description: Context. NGC 1851 is one of several globular clusters for which multiple stellar populations of the subgiant branch have been clearly identified and a difference in metallicity detected. A crucial piece of information on the formation history of this cluster can be provided by the sum of A(C+N+O) abundances. However, these values have lacked a general consensus thus far. The separation of the subgiant branch can be based on age and/or A(C+N+O) abundance differences. Aims. Our main aim was to determine carbon, nitrogen, and oxygen abundances for evolved giants in the globular cluster NGC1851 in order to check whether or not the double populations of stars are coeval. Methods. High-resolution spectra, observed with the FLAMES-UVES spectrograph on the ESO VLT telescope, were analysed using a differential model atmosphere method. Results. We provide abundances of up to 29 chemical elements for a sample of 45 giants in NGC 1851. The investigated stars can be separated into two populations with a difference of 0.07 dex in the mean metallicity, 0.3 dex in the mean C/N, and 0.35 dex in the mean s-process dominated element-to-iron abundance ratios [s/Fe]. No significant difference was determined in the mean values of A(C+N+O) as well as in abundance to iron ratios of carbon, alpha- and iron-peak-elements, and of europium. Conclusions. As the averaged A(C+N+O) values between the two populations do not differ, additional evidence is given that NGC 1851 is composed of two clusters, the metal-rich cluster being by about 0.6 Gyr older than the metal-poor one. A global overview of NGC 1851 properties and the detailed abundances of chemical elements favour its formation in a dwarf spheroidal galaxy that was accreted by the Milky Way.

description: Online communities, like Wikipedia, produce valuable public information goods. Whereas some of these communities require would-be contributors to create accounts, many do not. Does this requirement catalyze cooperation or inhibit participation? Prior research provides divergent predictions but little causal evidence. We conduct an empirical test using longitudinal data from 136 natural experiments where would-be contributors to wikis were suddenly required to log in to contribute. Requiring accounts leads to a small increase in account creation, but reduces both high- and low-quality contributions from registered and unregistered participants. Although the change deters a large portion of low-quality participation, the vast majority of deterred contributions are of higher quality. We conclude that requiring accounts introduces an undertheorized tradeoff for public goods production in interactive communication systems.

description: Filtergrams obtained in Ca II H, Ca II K and H-alpha are often employed as diagnostics of the solar chromosphere. However, the vastly disparate appearance between the typical filtergrams in these different lines calls into question the nature of what is actually being observed. We investigate the lack of obvious structures of magnetic origin such as fibrils and mottles in on-disk Ca II H and K images by directly comparing a temporal sequence of classical Ca II K filtergrams with a co-spatial and co-temporal sequence of spectrally resolved Ca II 854.2 images obtained with the Interferometric Bidimensional Spectrometer (IBIS), considering the effect of both the spectral and spatial smearing. We find that the lack of fine magnetic structuring in Ca II K filtergrams, even with the narrowest available filters, is due to observational effects. Signatures of fibrils remain however in the temporal evolution of the filtergrams, in particular with the evidence of magnetic shadows around the network elements. The Ca II K filtergrams do not appear, however, to properly reflect the high-frequency behavior of the chromosphere. Using the same analysis, we find no significant chromospheric signature in the Hinode/SOT Ca II H quiet-Sun filtergrams. The picture provided by H-alpha and Ca II 854.2, which show significant portions of the chromosphere dominated by magnetic structuring, appears to reflect the true and essential nature of the solar chromosphere. Data which do not resolve, spatially or spectrally, this aspect may misrepresent the behavior the chromosphere.

