description: The recent interest in modified theories of gravity, involving some type of non-minimal coupling to the Ricci scalar, and the calculation of cosmological observables in the Einstein or the Jordan frame, motivate the formulation of these theories in terms of quantities that are invariant under frame transformations. Furthermore, in view of the description of gravity and its geometry motivated by string theory, such a formulation could be extended to include theories of extra spatial dimensions. In the present article, we generalize the construction of frame-invariant quantities, concerning a general, $D$-dimensional scalar-tensor theory. Then, we limit our scope to the 5D braneworld scenario, where we study thick brane solutions that are localized on the 3-brane and extend the invariant formulation to the case of multiple scalar fields (non-)minimally coupled to gravity.

description: We introduce Higgs democracy in the Yukawa sector by constructing a model with a private Higgs and a dark scalar for each fermion thus addressing the large hierarchy among fermion masses. The model has interesting implications for the LHC, while the Standard Model phenomenology is recovered at low energies. We discuss some phenomenological implications such as FCNC, new Higgses at the TeV scale and dark matter candidates.

Identifying a $Z'$ behind $b \to s \ell \ell$ anomalies at the LHC

description: Recent $b\to s\ell\ell$ anomalies may imply the existence of a new $Z'$ boson with left-handed $Z'bs$ and $Z'μμ$ couplings. Such a $Z'$ may be directly observed at LHC via $b \bar s \to Z' \to μ^+μ^-$, and its relevance to $b\to s\ell\ell$ may be studied by searching for the process $gs \to Z'b \to μ^+μ^- b$. In this paper, we analyze the capability of the 14 TeV LHC to observe the $Z'$ in the $μ^+ μ^-$ and $μ^+μ^- b$ modes based on an effective model with major phenomenological constraints imposed. We find that both modes can be discovered with 3000 fb$^{-1}$ data if the $Z'bs$ coupling saturates the latest $B_s-\bar B_s$ mixing limit from UTfit at around $2σ$. Besides, a tiny right-handed $Z'bs$ coupling, if it exists, opens up the possibility of a relatively large left-handed counterpart, due to cancellation in the $B_s-\bar B_s$ mixing amplitude. In this case, we show that even a data sample of $\mathcal{O}(100)$ fb$^{-1}$ would enable discovery of both modes. We further study the impact of a $Z'bb$ coupling as large as the $Z'bs$ coupling. This scenario enables discovery of the $Z'$ in both modes with milder effects on the $B_s-\bar B_s$ mixing, but obscures the relevance of the $Z'$ to $b \to s\ell\ell$. Discrimination between the $Z'bs$ and $Z'bb$ couplings may come from the production cross section for the $Z'b\bar{b}$ final state. However, we do not find the prospect for this to be promising.

description: We give conditions under which near-critical stochastic processes on the half-line have infinitely many or finitely many cutpoints, generalizing existing results on nearest-neighbour random walks to adapted processes with bounded increments satisfying appropriate conditional increment moments conditions. We apply one of these results to deduce that a class of transient zero-drift Markov chains in $\mathbb{R}^d$, $d \geq 2$, possess infinitely many separating annuli, generalizing previous results on spatially homogeneous random walks.

Probabilistic Approaches for Pose Estimation

Publisher: name: Carnegie Mellon University

Subjects: subject: 80101 Adaptive Agents and Intelligent Robotics
subject: FOS: Computer and information sciences

