description: In this thesis we study the propagation of time-harmonic electromagnetic waves through periodic media for two different regimes. In the first part, we consider a periodic medium in a bounded domain with a period that is much smaller than the wavelength of the electromagnetic wave hitting the medium. The medium is a periodic assembly of conducting microstructures and void space. In order to describe the effective behaviour of the field propagating through this medium, we homogenise the time-harmonic Maxwell equations. There is a vast literature on homogenising Maxwell's equations under rather restrictive assumptions on the (conducting) microstructure. Using a new averaging method---the so-called geometric average---allows us to consider a large class of microstructures that have not been treated before in the literature. We derive the effective Maxwell equations for two cases: perfectly conducting microstructures and highly conductive microstructures. The second part of this thesis is concerned with the propagation of electromagnetic waves in a closed, unbounded and periodic waveguide. In this part we assume that the wavelength of the fields and the period of the medium are of the same order. Imposing suitable assumptions on the geometry and the fields, Maxwell's equations reduce to a scalar Helmholtz equation. We truncate the waveguide to obtain a bounded domain and replace the radiation condition at infinity appropriately. In order to establish the existence of a solution to the Helmholtz equation in this bounded periodic waveguide, we derive a limiting absorption principle for sesquilinear forms. Using this principle, we show that up to an at most countable set of singular frequencies there exists a unique solution to the Helmholtz equation in the bounded waveguide that satisfies the replacement of the radiation condition at infinity.

description: Background: Proposals to expand Medicare coverage tend to be expensive, but the value of
services purchased is not known. This study evaluates the efficiency of the average private
supplemental insurance plan for Medicare recipients.
Methods: Data from the National Health Interview Survey, the National Death Index, and the
Medical Expenditure Panel Survey were analyzed to estimate the costs, changes in life expectancy,
and health-related quality of life gains associated with providing private supplemental insurance
coverage for Medicare beneficiaries. Model inputs included socio-demographic, health, and health
behavior characteristics.
Parameter estimates from regression models were used to predict quality-adjusted life years
(QALYs) and costs associated with private supplemental insurance relative to Medicare only.
Markov decision analysis modeling was then employed to calculate incremental cost-effectiveness
ratios.
Results: Medicare supplemental insurance is associated with increased health care utilization, but
the additional costs associated with this utilization are offset by gains in quality-adjusted life
expectancy. The incremental cost-effectiveness of private supplemental insurance is approximately
$24,000 per QALY gained relative to Medicare alone.
Conclusion: Supplemental insurance for Medicare beneficiaries is a good value, with an
incremental cost-effectiveness ratio comparable to medical interventions commonly deemed
worthwhile.

description: Stellar multiplicity properties have been studied for much of the range from the lowest to the highest stellar masses, but intermediate-mass stars from F-type to late A-type have received relatively little attention. Here we report on a Gemini/NICI snapshot imaging survey of 138 such stars in the young Scorpius-Centaurus (Sco-Cen) region, for the purpose of studying multiplicity with sensitivity down to planetary masses at wide separations. In addition to two brown dwarfs and a companion straddling the hydrogen burning limit we reported previously, here we present 26 new stellar companions and determine a multiplicity fraction within 0.1"--5.0" of 21+/-4%. Depending on the adopted semi-major axis distribution, our results imply a total multiplicity in the range of ~60--80%, which further supports the known trend of a smoothly continuous increase in the multiplicity fraction as a function of primary stellar mass. A surprising feature in the sample is a distinct lack of nearly equal-mass binaries, for which we discuss possible reasons. The survey yielded no additional companions below or near the deuterium-burning limit, implying that their frequency at >200 AU separations is not quite as high as might be inferred from previous detections of such objects within the Sco-Cen region.

