description: The processes associated with the design and construction of major highways can cause divisive controversies with negative outcomes. These controversies arise from the anticipated impacts of proposed alternative highway locations before actual construction; however, much less attention is paid to the effects, predicted and unanticipated, of new roads after ribbons are cut. Once construction decisions are made, the short time period during construction and shortly after the grand opening provides a unique "window of opportunity" for communities to take positive actions to reap the full benefits of the highway while reducing its negative effects (Figure 1). To those communities willing to adapt to their changing environment, action taken during this particular time period can effectively produce positive benefits. There is no uncertainty about some of the highway's direct effects, such as redistribution of traffic volumes; however, indirect impacts, such as economic development along highway interchanges will not be felt for some time and are therefore amenable to change. The North Carolina Division ofCommunity Assistance, in cooperation with local governments, other state agencies, and the private sector, has initiated a study of the newest portion of Interstate 40, a four-lane divided limited-access road running from Raleigh to Wilmington, North Carolina. The goals of the study are to identify the major impacts of the highway corridor, as constructed and opened; and to develop actions that governments and the private sector can take to reduce the highway's negative impacts and maximize its positive ones.

description: The termination in the white dwarf luminosity function is a standard diagnostic tool for measuring the total age of nearby stellar populations. In this paper, an algorithm is presented for inverting the full white dwarf luminosity function to obtain a maximum likelihood estimate of the time varying star formation rate of the host stellar population. Tests with synthetic data demonstrate that the algorithm converges over a wide class of underlying star formation rate forms. The algorithm successfully estimates the moving average star formation rate as a function of lookback time in the presence of realistic measurement noise, though suffers from degeneracies around discontinuities in the underlying star formation rate. The inversion results are most sensitive to the choice of white dwarf cooling models, with the models produced by different groups giving quite different results. The results are relatively insensitive to the progenitor metallicity, initial mass function, initial-final mass relation and ratio of H/He atmosphere white dwarfs. Application to two independent determinations of the Solar neighbourhood white dwarf luminosity function gives similar results. The star formation rate has a bimodal form, with broad peaks at 2-3 Gyr and 7-9 Gyr in the past, separated by a significant lull of magnitude 30-90% depending on choice of cooling models. The onset of star formation occurs around 8-10 Gyr ago. The total integrated star formation rate is ~0.014 stars/pc3 in the Solar neighbourhood, for stars more massive than 0.6M_{solar}.

Year: 2012
Subjects: subject: Information Theory (cs.IT)

description: Three-Receiver broadcast channels (BC) are of interest due to their information-theoretic differences with two-receiver one. In this paper, we derive achievable rate regions for two classes of 3-receiver BC with side information (SI), i.e. Multilevel BC (MBC) and 3-receiver less noisy BC, using a combination of superposition coding, Gelfand-Pinsker binning scheme and Nair-El Gamal indirect decoding. Our rate region for MBC subsumes Steinberg rate region for 2-receiver degraded BC with SI as its special case. We will also show that the obtained achievable rate regions in the first two cases are tight for several classes of non-deterministic, semi-deterministic, and deterministic 3-receiver BC when SI is available both at the transmitter and at the receivers. We also prove that as far as a receiver is deterministic in the three-receiver less noisy BC, the presence of side information at that receiver does not affect the capacity region. We have also provided the writing on dirty paper (WDP) property for 3-receiver BC is provided as an example. In the last section, we provide simple bounds on the capacity region of the Additive Exponential noise three-receiver broadcast channels with Additive Exponential interference (AEN-3BC-EI).

