Development of hydrophobic paper substrates using silane and sol–gel based processes and deriving the best coating technique using machine learning strategies
Authors: Manoharan Kapil , Anwar Mohd. Tahir , Bhattacharya Shantanu 
Published: May 2021

AbstractLow energy surface coatings have found wide range of applications for generating hydrophobic and superhydrophobic surfaces. Most of the studies have been related to use of a single coating material over a single substrate or using a single technique. The degree of hydrophobicity is highly dependent on fabrication processes as well as materials being coated and as such warrants a high-level study using experimental optimization leading to the evaluation of the parametric behavior of coatings and their application techniques. Also, a single platform or system which can predict the required set of parameters for generating hydrophobic surface of required nature for given substrate is of requirement. This work applies the powerful machine learning algorithms (Levenberg Marquardt using Gauss Newton and Gradient methods) to evaluate the various processes affecting the anti-wetting behavior of coated printable paper substrates with the capability to predict the most optimized method of coating and materials that may lead to a desirable surface contact angle. The major application techniques used for this study pertain to dip coating, spray coating, spin coating and inkjet printing and silane and sol–gel base coating materials.

AbstractEarly bacterial infection (BI) identification in resource-limiting Emergency Departments (ED) is challenging, especially in low- and middle-income counties (LMIC). Misdiagnosis predisposes to antibiotic overuse and propagates antimicrobial resistance. This study evaluates new emerging biomarkers, secretory phospholipase A2 group IIA (sPLA2-IIA) and compares with other biomarkers on their performance characteristic of BI detection in Malaysia, an LMIC. A prospective cohort study was conducted involving 151 consecutive patients admitted to the ED. A single measurement was taken upon patient arrival in ED and was analysed for serum levels of sPLA2-IIA, high-sensitive C-reactive protein (CRP), procalcitonin (PCT), neutrophil percentage (N%), and lactate. All biomarkers’ performance was compared for the outcomes using area under the receiver operating characteristic curve (AUROC), sensitivity, and specificity. The performance of sPLA2-IIA (AUROC 0.93 [95% CI: 0.89–0.97]; Sn 80% [95% CI: 72–87]; Sp 94% [95% CI: 81–89]) was the highest among all. It was comparable with high-sensitive CRP (AUROC 0.93 [95% CI: 0.88–0.97]; Sn 75% [95% CI: 66–83]; Sp 91 [95% CI: 77–98]) but had a higher Sn and Sp. The sPLA2-IIA was also found superior to N%, PCT, and lactate. This finding suggested sPLA2-IIA was recommended biomarkers for BI detection in LMIC.

Published: May 2021

AbstractThe water level in the cultivation of eel (Anguilla bicolor bicolor) is an important study in order to provide the optimal water level for cultivation. Optimizing the water level will affect the substitution of respiration energy with energy to grow. In addition, the water level information is related to the efficiency of water use for eel production in the future. Information on water level for eel production is still very limited, so this research is necessary to do. A total of 120 eel elver (initial weight 13.66 ± 0.09 g) were collected from eel companies in Bogor City, Indonesia. Fish were reared in vertical aquaculture systems with a stocking density of 10 fish per container for 60 days. The artificial feed containing 55% protein given as much as 3–5% of the biomass. Absorption and water replacement were done 20% per day. The result of this research showed that fish weight increased with an average of 33.45 ± 0.33 g. Different water levels had an impact to KKb, SGOT, ALP, and He. There was erosion of the skin epidermis and necrosis of the gill filaments due to the adaptation process. Water quality was within the optimum range for all treatments and 1.5 cm water level is recommended for maintenance (SGOT, ALP and He values were closest to normal values).

