Published: November 2020

Background The coronavirus disease (COVID-19) pandemic is a highly infectious viral disease that has spread to over one hundred and eight countries, including Nigeria. Governments across the globe have been implementing preventive measures towards curbing the spread and impact of the virus. These measures have continued to interfere with the general lifestyle of the people. Hence, this study was aimed at examining the socio-demographic predictors of adherence to prescribed recommendations and the psychological impacts of COVID-19 pandemic lockdown among Nigerian social media users. Methods: This research implemented a cross-sectional survey using an online Google-based questionnaire to elicit required information from potential respondents via social media channels such as WhatsApp, Twitter, Instagram, Telegram and Facebook. An external link to the questionnaire was shared among Nigerian social media users between 1st and 31st April 2020, and a total of 1,131 respondents participated in the survey. The explanatory and outcome variables were displayed by frequency and percentage distribution while chi-square analysis was used to show the relationship between the explanatory and outcome variables at 5% level of significant. Results The study showed that 99% of the respondents reported to have been following some of the prescribed recommendations, however, only 40.4% of the respondents followed all the recommendations. More than three fifths (63.4%) of the respondents also reported having experienced stressed during the lockdown. Only respondents’ professional background (p<0.05) was a predictor of psychological impact of lockdown, other selected socio-demographic characteristics were not predictors of the outcome variables as p>0.05 Conclusion We concluded that majority of Nigerian social media users were complying to the prescribed recommendations and that younger age group, female respondents and respondents who are more educated had higher proportion of psychological impacts of lockdown, while the medical/scientific background is the only socio-demographic predictor of psychological impacts of COVID-19 lockdown.
Processes and the Terms of Identification and Defense
Authors: Ksenofontova Elena 
Published: November 2020

The article outlines the semantic field of the problems related to "identity" in order to find a general framework for joint work of narrow specialists studying the social reality that is diverse, yet common to all of us. The main thesis of the paper is that the identification process carried out by the subject in search of self-identification or "I" is not limited to, but is based on the psychological security of the individual. The issue is considered from the point of view of different research disciplines. Pedagogical and Developmental Psychology, as well as Pedagogy deal with the processes of the child’s socialization resulting in his/her mastering the social roles, but also the person’s self-identification as a subject of social relations. The potential capabilities of this subject depend on his/her achievement of self-acceptance based on the feeling of belonging to such a group that offers the values that the person is willing to realize in his/her life. Both psychologists and political scientists indicate considerable difficulties the person comes across on this path.

The 'Royal Journey of Succession to Portugal' of King D. Filipe I of Portugal and the architectonic renovation of the palatine residences: the case of the Royal Palace of Lisbon (Paço da Ribeira)
Authors: Dias Pacheco Milton Pedro 
Published: November 2020

Durante el Viaje Real de Sucesión a Portugal, emprendido en Madrid en marzo de 1580 y terminado en Lisboa en febrero de 1583, el rey español Felipe II se convirtió en D. Filipe I de Portugal. Pero esta expedición política, que tendría como resultado la legitimación del nuevo rey ante el antiguo reino, asumiría serias repercusiones en el ámbito de la arquitectura palatina, con la renovación de un importante conjunto de palacios reales pertenecientes a la Corona portuguesa, integrados desde entonces en la Monarquía Ibérica Dual.
El análisis detallado de las fuentes documentales coetáneas, con énfasis en la correspondencia epistolar producida dentro del círculo del Rey-Prudente, directa o indirectamente, permite comprender los procedimientos iniciales implementados para la renovación arquitectónica y la expansión espacial del principal palacio real portugués en Lisboa: el Paço da Ribeira. Las dimensiones políticas y simbólicas otorgadas al edificio del palacio, hechas en una escala de poder y una imagen de fuerza del propio Rey, deben analizarse en el contexto de la materialización de un gobernante que inevitablemente dejaría el reino pero no a su gente.
The Linguistic Image of the World and Image Schemas: an attempt at their delimitation and comparison
Authors: Carisio Anastasiia 
Published: November 2020

This article is a review of a few essential aspects of one of the famous Slavic linguistic schools —the Polish ethnolinguistic school of Lublin. This school developed the theory of językowy obraz świata (in Polish) or jazykovaja kartina mira (in Russian), which is generally translated in English as ‘Linguistic Image of the World’ (LIW). The Linguistic Image of the World takes into account the sociocultural embeddedness of language and cognition. We will compare this theory with embodiment models —Image Schemas.
The paper is organised in four parts: (1) a brief review of relevant studies related to the Theory of Linguistic Image of the World; (2) an introduction to some essential aspects of Image Schemas, as representative of the standard Cognitive Linguistics approach, together with a brief analysis of some examples; (3) a description of LIW, highlighting some basic notions such as the stereotype and clarifying its relationship with the prototype; and (4) conclusions on the central role of culture in the process of conceptualization.
A signature of tumor DNA repair genes associated with the prognosis of surgically-resected lung adenocarcinoma

Published: November 2020

Background
Lung cancer has the highest morbidity and mortality of cancers worldwide. Lung adenocarcinoma (LUAD) is the most common pathological subtype of lung cancer and surgery is its most common treatment. The dysregulated expression of DNA repair genes is found in a variety of cancers and has been shown to affect the origin and progression of these diseases. However, the function of DNA repair genes in surgically-treated LUAD is unclear.

