Macro-Finance Determinants of the Long-Run Stock-Bond Correlation: The DCC-MIDAS Specification

We investigate the long-run stock-bond correlation using a novel model that combines the dynamic conditional correlation model with the mixed-data sampling approach. The long-run correlation is affected by both macro-finance variables (historical and forecasts) and the lagged realized correlation itself. Macro-finance variables and the lagged realized correlation are simultaneously significant in

Arithmetic reduction of adder leakage in nanoscale CMOS

in today’s technology generations, e.g. 90 and 65 nm, the static power consumption becomes a major contributor to the total power consumption. It is therefore important to consider all abstraction levels to reduce this power. This paper focuses on the arithmetic level and shows a methodology for a substantial reduction of the static power consumption. Both the dynamic and static power consumption

Kossor, kaffe och soja

När Amazonas regnskog huggs ner och den brasilianska Cerrado-savannen odlas upp med soja och kaffe och foder till köttproduktion så hamnar notan för klimatutsläppen på Brasiliens konto. Är det rimligt, med tanke på att mycket av köttet och de andra jordbruksprodukterna exporteras till Europa, USA och Kina? Vem ska stå för klimatutsläppen från en förändrad markanvändning, när varor som produceras p

Reflexiv fältarkeologi? Återsken av ett seminarium.

Hur undviker vi att fastna i gamla "sanningar"? Hur ställer vi frågor som möjliggör överraskande svar? Hur skapar vi ett arbetsklimat som stimulerar reflektion? Detta är några av de frågor som diskuteras i "Reflexiv fältarkeologi?". I boken medverkar 33 författare varav flertalet är verksamma inom uppdragsarkeologin. Boken tar pulsen på dagens svenska fältarkeologi och fångar åsikter och erfarenhe

Intrinsically Proton-Conducting Benzimidazole Units Tethered to Different Polymer Chain Architectures

Popular Abstract in Swedish Protontransport är en fundamental process som finns i många naturliga system, liksom i många tekniska applikationer, såsom bränsleceller, smarta fönster och olika typer av sensorer. Bränslecellsteknologi anses vara miljövänlig eftersom bränsleceller inte begränsas av Carnot-cykeln och omvandlar effektivt kemisk energi till elektrisk energi som sedan kan användas till atProton transport is a fundamental process that can be found in many systems in nature, as well as in technical devices, such as fuel cells, electrochromic devices and various types of sensors. Fuel cell technology is considered as environmentally friendly because fuel cells are not limited by the Carnot cycle, and efficiently converts chemical energy into electrical energy which can be used for po

Elicitor-induced formation of secondary products in plant cell cultures. Production of benzophenanthridine alkaloids in Eschscholtzia californica Cham. and hydroxycinnamic acid tyramides in Nicotiana glutinosa L.

Biotic and abiotic elicitors induce biosynthesis of secondary metabolites (phytoalexins) as a defense against pathogenic organisms in plants. The use of cell suspension cultures in combination with elicitors offer excellent experimental model systems for studies on various elicitor-induced responses of plant tissues. Various elicitors were added to cell suspension culture of Eschscholtzia californ

Reconstruction and visualization of equivalent currents on a radome using an integral representation formulation

In this paper an inverse source problem is investigated. The measurement set-up is a reflector antenna covered by a radome. Equivalent currents are reconstructed on a surface shaped as the radome in order to diagnose the radome's interaction with the radiated field. To tackle this inverse source problem an analysis of a full-wave integral representation, with the equivalent currents as unknowns, i

Layover Solutions in Multibaseline InSAR using Interpolated Arrays

This work deals with the problem of direction of arrival estimation of interferometric synthetic aperture radar (InSAR) signals in presence of layover. The focus here is on realistic acquisition systems with a low number of phase centres and nonuniform array geometry. An interpolated array approach is proposed, in order to apply spectral estimation techniques designed for uniform linear arrays. In
