Personal and Environmental Risk Factors at Birth and Hospital Admission: Direct and Vitamin D-Mediated Effects on Bronchiolitis Hospitalization
2021
Abstract: Seasonal variations in UV-B radiation may influence vitamin D status, and this, in turn, may influence the risk of bronchiolitis hospitalization. The aim of this study was using a causal inference approach to investigate, simultaneously, the interrelationships between personal and environmental risk factors at birth/hospital admission (RFBH), serum vitamin D levels and bronchiolitis hospitalization. A total of 63 children (<2 years old) hospitalized for bronchiolitis (34 RSV-positive) and 63 controls were consecutively enrolled (2014-2016). Vitamin D levels and some RFBH (birth season, birth weight, gestational age, gender, age, weight, hospitalization season) were recorded. The d…
Estudio de la diseminación de elementos genéticos móviles en la microbiota intestinal
2021
La multirresistencia a antibióticos en patógenos bacterianos, incluyendo enterobacterias y enterococo, está catalogada por la OMS como uno de los 3 principales problemas de salud a nivel mundial del siglo XXI. La adquisición de nuevas resistencias está altamente relacionada con la diseminación de plásmidos conjugativos y otros elementos genéticos móviles (EGM) que codifican genes que confieren resistencia a antibióticos. Las características específicas del ambiente intestinal, entre las que destaca la elevada densidad bacteriana que permite el contacto directo entre bacterias filogenéticamente alejadas, convierten al intestino en un nicho muy favorable para la diseminación de EGM y por tant…
Un concetto di suolo per valorizzare i servizi ecosistemici nell’economia del dopo Covid 19
2021
Changes in land use and soil management and the introduction of new technologies which exploiting environmental resources have in many cases led to an increase in soil degradation. A new definition of soil could be useful because it could lead to the genesis of a new discipline that we could call pedo-economics.

It allows the possibility of integrating materials with different physical and chemical properties to widen the range of practical applications. In this context, Au NPs have recently attracted a lot of attention due to the great opportu…
Dual-task conditions on static postural control in older adults: A systematic review and meta-analysis
2021
Dual-task (DT) consists of the performance of two tasks simultaneously. An index of DT difficulty has been linked to decreased postural control. Because a wide range of DT is employed, this study aimed to evaluate its effects in static balance in older adults. PubMed, Web of Science, and Scopus were screened, and the secondary tasks were grouped as manual, reaction time, discrimination and decision making, mental tracking, verbal fluency, working memory, or “other” tasks. A total of 66 studies have been included. The meta-analysis was conducted on 28 effects and showed a significant mean effect size of d = 0.24 (p = .02, SE = 0.10; confidence interval [0.04, 0.44]), indicating a worsening i…

Surface Plasmons for Chiral Sensing
2021
Chiral sensitive techniques have been used to probe the fundamental symmetries of the universe, study biomolecular structures, and even develop safe drugs. The traditional method for the measurement of chirality is through optical activity, however, chiroptical signals are inherently weak and often suppressed by large backgrounds. Different techniques have been proposed to overcome the limitations of traditionally used optical polarimetry, such as cavity- and/or nanophotonic-based schemes. In this chapter we demonstrate how surface plasmon resonance can be employed as a new research tool for chiral sensing, which we term here as CHIral Surface Plasmon Resonance (CHISPR). We present how surf…
The Evolution and Trends of Eurosceptic Success
2021
The evolution of Euroscepticism in the countries of Western Europe has not had a linear character—parties of various ideologies and political colour have taken up the mantle of Euroscepticism over the years, while their success has risen and waned. While the aim here is to provide nomothetic, ceteris paribus results that provide an overview of Eurosceptic Contagion at the level Western Europe as a whole (and makes the argument that the shift in policy positions is an EU15 wide phenomenon), it is important to see how the fate of Eurosceptic Parties has risen and declined at various times in individual, discrete countries. A simple glance at this more descriptive data reveals various interest…

Vehicle localization based on scene perception
2021
The vision-based vehicle localization task is tackled as an image-based place recognition problem in this thesis. As image representation is an important process to place recognition, we proposed place recognition methods focusing on increasing the quality of image features. First, the dynamic object removal step is proposed to remove the dynamic objects, such as vehicles and pedestrians, of an image by semantic segmentation method and restore their background information by image inpainting method. Second, reducing instead of removing the noisy information of an image is proposed. Using the image blurring method to reduce the image noise, the performance of place recognition is improved wi…
Impacto de la inmunosupresión y otros factores de riesgo en el desarrollo de infecciones en pacientes con enfermedad inflamatoria intestinal: estudio…
2021
Antecedentes: Las complicaciones infecciosas se asocian con una mortalidad y una morbilidad significativas en los pacientes con enfermedad inflamatoria intestinal (EII). La terapia inmunosupresora se ha considerado como el principal factor de riesgo para su desarrollo, especialmente cuando se asocian dos o más inmunomoduladores. Sin embargo, los resultados disponibles provienen de estudios heterogéneos en los que no siempre queda bien definida la intensidad de esta asociación, su interacción con otros factores de riesgo ni el tipo de población al que pueden extrapolarse las conclusiones. Objetivo: 1) Identificar qué factores de riesgo se asocian al desarrollo de infecciones en EII y cuantif…

