Ridesharing is revolutionizing the transportation industry in many countries. Yet, the state of the art is based on heavily centralized services and platforms, where the service providers have full possession of the users’ location data. Recently, researchers have started addressing the challenge of enabling privacy-preserving ridesharing. The initial proposals, however, have shortcomings, as some
Multi-Key Homomorphic Signatures (MK-HS) enable clients in a system to sign and upload messages to an untrusted server. At any later point in time, the server can perform a computation C on data provided by t different clients, and return the output y and a short signature σC,y vouching for the correctness of y as the output of the function C on the signed data. Interestingly, MK-HS enable verifie
OBJECTIVES: To analyse the association between ABO blood group and aortic disease using data on blood donors and transfused patients from Sweden. DESIGN: This was a retrospective study using data from the Swedish portion of the Scandinavian Donations and Transfusions Database. The association between ABO blood group and aortic disease was analysed using log-linear Poisson regression models and pre
An emerging direction for authenticating people is the adoption of biometric authentication systems. Biometric credentials are becoming increasingly popular as a means of authenticating people due to the wide range of advantages that they provide with respect to classical authentication methods (e.g., password-based authentication). The most characteristic feature of this authentication method is
In biometric authentication protocols, a user is authenticated or granted access to a service if her fresh biometric trait matches the reference biometric template stored on the service provider. This matching process is usually based on a suitable distance which measures the similarities between the two biometric templates. In this paper, we prove that, when the matching process is performed usin
AIM Enterococci cause 2-11% of all prosthetic joint infections (PJI) and are generally considered difficult to treat. However, study-results are not consistent. In this study we present a population-based case series of 55 cases with enterococcal PJI, investigating treatment and outcome, as well as describing the affected patient population regarding demography and co-morbidities. METHODS We ident
How do you take a reliable measurement of a material whose microstructure is random? When using wave scattering, the answer is often to take an ensemble average (average over time or space). By ensemble averaging we can calculate the average scattered wave and the effective wavenumber. To date, the literature has focused on calculating the effective wavenumber for a plate filled with particles. On
Offentliga anklagelser leder ofta till kontrovers. Anklagelser har studerats utifrån hur de ger upphov till vissa typer av försvar, liksom hur en anklagande part kan övertyga om skuld och förstärka uppfattningen om anstötligheten i en handling. Vi undersöker ett satirprogram som strategisk handling, med särskilt fokus på hur dess anklagelses retoriska struktur strategiskt möjliggör vissa gensvar o
In recent years, Large Scale Land Acquisitions (LSLA), direct land tenure changes have been gaining momentum in developing countries. In this study, we evaluate the potential extent to which agricultural land deals in Africa are able to address the host countries’ food security needs, a commonly cited motivation for their establishment. First, we develop a framework to evaluate the priority food s

High hyperdiploid acute lymphoblastic leukemia (ALL) is one of the most common malignancies in children. The main driver event of this disease is a nonrandom aneuploidy consisting of gains of whole chromosomes but without overt evidence of chromosomal instability (CIN). Here, we investigated the frequency and severity of defective sister chromatid cohesion—a phenomenon related to CIN—in primary pe
The main aim of this paper is to explore how these 3D printing enthusiasts make sense of their 3D printing activities online and offline, and how these activities can be explained in terms of the theoretical concepts user innovation and user entrepreneurship. This paper builds on an in-depth interview study and reveals four ideal types (Halkier, 2011) of 3D printing enthusiasts: Entrepreneurial, h
Aims: Huntington disease (HD) is a fatal neurodegenerative disorder with no disease-modifying treatments approved so far. Ongoing clinical trials are attempting to reduce huntingtin (HTT) expression in the central nervous system (CNS) using different strategies. Yet, the distribution and timing of HTT-lowering therapies required for a beneficial clinical effect is less clear. Here, we investigated
Proportionality reasoning is an established form of legal argumentation under international human rights law, employed by the European Court of Human Rights and the United Nations (UN) human rights treaty bodies alike. However, relatively little has been written about its precise role and content in relation to equality norms. Proportionality scholars tend to draw on other examples to demonstrate
