Causality constraints in AdS/CFT from conformal collider physics and Gauss-Bonnet gravity

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

description: We explore the relation between positivity of the energy constraints in conformal field theories and causality in their dual gravity description. Our discussion involves CFTs with different central charges whose description, in the gravity side, requires the inclusion of quadratic curvature corrections. It is enough, indeed, to consider the Gauss-Bonnet term. We find that both sides of the AdS/CFT correspondence impose a restriction on the Gauss-Bonnet coupling. In the case of 6d supersymmetric CFTs, we show the full matching of these restrictions. We perform this computation in two ways. First by considering a thermal setup in a black hole background. Second by scrutinizing the scattering of gravitons with a shock wave in AdS. The different helicities provide the corresponding lower and upper bounds. We generalize these results to arbitrary higher dimensions and comment on some hints and puzzles they prompt regarding the possible existence of higher dimensional CFTs and the extent to which the AdS/CFT correspondence would be valid for them.

Geology and mineralisation of the Cape Horn - Lyell Comstock area, Mt Lyell
Creators: name: Green, GR

description: Stratigraphically the disseminated chalcopyrite-pyrite ores of Cape Horn occur in ignimbrites (?) whereas altered lithic tuffs higher in the sequence of the Mt. Read Volcanics are the host rocks for the chalcopyrite-pyrite-bornite mineralization of Lyell Comstock. Chalcopyrite-sphalerite-galena-deposits in replacement (?) chert provide a mineralogical transition between the copper ores and the banded exhalative pyrite-galena-sphalerite lenses of the Tasman Shaft. On the basis of ore and gangue mineralogy and texture correlations are tentatively proposed between the West Lyell and Cape Horn, and between the Lyell Comstock and North Lyell-Crown Lyell deposits. This stratigraphic correlation is in sympathy with the distribution of trace elements in' the sulphides. Geochemical studies indicate that at least some of the Cape Horn ore represents an addition to, rather than a replacement of, the host rock. Copper mineralization occurs in areas of sericitization and silicification locally representing the most intense facies of alteration. Clastic sediments overlying the ores contain feldspars in all stages of alteration and detrital sulphides. These are interbedded with Middle Cambrian limestones, providing the most convincing evidence to date of the age of the hydrothermal alteration and sulphide deposition.

description: The first equation was used to use the mg of protein per g of dry weight (DW) to estimate the DW percentage of protein of different studies on Pistia stratiotes. When only the fresh weight (FW) of P. stratiotes was reported, the protein value in dry weight was estimated. Since P. stratiotes has a 93.81% of average water content, the second formula allowed to calculate the dry weight protein content from a fresh weight protein.

description: Background: Exposure to environmental toxicants is associated with numerous disease outcomes, many of which involve underlying immune and inflammatory dysfunction. Objectives: To address the gap between environmental exposures and immune dysfunction, we investigated the association of two endocrine-disrupting compounds (EDCs) with markers of immune function. Methods: Using data from the 2003-2006 National Health and Nutrition Examination Survey, we compared urinary bisphenol A (BPA) and triclosan levels with serum cytomegalovirus (CMV) antibody levels and diagnosis of allergies or hay fever in U.S. adults and children ≥ 6 years of age. We used multivariate ordinary least squares linear regression models to examine the association of BPA and triclosan with CMV antibody titers, and multivariate logistic regression models to investigate the association of these chemicals with allergy or hay fever diagnosis. Statistical models were stratified by age (< 18 years and ≥ 18 years). Results: In analyses adjusted for age, sex, race, body mass index, creatinine levels, family income, and educational attainment, in the ≥ 18-year age group, higher urinary BPA levels were associated with higher CMV antibody titers (p < 0.001). In the < 18-year age group, lower levels of BPA were associated with higher CMV antibody titers (p < 0.05). However, triclosan, but not BPA, showed a positive association with allergy or hay fever diagnosis. In the < 18-year age group, higher levels of triclosan were associated with greater odds of having been diagnosed with allergies or hay fever (p < 0.01). Conclusions: EDCs such as BPA and triclosan may negatively affect human immune function as measured by CMV antibody levels and allergy or hay fever diagnosis, respectively, with differential consequences based on age. Additional studies should be done to investigate these findings.

