Several organizations have developed prediction models for molecular breeding values (MBV) for quantitative growth and carcass traits in beef cattle using Bovine SNP50 genotypes and phenotypic or EBV data. Molecular breeding values for Angus cattle have been developed by IGENITY, Pfizer Animal Genetics, and a collaboration between researchers from Iowa State University and the University of Missouri-Columbia (ISU/UMC). The U.S. Meat Animal Research Center (USMARC; Clay Center, NE) has also developed MBV for 16 cattle breeds using 2 multibreed populations, the Germplasm Evaluation (GPE) Program and the 2,000 Bull Project (2K(ALL)), and 2 single breed subpopulations of the 2,000 Bull Project, Angus (2K(AN)) and Hereford (2K(HH)). In this study, these MBV were assessed relative to commercial ranch EBV estimated from the progeny phenotypes of Angus bulls naturally mated in multisire breeding pastures to commercial cows: 121 for USMARC MBV, 99 for ISU/UMC MBV, and 29 for IGENITY and Pfizer MBV (selected based on number of progeny carcass records). Five traits were analyzed: weaning weight (WW), HCW, marbling score (MS), rib-eye muscle area (RE), and, for IGENITY and Pfizer only, feedlot ADG. The average accuracies of MBV across traits were 0.38 ± 0.05 for IGENITY, 0.61 ± 0.12 for Pfizer, 0.46 ± 0.12 for ISU/UMC, 0.16 ± 0.04 for GPE, 0.26 ± 0.05 for 2K(ALL), 0.24 ± 0.04 for 2K(AN), and 0.02 ± 0.12 for 2K(HH). Angus-based MBV (IGENITY, Pfizer, ISU/UMC, and 2K(AN)) explained larger proportions of genetic variance in this population than GPE, 2K(ALL), or 2K(HH) MBV for the same traits. In this data set, IGENITY, Pfizer, and ISU/UMC MBV were predictive of realized performance of progeny, and incorporation of that information into national genetic evaluations would be expected to improve EPD accuracy, particularly for young animals.

This article describes the DataBox project which offers a perspective of a new health data management solution in Germany. DataBox was initially conceptualized as a repository of individual lung cancer patient data (structured and unstructured). The patient is the owner of the data and is able to share his or her data with different stakeholders. Data is transferred, displayed, and stored online, but not archived. In the long run, the project aims at replacing the conventional method of paper- and storage-device-based handling of data for all patients in Germany, leading to better organization and availability of data which reduces duplicate diagnostic procedures, treatment errors, and enables the training as well as usage of artificial intelligence algorithms on large datasets. ©Titus Josef Brinker, Stefanie Rudolph, Daniela Richter, Christof von Kalle.

The costs and benefits of a cigarette ban.

PubMed

Doucet, Mathieu

2017-06-01

The death toll from tobacco is staggering: it might contribute to one billion premature deaths over the course of the 21st century. In 'The case for banning cigarettes', Kalle Grill and Kristin Voigt argue that the well-being and equality benefits of a complete ban on cigarettes more than justify the restrictions on autonomy that such a ban would impose. Their argument depends on two crucial simplifications: an assumption that the ban would be effective and the restriction of the analysis to a comparison with the status quo, rather than a broader range of policy options. I argue that despite the authors' claims, these two simplifications make it impossible for their argument to 'bring into focus the fundamental normative issues' surrounding a possible cigarette ban, since they dramatically overstate the benefits and obscure the most significant costs of such a ban.

1992-12-02

Restructuring of Europe's petrochemical industry has taken a further step with the announcement that Hoechst (Frankfurt) and Wacker Chemie (Munich) are planning a joint venture in polyvinyl chloride (PVC). The venture would include production, R D, sales and marketing, plus both companies' PVC recycling activities. However, their vinyl chloride monomer (VCM) plants, and Hoechst's Kalle PVC film business, have been left out. Erich Schnitzler, head of Hoechst's PVC business unit, does not anticipate problems with the European Community's competition directorate. We are both among the middle-sized European PVC producers, and together we would have a 9%-10% market share. Our jointmore » venture would not limit competition. Both partners are hoping for approval from Brussels in first-quarter 1993. Hoechst has 255,000 m.t./year of PVC capacity at Gendorfand Knapsack, while Wacker has 365,000 m.t./year at Burghausen and Cologne. All the units, except Wacker's Cologne plant, are back integrated to VCM. The joint venture would buy VCM from the two parent companies and on the merchant market.« less

Observable patterns of cultural variation are consistently intertwined with demic movements, cultural diffusion, and adaptation to different ecological contexts [Cavalli-Sforza and Feldman (1981) Cultural Transmission and Evolution: A Quantitative Approach; Boyd and Richerson (1985) Culture and the Evolutionary Process]. The quantitative study of gene–culture coevolution has focused in particular on the mechanisms responsible for change in frequency and attributes of cultural traits, the spread of cultural information through demic and cultural diffusion, and detecting relationships between genetic and cultural lineages. Here, we make use of worldwide whole-genome sequences [Pagani et al. (2016) Nature 538:238–242] to assess the impact of processes involving population movement and replacement on cultural diversity, focusing on the variability observed in folktale traditions (n = 596) [Uther (2004) The Types of International Folktales: A Classification and Bibliography. Based on the System of Antti Aarne and Stith Thompson] in Eurasia. We find that a model of cultural diffusion predicted by isolation-by-distance alone is not sufficient to explain the observed patterns, especially at small spatial scales (up to ∼4,000 km). We also provide an empirical approach to infer presence and impact of ethnolinguistic barriers preventing the unbiased transmission of both genetic and cultural information. After correcting for the effect of ethnolinguistic boundaries, we show that, of the alternative models that we propose, the one entailing cultural diffusion biased by linguistic differences is the most plausible. Additionally, we identify 15 tales that are more likely to be predominantly transmitted through population movement and replacement and locate putative focal areas for a set of tales that are spread worldwide.

