Summary: Overweight and obesity constitute a major and increasing health and welfare problem throughout the world. Assessing the multifaceted mechanisms – biological, environmental and behavioural – behind this development is a crucial task in medical, social and economic sciences. We are, therefore, grateful to have been given the opportunity to, once again, discuss whether the risk of divorce ma
It is still unclear whether carbohydrate consumption is associated with cardiovascular disease (CVD) risk. Genetic susceptibility might modify the associations between dietary intakes and disease risk.
Correct operation of real-time systems (RTS) is defined as producing correct results within given time constraints (deadlines). As RTS are becoming more susceptible to soft errors, employing fault-tolerant techniques is crucial. Rollback Recovery with Checkpointing (RRC) is an efficient fault-tolerant technique. However, RRC introduces a time overhead which depends on the number of checkpoints. Th
The complexity status of the minimum r-star cover problem for orthogonal polygons had been open for many years, until 2004 when Ch. Worman and J. M. Keil proved it to be polynomially tractable (Polygon decomposition and the orthogonal art gallery problem, IJCGA 17(2) (2007), 105-138). However, since their algorithm has (O) over tilde (n(17))-time complexity, where (O) over tilde (.) hides a polylo
In the search for the fully aligned 27(-) state in Nd-140 predicted by cranked Nilsson-Strutinsky calculations, new close-to-spherical high-spin states have been discovered. Both the close-to-spherical and the triaxial calculated states are in good agreement with the experimental results, supporting the existence of shape coexistence up to very high spins. Shell-model calculations using a newly de
The BCJR algorithm is an important channel decoding method. We extend it to trellis rate-distortion data compression. Beginning from source coding principles, the derivation of the algorithm avoids channel coding or soft output ideas. The encoder does not use entropy coding; equiprobable reproducer letters are emphasized since these maximize entropy. The BCJR method is demonstrated by tests of a
VIX, published by the Chicago Board Options Exchange, is a well known implied volatility estimator. In this paper we assess its capability to be used as a sentiment indicator, and to give signals for a short term investment strategy. It will be proved and discussed how VIX-based strategies – also known as “Contrarian” strategies – can be effective as they lead to higher returns than the market. We
In 1996, Robert A. Haugen and Nardin L. Baker published a study where they had made a multi-factor model based on micro-variables on the American stock market between 1979 and 1993. In testing the model on the examined period they made an average annual return of 30,9 percent. They also tested the model on several other markets around the world with similar results. This study is a somewhat simple
This study explains why Sexual and Reproductive Health (SRH) among youths continuously pose challenges in the Lusaka area of Zambia, despite multiple Non-Governmental Organizations (NGOs) targeting this. An embedded case study design was applied and staff and youths engaged in NGOs working with youths’ SRH were main informants. The Social Ecological Theory was applied to widen the approach of prev
The precise valuation and correct assessment of the value of imported goods should be preceded by determining the value of imported goods for Customs purposes. The provisions regulating the Customs valuation are overlapped and complicated; the reason which prompted the Author, through this paper, to eliminate this overlaps and simplify the complexity, using a new approach represented by reclassify
Many common neurological disorders, such as Parkinson's disease, stroke and multiple sclerosis, are caused by a loss of neurons and glial cells. In recent years, neurons and glia have been generated successfully from stem cells in culture, fuelling efforts to develop stem-cell-based transplantation therapies for human patients. More recently, efforts have been extended to stimulating the formation
Many countries in Europe have experienced growing migration since World War II. It is estimated that more than one in five Swedes living today has roots in other countries and cultures. Segregation in terms of ethnic origin in housing areas makes it easier to maintain the language and cultural traditions of the home country when it comes to cooking and eating. In extremely segregated housing areas
The conflict between Armenia and Azerbaijan over Nagorno-Karabakh has put the Islamic regime of Iran in a difficult position. While the government is trying to be neutral, other regime elements have openly taken sides in the conflict.
Experimental studies suggest that hepatocyte growth factor (HGF) and its transmembrane tyrosine kinase receptor, Met, in part also relying on Akt kinase activity, mediate radioresistance. We investigated the importance of these biomarkers for the risk of ipsilateral breast tumour recurrence (IBTR) after adjuvant radiotherapy (RT) in primary breast cancer. HGF, phosphorylated Met (pMet) and phospho
A flat plate and a tubular packed-bed photobioreactor with an algal-bacterial biofilm attached onto Poraver((R)) beads carriers, a flat plate and a tubular photobioreactor with the biofilm attached onto the reactor walls, and an algal-turf reactor were compared in terms of BOD removal efficiencies, elimination capacities, and stability. A control column photobioreactor with suspended algal-bacteri
The detection of spectral line profile variability for stars of the HgMnclass of chemical peculiarity has been poorly documented in theliterature yet holds a special significance for understandingrelationships between observed spectral anomalies, stellar surfacestructure, and magnetic fields. The HgMn stars have until now not beenconfirmed to vary in their light or spectral characteristics in ways
Previous studies have shown that serotonin neurons play an important role in the induction and maintenance of l-DOPA-induced dyskinesia in animals with lesion of the nigrostriatal dopamine system. Patients with Parkinson's disease that receive transplants of foetal ventral mesencephalic tissue, the graft cell preparation is likely to contain, in addition to dopamine neurons, serotonin neurons that
