description: We consider the hypothesis of a limiting minimal curvature in gravity as a way to construct a class of theories exhibiting late-time cosmic acceleration. Guided by the minimal curvature conjecture (MCC) we are naturally lead to a set of scalar tensor theories in which the scalar is non-minimally coupled both to gravity and to the matter Lagrangian. The model is compared to the Lambda Cold Dark Matter concordance model and to the observational data using the gold SNeIa sample of Riess et. al. (2004). An excellent fit to the data is achieved. We present a toy model designed to demonstrate that such a new, possibly fundamental, principle may be responsible for the recent period of cosmological acceleration. Observational constraints remain to be imposed on these models.

description: We present a catalog of extended low-surface-brightness galaxies (LSBGs) identified in the Wide layer of the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP). Using the first ${\sim}$200 deg$^2$ of the survey, we have uncovered 781 LSBGs, spanning red ($g-i\geq0.64$) and blue ($g-i<0.64$) colors and a wide range of morphologies. Since we focus on extended galaxies ($r_\mathrm{eff}=2.5$-$14^{\prime\prime}$), our sample is likely dominated by low-redshift objects. We define LSBGs to have mean surface brightnesses $\barμ_\mathrm{eff}(g)>24.3$ mag arcsec$^{-2}$, which allows nucleated galaxies into our sample. As a result, the central surface brightness distribution spans a wide range of $μ_0(g)=18$-$27.4$ mag arcsec$^{-2}$, with 50% and 95% of galaxies fainter than 24.3 and 22 mag arcsec$^{-2}$, respectively. Furthermore, the surface brightness distribution is a strong function of color, with the red distribution being much broader and generally fainter than that of the blue LSBGs, and this trend shows a clear correlation with galaxy morphology. Red LSBGs typically have smooth light profiles that are well-characterized by single-component Sérsic functions. In contrast, blue LSBGs tend to have irregular morphologies and show evidence for ongoing star formation. We crossmatch our sample with existing optical, HI, and ultraviolet catalogs to gain insight into the physical nature of the LSBGs. We find that our sample is diverse, ranging from dwarf spheroidals and ultra-diffuse galaxies in nearby groups to gas-rich irregulars to giant LSB spirals, demonstrating the potential of the HSC-SSP to provide a truly unprecedented view of the LSBG population.

The Elusive American Dream: An Ecofeminist Reading of Race and Identity in Sandra Cisneros’ The House on Mango Street (1984)

description: Everyone knows the story of the big brick house with the white picket fence and the quiet subdivisions of identical houses and families. Regardless of race, class, religion, or gender, the lure of the ideal home appeals to the masses. Told with a fairytale quality, the American Dream possesses a magic that transcends space and time. For some groups, however, white fences are not the obvious boundaries. Instead, boundaries exist in the pigments of these people’s skin, the block they live on, or how many letters fill up their last name. In Sandra Cisneros’ novella The House on Mango Street (1984), the American Dream appears again, this time on a poverty-stricken, Hispanic street in Chicago, narrated by an adolescent, Mexican-American girl named Esperanza Cordero. Through the ecofeminist and ecocritical lenses, Cisneros utilizes Esperanza’s readings of houses and homes to comment on the commodity culture of dwellings, revealing how Esperanza’s perception of identity and selfhood is directly connected to the house of the American Dream, and further explores the function of “place,” the boundaries of space, and the power of penning new boundaries.

description: Two-dimensional atomic arrays exhibit a number of intriguing quantum optical phenomena, including subradiance, nearly perfect reflection of radiation and long-lived topological edge states. Studies of emission and scattering of photons in such lattices require complete treatment of the radiation pattern from individual atoms, including long-range interactions. We describe a systematic approach to perform the calculations of collective energy shifts and decay rates in the presence of such long-range interactions for arbitrary two-dimensional atomic lattices. As applications of our method, we investigate the topological properties of atomic lattices both in free-space and near plasmonic surfaces.

