Abstract
Tin dioxide (SnO2) thin films have several sorts of applications, including as gas sensors and in photocatalysis, where the surface area plays a relevant role. The use of the Triton X-100 non-ionic surfactant in the precursor solution processing has revealed as a fundamental aid to increase adhesion of the SnO2 film on the substrate. Moreover, the surfactant presence leads to a significant increase in the surface area of deposited thin films, and the roughness (rms) increases from 57.6 nm to 275 nm. The influence can also be observed in the XRD profiles, with a higher degree of crystallinity for Triton deposited films. It also increases the defect density and the electron scattering, leading to rather resistive films which are thermally excited only above room temperature. The activation energy for the defect ionization is rather high, 800 meV, but the thermal excitation takes place at a lower temperature range, compared to films prepared without Triton in the solution processing. The performance on photocatalysis is improved for films prepared with Triton X-100, since most of the methylene blue dye is degraded in the first 90 minutes when interacting with the sample.

Abstract
To improve the mechanical properties and tribological characteristics of boron carbide (SiC) ceramic, silicon carbide as incorporation phase was added into boron carbide (B4C) matrix. The results showed that the incorporation of SiC phase led to denser microstructure and lower porosity. When the content of SiC was 20 wt.%, the composite presented higher bending strength of 447.6MPa and fracture toughness of 7.21 MPa·m1/2. Meanwhile, when the composite slid against PEEK in seawater, lower friction coefficient of 0.052 and wear rate were obtained. The excellent tribological performance would be attributed to the denser ceramic structure, weakened abrasive wear and tribo-chemical removal.
Comparison On The Immersion Corrosion and Electrochemical Performance of WC-Al2O3 Composites and WC-Co Hard Metal in NaCl Solution

Published: April 2021

Abstract
WC-15wt.%Al2O3 composites was prepared via hot pressing sintering technology. The corrosion behaviors of WC-Al2O3 composites and traditional WC-Co hard alloy in NaCl solution were studied by immersion corrosion and electrochemical technique. The impedance value of WC-Al2O3 composite increased more rapidly than WC-Co hard metal during the 24 hours, which indicated that WC-Al2O3 composites has more compact passivation film than WC-Co hard metal. The results confirmed that the corrosion performance of WC-Al2O3 composites was higher than WC-Co cemented carbide in NaCl solution. The corrosion mechanism of WC-Al2O3 composites and WC-Co hard alloy in NaCl solution were also revealed by SEM, EDS, XPS and Raman. The corrosion products of WC-Al2O3 composites mainly contain WO3, while for WC-Co hard alloy are Co (OH)2, Co3O4 and WO3. The different corrosion mechanism of the two materials is attributed to the Al2O3 phase instead of the Co binder, which avoids the galvanic corrosion between WC phase and Co binder.
Doped Metasurfaces: Optical Metasurfaces without Etched Structure based on Regular Spatially-doped Semiconductor and Compatible with General Functional Optical Films

Published: April 2021

Abstract
As a new-type artificial two-dimensional planar array structure, metasurfaces can achieve the modulation of light field through a reasonable design and arrangement of sub-wavelength nano-structure units, which is expected to surpass conventional optical components theoretically. However, the metal or dielectric metasurfaces fabricated by etching process are often trapped in the problems including low focusing efficiency and difficult preparation, which greatly hinders their practical implementation. Here, an idea of “Doped metasurfaces” based on a spatial and regular doping of semiconductor thin films is proposed for the first time. This kind of metasurfaces without etched structure owns smooth and flat surface, allowing the addition of optical functional films like anti-reflection film, which thus gets their optical properties greatly improved and enriched on the basis of meta-structured focusing characteristics. In order to verify the effectiveness of this strategy, we simulate a doped metalens suitable for wide mid-infrared (MIR) range and design an anti-reflection film on it. It is shown that this designed MIR metalens possesses wide operating range, high transmittance and high focusing efficiency. The method proposed here provides a new idea or perspective for constructing metasurfaces devices compatible with traditional optical thin films.

