description: The structure of protostellar cores can often be approximated by isothermal Bonnor-Ebert spheres (BES) which are stabilized by an external pressure. For the typical pressure of $10^4k_B\,\mathrm{K\,cm^{-3}}$ to $10^5k_B\,\mathrm{K\,cm^{-3}}$ found in molecular clouds, cores with masses below $1.5\,{\rm M_\odot}$ are stable against gravitational collapse. In this paper, we analyze the efficiency of triggering a gravitational collapse by a nearby stellar wind, which represents an interesting scenario for triggered low-mass star formation. We derive analytically a new stability criterion for a BES compressed by a stellar wind, which depends on its initial nondimensional radius $ξ_{max}$. If the stability limit is violated the wind triggers a core collapse. Otherwise, the core is destroyed by the wind. We estimate its validity range to $2.54.2$ the expected wind strength according to our criterion is small enough so that the compression is slower than the sound speed of the BES and sound waves can be triggered. In this case our criterion underestimates somewhat the onset of collapse and detailed numerical analyses are required.

description: The symmetry energy and its density dependence are pivotal for many nuclear physics and astrophysics applications, as they determine properties ranging from the neutron-skin thickness of nuclei to the crust thickness and the radius of neutron stars. Recently, PREX-II reported a value of $0.283\pm0.071$ fm for the neutron-skin thickness of $^{208}$Pb, $R_{\rm skin}^{^{208}\text{Pb}}$, implying a symmetry-energy slope parameter $L$ of $106\pm37$ MeV, larger than most ranges obtained from microscopic calculations and other nuclear experiments. We use a nonparametric equation of state representation based on Gaussian processes to constrain the symmetry energy $S_0$, $L$, and $R_{\rm skin}^{^{208}\text{Pb}}$ directly from observations of neutron stars with minimal modeling assumptions. The resulting astrophysical constraints from heavy pulsar masses, LIGO/Virgo, and NICER favor smaller values of the neutron skin and $L$, as well as negative symmetry incompressibilities. Combining astrophysical data with chiral effective field theory ($χ$EFT) and PREX-II constraints yields $S_0 = 33.0^{+2.0}_{-1.8}$ MeV, $L=53^{+14}_{-15}$ MeV, and $R_{\rm skin}^{^{208}\text{Pb}} = 0.17^{+0.04}_{-0.04}$ fm. We also examine the consistency of several individual $χ$EFT calculations with astrophysical observations and terrestrial experiments. We find that there is only mild tension between $χ$EFT, astrophysical data, and PREX-II's $R_\mathrm{skin}^{^{208}\mathrm{Pb}}$ measurement ($p$-value $= 12.3\%$) and that there is excellent agreement between $χ$EFT, astrophysical data, and other nuclear experiments.

description: John Nettleship, of Five Lanes, near Caerwent, was making a celebrity appearance at the Chepstow Bookshop, where J.K. Rowling is reputed to have visited as a teenager, in order to promote the launch of the seventh and final installment in the Harry Potter series. It has been said that the 67-year-old resembles the dastardly Severus Snape, Professor of Potions at Hogwarts School of Wizardry and Witchcraft. As reported by Daniel Lombard (2007) of the South Wales Argus, that may not be the most flattering comparison - ruling his class with a rod of iron, Snape is not well-liked by the apprentice wizards. Far from taking offence, Mr. Nettleship is proud to have been an inspiration to a series that has sold 345 million copies around the world. "The first I knew was when a reporter from a national newspaper knocked on the door seven years ago and said: 'You're Professor Snape aren't you'," said the former head of science.

description: Using operator algebraic methods we show that the moment generating function of charge transport in a system with infinitely many non-interacting Fermions is given by a determinant of a certain operator in the one-particle Hilbert space. The formula is equivalent to a formula of Levitov and Lesovik in the finite dimensional case and may be viewed as its regularized form in general. Our result embodies two tenets often realized in mesoscopic physics, namely, that the transport properties are essentially independent of the length of the leads and of the depth of the Fermi sea.

