title: Recalibrating the SOPHIE Spectroscopic Archive to Identify Mass-Losing Exoplanets
Creators: name: McCune, Calum Scott
Publisher: name: The Open University
Year: 2016

description: Recent investigations of the WASP-12 system led to the discovery of an extensive thick and stable circumstellar gas cloud within being fed by material from the evaporating hot Jupiter planet WASP-12b (Haswell et al., 2012) (Fossati et al., 2010b). This planetary material veils the disc of the star providing a unique opportunity to probe composition via transmission spectroscopy. This would not be possible except for in this extreme scenario of catastrophic planet disintegration. Prior investigation of this system reported the anomalously low value of logR'HK = -5.50 (Knutson et al. 2010), which parameterises the activity in the Ca II H & K resonance line cores. A basal value of logR'HK = -5.1 is expected even for inactive main sequence stars (Henry et al. 1996; Wright 2004). Any stars with values below this lower limit must either be evolved or hosting similar gas shrouds. So far only a few such cases of this phenomenon have been identified but more are expected to be found within existing spectral archives. The intention of this project was to construct a reliable software pipeline for reducing large numbers of high resolution stellar spectra from the SOPHIE Echelle spectrograph with the eventual aim of producing archival measurements of the stellar activity parameter logR'HK for many stars. Integral to this goal was developing means of reliably achieving a good background subtraction of Echelle CCD spectra, specifically in the regions of the Ca II resonance lines, vital to the accurate measurement of logR'HK. The background subtraction software SKYBM was developed for this task and was then tested against existing background subtraction methods offered by the Echelle data reduction package ECHOMOP. SKYBM was found to provide the most accurate subtraction of all methods considered. This SKYBM software is therefore deemed appropriate for future work calibrating archival stellar spectra in terms of logR'HK to aid in the search for stars hosting mass losing planets.

description: The Bahamas possesses considerable natural forest resources comprising pine forests, coppice hardwood forests and mangrove forests. There has been a long history of forest exploitation dating back to the 1700s when almost the entire hardwood resource was exploited as logs for export. The last extensive exploitation ended in the early 1970s when the pine forest resources were harvested for pulpwood. Sustained yield practices were not employed during those early years. No man-made forest plantations have been established, and today, no commercial forests industries exit, with the country importing virtually all of its wood products. This paper presents some policy considerations and entrepreneurial opportunities for the sustainable utilization of the pine forests of The Bahamas.

description: Recent theories examine the role of the fractal branching vasculature as a primary site of Born scattering from soft normal tissues. These derivations postulate that the first order statistics of speckle from tissue such as the liver, thyroid, and prostate will follow a Burr distribution with a power law parameter that can be related back to the underlying power law which governs the branching network. However, the issue of scatterer spacing, or the number of cylindrical vessels per sample volume of the interrogating pulse, has not been directly addressed. This is now examined with a 3D simulation that varies the number density and the governing power law parameter of an ensemble of different sized cylinders. The Burr distribution is found to be an appropriate model for the histogram of amplitudes from speckle regions, and the parameters track the underlying conditions. These results are also tested in a more general model of rat liver scans in normal vs. abnormal conditions, and the resulting Burr distributions are also found to be appropriate and sensitive to underlying scatterer distributions. These preliminary results suggest that the classical Burr distribution may be useful in the quantification of scattering of ultrasound from soft vascularized tissues.

description: Stray livestock and the associated problems are not new or limited to underdeveloped countries. The approaches developed vary from place to place and from time to time, dependent on the particular circumstances. In 2001, Grenada experienced one of the severest dry seasons. This resulted in an intensification of problems associated with stray animals. In Carriacou, in particular, the economic impact of stray livestock is significant, limiting crop production through high costs of fencing and crop damage, degrading the environment, reducing stock number and stock breeding quality, polluting public places and putting at risks vehicular traffic Current legislation dating back to 1850's has proven to be inadequate as it has not addressed the root causes of stray animals. Some of the causes relate to (i) issues of land tenure including landlessness of livestock farmers and competition between crop and livestock farmers for space (ii) livestock management including overgrazing and overstocking (iii) socio-economic and legal issues including poverty and unemployment. To adequately respond to the negative and costly impact of stray livestock, proposed solutions need to be informed by root causes of the stray livestock problems and should be focused on sustainability. Such solutions would have implications for the Government and Ministry of Agriculture. The Ministry of Agriculture needs to review its livestock programs, making them more appropriate to the capacity of the livestock farmer. Public awareness and education on the issues surrounding livestock production and the stray livestock problem, would be critical to a process expected to reduce the number of stray animals and the improvement of livestock production in particular. Some concrete recommendations which are policy and management oriented are offered, some or all of which may be taken up in addressing the stray animals problem.

