AbstractThe Immobilization of homogeneous metal catalysts onto the solid surface is an important challenge in the field of catalysis because these types of catalysts provide the homogeneous nature as well as reusability of catalysts. In this report, novel Palladium ion containing ionic liquid immobilized onto graphene oxide (Pd@GOIL) and characterized using various analytical techniques like FT‐IR, XPS, TGA, SEM, TEM, BET and EXAFS analysis. This synthesized material acts as a highly efficient catalyst for the alkoxycarbonylation, aminocarbonylation and phenoxycarbonylation reactions from easily available aryl iodides. Effect of various reaction parameters like CO pressure, base, solvent, the effect of time and temperature using Pd@GOIL catalyst were examined. This catalyst also tolerates the wide variety of substrates with the effective electronic factor. Specifically, this catalyst shows excellent catalytic performance towards the esterification and amidation without the need of any ligands, co‐catalysts and additives. Additionally, the catalyst shows superior recyclability up to eight recycle runs without discernible activity and selectivity deterioration.

Authors: Wagner Alexa‐Sibylla , Kilincsoy Ümit , Vink Peter 
Published: March 2018

AbstractEvolving multimodal mobility needs influences established human–product relationships and requires a deeper insight into color preferences for car interiors. Hence, a study was conducted in which 204 members of a web contest created 1,265 designs. After a peer‐evaluation process, 53 most‐appreciated and 34 least‐preferred interior color compositions were identified and compared to identify patterns in color choices. Besides, visual lightweight design by layering of large interior components such as the seat, a modest use of color and patterns accompanied by repetition and the framing of the entire interior to create a feeling of spaciousness were found. Additionally, differences in the type of color between most and least favored color designs were found. Brown and beige occur more frequently among the top‐ than the worst‐rated designs. Larger surfaces are favored in lighter hues and smaller components in darker hues.

Templated DNA Cross‐Linking: Towards a Non‐Invasive Singlet‐Oxygen‐Based Triggering Method
Authors: De Laet Nathalie , Llamas Eva M. , Madder Annemieke 
Published: March 2018

AbstractSinglet‐oxygen‐induced DNA interstrand cross‐linking was achieved at intracellularly relevant concentrations using a templated reaction setup. The target oligonucleotide serves as a template ensuring proximity between a “furan warhead”‐containing probe and an activator probe containing a photosensitizer able to generate 1O2. Visible light irradiation of this self‐activating assembly allows us to achieve highly selective interstrand crosslinking at concentration levels relevant for intracellular applications.

Investigation of statistical behaviour of electrical breakdown voltage distribution for nitrogen‐filled diode at 13.3 mbar pressure
Authors: Živanović Emilija N. , Maluckov Čedomir A. 
Published: March 2018

The results of statistical analysis of the electrical breakdown voltage distribution in nitrogen are presented in this paper. For obtaining the experimental results, a nitrogen‐filled diode at 13.3 mbar pressure was used. The dynamic method was used for estimating the static breakdown voltage. One‐hundred voltage measurements were carried out for each value of the increase in the voltage rate from 1 up to 10 V/s. Wilcoxon test was used for checking the measurements' randomness for each rate. The experimental distribution functions are fitted with the three‐parameter Weibull distribution function. The coefficients of the Weibull distribution are also estimated.

BackgroundEndoscopic ultrasound‐guided fine‐needle aspiration (EUS‐FNA) has become increasingly popular for the diagnosis and staging of gastrointestinal diseases and peri‐gastrointestinal lesions. The application of FNA/Brush has dramatically expanded the clinical utility of EUS.Aims and objectiveTo evaluate the diagnostic accuracy, study the spectrum of lesions encountered in EUS‐FNAC/brush cytology of gastrointestinal and peri‐gastrointestinal lesions.Materials and methodsTotal of 124 patients during the period from August 2015 to November 2016 was included in the study. Routine staining was done.ResultsA total of 124 cases were studied with 86% (107 cases) being satisfactory for evaluation. M:F ratio was 1:1.03, mean age of 50.5 years. The most common site was common bile duct (CBD) (37%) followed by lymph node (21%), pancreas (17.7%), esophagus (17%), stomach (3.5%), liver (1.8%), gallbladder (1%), and spleen (1%). In total, 53.4% lesions were benign, in 6.5% atypical cells were seen, 12.1% were suspicious for malignancy, and 28% cases were positive for malignancy. Follow‐up was available in 102 cases with cyto‐histopathological concordance rate of 90%.ConclusionEUS‐FNA/Brush is a reliable, sensitive, specific and minimally invasive way to establish a diagnosis. It can be utilized as a pre‐operative procedure for the management of many intra‐abdominal lesions and prevent unnecessary invasive procedures.

