Beyond Coincidence: The Reasoning Process Underlying Utility Proportional Beliefs Process
Authors: Tobias Nauerz Christian 
Published: July 2018

Abstract
We provide insights into (Bach, Christian W., and Andrés Perea’s. 2014. “Utility Proportional Beliefs.” International Journal of Game Theory: 1–22) concept of utility proportional beliefs and characterize its underlying reasoning process in normal-form games. Our analysis suggests that assumptions on the sensitivity to utilities influence players’ reasoning process and therefore the computations necessary to obtain a belief about the opponent. Under the assumption that more complex computations take longer to complete, we develop additional hypotheses about the players’ reaction times. These additional hypotheses allow for more rigorous testing of the concept than pure accordance with predictions. Using (Nauerz, Christian T., Marion Collewet, and Frauke Meyer. 2015. “Explaining Beliefs in Strictly Competitive One-shot Games.” Working Paper) data set we confirm our hypotheses about players’ reaction times, strengthening our trust in the concept.

AbstractBackgroundThis case-control study investigated an association between breast milk jaundice (BMJ) and infants’ gut microbiome. The study included determination of the diversity of the gut microbiome and identification of bacterial genera associated with BMJ.MethodsThe study population consisted of 12 infants with BMJ and 22 breastfed infants without jaundice (control). DNA collected from feces was analyzed by PCR amplification and 1% agarose gel electrophoresis, and then sequenced with a MiSeq system. Relative quantification bioinformatics was employed to analyze the DNA sequencing data. An Illumina high-throughput sequencing platform was used to analyze 16S rRNA variable (V) regions V3 and V4 in stool samples.ResultsIn the control group, the proportion ofEscherichia/Shigella(genus level) in the gut microbiome (64.67%) was significantly higher than that of the BMJ group. However, the prevalence ofBifidobacteriumorEnterococcusin the gut microbiome of the two groups was similar. The Simpson index indicated that the diversity of the bacterial population in the BMJ infants was significantly narrower than in the normal infants.ConclusionThe prevalence ofEscherichia/Shigellain the gut of breastfed infants is important for lowering BMJ development.

AbstractThis study aimed to compare in vitro cell cytotoxicity and antiproliferative potency of three standardized ethanolic extracts (5mg GAE/mL sample) from quince flower petals, leaves and fruit pellet on four cell lines (L-929, and HepG2, Caco-2 and BT-20 respectively). Comparative analytical qualitative studies (HPTLC) indicated that if quince leaf extracts (Col40) mainly contain quercetin and kaempferol derivates, the flower petal extracts (Cof40) contain caffeoylquinic acid derivates, while the fruit pellet extracts (Cop40) are comprised of quercetin and caffeoylquinic acid derivates. Pharmacological studies demonstrated the lack of toxicity of test extracts; the most important antiproliferative effects were observed on the hepatic cancer cell line HepG2 (up to 75%, 53% and 70% inhibition in the case of Col40, Cof40 and Cop40 test extracts), followed by the colon cancer cell line Caco-2 (up to 69%, 77% and 40% inhibition) and breast cancer cell line BT-20 (up to 54%, 61% and 19% inhibition). The docking simulations on hyperoside, isoquercitrin, astragalin, and quercetin and kaempferol compared to the synthetic co-crystallized LI0 A1000 ligand (a strong inhibitor of anti-apoptotic protein Bcl-2) indicated astragalin as the most feasible protein inhibitor, but quercetin and kaempferol respected all the parameters involved in the Lipinski rule, making them the most promising antiproliferative candidates.

Published: July 2018

Abstract
Electrodeposition and stripping of Zn, Mn and Ni metals and their alloys were investigated in an aqueous sulfate solution. The effect of coating processes and its impact on the substrate were evaluated by investigating the prepared alloys with X-ray diffraction analysis, scanning electron microscopy and atomic absorption spectroscopy. The electrodeposition mechanism of the Zn-Ni-Mn alloy was found to be an anomalous type. The high corrosion resistance of the Zn-Ni-Mn alloy, as well as its preferable surface appearance, has been ascertained compared with the electrodeposited Zn-Ni alloy under homogeneous conditions. It was found that Mn can be codeposited with Ni or with Ni and Zn understudied conditions where it does not deposit in its pure form. During electrodeposition of manganese alone or manganese alloys, a dark brown deposit was formed on the counter platinum electrode surface as a result of oxidation to manganese dioxide.

