[The impact of the COVID-19 health crisis on the well-being of women giving birth].

Field: Health Professions (Health Sciences)

The objective of this work is to investigate the impact of COVID-19 health crisis on the psychological status in the first few days after giving birth. Three hundred and sixty women who gave birth in 2020 at Vivalia Hospital in Arlon (Belgium) responded to an objective data questionnaire as well as to the Edinburgh Postnatal Depression Scale (EPDS) self-questionnaire translated into French, a tool recognized in the aids in screening for postpartum depression. According to their due date, the patients were divided into three conditions, a control group and two experimental groups. The aim of this exploratory study was to assess the impact of social restrictions associated with COVID-19 on the well-being of women giving birth. The results show that the EPDS score in the immediate postpartum period for women who gave birth during the two waves of COVID-19 in 2020, associated with a strict limitation of visits, is lower (corresponding to less depression) than that of women who gave birth outside the COVID-19 period or during the partial deconfinement phase.
Vegetation Parameter Extraction Using Dual Baseline Polarimetric SAR Interferometry Data

Field: Earth and Planetary Sciences (Physical Sciences)

For vegetation parameter inversion, the single baseline polarimetric SAR interferometry (POLinSAR) technique, such as the three-stage method and the ESPRIT algorithm, is limited by the observed data with the minimum ground to volume amplitude ration, which effects the estimation of the effective phase center for the vegetation canopy or the surface, and thus results in the underestimated vegetation height. In order to remove this effect of the single baseline inversion techniques in some extend, another baseline POLinSAR data is added on vegetation parameter estimation in this paper, and a dual baseline POLinSAR technique for the extraction of the vegetation parameter is investigated and improved to reduce the dynamic bias for the vegetation parameter estimation. Finally, the simulated data and real data are used to validate this dual baseline technique.
Design of a High-Frequency Transformer and 1.7 kV Switching-Cells for an Integrated Power Electronics Building Block (iPEBB)

Field: Engineering (Physical Sciences)

This paper presents the design of a 250 kW integrated power electronics building block (iPEBB) for future electric ship application. This work focuses on the motivation, design choices, and initial prototyping of a 500 kHz transformer and 1.7 kV SiC switching-cells which form the core of the converter. The transformer is designed for 13.8 kVAC and utilizes electric-field-grading conductive insulation layers. Furthermore, new insulating substrate technologies and layouts are explored to meet the challenges of developing a fast switching, low inductance switching-cell. Electrical, thermal, and weight analysis for the switching-cells are explored to achieve a power loop inductance of 3.5 nH and maximum junction temperature of 175 °C. The packaging of 1.7 kV SiC MOSFET switching-cells based on these substrates is also presented. This work will help advance the development of a light-weight, fast-switching iPEBB to serve as the backbone for power distribution systems on electric ships.

Field: Agricultural and Biological Sciences (Life Sciences)

is Gypchek, a vital Pesticide for gypsy moths, but its future availability is not assured. If the private sector will not produce a safe and useful pesticide because the market is unstable, some other approach toward developing such products and making them available is needed. A federal center may be necessary to research biopesticides, transfer technology to the private sector, and develop, register, produce, and market those products that industry will not.
Transnasal Endoscopic Evaluation of Swallowing: A Bedside Technique to Evaluate Ability to Swallow Pureed Diets in Elderly Patients with Dysphagia

Field: Health Professions (Health Sciences)

BACKGROUND: Endoscopic evaluation of swallowing (EES) is not commonly used by gastroenterologists to evaluate swallowing in patients with dysphagia. OBJECTIVE: To use transnasal endoscopy to identify factors predicting successful or failed swallowing of pureed foods in elderly patients with dysphagia. METHODS: EES of pureed foods was performed by a gastroenterologist using a small-calibre transnasal endoscope. Factors related to successful versus unsuccessful swallowing of pureed foods were analyzed with regard to age, comorbid diseases, swallowing activity, saliva pooling, vallecular residues, pharyngeal residues and airway penetration/aspiration. Unsuccessful swallowing was defined in patients who could not eat pureed foods at bedside during hospitalization. Logistic regression analysis was used to identify independent predictors of swallowing of pureed foods. RESULTS: During a six-year period, 458 consecutive patients (mean age 80 years [range 39 to 97 years]) were considered for the study, including 285 (62%) men. Saliva pooling, vallecular residues, pharyngeal residues and penetration/aspiration were found in 240 (52%), 73 (16%), 226 (49%) and 232 patients (51%), respectively. Overall, 247 patients (54%) failed to swallow pureed foods. Multivariate logistic regression analysis demonstrated that the presence of pharyngeal residues (OR 6.0) and saliva pooling (OR 4.6) occurred significantly more frequently in patients who failed to swallow pureed foods. CONCLUSIONS: Pharyngeal residues and saliva pooling predicted impaired swallowing of pureed foods. Transnasal EES performed by a gastroenterologist provided a unique bedside method of assessing the ability to swallow pureed foods in elderly patients with dysphagia.
Tuning a Fully Convolutional Network for Velocity Model Estimation

