Authors: Zhan Xiaoping , Xu Yun , Qi Qi , Wang Yaolin , Shi Huiying , Mao Zhenmin 
Published: January 2018

A series of novel quinazolinone derivatives containing a substituted amino moiety were synthesized, evaluated for their cytotoxic and antibacterial activities. The results of MTT assay showed that all synthesized target compounds 5A – 5O showed potent cytotoxicity against SGC‐7901 (IC50, 0.72 – 1.41 μm). Moreover, the compounds 5D, 5I, and 5K showed better selectivity as compared with positive controls pemetrexed and MTX due to weak cytotoxicity against normal tissue cell line HUVSMC. Among synthesized compounds, the compounds 5E, 5J, 5L, and 5N showed broad‐spectrum cytotoxic activities against at least four cancer cell lines at a micromolar level. The results of antibacteria evaluation revealed that all synthesized compounds showed good to moderate antibacterial activities against Gram‐negative bacteria Escherichia coli. Among them, the MIC values of the compounds 5C, 5F, and 5M were 0.31 μg/mL.

Authors: Börger Alexander , Burow Daniel 
Published: January 2018

AbstractDer vermehrte Einsatz von absorbant glass mat (AGM)‐Bleistarterbatterien erfordert eine Erweiterung des üblichen Methodenspektrums der Batterieprüfung. Die Bestimmung des Säurefüllgrads hat sich zu einem Standardverfahren der Qualitätskontrolle von AGM‐Batterien entwickelt. Die Verteilung der Säurefüllgrade über die Batteriezellen lässt sich jedoch auch als Kriterium zur Beurteilung von Alterungsmechanismen heranziehen. Die Säurefüllgrade sowohl im Labor als auch im Feld gealterter Batterien wurden bestimmt und Hypothesen zur Korrelation mit verschiedenen Betriebsszenarien aufgestellt.

Published: January 2018

AbstractDurch klimabedingte Schwankungen in der Wind‐ und Solarenergie und den steigenden Bedarf an erneuerbaren Energien rücken alternative Systeme wie die bedarfsorientierte Biogaserzeugung immer weiter in den Fokus. Daher werden die aktuell untersuchten Konzepte zur Flexibilisierung von Biogasanlagen aufgezeigt. Zu den Ansätzen gehören die Biogasspeicherung sowie die bedarfsorientierte Biogasproduktion durch Fütterungsmanagement, variable Verstromung, Desintegrations‐ oder Festbettfermenter‐Verfahren. Auch die Kopplung mit Power‐to‐Gas‐ oder Power‐to‐Heat‐Systemen erscheint vielversprechend.

Published: January 2018

AbstractDer melodische Leitfähigkeitsprüfer (LF‐Prüfer) ist nicht nur in der Lage qualitativ zu überprüfen, ob ein Stoff elektrisch leitfähig ist, sondern ermöglicht auch quantitative Aussagen. Zwar lässt sich nicht wie bei einem kommerziellen Konduktometer die genaue Leitfähigkeit ablesen, je nach Leitfähigkeit sind jedoch unterschiedliche auditive Charakteristika wahrnehmbar. Sogar die elektrische Leitfähigkeit von entionisiertem Wasser lässt sich nachweisen!
Maximizing availability for task scheduling in on‐demand computing–based transaction processing system using ant colony optimization
Authors: Mahato Dharmendra Prasad , Singh Ravi Shankar 
Published: January 2018

SummaryMaximization of availability and minimization of the makespan for transaction scheduling in an on‐demand computing system is an emerging problem. The existing approaches to find the exact solutions for this problem are limited. This paper proposes a task scheduling algorithm using ant colony optimization (MATS_ACO) to solve the mentioned problem. In this method, first, availability of the system is computed, and then, the transactions are scheduled using the foraging behavior of ants to find the optimal solutions. We also modify two known meta‐heuristic algorithms such as genetic algorithm (GA) and extremal optimization (EO) to obtain transaction scheduling algorithms for the purpose of comparison with our proposed algorithm. The compared results show that the proposed algorithm performs better than others.
Deep Bayesian network architecture for Big Data mining

Published: January 2018

SummaryClassical Datamining methods are facing various challenges in the era of Big Data. Between the need of fast knowledge extraction and the high flows of data acquired in small slots of time, these methods became shifted. The variability and the veracity of the Big Data perplex the Machine Learning process. The high volume of Big Data yields to a congested learning because the classic methods are designed for small sets of features. Deep Learning has recently emerged in the aim of handling voluminous data. The concept of the Deep induces the conversion of the features into a new abstracted representation in order to optimize an objective. Although the Deep Learning methods are experimentally promising, their parameterization is exhaustive and empirical. To tackle these problems, we utilize the causality and the uncertainty of the Bayesian Network in order to propose a new Deep Bayesian Network architecture. We provide a new learning algorithm for this multi‐layered Bayesian Network with latent variables. We evaluate the proposed architecture and learning algorithms over benchmark datasets. We used high‐dimensional data in order to simulate the Big Data challenges, which are imposed by the volume and veracity aspects. We demonstrate the effectiveness of our contribution under these constraints.