description: Titandioxid-Nanopartikel (TiO2 NP) haben mittlerweile ein breites Anwendungsspektrum und sind besonders wegen ihrer Fähigkeit zur Photokatalyse interessant für Industrie und Forschung. In dieser Arbeit wurde die Phototoxizität von TiO2 NP und das damit verbundene Potential für den pharmazeutischen Einsatz in der Krebstherapie untersucht. Es wurde zunächst das Aufnahmeverhalten von zwei Säugerzelllinien, A549 und NIH/3T3, mittels Durchflusszytometrie und Time Lapse Mikroskopie analysiert. Dabei wurde festgestellt, dass die NIH/3T3 Zellen die Nanopartikel sehr effizient aufnahmen, während bei den A549 Zellen vorwiegend Agglomerat-Bildung und äußere Anlagerung beobachtet werden konnte. Es wurden keinerlei zytotoxische Effekte bei den verwendeten TiO2 NP für die untersuchten Zelllinien beobachtet. Dies änderte sich jedoch bei Bestrahlung der Zellen mit UV A Licht. Es wurde ein eindeutiges phototoxisches Potential der TiO2 P25 NP festgestellt. Das Ausmaß der Phototoxizität hing von vielen Faktoren wie beispielsweise der untersuchten Zelllinie, Bestrahlungsdosis, Inkubationsdauer und dem verwendeten Nanomaterial ab. Eine Kombination aus mit Eisen beschichteten TiO2/WO3 NP erwies sich als äußerst effizient in der Abtötung von Krebszellen (HeLa und A549) unter Bestrahlung mit UV-A-Licht. Durch verschiedene in vitro-Assays konnte festgestellt werden, dass sowohl intrazelluläre reaktive Sauerstoffspezies gebildet werden, als auch Apoptose eingeleitet und die Membranintegrität zerstört wird. Für die Anwendung in der photodynamischen Therapie sollte die Effizienz der NP durch Oberflächenmodifizierung verbessert und ein gezielter Wirkstofftransport ermöglicht werden. Die Kopplung des Aptamers Syl3C an vorher an die NP Oberfläche adsorbierte Polyacrylsäure-Moleküle war erfolgreich, konnte die Effizienz der verwendeten NP jedoch nur bedingt verbessern. Für eine zukünftige Anregung des photokatalytischen Prozesses unter Nahinfrarot (NIR) Strahlung wurden außerdem Upconversion-Nanopartikel synthetisiert, die die Umwandlung von NIR Licht (980 nm) in UV-A-Licht ermöglichen.

description: In this paper, we propose a novel approach for texture analysis based on artificial crawler model. Our method assumes that each agent can interact with the environment and each other. The evolution process converges to an equilibrium state according to the set of rules. For each textured image, the feature vector is composed by signatures of the live agents curve at each time. Experimental results revealed that combining the minimum and maximum signatures into one increase the classification rate. In addition, we pioneer the use of autonomous agents for characterizing silk fibroin scaffolds. The results strongly suggest that our approach can be successfully employed for texture analysis.

High-performance fibers developed since the 1960s have a wide range of appli-cations including firefighters' protective clothing. Firefighters' protective cloth-ing made of inherently flame-resistant high-performance fibers offers excellentprotection in the new condition. However, these fibers experience aging as anypolymer material. The situation is amplified due to the severe conditions asso-ciated with the firefighters' activities. And the consequences of a loss in theperformance of the protective clothing can be dramatic for the firefighter'ssafety. This article provides a comprehensively review of the aging behavior ofhigh-performance fibers used in firefighters' protective clothing. Residual per-formance data have been identified both for used firefighter garments as wellas fabric specimens subjected to accelerated aging. Research shows that differ-ent aging conditions affect the different fibers to a different degree. The specificconditions in which the aging is applied also affects the outcome in terms ofloss in performance. Techniques successfully used to quantify the effect ofaging on the performance of fire-resistant fabrics are also briefly mentioned.Finally, the knowledge gained from this analysis of the literature as well asresearch gaps and further areas of investigation are discussed in this neglectedyet critical topic of firefighters' protective clothing aging.