description: As potential regulators of DNA accessibility and activity, epigenetic modifications offer a mechanism by which the environment can moderate the effects of genes. To date, however, there have been relatively few studies assessing epigenetic modifications associated with post-traumatic stress disorder (PTSD). Here we investigate PTSD-associated methylation differences in 33 genes previously shown to differ in whole blood-derived gene expression levels between those with vs. without the disorder. Drawing on DNA samples similarly obtained from whole blood in 100 individuals, 23 with and 77 without lifetime PTSD, we used methylation microarray data to assess whether these 33 candidate genes showed epigenetic signatures indicative of increased risk for, or resilience to, PTSD. Logistic regression analyses were performed to assess the main and interacting effects of candidate genes' methylation values and number of potentially traumatic events (PTEs), adjusting for age and other covariates. Results revealed that only one candidate gene-MAN2C1}-showed a significant methylation x PTE interaction, such that those with both higher MAN2C1 methylation and greater exposure to PTEs showed a marked increase in risk of lifetime PTSD (OR 4.35, 95% CI: 1.07, 17.77, p=0.04). These results indicate that MAN2C1 methylation levels modify cumulative traumatic burden on risk of PTSD, and suggest that both gene expression and epigenetic changes at specific loci are associated with this disorder.

description: Background: Cytomegalovirus (CMV) is a prevalent herpesvirus with links to both stress and aging. This paper describes and validates a minimally invasive method for assessing antibodies against CMV in finger stick whole blood spot samples for use as an indirect marker of an aspect of cell-mediated immunity.Results: Analysis of CMV in dried blood spot samples (DBS) was based on modifications of a commercially available protocol for quantifying CMV antibodies in serum or plasma. The method was evaluated through analysis of precision, reliability, linearity, and correlation between matched serum and DBS samples collected from 75 volunteers. Correlation between DBS and plasma values was linear and high (Pearson correlation R = .96), and precision, reliability, and linearity of the DBS assay were within acceptable ranges.Conclusions: The validity of a DBS assay for CMV antibodies will enable its inclusion in population-based surveys and other studies collecting DBS samples in non-clinical settings, increasing scientific understanding of the interaction of social and biological stress and immune function.

description: Magnetic impurities in neutral graphene provide a realization of the pseudogap Kondo model, which displays a quantum phase transition between phases with screened and unscreened impurity moment. Here, we present a detailed study of the pseudogap Kondo model with finite chemical potential mu. While carrier doping restores conventional Kondo screening at lowest energies, properties of the quantum critical fixed point turn out to influence the behavior over a large parameter range. Most importantly, the Kondo temperature T_K shows an extreme asymmetry between electron and hole doping. At criticality, depending on the sign of mu, T_K follows either the scaling prediction T_K ~ |mu| with a universal prefactor, or T_K ~ |mu|^x with x = 2.6. This asymmetry between electron and hole doping extends well outside the quantum critical regime and also implies a qualitative difference in the shape of the tunneling spectra for both signs of mu.

description: We introduce a method for estimating incidence curves of several co-circulating infectious pathogens, where each infection has its own probabilities of particular symptom profiles. Our deconvolution method utilizes weekly surveillance data on symptoms from a defined population as well as additional data on symptoms from a sample of virologically confirmed infectious episodes. We illustrate this method by numerical simulations and by using data from a survey conducted on the University of Michigan campus. Last, we describe the data needs to make such estimates accurate.