Abstract
Dramatic evolution of properties with minute change in the doping level is a hallmark of the complex chemistry which governs copper oxide superconductivity as manifested in the celebrated superconducting domes as well as quantum criticality taking place at precise compositions. The strange metal state, where the resistivity varies linearly with temperature, has emerged as a central feature in the normal state of copper oxide superconductors. The ubiquity of this behavior signals an intimate link between the scattering mechanism and superconductivity. However, a clear quantitative picture of the correlation has been lacking. Here, we report the observation of quantitative scaling laws between the superconducting transition temperature Tc and the scattering rate associated with the strange metal state in electron-doped copper oxide La2-xCexCuO4 (LCCO) as a precise function of the doping level (x). High-resolution characterization of epitaxial composition-spread films, which encompass the entire overdoped range of LCCO has allowed us to systematically map its structural and transport properties with unprecedented accuracy and increment of Δx = 0.0015. We have uncovered the relations Tc ~ (xc-x)0.5 ~ (A1)0.5, where xc is the critical doping where superconductivity disappears on the overdoped side and A1 is the scattering rate of perfect T-linear resistivity per CuO2 plane. We argue that the striking similarity of the Tc vs A1 relation among copper oxides, iron-based and organic superconductors is an indication of a common mechanism of the strange metal behavior and unconventional superconductivity in these systems.
Toll/interleukin-1 Receptor Domain-Only Protein of Arabidopsis Thaliana AtTX14 2IR, Produced By Alternative Splicing, Can Induce Defense Responses
Authors: Lim Jaebeom , Yeon Jinouk , Song Sang-Kee , Yi Hankuil 
Published: April 2021

Abstract
Toll/interleukin -1 receptor (TIR) domains, which have NAD+ cleavage activity, are used as signaling modules in NOD-like receptors for defense responses. It has been shown that TIR domains not only form homo- or heterodimers with TIR domain-containing proteins but also interact with various proteins. A previous study showed that overexpression of Arabidopsis thaliana (Arabidopsis) AtTX14, encoding an N-terminal TIR domain and a C-terminal domain with unknown function, resulted in dwarfism and constitutive defense signaling or autoimmunity. Transgenic Arabidopsis overexpressing AtTX14 displays enhanced defense responses and associated dwarf phenotypes at 28 °C compared with those at 22 °C, which differs from other mutant or transgenic Arabidopsis with constitutive defense responses. We found that AtTX14 is alternatively spliced to encode three different proteins, and the TIR domain itself can induce autoimmunity and elevated defense responses to the bacterial pathogen Pseudomonas syringae pv. tomato. In addition, we revealed that the transcription of AtTX14 is regulated by a positive feedback mechanism. With transient overexpression of three AtTX14 protein forms in tobacco leaves, providing a heterologous system free from the positive feedback of AtTX14 in Arabidopsis, we demonstrated that expression of a splicing variant encoding the TIR domain-only protein is sufficient to activate defense signaling. A deeper understanding of interaction networks involving AtTX14 will broaden our knowledge on how plant defense signaling is regulated in response to pathogen infection and ambient temperature changes.

Published: April 2021

Abstract
Background: This study aimed to evaluate factors related to the fear of cancer recurrence (FCR) in stomach cancer survivors.Methods: A total of 363 stomach cancer survivors were divided into three groups according to the Korean version of the FCR Index (FCRI). We compared the socio-demographic and cancer-related factors, communication within the medical team during treatment, care coordination, social support, physical symptoms, psychological distress, and health-related quality of life (HRQoL), and health promotion and disease prevention activity, which was defined as second primary cancer screening, osteoporosis evaluation, supplementary drug intake, dietary pattern, regular exercise, and smoking cessation, according to the levels of FCRI using the linear regression analysis after adjusting for age, sex, stage, time since diagnosis, family cancer diagnosis, and comorbidities.Results: An average of 7.3 years have passed since diagnosis. The highest FCRI group was younger or had a high percentage of family cancer diagnosis. Satisfaction for communication and care coordination, social support, HRQoL, and physical symptoms, such as fatigue, pain, and insomnia, were negatively associated with the FCR of stomach cancer survivors. Anxiety and depression were positively associated with the FCR. However, FCR was not associated with sex, time since diagnosis, cancer stage, treatment modality, socioeconomic status, or health promotion and disease prevention activity.Conclusions: FCR in stomach cancer survivors was associated with physical, psychological, and HRQoL factors rather than socio-demographic or cancer–related factors. Understanding the association between HRQoL, physical and psychosocial factors, and FCR may advance survivorship care for stomach cancer survivors.

