Published: December 2021

Attention deficit hyperactivity disorder (ADHD) is a prevalent neurodevelopmental condition characterized by diminished attentional control. Critically, these difficulties are related to negative consequences in real-life functioning both during development and into adulthood. There is now growing evidence that modulating the underlying neural circuits related to attention can improve behavior and brain function in children with ADHD. We have previously shown that game-based digital therapeutics targeting a key neural marker of attention–midline frontal theta (MFT)–yield positive effects on attentional control in several populations. However, the effects of such digital therapeutics in children with ADHD and no other comorbidities has not been yet examined. To address this gap, we assessed a sample of 25 children with ADHD (8–12 years old) on neural, behavioral, and clinical metrics of attention before and after a 4-week at-home intervention on an iPad targeting MFT circuitry. We found that children showed enhancements on a neural measure of attention (MFT power), as well as on objective behavioral measures of attention and parent reports of clinical ADHD symptoms. Importantly, we observed relationships between the neural and behavioral cognitive improvements, demonstrating that those children who showed the largest intervention-related neural gains were also those that improved the most on the behavioral tasks indexing attention. These findings provide support for using targeted, digital therapeutics to enhance multiple features of attentional control in children with ADHD.

Published: January 2022

The aim of the work was study of the variability of fruit chemical composition of O. palustris (2 samples) and O. macrocarpus (6 samples) cultivars and forms introduced in CSBG depending on the conditions of the year. Biochemical research of the content of dry substance, ascorbic acid, sugars, titratable acidity, anthocyanins, pectins, protopectins and catechins in berries of these samples were conducted. The chemical composition was analyzed by conventional methods.
O. palustris surpasses O. macrocarpus in the content of ascorbic acid and titratable acidity, but is inferior to it in the accumulation of anthocyanins, pectins and protopectins. In comparison with the studied samples of both species, the native O. palustris accumulates the greatest amount of ascorbic acid and the least amount of sugars. The early cultivars of O. macrocarpus exceeds the mid-season cultivars and are close to late-maturing ones in terms of ascorbic acid content. The difference in the accumulation of other ingredients in the fruits of both O. palustris and O. macrocarpus is not statistically significant. According to the chemical composition of berries, O. palustris and O. macrocarpus are promising for introduction in the South of Western Siberia.

Published: December 2021

Global Navigational Satellite System (GNSS) over the past and present time has shown a great potential in the retrieval of the distribution of water vapour in the atmosphere. Taking the advantage of the effect of the atmosphere on GNSS signal as they travel from the constellation of satellite to ground-based GNSS receivers such that information (water vapour content) about the atmosphere (mostly from the troposphere) can be derived is referred to as GNSS meteorology. This paper presents the spatiotemporal variability of Precipitable Water Vapour (PWV) retrieved from ground–based Global Navigation Satellite System (GNSS) stations over Nigeria for the years 2012 to 2013. In this paper, the GNSS data were processed using GAMIT (ver. 10.70). The GNSS PWV were grouped into daily and monthly averages; the variability of the daily and monthly GNSS PWV were compared and validated with the daily and monthly PWV from National Centre for Environmental Prediction (NCEP) and monthly Rainfall data for the study years respectively. The results revealed that the spatiotemporal variability of PWV across Nigeria is a function of geographic location and seasons. The result shows that there is temporal correlation between GNSS PWV, NCEP PWV and rainfall events. The research also affirms that GNSS PWV could be used to improve weather forecasting/monitoring as well as climate monitoring.
A tridimensional view of the Hispanic Health Paradox: Its relationship with faith, the enclave theory, and familism
Authors: Hem-Lee-Forsyth Shivaughn , Sandoval Bibiana , Bryant Hanna 
Published: December 2021

This paper examines the "Hispanic (American) Health Paradox," the juxtaposition of Hispanics’ longer lifespan than the average American amid numerous inequities regarding social determinants of health. Hispanic Americans endure multiple health disparities with a higher incidence and prevalence of chronic conditions. They also experience multiple psychosocial and physical health challenges, including higher rates of food insecurity, poverty, segregation, discrimination, and limited or no access to medical care. Nevertheless, Hispanics enjoy better physical well-being and lower mortality rates when compared to non-Hispanics in the United States (Ruiz et al., 2021). This project aims to analyze the sources of this group’s biosocial advantages and resilience, allowing them to have a longer lifespan amidst their lower health status and increased risk for chronic conditions. It explores the political and social justice implications of these inequities. It also examines the strategies to close the gap on Latinos' current health care disparities via public policy aspects of federal and state legislature. A narrative review method was utilized to examine the existing literature on this paradoxical effect. Keywords based on Medical Subject Headings (MeSH) used to search resources for relevant studies included: Hispanic health paradox (health paradox, immigrant paradox), ethnic minorities (Latinos, LatinX), health disparities (disproportionate health, health inequities), social justice (healthcare stakeholders, health inequities solutions, inequities recommendations), mental health, physical health, and co-morbidities. A quality assessment of full-text peer-reviewed articles yielded 80 articles to compile this narrative review. The research revealed that, despite glaring disparities in social determinants of health, Hispanic Americans have overall experienced better health outcomes through a culture that emphasizes spirituality, community support, and strong family ties.

