Physical Space and Mental Barriers in Russian Emigrants’ Experience ("The Mushroom Picker" by Zinovyi Zynyck)
Taking into account the novel "The Mushroom Picker" there are a lot of kinds of the word “frontier”. Their meaning depends on a question: what we would like to express using them. Not only does the Russian author write about space borders between countries but he considers mental barriers as well. In his opinion, the latter ones are drastically more dangerous because they often lead to arguments and even wars between nations which have no knowledge and understanding of different cultures. The main character of the novel shows the reader both Soviet and English reality. The capital cities of these countries – Moscow and London – are presented critically. The citizens of both countries do not trust each other, and do not even try to know anything about different conditions in which they live. The protagonists are proud only of their own culture and history, and do not respect other nations. There are not any spiritual values, friendship and agreement among people. In this way "The Mushroom Picker" turned to be very pessimistic.

A Evolução da Imprensa sobre Cinema em Portugal
Authors: Lourenço Jaime , Centeno Maria João 
Published: October 2019

A investigação sobre Jornalismo de Cinema (aqui entendido como um subgénero do Jornalismo Cultural) é praticamente inexistente em Portugal e sendo o cinema uma das manifestações artísticas com maior presença na imprensa portuguesa (de acordo com os dados do projecto de investigação A Cultura na Primeira Página[Baptista, 2014; 2017a; 2017b]), importa aprofundar a investigação sobre este subgénero do Jornalismo Cultural.
Neste sentido, e numa perspectiva histórica, a relação entre o cinema e o jornalismo é quase tão antiga como a própria sétima arte. De acordo com Barroso (2008: p. 23), "desde os primórdios do cinema que se começa gradualmente a impor uma cultura cinematográfica impossível de conceber sem a existência de textos que falam dos filmes e leitores interessados nas fitas". Em Portugal, a primeira publicação dedicada em exclusivo ao cinema surge na década de 1910 e, a partir daí, proliferam as publicações sobre cinema que têm acompanhado a implementação do cinema na vida dos portugueses e a edificação do cinema português. É a partir da segunda metade do séc. XX que se começa a constatar “uma aceleração do gosto cinematográfico” (Barroso, 2008:26) e uma consolidação das publicações sobre cinema em Portugal.
Neste artigo, focamos o nosso olhar nas décadas de 1950 a 1980 e, através da revisão de literatura e análise de conteúdo às principais publicações sobre cinema, procuramos traçar a evolução da imprensa sobre cinema em Portugal atendendo à história do cinema português e ao contexto em que essas publicações surgiram e circularam.
Percutaneous Coronary Intervention for Interposed Coronary Graft Stenosis after Modified Bentall Procedure in a Teenaged Boy with Takayasu Arteritis
Authors: Ikenaga Hiroki , Kurisu Satoshi , Kihara Yasuki 
Published: October 2019

Anastomotic occlusion of an interposed coronary artery graft after a Bentall procedure is rare and catastrophic. It can lead to myocardial infarction or sudden cardiac death. We found several reports of occlusion and stenosis of a coronary-graft anastomosis, but few describe occlusion of the interposed coronary graft itself, as evaluated with use of intracoronary ultrasonography and computed tomography.
We report the case of a 17-year-old boy with Takayasu arteritis who had a myocardial infarction caused by severe ostial stenosis in an interposed left coronary graft. The graft occlusion was confirmed by results of electrocardiography, aortography, and intracoronary ultrasonography. The patient was treated with percutaneous coronary intervention, stenting of the interposed graft, and thrombectomy, but he died of left ventricular dysfunction caused by extensive myocardial infarction. Extrinsic compression may have caused the graft occlusion.
When considering emergency percutaneous coronary intervention to interposed coronary artery grafts, operators need to identify the cause of occlusion and decide on the best approach for each patient. Stenting the graft may provide temporary relief. During a hemodynamic crisis, immediately reperfusing the graft is crucial.
EndoAnchors Minimize Endoleaks in Chimney-Graft Endovascular Repair of Juxtarenal Abdominal Aortic Aneurysms
Authors: Galiñanes Edgar Luis , Hernandez-Vila Eduardo A. , Krajcer Zvonimir 
Published: October 2019