2017-02-15

Liquid chromatography is frequently used as a means to reduce the complexity of peptide-mixtures in shotgun proteomics. For such systems, the time when a peptide is released from a chromatography column and registered in the mass spectrometer is referred to as the peptide's retention time . Using heuristics or machine learning techniques, previous studies have demonstrated that it is possible to predict the retention time of a peptide from its amino acid sequence. In this paper, we are applying Gaussian Process Regression to the feature representation of a previously described predictor E lude . Using this framework, we demonstrate that it is possible to estimate the uncertainty of the prediction made by the model. Here we show how this uncertainty relates to the actual error of the prediction. In our experiments, we observe a strong correlation between the estimated uncertainty provided by Gaussian Process Regression and the actual prediction error. This relation provides us with new means for assessment of the predictions. We demonstrate how a subset of the peptides can be selected with lower prediction error compared to the whole set. We also demonstrate how such predicted standard deviations can be used for designing adaptive windowing strategies. lukas.kall@scilifelab.se.

Chemistry of the Marlboro Clay in Virginia and Implications for the Paleocene-Eocene Thermal Maximum

The Paleocene-Eocene Thermal Maximum (PETM) was a global hyperthermal ( 5ºC warming) event marked by a rapid carbon isotope excursion (CIE) of >1‰ in the marine carbonate record (e.g. Zeebe et al. Nature Geoscience 2009). Possible explanations for the CIE include intrusion of a sill complex into organic carbonate (Aarnes et al. J. Geol. Soc. 2015), dissolution of methane hydrates (Thomas et al. Geology 2002), and a comet impact event (Schaller et al. Science 2016). Here we present new data across the PETM from the VirginiaDEQ-USGS Surprise Hill (SH) core, Northumberland Co., VA. We analyzed the Marlboro Clay, a thick, kaolinite-rich clay unit that marks the initiation of the PETM in the mid-Atlantic Coastal Plain of North America, as well as units above and below it. Bulk sediment records a δ13C excursion of approximately -5‰ across the CIE, while benthic foraminifera (Cibicidoides spp.) record a synchronous excursion of approximately -4.5‰. These results are consistent with other records from the New Jersey Coastal Plain (Makarova et al. Paleoceanography 2017). The excursion coincides with an increase in magnetic susceptibility, a decrease in bulk CaCO3 content, and an 2.5‰ decrease of δ18O in both the bulk sediment and benthic foraminifera of the SH core. Pb isotope analyses of the <63 μm fraction sediments indicate a unique provenance make-up for the Marlboro Clay. The results of the study thus indicate that PETM Marlboro Clay was not generated simply by intensified weathering of the same source area as the underlying Aquia Formation and overlying Nanjemoy Formation. Any hypothesis that aims to explain the mechanism that triggered the PETM must also account for the observed distinct provenance make-up of the Marlboro Clay.

Melatonin is normally consumed to regulate the body's biological cycle. However it also has therapeutic properties, such as anti-tumor, anti-aging and protects the immune system. There are some reports on the presence of melatonin in edible kernels such as walnuts, but the extraction of melatonin from pistachio kernels is reported here for the first time. For this, the methanolic extract of pistachio kernels was exposed to gas chromatography/mass spectrometry analysis which confirmed the presence of melatonin. A fluorescence-based method was applied for the determination of melatonin in different extracts. When excited at λ=275 nm, the fluorescence emission intensity of melatonin was measured at λ=366 nm. Ultrasound-assisted solid-liquid extraction was used for the extraction of melatonin from pistachio kernels prior to fluorimetric determination. To achieve the highest extraction recovery, the main parameters affecting the extraction efficiency such as extracting solvent type and volume, temperature, sonication time and pH were evaluated. Under the optimized conditions, a linear dependence of fluorescence intensity on melatonin concentration was observed in the range of 0.0040-0.160 μg mL(-1), with a detection limit of 0.0036 μg mL(-1). This method was applied successfully for measuring and comparing the melatonin content in the kernels of four different varieties of Pistacia including Ahmad Aghaei, Akbari, Kalle Qouchi and Fandoghi. In addition, the results obtained were compared with those obtained using GC/MS. A good agreement was observed indicating the reliability of the proposed method. Copyright © 2014 Elsevier B.V.

Early-onset prostate cancer (EO-PCA) represents the earliest clinical manifestation of prostate cancer. To compare the genomic alteration landscapes of EO-PCA with "classical" (elderly-onset) PCA, we performed deep sequencing-based genomics analyses in 11 tumors diagnosed at young age, and pursued comparative assessments with seven elderly-onset PCA genomes. Remarkable age-related differences in structural rearrangement (SR) formation became evident, suggesting distinct disease pathomechanisms. Whereas EO-PCAs harbored a prevalence of balanced SRs, with a specific abundance of androgen-regulated ETS gene fusions including TMPRSS2:ERG, elderly-onset PCAs displayed primarily non-androgen-associated SRs. Data from a validation cohort of>10,000 patients showed age-dependent androgen receptor levels and a prevalence of SRs affecting androgen-regulated genes, further substantiating the activity of a characteristic "androgen-type" pathomechanism in EO-PCA.

BACKGROUND Functional hypothalamic amenorrhea is a reversible form of gonadotropin-releasing hormone (GnRH) deficiency commonly triggered by stressors such as excessive exercise, nutritional deficits, or psychological distress. Women vary in their susceptibility to inhibition of the reproductive axis by such stressors, but it is unknown whether this variability reflects a genetic predisposition to hypothalamic amenorrhea. We hypothesized that mutations in genes involved in idiopathic hypogonadotropic hypogonadism, a congenital form of GnRH deficiency, are associated with hypothalamic amenorrhea. METHODS We analyzed the coding sequence of genes associated with idiopathic hypogonadotropic hypogonadism in 55 women with hypothalamic amenorrhea and performed in vitro studies of the identified mutations. RESULTS Six heterozygous mutations were identified in 7 of the 55 patients with hypothalamic amenorrhea: two variants in the fibroblast growth factor receptor 1 gene FGFR1 (G260E and R756H), two in the prokineticin receptor 2 gene PROKR2 (R85H and L173R), one in the GnRH receptor gene GNRHR (R262Q), and one in the Kall-mann syndrome 1 sequence gene KAL1 (V371I). No mutations were found in a cohort of 422 controls with normal menstrual cycles. In vitro studies showed that FGFR1 G260E, FGFR1 R756H, and PROKR2 R85H are loss-of-function mutations, as has been previously shown for PROKR2 L173R and GNRHR R262Q. CONCLUSIONS Rare variants in genes associated with idiopathic hypogonadotropic hypogonadism are found in women with hypothalamic amenorrhea, suggesting that these mutations may contribute to the variable susceptibility of women to the functional changes in GnRH secretion that characterize hypothalamic amenorrhea. Our observations provide evidence for the role of rare variants in common multifactorial disease.

