What gives a stroke publication impact? Assessing traditional and alternative metrics of scientific impact for papers published in the journal Stroke
Authors: Wong Li Siang , Drozdowska Bogna A , Doherty Daniel , Quinn Terence J 
Published: March 2021

Background: The ‘impact’ of a scientific paper is a measure of influence in its field. In recent years, traditional, citation-based measures of impact have been complemented by Altmetrics, which quantify social media footprint. As authors and research institutions seek to increase their visibility both within and beyond the academic community, it is important to identify and compare the determinants of traditional and alternative metrics. We explored this using Stroke – a leading journal in its field. Methods: We described the impact of original research papers published in Stroke (2015-2016) using citation count and Altmetric Attention Score (Altmetrics). Using these two metrics as our outcomes, we assessed univariable and multivariable associations with 21 plausibly relevant publication features. We set the significance threshold at p<0.01. Results: Across 911 papers published in Stroke, there was an average citation count of 21.60 (±17.40) and Altmetric score of 17.99 (±47.37). The two impact measures were weakly correlated (r=0.15, p<0.001). Citations were independently associated with five publication features at a significance level of p<0.01: Time Since Publication (beta=0.87), Number of Authors (beta=0.22), Publication Type (beta=6.76), Number of Previous Publications (beta=0.01) and Editorial (beta=9.45). For Altmetrics, we observed a trend for independent associations with: Time Since Publication (beta=-0.25, p=0.02), Number of References (beta=0.32, p=0.02) and Country of Affiliation (beta=8.59, p=0.01). Our models explained 21% and 3% of variance in citations and Altmetrics, respectively. Conclusion: Papers published in Stroke have impact. Certain aspects of content and format may contribute to impact, but these differ for traditional measures and Altmetrics, and explain only a very modest proportion of variance in the latter. Citation counts and Altmetrics seem to represent different constructs and, therefore, should be used in conjunction to allow a more comprehensive assessment of publication impact.
Systemic inflammation is negatively associated with early post discharge growth following acute illness among severely malnourished children - a pilot study

Published: March 2021

Background: Rapid growth should occur among children with severe malnutrition (SM) with medical and nutritional management. Systemic inflammation (SI) is associated with death among children with SM and is negatively associated with linear growth. However, the relationship between SI and weight gain during therapeutic feeding following acute illness is unknown. We hypothesised that growth post-hospital discharge is associated with SI among children with SM. Methods: We conducted secondary analysis of data from HIV-uninfected children with SM (n=98) who survived and were not readmitted to hospital during one year of follow-up. We examined the relationship between changes in absolute deficits in weight and mid-upper-arm circumference (MUAC) from enrolment at stabilisation to 60 days and one year later, and untargeted plasma proteome, targeted cytokines/chemokines, leptin, and soluble CD14 using multivariate regularized linear regression. Results: The mean change in absolute deficit in weight and MUAC was -0.50kg (standard deviation; SD±0.69) and -1.20cm (SD±0.89), respectively, from enrolment to 60 days later. During the same period, mean weight and MUAC gain was 3.3g/kg/day (SD±2.4) and 0.22mm/day (SD±0.2), respectively. Enrolment interleukins; IL17-alpha and IL-2, and serum amyloid P were negatively associated with weight and MUAC gain during 60 days. Lipopolysaccharide binding protein and complement component 2 were negatively associated with weight gain only. Leptin was positively associated with weight gain. Soluble CD14, beta-2 microglobulin, and macrophage inflammatory protein 1 beta were negatively associated with MUAC gain only. Glutathione peroxidase 3 was positively associated with weight and MUAC gain during one year. Conclusions: Early post-hospital discharge weight and MUAC gain were rapid and comparable to children with uncomplicated SM treated in the community. Higher concentrations of SI markers were associated with less weight and MUAC gain, suggesting inflammation negatively impacts recovery from wasting. This finding warrants further research on reducing inflammation on growth among children with SM.
Photoacoustic imaging in monitoring of compartmental syndrome in rat extremities
Authors: Li Caiyun , Du Feiya , Zhou Haiying , Lu Hui 
Published: March 2021

Muscle ischemia injury is the essence of compartment syndrome (CS). Photoacoustic (PA) imaging can monitor hemoglobin concentration changes in ischemic tissue by determining the state of light-absorbing molecules. This study investigated whether PA imaging can provide accurate CS monitoring. Rats received compression on the lower hind limb for 3 h to induce ischemia injury, followed by PA imaging of desired muscles for 24 h. PA intensities of the injured group were significantly lower than that in the control group. Histology findings correlated well with the PA findings. The results demonstrated that PA imaging could be a noninvasive and timely tool for clinically monitoring CS.
RETRACTED: Ultra-wideband terahertz absorber based on graphene modulation
Authors: Li Xiaogang , Feng Guang , Lin Suben 
Published: March 2021