The purpose of this study is to find the best protocol to reduce the X-ray dose to the eye lens during head diagnostic computed tomography (CT) without decreasing image quality in the organs of interest according to the type of scanner. The lens of the eye is one of radiosensitive tissues in the body. Radiation induced cataract has been demonstrated among staff involved in interventional procedures using X-rays. This study compares the absorbed dose and image quality of several dose reduction technics to the eye lens during head CT exam namely bismuth shielding, organ-based dose modulation, tube current modulation, tube voltage modulation and the combination of a number of these techniques. Compared to the reference scan (Fixed tube current without bismuth shielding), the dose to the eye lens was reduced by 29.91% with bismuth shield, 14.55% with tube current modulation, 37.76% with tube current modulation and bismuth shield. The combination of organ-based dose modulation with tube voltage modulation reduced the dose by 44.93% that of tube current modulation with tube voltage modulation reduced by 19.03% and that of tube current modulation with tube voltage modulation and shield by 46.73%.
The combination of organ-based dose with tube voltage modulation provided superior image quality than that of tube current modulation with tube voltage modulation and shield while similarly reducing dose to the eye lens.

Published: December 2021

OBJECTIVE- FNAC is an accurate and rapid technique for diagnosing pancreatic masses. Pancreatic carcinoma represents the seventh leading cause of cancer death in the world, responsible for more than 300,000 deaths per year.[1] Worldwide, both the incidence and death rates of pancreatic cancer are increasing. The aim of this study was early diagnosis of these lesions and to evaluate its burden and study the global, regional, and national patterns. These would further aid in policy making , better resource allocation for controlling pancreatic cancer risk factors and formulating more effective treatments.[2]
METHODS- This was a retrospective observational study performed at a tertiary care hospital over a period of one and a half year. A total of 86 patients with pancreatic lesions were subjected to image guided FNA . 35 of these patients underwent diagnostic histopathology in addition to FNA.
RESULTS- The 86 cases analyzed were in the age group of 61-70 years with mean age distribution of 57.34 years. Male predominance was seen with M:F ratio of 2.18:1. Head was the most common area to be aspirated followed by tail and least number of lesions were in body of pancreas. Maximum cases were found to be malignant (55) in etiology. Only 2 were non diagnostic because one of them had insufficient cellularity and other had necrosis mainly on histopathology. Adenocarcinoma was the most common malignancy found followed by one case each of lymphoma and solid pseudo papillary neoplasm of pancreas. Histo pathological correlation was obtained in 91.42% cases proving that FNA is a very useful tool in early diagnosing pancreatic lesions.
Iambic verse in different literary traditions
Authors: Kazartsev Еvgeny 
Published: December 2021

Abstract
This paper is devoted to study how the metrical verse like iambic tetrameter can be realized in different literary traditions. The formation of iambic verse in the Early Modern Time in Europe and its spread to the East of the Continent is investigated. The interaction between meter and language in different literary traditions during this process is considered and the nature of the meter’s implementation is determined. As a result of the transfer of iambic verse from one tradition to another, the highest degree of correspondence between meter and language is achieved. The utmost level of verse metricality was especially successfully embodied in the German and later also in the early Russian iambic poetry. However, the evolution and the further transfer of iamb on the East of the Continent significantly modifies the principles of interaction between metrical canon and language prosody.

