1. Homogeneous Coordinates and Quotient Presentations for Toric Varieties

Author

A'Campo-Neuen, A., Hausen, J., and Schroeer, S.

Subjects
Mathematics - Algebraic Geometry, 14M25, 14C20, 14L30, 14L32
Abstract

Generalizing cones over projective toric varieties, we present arbitrary toric varieties as quotients of quasiaffine toric varieties. Such quotient presentations correspond to groups of Weil divisors generating the topology. Groups comprising Cartier divisors define free quotients, whereas $\QQ$-Cartier divisors define geometric quotients. Each quotient presentation yields homogeneous coordinates. Using homogeneous coordinates, we express quasicoherent sheaves in terms of multigraded modules and describe the set of morphisms into a toric variety., Comment: minor changes, to appear in Math.

2. On embeddings into toric prevarieties

Author

Hausen, J. and Schroeer, S.

Subjects
Mathematics - Algebraic Geometry, 14E25, 14M25
Abstract

What kind of schemes are embeddable into good toric prevarieties? To shed some light on this question, we construct proper normal surfaces that are embeddable into neither simplicial toric prevarieties nor toric prevarieties of affine intersection., Comment: 5 pages, minor changes, to appear in Proc.

Abstract

Little is known about the characteristics and treatments of patients with severe asthma across Europe, but both are likely to vary. This is the first study in the European Respiratory Society Severe Heterogeneous Asthma Research collaboration, Patient-centred (SHARP) Clinical Research Collaboration and it is designed to explore these variations. Therefore, we aimed to compare characteristics of patients in European severe asthma registries and treatments before starting biologicals.This was a cross-sectional retrospective analysis of aggregated data from 11 national severe asthma registries that joined SHARP with established patient databases.Analysis of data from 3236 patients showed many differences in characteristics and lifestyle factors. Current smokers ranged from 0% (Poland and Sweden) to 9.5% (Belgium), mean body mass index ranged from 26.2 (Italy) to 30.6 kg·m-2 (the UK) and the largest difference in mean pre-bronchodilator forced expiratory volume in 1 s % predicted was 20.9% (the Netherlands versus Hungary). Before starting biologicals patients were treated differently between countries: mean inhaled corticosteroid dose ranged from 700 to 1335 µg·day-1 between those from Slovenia versus Poland when starting anti-interleukin (IL)-5 antibody and from 772 to 1344 µg·day-1 in those starting anti-IgE (Slovenia versus Spain). Maintenance oral corticosteroid use ranged from 21.0% (Belgium) to 63.0% (Sweden) and from 9.1% (Denmark) to 56.1% (the UK) in patients starting anti-IL-5 and anti-IgE, respectively.The severe asthmatic population in Europe is heterogeneous and differs in both clinical characteristics and treatment, often appearing not to comply with the current European Respiratory Society/American Thoracic Society guidelines definition of severe asthma. Treatment regimens before starting biologicals were different from inclusion criteria in clinical trials and varied between countries.

5. Zeitgespraech - Ist der Fahrplan der Energiewende noch einzuhalten? - Mehr als eine kurzfristige Diskussion von Strompreisen und EEG-Umlage

Author

Gawel, E., Groth, M., Hansjuergens, B., Faulstich, M., Holm-Mueller, K., Kopp, O., Luhmann, H.-J., and Schroeer, S.

Abstract

Die Energiewende bedeutet eine Systemtransformation des gesamten Energiebereichs hin zu erneuerbaren Energien. Der Transformationsprozess ist dabei einerseits von hohen technologischen Herausforderungen begleitet. Andererseits zeigen sich aber auch zunehmend Akzeptanzprobleme in der Bevölkerung, wenn etwa die Strompreise als zu hoch empfunden werden und dies ausschließlich der Förderung der Erneuerbaren zugeschrieben wird. Die Autoren zeigen die vielen Hindernisse auf, die den Fahrplan der Energiewende ins Wanken bringen können.

Abstract

Background: Research on intermittent fasting has shown that it can improve a variety of health outcomes, including blood sugar control, blood lipid levels and blood pressure. Only few studies document longer periods of fasting, especially in rehabilitation participants. Cardiac inpatient rehabilitation follows a multidisciplinary approach including change of health behaviour to reduce patients' risk of future cardiovascular events. To date, evidence suggests that intermittent fasting can be an effective way to improve health and well-being, but more research is needed to fully understand its long-term effects and factors that promote the implementation. Therefore, the aim of the ongoing InterVFast trial is to investigate the effectiveness of intermittent fasting amongst cardiac rehabilitation patients after 4-week inpatient rehabilitation as well as 3 and 12 months subsequently including patients' perspective., Methods: This single-centre randomized controlled trial evaluates the effectiveness of the InterVFast intervention in weight loss (primary outcome). We also examine patients' acceptance and the effect on relevant outcomes as blood glucose and triglyceride levels, cholesterol and high-sensitivity C-reactive protein. Weight, blood samples and clinical data are collected as part of the initial and final examination during inpatient rehabilitation. During inpatient rehabilitation, participants daily note fasting intervals and meals eaten as well as practicability in a fasting diary. In addition, interviews about perceived advantages and disadvantages and acceptance are carried out with the participants in the IG. A standardized follow-up examination (weight, blood samples) will be carried out by the family doctor after 3 and 12 months (t2 and t3)., Discussion: Compared to other weight-loss intervention studies, our study addresses patients with coronary heart disease and includes patients' acceptance as well as long-term maintenance. It is hypothesized that participation in the InterVfast intervention will improve relevant health outcomes in a sample of cardiac rehabilitation patients and thus constitute a behavioural prevention strategy to reduce the risk of future cardiac events and improve overall health and quality of life., Trial Registration: ClinicalTrials.gov DRKS00023983.

Abstract

Background: Promoting health-enhancing physical activity following rehabilitation is a well-known challenge. This study analysed the barriers to leisure time activity among low back pain patients., Methods: A subset of 192 low back pain patients who participated in a randomized controlled trial promoting physical activity was analysed. Physical activity, barriers, and sociodemographic and indication-related variables were assessed by a questionnaire. Differences in barriers between active and inactive participants were tested by Pearson's chi squared test. A logistic regression model was fitted to identify influencing factors on physical activity at six months following rehabilitation., Results: Inactive and active participants differed significantly in nine of the 19 barriers assessed. The adjusted regression model showed associations of level of education (OR = 5.366 [1.563; 18.425]; p value = 0.008) and fear of pain (OR = 0.612 [0.421; 0.889]; p value = 0.010) with physical activity. The barriers included in the model failed to show any statistically significant association after adjustment for sociodemographic factors., Conclusions: Low back pain patients especially with a low level of education and fear of pain seem to need tailored support in overcoming barriers to physical activity. This study is registered at German Clinical Trials Register (DRKS00004878).

11. Next-Generation Sequencing Library Preparation from FFPE Tissue Samples.

Author

Wolf K, O'Neil D, Schroeer S, and Fang N

Abstract

Formalin-fixed, paraffin-embedded (FFPE) tissue samples represent an invaluable biobank for retrospective cancer research with molecular methods such as real-time PCR and next-generation sequencing (NGS). However, the usage of FFPE material in NGS approaches involves several challenges associated with the limited quantity and quality of DNA. This protocol describes how to purify DNA from FFPE material and how to prepare it for downstream NGS workflows including fragmentation, size selection, and library preparation for Illumina MiSeq/HiSeq sequencing. © 2016 by John Wiley & Sons, Inc., (Copyright © 2016 John Wiley & Sons, Inc.)
