Supporting Tools for Blended Animators in Complex Learning Communities

– The society model of the last years has given a key role to knowledge in terms of economic and social development. On this background, is allocated the success of the communities of practice, and more recently, of the Complex Learning Community model, whose strength is represented by the ability to provide students, educators, and professionals with a common creative space to develop not only knowledge and expertise, but also ideas, synergies, chances. In both cases, particular emphasis is given to the interactions between users as a "place" where knowledge emerges, is built and delivered. Our former paper was dedicated to the communities of practice, and in particular, to the use of an intelligent agent to control and lead the interaction among users; now our research concerns environments for collaborative learning, where the role of the animator is fundamental, but we take into account a blended animator, supported by specific tools to manage the community. Such tools are necessarily connected to the comprehension and elaboration of the natural language which highlights the appropriate knowledge elements to be used. In this paper we intend to analyse the available techniques in order to identify those that are more suitable for designing the supporting tools required by the blended animator. Particular attention will be given to the domain ontology.
POLICE USE OF SOCIAL MEDIA: COMPARING CLASSIFICATION METHODS

With the advent of social media data, and in the pursuit of understanding meaning behind those data, text classification continues to grow in importance. Domain expertise is often needed to classify text effectively, but it is unlikely to be found in the tools that provide the means for unsupervised classification. This paper examines a variety of text classification techniques applied to the domain of policing in the U.S. With police and their interaction with the public being in the public spotlight, understanding the messaging police send out via social media offers important insight into how the relationship between the police and the public evolves over time. However, classifying the tweets being sent out via the thousands of police forces across the U.S. is a daunting task. This work tests whether this classification can be automated, and explores the ramifications if it is.
Seed germination and seedling vigour as influenced by pregermination seed treatment in Himalayan Dogwood (Benthamidia capitata Wall ex. Roxb.)

Influence of different treatments on seed germination and seedling vigour of Benthamidia capitata, involving water soaking (8, 16, 24, 32, 40, and 48 h), gibberellic acid soaking (100, 200, 300, 400, 500, and 600 mg− 1), and sulphuric acid scarification (3, 6, 9, 12, 15, and 18 min), was studied to identify the best responding presowing seed treatments. The greater seed germination, root, shoot, and seedling length, along with vigour index, were observed for 32 h water soaking, while 300 mg− 1 of GA3 treatment gave maximum seed germination and seedling vigour. However, seed treated in sulphuric acid for 6 min produced the maximum number of elite seedlings. Among the pretreatments, sulphuric acid was found to be the most effective scarifying agent for breaking physical seed dormancy, but the risk associated with the handling of acid for both seeds and humans requires consideration. In this context, water soaking for 32 h appears to be the most promising method for nursery growers as it is eco-friendly, economical, and easy to apply.
Influence of interleukin-18 polymorphisms on kidney transplantation outcomes: A meta-analysis

Aim: Allograft survival post-kidney transplantation (KT) are in large part attributed to genetics, which render the recipient susceptible or protected from allograft rejection. KT studies involving single nucleotide polymorphisms (SNPs) have reported the association of interleukin-18 (IL-18) with KT and its role in allograft rejection. However, the reported outcomes been inconsistent, prompting a meta-analysis to obtain more precise estimates. Methods: We posed two hypotheses about the IL-18 SNPs: their association with KT (H1), and increase or decrease in the risks of allograft rejection (H2). Using standard genetic models, we estimated odds ratios [ORs] and 95% confidence intervals by comparing the IL-18 genotypes between two groups: (i) patients and controls for H1 (GD: genotype distribution analysis); (ii) rejectors and non- rejectors for H2 (allograft analysis). Multiple comparisons were corrected with the Holm-Bonferroni (HB) test. Subgrouping was ethnicity-based (Asians and Caucasians). Heterogeneity was outlier-treated and robustness of outcomes was sensitivity-treated. Results: This meta-analysis generated eight significant outcomes, which HB filtered into four core outcomes, found in the dominant/codominant models. Two of the four were in GD, indicating associations of the IL-18 SNPs with KT (ORs 1.34 to 1.39, 95% CIs 1.13-1.70, PHB = .0007-.004). The other two were in allograft analysis indicating reduced risk with HB P-values of . 03 for overall (OR 0.74, 95% CI 0.56-0.93) and Asian (OR 0.70, 95% CI 0.53-0.92). In contrast to the protected Asian subgroup, Caucasians showed non-significant increased risk (OR 1.20. 95% CI .82-1.75, Pa = .35). Sensitivity treatment conferred robustness to all the core outcomes. Conclusions: Overall association of IL-18 SNPs with KT was significant (up to 1.4-fold) and Asians KT recipients were protected (up to 30%). Enabled by outlier treatment, these findings were supported by non-heterogeneity and robustness. More studies may confirm or modify our findings.
Risk factors of coronary microvascular obstruction