Sensitivity of annual mass balance gradient and Hypsometry to the changing climate: the case of Dokriani Glacier, central Himalaya, India

NASA Astrophysics Data System (ADS)

Pratap, B.

2015-12-01

The glacier mass balance is undelayed, unfiltered and direct method to assess the impact of climate change on the glaciers. Many studies suggest that some of the Himalayan glaciers have lost their mass at an increased rate during the past few decades. Furthermore, the mass balance gradient and hypsometric analysis are important to understand the glacier response towards climatic perturbations. Our long term in-situ monitoring on the Dokriani Glacier provides great insights to understand the variability in central Himalayan glaciers. We report the relationship between glacier hypsometry and annual mass balance gradient (12 years) to understand the glacier's response towards climate change. Dokriani Glacier in the Bhagirathi basin is a small (7 km2) NNW exposed glacier in the western part of central Himalaya, India. The study analysed the annual balance, mass balance gradient and length changes observed during first decade of 21st century (2007-2013) and compare with the previous observations of 1990s (1992-2000). A large spatial variability in the mass balance gradients of two different periods has been observed. The equilibrium-line altitude (ELA) was fluctuated between 5000 and 5100 m a.s.l. and the derived time averaged ELA (ELAn) and balance budget ELA (ELA0) were 5075 and 4965 m a.s.l respectively during 1992-2013. The observed time-averaged accumulation-area ratio (AARn) and balance budget AAR (AAR0) were 0.67 and 0.72 respectively during 1992-2013. The higher value of AAR comprises due to flat and broader accumulation area (4.50 km2) of the glacier. Although, having larger accumulation area, the glacier has faced strong mass wasting with average annual ablation of -1.82 m w.e. a-1 in the ablation zone as compare to residual average annual accumulation of 0.41 m w.e. a-1. Based on the annual mass balance series (12 years) Dokriani Glacier has continuous negative annual balances with monotonically negative cumulative mass loss of -3.86 m w.e with the average loss of -0.32 m w.e a-1. Dokriani Glacier also showed continues recession from 1992 to present. Snout was ascended 95 m a.s.l. from an elevation of 3870 m a.s.l. in 1992 to an elevation of 3965 m a.s.l. in 2013. The progressive retreat of the glacier affects its extension and volume and covered by continuous enhancement of debris in the lower ablation zone.

Evaluating potentials for future generation off-shore wind-power outside Norway

NASA Astrophysics Data System (ADS)

Benestad, R. E.; Haugen, J.; Haakenstad, H.

2012-12-01

With todays critical need of renewable energy sources, it is naturally to look towards wind power. With the long coast of Norway, there is a large potential for wind farms offshore Norway. Although there are more challenges with offshore wind energy installations compared to wind farms on land, the offshore wind is generally higher, and there is also higher persistence of wind speed values in the power generating classes. I planning offshore wind farms, there is a need of evaluation of the wind resources, the wind climatology and possible future changes. In this aspect, we use data from regional climate model runs performed in the European ENSEMBLE-project (van der Linden and J.F.B. Mitchell, 2009). In spite of increased reliability in RCMs in the recent years, the simulations still suffer from systematic model errors, therefore the data has to be corrected before using them in wind resource analyses. In correcting the wind speeds from the RCMs, we will use wind speeds from a Norwegian high resolution wind- and wave- archive, NORA10 (Reistad et al 2010), to do quantile mapping (Themeβl et. al. 2012). The quantile mapping is performed individually for each regional simulation driven by ERA40-reanalysis from the ENSEMBLE-project corrected against NORA10. The same calibration is then used to the belonging regional climate scenario. The calibration is done for each grid cell in the domain and for each day of the year centered in a +/-15 day window to make an empirical cumulative density function for each day of the year. The quantile mapping of the scenarios provide us with a new wind speed data set for the future, more correct compared to the raw ENSEMBLE scenarios. References: Reistad M., Ø. Breivik, H.

Long-term coastal measurements for large-scale climate trends characterization

NASA Astrophysics Data System (ADS)

