description: Building resilience into today's complex infrastructures is critical to the daily functioning of society and its ability to withstand and recover from natural disasters, epidemics, and cyber-threats. This study proposes quantitative measures that implement the definition of engineering resilience advanced by the National Academy of Sciences. The approach is applicable across physical, information, and social domains. It evaluates the critical functionality, defined as a performance function of time set by the stakeholders. Critical functionality is a source of valuable information, such as the integrated system resilience over a time interval, and its robustness. The paper demonstrates the formulation on two classes of models: 1) multi-level directed acyclic graphs, and 2) interdependent coupled networks. For both models synthetic case studies are used to explore trends. For the first class, the approach is also applied to the Linux operating system. Results indicate that desired resilience and robustness levels are achievable by trading off different design parameters, such as redundancy, node recovery time, and backup supply available. The nonlinear relationship between network parameters and resilience levels confirms the utility of the proposed approach, which is of benefit to analysts and designers of complex systems and networks.

A method that reveals the multi-level ultrametric tree hidden in p-spin glass like systems

description: In the study of disordered models like spin glasses the key object of interest is the rugged energy hypersurface defined in configuration space. The statistical mechanics calculation of the Gibbs-Boltzmann Partition Function gives the information necessary to understand the equilibrium behavior of the system as a function of the temperature but is not enough if we are interested in more general aspects of the hypersurface: it does not give us, for instance, the different degrees of ruggedness at different scales. In the context of the Replica Symmetry Breaking (RSB) approach we discuss here a rather simple extension that can provide a much more detailed picture. The attractiveness of the method relies in that it is conceptually transparent and the additional calculations are rather straightforward. We think that this approach reveals an ultrametric organisation with many levels in models like p-spin glasses when we include saddle points. In this first paper we present the detailed calculations for the spherical p-spin glass model where we discover that the corresponding decreasing Parisi function $q(x)$ codes this hidden ultrametric organisation.
title: Some problems related to plethysm
Creators: name: Brown, David
Publisher: name: University of Kent
Year: 2023

description: This thesis is concerned with plethysm. It investigates certain plethysm coefficients and also studies a diagram algebra whose representation theory is related to plethysm. We use techniques involving plethystic semistandard Young tableaux in order to provide information about near-maximal constituents of the plethysm sν ◦sµ when µ = (m),(12 ) or (2, 1). We study further the case where µ = (12 ) by the means of a recursive formula of Law and Okitani. We study the ramified partition algebra, proving some new results about its representation theory. We show that the ramified partition algebra is a cellular algebra and investigate its cell modules. We show that the cell modules of the ramified partition algebra form a stratifying system, and hence prove an analogue of the Hemmer-Nakano theorem for this algebra. We give partial results on the semisimplicity of the ramified partition algebra over C, making a conjecture for the general case. Finally, we study the restriction of the cell modules for the ramified partition algebra to the partition algebra, investigating two filtrations and making progress on the decomposition of such modules.

description: We investigated the absolute age of the Galactic globular cluster M71 (NGC 6838) by using optical ground-based images (u',g',r',i',z') collected with the MegaCam camera at the Canada-France-Hawaii-Telescope (CFHT). We performed a robust selection of field and cluster stars by applying a new method based on the 3D (r',u'-g',g'-r') Color-Color-Magnitude-Diagram. The comparison between the Color-Magnitude-Diagram of the candidate cluster stars and a new set of isochrones, at the locus of the Main Sequence Turn Off (MSTO), suggests an absolute age of 12+/-2 Gyr. The absolute age was also estimated using the difference in magnitude between the MSTO and the so-called main sequence knee, a well defined bending occurring in the lower main sequence. This feature was originally detected in the near-infrared (NIR) bands and explained as a consequence of an opacity mechanism (collisionally induced absorption of molecular hydrogen) in the atmosphere of cool low-mass stars (Bono et al. 2010). The same feature was also detected in the r',u'-g' and in the r',g'-r' CMD, thus supporting previous theoretical predictions by Borysow et al. (1997). The key advantage in using the Delta^(Knee)_(TO) as an age diagnostic is that it is independent of uncertainties affecting the distance, the reddening and the photometric zero-point. We found an absolute age of 12+/-1 Gyr that agrees, within the errors, with similar age estimates, but the uncertainty is on average a factor of two smaller. We also found that the Delta^(Knee)_(TO) is more sensitive to the metallicity than the MSTO, but the dependence becomes vanishing using the difference in color between the MSK and the MSTO.

