description: Data-driven analysis methods can help to infer physical properties of red giant stars where "gold-standard" asteroseismic data are not available. The study of optical and infrared spectra of red giant stars with data-driven analyses has revealed that differences in oscillation frequencies and their separations are imprinted in said spectra. This makes it possible to confidently differentiate core-helium burning red clump stars (RC) from those that are still on their first ascent of the red giant branch (RGB). We extend these studies to a tenfold larger wavelength range of 0.33 to 2.5 microns with the moderate-resolution VLT/X-shooter spectrograph. Our analysis of 49 stars with asteroseismic data from the K2 mission confirms that CN, CO and CH features are indeed the primary carriers of spectroscopic information on the evolutionary stages of red giant stars. We report 215 informative features for differentiating the RC from the RGB within the range of 0.33 to 2.5 microns. This makes it possible for existing and future spectroscopic surveys to optimize their wavelength regions to deliver both a large variety of elemental abundances and reliable age estimates of luminous red giant stars.

description: The paper describes the phenomenon of multiculturalism at the International Festival of Sacred Music Gaude Mater in Częstochowa. The festival has been running since 1991. It includes a variety of artistic events, most of them sacred music concerts (Gregorian chant, early music, Orthodox, Polish music from all historical periods, and premieres). The festival also promotes the musical culture of Jasna Góra. The special feature of the festival is its multiculturalism involving the presentation of non-Christian sacred music. In the years 1991-2010, the festival featured Jewish, Muslim, Egyptian, and African music. The dialogue between cultures also facilitates connections between high and mass culture. This is accomplished through various combinations of gospel, jazz, pop elements with classical music. In addition, the attempts of dialogue between different cultures furnish a number of non-musical events, such as theatre performance, arts exhibitions, and conferences.

description: The signal transduction cascade operational in the vomeronasal organ (VNO) of the olfactory system detects odorants important for prey localization, mating, and social recognition. While the protein machinery transducing these external cues has been individually well characterized, little attention has been paid to the role of protein-protein interactions among these molecules. Development of an in vitro expression system for the transient receptor potential 2 channel (TRPC2), which establishes the first electrical signal in the pheromone transduction pathway, led to the discovery of two protein partners that couple with the channel in the native VNO. Homer family proteins were expressed in both male and female adult VNO, particularly Homer 1b/c and Homer 3. In addition to this family of scaffolding proteins, the chaperones receptor transporting protein 1 (RTP1) and receptor expression enhancing protein 1 (REEP1) were also expressed. RTP1 was localized broadly across the VNO sensory epithelium, goblet cells, and the soft palate. Both Homer and RTP1 formed protein-protein interactions with TRPC2 in native reciprocal pull-down assays and RTP1 increased surface expression of TRPC2 in in vitro assays. The RTP1-dependent TRPC2 surface expression was paralleled with an increase in ATP-stimulated whole-cell current in an in vitro patch-clamp electrophysiological assay. TRPC2 expression and channel activity is regulated by chaperone- and scaffolding-associated proteins, which could modulate the transduction of chemosignals. The developed in vitro expression system, as described here, will be advantageous for detailed investigations into TRPC2 channel activity and cell signalling, for a channel protein that was traditionally difficult to physiologically assess.

description: The pair-correlation functions for fluid ionic mixtures in arbitrary spatial dimensions are computed in hypernetted chain (HNC) approximation. In the primitive model, all ions are approximated as non-overlapping hyperspheres with Coulomb interactions. Our spectral HNC solver is based on a Fourier-Bessel transform introduced by Talman [J. Comput. Phys., 29, 35 (1978)], with logarithmically spaced computational grids. Numeric efficiency for arbitrary spatial dimensions is a commonly exploited virtue of this transform method. Here, we highlight another advantage of logarithmic grids, consisting in efficient sampling of pair-correlation functions for highly asymmetric ionic mixtures. For three-dimensional fluids, ion size- and charge-ratios larger than one thousand can be treated, corresponding to hitherto computationally not accessed micrometer-sized colloidal spheres in 1-1 electrolyte. Effective colloidal charge numbers are extracted from our primitive model results. For moderately large ion size- and charge-asymmetries, we present Molecular Dynamics simulation results that agree well with the approximate HNC pair correlations.