Methods
We sought to determine the association between the signature of DNA repair genes for patients with surgical LUAD and their overall prognosis. We obtained gene expression data and corresponding clinical information of LUAD from The Cancer Genome Atlas (TCGA) database. The differently expressed DNA repair genes of surgically-treated LUAD and normal tissues were identified using the Wilcoxon rank-sum test. We used uni- and multivariate Cox regression analyses to shrink the aberrantly expressed genes, which were then used to construct the prognostic signature and the risk score formula associated with the independent prognosis of surgically-treated LUAD. We used Kaplan–Meier and Cox hazard ratio analyses to confirm the diagnostic and prognostic roles. Two validation sets (GSE31210 and GSE37745) were downloaded from the Gene Expression Omnibus (GEO) and were used to externally verify the prognostic value of the signature. OSluca online database verifies the hazard ratio for the DNA repair genes by which the signature was constructed. We investigated the correlation between the signature of the DNA repair genes and the clinical parameters. The potential molecular mechanisms and pathways of the prognostic signature were explored using Gene Set Enrichment Analysis (GSEA).

Results
We determined the prognostic signature based on six DNA repair genes (PLK1, FOXM1, PTTG1, CCNO, HIST3H2A, and BLM) and calculated the risk score based on this formula. Patients with surgically-treated LUAD were divided into high-risk and low-risk groups according to the median risk score. The high-risk group showed poorer overall survival than the low-risk group; the signature was used as an independent prognostic indicator and had a greater prognostic value in surgically-treated LUAD. The prognostic value was replicated in GSE31210 and GSE37745. OSluca online database analysis shows that six DNA repair genes were associated with poor prognosis in most lung cancer datasets. The prognostic signature risk score correlated with the pathological stage and smoking status in surgically-treated LUAD. The GSEA of the risk signature in high-risk patients showed pathways associated with the cell cycle, oocyte meiosis, mismatch repair, homologous recombination, and nucleotide excision repair.

Conclusions
A six-DNA repair gene signature was determined using TCGA data mining and GEO data verification. The gene signature may serve as a novel prognostic biomarker and therapeutic target for surgically-treated LUAD.

Published: November 2020

Background
The coronavirus 19 (COVID-19) pandemic has heightened the threat to the health and lives of patients with comorbid diseases. Infection by COVID-19 is especially detrimental to patients on hemodialysis. In this study, we evaluated the clinical characteristics, laboratory findings, treatments and prognoses of hemodialysis patients with COVID-19.

Methods
A total of 16 hemodialysis patients with COVID-19 were recruited from Wuhan Fourth Hospital from 5 February to 20 March 2020 for a retrospective, single-center study. A total of 62 non-dialysis patients with COVID-19 were the control group. We collected data on the clinical characteristics, laboratory findings, treatments, and clinical outcomes of patients affected by the virus.

Results
Hemodialysis patients with COVID-19 had a lower incidence of fever (P = 0.001) and relatively higher incidence of pre-admission comorbidities and shortness of breath than non-dialysis patients with COVID-19 (75% vs. 61%, P = 0.467 50% vs. 33.87%, P = 0.248 ). Hemodialysis patients had lower levels of hemoglobin (P < 0.001), white blood cell counts (P = 0.015), neutrophils (P = 0.016), AST (P = 0.037), ALT (P < 0.001) and procalcitonin (P < 0.001), and higher levels of D-dimer (P < 0.001) and thrombin time (P < 0.001). Hemodialysis patients had a higher incidence of pulmonary effusion, cord-like high-density shadows, pleural thickening, and atelectasis (P < 0.05). Hemodialysis patients also had relatively higher rates of mortality and prolonged hospital stays compared with the control group.

Conclusions
Hemodialysis patients typically present with multiple comorbidities and are considered to be a high-risk group for COVID-19 infections. Hemodialysis patients with COVID-19 may have prolonged hospital stays and unfavorable prognoses and should be closely monitored.

Published: November 2020

AbstractOptical magnetometers with high resolution, integrability, and reconfigurability have been central to the development of advance photonic devices for remote and efficient magnetic field sensing. These magnetometers have mostly been based on ferromagnetic materials that detect only static magnetic fields. Here, the limitation is overcome by utilizing an interferometric technique to demonstrate a reconfigurable fiber‐based magnetometer that is highly sensitive to both static and dynamic magnetic fields. The proposed sensor shows an unprecedented sensitivity of 37.07 nm/mT for static magnetic field that could enable detection of few nanotesla fields with a high‐resolution optical spectrometer. Furthermore, the proposed magnetometer has wide dynamic range extending over a frequency band of 0–1700 Hz with significant signal to noise ratio (16.04 dBm at 615 Hz) that enables precise frequency determination of the signal. The large reconfigurability, dynamic operation frequency, and portability of the demonstrated magnetometer ascertain practical applications in broad range of technologies including cardiovascular health monitoring, underground mineral exploration, and marine surveillance.
Lack of Photon Antibunching Supports Supertrap Model of Photoluminescence Blinking in Perovskite Sub‐Micrometer Crystals

