description: We reconsider an alternative theory of the QED with the photon as a massless vector Nambu-Goldstone boson and show that the underlying spontaneous Lorentz violation caused by the vector field vacuum expectation value, while being superficial in gauge invariant theory, becomes physically significant in the QED with a tiny gauge non-invariance. This leads, through special dispersion relations appearing for charged fermions, to a new class of phenomena which could be of distinctive observational interest in particle physics and astrophysics. They include a significant change in the GZK cutoff for UHE cosmic-ray nucleons, stability of high-energy pions and W bosons, modification of nucleon beta decays, and some others.

description: The basic properties of oscillons -- localized, long-lived, time-dependent scalar field configurations -- are briefly reviewed, including recent results demonstrating how their existence depends on the dimensionality of spacetime. Their role on the dynamics of phase transitions is discussed, and it is shown that oscillons may greatly accelerate the decay of metastable vacuum states. This mechanism for vacuum decay -- resonant nucleation -- is then applied to cosmological inflation. A new inflationary model is proposed which terminates with fast bubble nucleation.

description: The multiwavelength observation of the nearby radio galaxy M87 provides a unique opportunity to study in detail processes occurring in Active Galactic Nuclei from radio waves to TeV gamma-rays. Here we report the detection of gamma-ray emission above 250 GeV from M87 in spring 2007 with the VERITAS atmospheric Cherenkov telescope array and discuss its correlation with the X-ray emission. The gamma-ray emission is measured to be point-like with an intrinsic source radius less than 4.5 arcmin. The differential energy spectrum is fitted well by a power-law function: dPhi/dE=(7.4+-1.3_{stat}+-1.5_{sys})(E/TeV)^{-2.31+-0.17_{stat}+-0.2_{sys}} 10^{-9}m^{-2}s^{-1}TeV^{-1}. We show strong evidence for a year-scale correlation between the gamma-ray flux reported by TeV experiments and the X-ray emission measured by the ASM/RXTE observatory, and discuss the possible short-time-scale variability. These results imply that the gamma-ray emission from M87 is more likely associated with the core of the galaxy than with other bright X-ray features in the jet.

description: More than 150 years after their invention by Hamilton, quaternions are now widely used in the aerospace and computer animation industries to track the paths of moving objects undergoing three-axis rotations. It is shown here that they provide a natural way of selecting an appropriate ortho-normal frame -- designated the quaternion-frame -- for a particle in a Lagrangian flow, and of obtaining the equations for its dynamics. How these ideas can be applied to the three-dimensional Euler fluid equations is then considered. This work has a bearing on the issue of whether the Euler equations develop a singularity in a finite time. Some of the literature on this topic is reviewed, which includes both the Beale-Kato-Majda theorem and associated work on the direction of vorticity by both Constantin, Fefferman & Majda and Deng, Hou and Yu. It is then shown how the quaternion formulation provides a further direction of vorticity result using the Hessian of the pressure.

We studied the electric potential distribution in the discharge gap in kind formed double layer. The local plasma heating by electron beam, formed in the double layer, leads to generation of peak radiation pulses and as a result to an increase in the radiation power.

description: Urbanization alters watershed hydrology and has increased nutrient pollution, leading to eutrophication and hypoxia in downstream coastal ecosystems.  In order to manage increased nutrient exports and loss of biogeochemical functions in urban streams and rivers it is important to better understand how management of both point and diffuse sources affects carbon and nutrients under various flow conditions.  The objective of this research was to investigate the impacts of urban development on sources, transformations, and fluxes of carbon (C) and nutrients along urban headwater streams and a large coastal estuary.  Chapter 1 covers the impact of headwater stream burial on nitrate uptake and stream metabolism.  Chapter 2 focuses on the impact of age and extent of urban infrastructure and watershed management on hydrologic variability and pulsing of C and nutrient sources and fluxes.  Chapter 3 examines the capacity of a large river-estuary system to transform and remove inputs of nitrogen (N) and C from a major metropolitan area and the world's largest advanced wastewater treatment plant.  Results from Chapter 1 indicate that burial of headwater streams significantly reduces nitrate uptake, gross primary productivity, and ecosystem respiration, compared to non-buried streams, by factors of 9.6, 11, and 5, respectively.  It was also estimated that at the watershed scale, stream burial decreases N uptake by 39 ? 5% and C production by 105 ? 103%.  Results from Chapter 2 indicate that urbanized streams with higher percent impervious surface cover and older infrastructure have greater inputs of N, C, and phosphorus (P) from leaky sanitary sewers and flashier hydrology, resulting in higher concentrations and more variable and pulsed exports of C, N, and P.  Results from Chapter 3 indicate that large river-estuary systems have the potential to transform and remove N loads from point-source wastewater treatment plant inputs over relatively short spatial scales.  There were seasonal patterns in N removal in the Potomac River Estuary, with greater denitrification and uptake rates in the summer and fall, accompanied by lower net exports, but during the spring when flows were highest, exports were also highest.  Overall, the research in this dissertation indicates that urbanization reduces nutrient retention through stream burial and increases the amount and variability of C and nutrient exports in headwater streams, while river-estuarine systems have a large capacity to assimilate nutrient inputs from major point sources.