description: Harvesting cultivated macrophages for tissue engineering purposes by enzymatic digestion of cell adhesion molecules can potentially result in unintended activation, altered function, or behavior of these cells. Thermo-responsive polymer is a promising tool that allows for gentle macrophage detachment without artificial activation prior to subculture within engineered tissue constructs. We therefore characterized different species of thermo-responsive polymers for their suitability as cell substrate and to mediate gentle macrophage detachment by temperature shift. Primary human monocyte- and THP-1-derived macrophages were cultured on thermo-responsive polymers and characterized for phagocytosis and cytokine secretion in response to lipopolysaccharide stimulation. We found that both cell types differentially respond in dependence of culture and stimulation on thermo-responsive polymers. In contrast to THP-1 macrophages, primary monocyte–derived macrophages showed no signs of impaired viability, artificial activation, or altered functionality due to culture on thermo-responsive polymers compared to conventional cell culture. Our study demonstrates that along with commercially available UpCell carriers, two other thermo-responsive polymers based on poly(vinyl methyl ether) blends are attractive candidates for differentiation and gentle detachment of primary monocyte–derived macrophages. In summary, we observed similar functionality and viability of primary monocyte–derived macrophages cultured on thermo-responsive polymers compared to standard cell culture surfaces. While this first generation of custom-made thermo-responsive polymers does not yet outperform standard culture approaches, our results are very promising and provide the basis for exploiting the unique advantages offered by custom-made thermo-responsive polymers to further improve macrophage culture and recovery in the future, including the covalent binding of signaling molecules and the reduction of centrifugation and washing steps. Optimizing these and other benefits of thermo-responsive polymers could greatly improve the culture of macrophages for tissue engineering applications.

description: Two-dimensional (2D) topological insulator (TI) have been recognized as a new class of quantum state of matter. They are distinguished from normal 2D insulators with their nontrivial band-structure topology identified by the $Z_2$ number as protected by time-reversal symmetry (TRS). 2D TIs have intriguing spin-velocity locked conducting edge states and insulating properties in the bulk. In the edge states, the electrons with opposite spins propagate in opposite directions and the backscattering is fully prohibited when the TRS is conserved. This leads to quantized dissipationless "two-lane highway" for charge and spin transportation and promises potential applications. Up to now, only very few 2D systems have been discovered to possess this property. The lack of suitable material obstructs the further study and application. Here, by using first-principles calculations, we propose that the functionalized MXene with oxygen, M$_2$CO$_2$ (M=W, Mo and Cr), are 2D TIs with the largest gap of 0.194 eV in W case. They are dynamically stable and natively antioxidant. Most importantly, they are very likely to be easily synthesized by recent developed selective chemical etching of transition-metal carbides (MAX phase). This will pave the way to tremendous applications of 2D TIs, such as "ideal" conducting wire, multifunctional spintronic device, and the realization of topological superconductivity and Majorana modes for quantum computing.

description: This study follows the possibility to tune the thermal stability of some CaCO3/polymer composites by crystal growth from supersaturated solutions controlled by polymer structure or by using nonstoichiometric polyelectrolyte complexes (NPECs). As the ratio between the organic and inorganic parts in the composites controls the Ca2+/polymer network crosslinking density, the CaCO3/polymer weight ratio was kept constant at 50/1, varying the initial concentration of the polyanions solutions (0.05 or 0.06 wt.%), the NPECs molar ratio , n+/n- (0.2 or 0.4), or the inorganic precursors concentration (0.25 or 0.3 M). Poly(2-acrylamido-2-methylpropanesulfonic acid-co-acrylic acid) (PSA) and chondroitin-4-sulfate (CSA) were used as polyanions. Some NPEC dispersions, prepared with the same polyanions and poly(allylamine hydrochloride) (PAH), were also used for calcium carbonate crystallization. The characteristics of the prepared composites were investigated by scanning electron microscopy (SEM), flow particle image analysis (FPIA), particles charge density (CD), zeta-potential (ZP). The thermal stability of the composite particles was investigated as compared to bare CaCO3 microparticles prepared at the same initial inorganic concentrations.