description: Background: We set out to describe the risk of hospitalization from heart disease, stroke, and
diabetes among persons born in India, all foreign-born persons, and U.S.-born persons residing in
New York City.
Methods: We examined billing records of 1,083,817 persons hospitalized in New York City during
the year 2000. The zip code of each patient's residence was linked to corresponding data from the
2000 U.S. Census to obtain covariates not present in the billing records. Using logistic models, we
evaluated the risk of hospitalization for heart disease, stroke and diabetes by country of origin.
Results: After controlling for covariates, Indian-born persons are at similar risk of hospitalization
for heart disease (RR = 1.02, 95% confidence interval 1.02, 1.03), stroke (RR = 1.00, 95% confidence
interval, 0.99, 1.01), and diabetes mellitus (RR = 0.96 95% confidence interval 0.94, 0.97) as nativeborn
persons. However, Indian-born persons are more likely to be hospitalized for these diseases
than other foreign-born persons. For instance, the risk of hospitalization for heart disease among
foreign-born persons is 0.70 (95% confidence interval 0.67, 0.72) and the risk of hospitalization for
diabetes is 0.39 (95% confidence interval 0.37, 0.42) relative to native-born persons.
Conclusions: South Asians have considerably lower rates of hospitalization in New York than
reported in countries with national health systems. Access may play a role. Clinicians working in
immigrant settings should nonetheless maintain a higher vigilance for these conditions among
Indian-born persons than among other foreign-born populations.

description: (Abridged) Some supernovae (SNe) may be powered by the interaction of the SN ejecta with a large amount of circumstellar matter (CSM). Here we outline a method to measure the mass of the optically thick CSM around such SNe. We present observations of SN2010jl, including the first detection of a SN using NuSTAR. The total radiated luminosity of SN2010jl is extreme, at least 9e50 erg. By modeling the visible-light data, we robustly show that the mass of the circumstellar material within ~1e16 cm of the progenitor was in excess of 10 solar masses, likely ejected tens of years prior to the SN explosion. Our modeling suggests that the shock velocity during shock breakout was ~6000 km/s, decelerating to ~2600 km/s about two years after maximum light. Our late-time NuSTAR+XMM spectra of the SN presumably provide the first direct measurement of SN shock velocity two years after the SN maximum light -- measured to be in the range of 2000 to 4500 km/s if the ions and electrons are in equilibrium, and >~2000 km/s if they are not in equilibrium. This measurement is in agreement with the shock velocity predicted by our modeling of the optical data. We also show that the mean radial density distribution of the CSM roughly follows an r^-2 law. A possible explanation for the massive CSM with a wind-like profile is that they are the result of multiple pulsational pair instability events prior to the SN explosion, separated from each other by years.

The body politic: the relationship between stigma and obesity-associated disease
Creators: name: Muennig, Peter A.
Publisher: name: Columbia University
Year: 2008
Subjects: Medicine
Psychophysiology

description: Background: It is commonly believed that the pathophysiology of obesity arises from adiposity.
In this paper, I forward a complementary explanation; this pathophysiology arises not from
adiposity alone, but also from the psychological stress induced by the social stigma associated with
being obese.
Methods: In this study, I pursue novel lines of evidence to explore the possibility that obesity associated
stigma produces obesity-associated medical conditions. I also entertain alternative
hypotheses that might explain the observed relationships.
Results: I forward four lines of evidence supporting the hypothesis that psychological stress plays
a role in the adiposity-health association. First, body mass index (BMI) is a strong predictor of
serological biomarkers of stress. Second, obesity and stress are linked to the same diseases. Third,
body norms appear to be strong determinants of morbidity and mortality among obese persons;
obese whites and women – the two groups most affected by weight-related stigma in surveys –
disproportionately suffer from excess mortality. Finally, statistical models suggest that the desire
to lose weight is an important driver of weight-related morbidity when BMI is held constant.
Conclusion: Obese persons experience a high degree of stress, and this stress plausibly explains
a portion of the BMI-health association. Thus, the obesity epidemic may, in part, be driven by social
constructs surrounding body image norms.

description: Photon number splitting is observed in a transmon coupled to a superconducting quasi-lumped-element resonator in the strong dispersive limit. A thermal population of 5.474 GHz photons at an effective resonator temperature of T = 120mK results in a weak n = 1 photon peak along with the n = 0 photon peak in the qubit spectrum in the absence of a coherent drive on the resonator. Two-tone spectroscopy using independent coupler and probe tones reveals an Autler-Townes splitting in the thermal n = 1 photon peak. The observed effect is explained accurately using the four lowest levels of the dispersively dressed qubit-resonator system and compared to results from numerical simulations of the steady-state master equation for the coupled system.

