description: Cross-couplings between a massless spin-two field (described in the free limit by the Pauli-Fierz action) and an Abelian three-form gauge field in D=11 are investigated in the framework of the deformation theory based on local BRST cohomology. These consistent interactions are obtained on the grounds of smoothness in the coupling constant, locality, Lorentz covariance, Poincare invariance, and the presence of at most two derivatives in the interacting Lagrangian. Our results confirm the uniqueness of the eleven-dimensional interactions between a graviton and a three-form prescribed by General Relativity.

description: A measured solenoid is a laminated space endowed with a tranversal measure invariant by holonomy, as defined in arXiv:0910.2836. A measured solenoid immersed in a smooth manifold produces a closed current (known as generalized Ruelle-Sullivan current). Uniquely ergodic solenoids are those for which there is a unique (up to scalars) transversal measure. By the results in arXiv:0910.2913, for any smooth manifold, any real homology class is represented by a uniquely ergodic solenoid. In this paper, we prove that the currents associated to uniquely ergodic solenoids are dense in the space of closed currents, therefore proving the abundance of such objects.

description: We present a comparative study of the physical properties of a homogeneous sample of 144 Narrow line Seyfert 1 (NLSy1) and 117 Broad-line Seyfert 1 (BLSy1) galaxies. These two samples are in a similar luminosity and redshift range and have optical spectra available in the 16$^{th}$ data release of Sloan Digital Sky Survey (SDSS-DR16) and X-ray spectra in either XMM-NEWTON or ROSAT. Direct correlation analysis and a Principal Component Analysis (PCA) have been performed using ten observational and physical parameters obtained by fitting the optical spectra and the soft X-ray photon indices as another parameter. We confirm that the established correlations for the general quasar population hold for both types of galaxies in this sample despite significant differences in the physical properties. We characterize the sample also using the line shape parameters, namely the asymmetry and kurtosis indices. We find that the fraction of NLSy1 galaxies showing outflow signatures, characterized by blue asymmetries, is higher by a factor of about 3 compared to the corresponding fraction in BLSy1 galaxies. The presence of high iron content in the broad-line region of NLSy1 galaxies in conjunction with higher Eddington ratios can be the possible reason behind this phenomenon. We also explore the possibility of using asymmetry in the emission lines as a tracer of outflows in the inner regions of Active Galactic Nuclei. The PCA results point to the NLSy1 and BLSy1 galaxies occupying different parameter spaces, which challenges the notion that NLSy1 galaxies are a subclass of BLSy1 galaxies.

description: Buildings are crucial in climate mitigation due to their significant share in final energy consumption and GHG emissions. However, the sector decarbonisation has been slow to move. This study aims to identify key barriers to building decarbonisation and analyse policy instruments addressing these barriers. In addition, the study also briefly discussed the contribution of building decarbonisation to SDGs as enablers for taking up the decarbonisation measures.
Effectiveness of the modified "Diabetic teaching tool" in group instruction
Creators: name: Burke, Matilda
Publisher: name: University of British Columbia
Year: 2010

description: This experimental study was designed to determine if the modified "Diabetic Teaching Tool" was an effective tool for use in group instruction. The "Diabetic Teaching Tool" was developed for individual instruction and tested in an earlier study by Skelton. This study was conducted, aver a four-month period, at a large urban hospital during the regularly scheduled diabetic class. All patients who attended and who met the criteria of the study were asked to participate. A total of twenty-four subjects agreed to participate and their written consent was obtained. The first twelve subjects were assigned to the control group and received group instruction by means of the diabetic teaching program of the institution. The remaining twelve subjects were assigned to the experimental group and received group instruction by means of the modified "Diabetic Teaching Tool". Each patient was given a test of diabetic learning before commencement of the instruction and again two to seven days after completion of the instruction. A profile sheet was completed at the time of the administration of the posttest. The two groups of subjects were found to be highly similar when compared on the demographic and diabetic characteristics obtained from the profile sheet. The t-test was used to analyze the test results. No statistically significant difference between the two groups was found. Then the Pearson product-moment correlation coefficient was used to compare the test results and selected demographic and diabetic characteristics. The selected characteristics were age at testing, education, age at onset of diabetes, reason for current admission to hospital or visit to the doctor and the length of time since diagnosed. No significant relationship was found between the test results and these characteristics for the control group. The only characteristic to be significantly related to test results for the experimental subjects was the length of time since diagnosed. The final comparison was between the experimental subjects of this study and those of the study conducted by Skelton. The two groups of subjects were highly similar when compared on the demographic and diabetic characteristics. The mean score obtained on the subtests of the test of diabetic learning was similar for both groups. The study concludes with suggested implications, recommendations for changes in the test of diabetic learning and recommendations for further research.