Abstract
2-(4-Bromophenyl)-1-(3-chloro-2-methylphenyl)- 4,5-diphenyl-1H-imidazole (1) and 1-(3-chloro-2-methylphenyl)-2-(4-chlorophenyl)-4,5-diphenyl-1H-imidazole (2) were synthesized by one-pot four-component reactions. These compounds crystallize in the monoclinic crystal system with the space group P21/n. The crystal structures were solved by direct methods and refined by a full matrix least squares procedure to a final R value of 0.0572 (1) and 0.0588 (2) for 2748 and 2278 observed reflections, respectively. Molecular docking studies were implemented to understand the inhibitory activity of related compounds against glucosamine 6-phosphate (GlcN-6-P) synthase, the target protein for the antimicrobial agents.

Published: July 2018

Abstract
The efficiency of the growth and properties of zinc oxide (ZnO) nanoparticles (ZnO-NPs) on pulp fibers was investigated. ZnO-NPs were grown on pulp fiber surface via an in situ chemosynthesis method at different concentrations. The modified pulp fibers were characterized by different analytical tools including field-emission scanning electron microscopy (FE-SEM), Fourier-transform infrared (FTIR) spectroscopy, X-ray power diffraction (XRD) and thermogravimetric (TG) analysis. Ultraviolet (UV) absorption and antibacterial properties of the paper made from treated and untreated pulp fibers were analyzed. The results revealed that the rod-like ZnO-NPs were successfully grown onto the fiber surfaces without aggregation. As the precursor concentration increased from 0.01 to 0.07 mol l−1, the ZnO loading on the fibers increased from 4.2 to 23.4%, respectively. Compared to the untreated fibers, paper made from ZnO-treated fibers had a better UV absorption ability and antimicrobial effect against Escherichia coli and Staphylococcus aureus. However, the ZnO-treated pulp fiber reduced the zero span tensile index of the paper.

Abstract

Viburnum macrocephalum f. keteleeri, not well explored in the pharmaceutical field, is a tall deciduous shrub and commonly used as folk medicines for the treatment of type 2 diabetes (T2D). In this study, the dried branches of V. macrocephalum f. keteleeri were extracted with 95% ethanol and the extract was fractionated on the basis of polarity with ethyl acetate and n-butanol. Among the different fractions, the ethyl acetate fraction exhibited the highest α-glucosidase inhibitory activity, and its bioassay-guided fractionation led to the isolation and identification of six compounds including a new 8-O-4′-neolignan glycoside (1), categorized as a rare 7-deoxy skeleton, three previously undescribed phenolic glycosides (2–4), together with two known secondary metabolites (5, 6), which were found for the first time in Viburnum. Noticeably, compound 1 had almost the same intestinal α-glucosidase inhibitory activity as the positive control acarbose.

AbstractThe application of nanoparticles in dye degradation is one of the trending arenas of research in the present day world. In this work, we report a novel route to synthesise MgO/TiO2metal oxide nanocomposite by microemulsion technique and its application in photocatalytic dye degradation. Oil in water microemulsion was prepared using Span 80 and Tween 80 as surfactants whose proportion was regulated using hydrophilic and lipophilic Balance (HLB). The obtained microemulsion was then mechanically stirred and calcined to obtain the nanocomposite. The as-prepared nanocomposites were characterized using X Ray Diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The prepared nanoparticles exhibited remarkable potential to degrade azo dye (Methyl red) under UV-Visible light irradiation. The effect of catalyst in the degradation was studied for different concentrations of dye (20, 40, 60, 80, 100 mg/L) and different loadings of the catalyst (0.4, 0.6, 0.8, 1.0, 1.2 g/L) so as to determine the optimum catalyst load. The consistency of the obtained data was compared with the first order reaction rate expression. Quasi steady state model was used in fitting the data and the kinetic constants were evaluated. Also, the degradation efficiency of MgO/TiO2nanocomposite was compared with the degradation efficiency of TiO2nanoparticles synthesized by microemulsion method.

Published: July 2018

AbstractCheese whey is a byproduct of the cheese industry and contains high concentrations of organic matter. Anaerobic digestion (AD) technology is an attractive solution to whey disposal since it allows the reduction of organic matter and simultaneously generates energy via biogas. The biological degradation of cheese whey is characterized by an unstable operation. A critical operational issue in the AD treatment of cheese whey is the tendency of rapid acidification of the waste requiring robust monitoring and control systems for reliable and efficient operation. Recent studies show that techniques based on fractal analysis of time series can be used for the indirect monitoring of critical variables of AD process (i. e., COD, VFA and methane production) for agro-industrial wastewaters. In this work, the application of the fractal analysis of pH time series obtained from an up-flow digester for cheese whey treatment is presented. The results suggest that fractal analysis can be applied to the indirect monitoring of a representative and high strength dairy wastewater. Furthermore, although the complex phenomena underlying in pH in the AD of cheese whey, the fractal analysis can unveil correlations of fractal parameters with key process variables.
Highly Effective Activated Carbons from Turkish–Kozlu Bituminous Coal by Physical and KOH Activation and Sorption Studies with Organic Vapors
Authors: Oguz Erdogan Fatma , Kopac Turkan 
Published: July 2018

