description: The Welsh language has been subject to much political attention in Wales. The Welsh Government’s vision for reaching a million Welsh speakers by 2050, means numbers would need to double in just over 30 years. In addition to growth driven by formal education policy, the Welsh Language Commissioner believed that sport could play a key role in achieving this ambitious target. Sport could provide a context where children, many of whom would only use Welsh in school, could interact, play and socialise in Welsh. This research provides a critical analysis of whether sport in the community, e.g. local swimming and gymnastics clubs, can be a vehicle for promoting the use of Welsh among young people beyond the school gate. A case study approach was adopted in order to obtain the perspectives of young people and community sport providers. Qualitative research methods were used for data collection including a sustained period of participant observation, follow-up interviews and focus groups. The research also focused on gaining a broader understanding of the policy landscape regarding community sport and the Welsh language. Policy informer interviews were undertaken with individuals working at the local, regional and national levels. These interviews looked to understand the research question in a wider context and provide a critical analysis of the challenges and opportunities associated with the development of a minority language. Some of the key findings related to: the importance of the local language context of the case study area; the behaviours and attitudes of young people towards the language (both within and beyond the school gate); the availability of qualified Welsh speaking coaches and volunteers to promote the Welsh language; and the perceptions of significant others which can lead (intentionally and unintentionally) to the marginalisation of minority language speakers. There were also a number of wider policy challenges identified and these included: the impact of Brexit; partnership working; resources; and communication. A key conclusion was that community sport can offer opportunities for the development of the Welsh language and that linguistic capital is an important feature of community cohesion and identity. For this to be achieved, however, some challenges need to be overcome including tackling negative attitudes and behaviours of young people and community sport deliverers. Some opportunities were also identified which merit further exploration including partnership working, the development of educational resources, the need to raise awareness of Welsh in Further and Higher Education, and to promote speaking Welsh in professional and personal development.

description: We study the dynamics of an atomic two-level system decaying by spontaneous emission of light. Subject to continuous detection of the radiated field, the system tends with certainty to the ground state in the long time limit, but at initial times the excited state population exhibits non-trivial stochastic behavior. Employing methods from Ito calculus, we characterize this behavior, and we show, for example, that the emitter, as a result of in-phase homodyne measurements, may become fully excited during the decay process while heterodyne and out of phase homodyne measurements do not drive the atom completely into the excited state.