description: Background: Studies have suggested that CMV infection may influence cardiovascular disease (CVD) risk and mortality. However, there have been no large-scale examinations of these relationships among demographically diverse populations. The inflammatory marker C-reactive protein (CRP) is also linked with CVD outcomes and mortality and may play an important role in the pathway between CMV and mortality. We utilized a U.S. nationally representative study to examine whether CMV infection is associated with all-cause and CVD-related mortality. We also assessed whether CRP level mediated or modified these relationships. Methodology/Principal Findings: Data come from subjects ≥25 years of age who were tested for CMV and CRP level and were eligible for mortality follow-up on December 31st, 2006 (N = 14153) in the National Health and Nutrition Examination Survey (NHANES) III (1988-1994). Cox proportional hazard models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for all-cause and CVD-related mortality by CMV serostatus. After adjusting for multiple confounders, CMV seropositivity remained statistically significantly associated with all-cause mortality (HR 1.19, 95% CI: 1.01, 1.41). The association between CMV and CVD-related mortality did not achieve statistical significance after confounder adjustment. CRP did not mediate these associations. However, CMV seropositive individuals with high CRP levels showed a 30.1% higher risk for all-cause mortality and 29.5% higher risk for CVD-related mortality compared to CMV seropositive individuals with low CRP levels. Conclusions/Significance: CMV was associated with a significant increased risk for all-cause mortality and CMV seropositive subjects who also had high CRP levels were at substantially higher risk for both for all-cause and CVD-related mortality than subjects with low CRP levels. Future work should target the mechanisms by which CMV infection and low-level inflammation interact to yield significant impact on mortality.

description: We report the effect of adipic acid (C6H10O4) doping on lattice parameters, microstructure, critical temperature (Tc), current density (Jc), and irreversibility field (Hirr) for MgB2 superconductor. Actual carbon (C) substitution level for boron (B) is estimated to be from 0.40 percent to 2.95 percent for different doping levels. A reduction in Tc from 38.43 to 34.93 K and in lattice parameter a from 3.084(3) A to 3.075(6) Ais observed for the10 wt percent C6H10O4 doped sample in comparison to pristine MgB2. This is an indication of C substitution at boron sites, with the C coming from the decomposition of C6H10O4 at the time of reaction. Interestingly the doped samples have resulted in significant enhancement of Jc and Hirr. All the doped samples exhibit the Jc value of the order of 10^4 A/cm2 at 5 K and 8 T, which is higher by an order of magnitude as compared to undoped sample. This result indicates that C6H10O4 is a promising material for MgB2 for obtaining the excellent Jc values under higher magnetic fields.

Spiritual wellbeing and its relationship to adolescent resilience. A case study of Australian youth attending one local church.
Creators: name: Smith, Lindsay
Publisher: name: University Of Tasmania
Year: 2023

description: The purpose of this study was to examine the relationships and connections within the family and the local Christian church community influencing spiritual wellbeing of young people engaged with Christian spirituality. Questions have arisen recently about the role of spiritual wellbeing in strengthening resilience of youth. To explore this association, this research focused on the relationships and connectedness of people who attend one religious organisation as one means of enhancing their spiritual wellbeing. Two separate but complementary theories underpinned this research: the bioecological theory of human development (Bronfenbrenner 2001a) and the international family strengths model (DeFrain & Asay 2007a). In line with the purposes of an instrumental case study, different sources of data (quantitative and qualitative) were collected on the phenomenon of interest‚ÄövÑvÆspiritual wellbeing. Utilising a survey method, a theoretical purposive sample of sixty five people participated in this study. Through an abductive analysis process, the research identified a model of five spiritual strengths that enhance peace and life satisfaction and strengthen youth resilience within the lives of the young people in this study. Spiritual wellbeing and resilience were shown to be interrelated and ecologically bound. This case study presents one possible explanation for the often observed yet poorly understood relationship between spiritual wellbeing and positive youth outcomes, such as resilience. The author recommends measurement of resilience and strategies that aim to strengthen youth resilience should include spiritual wellbeing however, further research is required that considers how best to incorporate spiritual wellbeing into both resilience measures and health promoting strategies. It is also recommended that replica studies with people who belong to other spirituality types, and who may implement differing spiritual practices, are needed to test the proposed model of spiritual strengths and the identified relationship to resilience.