description: Der Fokus der Arbeit liegt auf zwei Effekten, die anhand der lokalisierten Oberflächenplasmonresonanz (LOPR) quasisphärischer Silber Nanopartikel untersucht wurden: Nahfeld-Plasmon-Kopplung und plasmonverstärkte Fluoreszenz. Eine Einkapselung der Silber-Nanopartikel mit Schalen aus amorphem Siliziumdioxid (Silber@Silica) erzeugten zudem verschiedene Abstände zwischen den wechselwirkenden Spezies. Hierdurch wurden die Abstandsabhängigkeiten der verschiedenen Effekte betrachtet. Mit der Lyophilisierung wurde ein Verfahren eingesetzt, das die Silber-Nanostrukturen unter Erhalt ihrer LOPR zu Netzwerken verknüpft. Spektroskopische Untersuchungen ließen erkennen, dass auf die optischen Eigenschaften solcher Netzwerke mehrere Prozesse einwirken. Die Nahfeld-Plasmon-Kopplung zeigte sich dabei in einer spektralen Verschiebung der LOPR zu kürzeren Wellenlängen sowie in einer Zunahme der Linienbreite. Vergrößerte Abstände zwischen den Silber-Nanopartikeln führten wiederum zu optischen Eigenschaften, die denjenigen des eingesetzten Kolloids ähneln. Im Falle der plasmonverstärkten Fluoreszenz beschäftigt sich die Arbeit zunächst mit der Herstellung der Hybridsysteme. Als Fluorophore wurden null-, ein- und zweidimensionale hydrophobe CdSe@CdS-Nanoheterostrukturen eingesetzt. Zudem ließen sich die hydrophoben Fluorophore durch einen Ligandenaustausch mit thiolhaltigen Verbindungen ins wässrige Medium transferieren. Hierzu lieferte eine separate Studie vorab Kenntnisse über die für die Fluoreszenzlöschung relevanten Faktoren. Diesbezüglich beeinträchtigten die infolge des Liganden erzeugten Lochhaftstellen sowie eine mangelhaft passivierte CdSe-Phase die Fluoreszenzeigenschaften der transferierten Nanoheterostrukturen. Wie sich bei der Herstellung der Hybridsysteme herausgestellt hat, stellen die Porosität der Silica-Schale und/oder freie Silber-Spezies signifikante Störfaktoren dar. Die Immobilisierung der Silber@Silica-Nanoheteropartikel in Verbindung mit dem Tropfengussverfahren unter hydrophoben Bedingungen erwies sich jedoch als zielführende Methode. Anhand von Ensemblemessungen konnte hierbei an den null- und eindimensionalen CdSe@CdS-Nanoheterostrukturen eine plasmonverstärkte Fluoreszenz nachgewiesen werden. In diesen Systemen hing die Verstärkung von der Silica-Schalendicke und bei der anisotropen CdSe@CdS-Nanoheterostruktur zusätzlich von deren räumlicher Orientierung ab.

description: Based on the author's experiences with local and state land use planning programs in North Carolina, Florida, and Virginia, this article concludes that the value of technical planning skills must be considered secondary to the more significant and unpredictable world of political reality. To integrate politics into the planning process, the planner must have the determination to see the job through, more than a passing awareness of public relations, and the ability to project fairness above all else.

description: In this paper, a method for the digital simulation of wind velocity fields by Fractional Spectral Moment function is proposed. It is shown that by constructing a digital filter whose coefficients are the fractional spectral moments, it is possible to simulate samples of the target process as superposition of Riesz fractional derivatives of a Gaussian white noise processes. The key of this simulation technique is the generalized Taylor expansion proposed by the authors. The method is extended to multivariate processes and practical issues on the implementation of the method are reported.

description: The vitality of North Carolina depends on strong and vibrant regions. Regions are the interconnected places where people live, work, and recreate. They are also the places where local government problems like environmental protection, traffic, and solid waste spill across municipal boundaries and become shared concerns. More and more one hears the opinion that independent but interrelated places must develop the capacity to work together if these problems are to be addressed and a desired future is to be secured. To paraphrase an old saying about the United Nations, if regions didn't exist, we would have to create them.

