The Basic Documentation for Psycho‐Oncology (PO‐Bado): An innovative tool to combine screening for psychological distress and patient support at cancer diagnosis
Authors: Stadelmaier Nena , Duguey‐Cachet Odile , Saada Yael , Quintard Bruno 
Published: October 2013

AbstractObjectivesThe Basic Documentation for Psycho‐Oncology (PO‐Bado) is a semi‐directive instrument for assessing psychosocial difficulties in cancer patients. It is based on subjective status and not on degree of symptom severity. Our objectives were to assess whether use of the PO‐Bado during post‐cancer‐diagnosis consultations improves the quality of communication by establishing a supportive relationship between nurses and patients and to assess nurses' satisfaction of their communication skills.MethodsData were collected from post‐diagnosis ‘bad‐news’ consultations across four Cancer treatment centres in South West France. Eleven nurses who had never used the PO‐Bado (‘inexperienced group’) received training on the instrument (short‐form). Twenty‐one pre‐training consultations without the PO‐Bado were recorded and compared with 21 post‐training consultations with the PO‐Bado. Twenty consultations with four nurses with experience using the PO‐Bado (‘experienced group’) were included for between‐group comparisons. Nurses' satisfaction was evaluated through semi‐directive consultations at the end of the study and completed by a visual analogue scale.ResultsWe transcribed and analysed 62 consultations. We observed greater use of techniques encouraging patient expression in consultations with PO‐Bado‐experienced nurses (p < 0.01); after PO‐Bado training for ‘inexperienced’ nurses (p < 0.05) and less use of non‐encouraging techniques after PO‐Bado training for ‘inexperienced’ nurses (p < 0.01). Nurses felt more satisfied with their communications skills after PO‐Bado training and stated that they felt more competent, particularly for referrals to psychologists.ConclusionsThe PO‐Bado is beneficial for the quality of the communication between nurses and patients at bad‐news delivery consultations and for the satisfaction of nurses with regard to their relational skills.

Morphology, Sorting and Microclimates of Relict Sorted Polygons, Krkonoše Mountains, Czech Republic
Authors: Křížek Marek , Uxa Tomáš 
Published: October 2013

ABSTRACTThe influence of past microclimates on the morphology and distribution of clasts is considered for relict large‐scale sorted polygons in the Krkonoše Mountains (Czech Republic). Sixty‐two sorted polygons with an average length of 194 cm and an average height of 21.5 cm were measured at four sites on Mt Luční hora, at elevations of 1455 to 1555 m asl. The polygons consist of tabular clasts with a mean length of 11 cm at the borders and 5 cm in the interiors. Smaller polygons are better sorted because of the shorter distances for the clasts to reach their borders. Polygons with greater relative height are better sorted due to more intensive slope processes associated with differential frost heaving. Better sorted and more domed polygons at higher altitudes suggest more severe and longer‐lasting microclimates suitable for the development of sorted polygons. The altitudinal gradient in polygon morphology and sorting suggests the dominant role of microclimate in the periglacial environment of the summit area of the Krkonoše Mountains during the Last Glacial/Holocene period. Polygon development probably involves positive feedback between morphology and frost susceptibility, driven by microclimate. The proposed method for evaluating frost sorting allows for rapid non‐invasive assessment of sorting using modern methods including high‐resolution remote sensing (especially terrestrial photogrammetry).

Influence of Meteorological Elements on Changes in Active‐Layer Thickness in the Bellsund region, Svalbard
Authors: Marsz Andrzej A. , Styszyńska Anna , Pękala Kazimierz , Repelewska‐Pękalowa Janina 
Published: October 2013

ABSTRACTMeasurements of active‐layer thickness (ALT) at seven locations on Calypsostranda, Svalbard (CALM Site P1), over 1986–2009, are used to estimate the influence of cloudiness, precipitation, air temperature, the Arctic Oscillation (AO) and the North Atlantic Oscillation (NAO). Between 1986 and 2002, ALT amounted to 118 ± 14 cm and did not show any significant trend. During 2002–06, ALT increased rapidly (12.6 cm yr‐1) to a maximum of ~ 174 cm in 2006 and 2007. In 2008 and 2009, ALT decreased. No statistically significant correlations were determined between ALT and monthly precipitation and cloudiness at Barentsburg, Hornsund and Svalbard Airport stations. There were, however, very strong and highly significant (p < 0.001) relationships with air temperatures in May and June (the strongest association being with Svalbard Airport). The influence of air temperature in May and June on ALT is indirect; it regulates the time of the melt of snow cover, which determines the duration of the ground‐warming period. Using statistical relationships between ALT and air temperature at Svalbard Airport, the time series of ALT at Calypsostranda is reconstructed from 1911 to 2010. It was also found that the AO and the NAO did not significantly affect ALT and air temperature on western Spitsbergen. Copyright © 2013 John Wiley & Sons, Ltd.
The dataset for protein–RNA binding affinity
Authors: Yang Xiufeng , Li Haotian , Huang Yangyu , Liu Shiyong 
Published: October 2013