description: Polyhedral oligomeric silsesquioxane (POSS), bearing eight 3-chloroammoniumpropyl substituents, was studied as a potential nanocarrier in co-delivery systems with doxorubicin (DOX). The toxicity of doxorubicin and POSS:DOX complexes at four different molar ratios (1:1; 1:2, 1:4, 1:8) towards microvascular endothelial cells (HMEC-1), breast cancer cells (MCF-7), and human cervical cancer endothelial cells (HeLa) was determined. The rate of penetration of the components into the cells, their cellular localization and the hydrodynamic diameter of the complexes was also determined. A cytotoxicity profile of POSS:DOX complexes indicated that the POSS:DOX system at the molar ratio of 1:8 was more effective than free DOX. Confocal images showed that DOX co-delivery with POSS allowed for more effective penetration of doxorubicin through the cell membrane. Taking all the results into account, it can be claimed that the polyhedral oligomeric silsesquioxane (T8-POSS) is a promising, complex nanocarrier for doxorubicin delivery.
A microengineered collagen scaffold for generating a polarized crypt-villus architecture of human small intestinal epithelium
Creators: name: Wang, Yuli
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: The human small intestinal epithelium possesses a distinct crypt-villus architecture and tissue polarity in which proliferative cells reside inside crypts while differentiated cells are localized to the villi. Indirect evidence has shown that the processes of differentiation and migration are driven in part by biochemical gradients of factors that specify the polarity of these cellular compartments; however, direct evidence for gradient-driven patterning of this in vivo architecture has been hampered by limitations of the in vitro systems available. Enteroid cultures are a powerful in vitro system; nevertheless, these spheroidal structures fail to replicate the architecture and lineage compartmentalization found in vivo, and are not easily subjected to gradients of growth factors. In the current work, we report the development of a micropatterned collagen scaffold with suitable extracellular matrix and stiffness to generate an in vitro self-renewing human small intestinal epithelium that replicates key features of the in vivo small intestine: a crypt-villus architecture with appropriate cell-lineage compartmentalization and an open and accessible luminal surface. Chemical gradients applied to the crypt-villus axis promoted the creation of a stem/progenitor-cell zone and supported cell migration along the crypt-villus axis. This new approach combining microengineered scaffolds, biophysical cues and chemical gradients to control the intestinal epithelium ex vivo can serve as a physiologically relevant mimic of the human small intestinal epithelium, and is broadly applicable to model other tissues that rely on gradients for physiological function.

description: The main purpose of this project is to determine the effectiveness of external orthoses/ devices and management of shoulder subluxation. There is a gap in literature that still exists on whether external orthoses help with management of a shoulder subluxation post stroke. By conducting this review, we aim to investigate the existing evidence on orthoses and their role of reducing an already subluxed shoulder. Overall, this review could have an impact clinically on physiotherapy intervention when it comes to managing patients post stroke with a shoulder subluxation.

description: Massive black holes in active galaxies are immersed in huge concentrations of late type stars in the galactic bulges and also early type massive stars in the nuclear stellar clusters which are additionally surrounded by quasi-spherical several kpc scale halos containing from a few hundred up to several thousand globular clusters (GCs). It is expected that significant numbers of red giant stars, massive stars and also GCs can move through the jet expelled from the central engine of active galaxy. We consider collisions of stars from the galactic bulge, nuclear cluster and globular clusters with the jet plasma. As a result of such collisions, multiple shocks are expected to appear in the jet around these compact objects. Therefore, the plasma in the kpc scale jet can be significantly disturbed. We show that particles can be accelerated on these shocks up to the multi-TeV energies. TeV leptons emit synchrotron radiation, extending up to the X-ray energies, and also comptonize radiation produced in a stellar cluster and also the Microwave Background Radiation to TeV $γ$-ray energies. We show that such non-thermal radiation is likely to be detectable from the intermediate scale jets of the nearby active galaxies for reasonable number of stars and GCs immersed within the jet. As an example, we calculate the expected non-thermal emission in the X-ray and gamma-ray energies from the nearby radio galaxy Cen A from which a steady gamma-ray emission with the complex spectrum has been recently reported by the Fermi and the HESS Observatories.

