description: The dynamics of the one-dimensional random transverse Ising model with both nearest-neighbor (NN) and next-nearest-neighbor (NNN) interactions is studied in the high-temperature limit by the method of recurrence relations. Both the time-dependent transverse correlation function and the corresponding spectral density are calculated for two typical disordered states. We find that for the bimodal disorder the dynamics of the system undergoes a crossover from a collective-mode behavior to a central-peak one and for the Gaussian disorder the dynamics is complex. For both cases, it is found that the central-peak behavior becomes more obvious and the collective-mode behavior becomes weaker as $K_{i}$ increase, especially when $K_{i}>J_{i}/2$ ($J_{i}$ and $K_{i}$ are exchange couplings of the NN and NNN interactions, respectively). However, the effects are small when the NNN interactions are weak ($K_{i}

description: We study the local flux of electrons and positrons from annihilating Dark Matter (DM), and investigate how its spectrum depends on the choice of DM model and inhomogeneities in the DM distribution. Below a cutoff energy, the flux is expected to have a universal power-law form with an index n ~ -2. The cutoff energy and the behavior of the flux near the cutoff is model dependent. The dependence on the DM host halo profile may be significant at energies E < 100 GeV and leads to softening of the flux, n < -2. There may be additional features at high energies due to the presence of local clumps of DM, especially for models in which the Sommerfeld effect boosts subhalo luminosities. In general, the flux from a nearby clump gives rise to a harder spectrum of electrons and positrons, with an index n > -2. Using the Via Lactea II simulation, we estimate the probability of such subhalo effects in a generic Sommerfeld-enhanced model to be at least 4%, and possibly as high as 15% if subhalos below the simulation's resolution limit are accounted for. We discuss the consequences of these results for the interpretation of the ATIC, PAMELA, HESS, and Fermi data, as well as for future experiments.

description: The ultraviolet and rapidity divergences of transverse-momentum dependent parton distribution functions with lightlike and transverse gauge links is studied, also incorporating a soft eikonal factor. We find that in the light-cone gauge with $q^-$-independent pole prescriptions extra divergences appear which amount, at one-loop, to a cusp-like anomalous dimension. We show that such contributions are absent when the Mandelstam-Leibbrandt prescription is used. In the first case, the soft factor cancels the anomalous-dimension defect, while in the second case its ultraviolet-divergent part reduces to unity.

description: This paper is an introduction to the use of perverse sheaves with positive characteristic coefficients in modular representation theory. In the first part, we survey results relating singularities in finite and affine Schubert varieties and nilpotent cones to modular representations of reductive groups and their Weyl groups. The second part is a brief introduction to the theory of perverse sheaves with an emphasis on the case of positive characteristic and integral coefficients. In the final part, we provide some explicit examples of stalks of intersection cohomology complexes with integral or positive characteristic coefficients in nilpotent cones, mostly in type $A$. Some of these computations might be new.

description: Attention is paid to the production mechanisms of light scalars that reveal their nature. We reveal the chiral shielding of the σ(600) meson. We show that the kaon loop mechanism of the ϕradiative decays, ratified by experiment, points to the four-quark nature of light scalars. We show also that the light scalars are produced in the two photon collisions via four-quark transitions in contrast to the classic P wave tensor q\bar q mesons that are produced via two-quark transitions $γγ\to q\bar q$. The history of spontaneous breaking of symmetry in quantum physics is discussed in Appendix.

description: Polygon representation learning is essential for diverse applications, encompassing tasks such as shape coding, building pattern classification, and geographic question answering. While recent years have seen considerable advancements in this field, much of the focus has been on single polygons, overlooking the intricate inner- and inter-polygonal relationships inherent in multipolygons. To address this gap, our study introduces a comprehensive framework specifically designed for learning representations of polygonal geometries, particularly multipolygons. Central to our approach is the incorporation of a heterogeneous visibility graph, which seamlessly integrates both inner- and inter-polygonal relationships. To enhance computational efficiency and minimize graph redundancy, we implement a heterogeneous spanning tree sampling method. Additionally, we devise a rotation-translation invariant geometric representation, ensuring broader applicability across diverse scenarios. Finally, we introduce Multipolygon-GNN, a novel model tailored to leverage the spatial and semantic heterogeneity inherent in the visibility graph. Experiments on five real-world and synthetic datasets demonstrate its ability to capture informative representations for polygonal geometries. Code and data are available at \href{https://github.com/dyu62/PolyGNN}{$github.com/dyu62/PolyGNN$}.