description: Background: Risk management in maternity care aims to reduce incidents and harm to women and babies, contributing to quality care. However, there is growing concern that risk management policies may lead to unnecessary interventions during pregnancy and childbirth, resulting in both short- and long-term morbidity for women and their babies. Aim: To evaluate healthcare professionals’ perceptions of the effect of risk management on pregnancy and childbirth. Methods: A five-stage methodological framework was utilised in this review. A comprehensive integrative review was undertaken using a computer-assisted database approach including CINAHL, EMBASE, MEDLINE (Pubmed), PsycINFO and Scopus from 2016–2024. This review is reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-analysis for Scoping Reviews (PRISMA-ScR). Findings: The review identified five papers from four different countries. Two overarching themes were generated: The impact of the dominant medical model on risk management and decision-making in maternity care and the differences and similarities in healthcare professional’s perceptions of risk management. The increasing medicalisation of pregnancy and childbirth shifts healthcare professionals’ focus towards documentation and administrative tasks, driven by liability fears, rather than addressing clinical risks and providing woman-centred care. Conclusion: Complex factors influence risk management in maternity care. Risk management is affecting the way healthcare professionals think and operate. This review reveals that the medical model significantly shapes healthcare professionals’ perceptions of risk management, often undermining midwives’ autonomy and impacting decision-making in pregnancy and childbirth. Education and training are essential to restore mid-wives’ autonomous roles, ensuring that women receive the most appropriate, safest and highest quality of care

description: Compressing electron pulses is important in many applications of electron beam systems. In this study, we propose to use optical beat notes to compress electron pulses. The beat frequency is chosen to match the initial electron pulse duration, which enables the compression of electron pulses with a wide range of durations. This functionality extends the optical control of electron beams, which is important in compact electron beam systems such as dielectric laser accelerators. We also find that the dominant frequency of the electron charge density changes continuously along its drift trajectory, which may open up new opportunities in coherent interaction between free electrons and quantum or classical systems.

Um eine kontrollierbare und sichere Verbrennung dieses alternativen Brennstoffs zu gewährleisten, ist eine Analyse des Flug- und Verbrennungsverhaltens unerlässlich. In diesem Beitrag stellen wir Methoden zur Analyse von Bilddaten vor, die von einer Lichtfeldkamera während der Verbrennung von den aus Abfällen gewonnenen Brennstoffen in einem Drehrohr aufgenommen wurden. Das Kamerasystem liefert 3D-Informationen sowohl zu den Brennstoffpartikeln als auch zur inneren Form des Drehrohrofens. Die Analyse beinhaltet Verfahren zur Partikeldetektion unter Verwendung von 3D-Clustering-Algorithmen und Verfahren zur Partikelverfolgung unter Verwendung von Multi-Objekt-Tracking Algorithmen.

description: Robustness, the insensitivity of some of a biological system's functionalities to a set of distinct conditions, is intimately linked to fitness. Recent studies suggest that it may also play a vital role in enabling the evolution of species. Increasing robustness, so is proposed, can lead to the emergence of evolvability if evolution proceeds over a neutral network that extends far throughout the fitness landscape. Here, we show that the design principles used to achieve robustness dramatically influence whether robustness leads to evolvability. In simulation experiments, we find that purely redundant systems have remarkably low evolvability while degenerate, i.e. partially redundant, systems tend to be orders of magnitude more evolvable. Surprisingly, the magnitude of observed variation in evolvability can neither be explained by differences in the size nor the topology of the neutral networks. This suggests that degeneracy, a ubiquitous characteristic in biological systems, may be an important enabler of natural evolution. More generally, our study provides valuable new clues about the origin of innovations in complex adaptive systems.

description: The deception in the text can be of different forms in different domains, including fake news, rumor tweets, and spam emails. Irrespective of the domain, the main intent of the deceptive text is to deceit the reader. Although domain-specific deception detection exists, domain-independent deception detection can provide a holistic picture, which can be crucial to understand how deception occurs in the text. In this paper, we detect deception in a domain-independent setting using deep learning architectures. Our method outperforms the State-of-the-Art (SOTA) performance of most benchmark datasets with an overall accuracy of 93.42% and F1-Score of 93.22%. The domain-independent training allows us to capture subtler nuances of deceptive writing style. Furthermore, we analyze how much in-domain data may be helpful to accurately detect deception, especially for the cases where data may not be readily available to train. Our results and analysis indicate that there may be a universal pattern of deception lying in-between the text independent of the domain, which can create a novel area of research and open up new avenues in the field of deception detection.

description: J. Przytycki has established a connection between the Hochschild homology of an algebra $A$ and the chromatic graph homology of a polygon graph with coefficients in $A$. In general the chromatic graph homology is not defined in the case where the coefficient ring is a non-commutative algebra. In this paper we define a new homology theory for directed graphs which takes coefficients in an arbitrary $A-A$ bimodule, for $A$ possibly non-commutative, which on polygons agrees with Hochschild homology through a range of dimensions.

