description: The XXZ open spin chain with general integrable boundary conditions is shown to possess a q-deformed analogue of the Onsager's algebra as fundamental non-abelian symmetry which ensures the integrability of the model. This symmetry implies the existence of a finite set of independent mutually commuting nonlocal operators which form an abelian subalgebra. The transfer matrix and local conserved quantities, for instance the Hamiltonian, are expressed in terms of these nonlocal operators. It follows that Onsager's original approach of the planar Ising model can be extended to the XXZ open spin chain.

description: The latest development in determining the density dependence of the nuclear symmetry energy using heavy-ion collisions is reviewed. Within the IBUU04 version of an isospin- and momentum-dependent transport model using a modified Gogny effective interaction, recent experimental data from NSCL/MSU on isospin diffusion are found to be consistent with a nuclear symmetry energy of $E_{sym}(ρ)\approx 31.6(ρ/ρ_{0})^{1.05}$ at subnormal densities. Predictions on several observables sensitive to the density dependence of the symmetry energy at supranormal densities accessible at GSI and the planned Rare Isotope Accelerator (RIA) are also made.

description: Galaxy mergers are predicted to trigger accretion onto the central supermassive black holes, with the highest rates occurring during final coalescence. Previously, we have shown elevated rates of both optical and mid-IR selected active galactic nuclei (AGN) in post-mergers, but to date the prevalence of X-ray AGN has not been examined in the same systematic way. We present XMM-Newton data of 43 post-merger galaxies selected from the Sloan Digital Sky Survey along with 430 non-interacting control galaxies matched in stellar mass, redshift, and environment in order to test for an excess of hard X-ray (2-10 keV) emission in post-mergers attributable to triggered AGN. We find 2 X-ray detections in the post-mergers (4.7^{+9.3}_{-3.8}%) and 9 in the controls (2.1^{+1.5}_{-1.0}%), an excess of 2.22^{+4.44}_{-2.22}, where the confidence intervals are 90%. While we therefore do not find statistically significant evidence for an X-ray AGN excess in post-mergers (p = 0.26), we find a factor of ~17 excess of mid-IR AGN in our sample, consistent with past work and inconsistent with the observed X-ray excess (p = 2.7 x 10^{-4}). Dominant, luminous AGN are therefore more frequent in post-mergers, and the lack of a comparable excess of 2-10 keV X-ray AGN suggests that AGN in post-mergers are more likely to be heavily obscured. Our results are consistent with the post-merger stage being characterised by enhanced AGN fueling, heavy AGN obscuration, and more intrinsically luminous AGN, in line with theoretical predictions.

description: Weather-based contingent claims typically rely on a cumulative index of the weather variable. Frequently, the index is weighted to reflect the importance of timing in a weather-production relationship. This article reviews alternative optimization methods and apply criteria for selecting among them to obtain an optimal and robust distribution of weights.

description: Nonlocality of two-mode states of light is addressed by means of CHSH inequality based on displaced on/off photodetection. Effects due to non-unit quantum efficiency and nonzero dark counts are taken into account. Nonlocality of both balanced and unbalanced superpositions of few photon-number states, as well as that of multiphoton twin beams, is investigated. We find that unbalanced superpositions show larger nonlocality than balanced one when noise affects the photodetection process. De-Gaussification by means of (inconclusive) photon subtraction is shown to enhance nonlocality of twin beams in the low energy regime. We also show that when the measurement is described by a POVM, rather than a set of projectors, the maximum achievable value of the Bell parameter in the CHSH inequality is decreased, and is no longer given by the Cirel'son bound.

Mean-Field Theories for Depinning and their Experimental Signatures

description: Mean-field theory is an approximation replacing an extended system by a few variables. For depinning of elastic manifolds, these are the position of its center of mass $u$, and the statistics of the forces $F(u)$. There are two proposals to model the latter: as a random walk (ABBM model), or as uncorrelated forces at integer $u$ (discretized particle model, DPM). While for many experiments ABBM (in the literature misleadingly equated with mean-field theory) makes quantitatively correct predictions, the microscopic disorder force-force correlations cannot grow linearly, and thus unboundedly as a random walk. Even the effective (renormalized) disorder forces which do so at small distances are bounded at large distances. We propose to model forces as an Ornstein Uhlenbeck process. The latter behaves as a random walk at small scales, and is uncorrelated at large ones. By connecting to results in both limits, we solve the model largely analytically, allowing us to describe in all regimes the distributions of velocity, avalanche size and duration. To establish experimental signatures of this transition, we study the response function, and the correlation function of position $u$, velocity $\dot u$ and forces $F$ under slow driving with velocity $v>0$. While at $v=0$ force or position correlations have a cusp at the origin, this cusp is rounded at a finite driving velocity. We give a detailed analytic analysis for this rounding by velocity, which allows us, given experimental data, to extract the time-scale of the response function, and to reconstruct the force-force correlator at $v=0$. The latter is the central object of the field theory, and as such contains detailed information about the universality class in question. We test our predictions by careful numerical simulations extending over up to ten orders in magnitude.

