Many of the finalists selected for the NIST post-quantum cryptography project are lattice-based and rely on a Learning With Errors problem (LWE). To solve such a problem, it is possible to implement a primal attack or a dual attack. In this context, Guo and Johansson as well as the MATZOV center have both proposed an improved dual attack against several NIST lattice candidates. The goal of this t
Methodology: The study is conducted as a qualitative research, where empirical data has been collected through semi-structured interviews with Swedish new ventures. The study does further take an abductive approach in terms of the theoretical viewpoint and research perspective. Theoretical perspective: The study is based on previous research about the early phases of new ventures, the importance
This essay examines the arguments laid forth by the European Union regarding restrictive measures imposed on the Russian Federation, concerning the illegal annexation of the Crimean peninsula, in an effort to evaluate and classify these grounded in the Toulmin model of arguments and Giumelli’s concepts of Con-straining, Coercing and Signalling. By assessing the arguments made by four EU institutio
The field synergy principle has three criteria to qualitatively describe the essence of single-phase convective heat transfer enhancement. However, in practice these criteria are difficult to be applied to convective heat transfer analysis, because there are no corresponding indicators available to quantitatively describe them. Therefore, a unified formula for the field synergy principle was devel
Objectives: To investigate associations between sexual identity and low leisure-time physical activity (LTPA). Study design: Cross-sectional study. Methods: The 2012 public health survey was conducted with a postal questionnaire in southern Sweden with 28,029 respondents, aged 18–80 years. Analyses were conducted with logistic regressions. Results: The prevalence of low LTPA among men and women we
We conduct what we believe to be the most methodologically rigorous study of mood effect in the field so far to measure its economic impact and address shortcomings in the existing literature. Using a large dataset containing over 46 million car inspections in Sweden and England in 2016 and 2017, we study whether inspectors are more lenient on days when their mood is predicted to be good, and if c
In this paper, the matched reassigned spectrogram is expanded into a novel matched phase reassignment (MPR) method based on the reassigned cross-spectrogram. It is shown that for two phase synchronized oscillating transient signals, the method gives perfect time-frequency (TF) localization. The MPR is thereby a TF local measure of phase synchronization and can also be used to measure phase differe
PURPOSE: Pre-clinical studies have shown that ex vivo non-ischemic heart preservation (NIHP) method can be safely used for 24 hours. This state-of-the-art method has never been applied on humans. The primary objective of the study was to evaluate the efficacy and safety of the NIHP method on early and late human heart allograft function compared with static cold storage (SCS). METHODS: We perfor
We evaluate the distribution of waiting times between electrons emitted by a driven mesoscopic capacitor. Based on a wave packet approach we obtain analytic expressions for the electronic waiting time distribution and the joint distribution of subsequent waiting times. These semi-classical results are compared to a full quantum treatment based on Floquet scattering theory and good agreement is fou
The electrical charge limit of crystallizing sodium chloride droplets has been studied. Moderately charged sodium chloride solution droplets were dried to highly charged residual particles. The charge limit was found to be near the Rayleigh charge limit for saturated sodium chloride droplets of the same size as the residual particle. The charge loss was not found to affect the particle size to a d
We summarise the main features of VINCIA's antenna-based treatment of QCD initial- and finalstate showers, which includes iterated tree-level matrix-element corrections and automated evaluations of perturbative shower uncertainties. The latter are computed on the fly and are cast as a set of alternative weights for each generated event. The resulting algorithm has been made publicly available as a
Despite academic advances in PID controller design and development of automatic tuning procedures, there are still many PID controllers that are badly tuned, or not even tuned at all, in process industry. There are several reasons for this, but one major reason is that it is considered too time consuming to use current PID controller tuning methods. This paper presents a new tuning method that is
We consider the reliability function of Markov channels with feedback and variable length channel codes. We extend Burnashev's [3] classic result to this case and present a single letter characterization for the reliability function.
We identify three semiclassical parameters in the QCD Dirac operator. Mutual coupling of the different types of degrees of freedom (translational, colour and spin) depends on how the semiclassical limit is taken. We discuss various semiclassical limits and their potential to describe spectrum and spectral statistics of the QCD Dirac operator close to zero virtuality. (c) 2006 Elsevier Inc. All rig
Ban and coworkers at ETH are step-by-step widening the perspective of the actions on the ribosome (Bingel-Erienmeyer et al., 2008). The last one in the series is the localization of the binding site of peptide deformylase at the mouth of the polypeptide exit tunnel.
We consider the stationary Ginzburg–Landau equations in Rd, d=2,3. We exhibit a class of applied magnetic fields (including constant fields) such that the Ginzburg–Landau equations do not admit finite energy solutions.