description: Virtually all robotics and computer vision applications require some form of pose estimation; such as registration, structure from motion, sensor calibration, etc. This problem is challenging because it is highly nonlinear and nonconvex. A fundamental contribution of this thesis is the development of fast and accurate pose estimation by formulating in a parameter space where the problem is truly linear and thus globally optimal solutions can be guaranteed. It should be stressed that the approaches developed in this thesis are indeed inherently linear, as opposed to using linearization or other approximations, which are known to be computationally expensive and highly sensitive to initial estimation error. This thesis will demonstrate that the choice of probability distribution significantly impacts performance of the estimator. The distribution must respect the underlying structure of the parameter space to ensure any optimization, based on such a distribution, produces a globally optimal estimate, despite the inherent nonconvexity of the parameter space. Furthermore, in applications such as registration and 3D reconstruction, the correspondence between the measurements and the geometric model is typically unknown. In this thesis we develop probabilistic methods to deal with cases of unknown correspondence. While the resultant formulation does not guarantee global optimality, it increases the basin of convergence. Another contribution of this thesis is the development of a generalized framework for probabilistic point registration. By setting functional parameters such as sensor noise and prior uncertainties appropriately, our framework captures many prior registration methods. Additionally our framework is also capable of predicting scope for improvement in the existing algorithms, which are then verified experimentally. To tie the ideas together, we present results in the context of surgical robotics - in particular we demonstrate a surgical system that is capable of performing real-time tumor localization, hand-eye calibration, registration of preoperative models to the anatomy, and augmented reality.
Superconductivity in FeSe: the role of nematic order

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: Bulk FeSe is a special iron-based material in which superconductivity emerges inside a well-developed nematic phase. We present a microscopic model for this nematic superconducting state, which takes into account the mixing between $s-$wave and $d-$wave pairing channels and the changes in the orbital spectral weight promoted by the sign-changing nematic order parameter. We show that nematicity gives rise to a $\cos2θ$ variation of the pairing gap on the hole pocket that agrees with ARPES and STM data for experimentally-extracted Fermi surface parameters. We further argue that, in BCS theory, $d_{xz}$ and $d_{yz}$ orbitals give nearly equal contributions to the pairing glue, i.e. nematic order alone accounts for the gap anisotropy, but has little effect on $T_{c}$. This result questions the validity of the concept of orbital-selective pairing. Self-energy corrections, however, make $d_{xz}$ orbital more incoherent and reduce its contribution to pairing.

Long semiclassical trajectories are strongly affected by static disorder and differ sharply from those of clean systems. They give rise to a large linear paramagnetic susceptibility which is disorder independent and in agreement with recent experiments. The crossover field to a nonlinear susceptibility is discussed.

description: We investigate the asymptotic safety scenario for a scalar-gravity system. This system contains two avatars of the dynamical Newton coupling, a gravitational self-coupling and a scalar-graviton coupling. We uncover an effective universality for the dynamical Newton coupling on the quantum level: its momentum-dependent avatars are in remarkable quantitative agreement in the scaling regime of the UV fixed point. For the background Newton coupling, this effective universality is not present, but qualitative agreement remains.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: The Jacobian for infinitesimal BRST transformations of path integrals for pure Yang-Mills theory, viewed as a matrix $\unity +ΔJ$ in the space of Yang-Mills fields and (anti)ghosts, contains off-diagonal terms. Naively, the trace of $ΔJ$ vanishes, being proportional to the trace of the structure constants. However, the consistent regulator $\cR$, constructed from a general method, also contains off-diagonal terms. An explicit computation demonstrates that the regularized Jacobian $Tr\ ΔJ\exp -\cR /M^2$ for $M^2\rightarrow \infty $ is the variation of a local counterterm, which we give. This is a direct proof at the level of path integrals that there is no BRST anomaly.

description: function of the CEP, we observe a transition from a modulated to a continuous SHHG spectrum, indicating the transition from double to high-contrast isolated attosecond pulse emission. Single shot-acquisitions of XUV spectral continua support isolated attosecond pulses with isolation degrees between 10 and 50 for the majority of the driving pulse CEPs, which represents a significant improvement in terms of isolation degree as well as repetition rate over previous results obtained with 2-cycle drivers at 10-Hz. 2D Particle-in-cell simulations corroborate this interpretation and predict percent-level efficiencies for the generation of an isolated attosecond pulse even without any spectral filtering.

