description: Abstract Background South Africa has 6.4 million adults over the age of 15 living with HIV. Gender inequality issues continue to drive the HIV epidemic in South Africa, where Black African women bear the greatest HIV burden. Limited access to services; little capacity to negotiate sex and condom use; and other legal, social, and economic inequities make women highly vulnerable to HIV infection. Behavioral interventions have been shown to decrease risk behaviors, but they have been less successful in reducing HIV incidence. Conversely, biomedical prevention strategies have proven to be successful in reducing HIV incidence, but require behavioral interventions to increase uptake and adherence. Consequently, there is a need for integrated approaches that combine biomedical and behavioral interventions. Effective combination prevention efforts should comprise biomedical, behavioral, and structural programming proven in randomized trials that focuses on the driving forces and key populations at higher risk of HIV infection and transmission. Methods/Design This prospective, geographically clustered randomized field experiment is enrolling participants into two arms: a control arm that receives standard HIV testing and referral for treatment; and an intervention arm that receives an evidence-based, woman-focused behavioral intervention that emphasizes risk reduction and retention, the Women’s Health CoOp. We divided the city of Pretoria into 14 mutually exclusive geographic zones and randomized these zones into either the control arm or the intervention arm. Outreach workers are recruiting drug-using women from each zone. At baseline, eligible participants complete a questionnaire and biological testing for HIV, recent drug use, and pregnancy. Follow-up interviews are completed at 6 and 12 months. Discussion The biobehavioral intervention in this study merges an efficacious behavioral HIV prevention intervention for women with biomedical prevention through HIV treatment as prevention using a Seek, Test, Treat and Retain strategy. This combination biobehavioral intervention is designed to (1) improve the quality of life and reduce HIV infectiousness among women who are HIV positive, and (2) reduce HIV risk behaviors among women regardless of their HIV status. If efficacious, this intervention could help control the HIV epidemic in South Africa. Trial registration Trial registration no: NCT01497405.

description: We calculate two-photon exchange (TPE) amplitudes for the elastic electron-proton scattering, and take into account intermediate hadronic states containing πN system with total angular momentum 1/2 or 3/2, which includes 8 different channels. This is the improvement of our previous calculation, where only the πN states with quantum numbers of Δ(1232) resonance were included. The results show good consistency with recent experimental data. At high Q^2, newly-calculated contributions affect the correction to the measured proton form factor ratio μG_E/G_M. The total correction becomes somewhat smaller compared to our previous work, but is still significant and grows approximately linearly with Q^2. Comparing contributions of different channels, we found that larger contributions come from the channels with quantum numbers of lightest resonances.

description: Garden visiting has become a popular leisure pursuit in recent years. Within a tourism and recreation context, scant research exists on the subject of gardens as recreational resources and the manner in which they are presented to and consumed by the public. This thesis explores the scope and nature of gardens as tourism and recreation resources in the UK. The thesis examines the conceptual foundations of the garden, in order to establish what reasons explain predisposition towards garden visiting, and why gardens provide a desirable environment in which people want to spend leisure time. The activity of garden visiting is analysed using a two-dimensional approach, which takes into account the supply of gardens open to the public and the demand for garden visits. In this respect, the supply-side relates to the perceptions of garden owners/mangers, while the demand aspect is linked with the outlook of garden visitors. Uniting these two perspectives yields an intriguing area of research, that of the visitor experience, how that experience is perceived and managed, and which elements are crucial in its formation. Understanding the visitor experience is a critical for operators of garden attractions, in line with all attractions. This thesis presents the results of two surveys, one of garden owners/managers (n=546) and one of garden visitors (n=593). Data analysis provides a source of information on the range and characteristics of gardens open to the public, approaches to managing the visitor experience and issues for owners/managers in relation, to operating a garden visitor attraction as well as visitors characteristics, motivations; behaviour and perceptions of the garden experience. The data generated allows the identification of a range of themes and implications for the operators of garden attractions, in particular those issues that will influence future development.
Regulation of pancreatic cancer cell migration and invasion by RhoC GTPase and Caveolin-1