description: Cell-free massive multiple-input multiple-output (MIMO) employs a large number of distributed access points (APs) to serve a small number of user equipments (UEs) via the same time/frequency resource. Due to the strong macro diversity gain, cell-free massive MIMO can considerably improve the achievable sum-rate compared to conventional cellular massive MIMO. However, the performance of cell-free massive MIMO is upper limited by inter-user interference (IUI) when employing simple maximum ratio combining (MRC) at receivers. To harness IUI, the expanded compute-and-forward (ECF) framework is adopted. In particular, we propose power control algorithms for the parallel computation and successive computation in the ECF framework, respectively, to exploit the performance gain and then improve the system performance. Furthermore, we propose an AP selection scheme and the application of different decoding orders for the successive computation. Finally, numerical results demonstrate that ECF frameworks outperform the conventional CF and MRC frameworks in terms of achievable sum-rate.

description: 1/N_c baryon mass relations are compared with lattice simulations of baryon masses using different values of the light-quark masses, and hence different values of SU(3) flavor-symmetry breaking. The lattice data clearly display both the 1/N_c and SU(3) flavor-symmetry breaking hierarchies. The validity of 1/N_c baryon mass relations derived without assuming approximate SU(3) flavor-symmetry also can be tested by lattice data at very large values of the strange quark mass. The 1/N_c expansion constrains the form of discretization effects; these are suppressed by powers of 1/N_c by taking suitable combinations of masses. This 1/N_c scaling is explicitly demonstrated in the present work.

description: (abridged) Here we discuss the question whether the extreme circumstances in the centre of the Milky Way may be the reason for a significant variation of the IMF. By means of stellar evolution models using different codes we show that the observed luminosity in the central parsec is too high to be explained by a long-standing top-heavy IMF, considering the limited amount of mass inferred from stellar kinematics in this region. In contrast, continuous star formation over the Galaxy's lifetime following a canonical IMF results in a mass-to-light ratio and a total mass of stellar black holes (SBHs) consistent with the observations. Furthermore, these SBHs migrate towards the centre due to dynamical friction, turning the cusp of visible stars into a core as observed in the Galactic Centre. For the first time here we explain the luminosity and dynamical mass of the central cluster and both the presence and extent of the observed core, since the number of SBHs expected from a canonical IMF is just enough to make up for the missing luminous mass. We conclude that the Galactic Centre is consistent with the canonical IMF and do not suggest a systematic variation as a result of the region's properties such as high density, metallicity, strong tidal field etc.

description: In the multiverse, as in AdS, light-cones relate bulk points to boundary scales. This holographic UV-IR connection defines a preferred global time cut-off that regulates the divergences of eternal inflation. An entirely different cut-off, the causal patch, arises in the holographic description of black holes. Remarkably, I find evidence that these two regulators define the same probability measure in the multiverse. Initial conditions for the causal patch are controlled by the late-time attractor regime of the global description.

description: We summarize briefly the CKM picture of flavour and CP violation that governs the models with minimal flavour violation (MFV). We then describe how this framework can be efficiently tested through particle-antiparticle mixing and rare $K$ and B decays. In particular we provide a list of theoretically clean tests that the simplest version of the MFV framework, the constrained MFV hypothesis, has to face in the coming years. Finally we offer a brief look at the most popular SM extensions that go beyond the CKM framework like the general MSSM, Little Higgs model with T-parity and Randall-Sundrum models with bulk fermions.

description: Coalescing massive Black Hole binaries are the strongest and probably the most important gravitational wave sources in the LISA band. The spin and orbital precessions bring complexity in the waveform and make the likelihood surface richer in structure as compared to the non-spinning case. We introduce an extended multimodal genetic algorithm which utilizes the properties of the signal and the detector response function to analyze the data from the third round of mock LISA data challenge (MLDC 3.2). The performance of this method is comparable, if not better, to already existing algorithms. We have found all five sources present in MLDC 3.2 and recovered the coalescence time, chirp mass, mass ratio and sky location with reasonable accuracy. As for the orbital angular momentum and two spins of the Black Holes, we have found a large number of widely separated modes in the parameter space with similar maximum likelihood values.

