Published: June 2016

AbstractIm Gemengesilo eines Glaswerks kann es aufgrund von Zeitverfestigung zu Anbackungen von Material kommen. Diese meist im Wand‐ und Austragsbereich auftretenden Verfestigungen beeinträchtigen die Fließfähigkeit des Gemenges und die Produktqualität. Begünstigt wird die Bildung von Anbackungen insbesondere durch den Einsatz von Soda bei gleichzeitig hohem Feuchtegehalt. Der Einfluss des Mischprozesses auf die Zeitverfestigung eines Standardgemenges für Behälterglas wurde mit Scherversuchen untersucht.

SummarySecuring user identity from data breach in a web server is one of the major concerns for the users of the web applications. Similarly, protecting user access pattern from unauthorized access should be taken seriously, because the potential threats such attacks may pose, are huge. However, these security measures should not be adopted at the expense of user experience and convenience. Nevertheless, any extra overhead in the form of security measures introduced in a distributed system results in significant performance declination. The target of a secured framework for a distributed system like web application should be a reasonable trade‐off between security and user experience. Thus, in this work, we present a framework that ensures security for the user identity along with keeping the online activities of the users anonymous while ensuring scalability of the system. Our framework is designed in a scalable form that can work with other distributed architectures that provide security to user data and identities. To ensure all these measures, our proposal includes the implementation of Forward Secrecy using Diffie‐Hellman Key exchange protocol where the server cannot remember a user's history after a session ends. In addition, we present our own mechanism to hide logical data sharing strategies to protect users against selective DoS attacks. Moreover, we implemented a modified version of bloom filter to safeguard user access pattern in a compromised server. Our proposed implementation of bloom filter also ensures that the scalability of distributed system is preserved even with little infrequent overhead in the server because of security measures proposed in this work. Finally, we implemented different modules of our framework using both Web Socket and Long Polling transport protocols and recorded the time required to perform various tasks. Web socket protocol took less time to perform each task than the long polling protocol, which is convincing enough to suggest that web socket performs better than long polling in the given scenarios.

AbstractOBJECTIVEFetal cortisol may be reflected in hair collected shortly after birth. The objective of this study was to determine the range of human fetal hair cortisol concentrations (HCC) in live‐born neonates using an approach for processing small quantities of hair.MATERIALS AND METHODSHair was cut on the day of birth from neonates and their mothers, born between 26 and 42 weeks gestational age (GA). HCC was determined by enzyme immunoassay. Maternal sociodemographics and birth data were collected. T‐tests, ANOVA, Pearson correlation, and Wilcoxon Signed Rank test were used as appropriate.RESULTSNinety maternal and neonatal hair samples were cut from 79 term (T) and 11 preterm (PT) delivered pregnancies. All samples weighed ≥2.5 mg. Fetal HCC correlated with GA (r = .25, p = .02) and birth weight (r = .25, p = .03) and was lower in PT (4.3 ± .3 LN pg/mg) than T (5.3 ± .1, LN pg/mg, p < .001) neonates. No significant relationships were seen between fetal HCC and maternal characteristics or maternal HCC. Fetal HCC was significantly higher than maternal HCC.CONCLUSIONFetal cortisol exposure was determined using this approach for processing small amounts of hair. Preterm neonates have significantly lower HCC than term neonates and fetal HCC is associated with GA at delivery and birth weight. Fetal HCC is significantly higher than maternal HCC cut on the same day. These data provide novel information on the intrauterine fetal cortisol environment.
Fate mapping of Trps1 daughter cells during cardiac development using novel Trps1‐Cre mice

