The learning with errors (LWE) problem is one of the main mathematical foundations of post-quantum cryptography. One of the main groups of algorithms for solving LWE is the Blum–Kalai–Wasserman (BKW) algorithm. This paper presents new improvements of BKW-style algorithms for solving LWE instances. We target minimum concrete complexity, and we introduce a new reduction step where we partially reduc
Research is not merely report-writing; it also involves elements of storytelling. In this essay, we reflect on two narrative archetypes in entrepreneurship research: the stories of entrepre- neurship as a road to salvation and means to emancipation. We outline a framework to analyze research from a storytelling perspective, apply this framework to identify implicit assumptions and methodological b
Splitting the Nash single linear reservoir into two serially connected reservoirs of unequal storage coefficients (one hybrid unit) for a physically realistic response, a hybrid model is introduced for derivation of a synthetic unit hydrograph. Empirical relations are given for estimation of the two storage coefficients from known peak flow (qp) and time to peak (tp). The hybrid model with two ser
The previous supersymmetric generalization of the unitary Harish-Chandra integral prompted the conjecture that the Harish-Chandra formula should have an extension to superspaces. We prove this conjecture for the unitary orthosymplectic supermanifold UOSp(k(1)/2k(2)). To this end, we construct and solve an eigenvalue equation.
The diversity of the contributions to this volume illustrates the complexity of the challenge. Climate change is a governance problem that needs to be analysed, and addressed, at multiple levels, in multiple sectors, and with a view to multiple actors. In searching for policy options that go beyond current negotiations, the contributions thus addressed issues as diverse as international carbon mar
Gaussian models are frequently used for road profiles. However, these models are often only valid for short sections of the road. Here we present a comprehensive approach to describe various aspects of road surface/elevation by using extensions of Gaussian models arising from random gamma distributed variances. These random variances result in the Laplace distribution and thus we refer to the so d
This report focuses on the use of egress models to assess the optimal strategy in the case of total evacuation in high-rise buildings. A model case study made of two identical twin towers linked with two sky-bridges at different heights has been simulated. The towers are 50 floor high-rise buildings including both vertical and horizontal egress components, namely stairs, occupant evacuation elevat
Ukraine has significant potential for bioenergy. Biomass can supply 1 EJ/year or 18% in the country’s energy balance. The major part of this is formed by agricultural residues and energy crops. Annually nearly 175 PJ can be derived from straw, which is currently not used elsewhere. At present the biofuels sector in Ukraine is not established although a number of initiatives have emerged. Biomass s
The hippocampal formation has long been suggested to underlie both memory formation and spatial navigation. We discuss how neural mechanisms identified in spatial navigation research operate across information domains to support a wide spectrum of cognitive functions. In our framework, place and grid cell population codes provide a representational format to map variable dimensions of cognitive sp
The present invention relates to peptides derived fromapolipoprotein A-I (apoA-I) and their use for treatment or prevention ofdiseases and disorders associated with hyper-glycaemia.
Många medarbetare och chefer i offentlig sektor vittnar om hur detaljstyrning, överdriven formbundenhet och felriktad mätning hindrar dem från att göra ett gott arbete. De upplever att verksamheten styrs och leds med fjärrkontroll och med bristande lyhördhet för behoven längst ut i styrkedjan. Forskningen pekar i samma riktning. Det här leder inte bara till minskad motivation och arbetsglädje, uta
