description: The properties of Hopf star operations and twisted Hopf stars operations on quantum groups are discussed in relation with the theory of representations (star representations). Invariant Hermitian sesquilinear forms (scalar products) on modules or module-algebras are then defined and analyzed. Particular attention is paid to scalar products that can be associated with the Killing form (when it exists) or with the left (or right) invariant integrals on the quantum group. Our results are systematically illustrated in the case of a family of non semi-simple and finite dimensional quantum groups that are obtained as Hopf quotients of the quantum enveloping algebra U_q(sl(2,C)), q being an N-th root of unity. Many explicit results concerning the case N=3 are given. We also mention several physical motivations for the present work: conformal field theory, spin chains, integrable models, generalized Yang-Mills theory with quantum group action and the search for finite quantum groups symmetries in particle physics.

description: Business Improvement Districts (BIDs) have been used as an instrument to revitalize, strengthen and recover commercial districts in cities in North America for several decades. In May 2015, the Chilean government started a pilot program: Commercial District Enhancement Program (Fortalecimiento de Barrios Comerciales, FBC), which aims to implement BIDs in several cities. The BID model is based on an increase in property taxes to generate extra revenues that are appointed to provide or complement services such as sanitation, security, and marketing in a particular district. Based on data collected through interviews and using NYC as a point of comparison, this thesis analyzed the approach of the Chilean BID model in order to inform key issues, such as the need for strong associations, access to permanent revenues, and services provided. Notwithstanding, results show the Chilean pilot program is it currently stands to be unsuccessful; the program is not designed to address the long-term goal economically sustainable commercial districts.

description: After decades of massive digitisation, an unprecedented amount of historical documents is available in digital format, along with their machine-readable texts. While this represents a major step forward with respect to preservation and accessibility, it also opens up new opportunities in terms of content mining and the next fundamental challenge is to develop appropriate technologies to efficiently search, retrieve and explore information from this 'big data of the past'. Among semantic indexing opportunities, the recognition and classification of named entities are in great demand among humanities scholars. Yet, named entity recognition (NER) systems are heavily challenged with diverse, historical and noisy inputs. In this survey, we present the array of challenges posed by historical documents to NER, inventory existing resources, describe the main approaches deployed so far, and identify key priorities for future developments.

description: We apply the geometric quantization method with real polarizations to the quantization of a symplectic torus. By quantizing with half-densities we canonically associate to the symplectic torus a projective Hilbert space and prove that the projective factor is expressible in terms of the Maslov-Kashiwara index. As in the quantization of a linear symplectic space, we have two ways of resolving the projective ambiguity: (i) by introducing a metaplectic structure and using half-forms in the definition of the Hilbert space; (ii) by choosing a 4-fold cover of the Lagrangian Grassmannian of the linear symplectic space covering the torus. We show that the Hilbert space constructed through either of these approaches realizes a unitary representation of the integer metaplectic group.

description: Multispectral imaging plays a critical role in a range of intelligent transportation applications, including advanced driver assistance systems (ADAS), traffic monitoring, and night vision. However, accurate visible and thermal (RGB-T) image registration poses a significant challenge due to the considerable modality differences. In this paper, we present a novel joint Self-Correlation and Cross-Correspondence Estimation Framework (SC3EF), leveraging both local representative features and global contextual cues to effectively generate RGB-T correspondences. For this purpose, we design a convolution-transformer-based pipeline to extract local representative features and encode global correlations of intra-modality for inter-modality correspondence estimation between unaligned visible and thermal images. After merging the local and global correspondence estimation results, we further employ a hierarchical optical flow estimation decoder to progressively refine the estimated dense correspondence maps. Extensive experiments demonstrate the effectiveness of our proposed method, outperforming the current state-of-the-art (SOTA) methods on representative RGB-T datasets. Furthermore, it also shows competitive generalization capabilities across challenging scenarios, including large parallax, severe occlusions, adverse weather, and other cross-modal datasets (e.g., RGB-N and RGB-D).

