The complexity of invasion process of alien species is very high and requires better understanding. Nowadays, the successful range expansion of Erechtites hieraciifolia is being observed in Poland. In the study, the distribution of the species in Poland was summarized, based on the available literature and new field data. The fieldworks were conducted in the part of the species expansion zone located in central and north-eastern Poland. Two case studies on species encroachment into post-fire and transitional bog communities were performed and a case inventory of the species presence on the border of its main secondary range was conducted. The measurements of height, counting of the number of inflorescences per individual and the number of achenes per flower head were conducted in selected stands. There was performed a checking of local conditions of growth using ecological indicator values for vascular plants. The analyzed specimens of the species had significantly less inflorescences and achenes than in the other parts of the species expansion zone. They grew also in worse light conditions and in less fertile sites. The species colonized most disturbed patches at first. It spread to the less disturbed ones and omitted natural sites. The massive colonization of the transitional bog could be caused by groundwater level lowering. In the area of the edge of the species main range it was found in many diffuse stands within disturbed patches of the landscape. Based on the obtained results the species is considered to create now still only a moderate threat in the analyzed part of the expansion zone. The possibility of its expansion to wetland sites and sudden appearance in Kampinos National Park needs much more attention.

Women and War in Rwanda
Authors: Holmes Georgina 
Published: May 2020

The 1994 genocide in Rwanda, which followed the death of President Habyarimana, was one of the worst humanitarian disasters of the twentieth century and shamed both African and global leaderships. As wars in the Congo continue to tear apart the region, this book examines how the politics that led to the 1994 genocide continue to be played out in the international media. Scholars of political science contend that narratives are used strategically by states to influence and shape the behaviour of other actors in the international system. This book explore how, through processes of denial and revisionism, strong states with geopolitical interests in the Great Lakes region of Africa, African states directly involved in conflict, militia groups and rebels, as well as human rights activists and NGOs, all employ media narratives strategically with the aim of influencing political decision-making and public perceptions of genocide and war.Examining how international political discourse on the 1994 genocide in Rwanda is gendered, Georgina Holmes argues that states, militaries and human rights organisations use gendered narratives for political gain, and breaks new ground in analysing the role of gender in the conflict.
This book is essential reading on the gendered dynamics of conflict and genocide in Rwanda and the Democratic Republic of Congo and will appeal to anyone with an interest in Gender Studies, Political Communication, Media and Film Studies, African Studies, Genocide Studies and International Relations.
Lacan Reframed
Authors: Levine Steven Z 
Published: May 2020

Are your students baffled by Baudrillard? Dazed by Deleuze? Confused by Kristeva? Other beginners' guides can feel as impenetrable as the original texts to students who 'think in images'. "Contemporary Thinkers Reframed" instead uses the language of the arts to explore the usefulness in practice of complex ideas. Short, contemporary and accessible, these lively books utilise actual examples of artworks, films, television shows, works of architecture, fashion and even computer games to explain and explore the work of the most commonly taught thinkers. Conceived specifically for the visually minded, the series will prove invaluable to students right across the visual arts. Single-handedly responsible for the influential and ominous notion of 'the gaze', quoted by everybody yet fully understood by few, Lacan's work can be difficult to grasp. Going back to basics, this introduction guides the reader through Lacan's key concepts by looking at art from the Mona Lisa through to Bridget Riley's paintings, and by looking afresh at key works discussed by Lacan himself, from Holbein's famous 'The Ambassadors' to Velazquez's 'Las Meninas'.
Making sense of Lacan's sometimes convoluted style, this highly readable introduction to one of the most frequently quoted thinkers also explores the reasons why human beings make - and look at - art.

Life Insurance Corporation of India, the capital intensive business, provides the most important financial instrument to customers aimed at protection as well as long term savings. The Corporation reaches out to the people through the main traditional route of the agency model for the selling processes of the numerous complex need-based products. The agents help in marketing its policies by spreading the message of life insurance among the masses. They serve as the kingpin for insurance companies seeking to provide traditional and innovative products, and focal point for customers seeking to procure insurance coverage and long term savings. The present paper investigates the factors influencing agents’ perception towards Life Insurance Corporation of India. The study is based on a sample of 225 respondents taken from three cities of Punjab. Factor Analytic Approach has been performed for data analysis. The results of the factor analysis reveal that Staff co-ordination is the most important factor to influence agents’ perception followed by other six factors namely: (i) Customer target; (ii) Competitive advantage predicates; (iii) Material hallmarks; (iv) Promising products and process; (v) Service enhancement; and (vi) Exclusive attention. Moreover, analysis of one way classification has also been performed to test the significant differences among the various groups of respondents across the 23-item perception scale.