Background. Coronary microvascular obstruction /no-reflow(CMVO/NR) is a predictor of long-term mortality in survivors of ST elevation myocardial infarction (STEMI) underwent primary percutaneous coronary intervention (PPCI). Objective. To identify risk factors of CMVO/NR. Methods.Totally 2384 STEMI patients treated with PPCI were divided into two groups according to thrombolysis in myocardial infarction(TIMI) flow grade:CMVO/NR group(246cases,TIMI 0-2 grade) and control group(2138 cases,TIMI 3 grade). We used univariable and multivariable logistic regression to identify risk factors of CMVO/NR. Results. A frequency of CMVO/NR was 10.3%(246/2384). Logistic regression analysis showed that the differences between the two groups in age(unadjusted odds ratios [OR] 1.032; 95% CI, 1.02 to 1.045; adjusted OR 1.032; 95% CI, 1.02 to 1.046 ; P <0.001), periprocedural bradycardia (unadjusted OR 2.357 ; 95% CI, 1.752 to 3.171; adjusted OR1.818; 95% CI, 1.338 to 2.471 ; P <0.001),using thrombus aspirationdevices during operation (unadjusted OR 2.489 ; 95% CI, 1.815 to 3.414; adjusted OR1.835; 95% CI, 1.291 to 2.606 ; P =0.001),neutrophil percentage (unadjusted OR 1.028 ; 95% CI, 1.014 to 1.042; adjusted OR1.022; 95% CI, 1.008 to 1.036 ; P =0.002) , and completely block of culprit vessel (unadjusted OR 2.626; 95% CI, 1.85 to 3.728; adjusted-OR 1.656;95% CI, 1.119 to 2.45; P =0.012) were statistically significant ( P <0. 05). The area under the receiver operating characteristic curve was 0.6896 . Conclusions. Age , periprocedural bradycardia, using thrombus aspirationdevices during operation, neutrophil percentage ,and completely block of culprit vessel may be independent risk factors for predicting CMVO/NR.

Optimization of Next-Generation Alcohols and Fishoil Methyl Ester Blends In a Single Cylinder DI-CI Engine using Response Surface Methodology

The present investigation delivers a comprehensive viewpoint on the current artificial intelligence (AI) metamodelling in diesel engine system, particularly in the domains of multi-objective optimization. The relevance to the benefits of AI built modelling stratagems, and the probable Response Surface Methodology has been efficient with the consecutive growth in the current domains of the compression ignition technology. The study establishes the fundamental significance of inspecting certain multi-objective optimization stratagems matching with the accumulating need to deal with emission-performance trade-off trials of the compression ignition technology. To achieve the reliability and versatility of such model centered multi-objective optimization strategies, the current study delivers a unique casestudy presenting the creditably accurate model-based standardization in an existing diesel engine. Therefore, nOctanol produced in renewable ways, methyl esters of fish oil (MEFO) blended with diesel is used as fuel and the experiments were designed by Design of Experiments (DoE) based on response surface methodology (RSM) architecture. The results depicted that the tailor-made fuels proved their ability in terms of both performance and emissions when compared to mineral diesel. The model is further tested on a statistical platform with some special error matrices like Mean Squared Relative Error, MSRE, and Nash–Sutcliffe Coefficient of Efficiency, NCE along with conventional model testing metrics like MSE, RMSE and R which proved that the proposed model is robust and efficient in predicting the input-output paradigm. The ranges of correlation coefficients R, R2 and NCE are 0.99786 - 0.999992, 0.99786- 0.999992 and 0.9957 – 0.999984 respectively. And the ranges of the error metrics Theil U2 and MSRE are 0.004048 0.065246 and 6.07E-07 to 0.000158 respectively. Optimization of input parameters was performed using the desirability approach of the response surface methodology for better performance and lower NOx and CO emission at a desirability index of 0.986. Experimental validation suggested a blend of 20% MEFO and 10% n-Octanol with petrodiesel at full loads were found to be optimal values for the test engine.
Padé Approximant Using ISCZ Method

