ABSTRACT
We consider a modification of the restricted three-body problem where the primary (more massive body) is a triaxial rigid body and the secondary (less massive body) is an oblate spheroid and study periodic motions around the collinear equilibrium points. The locations of these points are first determined for 10 combinations of the parameters of the problem. In all 10 cases, the collinear equilibrium points are found to be unstable, as in the classical problem, and the Lyapunov periodic orbits around them have been computed accurately by applying known corrector–predictor algorithms. An extensive study on the families of three-dimensional periodic orbits emanating from these points has also been done. To find suitable starting points, for all the computed families, semianalytical solutions have been obtained, for both two- and three-dimensional cases, around the collinear equilibrium points using the Lindstedt–Poincaré method. Finally, the stability of all computed periodic orbits has been studied.

Genre, frontières du travail domestique et marges du salariat. Le cas des aides à domicile
Authors: Dussuet Annie 
Published: November 2016

Le mouvement de salarisation des femmes, concomitant à la tertiarisation, se traduit par une externalisation du travail domestique et par l’extension à la sphère publique du système normatif jusque-là caractéristique de la sphère privée. Cette redéfinition de frontière tend à déstabiliser les cadres du travail et de l’emploi, en particulier dans le secteur très féminisé des « services à la personne », tout en renouvelant les formes de la domination de genre.

« Mon digne successeur et ami » : Debret, Porto-Alegre et l’invention d’un héritage
Authors: Lima Valéria Alves Esteves 
Published: November 2016

La Bibliothèque nationale de Rio de Janeiro détient une liasse de lettres envoyées de Paris par Jean-Baptiste Debret à Manuel de Araújo Porto-Alegre, entre 1837 et 1844. Le premier est peintre d’histoire et membre de la colonie d’artistes et d’ingénieurs arrivée au Brésil en 1816, et désignée sous le nom de « Mission artistique française ». Le second, son élève à l’Académie impériale des beaux-arts de Rio de Janeiro, s’est distingué dans l’histoire de l’art et de la culture brésilienne du XIXe siècle. Cet article s’inspire des catégories analytiques de Reinhart Koselleck, et propose une interprétation des relations de Debret avec le Brésil après son retour en France, ainsi que de ses efforts pour impliquer Porto-Alegre dans ses projets, ce qui est particulièrement manifeste à la lecture de ses lettres.The National Library in Rio de Janeiro holds a set of letters sent from Paris by Jean-Baptiste Debret to Manuel de Araújo Porto-Alegre between 1837 and 1844. The former was a historical painter and member of the group of French artists and engineers who arrived in Brazil in 1816, the so-called “French Artistic Mission.” The latter was his student at the Imperial Academy of Fine Arts in Rio de Janeiro and a renowned figure in the history of Brazilian art and culture in the nineteenth century. Inspired by the analytical categories of Reinhart Koselleck, this article presents an interpretation of Debret’s relations with Brazil after his return to France and of his efforts to involve Porto-Alegre in his projects, a topic that stands out in the epistolary set.
The Syk–NFAT–IL-2 Pathway in Dendritic Cells Is Required for Optimal Sterile Immunity Elicited by Alum Adjuvants

Abstract
Despite a long history and extensive usage of insoluble aluminum salts (alum) as vaccine adjuvants, the molecular mechanisms underpinning Ag-specific immunity upon vaccination remain unclear. Dendritic cells (DCs) are crucial initiators of immune responses, but little is known about the molecular pathways used by DCs to sense alum and, in turn, activate T and B cells. In this article, we show that alum adjuvanticity requires IL-2 specifically released by DCs, even when T cell secretion of IL-2 is intact. We demonstrate that alum, as well as other sterile particulates, such as uric acid crystals, induces DCs to produce IL-2 following initiation of actin-mediated phagocytosis that leads to Src and Syk kinase activation, Ca2+ mobilization, and calcineurin-dependent activation of NFAT, the master transcription factor regulating IL-2 expression. Using chimeric mice, we show that DC-derived IL-2 is required for maximal Ag-specific proliferation of CD4+ T cells and optimal humoral responses following alum-adjuvanted immunization. These data identify DC-derived IL-2 as a key mediator of alum adjuvanticity in vivo and the Src–Syk pathway as a potential leverage point in the rational design of novel adjuvants.