description: We have constructed the first all-sky CMB temperature and polarization lensed maps based on a high-resolution cosmological N-body simulation, the Millennium Simulation (MS). We have exploited the lensing potential map obtained using a map-making procedure (Carbone et al. 2008) which integrates along the line-of-sight the MS dark matter distribution by stacking and randomizing the simulation boxes up to $z = 127$, and which semi-analytically supplies the large-scale power in the angular lensing potential that is not correctly sampled by the N-body simulation. The lensed sky has been obtained by properly modifying the latest version of the LensPix code (Lewis 2005) to account for the MS structures. We have also produced all-sky lensed maps of the so-called $ψ_E$ and $ψ_B$ potentials, which are directly related to the electric and magnetic types of polarization. The angular power spectra of the simulated lensed temperature and polarization maps agree well with semi-analytic estimates up to $l < 2500$, while on smaller scales we find a slight excess of power which we interpret as being due to non-linear clustering in the MS. We also observe how non-linear lensing power in the polarised CMB is transferred to large angular scales by suitably misaligned modes in the CMB and the lensing potential. This work is relevant in view of the future CMB probes, as a way to analyse the lensed sky and disentangle the contribution from primordial gravitational waves.

description: We present mid-infrared (MIR) observations of the Type II-plateau supernova (SN) 2004et, obtained with the {\it Spitzer Space Telescope} between days 64 and 1406 past explosion. Late-time optical spectra are also presented. For the period 300-795 days past explosion, we argue that the spectral energy distribution of SN 2004et comprises (a) a hot component due to emission from optically thick gas, as well as free-bound radiation, (b) a warm component due to newly formed, radioactively heated dust in the ejecta, and (c) a cold component due to an IR echo from the interstellar-medium dust of the host galaxy, NGC 6946. There may also have been a small contribution to the IR SED due to free-free emission from ionised gas in the ejecta. We reveal the first-ever spectroscopic evidence for silicate dust formed in the ejecta of a supernova. This is supported by our detection of a large, but progressively declining, mass of SiO. However, we conclude that the mass of directly detected ejecta dust grew to no more than a few times 10^(-4)Msun. We also provide evidence that the ejecta dust formed in comoving clumps of fixed size. We argue that, after about two years past explosion, the appearance of wide, box-shaped optical line profiles was due to the impact of the ejecta on the progenitor circumstellar medium and that the subsequent formation of a cool, dense shell was responsible for a later rise in the MIR flux. This study demonstrates the rich, multi-faceted ways in which a typical core-collapse supernova and its progenitor can produce and/or interact with dust grains. The work presented here adds to the growing number of studies which do not support the contention that SNe are responsible for the large mass of observed dust in high-redshift galaxies.

description: In previous work in undoped MFe2As2, partial drops in the resistivity indicative of traces of superconductivity have been observed in some samples of M=Ba (Tc ~ 20 K, up to 25% drop in resistivity) and M=Ca (Tc ~ 10 K, up to 45 % drop in resistivity.) A complete drop in the resistivity to 0, along with a finite fraction of Meissner flux expulsion, has been observed in M=Sr, Tc = 22 K. Using In-flux grown single crystal samples of undoped BaFe2As2, we find a complete drop in the resistivity to 0 in most samples beginning at Tc(onset) = 22.5 K. However, in contrast to the SrFe2As2 results, there is no measurable Meissner effect and no suppression of the resistive superconducting transition with annealing. The current sensitivity of the superconducting resistive transition in our samples of BaFe2As2 is quite strong, with an increase in the current density of a factor of 15 to ~ 1.5 A/cm2 not changing Tc(onset) but broadening the transition significantly and causing the resistivity to remain finite as T approaches 0. To investigate if this unusually low critical current is indicative of filamentary conduction lacking the apparent anisotropy seen in the critical magnetic field, Hc2, measurements of, e. g., the bulk superconductor Co-doped BaFe2As2, Hc2 was measured in both crystalline directions. These BaFe2As2 samples show Hc2(T) values in the ab-plane and along the c-axis comparable to those seen in BaFe2-xCoxAs2, which has a similar Tc. Since the lack of Tc suppression after annealing argues against strain-induced superconductivity as proposed for the other undoped MFe2As2 materials, another possible cause for the superconductivity in BaFe2As2 is discussed.

