The Fakes of Sexual Narrative in the Information Warfare
Authors: Demchuk Ruslana
Published: October 2022

The proposed article is based on the report presented at the conference “The Days of Science at NaUKMA” on January 26, 2022, just one month before the Russian invasion. Back then it seemed impossible. The active phase of the previous military confrontation ended in 2015 and it transformed into a positional and hybrid warfare. Since then, some representatives of Ukrainian scientific community, under the guise of “science without politics,” continued to cooperate with Russia, from publishing their research in Russian journals to holding joint conferences and more. The author of the article, despite the rejection, did not see this as an intention but rather a misunderstanding of the objective reality. Therefore, the purpose of the report was to prove that hybrid warfare is a covert but real war in the context of post-truth.Post-truth as a mode of meanings functioning is a shift of boundaries between the real and the imaginary; it does not equal lie but rather is negligence, indifference to the truth, which entails uncertainty of positions and substitutions of concepts. Fake, on the other hand, is a specific form of misinformation which has accompanied hybrid warfare. However, on February 24, 2022, the war took the form of an open escalation, the planning of which was denied by Russia in accordance with the genre of hybrid warfare with its cortege of fakes.The choice of the topic focused on the sexual narrative is relevant, in particular due to the public joke of Russian President Putin towards Ukrainian President Zelensky at a press conference in Moscow on February 8, 2022, directly related to rape, which became widely known in the media. As it turned out later, it was not a joke but a certain affirmation, an intention of thinking, which turned into mass rapes of Ukrainian women and children by Russian soldiers in the new stage of Russia’s war against Ukraine.

Formation of information and communicative competence of students in educator-supervisor’s work
Authors: Rukosueva Tatiana V. , Reshetneva Irina T.
Published: October 2022

Abstract. We consider the role of a supervisor in a higher educational institution. The delay in the maturation of young people observed in recent decades makes this work relevant especially in the first years of higher education. The work of the supervisor in the student group on the formation of information and communication competence should include the study of the emotional and cognitive sphere of students, the peculiarities of their interpersonal relationships and monitoring of the psychological state of the collective and individual. An important part of the supervisor's work is the choice of approaches to the formation of a student team, which often unites representatives of different nationalities and different cultural traditions. The key direction is the diagnosis of the psychological atmosphere in the student team. Examples of diagnostic tests that are simple and accessible for use in the practice of an educator-supervisor are given. The methods that can be used in the supervisor’s educational work are analyzed. Special attention is paid to the need for close cooperation with specialists of specialized departments of pedagogy and psychology, providing substantial professional advice in solving these problems. The work of the educator-supervisor, aimed at the formation of information and communication competence of students, contributes to the process of adaptation to new living conditions, which ultimately leads to an improvement in the quality of education and further successful implementation in professional activities.
Az Európai Unió által számított kérdőíves felmérésen alapuló üzleti hangulatindexek és vállalati pénzügyi teljesítmény: egy kísérleti kutatás eredményei
Authors: Nyitrai Tamás
Published: October 2022

A tanulmány az Európai Unió által havi gyakorisággal számított üzleti hangulatindexek idősoros értékeit vizsgálja, abból a szempontból, hogy mutatkozik-e számottevő kapcsolat a Magyarországon működő vállalatok átlagos pénzügyi teljesítménye és a konjunktúraindexek közt. Az empirikus vizsgálathoz felhasznált minta vállalatai esetén a 2013–2020 közötti időszakra vonatkozóan az a következtetés vonható le, hogy az átlagos pénzügyi helyzet és az unió által számított üzleti hangulatindexek éves átlaga hasonlóan alakult. A kapcsolat erősségét azonban a Covid19-járvány hazai megjelenése számottevően csökkentette a kis-, a közép- és a nagyvállalatok esetében.