description: The RApid Temporal Survey (RATS) is a survey to detect objects whose optical intensity varies on timescales of less than ~70 min. In our pilot dataset taken with the INT and the Wide Field Camera in Nov 2003 we discovered nearly 50 new variable objects. Many of these varied on timescales much longer than 1 hr. However, only 4 objects showed a modulation on a timescale of 1 hour or less. This paper presents followup optical photometry and spectroscopy of these 4 objects. We find that RAT J0455+1305 is a pulsating (on a period of 374 sec) subdwarf B (sdB) star of the EC 14026 type. We have modelled its spectrum and determine Teff = 29,200+/- 1900K and log g = 5.2+/-0.3 which locates it on the cool edge of the EC 14026 instability strip. It has a modulation amplitude which is one of the highest of any known EC 14026 star. Based on their spectra, photometric variability and their infra-red colours, we find that RAT J0449+1756, RAT J0455+1254 and RAT J0807+1510 are likely to be SX Phe stars - dwarf Delta Sct stars. Our results show that our observing strategy is a good method for finding rare pulsating stars.

Transport, destruction and growth of pebbles in the gas envelope of a protoplanet

description: We analyse the size evolution of pebbles accreted into the gaseous envelope of a protoplanet growing in a protoplanetary disc, taking into account collisions driven by the relative sedimentation speed as well as the convective gas motion. Using a simple estimate of the convective gas speed based on the pebble accretion luminosity, we find that the speed of the convective gas is higher than the sedimentation speed for all particles smaller than 1 mm. This implies that both pebbles and pebble fragments are strongly affected by the convective gas motion and will be transported by large-scale convection cells both towards and away from the protoplanet's surface. We present a simple scheme for evolving the characteristic size of the pebbles, taking into account the effects of erosion, mass transfer and fragmentation. Including the downwards motion of convective cells for the transport of pebbles with an initial radius of 1 millimeter, we find pebble sizes between 100 microns and 1 millimeter near the surface of the protoplanet. These sizes are generally amenable to accretion at the base of the convection flow. Small protoplanets far from the star (>30 AU) nevertheless erode their pebbles to sizes below 10 microns; future hydrodynamical simulations will be needed to determine whether such small fragments can detach from the convection flow and become accreted by the protoplanet.

Playing with power : a strengths-based approach to local economic development in the Philippines

description: This thesis explores the contested nature of power relations in community development. It draws on an ethnographic account of the Jagna Community Partnering Project (JCPP) implemented on the island province of Bohol in the Philippines to stimulate local economic development. The project applied post-development principles using participatory, strengths-based and action research approaches that built on informal economic practices to establish community enterprises. Through this process, the JCPP disrupted the hegemony of local development discourses, catalysing profound changes in the lives of project participants who moved from perceiving themselves as passive and dependent recipients of development to self-reliant and active decision-makers. This thesis examines the varied, complex and sometimes hidden ways participants exercised the power available to them in both formal and informal arenas to create alternative development pathways aligned with their own interests and agendas. Drawing attention to the multiple and often contradictory ways in which different development actors are simultaneously enabled and constrained in any given moment, this place-based analysis offers a nuanced conceptualisation of power as more dynamic than general accounts of Philippine politics often suggest. Findings raise questions about the assumption commonly held by policy makers that capitalist economic development will inevitably expand the power and influence of marginalised groups and show how informal economic practices can provide a platform for individual and collective action.