Pomaro, Angela; Cavaleri, Luigi; Lionello, Piero

2017-04-01

Multi-decadal time-series of observational wave data beginning in the late 1970's are relatively rare. The present study refers to the analysis of the 37-year long directional wave time-series recorded between 1979 and 2015 at the CNR-ISMAR (Institute of Marine Sciences of the Italian National Research Council) "Acqua Alta" oceanographic research tower, located in the Northern Adriatic Sea, 15 km offshore the Venice lagoon, on 16 m depth. The extent of the time series allows to exploit its content not only for modelling purposes or short-term statistical analyses, but also at the climatological scale thanks to the peculiar meteorological and oceanographic aspects of the coastal area where this relevant infrastructure has been installed. We explore the dataset both to characterize the local average climate and its variability, and to detect the possible long-term trends that might be suggestive of, or emphasize, large scale circulation patterns and trends. Measured data are essential for the assessment, and often for the calibration, of model data, generally, if long enough, also the reference also for climate studies. By applying this analysis to an area well characterized from the meteorological point of view, we first assess the changes in time based on measured data, and then we compare them to the ones derived from the ERA-Interim regional simulation over the same area, thus showing the strong improvement that is still needed to get reliable climate models projections on coastal areas and the Mediterranean Region as a whole. Moreover, long term hindcast aiming at climatic considerations are well known for 1) underestimating, if their resolution is not high enough, the actual wave heights as well as for 2) being strongly affected by different conditions over time that are likely to introduce spurious trends of variable magnitude. In particular the different amount, in time, of assimilated data by the hindcast models, directly and indirectly affects the results, making it difficult, if not impossible, to distinguish the imposed effects from the climate signal itself, as demonstrated by Aarnes et al. (2015). From this point of view the problem is that long-term measured datasets are relatively unique, due to the cost and technical difficulty of maintaining fixed instrumental equipment over time, as well as of assuring the homogeneity and availability of the entire dataset. For this reason we are furthermore working on the publication of the quality controlled dataset to make it widely available for open-access research purposes. The analysis and homogenization of the original dataset has actually required a substantial part of the time spent on the study, because of the strong impact that the quality of the data may have on the final result. We consider this particularly relevant, especially when referring to coastal areas, where the lack of reliable satellite data makes it difficult to improve the model capability to resolve the local peculiar oceanographic processes. We describe in detail any step and procedure used in producing the data, including full descriptions of the experimental design, data acquisition assays, and any computational processing needed to support the technical quality of the dataset.

The incidence of melanoma is increasing faster than any other major cancer both in Brazil and worldwide. Southeast Brazil has especially high incidences of melanoma, and early detection is low. Exposure to ultraviolet (UV) radiation is a primary risk factor for developing melanoma. Increasing attractiveness is a major motivation among adolescents for tanning. A medical student-delivered intervention that takes advantage of the broad availability of mobile phones and adolescents' interest in their appearance indicated effectiveness in a recent study from Germany. However, the effect in a high-UV index country with a high melanoma prevalence and the capability of medical students to implement such an intervention remain unknown. In this pilot study, our objective was to investigate the preliminary success and implementability of a photoaging intervention to prevent skin cancer in Brazilian adolescents. We implemented a free photoaging mobile phone app (Sunface) in 15 secondary school classes in southeast Brazil. Medical students "mirrored" the pupils' altered 3-dimensional (3D) selfies reacting to touch on tablets via a projector in front of their whole grade accompanied by a brief discussion of means of UV protection. An anonymous questionnaire capturing sociodemographic data and risk factors for melanoma measured the perceptions of the intervention on 5-point Likert scales among 356 pupils of both sexes (13-19 years old; median age 16 years) in grades 8 to 12 of 2 secondary schools in Brazil. We measured more than 90% agreement in both items that measured motivation to reduce UV exposure and only 5.6% disagreement: 322 (90.5%) agreed or strongly agreed that their 3D selfie motivated them to avoid using a tanning bed, and 321 (90.2%) that it motivated them to improve their sun protection; 20 pupils (5.6%) disagreed with both items. The perceived effect on motivation was higher in female pupils in both tanning bed avoidance (n=198, 92.6% agreement in females vs n=123, 87.2% agreement in males) and increased use of sun protection (n=197, 92.1% agreement in females vs n=123, 87.2% agreement in males) and independent of age or skin type. All medical students involved filled in a process evaluation revealing that they all perceived the intervention as effective and unproblematic, and that all pupils tried the app in their presence. The photoaging intervention was effective in changing behavioral predictors for UV protection in Brazilian adolescents. The predictors measured indicated an even higher prospective effectiveness in southeast Brazil than in Germany (>90% agreement in Brazil vs >60% agreement in Germany to both items that measured motivation to reduce UV exposure) in accordance with the theory of planned behavior. Medical students are capable of complete implementation. A randomized controlled trial measuring prospective effects in Brazil is planned as a result of this study. ©Titus Josef Brinker, Marlene Heckl, Martina Gatzka, Markus V Heppt, Henrique Resende Rodrigues, Sven Schneider, Wiebke Sondermann, Carolina de Almeida e Silva, Michael C Kirchberger, Joachim Klode, Alexander H Enk, Sarah Knispel, Christof von Kalle, Ingo Stoffels, Dirk Schadendorf, Yasuhiro Nakamura, Stefan Esser, Aisllan Assis, Breno Bernardes-Souza.

In nature, molecules exploit interaction with their environment to realize complex functionalities on the nanometer length scale. Physical, chemical and/or biological specificity is frequently achieved by the switching of molecules between microscopically different states. Paradigmatic examples are the energy production in proton pumps of bacteria or the signal conversion in human vision, which rely on switching molecules between different configurations or conformations by external stimuli. The remarkable reproducibility and unparalleled fatigue resistance of these natural processes makes it highly desirable to emulate nature and develop artificial systems with molecular functionalities. A promising avenue towards this goal is to anchor the molecular switches at surfaces, offering new pathways to control their functional properties, to apply electrical contacts, or to integrate switches into larger systems. Anchoring at surfaces allows one to access the full range from individual molecular switches to self-assembled monolayers of well-defined geometry and to customize the coupling between molecules and substrate or between adsorbed molecules. Progress in this field requires both synthesis and preparation of appropriate molecular systems and control over suitable external stimuli, such as light, heat, or electrical currents. To optimize switching and generate function, it is essential to unravel the geometric structure, the electronic properties and the dynamic interactions of the molecular switches on surfaces. This special section, Molecular Switches at Surfaces, collects 17 contributions describing different aspects of this research field. They analyze elementary processes, both in single molecules and in ensembles of molecules, which involve molecular switching and concomitant changes of optical, electronic, or magnetic properties. Two topical reviews summarize the current status, including both challenges and achievements in the field of molecular switches on metal surfaces, focusing on electronic and vibrational spectroscopy in one case and scanning tunneling microscopy studies in the other. Original research articles describe results in many aspects of the field, including: Self-assembly, self-organization, and controlled growth of molecular layers on various substrates. Highly-ordered arrays provide model systems with extraordinary structural properties, allowing one to adjust interactions between molecules and between molecule and substrate, and can be robustly prepared from solution, an essential prerequisite for applications. Conformational or electronic switching of molecules adsorbed at metal and semiconductor surfaces. These studies highlight the elementary processes governing molecular switching at surfaces as well as the wide range of possible stimuli. Carbon-based substrates such as graphene or carbon nanotubes. These substrates are attractive due to their effective two-dimensionality which implies that switching of adsorbed molecules can effect a significant back-action on the substrate. Mechanisms of conformational switching. Several contributions study the role of electron-vibron coupling and heating in current-induced conformational switching. We hope that the collection of articles presented here will stimulate and encourage researchers in surface physics and interfacial chemistry to contribute to the still emerging field of molecular switches at surfaces. We wish to acknowledge the support and input from many colleagues in preparing this special section. A significant part of this work has been conducted in the framework of the Sonderforschungsbereich 658 Elementary Processes in Molecular Switches at Surfaces of the Deutsche Forschungsgemeinschaft, to which we are grateful for financial support.