Differential constraints for iteratively generated curves
2021
Roughness is a complex concept, that is multiscale, and based on the study of the local behavior of a curve or a surface in a given neighborhood. A large number of conventional statistical parameters are currently available to attempt to appreciate this concept in the different application areas that make use of it. But it is often difficult, for a given application domain or a special need, to know precisely which parameter(s) connect(s) the topography of a surface to the physical phenomena that it undergoes. We believe that a geometric characterization should be more suitable. We suggest to control roughness by exploiting the differential behavior of curves and surfaces. We are interested…

Boolean Networks: A Primer
2021
Abstract Autism Spectrum Disorders (ASDs) stand out as a relevant example where omics-data approaches have been extensively and successfully employed. For instance, an outstanding outcome of the Autism Genome Project relies in the identification of biomarkers and the mapping of biological processes potentially implicated in ASDs’ pathogenesis. Several of these mapped processes are related to molecular and cellular events (e.g., synaptogenesis and synapse function, axon growth and guidance, etc.) that are required for the development of a correct neuronal connectivity. Interestingly, these data are consistent with results of brain imaging studies of some patients. Despite these remarkable pr…
Conditions d'hydrolyse au cours du Lutétien-Bartonien dans le Bassin parisien : apport des forages d'Ussy-sur-Marne et du Tillet
2021
L’évolution des conditions climatiques du Paléogène a donné lieu à plusieurs synthèses régionales et globales. Le Bassin parisien, qui est l’un des bassins historiques pour la connaissance des dépôts cénozoïques, a été paradoxalement peu étudié du point de vue des paléoclimats. Cela s’explique par des affleurements dispersés, combinés à une grande variation des environnements de dépôts alternant entre continental et marin ouvert, et un calage stratigraphique complexe. Si les reconstitutions de températures sont accessibles par les données floro-faunistiques et isotopiques (δ18O), l’évolution des conditions hydriques et leurs conséquences sur la production et le transport des sédiments terri…
Controlling the formation of sodium/black phosphorus intercalated compounds towards high sodium content
2021
The solid-state synthesis of pure sodium-black phosphorus intercalation compounds (Na-BPICs) has been optimized in bulk for two stoichiometric ratios. Specifically, in-situ X-Ray diffraction (XRD) allowed the precise identification of the optimal temperature range for the formation of Na-BPICs: 94 °C–96 °C. Moreover, as the undesired formation of Na3P takes place at this very same range, we succeeded in introducing a new synthetic route based on a fast-thermal ball milling implementation that results in the bulk production of BPIC without Na3P in 9 out of 10 cases. Finally, by combining XRD, Raman spectroscopy, and DFT calculations we developed a new structural model for Na-based BPICs show…

The time course of processing handwritten words: An ERP investigation
2021
Available online 25 June 2021. Behavioral studies have shown that the legibility of handwritten script hinders visual word recognition. Furthermore, when compared with printed words, lexical effects (e.g., word-frequency effect) are magnified for less intelligible (difficult) handwriting (Barnhart and Goldinger, 2010; Perea et al., 2016). This boost has been interpreted in terms of greater influence of top-down mechanisms during visual word recognition. In the present experiment, we registered the participants’ ERPs to uncover top-down processing effects on early perceptual encoding. Participants’ behavioral and EEG responses were recorded to high- and low-frequency words that varied in scr…

2021
Abstract The influence of the degree and the way of incorporation of multi-alkenylsilsesquioxane into the polymer chain on morphological, rheological and dynamic mechanical parameters were determined. It was found that POSS incorporated into the polymer chain was located outside the crystalline structure of lamella in amorphous phase. The incorporation of POSS-6-2 as a pendant group resulted in significant increase of separation of macromolecules. The key factor in rheological and dynamic mechanical behavior of copolymers turned out to be the way of POSS incorporation into the polymer chain. The incorporation of POSS into the polymer chain as a pendant group resulted in decreased relaxation…

The influence of mechanical stresses/strains on the surface reactivity of metallic alloys is described here. The electrochemical behavior and the corrosion resistance of engineering alloys are discussed in the presence of compressive and tensile stresses through different examples. The role of physical (formation of steps, roughness, microcracks), metallurgical (dislocations, crystallographic texture, and grain size), and chemical (passive film composition) changes induced by plastic deformation on electrochemical behavior and corrosion …
Flexible negotiation process to adhere to human preferences; A case of work equipment risk assessment
2021
Making structured and reliable decisions on relevant business problems often requires expert assistance. In decision making practice, experts are frequently required to pairwise compare elements to support the decision made. This paper proposes a user-friendly negotiation procedure to establish an effective feedback relation with experts to globally increase the consistency of their pairwise comparisons judgments, where necessary. To this aim, we develop a flexible tool, which makes use of an algebraic consistency-improving algorithm and a sensitivity analysis technique to identify which judgments contribute most to inconsistency. The framework pursues friendliness for the involved decision…