La violencia contra las mujeres ha sido una problemática social que ha atravesado de forma sistémica dentro y fuera de México, incluso en el espacio de Internet que, al tratarse de un entorno inmenso de tráfico de información, se vuelve en un espacio crítico y propicio para el traslado de las violencias cara a cara, a las digitales. Los objetivos de la investigación fueron analizar la prevalencia de las diferentes formas de violencia digital en mujeres mexicanas, analizar las emociones experimentadas durante el episodio, conocer el porcentaje de mujeres que denunciaron y ante qué instancia se realizó. Se aplicó un instrumento elaboradoad hoc a 168 mujeres mexicanas, con una media de edad de 26.11 años (D.T.= 7.09). El 82.7% ha experimentado insultos a través de internet, los principales agresores para los diferentes tipos de violencia fueron la pareja y/o expareja. La impotencia y la ansiedad fueron las emociones más identificadas. El 82.1% no denunció el hecho. La violencia digital es la suma de las otras violencias y permisos patriarcales, con coste en la vida de las mujeres mexicanas. Su visibilización así como sensibilización y concienciación en la sociedad, al reconocer que lo virtual es real, promueve la escucha activa y respeto a las experiencias, abonando a priorizar en la salud mental y la cultura de la denuncia.

Personajes “euphoricos”: lo Crip y lo Queer a través de la intertextualidad audiovisual en Euphoria
Authors: Esteban Bretones Damian
Published: October 2022

Géneros, sexualidades y cuerpos no normativos, aparecen representadas en series de televisión. A este respecto, las teorías crip y queer exponen, de forma crítica, la capacidad corporal obligatoria frente a la discapacidad, y la obligatoriedad heteronormativa frente a multitudes de géneros y sexualidades. 

Este artículo pretende emplear la perspectiva crip/queer para analizar a tres de los personajes principales en la primera temporada de la serie Euphoria (HBO, 2019), a través de las referencias intertextuales audiovisuales. Y reflexionar si se sigue privilegiando la heteronormatividad patriarcal sin discapacidad o, por el contrario, hay una modificación del discurso para cuestionar la perspectiva dominante. Esta transformación discursiva se produce con la identificación con personajes queer/crip, y mediante un juego intertextual performativo que reinterpreta esas referencias. Ambos aspectos producen un desplazamiento, en unos casos, y una disolución, en otros, del dispositivo activo/pasivo -o sujeto/objeto- para expresar el deseo y las relaciones entre personajes.
La música de John Williams en Cuentos Asombrosos. Un análisis de la secuencia de apertura
Authors: Valverde Amador Andrés
Published: October 2022

Este artículo analiza la secuencia de apertura de la serie Cuentos Asombrosos (NBC, 1985-1987) desde un enfoque narrativo y musical. De este modo, se busca poner en valor la contribución del compositor John Williams a la televisión norteamericana en la década de los 80. Asimismo, se analizan diversos estilemas presentes en la pieza, señalando así elementos comunes en la escritura sinfónica del compositor. En primer lugar, se contextualiza la figura de Williams y la música televisiva, para más tarde centrarnos en el año 1985 con motivo del lanzamiento de la serie. Tras esto se realiza el análisis de la secuencia de apertura en dos secciones: la primera en los aspectos visuales y narrativos; y la segunda centrada exclusivamente en las características sinfónicas y estilo de escritura. Todo ello persigue destacar la figura de Williams en torno a la creación de elaboradas miniaturas orquestales vinculadas al microrrelato televisivo. Y cuya fidelidad a su tipo de escritura —ya sea en el cine o la sala de conciertos— se adapta al medio televisivo para conferirle valor musical a dicho microrrelato.

Published: October 2022

One of the challenges related to reservoir engineering studies is working with essential high-dimensional inputs, such as porosity and permeability, which govern fluid flow in porous media. Dimensionality reduction (DR) methods have enabled spatial variability in constructing a fast objective function estimator (FOFE). This study presents a methodology to select an adequate DR method to deal with high-dimensional spatial attributes with more than 105 dimensions. We investigated 18 methods of DR commonly applied in the literature. The proposed workflow accomplished (1) definition of the adequate number of dimensions; (2) evaluation of the time spent for each data set generated using the elapsed computational time; (3) training using the automated machine learning (AutoML) technique; (4) validation using the root mean square logarithmic error (RMSLE) and the confidence interval (CI) of 95%; (5) a score equation using elapsed computational time and RMSLE; and (6) consistency check to evaluate if the FOFE is reliable to mimic simulator output. We used FOFE to generate risk curves at the final forecast period (10,957 days) as an application. We obtained methods that reduced the high-dimensional spatial attributes with a computational time lower than 10 minutes, enabling us to consider them in the FOFE building. We could deal with high-dimensional spatial variability from those selected approaches. Moreover, we can use the DR method selected to deal with high complexity problems to build an FOFE and avoid overfitting when a massive number of data are used.