Abstract
Activated carbons were produced from coal by activations applying physical and chemical (with KOH) treatments for adsorption of selected organic vapors. Physical activations were carried out at 400–900°C under N2/CO2 flow. The effects of different variables such as carbonization temperature and flow rate on the final porous texture were investigated. Chemical activation gave more effective results in terms of both porosity development and adsorption capacity. Pore characterization of carbon samples was evaluated with the observation of N2 adsorption-desorption isotherms at 77 K. The adsorption of isopropyl alcohol, acetone and ethyl alcohol on the coal derived activated carbons were determined by a volumetric technique at room temperature. The highest surface area was obtained as 1904 m2/g by KOH treatment at 800°C. The adsorption isotherm data of the selected organic vapors on carbon samples were compared with the BET, Langmuir, Freundlich, Dubinin-Radushkevich, Dubinin-Astakhov, Harkins-Jura, Henderson, Halsey and Smith adsorption models. Adsorption capacities of organic vapors for carbon samples were related with the development of surface area. Among the four chemically activated carbons produced K1_K_600, K1_K_700 and K1_K_800 showed better isopropyl alcohol and acetone adsorption than the commercial activated carbon. K1_K_700 and K1_K_800 samples showed better ethyl alcohol adsorption. Isopropyl alcohol, acetone and ethyl alcohol adsorption capacities of the obtained sample that had the maximum surface area were determined as 39.7, 44 and 43.5 %, respectively. Results indicate that activated carbons prepared with KOH at 600–800°C could be effectively used for the adsorption of organic vapors.
Interactions between type of form-focused instruction, type of morphosyntactic form, and type of language knowledge
Authors: Ghorbani Majid 
Published: July 2018

AbstractAlthough claims about the nature of EFL/ESL learners’ knowledge (i. e., implicit and/or explicit) are essential to many debates in foreign/second language development, few studies have sought to evaluate the effects of linguistic and/or contextual variables on the two knowledge types. This study, accordingly, undertook to examine the effects of different explicit and implicit types of form-focused instruction (FFI) on the acquisition of four easy and difficult forms as assessed by different implicit and explicit outcome measures. The instruments utilized to assess students’ learning were: oral elicited imitation, untimed and timed grammaticality judgment, and metalinguistic knowledge tests. A pretest and two posttests were administered to 150 novice learners immediately after FFI and again after a 4-week delay. Immediate and durable effects of FFI were found for the easy and difficult target forms on both implicit and explicit knowledge measures. Specifically, the study indicated that explicit and implicit types of FFI were significantly more beneficial for explicitly-easy and implicitly-easy language forms respectively. The findings of this study may contribute a different set of insights to our understanding of the efficacy of varying types of FFI on learners’ controlled and/or spontaneous use of easy and difficult structures at early stages of L2 development.
Collaborative dialogue: opportunities and challenges in vocabulary acquisition and retention of threshold EFL learners
Authors: Ahmadian Moussa , Tajabadi Azar 
Published: July 2018

AbstractBelonging to the interactionist perspective, the collaborative dialogue is a technique which engages learners in joint problem-solving and knowledge building. With the aim of investigating the link between this technique and vocabulary acquisition and retention, this study was conducted with 18 threshold English as a Foreign Language (EFL) learners who were randomly chosen and put in 6 groups. They were given 6 lexical-focused tasks to be completed collaboratively and their interaction was audio-recorded. The instances of lexical-based language-related episodes (LREs) were identified in the transcribed dialogues and their outcomes were coded as “correctly resolved”, “incorrectly resolved”, and “unresolved”. The frequency of the LREs was computed; it was found that the learners were able to solve the lexical problems they encountered to a very large extent. Furthermore, the analysis of LREs and the comparison of posttest and delayed posttest scores provided convincing evidence of a link between the outcomes of LREs and the learners’ vocabulary acquisition and retention, suggesting that “correctly resolved” LREs resulted in learning and retaining the target words, while “unresolved” LREs led to non-significant learning and “incorrectly resolved” LREs led to learning the wrong meaning of the vocabulary items. The findings along with the opportunities and challenges of collaborative dialogue are discussed and possible implications for language teaching are explained.

