description: In the singlet Majoron model, we study cosmological phase transitions (PTs) and their resulting gravitational waves (GWs), in the two-field phase space, without freezing any of the field directions. We first calculate the effective potential, at one loop and at finite temperature, of the Standard Model Higgs doublet together with one extra Higgs singlet. We make use of the public available Python package CosmoTransitions to simulate the two-dimensional cosmological PTs and evaluate the gravitational waves generated by first-order PTs. With the full 2D simulation, we are able not only to confirm the PTs' properties previously discussed in the literature, but also we find new patterns, such as strong first-order PTs tunneling from a vacuum located on one axis to another vacuum located on the second axis. The two-field phase space analysis presents a richer panel of cosmological PT patterns compared to analysis with a single-field approximation. The PTGW amplitudes turn out to be out of the reach for the space-borne gravitational wave interferometers such as LISA, DECIGO, BBO, TAIJI and TianQin when constraints from colliders physics are taken into account.

description: Anthropology attempts to make other groups intelligible to a secular, humanistic academic audience. To a person without faith, who does not accept religious dogma, the rituals of other communities can seem arbitrary and without significance. Investigating the anthropology of religion, based on the perspective of Clifford Geertz (1973), I have found a language and body of literature that makes the rituals I’ve witnessed in India and Brazil intelligible. I will argue that ritual creates a cosmic framework for Catholic and Hindu communities, which corresponds to their personal experience. Religion gives meaning to people’s bodies, impulses, and social roles by incorporating individual experience into eternal time. I believe that the sacrifices individuals’ make for communal stability serves a similar function to sacrifices for Gods. Pollution or sin can be understood as estranging the individual from the social group. The separation between the physical world and the social world is most evident when an individual dies. Mortuary customs are the strongest case of humans trying to impose their agency on the cosmos. Through the investigation of mortuary customs the symbolic worlds of religion become intelligible to a secular humanist.

description: Two of the most attractive spectral windows for spectropolarimetric investigations of the physical properties of the plasma structures in the solar chromosphere and corona are the ones provided by the spectral lines of the He I 10830 A and 5876 A (or D3) multiplets, whose polarization signals are sensitive to the Hanle and Zeeman effects. However, in order to be able to carry out reliable diagnostics, it is crucial to have a good physical understanding of the sensitivity of the observed spectral line radiation to the various competing driving mechanisms. Here we report a series of off-the-limb non-LTE calculations of the He I D3 and 10830 A emission profiles, focusing our investigation on their sensitivity to the EUV coronal irradiation and the model atmosphere used in the calculations. We show in particular that the intensity ratio of the blue to the red components in the emission profiles of the He I 10830 A multiplet turns out to be a good candidate as a diagnostic tool for the coronal irradiance. Measurements of this observable as a function of the distance to the limb and its confrontation with radiative transfer modeling might give us valuable information on the physical properties of the solar atmosphere and on the amount of EUV radiation at relevant wavelengths penetrating the chromosphere from above.

description: Two quasi-linear approximations, the frozen flow approximation (FFA) and the frozen potential approximation (FPA), have been proposed recently for studying the evolution of a collisionless self-gravitating fluid. In the FFA it is assumed that the velocity field remains unchanged from its value obtained from the linear theory whereas in FPA the same approximation is made for the gravitational potential. In this paper we compare these and the older Zel'dovich approximation by calculating the evolution of the density in perturbation theory. In particular we compute the skewness, including the smoothing effects, and the kurtosis for the FFA, FPA and Zel'dovich approximation and compare their relative accuracy.

description: Generation of magnetic field during inflation can explain its presence over a wide range of scales in the Universe. In Ref.\cite{sharma2017}, we proposed a model to generate these fields during inflation. These fields have nonzero anisotropic stress which lead to the generation of a stochastic background of gravitational waves (GW) in the early universe. Here we show that for a scenario of magnetogenesis where reheating takes place around QCD epoch, this stochastic GW background lies in the $95\%$ confidence region of the GW signal probed by NANOGrav collaboration. This is the case when the generated electromagnetic field (EM) energy density is $3-10\%$ of the background energy density at the end of reheating. For this case, the values of magnetic field strength $B_0 \sim (3.8-6.9) \times 10^{-11}$G and its coherence length $\sim 30$ kpc at the present epoch. These values are for the models in which EM fields are of nonhelical nature. For the helical nature of the fields, these values are $B_0 \sim (1.1-1.9) \times 10^{-9}$G and its coherence length $\sim 0.8$ Mpc.