Juxtarenal abdominal aortic aneurysms (AAAs) are difficult to treat because they often have little or no proximal aortic neck. Patients with this complex anatomy are not usually candidates for an endovascular aneurysm repair (EVAR). Chimney-graft EVAR has been introduced, but type Ia endoleak is a typical risk. We have begun using EndoAnchors to determine whether this risk can be reduced.
From July 2013 through July 2014, we used the chimney-graft EVAR technique in 5 patients whose juxtarenal AAAs had a short or no proximal aortic neck. During the procedure, we implanted EndoAnchors as needed. Postprocedurally, at 30 days, and through end of follow-up (duration, 11–18 mo), all patients had patent endografts without type Ia endoleak (our primary endpoint), visceral stent-graft thrombosis, or renal complications. One patient who received 4 chimney grafts had a postprocedural type II endoleak, which was treated with embolization.
We found it feasible to use EndoAnchors with the chimney-graft technique to prevent type Ia endoleaks in the treatment of juxtarenal AAAs. Further studies are needed to validate this adjunctive technique and to determine its durability.
Face2Face: Real-time facial reenactment
Authors: Thies Justus 
Published: October 2019

Abstract
This article summarizes the dissertation “Face2Face: Realtime Facial Reenactment” by Justus Thies (Eurographics Graphics Dissertation Online, 2017). It shows advances in the field of 3D reconstruction of human faces using commodity hardware. Besides the reconstruction of the facial geometry and texture, real-time face tracking is demonstrated. The developed algorithms are based on the principle of analysis-by-synthesis. To apply this principle, a mathematical model that represents a face virtually is defined. Utilizing this model to synthesize facial imagery, the model parameters are adjusted, such that the synthesized image fits the input image as good as possible. Thus, in reverse, this process transfers the input image to a virtual representation of the face. The achieved quality allows many new applications that require a good reconstruction of the face. One of these applications is the so-called “Facial Reenactment”. Our developed methods show that such an application does not need any special hardware. The generated results are nearly photo-realistic videos that show the transfer of the expressions of one person to another person. These techniques can for example be used to bring movie dubbing to a new level. Instead of adapting the audio to the video, which might also include changes of the text, the video can be post-processed to match the mouth movements of the dubber. Since the approaches that are shown in the dissertation run in real-time, one can also think of a live dubber in a video teleconferencing system that simultaneously translates the speech of a person to another language.
The published videos of the projects in this dissertation led to a broad discussion in the media. On the one hand this is due to the fact that our methods are designed such that they run in real-time and on the other hand that we reduced the hardware requirements to a minimum while improving the resulting quality. In fact, after some preprocessing, we are able to edit ordinary videos from the Internet in real-time. Amongst others, we impose a different mimic to faces of prominent persons like former presidents of the United States of America. This led inevitably to a discussion about trustworthiness of video material, especially from unknown source. Most people did not expect that such manipulations are possible, neglecting existing methods that are already able to edit videos (e. g. special effects in movie productions). Thus, besides the advances in real-time face tracking, our projects raised the awareness of video manipulation.

Dynamical magnetoelectric phenomena of skyrmions in multiferroics
Authors: Mochizuki Masahito 
Published: October 2019

Abstract
Magnetic skyrmions, nanoscopic spin vortices carrying a quantized topological number in chiral-lattice magnets, are recently attracting great research interest. Although magnetic skyrmions had been observed only in metallic chiral-lattice magnets such as B20 alloys in the early stage of the research, their realization was discovered in 2012 also in an insulating chiral-lattice magnet