description: Les municipalités jouent un rôle de plus en plus croissant dans la gouvernance environnementale au Canada. Elles adhèrent à des réseaux de municipalités qui les aident à développer des instruments d’action publique pour répondre à l’enjeu climatique. Dans cette thèse, nous étudions l’effet des réseaux sur l’élaboration et/ou la sélection des instruments d’action publique dans le contexte climatique, ainsi que leur effet sur la gouvernance environnementale. Nous nous sommes particulièrement intéressées à trois réseaux, soit deux réseaux pancanadiens, Partenaires dans la Protection du Climat et QUEST Canada, et un réseau binational, l’Alliance des Villes des Grands Lacs et du Saint-Laurent et à trois instruments d’action publique, dont deux instruments d’atténuation des changements climatiques, le plan d’action climatique PPC et la carte d’évaluation QUEST Canada et un instrument d’adaptation aux changements climatiques, le protocole CRISSP. Pour aborder ce terrain ambitieux, nous avons déployé un cadre théorique qui portait les idées que nous avons structuré en trois niveaux théoriques : les instruments (microscopique), les réseaux (méso) et la gouvernance (macroscopique). Notre cadre théorique est soutenu par un cadre méthodologique interprétatif qui repose sur les écrits de Yanow (2000) et des méthodes de recherche : une analyse documentaire, des entrevues semi-dirigées et des observations directes. Nous avons effectué le constat que les réseaux jouent un rôle primordial dans la sélection ou l’élaboration des instruments d’action publique ainsi que dans l’apprentissage des municipalités. En facilitant le flux d’information et en mettant en place des mécanismes d’apprentissage, les réseaux ont favorisé l’émergence des municipalités dans la gouvernance environnementale au Canada, cependant pas suffisamment pour restructurer la gouvernance actuelle. Nous concluons que le rôle des réseaux n’est pas négligeable, ces derniers bâtissent la capacité des municipalités et deviennent des intermédiaires politiques importants entre les municipalités et les autres paliers gouvernementaux pour gérer les relations politiques. Grâce à eux, les municipalités montent, un mouvement est définitivement en cours.

description: Occupational safety and health (OSH) still remains a challenge to the construction industry world-wide and source of worry for industry stakeholders. The Construction (Design and Management) Regulations (CDM) have been the primary tool to drive changes in the management of health and safety in the UK construction industry. Six (6) years after its latest Regulations (CDM 2015), there is a need for introspection, stock-taking and learning on current practice and how to manage more collaboratively OSH risks on construction projects. Hence, this comprehensive case study focuses on effective approaches regarding how OSH risks were managed at the pre-construction stage of a small domestic extension project.

description: When I was a doctoral student at Ohio State in the 1960s, comparative education was in its heyday. Though it was not a field in which I specialized, I was associated closely with students who did study it and took a few courses in it myself. The popularity of comparative education, however, proved to be short-lived. One of the major reasons for its decline was the identification of comparative education with the imperialist brand of American internationalism that prescribed economic development for the rest of the world, particularly for third world countries, as designed by USAID and other like-minded government agencies. That version of internationalism took a nose dive in subsequent decades, especially during the Reagan administration, as the commitment of the federal government to internationalism, except for military intervention, extinguished itself. The economically oriented neo-colonialism of USAID has recently morphed internationally into a movement for the control of education in developing countries through nongovernment agencies such as the International Monetary Fund and the World Bank. In the developed world, particularly in the USA, the design and management of education has been invaded by “educational policy” specialists, mostly economists, who seek to call the shots in the USA as well as elsewhere with prescriptions that are rather narrowly conceived, to say the least. Non-economists have tried to compete with the economists for influence and control in educational policy, domestic and international, partly through the invocation of the wonderfully elastic term, “global education.” This term simultaneously allows for various proposals calling for one kind or another brand of internationalism in American education and intending to analyze education internationally through lenses broader than the economic.

description: What is it that makes classroom experiences worthwhile? This formulation hides too much of the deep etymological inheritances of such a question: what makes a classroom experience worth, not simply zero-sum school-grade exchange, but while? What makes some experiences worthy of rest and repose, worthy of returning, worthy of tarrying and remembering, of taking time, of whiling away our lives in their presence? These questions are framed, for me, as a way to think through some of the classroom work I have witnessed over several decades of attention to a specific phenomenon: how, in vigorous and intellectually challenging and pleasurable classrooms, time and memory gather together, both things and thinking accrue and return, and there is a sense of plenitude wherein the panics of schooling are cooled in favor of good, worth while work.

