Neptuno Alegórico: emblemático arco en la obra de sor Juana
Authors: Ruiz Facundo 
Published: February 2013

ABSTRACT: Frequently but unevenly valued, sor Juana Inés de la Cruz’s (1648-1695) Neptuno alegórico [Allegorical Neptune] has received increased attention in recent years, as though —by virtue of its nature as «ephemeral art»— «that» art (emblematic) had become increasingly more meaningful than the fugacious situation from which it emerged. An exceptional text, the design of the triumphal archway that welcomed the new viceroy Tomás Antonio de la Cerda and his wife María Luisa Manrique de Lara in 1680, reveals not only the importance that sor Juana had already attained, to a great extent, as a writer, but also, and more emphatically, it shows the relevance of her public figure and, in a programatic sense, demonstrates a certain matrix for her literature. Therefore, this study seeks to analyze the Neptuno alegórico in depth in order to reveal the three passages manifested in it: the one that converts the author into a (problematically) public figure; the one that displays in such an erudite and artistic manner a certain way of conceiving and practicing literary writing in the public sphere; and, finally, the one that places «that» literature (by Sor Juana) on a «gilded» map of Hispano-American literature. KEY WORDS: sor Juana, Neptuno alegórico, Ttriumphal Arch, Ephemeral Art, Baroque RESUMEN: Histórica pero desigualmente valorado, el Neptuno Alegórico de sor Juana Inés de la Cruz (México, 1648-1695) ha recibido en los últimos años una atención creciente, como si —en su carácter de «arte efímero»— tuviera cada vez más sentido «ese» arte (emblemático) que la fugacidad (coyuntural) que lo motivó. Texto singular, el diseño del arco triunfal que recibió en 1680 al nuevo virrey Tomás Antonio de la Cerda y a su esposa, María Luisa Manrique de Lara, pone en evidencia no sólo la importancia de la escritora que ya era —en buena medida— sor Juana sino, más enfáticamente, la relevancia de su figura pública y, de forma programática, cierta matriz para su literatura. En este sentido, el presente trabajo se propone analizar detenidamente dicho texto a fin de concebir el pasaje triple allí manifiesto: el que convierte a esa escritora en una figura (problemáticamente) pública; el que exhibe tan erudita como artísticamente cierta forma de hacer y pensar la escritura literaria en el espacio público; y, finalmente, el que coloca «esa» literatura (sorjuanina) en un «áureo» mapa literario hispanoamericano.

AbstractThe microquasar GX 339-4 experienced an outburst in 2010. We focus on observations that are quasi-simultaneous with those made by INTEGRAL and RXTE in March–April 2010 with radio, NIR, optical and UV data. X-ray transients are extreme systems, often harboring a black hole, known to emit throughout the whole electromagnetic spectrum in outburst. We studied the source evolution and correlated changes in all wavelengths. The bolometric flux increased from 0.8 to 2.9 × 10−8 erg cm−2 s−1 while the relative contribution of the hot medium decreased. The radio, NIR and optical emission from jets was detected and observed to fade as the source softened; reprocessing in the disc was strong at the end.

Published: February 2013

AbstractThe unmatched X-ray resolution of Chandra allows probing the gas flow near quiescent supermassive black holes (BHs). The radius of BH gravitational influence on gas, called the Bondi radius, is resolved in Sgr A* and NGC 3115. Shallow accretion flow density profiles n ∝ r−β with β=0.7–1.0 were found for Sgr A* and NGC 3115 with the help of Chandra. We construct self-consistent models with gas feeding and dynamics from near the Bondi radius to the event horizon to explain the observations. Gas is mainly supplied to the region by hot colliding stellar winds. Small-scale feedback such as conduction effectively flattens the density profile from steep β=1.5 in a Bondi flow. We further constrain density and temperature profiles using the observed radio/sub-mm radiation emitted near the event horizon. We discuss the present state of our numerical model and its qualitative features, such as the role of the galactic gravitational potential and the random motion of wind-emitting stars.
The criteria for dynamical mass transfer of the main-sequence donor stars
Authors: Ge H. , Webbink R. F. , Chen X. , Han Z. 
Published: February 2013

AbstractMass transfer is very common in binary evolution and it dominates the evolutionary fate of binaries. Two crucial problems i.e. dynamical mass transfer and common envelope evolution, are not well understood yet. Here we focus on the first problem, and systematically show the critical mass ratio for dynamical mass transfer when the donor stars are still on the main sequence (MS).
Problems of Clustering of Radiogalaxies
Authors: Godłowski Włodzimierz , Pollo Agnieszka , Golbiak Jacek 
Published: February 2013