Polypropylene Nonwoven Fabric@Poly(ionic liquid)s for Switchable Oil/Water Separation, Dye Absorption, and Antibacterial Applications
Authors: Ren Yongyuan , Guo Jiangna , Lu Qian , Xu Dan , Qin Jing , Yan Feng 
Published: January 2018

AbstractPollutants in wastewater include oils, dyes, and bacteria, making wastewater cleanup difficult. Multifunctional wastewater treatment media consisting of poly(ionic liquid)‐grafted polypropylene (PP) nonwoven fabrics (PP@PIL) are prepared by a simple and scalable surface‐grafting process. The fabricated PP@PIL fabrics exhibit impressive switchable oil/water separation (η>99 %) and dye absorption performance (q=410 mg g−1), as well as high antibacterial properties. The oil/water separation can be easily switched by anion exchanging of the PIL segments. Moreover, the multiple functions (oil/water separation, dye absorption, and antibacterial properties) occurred at the same time, and did not interfere with each other. The multifunctional fibrous filter can be easily regenerated by washing with an acid solution, and the absorption capacity is maintained after many recycling tests. These promising features make PIL‐grafted PP nonwoven fabric a potential one‐step treatment for multicomponent wastewater.

Authors: ASANO SHIHO , ITO YOSHIHIRO 
Published: January 2018

SUMMARYThis paper develops a wireless local area network (LAN) base station with quality of service control based on Web quality of experience (QoE) by bandwidth control and priority control; it evaluates the performance of the developed system by experiments with subjects. By using the relationship between importance of data of a Web service and the distribution of the length of IP packets, the base station can reduce the bandwidth consumption over a wireless LAN without worsening of QoE. The authors have implemented by adopting two technologies for priority control: OpenFlow and Wi‐Fi multimedia. In the experiment, the authors treat three actual Web services and assess QoE for them. From the experimental results, the authors show the effectiveness of the developed base station.

Living under threat: Mutual threat perception drives anti‐Muslim and anti‐Western hostility in the age of terrorism
Authors: Obaidi Milan , Kunst Jonas R. , Kteily Nour , Thomsen Lotte , Sidanius James 
Published: January 2018

AbstractThis research demonstrates a common psychology of outgroup hostility driven by perceived intergroup threat among three groups and seven cultural contexts: non‐Muslim Westerners, Muslims in Western societies, and Muslims in the Middle East. In Study 1, symbolic, but not realistic and terroristic threats, predicted non‐Muslim Norwegians' intentions to join anti‐Islamic movements. In Study 2, symbolic and realistic, but not terroristic threat, predicted non‐Muslim Americans' willingness to persecute Muslims. In Studies 3 and 4, symbolic threat predicted support and behavioral intentions against the West among Swedish and Turkish Muslims. Finally, in Study 5, a comparison demonstrated that symbolic and realistic threats had the same effects on violent intentions among non‐Muslim and Muslim Danes, and Muslims in Afghanistan. Meta‐analysis showed that symbolic threat was most strongly associated with intergroup hostility. Across studies, participants with high religious group identification experienced higher levels of threat. Implications for intergroup research and prejudice reduction are discussed.
Structural equation modeling of office environment quality, sick building syndrome, and musculoskeletal complaints on aggregate satisfaction of office workers
Authors: Shin Dong Seok , Jeong Byung Yong , Park Myoung Hwan 
Published: January 2018

AbstractThis study aims to analyze the effects of office environment quality (OEQ), sick building syndrome (SBS), and musculoskeletal complaints on aggregate office satisfaction level using the structural equation. A questionnaire survey targeting 483 office workers of 18 public agencies was conducted and surveyed on workers’ characteristics (gender, age, work experience, work hours, and computer time of day), OEQ satisfaction level (temperature and humidity, lighting, noise, and air quality), SBS frequency (eye, noise, throat, skin, and headache), musculoskeletal complaints intensity (neck, shoulder, arm, wrist, waist, and leg), and aggregate office satisfaction level. As a result of the model using the structural equation, the level of OEQ on temperature and humidity, noise, and air quality directly affect the level of SBS frequency. Also, the OEQ level indirectly affects both musculoskeletal complaints’ intensity and aggregate office satisfaction level via the level of SBS frequency. Thus, providing pleasant office environments can be an effective measure to enhance office workers’ satisfaction, because workers’ levels for musculoskeletal complaints and aggregate office satisfaction depend on OEQ and SBS levels.

