Epidemiology

description: Background: Excessive sedentary time is ubiquitous in Western societies. Previous studies have relied on self-reporting to evaluate the total volume of sedentary time as a prognostic risk factor for mortality and have not examined whether the manner in which sedentary time is accrued (in short or long bouts) carries prognostic relevance. Objective: To examine the association between objectively measured sedentary behavior (its total volume and accrual in prolonged, uninterrupted bouts) and all-cause mortality. Design: Prospective cohort study. Setting: Contiguous United States. Participants: 7985 black and white adults aged 45 years or older. Measurements: Sedentary time was measured using a hip-mounted accelerometer. Prolonged, uninterrupted sedentariness was expressed as mean sedentary bout length. Hazard ratios (HRs) were calculated comparing quartiles 2 through 4 to quartile 1 for each exposure (quartile cut points: 689.7, 746.5, and 799.4 min/d for total sedentary time; 7.7, 9.6, and 12.4 min/bout for sedentary bout duration) in models that included moderate to vigorous physical activity. Results: Over a median follow-up of 4.0 years, 340 participants died. In multivariable-adjusted models, greater total sedentary time (HR, 1.22 [95% CI, 0.74 to 2.02]; HR, 1.61 [CI, 0.99 to 2.63]; and HR, 2.63 [CI, 1.60 to 4.30]; P for trend < 0.001) and longer sedentary bout duration (HR, 1.03 [CI, 0.67 to 1.60]; HR, 1.22 [CI, 0.80 to 1.85]; and HR, 1.96 [CI, 1.31 to 2.93]; P for trend < 0.001) were both associated with a higher risk for all-cause mortality. Evaluation of their joint association showed that participants classified as high for both sedentary characteristics (high sedentary time [≥12.5 h/d] and high bout duration [≥10 min/bout]) had the greatest risk for death. Limitation: Participants may not be representative of the general U.S. population. Conclusion: Both the total volume of sedentary time and its accrual in prolonged, uninterrupted bouts are associated with all-cause mortality, suggesting that physical activity guidelines should target reducing and interrupting sedentary time to reduce risk for death.

description: No abstracts are to be cited without prior reference to the author.The impacts of an offshore fish farm in Alghero bay (northwest Sardinia, Italy) on the benthic ecosystem were investigated during 2007 and 2008. Together with chemical and physical characteristics of the area (i.e. currents, sediment analyses), some biological analysis were performed. AZTI’s Marine Biotic Index (AMBI) and the Multivariate AMBI (M-AMBI) are used to assess the ecological status of benthic communities within the European Water Framework Directive (WFD). Here, clear gradients of impact were detected using both methods, and they are related to the farm production, prevailing currents, and characteristics of the area (i.e. water depth, distance to the cages). The most degraded situation was detected within 84 m of the cages, whereas the area undegraded was further than 907 m from the cages. The gradient is shown by decreasing AMBI values and opportunistic species percentages, and increasing richness, diversity, and sensitive species. This study highlights the importance of setting reference conditions for different areas when calculating M-AMBI. These reference conditions correspond to those in undisturbed sites, in the opposite of the prevailing currents within the area.

description: This is a review of recent developments in Monte Carlo methods in the field of ultra cold gases. For bosonic atoms in an optical lattice we discuss path integral Monte Carlo simulations with worm updates and show the excellent agreement with cold atom experiments. We also review recent progress in simulating bosonic systems with long-range interactions, disordered bosons, mixtures of bosons, and spinful bosonic systems. For repulsive fermionic systems determinantal methods at half filling are sign free, but in general no sign-free method exists. We review the developments in diagrammatic Monte Carlo for the Fermi polaron problem and the Hubbard model, and show the connection with dynamical mean-field theory. We end the review with diffusion Monte Carlo for the Stoner problem in cold gases.

