Long-lived coherences have been observed in various biological complexes and their origin is debated. We used polarization-controlled 2D electronic spectroscopy to reveal a photophysical process of coherence shift, explaining coherences in bacterial reaction centers.

Time-resolved XPS is used to monitor charge carrier dynamics in bare and dyesensitized ZnO nanoparticle films upon sub-bandgap excitation. Results are discussed in the context of impurity-related bandgap states and electron transfer from the chromophore.

The line shape of an absorption line from molecular oxygen enclosed in the pores of a ceramic material has been studied at different temperatures. By evaluating the line width it is feasible to extract temperature information of the gas inside porous scattering materials.

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
