description: Design studios play an important role in training future architects and designers, representing a key space for experimentation and creative practice in the education of architecture, landscape architecture and interior architecture students. Unlike other courses, design studios confront students with the concrete practical aspects of the design process, along with the more abstract poetic experiences of designing. This combination of practice with theory introduces students to the concept of creativity and creative design processes. While conceptually exciting, student engagement often comes with feelings of vulnerability and fear of ‘exposure’ that design practice brings, preventing them from experimentation. This paper explores various experiments designed to foster trust to aid in students’ engagement in creative practices within studios. Several assignments follow where techniques are specifically designed to encourage creativity in the context of the architectural design studio. The paper further examines how architectural studio style teaching can foster a way of creating as well as researching through design and can provide a forum for both the sharing of knowledge as well as communication and collaboration between a wide range of stakeholders.

description: Magnetic properties of Fe, Co, and Ni at finite temperatures have been investigated on the basis of the first-principles dynamical CPA (Coherent Potential Approximation) combined with the LDA (Local Density Approximation) + $U$ Hamiltonian in the Tight-Binding Linear Muffintin Orbital (TB-LMTO) representation. The Hamiltonian includes the transverse spin fluctuation terms. Numerical calculations have been performed within the harmonic approximation with 4th-order dynamical corrections. Calculated single-particle densities of states in the ferromagnetic state indicate that the dynamical effects reduce the exchange splitting, suppress the band width of the quasi-particle state, and causes incoherent excitations corresponding the 6 eV satellites. Results of the magnetization vs temperature curves, paramagnetic spin susceptibilities, and the amplitudes of local moments are presented. Calculated Curie temperatures ($T_{\rm C}$) are reported to be 1930K for Fe, 2550K for Co, and 620K for Ni; $T_{\rm C}$ for Fe and Co are overestimated by a factor of 1.8, while $T_{\rm C}$ in Ni agrees with the experimental result. Effective Bohr magneton numbers calculated from the inverse susceptibilities are 3.0 $μ_{\rm B}$ (Fe), 3.0 $μ_{\rm B}$ (Co), and 1.6 $μ_{\rm B}$ (Ni), being in agreement with the experimental ones. Overestimate of $T_{\rm C}$ in Fe and Co is attributed to the neglects of the higher-order dynamical effects as well as the magnetic short range order.

Students' social experiences through inventing games

Publisher: name: University of British Columbia
Year: 2014

description: Although small group work is often used as a pedagogical tool in physical education (PE), little is known about factors that affect the social experiences of the students, as reported from their own perspective as they work in a small group setting. The purpose of this research was to enable a number of grade eight male students to share their lived social experiences as they engaged in an Inventing Games (IG) unit. This study was framed within a wider study, conducted by the principal investigator (Dr. Joy Butler), and initiated under the auspices of a Social Sciences and Humanities Research Council grant in 2009. The goal of the larger project was to investigate how IG, an educational program in Physical Education (PE), can support the development and awareness of principles of ethical actions as they become manifest in situated and collaborative learning contexts (Butler, Hopper & Davis, 2009). My study focused on one group within my PE class. The students in the focus group shared their social experiences through journals and interviews over the course of an eight-session unit. I used a phenomenological approach to analyze the data and in the process I identified four themes: (a) inclusion within the decision-making process, (b) acknowledging ideas, (c) student-selected team selection process, and (d) relating the IG experience to “real- life.” These four themes became apparent through a process of applying a complexity thinking lens to examine the ways in which the focus group could be understood in terms of a complex adaptive system, and to identify the ways in which the conditions of complex emergence were established to allow for emergent learning within the group. This study has had an impact on my teaching practice and, in turn, could have implications for the wider PE community. For example, on the basis of valuable insights gained from the students in the focus group, I have achieved a better understanding overall of the social experiences of students as they engage in PE, and am consequently better equipped to look out for hidden negative social experiences that can occur in small group settings.

description: Gamow-Teller strength distributions, beta-decay half-lives, and beta-delayed neutron emission are investigated in neutron-rich Zr and Mo isotopes within a deformed quasiparticle random-phase approximation. The approach is based on a self-consistent Skyrme Hartree-Fock mean field with pairing correlations and residual separable particle-hole and particle-particle forces. Comparison with recent measurements of half-lives stresses the important role that nuclear deformation plays in the description of beta-decay properties in this mass region.