description: The author argues that music should not be mediated as a scientifically reduced object to amateurs and students, but as a message for the listener. Music is not a kind of strange “thing”, but a “virtually-you”, and looks for a dialogue with everybody who listens to it. Music claims: “I mean you! I’m talking about you! I want to talk to you”! Not only is music sound and structure, but a life lived as a reflection of sounds. It is the shape in which the dialogue with music finds its sustenance. The author examines one of the time-honored musical forms – the rondo – to demonstrate his view. From a historical perspective, the rondo is a round-song, which plays an important role in our daily lives. With its typical contrast between what is already known (chorus) and new elements (couplet), the rondo reflects our different experiences of time: time as a line (time of day) and time as a circle (circle of celebration). This article offers an insight into the theme of live of the author: hermeneutics as the science of understanding, here is the music.

description: The right to vote has been irrefutably established as one of the most treasured and fundamental rights guaranteed to citizens by the United States Constitution, and Wisconsin’s Act 23 (“Act 23”) violates this standard. In May 2011, the Wisconsin legislature passed this act, which mandated that any person attempting to vote in person or via absentee ballot had to present an approved form of government-issued photo identification. In application, Act 23 would fail to satisfy its main goal of preventing voter fraud because, had it not been enjoined in March 2012, the law would not have prevented any of the limited attempts at voter fraud that have already occurred in the state. In the modern era of jurisprudence, the U.S. Supreme Court has determined that this right is so fundamental that any attempt to limit or violate it must be met with an extraordinarily close and careful examination, and any such examination would find Act 23 to be unconstitutional. The process of obtaining a valid form of identification is a great burden for the state’s poor, minority and elderly citizens, and this burden is not met with a necessary and narrowly tailored law sufficient to justify the equal protection injuries inflicted on the voting population. Act 23 also violates the Twenty-Fourth Amendment by not offering a completely free form of identification for indigent citizens, thereby creating a poll tax. Lastly, the Wisconsin Constitution has a complete article on suffrage and on the conditions necessary for changing voting laws, which Act 23 fails to meet, rendering it unconstitutional at both the state and federal levels.

description: In Bloch’s works, the world of different meanings, ideas, and nonmusical contexts is of paramount importance. The composer often uses words as a medium intimately entwined with music. The reason for such an artistic declaration is the array of different events in Bloch’s life: his interest in the organ influenced by his father, his adventures with illustrative music, and the relationship with his wife – the excellent Polish singer – Halina Łukołomska. All these elements are the reason why Bloch’s works are inspired by poetical text, images, associations, and aesthetic sensations. Multicultural aspects in Bloch’s works stem from his contacts with German artists and patrons. These collaborations resulted in many outstanding works written for German artists. Some of his works were inspired by Bloch’s friendship with German painter Ingeborg zu Schleswig-Holstein (Denn Dein Licht Kommt/ Albowiem nadejdzie światłość Twoja; Du sollst nicht töten/ Nie zabijaj!; Empor/ Wzwyż). Three of Bloch’s works: Wordsworth Songs, Die Verscheuchte, Anenaiki were primarily inspired by formal and verbal construction and not as much by foreign cultures.

description: We develop statistical methods within a Bayesian framework to infer the star formation history from photometric surveys of pre-main sequence populations. Our procedures include correcting for biases due to extinction in magnitude-limited surveys, and using distributions from subsets of stars with individual extinction measurements. We also make modest corrections for unresolved binaries. We apply our methods to samples of populations with Gaia photometry in the Orion A molecular cloud. Using two well-established sets of evolutionary tracks, we find that, although our sample is incomplete at youngest ages due to extinction, star formation has proceeded in Orion A at a relatively constant rate between ages of about 0.3 and 5 Myr, in contrast to other studies suggesting multiple epochs of star formation. Similar results are obtained for a set of tracks that attempt to take the effects of strong magnetic fields into account. We also find no evidence for a well-constrained "birthline" that would result from low-mass stars appearing first along the deuterium-burning main sequence, especially using the magnetic evolutionary tracks. While our methods have been developed to deal with Gaia data, they may be useful for analyzing other photometric surveys of star-forming regions.