María en altares de Oshun: pedidos y ex-votos en contextos de hibridación cultural (Zárate y Campana)
Authors: Fogelman Patricia Alejandra 
Published: May 2020

Analizaré los altares dedicados a Oshun, orishá del Batuque, en Zárate y Campana (Provincia de Buenos Aires, Argentina), enfocando sobre aquellos que incluyen representaciones de la Virgen María. El culto mariano tiende a expandirse en América Latina a través de numerosas vías. Es llamativa la presencia de sus imágenes mezcladas o reapropiadas por la religiosidad de matriz africana provenientes del Brasil. Porosidad en creencias y prácticas, presencia de desplazamientos e hibridaciones entre las ofrendas en los altares serán investigadas en su doble perfil: de fuentes visuales pasibles de indagación histórica (atendiendo a las funciones de la imagen) y en lo que hace a su calidad de exvotos de reconocimiento por gracias hipotéticamente recibidas. Espero contribuir al área de los estudios culturales de la religión contemporánea desde un enfoque histórico sobre el Batuque en relación con la dinámica del culto mariano. Las imágenes (fotografías de altares) serán las principales fuentes.

Anticomunismo e Inimigo Interno: uma avaliação da Doutrina de Segurança Nacional a partir de sujeitos e manuais da repressão durante as ditaduras do Conesul
Authors: Vinicius Ribeiro Marcos 
Published: May 2020

O artigo parte de uma análise teórica-conceitual da historiografia que debate os usos do passado para produzir síntese crítica a respeito das rupturas e permanências de alguns aspectos da construção e adaptação da Doutrina de Segurança Nacional (DSN) para a América Latina, a partir de manuais militares redigidos por interlocutores da repressão (civis e militares) em documentos anticomunistas. Procuramos demonstrar em manuais da repressão e documentos da Confederação Anticomunista Latino-americana (CAL), como a construção do “inimigo interno”, produzida durante o período de vigência da política de Terrorismo de Estado (TDE) que caracterizou as Ditaduras de Segurança Nacional, foi articulado e acionado como fórmula de combate e perseguição às oposições durante as ditaduras. Finalizamos o artigo com uma avaliação de conjunto que situa algumas permanências do anticomunismo como elemento orgânico de disputa da hegemonia.
SEM CORPO OU SEM CABEÇA, O CORPO DE LA MUJER DESNUDA DE ARMONÍA SOMERS
Authors: Carlos de Andrade Brenda 
Published: May 2020

Neste trabalho, analisa-se a obra La mujer desnuda, de Armonía Somers focando na maneira como a autora uruguaia constrói um recentramento do corpo feminino, que, desviando da norma, toma sua liberdade em busca da realização de seus desejos. A análise se dá na forma como a protagonista se relaciona com esse caminho de autodescoberta e também como ela e seu corpo são percebidos pelos outros personagens. As interações geradas por um evento fantástico que reinscreve o corpo feminino a partir de uma trama aparentemente simples de encontros entre personagens permitem entrever práticas de violência e de desejos frustrados que figuram como parte da realidade cotidiana das mulheres.

Published: May 2020

Background
Gastric cancer is one of the most common malignant cancers worldwide. Despite substantial developments in therapeutic strategies, the five-year survival rate remains low. Therefore, novel biomarkers and therapeutic targets involved in the progression of gastric tumors need to be identified.

Methods
We obtained the mRNA microarray datasets GSE65801, GSE54129 and GSE79973 from the Gene Expression Omnibus database to acquire differentially expressed genes (DEGs). We used the Database for Annotation, Visualization, and Integrated Discovery (DAVID) to analyze DEG pathways and functions, and the Search Tool for the Retrieval of Interacting Genes (STRING) and Cytoscape to obtain the protein–protein interaction (PPI) network. Next, we validated the hub gene expression levels using the Oncomine database and Gene Expression Profiling Interactive Analysis (GEPIA), and conducted stage expression and survival analysis.