Year: 2025

description: The paper aims to create a feature extraction and classification system for certificates based on Optical Character Recognition (OCR) technology. The system seeks to automate the process of certificate classification and activity point assignment by extracting pertinent textual information such as student names, course titles, issuing organizations, and dates from scanned certificate images. Using sophisticated OCR algorithms, such as EasyOCR and OpenCV, the system processes images beforehand to improve the accuracy of text recognition. Then the extracted text is processed with natural language processing (NLP) for categorizing into pre-specified types like course completion, workshop attendance, and honors. This mechanized process significantly lessens human intervention and error involved in certificate validation processes, making it a scalable solution for academic institutions and organizations like KTU, MG University etc.

This will assure a higher landscape quality in comparison to the main roads of the adjoining valleys. The project also propose an ecological land settlement criterion for the surrounding rural areas. The ecological value should descend from the following aspects: hills areas are not menaced by the flood as river-side areas are; new settlements must grant highs energy-saving performances, reusable building materials and a very low visual impact, in order to respect the characteristics of the rural landscape. A competition procedure could be used to assign construction rights in order to select the plans that better respond to the ecological characteristics previously listed.

We report on the fabrication and characterization of superconducting flux qubits, readout dc SQUIDs, on-chip shunting capacitors, and high-quality coplanar waveguide resonators. Furthermore, we discuss the tunability and fundamental symmetry aspects inherent to all superconducting qubits, which can be regarded as artificial solid-state atoms. Comparing them to their natural counterparts, we discuss first and second-order energy shifts due to static control fields. Additionally, we present an intuitive derivation of the first- and second-order matrix elements for level transitions in the presence of a coherent microwave driving.

description: We investigated the possible cause-effect relation between the wiggling shape of two stellar jets, MHO 1502 and MHO 2147, and the potential binarity of the respective driving stars. We present high-angular-resolution H$_2$ (2.122 $μ$m) and K-band images obtained with the Gemini South Adaptive Optics Imager (GSAOI) and the Gemini Multi-conjugate Adaptive Optics System (GeMS). The profiles of the jets are depicted in detail by the H$_2$ images. We used K-band data to search for potential close companions to the previously suggested exciting sources, and used archive data to investigate these sources and the environments in which the jets are located. We also applied a model to reproduce the wiggling profiles of the jets. MHO~1502 is composed of a chain of knots delineating the wiggling jet, suggesting that the driving source emitted them in an intermittent manner. Our K-band image of the previously proposed exciting star, IRAC 18064, shows two sources separated by $\sim240$ AU, hinting at its binarity. However, as IRAC 18064 is located off the jet axis at $\sim2064$ AU, it is questionable as to whether this source is the true exciting star. Moreover, the orbital model centred on IRAC 18064 suggests a binary companion at a much greater distance ($\sim2200$ AU) than the nearby star (at $\sim$240 AU). On the other hand, the orbital model centred on the axis provides the best fits. Nevertheless, the precession model centred on the axis cannot be discarded, despite having larger residuals and $χ^2$. MHO 2147 displays an S-shaped gentle continuous emission in H$_2$. We identify two other jets in the field of MHO 2147: a previously reported quasi-perpendicular jet, MHO 2148, and a third jet adjacent to MHO 2147. The model that best fits the morphology of the MHO 2147 jet and that of its adjacent jet is precession. The exciting source of MHO 2147 may be a triple system.