AbstractWe present the preliminary analysis of clustering of a sample of 1157 radio-identified galaxies from Machalski & Condon (1999). We found that for separations 2–15 h−1 Mpc their redshift space autocorrelation function ξ(s) can be approximated by the power law with the correlation length ~3.75h−1 Mpc and slope γ ~ 1.8. The correlation length for radiogalaxies is found to be lower and the slope steeper than the corresponding parameters of the control sample of optically observed galaxies. Analysis the projected correlation function Ξ(r) displays possible differences in the clustering properties between active galactic nuclei (AGN) and starburst (SB) galaxies.
The emission lines radiated from accretion disk in cataclysmic variables
Authors: He L. , Zhao Y. H. , Lv G. L. 
Published: February 2013

AbstractDuring the quiescent phases, the spectra of cataclysmic variables are studied. We model the fluxes by means of the photoionization code CLOUDY, and in the model it is assumed that the geometry of disks is cylindrical. Using this method, we input a series of reasonable parameters and get a spectral library.
The lifetime of contact binaries
Authors: Jiang D. K. , Han Z. W. , Yang L. H. , Li L. F. 
Published: February 2013

AbstractThe lifetime of contact binaries is an important parameter for studying the evolution of contact binaries. By reproducing the relative frequency of occurrence for contact binaries, we found that the lifetime of contact binaries decreases with increasing mass of the primaries. The lifetime of contact binaries is about 4%–10% of the main sequence lifetime of the primaries, and is about 0.006–0.65 Gyr. This suggests that the lifetime of contact binaries strongly depends on the mass of the primaries.
Optical Afterglows as Probes for the Central Engine and Fireball of Gamma-Ray Bursts
Authors: Li Liang , Liang En-Wei , Gao He , Zhang Bing 
Published: February 2013

AbstractWell-sampled optical lightcurves of 146 gamma-ray bursts (GRBs) are compiled from literature. We identify possible emission components based on our empirical fits and present statistical analysis for these components. We find that the flares are related to prompt emission, suggesting that they could have the same origin in different episodes. The shallow decay segment is not correlated with prompt gamma-rays. It likely signals a long-lasting injected wind from GRB central engines. Early after onset peak is closely related with prompt emission. The ambient medium density profile is likely n ∝ r−1. No correlation between the late re-brightening bump and prompt gamma-rays or the onset bump is found. They may be from another jet component.

AbstractThe connection between active galactic nuclei (AGN) and their hosts showed to be important for understanding the formation and evolution of active galaxies. Using X–ray and deep optical data, we study how morphology and colours are related to X–ray properties at redshifts z≤2.0 for a sample of > 300 X–ray detected AGN in the Subaru/XMM-Newton Deep Survey (SXDS; Furusawa et al. 2008) and Groth-Westphal Strip (GWS; Pović et al. 2009) fields. We performed our morphological classification using the galSVM code (Huertas-Company et al. 2008), which is a new method that is particularly suited when dealing with high-redshift sources. To separate objects between X–ray unobscured and obscured, we used X–ray hardness ratio HR(0.5-2 keV/2-4.5 keV). Colour-magnitude diagrams were studied in relationship to redshift, morphology, X–ray obscuration, and X–ray-to-optical flux ratio. Around 50% of X–ray detected AGN at z≤2.0 analysed in this work reside in spheroidal and bulge-dominated galaxies, while at least 18% have disk-dominated hosts. This suggests that different mechanisms may be responsible for triggering the nuclear activity. When analysing populations of X–ray detected AGN in both colour-magnitude (CMD) and colour-stellar mass diagrams (Figure 1), the highest number of sources is found to reside in the green valley at redshifts ≈ 0.5–1.5. For the first time we studied CMD of these AGN in relation to morphology and X–ray obscuration, finding that they can reside in both early- and late-type hosts, where both morphological types cover similar ranges of X–ray obscuration (Figure 1). Our findings appear to confirm some previous suggestions that X–ray selected AGN residing in the green valley represent a transitional population (e.g. Nandra et al. 2007, Silverman et al. 2008, Treister et al. 2009), quenching star formation by means of different AGN feedback mechanisms and evolving to red-sequence galaxies. More details on analysis and results presented here can be found in Pović et al. 2012.
Method to obtain hybrid rapid tools with elementary component assembly
Authors: Rivette M. , Mognol P. , Hascoet J.Y. 
Published: February 2013

