Accurate and low-cost autonomous self-localization is a critical requirement of various applications of a large-scale distributed wireless sensor network (WSN). Due to its massive deployment of sensors, explicit measurements based on specialized localization hardware such as the Global Positioning System (GPS) is not practical. In this paper, we propose a low-cost WSN localization solution. Our...

Force{Free Magnetic Fields, and Astrophysical Applications. Paul J. Dellar Department of Applied Mathematics and Theoretical Physics, University of Cambridge, Silver Street, Cambridge, CB3 9EW, UK [email protected] http://www.damtp.cam.ac.uk/user/pjd12 Many authors have studied the interaction of a magnetic eld with an accretion disk. These thin, approximately axisymmetric structures c...

We introduce a new generic filtering algorithm for handling constraint relaxation within constraint programming. More precisely, we first present a generic pruning technique which is useful for a special case of the cardinality operator where all the constraints have at least two variables in common. This method is based on a generalization of a sweep algorithm which handles a conjunction of co...

Mr. B, a 68-year-old man with a sevenyear history of lung cancer in remission, was admitted to the oncology unit for increasing dyspnea and extent of disease workup. He reported nonspecific symptoms that included shortness of breath on exertion and sometimes without exertion, causing him to stop participating in some of his activities, difficulty sleeping, and a lack of appetite. He also was wo...

Effect of Jacobsen's Relaxation Technique on the Anxiety and Job Stress Nurses Caring COVID-19 Patients

BACKGROUND Infertility causes psychological and emotional tension in the couples and makes severe stress on infertile men and women. Relaxation technique is one of the methods that reduces the stress and can balance the human's emotions. This study aimed to determine the effect of relaxation on the infertile women's stress score. METHODS This was a semi-experimental and clinical trial study. ...

Background: The informal caregivers of the patients with COVID-19, who are in direct contact with patients and Coronavirus, experience many psychological issues and are prone to illness anxiety disorder. Therefore, this study was conducted with the aim of determining the effect of virtual training of Benson relaxation technique on illness anxiety disorder in the informal caregivers of the patie...