description: We review and compare recent work on the properties of fluctuating interfaces between nematic and isotropic liquid-crystalline phases. Molecular dynamics and Monte Carlo simulations have been carried out for systems of ellipsoids and hard rods with aspect ratio 15:1, and the fluctuation spectrum of interface positions (the capillary wave spectrum) has been analyzed. In addition, the capillary wave spectrum has been calculated analytically within the Landau-de Gennes theory. The theory predicts that the interfacial fluctuations can be described in terms of a wave vector dependent interfacial tension, which is anisotropic at small wavelengths (stiff director regime) and becomes isotropic at large wavelengths (flexible director regime). After determining the elastic constants in the nematic phase, theory and simulation can be compared quantitatively. We obtain good agreement for the stiff director regime. The crossover to the flexible director regime is expected at wavelengths of the order of several thousand particle diameters, which was not accessible to our simulations.

description: The contribution of the AFOLU sector for achieving net zero by mid-century is critical and few countries will rely on the sector to achieve the goal of the Paris Agreement. However, the sector faces significant economic, political and structural barriers across all levels of governance. To address these and materialize the potential of the sector, far-reaching and comprehensive public policies and support are needed. This paper analyses the national policy frameworks of 10 countries where the AFOLU sector, in particular Forest, seem to be considered in their NDCs and will play a role for achieving net zero by mid-century. First, we identify general sectoral mitigation barriers, challenges and opportunities and analyse how these are manifested at national level, based on country case studies conducted or reviewed by national experts. Second, we consider if national policy frameworks are fit for purpose of the AFOLU sector to contribute to country LTS targets.

description: Eating disorders are severe mental health concerns that need to be studied further to gain more knowledge about how to treat them. This quantitative study aimed to explore the relationship between disordered eating, self-esteem, and sexual satisfaction in cisgender women ages 18-40 years old. No previous literature had found a relationship between all three factors. The research was conceptualized through a feminist theory perspective. It was hypothesized that disordered eating would have a negative relationship with self-esteem and sexual satisfaction. Another hypothesis was that self-esteem would have a negative relationship with sexual satisfaction and disordered eating. Both of the hypotheses were supported. Lower self-esteem was found to have a negative relationship with disordered eating and sexual satisfaction. Clinicians are encouraged to keep these results in mind when working with individuals with eating disorders to ensure they are providing the best care for clients.

description: We use an $N$-body+smoothed particle hydrodynamics simulation of an isolated barred galaxy to study the age dependence of bulge longitudinal proper motion ($μ_l$) rotation curves. We show that close to the minor axis ($|l| \sim 0^\circ$) the relatively young stars rotate more rapidly than the old stars, as found by Hubble Space Telescope in the Milky Way's (MW's) bulge. This behaviour would be expected also if the MW were unbarred. At larger $|l|$ a different behaviour emerges. Because younger stars trace a strong bar, their galactocentric radial motions dominate their $μ_l$ at $|l| \sim 6^\circ$, leading to a reversal in the sign of $\left< μ_l \right>$. This results in a rotation curve with forbidden velocities (negative $\left< μ_l \right>$ at positive longitudes, and positive $\left< μ_l \right>$ at negative longitudes). The old stars, instead, trace a much weaker bar and thus their kinematics are more axisymmetric, resulting in no forbidden velocities. We develop metrics of the difference in the $\left< μ_l \right>$ rotation curves of young and old stars, and forbidden velocities. We use these to predict the locations where rotation curve reversals can be observed by HST and the Vera Rubin Telescope. Such measurements would represent support for the amplitude of the bar being a continuous function of age, as predicted by kinematic fractionation, in which the bar strength variations are produced purely by differences in the random motions of stellar populations at bar formation.

Fostering Sense of Community and Healthy Communities: Exploring Participatory Planning Processes for Cultural Diversity in Aotearoa New Zealand

