Authors: Borgman Christine L. , Van de Sompel Herbert , Scharnhorst Andrea , van den Berg Henk , Treloar Andrew 
Published: February 2016

ABSTRACTDespite the advances in policy and practice for data sharing, surprisingly little is known about the uses and users of digital data archives, about relationships between users and the staff of data archives, or how these behaviors vary by discipline, geographic region, policy, and other factors. Digital data archives are not a single type of institution, however. They vary widely in organizational structure, mission, collection, funding, and relationships to their users and other stakeholders. We present an exploratory study of DANS, the Digital Archiving and Networked Services of the Netherlands, with the goal of identifying methods for studying the contributors, consumers, and role of archivists in digital data archives. Starting with transaction logs that serve management purposes, we present estimates of the distribution of uses and users of DANS. Units of analysis necessary to study user behavior, such as dataset, file, user, creator, and consumer, are difficult to glean from logs that were not designed for these inquiries. We recommend methods for improving the design of data collection instruments and outline the subsequent phases of our mixed‐method research on the uses, users, policy, and practice of digital data archiving.
How does citing behavior for a scientific article change over time? A preliminary study
Authors: LU Ch'ao , ZHANG Chengzhi , MA Shutian 
Published: February 2016

ABSTRACTThis study is to investigate how citing behavior for a scientific article changes over time. A highly cited article is chosen to collect citation content from its 902 citing articles. Natural language processing and content analysis are adopted to encode citation content and complete the statistics of citation behavior. Citation content analysis indexes including citation mention, length, and location, are used to describe the changes of citation behavior over time. The experimental results show that there is correlation between citing time with most of the indexes and that citation mention and citation length are declining while the number of the citation co‐occurrences is increasing.

Authors: Dahlmann Rainer , Hopmann Christian , Jaritz Montgomery , Kirchheim Dennis 
Published: February 2016

AbstractInsbesondere die optische Transparenz und die hervorragende Sperrwirkung siliziumoxidischer Beschichtungen gegenüber Gasen und Aromen sichern den PECVD‐Schichten in der Barriereausrüstung von Kunststoffen ihre Bedeutung. Während für Kunststoffe die Transportvorgänge von Gasen und Aromen durch das Arrhenius‐Modell als Permeation durch einen Festkörper beschrieben werden kann, sind für die PECVD‐Schichten und insbesondere mehrschichtige Verbunde aus PECVD‐Schichten nur wenige Modelle in der Literatur beschrieben. Es existieren Modelle, die auf der Diffusion durch Defekte innerhalb der PECVD‐Beschichtungen basieren und annehmen, dass außerhalb der Defekte keine Permeation stattfindet. Gegenstand der Forschung ist die Überprüfung der Gültigkeit der verschiedenen Modelle vor dem Hintergrund experimenteller Daten zu Sauerstoff‐ und Wasserdampftransmission. Um die Gültigkeit der verschiedenen Modelle abzuleiten, werden ein‐ und beidseitige Beschichtungen aus variierenden Schichtarchitekturen miteinander verglichen.

Floods are the most frequent of natural disasters, affecting millions of people across the globe every year. The anticipation and forecasting of floods at the global scale is crucial to preparing for severe events and providing early awareness where local flood models and warning services may not exist. As numerical weather prediction models continue to improve, operational centers are increasingly using their meteorological output to drive hydrological models, creating hydrometeorological systems capable of forecasting river flow and flood events at much longer lead times than has previously been possible. Furthermore, developments in, for example, modelling capabilities, data, and resources in recent years have made it possible to produce global scale flood forecasting systems. In this paper, the current state of operational large‐scale flood forecasting is discussed, including probabilistic forecasting of floods using ensemble prediction systems. Six state‐of‐the‐art operational large‐scale flood forecasting systems are reviewed, describing similarities and differences in their approaches to forecasting floods at the global and continental scale. Operational systems currently have the capability to produce coarse‐scale discharge forecasts in the medium‐range and disseminate forecasts and, in some cases, early warning products in real time across the globe, in support of national forecasting capabilities. With improvements in seasonal weather forecasting, future advances may include more seamless hydrological forecasting at the global scale alongside a move towards multi‐model forecasts and grand ensemble techniques, responding to the requirement of developing multi‐hazard early warning systems for disaster risk reduction.

A survey on Neyman‐Pearson classification and suggestions for future research
Authors: Tong Xin , Feng Yang , Zhao Anqi 
Published: February 2016

In statistics and machine learning, classification studies how to automatically learn to make good qualitative predictions (i.e., assign class labels) based on past observations. Examples of classification problems include email spam filtering, fraud detection, market segmentation. Binary classification, in which the potential class label is binary, has arguably the most widely used machine learning applications. Most existing binary classification methods target on the minimization of the overall classification risk and may fail to serve some real‐world applications such as cancer diagnosis, where users are more concerned with the risk of misclassifying one specific class than the other. Neyman‐Pearson (NP) paradigm was introduced in this context as a novel statistical framework for handling asymmetric type I/II error priorities. It seeks classifiers with a minimal type II error subject to a type I error constraint under some user‐specified level. Though NP classification has the potential to be an important subfield in the classification literature, it has not received much attention in the statistics and machine learning communities. This article is a survey on the current status of the NP classification literature. To stimulate readers' research interests, the authors also envision a few possible directions for future research in NP paradigm and its applications.

