Emerging theoretical concepts for quantum technologies have driven a continuous search for structures where a quantum state, such as spin, can be manipulated efficiently. Central to many concepts is the ability to control a system by electric and magnetic fields, relying on strong spin-orbit interaction and a large g-factor. Here, we present a mechanism for spin and orbital manipulation using smal

The procedure of aligning a positron emission tomography (PET) image with a common coordinate system, spatial normalization, typically demands a corresponding structural magnetic resonance (MR) image. However, MR imaging is not always available or feasible for the subject, which calls for enabling spatial normalization without MR, MR-less spatial normalization. In this work, we propose a template-

Isosorbide-5-methacrylate was obtained by enzymatic catalysis with Lipozyme RM IM in a highly regioselective manner in up to 87% yield. The process uses readily available acyl donors (methacrylic anydride or vinyl methacrylate), is easily scalable and chromatography free. Simple extractive workup followed by decoloration and filtration affords the monomer with up to > 99% purity. In addition, the

BACKGROUND: Mental health problems are the main cause of sick leave in today's working age population. Employers are responsible for their employees' work environment and preventing work-related illnesses, but their knowledge regarding mental health problems is lacking. Employer beliefs and support strategies need further exploration. OBJECTIVE: To explore employers' beliefs, knowledge and strateg

In recent years, Sweden has tightened its legislation in a number of areas which provides the society good opportunities for combating street violence, writes Criminologist Ardavan Khoshnood.

This chapter analyses the European Union’s efforts to counteract the erosion of member states’ corporate tax bases. The author first describes how multinational enterprises, like Apple, have been able to exploit differences between the tax systems in order to pay less taxes. The author then presents the hypothesis that EU member states have managed to defend their interests in protecting their own

The Shortest Vector Problem (SVP) is one of the mathematical foundations of lattice based cryptography. Lattice sieve algorithms are amongst the foremost methods of solving SVP. The asymptotically fastest known classical and quantum sieves solve SVP in a $d$-dimensional lattice in $2^{\const d + \smallo(d)}$ time steps with $2^{\const' d + \smallo(d)}$ memory for constants $c, c'$. In this work, w

In this article, we aim to contribute to the literature on social identification among migrants and minorities by offering a theoretical framework that accounts for the interplay of socio-psychological factors, local and transnational group dynamics, and the socio-political environment in which migrants live. This approach enables us to analyse not only the political significance of identity, but

In this study, we have investigated the possibility of membrane filtration as a means for obtaining a fraction containing mainly low-molecular-weight (LMW) compounds from depolymerised lignin (DL) for subsequent microbial conversion. A DL stream from continuous-mode alkali depolymerisation of a softwood kraft lignin produced at a temperature of 220 °C and a residence time of 2 min, using a NaOH/li

Den svenska kommunala arbetsmarknadspolitiken har expanderat sedan 1990-talet. Kommunala arbetsmarknadsåtgärder kostar 5 miljarder, involverar 5 300 årsarbetare och 110 000 deltagare årligen. Enligt den senaste kunskapssammanställningen publicerad 2012 är kunskapen om vad somgörs och uppnås begränsad. I artikeln sammanfattas kunskapsläget mellan 2012-17. Vi genomför en systematisk forskningsöversi

Psychological models of pediatric obsessive-compulsive disorder (OCD) place a heavy emphasis on harm avoidance as a maintaining factor and target for treatment. Incompleteness and disgust may also play a role in pediatric OCD but remain under studied. Youth with OCD (n=100), anxiety disorders (n=96), and no psychiatric disorder (n=25) completed self-report measures of trait-level incompleteness, h

The T cell receptor (TCR) initiates the elimination of pathogens and tumors by T cells. To avoid damage to the host, the receptor must be capable of discriminating between wild-type and mutated self and nonself peptide ligands presented by host cells. Exactly how the TCR does this is unknown. In resting T cells, the TCR is largely unphosphorylated due to the dominance of phosphatases over the kina

In patients admitted alive to hospital after cardiac arrest the most common mode of death is withdrawal of life sustaining therapy due to brain injury. This decicion is preceeed by multimodal neuroprognostication, which includes clinical examination, neurophysiological tests, imagning and serum markers of braininjury.

Lake ice is a robust indicator of climate change. The availability of information contained in Moderate Resolution Imaging Spectroradiometer daily snow products from 2000 to 2017 could be greatly improved after cloud removal by gap filling. Thresholds based on open water pixel numbers are used to extract the freezeup start and breakup end dates for 58 lakes on the Tibetan Plateau (TP); 18 lakes ar

Precipitation and air temperature are key drivers of watershed models. Currently there are many open-access gridded precipitation and air temperature datasets at different spatial and temporal resolutions over global or quasi-global scale. Motivated by the scarcity and substantial temporal and spatial gaps in ground measurements in Africa, this study evaluated the performance of three open-access

Spatial and temporal patterns of trends in annual and seasonal precipitation over Germany during 1951–2013 were analysed using the ensemble empirical mode decomposition (EEMD) method. Three widely used and recognized high-resolution observation-based gridded precipitation products, the Climatic Research Unit (CRU) time-series data, Global Precipitation Climatology Centre (GPCC) Full Data Reanalysi

This study conducted the global sensitivity analysis of the APSIM-Oryza rice growth model under eight climate conditions and two CO2 levels using the extended Fourier Amplitude Sensitivity Test method. Two output variables (i.e. total aboveground dry matter WAGT and dry weight of storage organs WSO) and twenty parameters were analyzed. The ±30% and ±50% perturbations of base values were used as th

Surface water is vital resources for terrestrial life, while the rapid development of urbanization results in diverse changes in sizes, amounts, and quality of surface water. To accurately extract surface water from remote sensing imagery is very important for water environment conservations and water resource management. In this study, a new Multi-Band Water Index (MBWI) for Landsat 8 Operational

Understanding responses by changes in land use and land cover (LULC) and climate over the past decades on streamflow in the upper Blue Nile River basin is important for water management and water resource planning in the Nile basin at large. This study assesses the long-term trends of rainfall and streamflow and analyses the responses of steamflow to changes in LULC and climate in the upper Blue N