description: Each single hydrogen vacancy created at the surface of graphane gives rise to a local unpaired spin. For domains of hydrogen vacancies the situation is, however complex and depends on the size and geometry of domains, as well as whether the domains are single- or double-sided. In single-sided domains, hydrogen atoms at the other side are relocated to pair the spins of adjacent carbon atoms by forming pi-bonds. Owing to the different characters of exchange coupling in different ranges and interplay between unpaired spin and the binding geometry of hydrogen, vacancy domains can attain sizable net magnetic moments. Our results based on the first-principles calculations suggest that the size and ordering of magnetic moments of hydrogen vacancy domains with thin walls can be used for future data storage and spintronics applications.

Application of geometric programming to PID controller tuning with state constraints
Creators: name: Carver, Leonard James
Publisher: name: University of British Columbia
Year: 2010

description: In the thesis, geometric programming is considered as a numerical optimization technique. The problem of minimizing the integral square error of a system characterized by a second order plant with proportional- integral-derivative (PID) controller is investigated. Constraints are imposed upon the state of the system In order to obtain feasible solutions and conditions that are amenable to the geometric programming technique. The application of geometric programming requires the use of approximation procedures to eliminate untenable conditions in the objective and constraint functions. The techniques utilized render solutions that are easily obtainable, usually amounting to solving a set of linear equations and requiring no differentiation of terms. In addition, there is rapid convergence to an optimum. The accuracy of the results is dependent upon the validity of the approximations.

description: CHRYSIS CAROLI DU BUYSSON, 1907
Linsenmaier (1994: 199, 1999: 250) synonymised C. caroli, described from Tunisia with C. jousseaumei because the two species share the dentate lower mesopleuron. However, the body sculpture and colour pattern of C. caroli are clearly different. In C. caroli the first tergum is densely micropunctate on interspaces among large punctures (Fig. 7F) (vs large, even punctures with polish interspaces in C. jousseaumei, Fig. 7E); the second tergum has even, mediumsized punctures and densely micropunctate interspaces (vs large punctures with polished interspaces in C. jousseaumei); the body color pattern in C. caroli is green with blue areas on mesosoma, and blue basal and lateral bands on metasomal segments, while it is entirely dark blue to purplish in C. jousseaumei. For these notable differences in diagnostic characters, we consider C. caroli du Buysson, 1907 as a valid species.

description: The interaction between a focused beam and a single classical oscillating dipole or a two-level system located at the focal spot is investigated. In particular, the ratio of the scattered to incident power is studied in terms of the oscillator's scattering cross section and the effective focal area. Debye diffraction integrals are applied to calculate it and results are reported for a directional dipolar wave. Multipole expansion of the incident beam is then considered and the equivalence between this and the Debye diffraction approach is discussed. Finally, the phase change of the electric field upon the interaction with a single oscillator is studied.

description: This thesis explores the profound impact of socioeconomic factors, inequality, parenting, and childhood experiences on the health outcomes, behaviors, and quality of life of children and adolescents in Australia. It highlights how higher socioeconomic status (SES) and reduced inequality enhance access to healthcare and education, leading to better health outcomes. Effective parenting fosters emotional stability and healthy behaviors, whereas adverse childhood experiences (ACEs) and socioeconomic disparities can cause long-term health and behavioral issues. Together, these factors shape the overall well-being and development of young individuals. The primary aim of this thesis is to investigate the roles of socioeconomic factors, inequality, parenting, and childhood experiences in shaping the health outcomes, behaviors, and quality of life of Australian children and adolescents. This PhD thesis, structured by publication, comprises six research articles and a systematic literature review (SLR). It utilizes data from the Longitudinal Study of Australian Children (LSAC) and employs multivariate regression models, generalized estimation equation models, concentration index, decomposition analysis, and relative inequalities index methods. The SLR adheres to PRISMA guidelines and involves databases such as EBSCO Host, PubMed, Web of Science, and ScienceDirect. The findings of these studies reveal that children from lower SES backgrounds are more prone to unhealthy behaviors such as such as smoking, poor diet, and physical inactivity, whereas those from higher SES backgrounds tend to adopt healthier habits like eating fruits and vegetables, maintaining a balanced diet, and being physically active. Parental characteristics and relationships, alongside household income, play a crucial role in shaping health disparities among Australian children and adolescents. Additionally, ACEs, such as physical punishment and parental conflict, increase the likelihood of problematic behaviors and negatively impact the health and health-related quality of life of children and adolescents. These findings provide valuable insights for health officials and policymakers, helping to identify at-risk groups and design targeted interventions to mitigate the effects of inequality on health and behaviors.