This topical issue of Physica Scripta collects selected peer-reviewed contributions based on invited and contributed talks and posters presented at the 15th Central European Workshop on Quantum Optics (CEWQO) which took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu). On behalf of the whole community took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu, cewqo08.phy.bg.ac.yu). On behalf of the whole community of the workshop, we thank the referees for their careful reading and useful suggestions which helped to improve all of the submitted papers. A brief description of CEWQO The Central European Workshop on Quantum Optics is a series of conferences started informally in Budapest in 1992. Sometimes small events transform into important conferences, as in the case of CEWQO. Professor Jozsef Janszky, from the Research Institute of Solid State Physics and Optics, is the founder of this series. Margarita Man'ko obtained the following information from Jozsef Janszky during her visit to Budapest, within the framework of cooperation between the Russian and Hungarian Academies of Sciences in 2005. He organized a small workshop on quantum optics in Budapest in 1992 with John Klauder as a main speaker. Then, bearing in mind that a year before Janszky himself was invited by Vladimir Buzek to give a seminar on the same topic in Bratislava, he decided to assign the name 'Central European Workshop on Quantum Optics', considering the seminar in Bratislava to be the first workshop and the one in Budapest the second. The third formal workshop took place in Bratislava in 1993 organized by Vladimir Buzek, then in 1994 (Budapest, by Jozsef Janszky), 1995 and 1996 (Budmerice, Slovakia, by Vladimir Buzek), 1997 (Prague, by Igor Jex), 1999 (Olomouc, Czech Republic, by Zdenek Hradil), 2000 (Balatonfüred, Hungary, by Jozsef Janszky ), 2001 (Prague, by Igor Jex), 2002 (Szeged, Hungary, by Mihaly Benedict), 2003 (Rostock,Germany, by Werner Vogel and Sascha Wallentowitz), 2004 (Trieste, Italy, by Naseem Rahman and Sascha Wallentowitz), 2005 (Bilkent, Ankara, by Alexander Shumovsky), 2006 (Vienna, by Helmut Rauch), 2007 (Palermo, Italy, by Antonino Messina) and 2008 (Belgrade, by Mirjana Bozic). The CEWQO series developed in two directions following the rapid development of quantum optics and the transitional development of the scientific collaboration of Central European researchers with researchers from old and new emerging Central European countries, and from all over the world. The topics discussed at CEWQO 08 were divided into ten groups that aimed to cover the broad scope of modern quantum optics: Fundamental aspects of quantum optics and quantum mechanics Single photons and photon pairs Cavity and circuit QED Atoms in intense fields Neutron, atom and molecular quantum optics Quantum gases and fluids Coherence, entanglement and decoherence Optical properties of condensed matter and nanostructures Open quantum systems and chaos Quantum information processing Central European Workshops on Quantum Optics realize and are consistent with a wider idea, and a social, economical, cultural and political program promoted since 1989 by the Central European Initiative (CEI), the main goal of which was to help transition countries in Central Europe to become closer to the EU. The resulting support of the CEI, first obtained thanks to the scientific reputation, organizing activities, and efforts of Helmut Rauch, has been very important for the organization of the CEWQO in recent years, particularly in 2008. The support of the Sixth and Seventh Framework Programs of the European Commission was also very important. A short review of papers in this topical issue A principal role in this topical issue is played by the photon. Vuletic et al describe the mapping of the photon-polarization state onto a single collective-spin excitation (magnon) shared between two atomic ensembles. A heralded quantum memory based on this mapping is demonstrated. Dodonov derives a formula which predicts a photon generation rate in a cavity due to strong variations of the complex dielectric function in a thin layer near an ideally conducting wall (simulation of the dynamic Casimir effect). Skenderovic reports how photons from two femptosecond laser pulses prepare a large molecule in a coherent superposition of vibrational states. The time evolution of this state is interrogated with a third (delayed) pulse which creates a fourth wave, the signal, giving information on the molecular dynamics. Dimitrova et al present lecture demonstrations of interference and quantum erasing with single photons. By considering electromagnetic energy flow lines as photon paths Davidovic et al explain the emergence of an interference pattern in the process of the accumulation of single photon events behind an interference grating. Atoms in a cavity, atom-atom interactions, interactions of atoms with photons and macroscopic bodies is the next important topic in this topical issue. Khanbekyan et al deal with the problem of the spontaneous emission of an excited atom in a high-Q cavity and investigate the regime when the emitted photon belongs to a wave packet simultaneously located inside and outside the cavity. Sambale et al study the resonant Casimir-Polder potential of an excited atom in front of meta-material half-space and show that for long distances it exhibits attenuated oscillations, while close to the surface the potential becomes attractive or repulsive. Buhmann et al study the nonequilibrium Casimir-Polder force on an atom prepared in an incoherent superposition of internal energy-eigenstates, which is placed in a magnetoelectric environment of nonuniform temperature. Lazarou et al discuss how two atoms, interacting with a single cavity, can be coherently evolved into an entangled state when they are controlled by a sequence of Gaussian pulses, named frequency chirps. Bougouffa et al report on field quantization between two parallel conducting plates (modifications of the decay rate between such plates) and the three-level Jaynes-Cummings dynamics in the single-mode regime. Tomas studies the interaction between two atoms, one excited and the other in its ground state near the interface between two media. It is shown that the nonretarded van der Waals force gets enhanced by almost three orders of magnitude at the surface mode resonance. Vuskovic et al