description: We present an analysis of XMM-Newton observations of the superbubble 30 Dor C and compare the results with the predictions from the standard wind-blown bubble model. We find that the observed X-ray spectra cannot be fitted satisfactorily with the model alone and that there is evidence for nonthermal X-ray emission, which is particularly important at 4 keV. The combination of the bubble model and a power law gives a reasonable fit to the observed spectra. The thermal pressure and central temperature of the bubble are 3.3 × 10-11 dynes cm-2 and 7.4 × 106 K, respectively, and we infer that for a bubble age of t ~ 4 × 106 yr the ambient density is n0 38 cm-3, the mechanical luminosity is Lmech ~ 1037 ergs s-1, and the coefficient of thermal conductivity is ~0.05 of the Spitzer value. The total unabsorbed 0.1-10 keV luminosities of the eastern and western parts of the bubble are 3 × 1036 and 5 × 1036 ergs s-1, respectively. The unabsorbed 0.1-10 keV luminosity of the bubble model is ~4 × 1036 ergs s-1, and so the power-law component contributes between and of the total unabsorbed luminosity in this energy band. The nature of the hard nonthermal emission is not clear, although recent supernovae in the bubble may be responsible. We expect that about one or two core-collapse supernovae could have occurred and are required to explain the enrichment of the hot gas, as evidenced by the overabundance of α-elements by a factor of 3, compared to the mean value of ~0.5 solar for the interstellar medium in the Large Magellanic Cloud. As in previous studies of various superbubbles, the amount of energy currently present in 30 Dor C is significantly less than the expected energy input from the enclosed massive stars over their lifetime. We speculate that a substantial fraction of the input energy may be radiated in the far-infrared by dust grains, which are mixed with the hot gas because of the thermal conduction and/or dynamic mixing.
Religion, discrimination and assimilation: a comparison of contemporary France and the United States
Creators: name: Ali, Huma
Publisher: name: Carnegie Mellon University
Year: 2012
Subjects: History

description: France and the United States are both secular Western countries that are founded upon similar Enlightenment ideals. By virtue of these similarities, one might expect these countries to have similar relationships between church and state. In actuality, however, the secularism that France and the United States both value is a very loosely defined concept whose interpretation and application can widely vary. Specifically, these countries sharply differ in how they interpret the principle of segregation of church and state, how they organize religious diversity, and how the state treats it. Each of these countries’ relationships with religion profoundly affects the assimilation of a minority group. France interprets its secularism as a stark relegation of religion to the private sphere, and in passing the recent headscarves ban, has introduced barriers for the nation’s Muslim subpopulation. Meanwhile, the United States’ culture of religiosity allows for private matters, such as sexual orientation, to become a public concern, as is the case in the ongoing debate surrounding same-sex marriage. While both countries’ debates discuss religion’s role with respect to the preservation of national integrity, France and the United States should instead recognize that they are actually depriving these minorities of a sense of national belonging and work to encourage further civic assimilation.

description: The samples LaCoO3 with dilute substitutions on cobalt sites have been studied using the resistivity, thermopower and magnetic susceptibility measurements over the temperature range up to ~900 K. The Co-site substitution does not affect the magnetic transition at ~100 K and the onset of massive population of hole carriers at ~500 K, characteristic for undoped LaCoO3. On the other hand, the low-temperature transport and magnetism is markedly distinct for samples with extra charge on cobalt ions introduced by the heterovalent dopants (Mg2+, Ti4+) compared to samples with minor non-stoichiometry (LaCoO3, Ga3+ doped sample). Magnetic properties suggest that these extra charges create thermally stable magnetic polarons of total S ~ 2-3. Common features of Co-site doped and La-site doped samples (La1-xSrxCoO3) are discussed