description: The problem of anomalously high levels of flicker noise observed in the normal state of the high-temperature superconductors is addressed. It is argued that the anomaly is the result of incorrect normalization of the power spectra according to the Hooge formula. A careful analysis of the available experimental data is given, which shows that the scaling of the spectral power with sample size is essentially different from the inverse proportionality. It is demonstrated that the measured spectra obey the law given by the recently proposed quantum theory of fundamental flicker noise.

description: We theoretically study a time-reversal-invariant three-dimensional superfluid model by stacking in $z$ direction identical bilayer models with intralayer spin-orbit coupling and contrary Zeeman energy splitting for different layer, which has been suggested recently to realize two-dimensional time-reversal-invariant topological superfluid. We find that this model shows two kinds of topologically nontrivial phases: gapless phases with nodal lines in pairs protected by chiral symmetry and a gapped phase, both of which support time-reversal-invariant Majorana Fermi arc (MFA) on the $yz$ and $xz$ side surface. These MFA abide by time-reversal and particle-hole symmetries and are topologically protected by the winding numbers in mirror subspaces and $Z_2$ numbers of two-dimensional DIII class topological superfluid, different from MFA in the time-reversal broken Weyl superfluid protected by nonzero Chern number. This important observation means that MFA in our model represents a new type of topological state not explored previously. The Zeeman field configuration in our model is relevant to antiferromagnetic topological insulator MnBi$_2$Te$_4$, thus our work stimulates the further studies on superconducting effects in the realistic antiferromagnetic topological insulator.

Vacuum deposited optical phase filters
Creators: name: Graf, Stephen
Publisher: name: University of British Columbia
Year: 2010

description: The advantages of an optical spatial phase filter constructed by thickness variations are put forward and a method of fabricating such a device using vacuum deposition techniques is detailed. The design and construction of a vacuum system to produce such a device is outlined. The system comprises a vacuum chamber with a source holder for zinc sulfide, an electronically controlled shutter, an aperture, and a substrate and holder mounted on an x-y motion table driven by stepper motors. The system is controlled by a minicomputer and measurements of thickness are made by an ellipsometer controlled by the minicomputer. Experiments conducted with the system determine the spatial resolution and closed loop control capabilities to be adequate. An analysis of the results of the tests concludes that with further refinements it seems feasible to fabricate spatial phase filters by using vacuum deposition techniques.
Signomial programs with equality constraints : numerical solution and applications
Creators: name: Yan, James
Publisher: name: University of British Columbia
Year: 2010

description: Many design problems from diverse engineering disciplines can be formulated as signomial programs with both equality and inequality constraints. However, existing computational methods of signomial programming are applicable to programs with inequality constraints only. In this thesis an algorithm is proposed and implemented to solve signomial programs with mixed inequality and equality constraints. The algorithm requires no manipulation of the constraints by the user and is compatible with the results of signomial programming. The proposed algorithm is a synthesis shaped by three concepts: the method of multipliers viewed as a primal-dual method, partial dualization, and the retention of the structure of a signomial program. The strategy of the algorithm is to replace the original problem with a sequence of subproblems each subject to the original signomial inequality constraints only. The subproblem's objective function is the original cost augmented with the equality constraints and specified by a parameter vector λ and a penalty constant K. The algorithm then alternates between solving the subproblem and updating λ and K. The convergence of the algorithm is, under suitable assumptions, guaranteed by the convergence of the method of multipliers and the method used to solve the subproblem. Because the subproblem has the form of a regular signomial program, it can in principle be solved by the techniques of signomial programming. A new numerical method implementing a variant of the Avriel-Williams algorithm for signomial programs is suggested for solving the subproblem. The method relies on monomial condensation, and the combined use of the reduced gradient method and a cutting plane scheme. Details of the method's implementation are considered, and some computational experience has been acquired. The proposed method also has the advantageous flexibility of being able to handle non-signomial differentiable objective functions. Four updating schemes for λ and K are formulated and evaluated in a series of numerical experiments. In terms of the rate of convergence, the most promising scheme tested is the use of the Hestenes-Powell rule for updating λ and the moderate monotonic increase of K after the completion of each subproblem. Convergence can also be considerably accelerated by properly scaling the equality constraints and performing only inexact minimization in the first few subproblems. The applicability of the algorithms developed in this thesis is illustrated with the solution of three design examples drawn from structural design and chemical process engineering.

