Breaking the Myth: Bocángel's New Narcissus
Authors: Mercado Leticia 
Published: August 2018

Abstract
Gabriel Bocángel (1603–1658) gives the Ovidian myth of Narcissus a baroque twist in a game of mirrored images, voices, and silences. In redondilla LX, Celia looks into a mirror that breaks suddenly, multiplying her image into miniature portraits. Unlike Ovid's version of the story, it is not the lady who, like Narcissus, dies, enraptured in self-contemplation, but the lookingglass itself. Sonnet XII represents the “death” of the glass as the breaking of both its surface and its silence. The glass, now endowed with a voice, turns into a true mirror that echoes the message of desengaño: not only that suffering is the inevitable consequence of unfulfilled carnal desire, but also that beauty and artistic endeavor are both fragile and futile.
El anonimato como performance textual: ‘Clarinda’ y Amarilis reconsideradasAnonimity as Textual Performance: Reconsidering ‘Clarinda’ and Amarilis
Authors: Barco Valeria del 
Published: August 2018

Abstract
This article reconsiders anonymity in the works of the Peruvian poets known as ‘Clarinda’ and Amarilis. By analyzing this topic from the theory of reception, I argue that far from experiencing the lack of an author as a problem, we can understand it in the context of production and textual reception as planned by the poets. I propose that if anonymity in a text is a conscious choice made by the author, this lack of signature can be thought as a textual strategy purposefully employed by the producer of the text. Thus, both poets transform the social practice of the tapada into a textual strategy of freedom and expression.
Primero sueño y Segundo sueño, un diálogo poético trasatlánticoPrimero sueño and Segundo sueño, a Transatlantic Poetic Dialogue
Authors: Cortés-Vélez Dinorah 
Published: August 2018

Abstract
In Antología poética en honor a Góngora (1927), Gerardo Diego highlights the Gongorism of Sor Juana's First Dream and describes her verses as “convoluted.” In Homenaje a Sor Juana Inés de la Cruz (1952), Diego includes a poem of his own entitled Second Dream, which is a tribute to the First Dream. The present essay focuses on Diego's textual dialogue with basis on these two divergent moments, in order to demonstrate that reticence (first moment) and reappropriation (second moment) are representative of an effort of self-assertion of the Neo-Gongorist poet. Hans Robert Jauss's concept of ‘reception aesthetics’ allows examination of the aesthetic distance between the First Dream and the Second Dream in view of the disparity between the horizons of expectations of both poets. I propose, however, that it is necessary to examine this aesthetic distance with a reading that takes into account the variable of gender.

Mode på mode på museerne! Om nye tendenser og udstillingsmåder
Authors: Melchior Marie Riegels 
Published: August 2018

Det sker i England i særdeleshed, men tendensen er også at finde i det øvrige Europa og Nordamerika. At udstille, indsamle, bevare og forske i mode (tøj) er blevet et populært og udbredt fænomen blandt både kunst- og kulturhistoriske museer. Udviklingen giver anledning til at spørge, hvilken plads tildeles moden på museerne? Hvorfor sker det netop nu? I hvilken retning går udviklingen? Det er spørgsmål, som tages op i denne artikel, hvor også en nylig, avantgarde modeudstilling på The Victoria and Albert Museum i London, særligt fremhæves. Det drejer sig om udstillingen ”Spectres: When Fashion Turns Back”, kurateret af modemuseologen Judith Clark.
Øjenåbner – om projekteringen af Eyebeam Atelier i New York City
Authors: Nielsen Simon Glinvad 
Published: August 2018

This paper offers an introduction to the planning of a new museum in New York City: The Eyebeam Gallery. The museum will evolve around the making of di- gital art. The ambition of the new museum will be to bring together artists and museum visitors, thus creating a polyphony of voices articulating art forms that are completely new to the world.The architects involved in the project are Diller + Scofidio. So far they have mainly been concerned with the production of experimental works both in Europe and the US. One important point in the building of the Eyebeam Gallery is that the development of new art forms requires the invention of a new form of museum building. With this in mind Diller + Scofidio will design a building which focuses on relationships between new media art and the spaces that will enable and support these relationships. In the building housing the Eyebeam Gallery we can expect a museum with a strong emphasis on the physical experience of digital artwork. Futhermore, we can expect a ”site-specific” (Diller + Scofidio) museum. A building which can be seen as an organic enlargement of the surrounding city and as a mental enlargement of the New York community.