Abstract
Lung fibroblasts are key structural cells that reside in the submucosa where they are in contact with large numbers of CD4+ Th cells. During severe viral infection and chronic inflammation, the submucosa is susceptible to bacterial invasion by lung microbiota such as nontypeable Haemophilus influenzae (NTHi). Given their proximity in tissue, we hypothesized that human lung fibroblasts play an important role in modulating Th cell responses to NTHi. We demonstrate that fibroblasts express the critical CD4+ T cell Ag-presentation molecule HLA-DR within the human lung, and that this expression can be recapitulated in vitro in response to IFN-γ. Furthermore, we observed that cultured lung fibroblasts could internalize live NTHi. Although unable to express CD80 and CD86 in response to stimulation, fibroblasts expressed the costimulatory molecules 4-1BBL, OX-40L, and CD70, all of which are related to memory T cell activation and maintenance. CD4+ T cells isolated from the lung were predominantly (mean 97.5%) CD45RO+ memory cells. Finally, cultured fibroblasts activated IFN-γ and IL-17A cytokine production by autologous, NTHi-specific lung CD4+ T cells, and cytokine production was inhibited by a HLA-DR blocking Ab. These results indicate a novel role for human lung fibroblasts in contributing to responses against bacterial infection through activation of bacteria-specific CD4+ T cells.

Abstract
Vγ9Vδ2 T cell activation plays an important role in antitumor and antimicrobial immune responses. However, there are conditions in which Vγ9Vδ2 T cell activation can be considered inappropriate for the host. Patients treated with aminobisphosphonates for hypercalcemia or metastatic bone disease often present with a debilitating acute phase response as a result of Vγ9Vδ2 T cell activation. To date, no agents are available that can clinically inhibit Vγ9Vδ2 T cell activation. In this study, we describe the identification of a single domain Ab fragment directed to the TCR of Vγ9Vδ2 T cells with neutralizing properties. This variable domain of an H chain–only Ab (VHH or nanobody) significantly inhibited both phosphoantigen-dependent and -independent activation of Vγ9Vδ2 T cells and, importantly, strongly reduced the production of inflammatory cytokines upon stimulation with aminobisphosphonate-treated cells. Additionally, in silico modeling suggests that the neutralizing VHH binds the same residues on the Vγ9Vδ2 TCR as the Vγ9Vδ2 T cell Ag-presenting transmembrane protein butyrophilin 3A1, providing information on critical residues involved in this interaction. The neutralizing Vγ9Vδ2 TCR VHH identified in this study might provide a novel approach to inhibit the unintentional Vγ9Vδ2 T cell activation as a consequence of aminobisphosphonate administration.
Evaluating the Effect of SMT Material & Process Variables on Voiding Under QFNs
Authors: Judd Brandon , Durham Maria 
Published: November 2016

Abstract
Voiding under bottom terminated components (BTCs), such as quad-flat no-lead (QFN) components, is a problem which many circuit board assembly houses face on a daily basis. Such components have become very popular in circuit board assembly due to many of their benefits, including their small form factor, excellent thermal and electrical performance, easy PCB trace routing, and reduced lead inductance. Outgassing of flux in the solder paste used to attach QFNs to the PCB during reflow causes voiding under the components, as the gasses cannot escape because there is virtually no standoff under the QFNs. Voiding can have several serious effects on the performance of QFNs including reduced mechanical strength of the solder joint and hot spots under the QFN thermal pad because the voids do not conduct heat well. There are many process methods which are utilized in an attempt to mitigate the voiding issue, such as windowpane stencil designs and reflow profile. In this study, we will evaluate the effect of several other variables on voiding under QFNs, including solder paste powder mesh size, PCB surface metallization, and the reflow environment.

Atrial flutter regression in HIV-associated pulmonary arterial hypertension after treatment with bosentan

Published: November 2016

Pulmonary arterial hypertension (PAH) is a rare condition characterized by an increase in pulmonary arterial resistance leading to right heart failure and death. Arrhythmias are a growing problem in PAH; therefore, maintenance of sinus rhythm is considered to be an important treatment aim in these patients. We described the case of a 46-year-old woman with HIV-associated pulmonary arterial hypertensionÂ who developed atrial flutter. After treatment with bosentan, it was observed a significant improvement in clinical and haemodynamic parameters. In addition, the AFL, which had previously persisted to both antiarrhythmic drug therapy and electrical stimulation, and had recurred after transthoracic electrical cardioversion, disappearedÂ in absence of any antiarrhythmic drug. Though the precise factors responsible for supraventricular arrhythmogenesis are still largely obscure, it is likely that initiation and maintenance of AFL may depend on all the conditions that can lead to increase in right atrial pressure, size, and wall stress, such as PAH. In our case, bosentan reduced both mean pulmonary artery pressure (mPAP) value and right heart chambers pressures. Therefore, it is conceivable that with the anatomical substrate needed for the maintenance of AFL being disappeared, sinus rhythm was restored.

