Eye‐tracking studies have demonstrated that individuals with autism spectrum disorder sometimes show differences in attention and gaze patterns. This includes preference for certain nonsocial objects, heightened attention to detail, and more difficulty with attention shifting and disengagement, which may be associated with restricted and repetitive behaviors. This study utilized a visual exploration task and replicates findings of reduced number of objects explored and increased fixation duration on high autism interest objects in a large sample of individuals with autism spectrum disorder (n = 129, age 6–54 years) in comparison with a typically developing group. These findings correlated with parent‐reported repetitive behaviors. Additionally, we applied recurrent quantification analysis to enable identification of new eye‐tracking features, which accounted for temporal and spatial differences in viewing patterns. These new features were found to discriminate between autism spectrum disorder and typically developing groups and were correlated with parent‐reported repetitive behaviors. Original and novel eye‐tracking features identified by recurrent quantification analysis differed in their relationships to reported behaviors and were dependent on age.

Autism Research 2018, 11: 1554–1566. © 2018 International Society for Autism Research, Wiley Periodicals, Inc.Lay SummaryUsing eye‐tracking technology and a visual exploration task, we showed that people with autism spectrum disorder (ASD) spend more time looking at particular kinds of objects, like trains and clocks, and look at fewer objects overall than people without ASD. Where people look and the order in which they look at objects were related to the restricted and repetitive behaviors reported by parents. Eye‐tracking may be a useful addition to parent reports for measuring changes in behavior in individuals with ASD.

AbstractA Li2MnSiO4/Al2O3 nanocomposite (LMSA) was prepared as positive electrode material for aqueous supercapatteries by hydrothermal synthesis of Li2MnSiO4 nanoparticles (LMS) followed by wet chemical coating with Al2O3. Scanning electron microscopy (SEM) mapping of the spherical LMSA nanoparticles indicated a homogenous distribution of the constituent atoms. Small‐angle X‐ray scattering (SAXS) measurements revealed that a prominent population of the nanoparticles show a center‐to‐center spacing of 7 nm. This is resulting in a large surface area accessible for the migration of Li‐ions and efficient charge storage, leading to improved electrochemical performance as a supercapattery electrode. X‐ray diffraction (XRD) and solid‐state nuclear magnetic resonance spectroscopy (SS NMR) studies portrayed the orthorhombic (Pmn21) crystalline phase of the LMSA and LMS materials which provides a good migratory pathway for the Li‐ions. The nanocomposite showed a high rate performance as a positive electrode in an aqueous supercapattery assembled with activated carbon as the negative electrode. The hybrid cell delivered a maximum specific capacitance of 141.5 F g−1 and a maximum specific power of 4020.8 W kg−1 with good cyclic stability and capacitance retention of 93.6 % after 100 cycles. These results the promising potential of the Li2MnSiO4/Al2O3 nanocomposite as candidate for advanced supercapatteries.
Selective Oxidation of n‐Butane over Vanadium‐Phosphorus Oxide: Oxygen Activation and Dynamics
Authors: Schulz Christian , Kraehnert Ralph , Rosowski Frank , Frank Benjamin 
Published: October 2018

AbstractThe complex microkinetics of the selective oxidation of n‐butane to maleic anhydride (MAN) over vanadyl pyrophosphate‐based (VPP) catalysts has been widely investigated so far, however, they are still under debate. We present novel results of kinetic analyses and isotope labeling to shed light on the activation of gas‐phase oxygen and the dynamics of oxygen species on the catalyst surface and in the bulk. We suggest the existence of at least two catalytically relevant surface oxygen species responsible for selective and unselective activation of n‐butane, which are formed by adsorption and consecutive dissociation of O2 at the active site. The formation of selective [O] from unselective [O2] is likely promoted by co‐fed H2O, which increases the MAN selectivity. Regarding the VPP bulk serving as a reservoir for active [O] species it is concluded that the dynamic exchange is limited to the amorphous surface layer forming under reaction conditions, whereas the crystalline bulk is not involved into the reaction. Labelling studies are heavily influenced by vital 16O/18O scrambling of MAN isotopes with the reaction product H2O.