Published: May 2021

AbstractWe explored the independent risk factors associated with cases of spontaneous abortion in infertile patients treated with human-assisted reproductive technology (ART) and established a smooth curve fit and perform a threshold effect analysis can provide guidance and a valuable reference for predicting the probability of spontaneous abortion. This was a retrospective cohort study of 16,097 patients successfully conceived with ART in Shangqiu First People's Hospital from June 2013 to December 2018. Overall, 2,378 (14.77%) had an abortion and 13,719 (85.23%) did not have an abortion. Multivariate logistic regression analysis showed that female age (OR 1.050; 95% CI 1.032–1.069; P < 0.001), male age (OR 1.100; 95% CI 1.086–1.115; P < 0.001), follicular-stimulating hormone (OR 1.049; 95% CI 1.022–1.076; P < 0.001), anti-Mullerian hormone (OR 0.893; 95% CI 0.862–0.925; P < 0.001) and the number of fetuses at pregnancy diagnosis were independent factors associated with spontaneous abortion. The threshold effect analysis found that when female age > 32 years (cut-off point) old, age and the risk of spontaneous abortion were positively correlated. When follicular-stimulating hormone > 6.1 IU/L (cut-off point), follicular-stimulating hormone was positively correlated with the occurrence of spontaneous abortion, When anti-Mullerian hormone ≤ 3.1 ng/mL (cut-off point), anti-Mullerian hormone was negatively correlated with the occurrence of spontaneous abortion and there was a linear positive correlation between antral Follicle Counting and live birth. In addition, the older the male age, the higher the incidence of abortion. The smooth curve fit and threshold effect analyses can provide a more detailed estimate of the probability of spontaneous abortion for pregnant couples.
New identification and significance of Early Cretaceous mafic rocks in the interior South China Block

Published: May 2021

AbstractEarly Cretaceous mafic rocks are first reported in the northern Guangxi region from the western Qin-Hang belt in the interior South China Block. A systematic investigation of zircon U–Pb dating, whole-rock geochemistry, Sm–Nd isotopes and zircon Hf–O isotopes for these mafic rocks reveals their petrogenesis and the mantle composition as well as a new window to reconstruct lithospheric evolution in interior South China Block during Late Mesozoic. Zircon U–Pb dating yielded ages of 131 ± 2 Ma to 136 ± 2 Ma for diabase and gabbro from Baotan area, indicating the first data for Early Cretaceous mafic magmatism in the western Qing-Hang belt. These mafic rocks show calc-alkaline compositions, arc-like trace element distribution patterns, low zircon εHf(t) of − 9.45 to − 6.17 and high δ18O values of + 5.72 to + 8.09‰, as well as low whole-rock εNd(t) values of − 14.27 to − 9.53. These data suggest that the studied mafic rocks are derived from an ancient lithospheric mantle source that was metasomatized during Neoproterozoic subduction. Thus, the occurrence of these mafic rocks indicates a reactivation of Neoproterozoic subducted materials during an extension setting at Late Mesozoic in the western Qin-Hang belt, an old suture zone that amalgamates the Yangtze and Cathaysia blocks.
Network clique cover approximation to analyze complex contagions through group interactions
Authors: Burgio Giulio , Arenas Alex , Gómez Sergio , Matamalas Joan T. 
Published: May 2021

AbstractContagion processes have been proven to fundamentally depend on the structural properties of the interaction networks conveying them. Many real networked systems are characterized by clustered substructures representing either collections of all-to-all pair-wise interactions (cliques) and/or group interactions, involving many of their members at once. In this work, focusing on interaction structures represented as simplicial complexes, we present a discrete-time microscopic model of complex contagion for a susceptible-infected-susceptible dynamics. Introducing a particular edge clique cover and a heuristic to find it, the model accounts for the higher-order dynamical correlations among the members of the substructures (cliques/simplices). The analytical computation of the critical point reveals that higher-order correlations are responsible for its dependence on the higher-order couplings. While such dependence eludes any mean-field model, the possibility of a bi-stable region is extended to structured populations.

The Onset–Offset N1–P2 Auditory Evoked Response in Individuals With High-Frequency Sensorineural Hearing Loss: Responses to Broadband Noise
Authors: Gonzalez Jennifer E. , Musiek Frank E. 
Published: May 2021

Purpose
Clinical use of electrophysiologic measures has been limited to use of brief stimuli to evoke responses. While brief stimuli elicit onset responses in individuals with normal hearing and normal central auditory nervous system (CANS) function, responses represent the integrity of a fraction of the mainly excitatory central auditory neurons. Longer stimuli could provide information regarding excitatory and inhibitory CANS function. Our goal was to measure the onset–offset N1–P2 auditory evoked response in subjects with normal hearing and subjects with moderate high-frequency sensorineural hearing loss (HFSNHL) to determine whether the response can be measured in individuals with moderate HFSNHL and, if so, whether waveform components differ between participant groups.