write about the plasma treatment of a bulk Nb surface which is very efficient for producing high-Q factor microwave cavities. Nemeth et al review the theory and experiments of the coherently pumped micromaser. With varied atomic inversion in a coherently pumped micromaser, a sudden switch occurs between two distinctively different field states, with high and low photon numbers. Moi et al show that alkali-metal atoms adsorbed either in organic films or in porous glass are released into the vapor phase (desorbed) under illumination, the action of many photons. Several papers are devoted to matter-wave interference and quantum fluids. By analyzing unavoidable quantum losses as they appear in neutron phase-echo and spin rotation experiments, Rauch concludes that basic quantum irreversibility exists in neutron interferometry. Rauch also shows how entanglement effects in a single particle system demonstrate quantum contextuality, and then argues that a quantum system carries much more information than is usually extracted. The time evolution of the wave function of an atom hit by a photon in a three-grating interferometer is used by Arsenovic et al to interpret the intriguing results of the corresponding experiment by Chapman et al. Grujic et al demonstrate dark Raman resonance due to Ramsey interference in a spatially separated pump and probe laser beams co-propagating through a pure 87Rb vapor cell. Obtained EIT profiles are explained by solving Bloch's equations for an atom in a magnetic field moving through pump and probe laser regions. Gawlik et al present results of experiments on finite-temperature Bose-Einstein condensate of 87Rb atoms in a magnetic trap. In the Thomas-Fermi (TF) regime, the condensate dynamics has a hydrodynamic character. The dynamics of non-TF condensates reflect the interaction between BEC and non-condensed thermal atoms. Atoms in intense fields is the subject of several papers. Gainutdinov et al show that the contribution to the radiative shift of the side bands of the Mollow spectrum is very significant. Using Gell-Mann, Low S-matrix formalism, and QED, Glushkov et al present an approach to study multiphoton processes during the interaction of an atom with a realistic intense laser field. The paper by Khetselius is devoted to two related problems: the calculation of the atomic hyperfine structure of the Li-like ions and an estimation of the effectiveness of the three-step scheme of isotope separation for the case of Cs isotopes. Vvedenskii et al present the results concerning the excitation of a residual quasi-dc current in the plasma, which are based on the solution of the time-dependent Schrödinger equation for the hydrogen atom in a few-cycle laser pulse. Information processing is one of the important aspects of this issue and it is considered in several papers. M Man'ko et al presented a new notion of tomographic entropy and new entropic uncertainty relations applied to the problem of light propagation in optical fibers. Nonlinearity in the quantum-information processing is considered in the paper by Chirkin et al. D'Arrigo et al investigated a very specific semiclassical Hamiltonian model of a quantum memory channel. They evaluated the performance of the three-qubit code error correcting code by means of entanglement fidelity. The fundamental aspects of quantum optics are the subject of several papers, namely, Bell's inequalities are studied in the paper by Andreev, the star-product quantization scheme was discussed by O Man'ko, and probabilistic representation was investigated in the paper by Adam et al. In the paper by V Man'ko et al the diagonal representation of the density operator (usually called P-function of Glauber-Sudarshan) is related to the star-product quantization method and to the tomographic-probability representation of quantum states. Laskowski et al suggest an elegant geometrical criterion for the separability, which is based on the local correlation measurements readily available in the laboratory. Mizrahi describes a method to derive the Pauli-Schrödinger equation starting from a simple model of a qubit carried by a massive particle. By analyzing unavoidable quantum losses as they appear in neutron phase-echo and spin rotation experiments, Rauch concludes that basic quantum irreversibility exists in neutron interferometry. Rauch also shows how entanglement effects in a single particle system demonstrate quantum contextuality, and then argues that a quantum system carries much more information than is usually extracted. Kupczynski advocates various statistical tests which could be used to search for a fine structure in experimental data in order to answer the question: is quantum theory predictably complete? For an ion confined within a Paul trap, Mihalcea constructs an invariant operator based on the Lews and Riesenfeld approach and determines the spectrum of the quasienergy operator. Popov et al construct pair-coherent states of the Barut-Girardello kind for two noninteracting subsystems of pseudoharmonic oscillators and examine their statistical properties in different regions of parameters. The property of entanglement, considered to be the most intriguing property of composite quantum systems, has been an important research subject in recent years. It is considered to be a possible resource for quantum computation and communication. Therefore, a substantial number of papers in this topical issue is devoted to entanglement. Leon et al write that two-photon emission from two atoms initially excited in a common electromagnetic vacuum may generate atom-atom entanglement. Dömötör et al elucidate a connection between entanglement and coherent states. Earlier they proved that in the symmetric subspace of a system of N qubits a pure state is not globally entangled, if and only if, it is a coherent state. Here they extend this proof to a system of N 'quKits' (subsystems of arbitrary finite dimension K). Napoli et al compute exactly localizable entanglement as a function of temperature for the system of three interacting spins in a thermal state. Isar considers entanglement in open quantum dynamics by studying the system of two independent oscillators interacting with the general environment. He proposes some special parameters of the environment that manifest interesting properties (e.g., the environment is entangling initially separable states). Lindén