Published: October 2018

AbstractTransition metal hydroxides have attracted considerable attention as promising electrode materials in electrochemical energy storage. In this work, we first used a facile and green approach to synthesize Ni4Yb(OH)10NO3 ⋅ 3H2O nanosheets, which are thin‐layer hexagonal structures. Additionally, this method can be developed to synthesize other lanthanide‐doped Ni(OH)2 materials. When used as electrode materials, these nanosheets exhibited excellent electrochemical energy storage performance and good cycling stability. For example, the Ni4Yb(OH)10NO3 ⋅ 3H2O nanosheet electrode showed a specific capacitance of 1482.1 F g−1 at 1 A g−1, while maintaining great cycling stability (a capacity retention of 71.8 % after 2000 cycles at a current density of 1 A g−1).

Published: October 2018

AbstractIn this work, the surface plasmon resonance effect of metallic Ag, surface oxygen vacancies (SOVs), and Bi2MoO6 (BMO) material were rationally combined to construct new oxygen‐vacancy‐rich Ag/Bi2MoO6 (A/BMO‐SOVs) photocatalysts. Their synergistic effect on the photocatalytic degradation of phenol and 4‐nitrophenol under visible‐light irradiation (λ≥420 nm) was also investigated. TEM, EPR, and Raman spectra demonstrate the co‐existence of metallic Ag nanoparticles, surface oxygen vacancies, and Bi2MoO6 due to a controlled calcination process. The experimental results disclose that the 2 %A/BMO‐SOVs‐375 sample exhibited the highest photocatalytic activity for the degradation of both phenol and 4‐nitrophenol under visible‐light irradiation, achieving nearly 100 and 80 % removal efficiency, respectively, and demonstrated the apparent reaction rate constants (kapp) 183 and 26.5 times, respectively, higher than that of pure Bi2MoO6. The remarkable photodegradation performance of A/BMO‐SOVs for organic substances is attributed to the synergistic effect between the surface oxygen vacancies, metallic Ag nanoparticles, and Bi2MoO6, which not only improves the visible‐light response ability, but also facilitates charge separation. Thus, this work provides an effective strategy for the design and fabrication of highly efficient photocatalysts through integrating surface oxygen vacancies and the surface plasmon resonance effect of nanoparticles, which has the potential for both water treatment and air purification.
Magnetic Shielding, Aromaticity, Antiaromaticity and Bonding in the Low‐Lying Electronic States of S2N2
Authors: Karadakov Peter B. , Al‐Yassiri Muntadar A. H. , Cooper David L. 
Published: October 2018

AbstractAromaticity, antiaromaticity and chemical bonding in the ground (S0), first singlet excited (S1) and lowest triplet (T1) electronic states of disulfur dinitride, S2N2, were investigated by analysing the isotropic magnetic shielding, σiso(r), in the space surrounding the molecule for each electronic state. The σiso(r) values were calculated by state‐optimized CASSCF/cc‐pVTZ wave functions with 22 electrons in 16 orbitals constructed from gauge‐including atomic orbitals (GIAOs). The S1 and T1 electronic states were confirmed as 11Au and 13B3u, respectively, through linear response CC3/aug‐cc‐pVTZ calculations of the vertical excitation energies for eight singlet (S1–S8) and eight triplet (T1–T8) electronic states. The aromaticities of S0, S1 and T1 were also assessed using additional magnetic criteria including nucleus‐independent chemical shifts (NICS) and magnetic susceptibilities calculated at several levels of theory, the highest of which were CCSDT‐GIAO/cc‐pVTZ for S0 and CASSCF(22,16)‐GIAO/aug‐cc‐pVQZ for S1 and T1. The results strongly suggest that: 1) the S0 electronic ground state of S2N2 is aromatic but less so than the electronic ground state of benzene; 2) S1 is profoundly antiaromatic, to an extent that removes any bonding interactions that would keep the atoms together; and 3) T1 is also antiaromatic, but its antiaromaticity is more moderate and similar to that observed in the electronic ground state of square cyclobutadiene. S2N2 is the first example of an inorganic ring for which theory predicts substantial changes in aromaticity upon vertical transition from the ground state to the first singlet excited or lowest triplet electronic states.
N‐Heterocycle‐Stabilized Iodanes: From Structure to Reactivity
Authors: Boelke Andreas , Lork Enno , Nachtsheim Boris J. 
Published: October 2018