description: Fast polarization switching of light sources is required over a wide spectral range to investigate the symmetry of matter. In this Letter, we report the first experimental demonstration of the crossed-planar undulator technique at a seeded free-electron laser, which holds great promise for the full control and fast switching of the polarization of short-wavelength radiation. In the experiment, the polarization state of the coherent radiation at the 2nd harmonic of the seed laser is switched successfully. The experiment results confirm the theory, and pave the way for applying the crossed-planar undulator technique for the seeded X-ray free electron lasers.

description: We address the issue of extending thermodynamics to nonequilibrium steady states. Using driven stochastic lattice gases, we ask whether consistent definitions of an effective chemical potential mu, and an effective temperature T_e, are possible. mu and T_e are determined via coexistence, i.e., zero flux of particles and energy between the driven system and a reservoir. In the lattice gas with nearest-neighbor exclusion, temperature is not relevant, and we find that the effective chemical potential, a function of density and drive strength, satisfies the zeroth law, and correctly predicts the densities of coexisting systems. In the Katz-Lebowitz-Spohn driven lattice gas both mu and T_e need to be defined. We show analytically that in this case the zeroth law is violated for Metropolis exchange rates, and determine the size of the violations numerically. The zeroth law appears to be violated for generic exchange rates. Remarkably, the system-reservoir coupling proposed by Sasa and Tasaki [J. Stat. Phys. 125, 125 (2006)], is free of inconsistencies, and the zeroth law holds. This is because the rate depends only on the state of the donor system, and is independent of that of the acceptor.

description: For a simple $n$-polytope $P$, a quasitoric manifold over $P$ is a $2n$-dimensional smooth manifold with a locally standard action of the $n$-dimensional torus for which the orbit space is identified with $P$. This paper shows the topological classification of quasitoric manifolds over the dual cyclic polytope $C^n(m)^*$, when $n>3$ or $m-n=3$. Besides, we classify small covers, the "real version" of quasitoric manifolds, over all dual cyclic polytopes.

description: The extent of student underachievement in subSaharan Africa is confirmed by international student assessments such as The Trends in International Mathematics and Science Study (TIMSS) and Progress in International Reading Literacy Study (PIRLS). TIMSS measures trends in mathematics and science achievement at fourth and eighth grades while PIRLS is a comprehensive assessment of fourth grade students' reading literacy achievement. TIMSS 2015 data on Grade 8 students shows that in the participating sub-Saharan African countries (Botswana, Ghana, South Africa), between 68% and about 90% of students failed to reach the low benchmark in mathematics and science. PIRLS 2016 data suggests 78% of South African students could not read for comprehension. Among the factors that were identified to explain the poor learning achievement in the region are, poor mastery of the curriculum, rigid teaching practices, lack of textbooks and, most importantly, teaching materials in a language not well understood by the students, as well as low proficiency in the language of instruction (vital for effective learning). This article explores the pivotal role translanguaging plays in epistemic access, recommending teachers to view students’ linguistic repertoire as a teaching/learning resource and not a hindrance.