et al study the decay of entanglement in rings of qubits that live in the Markov environment. They use the entanglement of formation as the measure whose time evolution announces (or not) the decay. Jivulescu et al consider the time evolution of a spin-1/2 particle nonuniformly coupled through the Heisenberg interaction to the environment composed of N spins. Considering arbitrary initial conditions the authors determine a numerically manipulative general solution from which information on full dynamics may be extracted. Ferraro et al investigate the entanglement evolution of two qubits interacting with a common environment through a Heisenberg XX mechanism and show that the phenomena of entanglement hidden death and entanglement hidden revival take place. Stochastic processes have been very important in quantum optics. Pascazio et al review and compare three algorithms for the generation of sequences of symmetric stable Levy random variables. They draw conclusions on the efficiency of the algorithms used and on some applications in quantum optics. Hul et al report on the possibilities of explaining the statistical properties of the spectra of irregular quantum systems by invoking the random matrix theory. The authors calculated the spectra, spectral correlation functions, and the distributions of avoided crossings, for two types of idealized model of one-dimensional quantum wires forming a quantum graph. Sirko et al present the experimental study of microwave networks displaying an irregular hexagonal structure. In a sense, these networks model quantum graphs with special properties. Kiss et al consider the recurrence of quantum walks on lattices by studying the properties of the generalized Polya number. The properties of this number are compared for classical and quantum cases. A number of interesting papers are devoted to the optical properties of condensed matter and nanostructures. Gorelik derives analytical expressions for photonic dispersion law in 3D photonic crystals filled by dielectrics or metal. Nemilentsau et al evaluate the photon density of states near a single-wall finite length carbon nanotube. The authors found definite singularities in the density of photon states that may be observable in light-matter interaction, thermal radiation distribution, and micromechanical phenomena related to Casimir forces. Perinova et al pay attention to the interesting relationship between microscopic and macroscopic approaches to the quantization of the electromagnetic field in the medium. They examine the problem of a source atom radiating into a dielectric. Radovanovic et al present an extended approach for estimating the tunneling times through all linear materials, including metamaterials having a negative refractive index. Vasic et al describe the optical design of 2D confined structures with metamaterial layers which is based on coordinate transformations. Using the Green's functions method, Ilic et al analyze the influence of boundaries of the molecular ultrathin film on exciton dispersion law. Jeknic-Dugic proposes the model of optically induced transitions in an electronic subsystem of a bio-molecule that is able to describe relatively slow conformational transitions of a bio-molecule. Stef et al present their goal to grow good quality YbF3-doped and PbF2-codoped CaF2 crystals with high divalent Ytterbium content for investigating the influence of Pb2+ ions on the valence conversion, on the dielectric and optical absorption spectra. Vasile et al present the fabrication and SEM and photoluminescence characterization of zinc gallate doped with Eu and Er ions. The results could be important for photonic applications of spinels. Vasiljevic et al present the process of production of microlenses by irradiation of a tot'hema eosin sensitized gelatin (TESG) layer with a laser beam (2nd Nd:YAG harmonic, 532 nm). Microlenses chemically processed after production with 10% alum solution had near diffraction limited performance. The production and application of microlenses are fast expanding because they are increasingly used in biomedical and general optics. Prizes for the poster presentations Authors under 35 years of age were invited to take part in the poster competition. Two first prizes EX-AEQUOAE were awarded to Zoran Grujic from the Institute of Physics, Belgrade, Serbia, for the poster 'Numerical simulation of Raman-Ramsey effects induced by thermal motion of rubidium atoms' and to Andrey Popov from Altai State Technical University, Bernaul, Russia, for the poster 'Beryllium atoms in intense fields'. The third prize was awarded to Alex Crosse from Imperial College, London, UK, for the poster 'Quantum electrodynamics in absorbing nonlinear media'. Members of the Jury were: Mirjana Bozic (Chairperson), Victor Dodonov, Margarita Man'ko, Helmut Rauch, Saverio Pascazio, Richard Tanas and Philip Walther. Sponsors of the awards were the Institute of Physics, Belgrade, European Physical Journal (EPJ) and John Wiley and Sons. CEWQO 2009 and 2010 The 16th Central European Workshop on Quantum Optics was held in Turku, Finland, 23-27 May 2009. CEWQO09 was chaired by Professor Kalle-Antti Suominen (http://www.congress.utu.fi/cewqo2009). The conference site is the new ICT building at chaired by Professor Kalle-Antti Suominen (http://www.congress.utu.fi/cewqo2009, www.congress.utu.fi/cewqo2009). The conference site was the new ICT building at the University of Turku campus area and the Viking Line ferry boat. Turku is the central city of historical Finland established on the mouth of the river Aura in the 13th century. It is the birthplace of Finnish academic life, since the Academy of Turku was established there in 1640. In 2011, Turku will be one of the cultural capitals of Europe. The city has a strong maritime tradition and is shielded from the Baltic sea by a large and beautiful archipelago. The 17th Central European Workshop on Quantum Optics will be held in 2010 in St Andrews, UK. It will be chaired by Professors Ulf Leonhardt and Natalia Korolkova from the School of Physics and Astronomy, University of St Andrews. St Andrews is home to the first university of Scotland, the third-oldest in the English-speaking world, and is the home of golf. It remains a charming, eccentric seaside town that is sufficiently secluded - the ideal place for a stimulating and thought-provoking conference.

