum interferometer ~SQUID! magnetometry. The structural investigation by NMR shows that at low Co concentrations rather large and pure cobalt clusters...

BACKGROUND Right ventricular dysfunction (RVdysf) is a predictor of poor outcome in patients with heart failure and valvular disease. The aim of this study was to evaluate the evolution and the impact of RVdysf in patients with moderate-severe functional mitral regurgitation (FMR) successfully treated with MitraClip. METHODS AND RESULTS From October 2008 to July 2014, 60 consecutive high surg...

Recent results suggest that wild Northern herbivores reduce their metabolism during times of low ambient temperature and food shortage in order to reduce their energetic needs. It is, however, not known whether domesticated animals are also able to reduce their energy expenditure. We exposed 10 Shetland pony mares to different environmental conditions (summer and winter) and to two food quantit...

Field metabolic rates (FMR) and activity patterns of black-browed albatrosses Thalassarche melanophrys were measured while at sea and on nest during the incubation stage at Kerguelen Island, southwestern Indian Ocean. Activity-specific metabolic rates of five albatrosses at sea (FMRat-sea) were measured using doubly labeled water (DLW), and by equipping birds with wet-dry activity data loggers ...

We investigate the coupled magnetization dynamics in heterostructures of a single crystal chiral magnet [Formula: see text] (CSO) and polycrystalline ferromagnet (Py) thin film using broadband ferromagnetic resonance (FMR) at cryogenic temperatures. observe excitation hybrid mode (HM) below helimagnetic transition temperature CSO. This HM is attributed to spin CSO/Py interface. study by measuri...