We show that this methodology is stable, showing good accuracy and a remarkable scale invariance in its solution space. In addition the MDG method is robust, adapting well to various initial-boundary value problems of particular significance in a range of physical and chemical applications. We further show explicitly how to recover the Lagrangian frame (or pathline) solutions.

Gradient formula for the beta-function of 2d quantum field theory

Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We give a non-perturbative proof of a gradient formula for beta functions of two-dimensional quantum field theories. The gradient formula has the form \partial_{i}c = - (g_{ij}+Δg_{ij} +b_{ij})β^{j} where β^{j} are the beta functions, c and g_{ij} are the Zamolodchikov c-function and metric, b_{ij} is an antisymmetric tensor introduced by H. Osborn and Δg_{ij} is a certain metric correction. The formula is derived under the assumption of stress-energy conservation and certain conditions on the infrared behaviour the most significant of which is the condition that the large distance limit of the field theory does not exhibit spontaneously broken global conformal symmetry. Being specialized to non-linear sigma models this formula implies a one-to-one correspondence between renormalization group fixed points and critical points of c.

description: Wearables that constantly collect various sensor data of their users increase the chances for inferences of unintentional and sensitive information such as passwords typed on a physical keyboard. We take a thorough look at the potential of using electromyographic (EMG) data, a sensor modality which is new to the market but has lately gained attention in the context of wearables for augmented reality (AR), for a keylogging side-channel attack. Our approach is based on neural networks for a between-subject attack in a realistic scenario using the Myo Armband to collect the sensor data. In our approach, the EMG data has proven to be the most prominent source of information compared to the accelerometer and gyroscope, increasing the keystroke detection performance. For our end-to-end approach on raw data, we report a mean balanced accuracy of about 76 % for the keystroke detection and a mean top-3 key accuracy of about 32 % on 52 classes for the key identification on passwords of varying strengths. We have created an extensive dataset including more than 310 000 keystrokes recorded from 37 volunteers, which is available as open access along with the source code used to create the given results.

description: Fashion, a highly subjective topic is interpreted differently by all individuals. E-commerce platforms, despite these diverse requirements, tend to cater to the average buyer instead of focusing on edge cases like non-binary shoppers. This case study, through participant surveys, shows that visual search on e-commerce platforms like Amazon, Beagle.Vision and Lykdat, is particularly poor for non-binary clothing items. Our comprehensive quantitative analysis shows that these platforms are more robust to binary clothing inputs. The non-binary clothing items are recommended in a haphazard manner, as observed through negative correlation coefficients of the ranking order. The participants also rate the non-binary recommendations lower than the binary ones. Another intriguing observation is that male raters are more inclined to make binary judgements compared to female raters. Thus it is clear that these systems are not inclusive to the minority, disadvantaged communities of society, like LGBTQ+ people. We conclude with a call to action for the e-commerce platforms to take cognizance of our results and be more inclusive.

description: Excerpts from the report: Within the last 10 years thousands of new settlers have taken up small tracts of land in the undeveloped cut over areas of the Mississippi Delta—the poorly drained wooded lowlands of Louisiana, Mississippi, Arkansas, and Missouri. Here the settlers, most of them cotton farmers from the worn-out hill lands nearby or from the sharecropper cabins of Delta plantations, are clearing the new ground and trying to establish family-size cotton farms. Hungry for land, and lacking opportunities elsewhere, they believe the undeveloped Delta areas offer the opportunities and the fresh start they are seeking. This publication seeks to call attention to the many serious problems, as well as opportunities, that face present and future settlers in the undeveloped cut-over parts of the Mississippi River Delta. Most of the information given here has been taken from recent studies of settlement conditions in the delta of northeastern Louisiana, but some of the conditions disclosed are common to many of the cut-over areas throughout the lower Mississippi River Valley. A digest of the information obtained by these studies is furnished here in nontechnical form. New settlers who have already located in the Delta cut-over areas may find this helpful when studying their present problems and arriving at solutions for them. Farmers who are thinking about moving into these areas should find the publication a useful source of facts and guidance.