Published: June 2016

SummaryTricho‐rhino‐phalangeal syndrome (TRPS) is a rare congenital disorder that is characterized by abnormal hair growth and skeletal deformities. These result in sparse hair, short stature, and early onset of joint problems. Recent reports have shown that a relatively high proportion of patients with TRPS exhibit a broad range of congenital heart defects. To determine the regulation of Trps1 transcription in vivo, we generated novel transgenic mice, which expressed Cre recombinase under the murine Trps1 proximal promoter sequence (Trps1‐Cre). We crossed these mice with Cre reporter mice to identify Trps1 daughter cells. Labeled cells were observed in the appendicular joint tissue, dermal papilla of the hair follicles, cardiac valves, aortic sinus, atrial walls, and the interventricular septum. In situ analysis showed restricted Trps1 expression, which was observed in endocardial cushions of the outflow tract, and in leaflets of all mature cardiac valves. These results suggest that the Trps1 proximal promoter sequence contains some of the tissue‐specific Trps1 regulatory region. Further, our findings partially explain why patients with TRPS show a broad range of congenital cardiac defects, although Trps1 expression is observed in a more restricted fashion. genesis 54:379–388, 2016. © 2016 Wiley Periodicals, Inc.
Impaired inference in a case of developmental amnesia
Authors: D'Angelo Maria C. , Rosenbaum R. Shayna , Ryan Jennifer D. 
Published: June 2016

ABSTRACTAmnesia is associated with impairments in relational memory, which is critically supported by the hippocampus. By adapting the transitivity paradigm, we previously showed that age‐related impairments in inference were mitigated when judgments could be predicated on known pairwise relations, however, such advantages were not observed in the adult‐onset amnesic case D.A. Here, we replicate and extend this finding in a developmental amnesic case (N.C.), who also shows impaired relational learning and transitive expression. Unlike D.A., N.C.'s damage affected the extended hippocampal system and diencephalic structures, and does not extend to neocortical areas that are affected in D.A. Critically, despite their differences in etiology and affected structures, N.C. and D.A. perform similarly on the task. N.C. showed intact pairwise knowledge, suggesting that he is able to use existing semantic information, but this semantic knowledge was insufficient to support transitive expression. The present results suggest a critical role for regions connected to the hippocampus and/or medial prefrontal cortex in inference beyond learning of pairwise relations. © 2016 The Authors Hippocampus Published by Wiley Periodicals, Inc.

AbstractPeripheral T‐cell lymphomas (PTCLs) comprise a heterogeneous group of neoplasms that are derived from post‐thymic lymphoid cells at different stages of differentiation with different morphological patterns, phenotypes and clinical presentations. PTCLs are highly diverse, reflecting the diverse cells from which they can originate and are currently sub‐classified using World Health Organization (WHO) 2008 criteria. In 2006 the International T‐Cell Lymphoma Project launched the T‐Cell Project, building on the retrospective study previously carried on by the network, with the aim to prospectively collect accurate data to improve knowledge on this group of lymphomas. Based on previously published reports from International Study Groups it emerged that rendering a correct classification of PTCLs is quite difficult because the relatively low prevalence of these diseases results in a lack of confidence by most pathologists. This is the reason why the T‐Cell Project requested the availability of diagnostic material from the initial biopsy of each patient registered in the study in order to have the initial diagnosis centrally reviewed by expert hematopathologists. In the present report the results of the review process performed on 573 cases are presented. Overall, an incorrect diagnosis was centrally recorded in 13.1% cases, including 8.5% cases centrally reclassified with a subtype eligible for the project and 4.6% cases misclassified and found to be disorders other than T‐cell lymphomas; 2.1% cases were centrally classified as T‐Cell disorders not included in the study population. Thus, the T‐Cell Project confirmed the difficulties in providing an accurate classification when a diagnosis of PTCLs is suspected, singled out the major pitfalls that can bias a correct histologic categorization and confirmed that a centralized expert review with the application of adequate diagnostic algorithms is mandatory when dealing with these tumours.