A world both small and wide: the letter-bearer’s journey from Cicero to Jerome
Creators: name: Moffatt, Nicole
Publisher: name: Macquarie University
Year: 2023
Subjects: Other education not elsewhere classified

description: This thesis offers an examination of the roles and literary depictions of letter bearers and changing patterns of communication in the Roman world in the periods between Cicero and Jerome. It also explores the extent to which the letter bearers themselves played a part in these changing patterns of communication. The research begins with an examination of the bearers for the letters of the Ciceronian collections. The study proceeds to consider the role of bearers in the correspondence of Pliny, Trajan, Fronto, Augustine, Paulinus of Nola and Jerome. Each chapter challenges the long-held perception of the letter bearer as a mere functionary with a role that was immutable. What emerges from the analysis of numerous largely overlooked epistolary asides is that the correspondents’ relationship with their bearers was both complex and evolving and that the bearers were always viewed as the critical facilitators of their highly influential epistolary networks.

description: We present the barium surface abundance of 12 blue stragglers (BSs) and 18 main-sequence (MS) stars in the intermediate-age open cluster NGC 6819 (2.5 Gyr) based on spectra obtained from the Hydra Multi-object Spectrograph on the WIYN 3.5 m telescope. For the MS stars we find [Fe/H] = $+$0.05 $\pm$ 0.04 and [Ba/Fe] = $-$0.01 $\pm$ 0.10. The majority of the BS stars are consistent with these values. We identify five BSs with significant barium enhancement. These stars most likely formed through mass transfer from an asymptotic giant branch star that polluted the surface of the BS with the nucleosynthesis products generated during thermal pulsations. This conclusion aligns with the results from the substantial work done on the BSs in old open cluster NGC 188 that identifies mass transfer as the dominant mechanism for BS formation in that open cluster. However, four of the BSs with enhanced barium show no radial-velocity evidence for a companion. The one star that is in a binary is a double-lined system, meaning the companion is not a white dwarf and not the remnant of a prior AGB star. In this paper we attempt to develop a consistent scenario to explain the origin of these five BSs.

description: We examine by extensive computer simulations the self-diffusion of anisotropic star like particles in crowded two-dimensional solutions. We investigate the implications of the area coverage fraction $ϕ$ of the crowders and the crowder-crowder adhesion properties on the regime of transient anomalous diffusion. We systematically compute the mean squared displacement (MSD) of the particles, their time averaged MSD, as well as the effective diffusion coefficient. The diffusion appears ergodic in the limit of long traces, such that the time averaged MSD converges towards the ensemble averaged MSD and features a small residual amplitude spread of the time averaged MSD from individual trajectories. At intermediate time scales we quantify the anomalous diffusion in the system. Also, we show that the translational---but not rotational---diffusivity of the particles $D$ is a non-monotonic function of the attraction strength between them. Both diffusion coefficients decrease as $D(ϕ)\sim (1-ϕ/ϕ^*)^2$ with the area fraction $ϕ$ occupied by the crowders. Our results might be applicable to rationalising the experimental observations of non-Brownian diffusion for a number of standard macromolecular crowders used in vitro to mimic the cytoplasmic conditions of living cells.

description: Applying semi-classical Quantum Mechanics, the vacuum fluctuations within a star are determined, assuming a constant mass density and applying a monopole approximation. It is found that the density for the vacuum fluctuations does not only depend linearly on the mass density, as assumed in a former publication, where neutron stars up to 6 solar masses were obtained. This is used to propose a simple model on the dependence of the dark energy to the mass density, as a function of the radial distance r. It is shown that stars with up to 200 solar masses can, in principle, be obtained. Though, we use a simple model, it shows that in the presence of vacuum fluctuations stars with large masses can be stabilized and probably stars up to any mass can exist, which usually are identified as black holes.