AbstractWe have developed a non‐redundant protein–RNA binding benchmark dataset derived from the available protein–RNA structures in the Protein Database Bank. It consists of 73 complexes with measured binding affinity. The experimental conditions (pH and temperature) for binding affinity measurements are also listed in our dataset. This binding affinity dataset can be used to compare and develop protein–RNA scoring functions. The predicted binding free energy of the 73 complexes from three available scoring functions for protein–RNA docking has a low correlation with the binding Gibbs free energy calculated from Kd. © 2013 The Protein Society
Characterization of multiple‐herbicide‐resistant Italian ryegrass (Lolium perenne spp. multiflorum)
Authors: Liu Mingyang , Hulting Andrew G , Mallory‐Smith Carol A 
Published: October 2013

AbstractBACKGROUNDMultiple‐herbicide resistance in Lolium perenne spp. multiflorum has evolved in many areas in Oregon. To manage the resistant populations, the resistance patterns must be determined. In this study, a population (CT) suspected to be resistant to sulfometuron and hexazinone was collected from a Christmas tree plantation.RESULTSThe CT population is resistant to at least six herbicides with four different mechanisms of action: atrazine (>16‐fold), diuron (2.4‐fold), glyphosate (7.4‐fold), hexazinone (3.1‐fold), imazapyr (1.8‐fold) and sulfometuron (>16‐fold). Two mutations, Trp‐591‐Leu and Ser‐264‐Gly, were identified in the acetolactate synthase (ALS) and psbA gene respectively. No previously reported mutation in the 5‐enolpyruvylshikimate‐3‐phosphate synthase (EPSPS) gene was found. Less shikimic acid accumulated in the CT plants than in the susceptible plants after treatment with glyphosate at 0.6 kg AE ha−1.CONCLUSIONThis study suggests that the multiple resistance patterns of Lolium perenne spp. multiflorum populations can be complex, but that chemical control options to manage these populations exist. These remaining chemical options should be integrated with non‐chemical management strategies to slow the spread of multiple‐resistant biotypes in agroecosystems. © 2013 Society of Chemical Industry
A comparison of statistical methods for combining relative bioactivities from parallel line bioassays
Authors: Mzolo Thembile , Hendriks Marga , van den Heuvel Edwin 
Published: October 2013

AbstractThis paper compares the ordinary unweighted average, weighted average, and maximum likelihood methods for estimating a common bioactivity from multiple parallel line bioassays. Some of these or similar methods are also used in meta‐analysis. Based on a simulation study, these methods are assessed by comparing coverage probabilities of the true relative bioactivity and the length of the confidence intervals computed for these methods. The ordinary unweighted average method outperforms all statistical methods by consistently giving the best coverage probability but with somewhat wider confidence intervals. The weighted average methods give good coverage and smaller confidence intervals when combining homogeneous bioactivities. For heterogeneous bioactivities, these methods work well when a liberal significance level for testing homogeneity of bioactivities is used. The maximum likelihood methods gave good coverage when homogeneous bioactivities were considered. Overall, the preferred methods are the ordinary unweighted average and two weighted average methods that were specifically developed for bioassays. Copyright © 2013 John Wiley & Sons, Ltd.
Consensus of heterogeneous first‐ and second‐order multi‐agent systems with directed communication topologies
Authors: Feng Yuanzhen , Xu Shengyuan , Lewis Frank L. , Zhang Baoyong 
Published: October 2013

SummaryIn this paper, we consider the consensus problem for heterogeneous multi‐agent systems composed of some first‐order and some second‐order dynamic agents in directed communication graphs. Consensus protocols are proposed for the second‐ and first‐order dynamic agents, respectively. Under certain assumptions on the control parameters, for fixed communication topologies, necessary and sufficient conditions for consensus are given, and the consensus values of all agents are established. For switching topologies, sufficient conditions are given for all agents to reach consensus. Finally, simulation examples are presented to demonstrate the effectiveness of the proposed methods.