Here we propose an ultra-wideband terahertz absorber (UWTA), which is
composed of substrate, dielectric, and five-layer graphenes. By
changing the chemical potential of graphene, the absorption
coefficient of UWTA is larger than 0.9 from 1.51–8.25 THz. The
absorption bandwidth is 6.74 THz. The relative bandwidth is 138.1%,
and the modulation depth is 78.7%. Meanwhile, the number of each layer
of graphene can be adjusted to achieve high absorption bandwidth,
relative bandwidth, and modulation depth. Besides, due to the tunable
chemical potential of graphene, the absorption coefficient can be
adjusted to make up the manufacturing error.
Dependence of conduction characteristics on compensation type and lattice structure of SiC photoconductive semiconductor switches
Authors: Feng Zhuoyun , Xiao Longfei , Luan Chongbian , Li Yangfan , Sha Huiru , Li Hongtao , Xu Xiangang 
Published: March 2021

Semi-insulating (SI) SiC photoconductive semiconductor switches were prepared using two compensation mechanisms: namely vanadium dopants compensation (4H- and 6H-SiC) and deep level defect compensation (4H-SiC). The bias voltage and current of the high-purity (HP) SI 4H-SiC photoconductive semiconductor switch (PCSS) with a channel length of 1 mm reached 24 kV and 364 A, respectively, and the minimum on-state resistance of approximately 1 Ω was triggered by laser illumination at a wavelength of 355 nm. The experimental results show that, in this case, the on-state characteristics of HP 4H-SiC PCSS are superior to those of the vanadium-doped(VD) 4H and 6H-SiC PCSS devices. HP 4H-SiC PCSS shows remarkable waveform consistency. Unlike for VD 4H and 6H-SiC PCSS, the current waveform of HP 4H-SiC PCSS exhibits a tailing phenomenon due to its longer carrier lifetime.
Bedeutung der psychologischen Sicherheit für die Innovationsfähigkeit von Organisationen
Authors: Hoffmann Bettina , Hanisch Dominik 
Published: March 2021

AbstractThe future of a company depends to a large extent on whether it can establish market-relevant innovations. In order to develop innovations and thus build sustainable business models, companies should operate their own innovation management. This not only systematically develops innovations, it also creates organizational framework conditions so that an innovative company culture can flourish better. But not only the organizational aspects lead to an increased ability to innovate, it is also the interpersonal interactions that make a decisive contribution. The quality and the result of human interaction depends in a decisive way on how safe people feel in the current group setting. The more confident they feel, the more the group members dare to ask questions, admit weaknesses and mistakes, contribute ideas and question the status quo - the foundations for innovation. If a company wants to develop the basis for psychological safety, then it is important to create suitable conditions in order to be able to make full use of the performance potential of all employees. Freedom, trust and participation are particularly important in innovation in order to promote creativity and the ability to innovate.
Running it up the flagpole to see if anyone salutes: A response to Woodward on causal and explanatory asymmetries
Authors: Elliott Katrina , Lange Marc 
Published: March 2021

Does smoke cause fire or does fire cause smoke? James Woodward’s “Flagpoles anyone? Causal and explanatory asymmetries” argues that various statistical independence relations not only help us to uncover the directions of causal and explanatory relations in our world, but also are the worldly basis of causal and explanatory directions. We raise questions about Woodward’s envisioned epistemology, but our primary focus is on his metaphysics. We argue that any alleged connection between statistical (in)dependence and causal/explanatory direction is contingent, at best. The directions of causal/explanatory relations in our world seem not to depend on the statistical (in)dependence relations in our world (conceived of either as frequency patterns or as relations among chances). Thus, we doubt that statistical (in)dependence relations are the worldly basis of causal and explanatory directions.

Authors: Трегубова Наталья Дамировна , Ни Максим Леонидович , Китаева Анастасия Александровна 
Published: March 2021