Published: October 2022

Background
The breastfeeding rate in China is lower than that in many other countries and the extent of adoption of the “Feeding Recommendations for Preterm Infants and Low Birth Weight Infants” guideline in NICUs remains unclear.
Method
A web-based survey about the current status of human milk feeding and enteral feeding practices at NICUs was sent to all China Neonatal Network’s cooperation units on September 7, 2021, and the respondents were given a month to send their responses.
Results
All sixty NICUs responded to the survey,the reply rate was 100%. All units encouraged breastfeeding and provided regular breastfeeding education. Thirty-six units (60.0%) had a dedicated breastfeeding/pumping room, 55 (91.7%) provided kangaroo care, 20 (33.3%) had family rooms, and 33 (55.0%) routinely provided family integrated care. Twenty hospitals (33.3%) had their own human milk banks, and only 13 (21.7%) used donor human milk. Eight units (13.3%) did not have written standard nutrition management guidelines for infants with body weight < 1500 g. Most units initiated minimal enteral nutrition with fresh mother’s milk for infants with birth weight ˂1500 g within 24 h after birth. Fifty NICUs (83.3%) increased the volume of enteral feeding at 10–20 ml/kg daily. Thirty-one NICUs (51.7%) assessed gastric residual content before every feeding session. Forty-one NICUs (68.3%) did not change the course of enteral nutrition management during drug treatment for patent ductus arteriosus, and 29 NICUs (48.3%) instated NPO for 1 or 2 feeds during blood transfusion.
Conclusion
There were marked variations, but also similarities, in human milk feeding and enteral feeding strategies between NICUs. Establishing national-level feeding guidelines for preterm and low birth weight infants and quality improvement of cooperation at the national level were needed.

Bambara groundnut ( Vigna subterranea (L.) Verdc) are a neglected and underutilized crop species that is in high demand among Sub-Saharan African smallholder farmers. Despite the high demand, there are no improved varieties available to smallholder farmers in Malawi. This study aimed at characterizing agro-morphological traits and identifying genetic diversity using Diversity Array Technologies Sequence Low Density (DArTseqLD) Single Nucleotide Polymorphism (SNP) markers in order to identify unique traits that can be used in germplasm discrimination for seed production and genomic variation for crop improvement. Forty germplasm were evaluated at the Crops and Soil Sciences Department's farm of Lilongwe University of Agriculture and Natural Resources, Bunda College. From forty germplasm, 188 samples were selected for genotyping using DArTseqLD SNP markers. Data on agro-morphological traits were collected following Bambara groundnut descriptor and subjected to multivariate analysis. Principal Component Analysis revealed a total variation of 53%. The study generated 1048 DArTseqLD SNP markers. Analysis of molecular variance (AMOVA) revealed 84% and 13% variation among and within the Bambara groundnut germplasms respectively, 3% variations was observed among the populations. Cluster analysis based on genotypic data grouped the 188 samples into 9 clusters. Based on phenotypic and genotypic data, it can be concluded that there is a significant degree of variation and genetic diversity in the germplasm evaluated that can be used by farmers in seed production and plant breeders in crop improvement program.

Published: October 2022

Background:
Bcl-6 is an essential factor control Tfh cells differentiation. T lymphocytes assistance B lymphocytes regulate IgE secretion is a crucial part of asthma. However, Bcl-6 direct effect on asthmatic characteristics, such as IgE secretion is unknown.
Methods:
We adopted OVA-induced BALB/c mice, and Bcl-6 small interfering RNA to inhibit Bcl-6 expression. There were five groups: Control, Blank carrier, Asthma, Bcl-6 siRNA interference, and DXM-treated. Then mice were euthanized, collected lungs tissues, peripheral blood, lymph nodes and spleen. Histopathological diagnosis, AR and LC of each group were detected. Expression levels of surface molecular markers on Tfh cells in pre-mentioned tissues were examined by FCM. Bcl-6 mRNA expression was detected by RT-PCR, and Bcl-6 protein grayscale was detected by Western-blot. Finally, the concentration of IgE and IgG1 in peripheral blood and BALF were detected, and correlation analysis with the Tfh cells ratio in counterparts was applied.
Results:
Typical pathological changes were observed in lung tissue of asthmatic mice, that was alleviated by Bcl-6 antagonism and DXM. Asthmatic ones had increased AR and decreased LC, while Bcl-6 siRNA interference or DXM treatment could reduce AR and improve LC. FCM indicated that Tfh cells ratio in peripheral blood, lymph nodes, and spleen of asthmatic mice increased significantly comparing to control ones, and that also decreased significantly after Bcl-6 siRNA interferencing and DXM treatment. The trend occured in eosinophils ratio of BALF. Applying RT-PCR accessed the Bcl-6 mRNA expression in PBMCs, which was significantly higher of asthmatic mice than control ones. Whereas that was significantly decreased when Bcl-6 inhibited and DXM treated. Bcl-6 protein expression was similar to that of mRNA expression in Western-blot. As well as the IgE secretion in serum and BALF, B cells expression in PBMCs have the same trend. Besides, in asthmatic mice, the Tfh cells ratio in peripheral blood was strong positively correlated with the level of IgE in serum and BALF, but not that of IgG1.
Conclusions:
Inhibition of Bcl-6 expression can ameliorate airway inflammation and airway hyper-responsiveness in asthmatic mice by blocking Tfh cell differentiation, which concomitantly reduces B cells regulation IgE production.