It is not easy to assess, or even to describe correctly a long and distinguished career that started about the time when I was born. In 1964 Stig Stenholm got both an engineering degree at the Helsinki University of Technology (HUT), and an MSc degree (in Mathematics) at the University of Helsinki. The two degrees demonstrate Stig's ability to understand both complex mathematics and experimental physics. Statistical physics or rather, quantum liquids, was the field in which Stig got his DPhil at Oxford in 1967, under the guidance of Dirk ter Haar. It is interesting that together they worked on studying fermions in a bosonic background [1]; at the time this meant, of course, 3He atoms as impurities in 4He liquid, but nowadays one would immediately connect such systems to the physics of cold atomic gases. The postdoctoral period in 1967-1968 at Yale University brought Stig in contact with Willis Lamb and laser physics [2]. Back in Finland, Stig's career in the 1970s was dominated by theoretical studies of gas lasers, especially pressure and collision effects on spectral lines and saturation spectroscopy, together with his first PhD student, Rainer Salomaa. A professorship at the University of Helsinki came in 1974, and in 1980 an important era started as Stig became the scientific director of the Research Institute for Theoretical Physics (TFT). At that time he also developed the semiclassical theory of laser cooling especially with Juha Javanainen. The laser spectroscopy work led to a textbook in 1984 [3], and the semiclassical laser cooling theory was summarized in a review article in 1986 [4]. These were not, of course, his only interests, as he also worked on free-electron lasers, ring-laser gyroscopes, multiphoton processes and quantum amplifiers. In an article written in 1990 in honour of Olli Lounasmaa [5], the founder of the famous Low Temperature Laboratory at HUT, Stig mentions that one of his most memorable achievements was acting as a bridge between the Western and Soviet laser cooling communities. In neutral Finland, accessible to both parties, he organized informal workshops that crucially sped the development of laser cooling. The importance of these meetings is highlighted in Bill Phillips' Nobel lecture in 1997 [6]. However, as the emphasis in laser cooling moved from a semiclassical description to quantum theory, Stig started to look for new avenues of research. My contact with Stig came when I went to see him for an MSc thesis topic. This involved polarization spectroscopy and modelling of an experiment performed by the laser spectroscopy group (Birger Ståhlberg) at the University of Helsinki. Without knowing anything about quantum optics I then found myself immediately in one of the Finnish-Soviet workshops on quantum electronics in the small town of Porvoo slightly east of Helsinki. There I met people like Juha Javanainen, Peter Knight, Axel Schenzle and Vladimir Chebotayev, and my own career in quantum optics began, working on the mathematics of the Landau-Zener model and how to apply it and other such models in molecular excitation by femtosecond pulses for my PhD thesis. This work was done together with Barry Garraway, who was a postdoc in Helsinki in the early 1990s. The Finnish-Soviet meetings continued for a while, and in 1990 we even got to travel to Novosibirsk (and back, too). During its existence (1964-1996), the Research Institute of Theoretical Physics (TFT) had a tremendous impact on physics in Finland. Short and long stays by visitors provided a unique and high-level environment for local researchers, the research fields covered a wide range of physics, and for many Finns returning from abroad it provided a place to stay until something more permanent turned up. Thus many researchers who later became professors had, at some point in their career, a connection with TFT. As a director Stig was very broad-minded and without this the happy atmosphere of TFT could not have existed. In the 1980s young researchers such as Marc-Andre Dupertuis and Steve Barnett worked with Stig at TFT, and in the 1990s it was the turn of Barry Garraway, Ilkka Tittonen and Nikolay Vitanov among others. For his work in 1992-1997 Stig Stenholm received the prestigious Academy of Finland Professorship which provided him with valuable research funds. My graduation in 1992 was followed by Mackillo Kira in 1995 and Päivi Törmä in 1996. Following developments in the field, in the mid-1990s Stig started to work on Bose-Einstein condensation and quantum information. Later he had a Humboldt fellowship, with stays in Germany shared by the Universities at Konstanz (Jürgen Mlynek) and Ulm (Wolfgang Schleich). Unfortunately, the University of Helsinki decided to replace TFT and a corresponding experimental particle physics institute with a new institute, which was mostly seen as the Finnish front-end for CERN collaboration; in 1997 the Helsinki Institute of Physics (HIP) was started. Although the activities of TFT still existed in the theory section of HIP, many things and especially the atmosphere were changed and in 1997 this partly led Stig to accept a position at the Royal Institute of Technology in Stockholm, Sweden, where two of his Finnish students, Patrik Öhberg and Erika Andersson graduated shortly after the move. I moved to HIP at the time, but left for a position in Turku in 2000, and the quantum optics project was finally switched off at HIP in 2003—only later it was found that quantum optics had provided the Institute with its most cited papers, propelling it into the top 5 percent most cited institutes in its field (especially thanks to Norbert Lütkenhaus and his work on quantum cryptography). The time in Stockholm was fruitful for Stig scientifically, but he also became a member of the Royal Swedish Academy of Sciences, and although Nobel committee papers remain secret for 50 years, it is likely that he had a hand in its activities. In 2005 we jointly published a textbook on quantum information [7] and in Stockholm he had, again, very successful postdocs such as Ulf Leonhardt. Finally, in 2005, Stig Stenholm retired, although he is still active, writing papers, taking part in conferences and making research visits. We honoured his 70th birthday at the CEWQO2009 conference, and hope that the future provides us with further opportunities for such events. Looking at the obituary of Dirk ter Haar, I see that his style with students reminds me of Stig's approach. In my opinion, Stig expects independence and initiative from a student, giving perhaps a broad topic in which the student is expected to find his or her own way, whilst working perhaps with a postdoc. Juha Javanainen has talked about the 'sink or swim' style (not referring to Stig, though). There is a famous series of children's books about Moomin trolls by Tove Jansson (another Swedish-speaking Finn like Stig). In one of them, the Moomin find in early spring a small flower in a patch of land uncovered by snow, pushing its way up. One of them wants to cover it against frost during the night, but another says 'Don't, it'll fare better later if it has some difficulties at first'. At CEWQO2009 Stig gave the full list of his finished PhD students: Rainer Salomaa (1973), Temba Dlodlo (1980), Juha Javanainen (1980), Markus Lindberg (1985), Matti Kaivola (1985), Birger Ståhlberg (1985), Kalle-Antti Suominen (1992), Mackillo Kira (1995), Päivi Törmä (1996), Asta Paloviita (1997), Patrik Öhberg (1998), Martti Havukainen (1999), Erika Andersson (2000), Pawel Piwnicki (2001), Åsa Larson (2001), Markku Jääskeläinen (2003), and Jonas Larson (2005). One should also mention Erkki Kyrölä, who eventually graduated at Rochester and Olli Serimaa, who never graduated but published some important early-stage laser cooling work. As a final note I must mention a passion that Stig and I share, namely books. I have nearly 400 professional physics and mathematics books, but I am certain that the size of Stig's library exceeds this by far. And this passion is not solely limited to professional books, as one can see, for example, from the references in Stig's article for these proceedings. His interests cover philosophy, history, science fiction and many other topics, and more importantly, the books in his library also get read. In modern times of narrow specialization, high efficiency and h-index, his approach to science and culture sets an example that is worth following.