description: In Tanzania, less than a third of HIV infected children estimated to be in need of antiretroviral therapy (ART) are receiving it. In this setting where other infections and malnutrition mimic signs and symptoms of AIDS, early diagnosis of HIV among HIV-exposed infants without specialized virologic testing can be a complex process. We aimed to introduce an Early Infant Diagnosis (EID) pilot program using HIV DNA Polymerase Chain Reaction (PCR) testing with the intent of making EID nationally available based on lessons learned in the first 6 months of implementation. In September 2006, a molecular biology laboratory at Bugando Medical Center was established in order to perform HIV DNA PCR testing using Dried Blood Spots (DBS). Ninety-six health workers from 4 health facilities were trained in the identification and care of HIV-exposed infants, HIV testing algorithms and collection of DBS samples. Paper-based tracking systems for monitoring the program that fed into a simple electronic database were introduced at the sites and in the laboratory. Time from birth to first HIV DNA PCR testing and to receipt of test results were assessed using Kaplan-Meier curves. From October 2006 to March 2007, 510 HIV-exposed infants were identified from the 4 health facilities. Of these, 441(87%) infants had an HIV DNA PCR test at a median age of 4 months (IQR 1 to 8 months) and 75(17%) were PCR positive. Parents/guardians for a total of 242(55%) HIV-exposed infants returned to receive PCR test results, including 51/75 (68%) of those PCR positive, 187/361 (52%) of the PCR negative, and 4/5 (80%) of those with indeterminate PCR results. The median time between blood draw for PCR testing and receipt of test results by the parent or guardian was 5 weeks (range <1 week to 14 weeks) among children who tested PCR positive and 10 weeks (range <1 week to 21 weeks) for those that tested PCR negative. The EID pilot program successfully introduced systems for identification of HIV-exposed infants. There was a high response as hundreds of HIV-exposed infants were registered and tested in a 6 month period. Challenges included the large proportion of parents not returning for PCR test results. Experience from the pilot phase has informed the national roll-out of the EID program currently underway in Tanzania.

description: Dynamic mode decomposition (DMD) represents an effective means for capturing the essential features of numerically or experimentally generated flow fields. In order to achieve a desirable tradeoff between the quality of approximation and the number of modes that are used to approximate the given fields, we develop a sparsity-promoting variant of the standard DMD algorithm. In our method, sparsity is induced by regularizing the least-squares deviation between the matrix of snapshots and the linear combination of DMD modes with an additional term that penalizes the $\ell_1$-norm of the vector of DMD amplitudes. The globally optimal solution of the resulting regularized convex optimization problem is computed using the alternating direction method of multipliers, an algorithm well-suited for large problems. Several examples of flow fields resulting from numerical simulations and physical experiments are used to illustrate the effectiveness of the developed method.

mRNA export

description: The nuclear pore complex (NPC) is one of the largest and most complex protein assemblies in eukaryotic cells, and it facilitates and regulates the bidirectional transfer of molecules between the nucleus and cytoplasm. One of the essential functions of the NPC is to directly regulate the export of mature mRNAs, but the mechanism is not well understood, especially in humans. Export of mRNA is completed at the cytoplasmic side of the NPC, where ATPase activity of the DEAD-box helicase DDX19 is specifically activated by the NPC components Gle1, Nup42, and Nup214. The mRNA export factor Gle1 is an essential nucleoporin, and Gle1 dysfunction has been linked to human diseases. We show that the Gle1-Nup42 interaction is highly conserved with X-ray crystal structures and that the thermostability of Gle1 is highly dependent on Nup42. We also find that disease-linked mutants of Gle1 show strongly altered thermostability. Analysis of DDX19 steady-state ATPase activity reveals a novel mode of activation by Gle1 in humans. Structural studies of DDX19 complement the biochemical characterization of DDX19, and we have proposed a working model for the DDX19 catalytic cycle. An outstanding question remains in this model, as the details of DDX19-mediated removal of the export factor NXF1-NXT1 from mRNA are unknown. We describe a method for large-scale purification of retroviral constitutive transport element (CTE) RNA, which hijacks NXF1-NXT1 to be exported through the NPC, for X-ray crystallographic studies of a NXF1-NXT1-CTE complex. Together, these results provide a detailed structural and functional description of mRNA export regulation by the NPC and a framework for understanding the molecular basis of human disease linked to Gle1 and viral proliferation.

description: We numerically compute eigenvalues of the non-self-adjoint Zakharov--Shabat problem in the semiclassical regime. In particular, we compute the eigenvalues for a Gaussian potential and compare the results to the corresponding (formal) WKB approximations used in the approach to the semiclassical or zero-dispersion limit of the focusing nonlinear Schroedinger equation via semiclassical soliton ensembles. This numerical experiment, taken together with recent numerical experiments [17,18], speaks directly to the viability of this approach; in particular, our experiment suggests a value for the rate of convergence of the WKB eigenvalues to the true eigenvalues in the semiclassical limit. This information provides some hint as to how these approximations might be rigorously incorporated into the asymptotic analysis of the singular limit for the associated nonlinear partial differential equation.

