Authors: Dou Zhenhai , Wang Yajing , Li Zhenmei , Sun Xianming , Wei Qinqin , Chen Wengang
Published: February 2023

Aiming at the teaching difficulties of signal and system course, adapting to the new situation of the information age and the engineering education of outcome-based education (OBE), adhering to the traditional classroom teaching and making full use of the network teaching platform and internet technology, a blended teaching mode of internet-engineering education (BTM-IEE) is proposed. In this mode, we adhered to the educational concept of OBE, formulated teaching objectives, optimized teaching content, and built matching teaching resources. In three teaching stages: before class, in class and after class, online-offline blended teaching was effectively organized and implemented by using internet technology, network teaching platform, independently developed a comprehensive experimental system, remote virtual experiment platform, QQ group, etc. In order to ensure a good cycle of teaching quality, a multi-dimensional evaluation system is constructed. A variety of application examples and questionnaire data showed that BTM-IEE can achieve a deep integration of in class-out of class and online-offline, improve students’ engineering application ability, autonomous learning ability, cooperation, communication ability, and cultivate innovative thinking. The horizontal and vertical comparison between the traditional and the improved teaching mode shows that the BTM-IEE can improve the teaching effect, the excellent rate is significantly increased, and the failure rate is significantly reduced. This mode provides a reference for the improvement of the teaching quality of professional courses and has important practical significance.

Aim: One single nucleotide polymorphism (SNP) rs738409 in the patatin-like phospholipase domain-containing protein 3 (PNPLA3) gene has been considered a major genetic risk factor of nonalcoholic fatty liver disease (NAFLD). Data have indicated that NAFLD is related to insulin resistance and dyslipidemia, but whether rs738409 is associated with circulating lipid and lipoproteins is not fully elucidated. The main aim of this study was to assess the association of rs738409 with lipid and lipoprotein levels in patients with dyslipidemia.
Methods: This was a post-hoc analysis of a study in patients with dyslipidemia recruited on an outpatient basis. Morning blood samples were collected after a 12-h fast. Genomic DNA was extracted from whole-blood samples.
Results: One hundred seventy-five patients with dyslipidemia were included (97 women). Lipid levels [total cholesterol (TC), triglycerides (TGs), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C)] or glycosylated hemoglobin (HbA1c) were not associated with the SNP, even after adjustment for gender, body mass index (BMI) and type 2 diabetes mellitus (T2DM), using either the additive (CC vs. CG vs. GG) or the dominant (CC vs. GG + CG) inheritance model. When data were stratified for obesity, significant associations between the variant and TC (P = 0.014) or LDL-C levels (P = 0.046) in the non-obese were observed. Pairwise comparison revealed significant changes only in TC between CC and CG genotypes (P = 0.012).
Conclusions: No association was shown between rs738409 SNP and lipid/lipoprotein levels in patients with dyslipidemia. In subgroup analysis, TC was higher in non-obese, but not in obese, patients with CC, compared to CG carriers.

Published: February 2023

The primary method of showing contrast in spoken speech, according to the text, is through the use of antonyms. In antonymic relationships, polysemantic words that originated with this potential future meaning and may have an associated antonym may do so. By contrast, the semantics of various words can be determined by the meaning of a single word. The writers of the article demonstrated the reliance of derivative words of other parts of speech as well as the combination of antonyms generated by the method of word formation on the basis of antonyms.

THE NEW EDUCATION POLICY AND THE SIGNIFICANCE OF UNIVERSITY INDUSTRY LINKAGE
Authors: Ganesh C. , L Rajeeve
Published: February 2023

In a rapidly changing world, where innovative solutions fuel the engine of economic growth, the University-Industry Linkage (UIL) get wider acceptance. Effective measures for improving the University-Industry Linkage (UIL) in the country are extremely essential for addressing scientific, economic, social as well as global issues. The importance of NEP-2020 needs to be assessed in the context of industrial development and the employment opportunities it creates. The new National Education Policy-2020 pays more attention to UIL and provides a great opportunity to transform the country. University-Industry Linkages are increasingly important for innovations and crucial for scaling up the economy. Academic research is more likely to have a positive impact and be beneficial if university researchers visit the industry and interact with industrial personnel for a better outcome that addresses the needs of the industry. This conceptual paper explores the significance of UIL in the backdrop of the National Education Policy-2020. It exposes various aspects in details for improving the overall ecosystem of collaborations between the two stakeholders. The study suggests that the government should create a common platform to facilitate the relationship between the university and academia to foster new relationships and forge new ties and alliances and explore funding provisions, including public-private partnerships, to address the shortcomings.