description: The carbon footprint of households is a significant contribution to global greenhouse gas emissions, accounting for 24% of total emissions. As a result, it is critical to quantify a household's carbon footprint in order to reduce it over time. One of the best ways to measure carbon emitted from various sectors of the economy, including household daily activities, is to calculate a country's carbon footprint (CF). This study statistically examined the magnitude of households’ carbon footprints and their relationships with household daily activities and certain socio-economic demographic variables in Malaysia. Results revealed that the average household carbon footprint amounted to 11.76 t-CO2. The average also showed that the primary carbon footprint, 7.02 t-CO2 or 59.69% was higher compared to the secondary carbon footprint which was 4.73 t- CO2 or 40.22% and assessment revealed significant differences among household types. The largest carbon footprint was evident in a medium-high cost urban area, estimated at 20.14 t-CO2, while the carbon footprint found in a rural area was 9.58 t-CO2. In the latter, the primary carbon footprint was almost double the figure of 5.84 t-CO2 (61%) than the secondary carbon footprint of 3.73 t-CO2 (39%). The study reveals a higher carbon footprint in urban areas compared to rural ones depicting the effects of urbanisation and urban sprawl on household lifestyles and carbon footprints. Despite some limitations, the findings of this study will help policymakers design and implement stronger policies that enforce low-carbon activities and energy-saving goods and services in order to reduce urban Malaysia's carbon footprint dramatically.

description: In the functional approach to quantum chromodynamics, the properties of hadronic bound states are accessible via covariant integral equations, e.g. the Bethe-Salpeter equations for mesons. In particular, one has to deal with linear, homogeneous integral equations which, in sophisticated model setups, use numerical representations of the solutions of other integral equations as part of their input. Analogously, inhomogeneous equations can be constructed to obtain off-shell information in addition to bound-state masses and other properties obtained from the covariant analogue to a wave function of the bound state. These can be solved very efficiently using well-known matrix algorithms for eigenvalues (in the homogeneous case) and the solution of linear systems (in the inhomogeneous case). We demonstrate this by solving the homogeneous and inhomogeneous Bethe-Salpeter equations and find, e.g. that for the calculation of the mass spectrum it is more efficient to use the inhomogeneous equation. This is valuable insight, in particular for the study of baryons in a three-quark setup and more involved systems.

description: Context: Cosmic rays are present in almost all phases of the ISM. PAHs and cosmic rays represent an abundant and ubiquitous component of the interstellar medium. However, the interaction between them has never before been fully investigated. Aims: To study the effects of cosmic ray ion (H, He, CNO and Fe-Co-Ni) and electron bombardment of PAHs in galactic and extragalactic environments. Methods: We calculate the nuclear and electronic interactions for collisions between PAHs and cosmic ray ions and electrons with energies between 5 MeV/nucleon and 10 GeV, above the threshold for carbon atom loss, in normal galaxies, starburst galaxies and cooling flow galaxy clusters. Results: The timescale for PAH destruction by cosmic ray ions depends on the electronic excitation energy Eo and on the amount of energy available for dissociation. Small PAHs are destroyed faster, with He and the CNO group being the more effective projectiles. For electron collisions, the lifetime is independent of the PAH size and varies with the threshold energy To. Conclusions: Cosmic rays process the PAHs in diffuse clouds, where the destruction due to interstellar shocks is less efficient. In the hot gas filling galactic halos, outflows of starburst galaxies and intra-cluster medium, PAH destruction is dominated by collisions with thermal ions and electrons, but this mechanism is ineffective if the molecules are in denser cloudlets and isolated from the hot gas. Cosmic rays can access the denser clouds and together with X-rays will set the lifetime of those protected PAHs. This limits the use of PAHs as a`dye' for tracing the presence of cold entrained material.

description: We overview a holographic QCD based on the D4-D8 string theory model, with emphasis on baryons and nucleon-meson interactions thereof. Baryons are realized as holographic images of Skyrmions, but with much qualitative changes. This allows us to derive, without adjustable parameters, couplings of baryons to the entire tower of spin one mesons and also to pseudoscalar mesons. We find some surprisingly good match against empirical values for nucleons, in particular. Tensor couplings to all axial-vectors and iso-singlet vectors all vanish, while, for $ρ$ mesons, tensor couplings are found to be dominant. We close with various cautionary comments and speculations.