Authors: Liu Caixia , Kou Lijun , Ma Xun , Wang Jing , Liu Yangyang , Gao Shengjie , Kong Cuilian , Shi Weidi , Lv Shuangfei , Ren Huijie , Zeng Dongdong
Published: October 2022

Background
Listeria monocytogenes is a facultative anaerobic zoonotic intracellular pathogen. Pathogenicity island 4 (LIPI-4) is a newly discovered virulence gene cluster involved in the central nervous system (CNS) infection of L. monocytogenes. To explore the role of LIPI-4 in the virulence of L. monocytogenes, a frozen chicken isolate LM928 LIPI-4 gene deletion strain (ΔLIPI-4) and complement strain (CΔLIPI-4) were constructed to infect human brain microvascular endothelial cells (HCMECs). The effect of LIPI-4 on L. monocytogenes virulence was determined through bacterial adhesion, cellular invasion, and intracellular proliferation evaluation by noting the median lethal dose (LD50) in mice, the number of bacteria in the tissue, and the expression of virulence factors in vivo and in vitro by RT-qPCR.
Results
The results showed that LIPI-4 deletion decreased cellular adhesion, cellular invasion, and intracellular proliferation of L. monocytogenes to HCMECs cells. The LD50 of ΔLIPI-4 infected mice was 1.0 and 0.7 orders of magnitude lower than that of LM928 and CΔLIPI-4, respectively. The tissue load of ΔLIPI-4 was significantly higher (P < 0.05) than that of LM928 and CΔLIPI-4. In BHI culture, the expression of important virulence genes was significantly down-regulated (P < 0.01) in the ΔLIPI-4 strains. However, transcription levels of actA, inlA, inlB, and inlC were significantly up-regulated (P < 0.01) while hly, prfA, plcA, and plcB were significantly down-regulated (P < 0.01) in ΔLIPI-4 infected HCMECs.
Conclusion
This data suggests that LIPI-4 acts as a virulence factor involved in L. monocytogenes infection. Its deletion may contribute to decreasing the virulence of L. monocytogenes in mice.
Elevated of HSP90 associates with expression of EGFR levels and predicts poor prognosis in non-small cell lung cancer patients
Authors: Zhou Ying , Tang Yaoxiang , Luo Jiadi , Yang Yang , Zang Hongjing , Ning Yue , Zheng Hongmei , Fan Songqing , Wen Qiuyuan
Published: October 2022