OED and the dictionary of the world defines a "doctor" 700 years ago and today as a "teacher". The root word for the word doctor derives from Latin "docere", which means "to teach". The doctor contributes to educating patients about a number of medical conditions (the patient is experiencing a number of diseases). In essence, the doctor has the role as a teacher. Doctor-patient interaction works on relational models. The physician-trainer paradigm is required to be introduced to improve patient status. The physician-trainer model is a participatory model that results in achieving the patient's well-being and improving his/her health; the physician uses his or her capacity as a trainer, that is, he has the ability to form and instill adequate conduct for each patient. In this paper, besides highlighting the appetence for the relationship between the trainer and the patient, we tried to quantify the patient's acceptance of the treatment with/without continuous monitoring of the disease (chronic diseases), the degree of reasonableness in accepting the therapeutic behavior, and lastly how the individual feels the change of his status in the patient. The study was conducted on a total of 217 subjects (125 female subjects and 92 male subjects). The applied questionnaire contained 18 questions, structured to help us confirm or not the study's objectives. The results obtained will show us the level of appetite for the trainer-patient relationship.

The Dark Energy Spectroscopic Instrument (DESI) will precisely constrain cosmic expansion and the growth of structure by collecting ∼40 million extragalactic redshifts across ∼80% of cosmic history and one-third of the sky. The Emission Line galaxy (ELG) sample, which will comprise about one-third of all DESI tracers, will be used to probe the universe over the 0.6 < z < 1.6 range, including the 1.1 < z < 1.6 range, which is expected to provide the tightest constraints. We present the target selection for the DESI Survey Validation (SV) and Main Survey ELG samples, which relies on the imaging of the Legacy Surveys. The Main ELG selection consists of a g-band magnitude cut and a (g − r) versus (r − z) color box, while the SV selection explores extensions of the Main selection boundaries. The Main ELG sample is composed of two disjoint subsamples, which have target densities of about 1940 deg−2 and 460 deg−2, respectively. We first characterize their photometric properties and density variations across the footprint. We then analyze the DESI spectroscopic data that have been obtained from 2020 December to 2021 December in the SV and Main Survey. We establish a preliminary criterion for selecting reliable redshifts, based on the [O ii] flux measurement, and assess its performance. Using this criterion, we are able to present the spectroscopic efficiency of the Main ELG selection, along with its redshift distribution. We thus demonstrate that the Main selection 1940 deg−2 subsample alone should provide 400 deg−2 and 460 deg−2 reliable redshifts in the 0.6 < z < 1.1 and the 1.1 < z < 1.6 ranges, respectively.
Planetary Orbit Eccentricity Trends (POET). I. The Eccentricity–Metallicity Trend for Small Planets Revealed by the LAMOST–Gaia–Kepler Sample

Published: February 2023

Orbital eccentricity is one of the basic planetary properties, whose distribution may shed light on the history of planet formation and evolution. Here, in a series of works on Planetary Orbit Eccentricity Trends (dubbed POET), we study the distribution of planetary eccentricities and their dependence on stellar/planetary properties. In this paper, the first work of the POET series, we investigate whether and how the eccentricities of small planets depend on stellar metallicities (e.g., [Fe/H]). Previous studies on giant planets have found a significant correlation between planetary eccentricities and their host metallicities. Nevertheless, whether such a correlation exists for small planets (e.g., super-Earths and sub-Neptunes) remains unclear. Here, benefiting from the large and homogeneous LAMOST–Gaia–Kepler sample, we characterize the eccentricity distributions of 244 (286) small planets in single (multiple) transiting systems with the TDR method. We confirm the eccentricity–metallicity trend whereby the eccentricities of single small planets increase with stellar metallicities. Interestingly, a similar trend between eccentricity and metallicity is also found in the radial velocity sample. We also found that the mutual inclination of multiple transiting systems increases with metallicity, which predicts a moderate eccentricity–metallicity rising trend. Our results of the correlation between eccentricity (inclination) and metallicity for small planets support the core accretion model for planet formation, and they could be footprints of self (and/or external) excitation processes during the history of planet formation and evolution.