Software Requirements Engineering for Transparency

Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: The last decade has seen a period of rapid development for Software Engineering, with ever larger and more complex systems making it harder for end-users to get insights into their data, operations, and functionality. Users often are not aware of the underlying processes of complex system and thus implicitly have to trust them. Trust is vital when it comes to the users’ relationship with the software. Losing the trust of external or internal stakeholders in a product can have a significant negative impact on a company’s success and reputation.A major factor of users’ trust is the transparency of a system. Transparency is the appropriate amount of information that the user needs from the system to use it successfully (achieve their goals) and exercise informed trust judgment. However, it is vital that transparency is applied correctly and to the right areas in order to enhance users’ trust.This research develops a methodology to help requirements engineers capture and formulate transparency requirements in order to enhance users’ trust by providing them with the relevant and appropriate information. To substantiate this approach, the relationship between trust and transparency is investigated in a literature study. Then, the Transparency Engineering Methodology (TEM) is developed and evaluated using a case study. TEM has been shown to create greater regard for transparency concerns in the development cycle, leading to the user being informed about how their data used and who has access to it. This degree of transparency is extended to backend and indirect collection processes where informing the user is often overlooked. The positive effect is illustrated by the quality of the output and comments from the developers, which showed that TEM can generate holistic user stories with transparency at the centre.

description: In this study, we examine the mechanical and histological properties of the bovine liver tissue stored in Lactated Ringers (control), HTK and UW solutions as a function of preservation period. The mechanical experiments are conducted with a shear rheometer on cylindrical tissue samples extracted from 3 bovine livers and the change in viscoelastic material properties of the bovine liver is characterized using the fractional derivative Kelvin-Voigt Model. Also, the histological examinations are performed on the same liver samples under a light microscope. The results show that the preservation solution and period have a significant effect on the mechanical and histological properties of the liver tissue.

description: “You can’t be queer and a fundamentalist.” That was what seemed to me a dismissive rejection of my submission by the editor of a prominent curriculum journal. The editor seemed to object to my reluctance to scathingly and utterly denounce the ideals and practices of fundamentalist Protestantism, the first and only Christian faith I have ever known. The editor doubted the relevance of my research to a curriculum studies readership in a post-911 world. Nevertheless, I consider fundamentalism quite relevant to curriculum studies today, and it is central to my discussion of a curriculum of place. I also assert that there are a number of people who identify as queer and fundamentalist; we write curriculum, teach schools, attend schools as students, serve as system administrators and board members, and continue to struggle to make sense of our conflicting identities.

description: Following the discovery of the Fe-pnictide superconductors, LDA band structure calculations showed that the dominant contributions to the spectral weight near the Fermi energy came from the Fe 3d orbitals. The Fermi surface is characterized by two hole surfaces around the $Γ$ point and two electron surfaces around the M point of the 2 Fe/cell Brillouin zone. Here, we describe a 2-band model that reproduces the topology of the LDA Fermi surface and exhibits both ferromagnetic and $q=(π,0)$ spin density wave (SDW) fluctuations. We argue that this minimal model contains the essential low energy physics of these materials.

description: Morgante Maggiore a été traduit pour la première fois en français en 1519. On compte dix rééditions durant le XVIe siècle de cette traduction anonyme sinon effectuée dans un milieu parisien, du moins publiée à Paris. Parmi elles se trouvent trois éditions lyonnaises: Jean Lambany, s. d. [c. 1529]; Olivier Arnoullet, 1548; Benoît Rigaud, 1596. En considérant les premières éditions de Morgant le geant (1519-c. 1560), il s’agit de voir, à partir de l’examen du dispositif péritextuel (titre, mise en page, illustrations) et des choix de langue, si elles présentent ou non des variantes d’un lieu de production à un autre (Paris et Lyon) et/ou d’un atelier d’impression à un autre (de Lambany à Arnoullet). A priori les transformations sont légères: il semble que l’on pratique la réédition à l’identique. Mais le toilettage éditorial, même minimal, peut cacher une volonté d’adapter l’œuvre à un lectorat que l’on se définit et dont on présuppose les goûts. Il faut donc essayer d’identifier les programmes de lecture dessinés par les configurations matérielles. Les variantes éditoriales sont-elles ou non suffisamment importantes pour conditionner des lectures différentes de l’œuvre?