Background
The molecular chaperone protein HSP90 is a crucial mediator of proteostasis in eukaryotic cells under various stress conditions. EGFR participates in signal transduction relating to tumorigenesis and progression. The relationship between the combined expression of HSP90 and EGFR in non-small cell lung cancer (NSCLC) and clinicopathological features and long-term prognosis is not clear.
Methods
We analyzed The Cancer Genome Atlas (TCGA) gene data from Xiantao platform and GEPIA2 to study the expression of HSP90 and EGFR on mRNA level and their correlation in patients with NSCLC. Besides, 53 normal lung samples and 352 paraffin-embedded NSCLC were selected randomly for immunohistochemical (IHC) staining with anti-HSP90 and anti-EGFR antibodies, respectively.
Results
The TCGA data revealed that HSP90 and EGFR expression on mRNA and protein was significantly higher in NSCLC patients than non-cancerous lung tissues (Non-CLT) (both p < 0.05). Moreover, increased HSP90 showed a positively correlation with EGFR in mRNA levels (both p < 0.0001). Higher HSP90 expression appeared in lymph node metastasis (LNM) or advanced clinical stage of NSCLC (p = 0.019, p = 0.013, respectively). The survival rate of high expression of HSP90 and EGFR alone or in combination was lower than that of other phenotypes in NSCLC (p < 0.001, P = 0.011, p < 0.001, respectively). In multivariate Cox proportional hazard regression analysis, HSP90 and EGFR were further identified as independent poor prognostic factors in NSCLC.
Conclusions
Elevated HSP90 and EGFR might suggest a synergistical role in promoting the development in patients with NSCLC. High expression of these two proteins might be novel prognostic biomarker for NSCLC, who provides potential application value for NSCLC targeted therapy.
Population Divergence in the Mate Choice of Tribolium castaneum and Its Association with Gut Bacteria
Authors: Wang Zhengyan , Wang Yang , Lu Yujie
Published: October 2022

To reveal population divergence in the mate choice and its mechanistic basis, the mating rhythm, mating preference and male volatile profiles of Tribolium castaneum were studied. During ten days after emergence, six geographical populations of T. castaneum exhibited an identical daily or diurnal mating rhythm. Males showed significant attraction to females while females did not show attraction to males. Furthermore, male attraction to females varied significantly within six populations, while female preference to males did not. Males from the HBWH population were most attractive to females sequentially followed by males from the populations of SHJD, HNZZ, GA1, GDST, and ZJJX, which was positively correlated with their 4,8-dimethyldecanal (DMD) production. Gnotobiotic reinoculation of two gut bacteria, Citrobacter freundii and Escherichia coli, to axenic males significantly enhanced their attraction to females and DMD production. It could be concluded that: (i) in the mate choice of T. castaneum, males were more like the sexual pheromone senders and females were the pheromone receivers; (ii) there was detectable divergence in the chemical communication among six populations of T. castaneum, which could be attributed to alterations in the male pheromone production rather than changes in the female pheromone perception; and (iii) gut bacteria could modulate the chemical communication of the host by interfering with the pheromone production. Such knowledge will provide insights into optimizing trapping technologies for pest management.

Published: October 2022

For long-term land management, understanding the scope, direction, and agents of LULC change, as well as their configuration across geographical and temporal dimensions, is essential. This study looked at the patterns and extents of LULC change in Chifra District's Shekayboru Area for that aim. Landsat imagery from TM and ETM+ (2009/10) and OLI were used to investigate the dynamics of LULCC (2015 and 2020). A hybrid method was used to categorize the LULC maps for each period using the results of supervised classification and intense on-screen-digitizing approaches. Three major LULC types (vegetation, cultivation, and bare lands) were identified, with overall accuracies ranging from 91.3 to 100%. According to the 2009/10 LULC classification map, bare lands had the highest area coverage (around 87%), while in 2015 and 2020, both vegetation and cultivated lands showed increment trends of 26 and 28 percent (2015), and 29 and 44 percent (2020), respectively, and bare lands showed decrement trends of 46 and 28 percent, respectively. The study area's Focus Group Discussions and interviews further revealed that, as a result of the water spreading weir, vegetation and cultivated fields have increased over time, and local villagers have taken up maize farming. Better soil and water conservation methods may be responsible for the increase in plant cover. The outcomes of this study will help design future soil and water conservation measures in response to sustainable land management. According to the researcher, a study of soil fertility, quality, and moisture content should be conducted in the future.
Scaling up an intervention to protect preterm infants from neurodevelopmental disabilities – findings from a qualitative process evaluation comparing standard with enhanced Quality Improvement support packages for maternity units in England
Authors: Redwood Sabi , Pithara-McKeown Christalla , Stone Tracey , Treloar Emma , Donovan Jenny L , Luyt Karen
Published: October 2022