description: Ultralight vectors can extract energy and angular momentum from a Kerr black hole (BH) due to superradiant instability, resulting in the formation of a BH-condensate system. In this work, we carefully investigate the evolution of this system numerically with multiple superradiant modes. Simple formulas are obtained to estimate important timescales, maximum masses of different modes, as well as the BH mass and spin at various times. Due to the coexistence of modes with small frequency differences, the BH-condensate system emits gravitational waves with a unique beat signature, which could be directly observed by current and projected interferometers. Besides, the current BH spin-mass data from the binary BH merger events already exclude the vector mass in the range $5\times 10^{-15}\ \mathrm{eV} <μ< 9\times 10^{-12}\ \mathrm{eV}$.

description: Topological winding in non-Hermitian systems are generally associated to the Bloch band properties of lattice Hamiltonians. However, in certain non-Hermitian models topological winding naturally arise from the dynamical evolution of the system and related to a new form of geometric phase. Here we investigate dynamical topological winding in non-Hermitian photonic mesh lattices, where the mean survival time of an optical pulse circulating in coupled fiber loops is quantized and robust against Hamiltonian deformations. The suggested photonic model could provide an experimentally accessible platform for the observation of non-Hermitian dynamical topological windings.

Alkalinity Concentration Swing for Direct Air Capture of Carbon Dioxide

description: We describe a new principle - the Alkalinity Concentration Swing (ACS) - for direct air capture of carbon dioxide driven by concentrating an alkaline solution that has been exposed to the atmosphere and loaded with dissolved inorganic carbon. Upon concentration, the partial pressure of carbon dioxide increases, allowing for extraction and compression. We find that higher concentration factors result in proportionally higher outgassing pressure, and higher initial alkalinity concentrations at the same concentration factor outgas a higher concentration of CO2 relative to the feed solution. We examine two desalination technologies, reverse osmosis and capacitive deionization, as possible implementation for the ACS, and evaluate two simplified corresponding energy models. We compare the ACS to incumbent technologies and make estimates on water, land, and energy requirements for capturing one million tonnes of CO2 per year. We find that estimates for the lower end of the energy range for both reverse osmosis and capacitive deionization approaches are lower than or roughly equal to incumbent direct air capture approaches. For most conditions, we find an inverse relationship between the required energy and water processing volume per million tonnes of CO2. Realizing the ACS requires a simple alkaline aqueous solvent (e.g. potassium alkalinity carrier) and does not require heat as a driving mechanism. More generally, the ACS can be implemented through industrial-scale desalination approaches, meaning current technology could be leveraged for scale-up.

Non-uniform real estate taxation: a case study of the consequences
Creators: name: Ward, Laurence William Percy
Publisher: name: University of British Columbia
Year: 2011

description: This thesis examines the general subject of real estate property taxation and the specific problem of evaluating the consequences of certain taxation policies. The administration of real estate property taxation in North America is examined by means of a literature review. Particular emphasis is placed on the criticism that has been directed at the tax on the basis of administration and the nature of the tax. The problem of non-uniformity of taxation and its consequences is examined in great detail. The sources of the problem and proposed remedies are reviewed and the methods of analysis are subjected to a critical analysis. The economic characteristics of real estate property taxes are analyzed, drawing particular attention to the difference between the effects of a tax on land and a tax on improvements. Taxes on land and improvements are evaluated in terms of their effects on property values, rents, investment decisions and development. Land assessment practices in a residential-business transition zone adjacent to the central business district in Regina are examined in detail, relating the assessed values to estimated market values. Assessed land values, expressed as percentages of estimated market value in the transition zone are compared to assessed land values in developing residential subdivisions also expressed as a percentage of the estimated market value. Land assessment rates in the transition zone are adjusted to approximately the same percentage of estimated market value as the land assessment rates in the developing subdivisions and the effect of this change on the distribution of taxes is calculated. The effects of the redistribution of taxes are evaluated using economic and real estate property taxation theories. The examination is limited to a qualitative analysis due to the lack of data which prevents the formulation of mathematical models that are capable of making quantitative predictions. In conclusion, although the methods employed to analyze the under- assessment of land in one part of the city do provide some indication of the consequences of the policy, the inability to make quantitative judgments limits their application as policy implementation tools.