Limit distribution of the coefficients of polynomials with only unit roots
Authors: Hwang Hsien‐Kuei , Zacharovas Vytas 
Published: October 2013

AbstractWe consider sequences of random variables whose probability generating functions have only roots on the unit circle, which has only been sporadically studied in the literature. We show that the random variables are asymptotically normally distributed if and only if the fourth central and normalized (by the standard deviation) moment tends to 3, in contrast to the common scenario for polynomials with only real roots for which a central limit theorem holds if and only if the variance is unbounded. We also derive a representation theorem for all possible limit laws and apply our results to many concrete examples in the literature, ranging from combinatorial structures to numerical analysis, and from probability to analysis of algorithms. © 2013 Wiley Periodicals, Inc.

AbstractLet denote the diamond graph, formed by removing an edge from the complete graph K4. We consider the following random graph process: starting with n isolated vertices, add edges uniformly at random provided no such edge creates a copy of . We show that, with probability tending to 1 as , the final size of the graph produced is . Our analysis also suggests that the graph produced after i edges are added resembles the uniform random graph, with the additional condition that the edges which do not lie on triangles form a random‐looking subgraph. © 2013 Wiley Periodicals, Inc.

Strong spatial mixing of list coloring of graphs
Authors: Gamarnik David , Katz Dmitriy , Misra Sidhant 
Published: October 2013

AbstractThe property of spatial mixing and strong spatial mixing in spin systems has been of interest because of its implications on uniqueness of Gibbs measures on infinite graphs and efficient approximation of counting problems that are otherwise known to be #P hard. In the context of coloring, strong spatial mixing has been established for Kelly trees in (Ge and Stefankovic, arXiv:1102.2886v3 (2011)) when where q the number of colors, Δ is the degree and .. is the unique solution to . It has also been established in (Goldberg et al., SICOMP 35 (2005) 486–517) for bounded degree lattice graphs whenever for some constant β, where Δ is the maximum vertex degree of the graph. We establish strong spatial mixing for a more general problem, namely list coloring, for arbitrary bounded degree triangle‐free graphs. Our results hold for any whenever the size of the list of each vertex v is at least where is the degree of vertex v and β is a constant that only depends on α. The result is obtained by proving the decay of correlations of marginal probabilities associated with graph nodes measured using a suitably chosen error function. © 2013 Wiley Periodicals, Inc.

AbstractThis paper documents the results of a joint research project dealing with the loading of formwork systems used with highly flowable concretes. First calculation approaches concerning the pressure of fresh concrete on vertical formwork were developed on the basis of the investigations conducted on the material behaviour of highly flowable concretes. In doing so, construction management questions regarding, for instance, process design and quality assurance in the application of highly flowable concretes were also investigated. Different scientists from German research institutes collaborated in a research group to pool their knowledge in the field of the pressure of fresh concrete. Because of the extent and complexity of the tasks to be tackled, the joint research project was divided into five subprojects (A to E), which were performed by the research institutes according to their individual respective capacities.

Published: October 2013

ABSTRACTObjectivesA specified anatomical degree of prolapse may cause no bother in one individual and a severe form of bother in another. The aim of this study was to determine the factors contributing to the degree of bother due to a given degree of prolapse, to help with the clinical evaluation of patients and planning of preventive intervention trials and surgical treatment.MethodsConsecutive patient records of 654 women who had attended a urogynecology unit between August 2011 and December 2012 were reviewed. All patients underwent a standardized interview, clinical examination and four‐dimensional translabial ultrasound scan. The degree of bother was evaluated using a visual analog scale.ResultsSix hundred and thirty‐six women were included in the analysis, with ultrasound data available for cystocele, rectocele and enterocele descent and rectocele depth measurements and 442 for uterine descent. 313 women (49.2%) had subjective symptoms of female pelvic organ prolapse at a mean bother score of 6.0 ± 2.6. Average bother score for the complete dataset was 3.0 ± 3.5. Parity, vaginal delivery, levator avulsion, any significant clinical prolapse or prolapse seen on ultrasound were associated with prolapse bother and all clinical and ultrasound measures of pelvic organ descent remained significant or near significant on multivariate analysis.ConclusionsQuantification of prolapse bother using a visual analog scale is valid and repeatable and may represent a simple tool for use in clinical practice.