description: No abstracts are to be cited without prior reference to the author.Recently, the concepts of natural resources management and marine spatial planning have been incorporated in many directives (Water Framework Directive, Marine Strategy Directive, Habitat and Bird Directive). For the implementation of these directives, policy-makers and managers need tools for evaluating impacts in the marine system, and for the assessment of recovery after enforcement of measures. Biotic indices were designed to objectively evaluate changes in the ecosystem because of impacts or measures. An example of such a tool is the Benthic Ecosystem Quality Index (BEQI), which objectively scales the observed difference between impact and control data in five classes (bad to high; www.beqi.eu). To this aim, the BEQI uses the benthic parameters density, biomass, number of species, and species composition to evaluate changes in benthic community characteristics. In addition, a habitat level is included in the approach to assess changes in the hydromorphological aspects of a water body. The BEQI was tested for several case studies in Belgian and Dutch waters: eutrophication/stratification and restoration measures in the Veerse Meer, invasive alien species in coastal waters, physical disturbance resulting from dredge disposal along the Belgian Coast, and hydromorphological changes in Dutch estuaries. The results of the analyses indicate that the different parameters of the BEQI index show a clear and specific response to each impact type. Consequently, the tool can be considered useful to give managers scaled information about the impact degree of different pressure types.

description: We have designed a simple multi-scale method that identifies turbulent motions in hydrodynamical grid simulations. The method does not assmume ant a-priori coherence scale to distinguish laminar and turbulent flows. Instead, the local mean velocity field around each cell is reconstructed with a multi-scale filtering technique, yielding the maximum scale of turbulent eddies by means of iterations. The method is robust, fast and easily applicable to any grid simulation. We present here the application of this technique to the study of spatial and spectral properties of turbulence in the intra cluster medium, measuring turbulent diffusion and anisotropy of the turbulent velocity field for a variety of driving mechanisms: a) accretion of matter in galaxy clusters (simulated with ENZO); b) sloshing motions around cool-cores (simulated with FLASH); c) jet outflows from active galactic nuclei, AGN (simulated with FLASH). The turbulent velocities driven by matter accretion in galaxy clusters are mostly tangential in the inner regions (inside the cluster virial radius) and isotropic in regions close to the virial radius. The same is found for turbulence excited by cool core sloshing, while the jet outflowing from AGN drives mostly radial turbulence motions near its sonic point and beyond. Turbulence leads to a diffusivity in the range =10^29-10^30 cm^2/s in the intra cluster medium. On average, the energetically dominant mechanism of turbulence driving in the intra cluster medium is represented by accretion of matter and major mergers during clusters evolution.

 Diagnosis. Male postabdomen: pregonite with one weak seta on dorsal portion (Figs 42, 46, 51, 56, 60, 65); epiphallus absent or present; distiphallus subrectangular in lateral view.
 Remarks. Monophyly of this group is provided by one short seta on the dorsal part of the male pregonite. The seta of the S. siphonoides group is distinctly different from that of Ceranthia which is strong and long. According to ANDERSEN (1996), among the European Aphantorhaphopsis species, S. (A.) brunnescens (Villeneuve), S. (A.) siphonoides (Strobl), S. (A.) starkei (Mesnil) and S. (A.) verralli (Wainwright) have the seta on the pregonite. The following East Asian and Oriental species are included in this group: S. (A.) alticola (Mesnil), S. (A.) crassulata (Mesnil), S. (A.) curta sp. nov., S. (A.) laticornis (Malloch), and S. (A.) orientalis (Townsend).

description: No abstracts are to be cited without prior reference to the author.The Basque coast (southeastern part of the Bay of Biscay) presents specific environmental and biogeographical conditions with regard to the rest of the French Atlantic coast: warmer water temperatures, lower tidal range, and strong regime of swell. Hence, macroalgal communities exhibit some specificities within this area: rare occurrence of fucoids and kelps, smaller number of belts (less marked vertical zonation), and species characteristic of the southern coasts of Europe. The Water Framework Directive uses macroalgae as one of the biological quality elements in assessing the ecological status of coastal waters. In this context, the abovementioned specificities must be taken into account when applying any method of assessment. In the Atlantic French coasts two methods have been tested: a Breton protocol, used on the French coasts of both the Channel and the Atlantic Ocean, and the Spanish method, used in the north coast of Spain. The site chosen to test these protocols is called “The Twins”, in the domain of Abbadia (Hendaye), on the border between France and Spain. The sampling survey took place during the same cycle of high tides, at the end of June 2009. The first results on the quality status of macroalgae show that these two protocols are relevant with coherent indicators, not only with regard to the reference values but also with regard to results obtained for this element on the nearby Spanish Basque coast.