AbstractPseudocyclic aryl‐λ3‐iodanes are superior reagents for a variety of oxidative transformations due to a well‐balanced relation between stability, solubility and reactivity. Their properties are substantially influenced by a dative interaction between a Lewis base, in general the oxygen atom of a carboxylic acid or an amide, and the central hypervalent iodine atom. This work presents the first systematic investigation of pseudocyclic N‐heterocycle‐stabilized iodanes (NHIs). The synthesis of these throughout shelf‐stable solids is robust and can be achieved on a large scale. Their reactivity is highly tunable, depending on the stabilizing heterocycle. Solid state structures of selected derivatives are reported and their reactivity in a model oxygen transfer reaction is compared. Further derivatization reactions to N‐heterocycle‐stabilized pseudocyclic diaryliodonium salts and cyclic iodoso species are presented as well.

Published: October 2018

AbstractAn efficient carbonylative coupling reaction of two equivalents of 1,3‐butadiene, yielding aryl nona‐3,8‐dienoate esters, is performed with phenols as nucleophile, and promoted by palladium‐based catalysts. Optimization study reveals the key role of benzoic acid as a cocatalyst. The suggested catalyst combination enables the conversion of a wide scope of variously substituted phenols into corresponding esters with a high yield. Further tests were performed with diphenols, naturally‐occurring phenols and an industrial grade Kraft lignin, thus, indicating the scope of this reaction for transforming industrially relevant polyphenolic structures.

AbstractBackgroundThe relationship between physiological stress measures and body composition or behavioral problems in older children remains controversial, and data in young children are lacking. The aim of the study was to investigate this relationship in predominantly healthy preschool children.MethodPhysiological stress measures were assessed using diurnal salivary alpha‐amylase (sAA) and salivary cortisol, nail cortisol and parasympathetic activation (PNS) by overnight heart rate variability, and body composition (body mass index, skinfold thickness) and behavior problems (using the Strengths and Difficulties Questionnaire) in 324 children aged 2–6 years of the SPLASHY study.ResultsParasympathetic nervous system was inversely related to body fat, to emotional, and to peer problems. Diurnal sAA was related to hyperactivity problems and moderated the relationship of cortisol and hyperactivity problems. Cortisol was not related to any other health problems.DiscussionThe relationship of PNS with body composition and behavioral problems might highlight the protective role of the parasympathetic system early in life.

Plasma cells: The programming of an antibody‐secreting machine
Authors: Tellier Julie , Nutt Stephen L 
Published: October 2018

AbstractAntibodies are an essential component of our immune system, underpinning the effectiveness of both the primary immune response to microbial pathogens and the protective and long‐lived immunity against re‐challenge. All antibodies are produced by relatively rare populations of plasmablasts and plasma cells, collectively termed antibody‐secreting cells (ASCs). It is now apparent that ASCs are unique in the body in terms of their gene expression program and metabolic pathways that enable these cells to have an extraordinary rate of immunoglobulin gene transcription, translation, assembly and secretion. In this review we will discuss the cellular, metabolic and molecular specialization that allows ASCs to maintain such high rates of antibody production, in some cases for the life of the individual. Throughout the review we will link these exquisite cellular and molecular adaptations to the major regulators of ASC gene expression, in an attempt to define how the ASC phenotype and function is genetically programmed.

Abstract

We present a blue mussel exposure system where the fate of microplastics (polystyrene beads) is tracked during exposure and depuration phases. This enabled the establishment of a complete mass balance. Quantification of beads in mussels was done with a novel enzymatic digestion protocol. We found a similar relative distribution of beads for 2 environmentally realistic concentrations (5 and 100 beads L−1) and no substantial egestion of particles within 2 h of depuration.

Abstract
A complete mass balance of microplastic beads in a blue mussel exposure system was established by quantifying beads in 4 compartments: the exposure water, the mussel after exposure, the depuration water, and the mussel after depuration. MP = microplastic.

