description: Standard discussions of Goldstone's theorem based on a symmetry of the action assume constant fields and global transformations, i.e., transformations which are independent of spacetime coordinates. By allowing for arbitrary field distributions in a general representation of the symmetry we derive a generalization of the standard Goldstone's theorem. When applied to gauge bosons coupled to scalars with a spontaneously broken symmetry the generalized theorem automatically imposes the Higgs mechanism, i.e. the gauge bosons become massive. The other aspect of the Higgs mechanism, the disappearance of the would-be Goldstone boson, follows directly from the generalized symmetry condition itself. We also use our generalized Goldstone's theorem to analyze the case of a system in which scale and conformal symmetries are both spontaneously broken.

Politics and Urban Development Focus on Jakarta’s Shopping Center Trajectory

description: "City of consumerism" seems to be an appropriate moniker for Jakarta, the capital city of Indonesia. Over the past few years, Jakarta has transformed from an administrative town where both state and local public authorities exercise policy and development strategy — into an economic empire of the nation. Economic indicators pointed out that the economic development in the metropolitan region is massive; 6 percent economic growth, rising middle-class’ purchasing power, and increasing foreign property investment. Urban scholars have highlighted that this urban transformation is much influenced by modern world-class city aspiration driven by the private sectors who are able to display grandiose modern projects and influence the policy makers. One of the many phenomena that shows this urban revolution is the booming of shopping center development in the metropolitan region. Currently, Jakarta Metropolitan Region has 153 shopping centers, supplying more than 5 million square meter retail spaces to the 30 million metropolitan population. I argue that the enormous number of shopping center operated in the city comes as the result of the shifting urban development focus towards neoliberalism bounded to an intricate economic, political, and ideological system of the nation. Using urban historical framework and the mapping techniques, I seek to analyze the urban transformation through the shopping center perspective. I further evaluate series of implications — supported by data and facts — that emerge from the shopping center deployment.

Definable transformation to normal crossings over Henselian fields with separated analytic structure

description: We are concerned with rigid analytic geometry in the general setting of Henselian fields $K$ with separated analytic structure, whose theory was developed by Cluckers--Lipshitz--Robinson. It unifies earlier work and approaches of numerous mathematicians. Separated analytic structures admit reasonable relative quantifier elimination in a suitable analytic language. However, the rings of global analytic functions with two kinds of variables seem not to have good algebraic properties such as Noetherianity or excellence. Therefore the usual global resolution of singularities from rigid analytic geometry is no longer at our disposal. Our main purpose is to give a definable version of the canonical desingularization algorithm (the hypersurface case) due to Bierstone--Milman so that both these powerful tools are available in the realm of non-Archimedean analytic geometry at the same time. It will be carried out within a category of definable, strong analytic manifolds and maps, which is more flexible than that of affinoid varieties and maps. Strong analytic objects are those definable ones that remain analytic over all fields elementarily equivalent to $K$. This condition may be regarded as a kind of symmetry imposed on ordinary analytic objects. The strong analytic category makes it possible to apply a model-theoretic compactness argument in the absence of the ordinary topological compactness. On the other hand, our closedness theorem enables application of resolution of singularities to topological problems involving the topology induced by valuation. Eventually, these three results will be applied to such issues as the existence of definable retractions or extending continuous definable functions.

description: A deep learning approach based on big data is proposed to locate broadband acoustic sources using a single hydrophone in ocean waveguides with uncertain bottom parameters. Several 50-layer residual neural networks, trained on a huge number of sound field replicas generated by an acoustic propagation model, are used to handle the bottom uncertainty in source localization. A two-step training strategy is presented to improve the training of the deep models. First, the range is discretized in a coarse (5 km) grid. Subsequently, the source range within the selected interval and source depth are discretized on a finer (0.1 km and 2 m) grid. The deep learning methods were demonstrated for simulated magnitude-only multi-frequency data in uncertain environments. Experimental data from the China Yellow Sea also validated the approach.