description: Gauged linear sigma models with (0,2) supersymmetry allow a larger choice of couplings than models with (2,2) supersymmetry. We use this freedom to find a fully linear construction of torsional heterotic compactifications, including models with branes. As a non-compact example, we describe a family of metrics which correspond to deformations of the heterotic conifold by turning on H-flux. We then describe compact models which are gauge-invariant only at the quantum level. Our construction gives a generalization of symplectic reduction. The resulting spaces are non-Kahler analogues of familiar toric spaces like complex projective space. Perturbatively conformal models can be constructed by considering intersections.

description: Despite the fact that Egypt's eras of political disintegration were fewer, shorter, and milder than those experienced by any of the other civilizations discussed in this volume, the aftermath of governmental collapse in the Nile Valley was nonetheless both traumatic and transformative for those who experienced it. Within this chapter I explore, utilizing both archaeological and textual lines of evidence, the ramifications of the radical reshaping of social order that occurred during the First Intermediate Period. I argue that although numerous parallels can be drawn between the processes of state formation and those of state re-formation in Egypt, it is misleading to regard the latter as a simple replay of the former.
Bayesian Implications of Current LHC and XENON100 Search Limits for the Constrained MSSM

description: The CMS Collaboration has released the results of its search for supersymmetry, by applying an alphaT method to 1.1/fb of data at 7 TeV. The null result excludes (at 95% CL) a low-mass region of the Constrained MSSM's parameter space that was previously favored by other experiments. Additionally, the negative result of the XENON100 dark matter search has excluded (at 90% CL) values of the spin-independent scattering cross sections sigma^SI_p as low as 10^-8 pb. We incorporate these improved experimental constraints into a global Bayesian fit of the Constrained MSSM by constructing approximate likelihood functions. In the case of the alphaT limit, we simulate detector efficiency for the CMS alphaT 1.1/fb and validate our method against the official 95% CL contour. We identify the 68% and 95% credible posterior regions of the CMSSM parameters, and also find the best-fit point. We find that the credible regions change considerably once a likelihood from alphaT is included, in particular the narrow light Higgs resonance region becomes excluded, but the focus point/horizontal branch region remains allowed at the 1sigma level. Adding the limit from XENON100 has a weaker additional effect, in part due to large uncertainties in evaluating sigma^SI_p, which we include in a conservative way, although we find that it reduces the posterior probability of the focus point region to the 2sigma level. The new regions of high posterior favor squarks lighter than the gluino and all but one Higgs bosons heavy. The dark matter neutralino mass is found in the range 250 GeV sg), which is exacerbated by including the alphaT limit; each constraint favors a different region of the CMSSM's mass parameters.

Spoofing proofing : the logical-narratological construction of Carroll's Alice books

description: This paper explores Charles Lutwidge Dodgson’s (Lewis Carroll’s) use of a reductio ad absurdum proof in both Alice’s Adventures in Wonderland (1865) and Through the Looking-Glass, and What Alice Found There (1872). It seeks to show that Dodgson used this proof as a framework for the first novel in order to mock “new mathematics,” including but not limited to n-dimensional theories of space, imaginary and negative numbers, and non-Euclidean geometries. It also problematizes this reading of Wonderland through its exploration of Dodgson’s continued used of reductio ad absurdum as framework in Looking-Glass, in which he explores theoretical mathematics for which he held genuine interest. In doing so, the paper reviews Victorian developments in mathematics and the epistemological and theological shifts that these developments presaged. It also examines Dodgson’s particular interests, and in particular, his contradictory views in mathematics. It therefore seeks to undermine the canonical view of Carroll as a simple, less-than-brilliant mathematician through its examination of his most famous books’ fictional explorations of the worlds of mathematics.