description: Although differences in environmental stringency have been given as a reason for the growth of the livestock sectors, particularly hogs, in non-traditional production regions, there is little empirical evidence to support the existence of pollution havens. This paper uses the number of large farm as the dependent variable instead of state-level inventory data and also develops an environmental regulatory stringency measure for each state over approximately a decade and carries out a rigorous panel data analysis. After controlling for all other important location determinants, we find that stringent environmental regulations are one of the most important repellents of large hog farms in the United States.

Single-particle dynamics of the Anderson model: a two-self-energy description within the numerical renormalization group approach

description: Single-particle dynamics of the Anderson impurity model are studied using both the numerical renormalization group (NRG) method and the local moment approach (LMA). It is shown that a 'two-self-energy' description of dynamics inherent to the LMA, as well as a conventional 'single-self-energy' description, arise within NRG; each yielding correctly the same local single-particle spectrum. Explicit NRG results are obtained for the broken symmetry spectral constituents arising in a two-self-energy description, and the total spectrum. These are also compared to analytical results obtained from the LMA as implemented in practice. Very good agreement between the two is found, essentially on all relevant energy scales from the high-energy Hubbard satellites to the low-energy Kondo resonance.

description: Trematodes in family Echinostomatidae (Looss 1899) are common complex life cycle parasites of both humans and wildlife. The work in this thesis aimed to further evince the diversity of these parasites, in addition to exploring the effects of co-exposure on infection outcomes and investigating the host-seeking behavior of echinostome larvae. These aspects of diversity, co-exposure, and behavior can all have important impacts on parasite transmission. In chapter 1, three genetic markers, ND1, ITS2, and 28S, were utilized to further elucidate the diversity of echinostomes in the Midwestern United States. A subset of snail first intermediate hosts were also sequenced offering insight into parasite host range and specificity. Results indicate that there is a greater diversity of echinostomes in the Midwest than previously appreciated and we suggest that echinostome evolution is often driven by the first intermediate host. In chapter 2, the snail Planorbella trivolvis was exposed to two of its echinostome parasites, Echinostoma trivolvis and Echinoparyphium lineage 3, to evaluate the relative competitive dominance of these two parasites, and to investigate the effects of co-exposure timing on infection outcomes. These parasites exhibit strong priority effects and snails are often infected with the echinostome they were first exposed to, even though Echinostoma trivolvis exhibited competitive dominance to Echinoparyphium. The study in chapter 3 was aimed at determining whether Echinostoma caproni cercariae exposure timing would alter infection outcomes of the human parasite, Schistosoma mansoni. Subtle effects of Echinostoma caproni cercariae exposure timing on Schistosoma mansoni infection prevalence and cercarial shedding were identified. Chapter 4 investigated whether the echinostomes, Echinostoma trivolvis and Echinoparyphium lineage 3, chose their Planorbella trivolvis snail hosts based on echinostome infection status. While Echinostoma trivolvis and Echinoparyphium lineage 3 were both able to detect Planorbella trivolvis, we found no evidence that either parasite chose their host based on echinostome infection status. Overall, this thesis offers novel insights into the diversity and ecology of this medically and ecologically important family of trematode parasites.

description: This paper examines the relationship between annual hours worked and rural residence for a sample of working-age (18-64 years) householders using 1993 Panel Study of Income Dynamics data. The basic question we address is whether and to what extent failure to account for rural residential choice biases the measured effect of rural residence on labor market outcomes. Results from a single equation model that assumes rural residence is exogenous finds no statistically significant relationship between annual hours worked and living in a rural area. By contrast, a simultaneous model that accounts for the possibility that rural residence is a choice indicates that rural people worked 307 hours more than urban people, all else being equal. A Smith-Blundell test for exogeneity of rural residence suggests that rural location should be treated as a choice variable. Study findings highlight the importance of testing, and if necessary, correcting for endogeneity of rural residence if we are to obtain accurate measures of the effect of living in a rural location on individual behavior and well-being.
Quickest Bayesian and non-Bayesian detection of false data injection attack in remote state estimation

