description: In this work, we focus on separable convex optimization problems with box constraints and a set of triangular linear constraints. The solution is given in closed-form as a function of some Lagrange multipliers that can be computed through an iterative procedure in a finite number of steps. Graphical interpretations are given casting valuable insights into the proposed algorithm and allowing to retain some of the intuition spelled out by the water-filling policy. It turns out that it is not only general enough to compute the solution to different instances of the problem at hand but also remarkably simple in the way it operates. We also show how some power allocation problems in signal processing and communications can be solved with the proposed algorithm.

description: The quantum ground state of a massive mechanical system is a steppingstone for investigating macroscopic quantum states and building high fidelity sensors. With the recent achievement of ground-state cooling of a single motional mode, levitated nanoparticles have entered the quantum domain. To overcome detrimental cross-coupling and decoherence effects, quantum control needs to be expanded to more system dimensions, but the effect of a decoupled dark mode has thus far hindered cavity-based ground state cooling of multiple mechanical modes. Here, we demonstrate two-dimensional (2D) ground-state cooling of an optically levitated nanoparticle. Utilising coherent scattering into an optical cavity mode, we reduce the occupation numbers of two separate centre-of-mass modes to 0.83 and 0.81, respectively. By controlling the frequency separation and the cavity coupling strengths of the nanoparticle's mechanical modes, we show the transition from 1D to 2D ground-state cooling while avoiding the effect of dark modes. Our results lay the foundations for generating quantum-limited high orbital angular momentum states with applications in rotation sensing. The demonstrated 2D control, combined with already shown capabilities of ground-state cooling along the third motional axis, opens the door for full 3D ground-state cooling of a massive object.

description: Spin-transfer torques induced by temperature gradients in conducting ferromagnets are calculated microscopically for smooth magnetization textures. Temperature gradients are treated a la Luttinger by introducing a fictitious gravitational field that couples to the energy density. The thermal torque coefficients obtained by the Kubo formula contain divergences caused by equilibrium components that should be subtracted before applying the Einstein-Luttinger relation. Only by following this procedure a familiar Mott-like formula is obtained for the dissipative spin-transfer torque. The result indicates that a fictitious field coupled to the entropy rather than energy would solve the issue from the outset.

description: The massive presence of silent members in online communities, the so-called lurkers, has long attracted the attention of researchers in social science, cognitive psychology, and computer-human interaction. However, the study of lurking phenomena represents an unexplored opportunity of research in data mining, information retrieval and related fields. In this paper, we take a first step towards the formal specification and analysis of lurking in social networks. We address the new problem of lurker ranking and propose the first centrality methods specifically conceived for ranking lurkers in social networks. Our approach utilizes only the network topology without probing into text contents or user relationships related to media. Using Twitter, Flickr, FriendFeed and GooglePlus as cases in point, our methods' performance was evaluated against data-driven rankings as well as existing centrality methods, including the classic PageRank and alpha-centrality. Empirical evidence has shown the significance of our lurker ranking approach, and its uniqueness in effectively identifying and ranking lurkers in an online social network.

Certains enfants en difficultés n’arrivent pas à se représenter mentalement une notion ou un concept. Ce matériel peut les aider dans ce domaine-là. Certains élèves doivent passer par différents stades, dont la manipulation pour intégrer mentalement ces différentes notions.

Pour ce travail de recherche, nous avons choisi la thématique de l’espace, plus précisément de celle des solides. Ce mémoire montre l’utilité que peut avoir l’utilisation du matériel par les élèves. Il peut convaincre les enseignants d’utiliser le matériel à disposition mais également d’utiliser les objets courants et improvisés (le contenu d’une trousse par exemple). Le matériel ne sera peut être pas utile pour tous les élèves, il sera cependant indispensable pour d’autres.Nous pensons que la manipulation peut se faire à tout âge et pas seulement dans les petits degrés.