Background
A Quality Improvement strategy (PReCePT) was used in a standard and intensive format to scale up a clinical intervention (administering magnesium sulphate to women in preterm labour) across all maternity units in England to protect prematurely born infants from neurodevelopmental disabilities. Formal evaluations reported the effectiveness of the standard package alone in increasing the administration of magnesium sulphate. In this paper, we focus on the findings of the process evaluations, using Normalisation Process Theory to explain how different implementation contexts generated the observed outcomes relating to normative and relational restructuring, and sustainment.
Methods
Interviews were conducted with key individuals in implementation leadership positions nationally and locally. Interviews were analysed initially using the framework method. We then engaged recursively with NPT constructs to generate generalisable insights with pragmatic applicability in other scenarios.
Results
In total, 72 interviews were conducted with good representation from units across England, and staff from the national Academic Health Science Network. We found that all units irrespective of whether they received a standard or enhanced QI package were successful in the ‘normative restructuring’ of their setting to enable magnesium sulphate to be administered. This suggests that this implementation outcome is necessary to achieve improvements. However, it may not be sufficient to sustain and normalise the changes once additional resources have been withdrawn. Sustainment, our findings suggest, required ‘relational restructuring’ to accommodate altered workflows and facilitate the sharing of responsibilities and tasks in daily practice. Relational restructuring was more likely to have been achieved units receiving enhanced QI support but also happened in units with standard QI support, especially in those where perinatal teamworking was already well established.
Conclusion
Unlike other large QI focused spread-and-scale programmes which failed to show any impact on outcomes, the PReCePT programme in both the enhanced and standard support packages led to improvements in the uptake of magnesium sulphate. The findings suggest that QI programmes interact with the enabling factors, such as strong interprofessional team working, already present in the setting. A standard package with minimal support was therefore sufficient in settings with enabling factors, but enhanced support was required in units where these were absent.
Changes in the South American Monsoon System since the Last Glacial Maximum
Authors: Custódio Igor Stivanelli , Dias Pedro Leite da Silva , Wainer Ilana , Prado Luciana F.
Published: October 2022

The main objective of this study is to investigate the spatial-temporal variability and the climate forcing influence during the last 21,000 years of the South American Monsoon System (SAMS). TraCE-21k simulations Full and Single Forcings experiments were used. The identification of spatial variability patterns associated to the core of monsoon region and the South Atlantic Convergence Zone (SACZ) patterns are based on multivariate EOF analysis (precipitation, humidity, zonal and meridional wind) which produces two main modes: the South American Large Scale Monsoon Index (LISAM) and the SACZ mode. The LISAM and SACZ modes show that the TraCE-21k represents the SAMS and SACZ patterns and the comparison to the 20th Century reanalysis EOF analysis show significant agreement. LISAM time series proved to be an important instrument to identify monsoon precipitation variability, consistent with the regime changes registered in climatic proxies. The freshwater pulses forcing in TraCE-21k is a determining factor for the observed changes in the precipitation regime, mainly for the periods between the Heinrich Stadial 1 and the Younger Dryas. The results show that the observed and modeled SACZ southward shift in the Late Holocene is mainly modulated by insolation changes, with stronger correlation observed since the Mid-Holocene period. Through wavelet analysis, it was noted that energy was transferred from low frequencies to high frequencies during Bolling Allerod for the full forcing and freshwater pulse experiments in the Northern Hemisphere, with the SAMS multidecadal variability increasing from the early Holocene with direct influences of orbital forcing and ice cover.

Authors: Yang Qiang , Chung Yongmann
Published: October 2022

Travelling waves induced by spanwise Lorentz force for skin-friction drag reduction are studied in the present work using direct numerical simulations, with particular focus on the streamwise and spanwise travelling waves. The overall picture of drag reduction in the ω+ − κx+ − κz+ parameter space is uncovered. It is found that both drag reduction maps for the streamwise and spanwise travelling waves are featured with a drag reduction (DR) region and a drag increase (DI) region. For the streamwise travelling wave of spanwise Lorentz force, the DR and DI regions are located in the same parameter regime compared to that of the streamwise travelling wave of spanwise wall velocity, while for the spanwise travelling wave, the DR variation at any fixed κz+ is similar to the spanwise oscillating Lorentz force. An exploration of the oblique travelling wave with an angle to the mean flow shows that the optimal drag reduction appears when the wave travels backward relative to the flow direction, and the “ribbon” structure is a general phenomenon appearing in all oblique travelling wave cases. The ensemble averaged positive and negative quasi-streamwise vortices become asymmetric when the travelling wave is imposed, and the near-wall high- and low-speed streaks are significantly twisted in the spanwise direction. Spanwise oscillation, streamwise and spanwise travelling waves share strong similarity in the statistics, energy spectra as well as turbulent structure modulation.