Morgante Maggiore as been translated for the first time into French in 1519. There are ten editions then during the XVIth century of this anonymous translation maybe made in a Parisian workshop or at least published in Paris. Among them there are three editions published in Lyon: Jean Lambany, s. d. [c. 1529]; Olivier Arnoullet, 1548; Benoît Rigaud, 1596. “Peritextuel” environment (title, pagination, illustrations) and choices of language of Morgant le geant’s first editions (1519-c. 1560) should be the same or should change from a place of production to another (Paris and Lyon) and / or from a printing workshop to another (from Lambany’s to Arnoullet’s). A priori printers seem to practise the republication without modifications. But, even minimal, editorial grooming can hide a will to adapt the work to a specifical readership. It is thus necessary to try to identify reading programs drawn by material configurations. Are editorial variants enough important to condition different readings from the romance?

Is the Gini coefficient a stable measure of galaxy structure?
Creators: name: Lisker, Thorsten
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The Gini coefficient, a non-parametric measure of galaxy morphology, has recently taken up an important role in the automated identification of galaxy mergers. I present a critical assessment of its stability, based on a comparison of HST/ACS imaging data from the GOODS and UDF surveys. Below a certain signal-to-noise level, the Gini coefficient depends strongly on the signal-to-noise ratio, and thus becomes useless for distinguishing different galaxy morphologies. Moreover, at all signal-to-noise levels the Gini coefficient shows a strong dependence on the choice of aperture within which it is measured. Consequently, quantitative selection criteria involving the Gini coefficient, such as a selection of merger candidates, cannot always be straightforwardly applied to different datasets. I discuss whether these effects could have affected previous studies that were based on the Gini coefficient, and establish signal-to-noise limits above which measured Gini values can be considered reliable.

Crevice corrosion behaviour of nickel based alloys in neutral chloride solutions
Creators: name: Mulford, Stephen John
Publisher: name: University of British Columbia
Year: 2010

description: Crevice corrosion experiments have been conducted on Inconel 600 and Inconel 625 exposed to two principle test solutions of 1 M NaCl and 1 M NaCl + 0.01 M Na₂S₂0₃ (Sodium Thiosulphate) at three temperatures, 22°C, 55 °C and 80°C. The crevice corrosion tests were performed in a corrosion cell which was constructed from PTFE (Polytetrafluoroethylene, Teflon) and Pyrex glass. Features of the cell included the utilization of an artificial Teflon-metal crevice and provisions to monitor crevice corrosion current, active crevice corrosion potential and active crevice pH. Additional experiments included potentiodynamic anodic polarization tests on pure Ni, Alloy 600, and Alloy 625 in bulk solution environments and in simulated crevice solutions. Crevice corrosion morphology and compositional analysis of the corrosion products was studied using a scanning electron microscope equipped with an X-ray energy dispersive spectroscopy (EDS) system. Results show that crevice corrosion rates increase with increasing temperature for Alloy 600 in both principle test solutions. X-ray EDS analysis indicated that an insoluble nickel sulphide corrosion product formed on Alloy 600 in a solution of 1 M NaCl + 0.01 M Na₂S₂0₃. For the Alloy 600, in a solution of 1 M NaCl + 0.01 M Na₂S₂0₃, initiation times were significantly reduced and crevice corrosion propagation rates enhanced, as compared to Alloy 600 in 1 M NaCl. The decrease in initiation times has been attributed to the destabilizing nature of the S₂O₃⁻² species on the passive oxide film. Enhanced propagation rates have been attributed to the presence of H₂S in the crevice solution and the formation of an adsorbed species Ni(H₂S)ads which enhances the anodic dissolution reaction. The H₂S in the active crevice solution originated from the thermodynamically favoured electrochemical reduction of the S₂0₃⁻² species in the active crevice solution. Experiments on Alloy 625, which is alloyed with molybdenum, (Mo), show that it was virtually immune to crevice corrosion as compared to Alloy 600 which is not alloyed with Mo. The resistance of Alloy 625 to crevice corrosion initiation has been attributed to the stabilizing nature of MoO₂ in the passive oxide film. For an actively corroding system, the formation of the molybdate species MoO₄⁻² may act as an anodic inhibitor and effectively enhance the repassivation of the passive film.

description: We study the fit of cosmological models with two additional free parameters $N_\mathrm{eff}$ and $ξ_e$ in addition to the parameters of $Λ$CDM. We introduce extra radiation components such as hot axions or sterile neutrinos in addition to the energy density of neutrinos with large neutrino degeneracy. Then, a larger $N_\mathrm{eff}$ is allowed without spoiling Big Bang Nucleosynthesis (BBN), as positive neutrino degeneracy $ξ_e$ could improve BBN fit. By analysing the data from Planck, baryon acoustic oscillation (BAO), BBN and type-Ia supernovae (SNeIa), it can be seen that the Hubble tension can be ameliorated for $ξ_{e}\simeq 0.04$ and $0.3 \lesssim ΔN_\mathrm{eff} \lesssim 0.6$.

