description: Research for possible biosignature gases on habitable exoplanet atmosphere is accelerating. We add isoprene, C5H8, to the roster of biosignature gases. We found that formation of isoprene geochemical formation is highly thermodynamically disfavored and has no known abiotic false positives. The isoprene production rate on Earth rivals that of methane (~ 500 Tg yr-1). On Earth, isoprene is rapidly destroyed by oxygen-containing radicals, but its production is ubiquitous to a diverse array of evolutionarily distant organisms, from bacteria to plants and animals-few, if any at all, volatile secondary metabolite has a larger evolutionary reach. While non-photochemical sinks of isoprene may exist, the destruction of isoprene in an anoxic atmosphere is mainly driven by photochemistry. Motivated by the concept that isoprene might accumulate in anoxic environments, we model the photochemistry and spectroscopic detection of isoprene in habitable temperature, rocky exoplanet anoxic atmospheres with a variety of atmosphere compositions under different host star UV fluxes. Limited by an assumed 10 ppm instrument noise floor, habitable atmosphere characterization using JWST is only achievable with transit signal similar or larger than that for a super-Earth sized exoplanet transiting an M dwarf star with an H2-dominated atmosphere. Unfortunately, isoprene cannot accumulate to detectable abundance without entering a run-away phase, which occurs at a very high production rate, ~ 100 times Earth's production rate. In this run-away scenario isoprene will accumulate to > 100 ppm and its spectral features are detectable with ~ 20 JWST transits. One caveat is that some spectral features are hard to be distinguished from that of methane. Despite these challenges, isoprene is worth adding to the menu of potential biosignature gases.

Review of Alexander Rehding. 2003. Hugo Riemann and the Birth of Modern Musical Thought. New York and Cambridge: Cambridge University Press
Creators: name: Kim, Youn
Publisher: name: Current Musicology
Year: 2003

description: For a long time, historical studies of the sciences adopted a perspective variously known by the names presentist, teleological, essentialist, or Whiggish. Although these expressions carry slightly different meanings, we may roughly characterize this approach as an attempt to read the past in terms of present concerns; past scientific theories that had proven to be “wrong” and displaced by “right” theories are regarded as inferior fringe elements in the history of modern sciences. This approach is, of course, now passe. Most historical studies of the sciences, especially since the publication of Thomas Kuhn’s influential work, are not afraid to explore neglected scientific concepts and theories, and tend to rely heavily on the conceptual and cultural frameworks derived from areas other than science itself. I find it appropriate, therefore, to begin the review of Alexander Rehding’s Hugo Riemann and the Birth of Modern Musical Thought with a discussion of the historiography of science. First, the union of history and science-as well as that of history and music theory-presents some problems. Although it may be naIve, it is undeniable that most people still feel odd about the joining of science and history: the former is forward-looking and concerned with nature, whereas the latter is retrospective and deals with humanity. Likewise, the conjunction of music theory and history raises some conceptual difficulties. In Thomas Christensen’s words, music theory is a “subject that notoriously resists its own history” (2002: 1). Second, the parallelism between science and music theory is significant in studies of late nineteenth-century music theory, particularly in the study of Hugo Riemann’s ideas. Given that many of these theories aspired to scientific grounding, we may parallel historical approaches to the music theory of this period with historiographies of science. In attempting to discuss the shift in perspective in the realm of music theory’s history, we find Riemann’s notion of “harmonic dualism” the best case in point. Riemann believed that “minor triads are symmetrically opposed to major triads and work upsidedown” (Rehding 2003:7), an idea that was quickly discredited by many later generation theorists.

description: We have calculated the finite-frequency current noise of a superconductor-ferromagnet quantum point contact (SF QPC). This signal is qualitatively affected by the spin-dependence of interfacial phase shifts (SDIPS) acquired by electrons upon reflection on the QPC. For a weakly transparent QPC, noise steps appear at frequencies or voltages determined directly by the SDIPS. These steps can occur at experimentally accessible temperatures and frequencies. Finite frequency noise is thus a promising tool to characterize the scattering properties of a SF QPC.

description: We introduce a model to describe the wide shear zones observed in modified Couette cell experiments with granular material. The model is a generalization of the recently proposed approach based on a variational principle. The instantaneous shear band is identified with the surface that minimizes the dissipation in a random potential that is biased by the local velocity difference and pressure. The apparent shear zone is the ensemble average of the instantaneous shear bands. The numerical simulation of this model matches excellently with experiments and has measurable predictions.