Revisiting the orbital motion of WR 138

description: The optical spectrum of WR 138 exhibits emission lines typical of a WN6o star and absorption lines from a rapidly-rotating OB star. Using a large set of spectroscopic data, we establish a new orbital solution of the WN6o star based on the radial velocities of highly-ionized nitrogen lines. We show that the WN6o star moves on a 4.3 yr orbit with a comparatively low eccentricity of 0.16. The radial velocities of the OB star display considerable scatter. Our best estimates of the velocities of He I absorption lines result in a mass-ratio of $m_{\rm WN6o}/m_{\rm OB} = 0.53 \pm 0.09$. We disentangle the spectra of the two stars and derive a projected rotational velocity of $v\,\sin{i} = 350 \pm 10$ km s$^{-1}$ for the OB star. Our best orbital parameters, combined with the Gaia parallax of WR 138, are at odds with a previous interferometric detection of the companion, suggesting that there is either a bias in this detection or that WR 138 is actually a triple system.

Thinking about Edward Said: Pages from a Memoir

description: When I had contracted with the University of Massachusetts Press—in 1967 or 1968—to translate De la grammatologie, my editor sent me a copy of Edward Said’s “Abecedarium culturae: Structuralism, Absence,Writing” that had just appeared in TriQuarterly and was later included as a chapter
in Beginnings. It must have been 1971. Well, I read the piece. I had ordered Derrida off a catalogue, on impulse, not knowing his name, or anything about the French scene. It was a sort of self-help project, to which I still subscribe, shamefacedly. I have no general education, whereas Edward’s piece seemed to be incredibly knowledgeable in just that way. I read the piece carefully, made notes in the margin, and filed it.
1971. I was to meet Derrida for the first time later that year. I am looking at my notes on Edward’s article. Remember, I didn’t know him or know of him either. I was not under his spell, as I later would be, like anyone who met him. I was only a dogged translator learning on the job, a patient and transfixed reader. I noticed this American’s (nothing in the piece gave any other clue) impatient mistranslations. (It was much later that I would come to realize that this charming impatience was part of his signature.)
Perceptional and Socio-Demographic Factors Associated with Household Drinking Water Management Strategies in Rural Puerto Rico

description: Identifying which factors influence household water management can help policy makers target interventions to improve drinking water quality for communities that may not receive adequate water quality at the tap. We assessed which perceptional and socio-demographic factors are associated with household drinking water management strategies in rural Puerto Rico. Specifically, we examined which factors were associated with household decisions to boil or filter tap water before drinking, or to obtain drinking water from multiple sources. We find that households differ in their management strategies depending on the institution that distributes water (i.e. government PRASA vs community-managed non-PRASA), perceptions of institutional efficacy, and perceptions of water quality. Specifically, households in PRASA communities are more likely to boil and filter their tap water due to perceptions of low water quality. Households in non-PRASA communities are more likely to procure water from multiple sources due to perceptions of institutional inefficacy. Based on informal discussions with community members, we suggest that water quality may be improved if PRASA systems improve the taste and odor of tap water, possibly by allowing for dechlorination prior to distribution, and if non-PRASA systems reduce the turbidity of water at the tap, possibly by increasing the degree of chlorination and filtering prior to distribution. Future studies should examine objective water quality standards to identify whether current management strategies are effective at improving water quality prior to consumption.
Perturbative expansion of the plaquette to ${\cal O}(α^{35})$ in four-dimensional SU(3) gauge theory

description: Using numerical stochastic perturbation theory, we determine the first 35 infinite volume coefficients of the perturbative expansion in powers of the strong coupling constant $α$ of the plaquette in SU(3) gluodynamics. These coefficients are obtained in lattice regularization with the standard Wilson gauge action. The on-set of the dominance of the dimension four renormalon associated to the gluon condensate is clearly observed. We determine the normalization of the corresponding singularity in the Borel plane and convert this into the $\overline{\mathrm{MS}}$ scheme. We also comment on the impact of the renormalon on non-perturbative determinations of the gluon condensate.