description: The statistical cosmological principle states that observables on the celestial sphere are sampled from a rotationally invariant distribution. Previously certain large scale anomalies which violate this principle have been found, for example an alignment of the lowest multipoles with the cosmic dipole direction. In this work we continue the search for possible anomalies using multipole vectors which represent a convenient tool for this purpose. In order to study the statistical behavior of multipole vectors, we revisit several construction methods. We investigate all four full-sky foreground-cleaned maps from the Planck 2015 release with respect to four meaningful physical directions using computationally cheap statistics that have a simple geometric interpretation. We find that the full-sky SEVEM map deviates from all the other cleaned maps, as it shows a strong correlation with the Galactic Pole and Galactic Center. The other three maps COMMANDER, NILC and SMICA show a consistent behavior. On the largest angular scales, $l \leq 5$, as well as on intermediate scales, $l = 20, 21, 22, 23, 24$, all of them are unusually correlated with the cosmic dipole direction. These scales coincide with the scales on which the angular power spectrum deviates from the Planck 2015 best-fit ΛCDM model. In the range $2 \leq l \leq 50$ as a whole there is no unusual behavior visible globally. We do not find abnormal intramultipole correlation, i.e. correlation of multipole vectors inside a given multipole without reference to any outer direction.

description: Current screen reader technology presents the content of web pages to users as a one-dimensional stream of data. However, as web pages themselves are two-dimensional, we believe this output method is lossy since it removes the visuospatial relationships between elements. Keyboard surface interaction is a growing field within human computer interaction that studies the repurposing of keyboards for nontraditional applications. We compare a keyboard surface interaction system (Fingers) designed to preserve the visuospatial relationships between web page elements to a traditional screen reader (VoiceOver) to learn which has better interaction effectiveness measured in terms of time spent and interactions per task on four simulated shopping tasks. We find no consistent difference in effectiveness between the two conditions. Participants consistently have more interactions per task with Fingers than with VoiceOver, but it is unclear whether this positively or negatively impacts their time. We find that learning a new mental model of a keyboard is challenging for participants. We suggest further research into the applicability of keyboard surface interaction as an alternative form of web accessibility, but that future studies take a longitudinal nature to help participants learn the mental model required and overcome the novelty effect.

description: Since the 1970's, physicists and mathematicians who study random matrices in the GUE or GOE models are aware of intriguing connections between integrals of such random matrices and enumeration of graphs on surfaces. We establish a new aspect of this theory: for random matrices sampled from the group $\mathcal{U}\left(n\right)$ of unitary matrices. More concretely, we study measures induced by free words on $\mathcal{U}\left(n\right)$. Let $F_{r}$ be the free group on $r$ generators. To sample a random element from $\mathcal{U}\left(n\right)$ according to the measure induced by $w\in F_{r}$, one substitutes the $r$ letters in $w$ by $r$ independent, Haar-random elements from $\mathcal{U}\left(n\right)$. The main theme of this paper is that every moment of this measure is determined by families of pairs $\left(Σ,f\right)$, where $Σ$ is an orientable surface with boundary, and $f$ is a map from $Σ$ to the bouquet of $r$ circles, which sends the boundary components of $Σ$ to powers of $w$. A crucial role is then played by Euler characteristics of subgroups of the mapping class group of $Σ$. As corollaries, we obtain asymptotic bounds on the moments, we show that the measure on $\mathcal{U}\left(n\right)$ bears information about the number of solutions to the equation $\left[u_{1},v_{1}\right]\cdots\left[u_{g},v_{g}\right]=w$ in the free group, and deduce that one can ``hear'' the stable commutator length of a word through its unitary word measures.

description: Excitons in a semiconductor monolayer form a collective resonance that can reflect resonant light with extraordinarily high efficiency. Here, we investigate the nonlinear optical properties of such atomistically thin mirrors and show that finite-range interactions between excitons can lead to the generation of highly non-classical light. We describe two scenarios, in which optical nonlinearities arise either from direct photon coupling to excitons in excited Rydberg states or from resonant two-photon excitation of Rydberg excitons with finite-range interactions. The latter case yields conditions of electromagnetically induced transparency and thereby provides an efficient mechanism for single-photon switching between high transmission and reflectance of the monolayer, with a tunable dynamical timescale of the emerging photon-photon interactions. Remarkably, it turns out that the resulting high degree of photon correlations remains virtually unaffected by Rydberg-state decoherence, in excess of non-radiative decoherence observed for ground-state excitons in two-dimensional semiconductors. This robustness to imperfections suggests a promising new approach to quantum photonics at the level of individual photons.