description: In this paper, quickest detection of false data injection attack on remote state estimation is considered. A set of $N$ sensors make noisy linear observations of a discrete-time linear process with Gaussian noise, and report the observations to a remote estimator. The challenge is the presence of a few potentially malicious sensors which can start strategically manipulating their observations at a random time in order to skew the estimates. The quickest attack detection problem for a known {\em linear} attack scheme in the Bayesian setting with a Geometric prior on the attack initiation instant is posed as a constrained Markov decision process (MDP), in order to minimize the expected detection delay subject to a false alarm constraint, with the state involving the probability belief at the estimator that the system is under attack. State transition probabilities are derived in terms of system parameters, and the structure of the optimal policy is derived analytically. It turns out that the optimal policy amounts to checking whether the probability belief exceeds a threshold. Next, generalized CUSUM based attack detection algorithm is proposed for the non-Bayesian setting where the attacker chooses the attack initiation instant in a particularly adversarial manner. It turns out that computing the statistic for the generalised CUSUM test in this setting relies on the same techniques developed to compute the state transition probabilities of the MDP. Numerical results demonstrate significant performance gain under the proposed algorithms against competing algorithms.

description: We report large scale Monte Carlo simulations of the equilibrium discrete Laplacian roughening (dLr) model, originally introduced as the simplest one accommodating the hexatic phase in two-dimensional melting. The dLr model is also relevant to surface roughening in molecular beam epitaxy (MBE). Our data suggest a single phase transition, possibly of the Kosterlitz-Thouless type, between a flat low-temperature phase and a rough, tensionless, high-temperature phase. Thus, earlier conclusions on the order of the phase transition and on the existence of a hexatic phase are seen as due to finite size effects, the phase diagram of the dLr model being similar to that of a continuum analog previously formulated in the context of surface growth by MBE.

description: The development of agricultural biotechnology offers the opportunity to increase crop production, lowers farming costs, improves food quality and could reduce costs to consumers. For the food importing economies, the import quantities as well as prices will be affected through world market as the production technology of GM crops is adopted by the exporting countries. Many sectors will be affected by the use of these crops through vertical (or backward) and horizontal (or forward) linkages. The purpose of this paper is to develop an economy-wide quantitative assessment of the economic impacts of the introduction of GM products with and without labeling. The modeling framework used in this analysis is TAIGEM (Taiwan General Equilibrium Model), a multi-sectoral computable general equilibrium (CGE) model of the Taiwan¡¦s economy which is derived from ORANI model (Dixon, Parmenter, Sutton and Vincent, 1982). TAIGEM is amended by splitting corn and soybeans into GM and non-GM varieties. It also endogenizes the decision of producers and consumers to use GM vs. non-GM corn and soybeans in their intermediate uses and consumption, respectively. We also consider the consumers¡¦ acceptance of GM food so that the mandatory labeling policy can be examined. Our simulation results indicate that the most extreme import ban on GM crops would be very costly in terms of total production values, ranging from NT$ 40 to 90 billions per year.

description: Scaling laws of dust, HI gas and metal mass with stellar mass, specific star formation rate and metallicity are crucial to our understanding of the buildup of galaxies through their enrichment with metals and dust. In this work, we analyse how the dust and metal content varies with specific gas mass ($M_{\text{HI}}$/$M_{\star}$) across a diverse sample of 423 nearby galaxies. The observed trends are interpreted with a set of Dust and Element evolUtion modelS (DEUS) - incluidng stellar dust production, grain growth, and dust destruction - within a Bayesian framework to enable a rigorous search of the multi-dimensional parameter space. We find that these scaling laws for galaxies with $-1.0\lesssim \log M_{\text{HI}}$/$M_{\star}\lesssim0$ can be reproduced using closed-box models with high fractions (37-89$\%$) of supernova dust surviving a reverse shock, relatively low grain growth efficiencies ($ε$=30-40), and long dus lifetimes (1-2\,Gyr). The models have present-day dust masses with similar contributions from stellar sources (50-80\,$\%$) and grain growth (20-50\,$\%$). Over the entire lifetime of these galaxies, the contribution from stardust ($>$90\,$\%$) outweighs the fraction of dust grown in the interstellar medium ($