description: We derive the exact Helmholtz free energy (HFE) of the standard and staggered one-dimensional Blume-Emery-Griffiths (BEG) model in the presence of an external longitudinal magnetic field. We discuss in detail the thermodynamic behavior of the ferromagnetic version of the model, which exhibits magnetic field-dependent plateaux in the $z$-component of its magnetization at low temperatures. We also study the behavior of its specific heat and entropy, both per site, at finite temperature. The degeneracy of the ground state, at $T=0$, along the lines that separate distinct phases in the phase diagram of the ferromagnetic BEG model is calculated, extending the study of the phase diagram of the spin-1 antiferromagnetic (AF) Ising model in[S.M. de Souza and M.T. Thomaz, J. of Mag. and Mag. Mat. {354} (2014) 205]. We explore the implications of the equality of phase diagrams, at $T=0$, of the ferromagnetic BEG model with $\frac{K}{|J|} = -2$ and of the spin-1 AF Ising model for $\frac{D}{|J|} > \frac{1}{2}$.

description: The data mainly adopts population census data to analyze the population spatial distribution pattern and population regional differentiation characteristics of Fujian Province. By calculating the population density of each province and city and using the theoretical calculation of cumulative population density based on the Lorenz curve, Fujian Province is divided into 10 levels according to the cumulative population density. The population quantity and geographical area included in each level are then counted. Additionally, the population spatial differentiation characteristics are analyzed from four dimensions: longitude, latitude, vertical, and mountain-sea. Based on the population spatial differentiation characteristics, a population division plan for Fujian Province is proposed. Furthermore, the population growth rates on both sides of the population division plan are analyzed using census data from 1990 to 2020.

description: By adding a neutrino mass term to the Standard Model, which is Lorentz and $SU(2)\times U(1)$ invariant but non-local to evade $CPT$ theorem, it is shown that non-locality within a distance scale of the Planck length, that may not be fatal to unitarity in generic effective theory, can generate the neutrino-antineutrino mass splitting of the order of observed neutrino mass differences, which is tested in oscillation experiments, and non-negligible baryon asymmetry depending on the estimate of sphaleron dynamics. The one-loop order induced electron-positron mass splitting in the Standard Model is shown to be finite and estimated at $\sim 10^{-20}$ eV, well below the experimental bound $< 10^{-2}$ eV. The induced $CPT$ violation in the $K$-meson in the Standard Model is expected to be even smaller and well below the experimental bound $|m_{K}-m_{\bar{K}}|<0.44\times 10^{-18}$ GeV.

description: Understanding and manipulating work fluctuations in microscale and nanoscale systems are of both fundamental and practical interest. For example, in considering the Jarzynski equality $\langle e^{-βW} \rangle=e^{-βΔF}$, a change in the fluctuations of $e^{-βW}$ may impact on how fast the statistical average of $e^{-βW}$ converges towards the theoretical value $e^{-βΔF}$, where $W$ is the work, $β$ is the inverse temperature, and $ΔF$ is free energy difference between two equilibrium states. Motivated by our previous study aiming at the suppression of work fluctuations, here we obtain a principle of minimal work fluctuations. In brief, adiabatic processes as treated in quantum and classical adiabatic theorems yield the minimal fluctuations in $e^{-βW}$. In the quantum domain, if a system initially prepared at thermal equilibrium is subject to a work protocol but isolated from a bath during the time evolution, then a quantum adiabatic process without energy level crossing (or an assisted adiabatic process reaching the same final states as in a conventional adiabatic process) yields the minimal fluctuations in $e^{-βW}$, where $W$ is the quantum work defined by two energy measurements in the beginning and at the end of the process. In the classical domain where the classical work protocol is realizable by an adiabatic process, then the classical adiabatic process also yields the minimal fluctuations in $e^{-βW}$. Numerical experiments based on a Landau-Zener process confirm our theory in the quantum domain, and our theory in the classical domain explains our previous numerical findings regarding the suppression of classical work fluctuations [G.~Y.~Xiao and J.~B.~Gong, Phys. Rev. E {\bf 90}, 052132 (2014)].