description: Due to the advantage of capacity-achieving, polar codes have been extended to the block fading channel whereas most constructions involve complex iterative-calculation. In this paper, we establish a systematic framework to analyze the error performance of polar codes in the case of block mapping and random mapping. For both the mappings, by introducing the new concept, named split polar spectrum, we derive the upper bound on the error probability of polarized channel which explicitly reveals the relationship between the diversity order L and the block-wise weight distribution of the codeword. For the special case L=2 in the block mapping, we design the enumeration algorithm to calculate the exact split polar spectrum based on the general MacWilliams identities. For arbitrary diversity order in the random mapping, with the help of uniform interleaving, we derive the approximate split polar spectrum by combining the polar spectrum and the probability of fading pattern for a specific weight. Furthermore, we propose the design criteria to construct polar codes over the block fading channel. The full diversity criterion is the primary target so as to achieve the diversity gain and the product distance criterion requires to maximize the product of the block-wise Hamming distance whereby obtain the coding gain. Guided by these design criteria, the construction metric, named polarized diversity weight (PDW) is proposed to design the polar codes in both mappings. Such a simple metric can construct polar codes with similar or better performance over those based on traditional methods in block fading channel.

description: The University of British Columbia Food System Project (UBCSP), a five-year participatory action research project of the campus food system, is in its third year of process. With the help and support of different departments and stakeholders at UBC, a series of studies have been done by the students of Agriculture Sciences (Agsc) 450. This year, scenarios addressing the desirability and feasibility of new initiatives for a sustainable campus food system were the focus of the team’s research. Students investigated diverse areas of the food system based on the inter-relations between the stakeholders: the Alma Mater Society Food and Beverage Department (AMSFBD), UBC Farm, UBC Waste Management, UBC Campus Sustainability Office (CSO) and its Social, Ecological, Economic and Development Studies (SEEDS) programs, and also the Faculty of Agricultural Science (FAS). In this context, our research team has taken on the multiple feasibility considerations for holding a successful Food Security conference using local foods at UBC. The research team will explore the guiding vision statement for all participants of the UBCSFP and link these concepts with the very hands-on process of planning a food event. We conclude that it is feasible to hold a food conference at UBC using local foods and suppliers. Nevertheless, we also stress that the feasibility will depend on several important qualifications, including some unconfirmed availability of products. We also recognize that the conference cannot be fully supplied by the local food system, and the ultimate decision about how local is ideal will have to be made by the key stakeholders. The challenges and limitations encountered in the process will also be discussed. The team will put forward recommendations for the key stakeholders in this project: the future researchers of Agricultural Sciences 450, the UBC Farm, and the AMSFBD. Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community.

description: Since the mid-1980s ORANI-F has been the main vehicle used by the research team now located at the Centre of Policy Studies (CoPS) for forecasting the average annual growth rates of macroeconomic and structural variables over the medium-run periods (six years, say). The model contains enough dynamics to accumulate variables such as capital stocks and foreign debt over the medium term but not enough to give convincing year-to-year time paths for the variables. In this paper we describe a 22-sector version of ORANI-F which is available to users outside the CoPS research team in a fully documented PC version. The CoPS team is in the process of moving to a new model, called MONASH , with enough dynamics to allow sectorally disaggregated annual forecasts which track externally projected business-cycle phenomena. We compare forecasts from MONASH and ORANI-F for the period 1990-91 to 1996-97.

description: This article investigates the optimization of yaw control inputs of a nine-turbine wind farm. The wind farm is simulated using the high-fidelity simulator SOWFA. The optimization is performed with a modifier adaptation scheme based on Gaussian processes. Modifier adaptation corrects for the mismatch between plant and model and helps to converge to the actual plan optimum. In the case study the modifier adaptation approach is compared with the Bayesian optimization approach. Moreover, the use of two different covariance functions in the Gaussian process regression is discussed. Practical recommendations concerning the data preparation and application of the approach are given. It is shown that both the modifier adaptation and the Bayesian optimization approach can improve the power production with overall smaller yaw misalignments in comparison to the Gaussian wake model.