description: The Association for the Advancement of Creative Musicians (AACM), which recently celebrated its 50th birthday, is certainly one of the most important musical movements of the twentieth and twenty-first centuries. This much we know. This thick and dense book, written by French an-thropologist and musical theorist Alexandre Pierrepont over a period of almost twenty years, demonstrates that, on top of inventing new ways to make music, the members of the AACM also invented better ways to make a society. Subtitled A Game-Play of Musical Society, it offers a profound and joyous analysis of the many strata simultaneously developed in Chicago beginning in 1965 by African American musicians who had no alternative but to invent new social relations in order to survive economically and thrive artistically as creators, in a country doubly biased against African Americans and against artistic experimentations and lifestyles.

description: This article discusses the physical and kinematical characteristics of planetary nebulae accompanying PG1159 central stars. The study is based on the parallax and proper motion measurements recently offered by Gaia space mission. Two approaches were used to investigate the kinematical properties of the sample. The results revealed that most of the studied nebulae arise from progenitor stars of mass range; $0.9-1.75$\,M$_{\odot}$. Furthermore, they tend to live within the Galactic thick-disk and moving with an average peculiar velocity of $61.7\pm19.2$\,km\,s$^{-1}$ at a mean vertical height of $469\pm79$ pc. The locations of the PG1159 stars on the H-R diagram indicate that they have an average final stellar mass and evolutionary age of $0.58\pm0.08$\,M$_{\odot}$ and $25.5\pm5.3 \rm{x}10^3$ yr, respectively. We found a good agreement between the mean evolutionary age of the PG1159 stars and the mean dynamical age of their companion planetary nebulae ($28.0\pm6.4 \rm{x}10^3$ yr).

Anisotropic Thermal Conduction in Supernova Remnants: Relevance to Hot Gas Filling Factors in the Magnetized ISM

description: We explore the importance of anisotropic thermal conduction in the evolution of supernova remnants via numerical simulations. The mean temperature of the bubble of hot gas is decreased by a factor of ~3 compared to simulations without thermal conduction, together with an increase in the mean density of hot gas by a similar factor. Thus, thermal conduction greatly reduces the volume of hot gas produced over the life of the remnant. This underscores the importance of thermal conduction in estimating the hot gas filling fraction and emissivities in high-stage ions in Galactic and proto-galactic ISMs.

Varèse in Vitro: On Attention, Aurality, and the Laboratory
Creators: name: Steege, Benjamin
Publisher: name: Current Musicology
Year: 2003

description: In his 1936 lecture on “New Instruments and New Music,” Edgard Varese insisted “There should be at least one laboratory in the world where the fundamental facts of music could be investigated under conditions reasonably conducive to success. The interest in music is so widespread and intense, its appeal so intimate and poignant, and its significance for mankind so potent and profound, that it becomes unwise not to devote some portion of the enormous outlay for music to research in its fundamental questions.” (1967:197) Though Varese was quoting this entire paragraph from a 1928 popular-science monograph by John Redfield, former physics lecturer at Columbia University, the composer made the sentiment and argument very much his own in other writings and interviews from the period. Yet some uncertainties remain as to the laboratory’s value for Varese. Did his vision of music as an “art -science” stem simply from infatuation with scientific authority? What were the specific “conditions reasonably conducive to” a laboratory’s success? In what would this “success” consist?

description: This present work is a qualitative research carried on through inferences that rise from a structural system of discourse analysis in film, with the main objective of finding the elements of semiotic discourse within the 2016 film Arrival and analyze the way in which these elements show linguistic determinism as proposed in the Sapir-Whorf Hypothesis. This was to be achieved through the use of Lauro Zavala’s model on film analysis (2003). Research was conducted in the fields of linguistics, semiotics and film analysis with the goal to benefit general audiences, film enthusiasts, linguistic professionals, and Film, Linguistics and English students. At the same time, the methodology used for this research can help audiences when they watch films similar to Arrival. Zavala’s method is a model of film analysis that looks to contribute to the systematization of ideas and interpretation of people who watch a movie; this, done through its 12-point system that can be used in its entirety, out of order or partially. This research is, almost in its entirety, linked to Linguistic Determinism, which is one of the most important and influential linguistics theories of the Twentieth Century. It can be concluded that Zavala’s method helped to identify linguistic determinism as a worldview in practice on the film, extreme the scenario for its practice, the editing of the film itself as a parallel to linguistic determinism, and how learning the alien language, Heptapod B, is presented as an advantage for humanity.
Review of Thomas Goldsmith, ed. 2004. The Bluegrass Reader. Urbana: University of Illinois Press