The BES f_0(1810): a new glueball candidate

description: We analyze the f_0(1810) state recently observed by the BES collaboration via radiative J/ψdecay to a resonant ϕωspectrum and confront it with DM2 data and glueball theory. The DM2 group only measured ωωdecays and reported a pseudoscalar but no scalar resonance in this mass region. A rescattering mechanism from the open flavored KKbar decay channel is considered to explain why the resonance is only seen in the flavor asymmetric ωϕbranch along with a discussion of positive C parity charmonia decays to strengthen the case for preferred open flavor glueball decays. We also calculate the total glueball decay width to be roughly 100 MeV, in agreement with the narrow, newly found f_0, and smaller than the expected estimate of 200-400 MeV. We conclude that this discovered scalar hadron is a solid glueball candidate and deserves further experimental investigation, especially in the K-Kbar channel. Finally we comment on other, but less likely, possible assignments for this state.
description: 11 pages, 4 figures. Major substantive additions, including an ab-initio, QCD-based computation of the glueball inclusive decay width, evaluation of final state effects, and enhanced discussion of several alternative possibilities. Our conclusions are unchanged: the BES f_0(1810) is a promising glueball candidate

description: Multivariate analysis has undergone radical changes in the recent past with the advent of the so-called ultra high-dimensional data sets. Standard procedures cannot be applied for analysis of such data sets as they are all developed based on the assumption that the sample size is larger than the dimension of the data. Two different families of tests have been proposed so far for mean vector testing in high-dimensional case, but they work only when the observations are assumed to be independently and identically distributed. We propose a new testing procedure when the observations are dependent. Asymptotic normality of the proposed test statistic is derived under the assumption that the data is a realization of a M-dependent strictly stationary process. The proposed test is also extended to the two sample case.  Another aspect of multivariate analysis is testing independence of the variates. Likelihood ratio based tests for testing independence of variates assume independence amongst the observations. An extension of this problem to the time series setting is considered, with emphasis on testing the equality of correlation matrices at lag zero. A Wald-type test statistic is proposed for testing equality of correlation matrices between two dependent groups. Construction of a  MANOVA model for Resting State Networks(RSN) in brain imaging is discussed. The derived results are applied to validate the reproducibility and reliability of RSNs and compare several data pre-processing techniques. In multiple testing, estimation of the number of hypotheses accepted is of importance in certain problems. Measuring the proportion of accepted nulls gives a measure of sparsity of the noise. When the number of hypotheses to be tested is in millions, testing each hypothesis can be disregarded to estimate the proportion of accepted hypotheses. We study the properties of an empirical characteristic function based estimator for exponentially distributed signals. An iterative bias correction procedure is applied to improve the performance of the estimator. A non-parametric approach based on level set estimators is proposed.

description: This thesis investigates the nature of propositions. It examines three central theoretical roles of propositions: the role of semantic values, objects of attitudes, and contents of assertion. Chapter 2 and 3 study the nature of propositions in their role as compositional semantic values of sentences, while Chapter 4 and 5 explore their role as objects of attitudes and contents of assertion. Chapter 2 aims to show that semantic values of sentences cannot be identified with eternal propositions and gives a partial defense of Temporalism about semantic values. Chapter 3 defends a Fregean conception of semantic values. Chapter 4 presents a model of communication on which the truth of propositions in their roles as contents of attitudes and assertions is world, time and subject relative. Chapter 5 argues against Stalnaker's rival attempt of identifying both attitudinal and assertoric contents with eternal and impersonal propositions.

description: We present a systematic study of the Green functions of a one-dimensional gas of impenetrable anyons. We show that the one-particle density matrix is the determinant of a Toeplitz matrix whose large N asymptotic is given by the Fisher-Hartwig conjecture. We provide a careful numerical analysis of this determinant for general values of the anyonic parameter, showing in full details the crossover between bosons and fermions and the reorganization of the singularities of the momentum distribution function. We show that the one-particle density matrix satisfies a Painleve VI differential equation, that is then used to derive the small distance and large momentum expansions. We find that the first non-vanishing term in this expansion is always k^{-4}, that is proved to be true for all couplings in the Lieb-Liniger anyonic gas and that can be traced back to the presence of a delta function interaction in the Hamiltonian.

