In this work, we introduce a block sparse reconstruction technique to estimate backscattered echoes from underwater targets. The backscattered field of a spherical shell or the broadside scattering of a cylindrical shell contains a specular reflection as well as some elastic leaky surface waves, while the elastic parts appear as a periodic signal, which may be modeled using a block pattern. Thus,
In this paper, we examine the problem of target detection for the multistatic passive radar. Passive radar systems leverage the existing wireless sources, such as radio/TV stations and cellular signals that are referred to as illuminators of opportunity (IOs), to illuminate the environment and provide surveillance functions. Usually, these IO source signals are sparse or locally sparse in the freq
To gather information regarding how to best assist liver transplant recipients in improving their self‐care capacity and well‐being, we investigated their total health situation. A retrospective, cross‐sectional survey with up to a 10‐year follow‐up concerning experienced health and quality of life after liver transplantation (LTX) was conducted. The aim of this study was to provide descriptive da
No study has focused particularly on the sensory and affective experience of bodily pain among transplanted patients. The aim of this study was to explore pain and other factors that influence health related quality of life (HRQOL) in heart, kidney, and liver transplant recipients during the first 2 yr after transplantation, and to define similarities and/or differences in the three groups. A tota
Little is known about the coping style and coping strategies among liver transplant recipients. The aim of this study was to evaluate the change in the sense of coherence and coping strategies among liver transplant recipients before and during the first year after liver transplantation. The aim was also to study whether or not there was any relationship between the sense of coherence and the copi
The way organ transplant recipients depend on social interactions to develop and experience social health and well-being is similar to that of the general population. A transplant may result in a close to full recovery of health status, but the physical and social problems can persist in some patients. The focus on improving the recipients’ social participation has therefore become an important is