THE PASSACAGLIA – A PRIMER FOR TEACHING BAROQUE IMPROVISATION
Creators: name: Terefenko, Dariusz
Publisher: name: ARS INTER CULTURAS
Year: 2018

description: During the lifetime of Bach such disciplines as harmony and thoroughbass were realized directly at the keyboard by the student, providing a solid foundation for later and more elaborate improvisatory skills – skills which were mandatory for all clavier players of that period. Unfortunately, the great majority of today’s Baroque counterpoint classes rely on the more academic process of committing notes to paper, thereby subjugating aural and performance skills. In this article, I propose amending music theory curricula with topics in baroque improvisation. To that end I will employ one of the most accessible variation forms from common practice music: the passacaglia.

description: The chemical equilibrium distribution of 69 elements between gas and melt is modeled for bulk silicate Earth (BSE) material from 1000 - 4500 K and 1e-6 to 100 bar. The BSE melt is modeled as a non-ideal solution and the effects of different activity coefficients and ideal solution are studied. Results include 50% condensation temperatures, major gases of each element, and oxygen fugacity (fO2) of dry and wet BSE material. The dry BSE model excludes H, C, N, F, Cl, Br, I, S, Se, Te. The wet BSE model includes H and the other volatiles. Key conclusions are much higher condensation temperatures in silicate vapor than in solar composition gas at the same total P, a different condensation sequence in silicate vapor than in solar composition gas, good agreement between different activity coefficient models except for the alkalis, agreement, where overlap exists, with prior published work, condensation of Re, Mo, W, Ru, Os oxides instead of metals, a stability field for Ni-rich metal as reported by Lock et al. (2018), agreement between ideal solution (from this work and from Lock et al. 2018) and real solution condensation temperatures for elements with minor deviations from ideality in the oxide melt, similar 50% condensation temperatures, within a few degrees, in the dry and wet BSE models for the major elements Al, Ca, Fe, Mg, Si, and the minor elements Co, Cr, Li, Mn, Ti, V, and much lower 50 percent condensation temperatures for elements such as B, Cu, K, Na, Pb, Rb, which form halide, hydroxide, sulfide, selenide, telluride and oxyhalide gases. The latter results are preliminary because the poorly known solubilities and activities of volatile elements in silicate melts must be considered for the correct equilibrium distribution, condensation temperatures and mass balance of F, Cl, Br, I, H, S, Se and Te bearing species between melt and vapor (abridged).

CYGAŃSCY MUZYCY W EUROPIE – SZKIC HISTORYCZNY

Publisher: name: ARS INTER CULTURAS
Year: 2018

description: The article begins by explaining the origins of Gypsies with an emphasis on the linguistic and anthropological theories tracing Indian decadency of Gypsies. Drawing from historical documents as well as poetry and other sources, the authors presents the association of Gypsies with music. The aritcle offers an explanation why Gypsies were often engaged in music making for money and linked with medieval travelling troupes performing entertainment shows. The article also highlights the origins of stereotypes associated with Gypsies. The author pays special attention to the forming of the image of a Hungarian Gypsy claiming that the widely spread vision of a Gypsy musician is stereotypically associated with Gypsy musicians from Habsburg Monarchy, playing in so-called Zigeunerkapellen. In addition, the musical traditions of Spanish Gypsies are presented, since the author believes that the Gypsy-musician stereotype is closely linked with the fate of Gypsies in Europe.