description: Esta comunicação apresenta o art game WAYFINDER e articula uma compreensão sobre seus aspectos conceituais, poéticos, estéticos e tecnológicos, apoiada pelo conceito de ecologia das mídias. Desenvolvido pelo artista Matt Deslauriers, WAYFINDER é uma experiência efêmera que utiliza de uma mistura de inteligência artificial, aprendizado de máquina e de processos generativos para explorar infinitas possibilidades de percursos pela terra da poesia. Elementos são recolhidos ao longo do caminho, gerando palavras que formam versos de um Haicai, evocando de forma lúdica a efemeridade da natureza como tema central. Os estudos de ecologia das mídias abordam os efeitos que o surgimento das tecnologias produz nas sociedades humanas, como a interação com as novas mídias afetam suas percepções, sentimentos e valores. Pretendemos abordar WAYFINDER, por tanto, como um desdobramento midiático entre a poesia, as artes (audio)visuais e as novas tecnologias, e explorar suas possibilidades no campo da educação.

description: Two forms of ohmic heating of astrophysical secondaries have received particular attention: unipolar-generator heating with currents running between the primary and secondary; and magnetic induction heating due to the primary's time-varying field. Neither appears to cause significant dissipation in the contemporary solar system. But these discussions have overlooked heating derived from the spatial variation of the primary's field across the interior of the secondary. This leads to Lorentz force-driven currents around paths entirely internal to the secondary, with resulting ohmic heating. We examine three ways to drive such currents, by the cross product of: (1) the secondary's azimuthal orbital velocity with the non-axially symmetric field of the primary; (2) the radial velocity (due to non-zero eccentricity) of the secondary with the primary's field; or (3) the out-of-plane velocity (due to non-zero inclination) with the primary's field. The first of these operates even for a spin-locked secondary whose orbit has zero eccentricity, in strong contrast to tidal dissipation. We show that Jupiter's moon Io today could dissipate about 600 GW (more than likely current radiogenic heating) in the outer hundred meters of its metallic core by this mechanism. Had Io ever been at 3 jovian radii instead of its current 5.9, it could have been dissipating 15,000 GW. Ohmic dissipation provides a mechanism that could operate in any solar system to drive inward migration of secondaries that then necessarily comes to a halt upon reaching a sufficiently close distance to the primary.

description: We study the process of fully nonlinear dynamical scalarization starting from a charged black hole or a naked singularity in asymptotically flat spacetime in the Einstein-Maxwell-dilaton theory. Initially the dilaton field is negligible compared to the gravitational and the Maxwell field. Then the dilaton field experiences an immediate growth, later it oscillates with damping amplitude and finally settles down to a finite value. For a hairy black hole develops from an original Reissner-Nordström black hole, since the dilaton oscillation and decay are almost independent of the coupling parameter, unlike the Anti-de Sitter spacetime it is not easy to distinguish the resulting hairy black hole from the original asymptotically flat charged hole. For a hairy black hole evolves from an original naked singularity, the resulting hairy black hole has rich structures. In the scalarization process, the naked singularity is soon enveloped by one outer horizon, then another horizon is developed and in the end a stable hairy black hole forms and two horizons degenerate into one to protect the singularity. The hairy black hole mass saturates exponentially in the scalarization.

description: Ensuring proper punctuation and letter casing is a key pre-processing step towards applying complex natural language processing algorithms. This is especially significant for textual sources where punctuation and casing are missing, such as the raw output of automatic speech recognition systems. Additionally, short text messages and micro-blogging platforms offer unreliable and often wrong punctuation and casing. This survey offers an overview of both historical and state-of-the-art techniques for restoring punctuation and correcting word casing. Furthermore, current challenges and research directions are highlighted.
