Selection of Debaryomyces hansenii isolates as starters in meat products based on phenotypic virulence factors, tolerance to abiotic stress condition…
2021
Debaryomyces hansenii is a yeast widely used in meat fermentations as starter for the purpose of improving the aromatic quality of the final product. However, it has not been the subject of an extensive study regarding phenotypic characteristics important for starter selection, such as the capacity to grow at abiotic stress conditions occurring during fermentation, the ability to generate desirable aromas and the absence of virulence traits in yeasts.

LightSleepNet: A Lightweight Deep Model for Rapid Sleep Stage Classification with Spectrograms.
2021
Deep learning has achieved unprecedented success in sleep stage classification tasks, which starts to pave the way for potential real-world applications. However, due to its enormous size, deployment of deep neural networks is hindered by high cost at various aspects, such as computation power, storage, network bandwidth, power consumption, and hardware complexity. For further practical applications (e.g., wearable sleep monitoring devices), there is a need for simple and compact models. In this paper, we propose a lightweight model, namely LightSleepNet, for rapid sleep stage classification based on spectrograms. Our model is assembled by a much fewer number of model parameters compared to…

Measuring the Rate of Information Transfer in Point-Process Data: Application to Cardiovascular Interactions
2021
We present the implementation to cardiovascular variability of a method for the information-theoretic estimation of the directed interactions between event-based data. The method allows to compute the transfer entropy rate (TER) from a source to a target point process in continuous time, thus overcoming the severe limitations associated with time discretization of event-based processes. In this work, the method is evaluated on coupled cardiovascular point processes representing the heartbeat dynamics and the related peripheral pulsation, first using a physiologically-based simulation model and then studying real point-process data from healthy subjects monitored at rest and during postural …

Assessment of the Optimum Linker Tethering Site of Alternariol Haptens for Antibody Generation and Immunoassay Development
2021
Immunochemical methods for mycotoxin analysis require antigens with well-defined structures and antibodies with outstanding binding properties. Immunoreagents for the mycotoxins alternariol and/or alternariol monomethyl ether have typically been obtained with chemically uncharacterized haptens, and antigen conjugates have most likely been prepared with mixtures of functionalized molecules. For the first time, total synthesis was performed, in the present study, to obtain two haptens with opposite linker attachment locations. The functionalized synthetic haptens were purified and deeply characterized by different spectrometric methods, allowing the preparation of bioconjugates with unequivoc…
Le recours au dialogue avec les parties prenantes dans l'exercice de la responsabilité sociale des entreprises (RSE) : proposition d'une typologie
2021
Since Freeman's work (1984), dialogue with stakeholders has become a central theme in the field of Corporate Social Responsibility (CSR) (Bonnafous-Boucher & Pesqueux 2006; Brown & Dillard 2015; Brown et al. 2020).This dialogue is strongly encouraged by international standards (ISO 26000, GRI, IIRC, AA1000SES, OCDE Principles), which describe it as a tool to inform the decisions of organizations and to allow stakeholders to make their views heard.While the concept of dialogue is omnipresent in the literature, the use of dialogue as a management device is little questioned and documented in scientific studies. How is the dialogue organized by companies? What are the roles of stakeholders? In…

Towards low-energy-light-driven bistable photoswitches : ortho-fluoroaminoazobenzenes
2021
AbstractThermally stable photoswitches that are driven with low-energy light are rare, yet crucial for extending the applicability of photoresponsive molecules and materials towards, e.g., living systems. Combined ortho-fluorination and -amination couples high visible light absorptivity of o-aminoazobenzenes with the extraordinary bistability of o-fluoroazobenzenes. Herein, we report a library of easily accessible o-aminofluoroazobenzenes and establish structure–property relationships regarding spectral qualities, visible light isomerization efficiency and thermal stability of the cis-isomer with respect to the degree of o-substitution and choice of amino substituent. We rationalize the exp…

A Process-Oriented View of Procedural Memory Can Help Better Understand Tourette’s Syndrome
2021
Tourette’s syndrome (TS) is a neurodevelopmental disorder characterized by repetitive movements and vocalizations, also known as tics. The phenomenology of tics and the underlying neurobiology of the disorder have suggested that the altered functioning of the procedural memory system might contribute to its etiology. However, contrary to the robust findings of impaired procedural memory in neurodevelopmental disorders of language, results from TS have been somewhat mixed. We review the previous studies in the field and note that they have reported normal, impaired, and even enhanced procedural performance. These mixed findings may be at least partially be explained by the diversity of the s…
Textiles in blue : production, consumption and material culture in rural areas in early-nineteenth century Finland
2021
The article focuses on masculine consumption patterns and the production and dyeing of textiles in rural Finland in the early nineteenth century. It maintains that the rural consumption of textiles as well as individual choices and tastes evolved, and our selected examples of males’ wardrobes demonstrate that contemporary styles were followed. The article targets an era that can be regarded as a watershed: this was a time when mass production was in its infancy and craft production and self-sufficiency were still relevant to household economies. As the wealth of certain groups, particularly landed peasantry, increased, they began among other things to purchase and wear clothes dyed with imp…