Published: January 2018

AbstractPerennial pools are common natural features of peatlands, and their hydrological functioning and turnover may be important for carbon fluxes, aquatic ecology, and downstream water quality. Peatland restoration methods such as ditch blocking result in many new pools. However, little is known about the hydrological function of either pool type. We monitored six natural and six artificial pools on a Scottish blanket peatland. Pool water levels were more variable in all seasons in artificial pools having greater water level increases and faster recession responses to storms than natural pools. Pools overflowed by a median of 9 and 54 times pool volume per year for natural and artificial pools, respectively, but this varied widely because some large pools had small upslope catchments and vice versa. Mean peat water‐table depths were similar between natural and artificial pool sites but much more variable over time at the artificial pool site, possibly due to a lower bulk specific yield across this site. Pool levels and pool‐level fluctuations were not the same as those of local water tables in the adjacent peat. Pool‐level time series were much smoother, with more damped rainfall or recession responses than those for peat water tables. There were strong hydraulic gradients between the peat and pools, with absolute water tables often being 20–30 cm higher or lower than water levels in pools only 1–4 m away. However, as peat hydraulic conductivity was very low (median of 1.5 × 10−5 and 1.4 × 10−6 cm s−1 at 30 and 50 cm depths at the natural pool site), there was little deep subsurface flow interaction. We conclude that (a) for peat restoration projects, a larger total pool surface area is likely to result in smaller flood peaks downstream, at least during summer months, because peatland bulk specific yield will be greater; and (b) surface and near‐surface connectivity during storm events and topographic context, rather than pool size alone, must be taken into account in future peatland pool and stream chemistry studies.
Representing causal knowledge in environmental policy interventions: Advantages and opportunities for qualitative influence diagram applications
Authors: Carriger John F , Dyson Brian E , Benson William H 
Published: January 2018

Abstract

This article develops and explores a methodology for using qualitative influence diagrams in environmental policy and management to support decision-making efforts that minimize risk and increase resiliency. Influence diagrams are representations of the conditional aspects of a problem domain. Their graphical properties are useful for structuring causal knowledge relevant to policy interventions and can be used to enhance inference and inclusivity of multiple viewpoints. Qualitative components of influence diagrams are beneficial tools for identifying and examining the interactions among the critical variables in complex policy development and implementation. Policy interventions on social–environmental systems can be intuitively diagrammed for representing knowledge of critical relationships among economic, environmental, and social attributes. Examples relevant to coastal resiliency issues in the US Gulf Coast region are developed to illustrate model structures for developing qualitative influence diagrams useful for clarifying important policy intervention issues and enhancing transparency in decision making. Integr Environ Assess Manag 2018;14:381–394. Published 2018. This article is a US Government work and is in the public domain in the USA.

Key Points
A qualitative influence diagram (QID) provides structural explanations about a problem domain. QIDs can be beneficial tools for policy development and implementation. Causal pathway analysis with QIDs can help target uncertainties that are important to evaluate and track for policy design and implementation. QIDs can easily be adapted to dynamic situations and updated as new data and knowledge become available.
Surrogate scale for evaluating respiratory function based on complete blood count parameters
Authors: Guang Yang , Jie Zhou , Feng Dong , Hui Liu 
Published: January 2018

BackgroundIn this study, we aimed to identify a simple method for evaluating respiratory function using complete blood count parameters.MethodsThe complete blood count parameters, including red blood cell (RBC) count, hemoglobin (Hb) level, lymphocyte (Lym) and platelet (Plt) count, and partial pressure of oxygen (PO2) level, were measured using automated analyzers in patients with chronic obstructive pulmonary disease (COPD), aged subjects, and young subjects (control group). The red cell index (RCI) was calculated using the following equation: (RBC × Hb)/(Lym × Plt); in theory, the RCI is inversely proportional to the respiratory function.ResultsWe observed a significant relationship between the RCI and PCO2 values, and between the RCI and FEV1/FVC values (P < .05). The RCI in the COPD, and aged subject groups were all significantly higher than that in the control group (P < .05). The cutoff value for normal respiratory function was 2.3. The positive rates for an abnormal increase in RCI were also considerably higher in each observation group than in the control group (P < .05).ConclusionThe RCI can be considered as a simple and effective tool for evaluating respiratory function.
An accurate determination of the phase center position of transitions into 2‐dimensional regions
Authors: Uyguroğlu Rasime , Embais Khadija 
Published: January 2018

AbstractCorrect estimation of the phase centers of the input and output ports is important in Rotman‐type bootlace lens applications. Any shift in the position of the phase center of a port used as a transition between the feed lines and the 2‐dimensional region will cause phase errors, which will create adverse effects on the radiation patterns. This paper introduces a method for determining the phase centers of the transitions radiating into parallel plate regions. A study has been conducted for linearly tapered and multistep transitions (ie, radiators). The results of the study show that the estimated phase centers are displaced from the aperture of the transitions. This displacement is smaller for the multistep transitions compared with the linearly tapered transitions. The simulation results of these transitions also show that, the use of the estimated phase center position reduces the phase errors significantly over wide coverage angles. The results also show that the phase errors do not change with the distance from the aperture. On the other hand, phase errors varies with frequency. These errors are smaller for the stepped transitions compared with the linearly tapered transitions. A separate simulation study of radiation patterns of a linear array fed by a Rotman lens has shown that deterioration occurs in sidelobes and minima levels and a small shift in the off‐axis beam positions when short transitions are used without phase center position correction.