Published: October 2018

AbstractBackgroundGlobally, population‐wide sodium reduction strategies have been adopted and implemented to address the adverse health effects of excess dietary sodium. However, in Canada, minimal coordinated action by governments has occurred, including interventions aimed at food service operations in hospitals and long‐term care (LTC) centers. The objective of this study was to investigate actions, attitudes, barriers, and facilitators related to sodium reduction in these institutions.MethodologyA cross‐sectional survey was administered to food service administrators working in hospitals and LTC facilities in Ontario. Responses from key informants from 27 institutions, representing 9,823 patient/resident beds were included.ResultsOverall, 63.0% of institutions had an established sodium target (900–4,000 mg/day). The reported sodium level on “regular” menus was 2,845 ± 1,025 mg/day. Sixty‐three percent believed it was important to reduce sodium on inpatient/resident menus. Top facilitators reported for sodium reduction included group purchasing organizations identifying lower sodium foods (85.2%), increased availability of pre‐packaged lower sodium products (77.8%), government prioritizing and providing support and resources (74.1%), and improved taste of lower sodium foods (74.1%). Only 37.0% believed that patient/resident satisfaction would decrease with sodium reduction. Sodium reduction practices were variable among food service operations.ConclusionsThese data support the need for consistent and coordinated policies to facilitate sodium reduction in hospitals and long‐term care settings and for multi‐sectorial government, industry, and institutional support to ensure success.
Experience from TBM excavation obtained in the Follo Line Project
Authors: Gollegger Johannes 
Published: October 2018

AbstractIn some projects the selection of TBM is straight forward, but in others all boundary conditions have to be carefully evaluated in order to make the most suitable choice. For underground projects the actual ground conditions remain to certain degree always unknown, regardless of the performed ground investigations. This means specific parameters, which may have significant impact on the project success, might be over‐ or underestimated. Such parameters could be different rock mass properties as well as water ingress. This paper discusses some relevant parameters for TBM selection in hard rock environment, mainly based on the experience gained in the Follo Line Project in Norway. Four double shield TBMs with excavation diameter of 9.96 m are drilling through various kinds of gneisses with banding and lenses of amphibolite and pegmatite. More than 75 % of a total of 36 km have already been excavated with several kilometres of pre‐excavation grouting for reduction of water ingress. Furthermore, potential improvements for TBMs will be proposed in order to make TBMs even more successful.
Selection of a suitable TBM for soft ground tunnelling
Authors: Edelhoff Dennis , Humme Eva 
Published: October 2018

AbstractFor tunnelling in loose rock, where active and continuous support of the face is required, the application areas of mix/hydro and EPB shield machines are increasingly overlapping to such a degree that the use of both types of machine is possible both in the fine‐grain range and in coarse‐grained loose rock. Since the prevailing soil conditions are rarely homogeneous, but rather characterised by alternating sequence, the planning process is of decisive importance. However, it is not possible to select machines solely based on soil conditions or geotechnical parameters. The supplementary assessment areas include the machine‐ and process‐engineering, system‐immanent special features, e.g. management of bricks/blocks, transfer of supporting pressure and maintenance, interaction of TVM building ground regarding wear and sticking, utilization of the overburden as well as evaluation of the spoil quality. This article describes the main aspects of the decision‐making process for suitable machine and tunnelling technology and summarizes the advantages and disadvantages.
Validation of longitudinal displacement profiles by measurement at the Brenner Base Tunnel
Authors: Schneider‐Muntau Barbara , Reinhold Chris , Cordes Tobias , Bathaeian Iman , Bergmeister Konrad 
Published: October 2018

AbstractLongitudinal displacement profiles describe the displacement history during tunnel excavation, including that occurring ahead of the tunnel face. These deformations have an influence on the structural design of tunnel support. Theoretical approaches are used to estimate these deformations. However, as the approaches are based on assumptions, they should be applied with caution, particularly in case of deep tunnels. Therefore, experimentally determined longitudinal displacement profiles provide a valuable data basis for validation of the approaches. This study compares 40 m long horizontal chain inclinometer measurements in two lithologies in the exploration tunnel of the Brenner Base Tunnel with theoretically calculated profiles. The chain inclinometers were installed above the tunnel before the start of tunnelling. A measured radial displacement profile was created for each round, the statistical mean value curve was calculated and finally compared with the theoretical approaches. The measurement results show good qualitative agreement ahead of the tunnel face.