description: In this dissertation I provide a detailed analysis of the role played by the Tachikawa-ryu in the development of Japanese esoteric Buddhist doctrine during the medieval period (900-1200). In doing so, I seek to challenge currently held, inaccurate views of the role played by this tradition in the history of Japanese esoteric Buddhism and Japanese religion more generally. The Tachikawa-ryu, which has yet to receive sustained attention in English-language scholarship, began in the twelfth century and later came to be denounced as heretical by mainstream Buddhist institutions. The project will be divided into four sections: three of these will each focus on a different chronological stage in the development of the Tachikawa-ryu, while the introduction will address the portrayal of this tradition in twentieth-century scholarship.

description: We use holography to develop a physical picture of the real-time evolution of the spinodal instability of a four-dimensional, strongly-coupled gauge theory with a first-order, thermal phase transition. We numerically solve Einstein's equations to follow the evolution, in which we identify four generic stages: A first, linear stage in which the instability grows exponentially; a second, non-linear stage in which peaks and/or phase domains are formed; a third stage in which these structures merge; and a fourth stage in which the system finally relaxes to a static, phase-separated configuration. On the gravity side the latter is described by a static, stable, inhomogeneous horizon. We conjecture and provide evidence that all static, non-phase separated configurations in large enough boxes are dynamically unstable. We show that all four stages are well described by the constitutive relations of second-order hydrodynamics that include all second-order gradients that are purely spatial in the local rest frame. In contrast, a Müller-Israel-Stewart-type formulation of hydrodynamics fails to provide a good description for two reasons. First, it misses some large, purely-spatial gradient corrections. Second, several second-order transport coefficients in this formulation, including the relaxation times $τ_π$ and $τ_Π$, diverge at the points where the speed of sound vanishes.

description: We consider practical aspects of reconstructing planar curves with prescribed Euclidean or affine curvatures. These curvatures are invariant under the special Euclidean group and the equi-affine groups, respectively, and play an important role in computer vision and shape analysis. We discuss and implement algorithms for such reconstruction, and give estimates on how close reconstructed curves are relative to the closeness of their curvatures in appropriate metrics. Several illustrative examples are provided.

description: We present the derivation of a new model to describe neutron spin echo spectroscopy and quasi-elastic neutron scattering data on liposomes. We compare the new model with existing approaches and benchmark it with experimental data. The analysis indicates the importance of including all major contributions into modeling of the intermediate scattering function. Simultaneous analysis of the experimental data on lipids with full contrast and tail contrast matched samples, reveals highly confined lipid tail motion. A comparison of their dynamics demonstrates the statistical independ-ence of tail-motion and height-height correlation of the membrane. A more detailed analysis indi-cates that lipid tails are subject to relaxations in a potential with cylindrical symmetry, in addition to the undulation and diffusive motion of the liposome. Despite substantial differences in the chemis-try of the fatty acid tails, the observation indicates a universal behavior. The analysis of partially deuterated systems confirms the strong contribution of the lipid tail to the intermediate scattering function. Within the time range from 5 to 100 ns, the intermediate scattering function can be de-scribed by the height-height correlation function. The existence of the fast-localized tail motion and the contribution of slow translational diffusion of liposomes determines the intermediate scattering function for t < 5 ns and t > 100 ns, respectively. Taking into account the limited time window lowers the bending moduli by a factor of 1.3 (DOPC) to 2 (DMPC) compared to the full range.

We establish a logarithmic Harnack inequality for the transition semigroup $\{P(t)\}_{t\geq 0}$ associated with the stochastic problem above, under less restrictive conditions than those considered in the literature. Some applications to these inequalities are also shown.

description: Entwined space-time paths are bound pairs of trajectories which are traversed in opposite directions with respect to macroscopic time. In this paper we show that ensembles of entwined paths on a discrete space-time lattice are simply described by coupled difference equations which are discrete versions of the Dirac equation. There is no analytic continuation, explicit or forced, involved in this description. The entwined paths are `self-quantizing'. We also show that simple classical stochastic processes that generate the difference equations as ensemble averages are stable numerically and converge at a rate governed by the details of the stochastic process. This result establishes the Dirac equation in one dimension as a phenomenological equation describing an underlying classical stochastic process in the same sense that the Diffusion and Telegraph equations are phenomenological descriptions of stochastic processes.

