High-energy γ-ray detection of supernova remnants in the Large Magellanic Cloud
2022
We present the results of a cluster search in the gamma-ray sky images of the Large Magellanic Cloud (LMC) region by means of the Minimum Spanning Tree (MST) and DBSCAN algorithms, at energies higher than 6 and 10 GeV, using 12 years of Fermi-LAT data. Several significant clusters were found, the majority of which associated with previously known gamma-ray sources. We confirm our previous detection of the Supernova Remnants N 49B and N 63A and found new significant clusters associated with the SNRs N 49, N 186D and N 44. These sources are among the brightest X-ray remnants in the LMC and corresponds to core-collapse supernovae interacting with dense HII regions, indicating that an hadronic …
Mocking fakeness
2022
Abstract Phonetic resources, like dialects and accents, are used in ethnic humour to build up a recognisable character that pokes fun at the stereotypes associated with a particular identity, sometimes with critical and political undertones. In this article, we examine the manipulation of one such resource, aspiration, used in performing and mocking one such clichéd character, called the fake Sámi. This character has a contested history in Finnish tourism and marketing practices, and is embedded in a long-standing debate about who can use emblems of Sámi identity for economic purposes. Adopting a sociophonetic language regard and folk linguistics approaches (Preston 2010; Niedzielski & …
Manipulation as an ideological tool in the political genre of Parliamentary discourses
2022
AbstractThe present study analyzes the discursive strategies of manipulation in the political genre of a discourse in Parliament with an aim to convince the audience that the Prime Minister and his party are innocent of receiving illegal cash donations from a slush fund run in the party. For that purpose, we have usedVan Dijk’s (2006)scheme of strategies of manipulation at several levels of discourse (content, lexis, topics, syntax, rhetoric, and order of discourse). Findings of the study show that the Prime Minister’s speech presents characteristics of ideological discourse, since it follows a general strategy of positive in-group and negative out-group presentation, which has an overall l…

Associations between having breakfast and reading literacy achievement among Nordic primary school students
2022
Having breakfast is associated with improved diet quality, cognitive- and academic performance and can therefore positively impact learning and health, although the impact on reading literacy is unknown in the Nordic countries. The aim of this study was to assess the association between having breakfast often versus rarely and reading literacy achievement based on Progress in International Reading Literacy Study (PIRLS) from 2016. The sample consisted of Danish (N = 3508), Finnish (N = 4896), Norwegian (N = 4232) and Swedish (N = 4525) students, 10–11 years old. Students self-reported their frequency of having breakfast. Linear regression analysis (adjusted for socio-economic status and gen…
Adaptive scheduling of acceleration and gyroscope for motion artifact cancelation in photoplethysmography
2022
Background and objective: Recently, various algorithms have been introduced using wrist-worn photo-plethysmography (PPG) to provide high accuracy of instantaneous heart rate (HR) estimation, including during high-intensity exercise. Most studies focus on using acceleration and/or gyroscope signals for the motion artifact (MA) reference, which attenuates or cancels out noise from the MA-corrupted PPG signals. We aim to open and pave the path to find an appropriate MA reference selection for MA cancelation in PPG.Methods: We investigated how the acceleration and gyroscope reference signals correlate with the MAs of the distorted PPG signals and derived both mathematically and experimentally a…

Identifying conserved genes involved in crop tolerance to cold stress
2022
Low temperature is a limiting factor for crop productivity in tropical and subtropical climates. Cold stress response in plants involves perceiving and relaying the signal through a transcriptional cascade composed of different transduction components, resulting in altered gene activity. We performed a meta-analysis of four previously published datasets of cold-tolerant and cold-sensitive crops to better understand the gene regulatory networks and identify key genes involved in cold stress tolerance conserved across phylogenetically distant species. Re-analysing the raw data with the same bioinformatics pipeline, we identified common cold tolerance-related genes. We found 236 and 242 common…
The Role of Existential Concerns in the Individual’s Decisions regarding COVID-19 Vaccine Uptake: A Survey among Non-Vaccinated Italian Adults during…
2022
Recent studies have suggested that health constructs embraced by the Terror Management Theory (TMT) and the Basic Psychological Needs Theory (BPNT) may drive individuals’ COVID-19 health-related decisions. This study examines the relationships between existential concerns (ECs; within the TMT), basic psychological needs (BPNs; within the BPNT) and COVID-19 vaccine hesitancy (VH), as well as the mediating role of negative attitudes toward COVID-19 vaccines. A cross-sectional survey was carried out from April to May 2021 on a sample of two hundred and eighty-seven adults (Mage = 36.04 ± 12.07; 59.9% females). Participants provided information regarding existential concerns, basic psychologica…
Vitamin D 25OH Deficiency and Mortality in Moderate to Severe COVID-19: A Multi-Center Prospective Observational Study.
2022
IntroductionSeveral studies and meta-analyses suggested the role of vitamin D 25OH in preventing severe forms of coronavirus disease 2019 (COVID-19). However, the evidence on the clinical benefits of vitamin D 25OH adequacy in patients hospitalized for COVID-19 remain conflicting and speculative. We aimed to investigate the association between vitamin D 25OH serum levels and mortality in hospitalized patients with moderate to severe COVID-19.MethodThis prospective observational multicentre study included 361 consecutive patients with moderate to severe COVID-19 admitted to the Italian hospitals involved in the NUTRI-COVID19 trial from March to August 2020. For each patient, serum vitamin D …