Published: March 2018

AbstractDiet regulation behavior can mediate the consequences of imbalanced diets for animal well‐being, particularly for captive species that have little dietary choice. Dasyurids (carnivorous marsupials) are of conservation concern in Australia, and many species are in captive breeding programmes. However, their nutrient targets and dietary regulation behaviors are poorly understood, a limitation that may decrease the breeding success and well‐being of captive animals. We tested how dietary protein content influenced the intake and utilization of nutrients, physical activity, and body mass of fat‐tailed dunnarts Sminthopsis crassicaudata. Twelve adult dunnarts from six sibling pairs (one female and one male per pair) were provided ad libitum access to three diets in a repeated measures design: cat food, cat food supplemented with raw lean beef (1:1), and cat food supplemented with cooked lean beef (1:1). Food intake, activity level, and fecal output were measured daily. Dunnarts significantly decreased food intake, increased protein digestion, and physical activity, but body mass was unchanged when on the high‐protein diet compared to the normal cat food diet. These observations suggest a capacity of dunnarts to maintain constant body mass using a dynamic balance of feeding, digestion, and activity. We also found a significant effect of family, with differences between families as large as the difference between the diet treatments, suggesting a genetic component to diet selection. The nutrient regulation responses of dunnarts to high‐protein diets and the strong family effects provide important messages for the management of populations of small carnivores, including the aspects of dietary manipulation and conservation of genetic diversity.

Published: March 2018

SummaryObjectiveNavigated transcranial magnetic stimulation (nTMS) is becoming increasingly popular in noninvasive preoperative language mapping, as its results correlate well enough with those obtained by direct cortical stimulation (DCS) during awake surgery in adult patients with tumor. Reports in the context of epilepsy surgery or extraoperative DCS in adults are, however, sparse, and validation of nTMS with DCS in children is lacking. Furthermore, little is known about the risk of inducing epileptic seizures with nTMS in pediatric epilepsy patients. We provide the largest validation study to date in an epilepsy surgery population.MethodsWe compared language mapping with nTMS and extraoperative DCS in 20 epilepsy surgery patients (age range 9‐32 years; 14 children and adolescents).ResultsIn comparison with DCS, sensitivity of nTMS was 68%, specificity 76%, positive predictive value 27%, and negative predictive value 95%. Age, location of ictal‐onset zone near or within DCS‐mapped language areas or severity of cognitive deficits had no significant effect on these values. None of our patients had seizures during nTMS.SignificanceOur study suggests that nTMS language mapping is clinically useful and safe in epilepsy surgery patients, including school‐aged children and patients with extensive cognitive dysfunction. Similar to in tumor surgery, mapping results in the frontal region are most reliable. False negative findings may be slightly more likely in epilepsy than in tumor surgery patients. Mapping results should always be verified by other methods in individual patients.
A rational H∞‐norm–based approach for the optimal design of seismically excited reinforced concrete frames
Authors: Venini P. , Ceresa P. 
Published: March 2018

SummaryA rational approach is presented for minimizing the dynamic response of reinforced concrete framed structures forced by a seismic base acceleration. Reference is made to EC8 regulations, but the presented approach may in principle be applied to structures ruled by any regulation code. Governing equations are set in the frequency domain (and not in the periods domain as usual) so as to enable the adoption of sound approaches for analysis and design of dynamic structures that are typical of automatics. Among these, a novel usage of the H∞‐norm concept is proposed that determines a rational design approach capable to minimize the structural response with reference to any quantity of engineering interest, eg, the overall compliance and the displacement of a specific point or the interstorey drift. A numerical investigation on a 6‐storey 3‐bay frame is performed, and relevant analysis and design results are presented in much detail to validate the theoretical framework.
Triassic alkaline magmatism and mineralization in the Xiong'ershan area, East Qinling, China