In primates, neurons giving rise to the corticospinal tract (CST) are distributed in several motor-related areas of the frontal lobe, such as the primary motor cortex (M1), the supplementary motor area (SMA), and the dorsal and ventral divisions of the premotor cortex (PMd, PMv). Recently, we have analyzed the morphology of basal dendrites of CST neurons, i.e., large layer V pyramidal neurons in macaque monkeys and shown that the complexity and spine density of the dendrites vary across the motor-related areas. Here, we investigated the alterations in basal dendrite morphology of CST neurons after spinal cord injury (SCI). In our SCI model, both the intersection number and the spine density of basal dendrites were highly decreased throughout the motor-related areas. Notably, these events were less prominent for the PMd than for the M1, SMA, and PMv. When we further compared the density changes post-SCI of the filopodia-, thin-, stubby-, and mushroom-type spines in individual areas, it was found that the density of filopodia-type (immature) spines was increased for all the areas, whereas the other types of spines exhibited their density reductions. Again, such spine density reductions were so limited for the PMd as compared to the M1, SMA, and PMv.

This study examined the role of dispositional mindfulness in the association between intelligence and prosocial behavior (PB). A total of 759 college students (mean age is 22.03; 477 females) participated in exchange for extra credit in psychology course. The results confirmed a positive relationship between intelligence and PB as revealed by many studies, with empathy playing a mediating role. Mindfulness negatively moderated all the hypothesized pathways between research variables. Specifically, with the increase of the levels of dispositional mindfulness (1) the intelligence-PB association changed from positive to negative, (2) the intelligence-empathy association changed from positively significant to insignificant, (3) the empathy-PB association changed from stronger to weaker. These findings may suggest some limitations of mindfulness. That is, present moment awareness and acceptance of the status quo may result in reduced arousal when witnessing others suffering thereby preventing high intelligence people from helping the sufferers get rid of trouble.
The HUJI Corpus of Spoken Hebrew: An interaction-oriented design of a corpus
Authors: Marmorstein Michal , Matalon Nadav
Published: October 2022

The paper reports on the creation of the HUJI Corpus of Spoken Hebrew (HUJICorpus) which documents naturally occurring speech and interaction in Modern Hebrew. Data come from telephone conversations recorded during the years 2020–2021. The focus on telephone conversations as a primary resource enables to reduce some of the semiotic complexity and concentrate on the linguistic (verbal and vocal) features of the interaction. Drawing on the principles of Interactional Linguistics, the recordings are transcribed using a highly granular system of formal annotation which accurately captures the temporal, sequential and prosodic aspects of talk-in-interaction. The audio files and transcripts were made freely accessible online, thus filling a widely acknowledged need for a publicly accessible and updated corpus of spoken Modern Hebrew.

Longitudinal serum samples, nasopharyngeal/nasal swabs and rectal swab samples were collected from eighty-nine individuals (median age 66 y) with SARS-CoV-2 PCR-positive test results at Linköping University Hospital. Samples were collected from the initial visit and thereafter for up to 2 years of follow-up. The presence of serum IgG and IgA against SARS-CoV-2 antigens (S1-spike, nucleocapsid, and NSP3) was analysed. Nasal and rectal swabs were tested for the presence of mucosal IgA against the outer envelope S1 spike and the nucleocapsid protein. Ninety percent of the participants were seropositive for SARS-CoV-2 recombinant proteins on Day 28 after study entry, and all (100%) were seropositive based on samples collected 2 months or later. Almost all (95%) developed serum SARS-CoV-2-neutralizing antibodies that were measurable from 6 to 24 months. The most common antibody responses (both serum IgG, mainly IgG1, and in nasal mucosa IgA) reacted with the S1-spike protein and the nucleoprotein. In samples collected from nasal tissues, IgA anti-S1 spike protein was mainly observed during 2 months of follow-up. In a subpopulation (18% of tested individuals), rectal IgA swabs showed the presence of anti-S1 spike IgA for 1 month of follow-up among the participants studied. .
Modification of TiO 2 nanotubes by graphene - strontium and cobalt molybdate perovskite for efficient hydrogen evolution reaction in acidic medium