description: It is well known that a non-universal $Z^\prime$ induces tree-level FCNC which are severely constrained by experiment, most notably meson mixing. We point out that there is a class of models, with a down-quark mass matrix of the Georgi-Jarlskog form, in which the FCNC in the down-type quark sector vanish or are strongly suppressed. The largest FCNC in these models would occur in the $tc$ transition with a strength comparable to $V_{ts}$.

description: Context: Despite the observed signs of large impacts on the surface of Ceres, there is no confirmed collisional family associated with this dwarf planet. After a dynamical and photometric study, a sample of 156 asteroids was proposed as candidate members of a Ceres collisional family. Aims: Our main objective is to study the connection between Ceres and a total of 14 observed asteroids among the candidate's sample to explore their genetic relationships with Ceres. Methods: We obtained visible spectra of these 14 asteroids using the OSIRIS spectrograph at the 10.4 m Gran Telescopio Canarias(GTC). We computed spectral slopes in two different wavelength ranges, from 0.49 to 0.80μm and from 0.80 to 0.92μm, to compare the values obtained with those on Ceres' surface previously computed using the Visible and Infrared Spectrometer (VIR) instrument onboard the NASA Dawn spacecraft. We also calculated the spectral slopes in the same range for ground-based observations of Cerescollected from the literature. Results: We present the visible spectra and the taxonomy of 14 observed asteroids. We found that only two of the asteroids are spectrally compatible with Ceres' surface. Further analysis of those two asteroids indicates that they are spectrally young and thus less likely to be members of the Ceres family. Conclusions: All in all, our results indicate that most of the 14 observed asteroids are not likely to belong to a Ceres collisional family. Despite two of them being spectrally compatible with the young surface of Ceres, further evaluation is needed to confirm or reject their origin from Ceres.

Transfer in serial learning as a function of interlist positional relations
Creators: name: Whitmore, Sally Jean
Publisher: name: University of British Columbia

description: Transfer in serial learning as a function of inter-list positional relations was examined in a serial to serial transfer paradigm. After learning a 16-adjective serial list to a criterion of two consecutive perfect recitations, 128 Ss, were given ten trials on a l6-adjective transfer task. There were four conditions of transfer defined by the positional relationship of Items between successive lists. First-, second-, and fourth-order derived list conditions and a control condition were used. Half of the experimental Ss were instructed as to the positional relationship between the lists while the remaining Ss were given no positional Information. The results indicated significant positive transfer in the DL₁ and DL₄ groups when compared to the control group. DL₂ performance was slightly superior to performance of the control group but this difference did not approach significance. Performance of instructed Ss was found to be significantly better than performance of non-instructed Ss. The instructions variable was not found to have a differential effect among conditions. The results were interpreted as being Incompatible with either the sequential or the ordinal-position hypothesis of serial learning, but as evidence in support of a relative ordinal-position hypothesis.
title: Nature and Norfolk : The History of the Norfolk Botanical Garden

description: If what they say is true, that first impressions are always the most important, then the city of Norfolk, Virginia could impress anyone. The Norfolk Botanical Garden began as approximately 30 acres surrounding Mirror Lake, adjacent to the proposed Norfolk Municipal Airport in 1938. Today the Garden consists of 158 acres that include a variety of garden styles, manmade canals, and extensive educational facilities. It serves as the first and last view visitors have of Norfolk. The Norfolk Botanical Garden is an example of interdisciplinary co-operation. Biology, urban planning, landscape architecture, and various political involvements are all expressed within the Garden's design and purpose. It provides a physical representation of what can occur when urban planners and city officials take the time to create an environment worthy of its form and function. The Garden is the balance between two necessary, and often opposing, forces within a city: the need for modem air travel and the need for open spaces in the community. By juxtaposing these two competitive functions, Norfolk has visually balanced technology and community, man and nature. This thesis will discuss the evolution of the Norfolk Azalea Garden started in 1938 to the current Norfolk Botanical Garden. Special attention will be given to the early involvement of the Works Projects Administration and the social and racial implications present in the Garden's creation. Secondly, this thesis will provide documentation of all the Garden's resources. Lastly, this thesis will address the significance of the Norfolk Botanical Garden within the context of urban planning. Factors including the Garden's location and continued growth in size and function will be analyzed. Recently, Norfolk Botanical Garden was nominated and approved to be listed on the National Register of Historic Places. This honor provides a strong basis on which to discuss the trend towards preservation of historic landscapes. The impact of this nomination will further the Garden's function and provide new means to acknowledge local history.