We study the effect of the resulting hyperbolic dispersion relations on the black body spectral density. We show that for both of the possible wavevector space topologies, the spectral density vanishes at a certain frequency. We obtain the partition function and derive some thermodynamical quantities of the system. To leading order, the results resemble those of a one- or two-dimensional photon gas with an enhanced density of states.

New Urbanism in Practice
Creators: name: Earnhardt, Jim
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1997

description: In the past 10 years. New Urbanism (also known as traditional neighborhood development or neotraditional planning) has emerged as an important philosophy of land use planning. Correspondingly, numerous articles in industry-specific publications such as Planning, Urban Land, and Landscape Architecture as well as mass audience publications like Newsweek and Consumer Reports, have extolled the virtues and flaws of New Urbanism. This article assumes the reader understands the basic tenets of New Urbanism and has already formed an opinion on its effectiveness as a land planning model. Instead of introducing the concepts, this article focuses on putting the philosophy into practice through a review of a specific New Urban community currently under development from the perspective of a member of the development team. This review includes a description of the evolution of the project from the original idea conception, through the entitlement process, up to the building of the initial phases of the development. In the course of the review, the author identifies both positive and negative consequences resulting from the public and private interaction that is an important and unavoidable part of the development process.
Mesoscopic model for filament orientation in growing actin networks: the role of obstacle geometry

description: Propulsion by growing actin networks is a universal mechanism used in many different biological systems. Although the core molecular machinery for actin network growth is well preserved in most cases, the geometry of the propelled obstacle can vary considerably. In recent years, filament orientation distribution has emerged as an important observable characterizing the structure and dynamical state of the growing network. Here we derive several continuum equations for the orientation distribution of filaments growing behind stiff obstacles of various shapes and validate the predicted steady state orientation patterns by stochastic computer simulations based on discrete filaments. We use an ordinary differential equation approach to demonstrate that for flat obstacles of finite size, two fundamentally different orientation patterns peaked at either +35/-35 or +70/0/-70 degrees exhibit mutually exclusive stability, in agreement with earlier results for flat obstacles of very large lateral extension. We calculate and validate phase diagrams as a function of model parameters and show how this approach can be extended to obstacles with piecewise straight contours. For curved obstacles, we arrive at a partial differential equation in the continuum limit, which again is in good agreement with the computer simulations. In all cases, we can identify the same two fundamentally different orientation patterns, but only within an appropriate reference frame, which is adjusted to the local orientation of the obstacle contour. Our results suggest that two fundamentally different network architectures compete with each other in growing actin networks, irrespective of obstacle geometry, and clarify how simulated and electron tomography data have to be analyzed for non-flat obstacle geometries.

description: We investigate the effect of the $RF^2$ correction on the holographic superconductor model in the background of AdS black hole. We find that, similar to the effect caused by the Weyl correction, the higher $RF^2$ correction term can make it easier for the scalar operator to condense and result in the larger deviations from the expected relation in the gap frequency. However, if a non-trivial hair for the black hole has been triggered, we observe that the $RF^2$ correction and the Weyl correction do play different roles in the behavior of the condensation, which can be used to support the existing findings.

Distributing the Public Cost and Benefits of Growth in the Raleigh-Durham Area
Creators: name: Usher, Charles L.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1981