description: Ο αμίαντος αποτελεί ένα πυριτικό ορυκτό το οποίο, λόγω των χρήσιμων χημικών και φυσικών ιδιοτήτων του, χρησιμοποιήθηκε ευρέως κατά τον 20ο αιώνα σε πληθώρα εφαρμογών. Η περιεκτικότητά του στα διάφορα προϊόντα ποικίλει από 5 έως και 100%. Αν και υπάρχουν αρκετοί τύποι αμιάντου, ο πιο διαδεδομένος σε χρήση είναι ο χρυσοτίλης ή λευκός αμίαντος και υπολογίζεται πως τα αμιαντούχα προϊόντα με χρυσοτίλη αγγίζουν ένα ποσοστό πάνω από 90%. Η Ελλάδα υπήρξε παραγωγός χώρα αμιάντου κατέχοντας την 7η θέση παγκοσμίως και μέχρι πριν λίγα χρόνια στο Ζιδάνι της Κοζάνης λειτουργούσε το μεγαλύτερο ορυχείο ανοικτού τύπου αμιάντου στα Βαλκάνια με παραγωγή 100.000 τόνους χρυσοτίλη/έτος.
Σήμερα ο αμίαντος θεωρείται ένας από τους σημαντικότερους παράγοντες καρκινογένεσης (κυρίως μεσοθηλίωμα και καρκίνος του πνεύμονα), στην περίπτωση που οι ίνες του εισχωρήσουν στον ανθρώπινο οργανισμό. Η διαπιστωμένη, πλέον, ενοχοποίησή του για καρκινογένεση έχει οδηγήσει πολλές χώρες στη λήψη αυστηρών μέτρων για τον περιορισμό της χρήσης του και σταδιακά την πλήρη απαγόρευσή του. Στην Ελλάδα και την υπόλοιπη Ευρώπη η νομοθεσία θεσπίζει ένα αρκετά αυστηρό πλαίσιο απαγορεύοντας την εξόρυξη και τη χρήση του αμιάντου.
Σε περίπτωση που ένα αμιαντούχο υλικό χάσει τις ιδιότητές του, εγκαταλειφτεί ή πρόκειται να εγκαταλειφτεί χαρακτηρίζεται ως απόβλητο αμιάντου (Asbestos Containing Waste – ACW) και κατατάσσεται στα επικίνδυνα απόβλητα για τα οποία προβλέπεται ιδιαίτερη διαχείριση.
Έχουν αναπτυχθεί διάφορες μέθοδοι επεξεργασίας όπως χημικές, θερμικές, μηχανικές κ.α. Η πιο κοινή μέθοδος είναι η διάθεση των αμιαντούχων υλικών σε ΧΥΤΕΑ, η οποία δεν αποτελεί βιώσιμη λύση αφού απαιτείται τεράστιος όγκος για διάθεση των αποβλήτων και η ίδια η μέθοδος δεν προκαλεί καμία μείωση στην τοξικότητα του αμιάντου.
Στην παρούσα διπλωματική εργασία εξετάστηκε η επίδραση μετρίως ισχύος και τοξικότητας οργανικού οξέoς, και πιο συγκεκριμένα του οξαλικού οξέος, στην αποδόμηση των καρκινογόνων ινών καθαρού χρυσοτιλικού αμιάντου από τα Μεταλλεία Αμιάντου Βορείου Ελλάδος (ΜΑΒΕ) και σε κομμάτια αμιαντοτσιμέντου (eternit). Μετά το πέρας των αντιδράσεων, εκτός από την αποσύνθεση του κρυσταλλικού πλέγματος του αμιάντου, έλαβε χώρα ανάκτηση οξειδίου του μαγνησίου (ΜgO) από τα προϊόντα της αντίδρασης, υλικό με μεγάλη αξία και εξαιρετικά χρήσιμο σε αρκετές βιομηχανικές εφαρμογές.
Αναλύσεις FTIR και XRD έδειξαν ότι σε 10 μέρες το στρώμα βρουσίτη Mg(OH)2 στην επιφάνεια των ινών του αμιάντου έχει καταστραφεί σε μεγάλο βαθμό προκαλώντας μετατροπή του χρυσοτίλη σε άμορφο πυριτικό ορυκτό. Παρατηρήθηκε η δημιουργία ενός νέου ορυκτού, του οξαλικού μαγνησίου (Glushinskite). Με θερμική επεξεργασία σε θερμοκρασία 480 οC έγινε πλήρης μετατροπή του σε καθαρό ΜgO. Τέλος, η εφαρμογή οξαλικού οξέoς με πινέλο σε αμιαντοτσιμέντο δεν επέφερε κάποια επίδραση στην ινώδη δομή του χρυσοτίλη.
Continuous and smooth envelopes of topological algebras

description: Since the time when the first optical instruments have been invented, an idea that the visible image of an object under observation depends on tools of observation became commonly assumed in physics. A way to formalize it in mathematics is the construction that assigns to an arbitrary object $A$ in a category $K$ its envelope $\text{Env}_\varPhi^\varOmega A$ in a given class of morphisms (a class of representations) $\varOmega$ with respect to a given class of morphisms (a class of observation tools) $\varPhi$. It turns out that if we take a sufficiently wide category of topological algebras as $K$, then each choice of the classes $\varOmega$ and $\varPhi$ defines a "projection of functional analysis into geometry", and the standard "geometric disciplines", like complex geometry, differential geometry and topology, become special cases of this construction. This gives a formal scheme of "categorical construction of geometries" with many interesting applications, in particular, "geometric generalizations of the Pontryagin duality" (to the classes of non-commutative groups). In this paper we describe this scheme in topology and in differential geometry.