Politics, infrastructure and non-human subjects: The Inka occupation of the Amaybamba cloud forests
Creators: Wilkinson, Darryl A.
Publisher: name: Columbia University
Year: 2013
Subjects: Archaeology

description: This dissertation presents the results of an archaeological study of the Inka occupation and transformation of the Amaybamba Valley, Peru, during the Late Horizon, just prior to the Spanish Conquest. This region lies among the dense cloud forests of the eastern Andes, and was situated at the northwestern edges of the Inka heartland centered around the former imperial capital of Cuzco. The main interest for the Inkas in the Amaybamba lay in its capacity to produce large amounts of coca, a plant which was the foundation of a great many exchange relationships across the Andes. Not only was it central to exchanges between humans, but also with the most important non-human powers of the Inka world. These powers included major landscape entities, such as the mountains (apukuna) and other kinds of earth beings (often in the form of rock outcrops, or lakes, known as wak'as). The main focus of this dissertation is the question of how these entities were made subjects of the Inka polity. The broader theoretical framework that underpins my thesis is what I refer to as `political ontology', from which I argue for taking a `step-back' from more traditional (post-Enlightenment) accounts of politics which assume the state is a set of relationships between human actors only, and thereby consider the possibility of non-modern states in which other-than-human beings could be made into political subjects. The Amaybamba is thus presented as a case-study through which we can examine the empirical, archaeological traces of just such processes of subjectification. The Inka presence in the Amaybamba mainly took the form of a series of royal landholdings, which were associated with a number of aristocratic lineages within the empire. My arguments therefore have broader implications for how we understand the royal estate system more generally. In particular, I suggest that the royal estates - which appear from our Western perspective to resemble a series of elite-owned plantations - were in Inka eyes seen more as a means to discipline and control the productive capacities of a potent community of non-humans.

description: Objectives: Patient reported outcomes are widely used in today’s clinical practice. The Short Health Scale has been proven to be an easy-to-use and reliable measure to evaluate quality of life in patients with inflammatory bowel disease. We aimed to validate this Short Health Scale in Dutch speaking patients. Methods: A total of 157 Crohn’s disease and ulcerative colitis patients (46% male, median age 39 years) completed the Short Health Scale on a tablet during the outpatient clinic. Validity was assessed by correlating both individual and total Short Health Scale scores with short Inflammatory Bowel Disease Questionnaire dimensions and clinical disease activity. Test-retest reliability was assessed in eight patients in stable remission who completed the Short Health Scale a second time after 4–8 weeks. Results: All Short Health Scale items correlated with corresponding short Inflammatory Bowel Disease Questionnaire dimensions (correlation coefficients ranging from −0.403 to −0.833, all p p s between 0.699 and 0.994, all p Conclusions: The Short health Scale is a rapid and valid instrument for measuring quality of life in Dutch speaking patients with Inflammatory Bowel Disease. Its simplicity and usability make it a good candidate for routine care and suitable for home-monitoring of patients.

Influence of an inert charged Higgs boson on the muon $g-2$ and radiative neutrino masses in a scotogenic model

description: A simple extension of Ma's approach in a scotogenic model is studied for the purpose of simultaneously interpreting the neutrino data and the excess of muon anomalous magnetic moment (muon $g-2$). The feasible minimal extension is to add an $Z_2$-odd vector-like lepton doublet to the Ma's model. It is found that in addition to the neutrino data, the strict constraints on the relevant parameters are from the electroweak oblique parameters and the induced lepton-flavor violation processes, such as $\ell_i \to \ell_j γ$ and $\ell_i \to \ell^-_j \ell^-_j \ell^+_j$. Performing parameter scan, we numerically demonstrate that when the constraint conditions are satisfied, the muon $g-2$ of $O(10^{-9})$ can be achieved, where it can be expected that with a $5σ$ observation, the Muon $g-2$ experiment at Fermilab can observe $a_μ\approx 13.31 \times 10^{-10}$ when the current experiment and the SM errors are reduced by a factor of 4 and 2, respectively. Moreover, the branching ratio of the $τ\to μγ$ decay can match the Belle II sensitivity of $O(10^{-9})$ with an integrated luminosity of 50 ab$^{-1}$.