description: Experiments on bilayer graphene unveiled a fascinating realization of stacking disorder where triangular domains with well-defined Bernal stacking are delimited by a hexagonal network of strain solitons. Here we show by means of numerical simulations that this is a consequence of a structural transformation of the moiré pattern inherent of twisted bilayer graphene taking place at twist angles $θ$ below a crossover angle $θ^{\star}=1.2^{\circ}$. The transformation is governed by the interplay between the interlayer van der Waals interaction and the in-plane strain field, and is revealed by a change in the functional form of the twist energy density. This transformation unveils an electronic regime characteristic of vanishing twist angles in which the charge density converges, though not uniformly, to that of ideal bilayer graphene with Bernal stacking. On the other hand, the stacking domain boundaries form a distinct charge density pattern that provides the STM signature of the hexagonal solitonic network.

description: Many important proteins perform their physiological functions under allosteric control, whereby the binding of a ligand at a specific site influences the binding affinity at a different site. Allosteric regulation usually involves a switch in protein conformation upon ligand binding. The energies of the corresponding structures are comparable, and, therefore, the possibility that a structure determined by x-ray diffraction in the crystalline state is influenced by its intermolecular contacts, and thus differs from the solution structure, cannot be excluded. Here, we demonstrate that the quaternary structure of tetrameric human normal adult carbonmonoxy-hemoglobin can readily be determined in solution at near-physiological conditions of pH, ionic strength, and temperature by NMR measurement of (15)N-(1)H residual dipolar couplings in weakly oriented samples. The structure is found to be a dynamic intermediate between two previously solved crystal structures, known as the R and R2 states. Exchange broadening at the subunit interface points to a rapid equilibrium between different structures that presumably include the crystallographically observed states.

description: Supersymmetric scenarios with inverted mass hierarchy can be hard to observe at a hadron collider, particularly for the non-strongly interacting sector. We show how the production of stau-pairs via gauge boson fusion, along with hard jets in the high rapidity region, can be instrumental in uncovering the signatures of such scenarios. We demonstrate this both in a model-independent way and with reference to some specific, well-motivated models.

Discursive Crimes: Chicana Affect and Hegemonic Power in Eulogy for a Brown Angel by Lucha Corpi
Creators: name: Villanueva-Nieves, Natalia
Publisher: name: Ex-centric Narratives: Journal of Anglophone Literature, Culture and Media
Year: 2019

description: This article argues that the detective novel Eulogy for a Brown Angel (1992) by Chicana author Lucha Corpi is a complex theorization on the intimate relationship between hegemonic power and Chicana affect (a relationship that I call “hegemonic affect”). Eulogy for a Brown Angel is a complex, discursive formation in which master narratives collide with counter-discourses that challenge hegemonic power. Literary critics, such as Tim Libretti (1999), have analyzed Corpi’s novel as an example of how “multicultural detective fiction” disrupts the pro-capitalist, misogynist and racist ideologies of the classic U.S. hard-boiled narratives by incorporating the historical and political experiences of communities of color. In contrast to previous studies, my analysis focuses on how in Corpi’s novel these hegemonic formations crucially impact Chicana affects. The article pays special attention to how Chicana affects are damaged by master narratives that define power in terms of Anglo-Saxon whiteness, masculinity and heterosexuality. In addition, the present analysis argues that in order to resist hegemonic power, Chicanas in the novel advance affects that facilitate solidarity and alliances amongst women of color, enabling healing and the pursuit of social justice.

