Introduction: Biomarkers for the prediction of cognitive decline in patients with amnestic mild cognitive impairment (MCI) and amnestic mild dementia are needed for both clinical practice and clinical trials. Methods: We evaluated the ability of tau-PET (positron emission tomography), cortical atrophy on magnetic resonance imaging (MRI), baseline cognition, apolipoprotein E gene (APOE) status, pla
Starch modified with octenyl succinic anhydride (OSA) is extensively used due to its emulsifying capacity. Modification with OSA renders the starch surface active but also anionic at intermediate pH. The amount of OSA that is grafted to the starch polymer backbone will influence the functionality. Likewise, it can be expected that the distribution of the substituents over the molar mass distributi
Extending the lifetime of products enables material resource savings and provides an effective resource efficiency strategy within a circular economy paradigm. Although consumer demand for longer lasting products that can be easily repaired has been on the rise, it is not certain that consumers are fully able to identify such products and willing to pay a premium for them. France introduced a mand
Not very long ago, the 3rd generation storage ring technology was judged as mature. Most of the 3rd generation storage rings used the Double-Bend Achromat (DBA) or Triple-Bend Achromat (TBA) concepts. It was however a well-known fact that increasing the number of magnet cells in the rings is a powerful way of decreasing the electron beam emittance and thus the source brilliance, but at the penalty
This paper presents preliminary results for a novel 128-antenna massive Multiple-Input, Multiple-Output (MIMO) testbed developed through Bristol Is Open in collaboration with National Instruments and Lund University. We believe that the results presented here validate the adoption of massive MIMO as a key enabling technology for 5G and pave the way for further pragmatic research by the massive MIM
The age of COVID-19 calls for a different approach toward global well-being and flourishing through the transcendence suffering as advocated by existential positive psychology. In the present study, we primarily explained what self-transcendence is and why it represents the most promising path for human beings to flourish through the transformation of suffering in a difficult and uncertain world.
All patients older than 65 years (184 men; mean age, 78+/-0.8 years/181 women; mean age, 82+/-0.6 years) seeking medical attention at the Lund University Hospital Emergency Clinic during a 2-year period who had an N-terminal prohormone brain natriuretic peptide (NT-proBNP) value >2000 pg/mL were followed up for survival. Mortality in the entire population was 21% after 3 months, 35% after 1 year,
This brief presents an efficient and configurable multiple-input–multiple-output (MIMO) signal detector design solution and its high-speed IC implementation. This detector can support 2 $times$ 2/3 $times$ 3/4 $times$ 4 MIMO and quadratic phase-shift keying/16-state quadratic amplitude modulation (QAM)/64-state QAM modulation configurations. The detection algorithm employs an early-pruned techniqu
Most text categorization methods use the vector space model in combination with a representation of documents based on bags of words. As its name indicates, bags of words ignore possible structures in the text and only take into account isolated, unrelated words. Although this limitation is widely acknowledged, most previous attempts to extend the bag-of-words model with more advanced approaches f
We report the development of a new database of technology services and products for analysis of biobank samples in biomedical research. BARCdb, the Biobanking Analysis Resource Catalogue (http://www.barcdb.org), is a freely available web resource, listing expertise and molecular resource capabilities of research centres and biotechnology companies. The database is designed for researchers who requ
Palaeomagnetic analysis of the Lakhna Dykes (Bastar Craton, India) yields a palaeopole at 36.6 degrees N, 132.8 degrees E, dp=12.4 degrees, dm=15.9 degrees, and the U-Pb zircon age obtained from one of the rhyolitic dykes is 1466.4 +/- 2.6 Ma (MSWD = 0.21, concordia age based on two analyses with identical Pb/U ages), similar to previously published U-Pb ages. Major and trace element analyses of t
This study (N = 102 women) evaluated the time course of posttraumatic stress symptomatology (PTSS) at different stages of nonmetastastic cancer diagnosis and treatment: during treatment, at the end of treatment, and at a 6-12 months follow-up. We also assessed the contribution of demographic, trait, and state predictors to PTSS, and coping processes as proximal mediators of the relation between Ty
Understanding spatial connections between breeding and wintering populations is critical for developing sound conservation plans in migratory animals. However, for long-distance migratory songbird species wintering in sub-Saharan Africa, many of which are in a state of population decline, information on migratory connectivity is especially lacking. We used mitochondrial DNA data from wintering pop
In this study, we examine the way access to welfare provision for migrants is articulated discursively among three right-of-center parties in Sweden. For this, we suggest two theoretical advances. First, deploying the concept of the right-wing continuum, we highlight the gradual and reciprocal alignment between mainstream right-of-center and radical-right populist parties. Second, by resorting to
Sodium-glucose transport protein 2 inhibitors (SGLT2i) slow the progression of renal dysfunction and improve the prognosis of patients with heart failure. Amyloidosis constitutes an important subgroup for which evidence is lacking. Amyloidotic fibrils originating from misfolded transthyretin and light chains are the causal agents in ATTR and AL amyloidosis. In these most frequent subtypes, cardiac
Previous research showed that living closer to bus stops could be a factor in promoting a healthy and active lifestyle. However, most of the studies relied on self-reported measures of distance, which might be affected by several confounders. In this study, self-reported distances among study participants were compared to actual ones, computed by the use of GIS (Geographic Information System) tech
This study investigates the suitability of heat conduction calorimeters for determining the specific heat capacity of solid and liquid substances. Accurate and precise measurements were obtained for various substances, including water, ethylene glycol, the ionic liquid [EMIM][TCM], and copper, with relative standard deviations averaging less than 1%. Measurements on [EMIM][DCA] indicated a systema
New particle formation via the ion-mediated sulfuric acid and ammonia molecular clustering mechanism remains the most widely observed and experimentally verified pathway. Recent laboratory and molecular level observations indicate iodine-driven nucleation as a potentially important source of new particles, especially in coastal areas. In this study, we assess the role of iodine species in particle