For an explanation models with several mechanisms and consequently many parameters as the Lux-Marchesi model have been used. We show that a simple herding model with only four parameters leads to a quantitative description of the data. As a new type of data we describe the volatility cluster by the waiting time distribution, which can be used successfully to distinguish between different models.

Can the entanglement entropy be the origin of black-hole entropy ?

Year: 1997
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Entanglement entropy is often speculated as a strong candidate for the origin of the black-hole entropy. To judge whether this speculation is true or not, it is effective to investigate the whole structure of thermodynamics obtained from the entanglement entropy, rather than just to examine the apparent structure of the entropy alone or to compare it with that of the black hole entropy. It is because entropy acquires a physical significance only when it is related to the energy and the temperature of a system. From this point of view, we construct a `thermodynamics of entanglement' by introducing an entanglement energy and compare it with the black-hole thermodynamics. We consider two possible definitions of entanglement energy. Then we construct two different kinds of thermodynamics by combining each of these different definitions of entanglement energy with the entanglement entropy. We find that both of these two kinds of thermodynamics show significant differences from the black-hole thermodynamics if no gravitational effects are taken into account. These differences are in particular highlighted in the context of the third law of thermodynamics. Finally we see how inclusion of gravity alter the thermodynamics of the entanglement. We give a suggestive argument that the thermodynamics of the entanglement behaves like the black-hole thermodynamics if the gravitational effects are included properly. Thus the entanglement entropy passes a non-trivial check to be the origin of the black-hole entropy.

Dominion (Gurney) Minesite Rehabilitation

Year: 2013

description: The Dominion (Gurney) Mine Site is located in the Grass River Provincial Park in the mid-western portion of Manitoba, approximately 560 km northwest of Winnipeg, Manitoba. The site is accessible by air or ATV/snowmobile trail. A private railway provides access to a staging area approximately 5 km from the site. Between 1933 and 1939, The Dominion (Gurney) Mine extracted and processed 94,650 tonnes of ore until reserves were exhausted. The mine was closed in 1939 and little exploration has occurred at the site since that time. At the time of assessment, the Mine Site consisted of several remnant building structures, metal and wood debris, a waste rock pile, an acid generating tailings area and five mine openings. The engineering team and construction contractor had to address and overcome several challenges largely driven by the location of the site. The challenges affecting the Dominion rehabilitation program included northern climatic conditions, limited access, its location in a Provincial Park, First Nation concerns and requirements for their involvement in the rehabilitation, the necessity of addressing local concerns and providing local economic benefits. This paper presents a summary of the site investigation, hazard classification, design of the remedial measures, construction challenges and design modifications to address changing conditions. Rehabilitation included construction of an access road, consolidation of wood and metal debris, concrete rubble, tailings and waste rock under a composite soil and geomembrane cover and sealing of the mine openings.

description: Extreme high-energy peaked BL Lac objects (EHBLs) are an emerging class of blazars with exceptional spectral properties. The non-thermal emission of the relativistic jet peaks in the spectral energy distribution (SED) plot with the synchrotron emission in X-rays and with the gamma-ray emission in the TeV range or above. These high photon energies may represent a challenge for the standard modeling of these sources. They are important for the implications on the indirect measurements of the extragalactic background light, the intergalactic magnetic field estimate, and the possible origin of extragalactic high-energy neutrinos. In this paper, we perform a comparative study of the multi-wavelength spectra of 32 EHBL objects detected by the Swift-BAT telescope in the hard X-ray band and by the Fermi-LAT telescope in the high-energy gamma-ray band. The source sample presents uniform spectral properties in the broad-band SEDs, except for the TeV gamma-ray band where an interesting bimodality seems to emerge. This suggests that the EHBL class is not homogeneous, and a possible sub-classification of the EHBLs may be unveiled. Furthermore, in order to increase the number of EHBLs and settle their statistics, we discuss the potential detectability of the 14 currently TeV gamma-ray undetected sources in our sample by the Cherenkov telescopes.

