We give an expression for the Garsia entropy of Bernoulli convolutions in terms of products of matrices. This gives an explicit rate of convergence of the Garsia entropy and shows that one can calculate the Hausdorff dimension of the Bernoulli convolution νβ to arbitrary given accuracy whenever β is algebraic. In particular, if the Garsia entropy H(β) is not equal to log(β) then we have a finite t
This paper presents the results of a qualitative study of user behaviour on the World-Wide Web. Eight participants were filmed whilst performing user-defined tasks and then asked to review the video-taped session during prompted recall. This data forms the basis for a series of descriptions of user behaviour and the postulation of a number of underlying cognitive mechanisms. Our results indicate t
Popular Abstract in Swedish Denna avhandling syftar till att ge en översikt över cirka hundra år av europeisk intellektuell historia som lyfter fram nya aspekter av de klassiska tänkarna. Analysen av de fyra filosoferna Thomas Hobbes, John Locke, David Hume och Charles de Montesquieu syftar till att belysa en generell historisk process, nämligen hur den moderna människosynen växer fram i Europa. E
Infectious and parasitic agents (IPAs) and their associated diseases are major environmental stressors that jeopardize bee health, both alone and in interaction with other stressors. Their impact on pollinator communities can be assessed by studying multiple sentinel bee species. Here, we analysed the field exposure of three sentinel managed bee species (Apis mellifera, Bombus terrestris and Osmia
We discuss the associated cc¯ and l+l- pairs production in ultraperipheral heavy-ion collisions at high energies. Such a channel provides a novel probe for double-parton scattering (DPS) at small x enabling one to probe the photon density inside the nucleus. We have derived an analog of the standard central pp pocket formula and studied the kinematical dependence of the effective cross section. Ta
Introduction: Heterogeneity in composition and spatial configuration of landscape elements support diversity and abundance of flower-visiting insects, but this is likely dependent on taxonomic group, spatial scale, weather and climatic conditions, and is particularly impacted by agricultural intensification. Here, we analyzed the impacts of both aspects of landscape heterogeneity and the role of c
This dataset features geocoding for the complete population of:Landskrona at the block-level from 1904-1967;Landskrona at the address-level from 1939-1967; andKävlinge at the block-level from 1939-1967.All these populations are part of the Scanian Economic-Demographic Database (SEDD). SEDD is a high-quality, longitudinal database that covers five Scanian parishes: Halmstad, Hög, Kågeröd, Kävlinge,
Abstract : We present the first a priori derivation of a many-body theory for EXAFS with clearly defined approximations and with final expressions which are feasible for quantitative evaluations. We conclude that the conventional EXAFS expression should be complemented with a term that crudely is the main term, energy-shifted and scaled down by a factor of order 0.2-0.3. Further the f-factors depe
Det är viktigt att förstå att de insatser som görs för att förbättra skolan alltid baseras på både kunskapssyn och människosyn. Att kräva att alla elever får stöd i tid och har engagerade och kunniga lärare visar på en samtida kunskaps- och människosyn, grundad i forskning om lärande och barns utveckling.
Nominal classification is a robust feature in many Amazonian languages, and aspects of these systems offer significant challenges to our broader conception of the phenomenon. Yet a clear characterization of Amazonian classification systems must be firmly grounded in detailed descriptive analysis on one hand, and in a principled definition of classification as a typological category on the other –