Ultra-conserved elements provide insights to the biogeographic patterns of three benthic macroinvertebrate species in the Baltic Sea
2022
The Baltic Sea, with its steep salinity gradient, high water retention time, and relatively young age, represents a marginal ecosystem between marine and freshwater extremes. Due to differing invasion history and dispersal capabilities of Baltic species, there are large differences in species distributions, species-specific genetic structure and variation, and edge populations that may represent both a subset of the original population, as well as unique genetic lineages. We used a phylogenomic approach to investigate relationships between populations of three benthic macroinvertebrate species: Pygospio elegans, Corophium volutator, and Mya arenaria, providing new insight into evolutionary …
Hands-feet wireless devices: Test-retest reliability and discriminant validity of motor measures in Parkinson's disease telemonitoring
2022
Background Telemonitoring, a branch of telemedicine, involves the use of technological tools to remotely detect clinical data and evaluate patients. Telemonitoring of patients with Parkinson's disease (PD) should be performed using reliable and discriminant motor measures. Furthermore, the method of data collection and transmission, and the type of subjects suitable for telemonitoring must be well defined. Objective To analyze differences in patients with PD and healthy controls (HC) with the wearable inertial device SensHands-SensFeet (SH-SF), adopting a standardized acquisition mode, to verify if motor measures provided by SH-SF have a high discriminating capacity and high intraclass corr…

First and second critical exponents for an inhomogeneous Schrödinger equation with combined nonlinearities
2022
AbstractWe study the large-time behavior of solutions for the inhomogeneous nonlinear Schrödinger equation $$\begin{aligned} iu_t+\Delta u=\lambda |u|^p+\mu |\nabla u|^q+w(x),\quad t>0,\, x\in {\mathbb {R}}^N, \end{aligned}$$ i u t + Δ u = λ | u | p + μ | ∇ u | q + w ( x ) , t > 0 , x ∈ R N , where $$N\ge 1$$ N ≥ 1 , $$p,q>1$$ p , q > 1 , $$\lambda ,\mu \in {\mathbb {C}}$$ λ , μ ∈ C , $$\lambda \ne 0$$ λ ≠ 0 , and $$u(0,\cdot ), w\in L^1_{\mathrm{loc}}({\mathbb {R}}^N,{\mathbb {C}})$$ u ( 0 , · ) , w ∈ L loc 1 ( R N , C ) . We consider both the cases where $$\mu =0$$ μ = 0 and $$\mu \ne 0$$ μ ≠ 0 , respectively. We establish existence/nonexistence of global weak solutions. In ea…
Gården som arena for tilpasset opplæring: Erfaringer med gård–skole-tilbud i et inkluderingsperspektiv
2022
Tilpasset opplæring på gårdsbruk én eller flere dager i uken er et tilbud til enkelte elever på ungdomstrinnet som har vansker med å nyttiggjøre seg ordinær opplæring i klassen. I lys av teori om inkludering har vi undersøkt erfaringer til ansatte ved skoler og gårdbrukere som samarbeider om opplæringstilbud på gård. Det ble gjennomført 17 semistrukturerte intervju med gårdbrukere og kontaktlærere, rådgiver og skoleledere i kommunal oppvekstenhet ved fem ulike gård–skole-tilbud fra Østlandet, Vestlandet og Midt-Norge. Informantenes erfaringer ble sett i lys av Haugs (2014) teori om inkludering og Lave og Wengers (2003) teori om situerte praksisfellesskap. Informantenes erfaringer viste at r…
El mito de la identidad y sus supuestos enemigos: ficciones que marcan el trato diferenciado en la acogida de personas migrantes en Europa
2022
El desplazamiento es inherente al ser humano, ya sea en el seno de poblaciones nómadas o sedentarias, sea aquel voluntario o forzoso debido a peligros provocados por conflictos de todo tipo, a los efectos del clima, o por cualquier otro motivo. Así ha sido a lo largo de nuestra historia, una llena de migraciones continuadas que han ido configurando y que siguen dando forma a las sociedades en las que hoy nos hallamos. Ello, no obstante, se halla en tensión con el concepto de territorialidad que pretende explicar la voluntad humana de dominar el espacio, y con el motivo de pertenencia a un grupo determinado, todo lo cual motiva respuestas diferentes en el momento de acoger a las personas rec…
Chemical composition of the essential oil of Cyanus adscendens (Bartl.) Soják and C. orbelicus (Velen.) Soják growing wild in Bulgaria, and PCA analy…
2022
Cyanus Mill. genus, belonging to the Asteraceae family, includes more than 50 taxa, mainly growing in Central and Southern Europe, North Africa, Asia Minor, and the Caucasus. Previous investigations on Cyanus taxa have shown that they are rich source of flavonoids and phenolic compounds but, differently from species of genus Centaurea, almost devoid of sesquiterpene lactones. In the present study, the chemical composition of the essential oils from aerial parts of Cyanus adscendens (CA) and C. orbelicus (CO), collected in Bulgaria, and not previously investigated, was evaluated by GC-MS. The main components of CA were α-bergamotene (31.3%), (Z,Z,Z)-9,12,15-octadecatrien-1-ol (14.5%) and cal…