description: In a previous paper, a bound on the negative energy density seen by an arbitrary inertial observer was derived for the free massless, quantized scalar field in four-dimensional Minkowski spacetime. This constraint has the form of an uncertainty principle-type limitation on the magnitude and duration of the negative energy density. That result was obtained after a somewhat complicated analysis. The goal of the current paper is to present a much simpler method for obtaining such constraints. Similar ``quantum inequality'' bounds on negative energy density are derived for the electromagnetic field, and for the massive scalar field in both two and four-dimensional Minkowski spacetime.

description: Polygenic adaptation in response to selection on quantitative traits is thought to be ubiquitous in humans and other species, yet this mode of adaptation remains poorly understood. We investigate the dynamics of this process, assuming that a sudden change in environment shifts the optimal value of a highly polygenic quantitative trait. We find that when the shift is not too large relative to the genetic variance in the trait and this variance arises from segregating loci with small to moderate effect sizes (defined in terms of the selection acting on them before the shift), the mean phenotype's approach to the new optimum is well approximated by a rapid exponential process first described by Lande (1976). In contrast, when the shift is larger or large effect loci contribute substantially to genetic variance, the initially rapid approach is succeeded by a much slower one. In either case, the underlying changes to allele frequencies exhibit different behaviors short and long-term. Over the short term, strong directional selection on the trait introduces small differences between the frequencies of minor alleles whose effects are aligned with the shift in optimum versus those with effects in the opposite direction. The phenotypic effects of these differences are dominated by contributions from alleles with moderate and large effects, and cumulatively, these effects push the mean phenotype close to the new optimum. Over the longer term, weak directional selection on the trait can amplify the expected frequency differences between opposite alleles; however, since the mean phenotype is close to the new optimum, alleles are mainly affected by stabilizing selection on the trait. Consequently, the frequency differences between opposite alleles translate into small differences in their probabilities of fixation, and the short-term phenotypic contributions of large effect alleles are largely supplanted by contributions of fixed, moderate ones.

description: Polychlorinated Biphenyls (PCBs) are hazardous organic compounds best known for their use in transformers and electrical capacitors because of their non-combustibility and flexibility. Lesser known, but widespread, use in caulking, finishes, and paint is now coming to light because of health risks, particularly associated with their prevalence in schools. Humans can be exposed to PCBs in numerous ways: through deteriorating caulk that makes its way to the soil by rain run-off, by breathing contaminated air, or by dermal contact with the material. This thesis will give a brief introduction to the history of PCBs in building construction from about 1950 to 1980 before production, sale, and disposal was regulated through the Toxic Substance Control Act (TSCA). The TSCA was one of a group of acts passed in the 1970’s to improve the quality of the environment including the Clean Air Act, Federal Water Pollution Control Act, and Safe Drinking Water Act. Although it will decrease the amount in the environment, proper removal of PCBs may have implications for historic buildings. Because PCBs often migrate into porous adjacent substrate, original materials may have to be abated as well. I was introduced to the topic of polychlorinated biphenyls during a summer internship when a client did not want to re-point within six inches of the windows on their historic building for fear of PCBs in the caulk. Partial re-pointing would have a detrimental effect on the appearance of the façade. This thesis will be illustrated with case studies of buildings containing PCBs and how they were managed. PCB abatement will continue to be a concern, especially in urban areas, because they are most commonly found in apartment buildings, schools, and larger office buildings. New York in particular has been examining PCB contamination in public schools. P.S. 199 in Manhattan, a 1963 building by noteworthy architect Edward Durell Stone is a prime example of New York City’s push to remove PCBs from public schools. The building was part of an initial PCB pilot study. A second case study is Westgate Dormitory at MIT where several brick courses contaminated with PCBs were removed. Case study three will focus on PCB migration in a concrete building on UMass Amherst’s campus. I will compare the techniques for abatement from the case studies to determine what parallels can be drawn. This thesis will give preservation instructions for buildings containing PCBs by providing a PCB abatement approach that is sensitive to the preservation of historic structures.