description: In a world of increasingly uncertain American identity, it is hardly surprising that an interest in bluegrass music, so tied to notions of white America, should be enjoying a revival. Editor Thomas Goldsmith’s The Bluegrass Reader is the latest addition to a small canon of historical literature that is beginning to coalesce in this environment. Rather than aim for historical definitiveness, as was the case with Tom Ewing’s Bill Monroe Reader (2000), Goldsmith widens his scope to include many forms of documentation including promotional materials, record and CD liner notes, interviews, academic articles, newspaper and magazine articles, program notes, speech transcripts- even a record review parody. The result is a subjective, impressionistic collage of material that breaks little new theoretical ground, but assembles a great deal of essential historical information, representing many facets of the bluegrass universe. For this effort, Goldsmith was recently awarded the International Bluegrass Music Association’s 2004 award for Print Media Personality of the Year.

Car son toute oeuvre se place à deçà des nécessités de son époque. (Boulez 1952d:119) * * * The statement has since come to caricature our experience of high musical modernism. Its uncompromising tone has ensured the author's place in a narrowly defined historiography that continues to see him as the defender of a universal ("toutmusicien"; "son toute oeuvre") and abstract ("la langage dodecaphonique") musical system. The author, of course, was the then still relatively unknown Pierre Boulez, writing here in his early article "Eventuellement ... ".

BTZ Black Hole with Higher Derivatives, the Second Law of Thermodynamics, and Statistical Entropy: A New Proposal

description: I consider the thermodynamics of the BTZ black hole in the presence of the higher curvature and gravitational Chern-Simons terms, and its statistical entropy. I propose a new thermodynamical entropy, which being {\it non-negative} manifestly, such as the second law, as well as the first law, of thermodynamics is satisfied. I show that the new \therl entropy agrees perfectly with the statistical entropy for $all$ the values of the conformal factor of the higher curvature terms and the coupling constant of the gravitational Chern-Simons term, in contrast to some disagreements in the literatures. The agreement with both the higher curvature and gravitational Chern-Simons terms is possible because of an appropriate balancing of them, though it is not a trivial matter because of a conflict in the appropriate Hilbert space for a well-defined conformal field theory for each term.

Characterization of the 16 kDalton heat shock proteins of Caenorhabditis elegans
Creators: name: Hockertz, Michael Karl
Publisher: name: University of British Columbia
Year: 2010

description: The 16 kDa heat shock proteins of C. elegans have been partially purified and characterized using antipeptide antibodies and standard chromatographic techniques. Based upon the sequences of the previously isolated hsp16 genes, peptides were synthesized against which polyclonal antibodies were produced in rabbits. The antibodies were used to detect fractionated hspl6 by the western blot technique and to purify hsp16 by affinity chromatography. The specificity of the anti-peptide antibodies indicated that the four hsp16 genes may encoded both 16 kDa and the 18 kDa polypeptides. The latter were previously thought to be derived from distinct genes. Two-dimensional gel electrophoresis showed that the 16 kDa hsps exist in multiple isoforms, probably due to their posttranslational modification. Hsp16 was purified by affinity chromatography with immobilized antibody to a C-terminal 36 residue peptide of hsp16-2. The hspl6s did not bind to the antibody in a low salt buffer, but did so in the presence 4M urea. Hsp16 was fractionated by hydroxylapatite and gel exclusion chromatography and shown to exist as a large reasonably uniform complex of 460±55 kDa.
Getting Information on |U_{e3}|^2 from Neutrino-less Double Beta Decay

description: We consider the possibility to gain information on the lepton mixing matrix element |U_{e3}| from an improved experimental limit on the effective neutrino mass governing neutrino-less double beta decay. We show that typically a lower limit on |U_{e3}| can be set. Furthermore, we give the values of the sum of neutrino masses and |U_{e3}| which are allowed and forbidden by an experimental upper limit on the effective mass. Alternative explanations for neutrino-less double beta decay or Dirac neutrinos would be required if future measurements showed that the values lie in the respective regions. Moreover, we argue that a measurement of |U_{e3}| from neutrino-less double beta decay is very difficult due to the expected errors on the effective mass and the oscillation parameters.