description: We demonstrate experimentally that the introduction of a rail, a small height constriction, within the cross-section of a rectangular channel could be used as a robust passive sorting device in two-phase fluid flows. Single air bubbles carried within silicone oil are generally transported on one side of the rail. However, for flow rates marginally larger than a critical value, a narrow band of bubble sizes can propagate (stably) over the rail, while bubbles of other sizes segregate to the side of the rail. The width of this band of bubble sizes increases with flow rate and the size of the most stable bubble can be tuned by varying the rail width. We present a complementary theoretical analysis based on a depth-averaged theory, which is in qualitative agreement with the experiments. The theoretical study reveals that the mechanism relies on a non-trivial interaction between capillary and viscous forces that is fully dynamic, rather than being a simple modification of capillary static solutions.

In the method we perform the two-dimensional Haar wavelet transform of configuration of Fortuin-Kasteleyn (FK) clusters. The configuration represents a direct snapshot of spin-spin correlations since spin degrees of freedom are traced out in FK representation. A snapshot of FK clusters loses image information at each coarse-graining process by the wavelet transform. We show that the loss of image information measures the entanglement entropy in the Potts model.

description: The 1970s and 1980s witnessed the birth, development, and subsequent multiplication of congressional caucuses, which have adapted and evolved over several decades into powerful, unofficial, congressional institutions. Despite their importance to the broader congressional system, caucuses have received little scholarly attention. Author Susan Webb Hammond published the most thorough and substantive study to date, entitled Congressional Caucuses in National Policymaking (1998). According to Hammond, the traditional congressional structure was unable to respond effectively to the “changes in the polity” that arose during this time period, leading to the emergence of congressional caucuses. The central change came when “an increasing number of complex, crosscutting, and interconnected issues began to occupy the congressional agenda.” Hammond provides the example of the environment as a growing topic of national attention that simultaneously raised concerns for health, economics, and several other intersecting areas. Congress grew increasingly ineffective in handling these issues that began falling “into jurisdictional cracks” or were dispersed across several committees and subcommittees.

description: A recently published report has called into question the validity of the equivalence theorem in dynamically broken gauge theories in which the fermions making up the symmetry breaking condensate lie in an anomalous representation of the broken gauge group. Such a situation can occur if the gauge anomaly is cancelled by another sector of the theory. Using the example of the one family Standard Model without scalar Higgs structure, we analyze a low energy effective theory which preserves the symmetries of the fundamental theory and demonstrate the validity of the equivalence theorem in this class of models.

description: Overdoped high-temperature cuprate superconductors have been widely believed to be described by the physics of d-wave BCS-like superconductivity. However, recent measurements indicate that as the doping is increased, the superfluid density decreases smoothly to zero rather than increasing as expected by BCS theory in the absence of disorder. Here, we combine time-domain THz spectroscopy with kHz range mutual inductance measurements on the same overdoped La$_{2-x}$Sr$_{x}$CuO$_{4}$ films to determine both the superfluid and the uncondensed carrier density as a function of doping. A significant fraction of the carriers remains uncondensed in a wide Drude-like peak even as $T\rightarrow0$, which, when taken with the linear-in-temperature superfluid density, is inconsistent with existing theories for the role of disorder in suppressing the superfluid density in a d-wave superconductor. Our almost eight orders of magnitude in measurement frequency range gives us a unique look at the low frequency spectral weight distribution, which may suggest the presence of quantum phase fluctuations as the critical doping is approached.

description: The process of pairing words with their referents in the real world is often ambiguous; the same word may refer to different objects, the same object may be referred to by different words, and there may just be insufficient environmental cues to assist us in the process. Thus, how is it that adults are able to go about this, particularly when the word-referent pairings are not constant? Three different experiments were completed which tested the ability of adults to pair up novel words and shapes after being exposed to a learning phase where the words referred to the correct object either 50% or 75% of the time, in order to simulate the ambiguity of real-world referents and determine to what extent that ambiguity impairs their ability to correctly match them. The results showed that although all adults were able to determine word boundaries within the stream of speech, the difference in ability between the two conditions on pairing the words with their referents was not significantly different