description: We study high-field magnon dynamics and examine the dynamical structure factor in the quasi-2D tetragonal Heisenberg antiferromagnet with interlayer coupling corresponding to realistic materials. Within spin-wave theory, we show that a non-zero interlayer coupling mitigates singular corrections to the excitation spectrum occurring in the high-field regime that would otherwise require a self-consistent approach beyond the 1/S approximation. For the fields between the threshold for decays and saturation field we observe widening of the two-magnon sidebands with significant shifting of the spectral weight away from the quasiparticle peak. We find spectrum broadening throughout large regions of the Brillouin zone, dramatic redistributions of spectral weight to the two-magnon continuum, two-peak structures and other features clearly unlike conventional single-particle peaks.

description: No abstracts are to be cited without prior reference to the author.The Water Framework Directive suggests the use of abundance and species composition of macrophytes for ecological quality classification. In the case of the Atlantic coastal waters, three bio-indicators based in seaweed communities have been proposed: the RSL (Reduced Species List), the CFR (quality of rocky bottoms), and the P-MarMAT (Portuguese Marine Macroalgae Assessment Tool). The ecological differences between the coasts where these index have been developed and the coasts of southern Spain make necessary a calibration for these coasts. In this study, the RSL index was adapted for the rocky shores of Cádiz, and a reduced species list developed. Two new parameters are proposed to estimate the index: proportion of competitors and proportion of ruderals, instead of the proportions of Ecological Status Group I (ESG I) and opportunists, respectively. Based on nutrients and turbidity data, 16 sites along the Atlantic coast of Cádiz were classified into three categories—high, good, and moderate. According to this classification, the RSL index was calibrated. The results of both indices (RSL and modified RSL) were compared with the previous classification. Except for proportion of ESG I and species richness, all parameters showed significant differences between the ecological quality classifications. The most significant boundary is the one lying between moderate and good status. Both versions of the RSL index are suitable to assess the ecological status at a middle spatial scale. The results have also shown the existence of two zones with a different intertidal seaweed species composition: Atlantic Cádiz and the Gibraltar Strait.

description: MAXI J1659-152 is a bright X-ray transient black-hole candidate binary system discovered in September 2010. We report here on MAXI, RXTE, Swift, and XMM-Newton observations during its 2010/2011 outburst. We find that during the first one and a half week of the outburst the X-ray light curves display drops in intensity at regular intervals, which we interpret as absorption dips. About three weeks into the outbursts, again drops in intensity are seen. These dips have, however, a spectral behaviour opposite to that of the absorption dips, and are related to fast spectral state changes (hence referred to as transition dips). The absorption dips recur with a period of 2.414+/-0.005 hrs, which we interpret as the orbital period of the system. This implies that MAXI J1659-152 is the shortest period black-hole candidate binary known to date. The inclination of the accretion disk with respect to the line of sight is estimated to be 65-80 degrees. We propose the companion to the black-hole candidate to be close to an M5 dwarf star, with a mass and radius of about 0.15-0.25 M_sun and 0.2-0.25 R_sun, respectively. We derive that the companion had an initial mass of about 1.5 M_sun, which evolved to its current mass in about 5-6 billion years. The system is rather compact (orbital separation of larger than ~1.33 R_sun), and is located at a distance of 8.6+/-3.7 kpc, with a height above the Galactic plane of 2.4+/-1.0 kpc. The characteristics of short orbital period and high Galactic scale height are shared with two other transient black-hole candidate X-ray binaries, i.e., XTE J1118+480 and Swift J1735.5-0127. We suggest that all three are kicked out of the Galactic plane into the halo, rather than being formed in a globular cluster.

description: We present a formulation of the operator product expansion that is infrared finite to all orders in the attendant massless non-Abelian gauge theory coupling constant, which we will often-times associate with the QCD theory, the theory that we actually have as our primary objective in view of the operation of the LHC at CERN. We make contact in this way with the recently introduced IR-improved DGLAP-CS theory and point-out phenomenological implications accordingly, with an eye toward the precision QCD theory for LHC physics.