description: La singularidad que se observa en el comportamiento de distintos individuos ha sido objeto de interés desde los inicios de la psicología como disciplina científica. Los estudios en este ámbito resaltan la importancia de que, aunque era posible establecer principios generales sobre el comportamiento, también era posible analizar su singularidad e individualidad. Aunque con un pasado bastante amplio, en general, las estrategias de investigación para analizar tal dimensión de lo psicológico se enfocaron en el análisis de las diferencias individuales per se, lo que al final solo concluyó en señalar que cada individuo se comporta de manera diferente a otro. Las metodologías utilizadas para estudiarlo, el campo de la individualidad o la llamada personalidad constituyó un espacio dominado por el uso de pruebas o cuestionarios con reactivos verbales en los que las personas debían responder con base en aquello que consideraban pertinente para cada caso. Esos mismos resultados, se analizaron en términos estadísticos para ubicar al individuo en función de la distribución de la muestra. Es decir, la aparente singularidad sólo se daba como resultado de su comparación estadística con el resto de los individuos que conformaban la muestra. Una alternativa contemporánea a tales concepciones teóricas y metodológicas es la propuesta de los estilos conductuales de Emilio Ribes. Los estilos conductuales constituyen la manera idiosincrática, singular y consistente en que los individuos se comportan ante diversas situaciones. Se reconoce que los estilos conductuales pueden dividirse en cuatro categorías: estilos interactivos, estilos prolativos, estilos prelativos y estilos de agregación. El interés del presente trabajo consiste en realizar una propuesta metodológica para el estudio de los estilos de agregación, los que se refieren a la manera singular y consistente de interactuar en una situación en la que se encuentran presentes al menos otros dos individuos, es decir, una situación grupal.

description: We demonstrate that the Ising model on a general triangular graph with 3 distinct couplings $K_1,K_2,K_3$ corresponds to an affine transformed conformal field theory (CFT). Full conformal invariance of the $c= 1/2$ minimal CFT is restored by introducing a metric on the lattice through the map $\sinh(2K_i) = \ell^*_i/ \ell_i$ which relates critical couplings to the ratio of the dual hexagonal and triangular edge lengths. Applied to a 2d toroidal lattice, this provides an exact lattice formulation in the continuum limit to the Ising CFT as a function of the modular parameter. This example can be viewed as a quantum generalization of the finite element method (FEM) applied to the strong coupling CFT at a Wilson-Fisher IR fixed point and suggests a new approach to conformal field theory on curved manifolds based on a synthesis of simplicial geometry and projective geometry on the tangent planes.

Intimate Partner Violence

description: Intimate partner violence (IPV) involves aggressive or abusive behaviour that harms or intimidates a current or former romantic partner. Although sexual and gender diverse (2S/LGBTQIA+) people may disproportionately experience IPV, their experiences are not well documented in the Canadian context. This multi-methods qualitative study documents 2S/LGBTQIA+ survivors’ experiences with IPV and access to related services throughout the COVID-19 pandemic via in-depth interviews with survivors and service providers. Survivors experienced multiple, concurrent forms of abuse that contributed to poor mental health outcomes, both of which were intensified by the COVID-19 pandemic. Survivors had difficulty recognizing themselves as victims and were unaware of services. Services are insufficiently funded and unable to meet the needs of their communities. Gender-based violence organizations want to serve transgender women and transfeminine people but second-wave feminist frameworks in policy and funding mechanisms are a barrier to expanding services. Service providers need predictable, annualized funding, must improve outreach, and shift to an intersectional feminist framework that includes 2S/LGBTQIA+ people. Comprehensive sexual health education and regular IPV screenings by mental health professionals are crucial for IPV prevention.

description: A Sierpiński packing in the $2$-sphere is a countable collection of disjoint, non-separating continua with diameters shrinking to zero. We show that any Sierpiński packing by continua whose diameters are square-summable can be uniformized by a disk packing with a packing-conformal map, a notion that generalizes conformality in open sets. Being special cases of Sierpiński packings, Sierpiński carpets and some domains and can be uniformized by disk packings as well. As a corollary of the main result, the conformal loop ensemble (CLE) carpets can be uniformized conformally by disk packings, answering a question of Rohde-Werness.

description: The laser is an out-of-equilibrium nonlinear wave system where the interplay of the cavity geometry and nonlinear wave interactions, mediated by the gain medium, determines the self-organized oscillation frequencies and the associated spatial field patterns. In the steady state, a constant energy flux flows through the laser from the pump to the far field, with the ratio of the total output power to the input power determining the power-efficiency. While nonlinear wave interactions have been modeled and well understood since the early days of laser theory, their impact on the power-efficiency of a laser system is poorly understood. Here, we show that spatial hole burning interactions generally decrease the power efficiency. We then demonstrate how spatial hole burning interactions can be controlled by a spatially tailored pump profile, thereby boosting the power-efficiency, in some cases by orders of magnitude.

