There is a significant interest in scene reconstructionfrom underwater images given its utility for oceanic researchand for recreational image manipulation. In this paperwe propose a novel algorithm for two view camera motionestimation for underwater imagery. Our method leveragesthe constraints provided by the attenuation propertiesof water and its effects on the appearance of the color todetermin
We describe the main features and preliminary evaluation of Positive Technology, a free mobile platform for the self-management of psychological stress (http://positiveapp.info/). The mobile platform features three main components: (i) guided relaxation, which provides the user with the opportunity of browsing a gallery of relaxation music and video-narrative resources for reducing stress; (ii) 3D
In this paper we argue for an analysis of Object Shift in Mainland Scandinavian in which the shifted word order is the result of a prosodic repair to enable weak pronoun incorporation. We observe that varieties with optional OS also have a tone accent contrast. We argue that the in-situ word order is licensed in these dialects because tonal accent creates a prosodic domain licensing the incorporat
The prospects of domestic punishment might compel leaders responsible for the initiation of the war to continue fighting until they achieve favorable war outcomes (Croco 2011, 2015). As applied to war duration, this logic implies that ‘culpable’ leaders do not have incentives to end a war that will bring defeat. This paper argues that leaders can escape this dilemma by blaming and replacing their
Paragone is a well-known and often applied category to discuss the interrelationship of the Sister Arts. However, it does not seem to be a sufficient label to respond to the general questions raised about representation, mimesis and identity brought together in the postmodern intermedial writing of The Matisse Stories (1993), by A.S. Byatt, which was influenced by French avant-garde literature and
Background An early and accurate diagnosis of chronic heart failure is a big challenge for a general practitioner. Assessment of left ventricular function is essential for the diagnosis of heart failure and the prognosis. A gold standard for identifying left ventricular function is echocardiography. Echocardiography requires input from specialized care and has a limited access in Swedish primary h
This primer introduces a series of essays on the politics of metaphors in the digital society. It aims to uncover the hidden assumptions and concepts within our discourses of the digital, piece by piece.The current rapid social and technological change is giving rise to enormousuncertainties – and a great need for explanation and sense-making. How do weunderstand the digital society? When we talk about the future that we cannot knowand a present that we do not understand, we have no option but to use the conceptual apparatus of the past – with normative, social and economic implications. This pri
Astrocytes play an important role in glutamatergic neurotransmission, namely by clearing synaptic glutamate and converting it into glutamine that is transferred back to neurons. The rate of this glutamate–glutamine cycle (VNT) has been proposed to couple to that of glucose utilization and of neuronal tricarboxylic acid (TCA) cycle. In this study, we tested the hypothesis that glutamatergic neurotr
In ultrarelativistic heavy-ion collisions, the event-by-event variation of the elliptic flow v2 reflects fluctuations in the shape of the initial state of the system. This allows to select events with the same centrality but different initial geometry. This selection technique, Event Shape Engineering, has been used in the analysis of charge-dependent two- and three-particle correlations in Pb–Pb
Substituted arylethanols can be coupled by using a readily available Ru catalyst in a fully deoxygenative manner to produce hydrocarbon chains in one step. Control experiments indicate that the first deoxygenation occurs through an aldol condensation, whereas the second occurs through a base-induced net decarbonylation. This double deoxygenation enables further development in the use of alcohols a
Peatlands are important carbon reserves in terrestrial ecosystems. The microtopography of a peatland area has a strong influence on its carbon balance, determining carbon fluxes at a range of spatial scales. These patterned surfaces are very sensitive to changing climatic conditions. There are open research questions concerning the stability, behaviour and transformation of these microstructures,
