Alzheimer's disease is characterized by hippocampal atrophy. Other factors also influence the hippocampal volume, but their interactive effect has not been investigated before in cognitively healthy individuals. The aim of this study is to evaluate the interactive effect of key demographic and clinical factors on hippocampal volume, in contrast to previous studies frequently investigating these fa
Partially premixed combustion using gasoline-like fuels on compression ignition engines shows great potentials to break the soot-nitrogen oxides trade off and reduce both emissions simultaneously. By simply adjusting the dilution strategies and injection events, the control of partially premixed combustion is relatively easier compared to other low-temperature combustion concepts. However despite
The impact of climate variability on water demand and availability in drylands is substantial. Establishing methods to analyse precipitation (P) and evapotranspiration data sets may generate useful tools that assist in drought recognition and regional variations therein. The authors developed an index that simultaneous integrates both these variables in climate variability analysis. This study pro
This chapter provides an overview of the main concepts in mechanobiology and touches upon the experimental models that are most frequently used to study mechanobiology on a cell and tissue level. It focuses on the use of computational techniques and algorithms to simulate mechanobiological processes, and their prospective potential in clinical applications. It covers how computational algorithms h
In this paper I discuss the work of two French authors who advocate a "scientific" exegesis of sacred scriptures: physician Maurice Bucaille (1922-1998) and religious leader Claude Vorilhon (alias Raël, b. 1946). Bucaille argues that the Qur'an's divine origin is demonstrated by its accuracy about natural phenomena and "scientific facts," whereas the Bible does not stand up to "scientific" examina
While previous research examines how institutions matter for general life satisfaction and how specific institutions embodying equal rights for gay people matter for the life satisfaction of gays, we combine these two issues to analyze how the latter type of institutions relates to general life satisfaction. The question is how people in general are affected by laws treating everyone equally irres
The way we use computers and mobile phones today requires large amounts of processing of data streams. Examples include digital signal processing for wireless transmission, audio and video coding for recording and watching videos, and noise reduction for the phone calls. These tasks can be performed by stream programs—computer programs that process streams of data. Stream programs can be composed
This is the story of how a large research facility of broad European and global interest, the European Spallation Source (ESS), ended up in the small university town of Lund in Sweden. This happened in spite of the fact that a number of influential European countries were at one time or another competitors to host the facility. It is also a story about politics which attempts to illustrate how clo
Här presenteras det nystartade projektet Flerspråkiga praktiker i engelskundervisningen, finansierat av Vetenskapsrådet, samt forskning om flerspråkighet som ligger till grund för projektet. Vi kommer att undersöka hur och varför lärare och elever använder andra språk än engelska i engelskundervisningen. Vilken betydelse har användningen av elevers starkaste språk för deras lärande och inkludering
In this essay, I aim to complement social identity theory (SIT) concepts of identification with insights from psychoanalysis to address three problematic aspects: (a) SIT emphasizes cognition and often neglects emotions, (b) emotions—if mentioned —are primarily positive, and (c) SIT-based concepts can be used to inspire simplified ideas of identification management. I argue that psychoanalytic ins
The effects of injection pressure and swirl ratio on the in-cylinder soot oxidation are studied using simultaneous PLIF imaging of OH and LII imaging of soot in an optical diesel engine. Images are acquired after the end of injection in the recirculation zone between two adjacent diesel jets. Scalars are extracted from the images and compared with trends in engine-out soot emissions. The soot emis
The adaptive subspace detector in system-dependent clutter background (SDC-ASD) is proved to be able to improve the detection performance for deterministic target detection in the authors' previous study. However, the exact performance of the SDC-ASD for fluctuating target detection is still unknown. In this study, with the aid of matrix decomposition theory, the analytical performance of the SDC-
We develop fixed-point algorithms for the approximation of structured matrices with rank penalties. In particular we use these fixed-point algorithms for making approximations by sums of exponentials, i.e., frequency estimation. For the basic formulation of the fixed-point algorithm we show that it converges to the solution of a related minimization problem, namely the one obtained by replacing th