Polyelectrolyte-Surfactant Phase Behavior and Mechanisms of Interaction in Multi-Component Systems
Creators: Martinez-Santiago, Jose
Publisher: name: Columbia University

description: Polymer-Surfactant (P-S) systems and their implications both in industry and academia have been studied for the last fifty years. Despite the fact that the majority of synthetic and biological systems have a multicomponent nature, most previous studies focused on molecular interactions of individual polymers and surfactants in aqueous solutions, at the air/water interface or at the solid/water interface. P-S interactions in multicomponent systems have not received sufficient attention. Among the important issues that remain unresolved, the following are of particular significance: a) lack of information on P-S systems phase behavior in the presence of a third component which is widely used in industrial applications and of academic interest, b) insufficient quantitative information on competitive interactions of all species in the system and uncertainty on how molecules conform upon interaction and, c) lack of mathematical models to describe P-S interactions in a multicomponent environment.
      To address the unresolved issues, a study focusing on the mechanisms of interaction of an oppositely charged polyelectrolyte-surfactant (PE-S) pair in the presence of fatty acid (FA) was carried out. Experimental results using surface tensiometry, light scattering, zeta potential and, nuclear magnetic resonance (NMR) showed that the FA solubility in the system determined the overall phase behavior of the multicomponent mixture.
      In a system containing FA at a concentration above the solubilization limit of the surfactant, FAs form solid aggregates.  Such aggregates were found to possess a considerable negative surface charge, consequently, preferential binding of the polycation to FA aggregates was observed and the usual tendency of PE-S pair to form a complex was inhibited. These results were useful to understand the polyelectrolyte-induced flocculation disruption by FA aggregates in emulsions systems.
      In a system containing FA at a concentration below the solubilization limit of the surfactant, the FA was found to be mostly solubilized forming mixed micelles with the surfactant. NMR revealed detailed information on the competitive binding behavior of both the fatty acid and the surfactant, including the morphology of aggregates at the polymer chain. Furthermore, solid state NMR showed how the structure and composition of the actual PE-S complex changed in the presence of FA.
      Finally, the law of mass action model is successfully employed to describe the PE-S surface tension profile in the presence of FAs.

description: We study the screening mechanism in the most general scalar-tensor theories that leave gravitational waves unaffected and are thus compatible with recent LIGO/Virgo observations. Using the effective field theory of dark energy approach, we consider the general action for perturbations beyond linear order, focussing on the quasi-static limit. When restricting to the subclass of theories that satisfy the gravitational wave constraints, the fully nonlinear effective Lagrangian contains only three independent parameters. One of these, $β_1$, is uniquely present in degenerate higher-order theories. We compute the two gravitational potentials for a spherically symmetric matter source and we find that for $β_1 \ge 0$ they decrease as the inverse of the distance, as in standard gravity, while the case $β_1 < 0$ is ruled out. For $β_1 > 0$, the two potentials differ and their gravitational constants are not the same on the inside and outside of the body. Generically, the bound on anomalous light bending in the Solar System constrains $β_1 \lesssim 10^{-5}$. Standard gravity can be recovered outside the body by tuning the parameters of the model, in which case $β_1 \lesssim 10^{-2}$ from the Hulse-Taylor pulsar.

