Due to the complexity of clinical breast cancer imaging systems, their validation and optimization are challenging tasks, which require both preclinical and clinical studies. This is particularly true for systems used in breast cancer screening due to the low prevalence of disease in a screening population. Validation for screening requires clinical trials involving very large numbers of volunteer
In this paper we present a new algorithm for the recovery of the initial state of a linear feedback shift register when a noisy output sequence is given. Our work is focussed on the investigation of the asymptotical behaviour of the recovery process rather than on the construction of an optimal recovery procedure. Our results show the importance of low-weight checks and show also that the complexi
Rubus "firmus" is a very rare plant in Norway; it is only known from a 500 m long coastal strip nearthe sea- shore in Grimstad, Aust-Agder fylke. The identity of the name R. firmus is obscure, and it is not known whether the original plant is a species or a hybrid; we do not accept this name as correct for the Norwegian plant. The Norwegian plants are not very homogeneous and have the chromosome n
Market frictions, such as imperfect information or hassle costs, may reduce benefits from market incentives in healthcare settings. We use data from two randomised policy interventions in a Swedish region, which improved the access to provider information and reduced the switching costs of one percent of the adult population and of a sample of new residents. We examine the effects of the intervent
In the years 1941–1948, thousands of people escaped across the Baltic Sea fromeastern Europe to Sweden, primarily from the Baltic states but also from theUSSR. On the basis of newly declassified Soviet correspondence throughencrypted cables between the Soviet foreign ministry and the Soviet legationin Stockholm for the years 1944–1947, this article addresses the Soviet-Swedishdiplomatic negotiatio
States in neutron-rich s-d shell nuclei were populated in the reaction of a 14C beam at Elab = 22 MeV on a 14C target. Coincidences between γ rays and either other γ rays or light charged particles were measured. γ rays in coincidence with protons established levels at 66.8, 1730, 1823, and 2219 keV in 27Na. The states are compared with calculations based on the s-d shell model and the cranked Nil
Phase retrieval is a numerical procedure concerned with the recovery of a complex-valued signal from measurements of its amplitude. We describe a generalization of this method for multi-wavelength data acquired in a coherent diffractive imaging experiment. It exploits the wavelength-dependent scaling of the support domain to recover separate reconstructions for each wavelength, providing new possi