description: Surface brightness-colour relations (SBCRs) are used to derive the stellar angular diameters from photometric observations. They have various astrophysical applications, such as the distance determination of eclipsing binaries or the determination of exoplanet parameters. However, strong discrepancies between the SBCRs still exist in the literature, in particular for early and late-type stars. We aim to calibrate new SBCRs as a function of the spectral type and the luminosity class of the stars. Our goal is also to apply homogeneous criteria to the selection of the reference stars and in view of compiling an exhaustive and up-to-date list of interferometric late-type targets. We implemented criteria to select measurements in the JMMC Measured Diameters Catalog (JMDC). We then applied additional criteria on the photometric measurements used to build the SBCRs, together with stellar characteristics diagnostics. We built SBCRs for F5/K7-II/III, F5/K7-IV/V, M-II/III and M-V stars, with respective RMS of $σ_{F_{V}} = 0.0022$ mag, $σ_{F_{V}} = 0.0044$ mag, $σ_{F_{V}} = 0.0046$ mag, and $σ_{F_{V}} = 0.0038$ mag. This results in a precision on the angular diameter of 1.0\%, 2.0\%, 2.1\%, and 1.7\%, respectively. These relations cover a large $V-K$ colour range of magnitude, from 1 to 7.5. Our work demonstrates that SBCRs are significantly dependent on the spectral type and the luminosity class of the star. Through a new set of interferometric measurements, we demonstrate the critical importance of the selection criteria proposed for the calibration of SBCR. Finally, using the Gaia photometry for our samples, we obtained (G-K) SBCRs with a precision on the angular diameter between 1.1\% and 2.4\%.

description: This study assesses the impact of adopting international food safety standards and regional harmonization of standards on global trade patterns of cereals, dried fruits and nuts. The paper develops econometric models to estimate the effect of aflatoxin standards in 15 importing countries on the export from 31 (21 developing ) countries in the world. Results are combined to predict how the direction of trade is altered by food safety regulations under alternative scenarios. Adopting international food safety standards recommended by Codex is found to increase the trade among these countries by 5.3 percent. At the level where the increase and decrease in trade flow are break-even, EU countries increase both imports and exports whereas the decrease in trade flow among developing countries outweighs the improved access of these countries to the EU market.
Compressed Existence and Pointer-Based Self
Creators: name: Yoan, H
Publisher: name: Zenodo
Year: 2025
Subjects: consciousness, ontology, time, simulation theory, selfhood, information theory, pointer theory, cognitive science

description: This paper proposes a new ontological framework where existence is cognitively “decompressed,” and the self is defined not as stored memory but as a pointer referencing it. Time is reconceptualized as a function of cognition, and death is seen as the dereferencing of the self-pointer. This theory intersects with philosophy of mind, simulation theory, and relativity-based temporality.
Origin of Mass. Mass and Mass-Energy Equation from Classical-Mechanics Solution
Creators: name: Zheng-Johansson, J. X.

description: We establish the classical wave equation for a particle formed of a massless oscillatory elementary charge generally also traveling, and the resulting electromagnetic waves, of a generally Doppler-effected angular frequency $\w$, in the vacuum in three dimensions. We obtain from the solutions the total energy of the particle wave to be $\eng=\hbarc\w$, $2π\hbarc$ being a function expressed in wave-medium parameters and identifiable as the Planck constant. In respect to the train of the waves as a whole traveling at the finite velocity of light $c$, $\eng=mc^2$ represents thereby the translational kinetic energy of the wavetrain, $m=\hbarc\w/c^2$ being its inertial mass and thereby the inertial mass of the particle. Based on the solutions we also write down a set of semi-empirical equations for the particle's de Broglie wave parameters. From the standpoint of overall modern experimental indications we comment on the origin of mass implied by the solution.

description: In this study, we establish a network structure of the Korean stock market, one of the emerging markets, with its minimum spanning tree through the correlation matrix. Base on this analysis, it is found that the Korean stock market doesn't form the clusters of the business sectors or of the industry categories. When the MSCI (Morgan Stanley Capital International Inc.) index is exploited, we found that the clusters of the Korean stock market is formed. This finding implicates that the Korean market, in this context, is characteristically different form the mature markets.

