This study assessed the ability of the tongue tip to accurately select intra-oral sensors embedded in a upper palatal interface of 19 able-bodied volunteers. Tongue selectivity performance measures were determined for three different tongue-computer interface layouts. Assessment of intra-oral target selection speed and accuracy revealed that performance was dependent on the location and distance b

The nuclear structure of neutron-rich N>126 nuclei has been investigated following their production via relativistic projectile fragmentation of a E/A=1 GeV U-238 beam. Metastable states in the N=128 isotones Hg-208 and Tl-209 have been identified. Delayed gamma-ray transitions are interpreted as arising from the decay of I-pi=(8(+)) and (17/2(+)) isomers, respectively. The data allow for the so f

Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation of the peripheral joints that eventually leads to cartilage destruction and bone erosion. The causes of RA remain largely unknown, but considerable evidence suggests a multifactorial aetiology involving both environmental and genetic factors. Large efforts have been directed towards the understanding of the mo

Popular Abstract in Swedish Leukemi är en cancersjukdom i blod och benmärg som karakteriseras av en störd blodbildning. Vid normal blodbildning delar sig ett begränsat antal omogna blodceller så kallade blod stamceller (eller hematopoietiska stamceller) och mognar till funktionella blodceller. Genom att dela sig utan att mogna har stamcellerna även potential till at förnya sig själva. När nya stamAcute myeloid leukemia (AML) is a malignant disorder of the blood system. Hematopoietic stem cells (HSCs) supply and maintain this system by differentiating via intermediates into lineage-restricted progenitors that strongly proliferate to keep up with the high turn-over of mature blood cells. In AML, the mechanisms controlling differentiation and proliferation of myeloid cells are disturbed leadi

When building shape models, it is first necessary to filter out the similarity transformations from the original configurations. This is normally done using Procrustes analysis, that is minimising the sum of squared distances between the corresponding landmarks under similarity transformations. In this article we propose to align shapes using the Minimum Description Length (MDL) criterion. Previou

Divergent-light halos are produced when light from nearby light sources is scattered by ice crystals in the atmosphere. We present a theory of divergent-light halos leading to an improved algorithm for the simulation of such halos. Contrary to the algorithm that we presented earlier for simulating such halos, the new algorithm includes a mathematically rigorous weighting of the events. The compute

This study investigates utilization of the Internet in the rehabilitation of people on long-term sick leave with chronic pain and/or burnout. Fifty-five people were randomly assigned to two groups: a treatment group (n = 27) that participated in a rehabilitation course over the Internet and a waiting list group (n = 28). The goals were to improve participants' health and increase quality of life,

Antibody-based microarray is a novel proteomic technology setting a new standard for molecular profiling of non-fractionated complex proteomes. The first generation of antibody microarrays has already demonstrated its potential for generating detailed protein expression profiles, or protein atlases, of human body fluids in health and disease, paving the way for new discoveries within the field of

Little has been reported on the association of derived body composition data and cardiovascular mortality. The authors defined body composition profiles based on one- and two-variable measures from dual-energy x-ray absorptiometry (DXA) total body scans. Scan results are labeled "apple" if Z score for percent of total fat in trunk is >0 and "pear" if Z score for height-corrected limb fat is > or =

Mental health problems among adolescents have become a major public health issue, and it is therefore important to increase knowledge on the contextual determinants of adolescent mental health. One such determinant is the socioeconomic structure of the neighbourhood. The present study has two central objectives, (i) to examine if neighbourhood socioeconomic deprivation is associated to individual

Popular Abstract in Swedish Målet avhandlingen har varit att undersöka möjligheten att bygga en kvantdator i kristaller dopade med joner av sällsynta jordartsmetaller. Det har visat sig att sådana joner har en väldigt lång livstid, vilket är en förutsättning för de typer av experiment som har utförts i den här avhandlingen. För att ytterliggare förhindra att de känsliga tillstånden i jonerna störsThis thesis describes a number of coherent processes, such as quantum information processing, superradiance and electromagnetically induced transparency, which have been experimentally implemented using rare-earth-ion-doped crystals. The rare-earths are a class of elements that have in common, an atomic structure that allows for very long lifetimes as well as coherence times, both on optical trans

Regime shifts in shallow lakes are typically characterized by submerged macrophyte (clear water regime) or phytoplankton (turbid regime) dominance. Climate warming is expected to affect water quality and facilitate turbidity in lakes, but we may also expect synergistic effects on organisms' interactions from climate and local specific dynamics in lakes. We here examined long-term changes in phytop

We have carried out a combined X-ray photoelectron spectroscopy (XPS), ultraviolet photoelectron spectroscopy(UPS), and scanning tunnelling microscopy (STM) study of the C-60-Si(1 1 1) interaction where the XPS/UPS spectrometer and STM are integrated on a single UHV system. This enables a direct comparison of the XPS/UPS spectra with the STM data and eliminates any uncertainty in C-60 coverage mea

Background: The evidence about nitrosamines and heme iron intake and cancer risk is limited, despite the biologic plausibility of the hypothesis that these factors might increase cancer risk. We investigated the association between dietary nitrosamines and heme iron and the risk of prostate cancer among participants of European Prospective Investigation into Cancer and Nutrition (EPIC). Methods: D

Nuclear Quadrupole Resonance (NQR) is a method of de- tection and unique characterization of compounds containing quadrupolar nuclei, commonly found in many forms of ex- plosives, narcotics, and medicines. Typically, multi-pulse sequences are used to acquire the NQR signal, allowing the resulting signal to be well modeled as a sum of exponentially damped sinusoidal echoes. In this paper, we improv
