AbstractDue to the obvious advantages of utilizing naturally abundant and low cost sodium resources, sodium ion batteries (SIBs) show great potential for large‐scale energy storage applications. And the high theoretical capacities of transition metal sulfides (TMSs) make them appealing anode materials for SIBs; however, structural collapse caused by the severe volume change during de/sodiation processes results in poor capacity retention and rate capabilities. Compared to the development of new materials and the improvement of their electrochemical performance, the studies on their reaction mechanisms are still rare, especially the operando characterizations. Herein, the synthesis, anode application, and the operando observation of the de/sodiation mechanism of a nitrogen‐doped porous carbon coated nickel cobalt bimetallic sulfide hollow nanocube ((Ni0.5Co0.5)9S8@NC) composite are reported. Such a material is synthesized via facile sulfidation of phenol formaldehyde coated Ni3[Co(CN)6]2 metal–organic framework precursors with Na2S followed by calcination. The nanocomposite displays a remarkable specific capacity of 752 mAh g−1 at 100 mA g−1 after 100 cycles and outstanding rate capability due to the synergistic effect of several appealing features. Particularly, the pseudocapacitive effect appears to substantially contribute to the sodium storage capability. Operando X‐ray diffraction reveals the conversion reaction mechanism of (Ni0.5Co0.5)9S8@NC, forming Ni, Co, Na2S, and Na2S5.
Centralized and decentralized distributed control of longitudinal vehicular platoons with non‐uniform communication topology
Authors: Chehardoli Hossein , Ghasemi Ali , Najafi Ali 
Published: September 2019

AbstractIn this paper, the distributed control of a longitudinal platoon of vehicles with non‐uniform communication topology is studied. In the case of non‐uniform communication topology, some eigenvalues of the network's matrix may be complex which complicates the stability analysis of the platoon. Most previous studies on vehicular platooning focus mainly on uniform topologies such as uni‐directional, bi‐directional, and multi predecessors following. Since all eigenvalues of these topologies are real, the stability analysis can be performed in a straightforward manner. A third‐order linear differential model is employed to describe the upper‐level dynamics of each vehicle. The 3 N‐order closed‐loop dynamics of the platoon are decoupled to individual third‐order dynamics by presenting a new approach. Two new centralized and decentralized control protocols are introduced to perform the stability analysis of the closed‐loop dynamics. A constant time headway strategy is employed to adjust the inter‐vehicle spacing. Simulation results with different scenarios are presented to illustrate the effectiveness of the proposed approaches.

AbstractHigh‐valent cobaltIV‐bpy complex stabilized in silica matrix was detected as catalytically active form and intermediate in cobalt‐mediated oxidative C−H/NH cross‐coupling reaction. These CoIV species prepared by electrooxidation of CoIII(bpy)3‐doped silica nanoparticles (SNs) at relatively low anodic potentials have demonstrated high catalytic activity. Both size and architecture of the SNs are highlighted as the factors beyond the complex structure affecting its oxidation potential and catalytic efficiency. The factors have been optimized for the catalyst with high efficiency, easy separation and reusability for 7 times at least. The optimal nanocatalyst (1 mol%) provides 100 % conversion of reactants in a single step of ligand‐directed coupling of H2NTs with arenes under electrochemical regeneration conditions. The results emphasize both synthetic route for efficient embedding of CoIII(bpy)3 into silica support and the electrochemical generation of CoIV complexes as a facile route for developing the efficient nanocatalyst of oxidative functionalization. The observed reactivity has the potential in development of Co‐catalyzed coupling reactions.

Authors: Theßeling Christin , Grünewald Marcus 
Published: September 2019

AbstractIn experimentellen Versuchen wurde die Genauigkeit eines Leitfähigkeits‐Gittersensors mit einer zeitlichen und räumlichen Auflösung von 5 kHz und 4,8 mm in Bezug auf die Bestimmung von Blasengrößen untersucht. Als Referenzwert werden einzelne Luftblasen definierten Gasvolumens im Größenbereich von 2 – 12 mm in eine ruhende Flüssigkeit aufgegeben. Die Ergebnisse zeigen eine erhöhte Messunsicherheit für Blasen, deren Durchmesser kleiner als die Auflösung des Gitternetzes ist. Die ermittelte Blasengröße hängt in diesem Fall stark von der örtlichen Position der aufsteigenden Gasblasen im Gitternetz ab.
How pressure from stakeholders affects integrated reporting quality
Authors: Vitolla Filippo , Raimo Nicola , Rubino Michele , Garzoni Antonello 
Published: September 2019