Method
Waveforms were obtained from 10 participants with normal hearing and seven participants with HFSNHL aged 40–67 years using 2,000-ms broadband noise stimuli with 40-ms rise–fall times presented at 50 dB SL referenced to stimulus threshold. Amplitudes and latencies were analyzed via repeated-measures analysis of variance (ANOVA). N1 and P2 onset latencies were compared to offset counterparts via repeated-measures ANOVA after subtracting 2,000 ms from the offset latencies to account for stimulus duration. Offset-to-onset trough-to-peak amplitude ratios between groups were compared using a one-way ANOVA.

Results
Responses were evoked from all participants. There were no differences between participant groups for the waveform components measured. Response × Participant Group interactions were not significant. Offset N1–P2 latencies were significantly shorter than onset counterparts after adjusting for stimulus duration (normal hearing: 43 ms shorter; HFSNHL: 47 ms shorter).

Conclusions
Onset–offset N1–P2 responses were resistant to moderate HFSNHL. It is likely that the onset was elicited by the presentation of a sound in silence and the offset by the change in stimulus envelope from plateau to fall, suggesting an excitatory onset response and an inhibitory-influenced offset response. Results indicated this protocol can be used to investigate CANS function in individuals with moderate HFSNHL.

Exploring conventional enhancement and separation methods for multi‐speech enhancement in indoor environments
Authors: Wei Yangjie , Zhang Ke , Wu Dan , Hu Zhongqi 
Published: May 2021

AbstractSpeech enhancement is an important preprocessing step in a wide diversity of practical fields related to speech signals, and many signal‐processing methods have already been proposed for speech enhancement. However, the lack of a comprehensive and quantitative evaluation of enhancement performance for multi‐speech makes it difficult to choose an appropriate enhancement method for a multi‐speech application. This work aims to study the implementation of several enhancement methods for multi‐speech enhancement in indoor environments of T60 = 0 s and T60 = 0.3 s. Two types of enhancement approaches are proposed and compared. The first type is the basic enhancement methods, including delay‐and‐sum beamforming (DSB), minimum variance distortionless response (MVDR), linearly constrained minimum variance (LCMV), and independent component analysis (ICA). The second type is the robust enhancement methods, including improved MVDR and LCMV realized by eigendecomposition and diagonal loading. In addition, online enhancement performance based on the iteration of single‐frame speech signals is researched, as is the comprehensive performance of various enhancement methods. The experimental results show that the enhancement effects of LCMV and ICA are relatively more stable in the case of basic enhancement methods; in the case of the improved enhancement algorithms, methods that employ diagonal loading iterations show better performance. In terms of online enhancement, DSB with frequency masking (FM) yields the best performance on the signal‐to‐interference ratio (SIR) and can suppress interference. The comprehensive performance test showed that LCMV and ICA yielded the best effects when there was no reverberation, while DSB with FM yielded the best SIR value when reverberation was present.
The stability analysis of stochastic opinion dynamics systems with multiplicative noise and time delays

Published: May 2021

AbstractThis paper studies the stochastic stability of opinion formation systems under both non‐time delay and time delay. Individuals whose opinions are affected by multiplicative noise are considered. Subsequently, a stochastic opinion formation model on coopetitive social networks which take both multiplicative noise and time delay into consideration and give the analysis of stochastic stability is introduced. When the continuous‐time system of opinion evolution is disturbed by stochastic multiplicative noise, the stability of the stochastic opinion formation system is dependent on the noise intensity and the topology structure. When the continuous‐time system of opinion dynamic is disturbed by time delay and multiplicative noise, the bounds of the noise intensity and time delay ensure the stochastic stability of the above system. Finally, numerical simulations are given to illustrate the above theoretical results.
Digital beam forming methods for variable polarimetric monopulse radar
Authors: Zhang Yi , Li Zhangfeng , Zheng Pei , Sun Houjun 
Published: May 2021