Published: October 2022

Herein, we demonstrate that modification of TiO2 nanotubes with graphene-strontium and cobalt molybdate perovskite can turn them into active electrocatalysts for hydrogen evolution reaction (HER). For this purpose, a simple method of hydrothermal synthesis of perovskites was developed directly on the TiO2 nanotubes substrate. Moreover, the obtained hybrids were also decorated with graphene oxide (GO) during one-step hydrothermal synthesis. The obtained materials were characterized by scanning electron microscopy with energy dispersive X-ray analysis, Raman spectroscopy, and X-ray diffraction analysis. Catalytic properties were verified by electrochemical methods (linear voltammetry, chronopotentiometry). The obtained hybrids were characterized by much better catalytic properties towards hydrogen evolution reaction compared to TiO2 and slightly worse than platinum. The optimized hybrid catalyst (decorated by GO) can drive a cathodic current density of 10 mA cm−2 at an overpotential of 121 mV for HER with a small Tafel slope of 90 mV dec−1 in 0.2 M H2SO4.
Love-type waves in multilayered elastic media containing voids: Haskell matrix method
Authors: Kaur Savkirat , Khurana Aarti , Tomar S. K.
Published: October 2022

Propagation of Love-type waves is investigated in a model of multilayered elastic solid half-space containing voids. Using Haskell matrix method, the dispersion relations are derived for two situations of topmost boundary surface of the model: (a) when it is stress-free and (b) when it is rigid. For both the situations, there exist two wave fronts of Love-type waves that are dispersive in nature and propagating with distinct speeds. One of these wave fronts is analogous to that propagating through multilayered elastic half-space without voids, while the other front is new and appeared due to the presence of voids in the model. Conditions of propagation of both the wave fronts of Love-type waves are derived analytically for 2-layered model. Comparison of dispersion curves corresponding to both these fronts is also depicted graphically for 2-and 3-layered models with stress-free boundary surface. Effect of the thickness of layer and the presence of void parameters on the corresponding wave speeds is studied and depicted graphically for a specific 2-layered model.
Finite differences and quadratures: General formulae from deferred correction method
Authors: Koyaguerebo-Imé Saint-Cyr Elvi Rodrigue
Published: October 2022

In this paper deferred correction method is applied to derive explicitly different arbitrary high order finite difference (FD) formulae for the numerical differentiation of analytic functions. With this approach, various first and second order FD formulae are given with error terms explicitly expanded as Taylor series of the analytic function. These lower order approximations are successively improved by one or two to give FD formulae of arbitrary high order. The new approach efficiently recovers all the existing FD formulae on uniformly spaced grid points and the standard backward, forward and central FD formulae which are usually only given heuristically in terms of formal power series of FD operators. Examples of new FD formulae suited for timestepping schemes are built, and a stable self-starting time-stepping scheme of order four is provided to illustrate the application of the new FD approach to time-stepping method. The new approach extends to unequally spaced grid points and allows to Gaussian quadratures with exact error terms while it can also be used to correct high order Newton-Côte quadratures to quadratures with weights all positive. Contrary to existing quadrature rules, the new approach allows to a better approximation of the integral of a function f on an interval [a,b] using arbitrary given interpolation nodes within this interval.

PURPOSE
Does preimplantation genetic testing for aneuploidy (PGT-A) in embryos help women of advanced maternal age (AMA) achieve better reproductive outcomes?
METHODS
Multicenter, controlled retrospective study, a total of 267 patients (n = 267) were recruited, of which 53 patients (PGT-A group) consented to PGT-A, followed by euploid embryo transfer, whereas the remaining 214 patients (non-PGT-A group) underwent embryo transfer of un-screened morphologically graded blastocysts.
RESULTS
A significant increase in the clinical pregnancy rate was observed in the PGT-A group when compared to the non-PGT-A group (71.6% vs. 51%, p = 0.007), while the miscarriage rate was found to be lower in the PGT-A group compared to the non-PGT-A group (11% vs. 25%, p = 0.02). The live birth rates observed in either group were statistically nonsignificant (62.2% vs 51%, p = 0.14). In the PGT-A group, similarly, the implantation rate was found to be significantly higher than in the non-PGT-A group (53% vs. 33%, p = 0.007).
CONCLUSION:
The data suggest that PGT-A testing in women of advanced maternal age can improve their reproductive outcomes.