Use of ecological risk assessment to guide remediation at the Teck Pinchi Lake Mercury Mine

description: The Pinchi Mine roasted cinnabar ore to recover metallic mercury, operating from 1940 to 1944 (historic) and from 1968 to 1975 (modern). After 1975, it was placed under long-term care and maintenance until remediation began in 2002. Waste materials from both operations remain on site, within the lake (historic operation), a Tailings Facility (modern) and other discrete locations. From 2004 – 2009 a terrestrial ecological risk assessment (ERA) was undertaken relying on literature, field investigations, habitat surveys, spatially explicit food chain modeling, and development of toxicity reference values for methylmercury and other metals. Ecological risks were evaluated for 40 wildlife species. Only those species feeding primarily on insects or on small mammals indicated potential risks, mainly from arsenic, inorganic mercury, and methyl mercury from the Mill Site and Tailings Facility. A post-closure risk reduction analysis indicated that remediation of these areas would reduce risks to wildlife to levels acceptable by risk managers. Other areas, with elevated inorganic mercury in soils were deemed to pose negligible to moderate risk and were not targeted for remediation, based on a weighed evaluation of potential risks to wildlife from contamination versus disturbance to naturally recovering habitat.

Molecular probes

description: This doctoral thesis details a series of projects at the border of chemistry and neuroscience leading to the development of a novel family of probes which chemically target specific cells and molecules in the brain. Chapter 1 concisely introduces the history, development and applications of probes for monitoring brain activity and highlights synthetic voltage sensitive dyes as probes which have not yet reached their full potential, partly due to the lack of targeting strategies in brain tissue. Chapter 2 details the development of a new class of polymer-supported probes for ligand-directed delivery of fluorescent voltage sensitive dyes to monoaminergic neurons in live brain tissue. The polysaccharide dextran equipped with dichloropane as a ligand and either an electrochromic or PeT-based voltage sensor selectively targets dopaminergic and noradrenergic axons in mouse brain slice preparations. The new probes enabled voltage imaging in a defined neuronal population without the use of genetic manipulation. All following chapters describe modification of one of the components of the targeting platform developed in Chapter 2 aiming to optimize its performance or broaden its application potential. Chapter 3 extends the developed polymer platform to the targeting of a different molecular target – the AMPA-type glutamate receptor – via a ligand-directed covalent labeling strategy. Chapter 4 examines PEG as an alternative polymer carrier and shows that while dextran is more universal as a carrier, PEG provides superior targeting selectivity with negatively charged PeT-based voltage sensors. A series of targetable probes with improved voltage sensitivity based on the PEG platform is introduced here as well. Chapter 5 describes the synthesis of targetable probes carrying voltage sensors for imaging modalities other than visible light fluorescence, specifically for short wave infrared (SWIR) fluorescence and photoacoustic (PA) imaging. Chapter 6 shows the first steps towards adapting the delivery platform to the development of dual-ligand drugs for cell-selective pharmacology in the brain.
Toxin-mediated competition in weakly motile bacteria

description: Many bacterial species produce toxins that inhibit their competitors. We model this phenomenon by extending classic two-species Lotka-Volterra competition in one spatial dimension to incorporate toxin production by one species. Considering solutions comprising two adjacent single-species colonies, we show how the toxin inhibits the susceptible species near the interface between the two colonies. Moreover, a sufficiently effective toxin inhibits the susceptible species to such a degree that an `inhibition zone' is formed separating the two colonies. In the special case of truly non-motile bacteria, i.e. with zero bacterial diffusivity, we derive analytical expressions describing the bacterial distributions and size of the inhibition zone. In the more general case of weakly motile bacteria, i.e. small bacterial diffusivity, these two-colony solutions become travelling waves. We employ numerical methods to show that the wavespeed is dependent upon both interspecific competition and toxin strength; precisely which colony expands at the expense of the other depends upon the choice of parameter values. In particular, a sufficiently effective toxin allows the producer to expand at the expense of the susceptible, with a wavespeed magnitude that is bounded above as the toxin strength increases. This asymptotic wavespeed is independent of interspecific competition and due to the formation of the inhibition zone; when the colonies are thus separated, there is no longer direct competition between the two species and the producer can invade effectively unimpeded by its competitor. We note that the minimum toxin strength required to produce an inhibition zone increases rapidly with increasing bacterial diffusivity, suggesting that even moderately motile bacteria must produce very strong toxins if they are to benefit in this way.