Short description of Higgins larvae and adult
One Higgins larva (NHMD 1177419) was so strongly contracted that it did not offer any significant information. The shape of the toes suggested though, that it is conspecific with the other, stretched and more well-preserved Higgins larva (NHMD 1177418). This larva has a fully protruded head and thin lorica with irregular, longitudinal folds (Fig. 10E–F). Body length (exclusive toes) is 140 µm, and maximum width in the anterior part of the trunk is 48 µm. The introvert has five rows of scalids, with clavoscalids in the anterior row and scalids composed of two elongate, articulating units in Rows 2 to 4. Row 5 has short scalids formed by a proximal plate, with a short, flexible distal appendage. A short, hook-shaped scalid is present middorsally, posterior to Row 5. All setae on the lorica are thin, flexible and unbranched. Anterior setae are long (anterolateral seta length = 38 µm; anteroventral seta length = 40 µm), whereas the two posterior pairs are considerably shorter (posterodorsal seta length = 25 µm; posterolateral seta length = 12 µm). Terminal setae are absent. Each toe is 27 µm long and consists of an only slightly tapering proximal part, with a hollow cavity, and a compact distal part that tapers towards its terminal tip.
The adult specimen (Fig. 10D) is strongly contracted, which prevents any examination of the head structures. The lorica is 133 µm long and has a maximum width of 114 µm. The lateral and dorsal sides have about 32 plicae, whereas the ventral side has a larger, midventral field with five transverse folds, formed by the fusion of six to eight plicae. Plicae are also fused in the posterior part of the lorica, which seems to have about 12 triangular fields, which all point towards the terminal tip of the lorica.

The theory is argued to describe two membranes moving in the orbifold R8/Z2. At level k=1 and k=2, the classical moduli space M coincides with the infra-red moduli space of SO(4) and SO(5) super Yang-Mills theory respectively. For higher Chern-Simons level, the moduli space is a quotient of M. At a generic point in the moduli space, the massive spectrum is proportional to the area of the triangle formed by the two membranes and the orbifold fixed point.

description: The two leading hypotheses for the Galactic Center Excess (GCE) in the $\textit{Fermi}$ data are an unresolved population of faint millisecond pulsars (MSPs) and dark-matter (DM) annihilation. The dichotomy between these explanations is typically reflected by modeling them as two separate emission components. However, point-sources (PSs) such as MSPs become statistically degenerate with smooth Poisson emission in the ultra-faint limit (formally where each source is expected to contribute much less than one photon on average), leading to an ambiguity that can render questions such as whether the emission is PS-like or Poissonian in nature ill-defined. We present a conceptually new approach that describes the PS and Poisson emission in a unified manner and only afterwards derives constraints on the Poissonian component from the so obtained results. For the implementation of this approach, we leverage deep learning techniques, centered around a neural network-based method for histogram regression that expresses uncertainties in terms of quantiles. We demonstrate that our method is robust against a number of systematics that have plagued previous approaches, in particular DM / PS misattribution. In the $\textit{Fermi}$ data, we find a faint GCE described by a median source-count distribution (SCD) peaked at a flux of $\sim4 \times 10^{-11} \ \text{counts} \ \text{cm}^{-2} \ \text{s}^{-1}$ (corresponding to $\sim3 - 4$ expected counts per PS), which would require $N \sim \mathcal{O}(10^4)$ sources to explain the entire excess (median value $N = \text{29,300}$ across the sky). Although faint, this SCD allows us to derive the constraint $η_P \leq 66\%$ for the Poissonian fraction of the GCE flux $η_P$ at 95% confidence, suggesting that a substantial amount of the GCE flux is due to PSs.