description: The question of a modification of the running gauge coupling of (non-) abelian gauge theories by an incorporation of the quantum gravity contribution has recently attracted considerable interest. In this letter we perform an involved diagrammatical calculation in the full Einstein-Yang-Mills system both in cut-off and dimensional regularization at one loop order. It is found that all gravitational quadratic divergencies cancel in cut-off regularization and are trivially absent in dimensional regularization so that there is no alteration to asymptotic freedom at high energies. The logarithmic divergencies give rise to an extended effective Einstein-Yang-Mills Lagrangian with a counterterm of dimension six. In the pure Yang-Mills sector this counterterm can be removed by a nonlinear field redefinition of the gauge potential, reproducing a classical result of Deser, Tsao and van Nieuwenhuizen obtained in the background field method with dimensional regularization.

description: Mining projects affect the health of surrounding communities by inducing environmental, economic, social and cultural changes in different population groups. Health impact assessment (HIA) offers an opportunity to manage these impacts. This paper aims to explore gender differences of impacts on the wider determinants of health as described by communities impacted by industrial gold mining and consider the implications for impact assessment. We conducted 24 gender-separated, participatory focus group discussions at three study sites in northwestern Tanzania. Participants reported on a broad range of impacts on the wider determinants of health. Based on a thematic analysis, we identified gendered health impacts on men and women; in addition, children and adolescent boys and girls emerged as differently affected subpopulation groups. Located in the theory of the ‘triple role of women’, we suggest that different gender needs should be addressed more explicitly by HIA. Increased use of mitigation measures that recognise and address impacts on women’s engendered roles, and their health, through addressing women’s strategic gender needs, would strengthen HIA as a tool towards sustainable development.

description: We present a multi-wavelength spectral and temporal investigation of OJ 287 emission during its strong optical-to-X-ray activity between July 2016 - July 2017. The daily $γ$-ray fluxes from \emph{Fermi}-LAT are consistent with no variability. The strong optical-to-X-ray variability is accompanied by a change in power-law spectral index of the X-ray spectrum from $< 2$ to $>2$, with variations often associated with changes in optical polarization properties. Cross-correlations between optical-to-X-ray emission during four continuous segments show simultaneous optical-ultraviolet (UV) variations while the X-ray and UV/optical are simultaneous only during the middle two segments. In the first segment, the results suggest X-rays lag the optical/UV, while in the last segment X-rays lead by $\sim$ 5-6 days. The last segment also shows a systematic trend with variations appearing first at higher energies followed by lower energy ones. The LAT spectrum before the VHE activity is similar to preceding quiescent state spectrum while it hardens during VHE activity period and is consistent with the extrapolated VHE spectrum during the latter. Overall, the broadband spectral energy distributions (SEDs) during high activity periods are a combination of a typical OJ 287 SED and an HBL SED, and can be explained in a two-zone leptonic model, with the second zone located at parsec scales, beyond the broad line region, being responsible for the HBL-like spectrum. The change of polarization properties from systematic to chaotic and back to systematic, before, during and after the VHE activity, suggest dynamic roles for magnetic fields and turbulence.

description: Repositories have historically focused on a single use case, primarily the capture of traditional (text-based) open access publications, requiring separate solutions for different use cases (e.g. research data). This made capturing the wide variety of research outputs challenging at the University of Westminster, which engages in practice-based arts research (encompassing a range of disciplines, from fine and performing arts, to architecture and design and whose outputs tend to be in a non-text format) alongside traditional research. Building on a history of collaboration, Haplo and the University and its research community have built a single, open source repository meeting multiple use cases including text-based and non-text based outputs, portfolios and research data. Made possible through the flexible technical architecture of the Haplo platform, whose underlying technology is based on semantic web principles and meets COAR's vision for next-generation repositories. Improvements to the repository now enable better capture and display of research outputs across disciplines. Highlights include the development of dynamic portfolios, improved support for non-text based outputs and ongoing engagement with practice-based arts researchers to understand their needs, build workflows, review metadata and build, test and implement a transformed repository.