description: Although the accuracy of economic development models is enhanced by the inclusion of public sector subsystems, one problem which tends to be ignored in most of these models is the imbalance which often arises in the distribution of public costs and benefits. This problem involves two issues. One concerns the degree to which the public costs and benefits of development are distributed equitably among the residents within a single jurisdiction. The other issue pertains to externalities, specifically whether or not there is a significant spillover of costs and benefits from one jurisdiction to another. This report deals with both types of issues over the period from 1960 to 1980 in the Raleigh-Durham area. Among the intrajurisdictional issues which we shall analyze is the degree to which suburban or fringe development in annexed areas has been underwritten by central-city residents, or conversely, the degree to which the property of suburban residents has been exploited as a new tax resource by central cities. If disproportionate shares of the costs and benefits of growth have been realized by certain groups, an inequitable situation will be deemed to exist. A second intrajurisdictional issue we shall examine is the administration of the property tax. Our purpose is to investigate a potential problem involving the equitable imposition of the property tax burden on residents of growing communities. The third intrajurisdictional issue that will be explored is the increasing reliance of growing communities on regressive means of generating public revenue. This trend is best illustrated in the widespread use of user fees.

description: Pathogene Bakterien sind in der Lage sich verschiedenen Umweltbedingungen anzupassen und die Immunantwort des Wirts zu umgehen. Diese Fähigkeit erfordert eine schnelle Anpassung der Genexpression, Translation und des Stoffwechsels auf molekularer Ebene. Das csr-System (carbon storage regulator) ist ein globales Regulationssystem, das zwischen verschiedenen Bakteriengattungen konserviert ist. Das System besteht aus dem dimeren mRNA-bindenden Protein CsrA und kleinen regulatorischen RNAs, die die CsrA-Aktivität unterdrücken. Die regulatorische Funktion von CsrA beruht auf der Bindung des Proteins an GGA-Motive der mRNA, die oft nahe der ribosomalen Bindungsstelle lokalisiert sind. Aufgrund der Bindung von CsrA wird die Ribosomenbindestelle blockiert, sodass eine Translation verhindert wird. In dieser Studie haben wir den globalen Einfluss von CsrA auf den bakteriellen Stoffwechsel unter Verwendung von Hochleistungsflüssigkeitschromatographie und Gaschromatographie, gekoppelt mit Massenspektrometrie, zur weiteren Identifizierung von Metaboliten analysiert. Durch die Kombination verschiedener Chromatographietechniken wurde die Abdeckung des Metaboloms und des Lipidoms maximiert, was Einblick in die regulatorische Funktion von CsrA ermöglichte, indem insgesamt 159 Metaboliten identifiziert wurden. Eine weitere Kombination mit RNA-Sequenzierung führte zu einem Multi-Omics-Ansatz, der das Wissen über die regulatorischen Funktionen des csr-Systems erweiterte. Mit optimierten Wachstumsmedien zur Induktion der Virulenzfaktor-Expression im Modellorganismus EPEC E2348 / 69 beobachteten wir dramatische Veränderungen in der Transkriptom- und Metabolom-Landschaft der ∆csrA Mutante. Mittels Elektronenmikroskopie konnten außerdem dramatische, morphologische Veränderungen in Form von vesikelartigen Strukturen auf der Zelloberfläche beobachtet werden. Dies führte zu der Hypothese, dass dies eine Folge der starken Hochregulierung des Kolonsäuresynthesoperons ist, die auch in den Transkriptomdaten deutlich sichtbar war und durch die Quantifizierung der Kolonsäure- und Exopolyssacharidproduktion im Mutantenstamm unterstützt wurde. Auch andere Stoffwechselwege wie Enterobactin-Biosynthese, Virulenzgenexpression, Kohlenhydratmetabolismus, Synthese aromatischer Aminosäuren, Nucleosid-Salvage-Wege und Lipidmetabolismus wurden ebenfalls stark durch die Deletion von csrA beeinflusst und wurden in der Literatur nicht oder nur teilweise beschrieben.

description: We analyze hadrochemical freeze-out in central Pb+Pb collisions at CERN SPS and LHC energies. Employing the UrQMD hybrid transport model we study the effects of the final hadron/resonance expansion phase on the hadron multiplicities established at hadronization. The bulk meson yields freeze out directly at hadronization whereas the baryon-antibaryon sector is subject to significant alterations, due to annihilation and regeneration processes. We quantify the latter changes by survival factors for each species which are applied to modify the statistical model predictions for the data. The modified SM analysis recovers the hadronization points, which coincide with the recent lattice QCD predictions of the parton-hadron transition line at finite baryochemical potential.