Beyond the Beethoven Model: Sentence Types and Limits
Creators: name: Bailey Shea, Matthew
Publisher: name: Current Musicology
Year: 2004

description: It is quite likely that no other form in the history of Western music theory has been so strongly associated with a single musical example as the sentence. Most forms are not defined by a single locus classicus – no one piece serves as the ultimate paradigm of sonata form, no single phrase represents the virtual embodiment of the period. When it comes to the sentence, however, one example is consistently privileged above all others: Beethoven’s Piano Sonata in F Minor, op. 2, no.1, first movement, bars 1-8 (ex. I). The most obvious reason that this example is so favored is that Arnold Schoenberg himself used it as the primary exemplar of the form.! (Schoenberg, of course, “discovered” the sentence.) Since then, nearly every theorist who has written about the sentence has mentioned the Beethoven theme as a model example.2 It would be inaccurate, however, to assume that theorists continue to emphasize this example simply because Schoenberg used it first. After all, the theme does provide an excellent example of many standard sentence features. Bars 1-4 contain a common tonic-dominant alternation-what William Caplin refers to as “statement-response repetition” (1998:37-39). The continuation includes typical features such as motivic fragmentation and acceleration of harmonic rhythm, and the sentence concludes with a conventional half-cadence. The overall metric grouping, moreover, is the usual 2+2+4, and the continuation contains a typical embedded grouping of 1 + 1 + 2. Yet when we consider how theorists have written about this theme, it becomes clear that the example is not privileged because of these generic qualities alone.

description: The Swiss scenery artist Adolphe Appia, born in Geneva in 1862, is thought by many in the theatrical community to be a forefather of modern theater, particularly for his radical ideas concerning stage lighting. His artistic in-terest in stage production was motivated and inspired early on by his pas-sion for Wagner's music dramas; evidence for this is apparent in his first published writing, La mise en scène du drame wagnérien of 1895, which in-cludes notes for a hypothetical production of Wagner's Ring of the Nibelungen. Around the same time, Appia wrote scenarios for productions of Die Meistersinger von Nurnberg and Parsifal.

description: LoRa wireless technology is an increasingly prominent solution for massive connectivity and the Internet of Things. Stochastic geometry and numerical analysis of LoRa networks usually consider uniform end-device deployments. Real deployments however will often be non-uniform, for example due to mobility. This letter mathematically investigates how non-uniform deployments affect network coverage and suggest optimal deployment strategies and uplink random access transmission schemes. We find that concave deployments of LoRa end-devices with a sub-linear spread of random access inter-transmission times provide optimal network coverage performance.

We verify an effective form of the Bogomolov Conjecture for all curves of genus at most 4 defined over a function field of characteristic zero. We recover the known result for genus 2 curves and in many cases improve upon the known bound for genus 3 curves. For many curves of genus 4 with bad reduction, the conjecture was previously unproved.

The effect of ingested NACL on body temperature in two avian species : the domestic fowl and the glaucous-winged gull
Creators: name: Kojwang, David Ogweno
Publisher: name: University of British Columbia
Year: 2010