Anti-inflammatory properties of lemon-derived extracellular vesicles are achieved through the inhibition of ERK/NF-κB signalling pathways
2022
Chronic inflammation is associated with the occurrence of several diseases. However, the side effects of anti-inflammatory drugs prompt the identification of new therapeutic strategies. Plant-derived extracellular vesicles (PDEVs) are gaining increasing interest in the scientific community for their biological properties. We isolated PDEVs from the juice of Citrus limon L. (LEVs) and characterized their flavonoid, limonoid and lipid contents through reversed-phase high-performance liquid chromatography coupled to electrospray ionization quadrupole time-of-flight mass spectrometry (RP-HPLC-ESI-Q-TOF-MS). To investigate whether LEVs have a protective role on the inflammatory process, murine a…
Associations between physical activity, motor skills, executive functions and early numeracy in preschoolers
2022
We investigated direct and indirect cross-sectional associations of physical activity, fundamental motor skills, executive functions, and early numeracy in preschoolers. The participants were 214 preschoolers aged three to five years. Time spent in moderate and vigorous physical activity was measured by hip-worn accelerometers and fundamental motor skills using the tasks assessing locomotor, object control, and stability skills. Inhibition/switching and working memory/updating, as components of executive functions, were assessed by computerized tests and a standardized test was used to assess early numeracy. Path analyses were used to examine direct and indirect associations between the con…
Investigating teachers’ dyadic self-efficacy and its correlations to students’ perceptions of teacher efficacy and student well-being
2022
Most studies, to date, have ignored variance in teachers’ self-efficacy (TSE) in relation to teaching individual students (i.e., student-specific self-efficacy). However, TSE and teacher efficacy differ among students. Thus, this study examines dyadic TSE in four domains and their correlations with students’ perceptions of teacher efficacy and student academic self-concept and well-being. Results of a paper–pencil survey involving 29 teachers and 469 students (39.9% girls, aged 10–17 years) from German secondary schools reveal a moderate overlap between dyadic TSE and students’ perceptions of teacher efficacy. Furthermore, they reveal variance in how teachers’ and students’ ratings are rela…
Mixité, égalité et pratiques en éducation physique et sportive
2022
« Mixité, égalité et pratiques », ce triptyque pourra en apparence manquer d’originalité pour qui aurait un peu de familiarité aux travaux sur l’Éducation physique et sportive (EPS) en Sciences de l’éducation et de la formation (SEF) ou en Sciences et techniques des activités physiques et sportives (STAPS). Puisqu’il s’agit d’une indéniable ultime redite, le choix du titre de ce dossier mérite au moins deux réflexions : l’une appelle à y trouver un certain immobilisme disciplinaire, et plus largement scolaire, sur le mode « rien n’a changé, les inégalités collent à la mixité et à la différence des corps sexués » ; l’autre y voit, comme Pénélope durant l’absence d’Ulysse, un ouvrage sans ces…
Coinfection patterns of two marine apicomplexans are not associated with genetic diversity of their polychaete host.
2022
Coinfections of two or more parasites within one host are more of a rule than an exception in nature. Interactions between coinfecting parasites can greatly affect their abundance and prevalence. Characteristics of the host, such as genetic diversity, can also affect the infection dynamics of coinfecting parasites. Here we investigate for the first time the association of coinfection patterns of two marine apicomplexans, Rhytidocystis sp. and Selenidium pygospionis, with the genetic diversity of their host, the polychaete Pygospio elegans, from natural populations. Host genetic diversity was determined with seven microsatellite loci and summarized as allelic richness, inbreeding coefficient…
Magnetically excited breather modes in an overlap-geometry Josephson tunnel junction
2022
A scheme for the controlled generation of single traveling sine- Gordon breathers in a long Josephson junction is described. In the presence of dissipation, a direct current source, and thermal fluctuations, the theoretical analysis shows that, through the nonlinear supratransmission effect, tailored magnetic pulses at the junction’s edge can effectively yield breather modes only.
