Abstract

BACKGROUND
The early diagnosis of urgent abdominal pain (UAP) is challenging. Most causes of UAP are associated with extensive inflammation. Therefore, we hypothesized that quantifying inflammation using interleukin-6 and/or procalcitonin would provide incremental value in the emergency diagnosis of UAP.

METHODS
This was an investigator-initiated prospective, multicenter diagnostic study enrolling patients presenting to the emergency department (ED) with acute abdominal pain. Clinical judgment of the treating physician regarding the presence of UAP was quantified using a visual analog scale after initial clinical and physician-directed laboratory assessment, and again after imaging. Two independent specialists adjudicated the final diagnosis and the classification as UAP (life-threatening, needing urgent surgery and/or hospitalization for acute medical reasons) using all information including histology and follow-up. Interleukin-6 and procalcitonin were measured blinded in a central laboratory.

RESULTS
UAP was adjudicated in 376 of 1038 (36%) patients. Diagnostic accuracy for UAP was higher for interleukin-6 [area under the ROC curve (AUC), 0.80; 95% CI, 0.77–0.82] vs procalcitonin (AUC, 0.65; 95% CI, 0.62–0.68) and clinical judgment (AUC, 0.69; 95% CI, 0.65–0.72; both P &lt; 0.001). Combined assessment of interleukin-6 and clinical judgment increased the AUC at presentation to 0.83 (95% CI, 0.80–0.85) and after imaging to 0.87 (95% CI, 0.84–0.89) and improved the correct identification of patients with and without UAP (net improvement in mean predicted probability: presentation, +19%; after imaging, +15%; P &lt; 0.001). Decision curve analysis documented incremental value across the full range of pretest probabilities. A clinical judgment/interleukin-6 algorithm ruled out UAP with a sensitivity of 97% and ruled in UAP with a specificity of 93%.

CONCLUSIONS
Interleukin-6 significantly improves the early diagnosis of UAP in the ED.

As cardiopatias representam importantes causas de internação e óbitos em crianças e o conhecimento de informações de âmbito epidemiológico são determinantes para tomada de decisão nos serviços de saúde. O objetivo do presente estudo é analisar o número de óbitos por causas evitáveis, desde o ano de 2007 até 2017, sobre anomalias congênitas do coração e circulatório em crianças menores de cinco anos no estado do Pará. A pesquisa é do tipo qualitativa, descritivo-exploratória. Foi realizada uma análise documental, contidos nas declarações de óbitos, levantados pelo Sistema de Informação sobre Mortalidade (SIM) e a busca na literatura para identificar a importância da assistência de enfermagem no cuidado de crianças menores de cinco com anomalias congênitas do coração e circulatório. O estado do Pará ocupa, no ranking, o primeiro lugar (44,94%) em relação à região norte, embora o índice seja considerado baixo se comparado aos outros estados e regiões. Nas crianças menores de cinco anos, as mortes devido a malformações estão entre as principais causas de óbito, atrás apenas das afecções perinatais. A importância da assistência de enfermagem no cuidado dessas crianças possui uma tarefa desgastante do ponto de vista emocional, mas capaz de gerar grande satisfação pessoal. Acredita-se ser de grande importância a realização de pesquisas de enfermagem com famílias que vivenciam tal situação, a fim de melhor compreender sua experiência no processo de cuidar da criança em seu cotidiano.

Das kooperative Identifizieren und Implementieren von Verbesserungsbedarf kann organisiert werden als moderierter, zeitweiliger Kleingruppenprozess. Die Teilnehmer tauschen dabei unterschiedliche Sichtweisen und Erfahrungen aus und erproben sie. Praktisches Problemlösen, Erfahrungsaustausch und Erfahrungserprobung sind Aspekte sozialen Lernens im Arbeitsprozess, die mit der Digitalisierung an Bedeutung gewinnen.
Äsopische geschichten in Meisterlied, Spruchgedicht und comedi
Authors: Holzberg Niklas 
Published: December 2018