description: This paper is ongoing work by the Centre of Policy Studies and the Impact Project that integrates the ideas of micro simulation with Computable General Equilibrium (CGE) modelling. In micro simulation the behaviour of individuals or households is modelled directly, typically using unit record data, whereas CGE models place an emphasis on market interactions and can take account of the indirect effect on households of changes in market conditions. For many policy issues (such as taxation reform), a combination of the two approaches is desirable so that both the direct and the indirect effects of such reform can be addressed. What is needed is for unit record data to be used in combination with a CGE model; that is, for the modelling of households to be combined with the modelling of markets. This can be achieved by embedding a detailed household sector in an CGE model. The solution of the model then provides distributional results for the representative households directly. In this paper a detailed household sector comprising 100 types of households — differentiated by income and demographic grouping — is developed and embedded in the MONASH Model. Simulations are conducted that measure the economy wide effects of redistributing income across these households.

description: Achieving adequate cell densities remains a major challenge in establishing economic biotechnological and biomedical processes. A possible remedy is microcarrier‐based cultivation in stirred‐tank bioreactors (STBR), which offers a high surface‐to‐volume ratio, appropriate process control, and scalability. However, despite their potential, commercial microcarriers are currently limited to material systems featuring unnatural mechanical properties and low adaptability. Because matrix stiffness and ligand presentation impact phenotypical attributes, differentiation potential, and genetic stability, biotechnological processes can significantly benefit from microcarrier systems tailorable toward cell‐type specific requirements. This study introduces hydrogel particles co‐polymerized from poly(N‐isopropylacrylamide) (PNIPAM) and acrylic acid (AAc) as a platform technology for cell expansion. The resulting microcarriers exhibit an adjustable extracellular matrix‐like softness, an adaptable gel charge, and functional carboxyl groups, allowing electrostatic and covalent coupling of cell adhesive and cell fate‐modulating proteins. These features enable the attachment and growth of L929 mouse fibroblast cells in static microtiter plates and dynamic STBR cultivations while also providing vital growth factors, such as interleukin‐3, to myeloblast‐like 32D cells over 20 days of cultivation. The study explores the effects of different educt compositions on cell‐particle interactions and reveals that PNIPAM‐co‐AAc microcarriers can provide both covalently coupled and diffusively released cytokine to adjacent cells.

description: We study a three dimensional Abelian Higgs model containing singly- and doubly-charged scalar fields coupled to a compact Abelian gauge field in the London limit. The model attracts interest because of its relevance to high-Tc superconductors with charge 1 holon and charge 2 spinon-pair fields. It contains two types of vortices carrying magnetic flux and one type of instanton-like monopoles. Using thermodynamic and topological observables we present the phase diagram in the parameter space of the gauge and holon and spinon-pair couplings. The Fermi liquid, the spin gap, the superconductor and the strange metallic phases have been identified in a wide region of parameters. The model may serve as a toy system modelling non-perturbative properties of the Yang-Mills theory.

Πρόκειται για γυναίκες, οι οποίες συχνάζουν σε καφενεία και σε μπυραρίες και αποτελούν μέρος της αθηναϊκής νυχτερινής-καλλιτεχνικής ζωής. Μέσα από την περιγραφή της εξωτερικής τους εμφάνισης φανερώνονται τα αντιθετικά δίπολα παρόν-παρελθόν, ομορφιά-ασχήμια, γηρατειά-νεότητα και ταυτόχρονα δηλώνεται η φθαρτή φύση της θεατρικής δόξας και το εφήμερο της μοντέρνας εποχής. Η σωματοποίηση των ηρωίδων και η επιφανειακή προσέγγιση του χαρακτήρα τους μαρτυρεί τις κοινωνικές αντιθέσεις και προκαταλήψεις ως προς την θέση της γυναίκας καλλιτέχνη στα τέλη του 19ου αιώνα. Επομένως, από την μια πλευρά το σώμα τους μετατρέπεται σε αντικείμενο λατρείας και χλευασμού από την ανδρική οπτική, από την άλλη αποτελεί μορφή έκφρασης της γυναικείας σεξουαλικότητας και επιθυμίας.

