Quantum states extended over a large volume in phase space have oscillations from quantum interferences in their Wigner distribution on scales smaller than variant Planck's over 2pi [W. H. Zurek, Nature (London) 412, 712 (2001)]]. We investigate the influence of those sub-Planck-scale structures on the sensitivity to an external perturbation of the state's time evolution. While we do find an ac...

changed and modernised practice in recent years. But this has wider implications. When you submit research for publication your contribution to the study and to the manuscript and that of each author must be outlined. Rather than just stating that the study has been by a Local Ethics Committee you need to provide proof. Institutional Research & Development departments have also come under scrut...

Introduction: Mitral valve insufficiency in adults is often a complication of ischemic heart disease. Coronary artery bypass grafting (CABG) is performed as a strategy for the treatment of coronary artery disease. The aim of this study was to evaluate mitral regurgitation (MR) before and after CABG. Materials and Methods: This Experimental study was condu...

background: several competing geometric and hemodynamic factors are suggested as contributing mechanisms for functional mitral regurgitation (mr) in heart failure patients. we aimed to study the relationships between the severity of mr and the qrs duration and dyssynchrony markers in patients with ischemic or dilated cardiomyopathy. methods: w e prospectively evaluated 251 heart failure patient...

In this paper the performance of Artificial Neural Networks (ANNs) and Adaptive Neuro- Fuzzy Inference Systems (ANFIS) in simulating the inverse dynamic behavior of Magneto- Rheological (MR) dampers is investigated. MR dampers are one of the most applicable methods in semi active control of seismic response of structures. Various mathematical models are introduced to simulate the dynamic behavi...

I was only a child when Dr Carleton Gajdusek, Michael Alpers and Shirley Lindenbaum conducted research on kuru in the South Fore. They patrolled around the villages and saw how many of our people were dying of kuru and the number of orphans in our villages. My late brother, Mr Animo Kaguya, was the only member of our family involved in the early research on kuru; he assisted in carrying equipme...