Abstract
Hans Sachs, who, in upwards of 6000 poetic works, brought literature to the German-speaking urban middle and lower classes, adapted for his largely illiterate audience lengthy portions of Steinhöwel’s ›Esopus‹, including the ›Life of Aesop‹, turning them into Meisterlieder, Spruchgedichte, and a comedi. The ›Life‹ was the source, for one, of selected episodes which he could each rework adeptly for easy listening as individual shorter texts. In the work he wrote for the stage, ›Esopus der fabeldichter‹, moreover, he used his skill as dramatist to link a few episodes from the ›Life‹ and make of them a coherent plot with scenes not just strung loosely together, but united by an overarching theme.
Citation as Exchange Value
Authors: Aroch Fugellie Paulina 
Published: December 2018

Abstract
This article focuses on the interplay between correlated textual subject positions, insofar as they are differently legitimated across the New International Division of Labour (NIDL). In examining the academic system of referencing or invocation, I will pay particular attention to how it functions as a circuit of value production in the cultural domain. Marx’s theory of value production will be used as an exegetic tool to locate the workings of economic power in the referential apparatus of the contemporary academy, showing how Third-World symbolic production is undervalued despite its existence, since economic conditions retroactively foreclose the validation of Third-World intellectual and artistic production as cultural capital. As a case study, I will analyse some of the citation strategies of postcolonial theorist Anthony Appiah in In My Father’s House, which operates within the presupposition that textual subject positions (the place of enunciation in particular) are made available only to privileged subjects in the extra-textual world. Appiah’s methodology opens up what I call a circumscribed redistribution of cultural capital across the NIDL. Hence, I take In My Father’s House not only as an object of analysis but also as a critical source to understand how value production mediates academic writing, allowing Appiah’s conceptualization of the relationship between textual and social subjects to inform my own.
Output Effects of Global Food Commodity Shocks

Published: December 2018

AbstractThe dramatic fluctuations in global food prices over the past two decades have generated significant concern about their destabilizing macroeconomic effects. While the pass-through effects of international food prices on domestic prices have been widely documented, these estimates have not taken into account reverse causality, omitted variable bias, or differences in sources of international food price fluctuations. We use sign restrictions to identify relevant demand and supply shocks that explain the volatility in global food prices. We quantify their dynamic effects on several components of food exporters’ and food importers’ domestic output, including household consumption, government consumption, investment, and net exports. Our findings reveal that identifying the sources of the shocks driving global food prices is crucial to evaluating their domestic effects. Expansions in global economic activity that increase global food prices stimulate the domestic output of both food-importing and food-exporting economies; however, disruptions in global food commodity markets that lead to rising real food prices have large contractionary effects for food importers due to deteriorating trade balances and falling household consumption. We also document that the adverse effects of unfavorable global food shocks on household consumption are greater for food-importing countries with relatively high shares of household food expenditures and large food trade deficits.
Proposed Use of Monte Carlo Simulated Images to Evaluate the Accuracy of Measurements on X-Ray Computed Tomography

Published: December 2018

Abstract
X-ray computed tomography (CT) is increasingly recognized as a promising measuring technique for dimensional metrology. Various methods are being developed to improve measurement accuracy. Tests of new methods for such applications include accuracy evaluation with the use of calibrated workpieces; however, the internal algorithms of image acquisition and data processing might influence the experimental error, and then also the comparison of methods at different CTs. The accuracy of the results of tomographic measurements is influenced by many factors, one of which is the setting of the threshold value. The article presents the results of an attempt to use Monte Carlo simulated images to estimate deviations to determine threshold values to improve measurement accuracy and additionally, to estimate the impact of data processing. The differences of the results obtained from the simulated images were up to 4 % larger than those from tomographic images. It was caused by degradation of the image contrast by scattered radiation.

Abstract
Dynamic contrast enhanced MRI (DCE-MRI) and dynamic susceptibility contrast MRI (DSC-MRI) are perfusion imaging techniques used mainly for clinical and preclinical measurement of vessel permeability and capillary blood flow, respectively. It is advantageous to apply both methods to exploit their complementary information about the perfusion status of the tissue. We propose a novel acquisition method that combines advantages of the current simultaneous and sequential acquisition. The proposed method consists of a DCE-MRI acquisition interrupted by DSC-MRI acquisition. A new method for processing of the DCE-MRI data is proposed which takes the interleaved acquisition into account. Analysis of both the DCE- and DSC-MRI data is reformulated so that they are approximated by the same pharmacokinetic model (constrained distributed capillary adiabatic tissue homogeneity model). This provides a straightforward evaluation of the methodology as some of the estimated DCE- and DSC-MRI perfusion parameters should be identical. Evaluation on synthetic data showed an acceptable precision and no apparent bias introduced by the interleaved character of the DCE-MRI acquisition. Intravascular perfusion parameters obtained from clinical glioma data showed a fairly high correlation of blood flow estimates from DCE- and DSC-MRI, however, an unknown scaling factor was still present mainly because of the tissue-specific