description: The biologic underpinnings of posttraumatic stress disorder (PTSD) have not been fully elucidated. Previous work suggests that alterations in the immune system are characteristic of the disorder. Identifying the biologic mechanisms by which such alterations occur could provide fundamental insights into the etiology and treatment of PTSD. Here we identify specific epigenetic profiles underlying immune system changes associated with PTSD. Using blood samples (n = 100) obtained froman ongoing, prospective epidemiologic study in Detroit, theDetroit Neighborhood Health Study, we applied methylation microarrays to assay CpG sites from more than 14,000 genes among 23 PTSD-affected and 77 PTSD-unaffected individuals. We show that immune system functions are significantly over represented among the annotations associated with genes uniquely unmethylated among those with PTSD. We further demonstrate that genes whose methylation levels are significantly and negatively correlated with traumatic burden show a similar strong signal of immune function among the PTSD affected. The observed epigenetic variability in immune function by PTSD is corroborated using an independent biologic marker of immune response to infection, CMV - a typically latent herpes virus whose activity was significantly higher among those with PTSD. This report of peripheral epigenomic and CMV profiles associated with mental illness suggests a biologic model of PTSD etiology in which an externally experienced traumatic event induces down stream alterations in immune function by reducing methylation levels of immune-related genes.

description: Objective. To evaluate two alternatives to the fasting plasma glucose (FPG) test for diabetes screening in Latin America. Methods. Eight hundred adults without diabetes were recruited in a primary care clinic in Honduras. An equation-based screening formula, incorporating a random capillary glucose test and other risk factors, was used for initial screening. All patients with a screening-based probability of diabetes > 20%, plus one-fifth of those with a probability < 20%, were asked to return for FPG and point-of-care hemoglobin A1c (POC-A1c) tests. An FPG ≥ 126 milligrams per deciliter and a POC-A1c ≥ 6.5% were used as gold standards to assess the performance of the screening equation. The association between the POC-A1c and the FPG tests was examined as were patient factors associated with failure to return for follow-up and variation in diabetes risk across subgroups. Results. The screening equation had excellent test characteristics compared with FPG and POC-A1c. Using the FPG gold standard, the POC-A1c had a sensitivity of 77.8% and a specificity of 84.9%. With an A1c cutoff of 7%, POC-A1c specificity increased to 96.2%. Thirty-four percent of patients asked to return for follow-up testing failed to do so. Those who failed to return were more likely to be men and to have hypertension. Conclusions. Both the screening equation and POC-A1c are reasonable alternatives to an FPG test for identifying patients with diabetes. Given the barriers to currently recommended screening procedures, these options could have important public health benefits in Latin America.

description: The range corrections to the universal properties and structure of two-neutron halo nuclei are investigated within an effective quantum mechanics framework. Treating the nucleus as an effective three-body system, we make a systematic improvement upon previous calculations by calculating the linear range corrections at next-to-leading order. Since the effective ranges for the neutron-core interactions are not known, we estimate the effective range to be set by the inverse of the pion mass. We investigate the possibility of excited Efimov states in two-neutron halo nuclei and calculate their mean square radii to next-to-leading order. We find that the effective range corrections are generally small and the leading order predictions are very robust.

Older women who live alone: an interpretive approach to bridging the gap between lived experiences and policy discourses
Creators: name: Forbes, JH
Publisher: name: University Of Tasmania
Year: 2023