Climate change analysis on historical watershed‐scale precipitation by means of long‐term dynamical downscaling
Authors: Ishida K. , Kavvas M. L. 
Published: June 2016

AbstractA methodology based on long‐term dynamical downscaling to analyse climate change effects on watershed‐scale precipitation during a historical period is proposed in this study. The reliability and applicability of the methodology were investigated based on the long‐term dynamical downscaling results. For an application of the proposed methodology, two study watersheds in Northern California were selected: the Upper Feather River watershed and the Yuba River watershed. Then, precipitation was reconstructed at 3‐km spatial resolution and hourly intervals over the study watersheds for 141 water years from 1 October 1871 to 30 September 2012 by dynamically downscaling a long‐term atmospheric reanalysis dataset, 20th century global reanalysis version 2 by means of a regional climate model. The reconstructed precipitation was compared against observed precipitation, in order to assess the applicability of the proposed methodology for the reconstruction of watershed‐scale precipitation and to validate this methodology. The validation shows that the reconstructed precipitation is in good agreement with observation data. Moreover, the differences between the reconstructed precipitation and the corresponding observations do not significantly change through the historical period. After the validation, climate change analysis was conducted based on the reconstructed precipitation. Through this analysis, it was found that basin‐average precipitation has increased significantly over both of the study watersheds during the historical period. An upward trend in monthly basin‐average precipitation is not significant in wet months except February while it is significant in dry months of the year. Furthermore, peak values of basin‐average precipitation are also on an upward trend over the study watersheds. The upward trend in peak basin‐average precipitation is more significant during a shorter duration. Copyright © 2016 John Wiley & Sons, Ltd.
Double funnelling in a mature coastal British Columbia forest: spatial patterns of stemflow after infiltration
Authors: Spencer S. A. , van Meerveld H. J. 
Published: June 2016

AbstractMany studies have focused on the amount of stemflow in different forests and for different rainfall events, but few studies have focused on how stemflow intensity varies during events or the infiltration of stemflow into the soil. Stemflow may lead to higher water delivery rates at the base of the tree compared with throughfall over the same area and fast and deeper infiltration of this water along roots and other preferential flow pathways. In this study, stemflow amounts and intensities were measured and blue dye experiments were conducted in a mature coniferous forest in coastal British Columbia to examine double funnelling of stemflow. Stemflow accounted for only 1% of precipitation and increased linearly with event total precipitation. Funnelling ratios ranged from less than 1 to almost 20; smaller trees had larger funnelling ratios. Stemflow intensity generally was highest for periods with high‐intensity rainfall later in the event. The maximum stemflow intensities were higher than the maximum precipitation intensities. Dye tracer experiments showed that stemflow infiltrated primarily along roots and was found more frequently at depth than near the soil surface. Lateral flow of stemflow was observed above a dense clay layer for both the throughfall and stemflow experiments. Stemflow appeared to infiltrate deeper (122 cm) than throughfall (85 cm), but this difference was in part a result of site‐specific differences in maximum soil depth. However, the observed high stemflow intensities combined with preferential flow of stemflow may lead to enhanced subsurface stormflow. This suggests that even though stemflow is only a very minor component of the water balance, it may still significantly affect soil moisture, recharge, and runoff generation.

Real‐time automated clinical deterioration alerts predict thirty‐day hospital readmission
Authors: Micek Scott T. , Samant Maanasi , Bailey Thomas , Chen Yixin , Lu Chenyang , Heard Kevin , Kollef Marin H. 
Published: June 2016