This diagram illustrates 10 dairy cows diagnosed with S. aureus clinical mastitis from five dairy herds in Quebec, Canada. All mastitis occurred via natural infections. Milk samples (n = 599) were collected from all four quarters bi-weekly. Identifiers of each cow name are ‘H’ for the herd and ‘C’ for the assigned cow number. The red and the blue square boxes represent clinical mastitis with visible symptoms infected by S. aureus and other mastitis pathogens, respectively. The black square boxes represent non-mastitic milk. The open square boxes regardless of colors indicate milk samples where no 16S rRNA data is available due to missing milk samples (n = 16), low bacterial DNA (n = 6), and low library read size (n = 10). Fig. S2 Groups of dairy cows. A total of ten dairy cows (11 quarters) affected by S. aureus clinical mastitis were grouped based on the relative abundance of Staphylococcus at Week 0. Two quarters, a healthy and a CM quarter, were selected and indicated under the name of each cow. At Week 0, Staphylococcus was solely the predominant genus in mastitic milk samples in Group I while it was barely detectable in Group II with relative abundance of less than 10%. Fig. S3 Relative abundance of 11 OTUs and OTU0001 (Staphylococcus) over the lactation in healthy and mastitic quarters. The line graphs depict the changes of the relative abundance of 11 OTUs and OTU0001 in two quarters (healthy vs. mastitic quarters) from each cow over the study period. The vertical dotted lines indicate either beginning or ending of S. aureus CM.

p-wave superconductors in dilaton gravity

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

description: In this paper, we study peculiar properties of p-wave superconductors in dilaton gravity. The scale invariance of the bulk geometry is effectively broken due to the existence of dilaton. By coupling the dilaton to the non-Abelian gauge field, i.e., $-\frac14 e^{-βΦ} F^a_{μν}F^{aμν}$, we find that the dissipative conductivity of the normal phase decreases and approaches zero at the zero frequency as $β$ increases. Intuitively, the system behaves more and more like an insulator. When the hairy solution is turned on, the system crosses a critical point to the superconducting phase. We find that the critical chemical potential decreases with the increasing of $β$ and the maximum height of the conductivity is suppressed gradually which are consistent with our intuition for insulator/supercondutor transition.

description: Newcomers to jazz often ask: Is it true that jazz is all improvised? Somehow the casual and romantic notion that jazz is generated in an entirely spontaneous manner has become deeply rooted in our society. The notator of any jazz solo, or blues, has no chance of capturing what in effect are the most important elements of the music. . . . A printed musical example of an Armstrong solo, or of a Thelonious Monk solo, tells us almost nothing except the futility of formal musicology when dealing with jazz. The difficulty of applying standard infringement measures to musical compositions in a way that will properly protect the plaintiff’s original expression and the defendant’s freedom to create original expression of his own may explain why courts have occasionally swerved from one pole to another and why even the most experienced judges have committed fundamental errors in these cases. The testimony of an expert upon such issues, especially his cross-examination, greatly extends the trial and contributes nothing which cannot be better heard after the evidence is all submitted. It ought not to be allowed at all; and while its admission is not a ground for reversal, it cumbers the case and tends to confusion, for the more the court is led into the intricacies of dramatic craftsmanship, the less likely it is to stand upon the firmer, if more naive, ground of its considered impressions upon its own perusal. We hope that in this class of cases such evidence may in the future be entirely excluded, and the case confined to the actual issues; that is, whether the defendant copied it, so far as the supposed infringement is identical.