Padé approximant is a rational approximation constructed from the coefficients of a power series of a given input function. Padé approximant may be obtained by the extended Euclidean algorithm, but the algorithm is unstable when the computations are performed in floating-point arithmetic. In this paper, we utilize the ISCZ method to stabilize the numerical computations of Padé approximants using the extended Euclidean algorithm. Experimental results show that the proposed method can guarantee the correct solutions with less CPU time and smaller memory usage compared to those of a normal extended Euclidean algorithm in the case of the power series with coefficients over Q(e).
Ice Cream Nutrition and Its Health Impacts

Ice cream is a sweetened frozen dairy product preferred as snacks or dessert made of milk and milk products that is often added with fruits along with other essential ingredients like flavors colors. The objective of this review is to assess nutritional and health impacts of ice cream to identify the nutritional advantage and also its impacts on health. Ice cream are classified based on their ingredients and flavor used. Ice composes high sugars (20.7mg/100g) and fat (16mg/100gm) and other compositions like minerals, vitamins. Ice cream is a nutritious product which is very conducive for microbial growth specially, pathogenic organisms that cause a food borne out break. Some studies suggest that ice cream can be used as probiotic carrier but due to its high fat and sugar contents it may be unhealthy food for many individual. But, some studies have been conducted to find sugar substitute with little success because of organoleptic sensory impairment. By combining the two ideas (probiotics incorporation and reduction of fat and sugar) the ice cream consumption and its marketing have a chance to be grown fast.
The variability of the proton cosmic ray flux in and outside spiral arms. First results from calculations over long propagation times

Supernovae (SN) are the most likely sources of galactic cosmic rays. Since the most frequent SN types Ib and II are found within spiral arms, one can expect a significant difference in the range of possible spectra inside and outside spiral arms. We investigate the variability of the local interstellar cosmic ray proton spectrum during the motion of the Sun in and out of spiral arms along its journey around the galactic center. For this we calculated the cosmic ray density over a period of 100 Myr to allow for one spiral crossing at a given point at the galactocentric distance of the Sun.
Issues in Information Systems

The prevention of adverse drug events calls for the use of medication safety apps by providers as well as healthcare consumers. To inform the design of medication safety apps, the influence of value-in-experience—information quality, subjective quality, functionality, engagement, and aesthetics—on perceived impact of medication safety apps was investigated. Participants were asked to perform a task using one of three medication safety apps, and following the task, they were administered a questionnaire measuring their value-in-experience and perceived impact. For analysis, the hierarchical latent variable PLS-SEM was employed, using the repeated indicator approach. Across three medication safety apps, we found that value-in-experience influences perceived impact. Information quality and subjective quality influence perceived impact. Functionality, engagement, and aesthetics did not influence perceived impact. Developers and investigators are advised to give equal or more attention to information quality and subjective quality compared to other aspects of medication safety app user experience.
Reversible Inhibitory Effects of Interferon‐γ and Tumour Necrosis Factor‐α on Oligodendroglial Lineage Cell Proliferation and Differentiation In Vitro