State of the Art in the Characterization of Nano-and Atomic-Scale Catalysts
Creators: Laishram, Devika
Publisher: name: University of Alberta Library
Year: 2022

Nanometer and subnanometer particles and films are becoming an essential and integral part of new technologies and inventions in different areas. Some of the most common areas include the microelectronic industry, magnetic recordings, photovoltaic applications, and optical coatings. Because of the ultrasmall size at atomic levels, the effect of quantum size becomes prominent, and the sensitivity of size is defined even by a difference of a single atom. Additionally, the effect is of utmost importance as the single-atom catalysts are far more advantageous than conventional catalysts as they tend to anchor easily because of their low coordination. Also, the presence of a single-atom catalyst in reactions creates efficient charge transfer as it forms a strong interaction with the support. Furthermore, catalysts in the subnanometer regime exhibit different electronic states and adsorption capabilities compared to traditional catalysts. Therefore, to fully appreciate the subnanometer catalysis reactions, it is essential to study the means of characterizing the prepared subnano catalysts, in order to characterize the materials in their as-synthesized form, to obtain a precise and accurate analysis; these are some of the fundamental requirements for achieving an optimum performance. The physical properties of many interesting materials for advanced technological usage are highly governed by the distribution and placement of atoms. Superior techniques such as high-resolution transmission electron microscopy and high-angle annular dark-field scanning transmission electron microscopy and infrared and X-ray absorption spectroscopic techniques provide electronic and geometric configurations and also reveal the transformation of the subnano catalysts on the support material. Modeling methods such as density functional theory can successfully predict the electronic structure and geometric configuration of the catalyst, which in turn influence the selectivity and activity of the catalyst. Thus, understanding the characterization techniques gives the ability to understand, identify, and measure the local environment of individual atoms and the interaction with the surface support, which will give fundamental knowledge and insights in the realms of nanoscience and technology, materials science, chemistry, and physics. Therefore, detection and enhanced measurement of individual atoms is inherently challenging and is a prerequisite to the development of new technology and better performing materials. In this chapter, we have discussed various important methods of characterization for characterizing subnanometer and atomic catalysts.

description: The Newman-Janis algorithm is supplemented with a null rotation and applied to the tensors of the Reissner-Nordström spacetime to generate the metric, Maxwell, Ricci and Weyl tensors for the Kerr-Newman spacetime. This procedure also provides a mechanism whereby the Carter Killing tensor arises from the geodesic angular momentum tensor of the underlying Reissner-Nordström metric. The conformal Killing tensor in the Kerr-Newman spacetime is generated in a similar fashion. The extended algorithm is also applied to the Killing vectors of the Reissner-Nordström spacetime with interesting consequences. The Schwarzschild to Kerr transformation is a special case.

description: Radar and communications (R&C) as key utilities of electromagnetic (EM) waves have fundamentally shaped human society and triggered the modern information age. Although R&C have been historically progressing separately, in recent decades they have been converging towards integration, forming integrated sensing and communication (ISAC) systems, giving rise to new, highly desirable capabilities in next-generation wireless networks and future radars. To better understand the essence of ISAC, this paper provides a systematic overview on the historical development of R&C from a signal processing (SP) perspective. We first interpret the duality between R&C as signals and systems, followed by an introduction of their fundamental principles. We then elaborate on the two main trends in their technological evolution, namely, the increase of frequencies and bandwidths, and the expansion of antenna arrays. We then show how the intertwined narratives of R&C evolved into ISAC, and discuss the resultant SP framework. Finally, we overview future research directions in this field.

description: We present a perturbative QCD analysis concerning the production of high-pT dijets in p+Pb collisions at the LHC. The next-to-leading order corrections, scale variations and free-proton PDF uncertainties are found to have only a relatively small influence on the normalized dijet rapidity distributions. Interestingly, however, these novel observables prove to retain substantial sensitivity to the nuclear effects in the PDFs. Especially, they serve as a more robust probe of the nuclear gluon densities at $x>0.01$, than e.g. the inclusive hadron production. We confront our calculations with the recent data by the CMS collaboration. These preliminary data lend striking support to the gluon antishadowing similar to that in the EPS09 nuclear PDFs.