Abstract
Digital Twin technology is increasingly gaining importance for digitizing industry. Even if digital twin technology still needs fundamental research, its significance for industry has become very visible, as digital twin technology is a key success factor to professionalize Cyber-Physical Systems (CPS) applications. Industrie 4.0 as an initiative to increase industrial added value is based on establishing connectivity between CPS and to enable communication between CPS. The industrial application scenarios for Industrie 4.0 aim at vertical and horizontal lifecycle integration concepts where digital twin technology plays an important role. This contribution explains major concepts of Industrie 4.0 and derives the role of digital twin technology. Furthermore, digital twin approaches are presented and as well as the proposal to use the STEP-technology (Standard for the Exchange of Product Model Data, ISO 10303) as a fundamental basis for a comprehensive digital twin technology.
A One-Pass Approach for Slope and Slant Estimation of Tri-Script Handwritten Words

Published: July 2018

Abstract
Handwritten words can never complement printed words because the former are mostly written in either skewed or slanted form or in both. This very nature of handwriting adds a huge overhead when converting word images into machine-editable format through an optical character recognition system. Therefore, slope and slant corrections are considered as the fundamental pre-processing tasks in handwritten word recognition. For solving this, researchers have followed a two-pass approach where the slope of the word is corrected first and then slant correction is carried out subsequently, thus making the system computationally expensive. To address this issue, we propose a novel one-pass method, based on fitting an oblique ellipse over the word images, to estimate both the slope and slant angles of the same. Furthermore, we have developed three databases considering word images of three popular scripts used in India, namely Bangla, Devanagari, and Roman, along with ground truth information. The experimental results revealed the effectiveness of the proposed method over some state-of-the-art methods used for the aforementioned problem.
Estimation of Signal-to-Cross Talk Ratio of Stimulated-Raman-Scattering-Induced Cross Talk in Wavelength-Division-Multiplexing-Based Radio-over-Fiber Links
Authors: Singh Kuldeep , Arya Sandeep K. 
Published: July 2018

Abstract
This paper evaluates the signal-to-cross talk ratio (SXR) of cross talk induced by stimulated Raman scattering (SRS) in radio-over-fiber (RoF) systems based on wavelength-division multiplexing. The reported study has modeled the relations of SXR to modulation frequency, optical power, transmission length, and effective area of fiber for various values of the walk-off parameter. The summary of experimental results reveals that SXR decreases with increases in channel input power and transmission distance and increased with increases in fiber effective area and modulation frequency. Results showed that increasing the walk-off parameter from 13.6 to 81.6 ps/km increased the SXR by almost 6 dBm. Furthermore, various fibers, including standard single-mode fiber (SMF), Corning LEAF, and Alcatel TeraLight were tested for their capacity to mitigate SRS-induced cross talk. These tests demonstrated that standard SMF suppressed SRS cross talk effectively and offered values of SXR 3 dBm and 6 dBm higher than the values exhibited by Alcatel TeraLight and Corning LEAF, respectively.
Detection of distant metastasis at the time of ablation in children with differentiated thyroid cancer: the value of pre-ablation stimulated thyroglobulin
Authors: Liu Lina , Huang Fang , Liu Bin , Huang Rui 
Published: July 2018

Abstract

Background
The present study was designed to determine the value of pre-ablation stimulated thyroglobulin (s-Tg) in predicting distant metastasis (DM) at the time of ablation in children with differentiated thyroid cancer.

Methods
From August 2009 to December 2016, consecutive children with differentiated thyroid cancer undergoing remnant ablation were retrospectively analyzed. Serum s-Tg was measured with the high-sensitive electrochemiluminescence immunoassay during hypothyroidism at ablation just before the ablative radioactive iodine (131I) administration. Post-ablation, whole body planar scintigraphy was obtained 5 days after administration of ablation activity of 131I. Single photon emission computed tomography/low-dose computed tomography (SPECT/CT) was added for children whose planar findings were inconclusive. Receiver-operating characteristics (ROC) curve analysis was employed to find a cut-off level of pre-ablation s-Tg as a predictor of DM at the time of ablation.

Results
Fifty-seven children were included for the analysis. Metastases were noticed on post-ablation scintigraphy in 20 (35%) children: five post-operative residual neck lymph node metastases, four post-operative residual neck lymph node and lung metastases, three mediastinal lymph node and lung metastases and eight lung metastases. A significant difference in pre-ablation s-Tg levels was found in children with DM compared with those without DM, 603.5 vs. 5.7 ng/mL, respectively. A pre-ablation s-Tg level of 156 ng/mL was established as the optimal cut-off point to predict DM.

Conclusions
This study demonstrated that pre-ablation s-Tg could potentially act as a predictor of DM at the time of ablation in children with differentiated thyroid cancer. We also propose a specific pre-ablation s-Tg cut-off value of 156 ng/mL as an optimal threshold for practical use.