description: The temperature fluctuations and polarization of the Cosmic Microwave Background (CMB) are now a well-known probe of the Universe at an infant age of 400,000 years. During the transit to us from the surface of last scattering, the CMB photons are expected to undergo modifications induced by the intervening large-scale structure. Among the expected secondary effects is the weak gravitational lensing of the CMB by the foreground dark matter distribution. We derive a quadratic estimator that uses the non-Gaussianities generated by the lensing effect at the four-point function level to extract the power spectrum of lensing potential fluctuations integrated out to z ~ 1100 with peak contributions from potential fluctuations at z of 2 to 3. Using WMAP 7-year temperature maps, we report the first direct constraints of this lensing potential power spectrum and find that it has an amplitude of A_L = 0.96 +/- 0.60, 1.06 +/- 0.69 and 0.97 +/- 0.47 using the W, V and W+V bands, respectively.

description: The objective of this study is to analyse the rationales, challenges and prospects of Dhaka City being split up, for the purposes of creating a sustainable city grounded in relevant theories and widely used and accepted standards. An assessment of Dhaka being divided in accordance with the concept of City Development Strategies reveals considerable deficiencies in most aspects of public goods and services provisions. Whilst splitting Dhaka into separate sections supports the “World City Hypothesis” it is not without criticisms, for instance those raised by urban planners, experts and politicians. The lack of resources and oversight to address those deficiencies and problems and the administrative, allocative, economic and social inefficiencies makes it very difficult for Dhaka’s authorities to achieve sustainable urbanisation. Therefore, appropriate strategies must be implemented by government to resolve these problems, inefficiencies and mismanagement in order for the city to be liveable sustainable.

description: We propose a multi-moment method for one-dimensional hyperbolic equations with smooth coefficient and piecewise constant coefficient. The method is entirely based on the backward characteristic method and uses the solution and its derivative as unknowns and cubic Hermite interpolation for each computational cell. The exact update formula for solution and its derivative is derived and used for an efficient time integration. At points of discontinuity of wave speed we define a piecewise cubic Hermite interpolation based on immersed interface method. The method is extended to the one-dimensional Maxwell's equations with variable material properties.

description: We review a theoretical scenario for the origin of the spin-glass phase of underdoped cuprate materials. In particular it is shown how disorder in a correlated d-wave superconductor generates a magnetic phase by inducing local droplets of antiferromagnetic order which eventually merge and form a quasi-long range ordered state. When correlations are sufficiently strong, disorder is unimportant for the generation of static magnetism but plays an additional role of pinning disordered stripe configurations. We calculate the spin excitations in a disordered spin-density wave phase, and show how disorder and/or applied magnetic fields lead to a slowing down of the dynamical spin fluctuations in agreement with neutron scattering and muon spin rotation (muSR) experiments.

description: We present spatially resolved integral field spectroscopic K-band data at a resolution of 0.13" (60pc) and interferometric CO(2-1) line observations of the prototypical merging system NGC6240. Despite the clear rotational signature, the stellar kinematics in the two nuclei are dominated by dispersion. We use Jeans modelling to derive the masses and the mass-to-light ratios of the nuclei. Combining the luminosities with the spatially resolved Br-gamma equivalent width shows that only 1/3 of the K-band continuum from the nuclei is associated with the most recent star forming episode; and that less than 30% of the system's bolometric luminosity and only 9% of its stellar mass is due to this starburst. The star formation properties, calculated from typical merger star formation histories, demonstrate the impact of different assumptions about the star formation history. The properties of the nuclei, and the existence of a prominent old stellar population, indicate that the nuclei are remnants of the progenitor galaxies' bulges.

description: Predicting the sustainability of a business is crucial to prevent financial losses among shareholders and investors. This study attempts to evaluate the Altman model for predicting corporate failure in distressed and non-distressed Malaysian companies based on the data of financially troubled companies which are classified as Practice Note 17 (PN17) and matching similar non-PN17 companies during the period 2013 to 2017. This study utilizes panel ordinal and panel random effects regressions. Findings show that the liquidity, profitability, leverage, solvency, and efficiency ratios are negatively significantly associated with corporate failure and bankruptcy. The leverage ratio is determined to be the strongest indicator of bankruptcy, followed by profitability, liquidity, solvency, and efficiency ratios. The findings will help companies’ management bodies implement suitable strategies to prevent further financial leakage, thereby ensuring continuous and sustainable return on investment and profits for investors and shareholders.