relaxivity. The results show validity of the proposed acquisition method. They also indicate that simultaneous processing of both DCE- and DSC-MRI data with joint estimation of some perfusion parameters (included in both DCE- and DSC-MRI) might be possible to increase the reliability of the DCE- and DSC-MRI methods alone.
Hybrid photosensitive structures based on nematic liquid crystals and lithium niobate substrates
Authors: Lucchetti Liana , Reshetnyak Victor 
Published: December 2018

Abstract
Liquid crystal cells based on lithium niobate substrates have recently been proposed as good candidates for optofluidic devices and for light-induced controlled generation of defects in liquid crystal films. The peculiarity of these structures lies in the possibility of using the bulk photovoltaic effect of lithium niobate to obtain an optically induced dc field able to affect the molecular liquid crystal director. Reversible fragmentation and self-assembling of liquid crystal droplets driven by the lithium niobate pyroelectric properties have also been reported. We review the basic results obtained so far with the aim of making the point and seeing what else can be done in the framework of the realization of hybrid structures combining lithium niobate with the electro-optical and nonlinear optical properties of liquid crystals.
Super-structured photonic crystal fiber Bragg grating biosensor image model based on sparse matrix
Authors: Li Bo , Kanugo Jayanth 
Published: December 2018

Abstract
Fiber grating (FBG) is an important optical device of fiber, which is widely used in optical fiber communication and sensing. At the present stage, the fiber grating is almost prepared in the static state of the fiber, and then the grating is welded into the fiber grating array or network. With the continuous improvement of the application effect of fiber grating, has become one of the most promising, representative and fastest developing fiber passive devices. In this paper, fiber grating is classified according to the refractive index distribution of grating axis. The central wavelength of Bragg fiber grating is modulated by using external parameters (temperature or stress strain). The wave equation of insulating medium is obtained by the reflection characteristic and coupling mode theory of fiber grating. Using sparse matrix model of nerve action potential signal with wavelet decomposition layers, nerve action potential signal reconstruction of the relative error between the value and the original value contrast found that reconstructed and original signals are very close. Good results have been obtained for the sampling reconstruction of the filtered high signal-to-noise ratio neural action potential signal. Researchers have conducted extensive and in-depth research on fiber grating sensing technology, and achieved gratifying results. But with the of the engineering application of technical requirements, they need real-time monitoring. Due to the cross sensitivities of fiber grating, it became the bottleneck of multiple parameter measurement.
Application of modified culture Kalman filter in bearing fault diagnosis
Authors: Hailun Wang , Martinez Alexander 
Published: December 2018

Abstract
Rolling bearings are an important part of rotary machines. They are used most widely in various mechanical sectors, which are among the most vulnerable components in machines. This paper uses CKF algorithm to compile a signal analysis system, analyses the vibration signal of the rolling bearing, extracts fault features, and realizes fault diagnosis. In order to improve the estimation accuracy of bearing fault diagnosis under nonlinear model, a nonlinear model of bearing fault diagnosis based on quaternion and low-accuracy high-noise sensors is established, and the attitude estimation has performed using the culture Kalman filter (CKF) algorithm. The sensor data comparison shows that the use of the volumetric Kalman filter algorithm can effectively improve the estimation accuracy of bearing fault diagnosis and stability. In this paper, the measured vibration signals of several groups of rolling bearings are analysed, and the signal characteristic frequency has extracted. The results show that using the analysis software designed in this paper, several typical faults of rolling bearings can be correctly identified.

