Untreated celiac disease is traditionally believed to be associated with malabsorption and underweight. However, studies describing body mass index (BMI) in individuals at the time of diagnosis have shown contradictory results. We investigated the differences in weight, height, and BMI in 12- year-old children with screening-detected celiac disease compared to their healthy peers.
The reliability of the correlation dimension estimation in short hydrological time series is investigated using an inverse approach. According to this approach, first predictions are made using the phase-space reconstruction technique and the artificial neural networks. The correlation dimension is estimated next independently and is compared with the prediction results. A short hydrological serie
During vertebrate embryonic development, cellular senescence occurs at multiple locations. To date, it has been accepted that when there has been induction of senescence in an embryonic tissue, β-galactosidase activity is detectable at a pH as high as 6.0, and this has been extensively used as a marker of cellular senescence in vivo in both whole-mount and cryosections. Such senescence-associated
A compact, high-brightness and practically debris-free laser-plasma soft x-ray source for proximity x-ray lithography is described. The target of the source is small liquid fluorocarbon droplets injected into vacuum with a piezoelectrically vibrated nozzle. Emission from helium- and hydrogenlike fluorine in the 1.2-1.7 nm wavelength range was determined to similar to 2X10(12) photons/(sr-pulse). w
This thesis describes the initial development of a new high-brightness table-top soft X-ray source suitable for microscopy. The laser-plasma utilises liquid droplets as targets and the absolute line emission in the water window (A-=2.3-4.4 nm) is typically 1·1012 photons/(stedine·pulse). The narrow bandwidth radiation makes the source suitable for zone plate optics used in microscopy. Compared to
The power of attosecond pump-probe spectroscopy combined with advanced detection schemes, such as photoelectron/ion coincidence spectrometers and time-resolved photoelectron emission microscopy (PEEM), can be unleashed by properly accounting for the repetition rate of the source. In this work, we present a high-repetition rate (200 kHz) attosecond pulse source that opens up for exploring phenomena
Popular Abstract in Swedish Avhandlingen beskriver en ny typ av kompakt röntgenkälla baserad på ett laser-producerat plasma (LPP). I motsats till konventionella LPP används inte fasta material som strålmål för den fokuserade laserstrålen. I stället används mikroskopiska vätskedroppar eller vätskestrålar. Detta medför en mycket väsentlig minskning av det skräp (debris) som skickas ut från plasmat. A new high-brightness source for soft X-rays and EUV-radiation has been developed. This laser-plasma source utilizes a microscopic liquid droplet or jet as target. The result is a reduction of debris emission by several orders of magnitude compared to conventional laser plasmas. The minute amounts of residual ionic/atomic debris can be obstructed by filters or a localized gas shield. Target liquid

The global pandemic has initially negatively influenced the financial markets all over the world. As a consequence, the volatility in the stock markets increased and investors have experienced great monetary losses. In addition, the volatility spillover has increased between different markets and assets, which additionally amplifies the negative influence by the pandemic. This motivates the search