Kritisk kuratering. Udstillingspraksis udviklet i perspektiv af 1960- og 1970’ernes institutionskritik
Authors: Schwartz Charlotte Præstegaard 
Published: August 2018

This project description presents a curatorial practice that is part of a post.doc. investigating the contemporary cultural and political focus on participatory agendas. The curatorial practice takes a critical stand towards this focus, and suggests exhibition formats and educational strategies that address participation as critical reflection. The research unfolds in two exhibitions dealing with some of the notable tendencies within contemporary museological and curatorial studies, where museum and exhibition spaces are not considered as spaces of showcasing or conservation of art, but on the contrary are perceived as active spaces of production. Referring to Doreen Massey’s seminal work For Space – first published in 2005 – art spaces are thought of as a product of interrelations and recognised as always being under construction. In the research project institutional critique from the 1960s and 1970s avant-gardes is used as an analytical approach and as a method of spatial and political criticism and articulation that can be applied not only to the art world, but to spaces and institutions in general, which is a point made by Simon Sheikh. The two exhibitions are not to be considered as institutional critique, but as critical exchanges with and about contemporary art. The exhibitions are made in collaboration with two non-commercial art spaces in Copenhagen and will be on show in the spring of 2017.
Circadian disruption and divergent microbiota acquisition under extended photoperiod regimens in chicken
Authors: Hieke Anne-Sophie Charlotte , Hubert Shawna Marie , Athrey Giridhar 
Published: August 2018

The gut microbiota is crucial for metabolic homeostasis, immunity, growth and overall health, and it recognized that early-life microbiota acquisition is a pivotal event for later life health. Recent studies show that gut microbiota diversity and functional activity are synchronized with the host circadian rhythms in healthy individuals, and circadian disruption elicits dysbiosis in mammalian models. However, no studies have determined the associations between circadian disruption in early life, microbiota colonization, and the consequences for microbiota structure in birds.
Chickens, as a major source of protein around the world, are one of the most important agricultural species, and their gut and metabolic health are significant concerns. The poultry industry routinely employs extended photoperiods (>18 hours’ light) as a management tool, and their impacts on the chicken circadian, its role in gut microbiota acquisition in early life, and consequences for later life microbiota structure remain unknown. In this study, the objectives were to a) characterize chicken circadian activity under two different light regimes (12/12 hours’ Light/Dark and 23/1 hours Light/Dark), b) characterize gut microbiota acquisition and composition in the first four weeks of life, c) determine if gut microbiota oscillate in synchrony with the host circadian, and d) to determine if fecal microbiota is representative of cecal microbiota. Expression of clock genes (clock, bmal1, and per2) were assayed, and fecal and cecal microbiota was characterized using 16s rRNA amplicon analyses from birds raised under two photoperiod treatments.
Chickens raised under 12/12 LD photoperiods exhibited rhythmic clock gene activity, which was absent in birds raised under the extended (23/1 LD) photoperiod. This study is also the first to report differential microbiota acquisition under different photoperiod regimes. Gut microbiota members showed a similar oscillating pattern as the host, but this association was not as strong as found in mammals. Finally, the fecal microbiota was found to be not representative of cecal microbiota membership and structure. This is one of the first studies to demonstrate the use of photoperiods to modulate microbiota acquisition, and show its potential utility as a tool to promote the colonization of beneficial microorganisms.

Published: August 2018

BackgroundGrowth arrest and DNA-damage-inducible protein 45 alpha (GADD45A) was previously found to be associated with risk of several kinds of human tumors. Here, we studied the expression and clinical significance of GADD45A in breast cancer.MethodsWe performed an immunohistochemical study of GADD45A protein from 419 breast cancer tissues and 116 adjacent non-neoplastic tissues.ResultsSignificantly high GADD45A expression were observed in breast cancer tissues compared with adjacent non-neoplastic tissues (P < 0.001) and were independently correlative with estrogen receptor negative (P = 0.028) and high Ki-67 index (P < 0.001). Kaplan–Meier survival analysis revealed that patients with high GADD45A expression levels had a worse long-term prognosis in triple negative breast cancer (P = 0.041), but it was not an independent prognostic factor in multivariate analysis (P = 0.058).ConclusionsGADD45A expression levels are significantly correlative with estrogen receptor status and Ki-67 index in human breast cancer. Patients with triple negative breast cancer might be stratified into high risk and low risk groups based on the GADD45A expression levels.
Trends in hepatocellular carcinoma research from 2008 to 2017: a bibliometric analysis
Authors: Miao Yan , Zhang Ying , Yin Lihong 
Published: August 2018

Objectives
To comprehensively analyse the global scientific outputs of hepatocellular carcinoma (HCC) research.