Published: April 2021

Abstract
Objectives: Merecidin induced A549 cells apoptosis. The present study aimed to assess the differentially phosphorylated proteins in lung cancer A549 cells treated with antibacterial peptide merecidin. Methods: TMT/iTRAQ labeling, LC-MS/MS analysis, HPLC grading, IMAC modification and enrichment, and liquid chromatography-mass spectrometry of peptide. The data of proteins were filtered according to the localization probability >0.75 standard. The phosphorylated proteomics data were analyzed using GO, KEGG, and STRING databases. Western blots examined the changes in phosphorylated protein expression. Results: Protein function enrichment showed significant changes in the phosphorylation level with respect to protein binding, metabolic activity, molecular function regulation, cell process, and biological function regulation. Integrated pathway bioinformatics results showed that differential proteins are associated with several pathways, including mTOR and AMPK etc. Screening of the COG database revealed differentiated phosphorylated proteins in cell signal transduction, RNA transcription, translation processing and modification, ribosome synthesis of proteins, cytoskeleton protein formation, intracellular material transport, secretion, and vesicle transport. Protein interaction level analysis identified an interaction network with HDAC1, RPL23A, SRSF3H, and NCBP1.etc. The phosphorylated proteomics data and showed that after merecidin treatment, ATG2B and ULK1s were significantly upregulated, while MAPK1 and AKT were significantly downregulated. In addition, Western blot also showed the upregulated level of ATG13,ULK1;MAPK1 downregulated. Conclusion: The results verified the feasibility of phosphorylated proteomics analysis, confirmed the signaling pathways, and suggested that merecidin may induce autophagy of lung adenocarcinoma A549 cells.
Natural History and Prognostic Implications of Left Ventricular End-Diastolic Pressure in Reperfused ST-Segment Elevation Myocardial Infarction – An Analysis of the Thrombolysis in Myocardial Infarction (TIMI) II Randomized Controlled Trial.
Authors: Khan Arshad A , Al-Omary Mohammed S , Collins Nicholas J , Attia John , Boyle Andrew 
Published: April 2021

Abstract
Background

The aim of the current study is to assess the natural history and prognostic value of elevated left ventricular end-diastolic pressure (LVEDP) in patients with ST-segment elevation myocardial infarction (STEMI) after reperfusion with thrombolysis; we utilize data from the Thrombolysis in Myocardial Infarction II study.
Methods

A total of 3,339 patients were randomized to either an invasive (n = 1,681) or a conservative (n = 1,658) strategy in the TIMI II study following thrombolysis. To make the current cohort as relevant as possible to modern pharmaco-invasively managed cohorts, patients in the invasive arm with TIMI flow grade ≥ 2 (N = 1201) at initial catheterization are included in the analysis. Of these, 259 patients had a second catheterization prior to hospital discharge, and these were used to define the natural history of LVEDP in reperfused STEMI.
Results

The median LVEDP for the whole cohort was 18 mmHg (IQR: 12–23). Patients were divided into quartiles by LVEDP measured during the first cardiac catheterization. During a median follow up of 3 (IQR: 2.1–3.2) years, quartile 4 (highest LVEDP) had the highest incidence of mortality and heart failure admissions. In the cohort with paired catheterization data, the LVEDP dropped slightly from 18 mmHg (1QR: 12–22) to 15 mmHg (IQR: 10–20) [p = 0.01] from the first to the pre-hospital discharge catheterization.
Conclusions

LVEDP remains largely stable during hospitalisation post-STEMI. Elevated LVEDP is a predictor of death and heart failure hospitalization in STEMI patients undergoing successful thrombolysis.

Published: April 2021

Abstract
Background Covid-19 pneumonia is the leading cause of death in severe hospitalized patients. Thalidomide has an immunomodulatory and anti-inflammatory effect and thereby decrease lung damage.Methods This study was a randomized clinical trial that was performed from April 2020 until August 2020 on 60 severe hospitalized Covid-19 pneumonia patients. All patients received the usual care for Covid-19 pneumonia based on our hospital protocols. Patients in the intervention group received thalidomide tablets 100 mg daily for 14 days added to the usual treatment. The primary outcome was the ICU admission rate.Results Thirty patients were assigned to receive thalidomide and 30 patients usual treatment. Five patients (17.9%) in the thalidomide group required ICU admission and 12 patients (52.2%) in the usual care group (P-value = 0.01). ICU admission hazard ratio was 3.3 higher in the usual care group than the thalidomide group (HR: 3.31 [95% CI: 1.16–9.45]). Hospitalization duration, intubation and mortality showed no significant differences between the two groups (P > 0.05 for all items). No serious and major adverse effects were reported during the trial.Conclusion The use of thalidomide was associated with a decreased rate of ICU admission in severe hospitalized covid-19 patients.
Premature deindustrialization and development without factories. Are services sectors a new path for the development of sub-Saharan African countries?
Authors: Chenaf-Nicet Dalila , Asse Betty 
Published: April 2021

Abstract
For some authors (Rodrik, 2015 and 2017) deindustrialization process is premature in sub-Saharan countries. This means that the period of industrialization has been too short, with too little job creation and growth to guarantee a development trajectory. For these authors, the consequences for development are necessarily negative. However, in this work, the economic causes are: the global demand for services is growing faster than the demand for manufactured goods. This growth would leave too few development opportunities for industries in these countries that suffer from narrow domestic markets. Global demand for services and weak domestic demand are the causes of this deindustrialization. However, according to other authors (Loungani et al. 2017), if sub-Saharan African countries (SSA) deindustrialize, they should still be able to benefit from development opportunities through the services sector, which will be a new development path without factories (Ghani and O’Connel, 2014; Dihel and Grover, 2016). This article is part of the controversy. It tests the impacts of different sectors on growth, for a sample of 57 developing countries (Asia, SSA, and Latin America) in a panel data model over the period from 1984 to 2017. Our work shows that the services sector generates few spill-over effects on the income of SSA, which remains highly specialized in low-knowledge-intensive services.

