Estimation of backscattered echoes from underwater targets using block sparsity

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,

A Sparsity-Based Passive Multistatic Detector

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

Health related quality of life after liver transplantation

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

Pain and health related quality of life after heat-, kidney- and liver transplantation

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

Liver transplant recipient's ability to cope during the first 12 months after transplantation- a prospective study

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