Results
From the three microarray datasets, we identified nine major hub genes: COL1A1, COL1A2, COL3A1, COL5A2, COL4A1, FN1, COL5A1, COL4A2, and COL6A3.

Conclusion
Our study identified COL1A1 and COL1A2 as potential gastric cancer prognostic biomarkers.

Published: May 2020

AbstractBuckled elemental analogs of graphene—2D‐Xenes silicene, germanene, and stanene—and their derivatives are predicted to host high‐mobility carriers. Experiments, however, have not as yet confirmed the predictions. Here, high‐mobility (exceeding 104 cm2 V−1 s−1) carriers are discovered in intercalated multilayer germanene. Epitaxial films of antiferromagnetic and diamagnetic MGe2 are synthesized via topochemical reactions, followed by extensive studies of the atomic and magnetic structures. Quantum oscillations in MGe2 resistance manifest quasi‐2D Fermi‐surface pockets with effective masses of carriers as low as 0.015 me, comparable to graphene. The detected signature of the chiral anomaly in magnetoresistance and nonzero Berry phases may indicate the topological nature of the MGe2 electronic structure and charge transport. The discovery bridges the gap between theory and experiment, thus establishing 2D‐Xenes as promising building blocks in materials engineering. Concurrently, the combination of magnetism and high mobility in Eu‐intercalated germanene is attractive for spintronic applications.

AbstractDesigning high‐activity catalysts and revealing the in‐depth structure–property relationship is particularly important for Li–O2 batteries. Herein, the self‐boosting catalysis of LiCoO2 as an electrocatalyst for Li–O2 batteries and the investigation of its self‐adjustment mechanism using in situ X‐ray absorption spectroscopy and other operando characterization techniques is reported. The intercalation/extraction of Li+ in LiCoO2 not only induces the change in Co valence and modulates the electronic/crystal structure but also tunes the surface disorder degree, lattice strain, and local symmetry, which all affect the catalysis activity. In a discharge, highly ordered LiCoO2 acts as a catalyst to boost oxygen reduction reaction. During charging, the initial extraction of Li+ from LiCoO2 induces Li/oxygen vacancy and Co4+, which deforms CoO6 octahedron as well as lowers the symmetry, and accordingly promotes oxygen evolution reaction. This article offers insights into tuning the activity of catalysts for Li–O2 batteries with the intercalation/extraction of alkali metal ions in traditional cathodes.

Published: May 2020

AbstractChronic bone infection is considered as one of the most problematic biofilm‐related infections. Its recurrent and resistant nature, high morbidity, prolonged hospitalization, and costly medical care expenses have driven the efforts of the scientific community to develop new therapies to improve the standards used today. There is great debate on the management of this kind of infection in order to establish consistent and agreed guidelines in national health systems. The scientific research is oriented toward the design of anti‐infective biomaterials both for prevention and cure. The properties of these materials must be adapted to achieve better anti‐infective performance and good compatibility, which allow a good integration of the implant with the surrounding tissue. The objective of this review is to study in‐depth the antibacterial biomaterials and the strategies underlying them. In this sense, this manuscript focuses on antimicrobial coatings, including the new technological advances on surface modification; scaffolding design including multifunctional scaffolds with both antimicrobial and bone regeneration properties; and nanocarriers based on mesoporous silica nanoparticles with advanced properties (targeting and stimuli‐response capabilities).

AbstractThe capability of manipulating the interfacial electronic coupling is the key to achieving on‐demand functionalities of catalysts. Herein, it is demonstrated that the electronic coupling of Fe2N can be effectively regulated for hydrogen evolution reaction (HER) catalysis by vacancy‐mediated orbital steering. Ex situ refined structural analysis reveals that the electronic and coordination states of Fe2N can be well manipulated by nitrogen vacancies, which impressively exhibit strong correlation with the catalytic activities. Theoretical studies further indicate that the nitrogen vacancy can uniquely steer the orbital orientation of the active sites to tailor the electronic coupling and thus benefit the surface adsorption capability. This work sheds light on the understanding of the catalytic mechanism in real systems and could contribute to revolutionizing the current catalyst design for HER and beyond.