Published: February 2023

The remnant phase of a radio galaxy is characterized by the cessation of active galactic nuclei activity, resulting in the jets ceasing to feed plasma to the radio lobes. In this paper, we present a search for and the characterization of remnant candidates in a 12.5 deg2 area of the XMM-Newton Large-Scale Structure field, using deep radio observations at 325 MHz from the Giant Meterwave Radio Telescope, at 150 MHz from the LOw Frequency ARray, at 1.4 GHz from the Jansky Very Large Array (VLA), and at 3 GHz from the VLA Sky Survey. By using both morphological criteria, i.e., undetected radio core as well as spectral criteria, i.e., high spectral curvature and ultra-steep spectrum, we identify 21 remnant candidates that are found to reside mostly in non-cluster environments, and exhibit diverse properties in terms of morphology, spectral index (

in the range of −1.71 to −0.75 with a median of −1.10), and linear radio size (ranging from 242 kpc–1.3 Mpc with a median of 469 kpc). Our study attempts to identify remnant candidates down to the flux density limit of 6.0 mJy at 325 MHz, and yields an upper limit on the remnant fraction (f
rem) to be around 5%. The observed f
rem seems consistent with the predictions of an evolutionary model assuming power-law distributions of the duration of the active phase and jet kinetic power with an index of −0.8 to −1.2.

Published: February 2023

The Lyman continuum (LyC; <911.12 Å) forms at the top of the chromosphere in the quiet Sun, making LyC a powerful tool for probing the chromospheric plasma during solar flares. To understand the effects of nonthermal energy deposition in the chromosphere during flares, we analyzed LyC profiles from a grid of field-aligned radiative-hydrodynamic models generated using the RADYN code as part of the F-CHROMA project. The spectral response of LyC, the temporal evolution of the departure coefficient of hydrogen, b
1, and the color temperature, T

c
, in response to a range of nonthermal electron distribution functions, were investigated. The LyC intensity was seen to increase by 4–5.5 orders of magnitude during solar flares, responding most strongly to the nonthermal electron flux of the beam. Generally, b
1 decreased from 102–103 to closer to unity during solar flares, indicating a stronger coupling to local conditions, while T

c
increased from 8–9 to 10–16 kK. T

c
was found to be approximately equal to the electron temperature of the plasma when b
1 was at a minimum. Both optically thick and optically thin components of LyC were found to be in agreement with the interpretation of recent observations. The optically thick layer forms deeper in the chromosphere during a flare compared to quiescent periods, whereas the optically thin layers form at higher altitudes due to chromospheric evaporation, in low-temperature, high-density regions propagating upward. We put these results in the context of current and future missions.
Magnetic Reconnection in the Wakes of Cosmic Strings
Authors: Kumar Dilip , Sanyal Soma
Published: February 2023

The motion of cosmic strings in the universe leads to the generation of wakes behind them. We study magnetized wakes of cosmic strings moving in the postrecombination plasma. We show that magnetic reconnection can occur in the postshock region. Since the width of the cosmic-string wake is very small, the reconnection occurs over a very short length scale. The reconnection leads to a large amount of kinetic energy being released in the postshock region of the cosmic-string wake. This enhances the kinetic energy released during the reconnection. We make a rudimentary estimate of the kinetic energy released by the magnetic reconnection in cosmic-string wakes and show that it can account for low-energy gamma-ray bursts in the postrecombination era.