Published: December 2021

Abstract
It is essential to analyse the dielectric performance in a humid environment of insulating liquids of plant origin, considered as alternatives to mineral oil (MO) which is not environmentally friendly. This paper focuses on the effects of different moisture levels on the dielectric strength and partial discharge initiation voltage of two natural monoesters, based on castor oil (CO) and palm kernel oil (PKO), and MO. The different samples were moistened with a glycerol solution, then sealed and stored for 12 days to allow further diffusion of moisture into the samples. Dielectric strength was statistically evaluated from IEC 60156. Partial discharge inception voltage (PDIV) experiment was performed in conformity with a modified IEC 61294 purpose at ambient temperature. Based on the experimental observations, the moisture has different behavior on dielectric strength and PDIV of insulating oils. Monoesters have a better withstand to water contamination than MOs in power transformers.
A comparison of spoken and signed lingua franca communication: the case of English as a lingua franca (ELF) and International Sign (IS)
Authors: Bierbaumer Lisa 
Published: December 2021

AbstractThis article explores similarities between English as a lingua franca (ELF) and International Sign (IS), two lingua franca phenomena which in the last decades have been subject to increasing, albeit independent, linguistic research. In contrast to spoken intercultural communication, in which English often represents a shared resource that speakers from different linguacultural backgrounds draw on, in the visual-gestural modality no specific sign language has yet gained such global reach. Instead, in many international contexts IS is used: a lingua franca that can be more or less conventionalized and that is not based on one particular sign language. IS use depends on the communicative situation, in which signers flexibly and creatively use different signs from natural sign languages as well as iconic elements and gestures. Despite overt formal differences between ELF and IS, when focusing on the actual communication process, rather than the forms that result from it, the two lingua franca phenomena share many similarities. In fact, both ELF and IS are variable communicative means that get situationally adapted by speakers and signers on the basis of different resources they have at their disposal. Similar discussions about the difficulty of conceptualizing ELF and IS, about the role of multilingual resources, and about interaction processes at play can thus be found in both ELF and IS literature. This insight opens up new possibilities for researchers in the two fields to mutually benefit from the study of lingua franca communication in the other modality, which prompts the need for a cross-modal collaboration between ELF and IS researchers.
TED talks: multimodal communicative affordances for EPS/ELF dissemination
Authors: García-Sánchez Soraya 
Published: December 2021

AbstractTalks have been of interest for researchers who have compared different modes of scientific speeches such as traditional formal lectures, conferences and storyboarding technology, entertainment, and design (TED) talks. This article aims at exploring effective approaches to knowledge dissemination for non-native speakers in English Public Speaking (EPS) scenarios, a current challenge for international university students or academics, who need to adapt the format of the lecture or conference to a more persuasive and engaging public speech. TED Talks allow information consumers either in real time halls or in ubiquitous online performances to listen to well-explained verbal ideas that connect nonverbal language and emotions with the international audience. The hypothesis, therefore, is that TED Talks can serve as models of multimodal dissemination pitches to English as a Lingua Franca (ELF) speakers, who can be trained to improve their speech performance and convey their scientific notions and results successfully. After analysing the 10 most popular TED Talks, the findings suggest a set of strategies and techniques that can be useful for non-native learners in English Public Speaking contexts or for users of English as a Lingua Franca in their dissemination talks. The results provide some common pedagogical affordances for ELF dissemination talks, considering multimodal and nonverbal communication.

AbstractObjectivesThe possibility to isolate fetal cells from pregnant women cervical samples has been discussed for five decades but is not currently applied in clinical practice. This study aimed at offering prenatal genetic diagnosis from fetal cells obtained through noninvasive exocervical sampling and immuno-sorted based on expression of HLA-G.MethodsWe first developed and validated robust protocols for cell detection and isolation on control cell lines expressing (JEG-3) or not (JAR) the HLA-G antigen, a specific marker for extravillous trophoblasts. We then applied these protocols to noninvasive exocervical samples collected from pregnant women between 6 and 14 weeks of gestational age. Sampling was performed through insertion and rotation of a brush at the ectocervix close to the external os of the endocervical canal. Finally, we attempted to detect and quantify trophoblasts in exocervical samples from pregnant women by ddPCR targeting the male SRY locus.ResultsFor immunohistochemistry, a strong specific signal for HLA-G was observed in the positive control cell line and for rare cells in exocervical samples, but only in non-fixative conditions. HLA-G positive cells diluted in HLA-G negative cells were isolated by flow cytometry or magnetic cell sorting. However, no HLA-G positive cells could be recovered from exocervical samples.SRYgene was detected by ddPCR in exocervical samples from male (50%) but also female (27%) pregnancies.ConclusionsOur data suggest that trophoblasts are too rarely and inconstantly present in noninvasive exocervical samples to be reliably retrieved by standard immunoisolation techniques and therefore cannot replace the current practice for prenatal screening and diagnosis.
Ecolinguistics: A half-century overview
Authors: Zhou Wenjuan 
Published: December 2021