Methods
Data of publications were downloaded from the Web of Science Core Collection. We used CiteSpace IV and Excel 2016 to analyse literature information, including journals, countries/regions, institutes, authors, citation reports and research frontiers.

Results
Until March 31, 2018, a total of 24,331 papers in HCC research were identified as published between 2008 and 2017. Oncotarget published the most papers. China contributed the most publications and the United States occupied leading positions in H-index value and the number of ESI top papers. Llovet JM owned the highest co-citations. The keyword “transarterial chemoembolization” ranked first in the research front-line.

Conclusions
The amount of papers published in HCC research has kept increasing since 2008. China showed vast progress in HCC research, but the United States was still the dominant country. Transarterial chemoembolization, epithelial-mesenchymal transition, and cancer stem cell were the latest research frontiers and should be paid more attention.
Coherence
Authors: Hartemann F. V. , Wu Sheldon S. Q. , Baldis H. A. 
Published: August 2018

Herein we review the concept of coherence, with a special emphasis on electromagnetic coherence. The article is organized as follows. After a brief discussion of dispersion, the radiation characteristics of free electrons are described in some detail, within the framework of classical electrodynamics. For point charges, the radiation is always coherent because no cutoff is introduced. For extended charge distributions, however, there is a physical scale that sets the transition from coherent to incoherent radiation; this mechanism is discussed as well as spatial coherence (transverse modes), phase noise in free‐electron devices, nonlinear coherent scattering processes (Compton, Kapitza‐Dirac, ponderomotive), and radiative corrections. Next, the coupling of bound electrons to electromagnetic fields in quantum systems, as exemplified by the atomic laser, is reviewed, together with recent major advances in this field, including chirped pulse amplification (CPA), temporal shaping and imaging, and femtosecond (10−15 s) optics. A “chirped” pulse is characterized by a frequency that has temporal dependence.The important question of whether coherence implies or requires monochromaticity is also addressed. In a classic paper, Roy J. Glauber introduced higher order correlation functions, and demonstrated that coherent fields can be generated with arbitrary Fourier spectra. This formalism is presented in detail in a monograph by Leonard Mendel and Emil Wolf and will be summarized here. Finally, other topics in quantum optics and laser‐plasma interaction physics, related to the general concept of coherence, are briefly discussed, including nonlinear processes, phase conjugation, squeezed states, four‐wave mixing, and decoherence.

AbstractSimilar to heterostructures composed of different materials, possessing unique properties due to the synergistic effect between different components, the crystal‐phase heterostructures, one variety of hetero‐phase structures, composed of different crystal phases in monometallic nanomaterials are herein developed, in order to explore crystal‐phase‐based applications. As novel hetero‐phase structures, amorphous/crystalline heterostructures are highly desired, since they often exhibit unique properties, and hold promise in various applications, but these structures have rarely been studied in noble metals. Herein, via a one‐pot wet‐chemical method, a series of amorphous/crystalline hetero‐phase Pd nanosheets is synthesized with different crystallinities for the catalytic 4‐nitrostyrene hydrogenation. The chemoselectivity and activity can be fine‐tuned by controlling the crystallinity of the as‐synthesized Pd nanosheets. This work might pave the way to preparing various hetero‐phase nanostructures for promising applications.

