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
To survive organisms must defend themselves against pathogens. Classical Major Histocompatibility Complex (MHC) genes play a key role in pathogen defense by encoding molecules involved in pathogen recognition. MHC gene diversity influences the variety of pathogens individuals can recognize and respond to and has consequently been a popular genetic marker for disease resistance in ecology and evolu
During the interwar period, there was a surge in cultural diplomacy efforts in Europe. This article investigates the role of cultural diplomacy within the Swedish film society movement, focusing particularly on Lund Film Society’s travels abroad during the 1930s: to Nazi-Germany in 1935 and in 1938 respectively, as well as to the Soviet Union in 1936. Through international exchange, Lund Film Soci
In stochastic modeling of infectious diseases, it has been established that variations in infectivity affect the probability of a major outbreak, but not the shape of the curves during a major outbreak, which is predicted by deterministic models (Diekmann et al., 2012). However, such conclusions are derived under idealized assumptions such as the population size tending to infinity, and the indivi
The #FridaysForFuture climate protests mobilized more than 1.6 million people around the globe in March 2019. Through a school strike, a new generation has been galvanized, representing a historical turn in climate activism. This wave of climate protest mobilization is unique in its tactics, global scope and appeal to teenage school students. Media coverage of these protests and high-level nationa
As part of aiming towards a non-smoking hospital environment, staff at a Copenhagen university hospital were offered participation in a differentiated smoking cessation programme. This consisted of lectures, group therapy, follow-up visits and individually tailored nicotine replacement therapy free-of-charge for six weeks. Three hundred and seventy-four employees started the programme, with 353 co
Due to the migration megatrend, efficient and effective second-language acquisition is vital. One proposed solution involves AI-enabled conversational agents for person-centered interactive language practice. We present results from ongoing action research targeting quality assurance of proprietary generative dialog models trained for virtual job interviews. The action team elicited a set of 38 re
This article is a response to Steven Enderlein on the translation of Rom 3:23 and its implications for the πίστις Χριστοῦ debate. While affirming Enderlein's suggestion that the verb ὑστερέω is better understood as “lack” rather than “fall short,” we argue against his conclusions (1) that this translation leads to a subjective genitive reading of πίστις Χριστοῦ in Rom 3:22, 26; and (2) that the ve
A brief period of sublethal cerebral ischemia, followed by several days of recovery, renders the brain resistant to a subsequent lethal ischemic insult, a phenomenon termed ischemic preconditioning or tolerance. Ischemic tolerance was established in the rat two-vessel occlusion model of ischemia, induced by occlusion of both carotid arteries in combination with hypotension. Ischemic preconditionin
A short period of sublethal preconditioning ischemia (3 min) followed by two days of reperfusion provides almost complete protection against ischemic cell death induced by a second (9 min) lethal ischemic episode. Here, we have investigated the extracellular signal-regulated protein kinase kinase and extracellular signal-regulated protein kinase, two kinases known to activate gene transcription an
The protective effect of the α2-receptor antagonist idazoxan against neuronal damage in the neocortex and in the hippocampal CA1 region was studied in rats exposed to 10 min of incomplete forebrain ischemia. When administered i.v. immediately after ischemia (0.1 mg/kg) and subsequently for 6 h (10 μg/kg/min), idazoxan significantly reduced neuronal damage in the hippocampus (from 84 to 26%) and in
Mellan åren 1955 och 1957 utförde Märta Strömberg (sedermera professor i arkeologi) och Rolf Petré (som senare blev fil. lic. i arkeologi) arkeologiska undersökningar av Vätterydsgravfältet i norra Mellby socken (L1990:1893 / Norra Mellby 1:1) ...
Climate City Contracts or CCCs are being developed in the context of a larger mission, with many stakeholders, funding, and growing momentum, hopefully providing a new force, legitimacy, and inspiration to ongoing urban climate actions. CCCs differ from current strategies for tackling climate change in cities because they are being developed in the context of the mission approach to tackle some of
Concerns over the earth’s ability to sustain itself over the long term as a consequence of human consumption of natural resources points towards sustainable development. Since a large proportion of human consumption is linked to buildings and construction, this means managing the construction process in more sustainable ways. Strategies that target greater material efficiency and which promote cir
Cosmology presents students with ideas that stimulate their curiosity and brings together various concepts from STEM that call on a variety of reasoning types across multiple representational modes, involving subtleties of spacetime relations, a variety of models and evidence requiring multiple lines of high precision observations. This study investigated high school students’ levels and types of