Publisher: name: BioMed Central Ltd
Year: 2005

description: Abstract Background In the current study we investigated the role of caveolin-1 (cav-1) in pancreatic adenocarcinoma (PC) cell migration and invasion; initial steps in metastasis. Cav-1 is the major structural protein in caveolae; small Ω-shaped invaginations within the plasma membrane. Caveolae are involved in signal transduction, wherein cav-1 acts as a scaffolding protein to organize multiple molecular complexes regulating a variety of cellular events. Recent evidence suggests a role for cav-1 in promoting cancer cell migration, invasion and metastasis; however, the molecular mechanisms have not been described. The small monomeric GTPases are among several molecules which associate with cav-1. Classically, the Rho GTPases control actin cytoskeletal reorganization during cell migration and invasion. RhoC GTPase is overexpressed in aggressive cancers that metastasize and is the predominant GTPase in PC. Like several GTPases, RhoC contains a putative cav-1 binding motif. Results Analysis of 10 PC cell lines revealed high levels of cav-1 expression in lines derived from primary tumors and low expression in those derived from metastases. Comparison of the BxPC-3 (derived from a primary tumor) and HPAF-II (derived from a metastasis) demonstrates a reciprocal relationship between cav-1 expression and p42/p44 Erk activation with PC cell migration, invasion, RhoC GTPase and p38 MAPK activation. Furthermore, inhibition of RhoC or p38 activity in HPAF-II cells leads to partial restoration of cav-1 expression. Conclusion Cav-1 expression inhibits RhoC GTPase activation and subsequent activation of the p38 MAPK pathway in primary PC cells thus restricting migration and invasion. In contrast, loss of cav-1 expression leads to RhoC-mediated migration and invasion in metastatic PC cells.

description: Previous studies have estimated distributions of seed dispersal distance by a variety of methods. But apart from direct observation, these methods cannot clarify the absolute numbers of seeds dispersed by each disperser. Without the ability to calculate absolute spreading volumes, each dispersers’ contribution cannot be quantitatively evaluated. To resolve this problem, we estimated and compared quantities and distances of seed dispersal by mammalian seed dispersers. We focused on the fruits of Cerasus leveilleana and five species of frugivorous mammals that forage on it, central Japan. We tracked wild individuals of each species and gut retention times of seeds in captive individuals. By observing wild C. leveilleana trees for 2 years, we calculated fruit production, visitation frequency, and numbers of fruits removed per visit by each species. The mammal species differed greatly in body size and foraging behavior, and thus in the seed dispersal patterns that they generated: not only in dispersal distance, especially long distance, but also in the number of seeds removed. In particular, total seed removal and long-distance dispersal tended to be greater when fruit production was greater, and they were strongly affected by occasional visitation by bears. Therefore, understanding the relative functional importance of seed dispersers requires direct comparison of their effectiveness at seed dispersal. Large differences in the seed disperser fauna between years due to interannual variation in fruit production suggest that observations of many trees with different amounts of fruit production over multiple years are needed to clarify how fruiting trees and seed dispersers interact.

A large narrow band H$α$ survey at $z\sim0.2$: the bright end of the luminosity function, cosmic variance and clustering across cosmic time