Spatial modeling with system of stochastic partial differential equations
Authors: Hu Xiangping , Steinsland Ingelin 
Published: February 2016

To define a spatial process as the solution to a stochastic partial differential equation (SPDE) is an approach to spatial modeling that is gaining popularity. The model corresponds to a Gaussian random spatial process with Matérn covariance function. The SPDE approach allows for computational benefits and provides a framework for making valid complex models (e.g., nonstationary spatial models). Using systems of SPDEs to define spatial processes extends the class of models that can be specified as SPDEs, while the computational benefits are kept. In this study, we give an overview of the current state of spatial modeling with systems of SPDEs. Systems of SPDEs have contributed toward modeling and computational efficient inference for spatial Gaussian random field (GRF) models with oscillating covariance functions and multivariate GRF models. For multivariate GRF models special systems of SPDEs corresponding to models known from the literature are set up. Little work has been done for exploring opportunities and properties of spatial processes defined as systems of SPDEs. We also describe some of the interesting topics for further research.

The impact of heterologous catalase expression and superoxide dismutase overexpression on enhancing the oxidative resistance in Lactobacillus casei
Authors: Lin Jinzhong , Zou Yexia , Cao Kunlin , Ma Chengjie , Chen Zhengjun 
Published: February 2016

Abstract
Two heme-dependent catalase genes were amplified from genomic DNA of Lactobacillus plantarum WCFS1 (KatE1) and Lactobacillus brevis ATCC 367 (KatE2), respectively, and a manganese-containing superoxide dismutase from Lactobacillus casei MCJΔ1 (MnSOD) were cloned into plasmid pELX1, yielding pELX1-KatE1, pELX1-KatE2 and pELX1-MnSOD, then the recombinant plasmids were transferred into L. casei MCJΔ1. The strains of L. casei MCJΔ1/pELX1-KatE1 and L. casei MCJΔ1/pELX1-KatE2 were tolerant at 2 mM H2O2. The survival rates of L. casei MCJΔ1/pELX1-KatE1 and L. casei MCJΔ1/pELX1-KatE2 were 270-fold and 300-fold higher than that of the control strain on a short-term H2O2 exposure, and in aerated condition, the survival cells counts were 146- and 190-fold higher than that of the control strain after 96 h of incubation. Furthermore, L. casei MCJΔ1/pELX1-MnSOD was the best in three recombinants which was superior in the living cell viability during storage when co-storage with Lactobacillus delbrueckii subsp. lactis LBCH-1.
A newt does not change its spots: using pattern mapping for the identification of individuals in large populations of newt species
Authors: Mettouris Onoufrios , Megremis George , Giokas Sinos 
Published: February 2016

AbstractThe correct identification of individuals is a requirement of capture‐mark‐recapture (CMR) methods, and it is commonly achieved by applying artificial marks or by mutilation of study‐animals. An alternative, non‐invasive method to identify individuals is to utilize the patterns of their natural body markings. However, the use of pattern mapping is not yet widespread, mainly because it is considered time consuming, particularly in large populations and/or long‐term CMR studies. Here we explore the use of pattern mapping for the identification of adult individuals in the alpine (Ichthyosaura alpestris) and smooth (Lissotriton vulgaris) newts (Amphibia, Salamandridae), using the freely available, open‐source software Wild‐ID. Our photographic datasets comprised nearly 4000 captured animals’ images, taken during a 3‐year period. The spot patterns of individual newts of both species did not change through time, and were sufficiently varied to allow their individual identification, even in the larger datasets. The pattern‐recognition algorithm of Wild‐ID was highly successful in identifying individual newts in both species. Our findings indicate that pattern mapping can be successfully employed for the identification of individuals in large populations of a broad range of animals that exhibit natural markings. The significance of pattern‐mapping is accentuated in CMR studies that aim in obtaining long‐term information on the demography and population dynamics of species of conservation interest, such as many amphibians facing population declines.