OBJECTIVE. In a nationally representative cohort, we sought to assess the geographic and social distribution of PA facilities and how disparity in access might underlie population-level PA and overweight patterns. DESIGN, SETTING, AND PARTICIPANTS. Residential locations of US adolescents in wave I (1994–1995) of the National Longitudinal Study of Adolescent Health (N = 20745) were geocoded, and a 8.05-km buffer around each residence was drawn (N = 42857 census-block groups [19% of US block groups]). PA facilities, measured by national databases and satellite data, were linked with Geographic Information Systems technology to each respondent. Logistic-regression analyses tested the relationship of PA-related facilities with block-group socioeconomic status (SES) (at the community level) and the subsequent association of facilities with overweight and PA (at the individual level), controlling for population density. MAIN OUTCOME MEASURES. Outcome measures were overweight (BMI ≥ 95th percentile of the Centers for Disease Control and Prevention/National Center for Health Statistics growth curves) and achievement of ≥5 bouts per week of moderate-vigorous PA. RESULTS. Higher-SES block groups had a significantly greater relative odds of having 1 or more facilities. Low-SES and high-minority block groups were less likely to have facilities. Relative to zero facilities per block group, an increasing number of facilities was associated with decreased overweight and increased relative odds of achieving ≥5 bouts per week of moderate-vigorous PA. CONCLUSIONS. Lower-SES and high-minority block groups had reduced access to facilities, which in turn was associated with decreased PA and increased overweight. Inequality in availability of PA facilities may contribute to ethnic and SES disparities in PA and overweight patterns.

description: Graph structure patterns are widely used to model different area data recently. How to detect anomalous graph information on these graph data has become a popular research problem. The objective of this research is centered on the particular issue that how to detect abnormal graphs within a graph set. The previous works have observed that abnormal graphs mainly show node-level and graph-level anomalies, but these methods equally treat two anomaly forms above in the evaluation of abnormal graphs, which is contrary to the fact that different types of abnormal graph data have different degrees in terms of node-level and graph-level anomalies. Furthermore, abnormal graphs that have subtle differences from normal graphs are easily escaped detection by the existing methods. Thus, we propose a multi-representations space separation based graph-level anomaly-aware detection framework in this paper. To consider the different importance of node-level and graph-level anomalies, we design an anomaly-aware module to learn the specific weight between them in the abnormal graph evaluation process. In addition, we learn strictly separate normal and abnormal graph representation spaces by four types of weighted graph representations against each other including anchor normal graphs, anchor abnormal graphs, training normal graphs, and training abnormal graphs. Based on the distance error between the graph representations of the test graph and both normal and abnormal graph representation spaces, we can accurately determine whether the test graph is anomalous. Our approach has been extensively evaluated against baseline methods using ten public graph datasets, and the results demonstrate its effectiveness.

Publisher: name: Aestimum
Year: 2011

description: The paper provides a survey of the rich number of theories and models developed by regional economics over the last fifty years. The paper moves from location theory, to regional growth and local development, up to the most recent local growth theories, giving emphasis to the role in which space is conceived in the different approaches, and showing how regional economics moves from “space” to “territory” when space is included as an economic resource and as an independent production factor, a generator of static and dynamic advantages for the firms situated within it.

Inter-winding Distributed Capacitance and Guitar Pickup Transient Response

description: Simple RLC circuit models of guitar pickups do not account for audible features that characterize the pickup. Psycho-acoustic experiments reveal that any acoustically accurate model has to reproduce the first 30 milli-seconds of the transient response with extreme precision. The proposed model is impractical for simple-minded model reduction or brute force numerical simulations yet, by focusing on modeling electromagnetic details and exposing a connection to spectral graph theory, a framework for finding the transient response to sufficient accuracy is exposed.

description: One of the essential conditions to implementation of market oriented appraisal methods is to identify a comparable properties sample that meets comparability criteria in terms of “similarity degree”, which means that properties features are to be close one to the other, and reliability of the real estate selling prices, which could be conditioned by fortuitous circumstances and present different “reliability degree”. This paper aims to define some measures to quantitatively assess properties’ comparability degree, and set up a procedure able to perfect adjustment grid methods, correcting possible anomalies and dissimilarities in the appraisal sample.