Published: April 2021

Abstract
Objectives: Little is known about both Asian and Asian American (A/AA) and non-Asian young adults’ experiences and emotional reactions regarding COVID-19 anti-Asian discrimination. This is the first study to explore the nature and impact of COVID-19 anti-Asian discrimination through a racially diverse sample. Design: This study uses open-ended qualitative free-text responses from Wave I of the COVID-19 Adult Resilience Experiences Study (CARES) data collected between March to September 2020. Thematic analysis was used to explore two open-ended questions: “Are there experiences we missed in the survey so far that you wish to describe?” and “What are your thoughts about the current social climate?” The data analysis for this study focused on 113 discrimination or racism-related comments. Results: A total of 1,331 young adults completed an online survey of which 611 provided comments; a total of 95 racially diverse individuals (65.3% non-Asians) contributed 113 COVID-19 anti-Asian discrimination or racism-related comments. Two overarching themes were: types of discrimination (societal, interpersonal, intrapersonal), and emotional reactions to discrimination (fear, anxiety/distress, hopeless/depression, and avoidance). Not only did both A/AA and non-Asian participants report witnessing or hearing reports of anti-Asian discrimination, but both groups reported experiencing negative emotional reactions to anti-Asian discrimination. Conclusion: Anti-Asian discrimination in the face of COVID may be more widespread than initial reports indicate. Our finding suggests that anti-Asian discrimination is a societal illness that impacts all populations in the U.S. This calls for cross-racial coalitions and solidarity in the fight against discrimination and racism.
Exploring the Impact of Enterprise Social Media Affordances on Work Performance and Knowledge Transfer

Published: April 2021

Abstract
Knowledge is the result of collective work. As an important component of human capital and intangible assets of the company, when properly processed, knowledge transfer can foster work performance. For a decade, enterprise social media affordances have been studied based on surveys of different platforms users, not allowing to submit the users to the same conditions, therefore, ignoring the effects of platform design on enterprise social media. To address this gap, this empirical research studies the effect of enterprise social media affordances on employee performance from the perspective of knowledge transfer, using a single platform. The analysis of survey data collected from 317 Malagasy employees using the company’s own intranet has shown that association, visibility, persistence and editability affordances of ESM foster knowledge acquisition and knowledge provision, which in turn promote employee performance. Findings show that the relationship between ESM affordances and work performance are essentially mediated by knowledge provision. This study provides the key variables for a sustainable performance of the co-creation of value in the knowledge transfer process of the technological innovation process, and the levers for action on these variables. These variables are identified from the intersection of the technological (ESM affordances), social (knowledge provision and knowledge acquisition) and organizational (task performance and contextual performance) dimensions of the knowledge transfer process.
Dementia Management Act and Death Toll by Dementia Drug
Authors: Lee Jong-hoon 
Published: April 2021

Abstract
The Dementia Management Act (DMA) came into effect on August 04 2011, South Korea. Medical data on the correlation between Alzheimer's disease (AD) and anti-AD drugs (AAD) groups were observed from 2010 to 2019. This study investigated the increase and decrease of deaths and AAD used to treat AD. It is known that psychotropic medicines should not be administered for dementia patients because they increase all-cause mortality. This study demonstrated that acetylcholinesterase inhibitors also increase the death toll when used to treat dementia.
Team Science in Precision Medicine: Study of Coleadership and Coauthorship Across Health Organizations
Authors: An Ning , Mattison John , Chen Xinyu , Alterovitz Gil 
Published: April 2021

Background
Interdisciplinary collaborations bring lots of benefits to researchers in multiple areas, including precision medicine.

Objective
This viewpoint aims at studying how cross-institution team science would affect the development of precision medicine.

Methods
Publications of organizations on the eHealth Catalogue of Activities were collected in 2015 and 2017. The significance of the correlation between coleadership and coauthorship among different organizations was calculated using the Pearson chi-square test of independence. Other nonparametric tests examined whether organizations with coleaders publish more and better papers than organizations without coleaders.

Results
A total of 374 publications from 69 organizations were analyzed in 2015, and 7064 papers from 87 organizations were analyzed in 2017. Organizations with coleadership published more papers (P<.001, 2015 and 2017), which received higher citations (Z=–13.547, P<.001, 2017), compared to those without coleadership. Organizations with coleaders tended to publish papers together (P<.001, 2015 and 2017).

Conclusions
Our findings suggest that organizations in the field of precision medicine could greatly benefit from institutional-level team science. As a result, stronger collaboration is recommended.