Riffled Independence for Efficient Inference with Partial Rankings

description: Distributions over rankings are used to model data in a multitude of real world settings such as preference analysis and political elections. Modeling such distributions presents several computational challenges, however, due to the factorial size of the set of rankings over an item set. Some of these challenges are quite familiar to the artificial intelligence community, such as how to compactly represent a distribution over a combinatorially large space, and how to efficiently perform probabilistic inference with these representations. With respect to ranking, however, there is the additional challenge of what we refer to as human task complexity users are rarely willing to provide a full ranking over a long list of candidates, instead often preferring to provide partial ranking information. Simultaneously addressing all of these challenges i.e., designing a compactly representable model which is amenable to efficient inference and can be learned using partial ranking data is a difficult task, but is necessary if we would like to scale to problems with nontrivial size. In this paper, we show that the recently proposed riffled independence assumptions cleanly and efficiently address each of the above challenges. In particular, we establish a tight mathematical connection between the concepts of riffled independence and of partial rankings. This correspondence not only allows us to then develop efficient and exact algorithms for performing inference tasks using riffled independence based represen- tations with partial rankings, but somewhat surprisingly, also shows that efficient inference is not possible for riffle independent models (in a certain sense) with observations which do not take the form of partial rankings. Finally, using our inference algorithm, we introduce the first method for learning riffled independence based models from partially ranked data.

description: Radio quasar sightlines with strong MgII absorption lines display statistically enhanced Faraday Rotation Measures (RM) indicating the presence of additional magneto-active plasma with respect to sightlines free of such absorption. In this letter, we use multi-color optical imaging to identify the likely galaxies hosting the magneto-active plasma, and to constrain the location of the latter with respect to the putative parent halo. We find that all of the sightlines with high |RM| pass within 50 kpc of a galaxy and that the |RM| distribution for low impact parameters, D < 50 kpc, is significantly different than for larger impact parameters. In addition, we find a decrease in the ratio of the polarization at 21 cm and 1.5 cm, p_{21}/p_{1.5}, towards lower D. These two effects are most likely related, strengthen the association of excess |RM| with intervening galaxies, and suggest that intervening galaxies operate as inhomogeneous Faraday screens. These results are difficult to reconciliate with only a disk model for the magnetic field but are consistent with highly magnetized winds associated with MgII systems. We infer strong magnetic fields of a few tens of mikro Gauss, consistent with values required by the lack of evolution of the FIR-radio correlation at high redshifts. Finally, these findings lends support to the idea that the small scale helicity bottleneck of alpha-Omega galactic dynamos can be significantly alleviated via galatic winds.

description: In 1989, Joe Simon-Whelan, an intimate of Andy Warhol, purchased one of the artist’s silk-screened self portraits for $195,000. Fred Hughes, the chairman of the Andy Warhol Foundation for the Visual Arts, signed an authentication of the portrait, certifying that it was genuine. In 2001, Simon Whelan’s investment appeared prescient: a buyer was prepared to part with $2,000,000 in exchange for the painting. However, members of the Andy Warhol Art Authentication Board, an entity created eight years after the Foundation, encouraged the buyer not to purchase the portrait until the Board had authenticated it. After Simon-Whelan eventually submitted the painting to the Board, the Board denied that Andy Warhol had authored the artwork. The Board invited Simon Whelan to resubmit his silk-screen with additional documentation; Simon-Whelan did, and the board denied the portrait’s authenticity a second time.