description: In this letter we show how the dispersion relation of surface plasmon polaritons (SPPs) propagating along a perfectly conducting wire can be tailored by corrugating its surface with a periodic array of radial grooves. In this way, highly localized SPPs can be sustained in the terahertz region of the electromagnetic spectrum. Importantly, the propagation characteristics of these spoof SPPs can be controlled by the surface geometry, opening the way to important applications such as energy concentration on cylindrical wires and superfocusing using conical structures.

description: Topological edge states are predicted to be responsible for the high efficient thermoelectric response of topological insulators, currently the best thermoelectric materials. However, to explain their figure of merit the coexistence of topological electrons, entropy and phonons can not be considered independently. In a background that puts together electrodynamics and topology, through an expression for the topological intrinsic field, we treat relativistic phonons within the topological surface showing their ability to modulate the Berry curvature of the bands and then playing a fundamental role in the thermoelectric effect. Finally, we show how the topological insulators under such relativistic thermal excitations keep time reversal symmetry allowing the observation of high figures of merit at high temperatures. The emergence of this new intrinsic topological field and other constraints are suitable to have experimental consequences opening new possibilities of improving the efficiency of this topological effect for their based technology.

description: Urban ecosystems are constantly evolving, and they are expected to change in both space and time with active management or degradation.   An urban watershed continuum (UWC) framework recognizes a continuum of engineered and natural hydrologic flowpaths that expand hydrologic networks in new ways that help us to use hydrologic connectivity to study and characterize downstream fluxes and transformations of carbon, contaminants, energy, and nutrients across four space and time dimensions.  Given current tendencies to transition from sanitary to sustainable cities, an UWC helps researchers and managers to acknowledge the evolving relationship between civil infrastructure and ecosystem function.      Leaf litter inputs are an integral part of the trophic structure of many stream ecosystems and litter breakdown is a key ecosystem function in forest and stream ecosystems.  Urban litter inputs are driven by civil drainage infrastructure rather than riparian sources.  Litter breakdown processes determine how much of these inputs are available, and in what form, for habitat and food resources both for local and downstream ecosystems.  These were measured in-situ for American Sycamore and London Planetree leaves in a forest and a suburban stream.  Leaf breakdown rates were faster in the more urbanized catchment stream, and for some of the more urbanized landscape sources.        The dense drainage networks of urban catchments facilitate organic matter transport, creating a gutter subsidy to streams that likely dwarf natural riparian input.  Storm and dry weather DOC, and FPOM samples from streams of the BES LTER urban stream network revealed temporally dynamic systems greatly influenced by impervious cover, with high OM fluxes and concentrations.  DOC and FPOM patterns and elevated post storm flow concentrations and fluxes suggest that the engineered subsurface drainage networks facilitate transport with both surface and groundwater playing key roles.  These create an urban stream continuum whereby upstream zero order stream functions are shifted up-gradient, into the landscape, making urban drainage an important part of an integrated ecohydrologic system.

description: Measurements of the nonlinear flux-flow resistivity $ρ$ and the critical vortex velocity $\rm v^*_ϕ$ at high voltage bias close to the instability regime predicted by Larkin and Ovchinnikov \cite{LO} are reported along the node and antinode directions of the d-wave order parameter in the \textit{a-b} plane of epitaxial $YBa_2Cu_3O_{7-δ}$ films. In this pinning-free regime, $ρ$ and $\rm v^*_ϕ$ are found to be anisotropic with values in the node direction larger on average by 10% than in the antinode direction. The anisotropy of $ρ$ is almost independent of temperature and field. We attribute the observed results to the anisotropic quasiparticle distribution on the Fermi surface of $YBa_2Cu_3O_{7-δ}$.