ABSTRACTObjectiveTo determine associations between fetal lung and liver herniation volumes measured by magnetic resonance imaging (MRI) and mortality/need for extracorporeal membrane oxygenation (ECMO) in cases of isolated congenital diaphragmatic hernia (CDH). A secondary objective was to compare prenatal MRI parameters with two‐dimensional ultrasound lung measurements.MethodsA retrospective review of medical records of all fetuses with isolated CDH evaluated between January 2004 and July 2012 was performed. The following MRI parameters were measured at 20–32 weeks: observed/expected total fetal lung volume (o/e‐TLV), predicted pulmonary volume (PPV), percentage of liver herniated into the fetal thorax (%LH) and the liver/thoracic volume ratio (LiTR). These were compared with the ultrasound‐determined lung‐to‐head ratio (LHR) and the observed/expected LHR (o/e‐LHR) in the same cohort. The predictive value of MRI and ultrasound parameters for mortality and the need for ECMO was evaluated by univariate, multivariate and factor analysis and by receiver–operating characteristics curves.ResultsEighty fetuses with isolated CDH were evaluated. Overall mortality was 18/80 (22.5%). Two newborns died a few hours after birth. ECMO was performed in 29/78 (37.2%) newborns, with a survival rate of 48.3% (14/29). The side of the diaphragmatic defect was not associated with mortality (P = 0.99) or the need for ECMO (P = 0.48). Good correlation was observed among o/e‐TLV, PPV, LHR and o/e‐LHR as well as between %LH and LiTR (r = 0.89; P < 0.01); however, fetal lung measurements and measures of liver herniation were not correlated (all P > 0.05). All parameters were statistically associated with mortality or the need for ECMO. The best combination of measurements to predict mortality was o/e‐TLV and %LH, with 83% accuracy.ConclusionMortality and the need for ECMO in neonates with isolated CDH can be best predicted using a combination of MRI o/e‐TLV and %LH.

High spatial resolution vegetation mapping for assessment of wildlife habitat

Published: October 2013

ABSTRACTManagement of large herbivore populations requires assessment of both the quality and quantity of habitats available to the animals. Classifying and quantifying their habitats, particularly the availability of forage, is often challenging because of the time and expense associated with collection of the appropriate data over large landscapes. Land‐cover maps generated from remote‐sensing imagery generally provide only qualitative information regarding species composition of the vegetation, and do not adequately quantify forage species availability. Our objective was to determine the feasibility of mapping important forage species for moose (Alces americanus) in South‐central Alaska, USA, using fine‐resolution aerial photography. We used infrared and color digital photography acquired at an altitude of 150 m across 2 study areas with distinctly different vegetation to provide spectral data for supervised classifications of plant species using the maximum likelihood algorithm. We analyzed spring, autumn, and composite sets of the imagery to determine which imagery provides the most accurate classifications. Willow (Salix spp.) was separable from non‐forage species in autumn images with an average overall accuracy of 76% in the Nelchina study area and 78% in Placer Valley. The classifications of composite images separated important moose forages, but with lower average overall accuracies (68% for Nelchina study area and 75% for Placer Valley) compared with the autumn classifications. Spring classifications were least accurate (57% for Nelchina study area and 63% for Placer Valley), likely because the green‐up of plants in the spring occurred rapidly for all species in both study sites, and this resulted in relatively small differences in spectral response patterns between species. © 2013 The Wildlife Society. © The Wildlife Society, 2013
Testing the hypothesis of absence of unobserved confounding in semiparametric bivariate probit models

Published: October 2013

AbstractLagrange multiplier and Wald tests for the hypothesis of absence of unobserved confounding are extended to the context of semiparametric recursive and sample selection bivariate probit models. The finite sample size properties of the tests are examined through a Monte Carlo study using several scenarios: correct model specification, distributional and functional misspecification, with and without an exclusion restriction. The simulation results provide some guidelines which may be important for empirical analysis. The tests are illustrated using two datasets in which the issue of unobserved confounding arises.

AbstractAFP111 is a spontaneous mutant of Escherichia coli with mutations in the glucose-specific phosphotransferase system, pyruvate formate lyase system, and fermentative lactate dehydrogenase system, created to reduce byproduct formation and increase succinic acid accumulation. In AFP111, conversion of xylose to succinic acid only generates 1.67 ATP per xylose, but requires 2.67 ATP for xylose metabolism. Therefore, the ATP produced is not adequate to accomplish the conversion of xylose to succinic acid in chemically defined medium. An E. coli mutant was obtained by atmospheric and room-temperature plasmas and metabolic evolution strategies, which had the ability to use xylose and improve the capacity of cell growth. The concentration of ATP in the mutant was 1.33-fold higher than that in AFP111 during xylose fermentation. In addition, under anaerobic fermentation with almost 80 % xylose from corn stalk hydrolysate, a succinic acid concentration of 21.1 g l−1 was obtained, with a corresponding yield of 76 %.