Field: Computer Science (Physical Sciences)

Abstract Different parameters of a fully convolutional network (FCN) are experimented to evaluate which combination predicts sound velocity models from a single configuration of seismic modeling. The evaluation is made considering some fixed parameters of the deep learning model, such as number of epochs, batch size and loss function, but with variations of the optimizer and activation function. The considered optimizers were RMSprop, Adam and Adamax, whilst the activations functions were the Rectified Linear Unit (ReLU), Leaky ReLU, Exponential Linear Unit (ELU) and Parametric ReLU (PReLU). Five metrics were used to evaluate the model during the testing stage: R2, Pearson's r, factor of two, mean absolute error and mean squared error. To the extent of these experiments, it was found that the optimizers have much more influence than the activation functions when determining the resolution of the output model. The best combination was the one using the PReLU activation function with the Adamax optimizer.
First observation and analysis of DANCE: Dark matter Axion search with riNg Cavity Experiment

Field: Physics and Astronomy (Physical Sciences)

Dark matter Axion search with riNg Cavity Experiment (DANCE) was proposed to search for axion dark matter [Phys. Rev. Lett. 121, 161301 (2018)]. We aim to detect the rotation and oscillation of optical linear polarization caused by axion-photon coupling with a bow-tie cavity. DANCE can improve the sensitivity to axion-photon coupling constant $g_{a γ}$ for axion mass $m_a < 10^{-10}~\rm{eV}$ by several orders of magnitude compared to the best upper limits at present. A prototype experiment DANCE Act-1 is ongoing to demonstrate the feasibility of the method and to investigate technical noises. The optics was assembled and the performance of the cavity was evaluated. The first 12-day observation was successfully performed in May 2021. We reached $3 \times 10^{-6}~\rm{rad/\sqrt{Hz}}$ at $10~\rm{Hz}$ in the one-sided amplitude spectral density of the rotation angle of linear polarization.
Seasonal Morphological and Biochemical Variation of Coffea canephora Pierre ex A. Froehner (Rubiaceae) Leaves of Early, Intermediate and Late Maturing Genotypes

Field: Agricultural and Biological Sciences (Life Sciences)

Understanding the growth patterns of genotypes optimizes their selection and management. The objective of this study is to investigate the seasonal variations in the morphology and biochemistry of Coffea canephora clone leaves, considering climatic conditions and the maturation cycle. Morphological characteristics and carbohydrate contents of the leaves were analyzed throughout the growth cycle. A nonlinear logistic model was applied, and critical points of the leaf emission rates of plagiotropic branches were determined. Leaf growth was greater at higher temperatures during the rainy periods and lower at milder temperatures during the dry season. Genotype 143 exhibited the largest leaf width in spring, while 104, A1, and P2 had the largest leaf width in summer. The logistic model was suitable for describing leaf emission, with the critical points of genotype 143 being earlier, while P2 displayed a longer leaf emission cycle. The peak growth period influenced the quantities of starch and total soluble sugars in the leaves. The dormancy period showed a higher availability of reducing sugars. Pearson correlation indicated significant coefficients between temperature, precipitation, photoperiod, and foliar characteristics. The results obtained serve as a reference for future investigations, particularly in response to environmental challenges.
Graphene oxide covalently functionalized with zinc phthalocyanine for broadband optical limiting

Field: Chemistry (Physical Sciences)