description: Objectives: To assess long-term (2-year) biologic treatment patterns of psoriatic arthritis (PsA) patients who initiated adalimumab, certolizumab pegol, etanercept, golimumab, or ustekinumab. Methods: Adult patients with ≥1 pharmacy or medical claim for injectable PsA biologics (index date) were identified from the Optum’s Clinformatics Data Mart (1/1/2013–12/31/2016). Adherence, persistence, post-discontinuation treatment patterns, and addition of adjunctive medications were evaluated by index biologic. Results: Of 996 patients included (mean [SD] age: 51.5 [12.6] years; female: 49.4%), the most common index biologics initiated were adalimumab (47.9%) and etanercept (34.5%). The mean [SD] proportion of days covered was 0.48 [0.32] for the index biologics. During the 24-month follow-up period, 19.7% of patients persisted on their index biologic; ustekinumab had the highest persistence rate (27.2%), followed by adalimumab (22.0%), golimumab (18.4%), certolizumab pegol (15.6%), and etanercept (15.4%). Of the 800 patients (80.3%) who discontinued their index biologic therapy, 35.0% restarted, 40.1% switched to another biologic, and 31.8% did neither during the follow-up period. The most common biologics patients switched to were adalimumab (31.2%) and ustekinumab (18.7%). Among patients who persisted with their index biologic for ≥90 days (n = 753), ≥1 adjunctive medication was added for 50.1% of patients. The most common adjunctive medications included corticosteroids (28.0% of patients), opioids (17.0%), nonsteroidal anti-inflammatory drugs (NSAIDs) (13.8%), and conventional synthetic disease modifying anti-rheumatic drugs (DMARDs) (7.3%). Conclusions: In this real-world study of use of biologic PsA therapies, 24-month persistence was low (19.7%), and treatment was frequently supplemented with adjunctive medications.

description: The largest computable general equilibrium (CGE) models currently in operation produce forecasts divided into about 100 commodities (goods and services). This level of detail may seem overwhelming to macroeconomists but is often inadequate for micro planning. For example, a . forecast for business services (a typical commodity at the 100-level) is of marginal interest in planning educational programs for sub-categories of business services such as accountancy, advertising and architecture. As a step towards generating information for micro planning, this paper describes a tops-down method for disaggregating CGE forecasts. The method relies on detailed sales data often collected by input-output sections of statistical agencies. An application is reported in which forecasts from a 114- commodity CGE model are disaggregated into forecasts for 780 commodities. Within each of the 114 core commodities, differences in prospects are forecast for sub-commodities reflecting differences in their sales patterns and in the degree to which they face import competition.

description: Out-of-time-ordered correlators (OTOC) have been extensively used as a major tool for exploring quantum chaos and also recently, there has been a classical analogue. Studies have been limited to closed systems. In this work, we probe an open classical many-body system, more specifically, a spatially extended driven dissipative chain of coupled Duffing oscillators using the classical OTOC to investigate the spread and growth (decay) of an initially localized perturbation in the chain. Correspondingly, we find three distinct types of dynamical behavior, namely the sustained chaos, transient chaos and non-chaotic region, as clearly exhibited by different geometrical shapes in the heat map of OTOC. To quantify such differences, we look at instantaneous speed (IS), finite time Lyapunov exponents (FTLE) and velocity dependent Lyapunov exponents (VDLE) extracted from OTOC. Introduction of these quantities turn out to be instrumental in diagnosing and demarcating different regimes of dynamical behavior. To gain control over open nonlinear systems, it is important to look at the variation of these quantities with respect to parameters. As we tune drive, dissipation and coupling, FTLE and IS exhibit transition between sustained chaos and non-chaotic regimeswith intermediate transient chaos regimes and highly intermittent sustained chaos points. In the limit of zero nonlinearity, we present exact analytical results for the driven dissipative harmonic system and we find that our analytical results can very well describe the non-chaotic regime as well as the late time behavior in the transient regime of the Duffing chain. We believe, this analysis is an important step forward towards understanding nonlinear dynamics, chaos and spatio-temporal spread of perturbations in many-particle open systems.