description: We present an image processing algorithm developed for quantitative analysis of directional solidification of metal alloys in thin cells using X-ray imaging. Our methodology allows to identify the fluid volume, fluid channels and cavities, and to separate them from the solidified structures. It also allows morphological analysis within the solid fraction, including automatic decomposition into dominant grains by orientation and connectivity. In addition, the interplay between solidification and convection can be studied by characterizing convection plumes in the fluid, and solute concentrations above the developing solidification front. The image filters used enable the developed code (open-source) to work reliably even for single images with low signal-to-noise ratio, low contrast-to-noise ratio, and low image resolution. This is demonstrated by applying the code to several dynamic in situ X-ray imaging experiments with a solidifying gallium-indium alloy in a thin cell. Grain (and global) dendrite orientation statistics, convective plume parameterization, etc. can be obtained from the code output. The limitations of the presented approach are also explained.

We derive explicitly the universal locking dynamics for entrainment of patterns breaking internal phase symmetry, and calculate the locking domains and the entrainment structure for the example of complex-Ginzburg-Landau solitons.

description: We introduce a concept of semi-shunts representing needle shaped metallic protrusions shorter than the distance between a device electrodes. Due to the lightening rod type of field enhancement, they induce strong electron emission. We consider the corresponding signature effects in photovoltaic applications; they are: low open circuit voltages and exponentially strong random device leakiness. Comparing the proposed theory with our data for CdTe based solar cells, we conclude that stress can stimulate semi-shunts' growth making them shunting failure precursors. In the meantime, controllable semi-shunts can play a positive role mitigating the back field effects in photovoltaics.

description: A value-added tax (VAT) has been mentioned as an alternative to increasing Federal taxes. Since the Common Market has implemented such a tax, current literature draws heavily upon the EC experience. However, differences between U.S. and Common Market conditions have led to confusion over the nature of a value-added tax and its possible use in this country. Exactly how the VAT would affect various sectors of the U.S. economy would depend in part upon the method used to calculate the tax and the Government's method of imposing the tax. Adoption of a new tax such as a VAT might give the United States the opportunity to undertake desired reforms in its tax structure without either increasing the impact of present taxes on taxpayers or reducing total Federal tax revenues. Should a U.S. value-added tax be adopted, farmers should, to the greatest possible extent, be full participants in the tax plan for best results. For instance, exemption for farmers would penalize them since they would have no means of claiming credit for taxes paid on inputs. At the same time, recognition of special characteristics of agriculture is necessary, particularly where small farmers are concerned.

description: The topological structure of lattice gluodynamics is studied at intermediate resolution scale in the deconfining phase with the help of a cluster analysis. UV filtered topological charge densities are determined from a fixed number of low-lying eigenmodes of the overlap Dirac operator with three types of temporal boundary conditions applied to the valence quark fields. This method usually allows to find all three distinguished (anti)dyon constituents in the gauge field of Kraan-van Baal-Lee-Lu (anti)caloron solutions. The clustering of the three topological charge densities in Monte Carlo generated configurations is then used to mark the positions of anticipated (anti)dyons of the corresponding type. In order to support this interpretation, inside these clusters, we search also for time-like Abelian monopole currents (defined in the maximally Abelian gauge) as well as for local holonomies with at least two approximately degenerated eigenvalues. Our results support the view that light dyon-antidyon pairs - in contrast to the heavy (anti)caloron dyon constituents - contribute dominantly to thermal Yang-Mills fields in the deconfinement phase. This paper is dedicated to the memory of Pierre van Baal and Dmitri Igorevich Diakonov who have influenced our work very much.

description: We study the relative fractions of quenched and star-forming satellite galaxies in the Satellites Around Galactic Analogs (SAGA) survey and Exploration of Local VolumE Satellites (ELVES) program, two nearby and complementary samples of Milky Way-like galaxies that take different approaches to identify faint satellite galaxy populations. We cross-check and validate sample cuts and selection criteria, as well as explore the effects of different star-formation definitions when determining the quenched satellite fraction of Milky Way analogs. We find the mean ELVES quenched fraction ($\langle QF\rangle$), derived using a specific star formation rate (sSFR) threshold, decreases from $\sim$50% to $\sim$27% after applying a cut in absolute magnitude to match that of the SAGA survey ($\langle QF\rangle_{SAGA}\sim$9%). We show these results are consistent for alternative star-formation definitions. Furthermore, these quenched fractions remain virtually unchanged after applying an additional cut in surface brightness. Using a consistently-derived sSFR and absolute magnitude limit for both samples, we show that the quenched fraction and the cumulative number of satellites in the ELVES and SAGA samples broadly agree. We briefly explore radial trends in the ELVES and SAGA samples, finding general agreement in the number of star-forming satellites per host as a function of radius. Despite the broad agreement between the ELVES and SAGA samples, some tension remains with these quenched fractions in comparison to the Local Group and simulations of Milky Way analogs.