PurposeThe purpose of this paper is to propose a method to obtain hybrid rapid tools with elementary component assembly.Design/methodology/approachThe authors' method proposes a functional representational model, starting with the product features, analyzed from three points of view: a feasibility analysis; a manufacturing analysis; and an assembly and synthesis analysis. This method, based on CAD STEP AP‐224 data, makes it possible to obtain an exhaustive list of solutions for the module. The work is illustrated with an industrial example. To construct the Assembly Identity Card (AIC) and test the various parameters that influence the quality of the injected parts, a hybrid injection mold has been produced. The methodology associated with the use of this AIC uses a “representation graph”, which makes it possible to propose a set of valid solutions for assembling the various tooling modules. This method is validated by industrial example.FindingsThe product part is decomposed into a multi‐component prototype (MCP), instead of being made as a single part, which optimizes the manufacturing process and enables greater reactivity during the development of the product.Research limitations/implicationsThe final goal is to propose a software assistant used in association with CAD system during the design of hybrid rapid tooling. An important work concerning the features recognition must be implemented. The assembly of the different parts of the hybrid rapid tooling must be considered and optimized.Practical implicationsThis method allows the selection of the best process technologies from manufacturing tools.Originality/valueThe analysis of manufacturing hybrid rapid tooling has not been studied previously.
An analysis view on password patterns of Chinese internet users
Authors: Yang Cheng , Hung Jui‐long , Lin Zhangxi 
Published: February 2013

PurposeIn December 2011, the National Computer Network Emergency Response Technical Team/Coordination Center of China reported the most serious user data leak in history which involved 26 databases with 278 million user accounts and passwords. After acquiring the user data from this massive information leak, this study has two major research purposes: the paper aims to reveal similarities and differences of password construction among four companies; and investigate how culture factors shape user password construction in China.Design/methodology/approachThis article analyzed real‐life passwords collected from four companies by comparing the following attributes: password length, password constitution, top 20 frequent passwords, character frequency distributions, string similarity, and password reuse.FindingsMajor findings include that: general users in China have a weaker sense of security than those in Western countries, which reflected in the password lengths, the character combinations and the content structures; password constitution preferences are different between users in Western countries and in China, where passwords are more similar to the Pinyin context and Chinese number homonym; and password reuse is very common in China. General users tend to reuse the same passwords and IT professionals tend to engage in Seed Password reuse.Research limitations/implicationsDue to the rapid growth of Internet users and e‐commerce markets in China, many online service providers may not pay enough attention to security issues, but focus instead on market expansion. Employees in these companies may not be well trained in information security, resulting in carelessness when handling security issues.Originality/valueThis is the first study which attempts to consider culture influences in password construction by analyzing real‐life datasets.
Nutrition products for preterm infants: Do they meet requirements? Discoveries from the infant enteral feeding tender
Authors: Gilroy Melissa , Page Denise 
Published: February 2013

AbstractAimThe objectives of the present study were to determine if products marketed for preterm and term infants in 2009 met the recommendations for these groups, and to review macronutrient, micronutrient and product specifications through the development of a novel and robust approach to the clinical nutrition component of the infant feeding tender.MethodsTender applicants were requested to provide information in a standardised format to allow product comparison. In total, 28 macronutrients and micronutrients for each formulation were tabulated and compared at standard feeding volumes with reasonable nutrient intakes for preterm infants and nutrient reference values for term infants. In addition, other product specifications were considered with current evidence. A weighing system was developed; meeting essential clinical nutrient requirements contributed a possible 80% and other product specifications, including desirable clinical requirements, contributed a possible 20% of the total score.ResultsNutrition products marketed for preterm infants varied in their ability to meet the reasonable nutrient intakes at usual intake volumes. All products tendered for the term infant category met the nutrient reference values at usual intake volumes.ConclusionIt cannot be assumed that products marketed for particular patient groups, such as preterm and term infants, meet the recommendations for that group. A review of enteral products addressing more than macronutrients and product specifications should be applied by all hospitals undergoing a feeding tender process for any patient group.