description: No abstracts are to be cited without prior reference to the author.In the context of the Water Framework Directive (WFD), the Water Agency Rhône Méditerranée—Corse intends to develop a new benthic biotic index based on foraminiferal faunas. Existing benthic indices, mainly based on macrofauna, present significant drawbacks such as the large sediment volume required, the difficulty of establishing the initial ecological state of the study area and the lack of specialists for taxonomic identification. Foraminifera are unicellular marine micro-organisms that calcify or aggregate particles to form their tests. Their principal asset is that their tests remain in the sediment after their death. Therefore, the analysis of dead fauna gives an image of the environmental conditions in the past. The study of foraminiferal faunas presents other advantages: (i) the sediment volume required to obtain statistically significant data is small, (ii) their life cycle is short so they react rapidly to environmental changes, and (iii) identification of benthic foraminifera to species level is relatively easy compared with macrofauna. In this context, we study benthic foraminiferal faunas from the French Mediterranean coast (mainland and Corsica) to develop a biotic index. For each water body defined by the WFD in our study area, we study the density, diversity, and distribution of foraminiferal faunas. The analyses of the dead faunas can inform us about the environmental conditions at these stations in a historical past, prior to the sampling period (March 2009). If successful, this foraminiferal bio-indicator method will be proposed for implementation in the Marine Strategy Framework Directive.

Regulation of the PhoP-PhoQ two-component system in Pseudomonas aeruginosa and its role in virulence
Creators: name: Gellatly, Shaan Lae

description: Pseudomonas aeruginosa is an opportunistic bacterial pathogen that can cause severe infections in individuals with underlying medical conditions. P. aeruginosa primarily infects at epithelial surfaces where it interacts initially via type IV pili, flagella and LPS. Two component regulatory systems control many aspects of pseudomonal physiology and mediate adaptation to environmental changes including those that occur in the host. This thesis outlines the contributions of these systems to the cytotoxicity to epithelial cells and sheds light on the regulation mediated by the two-component sensor PhoQ. Systems that contributed to cytotoxicity fell into several themes including motility, cyclic-di-GMP regulation, and carbon and nitrogen utilization. Several genes controlled by PhoQ were shown to be dysregulated during infection of lung epithelial cells, including upregulation of oprH-phoP-phoQ, the lipid A modification gene arnB, and downregulation of a lipid A deacylase, pagL. Consistent with this, lipid A from a phoQ mutant grown in varying magnesium concentrations displayed alterations. LPS of the phoQ mutant revealed increased inflammatory properties as demonstrated by increased secretion of the cytokines IL6, TNFalpha , and IL10 from PBMCs. The decrease in cytotoxicity of a phoQ mutant correlated with a decrease in secretion of lipases and proteases when co-incubated with cultured epithelial cells. These results suggest that the PhoP-PhoQ system might adapt the bacterium to lung epithelia and that this might contribute to and be exacerbated by the selective pressure of inhaled polymyxin therapeutics. Unlike most sensor kinases that phosphorylate their cognate response regulators, PhoQ of P. aeruginosa appears to act only as a phosphatase of its cognate regulator PhoP. Here it was demonstrated that PhoP was not activated by PhoQ in a luminescence reporter screen. The sensor kinase, RoxS, involved in regulation of the cyanide insensitive oxidase, was revealed as a candidate phosphodonor to PhoP. Since mutation of roxS was able to reduce but not eliminate expression from the oprH-phoP-phoQ operon, it is conceivable that other sensors contribute to PhoP phosphorylation. It was also demonstrated that PhoP contributed to the known polymyxin resistance of a phoQ mutant but only partially to cytotoxicity. These results emphasize the complexity of the PhoP-PhoQ regulatory system.

