We consider the problem of outsourcing computation on data authenticated by different users. Our aim is to describe and implement the simplest possible solution to provide data integrity in cloud-based scenarios. Concretely, our multi-key linearly homomorphic signature scheme (MKLHS) allows users to upload signed data on a server, and at any later point in time any third party can query the server

This report aims at presenting basic knowledge on bridge scour and the processes governing its evolution as well as summarizing the most common formulas used to calculate scour depth at bridges. Design procedures concerning bridge scour in several different countries are also discussed, including United States, Australia, and the United Kingdom. The situation in Sweden with regard to bridge scour

This open access book describes methods of mortality forecasting and discusses possible improvements. It contains a selection of previously unpublished and published papers, which together provide a state-of-the-art overview of statistical approaches as well as behavioural and biological perspectives. The different parts of the book provide discussions of current practice, probabilistic forecastin

Anxiety is a natural emotional response to stress, fear, or danger. Then, it is no wonder why some are experiencing anxiety in the face of the climate crisis. Although not a clinical diagnosis, climate anxiety – and related terms like eco-anxiety, ecological grief, and solastalgia – describes the distress, grief, or anger caused by environmental destruction occurring now, or presumed to occur in t

This book explores how the concept or urban experimentation is being used to reshape practices of knowledge production in urban debates about resilience, climate change governance, and socio-technical transitions.With contributions from leading scholars, and case studies from the Global North and South, from small- to large-scale cities, this book suggests that urban experiments offer novel modes

Fruit-feeding pteropodid bats roost under varying light conditions. Some roost in trees with high exposure to daylight (> 1000 lx), while others roost in dark caves (< 0.1 lx). To understand the effect of ambient light intensity and moon phase on flight activity, we examined flight times across five lunar cycles in three pteropodid species whose roosts differ in daylight exposure. We found signifi

OBJECTIVE: To establish clear priorities for the care of patients with acquired hemophilia A (AHA) by proposing 10 key principles of practical, holistic AHA management.METHOD: These principles were developed by the Zürich Haemophilia Forum, an expert panel of European hemophilia specialists comprising physicians and nursing and laboratory specialists.RESULTS: The 10 proposed principles for AHA car

Increasing impacts from climate change have prompted international calls for the development of synergetic mitigation and adaptation policies and measures. While cities are seen as key actors in the implementation of related actions, there is a lack of scientific knowledge on the organizational conditions required to achieve this in practice. Our paper addresses this gap. Specifically, we assess t

To avoid harm to the public and the environment, lost ionizing radiation sources must be found and brought back under the regulatory control as soon as possible. Usually, mobile gamma spectrometry systems are used in such search missions. It is possible to estimate the position and activity of point gamma sources by performing Bayesian inference on the measurement data. The aim of this study was t

"This new edition of Lund and Learning paints a picture of Lund as a city of learning, from the age of the medieval bishops to the university reforms of the 1990s."

Tack vare kikare, teleskop och spektroskop har vi kunnat blicka längre ut i Universum än som någonsin hade varit möjligt med bara ögonen. På samma sätt finns det ett helt Universum åt andra hållet. Bland celler, molekyler, ände ner till atomer. Men nere i atomvärlden är det inte teleskop som behövs. Nej, där tar vi hjälp av de fiffiga små neutronerna själva.Thanks to binoculars, telescopes and spectroscopes, we have been able to look further out into the Universe than would ever have been possible with the naked eye. In the same way, there is a whole Universe in the other direction. Among cells, molecules, and down to atoms. But down in the nuclear world, telescopes are not needed. No, there we take the help of the small neutrons themselves.

Experimental studies are carried out to investigate the heat transfer performance of six different arrangements of truncated ribs in internal cooling channel by fixing the Reynolds number. The convective heat transfer mechanisms of the considered cases are detailed and analyzed based on the fluid flow characteristics by using three dimensional numerical simulations. The results show that among six

In this release note we describe the 1.2 update to NLOX, a computer program for calculations in high-energy particle physics. New features since the 1.0 release and other changes are described, along with usage documentation. New version program summary: Program title: NLOX Developer's repository link: http://www.hep.fsu.edu/~nlox Licensing provisions: CC BY NC 3.0 Programming language: C++. Fortr