AbstractBlinding disorders of the outer retina involve dysfunction and degeneration of photoreceptors. One potential approach to treat these forms of blindness is to repopulate the outer retina via a simple bolus injection of donor photoreceptors. However, this may not be ideal due to the highly polarized organization of photoreceptors that include apical light sensing photopigments and basal axon terminals. Furthermore, bolus injections create uncertainty with regard to the area, density, and retention of donor cells. Here, a novel and robust microfabrication process is developed to create 3D, micrometer‐sized complex structures in ultrathin and biocompatible elastomer films (nonbiodegradable polydimethylsiloxane and biodegradable poly(glycerol‐sebacate)) that can serve as polarizable photoreceptor delivery scaffolds, consisting of an array of cup‐shaped photoreceptor capture wells that funnel into a microchannel. This “wine glass” scaffold design promotes efficient capture of human pluripotent stem‐cell‐derived photoreceptor cell bodies and guidance of basal axon extensions, ultimately achieving a uniform level of organization and polarization that is not possible with bolus injections or previously described scaffolds. In addition to future therapeutic applications, our scaffold design and materials provide a platform to generate reproducible and scalable in vitro models of photoreceptor‐based diseases.

AbstractDiverse alkenylboronic acids react smoothly with various sp3‐carbon electrophiles such as unactivated alkyl triflates in the presence of mild bases such as K3PO4. The reaction protocol is very mild and thereby enables high functional group tolerance. This transition metal‐free condition is orthogonal towards the classic transition metal catalyzed Suzuki coupling.magnified image

Dynamic behavior and damping characteristics of carbon black polymer composites at high strain rates
Authors: Akl Wael , Baz Amr M. 
Published: August 2018

AbstractThe dynamic stress–strain behavior and the damping characteristics of carbon black (CB)/polymer composites at high strain rates are measured using the split Hopkinson pressure bar. These characteristics are determined for polyurethane impregnated with 20% CB nanoparticles and compared with those of pristine polyurethane at strain rates ranging between 2,400 and 7,000 s−1. The obtained results indicate that the CB/polymer composites exhibit highly hysteretic stress–strain characteristics and have high storage modulus as well as high loss factor as compared to pristine polyurethane polymers. With such characteristics, the CB/polymer composites are observed to dissipate energy much higher than that dissipated by pristine polymers.
The influence of biological affinity and sex on morphometric parameters of the clavicle in a South African sample
Authors: Scott Shelby , Peckmann Tanya R. , Alblas Mandi (Amanda) 
Published: August 2018

AbstractObjectivesThe present study aims to investigate the influence of environmental and functional factors associated with biological affinity and musculature on sexual dimorphism of the clavicle, and to develop population‐specific methods of sex estimation from the clavicle.MethodsThe maximum length of the clavicle (MAXL), the sagittal diameter of the clavicle (SAGD), and the vertical diameter of the clavicle (VERD) were measured. The left clavicles of 198 South African coloured individuals (108 males and 90 females) were examined.ResultsOverall, the results of this study indicate that the SAGD of the clavicle is more sexually dimorphic than the VERD in the South African coloured sample. When the black American, white American, and Greek discriminant functions were applied to the South African coloured metric data, females were more accurately classified than males overall. Population‐specific discriminant functions were created for the South African coloured sample. The original accuracy showed that females (85.5%) were more accurately classified than males (78.1%). Overall, the multivariate discriminant function demonstrated a higher correct classification of South African coloureds than the univariate discriminant functions. The results also suggest that univariate discriminant function equations are more accurate for sex estimation than univariate sectioning points in the South African coloured sample.ConclusionsOverall, the results of the present study indicate that the clavicle is an accurate predictor of sex and its dimensions are population‐specific. Therefore, discriminant functions of the clavicle should only be used for sex estimation in forensic anthropology with the populations from which they were derived. © 2018 Wiley Periodicals, Inc.
The Uncertain Limits Between Classical and Quantum Physics: Optical Dispersion and Bohr's Atomic Model
Authors: Jordi Taltavull Marta 
Published: August 2018

AbstractIt is commonplace to recount the history of quantum physics on the basis of phenomena that have found no satisfactory explanation in the context of so‐called classical physics. This is the case of, for example, blackbody radiation, the photoelectric effect, specific heats, and series of spectral lines. This story goes in another direction: new knowledge about quantum physics not only emerged from the need to explain new phenomena that conflicted with old theoretical structures, but also from the attempts to provide a quantum explanation of phenomena, like optical dispersion, which for a long time had found a very convincing explanation in old physical models, such as the resonance model. The boundary between classical and quantum domains of knowledge was not fixed a priori, but historically negotiated in the context of specific problems, including the problem of optical dispersion.