AbstractIn variable polarimetric monopulse radars, due to the number and types of data channels, the polarisation and angle information of the target in the receiving signals are non‐linearly coupled, which results in incorrect polarisation measurement and erroneous angle estimation through a linear digital beam forming (DBF) method. Based on a variable polarimetric monopulse radar with four channels, two non‐linear DBF methods are proposed to improve radar ability. Through the angle monopulse estimation principle and the reciprocity theorem, new pairs of summation and difference signals in all polarisation channels are formed to generate the correct polarimetric scattering and angle estimation results. The simulation and experiment results show that the proposed methods achieve a higher precision of polarisation measurement and more consistent angle estimation results compared to the linear DBF method.
Unerwünschte Arzneimittelwirkungen am Harntrakt – der Wittener Harntrakt-Nebenwirkungs-Score
Authors: Wiedemann Andreas , Dündar Vedat , Heese Melanie , Leufgens Thomas , Wirz Stefan , Brauckmann Robin , Heppner Hans-Jürgen 
Published: May 2021

ZusammenfassungObwohl der Harntrakt mit Restharnbildung, Harnverhaltung, Pollakisurie, Polyurie, Nykturie, Detrusorstimulation, Detrusorhemmung, Hämaturie, Dysurie und anderen Erscheinungen häufig den Schauplatz unerwünschter Arzneimittelwirkungen darstellt, fehlt es an einer Gesamtübersicht an Substanzen, die eine solche Harntraktnebenwirkung auslösen können und eine entsprechende Bewertung. Vorhandene Listen „potenziell inadäquater Medikation“ fokussieren entweder auf eine pharmakologische Gruppe von Nebenwirkungen („anticholinergic burden score“), eine Gruppe von Medikamenten bestimmter Indikation (LUTS-Forta) oder auf eine selektionierte Gruppe von Patienten (PRISKUS-Liste, beers-Liste).Mit dem folgenden interdisziplinären Projekt aus der Arbeitsgruppe Uro-Geriatrie der Universität Witten/Herdecke sollte diese Lücke geschlossen werden. Es erfolgte eine Identifikation von Substanzen, die eine Harntraktnebenwirkung lt. diverser Datenbanken prinzipiell auslösen können, eine Kategorisierung der hierzu vorhandenen Literatur (Kasuistik, Fallsammlung, RCT, Metaanalyse) und eine strukturierte Bewertung des Risikos durch 33 Experten. Das Ergebnis stellt eine Liste von 235 Substanzen dar, die zu verschiedenen Harntraktnebenwirkungen führen können. Diese Liste enthält einen die Nennung in Datenbanken bzw. deren Korrelat in der Literatur darstellenden „theroretischen“ Punktwert, einen die klinische Realität abbildenden „praktischen“ Punktwert, der die Expertenbewertung darstellt, und einen Summenscore – geordnet nach der Systematik der „Roten Liste“.Erstmals wäre damit sowohl bei der Neuverordnung einer Substanz vor dem Hintergrund bestehender patientenseitiger Risiken eine Einschätzung dieses Wirkstoffes im Hinblick auf Harntraktnebenwirkungen möglich; andersherum könnte die Durchsicht des Medikationsplanes bei Vorhandensein einer Harntraktfunktionsstörung die Frage klären, ob diese medikamentös (mit-) verursacht ist. Die Entwicklung des „Harntraktnebenwirkungs-Rechners“ als „App“ ist geplant.
Herausforderungen für die Schwerbehindertenvertretung vor dem
Hintergrund der gesetzlichen Neuerungen durch das
Bundesteilhabegesetz
Authors: Heide Marie Sophia , Niehaus Mathilde 
Published: May 2021