description: I have applied an interpretive approach to an investigation of the gap between the lived experiences of older women who live alone and policy discourses on population ageing and housing. The research and policy literature on ageing and housing finds that older women who live alone are at increased risk of financial hardship and social marginalisation, issues that could be improved by housing policy responses; however, evidence on the perspectives of residents is limited. My major finding is that the social construction of 'ageing as a problem' in policy discourses differed in some important respects from the presentation and perspectives of the residents, and the issues that they identified. The study group members were 35 women, ranging in age from 53 to 87 years of age. I also interviewed eight workers from housing and aged care. The women were all interviewed in their homes, in urban and regional locations in Southern Tasmania. All but one of the workers1, were interviewed in workplaces. The discourses of women and workers were analysed for themes and then compared. The main themes I identified from interviews with the women were caring for and considering others, making light of problems and inconveniences, and staying independent and not being a burden. The main themes I identified from interviews with workers were 'they' are vulnerable and lonely, 'they' need specialised housing, and 'they' won't move. However, both the women and workers agreed on one key point: that older women, who live alone, lack access to affordable and appropriate housing options. In the Findings section, at Table 3, I have presented these competing interpretations of housing issues for older women as a hypothetical conversation between the women and the workers. The voices of the study group women have provided a counter-narrative to ageism in policy discourses that has recast these older women who live alone in a positive light, as resourceful and resilient not vulnerable and lonely. I have then drawn parallels between policy discourses on ageing and three typologies for the analysis of social exclusion discourses identified by Levitas (1998) which have served to perpetuate the stigmatisation and social marginalisation of disadvantaged people like these women. I have concluded by making suggestions, through a Utopian lens (Levitas, 2003; 2001), for policies that respond to input from the women I interviewed. I have suggested a new era of respecting older people, a coherent national policy response to housing an ageing population, rejection of institutional accommodation options, creation of age-friendly housing and communities, and a system of services and subsidies to help older residents maintain their independence for as long as possible, including mentoring services to help them with complex decision-making about moving or staying.
Subjective evaluation and comparison of digital and analog modulation systems
Creators: name: Douville, Rene
Publisher: name: University of British Columbia
Year: 2011

description: The ultimate measure of performance of any communication system is the subjective quality of the received message. In this thesis, the subjective quality of the output of a differential pulse code modulation (DPCM) system was measured as a function of the number of bits of quantization L, the speech bandwidth W, the ratio r of the sampling frequency fs to the Nyquist frequency 2W, and the number of feedback samples N. For previous-sample feedback (N = 1) the maximum subjective quality was obtained as a function of the bit rate R = 2rWL. The optimum sampling rate .was found to be the Nyquist rate; the improvement afforded by increasing fs over 2W was more than offset by the required increase in bit rate. Noise in the feedback loop caused by dc offset errors and noise present in the output of the feedback coefficient amplifiers prevented a thorough investigation of two- and three- sample feedback, although some results were obtained. The subjective quality of delta modulated (ΔM) speech was obtained vs r and W, and the quality of amplitude modulated (ΔM) speech was measured as a function of W and channel signal-to-noise ratio. A technique was then devised to use the AM results to estimate the subjective quality of phase modulated (PM) speech. A comparison was then made of the capabilities of PCM, DPCM, AM, single sideband-AM (SSB-AM), double sideband-AM (DSB-AM), and PM. It was found that when the available channel capacity is small, SSB-AM and DSB-AM are subjectively better than PCM', DPCM, and ΔM. However, for high quality speech communication, DPCM requires less channel capacity than PCM, ΔM, DSB-AM, SSB-AM or PM.
Studies on the ultrastructure of desmids and its relation to their taxonomy
Creators: name: Gerrath, Joseph Fredrick
Publisher: name: University of British Columbia
Year: 2011

description: The cell wall was studied in 13 species in 10 genera of the Desmidiaceae in order to determine whether ultrastructural differences exist among the three subfamilies of the Desmidiaceae: Penieae. Closterieae, and Cosmarieae. The cell wall of the Penieae comprises two distinct layers, an inner layer of cellulose microfibrils and an outer electron-dense layer. The semicell walls do not overlap at the isthmus region and the lack of pores in the wall is confirmed. The cell wall of the Closterieae is one-layered without pores and the semicell walls overlap where they join. The cell wall of the Cosmarieae is one-layered with pores through which a pectic fibrillar sheath is secreted. The semicell walls overlap at the isthmus. In the unicellular Cosmarieae an initial wall lacking pores is present during elongation of the new semicell following cell division. This initial wall is discarded after formation of the mature cell wall containing pores. In the filamentous Cosmarieae both initial and mature cell walls are formed before semicell elongation occurs. In the colonial desmid, Cosmocladium saxonicum, the connecting strands between cells comprise several fibrillar subunit strands each associated with one of a group of pores near the isthmus of the cell. Cytoplasmic microtubules are present immediately below the plasma membrane in the isthmus region of cells fixed with glutaraldehyde. These microtubules are oriented perpendicular to the cell axis. A single cell at metaphase of Spondylosium nulchrum was examined. Evidence for the existence of localized centromeres in the chromosomes of this species is presented. Bundles of spindle microtubules attach to the metaphase chromosomes at localized regions and not at any other part of the chromosome. The rarely collected species Pleurotaenium spinulosum (Wolle) Brunei (Cosmarieae) has a cell wall with the same fine structure as in the genus Penium (Penieae). The transfer of this species to the genus Penium as Penium spinulosum (Wolle) comb. nov. is therefore proposed.