Миграция в Россию из стран СНГ — явление, которое ставит перед социальными учеными многочисленные исследовательские проблемы. Разнообразие миграционных потоков и трудности в доступе к «полю» приводят к тому, что различные фрагменты общей картины лишь в той или иной степени согласуются друг с другом. Статья посвящена осмыслению и сравнению нескольких таких фрагментов, полученных в ходе изучения «следов» активности транснациональных мигрантов в интернете. Авторы стремятся ответить на два вопроса: какие стороны миграционных процессов проявляются в собранных данных, а какие — ускользают от исследователей; как полученные результаты и их ограничения соотносятся со свойствами онлайн-среды, организованной деятельностью поисковых, классифицирующих и сортирующих алгоритмов? Эмпирический материал представлен двумя типами онлайн-данных, характеризующих миграцию в Россию из пяти стран (Азербайджана, Казахстана, Кыргызстана, Таджикистана и Узбекистана). Это группы "ВКонтакте" и сайты, найденные с помощью поисковика Google.
Данные были собраны на шести языках: русском и стран исхода. В качестве методов выступают сетевой анализ, контент-анализ, а также онлайн-наблюдение. Охарактеризованы процессы сбора и анализа данных и основные результаты исследования для каждого из методов. Результаты соотнесены друг с другом, сделаны выводы о содержательных характеристиках миграционных процессов и о возможностях и ограничениях исследования миграции в онлайн-среде. Авторы описывают «разделение труда» между людьми и алгоритмами на каждом из этапов исследования, выделяют три типа алгоритмов согласно их роли в исследовательском процессе, а также размышляют над тем, как принятые методологические решения повлияли на полученные результаты.

Characteristic cycle and wild ramification for nearby cycles of étale sheaves
Authors: Hu Haoyu , Teyssier Jean-Baptiste 
Published: March 2021

Abstract
In this article,
we give a bound for the wild ramification of the monodromy action on the nearby cycles complex of a locally constant étale sheaf on the generic fiber of a smooth scheme over an equal characteristic trait in terms of Abbes and Saito’s logarithmic ramification filtration. This provides a positive answer to the main conjecture in [24] for smooth morphisms in equal characteristic. We also study the ramification along vertical divisors of étale sheaves on relative curves and abelian schemes over a trait.
Designing Strategic Games with Preestablished Nash Equilibrium through Artificial Inference and Global Learning
Authors: e Oliveira Jr. Hime A. 
Published: March 2021

Abstract
This work presents novel results obtained by the application of global optimization techniques to the design of finite, normal form games with mixed strategies. To that end, the Fuzzy ASA global optimization method is applied to several design examples of strategic games, demonstrating its effectiveness in obtaining payoff functions whose corresponding games present a previously established Nash equilibrium. In other words, the game designer becomes able to choose a convenient Nash equilibrium for a generic finite state strategic game and the proposed method computes payoff functions that will realize the desired equilibrium, making it possible for the players to reach the favorable conditions represented by the chosen equilibrium. Considering that game theory is a very useful approach for modeling interactions between competing agents and Nash equilibrium represents a powerful solution concept, it is natural to infer that the proposed method may be very useful for strategists in general. In summary, it is a genuine instance of artificial inference of payoff functions after a process of global machine learning, applied to their numerical components.
Circular RNA–MicroRNA–MRNA interaction predictions in SARS-CoV-2 infection
Authors: Demirci Yılmaz Mehmet , Saçar Demirci Müşerref Duygu 
Published: March 2021

Abstract
Different types of noncoding RNAs like microRNAs (miRNAs) and circular RNAs (circRNAs) have been shown to take part in various cellular processes including post-transcriptional gene regulation during infection. MiRNAs are expressed by more than 200 organisms ranging from viruses to higher eukaryotes. Since miRNAs seem to be involved in host–pathogen interactions, many studies attempted to identify whether human miRNAs could target severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNAs as an antiviral defence mechanism. In this work, a machine learning based miRNA analysis workflow was developed to predict differential expression patterns of human miRNAs during SARS-CoV-2 infection. In order to obtain the graphical representation of miRNA hairpins, 36 features were defined based on the secondary structures. Moreover, potential targeting interactions between human circRNAs and miRNAs as well as human miRNAs and viral mRNAs were investigated.
Antenatal depression and anxiety during the COVID-19 pandemic: a cross-sectional study in pregnant women from routine health care contact in Greece
Authors: Tsakiridis Ioannis , Dagklis Themistoklis , Mamopoulos Apostolos , Athanasiadis Apostolos , Pearson Rebecca , Papazisis Georgios 
Published: March 2021

Abstract

Objectives
The impact of the COVID-19 pandemic and the public health measures introduced to control it, on mental health, is largely unknown. Research conducted during past epidemics found that pregnant women are more vulnerable psychologically. The aim of this study was to investigate antenatal depressive and anxiety symptoms during this pandemic in Greece.

Methods
All women receiving routine antenatal care, during a three-month period, starting one week after the total lockdown in Greece, in a University department, were asked to fill in two questionnaires, the Edinburg Postnatal Depression Scale (EPDS) and the State-Trait Anxiety Inventory (STAI).