Retroculus

description: Retroculus Eigenmann & Bray, 1894
 Diagnosis. Retroculus is distinguished from all other cichlid genera by the presence of two exclusive characters: epibranchial lobe supported by a thickening of the first epibranchial (vs. epibranchial lobe supported by the second epibranchial, or by a laminar expansion of the first epibranchial; Fig. 1); and the presence of a vomero-palatine apparatus on roof of the mouth (vs. roof of mouth not distinctively specialized; Fig. 2). Retroculus can also be distinguished by a combination of the following diagnostic characters: the presence of two lachrymal plates plus five tubular infraorbitals (Fig. 3); a first tubular infraorbital only posteriorly associated with the orbit; the lip folds meeting without overlap at the corner of the mouth (African lips of Kullander, 1986; or type-I lip of Stiassny, 1987); presence of two supraneurals; the seven lateralis canal foramina in the preopercle; the five lateralis canal foramina on the dentary; a black blotch on the anterior soft dorsal-fin rays; the orobranchial mucosa laterally covered by papillae; by the presence of skin flaps and a lack of microbranchiospines along the external margin of the first ceratobranchial; attachment of the ligament hypohyal-hypobranchial 1 along the antero-medial spiny process of the first hypobranchial (Fig. 4); supracleithrum laterosensory canal posteroventrally angled (Fig. 5); posterior portion of the dentigerous arm of the dentary slender; and rakers at base of epibranchial lobe (Fig. 6 B).

description: While Efimov physics in ultracold atoms is usually modeled with an isolated Feshbach resonance many real world resonances appear in close vicinity to each other and are therefore overlapping. Here we derive a realistic model based on the mutual coupling of an open channel and two closed molecular channels while neglecting short-range physics as permitted by the narrow character of the considered resonances. The model is applied to three distinct scenarios with experimental relevance. We show that the effect of overlapping resonances is manifested most strikingly at a narrow resonance in whose vicinity there is a slightly narrower one. In this system the Efimov ground state extends not only over the scattering length zero crossing between the two resonances but also over the pole of the second resonance to finally meet the dissociation threshold below it. In the opposite scenario, when a narrow resonance is considered in the vicinity of a slightly broader one, we observe that the Efimov features are pushed to lower binding energies and smaller scattering lengths by a significant factor facilitating their experimental investigation. Both scenarios are referenced to the case of two narrow resonances which are far enough away from each other to be effectively decoupled. In this case the two-channel model results are recovered. Finally, we analyze the rich excitation spectrum of the system and construct and explain its nodal pattern.

description: Recently, the importance of the electronic many-body effect in the dark matter (DM) detection has been recognized and a coherent formulation of the DM-electron scattering in terms of the dielectric response of the target material has been well established in literatures. In this paper, we put relevant formulas into practical density functional theory (DFT) estimation of the excitation event rates for the diamond and silicon semiconductor targets. Moreover, we compare the event rates calculated from the energy loss functions with and without the local field effects. For a consistency check of this numerical method, we also compare the differential spectrum and detection reach of the silicon with those computed with the $\mathtt{GPAW}$ code. It turns out that this DFT approach is quite consistent and robust. As an interesting extension, we also investigate the in-medium effect on the detection of the solar-reflected DM flux in silicon-based detectors, where the screening effect is found to be also remarkable in the optically thick regime, and to turn insignificant in the optically thin regime, depending on the energies of the reflected DM particles.

A Radio and Optical Polarization Study of the Magnetic Field in the Small Magellanic Cloud

description: We present a study of the magnetic field of the Small Magellanic Cloud (SMC), carried out using radio Faraday rotation and optical starlight polarization data. Consistent negative rotation measures (RMs) across the SMC indicate that the line-of-sight magnetic field is directed uniformly away from us with a strength 0.19 +/- 0.06 microGauss. Applying the Chandrasekhar-Fermi method to starlight polarization data yields an ordered magnetic field in the plane of the sky of strength 1.6 +/- 0.4 microGauss oriented at a position angle 4 +/- 12 degs, measured counter-clockwise from the great circle on the sky joining the SMC to the Large Magellanic Cloud (LMC). We construct a three-dimensional magnetic field model of the SMC, under the assumption that the RMs and starlight polarization probe the same underlying large-scale field. The vector defining the overall orientation of the SMC magnetic field shows a potential alignment with the vector joining the center of the SMC to the center of the LMC, suggesting the possibility of a "pan-Magellanic'' magnetic field. A cosmic-ray driven dynamo is the most viable explanation of the observed field geometry, but has difficulties accounting for the observed uni-directional field lines. A study of Faraday rotation through the Magellanic Bridge is needed to further test the pan-Magellanic field hypothesis.