description: Ultra-hot Jupiters (UHJs) are highly irradiated giant exoplanets with extremely high day-side temperatures, which lead to thermal dissociation of most of the molecular species. It is expected that the neutral hydrogen atom is one of the main species in the upper atmospheres of ultra-hot Jupiters. Neutral hydrogen has been detected in several UHJs by observing its Balmer line absorption. Here, we report four transit observations of the ultra-hot Jupiter WASP-33b, performed with the CARMENES and HARPS-North spectrographs, and the detection of the H$α$, H$β$, and H$γ$ lines in the planetary transmission spectrum. The combined H$α$ transmission spectrum of the four transits has an absorption depth of 0.99$\pm$0.05 %, which corresponds to an effective radius of 1.31$\pm$0.01 Rp . The strong H$α$ absorption indicates that the line probes the high-altitude thermosphere. We further fitted the three Balmer lines using the PAWN model, assuming that the atmosphere is hydrodynamic and in LTE. We retrieved a thermosphere temperature $12200^{+1300}_{-1000}$ K and a mass-loss rate ${\rm \dot{M}}=10^{11.8^{+0.6}_{-0.5}}$ g/s. The retrieved large mass-loss rate is compatible with the "Balmer-driven" atmospheric escape scenario, in which the stellar Balmer continua radiation in the near-ultraviolet is substantially absorbed by the excited hydrogen atoms in the planetary thermosphere.

description: We study the collective interaction of excitons in closely spaced artificial molecules and arrays of nearly identical quantum dots with the electromagnetic modes. We discuss how collective fluorescence builds up in the presence of a small mismatch of the transition energy. We show that a superradiant state of a single exciton in a molecule of two dots with realistic energy mismatch undergoes a two-rate decay. We analyze also the stability of subdecoherent states for non-identical systems.

Year: 2009

description: The Washington Climate Change Impacts Assessment is the most comprehensive assessment of climate change impacts on Washington State completed to date. The assessment, funded by the Washington State Legislature through House Bill 1303, involved developing updated climate change scenarios for Washington State and using these scenarios to assess the impacts of climate change to the following sectors: agriculture, coasts, energy, forests, human health, urban stormwater infrastructure, salmon, and hydrology and water resources. Adaptation in each of these sectors was also discussed. The Executive Summary highlights major conclusions from the Washington Assessment, which was conducted by the Climate Impacts Group (CIG) at the University of Washington in partnership with Washington State University and Pacific Northwest National Laboratory.

description: Our research aims to study the conformations of complex carbohydrates and understand the degree of motion taking place within a timeframe of few milliseconds or less. This dissertation describes development and application of Nuclear Magnetic Resonance based methods using Residual Dipolar Coupling (RDC) measurement of weakly aligned molecules in liquid crystal media. We present a procedure that uses multivariate statistical techniques applied to multiple sets of RDC data to accurately quantify conformational space occupied by the macromolecule. The hexasaccharide Lacto–N–difuco–hexose–I (LNDFH–I) comprising of a tetrasaccharide epitope region (α–L–Fuc(1→2)β–D–Gal(1→3)(α–L–Fuc(1→4))β–D–GlcNAc) and a lactose tail region (?–D–GlcNAc1→3?–D–Gal1→4–D–Glc) was used as a model for the study. A liquid crystal concentration of 5% n–octyl penta ethylene glycol was found to be optimal to weakly align the oligosaccharide and measure the RDCs. To estimate the alignment tensors, at least five RDC values were measured for each pyranoside ring of the hexasaccharide, using one bond carbon — proton (13C, 1H) and long range proton — proton (1H, 1H) coupling experiments. The candidate conformers for this calculation were generated using sophisticated molecular dynamics (MD) simulation. Alignment tensors were determined using three different methods from which the dipolar couplings were back calculated. Multiple linear regression was applied to the calculated RDCs in order to find the sub-set of conformers which best fit the experimental data. The dihedral angles of the selected conformers were analyzed to understand the conformation. Results suggest relatively rigid conformation of the tetrasaccharide epitope of LNDFH–I. The average degree of motion for each glycosidic linkage within the tetrasaccharide was around ±7°. Three distinct families of conformers were observed for the β–D–GlcNAc1→3β–D–Gal linkage indicating flexibility. Large excursion of the dihedral angle was also observed for the lactose linkage at the reducing terminal. These results were validated using conformers generated from Monte Carlo simulation. The methodology was applied to the synthesized disaccharide (α–L–Col(1→2)β–D–Gal) and tetrasaccharide (α–L–Col(1→2)β–D–Gal(PO4−)(1→3)(α–L–Col(1→4))β–D–GlcNAc) components of the Vibrio cholerae O139 capsular polysaccharide. The results aided in further refinement of the conformational features of the tetrasaccharide as compared to previous studies. The disaccharide showed considerable flexibility with conformers in three distinct regions.
Leveraging Peer Review in Visualization Education: A Proposal for a New Model