Direct PCR meets high-throughput sequencing - metabarcoding of aquatic insect communities without DNA purification
Authors: Röder Nina , Schwenk Klaus
Published: February 2023

Aquatic emergent insect communities form an important link between aquatic and terrestrial ecosystems, yet studying them is costly and time-consuming as they are usually diverse and superabundant. Metabarcoding is a valuable tool to investigate arthropod community compositions, however high-throughput applications, such as for biomonitoring, require cost-effective and user-friendly procedures. To investigate if the time-consuming and labour-intensive DNA purification step can be omitted in metabarcoding, we studied the difference in detection rates and individual read abundance using standard DNA purification versus direct PCR protocols. Metabarcoding with and without DNA purification was performed with artificially created communities of known composition as well as on natural communities both of the dipteran family Chironomidae to compare detection rates, individual read abundances and presence-absence community composition. We found that the here presented novel approach of direct PCR metabarcoding did not alter detection rates and had a minor effect on individual read abundances in artificially created communities. Furthermore, presence-absence community compositions of natural chironomid communities were highly comparable using both approaches. In conclusion, we showed that direct PCR protocols can be applied in chironomid metabarcoding approaches, with possible application for a wider range of arthropod taxa, enabling us to study communities more efficiently in the future.
Nurses with Disability: Transforming Healthcare for All
Authors: Marks Beth , Sisirak Jasmina
Published: February 2023

Disability is a natural part of the human experience and nurses with disability add greatly needed value as our colleagues. People with disability represent the largest marginalized group, making up more than 15% of the global population. Recognizing the value of nurses with disability requires an understanding of the ongoing systematic exclusion of students with disability entering the nursing profession and nurses with disability maintaining employment. Nurses with disability can offer patient-provider concordance, supporting a shared experience, valuing disability, and modeling positive expectations. In this article, we first discuss disability, ableism, and nursing. Also included is information about universal design structures for access that can be useful to support students and nurses with disability in academic and clinical settings. Lastly, we provide recommendations for nursing education and practice to include and value people with disability in these environments. Because systemic barriers can be easy to fix but often ignored, employing nurses with disability who directly experience these barriers provides an opportunity and incentive to advocate for change. Nurses with disability have enormous potential to expand healthcare from a medicalized view of disability as an inherently negative trait to a marker of diversity and the hallmark of equitable care.
Faculty Scholarship Addressing Health Disparities with Persons with Intellectual and Developmental Disabilities: A Case Study Based on Boyer’s Model of Scholarship
Authors: Ailey Sarah , Friese Tanya
Published: February 2023

Approximately seven million Americans with intellectual and developmental disabilities (IDD) face disparities and inequities in health, access to healthcare, and health outcomes. Contributing to the health disparities that face people with IDD is the lack of preparation of healthcare professionals related to their care and the lack of attention to research and quality improvement to address their unique disparities. This article describes a case study in which two faculty developed a program of scholarship, often in collaboration with graduate students in nursing and other health professions, which addresses promotion of health equity and social justice in general and specifically in the health disparities facing people with IDD. The program of scholarship is based on Boyer’s Model of Scholarship. The description of our work considers application of Boyer’s model to IDD scholarship in the context of discovery, teaching application, quality improvement across spheres of care , and integration. We offer a summary of the outcomes of our work that demonstrates impact at micro-, miso, and macro systems levels and conclude with implications for developing nursing scholarship.
Après un demi-siècle, l’économie informelle reste un concept heuristique et un ensemble flou
Authors: Charmes Jacques , Adair Philippe
Published: February 2023

50 ans de recherche suggèrent que le concept d’économie informelle constitue un ensemble flou. Les diverses théories, dualisme, structuralisme et institutionnalisme n’identifient pas les mêmes causes de l’informalité, ni les mêmes mécanismes d’ajustement sur les marchés. La définition toujours plus large de l’économie informelle, cependant distincte de l’économie non-observée, demeure tributaire de la genèse de ses différentes mesures : unité de production ou emploi ? Les trends et les cycles relatifs à l’économie informelle permettent d’établir des faits stylisés. Les enjeux et les résultats de la formalisation de l’économie informelle sont illustrés par le cas l’Afrique du Nord. Classification JEL : E26, J46, O17