description: The relative effects of ingested sodium chloride (NaCl) on body temperature were examined in two avian species; the domestic fowl (Gallus domesticus), a terrestrial bird which excretes NaCl renally, and the Glaucous-winged gull (Larus qlaucescens), a marine bird which excretes NaCl both renally and extrarenally. Plasma sodium ([Na⁺]pl), potassium ([K⁺]pl), chloride ([Cl⁻]pl, ionized ([Ca²⁺]pl) and total calcium ([Ca]pl) concentrations, plasma osmolality (Osmolpl), body temperature, evaporative water loss (EWL), total body water (TBW), respiratory frequency (f), minute ventilation (VE) , and panting thresholds were determined in roosters and gulls exposed to increasing dietary NaCl levels. High dietary NaCl significantly raised gull resting body temperature (40.4°C ± 0 . 4°C) to 41. 0°C ± 0 .5°C (P<0.05) but did not alter rooster body temperature (41.0°C ± 0.2°C) significantly. [Na⁺]pl increased by 5.4% (P<0.01) in gulls and by 3.7% (P<0.01) in roosters, and was correlated with body temperature in gulls (r = 0.497, n = 25) . . [Ca²⁺]pl increased (roosters, 5.5%, P<0.01; gulls, 11.8%, P<0.01) when [Na⁺]pl was high. Plasma sodium to calcium ratios were not altered and were unrelated to body temperature in both species. High dietary NaCl elevated the internal threshold for panting in roosters from 41.95 ± 0.41°C to 42.35 ±0.3 6°C (P<0.05), and the increase was associated with an increase in Osmolpl (303.6 ± 4.0 mosmol/kg to 319.5 ± 4.3 mosmol/kg, P<0.01). In gulls Osmolpl did not increase, neither did panting threshold. Under thermal stress, body temperature rose more rapidly in both roosters and gulls on high salt diets. VE, f, and weight-specific EWL at 30°C, were unaffected in both species by high salt intake. TBW was not related to resting body temperature and did not change significantly with high NaCl intake in either species. It is concluded that resting body temperature is elevated by increased [Na⁺]pl in concentration-dependent fashion rather than a raised Na : Ca ratio in birds with and without salt glands. [Ca²⁺]pl is elevated when [Na⁺]pl is high. The additional Ca²⁺ probably originate from a source other than the bound fraction in plasma; possibly from the intracellular Ca²⁺ pool. The ability of a bird to maintain a stable panting threshold is related to its ability to maintain a stable Osmolpl. EWL, VE, and f are unaffected by NaCl intake unless severe heat stress is imposed.

A View From Death: Ariadne auf Naxos as Failed Totality
Creators: name: Jenkins, Chadwick
Publisher: name: Current Musicology
Year: 2004

description: Originating as a divertissement in Hugo von Hofmannsthal’s adaptation of Moliere’s Ie Bourgeois Gentilhomme, Ariadne aufNaxos stemmed from the poet’s attempt to create a work wherein “the buffo element … is throughout interwoven with the heroic.” As he explained it to his collaborator Richard Strauss, the poet saw in this synthesis of opera seria and commedia dell’ arte elements a “new genre which to all appearances reaches back to a much earlier one, just as all development goes in cycles” (Strauss and Hofmannsthal 1961:76). Embedded in Gentilhomme, the work reached back towards the divertissements familiar in the comedie-ballets of Moliere’s time while simultaneously looking forward to a proto-postmodern aesthetic. The question that has bedeviled numerous commentators has been whether or not this synthesis is successful (and concomitantly, what constitutes a success in this case). The opera’s conclusion has given rise to the most serious contentions (Forsyth 1982:194-203). On the one hand, those who identify the opera with the postmodern tend to see the synthesis as successful-a success predicated upon its perceived lack of cohesion, its tendency towards the fragmentary, the incommensurable. On the other hand, critics such as Karen Forsyth, concentrating on the historicism of the work, condemn it as a failure. Forsyth, in particular, feels that the opera fails owing to Hofmannsthal’s inability to reconcile his reversion to lyric drama with the divertissement structure of the original conception (1982:56-61). However, such condemnation fails to consider the opera within the larger context of Hofmannsthal’s increasing concern with the ethicality of his aesthetic project.

description: For electromagnetic field theories, canonical energy-momentum conservation laws can be derived from the underpinning spacetime translation symmetry according to the Noether procedure. However, the canonical Energy-Momentum Tensors (EMTs) are neither symmetric nor gauge-symmetric (gauge invariant). The Belinfante-Rosenfeld (BR) method is a well-known procedure to symmetrize the EMTs, which also renders them gauge symmetric for first-order field theories. High-order electromagnetic field theories appear in the study of gyrokinetic systems for magnetized plasmas and the Podolsky system for the radiation reaction of classical charged particles. For these high-order field theories, gauge-symmetric EMTs are not necessarily symmetric and vice versa. In the present study, we develop a new gauge-symmetrization method for EMTs in high-order electromagnetic field theories. The Noether procedure is carried out using the Faraday tensor F, instead of the 4-potential A, to derive a canonical EMT T_N. We show that the gauge-dependent part of T_N can be removed using the displacement-potential tensor \mathcal{F}=\mathcal{D}*A/4π, where \mathcal{D} is the anti-symmetric electric displacement tensor. This method gauge-symmetrize the EMT without necessarily making it symmetric, which is adequate for applications not involving general relativity. For first-order electromagnetic field theories, such as the standard Maxwell system, \mathcal{F} reduces to the familiar BR super-potential \mathcal{S}, and the method developed can be used as a simpler procedure to calculate \mathcal{S} without employing the angular momentum tensor in 4D spacetime. When the electromagnetic system is coupled to classical charged particles, the gauge-symmetrization method for EMTs is shown to be effective as well.
Using probate data to determine historical male occupational structures
Creators: name: Keibek, Sebastiaan