Results
Overall, 505 women (93.3% of the eligible population) agreed to participate. The prevalence of antenatal depression (EPDS score≥13) in the population of the study was 13.5%. Unplanned pregnancy (OR: 2.447; 95% CI: 1.235–4.846), smoking (OR: 2.268; 95% CI: 1.166–4.411) and antenatal anxiety (OR: 5.074; 95% CI: 2.898–8.883) increased the risk of antenatal depression during the COVID-19 pandemic. State (current)-anxiety affected 34.1% of the participants, whereas Trait (lifetime)-anxiety affected 15.8%. The State-anxiety score (median) was significantly higher than the Trait-anxiety (median) (41 vs. 36; p<0.001), revealing an increase in the levels of anxiety in the pandemic, while there was also a positive linear correlation between the two scales (rho=0.592; p<0.001).

Conclusions
The unprecedented situation of the COVID-19 pandemic has increased anxiety, but not depression levels of pregnant women in Greece. Population level interventions to address adverse effects on anxiety status in the initial phases of similar situations may be helpful in the future.
Burkitt-like lymphoma with 11q aberration in a patient with AIDS and a patient without AIDS: Two cases reports and literature review
Authors: Wang Jing , Ma Li , Guo Jianghong , Xi Yanfeng , Xu Enwei 
Published: March 2021

Abstract

Objective
The aim of this study is to evaluate the clinicopathological features and the treatment of the Burkitt-like lymphoma with 11q aberration.

Methods
We reported two patients with Burkitt-like lymphoma with 11q aberration: a 56-year-old man with AIDS (case 1) and a 37-year-old woman (case 2) without AIDS. The biopsy of cervical lymph nodes showed Burkitt-like morphologic and immunophenotypic features. But both of them lack MYC rearrangement and carry an 11q-arm aberration with proximal gains and/or telomeric losses. The diagnosis was confirmed by pathological morphology, immunohistochemistry, and fluorescence in situ hybridization.

Result
After a cycle of R-CTOEP (rituximab, cyclophosphamide, pirarubicin, vincristine, and prednisone) chemotherapy, case 1 refused to chemotherapy and radiotherapy and was followed up for 34 months without recurrence and new focus. Case 2 received R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) for two cycles and achieved PR (partial response). Then, the patient in case 2 received EPOCH (etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin) for three cycles, and the right cervical mass disappeared. She achieved complete response and was followed up for 16 months without recurrence and new focus.

Conclusion
Burkitt-like lymphoma with 11q abnormalities resembles Burkitt lymphoma morphologically but lacks MYC rearrangement and may have a better prognosis.
Visual Assessment for Detection of Diffusion Depth under External Sulfate Attack in Concrete
Authors: Ou Chiqian , Chen Zheng , Yi Chaofan , Boluk Yaman , Bindiganavile Vivek 
Published: March 2021

Abstract
This paper describes two visual approaches, namely an area ratio method and a grayscale variation method, to evaluate the effective diffusion depth inside cement-based systems when subjected to external sulfate attack. The former is based on the calculation of the amount of pixels within two areas, namely the area of cross section and the undiffused area, while the latter is per the normalized color variation. Three types of binder, all conforming to the Canadian Standards Association (CSA), were employed to produce three batches of cylindrical specimens, which were immersed in a sulfate-rich environment for up to 12 wk. The effective diffusion depths, obtained by the two visual approaches described here, were compared with the sulfate content found experimentally through chemical titration. The results show that the proposed visual methods can capture the effective diffusion depths inside cement-based systems after exposure to sulfate attack. The maximum value ranged from 7.0 to 11.0 mm over 12 wk of exposure. The proposed visual techniques enable a quick assessment to decide whether further repair is warranted.
Corrosion Resistance of Low-Temperature and Conventional Plasma-Nitrided 410S Ferritic-Martensitic Stainless Steels
Authors: Varela L. B. , Umemura M. T. , Calderón-Hernández J. W. , Pinedo C. E. , Kolawole F. O. , Tschiptschin A. P. 
Published: March 2021

Abstract
Low-temperature plasma nitriding (LTPN) of 410S ferritic-martensitic stainless steel was carried out in a 75 % N2 – 25 % H2 gas mixture, at 400°C, for 20 h. Conventional plasma nitriding (CPN) was also carried out in the same atmosphere but at 530°C. The corrosion resistance was assessed by potentiodynamic polarization (PP) testing in 3.5-wt. % NaCl. Measuring of the mass loss was carried out after immersion of the specimens in a 3 % FeCl3 solution during 88 h. To define the sensitivity to intergranular corrosion, the degree of sensitization (DOS) was measured using the double-loop electrochemical PP technique (DL-EPR). DL-EPR results indicated that the potentiodynamic-polarization measurements showed that pitting corrosion resistance of the nitrided samples was enhanced, whereas the weight loss experiments showed that LTPN samples presented a corrosion resistance equal to the untreated samples. The DOS results displayed that the untreated samples were less resistant to intergranular corrosion correlated with the LTPN specimens. On the contrary, the CPN specimens exhibited typical behavior of general corrosion.