Published: May 2020

AbstractSequential deposition is certified as an effective technology to obtain high‐performance perovskite solar cells (PVSCs), which can be derivatized into large‐scale industrial production. However, dense lead iodide (PbI2) causes incomplete reaction and unsatisfactory solution utilization of perovskite in planar PVSCs without mesoporous titanium dioxide as a support. Here, a novel autonomously longitudinal scaffold constructed by the interspersion of in situ self‐polymerized methyl methacrylate (sMMA) in PbI2 is introduced to fabricate efficient PVSCs with excellent flexural endurance and environmental adaptability. By this strategy perovskite solution can be confined within an organic scaffold with vertical crystal growth promoted, effectively inhibiting exciton accumulation and recombination at grain boundaries. Additionally, sMMA cross‐linked perovskite network can release mechanical stress and occupy the main channels for ion migration and water/oxygen permeation to significantly improve operational stability, which opens up a new strategy for the commercial development of large‐area PVSCs in flexible electronics.

AbstractOne of the main bottleneck issues for room‐temperature antiferromagnetic spintronic devices is the small signal read‐out owing to the limited anisotropic magnetoresistance in antiferromagnets. However, this could be overcome by either utilizing the Berry‐curvature‐induced anomalous Hall resistance in noncollinear antiferromagnets or establishing tunnel‐junction devices based on effective manipulation of antiferromagnetic spins. In this work, the giant piezoelectric strain modulation of the spin structure and the anomalous Hall resistance in a noncollinear antiferromagnetic metal—D019 hexagonal Mn3Ga—is demonstrated. Furthermore, tunnel‐junction devices are built with a diameter of 200 nm to amplify the maximum tunneling resistance ratio to more than 10% at room‐temperature, which thus implies significant potential of noncollinear antiferromagnets for large signal‐output and high‐density antiferromagnetic spintronic device applications.

AbstractTissue interfaced electronics have become promising candidates for transcending beyond conventional diagnostic technology, enabling chronic, quantitative health monitoring possibilities; however, these systems have primarily relied on impenetrable materials that contribute to the mechanical and physical mismatch of bioelectronic interfaces. Inspired by the soft mechanics and physical architecture of the epidermal extracellular matrix, this study presents a 3D microporous, fibrous mesh of polydimethylsiloxane for epidermal electronics. The resulting elastic microfiber mat, exhibits a minimal mechanical footprint with analogous viscoelastic behavior, cytocompatibility, and biofluid‐permeable interface capable of small molecule, gas, and transdermal water diffusion. Electrocardiography electrodes heterogeneously integrate within the synthetic electronic‐extracellular matrix (e‐ECM) membrane and achieve chronic high resolution biopotential monitoring during typically debilitating environments (e.g., vigorous sweating) for conventional bioelectronics. The e‐ECM platform provides a substrate template for open‐mesh electronics, enabling advanced implementations in long‐term quantitative analysis monitoring for wearable and implantable devices.

Published: May 2020

AbstractRadar and sonar technologies are generally used to detect objects in air space and water. In some cases, both technologies are involved in probing waterborne objects like submarines. However, the simultaneous stealth regarding these two detection methods is not well explored due to the difficulty in satisfying material properties for two different physical systems. In this work, an artificial ultrathin amphibious stealth coat with a minimum thickness less than 0.5 mm achieving free‐space microwave and underwater acoustic absorption is proposed and demonstrated. It is realized by combining an electromagnetic metasurface and an acoustic metasurface—a flexible printed circuit with multisized metal resonators and a polydimethylsiloxane film with multisized air cavities. These two alien metasurfaces are engineered with minimized disturbance to each other by controlling the thicknesses of the resonators as thin as possible. A free‐space microwave absorptivity over 80% in the 12.38–13.7 GHz region and an underwater acoustic reflectance less than 10% in the 80–160 kHz region are obtained experimentally. The current work may shed light on advanced stealth technologies of the free‐space microwaves and underwater acoustic waves.