. A characteristic of the insulating skyrmions is that they can host multiferroicity, that is, the noncollinear magnetization alignment of skyrmion induces electric polarizations in insulators with a help of the relativistic spin-orbit interaction. It was experimentally confirmed that the skyrmion phase in

is indeed accompanied by the spin-induced ferroelectricity. The resulting strong magnetoelectric coupling between magnetizations and electric polarizations can provide us with a means to manipulate and activate magnetic skyrmions by application of electric fields. This is in sharp contrast to skyrmions in metallic systems, which are driven through injection of electric currents. The magnetoelectric phenomena specific to the skyrmion-based multiferroics are attracting intensive research interest, and, in particular, those in dynamical regime are widely recognized as an issue of vital importance because their understanding is crucial both for fundamental science and for technical applications. In this article, we review recent studies on multiferroic properties and dynamical magnetoelectric phenomena of magnetic skyrmions in insulating chiral-lattice magnet

. It is argued that the multiferroic skyrmions show unique resonant excitation modes of coupled magnetizations and polarizations, so-called electromagnon excitations, which can be activated both magnetically with a microwave magnetic field and electrically with a microwave electric field. The interference between these two activation processes gives rise to peculiar phenomena in the gigahertz regime. As its representative example, we discuss a recent theoretical prediction of unprecedentedly large nonreciprocal directional dichroism of microwaves in the skyrmion phase of

. This phenomenon can be regarded as a one-way window effect on microwaves, that is, the extent of microwave absorption changes significantly when its incident direction is reversed. This dramatic effect was indeed observed by subsequent experiments. These studies demonstrated that the multiferroic skyrmions can be a promising building block for microwave devices.
Controlling of light with electromagnons

Published: October 2019

Abstract
Magnetoelectric coupling in multiferroic materials opens new routes to control the propagation of light. The new effects arise due to dynamic magnetoelectric susceptibility that cross-couples the electric and magnetic fields of light and modifies the solutions of Maxwell equations in media. In this paper, two major effects will be considered in detail: optical activity and asymmetric propagation. In case of optical activity the polarization plane of the input radiation rotates by an angle proportional to the magnetoelectric susceptibility. The asymmetric propagation is a counter-intuitive phenomenon and it represents different transmission coefficients for forward and backward directions. Both effects are especially strong close to resonance frequencies of electromagnons, i. e. excitations in multiferroic materials that reveal simultaneous electric and magnetic character.
Probing local order in multiferroics by transmission electron microscopy
Authors: Campanini Marco , Erni Rolf , Rossell Marta D. 
Published: October 2019

AbstractThe ongoing trend toward miniaturization has led to an increased interest in the magnetoelectric effect, which could yield entirely new device concepts, such as electric field-controlled magnetic data storage. As a result, much work is being devoted to developing new robust room temperature (RT) multiferroic materials that combine ferromagnetism and ferroelectricity. However, the development of new multiferroic devices has proved unexpectedly challenging. Thus, a better understanding of the properties of multiferroic thin films and the relation with their microstructure is required to help drive multiferroic devices toward technological application. This review covers in a concise manneradvancedanalytical imaging methods based on (scanning) transmission electron microscopy which can potentially be used to characterize complex multiferroic materials. It consists of a first broad introduction to the topic followed by a section describing the so-called phase-contrast methods, which can be used to map the polar and magnetic order in magnetoelectric multiferroics at different spatial length scales down to atomic resolution. Section 3 is devoted to electron nanodiffraction methods. These methods allow measuring local strains, identifying crystal defects and determining crystal structures, and thus offer important possibilities for the detailed structural characterization of multiferroics in the ultrathin regime or inserted in multilayers or superlattice architectures. Thereafter, in Section 4, methods are discussed which allow for analyzing local strain, whereas in Section 5 methods are addressed which allow for measuring local polarization effects on a length scale of individual unit cells. Here, it is shown that the ferroelectric polarization can be indirectly determined from the atomic displacements measured in atomic resolution images. Finally, a brief outlook is given on newly established methods to probe the behavior of ferroelectric and magnetic domains and nanostructures during in situ heating/electrical biasing experiments. These in situ methods are just about at the launch of becoming increasingly popular, particularly in the field of magnetoelectric multiferroics, and shall contribute significantly to understanding the relationship between the domain dynamics of multiferroics and the specific microstructure of the films providing important guidance to design new devices and to predict and mitigate failures.