description: Scene classification is a fundamental problem to understand the high-resolution remote sensing imagery. Recently, convolutional neural network (ConvNet) has achieved remarkable performance in different tasks, and significant efforts have been made to develop various representations for satellite image scene classification. In this paper, we present a novel representation based on a ConvNet with context aggregation. The proposed two-pathway ResNet (ResNet-TP) architecture adopts the ResNet as backbone, and the two pathways allow the network to model both local details and regional context. The ResNet-TP based representation is generated by global average pooling on the last convolutional layers from both pathways. Experiments on two scene classification datasets, UCM Land Use and NWPU-RESISC45, show that the proposed mechanism achieves promising improvements over state-of-the-art methods.

description: Users share a large amount of information with modern platforms such as web platforms and social platforms for various services. However, they face the risk of information leakage because modern platforms still lack proper security policies. Existing security policies, such as permission systems and isolation, can help regulate information sharing. However, these policies have problems, such as coarse granularity, bad usability, and incompleteness, especially when new features are introduced. I investigate the security impacts of new features in web and mobile platforms and find design problems that lead to user information leakage. Based on these analyses, I propose design principles for permission systems that mediate how information should be shared in modern and emerging platforms, such as web and social platforms, to provide functionality with privacy preserved. I aim to design permission systems that only allow least-privilege information access. Specifically, I utilize program analysis and natural language processing to understand how applications use sensitive data and correlate these data with their functionality. With this understanding, I design schemes that ask for user consent about unexpected information access and automatically reduce overprivileged access. I provide guidelines for platform designers to build their permission systems according to respective adversary models and resources. In particular, I implement the new permission system for social platforms and Internet of Things (IoT) platforms that enable least-privilege information sharing. For the social platforms, I incorporate the primitives of Opaque handle, Opaque display, and User-driven access control (OOU) to design a least-privilege, user-friendly, developer-friendly, and feature-rich permission system. According to my study on Facebook, OOU can be applied to remove or replace 81.2% of sensitive permission instances without affecting functionality. For IoT platforms, I present a new authorization framework, SmartAuth, that supports user-centric, semantic-based authorization. SmartAuth automatically collects security-relevant information from an IoT application’s description, code, and annotations, and generates an authorization user interface to bridge the gap between the functionalities explained to the user and the operations the application actually performs.

description: We consider semi-infinite two-dimensional layered Ising models in the extreme anisotropic limit with an aperiodic modulation of the couplings. Using substitution rules to generate the aperiodic sequences, we derive functional equations for the surface magnetization. These equations are solved by iteration and the surface magnetic exponent can be determined exactly. The method is applied to three specific aperiodic sequences, which represent different types of perturbation, according to a relevance-irrelevance criterion. On the Thue-Morse lattice, for which the modulation is an irrelevant perturbation, the surface magnetization vanishes with a square root singularity, like in the homogeneous lattice. For the period-doubling sequence, the perturbation is marginal and the surface magnetic exponent varies continuously with the modulation amplitude. Finally, the Rudin-Shapiro sequence, which corresponds to the relevant case, displays an anomalous surface critical behavior which is analyzed via scaling considerations: Depending on the value of the modulation, the surface magnetization either vanishes with an essential singularity or remains finite at the bulk critical point, i.e., the surface phase transition is of first order.

description: We present the metal - insulator transition study of a quantum site percolation model on simple cubic lattice. Transfer matrix method is used to calculate transport properties - Landauer conductance - for the binary distribution of energies. We calculate the mobility edge in disorder (ratio of insulating sites) - energy plane in detail and we find the extremal critical disorder somewhat closer to the classical percolation threshold, than formerly reported. We calculate the critical exponent $ν$ along the mobility edge and find it constant and equal to the one of 3D Anderson model, confirming common universality class. Possible exception is the center of the conduction band, where either the single parameter scaling is not valid anymore, or finite size effects are immense. One of the reasons for such statement is the difference between results from arithmetic and geometric averaging of conductance at special energies. Only the geometric mean yields zero critical disorder in band center, which was theoretically predicted.