description: Leigh Shaw-Taylor and Sir E.A. Wrigley recently published new estimates for the male occupational structure of England and Wales. Their pre-census figures are based on parish register data, but before Rose's Act of 1812, parish registers offer occupational information only in a sample of parishes, and are virtually silent about employments before 1690. This paper examines how the gaps in the parish register data can be filled using a data source which offer more universal coverage and goes back much further in time: probate records. It demonstrates how an, at first sight, critical deficiency of probate data, namely their severe bias towards capital-intensive and/or relatively well-paying occupations, can be overcome by using parish register data for calibration.
Review of Eidsheim, Nina Sun. 2015. Sensing Sound: Singing and Lis-tening as Vibrational Practice.
Creators: name: Vágnerová, Lucie
Publisher: name: Current Musicology

description: One challenge of writing about music has often been summed up with the question “where is the music?”The asker gets at the impossibility of isolat-ing the musical text to be studied. Viewed in a more nuanced way, the question complicates the way musical sound functions in time: the way materials vibrate, the way sound emerges, the way it travels, and the way it is it is heard—processes that cannot happen irrespective of sounding bodies, resonant spaces, media of transmission and transduction, listeners’ physiologies, and their cultural biases and training. Considering how com-monplace the question is in music studies, “where is the music?” seldom rises above a qualifying aside, something we say on the way to opening a score or judging a particular performance. Our disciplines would indeed have to look different if we understood the complex answers as a meth-odological imperative. Nina Sun Eidsheim’s Sensing Sound: Singing and Listening as Vibrational Practice models what it might look like if music scholars were to stop overwriting physical evidence of sounding with cul-tural idea(l)s of what sound should be. Eidsheim’s book is sensitive to bod-ies, attentive to physics, and mindful of encultured practices of listening and sounding. It is a much-needed meeting point for musicology, sound studies, philosophy of sound, performance studies, vocal pedagogy, and those interested in theorizing difference in music.

description: This paper addresses semi-supervised semantic segmentation by exploiting a small set of images with pixel-level annotations (strong supervisions) and a large set of images with only image-level annotations (weak supervisions). Most existing approaches aim to generate accurate pixel-level labels from weak supervisions. However, we observe that those generated labels still inevitably contain noisy labels. Motivated by this observation, we present a novel perspective and formulate this task as a problem of learning with pixel-level label noise. Existing noisy label methods, nevertheless, mainly aim at image-level tasks, which can not capture the relationship between neighboring labels in one image. Therefore, we propose a graph based label noise detection and correction framework to deal with pixel-level noisy labels. In particular, for the generated pixel-level noisy labels from weak supervisions by Class Activation Map (CAM), we train a clean segmentation model with strong supervisions to detect the clean labels from these noisy labels according to the cross-entropy loss. Then, we adopt a superpixel-based graph to represent the relations of spatial adjacency and semantic similarity between pixels in one image. Finally we correct the noisy labels using a Graph Attention Network (GAT) supervised by detected clean labels. We comprehensively conduct experiments on PASCAL VOC 2012, PASCAL-Context and MS-COCO datasets. The experimental results show that our proposed semi supervised method achieves the state-of-the-art performances and even outperforms the fully-supervised models on PASCAL VOC 2012 and MS-COCO datasets in some cases.
ALMA 870 $μ$m continuum observations of HD 100546. Evidence of a giant planet on a wide orbit

description: This paper reports on a new analysis of archival ALMA $870\,μ$m dust continuum observations. Along with the previously observed bright inner ring ($r \sim 20-40\,$au), two addition substructures are evident in the new continuum image: a wide dust gap, $r \sim 40-150\,$au, and a faint outer ring ranging from $r \sim 150\,$au to $r \sim 250\,$au and whose presence was formerly postulated in low-angular-resolution ALMA cycle 0 observations but never before observed. Notably, the dust emission of the outer ring is not homogeneous, and it shows two prominent azimuthal asymmetries that resemble an eccentric ring with eccentricity $e = 0.07 $. The characteristic double-ring dust structure of HD 100546 is likely produced by the interaction of the disk with multiple giant protoplanets. This paper includes new smoothed-particle-hydrodynamic simulations with two giant protoplanets, one inside of the inner dust cavity and one in the dust gap. The simulations qualitatively reproduce the observations, and the final masses and orbital distances of the two planets in the simulations are 3.1 $M_{J}$ at 15 au and 8.5 $M_{J}$ at 110 au, respectively. The massive outer protoplanet substantially perturbs the disk surface density distribution and gas dynamics, producing multiple spiral arms both inward and outward of its orbit. This can explain the observed perturbed gas dynamics inward of 100 au as revealed by ALMA observations of CO. Finally, the reduced dust surface density in the $\sim 40-150\,$au dust gap can nicely clarify the origin of the previously detected H$_2$O gas and ice emission.