Creating a 'Cultural Innovation District' at Lincoln Center

description: Lincoln Center and its surrounding area, including the Special Lincoln Square District, Special Clinton District, and Theater Subdistrict, hold one-third of all New York City performing arts spaces, making it the densest collection of performing arts spaces in the world. Despite this high concentration, the area lacks supporting spaces integral to the success of arts and culture activities. Recognizing this need, the Lincoln Center Development Project (LCDP) is producing a technical report on the benefits and feasibility of creating the Amsterdam Corridor Cultural Innovation District (ACCID). The ACCID will connect the high concentration of existing performing arts spaces with its surrounding neighborhoods. It will produce new support spaces to match this high concentration, as well as incorporate programming into existing spaces that creates value for the community. The primary goal is to provide institutional support for the neighborhood’s local performing and fine arts communities through development and stewardship of physical and social infrastructure. Beyond fostering the arts, the ACCID is also intended to drive innovation. How can Lincoln Center create new and expand existing cultural spaces in order to activate innovation and arts production? It is recommended that LCDP encourage production of rehearsal studios, which are essential to the creative process and can be designed to accommodate a variety of disciplines. It is also recommended that LCDP factor affordability and a variety of open hours into operations, develop a comprehensive plan, create a Liaison position for the district, curate programming under three categories (education, collaboration, and incubation), develop a community engagement strategy, and position the ACCID as a force against artist displacement and inequity. The ACCID will have the potential to make an impact beyond its boundaries and promote the performing and fine arts across all of New York City. The prosperity of this sector is beneficial to the NYC arts community as a whole. Moreover, by establishing the ACCID, Lincoln Center will not just develop spaces, but create long-lasting connections with local organizations and enable the proximity necessary for artists to collaborate and create.
Parity-odd Parton Distribution Functions from $θ$-Vacuum

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Quantum chromodynamics is a fundamental non-abelian gauge theory of strong interactions. The physical quantum chromodynamics vacuum state, $|θ\rangle$, is a linear superposition of the $n$-vacua states with different topological numbers. Because of the configuration of the gauge fields, the tunneling events can induce the local parity-odd domains. Those interactions that occur in these domains can be affected by these effects. Considering the hadron (nucleon) system, we introduce the parity-odd parton distribution functions in order to describe the parity-odd structures inside the hadron in this paper. We obtain 8 parity-odd parton distribution functions at leading twist for spin-1/2 hadrons and present properties of these parton distribution functions. By introducing the parity-odd quark-quark correlator, we find the parity-odd effects vanish from the macroscopic point of view. Since the parity-odd effects are confined in small domains, we consider the high energy semi-inclusive deeply inelastic scattering process to investigate these effects by calculating the single spin asymmetries.

description: The Burau representation is a natural action of the braid group B_n on the free Z[t,t^{-1}]-module of rank n-1. It is a longstanding open problem to determine for which values of n this representation is faithful. It is known to be faithful for n=3. Moody has shown that it is not faithful for n>8 and Long and Paton improved on Moody's techniques to bring this down to n>5. Their construction uses a simple closed curve on the 6-punctured disc with certain homological properties. In this paper we give such a curve on the 5-punctured disc, thus proving that the Burau representation is not faithful for n>4.

description: Ongoing experimental efforts to measure with unprecedented precision electron-capture probabilities challenges the current theoretical models. The short range of the weak interaction necessitates an accurate description of the atomic structure down to the nucleus region. A recent electron-capture modeling has been modified in order to test the influence of three different atomic descriptions on the decay and shaking probabilities. To this end, a specific atomic modeling was developed in the framework of the relativistic density-functional theory, exploring several exchange-correlation functionals and self-interaction-corrected models. It was found that the probabilities of total shaking, tested on both photoionization and electron-capture processes, depend strongly on the accuracy of the atomic modeling. Predictions of capture probabilities have been compared with experimental values evaluated from available published data for different radionuclides from $^{7}$Be to $^{138}$La. New high-precision measurements are strongly encouraged because the accuracy of the current experimental values is insufficient to test the models beyond the inner shells.