A soluble graphene oxide (GO) covalently functionalized with zinc phthalocyanine (PcZn), GO-PcZn, was synthesized by an amidation reaction. The formation of an amido bond between PcZn and GO has been confirmed by x-ray photoelectron and Fourier transform infrared spectroscopy. At the same level of linear extinction coefficient, GO-PcZn exhibited much larger nonlinear optcial extinction coefficients and broadband optical limiting performance than GO at both 532 and 1064 nm, indicating a remarkable accumulation effect as a result of the covalent link between GO and PcZn.
Perspectives on the role of punctuation in Rimbaud's Illuminations

Field: Arts and Humanities (Social Sciences)

This article examines the experimental use of punctuation in Rimbaud's Illuminations. It argues that this new type of punctuation is central to Rimbaud's conception of the prose poem . His audacious and plastic idiom in the Illuminations is enriched by his imaginative and unpredictable deployment of dashes, parentheses, capitalization, exclamation marks, italics and other such features. It is very much part of his alchimie du verbe and creates a new type of scansion for his new prose poem form. Beginning with dashes, the article seeks to shoe how the tiret has a range of functions in the collection being linked to colour and sound effects, to particular types of finale and to pivotal structural moments in poems. We also find thick accumulations of dashes at moments of key visionary breakthrough. The piece then considers how parentheses and italics figure in the Illuminations as agents of reorientation and mystification enhancing the complexity and enigmatic quality of many poems. This creates a sense of depaysement as does the widespread capitalization in the collection which adds to the mystery of so many characters - Lulu, the Vampire, H. Exclamation marks are also used prolifically and at times we find an explosion of some or all of the above elements of punctuation to startling effect for the reader as in 'Barbare' and 'Nocturne vulgaire'. This deployment of punctuation is equally apparent in areas of Une Saison en enfer and Rimbaud's dynamic punctuation should be seen in the context of his desire to discover a new language to express the inexpressible.
Solid phase extraction based on magnetic graphene oxide nanocomposite and ion mobility spectrometry for determination of bupropion

Field: Chemistry (Physical Sciences)

In this paper, a solid phase extraction based on magnetic graphene oxide nanocomposite has been introduced for the quantitative extraction of bupropion. The characterization and structural studies for the nanocomposite were carried out by fourier transform infrared spectrometry, scanning electron microscopy and X–ray diffraction techniques. Ion mobility spectrometry as a sensitive, rapid and simple method was applied for the determination of bupropion. The effect of experimental parameters (including desorption solvent: type and volume, adsorbent amount, pH, temperature and time extraction, and initial solution volume) on the extraction efficiency of the proposed method was investigated. Under optimum conditions, the calibration curves were linear in the two ranges of 4–10 and 10–24 ng with coefficients of determination R2≥ 0.98. The relative standard deviation was 5% and also the limits of detection and quantification were 0.66 and 2.20 ng, respectively. The proposed method was applied for the different brand tablets with various doses of bupropion which the satisfactory quantitative results were obtained (recovery: 88.0–92.0%).
UAV Classification using Neural Networks and CAD-generated Radar Datasets

Field: Computer Science (Physical Sciences)

<p>Using micro-doppler signatures is an effective way to classify different types of UAVs, as well as other airborne objects such as birds. To generate signatures for drones, radar measurements are needed; however, these measurements are limited to the types of available drones, the radar parameters, the targets’ range, and the environments in which these measurements are conducted. In this paper, a new method for generating signature datasets is introduced. The method uses full-wave electromagnetic simulation software. Using this method, radar drones’ datasets can be generated using different types, sizes, drone materials, radar parameters, detected range, targets speed, and rotor RPM for rotary drones. A 77 GHz modeled FMCW radar is used to create dataset for classification purposes. Finally, a Convolutional Neural Network (CNN) algorithm is used to classify five types of drones. Based on the results, the classification of the drones is found to exceed 97% accuracy. </p>

Informal Institutions in the Corporate Governance System in Russia

Field: Business, Management and Accounting (Social Sciences)

The corporate governance system in Russia, having evolved through years, can be characterized by the following features: the dominant role of the concentrated ownership structure, corporate supervision relying on a combination of ownership function and company management, the significant role of the state as the owner, and the fairly marginal relevance of external market mechanisms. Those features result partly from particular legal solutions and partly from the unwritten, informal customs or patterns of behaviour of the so-called informal institutions.The article’s main thrust is to analyse selected informal institutions which were considered the most significant from the Russian corporate governance system point of view. These are, among others: the tendency not to obey the rights of minority shareholders, informal relationships of enterprises with authorities of various levels, and corruption. The author assumes that informal institutions decide upon the specificity of the corporate governance system in Russia and its particular elements, and upon the efficient functioning of supervisory mechanisms.