description: We measure black hole masses for 71 BL Lac objects from the Sloan Digital Sky Survey with redshifts out to z~0.4. We perform spectral decompositions of their nuclei from their host galaxies and measure their stellar velocity dispersions. Black hole masses are then derived from the black hole mass - stellar velocity dispersion relation. We find BL Lac objects host black holes of similar masses, ~10^{8.5} M_sun, with a dispersion of 0.4 dex, similar to the uncertainties on each black hole measurement. Therefore, all BL Lac objects in our sample have the same indistinguishable black hole mass. These 71 BL Lac objects follow the black hole mass - bulge luminosity relation, and their narrow range of host galaxy luminosities confirm previous claims that BL Lac host galaxies can be treated as standard candles. We conclude that the observed diversity in the shapes of BL Lac object spectral energy distributions is not strongly driven by black hole mass or host galaxy properties.

Michigan Womyn's Music Festival : place making and the queer persistence of feminism
Creators: name: Rowe, Carolyn Joyce
Publisher: name: University of British Columbia
Year: 2014

description: This dissertation research is designed to advance knowledge concerning contemporary conceptions of sexual citizenship, queer history and the context and performative nature of feminism during a time of “post-feminism” (Faludi, 1991; Fraser, 2009; McRobbie, 2004). I investigate feminism as it is enacted at the Michigan Womyn‘s Music Festival (hereafter referred to as the Festival). The Festival is an event that grew out of the second wave feminist movement in the 1960s and 1970s. It has survived decades of liberation movements, identity politics and related political struggles, threats from the religious right, transsexual inclusion/exclusion debates and so on. Unlike many of the feminist events that closed their doors in the 80s and 90s (Case, 1996) over the last 35 years this festival has grown into one of the oldest and largest lesbian feminist gatherings in the world (Cvetkovich and Wahng, 2001; Morris, 1999; Ryan, 1992; Taylor and Rupp, 1993). Since the mid-1980s, discussion about the “end of feminism” and what post-feminism means has increased (Faludi, 1991; Fraser, 2009; Jones, 1994; McRobbie, 2009; Modleski, 1991). Post-feminism sometimes refers to a new kind of anti-feminist sentiment, one that differs from the backlash faced by feminists in the 1970s and 1980s. Post-feminist discourse can imply that equality has been achieved and that feminists can now focus on something else. Within the pages of this dissertation, the avenue of study I engage in investigates the convergence of second-wave feminism (Daly, 1978; Dworkin, 2002; MacKinnon, 1989; Millet, 1970) in a post-feminist time. What does it mean to engage in various feminist identity practices whose time is past? How do the lived embodiments of race, gender difference, sexual alterity, and variations of bodily capacity structure the time and timing of particular collectivities? This project’s major animating question asks, then: How does feminism persist in a time of post-feminism?
The Discovery of a Strong Magnetic Field and Co-rotating Magnetosphere in the Helium-weak Star HD 176582

description: We report the detection of a strong, reversing magnetic field and variable H-alpha emission in the bright helium-weak star HD 176582 (HR 7185). Spectrum, magnetic and photometric variability of the star are all consistent with a precisely determined period of 1.5819840 +/- 0.0000030 days which we assume to be the rotation period of the star. From the magnetic field curve, and assuming a simple dipolar field geometry, we derive a polar field strength of approximately 7 kG and a lower limit of 52 degrees for the inclination of the rotation axis. However, based on the behaviour of the H-alpha emission we adopt a large inclination angle of 85 degrees and this leads to a large magnetic obliquity of 77 degrees. The H-alpha emission arises from two distinct regions located at the intersections of the magnetic and rotation equators and which corotate with the star at a distance of about 3.5 R* above its surface. We estimate that the emitting regions have radial and meridional sizes on the order of 2 R* and azimuthal extents (perpendicular to the magnetic equator) of less than approximately 0.6 R*. HD 176582 therefore appears to show many of the cool magnetospheric phenomena as that displayed by other magnetic helium-weak and helium-strong stars such as the prototypical helium-strong star sigma Ori E. The observations are consistent with current models of magnetically confined winds and rigidly-rotating magnetospheres for magnetic Bp stars.

It is realized in a usual two-qubit interferometry with local filtering. Proper filtering operation for the maximal distillation of the state is achieved, by erasing single-qubit interference, and then the concurrence of the state is determined directly from the visibilities of two-qubit interference. We compare the scheme with full state tomography.