The Leadership Role and Influence of Team Captaincy in Professional Rugby Union
Creators: name: Lowther, Mark
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Sport and leisure management

description: The aim of the study and research question was to understand the leadership role, interpersonal style and impact of the team captain in a professional rugby union context and evaluate the implications of the findings for the practice (and development) of team captaincy. Loughead et al. (2006) indicated that the majority of sport leadership research has focused on the coach but that athlete leadership within a team was an important source of influence. Much of the literature in the team captaincy field was based on the experiences of varsity populations and there was scope, as Loughead et al. (2006) proposed, for future research to examine athlete leadership at other levels of competition including professional sport. The study was framed by an interpretivist paradigm and a qualitative methodology. The research was based on a single, instrumental case study, the Southern Warriors (pseudonym), a professional rugby union team classified as competitive elite (Swann et al., 2015) who played in a top tier league. Data collection techniques included semi structured and informal conversational interviews, overt participant observation (over the course of a season) and archival research. Data was analysed using reflexive thematic analysis (Braun and Clarke, 2006). The study found that the professional rugby context was distinguished by three dimensions - commercial (gladiatorial) spectacle, demanding (and dynamic) endeavour and collective camaraderie; that the team captain performed three key roles - environment influencer, game shaper and stakeholder ambassador; that the influencing style of the team captain was based on three key dimensions - personal qualities, process skills and agile practice and finally, that the team captain impacted three areas - team purpose, team performance and team satisfaction. The study provided original contributions to the body of knowledge through “real world” professional sport insights (a complex and pluralist ecosystem of competing and sometimes contradictory organisational dynamics); by further developing the current taxonomy of leadership roles and revising the current definition of athlete leadership. The study also provided insights into leadership currency and proposed a framework of key in game leadership evaluation indicators. Practical implications of the research findings for the effective practice of team captaincy included terms of reference for the supervisory leadership group, a team captain job description, a team captain person specification, a team captain (i) self-appraisal process and (ii) 360 appraisal process. Recommended future avenues of inquiry included evaluation of the social leadership role off the field, the evaluation of leadership role and style during a game and evaluation of the selection process and development activities for team captains.

description: We construct algebraically closed fields containing an algebraic closure of the field of power series in several variables over a characteristic zero field. Each of these fields depends on the choice of an Abhyankar valuation and are constructed via the Newton-Puiseux method. Then we study more carefully the case of monomial valuations and we give a result generalizing the Abhyankar-Jung Theorem for monic polynomials whose discriminant is weighted homogeneous.

Equivariant weight filtration for real algebraic varieties with action

Subjects: subject: Algebraic Geometry (math.AG)
subject: FOS: Mathematics

description: We show the existence of an equivariant weight filtration on the equivariant homology of real algebraic varieties equipped with a finite group action, by applying group homology onto the weight complex of McCrory and Parusiński. The group action enriches the information contained in the induced equivariant weight spectral sequence from which we can not extract finite additivity directly if the group is of even order. Still, we manage to construct additive invariants from its elementary bricks, and prove that they are induced from the very equivariant geometry of real algebraic varieties with action, and that they coincide with Fichou's equivariant virtual Betti numbers in some cases. In the case of the two-elements group, we recover these through the use of globally invariant chains and the equivariant version of Guill{é}n and Navarro Aznar's extension criterion.

Patterns of interval correlations in neural oscillators with adaptation

Publisher: name: arXiv
Year: 2013
Subjects: subject: Neurons and Cognition (q-bio.NC)
subject: FOS: Biological sciences

description: Neural firing is often subject to negative feedback by adaptation currents. These currents can induce strong correlations among the time intervals between spikes. Here we study analytically the interval correlations of a broad class of noisy neural oscillators with spike-triggered adaptation of arbitrary strength and time scale. Our weak-noise theory provides a general relation between the correlations and the phase-response curve (PRC) of the oscillator, proves anti-correlations between neighboring intervals for adapting neurons with type I PRC and identifies a single order parameter that determines the qualitative pattern of correlations. Monotonically decaying or oscillating correlation structures can be related to qualitatively different voltage traces after spiking, which can be explained by the phase plane geometry. At high firing rates, the long-term variability of the spike train associated with the cumulative interval correlations becomes small, independent of model details. Our results are verified by comparison with stochastic simulations of the exponential, leaky, and generalized integrate-and-fire models with adaptation.

description: Matrix completion has been well studied under the uniform sampling model and the trace-norm regularized methods perform well both theoretically and numerically in such a setting. However, the uniform sampling model is unrealistic for a range of applications and the standard trace-norm relaxation can behave very poorly when the underlying sampling scheme is non-uniform. In this paper we propose and analyze a max-norm constrained empirical risk minimization method for noisy matrix completion under a general sampling model. The optimal rate of convergence is established under the Frobenius norm loss in the context of approximately low-rank matrix reconstruction. It is shown that the max-norm constrained method is minimax rate-optimal and yields a unified and robust approximate recovery guarantee, with respect to the sampling distributions. The computational effectiveness of this method is also discussed, based on first-order algorithms for solving convex optimizations involving max-norm regularization.