The record keeping practices of women’s organizations : a case study of three organizations in Vancouver, British Columbia
Creators: name: Buhlmann, Jana Patricia
Publisher: name: University of British Columbia
Year: 2009

description: Examination of the context of record creation, maintenance, and use is a valuable tool which allows the archivist to build a body of knowledge regarding archival records and their creators. Such knowledge enables the archivist to make informed decisions in all realms of archival practice. This discussion focuses upon the women's organization, undertaking a case study of three organizations in Vancouver, British Columbia in order to provide information about their record keeping practices. The case study employs open-ended focus interviews, observation, and document analysis, where provided. Participants are selected based upon their involvement in the creation, maintenance, and use of records in their respective organizations. They are asked to provide information as to the administrative history of the organization and to describe the processes by which they receive, create, use, organize, maintain, and destroy records. Participants are also asked to characterize their organization and its record keeping practices as they relate to the concept of a women's organization. A framework for analysis is established, which allows for further characterization of each women's organization. This framework addresses the voluntary nature of most women's organizations, as well as their unique processes and forms. Three models are presented which allow for further characterization of the history, structure, and practices of each organization. The distinctive internal processes, forms, and record keeping practices of the Women's International League for Peace and Freedom, the Western Businesswomen's Association, and the West Coast Women's Legal Education and Action Fund are presented. The thesis concludes by providing recommendations regarding further explorations of record creation, maintenance, and use and their value for the archival profession.
Photo-assisted shot noise in the fractional quantum Hall regime

description: The effect of an ac perturbation on the shot noise of a fractional quantum Hall fluid is studied at finite temperature. For a normal metal, it is known that the zero-frequency noise derivative exhibits steps as a function of bias voltage. In contrast, at Laughlin fractions, the backscattering noise exhibits evenly spaced singularities, which are reminiscent of tunneling density-of-states singularities for quasiparticles. The spacing is determined by the quasiparticle charge $νe$ and the ratio of the dc bias with respect to the drive frequency. Photo-assisted transport can thus be considered as a probe for effective charges of the quantum Hall effect.

description: The structure of Chinese food demand is examined using a non-homothetic translog indirect utility function. This analysis uses household level survey data for 3 urban Chinese provinces over the 1995-1997 period. We improve upon previous studies by incorporating theoretically consistent equivalence scales to account for differences in household size and composition. These scales allow us to quantify the impact of alternative types of household members on food expenditures. Similar to previous research we find little evidence of purchase economies with the addition of members although, depending on age, we find statistically significant differences in equivalence values across household member age grouping.

description: The uncharted territory of the high-redshift ($z\gtrsim3$) Universe holds the key to understand the evolution of quasars. In an attempt to identify the most extreme members of the quasar population, i.e., blazars, we have carried out a multi-wavelength study of a large sample of radio-loud quasars beyond $z=3$. Our sample consists of 9 $γ$-ray detected blazars and 133 candidate blazars selected based on the flatness of their soft X-ray spectra (0.3$-$10 keV photon index $\leq1.75$), including 15 with NuSTAR observations. The application of the likelihood profile stacking technique reveals that the high-redshift blazars are faint $γ$-ray emitters with steep spectra. The high-redshift blazars host massive black holes ($\langle \log~M_{\rm BH,~M{\odot}} \rangle>9$) and luminous accretion disks ($\langle L_{\rm disk} \rangle>10^{46}$ erg s$^{-1}$). Their broadband spectral energy distributions are found to be dominated by high-energy radiation indicating their jets to be among the most luminous ones. Focusing on the sources exhibiting resolved X-ray jets (as observed with the Chandra satellite), we find the bulk Lorentz factor to be larger with respect to other $z>3$ blazars, indicating faster moving jets. We conclude that the presented list of the high-redshift blazars may act as a reservoir for follow-up observations, e.g., with NuSTAR, to understand the evolution of relativistic jets at the dawn of the Universe.

description: One dimensional SU($n$) chains with the same irreducible representation $\mathcal{R}$ at each site are considered. We determine which $\mathcal{R}$ admit low-energy mappings to a $\text{SU}(n)/[\text{U}(1)]^{n-1}$ flag manifold sigma model, and calculate the topological angles for such theories. Generically, these models will have fields with both linear and quadratic dispersion relations; for each $\mathcal{R}$, we determine how many fields of each dispersion type there are. Finally, for purely linearly-dispersing theories, we list the irreducible representations that also possess a $\mathbb{Z}_n$ symmetry that acts transitively on the $\text{SU}(n)/[\text{U}(1)]^{n-1}$ fields. Such SU($n$) chains have an 't Hooft anomaly in certain cases, allowing for a generalization of Haldane's conjecture to these novel representations. In particular, for even $n$ and for representations whose Young tableaux have two rows, of lengths $p_1$ and $p_2$ satisfying $p_1\not=p_2$, we predict a gapless ground state when $p_1+p_2$ is coprime with $n$. Otherwise, we predict a gapped ground state that necessarily has spontaneously broken symmetry if $p_1+p_2$ is not a multiple of $n$.