description: Decolonizing Me is a personal act of liberation and a professional and political imperative. I must write this book because I know what it feels like to be brilliant and afraid simultaneously. I know what it means to translate one’s existence to fit into systems never built for us. Moreover, I see the cost of staying silent. This book is my resistance to that silence. On a personal level, decolonizing addresses the fear of speaking out and the resistance towards continuing to be in fear. This is an ongoing battle. On a professional level, I have witnessed the long-term impact of colonization on how people seek therapy, on how therapists are trained, and on how communities are either heard or dismissed in systems of care. I have worked with clients who were not only processing trauma, but also trying to survive under the weight of being misunderstood by institutions, by therapists, and by the very cultures they hoped would help them heal. Unless questioned and reimagined, I have seen how psychological frameworks often replicate the same hierarchies they claim to dismantle. Although dividing the world into "West" and "East" is, on the surface, a broad and stereotypical framework, it nonetheless reflects the persistent struggles and hierarchies shaped by centuries of history. The traditional binary portraying the West as the land of developed democracies and the East as a region of underdeveloped or struggling nations oversimplifies a much more complex global reality. However, even when inaccurate, stereotypes often reveal more profound truths about power, dominance, and historical narrative. In this book, when I refer to "Western superpowers," I am not merely discussing geography or simplistic binaries. Instead, I am pointing to a mindset, a structure of global dominance, that has been embodied by powerful actors across both Western and non-Western nations. These forces, whether from Europe, North America, Russia, or elsewhere, have historically regarded Iran not as a sovereign nation rich in history, culture, and resilience, but as a "bait," an opportunity, a strategic market to control, extract from, and manipulate. This is why I must write Decolonizing Me: to create a space where personal stories and professional insight are braided together. To examine what it means to reclaim one’s voice in the face of long-standing systems of oppression. To offer a framework for understanding how history lives in the body and how healing can only begin when we are honest about the forces that shape our silence.

description: In proton-nucleus and nucleus-nucleus collision experiments, one determines the centrality of a collision according to the multiplicity or energy deposited in a detector. This serves as a proxy for the true collision centrality, as defined by the impact parameter. We show that the probability distribution of impact parameter in a given bin of experiment-defined centrality can be reconstructed without assuming any specific model for the collision dynamics, in both proton-nucleus and nucleus-nucleus systems. The reconstruction is reliable up to about 10\% centrality, and is more accurate for nucleus-nucleus collisions. We perform an application of our procedure to experimental data from all the CERN Large Hadron Collider (LHC) collaborations, from which we extract, in Pb+Pb and $p$+Pb collisions, the corresponding distributions of impact parameter.

A Microscopic Model of the Stokes-Einstein Relation in Arbitrary Dimension

description: The Stokes-Einstein relation (SER) is one of the most robust and widely employed results from the theory of liquids. Yet sizable deviations can be observed for self-solvation, which cannot be explained by the standard hydrodynamic derivation. Here, we revisit the work of Masters and Madden [J. Chem. Phys. 74, 2450-2459 (1981)], who first solved a statistical mechanics model of the SER using the projection operator formalism. By generalizing their analysis to all spatial dimensions and to partially structured solvents, we identify a potential microscopic origin of some of these deviations. We also reproduce the SER-like result from the exact dynamics of infinite-dimensional fluids.

