Macroscale carbon nanotube layers, also known as buckypapers (BP), were produced and inserted between glass fiber/epoxyprepregs to evaluate the electromagnetic interference shielding effectiveness (EMI SE) in the X band range. The numberof BP layers (S) and the wave-transmitting layer thickness (d) diverged so that five sandwich configurations were proposedin this work. The optimized architecture (S = 4 and d = 1.0 mm) led to a high shielding performance, revealing an EMI SEup to ~ 60 dB with a dominant absorption mechanism and an imposing Fabry-Pérot resonance peak. The fabrication of BPcomposites is uncomplicated and highly straightforward for large-scale manufacturing of promising EMI shielding materialswith broad applications in electronics.

Background: Despite the advances in glioblastoma (GBM) treatment, the average life span of patients is 14 months. Therefore, it is urgent to identity biomarkers of prognosis, treatment response, or development of novel treatment strategies. We previously described the association of high epidermal growth factor-like domain multiple 7 (EGFL7) expression and unfavorable outcome of pilocytic astrocytoma patients. The present study aims to analyze the prognostic potential of EGFL7 in GBM isocitrate dehydrogenase (IDH)-wildtype, using immunohistochemistry and in silico approaches.Methods: Spearman’s correlation analysis of The Cancer Genome Atlas RNA sequencing data was performed. The genes strongly correlated to EGFL7 expression were submitted to enrichment gene ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. Additionally, EGFL7 expression was associated with patient overall survival. The expression of EGFL7 was analyzed through immunohistochemistry in 74 GBM IDH-wildtype patients’ samples, and was associated with clinicopathological data and overall survival.Results: In silico analysis found 78 genes strongly correlated to EGFL7 expression. These genes were enriched in 40 biological processes and eight KEGG pathways, including angiogenesis/vasculogenesis, cell adhesion, and phosphoinositide 3-kinase–Akt, Notch, and Rap1 signaling pathways. The immunostaining showed high EGFL7 expression in 39 cases (52.7%). High immunolabelling was significantly associated with low Karnofsky Performance Status and poor overall survival. Cox analysis showed that GBMs IDH-wildtype with high EGFL7 expression presented a higher risk of death compared to low expression (hazard ratio, 1.645; 95% confidence interval, 1.021 to 2.650; p = .041).Conclusions: This study gives insights regarding the genes that are correlated with EGFL7, as well as biological processes and signaling pathways, which should be further investigated in order to elucidate their role in glioblastoma biology.
LUXURY BRANDS SOCIAL MEDIA MARKETING EFFORTS: INFLUENCE ON BRAND EQUITY AND CONSUMERS’ BEHAVIOR

There is relatively little evidence on how social media marketing activities influence brand equity creation and consumers’ behavior towards the brand. We explore these relationships by analyzing pioneering brands in the luxury sector (Burberry, Dior, Gucci, Hermès, and Louis Vuitton). Based on a survey of 845 luxury brand consumers (Chinese, French, Indian and Italian) who follow the five brands studied on social media, we developed a structural equation model that helps to address gaps in prior social media branding literature. Specifically, our study demonstrates the links between social media marketing efforts – measured as a holistic concept incorporating five aspects (entertainment, interaction, trendiness, customization and word of mouth) and their consequences (brand preference, price premium and loyalty).

The Eurasian Economic Union is an institution formalized in January 2015 for the purpose of regional economic integration; it includes five countries: Russia, Kazakhstan, Belarus, Armenia, and Kyrgyzstan, and may include Mongolia and Tajikistan in the future. With a GDP of $1.59 trillion in 2015, an industrial production of $1.3 trillion in 2014, and population of almost 200 million as of 2016, the EEAU could represent a geopolitical success that supports both Putin's ambitious political agenda and the Union's economic prospects. Although the efforts of this Union are ongoing and long-term success is not certain, the Russia-led Eurasian Economic Union can be considered a hybrid half-economics and half-political “Janus Bifrons” that serves as a powerful illustration of what Putin envisions for the post-Soviet space. Despite promising steps so far, more should be done toward the achievement of economic development and balanced opportunity for all Eurasian countries. Russia's longstanding role within the Union, as well as its power and political motivations, are all considerations that must be accounted for.
