Optimal geometry of lateral GaAs and Si/SiGe quantum dots for electrical control of spin qubits

We investigate the effects of the orientation of the magnetic field and the orientation of a quantum dot, with respect to crystallographic coordinates, on the quality of an electrically controlled qubit realized in a gated semiconductor quantum dot. We find that, due to the anisotropy of the spin-orbit interactions, by varying the two orientations it is possible to tune the qubit in the sense of o

Prices, debt and market structure in an agent-based model of the financial market

We develop an agent-based model in which heterogeneous and boundedly rational agents interact by trading a risky asset at an endogenously set price. Agents are endowed with balance sheets comprising the risky asset as well as cash on the asset side and equity capital as well as debt on the liabilities side. A number of findings emerge when simulating the model: we find that the empirically observa

Regio- and Stereoselective Alkylation of Pyridine-N-oxides : Synthesis of Substituted Piperidines and Pyridines

Regio- and stereoselective addition of alkyl Grignard reagents to pyridine-N-oxides gave C2-alkylated N-hydroxy-1,2,5,6-tetrahydropyridines and trans-2,3-disubstituted N-hydroxy-1,2,5,6-tetrahydropyridines in good to excellent yields. These intermediates were aromatized or alternatively reduced in one-pot methodologies for efficient syntheses of alkylpyridines or piperidines, respectively. These r

Effects of acute and chronic stress on telencephalic neurochemistry and gene expression in rainbow trout (Oncorhynchus mykiss)

By filtering relevant sensory inputs and initiating stress responses, the brain is an essential organ in stress coping and adaptation. However, exposure to chronic or repeated stress can lead to allostatic overload, where neuroendocrinal and behavioral reactions to stress become maladaptive. This work examines forebrain mechanisms involved in allostatic processes in teleost fishes. Plasma cortisol

COX7A2L/SCAFI and pre-complex III modify respiratory chain supercomplex formation in different mouse strains with a Bcs1l mutation

The COX7A2L (Supercomplex Assembly Factor I, SCAFI) protein has been proposed to be a mitochondrial supercomplex assembly factor required for respirasome (supercomplex containing complexes I, III, and IV) formation. In the C57BL/6 mouse strain a homozygous in-frame 6-base-pair deletion in the COX7a2l/SCAF1 gene resulting in unstable protein and suggesting loss of function was previously identified

Scrolling down the line : A few notes on using Instagram as point of access for graffiti research

This article discusses using social media, here Instagram, as a point of access in studies on subcultural graffiti, so as to provide an established arena for initiating contact with a variety of participants. Drawing from an ongoing ethnography of Swedish graffiti writers, the approach presented here works to mitigate the often so major hurdle within ethnographic work on subcultural groups: that o

On the diagnostic analysis of IEEE 1687 networks

The IEEE 1687 standard describes reconfigurable structures allowing to flexibly access the instruments existing within devices (e.g., to support test, diagnosis, calibration, etc.), by using configuration modules which act as controllable switches. The increasing adoption of this standard requires the availability of algorithms and tools to automate its usage. The resulting networks might be affec

Drosophila stardust is a partner of Crumbs in the control of epithelial cell polarity

The polarized architecture of epithelial cells depends on the highly stereotypic distribution of cellular junctions and other membrane-associated protein complexes. In epithelial cells of the Drosophila embryo, three distinct domains subdivide the lateral plasma membrane. The most apical one comprises the subapical complex (SAC). It is followed by the zonula adherens (ZA) and, further basally, by

Functional and evolutionary insights from the genomes of three parasitoid nasonia species

We report here genome sequences and comparative analyses of three closely related parasitoid wasps: Nasonia vitripennis, N. giraulti, and N. tongicomis. Parasitoids are important regulators of arthropod populations, including major agricultural pests and disease vectors, and Nasonia is an emerging genetic model, particularly for evolutionary and developmental genetics. Key findings include the ide

Cardiometabolic biomarkers are predictors of readmission and death in patients hospitalized for acute dyspnea

BACKGROUND: Acute dyspnea affects a large heterogeneous patient group with high mortality and readmission rates.PURPOSE: To investigate if cardiometabolic biomarkers and clinical characteristics predict readmission and death in patients hospitalized for acute dyspnea.METHODS: 65 dyspnea patients at a general internal medicine ward were followed for six months. The combined endpoint was readmission

Dissemination of research results from Lund University to industry and society

Sweden is top ranked as the third most innovative nation in the world according to Global Innovation Index 2015. The academic staff at Swedish universities has the right to their inventions (research-ownership of patent rights) as opposed to far more diffuse university-ownership. Since 1977 the Swedish Higher Education Act imposes Swedish universities a so-called Third task. In addition to educati

Portal Stability Controls Dynamics of DNA Ejection from Phage

Through a unique combination of time-resolved single-molecule (cryo-TEM) and bulk measurements (light scattering and small-angle X-ray scattering), we provide a detailed study of the dynamics of stochastic DNA ejection events from phage λ. We reveal that both binding with the specific phage receptor, LamB, and thermo-mechanical destabilization of the portal vertex on the capsid are required for in

A study of artificial eyes for the measurement of precision in eye-trackers

The precision of an eye-tracker is critical to the correct identification of eye movements and their properties. To measure a system’s precision, artificial eyes (AEs) are often used, to exclude eye movements influencing the measurements. A possible issue, however, is that it is virtually impossible to construct AEs with sufficient complexity to fully represent the human eye. To examine the conseq

Customer satisfaction with socially responsible investing initiatives : The influence of perceived financial and non-financial quality

During the last decade, socially responsible investment (SRI) initiatives have grown to become a mainstream financial service in many countries. However, to date, only a few studies focus on understanding the final investor of such initiatives. This article focuses on one particularly overlooked aspect of SRI behavior; that of customer post-purchase satisfaction. A theoretical model of satisfactio
