... Are Individual Differences Quantitative Or Qualitative? An Integrated Behavioral And Fmri Mimic Approach. Authors: Jacqueline N. Zadelaar, Wouter D. Weeda, Lourens J. Waldorp, Anna C. K. Van Duijvenvoordee, N. E. Blankenstein, Hilde M. Huizenga In cognitive neuroscience there is a growing interest in individual differences. We propose the Multiple Indicators Multiple Causes (MIMIC) model of combined behavioral and fMRI data to determine whether such differences are quantitative or qualitative in nature. A simulation study revealed the MIMIC model to have adequate power for this goal, and parameter recovery to be satisfactory. The MIMIC model was illustrated with a re-analysis of Van Duijvenvoorde et al. (2016) and Blankenstein et al. (2018) decision making data. This showed individual differences in Van Duijvenvoorde et al. (2016) to originate in qualitative differences in decision strategies. Parameters indicated some individuals to use an expected value decision strategy, while others used a loss minimizing strategy, distinguished by individual differences in vmPFC activity. Individual differences in Blankenstein et al. (2018) were explained by quantitative differences in risk aversion. Parameters showed that more risk averse individuals preferred safe over risky choices, as predicted by heightened vmPFC activity. We advocate using the MIMIC model to empirically determine, rather than assume, the nature of individual differences in combined behavioral and fMRI datasets.

Rearrangements within the U6 snRNA core during the transition between the two catalytic steps of splicing. Eysmont et al.
Contributors: Katarzyna Eysmont
... The RNA catalytic core of spliceosomes as visualized by cryo-EM remains unchanged at different stages of splicing. However, we demonstrate that mutations within the core of yeast U6 snRNA modulate conformational changes between the two catalytic steps. We propose that the intramolecular stem-loop (ISL) of U6 exists in two competing states, changing between a default, non-catalytic conformation and a transient, catalytic conformation. Whereas stable interactions in the catalytic triplex promote catalysis and their disruptions favor exit from the catalytic conformation, destabilization of the lower ISL stem promotes catalysis and its stabilization supports exit from the catalytic conformation. Thus, in addition to the catalytic triplex, U6-ISL acts as an important dynamic component of the catalytic center. The relative flexibility of the lower U6-ISL stem is conserved across eukaryotes. Similar features are found in U6atac and domain V of group II introns, arguing for the generality of the proposed mechanism.

Migrants in the media: a quantitative analysis of print media in Spain, Belgium and Germany in the context of the upcoming 2019 European elections.
Contributors: Kate Jackson, Ariane Gemander
... The matter of migrant related discourses has been a prominent theme in political debates and public discussions leading up to the European elections. The ways in which migration and migrants are framed in the discourse encompases how migration is percieved and constructed in the general consciousness, and has an observable effect on political developments around the world. Media portrayals of migrants influences local communities’ perception and openness to newcomers. Entrance into a community requires participation from both the migrants, and the local communities. This research has been pursued in order to better understand the discursive way in which migrants are being contextualized in the media in three European countries. This study offers a quantitative analysis of nine online newspapers from Germany, Spain and Belgium. Data has been gathered over a two month period to create a lexical database that can be regarded as a whole, or observed as lexical developments over the two months leading up to the elections. To conduct the quantitative analysis, the researchers used TXM, a digital tool that supports the statistical analysis of large volumes of text. Through creating a lexical corpus, the researchers have codified recurring words and “lexical environments” of keywords that the researchers specifically targeted. Analyzing the results against a literary review of previous analysis for each of the three countries provides us with a point of analysis of how migrants are being presented in the discourse. This work is designed to help better understand the ways in which migrants are being depicted to local populations as this framing has been shown to affect voting patterns and the political landscape.
Kinetic model: of the work (Detailed Kinetic Mechanism for the Oxidation of Ammonia Including the Formation and Reduction of Nitrogen Oxides)
Contributors: Krishna prasad Shrestha
... This work introduces a newly developed reaction mechanism for the oxidation of ammonia in freely propagating and burner-stabilized premixed flames as well as shock-tube, jet-stirred reactor, and plug-flow reactor experiments. The paper mainly focuses on pure ammonia and ammonia–hydrogen fuel blends. The reaction mechanism also considers the formation of nitrogen oxides as well as the reduction of nitrogen oxides depending upon the conditions of the surrounding gas phase. Doping of the fuel blend with NO2 can result in acceleration of H2 autoignition via the reaction NO2 + HO2 ⇋ HONO + O2, followed by the thermal decomposition of HONO, or deceleration of H2 oxidation via NO2 + OH ⇋ NO + HO2. The concentration of HO2 is decisive for the active reaction pathway. The formation of NO in burner-stabilized premixed flames is shown to demonstrate the capability of the mechanism to be integrated into a mechanism for hydrocarbon oxidation. This mechanism is the supplementary material to the work: Detailed Kinetic Mechanism for the Oxidation of Ammonia Including the Formation and Reduction of Nitrogen Oxides. https://pubs.acs.org/doi/10.1021/acs.energyfuels.8b01056 https://doi.org/10.1021/acs.energyfuels.8b01056 The above (link) mentioned article should be properly cited when used for research work and publication.
Predicted distribution of the glass sponge Vazella pourtalesi on the Scotian Shelf and its persistence in the face of climatic variability
Contributors: Lindsay Beazley, zeliang wang, Ellen Kenchington, Igor Yashayaev, Hans Tore Rapp, Joana R. Xavier, Francisco Javier Murillo, Derek Fenton, Susanna Fuller
... Emerald Basin on the Scotian Shelf off Nova Scotia, Canada, is home to a globally unique aggregation of the glass sponge Vazella pourtalesi, first documented in the region in 1889. In 2009, Fisheries and Oceans Canada (DFO) implemented two Sponge Conservation Areas to protect these sponge grounds from bottom fishing activities. Together, the two conservation areas encompass 259 km2. In order to ascertain the degree to which the sponge grounds remain unprotected, we modelled the presence probability and predicted range distribution of V. pourtalesi on the Scotian Shelf using random forest modelling on presence-absence records. With a high degree of accuracy the random forest model predicted the highest probability of occurrence of V. pourtalesi in the inner basins on the central Scotian Shelf, with lower probabilities at the shelf break and in the Fundian and Northeast Channels. Bottom temperature was the most important determinant of its distribution in the model. Although the two DFO Sponge Conservation Areas protect some of the more significant concentrations of V. pourtalesi, much of its predicted distribution remains unprotected (over 99%). Examination of the hydrographic conditions in Emerald Basin revealed that the V. pourtalesi sponge grounds are associated with a warmer and more saline water mass compared to the surrounding shelf. Reconstruction of historical bottom temperature and salinity in Emerald Basin revealed strong multi-decadal variability, with average bottom temperatures varying by 8˚C. We show that this species has persisted in the face of this climatic variability, possibly indicating how it will respond to future climate change.