Gross motor coordination: We have a problem! A study with the Körperkoordinations Test für Kinder in youth (6-13 Years)
2021
The main goal of our cross-sectional research was to determine the current values of gross motor coordination (GMC) of Italian boys and girls between 6 and 13 years of age. Secondary goals were to study gender differences, and the four subtests trend with ages. Results were compared with the references proposed by KTK authors and with similar searches. Anthropometric measurements and KTK data from 2,206 schoolchildren (girls: n = 1,050; boys: n = 1,156) were collected. The KTK raw score (RS) increased with the age of the subjects (r = 0.678; p < 0.001). In 11–13-year-old subjects, the increase in results is less than in younger subjects. RS showed differences by gender (F = 5.899; p …

Unconventional Aeronautical Investigatory Methods: The Case of Alitalia Flight AZ 112
2021
Viene svelato scientificamente la causa del disastro aereo di Montagna Longa del 5 maggio 1972 Based on unconventional air investigation techniques, this book highlights the mysterious crash of Alitalia flight AZ 112 on 5 May 1972, which killed 115 people, and was blamed solely on pilot negligence. Its findings show the cause of the disaster was not actually related to any pilot negligence, but, rather, it was the result of a criminal act. It argues that this attack was a symptom of the geopolitical tensions in Italy and Europe in that decade. Based on unconventional air investigation techniques, this book highlights the mysterious crash of Alitalia flight AZ 112 on 5 May 1972
An efficient functional magnetic resonance imaging data reduction strategy using neighborhood preserving embedding algorithm
2021
High dimensionality data have become common in neuroimaging fields, especially group-level functional magnetic resonance imaging (fMRI) datasets. fMRI connectivity analysis is a widely used, powerful technique for studying functional brain networks to probe underlying mechanisms of brain function and neuropsychological disorders. However, data-driven technique like independent components analysis (ICA), can yield unstable and inconsistent results, confounding the true effects of interest and hindering the understanding of brain functionality and connectivity. A key contributing factor to this instability is the information loss that occurs during fMRI data reduction. Data reduction of high …

Our research comes within the scope of Social Sciences, and more particularly within Management Sciences, since our central question concerns the professionalization of lecturers, their career path, their training practices, and their skills.Two surveys carried out among a sample of lecturers from private universities in Angola, as well as analyses of responses to closed and open questionnaires, show that human resources management concerns both lecturers and the future managers trained by them.
Early Life Influences on Hearing in Adulthood : a Systematic Review and Two-Step Individual Patient Data Meta-Analysis
2021
Objectives: Adverse prenatal and early childhood development may increase susceptibility of hearing loss in adulthood. The objective was to assess whether indices of early development are associated with adult-onset hearing loss in adults ≥18 years. Design: In a systematic review and meta-analysis, four electronic databases were searched for studies reporting associations between indices of early development (birth weight and adult height) and adult-onset hearing loss in adults ≥18 years. We screened studies, extracted data, and assessed risk of bias. Authors were contacted to provide adjusted odds ratios from a logistic regression model for relationships between birth weight/adult height a…
Pestov identities and X-ray tomography on manifolds of low regularity
2021
We prove that the geodesic X-ray transform is injective on scalar functions and (solenoidally) on one-forms on simple Riemannian manifolds $(M,g)$ with $g \in C^{1,1}$. In addition to a proof, we produce a redefinition of simplicity that is compatible with rough geometry. This $C^{1,1}$-regularity is optimal on the H\"older scale. The bulk of the article is devoted to setting up a calculus of differential and curvature operators on the unit sphere bundle atop this non-smooth structure.