Assessment of Heat Resistance of Bacterial Spores from Food Product Isolates by Fluorescence Monitoring of Dipicolinic Acid Release

Field: Agricultural and Biological Sciences (Life Sciences)

ABSTRACT This study is aimed at the development and application of a convenient and rapid optical assay to monitor the wet-heat resistance of bacterial endospores occurring in food samples. We tested the feasibility of measuring the release of the abundant spore component dipicolinic acid (DPA) as a probe for heat inactivation. Spores were isolated from the laboratory type strain Bacillus subtilis 168 and from two food product isolates, Bacillus subtilis A163 and Bacillus sporothermodurans IC4. Spores from the lab strain appeared much less heat resistant than those from the two food product isolates. The decimal reduction times ( D values) for spores from strains 168, A163, and IC4 recovered on Trypticase soy agar were 1.4, 0.7, and 0.3 min at 105°C, 120°C, and 131°C, respectively. The estimated Z values were 6.3°C, 6.1°C, and 9.7°C, respectively. The extent of DPA release from the three spore crops was monitored as a function of incubation time and temperature. DPA concentrations were determined by measuring the emission at 545 nm of the fluorescent terbium-DPA complex in a microtiter plate fluorometer. We defined spore heat resistance as the critical DPA release temperature ( T c ), the temperature at which half the DPA content has been released within a fixed incubation time. We found T c values for spores from Bacillus strains 168, A163, and IC4 of 108°C, 121°C, and 131°C, respectively. On the basis of these observations, we developed a quantitative model that describes the time and temperature dependence of the experimentally determined extent of DPA release and spore inactivation. The model predicts a DPA release rate profile for each inactivated spore. In addition, it uncovers remarkable differences in the values for the temperature dependence parameters for the rate of spore inactivation, DPA release duration, and DPA release delay.
Diagnosis of cerebral toxoplasmosis by a nested polymerase chain reaction: a case report.

Field: Medicine (Health Sciences)

A 24-year-old man infected with human immunodeficiency virus type I rapidly progressed to acquired immune deficiency syndrome. His clinical picture was compatible with a presumptive diagnosis of cerebral toxoplasmosis. Application of a nested polymerase chain reaction (PCR) succeeded in detecting Toxoplasma gondii DNA in both the venous blood and cerebrospinal fluid specimens. This result indicates that PCR is a convenient tool for making a rapid and accurate diagnosis of cerebral toxoplasmosis, especially in developing countries.
Portable Data Management Cloud for Field Science

Field: Computer Science (Physical Sciences)

A modern field science such as archaeology is heavily data-driven using various kinds of state-of-the-art measurement instruments. It requires sophisticated computer infrastructure to manage large amounts of heterogeneous data. The concept of cloud computing provides a flexible cyber infrastructure for large-scale data management, which is being deployed at university campuses. A problem unique to field research is that researchers often work at remote field sites with limited computer and network resources. For a data management system that has to work in the campus cloud and under vastly different field conditions, portability of computer infrastructure and common data access methods are essential requirements. This paper explores the portability of cloud infrastructure and illustrates the portable data management system that we used in a recent archaeological expedition.
Nationalist Erosion after Protest and Repression

Field: Social Sciences (Social Sciences)

Abstract The leaders of authoritarian regimes often invoke nationalist themes to garner support from their populations. However, negative experiences with the regime may effectively inoculate individuals against nationalist campaigns, reducing the ability of the regime to sway public opinion. In this paper, we study the long-term effects of mobilization and repression on nationalist attitudes. We exploit a discontinuity in exposure to a student movement, by comparing alumni who were in college and on campus during the movement with alumni who only enrolled after the movement was suppressed. We find that alumni who were in college during the movement are substantially less nationalistic than those who enrolled shortly thereafter. Our findings are consistent across a range of specifications and show that exposure to mass mobilization and state repression is associated with lower support for nationalism. These differences are observable more than twenty-five years later, despite sustained state censorship.