Les expérimentations à l’épreuve du temps : consécration et controverse
Authors: Bédécarrats Florent , Guérin Isabelle , Roubaud François
Published: February 2023

Depuis deux décennies, les débats académiques vont croissant quant à la validité et à l’utilité des évaluations par assignation aléatoire dans le champ du développement. Cet article s’appuie notamment sur la parution récente par les auteurs d’un ouvrage de synthèse croisant les analyses des principaux protagonistes de cette controverse scientifique. Il souligne les principales lignes de force qui partagent tenants et détracteurs de la méthode expérimentale : divergences épistémologiques et méthodologiques, mais aussi sur la signification même du développement et la responsabilité éthique des chercheurs à l’égard des personnes qu’ils étudient.

Quelle économie écologique pour les Suds ?
Authors: Froger Géraldine
Published: February 2023

Cet article a pour objectif d’étudier l’économie écologique avec ses diverses tendances. Dans ce cadre, le focus est mis sur la « socio-économie écologique » qui entend s’appuyer sur une économie politique et institutionnelle hétérodoxe en soutenabilité forte. Il s’agit également de montrer les apports de la « socio-économie écologique » quant à l’analyse d’un dispositif contemporain de politique environnementale que sont les « paiements pour services environnementaux » (PSE) dans les pays des Suds.

Travail du politique et reproduction sociale des familles, de l’État et du capitalisme
Authors: Guérin Isabelle , Haritas Kaveri , Karunakaran Kalpana
Published: February 2023

Cet article propose le concept de « travail du politique » pour rendre compte du rôle actif et quotidien de nombreuses femmes de milieux populaires dans la redevabilité de l’État. Le travail du politique apparait comme une forme spécifique de travail non rémunéré, invisibilisé et féminisé car considéré comme une extension du travail domestique. Il joue pourtant un rôle majeur dans la reproduction sociale des familles, de l’État et du capitalisme et des inégalités sociales qui en forment la trame. L’article se base sur l’Inde, tout en élargissant en conclusion à d’autres contextes, suggérant que l’Inde n’est pas une exception. Classification JEL : B54, 018, P00, Z1
An assessment of the impact of targeted interventions in mitigating the adverse drivers of irregular migration and forced displacement
Authors: Beine Michel , Khoudour David , Tarvainen Johannes
Published: February 2023

Cet article discute de la manière dont les interventions publiques au nveau local ou sectoriel peuvent affecter la migration et le déplacement humain forcé. Il analyse l’évaluation empirique concernant l’impact des interventions ciblées sur la propension à émigrer, soit par choix, soit de manière forcée. La littérature académique sur les conséquences des interventions publiques locales ou sectorielles sur le comportement des individus en termes de mobilité humaine reste assez éparse et de nouvelles approches s’avèrent nécessaires pour appréhender de manière plus appropriée les différents canaux de transmission. L’article propose dès lors plusieurs pistes de recherche potentielles et d’options méthodologiques afin d’acquérir une meilleure compréhension de la manière dont les interventions publiques spécifiques peuvent atténuer les effets des conditions défavorables favorisant la migration illégale et le déplacement humain forcé.
La négociation du télétravail : dynamique, variété et fragilité
Authors: Giotto Timo , Thoemmes Jens
Published: February 2023

Cet article présente une recherche sur la négociation collective du télétravail lors de la pandémie de Covid-19. Sept études de cas avec 60 entretiens dans des entreprises de secteurs et tailles différenciées montrent la diversité de la mise en place du télétravail. Les principaux résultats indiquent une culture d’entreprise réfractaire au distanciel, une progression importante du thème dans chaque entreprise, des négociations difficiles sur l’arbitrage distanciel/présentiel. La négociation est tributaire de la variabilité des types d’entreprise. Les règles paraissent particulièrement fragiles. Elles sont adaptées en fonction de la situation sanitaire et des retours d’expérience. La négociation est permanente, décomposée en phases et ponctuée par des accords et avenants. Le thème du télétravail en pleine expansion amène des questions sur l’avenir de la négociation collective.