description: We have applied the residual dipolar coupling (RDC) method to investigate the solution quaternary structures of (2)H- and (15)N-labeled human normal adult recombinant hemoglobin (rHb A) and a low-oxygen-affinity mutant recombinant hemoglobin, rHb(alpha96Val-->Trp), both in the carbonmonoxy form, in the absence and presence of an allosteric effector, inositol hexaphosphate (IHP), using a stretched polyacrylamide gel as the alignment medium. Our recent RDC results [Lukin, J. A., Kontaxis, G., Simplaceanu, V., Yuan, Y., Bax, A., and Ho, C. (2003) Proc. Natl. Acad. Sci. U.S.A. 100, 517-520] indicate that the quaternary structure of HbCO A in solution is a dynamic ensemble between two previously determined crystal structures, R (crystals grown under high-salt conditions) and R2 (crystals grown under low-salt conditions). On the basis of a comparison of the geometric coordinates of the T, R, and R2 structures, it has been suggested that the oxygenation of Hb A follows the transition pathway from T to R and then to R2, with R being the intermediate structure [Srinivasan, R., and Rose, G. D. (1994) Proc. Natl. Acad. Sci. U.S.A. 91, 11113-11117]. The results presented here suggest that IHP can shift the solution quaternary structure of HbCO A slightly toward the R structure. The solution quaternary structure of rHbCO(alpha96Val-->Trp) in the absence of IHP is similar to that of HbCO A in the presence of IHP, consistent with rHbCO(alpha96Val-->Trp) having an affinity for oxygen lower than that of Hb A. Moreover, IHP has a much stronger effect in shifting the solution quaternary structure of rHbCO(alpha96Val-->Trp) toward the R structure and toward the T structure, consistent with IHP causing a more pronounced decrease in its oxygen affinity. The results presented in this work, as well as other results recently reported in the literature, clearly indicate that there are multiple quaternary structures for the ligated form of hemoglobin. These results also provide new insights regarding the roles of allosteric effectors in regulating the structure and function of hemoglobin. The classical two-state/two-structure allosteric mechanism for the cooperative oxygenation of hemoglobin cannot account for the structural and functional properties of this protein and needs to be revised.

description: The thermal properties of the surfaces of asteroids determine the magnitude of the drift rate cause by the Yarkovsky force. In the general case of Main Belt asteroids, the Yarkovsky force is indirectly proportional to the thermal inertia, $Γ$. Following the proposed relationship between $Γ$ and asteroid diameter $D$, we find that asteroids' Yarkovsky drift rates might have a more complex size dependence than previous thought, leading to a curved family V-shape boundary in semi-major axis, a, vs. 1/$D$ space. This implies that asteroids are drifting faster at larger sizes than previously considered decreasing on average the known ages of asteroid families. The V-Shape curvature is determined for $>$25 families located throughout the Main Belt to quantify the Yarkovsky size-dependent drift rate. We find that there is no correlation between family age and V-shape curvature. In addition, the V-shape curvature decreases for asteroid families with larger heliocentric distances suggesting that the relationship between $Γ$ and $D$ is weaker in the outer MB possibly due to homogenous surface roughness among family members.

Woman Killing and Adoption in Alicia Gaspar de Alba’s Desert Blood: The Juárez Murders (2005)
Creators: name: Jiroutová Kynčlová, Tereza
Publisher: name: Ex-centric Narratives: Journal of Anglophone Literature, Culture and Media
Year: 2019

description: Alicia Gaspar de Alba’s novel Desert Blood: The Juárez Murders (2005) informs its readers about the serial feminicidal violence that has afflicted Ciudad Juárez, the twin town to El Paso, Texas. The novel is explicit about its feminist, political agenda and appeal to social justice. The article discusses details from the novel in which Gaspar de Alba portrays the Juárez murders in a compelling manner that employs Diana Russell’s, and Rosa Linda Fregoso and Cynthia Bejarano’s concepts of femi(ni)cide to provide a fictionalized, yet analytical, account of institutionalized gender violence targeting poor brown women. The article is innovative in its focus on Desert Bloods’ side characters, Cecilia and Elsa, who are key in Gaspar de Alba’s ability to convey the complex structure of how feminicides come to be perpetuated through the utilization of women’s bodies under capitalist and androcentric systems of social life. Concurrently, this article argues that a more careful and nuanced representation of intercountry adoption enhances Desert Blood’s feminist and ethical appeal, and accounts in a greater detail for the dynamic of power relations between the Chicana protagonist and the two Mexican side characters of Cecilia and Elsa.