Published: November 2020

AbstractAntibunching effect is typically observed in individual systems possessing photoluminescence (PL) blinking and vice versa. Contrary to this common perception, absence of antibunching in strongly blinking methyl ammonium led tri‐iodide (MAPbI3) perovskite crystals of sizes from tens to hundreds of nanometers regardless of the excitation power density is observed. Antibunching effect does not appear even when photon statistics are analyzed for bright and intermediate PL intensity levels independently. This shows that there is no directional energy funneling and accumulation of charge carriers in the small local regions in MAPbI3 crystals where an Auger recombination can potentially suppress the simultaneous emission of two photons. This result allows for the exclusion of the PL blinking mechanism based on the idea of emitting sites previously hypothesized for perovskites. Therefore, the model of PL blinking in perovskite crystals based on the presence of a metastable non‐radiative recombination center (the supertrap) is the only one proposed so far which explains blinking without conflicting with the absence of photon correlations.
What Governs Pickering Emulsion Properties During Preparation via Batch Rotor‐Stator Homogenizers?
Authors: Kempin Maresa Vivien , Drews Anja 
Published: November 2020

AbstractPickering emulsions have received increasing interest in many fields of application recently. In designing Pickering emulsion properties, focus is typically laid on composition whereas the preparation process as another possible leverage is not considered in detail. Here, Pickering emulsions of constant composition were prepared using two dispersing heads of a rotor‐stator homogenizer and compared in terms of Sauter mean diameters and rheology. It was found that the ratio of tip speed and gap width between rotor and stator is a better correlating parameter than tip speed only.
Comparing Efficiency per Volume of Uniflow Cyclones and Standard Cyclones
Authors: Muschelknautz Ulrich 
Published: November 2020

AbstractA competitive alternative to the standard reverse flow cyclone for gas‐solids separation is the uniflow cyclone. Gas and particles passing through it in only one direction, allowing a cost‐effective usage in space limited applications. Comprehensive studies of uniflow cyclones have strongly improved their understanding and led to approved design criteria and calculation methods. Here it is shown that uniflow cyclones can achieve higher efficiencies per volume with a low pressure drop than standard cyclones.
Trait coordination and environmental filters shape functional trait distributions of forest understory herbs
Authors: Candeias Matt , Fraterrigo Jennifer 
Published: November 2020

Abstract

Understanding the drivers of trait selection is critical for resolving community assembly processes. Here, we test the importance of environmental filtering and trait covariance for structuring the functional traits of understory herbaceous communities distributed along a natural environmental resource gradient that varied in soil moisture, temperature, and nitrogen availability, produced by different topographic positions in the southern Appalachian Mountains.

To uncover potential differences in community‐level trait responses to the resource gradient, we quantified the averages and variances of both abundance‐weighted and unweighted values for six functional traits (vegetative height, leaf area, specific leaf area, leaf dry matter content, leaf nitrogen, and leaf δ13C) using 15 individuals of each of the 108 species of understory herbs found at two sites in the southern Appalachians of western North Carolina, USA.

Environmental variables were better predictors of weighted than unweighted community‐level average trait values for all but height and leaf N, indicating strong environmental filtering of plant abundance. Community‐level variance patterns also showed increased convergence of abundance‐weighted traits as resource limitation became more severe.

Functional trait covariance patterns based on weighted averages were uniform across the gradient, whereas coordination based on unweighted averages was inconsistent and varied with environmental context. In line with these results, structural equation modeling revealed that unweighted community‐average traits responded directly to local environmental variation, whereas weighted community‐average traits responded indirectly to local environmental variation through trait coordination.

Our finding that trait coordination is more important for explaining the distribution of weighted than unweighted average trait values along the gradient indicates that environmental filtering acts on multiple traits simultaneously, with abundant species possessing more favorable combinations of traits for maximizing fitness in a given environment.

Published: November 2020

AbstractWith the development of wireless mobile network and Internet of Things (IoT), users enter the network with a large amount of data and information, including some important personal information, such as ID number, telephone number. Personal privacy disclosure has become one of the focuses of attention. In this article, we propose an asymmetric group key agreement (GKA) protocol based on attribute threshold for IoT to protect user privacy. Users do not need to expose any personal information in the group, but only need to meet the same number of attributes and conduct bidirectional authentication registration with key generation center (KGC) to ensure the legitimacy of mobile terminal members participating in GKA. In the registration phase, user performs heavy preliminary calculations according to the designed protocol, thereby reducing the computation in the key agreement phase and decreasing the complexity of the protocol. The protocol can realize self‐verification, and any member participating in key agreement can verify the correctness of the negotiated key by themselves. Under the assumption of bilinear computational Diffie‐Hellman problem, the security of the protocol is proved. Performance analysis further shows that our protocol has lower energy consumption in terms of communication and computing.
