Detection of cosmic filaments using the Candy model
2004
We propose to apply a marked point process to automatically delineate filaments of the large-scale structure in redshift catalogues. We illustrate the feasibility of the idea on an example of simulated catalogues, describe the procedure, and characterize the results. We find the distribution of the length of the filaments, and suggest how to use this approach to obtain other statistical characteristics of filamentary networks.
Empirical Study on the Relationship between the Cross-Correlation among Stocks and the Stocks' Volatility Clustering
2013
In this paper we discuss univariate and multivariate statistical properties of volatility with the aim of understanding how these two aspects are interrelated. Specifically, we focus on the relationship between the cross-correlation among stock's volatilities and the volatility clustering. Volatility clustering is related to the memory property of the volatility time-series and therefore to its predictability. Our results show that there exists a relationship between the level of predictability of any volatility time-series and the amount of its inter-dependence with other assets. In all considered cases, the more the asset is linked to other assets, the more its volatility keeps memory of …
Subjective financial situation and financial capability of young adults in Finland
2018
A key developmental task in young adulthood is acquiring financial capability (Serido, Shim, & Tang, 2013), meaning competent financial management skills and the responsibilities that these involve. This study extends previous research on the theoretical model of the development of financial capability, including financial confidence (or financial self-efficacy) and financial behavior as factors contributing to subjective and financial well-being. It is part of the Finnish Educational Transitions Studies (FinEdu) longitudinal research project. Participants were 418 young adults aged 24–25 at Time 1 and 26–27 at Time 2. Path and mediation models and Structural Equation Modeling followin…
First-Episode Psychotic Patients Showed Longitudinal Brain Changes Using fMRI With an Emotional Auditory Paradigm
2020
Most previous longitudinal studies of functional magnetic resonance imaging (fMRI) in first-episode psychosis (FEP) using cognitive paradigm task found an increased activation after antipsychotic medications. We designed an emotional auditory paradigm to explore brain activation during emotional and nonemotional word processing. This study aimed to analyze if longitudinal changes in brain fMRI BOLD activation is present in patients vs. healthy controls. A group of FEP patients (n = 34) received clinical assessment and had a fMRI scan at baseline and follow-up (average, 25-month interval). During the fMRI scan, both emotional and nonemotional words were presented as a block design. Results w…

preparazione e caratterizzazione di nanocompositi polimero/CNTs sottoposti a stiro elongazionale
2009
Lo scopo principale di questo lavoro è rivolto alla preparazione di sistemi polimero/CNTs (in particolare a 1 e 3 % in peso di CNTs) e alla caratterizzazione reologica e meccanica dei filamenti in funzione del rapporto di stiro.
Cognitive and non‐cognitive factors in educational and occupational outcomes : Specific to reading disability?
2021
Low education and unemployment are common adult‐age outcomes associated with childhood RD (c‐RD). However, adult‐age cognitive and non‐cognitive factors associated with different outcomes remain unknown. We studied whether these outcomes are equally common among individuals with c‐RD and controls and whether these outcomes are related to adult‐age literacy skills or cognitive and non‐cognitive factors or their interaction with c‐RD. We examined adult participants with c‐RD (n = 48) and their matched controls (n = 37). Low education was more common among c‐RD than the controls, whereas long‐term unemployment was equally common in both groups. Moreover, adult‐age literacy skills, cognitive sk…
Diversity of Pharmacological Properties in Chinese and European Medicinal Plants: Cytotoxicity, Antiviral and Antitrypanosomal Screening of 82 Herbal…
2011
In an extensive screening, the antiviral, antitrypanosomal and anticancer properties of extracts from 82 plants used in traditional Chinese medicine and European phytomedicine were determined. Several promising plants that were highly effective against hepatitis B virus (HBV), bovine viral diarrhoea virus (BVDV)—a flavivirus used here as a surrogate in vitro model of hepatitis C virus, trypanosomes (Trypanosoma brucei brucei) and several cancer cell lines were identified. Six aqueous extracts from Celosia cristata, Ophioglossum vulgatum, Houttuynia cordata, Selaginella tamariscina, Alpinia galanga and Alpinia oxyphylla showed significant antiviral effects against BVDV without toxic effects …
Involvement of an Alkane Hydroxylase System of Gordonia sp. Strain SoCg in Degradation of Solid n-Alkanes▿
2010
ABSTRACT Enzymes involved in oxidation of long-chain n -alkanes are still not well known, especially those in Gram-positive bacteria. This work describes the alkane degradation system of the n -alkane degrader actinobacterium Gordonia sp. strain SoCg, which is able to grow on n -alkanes from dodecane (C 12 ) to hexatriacontane (C 36 ) as the sole C source. SoCg harbors in its chromosome a single alk locus carrying six open reading frames (ORFs), which shows 78 to 79% identity with the alkane hydroxylase (AH)-encoding systems of other alkane-degrading actinobacteria. Quantitative reverse transcription-PCR showed that the genes encoding AlkB (alkane 1-monooxygenase), RubA3 (rubredoxin), RubA4…
Data from: Vitellogenin-like A–associated shifts in social cue responsiveness regulate behavioral task specialization in an ant
2018
Division of labor and task specialization explain the success of human and insect societies. Social insect colonies are characterized by division of labor with workers specializing on brood care early and foraging later in life. Theory posits that this task switching requires shifts in responsiveness to task-related cues, yet experimental evidence is weak. Here we show that a Vitellogenin (Vg) ortholog identified in a RNAseq study on the ant Temnothorax longispinosus is involved in this process: Using phylogenetic analyses of Vg and Vg-like genes, we firstly show that this candidate gene does not cluster with the intensively studied honey bee Vg, but falls into a separate Vg-like A cluster.…