INTRODUCTIONClinical deterioration alerts (CDAs) are increasingly employed to identify deteriorating patients.METHODSWe performed a retrospective study to determine whether CDAs predict 30‐day readmission. Patients admitted to 8 general medicine units were assessed for all‐cause 30‐day readmission.RESULTSAmong 3015 patients, 567 (18.8%) were readmitted within 30 days. Patients triggering a CDA (n = 1141; 34.4%) were more likely to have a 30‐day readmission (23.6% vs 15.9%; P < 0.001). Logistic regression identified triggering of a CDA to be independently associated with 30‐day readmission (odds ratio [OR]: 1.40; 95% confidence interval [CI]: 1.26‐1.55; P = 0.001). Other predictors were: an emergency department visit in the previous 6 months (OR: 1.23; 95% CI:, 1.20‐1.26; P < 0.001), increasing age (OR: 1.01; 95% CI: 1.01‐1.02; P = 0.003), presence of connective tissue disease (OR: 1.63; 95% CI: 1.34‐1.98; P = 0.012), diabetes mellitus with end‐organ complications (OR: 1.23; 95% CI: 1.13‐1.33; P = 0.010), chronic renal disease (OR: 1.16; 95% CI: 1.08‐1.24; P = 0.034), cirrhosis (OR: 1.25; 95% CI: 1.17‐1.33; P < 0.001), and metastatic cancer (OR: 1.12; 95% CI: 1.08‐1.17; P = 0.002). Addition of the CDA to the other predictors added only modest incremental value for the prediction of hospital readmission.CONCLUSIONSReadily identifiable clinical variables can be identified that predict 30‐day readmission. It may be important to include these variables in existing prediction tools if pay for performance and across‐institution comparisons are to be “fair” to institutions that care for more seriously ill patients.

Arthritis, comorbidities, and care utilization in veterans of operations enduring and Iraqi Freedom
Authors: Rivera Jessica C. , Amuan Megan E. , Morris Ruth M. , Johnson Anthony E. , Pugh Mary Jo 
Published: June 2016

ABSTRACTVeteran populations are known to have frequencies of arthritis higher than civilian populations. The aim of this study is to define the prevalence of arthritis among a cohort of veterans from ongoing U.S. military operations. A retrospective cohort study using Veterans Administration data sources for service connected disability, comorbidities, clinic utilization, and pharmacy utilization was conducted including veterans who deployed in service to operations in Afghanistan or Iraq, comparing veterans with a diagnosis of arthritis, arthritis plus back pain, and veterans with no pain diagnoses. The frequency of arthritis was 11.8%. Veterans with arthritis and arthritis plus back pain had greater frequencies of diabetes, hyperlipidemia, hypertension, and obesity compare to veterans with no pain diagnosis. Veterans with arthritis plus back pain had the highest pain clinic utilization and prescription use of opioids and anti‐inflammatories. Veterans with no pain diagnosis had higher frequencies of diagnosis and clinic utilization for mental health disorders. Arthritis is prevalent among the latest generation of combat veterans and is associated with diabetes, obesity, and cardiovascular comorbidities. The need for arthritis care and associated comorbidities is expected to increase as the Veterans Administration and the civilian health care sector assumes care of these veterans. © 2016 Orthopaedic Research Society.

Abundance of sulfur‐degrading bacteria in a benthic bacterial community of shallow sea sediment in the off‐Terengganu coast of the South China Sea

Published: June 2016

AbstractThis study for the first time provides insight into the bacterial community in the benthic region of the Off‐Terengganu Coastline, which is considered to be anthropogenically polluted due to heavy fishing vessel commotion. Subsurface bacteria were randomly collected from two locations at different depths and were examined using the 16S rDNA V3‐V4 marker gene on the Illumina™ Miseq platform. In addition, the physiochemical parameters of the sediment were also measured. Surprisingly, the results show a high diversity of sulfur‐oxidizing bacteria in the surveyed area, where Sulfurovum sp. was identified to predominate the overall bacterial community. The physiochemical parameters reveal insufficient evidence of hydrothermal vents in the surveyed area. However, there are traces of hydrocarbon pollutants such as gasoline, diesel, and mineral oil in this area. It is assumed that sediment accumulation in the lee of breakwater plays an important role in trapping the runoff from the nearby harbor, which includes oil spills. Based on the common knowledge, Sulvurofum sp. is a native bacterium that exists in deep hydrothermal vents and volcanic territories. Although the reason for the abundance of Sulfurovum sp. in the surveyed area is still unclear, there is a possibility that metabolic adaptation plays an important role in regulating hydrocarbon pollutants for survival. The work presented in this paper therefore has profound implications for future studies on Sulfurovum sp. versatility. However, future research is needed to strengthen the findings of this study and to provide a better evidence regarding the metabolic response of this bacterium toward hydrocarbon pollutants.
Numerical evaluation of three non‐coaxial kinematic models using the distinct element method for elliptical granular materials
Authors: Jiang M. J. , Liu J. D. , Arroyo M. 
Published: June 2016