description: We present a model for aggregation of product review snippets by joint aspect identification and sentiment analysis. Our model simultaneously identifies an underlying set of ratable aspects presented in the reviews of a product (e.g., sushi and miso for a Japanese restaurant) and determines the corresponding sentiment of each aspect. This approach directly enables discovery of highly-rated or inconsistent aspects of a product. Our generative model admits an efficient variational mean-field inference algorithm. It is also easily extensible, and we describe several modifications and their effects on model structure and inference. We test our model on two tasks, joint aspect identification and sentiment analysis on a set of Yelp reviews and aspect identification alone on a set of medical summaries. We evaluate the performance of the model on aspect identification, sentiment analysis, and per-word labeling accuracy. We demonstrate that our model outperforms applicable baselines by a considerable margin, yielding up to 32% relative error reduction on aspect identification and up to 20% relative error reduction on sentiment analysis.

description: Anomaly detection is being regarded as an unsupervised learning task as anomalies stem from adversarial or unlikely events with unknown distributions. However, the predictive performance of purely unsupervised anomaly detection often fails to match the required detection rates in many tasks and there exists a need for labeled data to guide the model generation. Our first contribution shows that classical semi-supervised approaches, originating from a supervised classifier, are inappropriate and hardly detect new and unknown anomalies. We argue that semi-supervised anomaly detection needs to ground on the unsupervised learning paradigm and devise a novel algorithm that meets this requirement. Although being intrinsically non-convex, we further show that the optimization problem has a convex equivalent under relatively mild assumptions. Additionally, we propose an active learning strategy to automatically filter candidates for labeling. In an empirical study on network intrusion detection data, we observe that the proposed learning methodology requires much less labeled data than the state-of-the-art, while achieving higher detection accuracies.

description: Our aim was to identify gravitational lens candidates among some 5500 optical counterparts of the X-ray point-like sources in the medium-deep ~11 sq. deg. XMM-LSS survey. We have visually inspected the optical counterparts of each QSOs/AGN using CFHTLS T006 images. We have selected compact pairs and groups of sources which could be multiply imaged QSO/AGN. We have measured the colors and characterized the morphological types of the selected sources using the multiple PSF fitting technique. We found three good gravitational lens candidates: J021511.4-034306, J022234.3-031616 and J022607.0-040301 which consist of pairs of point-like sources having similar colors. On the basis of a color-color diagram and X-ray properties we could verify that all these sources are good QSO/AGN candidates rather than stars. Additional secondary gravitational lens candidates are also reported.

description: Over the last decade, the problem of orphan works—i.e., copyrighted works whose owners cannot be located by a reasonably diligent search—has come sharply into focus as libraries, archives and other large repositories of copyrighted works have sought to digitize and make available their collections online. Combined with new technology that has changed the way that copyrighted works are created and the way that consumers expect to access and use copyrighted works, the orphan works problem has grown into a significant and, as former Register of Copyrights Marybeth Peters observed, a “pervasive” problem. Although this problem is certainly not limited to digital libraries, it has proven especially challenging for these organizations because they hold diverse collections that include millions of books, articles, letters, photographs, home movies, films and other types of works. Many items come with a complex, unknown and often unknowable history of copyright ownership. Because U.S. copyright law provides for both strong injunctive relief and monetary damages (in the form of statutory damages of up to $150,000 per work infringed), organizations that cannot obtain permission often do not make their collections available at all. Large projects, such as Google Book Search and the HathiTrust digital library, which aim in part to address orphan works on a larger scale, have been drawn into litigation.

description: System Vicarious Calibration (SVC) ensures a relative radiometric calibration to satellite ocean color sensors that minimizes uncertainties in thewater-leaving radiance Lw derived fromthe top of atmosphere radiance LT. This is achieved through the application of gain-factors, g-factors, to pre-launch absolute radiometric calibration coefficients of the satellite sensor corrected for temporal changes in radiometric sensitivity. The g-factors are determined by the ratio of simulated to measured spectral LT values where the former are computed using: i. highly accurate in situ Lw reference measurements; and ii. the same atmospheric models and algorithms applied for the atmospheric correction of satellite data. By analyzing basic relations between relative uncertainties of Lw and LT, and g-factors consistently determined for the same satellite mission using different in situ data sources, this work suggests that the creation of ocean color Climate Data Records (CDRs) should ideally rely on: i. one main long-term in situ calibration system (site and radiometry) established and sustained with the objective to maximize accuracy and precision over time of g-factors and thus minimize possible biases among satellite data products from differentmissions; and additionally ii. unique (i.e., standardized) atmosphericmodel and algorithms for atmospheric correction to maximize cross-mission consistency of data products at locations different from that supporting SVC. Finally, accounting for results from the study and elements already provided in literature, requirements and recommendations for SVC sites and field radiometric measurements are streamlined