description: Context.Spatially-resoved cicrumstellar disk spectrum and composition can provide valuable insights into the bulk composition of forming planets, as well as the mineralogical signatures that emerge during and after planet formation. Aims. We aim to systemically extract the RX~J1604.3-213010 (J1604 hereafter) protoplanetary disk in high-contrast imaging observations, and obtain its multi-band reflectance in visible to near-infrared wavelengths. Methods. We obtained coronagraphic observations of J1604 from the Keck Observatory's NIRC2 instrument, and archival data from the Very Large Telescope's SPHERE instrument. Using archival images to remove star light and speckles, we recovered the J1604 disk and obtained its surface brightness using forward modeling. Together with polarization data, we obtained the relative reflectance of the disk in $R$, $J$, $H$ ($H2$ and $H3$), $K$ ($K1$ and $K2$), and $L'$ bands spanning two years. Results. Relative to the J1604 star, the resolved disk has a reflectance of ${\sim}10^{-1}$~arcsec$^{-2}$ in $R$ through $H$ bands and ${\sim}10^{-2}$~arcsec$^{-2}$ in $K$ and $L'$ bands, showing a blue color. Together with other systems, we summarized the multi-band reflectance for 9 systems. We also identified varying disk geometry structure, and a shadow that vanished between June and August in 2015. Conclusions. Motivated by broad-band observations, the deployment of cutting-edge technologies could yield higher-resolution reflection spectra, thereby informing the dust composition of disks in scattered light in the future. With multi-epoch observations, variable shadows have the potential to deepen insights into the dynamic characteristics of inner disk regions.

“Brown Medeas:” Reconfiguring Mestizaje for the 21st Century
Creators: name: Delikonstantinidou, Aikaterini
Publisher: name: Ex-centric Narratives: Journal of Anglophone Literature, Culture and Media
Year: 2019

description: Whereas due attention has been granted to the “black Medeas” of the post-seventies U.S. stage, the “brown Medeas” of post-eighties/post-movimiento Chicana/o theatre have drawn much less scholarly interest. In response to this perceived lacuna in critical analysis, the present paper examines three revisions of Medea’s myth by Chicana/o theatre practitioners. “La Malinche,” by Carlos Morton (1996-97), “The Hungry Woman: A Mexican Medea,” by Cherríe Moraga (2000), and “Mojada: A Medea in Los Angeles,” by Luis Alfaro (2015), are taken up here as characteristic instances of contemporary Chicana/o reception of Greek tragic myth. The paper will argue that this new addition to Medea’s afterlife signals a crucial new development in Chicana/o theatre toward opening up to transcultural flows, syncrisis and negotiation, and, by extension, a shift in Chicana/o cultural and identity politics within the U.S. More specifically, we will discuss why and how revis(ion)ing Medea, correlating her with figures originating in indigenous mythico-cultural material (namely, La Malinche and La Llorona), remotivating her (and their) actions and even reimagining the outcomes of her (and their) stories in the mythoplays under consideration can be interpreted as a gesture toward alternative forms of affiliation, shifting political coalitions, and an emergent—decolonization-oriented but twenty-first-century-specific—mestizaje ethos and consciousness.

description: The basic premise of neuroprotection in acute stroke is the presence of salvageable tissue, but the spatiotemporal volume profiles of the penumbra and infarction remain poorly defined in preclinical animal models of acute stroke used to evaluate therapies for clinical application. Our aim was to define these profiles using magnetic resonance imaging (MRI) quantitative cerebral blood flow (CBF) and apparent diffusion coefficient (ADC) for dual-parameter voxel analysis in the rat suture permanent middle cerebral artery occlusion (pMCAO) model. Eleven male Sprague Dawley rats were subjected to pMCAO with MRI measurements of quantitative CBF and ADC at baseline, over the first 4 h (n=9) and at 7, 14, and 21 days (n=4). Voxel analysis of CBF and ADC was used to characterize brain tissue ischemic transitions. Penumbra, core, and hyperemic infarction volumes were significantly elevated (P