description: We model and measure patterns of order execution in order driven markets. We model these patterns as trading networks - graphs consisting of traders (nodes) and pairwise buy-sell connections among them (edges) that occured within a period of time. We con- struct a time series of over 12,000 trading networks using audit trail, transaction-level data for the September 2009 E-mini S&P 500 futures contract. We find that network metrics that quantify patterns of order execution are highly contemporaneously correlated with returns, volatility, volume, duration, and market liquidity. We also find that net- work metrics strongly Granger-cause intertrade duration and trading volume, but are not Granger-caused by them. We conclude that network metrics can be used to characterize the interaction between latent order submission strategies and transaction prices, trading volume, intertrade duration, and liquidity.

We also find that net- work metrics strongly Granger-cause intertrade duration and trading volume, but are not Granger-caused by them. We conclude that network metrics can be used to characterize the interaction between latent order submission strategies and transaction prices, trading volume, intertrade duration, and liquidity.

description: Επιστρέφοντας στην εποχή που το «κλασικό» τσίρκο βρίσκεται στην πρώτη θέση των δημοφιλών θεαμάτων, στα τέλη του 19ου και τις αρχές του 20ού αιώνα, στο άρθρο συζητούμε την έννοια της αγριότητας σε συνάρτηση με το σώμα και τα όρια μέσα στα οποία κινείται και τα οποία υπερβαίνει. Συγκεκριμένα, εξετάζουμε αφενός πώς αυτό εκτίθεται και επιτελείται σε έναν συγγενή καλλιτεχνικό χώρο, όπως τα θεάματα ποικιλιών, και αφετέρου με ποιον τρόπο κατασκευάζεται και παρουσιάζεται στις θεωρητικές και πρακτικές αναζητήσεις κύριων εκφραστών της ιστορικής πρωτοπορίας. Κύριο παράδειγμα, στην πρώτη περίπτωση, είναι οι παραστάσεις στο παρισινό Folies Bergère τον χειμώνα του 1893 και, στη δεύτερη, τα θεατρικά κείμενα του Jean Cocteau. Η έμφαση στο σώμα, και ειδικότερα στην έκθεση του ανυπότακτου, ασυνήθιστου ή εξω-ανθρώπινου σώματος, μας επιτρέπει να διερευνήσουμε και να κατανοήσουμε καλύτερα τις πολλαπλές όψεις της ιδιαίτερης λειτουργίας του τσίρκου ως χώρου όπου συνυπάρχουν και εναλλάσσονται ποικίλα και συχνά αντιθετικά στοιχεία.

description: From 1997 to March 2000, as technology stocks rose more than five-fold, institutions bought more new technology supply than individuals. Among institutions, hedge funds were the most aggressive investors, but independent investment advisors and mutual funds (net of flows) actively invested the most capital in the technology sector. The technology stock reversal in March 2000 was accompanied by a broad selloff from institutional investors but accelerated buying by individuals, particularly discount brokerage clients. Overall, our evidence is most consistent with the bubble model of Abreu and Brunnermeier (2003) where rational arbitrageurs fail to trade against bubbles until a coordinated selling effort occurs.

description: Στην Αθήνα, τη νύχτα της 20ής Απριλίου του 1863, μετά το τέλος της παράστασης του περιοδεύοντος τσίρκου Σουλιέ, δύο καλλιτέχνιδες του θιάσου «απήρχοντο εις την οικίαν των, συνοδευόμεναι υπό ενόπλου φρουράς· ότε δε έφθασαν προς το μέρος του Γερανίου, επιπίπτουσιν αίφνης στρατιώται τινες, αρπάζουσι τας γυναίκας, συμφωνούν μετ’ αυτών και οι συνοδεύοντες αυτάς περίπολοι και τας απαγάγωσιν έξω της πόλεως». Κάποιοι εθνοφύλακες «κατώρθωσαν να απαλλάξωσι την μίαν», την οποία «εγκατέλιπον χαμαί λειποθυμημένην». Στο μεταξύ, περίπολοι αναζητούσαν τη δεύτερη ηθοποιό, που είχε οδηγηθεί από τους στρατιώτες «εις απόκεντρον τι μέρος εντός ρεύματος μακράν των Αθηνών μίαν περίπου ώραν». Σύμφωνα με το ρεπορτάζ, «περί τους 35 στρατιώτας περικυκλώσαντες ήρπασαν αυτήν και διά μίας αμάξης μετήγαγον εις την Κολοκυθού, όπου και οι 35 την ητίμασαν και κατέστησαν ελεεινήν...». Το μελέτημα επιχειρεί να παρουσιάσει τα γεγονότα που προκάλεσαν μεγάλο σκάνδαλο στην εποχή. Κυρίως, όμως, προσπαθεί να συζητήσει το ζήτημα σε συνάρτηση με τις θεατρικές εξελίξεις και το ευρύτερο ιστορικό πλαίσιο της εποχής.