Attenuation of shear sound waves in jammed solids

Publisher: name: arXiv

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)
subject: FOS: Physical sciences

description: We study the attenuation of long-wavelength shear sound waves propagating through model jammed packings of frictionless soft spheres interacting with repulsive springs. The elastic attenuation coefficient, $α(ω)$, of transverse phonons of low frequency, $ω$, exhibits power law scaling as the packing fraction $ϕ$ is lowered towards $ϕ_c$, the critical packing fraction below which rigidity is lost. The elastic attenuation coefficient is inversely proportional to the scattering mean free path and follows Rayleigh law with $α(ω)\sim ω^4 (ϕ- ϕ_c)^{-5/2}$ for $ω$ much less than $ω^* \sim (ϕ- ϕ_c)^{1/2}$, the characteristic frequency scale above which the energy diffusivity and density of states plateau. This scaling of the attenuation coefficient, consistent with numerics, is obtained by assuming that a jammed packing can be viewed as a mosaic composed of domains whose characteristic size $\ell^ * \sim (ϕ-ϕ_c) ^{-1/2}$ diverges at the transition.

description: Currently, nurses’ job performance in Nigeria’s public healthcare system has been called into question and is under more pressure due to the current global COVID-19 pandemic. In enhancing the effectiveness, efficiency and promptness of Nigeria’s public healthcare service delivery, this study seeks to explore how work engagement could play a key role in explaining the influence of organisational commitment on nurses’ job performance. A survey-based questionnaire, using a simple random technique was employed to collect data from 406 nurses working in public hospitals in Kaduna State, Nigeria. The data were analysed employing the Partial Least Squares-Structural Equation Model (PLS-SEM). Results demonstrate that affective and normative commitment wield positive significant effects on nurses’ job performance, while work engagement significantly mediates affective commitment, normative commitment and nurses’ job performance relationships. Consequently, this study recommends that the management of Nigeria’s public healthcare system and its policymakers should improve the commitment level of nurses through work engagement with a view to enhancing how well they do their job. This study benefits all the relevant stakeholders of Nigeria’s public healthcare system

description: We investigate periodic diffeomorphisms of non-compact aspherical manifolds (and orbifolds) and describe a class of spaces that have no homotopically trivial periodic diffeomorphisms. Prominent examples are moduli spaces of curves and aspherical locally symmetric spaces with non-vanishing Euler characteristic. In the irreducible locally symmetric case, we show that no complete metric has more symmetry than the locally symmetric metric. In the moduli space case, we build on work of Farb and Weinberger and prove an analogue of Royden's theorem for complete finite volume metrics.

description: The COVID-19 pandemic has emerged as one of the deadliest infectious diseases on the planet. Millions of people and businesses have been placed in lockdown where the main aim is to stop the spread of the virus. As an extreme phenomenon, the lockdown has triggered a global economic shock at an alarming pace, conveying sharp recessions for many countries. In the meantime, the lockdowns caused by the COVID-19 pandemic have drastically changed energy consumption patterns and reduced CO2 emissions throughout the world. Recent data released by the International Monetary Fund and International Energy Agency for 2020 further forecast that emissions will rebound in 2021. Still, the full impact of COVID-19 in terms of how long the crisis will be and how the consumption pattern of energy and the associated levels of CO2 emissions will be affected are unclear. This review aims to steer policymakers and governments of nations toward a better direction by providing a broad and convincing overview on the observed and likely impacts of the pandemic of COVID-19 on the world economy, world energy demand, and world energy-related CO2 emissions that may well emerge in the next few years. Indeed, given that immediate policy responses are required with equal urgency to address three things—pandemic, economic downturn, and climate crisis. This study outlines policy suggestions that can be used during these uncertain times as a guide.
Discrete element modeling of direct simple shear response of granular soils and model validation using laboratory tests
Creators: name: Dabeet, Antone
Publisher: name: University of British Columbia