description: In the island nation of Aotearoa New Zealand, the reality of cultural diversity brought about by the history of migration and increased globalisation places more diverse demands on social and cultural frameworks. These diverse demands in relation to different cultures represent a range of community interests and needs, which participatory planning processes can respond to and draw out for representation in public open space planning and design, thereby promoting healthy, active, and equitable communities. It is also the community participation that is trying to create a higher sense of community and enhance health/well-being for a wider range of population and ethnicity. Society should not only accept and maintain this cultural difference; it is also necessary to effectively incorporate these different perspectives from multiple ethnic groups into the community participation process.
This research aims to investigate preferences for different participatory planning processes among New Zealand European, Māori, Chinese, and Pasifika community members, with the objective of identifying the most effective approaches. To achieve this, a series of focused discussions were conducted through independent focus groups representing each ethnic group. Through these discussions, the study explored participants' experiences with participatory planning processes and their outcomes, while also examining the influence of cultural backgrounds on their preferred methods of community participation. This focus on equity ensures that health-promoting strategies are tailored to the specific cultural contexts, promoting fairness in the distribution of resources and opportunities for health and well-being. By analysing and discussing the similarities and differences in preferences across the different ethnic groups, this research aims to provide insights into effective strategies for encouraging a sense of community in Aotearoa New Zealand.
This research will shed light on the critical role of participatory planning processes in creating healthier, more active, and equitable communities. It will emphasize the need to embrace cultural diversity and effectively incorporate the perspectives of multiple ethnic groups into community participation processes. Ultimately, the study's findings will offer practical guidance for policymakers, planners, and practitioners in fostering healthy, active, equitable, and vital communities as integral components of government policies and community development practices.

description: Modern statistical applications often involve minimizing an objective function that may be nonsmooth and/or nonconvex. This paper focuses on a broad Bregman-surrogate algorithm framework including the local linear approximation, mirror descent, iterative thresholding, DC programming and many others as particular instances. The recharacterization via generalized Bregman functions enables us to construct suitable error measures and establish global convergence rates for nonconvex and nonsmooth objectives in possibly high dimensions. For sparse learning problems with a composite objective, under some regularity conditions, the obtained estimators as the surrogate's fixed points, though not necessarily local minimizers, enjoy provable statistical guarantees, and the sequence of iterates can be shown to approach the statistical truth within the desired accuracy geometrically fast. The paper also studies how to design adaptive momentum based accelerations without assuming convexity or smoothness by carefully controlling stepsize and relaxation parameters.
The major soils of the Tofino area of Vancouver Island and implications for land use planning and management

description: 'The soils resource in the Tofino area of Vancouver Island is considered for land-use planning and management purposes. This was done by completing a series of four studies. The first study describes the study area by looking at those components which were considered to have a major impact on the function of the soils in the landscape. This included geology (bedrock and surficial), soil morphology, depth to water table, vegetation, climate and water quality. The soils exhibit a range of soil development from very little to strongly expressed genetic characteristics including cemented horizons. The presence of many lithologic discontinuities confirms a complex mode of material deposition in the area. The second study is concerned with the physical, chemical and mineralogical properties of the soils. Soil genesis is also discussed. The analyses show a wide range of textures in the soils and varifies the presence of lithologic discontinuities. Pedo-genic processes have changed the structure in some soils by aggregating the Fe and Al oxides into larger sized particles. The soils are low in natural fertility with nutrient cycling occurring primarily in the organic horizons or above restricting layers in the mineral horizons if these are near the surface. Vermiculite is the dominant clay mineral in the surface mineral horizons indicating a weathering environment of moderate intensity. The third study discusses the characteristics and genesis of some placic horizons (thin pans) which have developed in some soils in sand deposits. These horizons exhibit considerable variation in morphology and chemical composition. The primary cementing materials are organic matter (mainly fulvic acid), and Pe which is present as either inorganic amorphous or organically complexed Fe. The morphological characteristics and stability of the placic horizons are dependent upon the amount of OM present and the form in which the Fe occurs. The genesis of these pans is initiated at lithologic discontinuities under differential redox conditions. Diffusion is active in material transport with the pan acting as a template upon which the material is precipitated. The fourth study is an assessment of-the soils for land-use planning and management purposes. Emphasis is given to the identification of processes which control the function of the soils both internally and externally. The soils are grouped into three categories characteristic of the dominant control. The categories are; landscape components, inherent characteristics and genetic features.
Superprotected n-point correlation functions of local operators in N=4 super Yang-Mills

description: In this paper we study the n-point correlation functions of two different families of local gauge invariant operators in N=4 supersymmetric Yang-Mills theory. The main idea is to consider the correlation functions of operators which all share a number of supersymmetries irrespective of their relative locations. We achieve this by equipping the operators with explicit space-time dependence. We provide evidence by different methods that these n-point correlators do not receive quantum corrections in perturbation theory and are hence given exactly by their tree-level result. The arguments rely on explicit checks for general four-point correlators, some five-point and six-point correlators and a more abstract calculation based on a novel topological twisting of N=4 supersymmetric Yang-Mills theory.