description: We carried out the largest ($>3.5\times10^5$ Mpc$^3$, 26 deg$^2$) H$α$ narrow band survey to date at $z\sim0.2$ in the SA22, W2 and XMMLSS extragalactic fields. Our survey covers a large enough volume to overcome cosmic variance and to sample bright and rare H$α$ emitters up to an observed luminosity of $\sim10^{42.4}$ erg s$^{-1}$, equivalent to $\sim11 M_\odot$ yr$^{-1}$. Using our sample of $220$ sources brighter than $>10^{41.4}$ erg s$^{-1}$ ($>1 M_\odot$ yr$^{-1}$), we derive H$α$ luminosity functions, which are well described by a Schechter function with $ϕ^* = 10^{-2.85\pm0.03}$ Mpc$^{-3}$ and $L^*_{Hα} = 10^{41.71\pm0.02}$ erg s$^{-1}$ (with a fixed faint end slope $α=-1.35$). We find that surveys probing smaller volumes ($\sim3\times10^4$ Mpc$^3$) are heavily affected by cosmic variance, which can lead to errors of over $100$ per cent in the characteristic density and luminosity of the H$α$ luminosity function. We derive a star formation rate density of $ρ_\mathrm{SFRD} = 0.0094\pm0.0008$ $M_\odot$ yr$^{-1}$, in agreement with the redshift-dependent H$α$ parametrisation from Sobral et al. (2013). The two-point correlation function is described by a single power law $ω(θ) = (0.159\pm0.012) θ^{(-0.75\pm0.05)}$, corresponding to a clustering length of $r_0 = 3.3\pm0.8$ Mpc/h. We find that the most luminous H$α$ emitters at $z\sim0.2$ are more strongly clustered than the relatively fainter ones. The $L^*_{Hα}$ H$α$ emitters at $z\sim0.2$ in our sample reside in $\sim10^{12.5-13.5}$ $M_\odot$ dark matter haloes. This implies that the most star forming galaxies always reside in relatively massive haloes or group-like environments and that the typical host halo mass of star-forming galaxies is independent of redshift if scaled by $L_\mathrm{Hα}/L^*_{Hα}(z)$, as proposed by Sobral et al. (2010).

description: Abstract: Introduction: The purpose of this study was to examine data from the Johnston County Osteoarthritis (OA) Project for independent associations of educational attainment, occupation and community poverty with tibiofemoral knee OA. Methods: A cross-sectional analysis was conducted on 3,591 individuals (66% Caucasian and 34% African American). Educational attainment (< 12 years or ≥12 years), occupation (non-managerial or not), and Census block group household poverty rate (< 12%, 12 to 25%, > 25%) were examined separately and together in logistic models adjusting for covariates of age, gender, race, body mass index (BMI), smoking, knee injury and occupational activity score. Outcomes were presence of radiographic knee OA (rOA), symptomatic knee OA (sxOA), bilateral rOA and bilateral sxOA. Results: When all three socioeconomic status (SES) variables were analyzed simultaneously, low educational attainment was significantly associated with rOA (odds ratio (OR) = 1.44, 95% confidence interval (CI) 1.20, 1.73), bilateral rOA (OR = 1.43, 95% CI 1.13, 1.81), and sxOA (OR = 1.66, 95% CI 1.34, 2.06), after adjusting for covariates. Independently, living in a community of high household poverty rate was associated with rOA (OR = 1.83, 95% CI 1.43, 2.36), bilateral rOA (OR = 1.56, 95% CI 1.12, 2.16), and sxOA (OR = 1.36, 95% CI 1.00, 1.83). Occupation had no significant independent association beyond educational attainment and community poverty. Conclusions: Both educational attainment and community SES were independently associated with knee OA after adjusting for primary risk factors for knee OA.

description: Abstract Background Anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV) is a systemic autoimmune disease characterized by destructive vascular inflammation. Two prominent ANCA autoantigens are myeloperoxidase (MPO) and proteinase 3 (PR3), and transcription of MPO and PRTN3, the genes encoding the autoantigens, is associated with disease activity. We investigated whether patients with AAV have alterations in histone modifications, particularly those associated with transcriptional activation, at MPO and PRTN3. Results We identified a network of genes regulating histone modifications that were differentially expressed in AAV patients compared to healthy controls. We focused on four genes (EHMT1 and EHMT2, ING4, and MSL1) and found their expression correlated with expression of MPO and PRTN3. Methylation of histone H3K9, catalyzed by EHMT1 and EHMT2 and associated with gene silencing, was most depleted at MPO and PRTN3 in patients with active disease and the highest MPO and PRTN3 expression. Acetylation of histone H4K16, modified by complexes containing ING4 and MSL1 and associated with gene activation, was most enriched at MPO and PRTN3 in patients with active disease and the highest MPO and PRTN3 expression. Methylation at H3K4, a mark of transcriptional activation, was enriched at MPO and PRTN3 in patients and healthy controls. Conclusions MPO and PRTN3 in neutrophils of AAV patients with active disease have a distinct pattern of histone modifications, which implicates epigenetic mechanisms in regulating expression of autoantigen genes and suggests that the epigenome may be involved in AAV pathogenesis.