description: Background: Incidence of pelvic ring fractures has increased over the past four decades, especially after low-impact trauma—classified as fragility fractures of the pelvis (FFP). To date, there is a lack of biomechanical evidence for the superiority of one existing fixation technique over another. An FFP type IIc was simulated in 50 artificial pelvises, assigned to 5 study groups: Sacroiliac (SI) screw, SI screw plus supra-acetabular external fixator, SI screw plus plate, SI screw plus retrograde transpubic screw, or S1/S2 ala–ilium screws. The specimens were tested under progressively increasing cyclic loading. Axial stiffness and cycles to failure were analysed. Displacement at the fracture sites was evaluated, having been continuously captured via motion tracking. Results: Fixation with SI screw plus plate and SI screw plus retrograde transpubic screw led to higher stability than the other tested techniques. The S1/S2 ala–ilium screws were more stable than the SI screw or the SI screw plus external fixator. Conclusions: In cases with displaced fractures, open reduction and plate fixation provides the highest stability, whereas in cases where minimally invasive techniques are applicable, a retrograde transpubic screw or S1/S2 ala–ilium screws can be considered as successful alternative treatment options.

title: Epidemiology and control of Ebola Virus Disease (EVD) in Sierra Leone: analysis of data from the Médecins Sans Frontières (MSF) response, 2014-15
Creators: name: Caleo, G
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2021

description: Aims and Objectives This thesis stems from work conducted with Médecins Sans Frontières in Sierra Leone, during the 2014- 2015 Ebola virus disease (EVD) outbreaks. The thesis addresses 3 main public health knowledge gaps and aims to improve the response to future EVD outbreaks by: 1) Understanding the factors that influenced EVD transmission and community compliance with con- trol measures; 2) Estimating the performance of the WHO EVD case definition, and what components could improve it; 3) Estimating the design effect and mortality rates, and discussing how to improve future surveys for highly-clustered diseases. Methods The methods corresponding to each gap were: 1) A mixed-methods study in one village experiencing sustained transmission in Sierra Leone; 2) A review and meta-analysis exploring performance of WHO EVD case definitions against laboratory confirmed EVD; 3) Two population-based clustered surveys, in Sierra Leone. Results Study 1 identified that non-compliance with public health guidelines was a consequence of the failure of the response to orientate itself according to the needs and values of the community. Study 2 estimated that the WHO EVD case definition performed sub-optimally to identify cases (sen- sitivity 81·5% (74·1-87·2%); specificity 35·7% (28·5-43·6%)). Inclusion of intense fatigue as a key symptom and contact history could improve performance, but these changes would require collabora- tion with, and trust of, affected communities. Study 3 identified a high degree of clustering in community-based surveys of EVD, this contributed to imprecise mortality estimates, which have limited utility when assessing the impact of disease. Estimated the design effect along with methodological suggestions provided can inform future surveys for similar highly clustered diseases. Conclusion The thesis highlights that outbreak patterns are linked to social and cultural environments. Community influence key public health practices (i.e. case definitions). Recognition of transmission risks from responding organization requires a respectful and compassionate approach, understanding of social norms and adapted community-lead interventions.
The "Wow! signal" of the terrestrial genetic code

description: It has been repeatedly proposed to expand the scope for SETI, and one of the suggested alternatives to radio is the biological media. Genomic DNA is already used on Earth to store non-biological information. Though smaller in capacity, but stronger in noise immunity is the genetic code. The code is a flexible mapping between codons and amino acids, and this flexibility allows modifying the code artificially. But once fixed, the code might stay unchanged over cosmological timescales. Thus, it represents a reliable storage for an intelligent signature, if that conforms to biological and thermodynamic requirements. As the actual scenario for the origin of terrestrial life is far from being settled, the proposal that it might have been seeded intentionally cannot be ruled out. A statistically strong signal in the genetic code is then a testable consequence of such scenario. Here we show that the terrestrial code displays a thorough precision orderliness matching the criteria to be considered an informational signal. Simple arrangements of the code reveal an ensemble of arithmetical and ideographical patterns of the same symbolic language. Accurate and systematic, these underlying patterns appear as a product of precision logic and nontrivial computing rather than of stochastic processes. The patterns are profound to the extent that the code mapping itself is uniquely deduced from their algebraic representation. The signal displays readily recognizable hallmarks of artificiality. Besides, extraction of the signal involves logically straightforward but abstract operations, making the patterns essentially irreducible to any natural origin. Plausible way of embedding the signal into the code and possible interpretation of its content are discussed. Overall, while the code is nearly optimized biologically, its limited capacity is used extremely efficiently to store non-biological information.