description: Due to gluon saturation, the growth of the inelastic nucleon-nucleon cross section with increasing collision energy sqrt(s) results in a broadening of the nucleon's density distribution in position space. This leads to a natural smoothing of the initial energy density distribution in the transverse plane of the matter created near midrapidity in heavy-ion collisions. We study this effect for fluctuating initial conditions generated with the Monte Carlo Kharzeev-Levin-Nardi (MC-KLN) model for Au+Au collisions at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC). We argue that at the LHC viscous hydrodynamics is applicable at earlier times than at RHIC, not only because of the higher temperature but also since the length scale over which the initial pressure fluctuates increases with collision energy.

description: Quantum criticality is a central concept in condensed matter physics, but the direct observation of quantum critical fluctuations has remained elusive. Here we present an x-ray diffraction study of the charge density wave (CDW) in 2H-NbSe2 at high pressure and low temperature, where we observe a broad regime of order parameter fluctuations that are controlled by proximity to a quantum critical point. X-rays can track the CDW despite the fact that the quantum critical regime is shrouded inside a superconducting phase, and, in contrast to transport probes, allow direct measurement of the critical fluctuations of the charge order. Concurrent measurements of the crystal lattice point to a critical transition that is continuous in nature. Our results confirm the longstanding expectations of enhanced quantum fluctuations in low dimensional systems, and may help to constrain theories of the quantum critical Fermi surface.

description: No abstracts are to be cited without prior reference to the author.Most efforts in the assessment of the ecological status of marine waters have focused on the macroalgal or zoobenthos components separately. The aim of this work is to develop a new methodology for the assessment of coastal waters quality of the Basque coast according to the European Water Framework Directive (WFD, 2000/60/EC), based on both: algae and invertebrates of rocky intertidal communities. Part of the data used to develop this new protocol was collected during a monitoring study carried out in the Abra de Bilbao and adjacent coast (Basque Country, northern Spain) during the gradual application of a sewerage plan for the metropolitan area of Bilbao. Five sampling stations (including a reference site) distributed along the pollution gradient were studied biannually from 1996 to 2008. Data were also collected from five reference sites during year 2009. The habitat selected to develop the index comprises the tidal fringe from 0.5 m to 1.5 m above low spring tides. A quality index of rocky intertidal communities (RICQI; Rocky Intertidal Communities Quality Index) was calculated on the basis of two known gradients: a spatial and a temporal one. The index combines the abundance data of bio-indicator species as well as various measures of the community: species richness and diversity of algae and invertebrates, algal cover (%), fauna cover (%), fauna/total cover ratio, abundance of different macroalgal functional groups, and trophic strategies.

description: Obesity is a major factor in development of insulin resistance (IR) and metabolic features in polycystic ovary syndrome (PCOS) patients. Nearly two-thirds patients with PCOS (30 of 37 confirmed cases of PCOS) in our previous community based study were lean, in contrast to Caucasians. Metabolic parameters including IR and β cell function have not been characterized well in this group of lean PCOS. To study the metabolic features including IR and β cell function in lean PCOS patients, 53 patients with BMI, <23 kg/m2 were compared with 71 obese PCOS and 45 age and body mass index matched controls. Lean patients had similar β cell function and IR as compared to controls and obese patients, though the latter group had more metabolic abnormality. Fasting c-peptide and its ratio to glucose were significantly higher in lean patients compared to controls. In subset of subjects with five point OGTT, disposition index and Matsuda index (MI) showed significant negative correlation with BMI and blood pressure. MI also negatively correlated with waist, WHR, and HOMAB. High fasting C-peptide is probably a class effect as is seen in both lean and obese PCOS.

description: This paper introduces a novel meta-learning algorithm for time series forecasting. The efficient Bayesian multivariate surface regression approach is used to model forecast error as a function of features calculated from the time series. The minimum predicted forecast error is then used to identify an individual model or combination of models to produce forecasts. In general, the performance of any meta-learner strongly depends on the reference dataset used to train the model. We further examine the feasibility of using GRATIS (a feature-based time series simulation approach) in generating a realistic time series collection to obtain a diverse collection of time series for our reference set. The proposed framework is tested using the M4 competition data and is compared against several benchmarks and other commonly used forecasting approaches. The new approach obtains performance comparable to the second and the third rankings of the M4 competition.