AbstractAcute kidney injury (AKI) induced by ischaemia and reperfusion (I/R) injury is a common and severe clinical problem. Vascular dysfunction, immune system activation and tubular epithelial cell injury contribute to functional and structural deterioration. The search for novel therapeutic interventions for I/R‐induced AKI is a dynamic area of experimental research. Pharmacological targeting of injury mediators and corresponding intracellular signalling in endothelial cells, inflammatory cells and the injured tubular epithelium could provide new opportunities yet may also pose great translational challenge. Here, we focus on signalling mediators, their receptors and intracellular signalling pathways which bear potential to abrogate cellular processes involved in the pathogenesis of I/R‐induced AKI. Sphingosine 1 phosphate (S1P) and its respective receptors, cytochrome P450 (CYP450)‐dependent vasoactive eicosanoids, NF‐κB‐ and protein kinase‐C (PKC)‐related pathways are representatives of such ‘druggable’ pleiotropic targets. For example, pharmacological agents targeting S1P and PKC isoforms are already in clinical use for treatment for autoimmune diseases and were previously subject of clinical trials in kidney transplantation where I/R‐induced AKI occurs as a common complication. We summarize recent in vitro and in vivo experimental studies using pharmacological and genomic targeting and highlight some of the challenges to clinical application of these advances.
Effect of Plating Technique on Periosteal Vasculature of the Radius in Dogs: A Cadaveric Study
Authors: Garofolo Stephen , Pozzi Antonio 
Published: February 2013

AbstractObjectiveTo (1) evaluate the normal extraosseous blood supply of the cranial aspect of the canine radius and (2) to compare the effects of minimally invasive (MIPO) and open plating technique on its preservation.Study DesignExperimental cadaveric study.Sample PopulationAdult canine thoracic limbs (n = 36) obtained from cadavers weighing 25–35 kg.MethodsTwelve unpaired limbs were used to study the normal extraosseous blood supply. Each limb was injected with blue latex and India ink, and then underwent microdissection. Twelve paired limbs were used to study the effects of the 2 surgical plating techniques. On each of the paired radii, either MIPO or open plating was performed. After surgery, limbs were prepared and injected using the same methodology as the normal limbs. The dorsal surface of the radius was divided into 4 zones. Extravasation and periosteal filling were scored and the results were compared between groups using the Wilcoxon matched‐pairs signed rank test; significance was set at P < .05.ResultsThe topography of the vasculature on the cranial aspect of the radius consisted of a complex network of periosteal vessels originating from the median, radial, caudal interosseous, and cranial interosseous arteries. Open plating caused significantly greater extravasation than MIPO (P = .0003). For each zone the MIPO group had significantly greater periosteal filling compared to those in the open plating group.ConclusionsIn this cadaveric model, based on the superior periosteal filling and vascular integrity, MIPO disrupted less periosteal vasculature of the canine radius than open plating.

ABSTRACT

Broadly neutralizing antibodies PG9 and PG16 effectively neutralize 70 to 80% of circulating HIV-1 isolates. In this study, the neutralization abilities of PG9 and PG16 were further enhanced by bioconjugation with aplaviroc, a small-molecule inhibitor of virus entry into host cells. A novel air-stable diazonium hexafluorophosphate reagent that allows for rapid, tyrosine-selective functionalization of proteins and antibodies under mild conditions was used to prepare a series of aplaviroc-conjugated antibodies, including b12, 2G12, PG9, PG16, and CD4-IgG. The conjugated antibodies blocked HIV-1 entry through two mechanisms: by binding to the virus itself and by blocking the CCR5 receptor on host cells. Chemical modification did not significantly alter the potency of the parent antibodies against nonresistant HIV-1 strains. Conjugation did not alter the pharmacokinetics of a model IgG in blood. The PG9-aplaviroc conjugate was tested against a panel of 117 HIV-1 strains and was found to neutralize 100% of the viruses. PG9-aplaviroc conjugate IC
50
s were lower than those of PG9 in neutralization studies of 36 of the 117 HIV-1 strains. These results support this new approach to bispecific antibodies and offer a potential new strategy for combining HIV-1 therapies.
Serotonin syndrome: pills, thrills and shoulder aches
Authors: Proudfoot Malcolm , Gormley Joe 
Published: February 2013

This case demonstrates an acute presentation of unwitnessed seizure causing typical injuries. Progress in hospital was complicated by worsening autonomic disturbance and agitation, typical for serotonin syndrome, suspected in light of recent selective serotonin reuptake inhibitor antidepressant initiation. Supportive care required treatment in the intensive care unit setting but full recovery ensued. This case not only reminds clinicians of the potential pitfalls in assessing postictal injured patients, but also that serotonin syndrome requires a high-index of diagnostic suspicion given the range of presenting features. Management ranges from simple withdrawal of the offending agent to specific therapies such as a cyproheptadine.