From the absorption spectrum we extract the excitation energy of the CDW gap and estimate the fraction of the Fermi surface which is gapped by the formation of the CDW condensate. In analogy to previous findings on the related $R$Te$_n$ (n=2 and 3) families, we establish the progressive closing of the CDW gap and the moderate enhancement of the metallic component upon chemically compressing the lattice.

description: Weak lensing peak counts are a powerful statistical tool for constraining cosmological parameters. So far, this method has been applied only to surveys with relatively small areas, up to several hundred square degrees. As future surveys will provide weak lensing datasets with size of thousands of square degrees, the demand on the theoretical prediction of the peak statistics will become heightened. In particular, large simulations of increased cosmological volume are required. In this work, we investigate the possibility of using simulations generated with the fast Comoving-Lagrangian acceleration (COLA) method, coupled to the convergence map generator Ufalcon, for predicting the peak counts. We examine the systematics introduced by the COLA method by comparing it with a full TreePM code. We find that for a 2000 deg$^2$ survey, the systematic error is much smaller than the statistical error. This suggests that the COLA method is able to generate promising theoretical predictions for weak lensing peaks. We also examine the constraining power of various configurations of data vectors, exploring the influence of splitting the sample into tomographic bins and combining different smoothing scales. We find the combination of smoothing scales to have the most constraining power, improving the constraints on the $S_8$ amplitude parameter by at least 40% compared to a single smoothing scale, with tomography brining only limited increase in measurement precision.

description: Recently 't Hooft demonstrated that ``For any quantum system there exists at least one deterministic model that reproduces all its dynamics after prequantization''. An extension is presented here which covers quantum systems that are characterized by a complete set of mutually commuting Hermitian operators (``beables''). We introduce the symmetry of beables: any complete set of beables is as good as any other one which is obtained through a real general linear group transformation. The quantum numbers of a specific set are related to symmetry breaking initial and boundary conditions in a deterministic model. The Hamiltonian, in particular, can be taken as the emergent beable which provides the best resolution of the evolution of the model universe.

description: The normal and pairing self-energies are the microscopic quantities which reflect and characterize the underlying interaction in superconductors. The momentum and frequency dependence of the self-energies, therefore, provides the experimental criteria which can single out the long sought-after pairing interaction among many proposed ideas. This line of research to pin down the pairing interaction for the cuprate superconductors has been carried out with some success by analyzing the momentum distribution curves of laser angle-resolved photo-emission spectroscopy (ARPES) data. Some progress and results are presented and compared with theoretical calculations based on leading proposals. Comments are made on the proposed scenarios from the comparisons.

description: The effect of applying an external electric field on doping-induced spin-orbit splitting of the lowest conduction-band states in a bismuth-doped zinc oxide nanowire is studied by performing electronic structure calculations within the framework of density functional theory. It is demonstrated that spin splitting in Bi-doped ZnO nanowires could be tuned and enhanced electrically via control of the strength and direction of the applied electric field, thanks to the nonuniform and anisotropic response of the ZnO:Bi nanowire to external electric fields. The results reported here indicate that a single ZnO nanowire doped with a low concentration of Bi could function as a spintronic device, operation of which is controlled by applied lateral electric fields.

description: I will first give a brief introduction of queer theory development in the United States during the 1990s. Then, I will discuss the applicability, merits, and uncertainties of using ‘western’ queer theory as a way to understand China’s tongzhi (a now-mainstream term for Chinese gays and lesbians) culture within a domestic and international context. There is a widestretching spectrum of arguments regarding the universalism and anti-universalism of queer theory, and the conceivably colonialist connotations of this application to non-Western societies; I make an appeal for a universalist application of queer theory that places Chinese tongzhis as unique queer global citizens, and members of a not-necessarily imperialistic movement.