description: We have fabricated a high-quality monolayer WSe2 film on bilayer graphene by epitaxial growth, and revealed the electronic states by spin- and angle-resolved photoemission spectroscopy. We observed a direct energy gap at the Brillounin-zone corner in contrast to the indirect nature of gap in bulk WSe2, which is attributed to the lack of interlayer interaction and the breaking of space-inversion symmetry in monolayer film. A giant spin splitting of ~0.5 eV, which is the largest among known monolayer transition-metal dichalcogenides, is observed in the energy band around the zone corner. The present results suggest a high potential applicability of WSe2 to develop advanced devices based with the coupling of spin- and valley-degrees of freedom.

description: This issue of Writingplace Journal moves into the field, exploring the moment when reflection turns into action, and questions how knowledge produced via research is appraised and applied on the ground. In the articles, authors reflect upon their concrete experiences where insights regarding the city and its narratives have been made operational. Understanding the urban as a complex expression of social, historical, material, spatial and temporal relations between people and their built environment, we argue that this comprehension of places demands and envisions action, by which active and transformative processes take place in the real world. Fieldwork is in this sense both research and event, both investigative process and performative project.

Towards an African-American Genealogy of Market and Religion in Rap Music
Creators: name: Pyon, Kevin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: This essay provides a new reading of the intersections between religion and rap music in its genealogical consideration of how black laborers’ orientations to the market—from the antebellum slave market to the contemporary music industry—have informed their consequent commodifications of race and religion. The essay (1) traces the informal economy and sacred world of the slaves to the twinned births of the modern black prosperity gospel and hip-hop culture and (2) connects the religio-economic modalities of postbellum
peddling and celebrity preachers to contemporary black prosperity preachers and hip-hop moguls. Finally, this essay concludes that the commodified formulations of race and religion in rap music represent transformations of spiritual and market categories of “authenticity” and “freedom” which have structured and sometimes limited our understandings of distinct articulations of race, religion, and the market throughout African-American history

description: The study of Asian civilizations and their contributions to the field of Book History, although important, are scarce in Brazilian literature and academia. This work aimed to analyze the path of printing in Korea, from woodblocks to typography, in the 13th–15th centuries. As well as shed light on the contribution of the Korean peninsula, before its division between north and south, to the history of world printing technology. Through bibliographic research for works by Korean authors, sinologists, and experts in Korea, it was found that due to the geographical proximity to China, the country received since ancient times significant influences regarding literary production. Despite these influences, it can be said that Korea developed independently and adapted each innovation to its own culture. In addition to being the pioneers in the production of movable metal types, they developed the techniques and practices needed for this type of printing. Korea was successful in both woodcut and typography, reaching its apex in the production of the Tripitaka Koreana woodblocks and the casting of the kabinja type in the 13th and 15th centuries, respectively. With the encouragement of Buddhism and Confucian ideals, it can be seen that literary production was in constant development to meet the needs of the time.
Consistent gauge interaction involving dynamical coupling and anomalous current

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

description: We show a possible way to construct a consistent formalism where the effective electric charge can change with space and time without destroying the invariance. In the previous work [1][2] we took the gauge coupling to be of the form $g(ϕ)j_μ(A^μ +\partial^μB)$ where $B$ is an auxiliary field, $ ϕ$ is a scalar field and the current $j_μ$ is the Dirac current. This term produces a constraint $ (\partial_μϕ) j^μ=0 $ which can be related to M.I.T bag model by boundary condition. In this paper we show that when we use the term $ g(ϕ)j_μ(A^μ - \partial^μ(\frac{1}{\square}\partial_ρA^ρ)) $, instead of the auxiliary field $ B $, there is a possibility to produce a theory with dynamical coupling constant, which does not produce any constraint or confinement. The coupling $ j_μ^{A}(A^μ - \partial^μ(\frac{1}{\square}\partial_ρA^ρ)) $ where $ j_μ^{A} $ is an anomalous current also discussed.