description: We present new observational results that conclude that the nearby radio galaxy B2 0722+30 is one of the very few known disc galaxies in the low-redshift Universe that host a classical double-lobed radio source. In this paper we use HI observations, deep optical imaging, stellar population synthesis modelling and emission-line diagnostics to study the host galaxy, classify the Active Galactic Nucleus and investigate environmental properties under which a radio-loud AGN can occur in this system. Typical for spiral galaxies, B2 0722+30 has a regularly rotating gaseous disc throughout which star formation occurs. Dust heating by the ongoing star formation is likely responsible for the high infrared luminosity of the system. The optical emission-line properties of the central region identify a Low Ionization Nuclear Emission-line Region (LINER)-type nucleus with a relatively low [OIII] luminosity, in particular when compared with the total power of the Fanaroff & Riley type-I radio source that is present in this system. This classifies B2 0722+30 as a classical radio galaxy rather than a typical Seyfert galaxy. The environment of B2 0722+30 is extremely HI-rich, with several nearby interacting galaxies. We argue that a gas-rich interaction involving B2 0722+30 is a likely cause for the triggering of the radio-AGN and/or the fact that the radio source managed to escape the optical boundaries of the host galaxy.

Detecting quantum resources in a semi-device independent framework

description: We investigate whether one can detect the presence of a quantum resource in some operational task or equivalently whether every quantum resource provides an advantage over its free counterpart in some black box scenarios where one does not have much information about the devices. For any dimension $d$, we find that for any resource theory with less than $d^2$ number of linearly independent free states or free operations, there exist correlations that can detect the presence of a quantum resource. For this purpose, we introduce the framework for detecting quantum resources semi-device independently by considering the prepare-and-measure scenario with the restriction on the dimension of the quantum channel connecting the preparation box with the measurement box. We then explicitly construct witnesses to observe the presence of various quantum resources. We expect these results will open avenues for detecting and finding uses of quantum resources in general operational tasks.

description: Secure installation of Internet of Things (IoT) devices requires configuring access control correctly for each device. In order to enable correct configuration the Manufacturer Usage Description (MUD) has been developed by Internet Engineering Task Force (IETF) to automate the protection of IoT devices by micro-segmentation using dynamic access control lists. The protocol defines a conceptually straightforward method to implement access control upon installation by providing a list of every authorized access for each device. This access control list may contain a few rules or hundreds of rules for each device. As a result, validating these rules is a challenge. In order to make the MUD standard more usable for developers, system integrators, and network operators, we report on an interactive system called MUD-Visualizer that visualizes the files containing these access control rules. We show that, unlike manual analysis, the level of the knowledge and experience does not affect the accuracy of the analysis when MUD-Visualizer is used, indicating that the tool is effective for all participants in our study across knowledge and experience levels.

description: Only a few wide-orbit planets around old stars have been detected, which limits our statistical understanding of this planet population. Following the systematic search for planetary anomalies in microlensing events found by the Korea Microlensing Telescope Network (KMTNet), we present the discovery and analysis of three events that were initially thought to contain wide-orbit planets. The anomalous feature in the light curve of OGLE-2018-BLG-0383 is caused by a planet with mass ratio $q=2.1\times 10^{-4}$ and a projected separation $s=2.45$. This makes it the lowest mass-ratio microlensing planet at such wide orbits. The other two events, KMT-2018-BLG-0998 and OGLE-2018-BLG-0271, are shown to be stellar binaries ($q>0.1$) with rather close ($s<1$) separations. We briefly discuss the properties of known wide-orbit microlensing planets and show that the survey observations are crucial in discovering and further statistically constraining such a planet population.