description: The pure braid group Γof a quadruply-punctured Riemann sphere acts on the SL(2,C)-moduli M of the representation variety of such sphere. The points in M are classified into Γ-orbits. We show that, in this case, the monodromy groups of many explicit solutions to the Riemann-Hilbert problem are subgroups of SU(2). Most of these solutions are examples of representations that have dense images in SU(2), but with finite Γ-orbits in M. These examples relate to explicit immersions of constant mean curvature surfaces.

description: The cubic-kilometre neutrino telescope, which consists of large-scale 3D-arrays of photomultiplier tubes (PMTs) currently under construction on the Mediterranean seabed, relies on accurate calibration procedures in order to answer its science goals. These proceedings present the gain calibration method used in KM3NeT, which is based on highly compressed PMT hit information. In particular, it is shown that the PMT gains can be tuned to within 2% of the nominal value, based on the measured single photoelectron time-over-threshold distribution of each PMT.

description: Occupational safety and health (OSH) still remains a challenge to the construction industry world-wide and source of worry for industry stakeholders. The Construction (Design and Management) Regulations (CDM) have been the primary tool to drive changes in the management of health and safety in the UK construction industry. Six (6) years after its latest Regulations (CDM 2015), there is a need for introspection, stock-taking and learning on current practice and how to manage more collaboratively OSH risks on construction projects. Hence, this comprehensive case study focuses on effective approaches regarding how OSH risks were managed at the pre-construction stage of a medium-size commercial refurbishment project.

description: In light of the recent data from BES collaboration for $χ_{c0}\to VV$, $PP$ and $SS$, and from CLEO-c for $ηη$, $η^\primeη^\prime$ and $ηη^\prime$, we present a detailed analysis of the decays of heavy quarkonia into light meson pairs such as $χ_{c0,2}\to VV$, $PP$ and $SS$ in a recently proposed parametrization scheme. An overall agreement with the data is achieved in $χ_{c0,2}\to VV$ and $PP$, while in $χ_{c0}\to SS$ we find that a possible existence of glueball-$q\bar{q}$ mixings is correlated with the OZI-rule violations, which can be further examined at CLEO-c and BESIII in $χ_{c0}\to SS$ measurement.

EAZY: A Fast, Public Photometric Redshift Code

Publisher: name: arXiv

description: We describe a new program for determining photometric redshifts, dubbed EAZY. The program is optimized for cases where spectroscopic redshifts are not available, or only available for a biased subset of the galaxies. The code combines features from various existing codes: it can fit linear combinations of templates, it includes optional flux- and redshift-based priors, and its user interface is modeled on the popular HYPERZ code. A novel feature is that the default template set, as well as the default functional forms of the priors, are not based on (usually highly biased) spectroscopic samples, but on semi-analytical models. Furthermore, template mismatch is addressed by a novel rest-frame template error function. This function gives different wavelength regions different weights, and ensures that the formal redshift uncertainties are realistic. We introduce a redshift quality parameter, Q_z, that provides a robust estimate of the reliability of the photometric redshift estimate. Despite the fact that EAZY is not "trained" on spectroscopic samples, the code (with default parameters) performs very well on existing public datasets. For K-selected samples in CDF-South and other deep fields we find a 1-sigma scatter in dz/(1+z) of 0.034, and we provide updated photometric redshift catalogs for the FIRES, MUSYC, and FIREWORKS surveys.

description: We consider a hidden sector with a vectorlike confining gauge theory like QCD with $N_{h,c}$ colors and $N_{h,f}$ light quarks ${\cal Q}_h$ in the hidden sector. Then a scale $Λ_H$ would be generated by dimensional transmutation, and chiral symmetry breaking occurs in the hidden sector. This scale $Λ_H$ can play a role of the SM Higgs mass parameter, triggering electroweak symmetry breaking (EWSB). Furthermore the lightest mesons in the hidden sector is stable by flavor conservation of the hidden sector strong interaction, and could be a good cold dark matter (CDM). We study collider phenomenology, and relic density and direct detection rates of the CDM of this model.