description: In this paper we propose a Bayesian answer to testing problems when the hypotheses are not well separated. The idea of the method is to study the posterior distribution of a discrepancy measure between the parameter and the model we want to test for. This is shown to be equivalent to a modification of the testing loss. An advantage of this approach is that it can easily be adapted to complex hypotheses testing which are in general difficult to test for. Asymptotic properties of the test can be derived from the asymptotic behaviour of the posterior distribution of the discrepancy measure, and gives insight on possible calibrations. In addition one can derive separation rates for testing, which ensure the asymptotic frequentist optimality of our procedures.

description: It is shown that a general model for particle detection in combination with a linear application of the Wigner rotations, which correspond to momentum-dependent changes of the particle spin under Lorentz transformations, to the state of a massive relativistic particle in a superposition of two counter-propagating momentum states leads to a paradox. The paradoxical behavior is that the probability of finding the particle at different positions would depend on the reference frame. A solution to the paradox is given when the physical construction of the corresponding state is taken into account, suggesting that we cannot in general linearly apply the Wigner rotations to a quantum state without considering the appropriate physical interpretation.

We changed the example used to show that the linear application of the Wigner rotations to the state of a massive relativistic particle in a superposition of two counter-propagating momentum states leads to a paradox.

description: Education policies worldwide are increasingly being realigned to the economic prosperity, vertical mobility and social citizenship of the people. Human capital theorists have long underlined the need for investment in building productive human capital in any organisation or a society. Our educational policies developed at the national level are often driven by some overarching goals. Such a top-down approach in implementing those policies on the ground, especially in a specific region like North East India, needs a bottom-up restructuring. There is an urgent need to re-examine our education policies at the regional level to provide an environment where individuals can utilise their education and training to gain employment, improve their living standards, and contribute to the social development of the area.

description: We study (2+1)-dimensional single step model (SSM) for crystal growth including both deposition and evaporation processes parametrized by a single control parameter $p$. Using extensive numerical simulations with a relatively high statistics, we estimate various interface exponents such as roughness, growth and dynamic exponents as well as various geometric and distribution exponents of height clusters and their boundaries (or iso-height lines) as function of $p$. We find that, in contrary to the general belief, there exists a critical value $p_c\approx 0.25$ at which the model undergoes a roughening transition from a rough phase with $pp_c$, asymptotically in the Edwards-Wilkinson (EW) class. We validate our conclusion by estimating the effective roughness exponents and their extrapolation to the infinite-size limit.

description: Nineteenth-century US patent law drew a clear distinction between human innovations, which were patentable, versus products of nature, which were not. My thesis explores the transformation of nineteenth-century prairies into domesticated, commercial farmlands in the context of patent law. The trajectories of two intersecting phenomena in Marion County, Kansas, from 1860 to 1890 offer illuminating perspectives. One, the unpatented Turkey Red wheat brought to Kansas by the Russian Mennonites in 1874, was a prodigious wheat varietal from the Russian steppes, which quickly dominated the domesticated prairies of the Great Plains. The other phenomenon, the patented, revolutionary McCormick Reaper, could harvest vast lands with great efficiency. Geography, climate, and commercial forces brought patented mechanical innovation and un-patented nature into an abrupt symbiotic relationship, and forever transformed the Great Plains.

description: Polycrystalline YMn1-xFexO3 (YMFO_x) (0 <= x <= 0.1) compounds have been prepared in single phase and characterized by synchrotron X-ray diffraction, X-ray absorption near edge spectroscopy, magnetization, and dielectric measurements. Iron-substitution in hexagonal YMnO3 causes intra-lattice changes exceeding those of the lattice cell. XANES provide mixed-valence Mn3+/Mn4+ and Fe4+ charge states in these manganites, consistent with the observed decrease of the effective magnetic moment with Fe-doping. Magnetization M(T) evidence antiferromagnetic (AFM) ordering of the specimens with little weak ferromagnetism, and the metrices of exchange interaction suppress with Fe-doping, attributed to the lengthening of the Mn-O planar bond lengths. Dielectric ε'(T) results showing highly doping-dependent anomaly at T_N indicate linear magneto-electric coupling.