description: We investigate the stellar populations for a sample of 161 massive, mainly quiescent galaxies at $\langle z_{\rm obs} \rangle=0.8$ with deep Keck/DEIMOS rest-frame optical spectroscopy (HALO7D survey). With the fully Bayesian framework Prospector, we simultaneously fit the spectroscopic and photometric data with an advanced physical model (including non-parametric star-formation histories, emission lines, variable dust attenuation law, and dust and AGN emission) together with an uncertainty and outlier model. We show that both spectroscopy and photometry are needed to break the dust-age-metallicity degeneracy. We find a large diversity of star-formation histories: although the most massive ($M_{\star}>2\times10^{11}~M_{\odot}$) galaxies formed the earliest (formation redshift of $z_{\rm f}\approx5-10$ with a short star-formation timescale of $τ_{\rm SF}\lesssim1~\mathrm{Gyr}$), lower-mass galaxies have a wide range of formation redshifts, leading to only a weak trend of $z_{\rm f}$ with $M_{\star}$. Interestingly, several low-mass galaxies with have formation redshifts of $z_{\rm f}\approx5-8$. Star-forming galaxies evolve about the star-forming main sequence, crossing the ridgeline several times in their past. Quiescent galaxies show a wide range and continuous distribution of quenching timescales ($τ_{\rm quench}\approx0-5~\mathrm{Gyr}$) with a median of $\langleτ_{\rm quench}\rangle=1.0_{-0.9}^{+0.8}~\mathrm{Gyr}$ and of quenching epochs of $z_{\rm quench}\approx0.8-5.0$ ($\langle z_{\rm quench}\rangle=1.3_{-0.4}^{+0.7}$). This large diversity of quenching timescales and epochs points toward a combination of internal and external quenching mechanisms. In our sample, rejuvenation and "late bloomers" are uncommon. In summary, our analysis supports the "grow & quench" framework and is consistent with a wide and continuously-populated diversity of quenching timescales.

description: The wider stress literature points to negative associations between stress and well-being. Similarly, the use of engagement coping strategies and disengagement coping strategies in the face of stress are related to improved and reduced well-being respectively. However, in the autistic population stress and coping research is limited to date, and the extent to which coping may moderate the relationship between stress and well-being is not known. Using data from an Australian online study, we explored the potential moderating (i.e. buffering or exacerbating) role of coping in the relationship between stress and well-being in a sample of autistic adults (N = 86). Our findings indicated that increased stress was associated with lower well-being. Further, moderation analyses showed that while both engagement coping (e.g. problem solving, positive appraisal) and disengagement coping (e.g., self-distraction, being in denial) strategies had significant positive and negative direct effects on well-being respectively; engagement coping also moderated the relationship between stress and well-being, buffering the impact of stress on well-being. Our results illustrate the different underlying mechanisms by which coping strategies may be associated with stress and well-being. They also highlight the potential protective role of engagement coping strategies, which can be incorporated into the promotion and maintenance of well-being in autistic adults.

description: This collection is focused on exploring poetry’s role as both a question and an answer. In many ways poetry can embody both the quest for truth and the truth itself. Poetry has the power to articulate many subtle truths while in the end raising just as many questions as it answers. The act of writing a poem is an act of asking. The act of writing a poem is an act of seeking. When writing a poem, the poet embarks on a journey: a journey to the past, to the interior self, to faraway lands and alien spaces. The poet records these journeys like an adventurer keeping a log, and presents these findings on paper. A poem is an artifact, brought back from these journeys. Because the poem is presented as a result of these searchings, we could conclude that it is an answer, a conclusion to the journey, a satisfactory ending. But more often than not, the artifact raises just as many questions as it answers. The poet turns it over in her hands, discovering observations previously unnoticed. The poet is drawn into journeying back into these spaces, creating an endless cycle of questions and answers. I conducted the Q & A project over the span of nine months. The poems contained in this collection were written as responses to actual questions posted on the online site ‘Yahoo Answers’. On this site, anyone can post questions for the rest of the community to answer. They can do so anonymously, or create a public profile. Points are awarded to those who attempt to answer questions, in order to encourage participation. The title of ‘Best Answer’ is awarded to each resolved question by the questioner, or voted on by the community.