Published: March 2018

The Qinling orogenic belt is a complex subduction–accretion–collision orogen that welded the North China Craton and the Yangtze Craton during the final continental collision in the Triassic. The Xiong'ershan area, located in east Qinling, exposes a typical Triassic syenite pluton and several contemporaneous Mo, Au, and Cu deposits. The aegirine–augite syenites and syenites from the Mogou pluton are characterized by alkalic to peralkalic (total alkali Na2O + K2O = 13.95–14.63 wt.%, CaO = 0.06–2.87 wt.%), and shoshonitic features (K2O = 11.86–14.34 wt.%). Zircon LA–ICP–MS U–Pb dating of the aegirine–augite syenite and syenite yield emplacement ages of 232.5 ± 0.6 and 221.8 ± 0.7 Ma, indicating multiple pulses of magmatism. Evidence from zircon Hf isotopes; occurrence of mafic microgranular enclaves; heterogeneous peralkaline composition; and wide ranges of MgO, Ni, and other trace elements suggest that the parental magma was mainly sourced from partial melting of Archean to Paleoproterozoic crustal sources, mixed with juvenile mantle‐derived mafic magmas. The Mogou pluton was probably emplaced in the tectonic transition from syn‐collision to post‐collision settings and accompanying slab break‐off process, from the commencement of collision at approximately 245 Ma and post‐collisional extension at approximately 210 Ma. Gold, molybdenum, and copper deposits formed during the interval of 255–208 Ma, and the close temporal and spatial relationship between these Triassic polymetallic deposits and the Mogou alkaline pluton invokes a genetic linkage. The heat source for magmatism and related metallogeny is correlated to a hot upwelling asthenospheric mantle that caused partial melting of the Archean to Paleoproterozoic crustal basement, resulting in magma mixing between the two end‐members.
Petrogenesis of two stages of Cretaceous granites in south‐west Fujian Province: Implications for the tectonic transition of South‐east China

Published: March 2018

Zircon U–Pb data indicate that Cretaceous magmatism in Fujian Province occurred in two pulses, with the Xiyang, Yangshan, Wuci, Dehua, Juzhou, and Xiandu plutons emplaced between 147 ± 1 and 126 ± 1 Ma and the Hutou and Guangqiao plutons emplaced at 109 ± 1 Ma. Combining these previously published ages with the new data obtained during this study indicates that the magmatism in the study area occurred in two distinct stages at 145–125 and 110–100 Ma, both have I‐type characteristics. The earlier I‐type granites are characterized by relatively high concentrations of SiO2 (mean = 75.73 wt.%) and low concentrations of MgO (mean of 0.21 wt.%) and are metaluminous to weakly peraluminous (mean A/CNK = 1.03). They contain relatively high total rare‐earth element (ΣREE) concentrations (mean of 139.3 ppm) with well‐developed Eu anomalies and are relatively enriched in the large‐ion lithophile elements (LILE) and the light REE (LREE) but depleted in Ba, Sr, P, Ti, Nb, and Ta. In contrast, the younger I‐type granites contain lower concentrations of SiO2 (mean of 67.63 wt.%), higher concentrations of MgO (mean of 1.47 wt.%), and are metaluminous to weakly peraluminous (mean A/CNK = 0.96). They also have moderate REE values (mean of 150.26 ppm) without significant Eu anomalies and are relatively enriched in LREE, Rb, Th, U, K, Sr, and Pb and depleted in Nb, Ta, P, Ti, Y, and Yb. The two‐stage Nd model ages (T2DM) of Cretaceous granites are 1.46 to 1.88 Ga (mean of 1.57 Ga) and 1.16–1.60 Ga (mean of 1.36 Ga), respectively. The two‐stage Hf model ages (T2DM) of Cretaceous granites are 1.19–1.82 Ga (mean of 1.54 Ga) and 0.46–1.20 Ga (mean of 0.91 Ga), respectively. It is likely that the earlier I‐type granites were derived from magmas generated by the partial melting of Mesoproterozoic metabasaltic material, whereas the later I‐type granites were derived from magmas generated by partial melting of a mixed lithology containing Mesoproterozoic to Neoproterozoic metabasaltic to metatonalitic rocks that were underplated by medium‐ to high‐K basaltic magmas. A geological comparison between south‐western Fujian Province and adjacent areas indicates that the earlier I‐type granites were emplaced in a compressional environment associated with the subduction of the paleo‐Pacific Plate at 145–125 Ma. In contrast, the later I‐type plutons are associated with intraplate extension accompanied by the post‐subduction slab roll‐back of the paleo‐Pacific Plate. The two magmatic stages represent a transition from compressional to intraplate extensional tectonics between 125 and 110 Ma, with mantle‐derived material playing a crucial role in the formation of the I‐type granites.
Brain dynamics in ASD during movie‐watching show idiosyncratic functional integration and segregation