Development Planning For Barrier Island Maritime Forests
Creators: name: Zucchino, Lawrence R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1980

description: During the last twenty years, the importance of ensuring proper land planning and landscape management on barrier islands has been firmly established. Culminating with the passage and implementation of the North Carolina Coastal Area Management Act of 1974, the overall planning and management process for barrier islands has substantially improved the balance between island development activities and the ability of the barrier island to maintain its essential ecological and geomorphological functions and processes. In the context of current comprehensive planning efforts for barrier islands, maritime forests have become the last major component of the island system which has yet to come under strong regulatory control. Although considerable development in maritime forests has occurred in the past, only recently have researchers come to more fully understand the strategic role that maritime forests play in the overall maintenance of the barrier island ecosystem. Growing recognition of the maritime forest's functional importance coupled with the prospect of increased development activity and a firmly entrenched planning and regulatory framework suggests that management of the maritime forests could prove to be a key planning issue on barrier islands in the 1980s.

description: In modernen Flugtriebwerken kommen in den vorderen hochbelasteten Verdichterstufen zunehmend integrale Laufschaufelräder (Blisks) zum Einsatz. Deren Schaufeln sind aufgrund geringer mechanischer Dämpfung empfindlich gegenüber Schwingungen. Im Rahmen dieser Arbeit wurde untersucht, ob reparaturbedingte Varianzen einen negativen Einfluss auf die Stabilität haben. Die Arbeitshypothese ist, dass dieser Einfluss während einer möglichen Reparatur berücksichtigt werden muss. Um den Einfluss von Schaufelreparaturen auf das aeroelastische Verhalten einer Blisk zu charakterisieren, wurde ein einstufiger Axialverdichter ausgelegt, gefertigt und experimentell sowie numerisch untersucht. Dabei kamen eine Referenzblisk und eine Blisk mit Blend-Reparaturen an der Vorderkante einiger Schaufeln zum Einsatz. In Simulation führt die lokale Änderung der Strömung zu einer lokalen Änderung der aerodynamischen Arbeit. Dies beeinflusst vor allem die Eigendämpfung der betrachteten Schaufel sowie die Dämpfung durch die unmittelbar benachbarten Schaufeln. Die größte Änderung tritt für Reparaturen nahe der Schaufelspitze auf. In Abhängigkeit der Position der reparierten Schaufel kann die Dämpfung einer einzelnen Schaufel reduziert werden, während die Dämpfung der Nachbarschaufeln ansteigt. Die experimentelle Untersuchung erfolgte mithilfe eines akustischen Anregungssystems im rotierenden Prüfstand an mehreren Betriebspunkten. Dabei konnte keine signifikante Abnahme der aeroelastischen Stabilität der reparierten Blisk festgestellt werden. Hieraus ergibt sich die Schlussfolgerung, dass aerodynamisches Mistuning infolge von Blend-Reparaturen der Schaufelvorderkante keinen signifikanten Einfluss auf die aeroelastische Stabilität hat und nicht während des Reparaturprozesses berücksichtigt werden muss.