Zusammenfassung
Ziel der Studie Die Schwerbehindertenvertretung hat eine
Schlüsselrolle bei der Verwirklichung behinderungsgerechter und
inklusiver Arbeitsbedingungen. Durch das Bundesteilhabegesetz wurde dem Rechnung
getragen und die Rechte der Schwerbehindertenvertretung wurden ausgebaut. Ziel
der vorliegenden explorativen Analyse ist es, die veränderte
Rechtsstellung aus Perspektive der Schwerbehindertenvertretung zu beleuchten und
Herausforderungen in der praktischen Anwendung der gesetzlichen Neuerungen sowie
nicht berücksichtigte Bedarfe aufzudecken. Vor dem Hintergrund, dass
Forschung zur Implementation und Evaluation der Sozialgesetzgebung Kernelemente
der Rehabilitationsforschung sind, soll eine Lücke zwischen der
rechtlichen Implementation und der praktischen Anwendung geschlossen und der
Prozess einer lernenden Gesetzgebung vorangebracht werden.
Methodik Deutschlandweit wurden 1552 Schwerbehindertenvertretungen
schriftlich mittels Online-Survey befragt. Für die vorliegende Analyse
wurden vorrangig die Antworten zu Herausforderungen für die
Schwerbehindertenvertretung mit Hilfe der inhaltlich strukturierenden
qualitativen Inhaltsanalyse nach Kuckartz ausgewertet und anhand der
gesetzlichen Änderungen durch das Bundesteilhabegesetz analysiert.
Ergebnisse Das Bundesteilhabegesetz wird aus Sicht der
Schwerbehindertenvertretungen kritisch gewürdigt. Die Umfragedaten
verdeutlichen, dass die Schwerbehindertenvertretungen die gesetzlichen
Änderungen in Teilen als nicht umfassend genug bewerten. Einzelne
Regelungen, wie die Heranziehung von Stellvertretern und -vertreterinnen und die
Absenkung der Freistellungsgrenze, sind nicht weitreichend genug und betreffen
nur die Teilgruppe der Vertretungen in großen Betrieben. Bei anderen
Rechten wie dem Informations- und Anhörungsrecht fehlen
Sanktionsmöglichkeiten bei Nicht-Anwendung der Gesetze durch den
Arbeitgeber. Die Einführung der Unwirksamkeitsklausel in Bezug auf
Kündigungen wird als nicht ausreichend bewertet.
Schlussfolgerung Zwar werden die Rechte der Schwerbehindertenvertretung
durch das Bundesteilhabegesetz ausgebaut, doch gibt es noch Herausforderungen
bei der Umsetzung, der Präzisierung und der Verbindlichkeit der
einzelnen Neuerungen, die es im Sinne einer lernenden Gesetzgebung zu beachten
und weiter zu diskutieren gilt. Auf Grundlage der vorliegenden Ergebnisse bedarf
es eines weiteren Einbezugs der Schwerbehindertenvertretungen, um
Ansätze zur zielgerichteten Optimierung in der Anwendung sowie der
Ausgestaltung der gesetzlichen Neuerungen ableiten zu können.
Messinstrumente zur peripartalen Diagnostik von Depression, Angst und
Stress (Teil 1 einer Serie zur psychologischen Diagnostik im
Peripartalzeitraum)
Authors: Weigl Tobias , Garthus-Niegel Susan 
Published: May 2021

ZusammenfassungWährend der Schwangerschaft und nach der Geburt kann es bei Frauen und
Männern zu psychischen Beschwerden kommen. Am häufigsten finden
sich Ängste in Bezug auf die Schwangerschaft und die Geburt sowie
prä- und postpartal erhöhte Depressionswerte. Bei Populationen
mit besonderen Belastungen, wie den Eltern von Frühgeborenen, ist
darüber hinaus von einer stark erhöhten Stressbelastung
auszugehen. Zur standardisierten sowie zeitökonomischen Erfassung der
genannten Beschwerden sind geeignete Fragebögen nötig.
Allerdings liegen nur wenige für den deutschen Sprachraum validierte
Instrumente vor, die in Forschung und Klinik zudem nur wenig bekannt sind. Eine
Ausnahme stellt hier die Edinburgh Postnatal Depression Scale dar. Weiterhin
werden Männer zumeist nicht explizit in Fragebögen
berücksichtigt. Zur Vorbeugung sowie Behandlung psychischer Beschwerden
im Peripartalzeitraum stellen geeignete Screening-Instrumente eine wichtige
Voraussetzung dar. Auf dieser Grundlage können bei den Betroffenen akute
Belastungen abgemildert und chronische Verläufe mit Folgen für
das Kind oder die Paarbeziehung verhindert werden. Hierfür scheint
zukünftig eine Vereinheitlichung hinsichtlich der verwendeten
Instrumente nötig.