Si nos adentramos en la historia de la música de occidente, pasando por los diferentes periodos históricos, las mujeres han tenido pocas oportunidades de acceder al ámbito académico musical y, posteriormente, al mundo laboral. Cuando nos referimos a la música clásica son escasos los referentes femeninos en ámbitos tales como la composición, la dirección orquestal y la interpretación en una orquesta de música clásica. El objetivo principal de este artículo es identificar cuáles son los factores que dificultan la carrera de las mujeres que se dedican profesionalmente a uno o varios de los tres ámbitos citados. Para ello, se ha partido de la situación de siglos pasados, mediante la recopilació…
Cultural Transfers and Literary Games : From the Mediaeval French Version of Fair Maguelonne to the Czech Version
2021
In the present thesis, we intend to study the novel Pierre de Provence et la belle Maguelonne and the translations thereof into German and Czech in greater depth than heretofore. For our corpus, we have chosen the Manuscript of Coburg, edited by R. Colliot, the German translation, made by Veit Warbeck in 1527 and edited by J. Bolte and a Czech edition from 1780, published again by J. Kolár.After presenting the novel, its origins, and selected translations reworkings, we devote a chapter to the definition of the term and the concept of play, because we are convinced that play is the principle on which the novel is constructed. In the third chapter, we propose an interpretation of the text of…
Biomethane Production from Anaerobic Co-Digestion of Selected Organic Fraction of Municipal Solid Waste (OFMSW) with Sewage Sludge: Effect of the Ino…
2021
The aim of this study was to evaluate the effect of the inoculum to substrate ratio (ISR) and the mixture ratio between organic fraction of municipal solid waste (OFMSW) and sewage sludge (SS) on the methane production potential achievable from anaerobic co-digestion (AcoD). Biochemical Methane Potential (BMP) assays at mesophilic temperature were used to determine the best AcoD configuration for maximizing methane yield and production rate, as well as to address possible synergistic effects. The maximum methane yield was observed at ISR of 1 and 60% OFMSW: 40% SS as co-digestion mixture, whereas the highest methane production rate was achieved at ISR of 2 with the same mixture ratio (207 m…

Achieving complete nitrification below the washout SRT with hybrid membrane aerated biofilm reactor (MABR) treating municipal wastewater
2021
This study analyzed the performances of a hybrid membrane aerated biofilm reactor (MABR) pilot plant in terms of nutrients removal of the attached growth and suspended biomass in comparison with a conventional activated sludge (CAS) system at different sludge retention time (SRT) (20−3) days. Overall, the MABR showed better performances than the CAS in terms of TSS (86% vs 79%), COD (89% vs 85%) and total nitrogen (80% vs 65%). The minimum SRT for achieving complete nitrification in the MABR was close to 3 days, corresponding to a SRT in the aerobic compartment of 1.9 days, whereas in the CAS it was equal to 8 days (aerobic SRT of 4.8 days). Nitrification rate in biofilm was on average equa…
Mikä muuttui vai muuttuiko mikään? Yli 65-vuotiaiden arki korona-aikana
2021
Koronapandemian leviämisen estämiseksi asetetut rajoitukset ovat kohdistuneet erityisesti ikäihmisiin, joille tauti on vaarallisin. Miten korona-aika rajoituksineen on näkynyt ikääntyneiden elämässä ja hyvinvoinnissa? Tutkimuksemme aineistona on 31 kesällä 2020 tehtyä puhelinhaastattelua. Korona-aika rajoituksineen oli vaikuttanut haastateltujen arkeen ja hyvinvointiin eri tavoin. Suuri osa koki arkensa muuttuneen vain vähän tai ei ollenkaan, osa taas koki hyvinvointinsa huonontuneen merkittävästi. Jotkut kokivat arkensa jopa parantuneen. Niillä, joilla arki ei ollut juuri muuttunut, elämä oli saattanut olla jo ennestään rajoittunutta huonon toimintakyvyn ja vähäisten sosiaalisten kontaktie…
Miksi muistisairaiden läheiset eivät käytä palveluja?
2021
Muistisairaita läheisiään hoivaavilla on merkittäviä tuen ja palveluiden tarpeita, joten on ristiriitaista, että he eivät välttämättä käytä saatavilla olevia palveluja. Tässä tutkimuksessa tarkastellaan syitä, joiden vuoksi läheiset eivät käytä palveluja. Tutkimuksen aineisto (n=45) kerättiin puhelinhaastatteluilla eri puolilta Suomea asuvilta läheisiltä; 25 heistä oli puolisoita ja 20 aikuisia lapsia. Haastattelut litteroitiin ja aineisto analysoitiin teoriaohjaavalla sisällönanalyysillä. Haastateltujen läheisten mukaan suurin syy olla käyttämättä palveluja on se, että sairastunut itse ei halua palveluja eikä myöskään suostu siihen, että läheiset hankkivat niitä. Toinen keskeinen syy on se…
Nonlinear Absorption and Refraction of Picosecond and Femtosecond Pulses in HgTe Quantum Dot Films
2021
We report measurements of the saturated intensities, saturable absorption, and nonlinear refraction in 70-nm thick films containing 4 nm HgTe quantum dots. We demonstrate strong nonlinear refraction and saturable absorption in the thin films using tunable picosecond and femtosecond pulses. Studies were carried out using tunable laser pulses in the range of 400–1100 nm. A significant variation of the nonlinear refraction along this spectral range was demonstrated. The maximal values of the nonlinear absorption coefficients and nonlinear refractive indices determined within the studied wavelength range were −2.4 × 10−5 cm2 W−1 (in the case of 28 ps, 700 nm probe pulses) and −3 × 10−9 cm2 W−1 …