Rational recreation : the social control of leisure and popular culture in Victorian England, 1830-1885
Creators: name: Bailey, Peter Cecil
Publisher: name: University of British Columbia
Year: 2010

description: The thesis examines the transformation of popular leisure in mid-nineteenth century England, with special reference to the various schemes of 'rational recreation' whereby social reformers attempted to control the content and direction of cultural change. The movement aimed to improve the conduct of working-class leisure in such a way as to promote moral progress and class reconciliation. Through the philanthropic -provision of new recreational amenities and the fraternal encouragement of middle-class superintendants, the workers were to be immunised against the corruptions of their own culture and instructed in the social values and disciplines of their betters. After giving account of the state of popular recreations and the genesis of the reform design in the 1830s and-'40s, the thesis examines the developing concept and performance of rational recreation in the context of the rapidly expanding new leisure world which overtook Victorian society from the mid-century on. Following a consideration of the changing practice and rationale of leisure among the middle classes and the implications for social reform, the thesis looks at the increasing activity and debate in reform circles in these years, and examines the influence of rational recreation on working-class culture in three specific areas: the reform experiment of the Working Men's Club movement; the promotion of organised games and the new athleticism; and the emergent mass entertainment industry of the music halls. The study is based on extensive reading in contemporary periodicals, the specialist press, government reports and social commentaries on working-class life, and draws on local evidence from Bolton, Lancashire. Rational recreation enjoyed some success, but working-class leisure retained a strong class identity and resisted any comprehensive conversion to the bourgeois value system. While recognising that popular recreations increasingly conformed to the patterns required by a maturing urban industrial society, the thesis concludes that such adjustments owed more to an internal process of largely autonomous adaptation and growth in working-class culture than to the direct influence of reformers who were, in any case, ill-equipped to overcome the social distance between the classes which remained a pronounced feature of English leisure.

description: In dissipative ordinary differential equation systems different time scales cause anisotropic phase volume contraction along solution trajectories. Model reduction methods exploit this for simplifying chemical kinetics via a time scale separation into fast and slow modes. The aim is to approximate the system dynamics with a dimension-reduced model after eliminating the fast modes by enslaving them to the slow ones via computation of a slow attracting manifold. We present a novel method for computing approximations of such manifolds using trajectory-based optimization. We discuss Riemannian geometry concepts as a basis for suitable optimization criteria characterizing trajectories near slow attracting manifolds and thus provide insight into fundamental geometric properties of multiple time scale chemical kinetics. The optimization criteria correspond to a suitable mathematical formulation of "minimal relaxation" of chemical forces along reaction trajectories under given constraints. We present various geometrically motivated criteria and the results of their application to three test case reaction mechanisms serving as examples. We demonstrate that accurate numerical approximations of slow invariant manifolds can be obtained.

description: We explain the PAMELA positron excess and the PPB-BETS/ATIC e+ + e- data using a simple two component dark matter model (2DM). The two particle species in the dark matter sector are assumed to be in thermal equilibrium in the early universe. While one particle is stable and is the present day dark matter, the second one is metastable and decays after the universe is 10^-8 s old. In this model it is simple to accommodate the large boost factors required to explain the PAMELA positron excess without the need for large spikes in the local dark matter density. We provide the constraints on the parameters of the model and comment on possible signals at future colliders.

description: The Atacama Large Millimeter/submillimeter Array (ALMA) is an international radio telescope under construction in the Atacama Desert of northern Chile. ALMA is situated on a dry site at 5000 m elevation, allowing excellent atmospheric transmission over the instrument wavelength range of 0.3 to 10 mm. ALMA will consist of two arrays of high-precision antennas. One, of up to 64 12-m diameter antennas, is reconfigurable in multiple patterns ranging in size from 150 meters up to ~15 km. A second array is comprised of a set of four 12-m and twelve 7-m antennas operating in one of two closely packed configurations ~50 m in diameter. The instrument will provide both interferometric and total-power astronomical information on atomic, molecular and ionized gas and dust in the solar system, our Galaxy, and the nearby to high-redshift universe. In this paper we outline the scientific drivers, technical challenges and planned progress of ALMA.