description: Ce mémoire contient premièrement un bref aperçu du contexte des écoles de Kinshasa, en République démocratique du Congo. Il a pour but de proposer un outil pédagogique gratuit et utilisable pour des enseignant.e.s qui n’ont que peu de moyens financiers à disposition. Le défi consiste à proposer de véritables séquences d’enseignement/apprentissage de la lecture permettant aux enseignantes de mettre en œuvre dans leur classe des activités visant l’apprentissage des correspondances phonèmes - graphèmes et l’affinement de la compréhension en lecture. De plus, une adaptation culturelle, tant dans le contenu que dans la façon d’enseigner, a été prise en compte. Enfin, les pistes proposées se trouvent dans la zone proximale de développement des enseignant.e.s, grâce aux réponses à des questionnaires envoyés sur place . Ensuite, se trouve un cadre théorique qui met en synergie divers savoirs sur l’apprentissage de la lecture. Ce cadre est construit pour mettre à jour les connaissances théoriques des enseignant.e.s, quelle que soit la formation qu’il.elle a suivi . Puis, ce dossier présente deux séquences d’enseignement/apprentissage de la lecture adaptées au contexte d’une école kinoise. La première travaille la compréhension d’un texte à travers l’étude des personnagesde l’album de littérature jeunesse Arc-en-ciel le plus beau poisson des océans, de Marcus Pfister. La deuxième séquence s’intéresse à la maîtrise du code en passant par l’apprentissage des liens entre les graphèmes et les phonèmes qui composent la langue française. Enfin, se trouve une liste de proposition de livres que les enseignant.e.s peuvent se procurer s’ils.elles désirent continuer d’enseigner la lecture en s’appuyant sur les séquences types.

Fluid flow enhances the effectiveness of toxin export by aquatic microorganisms: a first-passage perspective on microvilli and the concentration boundary layer

description: A central challenge for organisms during development is determining a means to efficiently export toxic molecules from inside the developing embryo. For aquatic microorganisms, the strategies employed should be robust with respect to the variable ocean environment and limit the chances that exported toxins are reabsorbed. As a result, the problem of toxin export is closely related to the physics of mass transport in a fluid. In this paper we consider a model first-passage problem for the uptake of exported toxins by a spherical embryo. By considering how macroscale fluid turbulence manifests itself on the microscale of the embryo, we determine that fluid flow enhances the effectiveness of toxin export as compared to the case of diffusion-limited transport. In the regime of large Péclet number, a perturbative solution of the advection-diffusion equation reveals that a concentration boundary layer forms at the surface of the embryo. The model results suggest a functional role for cell surface roughness in the export process, with the thickness of the concentration boundary layer setting the length scale for cell membrane protrusions known as microvilli. We highlight connections between the model results and experiments on the development of sea urchin embryos.

description: Deep learning (DL) methods have been widely applied to anomaly-based network intrusion detection system (NIDS) to detect malicious traffic. To expand the usage scenarios of DL-based methods, federated learning (FL) allows multiple users to train a global model on the basis of respecting individual data privacy. However, it has not yet been systematically evaluated how robust FL-based NIDSs are against existing privacy attacks under existing defenses. To address this issue, we propose two privacy evaluation metrics designed for FL-based NIDSs, including (1) privacy score that evaluates the similarity between the original and recovered traffic features using reconstruction attacks, and (2) evasion rate against NIDSs using adversarial attack with the recovered traffic. We conduct experiments to illustrate that existing defenses provide little protection and the corresponding adversarial traffic can even evade the SOTA NIDS Kitsune. To defend against such attacks and build a more robust FL-based NIDS, we further propose FedDef, a novel optimization-based input perturbation defense strategy with theoretical guarantee. It achieves both high utility by minimizing the gradient distance and strong privacy protection by maximizing the input distance. We experimentally evaluate four existing defenses on four datasets and show that our defense outperforms all the baselines in terms of privacy protection with up to 7 times higher privacy score, while maintaining model accuracy loss within 3% under optimal parameter combination.