Published: November 2016

Abstract. Aerosols from open-land fires could significantly perturb the global radiation balance and induce climate change. In this study, Community Atmosphere Model version 5 (CAM5) with prescribed daily fire aerosol emissions is used to investigate the spatial and seasonal characteristics of radiative effects (REs, relative to the case of no fires) of open-fire aerosols including black carbon (BC) and particulate organic matter (POM) from 2003 to 2011. The global annual mean RE from aerosol–radiation interactions (REari) of all fire aerosols is 0.16 ± 0.01 W m−2 (1σ uncertainty), mainly due to the absorption of fire BC (0.25 ± 0.01 W m−2), while fire POM induces a small effect (−0.05 and 0.04 ± 0.01 W m−2 based on two different methods). Strong positive REari is found in the Arctic and in the oceanic regions west of southern Africa and South America as a result of amplified absorption of fire BC above low-level clouds, in general agreement with satellite observations. The global annual mean RE due to aerosol–cloud interactions (REaci) of all fire aerosols is −0.70 ± 0.05 W m−2, resulting mainly from the fire POM effect (−0.59 ± 0.03 W m−2). REari (0.43 ± 0.03 W m−2) and REaci (−1.38 ± 0.23 W m−2) in the Arctic are stronger than in the tropics (0.17 ± 0.02 and −0.82 ± 0.09 W m−2 for REari and REaci), although the fire aerosol burden is higher in the tropics. The large cloud liquid water path over land areas and low solar zenith angle of the Arctic favor the strong fire aerosol REaci (up to −15 W m−2) during the Arctic summer. Significant surface cooling, precipitation reduction and increasing amounts of low-level cloud are also found in the Arctic summer as a result of the fire aerosol REaci based on the atmosphere-only simulations. The global annual mean RE due to surface-albedo changes (REsac) over land areas (0.03 ± 0.10 W m−2) is small and statistically insignificant and is mainly due to the fire BC-in-snow effect (0.02 W m−2) with the maximum albedo effect occurring in spring (0.12 W m−2) when snow starts to melt.

“Mesmeric Revelation”: Art as Hypnosis
Authors: Gillespie Zane 
Published: November 2016

Abstract
This article explores the relationship between reader and narrative purpose in Poe's “Mesmeric Revelation,” arguing that this relationship bears resemblance to altered-state theories of hypnosis. It challenges predictable interpretations to open a new avenue for understanding the art of fiction. Primary emphasis is given to the reduced peripheral awareness experienced by readers. The cultivation of this focused attention, according to Poe's “The Philosophy of Composition,” is essential for creating effective artistic products.
Poe's Academic Editions in Spain within the First Fifteen Years of the Twenty-First Century
Authors: Correoso-Rodenas José Manuel 
Published: November 2016

Abstract
The purpose of this article is to show how the academic studies on Poe have been developed during the first fifteen years of the twenty-first century in Spain. To achieve this goal, the critical editions of Poe's works published from 2000 on, along with the works of literary criticism composed around Poe's life and works, will be analyzed. The year 2009, with the celebration of Poe's two-hundredth anniversary, was a turning point where many works were produced and many scholars focused on the works of Poe. Many books, articles, and new editions were produced in every research field; but they were not the only ones who made this effort of paying attention to Poe: Spanish students also got involved in some of the activities that took place during this year. Short stories, poems, Poe's life and travels, his influence in later authors on both sides of the Atlantic, and many other aspects were explored. This article will try to offer an overview of all these new publications and how they were received by the Spanish audience, being acquainted the idea that Poe was (and he is still) unknown for most Spaniards, who only have heard of him as an author of horror stories.
Trauma and the Uncanny in Edgar Allan Poe's “Ligeia” and “The Fall of the House of Usher”
Authors: Nadal Marita 
Published: November 2016

Abstract
As a disorder of memory and time, trauma implies a crisis of representation, of history and truth. It remains in the mind like an intruder or a ghost, foregrounding the disjunction between the present and a primary experience of the past that can never be captured. Like trauma, the uncanny implies haunting, uncertainty, repetition, a tension between the known and the unknown, and the intrusive return of the past. Taking the characteristics of these concepts as the point of departure, this paper analyzes Poe's Gothic tales “Ligeia” and “The Fall of the House of Usher,” and explores the close relationship between trauma and the uncanny in both of them. Thus the protagonists of these tales experience the desire to know and the fear of doing so—the basic dilemma at the heart of traumatic experience—and are haunted by memories of a remote and repressed past not recoverable by conscious means but which determines their life in the present. The paper discusses trauma and the uncanny in the light of trauma theory, psychoanalysis, and Gothic criticism, pointing out the centrality of memory and the notion of origins.