We have investigated the effects of the two prominent inflammatory cytokines, interferon‐γ (IFN‐γ) and tumour necrosis factor‐α (TNF‐α), on oligodendroglial lineage cell development and survival. Purified oligodendrocytes and oligodendrocyte precursors obtained from neonatal rat brain primary cultures were subcultured in a defined, serum‐free medium and exposed to IFN‐γ (1‐100 U/ml), TNF‐α (25‐100 ng/ml) or both (100 U/ml and 50 ng/ml respectively) from day 1 to day 3 or from day 3 to day 6. While cell survival was not affected in any of the conditions tested, IFN‐γ dose‐dependently inhibited [3H]thymidine or bromodeoxyuridine incorporation (by up to 50%) and the reduction of the tetrazolium salt 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide (MTT; by up to 33%). TNF‐α synergized with IFN‐γ, but was ineffective by itself. Moreover, IFN‐γ totally antagonized the induction by basic fibroblast growth factor and platelet‐derived growth factor of the proliferation of the oligodendroglial lineage cell population under study. IFN‐γ also blocked the differentiation of oligodendrocyte precursors, as evidenced by cell morphology, immunostaining for early and late differentiation markers (galactocerebroside and myelin basic protein respectively) and activity of ceramide galactosyl transferase. Again, the effect of IFN‐γ was potentiated by TNF‐α, which was ineffective when tested alone. The inhibitory activity of IFN‐γ was rapidly reversible: 3 days after removal of the cytokine, administered from day 1 to day 3, complete recovery of cell proliferation and differentiation could be documented. The cytokine‐induced arrest in the expression of differentiation antigens was accompanied by perturbations in the expression of the corresponding mRNAs, revealed by a semiquantitative reverse transcription‐polymerase chain reaction method. In particular, the message for myelin basic protein (and, in the case of treatment from days 3 to 6, also that for myelin associated glycoprotein) was decreased in cultures exposed to IFN‐γ, and further depressed in cultures treated with IFN‐γ and TNF‐α, while TNF‐α alone was ineffective. The above observations may help explain the role of IFN‐γ and TNF‐α in the pathogenesis of inflammatory demyelinating diseases, in which increases in the levels of these substances have been described. In particular, in the case of multiple sclerosis, our results may bear on the problem of defective remyelination and are consistent with the frequent relapsing‐remitting course of the disease.
Pigment dispersion by prolactin in cultured xanthophores and erythrophores of some fish species

The direct effects of a pair of tilapia prolactins (tPRL177 and tPRL188) and of ovine prolactin (oPRL) on cultured xanthophores and erythrophores isolated from some fish species were examined. Cultured xanthophores of the Nile tilapia, paradise goby, and medaka responded to tPRL177 and oPRL at concentrations of less than 100 nM by pigment dispersion, whereas tPRL188 had an effect only at concentrations of 10 μM or more. Swordtail erythrophores also responded to prolactin even in winter. It is likely, therefore, that in fish species possessing many xanthophores or erythrophores in their skin throughout the year, these cells respond to prolactin all the time. In fall and/or winter, prolactin had little or no effect on xanthophores isolated from the dark chub and rose bitterling or on erythrophores from the tilapia and paradise goby. However, it was shown that xanthophores of the rose bitterling and erythrophores of the tilapia responded better to prolactin in spring and/or summer as compared with fall and/or winter. Such seasonal change in the responsiveness of the cells to prolactin implies the involvement of the hormone in nuptial coloration and an augmentation of red and/or yellow skin color by pigment dispersion in the spawning season. Prolactin-induced pigment dispersion within erythrophores isolated from the red region of tail fins of the rose bitterling assuming nuptial coloration also lends support to this supposition. © 1996 Wiley-Liss, Inc.
Locally and Remotely Generated Wind Waves in the Southwestern Shelf Sea of India

ABSTRACT Anoop, T.R. ; Sheela Nair, L. ; Prasad, R. ; Reji, S. ; Ramachandran, K.K. ; Prakash, T.N. , and Balakrishnan Nair, T.M. , 2020. Locally and remotely generated wind waves in the southwestern shelf sea of India. In: Sheela Nair, L. ; Prakash, T.N. ; Padmalal, D. , and Kumar Seelam, J. (eds.), Oceanic and Coastal Processes of the Indian Seas. Journal of Coastal Research, Special Issue No. 89, pp. 77-83. Coconut Creek (Florida), ISSN 0749-0208. The Southwestern Shelf Sea (SWSS) of India has a distinct wave pattern, which makes it different as compared to the adjoining regions. Wave directional spectra during the monsoon season are comparatively broader and double peaked in contrast to that of the western shelf sea. The well-defined directional bi-modality is observed during the south west monsoon which is attributed to the coexistence of the south Indian Ocean swells and the southwest monsoon swells. The shamal swells generated by the shamal wind blowing from the Arabian Peninsula are found to have a significant influence on the wave pattern of the SWSS. In addition, the local sea breeze/land breeze also contributes significantly to the observed changes, particularly to the diurnal variation. A distinct phase lag in occurrence of the maximum significant wave height for the wind sea component is also observed in the northern region of the SWSS during the fair seasons.
The Complete Mitochondrial Genome of the Near-Threatened Swallowtail, Agehana maraho (Lepidoptera: Papilionidae): Evaluating Sequence Variability and Suitable Markers for Conservation Genetic Studies