AbstractIntegrated reporting (IR) is considered an innovative and effective reporting tool that includes financial and nonfinancial information. Recently, there has been a heightened emphasis on IR from both academic and professional viewpoints. However, despite the importance of stakeholders in the practice of IR, their impact on the report drafting process has not been analysed in any study. Therefore, this study aims to fill this gap by analysing the relationship between stakeholders' pressure and IR quality. On the basis of the stakeholder theory, this study uses a regression model to demonstrate how the IR quality is significantly and positively associated with the stakeholders' pressures. Specifically, results of this study indicate that pressures from customers, environmental protection organizations, employees, shareholders, and governments determine the IR quality. To the best of our knowledge, this is the first study that investigates stakeholders' pressure as a determinant of IR quality.
Recruiting millennials: Exploring the impact of CSR involvement and pay signaling on organizational attractiveness
Authors: Waples Christopher J. , Brachle Benjamin J. 
Published: September 2019

AbstractModern organizations must consider corporate social responsibility (CSR) and its implications. CSR involvement carries many potential benefits, including opportunities to promote stakeholder engagement with the organization, particularly among young people (i.e., millennials) in the emergent workforce. Collectively, millennials are often described as both socially active and self‐centered. These seemingly antithetical motives complicate the execution of optimal recruitment practice. This empirical study examined the impact of CSR activity and relative pay level signals on organizational attractiveness. Participants who were seeking or soon to be seeking employment in the United States responded to a hypothetical company profile. Confirming expectations, results revealed an effect of CSR information on organizational attractiveness, wherein notification of CSR involvement enhanced attractiveness. Pay level and CSR notification did not significantly interact, indicating that the effects of CSR on attractiveness are not moderated by information about pay levels. The implications of the results and future research recommendations are discussed.
Corporate social responsibility and firm value: Do firm size and age matter? Empirical evidence from European listed companies
Authors: D'Amato Antonio , Falivena Camilla 
Published: September 2019

AbstractAlthough the current empirical literature has focused predominantly on the direct relationship between corporate social responsibility (CSR) and firm value, in this paper, we aim to explore firm‐level moderators that may contribute to disentangling this relationship. On the basis of a dataset of Western European listed companies, we use a moderation analysis of panel data to examine whether firm size and age drive the impact of CSR on firm value. Our estimations show that the relationship between CSR and firm value is moderated by firm size and age so that it is negatively impacted when small and/or young companies are considered. This finding seems to be consistent with the view that CSR initiatives could be ineffective in smaller and younger companies due to their lack of financial resources, experience, reputation, and so forth. Implications for firms are also discussed.
A longitudinal examination of the relationship between eating disorder symptoms and suicidal ideation
Authors: Ortiz Shelby N. , Smith April 
Published: September 2019

AbstractObjectiveCross‐sectional research demonstrates significant correlations between eating disorders (EDs) and suicidal thoughts and behaviors. Although suicide ideation (SI) is a risk factor for suicidal behavior, longitudinal research investigating SI among EDs is limited. Thus, the aim of this study was to offer insight into the dynamic relationship between EDs and SI by investigating if these variables predicted one another at weekly time points.MethodAutoregressive cross‐lagged modeling was used to test bidirectional relationships between ED symptoms and suicidal ideation among an ED patient sample (n = 92). Participants completed a measure of suicidal ideation and the Eating Disorder Examination—Questionnaire (EDE‐Q) weekly for 5 weeks.ResultsSI and ED symptoms were correlated with each other at each time point. Unexpectedly, the majority of cross‐lagged pathways were nonsignificant. However, SI at Week 4 predicted ED symptoms at Week 5, while controlling for Week 4 ED symptoms. This pattern of results was found when the shape concerns, weight concerns, and eating concerns subscales of the EDE‐Q were entered into the model. Moreover, Week 2 shape concerns predicted Week 3 SI and Week 3 eating concerns predicted Week 4 SI. No significant cross‐lagged pathways were found with the dietary restraint subscale.DiscussionNonsignificant cross‐lagged pathways may indicate that third variables better explain the relations between certain ED symptoms and SI over time. However, there were instances where ED symptoms and SI predicted one another. Given this, targeting suicidal thoughts in therapy may help to reduce eating pathology and vice versa.