SummaryThis paper presents a numerical evaluation of three non‐coaxial kinematic models by performing Distinct Element Method (DEM) simple shear tests on specimens composed of elliptical particles with different aspect ratios of 1.4 and 1.7. The models evaluated are the double‐shearing model, the double‐sliding free‐rotating model and the double slip and rotation rate model (DSR2 model). Two modes of monotonic and cyclic simple shear tests were simulated to evaluate the role played by the inherent anisotropy of the specimens. The main findings are supported by all the DEM simple shear tests, irrespective of particle shape, specimen density or shear mode. The evaluation demonstrates that the assumption in the double‐shearing model is inconsistent with the DEM results and that the energy dissipation requirements in the double‐sliding free‐rotating model appear to be too restrictive to describe the kinematic flow of elliptical particle systems. In contrast, the predictions made by the DSR2 model agree reasonably well with the DEM data, which demonstrates that the DSR2 model can effectively predict the non‐coaxial kinematic behavior of elliptical particle systems.

Applicability of the International Affective Picture System in Chinese older adults: A validation study
Authors: Gong Xianmin , Wang Dahua 
Published: June 2016

AbstractThe International Affective Picture System (IAPS) is a standardized tool widely used to induce emotions in psychological studies. The present study examined the reliability and validity of theIAPSin Chinese older adults. A sample consisting of 126 Chinese older adults (86 females; aged 67.3 ± 4.96 years; 13.2 ± 2.75 years of education) was recruited to rate valence and arousal for 942IAPSpictures. The results showed a satisfactory reliability and validity of theIAPSamong these participants. The reliability was supported by high internal consistency and low inter‐individual variance of participants' ratings; the validity was supported by high similarities (in rating scores and in the distribution of the pictures in the valence–arousal affective space) and small differences (in mean ratings) between Chinese and German older adults. In conclusion, the study adds supportive evidence to the cross‐cultural validity of theIAPSin older adults, and provides a set of normative emotional ratings that could be adopted as a criterion in the selection of emotional pictures in future studies engaging Chinese older adults. Comparison of theIAPSratings across cultures and ages is also discussed.
Lithalsa Formation and Holocene Lake‐Level Recession, Great Slave Lowland, Northwest Territories
Authors: Wolfe S. A. , Morse P. D. 
Published: June 2016

AbstractLithalsas (ice‐cored permafrost mounds) are common within silty clay sediments of the Great Slave Lowland, a low‐relief bedrock plain extending to about 50 m above Great Slave Lake, Northwest Territories. Following retreat of the Laurentide Ice Sheet, sediment deposition in the lowland accompanied inundation by glacial Lake McConnell between about 12 700 and 9300 cal BP, and continued subsequently in ancestral Great Slave Lake. Lake‐level recession has occurred locally at about 5 mm · a−1 for the last 8000 years, due primarily to isostatic rebound. Maximum limiting ages of permafrost and lithalsas in the lowland are elevation‐dependent, being least near the modern shoreline and greater at higher elevations. Many lithalsas, which are up to 8 m high and several hundred metres wide, are less than 3000 years old. They are abundant in alluvium of the Yellowknife River deposited within the last 2000 years, with permafrost aggradation and lithalsa formation continuing in historical time.