ABSTRACT: Agehana maraho (Shiraki and Sonan, 1934) is a near-threatened swallowtail butterfly endemic to Taiwan. As a first step in evaluating the most variable molecular markers for further population genetic and conservation studies of this and other insects, the entire mitochondrial genome (mitogenome) was sequenced (16,094bp). The most distinctive structure of the Agehana mitogenome is the control region (CR; 1,270bp). This is the longest CR found so far in any lepidopteran, and it also represents the first known case of two units of macro repeats within a tandem region. In a comparison with another 12 lepidopteran mitogenomes, the genes atp8, atp6, and nad6 were found to be more variable than cox1, suggesting an undue focus on cox1 (COI) in identification and phylogeographic studies. A combination of these first three genes plus the CR, comprising micro as well as macro repeats, may thus provide more suitable markers for conservation genetic studies, not only of this near-threatened species, but also of many other insects.
Sensitivity of Subsurface Processes of Equatorial Pacific Ocean to the Heat and Momentum Fluxes: A Case Study of 1997-98 El Niño

ABSTRACT Ananya, K. ; Anant, P.; Chowdary, J.S. , and Gnanaseelan, C. , 2020. Sensitivity of subsurface processes of equatorial Pacific Ocean to the heat and momentum fluxes: A case study of 1997-98 El Niño. In: Sheela Nair, L. ; Prakash, T.N. ; Padmalal, D. , and Kumar Seelam, J. (eds.), Oceanic and Coastal Processes of the Indian Seas. Journal of Coastal Research, Special Issue No. 89, pp. 26-31. Coconut Creek (Florida), ISSN 0749-0208. The influence of accurate heat and momentum fluxes on 1997-98 El Niño simulation is investigated using Geophysical Fluid Dynamics Laboratory (GFDL) ocean model Modular Ocean Model version 5 (MOM5). Control experiment (CTRL) is carried out by using surface forcing from the CORE2 inter-annual flux, whereas sensitivity experiment (OAERA) is carried out by using heat fluxes from WHOI Objectively analysed air-sea fluxes (OAFlux) data and momentum fluxes from ERA-interim (ERA-I). Both experiments are carried out for a common period of 1985-2009. These experiments revealed that the strength of inter-annual variability is sensitive to accuracy of the forcing. In particular, the sensitivity experiment displayed better simulation of 1997-98 El Niño features such as developing and peak phases. The strength of Niño indices (mainly Niño 3 and Niño 3.4) in OAERA is comparable to EN 4/ORAS 3 more than CTRL. Further analysis reveals that throughout the equatorial Pacific Ocean upper ocean temperature anomaly evolution during the developing to peak phase is improved in OAERA, which is further confirmed by the mixed layer temperature anomaly tendency (TAT) evolution. Detailed analysis of dynamical feedback contribution to TAT indicates that in CTRL, thermocline and zonal advection feedbacks are overestimated and their temporal evolution is inconsistent compared to ORAS 3, whereas these feedbacks are consistent in OAERA, leading to better simulation of Niño indices. Our study concludes that accurate heat flux and momentum flux forcing can improve the simulation of Niño indices and equatorial Pacific upper ocean temperature anomaly associated with the strong El Niño 1997-98.
Edge detection in images using energy characteristics

The paper considers a new approach to image edges detecting. It is based on the weight image model application. In this model, image pixels are evaluated in terms of their importance for perception. For this we use energy signs, the calculation of which is based on the wavelet transform. The proposed approach allows you to create an effective edge detector for use in various computer vision systems, for example, in aviation systems, traffic control systems, road surface monitoring systems, biometric identification systems, etc.