description: Recently some researchers have suggested that economies of scale and imperfect competition play a major role in determining the effects of exogenous policy shocks. Thus they have emphasised the need to incorporate industrial organisation features into computable general equilibrium (CGE) models. However, our knowledge of this new paradigm is still in its infancy—it is not yet clear how models of this type should be specified and to what extent their predictions are sensitive to the choice of specification. This paper describes a 23-sector CGE model of the Australian economy, based on ORANI and on Horridge (1987a and 1987b), which incorporates economies of scale and imperfect competition. The model is used to investigate whether adding these new features affects simulation results. We present results for three different types of non-competitive regime and compare these with results generated by a traditional (constant returns and perfect competition) version of the same model.

Quantum coherence and distribution of N-partite bosonic fields in noninertial frame

Subjects: subject: Quantum Physics (quant-ph)

subject: FOS: Physical sciences

description: We study the quantum coherence and its distribution of N-partite GHZ and W states of bosonic fields in the noninertial frames with arbitrary number of acceleration observers. We find that the coherence of both GHZ and W state reduces with accelerations and freezes in the limit of infinite accelerations. The freezing value of coherence depends on the number of accelerated observers. The coherence of N-partite GHZ state is genuinely global and no coherence exists in any subsystems. For the N-partite W state, however, the coherence is essentially bipartite types, and the total coherence is equal to the sum of coherence of all the bipartite subsystems.
Strong CP breaking and quark-antiquark repulsion in QCD, at finite theta
Creators: name: Faccioli, Pietro
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: This work is devoted to the study of the CP-breaking dynamics in QCD, at finite theta-angle. By working in the semi-classical limit, in which the topology of the vacuum is clustered around instantons and anti-instantons, we show that quantum fluctuations of the theta-vacuum generate an effective flavor-dependent repulsion between matter and anti-matter, inside hadrons. As a consequence, during the tunneling between the degenerate vacua, quarks and anti-quarks in the neutron migrate in opposite directions, giving rise to an oscillating electric dipole moment. We discuss a possible phenomenological implication of this effect.

Oxygen and Nitrogen in Isolated Dwarf Irregular Galaxies
Creators: name: van Zee, L.
name: Haynes, M. P.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present long slit optical spectroscopy of 67 HII regions in 21 dwarf irregular galaxies to investigate the enrichment of oxygen, nitrogen, neon, sulfur, and argon in low mass galaxies. Oxygen abundances are obtained via direct detection of the temperature sensitive emission lines for 25 HII regions; for the remainder of the sample, oxygen abundances are estimated from strong line calibrations. The direct abundance determinations are compared to the strong-line abundance calibrations of both McGaugh (1991) and Pilyugin (2000). Global oxygen and nitrogen abundances for this sample of dwarf irregular galaxies are examined in the context of open and closed box chemical evolution models. While several galaxies are consistent with closed box chemical evolution, the majority of this sample have an effective yield ~1/4 of the expected yield for a constant star formation rate and Salpeter IMF, indicating that either outflow of enriched gas or inflow of pristine gas has occurred. The effective yield strongly correlates with M_H/L_B in the sense that gas-rich galaxies are more likely to be closed systems. However, the effective yield does not appear to correlate with other global parameters such as dynamical mass, absolute magnitude, star formation rate or surface brightness. A correlation is found between the observed nitrogen-to-oxygen ratio and the color of the underlying stellar population; redder dwarf irregular galaxies have higher N/O ratios than blue dwarf irregular galaxies. The relative abundance ratios are interpreted in the context of delayed release of nitrogen and varied star formation histories.