Examining the Role of Expressed Emotion in the Intergenerational Transmission of Mental Health Problems
Authors: Arroyo Analisa , Segrin Chris , Andersen Kristin K. 
Published: December 2018

Introduction: The aim of this study was to test a model of the intergenerational transmission of mental health problems (indicated by depression, anxiety, and loneliness) in which expressed emotion (indicated by criticism and emotional involvement) was specified as a mediator of mental health problems over multiple family generations. Method: The sample consisted of three generations of grandmothers, mothers, and daughters (N = 242 family triads), wherein participants completed online surveys in which they self-reported on their own mental health problems and perceptions of their mothers’ expressed emotion. Results: Results revealed only modest evidence of direct effects for the intergenerational transmission of mental health problems. However, there were a number of significant indirect effects, with all of these effects occurring through the criticism component of expressed emotion. Discussion: This research identified expressed emotion as both a risk factor for offspring's mental health problems as well as a behavior typical of parents with mental health problems. Specifically, the results revealed that mental health problems are intergenerationally transmitted via critical parent-child interactions.
Investigation of the Developmental Requirements of Drosophila HP1 and Insulator Protein Partner, HIPP1
Authors: Glenn Steve E , Geyer Pamela K 
Published: December 2018

Abstract
Drosophila Suppressor of Hairy-wing [Su(Hw)] is a multifunctional zinc finger DNA binding protein. Transcriptional regulation by Su(Hw) is essential in the ovary and testis, where Su(Hw) functions primarily as a repressor. Recently, the HP1a and Insulator Partner Protein 1 (HIPP1) was found to extensively co-localize with Su(Hw) and other insulator binding proteins in euchromatic regions of the genome, and with Heterochromatin Protein 1a (HP1a) in heterochromatic regions. As HIPP1 is the homolog of the human co-repressor Chromodomain Y-Like (CDYL), we tested its requirement in establishing transcriptional repression in flies. To this end, we generated multiple Hipp1 null alleles and a tagged derivative of the endogenous gene (Hipp1GFP), using CRISPR mutagenesis. We show that HIPP1 is a widely expressed nuclear protein that is dispensable for viability, as well as female and male fertility. We find that HIPP1 and HP1a display minimum co-localization in interphase cells, and HP1a-dependent transcriptional repression of several reporter genes is HIPP1-independent, indicating that HIPP1 is not essential for HP1a-dependent heterochromatin formation. Despite Su(Hw) having a major role in promoting HIPP1 occupancy in euchromatin, we show that HIPP1 is dispensable for the transcriptional and insulator functions of Su(Hw), indicating that HIPP1 is not a critical Su(Hw) cofactor. Further studies are needed to clarify the role of HIPP1 in Drosophila development.
Digitalisierung und unentgeltliche Angebote im Kartellrecht

Zusammenfassung
Die Entwicklung der Internetökonomie hat in den letzten Jahren erheblich an Dynamik gewonnen. Begleitet wurde diese Entwicklung von einer Vielzahl innovativer Geschäftsmodelle. Dazu gehört eine Reihe von Geschäftsmodellen, die mit kostenlosen Angeboten und Grenzkosten von nahezu null einhergehen. Obwohl dies kein völlig unbekanntes und neues Phänomen im Kartellrecht ist, haben die letzten Jahre gezeigt, dass die Verbreitung dieser Geschäftsmodelle durch die Internetwirtschaft deutlich zugenommen hat und die Modelle komplexer geworden sind. Der Artikel analysiert daher diese Geschäftsmodelle. Einige der Modelle sind dauerhaft und andere nur temporär. Herausragend in diesem Zusammenhang sind sicherlich die Entwicklung von Plattformmärkten und nicht monetärer Kompensationsmodelle, die auf einer Datenbereitstellung oder auf der Aufmerksamkeit der Nutzer beruhen. Wie die Analyse zeigt, stellten diese Null-Preis-Geschäftsmodelle die Kartellbehörden vor neue Herausforderungen, da umsatzbasierte Fusionsanmelde- oder Marktmachtschwellen und etablierte Methoden der Marktdefinition ihre Grenzen erreichen, wenn es um kostenlose Angebote geht. Die Analyse zeigt jedoch auch, dass sich Gesetzgeber und Wettbewerbsbehörden an diese Entwicklung angepasst haben und auf diese Geschäftsmodelle differenziert reagierten. Ein aktuelles Beispiel ist die 9. GWB-Novelle, durch die neue Schwellenwerte für die Fusionsanmeldungen auf Basis des Transaktionswerts in das deutsche Wettbewerbsrecht eingeführt wurden. In dem Artikel wird allerdings auch darauf hingewiesen, dass weitere Untersuchungen erforderlich sind, um das etablierte Repertoire an ökonomischen Methoden an diese neuen Geschäftsmodelle anzupassen.
