Discovering hidden brain network responses to naturalistic stimuli via tensor component analysis of multi-subject fMRI data

2021

The study of brain network interactions during naturalistic stimuli facilitates a deeper understanding of human brain function. To estimate large-scale brain networks evoked with naturalistic stimuli, a tensor component analysis (TCA) based framework was used to characterize shared spatio-temporal patterns across subjects in a purely data-driven manner. In this framework, a third-order tensor is constructed from the timeseries extracted from all brain regions from a given parcellation, for all participants, with modes of the tensor corresponding to spatial distribution, time series and participants. TCA then reveals spatially and temporally shared components, i.e., evoked networks with the …

Measuring the ‘Bridging’ versus ‘Bonding’ Nature of Social Networks: A Proposal for Integrating Existing Measures

2010

Recent research illustrates that two distinct interpretations and operationalizations of ‘bridging’ and ‘bonding’ social networks co-exist in the literature (based on links between diverse networks or between socio-economic groups within a given network, respectively), and that these do not coincide in empirical applications. The present contribution first confirms this conclusion using data from the United Kingdom. Then, we suggest a simple way to integrate both existing approaches into a more general measure of bridging and bonding. Applying this more general index to UK and Flemish data, a) provides stronger empirical support for the idea that memberships in bridging groups are more str…

Ode laica per Chibok e Leah

2019

The volume contains two short poems by Nigerian Nobel Laureate Wole Soyinka ("No, He Said!", dedicated to Nelson Mandela, from the Author's 1988 classic collection "Mandela's Earth and Other Poems", and the recent "Mandela Comes to Leah", written purposely for this volume), along with the most recent long poem in five parts "A Humanist Ode to Chibok, Leah", published in English for the first time in 2019. The poem, and indeed the entire volume, denounces all forms of fundamentalism and fanaticism as opposed to secular humanism. Soyinka pays tribute to the girls abducted in Chibok and 15 year-old Leah Sharibu, one of the 108 girls abducted from Dapchi in 2018, comparing her firm refusal to r…

Fast dendrogram-based OTU clustering using sequence embedding

2014

Biodiversity assessment is an important step in a metagenomic processing pipeline. The biodiversity of a microbial metagenome is often estimated by grouping its 16S rRNA reads into operational taxonomic units or OTUs. These metagenomic datasets are typically large and hence require effective yet accurate computational methods for processing.In this paper, we introduce a new hierarchical clustering method called CRiSPy-Embed which aims to produce high-quality clustering results at a low computational cost. We tackle two computational issues of the current OTU hierarchical clustering approach: (1) the compute-intensive sequence alignment operation for building the distance matrix and (2) the …

Binding of Bacillus thuringiensis toxins in resistant and susceptible strains of pink bollworm (Pectinophora gossypiella)

2003

Abstract Evolution of resistance by pests could cut short the success of transgenic plants producing toxins from Bacillus thuringiensis, such as Bt cotton. The most common mechanism of insect resistance to B. thuringiensis is reduced binding of toxins to target sites in the brush border membrane of the larval midgut. We compared toxin binding in resistant and susceptible strains of Pectinophora gossypiella, a major pest of cotton worldwide. Using Cry1Ab and Cry1Ac labeled with 125I and brush border membrane vesicles (BBMV), competition experiments were performed with unlabeled Cry1Aa, Cry1Ab, Cry1Ac, Cry1Ba, Cry1Ca, Cry1Ja, Cry2Aa, and Cry9Ca. In the susceptible strain, Cry1Aa, Cry1Ab, Cry1…

Contrasting temperature responses in seasonal timing of cercariae shedding by Rhipidocotyle trematodes

2022

AbstractGlobal warming is likely to lengthen the seasonal duration of larval release by parasites. We exposed freshwater mussel hosts, Anodonta anatina, from 2 high-latitude populations to high, intermediate and low temperatures throughout the annual cercarial shedding period of the sympatric trematodes Rhipidocotyle fennica and R. campanula, sharing the same transmission pathway. At the individual host level, under warmer conditions, the timing of the cercarial release in both parasite species shifted towards seasonally earlier period while its duration did not change. At the host population level, evidence for the lengthening of larvae shedding period with warming was found for R. fennica…

Innovating business processes in public administrations: towards a systemic approach

2020

PurposeThe purpose of this paper is to study the credit collection process in public administrations in order to develop a conceptual model which goes beyond the traditional logic of linearity, adopting system thinking approaches.Design/methodology/approachThis study analyses the case of an Italian local government-owned enterprise. Data collection through semi-structured interviews and document analysis has enabled the development of propositions, the identification of systemic variables, and the development of an explanatory modeling process based on the system dynamics approach.FindingsThis paper shows that public administrations can effectively involve external actors, especially citize…