Abstract
The last 50 years have witnessed ecolinguistics come into bloom as a mature domain. This paper aims to examine the half-century development of ecolinguistics by reviewing its backgrounds, definitions, strands, and approaches, and also briefly previewing its future horizons. The birth of ecolinguistics can be attributed to such ecological necessities as the ecological crisis as an essential root, and an ecological perspective for linguistics as a linguistic necessity, together with six ecolinguistic turns in this domain (Section 2). Since the emergence of ecolinguistics in the 1970s, various definitions for ecolinguistics as an evolving concept have come into being, involving the geographical, conceptual, disciplinary, methodological, and practical sides (Section 3). Figures who have contributed to the development of this domain can be divided into old strands like Haugenian and Hallidayan ecolinguistics, as well as new strands such as strong ecolinguistics and the latest radical embodied ecolinguistics (Section 4). Given the diverse definitions and strands, a set of approaches have taken shape, ranging from the Haugenian approach to ecological discourse analysis (Section 5). Due to major problems found in reviewing four parts of ecolinguistics, it is high time three shifts in perspective be put into effect in ecolinguistics that can promise its future horizons.
Growth and yield of potato (Solanum tuberosum L.) as affected by storage conditions and storage duration in Jos, Plateau State, Nigeria

Published: January 2022

Abstract
This study was carried out in two seasons (2010–2011 and 2012–2013) in Jos, Plateau State, Nigeria to investigate the growth and yield of potato (Solanum tuberosum L.) seed tubers as affected by storage conditions and storage duration. Five potato varieties (“Nicola,” “Bertita,” “Diamant,” “BR63-18,” and “Roslin-Ruaka”) were stored for three durations (12, 24, and 32 weeks) in three kinds of stores (room temperature store [RTS], diffused light store [DLS], and air-conditioned store [ACS]). The experimental design was a split–split plot in a randomized complete block design with the potato varieties, storage conditions, and storage durations as the main, sub, and sub–sub plots, respectively. All the parameters assessed varied with variety except the plant height. Germination and establishment were significantly higher in ACS than in RTS and DLS. RTS and DLS resulted in more aboveground stems than ACS. Storage in ACS resulted in a significantly higher plant height, leaf number, total number and yield of tubers, and yield of saleable tubers in both seasons. Seed tubers stored for 24 weeks resulted in the highest establishment count and the mean number of aboveground stems in both seasons. Aboveground stems increased from 12 to 24 weeks of storage and declined at 32 weeks. Seed storage for 12 weeks resulted in the highest total number of tubers, whereas 32 weeks had the lowest number of tubers in both seasons. Seed storage for 12 and 32 weeks resulted in the highest yield of tubers in seasons 1 and 2, respectively. In conclusion, potato varieties varied greatly in the rate of physiological aging; hence, every variety required specific storage conditions and duration for optimal growth and yield.

Abstract
The enhanced principal rank characteristic sequence (epr-sequence) of a symmetric matrix B ∈ 𝔽
n×n
is defined as ℓ1ℓ2· · · ℓ
n
, where ℓ
j
∈ {A, S, N} according to whether all, some but not all, or none of the principal minors of order j of B are nonzero. Building upon the second author’s recent classification of the epr-sequences of symmetric matrices over the field 𝔽 = 𝔽2, we initiate a study of the case 𝔽= 𝔽3. Moreover, epr-sequences over finite fields are shown to have connections to Ramsey theory and coding theory.
Spectra inhabiting the left half-plane that are universally realizable
Authors: Soto Ricardo L. 
Published: December 2021

Abstract
Let Λ = {λ1, λ2, . . ., λ
n
} be a list of complex numbers. Λ is said to be realizable if it is the spectrum of an entrywise nonnegative matrix. Λ is universally realizable if it is realizable for each possible Jordan canonical form allowed by Λ. Minc ([21],1981) showed that if Λ is diagonalizably positively realizable, then Λ is universally realizable. The positivity condition is essential for the proof of Minc, and the question whether the result holds for nonnegative realizations has been open for almost forty years. Recently, two extensions of the Minc’s result have been proved in ([5], 2018) and ([12], 2020). In this work we characterize new left half-plane lists (λ1 > 0, Re λ
i
≤ 0, i = 2, . . ., n) no positively realizable, which are universally realizable. We also show new criteria which allow to decide about the universal realizability of more general lists, extending in this way some previous results.