Published: March 2018

AbstractTo refine our understanding of autism spectrum disorders (ASD), studies of the brain in dynamic, multimodal and ecological experimental settings are required. One way to achieve this is to compare the neural responses of ASD and typically developing (TD) individuals when viewing a naturalistic movie, but the temporal complexity of the stimulus hampers this task, and the presence of intrinsic functional connectivity (FC) may overshadow movie‐driven fluctuations. Here, we detected inter‐subject functional correlation (ISFC) transients to disentangle movie‐induced functional changes from underlying resting‐state activity while probing FC dynamically. When considering the number of significant ISFC excursions triggered by the movie across the brain, connections between remote functional modules were more heterogeneously engaged in the ASD population. Dynamically tracking the temporal profiles of those ISFC changes and tying them to specific movie subparts, this idiosyncrasy in ASD responses was then shown to involve functional integration and segregation mechanisms such as response inhibition, background suppression, or multisensory integration, while low‐level visual processing was spared. Through the application of a new framework for the study of dynamic experimental paradigms, our results reveal a temporally localized idiosyncrasy in ASD responses, specific to short‐lived episodes of long‐range functional interplays.

AbstractBACKGROUNDA series of monoacrylate modified adsorption resins from reactive mixtures with different amounts and types of monoacrylate have been synthesized by an oil/water (O/W) suspension polymerization technique and utilized to remove fermentation inhibitors and pigments from rice straw hydrolysate for the first time. The modified resin was characterized by Fourier transform infrared spectroscopy (FT‐IR), scanning electron microscopy (SEM) and N2 adsorption–desorption isotherms. Batch experiments were carried out to determine the adsorption performance of the modified resin for fermentation inhibitors. Regeneration and reusability experiments were performed to evaluate the economic value.RESULTSThe modified resin with 80% glycidyl methacrylate (GMA) feed and epoxy group showed optimal selectivity of fermentation inhibitors from rice straw hydrolysate. The adsorption capacities of acid soluble lignin (ASL), formic acid, acetic acid, levulinic acid, 5‐hydroxymethylfurfural (5‐HMF) and furfural onto 80% GMA modified resin were enhanced by 45%, 156%, 86%, 79%, 131%, 52%, respectively. Furthermore, the decolorization rate was improved by 12% over unmodified styrene‐divinylbenzene (St‐DVB) adsorption resin with approximately 5% sugar loss.CONCLUSIONThis work not only provides a potential adsorbent for the removal of fermentation inhibitors from rice straw hydrolysate, but also provides guidance for choosing and modifying the adsorbent to detoxify lignocellulose hydrolysate. © 2018 Society of Chemical Industry

Published: March 2018

AbstractA method is proposed to predict ions' collision cross‐sectional area from properties that are already evaluated in standard quantum chemistry software. Computed molecular isodensity surface areas recover the predictions of existing projection approximations. Computed solvent cavity areas give comparable accuracy. This provides a simplified workflow for assigning ion‐mobility mass spectra.

Published: March 2018

AbstractBACKGROUNDThe pharmaceutical industry has boosted gelatin consumption worldwide. This is supported by the availability of cost‐effective gelatin production from porcine by‐products. However, cross‐contamination of gelatin materials, where porcine gelatin was unintentionally included in the other animal sources of gelatin, has caused significant concerns about halal authenticity. The real‐time polymerase chain reaction (PCR) has enabled a highly specific and sensitive animal species detection method in various food products. Hence, such a technique was employed in the present study to detect and quantify porcine DNA in gelatin using a molecular beacon probe, with differences in performance between mitochondrial (cytochrome b gene) and chromosomal DNA‐(MPRE42 repetitive element) based porcine‐specific PCR assays being compared.RESULTSA higher sensitivity was observed in chromosomal DNA (MPRE‐PCR assay), where this assay allows the detection of gelatin DNA at amounts as as low as 1 pg, whereas mitochondrial DNA (CBH‐PCR assay) can only detect at levels down to 10 pg of gelatin DNA. When an analysis with commercial gelatin and gelatin capsule samples was conducted, the same result was observed, with a significantly more sensitive detection being provided by the repetitive element of chromosomal DNA.CONCLUSIONThe present study has established highly sensitive DNA‐based porcine detection systems derived from chromosomal DNA that are feasible for highly processed products such as gelatin and gelatin capsules containing a minute amount of DNA. This sensitive detection method can also be implemented to assist the halal authentication process of various food products available on the market. © 2018 Society of Chemical Industry
