Entanglement detection schemes and coherent manipulation of spin in quantum dots

Populärvetenskaplig sammanfattning:Dagens datorer har krympt i storlek i takt med den ständigt ökande kompetensen att tillverka transistorer med en anmärkningsvärd noggrannhet. Storleksskalan av nya transistorer börjar motsvara den av en handfull atomer.På denna skala dominerar kvantfysik, vilket är ett väsentligt hinder för de traditionella datorkomponenterna. Men detta innebär inte bara en begräThe work contained in this thesis deals with two closely related topics. Papers I-III deal with charge transport statistics in nanoscale devices to investigate the presence of entanglement in the constituent electrons. We identify the contributions of entangled electron pairs to the current cross-correlations as a signature of entanglement. Paper IV treats the electric control of a quantum dot bas

Microscopic origin of the charge transfer in single crystals based on thiophene derivatives : A combined NEXAFS and density functional theory approach

We have investigated the charge transfer mechanism in single crystals of DTBDT-TCNQ and DTBDT-F4TCNQ (where DTBDT is dithieno[2,3-d;2′,3′-d′] benzo[1,2-b;4,5-b′]dithiophene) using a combination of near-edge X-ray absorption spectroscopy (NEXAFS) and density functional theory calculations (DFT) including final state effects beyond the sudden state approximation. In particular, we find that a descri

Genome sequence of the pea aphid Acyrthosiphon pisum

Aphids are important agricultural pests and also biological models for studies of insect-plant interactions, symbiosis, virus vectoring, and the developmental causes of extreme phenotypic plasticity. Here we present the 464 Mb draft genome assembly of the pea aphid Acyrthosiphon pisum. This first published whole genome sequence of a basal hemimetabolous insect provides an outgroup to the multiple

Hard diffraction in Pythia 8

We present an overview of the options for diffraction implemented in the general-purpose event generator Pythia 8 [1]. We review the existing model for soft diffraction and present a new model for hard diffraction. Both models use the Pomeron approach pioneered by Ingelman and Schlein, factorising the diffractive cross section into a Pomeron flux and a Pomeron PDF, with several choices for both im

Commitment to Sustainability in Small and Medium-Sized Enterprises : The Influence of Strategic Orientations and Management Values

Ecosystem degradation and social sustainability have become important issues in the corporate sphere during the last few decades. However, research discussing corporate social responsibility and related concepts has often focused on larger companies, sometimes neglecting the specifics of small and medium-sized enterprises (SMEs). The main purpose of this study is to examine the relationships betwe

Consumer eco-innovation adoption : Assessing attitudinal factors and perceived product characteristics

For business and environmental reasons, increased understanding of green consumer behavior is essential. This paper addresses consumer adoption and non-adoption of a high involvement eco-innovation (the alternative fuel vehicle, AFV). The purpose is to integrate two research streams to explore factors driving and hindering adoption. The factors are rooted in environmental psychology research and t

Language and meaning in a multilingual interdisciplinary teaching and learning context

The present study was undertaken in the frame of the research programme Language Use and Individual Learning at the Department of Education at Lund University, using the intentional-expressive dialogue format developed within this programme. The dialogue format was adjusted to study language use and understanding in a multilingual and interdisciplinary higher education context, by including questi

Direct monitoring of calcium-triggered phase transitions in cubosomes using small-angle X-ray scattering combined with microfluidics

This article introduces a simple microfluidic device that can be combined with synchrotron small-angle X-ray scattering (SAXS) for monitoring dynamic structural transitions. The microfluidic device is a thiol-ene-based system equipped with 125 μm-thick polystyrene windows, which are suitable for X-ray experiments. The device was prepared by soft lithography using elastomeric molds followed by a si

Inconsistent results in the analysis of ALK rearrangements in non-small cell lung cancer

Background: Identification of targetable EML4-ALK fusion proteins has revolutionized the treatment of a minor subgroup of non-small cell lung cancer (NSCLC) patients. Although fluorescence in situ hybridization (FISH) is regarded as the gold standard for detection of ALK rearrangements, ALK immunohistochemistry (IHC) is often used as screening tool in clinical practice. In order to unbiasedly anal

Acceptance, Attrition, and Outcome in an Outpatient Treatment Programme for Alcoholics : a Comparison Between a Randomized and a Non-Randomized Process-Outcome Study

Acceptance, attrition and outcome of the same outpatient treatment programme for alcoholics was studied first in a non-randomized and later in a randomized study. There was a lower (15%) rate of acceptance and a higher (19%) rate of attrition in the randomized study. Among treatment completers drinking outcome during the third year after commencement of treatment did not differ between the non-ran

Gaia Data Release 1 : Pre-processing and source list creation

Context. The first data release from the Gaia mission contains accurate positions and magnitudes for more than a billion sources, and proper motions and parallaxes for the majority of the 2.5 million Hipparcos and Tycho-2 stars. Aims. We describe three essential elements of the initial data treatment leading to this catalogue: the image analysis, the construction of a source list, and the near rea

Meniscus morphology : Does tear type matter? A narrative review with focus on relevance for osteoarthritis research

Objective: To give a narrative overview of meniscal tears with a radiologic emphasis on the morphologic type, technical considerations, and on the relevance of the type of meniscal tear in the context of osteoarthritis (OA) research. Design: Total 20 years of the PubMed database were searched for epidemiological, radiological, arthroscopic and biomechanical reports, and review articles focusing on