Can you play? An analysis of video game user-generated content policies

description: User-generated content (UGC) is notoriously difficult to regulate under the, often rightsholder-centric, default copyright regime. As an alternative regulatory mechanism, this working paper explores how the video game industry regulates user creativity through contract, not copyright, creating a parallel community system of exclusive rights and user exceptions. The working paper examines the UGC policies of 30 popular game titles, identifying seven different types of UGC activities and the varying degrees to which they are permitted: either entirely without condition; with conditions; or wholly prohibited. In doing so, the paper identifies industry trends in regulating user creativity, and how this responsive contractual tool acts as a gateway for reflection for copyright reform.

description: We prove that a graph whose chromatic number is 2 is a homotopy test graph. We also prove that there is a graph $K$ with two involutions $γ_1$ and $γ_2$ such that $(K,γ_1)$ is a Stiefel-Whitney test graph, but $(K,γ_2)$ is not. These are answers to some of the problems suggested by Kozlov.

Kerr Isolated Horizons in Ashtekar and Ashtekar-Barbero Connection Variables

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The Ashtekar and Ashtekar-Barbero connection variable formulations of Kerr isolated horizons are derived. Using a regular Kinnersley tetrad in horizon-penetrating Kruskal-Szekeres-like coordinates, the spin coefficients of Kerr geometry are determined by solving the first Maurer-Cartan equation of structure. Isolated horizon conditions are imposed on the tetrad and the spin coefficients. A transformation into an orthonormal tetrad frame that is fixed in the time gauge is applied and explicit calculations of the spin connection, the Ashtekar and Ashtekar-Barbero connections, and the corresponding curvatures on the horizon 2-spheres are performed. Since the resulting Ashtekar-Barbero curvature does not comply with the simple form of the horizon boundary condition of Schwarzschild isolated horizons, i.e., on the horizon 2-spheres, the Ashtekar-Barbero curvature is not proportional to the Plebanski 2-form, which is required for an SU(2) Chern-Simons treatment of the gauge degrees of freedom in the horizon boundary in the context of loop quantum gravity, a general method to construct a new connection whose curvature satisfies such a relation for Kerr isolated horizons is introduced. For the purpose of illustration, this method is employed in the framework of slowly rotating Kerr isolated horizons.

description: We present measurements of the anisotropic galaxy clustering from the Data Release 9 (DR9) CMASS sample of the SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS). We analyze the broad-range shape of the monopole and quadrupole correlation functions to obtain constraints, at the effective redshift $z=0.57$ of the sample, on the Hubble expansion rate $H(z)$, the angular-diameter distance $D_A(z)$, the normalized growth rate $f(z)σ_8(z)$, the physical matter density $Ω_m h^2$, and the biased amplitude of matter fluctuation bσ_8(z). We obtain {$H(0.57)$, $D_A(0.57)$, $f(0.57)σ_8(0.57)$, $Ω_m h^2$, $bσ_8(0.57)$} = {$87.6_{-6.8}^{+6.7}$, $1396\pm73$, $0.126_{-0.010}^{+0.008}$, $1.19\pm0.14$, $0.428\pm0.066$} and their covariance matrix as well. The parameters which are not well constrained by our of galaxy clustering analysis are marginalized over with wide flat priors. Since no priors from other data sets (i.e., CMB) are adopted and no dark energy models are assumed, our results from BOSS CMASS galaxy clustering alone may be combined with other data sets, i.e. CMB, SNe, lensing or other galaxy clustering data to constrain the parameters of a given cosmological model. We show that the major power on constraining dark energy from the anisotropic galaxy clustering signal, as compared to the angular-averaged one (monopole), arises from including the normalized growth rate $f(z)σ_8(z)$. In the case of the wCDM cosmological model our single-probe CMASS constraints, combined with CMB (WMAP9+SPT), yield a value for the dark energy equation of state parameter of $w=-0.90\pm0.11$. Therefore, it is important to include $f(z)σ_8(z)$ while investigating the nature of dark energy with current and upcoming large-scale galaxy surveys.