description: In this contribution we describe a novel procedure to represent fuzziness in rating scales in terms of fuzzy numbers. Following the rationale of fuzzy conversion scale, we adopted a two-step procedure based on a psychometric model (i.e., Item Response Theory-based tree) to represent the process of answer survey questions. This provides a coherent context where fuzzy numbers, and the related fuzziness, can be interpreted in terms of decision uncertainty that usually affects the rater's response process. We reported results from a simulation study and an empirical application to highlight the characteristics and properties of the proposed approach.

description: The active K2V star $ε$ Eri hosts the most nearby known extrasolar planet. With an angular separation of about 1" on average, and an age of a few to several hundred Myrs, $ε$ Eri b is one of the prime candidates for becoming the first definitive extrasolar planet imaged directly. We present a multi-epoch deep differential imaging survey performed with NACO-SDI at the VLT with the aim of finding the planet. The results are combined with recent astrometry in an attempt to further constrain the detection limits. No convincing candidate is found among the many coherent structures that constitute the residual speckle noise, which is the dominant noise at small angular scales. We present our detection limits, compare them with the estimated brightness of $ε$ Eri b, and analyze how the limits can be improved further. It is found that integration time remains a very important parameter for achieving good results, even in the speckle-dominated regimes. The results yield new, improved upper 3$σ$ limits on the absolute H-band (1.6 $μ$m) brightness of the 1.55 $M_{\rm jup}$ companion of 19.1 to 19.5 mag, depending on the specific age of the system.

description: We report measurements of time dependent decay rates for $B^0 \to D^{(*)-}π^+$ decays and extraction of CP violation parameters that depend on $ϕ_3$. Using fully reconstructed $D^{(*)}π$ events and partially reconstructed $D^{*}π$ events from a data sample that contains 386 million $B\bar{B}$ pairs that was collected near the $Υ(4S)$ resonance, with the Belle detector at the KEKB asymmetric energy $e^+ e^-$ collider, we obtain the CP violation parameters $S^+ (D^{(*)}π)$ and $S^- (D^{(*)}π)$. We obtain $S^+ (D^* π) = 0.049 \pm 0.020(\mathrm{stat}) \pm 0.011(\mathrm{sys})$, $S^- (D^* π) = 0.031 \pm 0.019(\mathrm{stat}) \pm 0.011(\mathrm{sys})$, and $S^+ (D π) = 0.031 \pm 0.030(\mathrm{stat}) \pm 0.012(\mathrm{sys})$, $S^- (D π) = 0.068 \pm 0.029(\mathrm{stat}) \pm 0.012(\mathrm{sys})$. These results are an indication of CP violation in $B^0 \to D^{*-}π^+$ and $B^0 \to D^- π^+$ decays at the $2.5 σ$ and $2.2 σ$ levels, respectively. If we use the values of $R_{D^{(*)}π}$ that are derived using assumptions of factorization and SU(3) symmetry, the branching fraction measurements for the $D_s^{(*)} π$ modes, and lattice QCD calculations, we can restrict the allowed region of $|\sin (2ϕ_1 + ϕ_3)|$ to be above 0.44 and 0.52 at 68% confidence level from the $D^* π$ and $D π$ modes, respectively.

description: Our work stems from the consideration that the spreading of a disease is modulated by the individual's perception of the infected neighborhood and his/her strategy to avoid being infected as well. We introduced a general ``cellular agent'' model that accounts for a hetereogeneous and variable network of connections. The probability of infection is assumed to depend on the perception that an individual has about the spreading of the disease in her local neighborhood and on broadcasting media. In the one-dimensional homogeneous case the model reduces to the DK one, while for long-range coupling the dynamics exhibits large fluctuations that may lead to the complete extinction of the disease.