description: Self-propelled jumping of two polymeric droplets on superhydrophobic surfaces is investigated by three-dimensional direct numerical simulations. Two identical droplets of a viscoelastic fluid slide, meet and coalesce on a surface with contact angle 180 degrees. The droplets are modelled by the Giesekus constitutive equation, introducing both viscoelasticity and a shear-thinning effects. The Cahn-Hilliard Phase-Field method is used to capture the droplet interface. The simulations capture the spontaneous coalescence and jumping of the droplets. The effect of elasticity and shear-thinning on the coalescence and jumping is investigated at capillary-inertial and viscous regimes. The results reveal that the elasticity of the droplet changes the known capillary-inertial velocity scaling of the Newtonian drops at large Ohnesorge numbers; the resulting viscoelastic droplet jumps from the surface at larger Ohnesorge numbers than a Newtonian drop, when elasticity gives rise to visible shape oscillations of the merged droplet. The numerical results show that polymer chains are stretched during the coalescence and prior to the departure of two drops, and the resulting elastic stresses at the interface induce the jumping of the liquid out of the surface. This study shows that viscoelasticity, typical of many biological and industrial applications, affects the droplet behaviour on superhydrophobic and self-cleaning surfaces.

description: We present Contingency Model Predictive Control (CMPC), a novel and implementable control framework which tracks a desired path while simultaneously maintaining a contingency plan -- an alternate trajectory to avert an identified potential emergency. In this way, CMPC anticipates events that might take place, instead of reacting when emergencies occur. We accomplish this by adding an additional prediction horizon in parallel to the classical receding MPC horizon. The contingency horizon is constrained to maintain a feasible avoidance solution; as such, CMPC is selectively robust to this emergency while tracking the desired path as closely as possible. After defining the framework mathematically, we demonstrate its effectiveness experimentally by comparing its performance to a state-of-the-art deterministic MPC. The controllers drive an automated research platform through a left-hand turn which may be covered by ice. Contingency MPC prepares for the potential loss of friction by purposefully and intuitively deviating from the prescribed path to approach the turn more conservatively; this deviation significantly mitigates the consequence of encountering ice.

description: The mechanism underlying the divergence of perturbation theory is exposed. This is done through a detailed study of the violation of the hypothesis of the Dominated Convergence Theorem of Lebesgue using familiar techniques of Quantum Field Theory. That theorem governs the validity (or lack of it) of the formal manipulations done to generate the perturbative series in the functional integral formalism. The aspects of the perturbative series that need to be modified to obtain a convergent series are presented. Useful tools for a practical implementation of these modifications are developed. Some resummation methods are analyzed in the light of the above mentioned mechanism.

description: This study provides an overview of existing approaches and methods for assessing the environmental impacts of trade and trade-related activities. It considers both approaches that are tailored to the assessment of trade- environment linkages and more generic approaches for environmental assessment and analyzes their respective usability in the context of trade-related development cooperation. The study thereby aims to contribute to a more extensive use of such tools, while improving the practice and application of environmental assessments of trade-related policies and programs. In doing so, the study will complement the existing study on the assessment of the socio- economic impacts from trade carried out by the Overseas Development Institute (ODI)1. The study is divided into two parts. Part I begins with a brief discussion on trade-related development cooperation followed by a short overview of the debate on trade, development and the environment. Next it provides an overview of existing approaches to conceptualizing environmental impacts from trade-related activities. After this, it provides a general introduction to impact assessment (IA) and the assessment of environmental impacts in this context. It closes with a brief overview of the assessment of environmental aspects in German development cooperation. Part II provides a more detailed review of existing frameworks and methods for assessing the environmental impacts from trade-related policies and programs.