Safer and more effective cow milk (CM)-oral immunotherapy that does not induce allergic reactions has not yet been standardised. We sought to explore the efficacy and feasibility of a combination of heat-killed Lactiplantibacillus plantarum YIT 0132 (LP0132) and oral immunotherapy for treating IgE-mediated cow milk allergy (CMA). We conducted a 24-week, double-blind, randomised (1:1), two-arm, parallel-group, placebo-controlled, phase 2 trial of LP0132 intervention for treating IgE-mediated CMA in children aged 1-18 years (n=60) from January 29, 2018 to July 12, 2019 in Tokyo, Japan. Participants were randomly assigned to the LP0132 group receiving citrus juice fermented with LP0132 or to the control group receiving citrus juice without. Both groups received low-dose slow oral immunotherapy with CM. The primary outcome was improved tolerance to CM, proven by the CM challenge test at 24 weeks. Secondary outcomes were changes in serum biomarkers of serum-specific β-lactoglobulin-IgE (sIgE) and β-lactoglobulin-IgG4 (sIgG4). Exploratory outcomes included changes in serum cytokine levels and gut microbiota composition. A total of 61 participants were included. Finally, 31 children were assigned to the LP0132 group and 30 to the control group, respectively. After the intervention, 41.4 and 37.9% of the participants in the LP0132 and control groups, respectively, showed improved tolerance to CM. In serum biomarkers after the intervention, the sIgG4 level was significantly higher, and interleukin (IL)-5 and IL-9 were significantly lower, in the LP0132 group than in the control group. In the gut microbiome, the α-diversity and Lachnospiraceae increased significantly in the LP0132 group, and Lachnospiraceae after the intervention was significantly higher in the LP0132 group than in the control group. In conclusion, low-dose oral immunotherapy with modulating gut microbiota might be a safer and more effective approach for treating cow’s milk allergy.
Improved cloud storage auditing scheme with deduplication
Authors: Zhang Jindan , Ogiela Urszula , Taniar David , Nedjah Nadia
Published: February 2023

Cloud storage has become a crucial service for many users who deal with big data. The auditing scheme for cloud storage is a mechanism that checks the integrity of outsourced data. Cloud storage deduplication is a technique that helps cloud service providers save on storage costs by storing only one copy of a file when multiple users outsource the same file to cloud servers. However, combining storage auditing and deduplication techniques can be challenging. To address this challenge, in 2019 Hou et al. proposed a cloud storage auditing scheme with deduplication that supports different security levels of data popularity. This proposal is interesting and has practical applications. However, in this paper, we show that their proposal has a flaw: the cloud or other adversaries can easily forge the data block's authenticators, which means the cloud can delete all the outsourced encrypted data blocks but still provide correct storage proof for the third-party auditor. Based on Hou et al.'s scheme, we propose an improved cloud storage auditing scheme with deduplication and analyze its security. The results show that the proposed scheme is more secure.
A signal quality assessment method for fetal QRS complexes detection
Authors: Zhong Wei , Mao Li , Du Wei
Published: February 2023

Objective

Non-invasive fetal ECG (NI-FECG) provides a non-invasive method to monitor the health of the fetus. However, the NI-FECG is easily interfered by noise, which makes the signal quality decline, leading to the fetal heart rate (FHR) monitoring becoming a challenging task.

Methods

In this work, an algorithm for dynamic evaluation of signal quality is proposed to improve the multi-channel FHR monitoring. The innovation of the method is to assess the signal quality in the process of multi-channel fetal QRS (FQRS) complexes detection. Specifically, the detected FQRS is used as quality unit. Each quality unit can be a true R peak (TR) or a false R peak (FR). It is the basic quality information in this work. The signal quality of each channel is estimated by estimating the correctness of the detection results. Further, the TRs of all channels can be fused to obtain more reliable fetal heart rate monitoring.

Main results

Analysis results demonstrate that the proposed algorithm is capable of selecting the good quality signal for FQRS detection achieving 97.40% $ PPV $, 98.33% $ SE $ and 97.86% $ F_1 $.

Significance

This work sheds light on the quality assessment of fetal monitoring signal.