description: We report the detection of a Jupiter-mass planet in a 6.838 day orbit around the 1.28 solar mass subgiant HD 185269. The eccentricity of HD 185269b (e = 0.30) is unusually large compared to other planets within 0.1 AU of their stars. Photometric observations demonstrate that the star is constant to +/-0.0001 mag on the radial velocity period, strengthening our interpretation of a planetary companion. This planet was detected as part of our radial velocity survey of evolved stars located on the subgiant branch of the H-R diagram--also known as the Hertzsprung Gap. These stars, which have masses between 1.2 and 2.5 solar masses, play an important role in the investigation of the frequency of extrasolar planets as a function of stellar mass.

description: We investigate the dynamics of a microwave-driven Josephson junction capacitively coupled to a lumped element LC oscillator. In the regime of driving where the Josephson junction can be approximated as a Kerr oscillator, this minimal nonlinear system has been previously shown to exhibit a bistability in phase and amplitude. In the present study, we characterize the full phase diagram and show that besides a parameter regime exhibiting bistability, there is also a regime of self-oscillations characterized by a frequency comb in its spectrum. We discuss the mechanism of comb generation which appears to be different from those studied in microcavity frequency combs and mode-locked lasers. We then address the fate of the comb-like spectrum in the regime of strong quantum fluctuations, reached when nonlinearity becomes the dominant scale with respect to dissipation. We find that the nonlinearity responsible for the emergence of the frequency combs also leads to its dephasing, leading to broadening and ultimate disappearance of sharp spectral peaks. Our study explores the fundamental question of the impact of quantum fluctuations for quantum systems which do not possess a stable fixed point in the classical limit.

description: The binary system HESS J0632+057 was recently detected by {Fermi} to possess orbital modulated GeV emission. In this paper, we study the possibility that the compact companion of HESS J0632+057 is a pulsar. Under such a presumption, we focus on the high energy emission mechanism of this system, which is as follows. The pulsar companion travels through the circumstellar disc of the main sequence star twice in each orbit, when some of the matter is gravity-captured. The captured matter develops an accretion disc around the pulsar, and the soft photons from which are inverse Compton scattered by the pulsar wind as the GeV emission from the system. With proper choice of parameters, SED and light curve which are in accordance with observations can be produced. We predict that the light curve of GeV emission has two peaks, the larger one is at around 0.4 after the periastron (or 0.1 after the X-ray maximum), while the smaller one is between phases 0 and 0.1, with integrated flux one forth of the larger one.

description: Fragile X mental retardation protein (FMRP) is an RNA-binding protein that is required for the translational regulation of specific target mRNAs. Loss of FMRP causes Fragile X syndrome (FXS), the most common form of inherited mental retardation in humans. Understanding the basis for FXS has been limited because few in vivo targets of FMRP have been identified and mechanisms for how FMRP regulates physiological targets are unclear. We have previously demonstrated that Drosophila FMRP (dFMRP) is required in early embryos for cleavage furrow formation. In an effort to identify new targets of dFMRP-dependent regulation and new effectors of cleavage furrow formation, we used two-dimensional difference gel electrophoresis and mass spectrometry to identify proteins that are misexpressed in dfmr1 mutant embryos. Of the 28 proteins identified, we have identified three subunits of the Chaperonin containing TCP-1 (CCT) complex as new direct targets of dFMRP-dependent regulation. Furthermore, we found that the septin Peanut, a known effector of cleavage, is a likely conserved substrate of fly CCT and is mislocalized in both cct and in dfmr1 mutant embryos. Based on these results we propose that dFMRP-dependent regulation of CCT subunits is required for cleavage furrow formation and that at least one of its substrates is affected in dfmr1- embryos suggesting that dFMRP-dependent regulation of CCT contributes to the cleavage furrow formation phenotype.