description: A key requirement in studies of endemic vector-borne or zoonotic disease is an estimate of the spatial variation in vector or reservoir host abundance. For many vector species, multiple indices of abundance are available, but current approaches to choosing between or combining these indices do not fully exploit the potential inferential benefits that might accrue from modelling their joint spatial distribution. Here, we develop a class of multivariate generalized linear geostatistical models for multiple indices of abundance. We illustrate this novel methodology with a case study on Norway rats in a low-income urban Brazilian community, where rat abundance is likely risk factor for human leptospirosis. We combine three indices of rat abundance to draw predictive inferences on a spatially continuous latent process, rattiness, that acts as a proxy for abundance. We show how to explore the association between rattiness and spatially varying environmental factors, evaluate the relative importance of each of the three contributing indices and assess the presence of residual, unexplained spatial variation, and identify rattiness hotspots. The proposed methodology is applicable more generally as a tool for understanding the role of vector or reservoir host abundance in predicting spatial variation in the risk of human disease.

description: Characterizing entanglement in all but the simplest case of a two qubit pure state is a hard problem, even understanding the relevant experimental quantities that are related to entanglement is difficult. It may not be necessary, however, to quantify the entanglement of a state in order to quantify the quantum information processing significance of a state. It is known that the fully entangled fraction has a direct relationship to the fidelity of teleportation maximized under the actions of local unitary operations. In the case of two qubits we point out that the fully entangled fraction can also be related to the fidelities, maximized under the actions of local unitary operations, of other important quantum information tasks such as dense coding, entanglement swapping and quantum cryptography in such a way as to provide an inclusive measure of these entanglement applications. For two qubit systems the fully entangled fraction has a simple known closed-form expression and we establish lower and upper bounds of this quantity with the concurrence. This approach is readily extendable to more complicated systems.

Creating a Culture of the Deserving: African American  Students’ Experiences in Minority Recruitment Programs

description: High-achieving African American students are not immune to the issues that underlie racial inequalities in school achievement. There is much to learn from these students in terms of how they navigate schools and achieve according to conventional standards. Further, serious questions remain about the social and racial costs to being constructed as high-achieving against broader narratives of African American students as deficient. This qualitative inquiry uses participant interviews and document analysis to explore the Discourses on achievement and leadership produced by minority recruitment programs and the students who participate in them. Specifically, the research uses critical discourse tools to look at the narratives produced both by African American students and by (and through) program documents. It seeks to understanding where these narratives converge and where there might be tension. This research is conducted by incorporating a socio-cultural literacy and critical race theory framework.
      This dissertation study is at the intersection of equity and access; it problematizes progressive arguments against a segregated curriculum for high-achieving students by invoking a social justice argument in favor of leveling the playing field for traditionally marginalized students, specifically African Americans. Much of the existing literature on high achievement and African Americans takes place in traditional classrooms. Glaringly absent from the literature on achievement are the ways in which some high-performing students of color are positioned to succeed in competitive, non-school environments. Specifically, I look at minority recruitment programs because these programs teach a particular type of literacy. The study explores the degree to which students’ home literacies are being honored.
      Findings indicate that students’ perspectives on achievement were much more critical than those of the programs with students overtly challenging meritocracy. Students were less critical of leadership, and both programs and students offered views that privileged particular literacies of leadership. The researcher offers recommendations for MRPs that calls for programs to involve students in more critical inquiries through the use of a Critical Race English education lens.

description: Emotion recognition is a key attribute for artificial intelligence systems that need to naturally interact with humans. However, the task definition is still an open problem due to the inherent ambiguity of emotions. In this paper, a novel Bayesian training loss based on per-utterance Dirichlet prior distributions is proposed for verbal emotion recognition, which models the uncertainty in one-hot labels created when human annotators assign the same utterance to different emotion classes. An additional metric is used to evaluate the performance by detection test utterances with high labelling uncertainty. This removes a major limitation that emotion classification systems only consider utterances with labels where the majority of annotators agree on the emotion class. Furthermore, a frequentist approach is studied to leverage the continuous-valued "soft" labels obtained by averaging the one-hot labels. We propose a two-branch model structure for emotion classification on a per-utterance basis, which achieves state-of-the-art classification results on the widely used IEMOCAP dataset. Based on this, uncertainty estimation experiments were performed. The best performance in terms of the area under the precision-recall curve when detecting utterances with high uncertainty was achieved by interpolating the Bayesian training loss with the Kullback-Leibler divergence training loss for the soft labels. The generality of the proposed approach was verified using the MSP-Podcast dataset which yielded the same pattern of results.