description: In visualization education, both science and humanities, the literature is often divided into two parts: the design aspect and the analysis of the visualization. However, we find limited discussion on how to motivate and engage visualization students in the classroom. In the field of Writing Studies, researchers develop tools and frameworks for student peer review of writing. Based on the literature review from the field of Writing Studies, this paper proposes a new framework to implement visualization peer review in the classroom to engage today's students. This framework can be customized for incremental and double-blind review to inspire students and reinforce critical thinking about visualization.
THE IMPACT OF GLOBALIZATION ON MEDIA TRANSLATION BETWEEN UZBEK AND ENGLISH

Publisher: name: Zenodo
Year: 2024

description: This study explores the influence of globalization on media translation between Uzbek and English, focusing on how global media exchanges have shaped the translation of culture-specific references, idiomatic expressions, and technological advancements. The paper examines the challenges translators face in adapting media content for cross-cultural audiences while preserving the cultural and contextual integrity of the source language. Through a comparative analysis of linguistic borrowing, the tension between domestication and foreignization, and the role of technology in translation processes, the article highlights the critical importance of cultural literacy in media translation. This research provides insights into the growing demand for localized media content in an increasingly globalized world and underscores the evolving role of translators in navigating this dynamic field.

Digital Storytelling in ESL Instruction: Identity Negotiation through a Pedagogy of Multiliteracies

Subjects: a pedagogy of multiliteracies

multimodality

description: This qualitative descriptive exploratory study investigated how a pedagogy of multiliteracies can be introduced to the ESL curriculum using digital stories and explored the ways ESL learners negotiate their identities through the multimodality of this narrative genre. The study was based on the premise that in language education it is crucial to account for multimodality of discourses and bring students' diverse lifeworlds and experiences into the classroom thus extending an understanding of literacy to multimodal communication and inviting ESL learners to explore their multilayered and dynamic identities. The study elicited data through focused participant observations, content analysis of students' essays, weekly journals, and final semi-structured interviews, and through discourse analysis of the students' drafts of verbal narratives for digital stories, digital storyboards, and final digital storytelling projects. The findings revealed the presence of situated practice; overt instruction; critical framing; and, in a more limited way, transformed practice. While situated practice evolved with the students narrating about their families, life-changing events, and important cultural practices, overt instruction included explicit and systematic instruction and scaffolding that fostered students' multimodal meaning making through story writing and production. Combined with situated practice it resulted in critical framing when students reflected on their progress as language learners and analyzed multimodal cultural representations in their digital stories. Some nascent examples of transformed practice were evident when students suggested how the projects had influenced their overall approaches to learning and understanding of meaning making. Students negotiated their identities through the process and product of digital stories. The study revealed that none of the participants articulated as central an ESL student identity indicating that this social role was not particularly significant at the time of the digital story project. Instead, the students were storytellers and producers, mothers and sons, daughters and sisters, granddaughters and world travelers, friends, women and men, and people with unique cultural backgrounds and social experiences. And since the students were in constant communication with each other, personal stories became experiences that moved other students and influenced their understanding of cultural diversity. This collaborative process created a multicultural classroom community of practice conducive to the recognition of diverse identities and social roles.

description: We review recent analytic and numerical results concerning the confinement scenario in Coulomb gauge. We then consider a local, renormalizable, BRST-invariant action for QCD in Coulomb gauge that contains auxiliary bose and fermi ghost fields and sources. When the auxiliary fields are integrated out, one obtains the standard Coulomb gauge action with a cut-off at the Gribov horizon. We use the local formulation to calculate the leading correction to the Stefan-Boltzmann equation of state at high temperature due to the cut-off at the Gribov horizon. It is of order $g^6$, which is precisely the order at which the infrared divergence found by Lindé divergence first occurs. No such divergence arises in the present calculation because the propagator of would-be physical gluons is suppressed in the infrared due to the proximity of the Gribov horizon in infrared directions.
description: 14 pages. Version 3 contains a more physical and clearer derivation which explains the relation of the result to the cut-off at the Gribov horizon