description: Peripartum cardiomyopathy (PPCM) is a pregnancy-associated and life-threatening cardiac disease. However, the causes and pathogenesis are not fully understood. Accumulating studies show that cardiomyopathy often appears to be associated with elevated levels of β1-adrenoceptor (β1AR) antibodies, indicating a possible involvement of β1AR antibodies in the development of PPCM. We injected the antigen peptide segment of the β1AR into the postpartum Wistar rats to make the immune models and their cardiac function was detected by echocardiography. Also, the concentration of β1AR antibodies and apoptosis rate of left ventricular myocytes was tested by SA-ELISA, TUNEL, HE staining, qRT-PCR and western blot methods. Finally, the expression of peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) and its related proteins were examined by qRT-PCR and western blot methods. We found that the level of β1AR antibodies in the serum was significantly increased and the postpartum rats exhibited symptoms of PPCM after autoimmunity. Moreover, the expression of peroxisome PGC-1α, which was a master regulator of mitochondrial metabolism, and its downstream transcript vascular endothelial growth factor (VEGF), was decreased in autoimmune perinatal rats. In addition, the expression of the apoptosis factor caspase 3 as well as the apoptosis rate of left ventricular myocytes was significantly increased. The results suggested that the symptoms of PPCM that appeared in autoimmune perinatal rats may be due to the increase of β1AR antibodies, which inhibited the pathway associated with peroxisome PGC-1α.

description: We propose a flavour structure for the leptonic sector of the Standard Model, based on the idea of universality of Yukawa couplings, which accommodates all the experimental data on neutrino masses and mixing, at the same time predicting specific correlations between low energy measurable quantities, such as the ratio of neutrino squared mass differences, $|U_{13}|$, the leptonic Dirac phase, and the double-beta decay mass parameter. We also point out that it is possible, in this framework, to generate a sufficient amount of baryon asymmetry of the Universe through leptogenesis.

description: Recently we have shown that an architecture based on resistive processing unit (RPU) devices has potential to achieve significant acceleration in deep neural network (DNN) training compared to today's software-based DNN implementations running on CPU/GPU. However, currently available device candidates based on non-volatile memory technologies do not satisfy all the requirements to realize the RPU concept. Here, we propose an analog CMOS-based RPU design (CMOS RPU) which can store and process data locally and can be operated in a massively parallel manner. We analyze various properties of the CMOS RPU to evaluate the functionality and feasibility for acceleration of DNN training.

description: Membrane potential measurements using voltage-sensitive dyes (VSDs) have made important contributions to our understanding of electrophysiological properties of multi-cellular systems. Here, we report the development of long wavelength VSDs designed to record cardiac action potentials (APs) from deeper layers in the heart. The emission spectrum of styryl VSDs was red-shifted by incorporating a thienyl group in the polymethine bridge to lengthen and retain the rigidity of the chromophore. Seven dyes, Pittsburgh I to IV and VI to VIII (PGH I-VIII) were synthesized and characterized with respect to their spectral properties in organic solvents and heart muscles. PGH VSDs exhibited 2 absorption, 2 excitation and 2 voltage-sensitive emission peaks, with large Stokes shifts (> 100 nm). Hearts (rabbit, guinea pig and Rana pipiens) and neurohypophyses (CD-1 mice) were effectively stained by injecting a bolus (10-50 microl) of stock solution of VSD (2-5 mM) dissolved in in dimethylsulfoxide plus low molecular weight Pluronic (16% of L64). Other preparations were better stained with a bolus of VSD (2-5 mM) Tyrode's solution at pH 6.0. Action spectra measured with a fast CCD camera showed that PGH I exhibited an increase in fractional fluorescence, DeltaF/F = 17.5 % per AP at 720 nm with 550 nm excitation and DeltaF/F = - 6% per AP at 830 nm with 670 nm excitation. In frog hearts, PGH1 was stable with approximately 30% decrease in fluorescence and AP amplitude during 3 h of intermittent excitation or 1 h of continuous high intensity excitation (300 W Xe-Hg Arc lamp), which was attributed to a combination of dye wash out > photobleaching > dynamic damage > run down of the preparation. The long wavelengths, large Stokes shifts, high DeltaF/F and low baseline fluorescence make PGH dyes a valuable tool in optical mapping and for simultaneous mapping of APs and intracellular Ca(2+).