Covariant $W$ Gravity \& its Moduli Space from Gauge Theory

description: In this paper we study arbitrary $W$ algebras related to embeddings of $sl_2$ in a Lie algebra $g$. We give a simple formula for all $W$ transformations, which will enable us to construct the covariant action for general $W$ gravity. It turns out that this covariant action is nothing but a Fourier transform of the WZW action. The same general formula provides a geometrical interpretation of $W$ transformations: they are just homotopy contractions of ordinary gauge transformations. This is used to argue that the moduli space relevant to $W$ gravity is part of the moduli space of $G$-bundles over a Riemann surface.

description: Solid State Nuclear Magnetic Resonance (NMR) experiments allow characterizing the local structure and dynamics of oxide glasses and melts. Thanks to the development of new experiments, it now becomes possible to evidence not only the details of the coordination state of the network formers of glasses but also to characterize the nature of polyatomic molecular motifs extending over several chemical bonds. We present results involving 31P homonuclear experiments that allow description of groups of up to three phosphate units and 27Al/17O heteronuclear that allows evidencing μ3 oxygen bridges in aluminate glasses and rediscussion of the structure of high temperature melts.

description: What if you had the power to ensure that Lots of Copies of your repository's Stuff were Kept Safe -- and discoverable, and retrievable -- from a second, stable, high-profile data point? What if you could automate the process, scaling up to the whole repository, or down to the item level -- replicating it all -- and storing that second archive for free? This talk presents "what came next" after the Naval Postgraduate School Library's innovative project to digitize its entire print-collection of ETDs with Internet Archive, a nonprofit venture based in San Francisco, CA. After taking back the IA's digitized-for-us content to seed our newly-built institutional repository, we began to think about the value of bringing the growing collection back to this popular platform and that making the round-trip back to the original collection in IA would increase its discovery, use and impact. By creation of a new integration between DSpace and the IA, NPS is now able to selectively publish archived publicly-accessible DSpace content to our pre-established Internet Archive collection. Support includes configurable metadata mapping, item creation, update, and, withdraw. Email notification assures that the process can be well monitored by repository staff.
Physical realization of complex dynamical pattern formation in magnetic active feedback rings

description: We report the clean experimental realization of cubic-quintic complex Ginzburg-Landau physics in a single driven, damped system. Four numerically predicted categories of complex dynamical behavior and pattern formation are identified for bright and dark solitary waves propagating around an active magnetic thin film-based feedback ring: (1) periodic breathing; (2) complex recurrence; (3) spontaneous spatial shifting; and (4) intermittency. These nontransient, long lifetime behaviors are observed in microwave spin wave envelopes circulating within a dispersive, nonlinear yttrium iron garnet waveguide operating in a ring geometry where the net losses are directly compensated for via linear amplification on each round trip O(100 ns). The behaviors exhibit periods ranging from tens to thousands of round trip times O($μ$ s) and are stable for 1000s of periods O(ms). We present 10 observations of these dynamical behaviors which span the experimentally accessible ranges of attractive cubic nonlinearity, dispersion, and external field strength that support the self-generation of backward volume spin waves in a four-wave-mixing dominant regime. Three-wave splitting is not explicitly forbidden and is treated as an additional source of nonlinear losses. Each of these long lifetime behaviors of bright solitary waves was previously numerically predicted to be observable. The dynamical pattern formation of dark solitary waves in attractive nonlinearity, however, is entirely novel and is reported for both the periodic breather and complex recurrence behaviors. All behaviors are identified in the group velocity co-moving frame.

description: The study sought to ascertain staff competencies in the planning and establishing of an open repository at the Botswana University of Agriculture and Natural Resources (BUAN). The study used the following critical questions as guide: What knowledge, skills and personal attributes are required in the planning and establishing of a successful open repository in an academic institution?; How significant a role do personal attributes such as attitudes and perceptions play in the planning and establishing of an open repository at BUAN?; and, What measures may be put in place to reinforce the planning and establishing of an open repository at the BUAN? The study adopted a case study approach. The study population consisted of BUAN academics, Library staff, and Information Technology (IT) staff. A number of knowledge sets, skills and personal attributes emerged from the study as being required in the planning and establishing of a successful open repository at BUAN, critical amongst these being knowledge of metadata and metadata standards as well as research data management. An important recommendation emanating from the study related to repository advocacy and outreach among BUAN academics as well as on-going training of library repository staff to keep them abreast of latest repository developments.
