Simultaneous compression, characterization and phase stabilization of GW-level 1.4 cycle VIS-NIR femtosecond pulses using a single dispersion-scan setup

We have temporally characterized, dispersion compensated and carrier-envelope phase stabilized 1.4-cycle pulses (3.2 fs) with 160 mu J of energy at 722 nm using a minimal and convenient dispersion-scan setup. The setup is all inline, does not require interferometric beamsplitting, and uses components available in most laser laboratories. Broadband minimization of third-order dispersion using propa

Supplemental instruction for improving first year results in engineering studies

Many studies have been made on the impact of supplemental instruction in supported courses, most show significantly better examination results for students attending supplemental instruction in comparison to those who do not. However, remarkably little attention has been devoted to following up whether the benefits of supplemental instruction reach beyond the course it supports. The present study

Diagnosing and Mapping Pulmonary Emphysema on X-Ray Projection Images: Incremental Value of Grating-Based X-Ray Dark-Field Imaging

Purpose: To assess whether grating-based X-ray dark-field imaging can increase the sensitivity of X-ray projection images in the diagnosis of pulmonary emphysema and allow for a more accurate assessment of emphysema distribution. Materials and Methods: Lungs from three mice with pulmonary emphysema and three healthy mice were imaged ex vivo using a laser-driven compact synchrotron X-ray source. Me

Comparison between remote sensing and a dynamic vegetation model for estimating terrestrial primary production of Africa

Africa is an important part of the global carbon cycle. It is also a continent facing potential problems due to increasing resource demand in combination with climate change-induced changes in resource supply. Quantifying the pools and fluxes constituting the terrestrial African carbon cycle is a challenge, because of uncertainties in meteorological driver data, lack of validation data, and potent

Increased risk of end-stage renal disease in individuals with coeliac disease

Objective The prevalence of end-stage renal disease (ESRD) is increasing worldwide. Although increased levels of coeliac disease (CD) autoantibodies are often seen in renal disease, the importance of biopsy-verified CD for the risk of future ESRD is unclear. The aim of this study was therefore to investigate the risk of future ESRD in individuals with CD. Methods This was a population-based prospe

Increased availability of NADH in metabolically engineered baker's yeast improves transaminase-oxidoreductase coupled asymmetric whole-cell bioconversion.

Saccharomyces cerevisiae can be engineered to perform a multitude of different chemical reactions that are not programmed in its original genetic code. It has a large potential to function as whole-cell biocatalyst for one-pot multistep synthesis of various organic molecules, and it may thus serve as a powerful alternative or complement to traditional organic synthetic routes for new chemical enti

Sparse Localization of Harmonic Audio Sources

In this paper, we propose a novel method for estimating the locations of near- and/or far-field harmonic audio sources impinging on an arbitrary, but calibrated, sensor array. Using a joint pitch and location estimation formed in two steps, we first estimate the fundamental frequencies and complex amplitudes under a sinusoidal model assumption, whereafter the location of each source is found by ut

Using Supplemental Instruction to Bridge the Transition from Secondary to Tertiary Education

Supplemental Instruction (SI) is today a well known academic assistance program, providing help for students in “difficult” courses at colleges and universities. Little attention has been paid however to the possibility of also implementing the SI program in upper secondary school. In this study we present qualitative results from such an SI program in a Swedish setting. Here, students from the fa

Radio-Frequency Characterization of Selectively Regrown InGaAs Lateral Nanowire MOSFETs

We demonstrate InGaAs multigate MOSFETs, so-called FinFETs. The lateral nanowires constituting the channel in these devices have been formed using selective area regrowth, where the surfaces of the nanowires are crystallographic planes. L-g = 32 nm devices exhibit peak transconductance of 1.8 mS/mu m at V-ds = 0.5 V. We also report on RF characterization of these devices. A small-signal hybrid-p m

Evaluation of the Mechanistic-Empirical Pavement Design Guide model for permanent deformations in asphalt concrete

The model for permanent deformation in asphalt concrete (AC) layers used in the Mechanistic-Empirical Pavement Design Guide (MEPDG) was evaluated. Two instrumented flexible pavements were subjected to heavy vehicle simulator testing at three constant temperatures. Permanent deformation modelling was carried out using the MEPDG software v1.003 at the highest accuracy level. The nationally calibrate

Liposuction Normalizes - in Contrast to Other Therapies - Lymphedema-Induced Adipose Tissue Hypertrophy

The various types of treatment of lymphedema are under discussion and there has been some controversy regarding liposuction for lymphedema. Although it is clear that conservative therapies such as complex decongestive therapy (CDT) and controlled compression therapy (CCT) should be tried in the first instance, options for the treatment of late-stage lymphedema that is not responding to such treatm

Selective interlayer ferromagnetic coupling between the Cu spins in YBa2Cu3O7-x grown on top of La0.7Ca0.3MnO3.

Studies to date on ferromagnet/d-wave superconductor heterostructures focus mainly on the effects at or near the interfaces while the response of bulk properties to heterostructuring is overlooked. Here we use resonant soft x-ray scattering spectroscopy to reveal a novel c-axis ferromagnetic coupling between the in-plane Cu spins in YBa2Cu3O7-x (YBCO) superconductor when it is grown on top of ferr

Multibeam fluorescence diffuse optical tomography using upconverting nanoparticles.

Fluorescence diffuse optical tomography (FDOT) is a biomedical imaging modality that can be used for localization and quantification of fluorescent molecules inside turbid media. In this ill-posed problem, the reconstruction quality is directly determined by the amount and quality of the information obtained from the boundary measurements. Regularly, more information can be obtained by increasing

Marginal and Virtual Water for Sustainable Water Resources Management in Syria

Arid and semiarid Middle Eastern countries generally, and Syria in particular, face serious water shortage problems and challenges with water sustainability. Climate change, population growth, and economic development play a major role in decreasing available water resources per capita. This, in turn, has great impact on domestic, agricultural, and industrial water use. In this study, marginal and

Catholic Mission and Conversion in Scandinavia: Some Reflections on Religion, Modernization, and Identity Construction

The relation between mission, religious conversion and identity construction is the subject of my paper. On a concrete level, I discuss the Catholic mission and conversions in Scandinavia from the middle of nineteenth century to the present time. Up to the Second Vatican Council (1962-65), the Catholic Church strongly emphasised its claim to be the only true Church, and as a consequence, all non-C

Intakes of omega-3 polyunsaturated fatty acids and blood pressure change over time: Possible interaction with genes involved in 20-HETE and EETs metabolism.

A high intake of omega-3 polyunsaturated fatty acids (ω-3 PUFAs), has been associated with reduced levels of blood pressure (BP). Their antihypertensive action may be due to the reduction of the ω-6/ω-3 ratio and the resulting competitive effect of ω-3 as compared to arachidonic acid (an ω-6 PUFA) as a substrate of cytochrome P450 (CYP450) enzymes involved in the production of vasoactive mediators

The Changing Face of Arctic Snow Cover: A Synthesis of Observed and Projected Changes

Analysis of in situ and satellite data shows evidence of different regional snow cover responses to the widespread warming and increasing winter precipitation that has characterized the Arctic climate for the past 40-50 years. The largest and most rapid decreases in snow water equivalent (SWE) and snow cover duration (SCD) are observed over maritime regions of the Arctic with the highest precipita