description: We have derived the unitarity bounds in the high energy limit for the minimal B-L extension of the Standard Model by analysing the full class of Higgs and would-be Goldstone boson two-to-two scatterings at tree level. Moreover, we have investigated how these limits could vary at some lower critical value of the energy.

description: Background: Systemic inflammation is linked to cardiovascular risk, but the influence of persistent pathogens, which are conventionally dichotomously categorized, on circulating levels of inflammatory markers is not clear. Antibody levels of pathogens have not been examined in relation to inflammation. Methods. Using data from a subsample of the Multi-Ethnic Study of Atherosclerosis, we examined circulating levels of interleukin-6 (IL-6), C-reactive protein (CRP) and fibrinogen in relation to five common persistent pathogens: cytomegalovirus, herpes simplex virus-1, Hepatitis A virus, Helicobacter pylori and Chlamydia pneumoniae. We tested the hypothesis that the number of seropositive pathogens (based on conventional cut-off points) would not be as sensitive a marker of inflammation as immune response measured by antibody levels to pathogens. Results. High antibody response to multiple pathogens showed graded and significant associations with IL-6 (p < 0.001), CRP (p = 0.04) and fibrinogen (p = 0.001), whereas seropositive pathogen burden did not. In multiple linear regression models, high antibody response to multiple pathogens maintained a positive association only with IL-6 (4.4% per pathogen exhibiting high antibody response, 95% CI 0.0-8.9). Conclusions. High antibody response to pathogens was a more consistent marker of inflammatory outcomes compared to seropositivity alone and high antibody response to multiple pathogens was a stronger marker compared to any single pathogen.

description: We present an analysis of three years of precision radial velocity measurements of 160 metal-poor stars observed with HIRES on the Keck 1 telescope. We report on variability and long-term velocity trends for each star in our sample. We identify several long-term, low-amplitude radial-velocity variables worthy of follow-up with direct imaging techniques. We place lower limits on the detectable companion mass as a function of orbital period. Our survey would have detected, with a 99.5% confidence level, over 95% of all companions on low-eccentricity orbits with velocity semi-amplitude K > 100 m/s, or M_p*sin(i) > 3.0 M_JUP*(P/yr)^(1/3), for orbital periods P< 3 yr. None of the stars in our sample exhibits radial-velocity variations compatible with the presence of Jovian planets with periods shorter than the survey duration. The resulting average frequency of gas giants orbiting metal-poor dwarfs with -2.0 < [Fe/H] < -0.6 is f_p<0.67% (at the 1-sigma confidence level). We examine the implications of this null result in the context of the observed correlation between the rate of occurrence of giant planets and the metallicity of their main-sequence solar-type stellar hosts. By combining our dataset with the Fischer & Valenti (2005) uniform sample, we confirm that the likelihood of a star to harbor a planet more massive than Jupiter within 2 AU is a steeply rising function of the host's metallicity. However, the data for stars with -1.0 < [Fe/H] < 0.0 are compatible, in a statistical sense, with a constant occurrence rate f_p~1%. Our results can usefully inform theoretical studies of the process of giant planet formation across two orders of magnitude in metallicity.