AbstractBackgroundIt is estimated about 7% of the world population is carriers of hemoglobin diseases. Alpha‐thalassemia is one of the most common hereditary hemoglobin disorders in the world. This study investigated alpha‐globin mutations in potential carriers with hypochromic and microcytic anemia from Mazandaran, in northern Iran.MethodsA total of 859 subjects were selected; genomic DNA was extracted and examined for the presence of mutations in the alpha‐globin genes.ResultsMutation analysis of alpha‐globin genes revealed 27 different mutations. Seven variants were seen in 91.45% of all alpha‐1 and alpha‐2 mutations among patients in this study. The 3.7 kb deletion is the most frequent mutation with a frequency of 49.53%, followed by PolyA2 (15.19%), −4.2 deletion (8.76%), ‐‐MED (5.84%), IVSI‐5nt deletion (5.49%), Hb constant spring (3.62%), and Cd 19 (−G; 3.04%), respectively. There are also seven new variants which were reported for the first time either in alpha‐1 or alpha‐2 genes, including codon 9 (C > A; α2), deletion of codon 60 (AAG deletion; α2), duplication of codon 94‐100 plus 3 base pairs of intron 2 (IVSII + 3; α1), codon 99 (C > A; α2), codon 108 (A > G; α2), codon 128 (A > T; α2), and codon 129 (T > G; α2), respectively. The MLPA method also revealed three rare and novel deletions in alpha‐cluster region with about 30 kilobases long.ConclusionThis study showed an efficient identification of α‐thalassemia can be achieved using standard hematological indices in our population. The details of these variations will help local genetic services for diagnostic and prenatal diagnosis services.
Schiff base derived from salicylaldehyde‐based azo dye as chromogenic anionic sensor and specific turn‐on emission sensor for cyanide ion
Authors: Chakraborty Nilanjan , Chakraborty Arijit , Das Suman 
Published: September 2019

AbstractA novel Schiff base has been derived from condensing 4‐aminoantipyrine with diazotized salicylaldehyde. The derived compound acted as a colorimetric sensor for hazardous aqueous anions like CN−, F−, and CH3COO− among a list of anions. The colorimetric changes were further verified through absorption titrations. The detection limits were of the order of 10−10 M, which makes the sensor significant. The interaction of the anions with the sensor was stoichiometrically 1:1 with good binding constants. The sensor turns out to be a specific turn‐on emission sensor for CN− even in competitive environments. The F− ion sensing ability was extended to the determination of F− in a commercial toothpaste with good results.
Design and synthesis of novel sugar‐based nitrogen‐containing heterocycles as potential anticancer agents under microwave in water
Authors: Liu Jian , Wu Chunlei , Jin Huimin , Du Kui , Zheng Hui 
Published: September 2019

A series of novel glycosyl nitrogen‐containing heterocycles derivatives were designed and synthesized. With the help of microwave, the reaction was carried out in water rapidly and afforded the target compounds in good yields. The acid catalysts that were essential for this kind of reaction under traditional heating method were avoided through this strategy. Preliminary biological evaluation showed that most of the compounds could inhibit the growth of A549 cells, but the inhibition of HepG‐2 cells was relatively poor. Notably, compound 2i displayed the best potency with an IC50 value of 3.42 μM against A549 cell lines, which is comparable with the common anticarcinogen paclitaxel (5.12 μM). Molecular modeling studies suggested that 2i may bind to the ATP‐binding site of epidermal growth factor receptor (EGFR), indicating a rational design strategy. These results provide a starting point for designing glycosyl nitrogen‐containing heterocycles as the potential drugs in lung cancer therapy.
A Fluorescence‐Based Assay for Quantitative Analysis of Phospholipid:Diacylglycerol Acyltransferase Activity
Authors: Falarz Lucas , Xu Yang , Singer Stacy D. , Chen Guanqun 
Published: September 2019

AbstractPhospholipid:diacylglycerol acyltransferase (PDAT) catalyzes the acyl‐CoA‐independent triacylglycerol (TAG) biosynthesis in plants and oleaginous microorganisms and thus is a key target in lipid research. The conventional in vitro PDAT activity assay involves the use of radiolabeled substrates, which, however, are expensive and demand strict regulation. In this study, a reliable fluorescence‐based method using nitrobenzoxadiazole‐labeled diacylglycerol (NBD‐DAG) as an alternative substrate was established and subsequently used to characterize the enzyme activity and kinetics of a recombinant Arabidopsis thaliana PDAT1 (AtPDAT1). We also demonstrate that the highly toxic benzene used in typical PDAT assays can be substituted with diethyl ether without affecting the formation rate of NBD‐TAG. Overall, this method works well with a broad range of PDAT protein content and shows linear correlation with the conventional method with radiolabeled substrates, and thus may be applicable to PDAT from various plant and microorganism species.
Inverted duplication, triplication and quintuplication through sequential breakage‐fusion‐bridge events induced by a terminal deletion at 5p in a case of spontaneous abortion

Published: September 2019

AbstractBackgroundIntegrated chromosome, fluorescence in situ hybridization (FISH) and array comparative genomic hybridization (aCGH) analyses have been effective in defining unbalanced chromosomal rearrangements. Discordant chromosome and aCGH results are rarely reported.MethodsRoutine cytogenomic analyses and literature review were performed in the study of a case from products of conception (POC).ResultsChromosome and FISH analysis revealed a mosaic pattern consisting of a primary aberration of an inverted duplication of 5p and derived secondary and tertiary aberrations from sequential triplication and quintuplication of 5p, respectively. The aCGH analysis detected only a 1.521 Mb terminal deletion at 5p15.33 with no other pathogenic copy number variants in the genome. This mosaic karyotypic pattern likely resulted from chromosome instability induced by sequential breakage‐fusion‐bridge events during in vitro cell culture. A review of literature found heterogeneous distal deletion and inverted duplication of 5p in prenatal and pediatric cases.ConclusionThis is the first case reported in POC with a unique mosaic pattern and discordant chromosome and aCGH results. Caution should be applied in reporting and interpreting these discordant results and further analysis for underlying mechanism should be considered.