description: The direct simple shear (DSS) device is one of the most commonly used laboratory testing tools to characterize the shear behavior of soils. In the Norwegian Geotechnical Institute (NGI) version of the DSS test, where a cylindrical soil specimen is confined by a wire-reinforced membrane, only normal and shear stresses on the horizontal planes are measured. The knowledge of these stresses alone does not provide adequate information to calculate friction angles for use in geotechnical design. Further, the absence of complementary shear stresses at the soil-membrane interface causes stress non-uniformities within DSS specimens, which makes the task of interpreting DSS testing results even more difficult. With the recent advances in computers, it is now possible to model soil in a realistic manner as a collection of particles using the discrete element method (DEM). With this background, a DEM model of a cylindrical DSS specimen was developed to provide insight on the state of stress and strain in DSS specimens. A laboratory DSS testing program was undertaken on glass beads as part of this study. The results of the glass beads tests were used for comparison with the DEM model results. Further, free-form sensors (paper-thin flexible pressure sensors mounted on the reinforced part of the DSS membrane) were used to measure lateral stresses acting on reconstituted Fraser River silt specimens. It was shown that: i) the adopted DEM modeling approach is effective in capturing the salient characteristics of the DSS behavior of the tested glass beads; ii) during the shearing phase, the distribution of shear strains across the specimen is more uniform at lower shear strain levels; iii) significant stress non-uniformities during shearing are limited to a narrow zone of about two particles diameter near the lateral boundaries, while stresses at central specimen locations are relatively more uniform (i.e. most representative of “ideal” simple shear conditions); and iv) at large shear strains, the horizontal plane becomes the plane of maximum obliquity, and the friction angle calculated using the stress state on the horizontal plane is a good approximation to the mobilized friction angle at such strain levels.

description: Recent proposals of topological flat band (TFB) models have provided a new route to realize the fractional quantum Hall effect (FQHE) without Landau levels. We study hard-core bosons with short-range interactions in two representative TFB models, one of which is the well known Haldane model (but with different parameters). We demonstrate that FQHE states emerge with signatures of even number of quasi-degenerate ground states on a torus and a robust spectrum gap separating these states from higher energy spectrum. We also establish quantum phase diagrams for the filling factor 1/2 and illustrate quantum phase transitions to other competing symmetry-breaking phases.

Quantification of cooling channel heat transfer in low pressure die casting
Creators: name: Moayedinia, Sara
Publisher: name: University of British Columbia
Year: 2014

description: The focus of this project is to develop a methodology to quantitatively describe the heat transfer in the cooling channels of the low-pressure die casting process, which is the dominant commercial technology for the production of aluminum automotive wheels, and to successfully implement the methodology in a numerical model of the casting process. Towards this goal, an algorithm capable of calculating heat transfer coefficient (HTC) based on process parameters and surface temperature within the cooling channel is developed. The algorithm was implemented in the form of a user-defined subroutine in a 3-D thermal model of the Low Pressure Die Casting (LPDC) process developed in the commercial finite element analysis package in ABAQUS. The cooling channel HTC’s are often input into thermal models as an average constant value derived based on trial-and-error. The trial-and-error process to obtain the HTCs in the cooling channel involves, prescribing a trial set of HTC values and comparing the results of the casting simulation with thermocouple measurements. The trial cooling channel HTCs are then adjusted until a reasonable fit to the temperature measurements are achieved. The trial-and-error process is generally time consuming and does not accurately describe the physical phenomenon occurring in the cooling channel during casting. The constant cooling channel HTCs obtained through the trial-and-error process are tuned to a given set of operating conditions, compromising the utility and generality of the model. To provide data necessary for model validation, casting plant trials were performed at Canadian Autoparts Toyota Inc. in Delta, British Columbia. The trials included temperature measurements at pre-determined locations within the top, side and bottom dies. The validity of HTC calculations have been assessed by comparing the predicted temperature history of the subroutine-based model with the measured thermocouple data collected during the casting cycle and also comparing the model predictions with the base-case model with constant cooling channel HTC.

description: The carbon-to-oxygen ratio (C/O) in a planet provides critical information about its primordial origins and subsequent evolution. A primordial C/O greater than 0.8 causes a carbide-dominated interior as opposed to a silicate-dominated composition as found on Earth, and the atmospheres can also differ from those in the Solar System. The solar C/O is 0.54. Here we report an analysis of dayside multi-wavelength photometry of the transiting hot-Jupiter WASP-12b that reveals C/O >= 1 in its atmosphere. The atmosphere is abundant in CO. It is depleted in water vapor and enhanced in methane by over two orders of magnitude each compared to a solar-abundance chemical-equilibrium model at the expected temperatures. We also find that the extremely irradiated atmosphere (T > 2,500 K) of WASP-12b lacks a prominent thermal inversion, or a stratosphere, and has very efficient day- night energy circulation. The absence of a strong thermal inversion is in stark contrast to theoretical predictions for the most highly irradiated hot-Jupiter atmospheres.