description: Particle pollution in South Korea has become a matter of significant public concern, culminating in its declaration as a “social disaster” through a government proclamation in 2019. This study shows how the existing interventions to tackle particle pollution in South Korea as a “social disaster” contribute to maintaining the status quo, paradoxically. The study attempts to interpret pollution as entanglements, relations, and processes by addressing the discussions and politics surrounding particle pollution, the interventions to tackle it, and what they presuppose and exclude via multi-sited ethnography. What narratives form the bedrock of the current discourses and politics around particle pollution in South Korea? What kinds of population, knowledge systems, values, and interests are incorporated and excluded around particulate matter in Korea? Drawing upon four months of fieldwork, interviews, and collaborative work with residents, scientists, and activists in South Korea, this thesis offers a new understanding of how citizens’ experiences and knowledge practices have reshaped the concepts of pollution, toxicity, and health. The study indicates that the existing practices and knowledge vis-à-vis pollution control have individualized pollution by presuming particular ways of normalcy and excluding others. In doing so, this study captures the multiplicity of particle pollution and shows the existence and stories of different bodies living with/in pollution. Drawing on the literature in feminist science and technology studies as well as medical and environmental anthropology scholarship, this study problematizes harm reduction-based environmental and health intervention practices by describing the current individualized particle pollution responses. The research reveals how people in Korea living with/in particulate matter have perceived, datafied, defined, adjusted, and responded to particle pollution and its toxicity. The study suggests that pollution should be envisaged as entanglements and relations by shedding light on the stories that particulate matter has been perceived, coordinated, and generated in various ways. Lastly, indicating that the knowledge and interventions surrounding particle pollution have exploited and flattened the environment based on the human–nature dichotomy, the study suggests different ways of conceptualizing pollution, while considering the multiplicity of pollution, toxicities, and bodies.

description: In this paper we consider square functions (also called Littlewood-Paley g-functions) associated to Hankel convolutions acting on functions in the Bochner-Lebesgue space $L^p((0,\infty),B)$, where $B$ is a UMD Banach space. As special cases we study square functions defined by fractional derivatives of the Poisson semigroup for the Bessel operator $Δ_λ=-x^{-λ}\frac{d}{dx}x^{2λ}\frac{d}{dx}x^{-λ}$, $λ>0$. We characterize the UMD property for a Banach space $B$ by using $L^p((0,\infty),B)$-boundedness properties of g-functions defined by Bessel-Poisson semigroups. As a by product we prove that the fact that the imaginary power $Δ_λ^{iw}$, $w\in \mathbb{R}\setminus\{0\}$, of the Bessel operator $Δ_λ$ is bounded in $L^p ((0,\infty),B)$, $1
Buildings, Manners and Laws: The Charleston Single House as a Definer of Urban Form and Shaper of City Life

description: When Charles Town was incorporated as Charleston, South Carolina in 1783, just over 100 years after being established, she adopted as her municipal motto the Latin phrase Aedes, Mores Legaque Curat - "she takes care of her buildings, her manners and her laws." It tells a lot about what kind of place Charleston is. The buildings I want to talk about here are houses, one particular - and particular to Charleston - house type especially. It is known as the "single house." There are, as I will show, particular ways of living - manners - that go with this kind of house and with a city made up of these houses. There may not ever have been any laws in Charleston regulating building types (though there were, and continue to be, plenty of building regulations) but there seems to have been something that urged individuals in a similar direction over a long period of time. And it certainly is the case that some general principles - rules, if not quite laws - can be drawn from an examination of Charleston domestic architecture that are still suitable for use today.

description: We show that the dark energy effects can be modeled by using an \emph{Ising perfect fluid} with network interactions, whose low redshift equation of state, i.e. $ω_0$, becomes $ω_0=-1$ as in the $Λ$CDM model. In our picture, dark energy is characterized by a barotropic fluid on a lattice in the equilibrium configuration. Thus, mimicking the spin interaction by replacing the spin variable with an occupational number, the pressure naturally becomes negative. We find that the corresponding equation of state mimics the effects of a variable dark energy term, whose limiting case reduces to the cosmological constant $Λ$. This permits us to avoid the introduction of a vacuum energy as dark energy source by hand, alleviating the coincidence and fine tuning problems. We find fairly good cosmological constraints, by performing three tests with supernovae Ia, baryonic acoustic oscillation and cosmic microwave background measurements. Finally, we perform the AIC and BIC selection criteria, showing that our model is statistically favored with respect to the CPL parametrization.