AbstractAdney et al. describe the complete and comprehensive codon substitution mutagenesis of human retrotransposon LINE-1 using a synthetic DNA approach. This experiment is the first of its kind for any transposon...Long Interspersed Nuclear Element-1 (LINE-1, L1) is the only autonomous active transposable element in the human genome. The L1-encoded proteins ORF1p and ORF2p enable the element to jump from one locus to another via a “copy-and-paste” mechanism. ORF1p is an RNA-binding protein, and ORF2p has endonuclease and reverse transcriptase activities. The huge number of truncated L1 remnants in the human genome suggests that the host has likely evolved mechanisms to prevent full L1 replication, and thereby decrease the proliferation of active elements and reduce the mutagenic potential of L1. In turn, L1 appears to have a minimized length to increase the probability of successful full-length replication. This streamlining would be expected to lead to high information density. Here, we describe the construction and initial characterization of a library of 538 consecutive trialanine substitutions that scan along ORF1p and ORF2p to identify functionally important regions. In accordance with the streamlining hypothesis, retrotransposition was overall very sensitive to mutations in ORF1p and ORF2p; only 16% of trialanine mutants retained near-wild-type (WT) activity. All ORF1p mutants formed near-WT levels of mRNA transcripts and 75% formed near-WT levels of protein. Two ORF1p mutants presented a unique nucleolar-relocalization phenotype. Regions of ORF2p that are sensitive to mutagenesis but lack phylogenetic conservation were also identified. We provide comprehensive information on the regions most critical to retrotransposition. This resource will guide future studies of intermolecular interactions that form with RNA, proteins, and target DNA throughout the L1 life cycle.

Dihydromyricetin promotes autophagy and attenuates renal interstitial fibrosis by regulating miR-155-5p/PTEN signaling in diabetic nephropathy
Authors: Guo Liming , Tan Kuibi , Luo Qun , Bai Xu 
Published: October 2019

Diabetic nephropathy (DN) is the most common complication of diabetes and is prone to kidney failure. Dihydromyricetin (DHM) has been reported to have a variety of pharmacological activities. This study aims to explore the effect of DHM on DN and the underlying molecular mechanism. An in vivo DN rat model was established. The degree of renal interstitial fibrosis (RIF) was detected by hematoxylin-eosin (HE) staining, Masson's trichrome staining, and immunohistochemistry (IHC). In vitro, NRK-52E cells were divided into four groups: normal glucose (NG), high glucose (HG), HG+DHM, and HG+rapamycin (autophagy inhibitor). The levels of autophagy- and fibrosis-related proteins were analyzed by western blotting. The expression of miR-155-5p and phosphatase and tensin homolog deleted on chromosome ten (PTEN) and their relationship were assessed by quantitative reverse transcription (qRT)-PCR and dual luciferase reporter gene assay. Our results showed that RIF was increased in DN rat model and in HG-induced NRK-52E cells. DHM treatment attenuated the increased RIF and also increased autophagy. MiR-155-5p expression was increased, while PTEN expression was decreased in DN rat and cell model, and DHM reversed both effects. Dual luciferase assay showed that PTEN was the target gene of miR-155-5p. DHM inhibited HG-induced fibrosis and promoted autophagy by inhibiting miR-155-5p expression in NRK-52E cells. In addition, DHM promoted autophagy by inhibiting the PI3K/AKT/mTOR signaling pathway. In conclusion, DHM promotes autophagy and attenuates RIF by regulating the miR-155-5p/PTEN signaling and PI3K/AKT/mTOR signaling pathway in DN.