description: An interesting approach to the cosmological coincidence problem is to allow dark matter and dark energy interact with each other also nongravitationally. We consider two general Ansätze for such an interaction and appraise their ability to address the coincidence problem. We determine the average accuracy required on the cosmic expansion rate data to distinguish interacting cosmological models from the conventional $Λ$CDM scenario. We find that among the planned surveys the Wide Field Infrared Survey Telescope has the best chance to detect an interaction, though at a low significance level. To unambiguously determine the existence of an interaction one must, therefore, combine the said expansion data with other probes.

Post-Merger Bundling in the Cable Industry: The Case of Time Warner and Turner Broadcasting

description: "The cable industry consists of both upstream and downstream ﬁrms: the Cable Television Programming Service Providers (CTPSPs) and the Multichannel Service Operators (MSOs). The CTPSPs create and provide basic cable programming to MSOs in exchange for monthly per-subscriber fees; they also receive funding from advertisers (JRANK Encyclopedia).MSOs purchase franchise rights to operate in speciﬁc regions, where they act as monopoly providers of cable, providing subscribers with their choice of programming bundle for a monthly fee. In this paper, I look at the eﬀects upstream bundling may have on subscribers. Gregory Crawford shows that downstream bundling of highly sought-after programming lowers subscriber surplus but raises proﬁts for the cable providers (Crawford 2006). However, a model allowing for diﬀerentiated consumer preferences reveals that the price-discriminatory effects of bundling while Michael Whinston emphasizes that bundling independent goods is an eﬀective and proﬁtable means for deterring entry (Whinston 1990), my model points to a somewhat counterintuitive outcome: product bundling can, at times, facilitate market entry by competitors and improve the welfare of consumers. My approach supports MSOs purchase franchise rights to operate in may in fact raise consumer surplus. Indeed, previous research conducted by Whinston that models heterogeneous preferences for one monopoly good that is tied to another monopoly good in a market that faces entry. My contribution is an evaluation of the eﬀect of bundling on entry deterrence in light of heterogeneous preferences for both goods. My model also applies the theoretical aspects of bundling to a speciﬁc case in the cable industry; the Time Warner-Turner merger ﬁnalized in September of 1996 et al., Complaint, 1997) serves as both an illustration and inspiration for my model.."--from page 198-199

Understanding tetrahedral liquids through patchy colloids

description: We investigate the structural properties of a simple model for tetrahedral patchy colloids in which the patch width and the patch range can be tuned independently. For wide bond angles, a fully bonded network can be generated by standard Monte Carlo or molecular dynamics simulations of the model, providing a neat method for generating defect-free random tetrahedral networks. This offers the possibility of focusing on the role of the patch angular width on the structure of the fully bonded network. The analysis of the fully bonded configurations as a function of the bonding angle shows how the bonding angle controls the system compressibility, the strength of the pre-peak in the structure factor and ring size distribution. Comparison with models of liquid water and silica allows us to find the best mapping between these continuous potentials and the colloidal one. Building on previous studies focused on the connection between angular range and crystallization, the mapping makes it possible to shed new light on the glass-forming ability of network-forming tetrahedral liquids.

description: Nonacademic student supports are activities and programs that are designed to encourage academic success but that do not deal directly with academic content. They include formally structured programs—such as student success courses—and one-on-one services, such as academic, career, and financial aid advising. Some nonacademic student supports are provided in an academic context through activities such as required study groups, mandatory meetings with professors, and faculty/ staff interactions with students.