description: This article analyzes issues of gender, space, and ethnicity in three different pieces: Coco Fusco’s performance A Room of One’s Own: Women and Power in the New America (2006), the mural painting Latino America (1974) by the Las Mujeres Muralistas group, and the Venas de la Mujer installation (1976) at the LA Women’s Building by the Las Chicanas group. Though created in two different temporal contexts, the three pieces are connected by Virginia Woolf’s idea of the space as “room of one’s own,” and thus share an understanding of the complexity of issues, such as female creativity, the portrayal of/appropriation by women of spaces traditionally considered to be masculine, and the ephemerality of certain artistic media. By studying the three pieces in their geographical, social, and artistic context, I intend to demonstrate that issues denounced by the Chicano Civil Rights Movement (also known as El Movimiento) and the Feminist Movement in the 1970s are still unresolved in 21st century America.

First Constraints on Rings in the Pluto System

description: Simple theoretical calculations have suggested that small body impacts onto Pluto's newly discovered small satellites, Nix and Hydra, are capable of generating time-variable rings or dust sheets in the Pluto system. Using HST/ACS data obtained on 2006 February 15 and 2006 March 2, we find no observational evidence for such a ring system and present the first constraints on the present-day I/F and optical depth of a putative ring system. At the 1500-km radial resolution of our search, we place a 3-sigma upper limit on the azimuthally-averaged normal I/F of ring particles of 5.1x10^-7 at a distance of 42,000 km from the Pluto-Charon barycenter, the minimum distance for a dynamically stable ring (Stern et al., 1994; Nagy et al., 2006); 4.4x10^-7 at the orbit of Nix; and 2.5x10^-7 at the orbit of Hydra. For an assumed ring particle albedo of 0.04 (0.38), these I/F limits translate into 3-sigma upper limits on the normal optical depth of macroscopic ring particles of 1.3x10^-5 (1.4x10^-6), 1.1x10^-5 (1.2x10^-6), 6.4x10^-6 (6.7x10^-7), respectively. Were the New Horizons spacecraft to fly through a ring system with optical depth of 1.3x10^-5, it would collide with a significant number of potentially damaging ring particles. We therefore recommend that unless tighter constraints can be obtained, New Horizons cross the putative ring plane within 42,000 km of the Pluto-Charon barycenter, where rings are dynamically unstable. We derive a crude estimate of the lifetime of putative ring paritcles of 900 years.

Redrawing the Boundary: From Carlos Fuentes’s La frontera de cristal (1995) to Rosaura Sánchez and Beatrice Pita’s Lunar Braceros 2125-2148 (2009)*

description: This article traces the workings of the border in Carlos Fuentes’ La frontera de cristal, Alejandro Morales’ The Rag Doll Plagues, Alex Rivera’s film Sleep Dealer, and Rosaura Sánchez and Beatrice Pita’s Lunar Braceros 2125-2140. All the narratives can be considered borderland texts that illustrate the dialogue between literature and issues such as globalization, technology and colonial relations of power. While the border is still a place of detention and interdiction in Fuentes’ novel, it mutates into virtual crossings in The Rag Doll Plagues and Sleep Dealer, to return to barbed wire in Sánchez and Pita’s novella. From the logic of the border as a mechanism that may open or close, the article moves on to address the liminal situation of those who, although situated within the new versions of the nation-state, are considered permanent outsiders. This redrawing of boundaries allows us to revisit traditional categories of distinction such as the inside and the outside, and is evidence of the way colonial models of subjugation boomerang to the present.
