Low rank approximation is a commonly occurring problem in many computer vision and machine learning applications. There are two common ways of optimizing the resulting models. Either the set of matrices with a given rank can be explicitly parametrized using a bilinear factorization, or low rank can be implicitly enforced using regularization terms penalizing non-zero singular values. While the for
Modes of climate variability affect global and regional climates on different spatio-temporal scales, and they have important impacts on human activities and ecosystems. As these modes are a useful tool for simplifying the understanding of the climate system, it is crucial that we gain improved knowledge of their long-term past evolution and interactions over time to contextualise their present an
Nappes of continental outer and outermost margin affinities (Middle Allochthon) were transported from locations west of the present Norwegian coast and thrust eastwards onto the Baltoscandian foreland basin and platform. They are of higher metamorphic grade than underlying thrust sheets and most are more penetratively deformed. These allochthons are treated here in three groups. The lower thrust s
Artikeln undersöker eurons konsekvenser för integration och tillväxt i Östersjöregionen (Polen, Litauen, Lettland, Estland, Finland och Sverige). Efter Sovjetunionens sammanbrott har de baltiska staterna och Polen snabbt hämtat in på Västeuropa. Den globala finanskrisen blev ett kraftigt bakslag för de förra, men i mindre utsträckning för Polen. Penningpolitiken har gjort skillnad: den polska zlotWhich have been the consequences of the euro for integration and economic performance in the Baltic Sea region? After the collapse of the Soviet Union, the three Baltic states and Poland have been rapidly catching-up with Western Europe. The Great Recession becamea great setback for the former, while less so for Poland. A difference is the monetary policy: the Polish zloty depreciated in t
U-Pb geochronology on baddeleyite is a powerful technique that can be applied effectively to chronostratigraphy. In southern Africa, the Kaapvaal Craton hosts a well-preserved Mesoarchean to Paleoproterozoic geological record, including the Neoarchean Ventersdorp Supergroup. It overlies the Witwatersrand Supergroup and its world-class gold deposits. The Ventersdorp Supergroup comprises the Klipriv
Experiences of cancer diagnosis are changing in light of both the increasingly technological-clinical diagnostic processes and the socio-political context in which interpersonal relations take place. This has raised questions about how we might understand patient–doctor relationship marked by asymmetries of knowledge and social capital, but that emphasise patients’ empowered choices and individual
Introduction Studies about machinery equipment investment have a long tradition in economics and economic history. Since the analysis of the Industrial Revolution and the growth studies of the twentieth century, there are indications that economic growth of countries has a strong nexus with investment in capital formation and speci cally, with the machinery equipment investment. However, in the ca
In this work a method was developed for characterisation of commercially available polymers consisting of mixtures of substituted cellulose and starch. Selective hydrolysis with specific enzymes was used to achieve separation of the two polymers in the mixture. Enzymes hydrolysing (1 -> 4)-alpha-D and (1 -> 6)-alpha-D-glycosidic bonds were used for the starch part and enzymes hydrolysing (1 -> 4)-
We review studies of the implementation of human papillomavirus (HPV) vaccination programmes in developed and developing countries. The review spans the period from establishment of long-term vaccine efficacy follow-up studies, operational research on issues of vaccine preparedness, and relevant predictive modelling studies during the pre-licensure phase to plans of phase IV effectiveness trials,
The bacterial flora of the intestine and the bacteria found in liver, mesenteric lymph nodes, portal and arterial blood after D-galactosamine-induced liver injury, with and without pretreatment with Lactobacillus plantarum DSM 9843, were studied in the rat. Dominating representatives were identified to species level by 16S rDNA sequencing and typed by randomly amplified polymorphic DNA (RAPD) and

Kainate-induced seizures result in hippocampal neurodegeneration and spatial learning deficits in rodents. Previous studies show that rofecoxib, a selective cyclooxygenase-2 inhibitor, protects against kainate-induced hippocampal cell death 3 days after seizures. Our aim was to determine whether rofecoxib attenuates visuospatial learning deficits and late neuronal death after kainate-induced seizu
Recent evidence suggested a weak relationship between alcohol consumption and pancreatic cancer (PC) risk. In our study, the association between lifetime and baseline alcohol intakes and the risk of PC was evaluated, including the type of alcoholic beverages and potential interaction with smoking. Within the European Prospective Investigation into Cancer and Nutrition (EPIC) study, 1,283 incident