Abstract
Lung cancer causes more deaths in men and women than any other cancer related disease. Currently, few effective strategies exist to predict how patients will respond to treatment. We evaluated the serum metabolomic profiles of 25 lung cancer patients undergoing chemotherapy ± radiation to evaluate the feasibility of metabolites as temporal biomarkers of clinical outcomes. Serial serum specimens collected prospectively from lung cancer patients were analyzed using both nuclear magnetic resonance (1H-NMR) spectroscopy and gas chromatography mass spectrometry (GC–MS). Multivariate statistical analysis consisted of unsupervised principal component analysis or orthogonal partial least squares discriminant analysis with significance assessed using a cross-validated ANOVA. The metabolite profiles were reflective of the temporal distinction between patient samples before during and after receiving therapy (1H-NMR, p < 0.001: and GC–MS p < 0.01). Disease progression and survival were strongly correlative with the GC–MS metabolite data whereas stage and cancer type were associated with 1H-NMR data. Metabolites such as hydroxylamine, tridecan-1-ol, octadecan-1-ol, were indicative of survival (GC–MS p < 0.05) and metabolites such as tagatose, hydroxylamine, glucopyranose, and threonine that were reflective of progression (GC–MS p < 0.05). Metabolite profiles have the potential to act as prognostic markers of clinical outcomes for lung cancer patients. Serial 1H-NMR measurements appear to detect metabolites diagnostic of tumor pathology, while GC–MS provided data better related to prognostic clinical outcomes, possibility due to physiochemical bias related to specific biochemical pathways. These results warrant further study in a larger cohort and with various treatment options.

Published: February 2016

AbstractArkansas‐grown non‐genetically modified soybean cultivar, R08‐4004, was selected to prepare a protein isolate, which was treated with Alcalase for limited enzymatic hydrolysis. The objective was to optimize the Alcalase hydrolysis condition to produce soy protein hydrolysate (SPH) with high protein yield, low bitterness, and clarity for beverage applications. The degree of hydrolysis ranged between 14 and 52 % during the study at varying incubation times using two different concentrations of Alcalase enzyme. Recovery of soluble protein, between 21 and 53 %, was achieved with a decrease in turbidity. There was an increase in surface hydrophobicity (S0) which is correlated with bitterness of SPH treated with 1.0 AU (3.2 µL/g) of Alcalase 2.4 L. The sodium dodecyl sulfate‐polyacrylamide gel electrophoresis analysis showed a distinct hydrolysis pattern in which 7S globulin and the two acidic sub‐units of 11S globulin were hydrolyzed extensively in comparison to the two basic sub‐units of 11S globulin. Limited enzymatic hydrolysis produced low molecular weight peptides <17 kDa. Among these SPHs, the one derived after 120 min incubation had the highest soluble protein yield (43 %), low S0 value (35.4), low turbidity (0.88), and highest angiotensin‐I converting enzyme (ACE‐I) inhibition activity (66.6 %). This hydrolysate has potential use as protein rich nutraceutical for developing many non‐genetically modified food product applications.

AbstractBackgroundDeficits of mismatch negativity (MMN) in schizophrenia and individuals at risk for psychosis have been replicated many times. Several studies have also demonstrated the occurrence of subclinical psychotic symptoms within the general population. However, none has yet investigated MMN in individuals from the general population who report subclinical psychotic symptoms.MethodsThe MMN to duration-, frequency-, and intensity deviants was recorded in 217 nonclinical individuals classified into a control group (n = 72) and three subclinical groups: paranoid (n = 44), psychotic (n = 51), and mixed paranoid-psychotic (n = 50). Amplitudes of MMN at frontocentral electrodes were referenced to average. Based on a three-source model of MMN generation, we conducted an MMN source analysis and compared the amplitudes of surface electrodes and sources among groups.ResultsWe found no significant differences in MMN amplitudes of surface electrodes. However, significant differences in MMN generation among the four groups were revealed at the frontal source for duration-deviant stimuli (P = 0.01). We also detected a trend-level difference (P = 0.05) in MMN activity among those groups for frequency deviants at the frontal source.ConclusionsIndividuals from the general population who report psychotic symptoms are a heterogeneous group. However, alterations exist in their frontal MMN activity. This increased activity might be an indicator of more sensitive perception regarding changes in the environment for individuals with subclinical psychotic symptoms.

AbstractBackgroundAlthough there is a recommendation that toddlers be screened for Autism spectrum disorder (ASD) during their 18- and 24-month well-care child visits, diagnosis often occurs well after the child turns 4 years old. Such delayed diagnosis hinders the implementation of early intervention thus worsens the long-term prognosis of ASD.ObjectivesThe current community-based study in its stage I aimed at early screening of Egyptian toddlers for ASD using an Arabic validated version of Modified Checklist for Autism in Toddlers (M-CHAT).MethodologyA cross-sectional community-based descriptive study was carried out enrolling 5546 Egyptian toddlers. They were randomly recruited from those attending Primary Health Care Units in six Egyptian governorates with a fair representation of the urban, semi-urban, and rural Egyptian populations. An Arabic validated version of M-CHAT was used as a screening tool for ASD.ResultsThe current study revealed failure of M-CHAT (suspected to have ASD and needs further evaluation) in 1320 out of the enrolled 5546 Egyptian toddlers (23.8%).ConclusionsM-CHAT as a screening tool for ASD has flagged a considerable percent of the enrolled toddlers that necessitates referral for further evaluation (stage II) to settle the diagnosis of ASD in the true positive cases. Perfecting the delicate balance between sensitivity and specificity for ASD screening tools is crucial in order not to miss early detection of ASD cases and at the same time, to avoid over-diagnosis with subsequent abuse of the limited healthcare resources in developing countries.