A perceptual computing–based method to prioritize intervention actions in the probabilistic risk assessment techniques
Authors: Yazdi Mohammad 
Published: September 2019

AbstractProbabilistic risk assessment techniques as the systematic tools have been widely used on the different type of industrial sectors to reduce the estimated risk to an acceptable level. The fact is to design inherently safety; hazards have to be eliminated and reduced in risk as much as possible with the consideration of several interventions. In this regard, multicriteria decision making (MCDM) science is commonly integrated with the probabilistic risk assessment techniques to improve the safety performance of a system. Thus, it has been widely used to assist decision makers in controlling the identified process hazards in a different type of engineering applications. However, by increasing the complexity of industrial sectors as well as human being judgments, typical MCDM methods cannot highly guarantee their output results. According to this point, proposing MCDM methods based on mathematical programming have been interested in scholars due to high reliability and feasibility of the results. In this paper, we extended integration of MULTIMOORA approach with the Choquet integral under subjectivity circumstances to prioritize corrective actions in a typical probabilistic risk assessment technique. To illustrate the efficiency and feasibility of the proposed method, it has been applied in a real case study.
From ecology to remote sensing: using animals to map land cover
Authors: Remelgado Ruben , Safi Kamran , Wegmann Martin 
Published: September 2019

AbstractLand cover is a key variable in monitoring applications and new processing technologies made deriving this information easier. Yet, classification algorithms remain dependent on samples collected on the field and field campaigns are limited by financial, infrastructural and political boundaries. Here, animal tracking data could be an asset. Looking at the land cover dependencies of animal behaviour, we can obtain land cover samples over places that are difficult to access. Following this premise, we evaluated the potential of animal movement data to map land cover. Specifically, we used 13 White Storks (Cicona cicona) individuals of the same population to map agriculture within three test regions distributed along their migratory track. The White Stork has adapted to foraging over agricultural lands, making it an ideal source of samples to map this land use. We applied a presence–absence modelling approach over a Normalized Difference Vegetation Index (NDVI) time series and validated our classifications, with high‐resolution land cover information. Our results suggest White Stork movement is useful to map agriculture, however, we identified some limitations. We achieved high accuracies (F1‐scores > 0.8) for two test regions, but observed poor results over one region. This can be explained by differences in land management practices. The animals preferred agriculture in every test region, but our data showed a biased distribution of training samples between irrigated and non‐irrigated land. When both options occurred, the animals disregarded non‐irrigated land leading to its misclassification as non‐agriculture. Additionally, we found difference between the GPS observation dates and the harvest times for non‐irrigated crops. Given the White Stork takes advantage of managed land to search for prey, the inactivity of these fields was the likely culprit of their underrepresentation. Including more species attracted to agriculture – with other land‐use dependencies and observation times – can contribute to better results in similar applications.
The First Bis(μ‐acetato)(μ‐oxido)diruthenium(III) Complexes Containing Sulfur Donor Ligands

Published: September 2019

AbstractNovel diruthenium(III) complexes of general formula [RuIII2(μ‐O)‐(μ‐CH3CO2)2(bpy)2L2](PF6)2 (L: tetrahydrothiophene, (3); 4,5‐dihydro‐3(2H)‐thiophenone, (4); thiazole, (5); 4‐methylthiazole, (6); bpy: 2,2’‐bipyridine), which contain sulfur or nitrogen donor ligands at the trans‐to‐oxido sites, have been synthesized. The Ru–S bond distance in 4 is determined by X‐ray crystallography to be 2.447 Å, and the Ru–N(trans‐to‐oxido) length in 5 (2.157 Å) is similar to that of the complex having pyridine as the L ligand, 1. The spectroscopic properties and redox behavior of the complexes bearing sulfur donor ligands have been investigated and compared with those containing nitrogen donor ligands. The potentials of the redox couples of Ru2II,III/Ru2III,III and Ru2III,III/Ru2III,IV for 3 and 4 shift to positive regions compared with those of complexes with nitrogen donor ligands, 1, 5 and 6. The density functional theory (DFT) calculations reveal that the contribution of the trans ligand to the visible absorption is larger in 3 and 4 than in 1, 2 (L: CH3CN), 5 and 6.