description: An evidence-based understanding of visitors’ landscape preferences is important for holistic forest planning and management. In this study, a visual landscape assessment was conducted to 1) determine the locations and recreational value of scenic hotspots (popular locations) and 2) identify the landscape types that visitors most preferred along the Inariyama Trail in the Takao Quasi-National Park in Tokyo by using geotagged visitor employed photography and asking the 60 participants to score their photographs based on five assessment measures. Nine hundred geotagged photographs were collected, and the subsequent hotspot analysis was conducted using a combination of Getis-Ord Gi* statistics in GIS. Analysis of means (ANOM) and analysis of variance (ANOVA) were performed to determine what and how visitors preferred landscapes in the site. The main findings of this study were as follows: 1) seven hotspots, comprising prominent landscape features and spatial changes, were identified, and 2) Prospect and Look-up were the most highly valued landscape types. These results reveal the importance of Look-up views, which have thus far been underrepresented in landscape assessments, and that hotspots are influenced by landscape features as well as spatial changes. Therefore, through the application of GIS technology, this study lays a foundation for future research as well as the planning and management of forested landscapes that harmonize recreation and other uses.
A new and trivial CP symmetry for extended $A_4$ flavor

Publisher: name: arXiv
Year: 2016
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The combination of $ν_μ$-$ν_τ$ exchange together with CP conjugation in the neutrino sector (known as $\mathrm{CP}^{μτ}$ symmetry or $μτ$-reflection) is known to predict the viable pattern: $θ_{23}=45^\circ$, maximal Dirac CP phase and trivial Majorana phases. We implement such a CP symmetry as a new CP symmetry in theories with $A_4$ flavor. The implementation in a complete renormalizable model leads to a new form for the neutrino mass matrix that leads to further predictions: normal hierarchical spectrum with lightest mass and $m_{ββ}$ ($0νββ$) of only few meV, and either $ν_1$ or $ν_2$ has opposite CP parity. An approximate $L_μ-L_τ$ symmetry arises naturally and controls the flavor structure of the model. The light neutrino masses are generated by the extended seesaw mechanism with 6 right-handed neutrinos (RHNs). The requirement of negligible one-loop corrections to light neutrino masses, validity of the extended seesaw approximation and not too long-lived BSM states to comply with BBN essentially restricts the parameters of the model to a small region: three relatively light right-handed neutrinos at the GeV scale, heavier neutrinos at the electroweak scale and Yukawa couplings smaller than the electron Yukawa. Such a small Yukawa couplings render these RHNs unobservable in terrestrial experiments.

description: In this thesis, I examine the long-term statistical behaviour of particular random one-dimensional discrete-time dynamical systems. In particular, I study a random expanding Lorenz system and a random contracting Lorenz system, and I show that both display exponential quenched decay of correlations for Hölder observables.I achieve this by using random Young towers, in particular results from [8] and [26]. Specifically, I show that for both random systems, a return partition can be constructed on a suitable base with exponentially decaying tails. I then show that the resulting random Young tower satisfies the usual axioms to give us quenched decay of correlations on the random Young Tower itself, which I then relate back to the original random system.

description: We study the role that both vacuum fluctuations and vacuum entanglement of a scalar field play in identifying the spacetime topology, which is not prescribed from first principles---neither in general relativity or quantum gravity. We analyze how the entanglement and observable correlations acquired between two particle detectors are sensitive to the spatial topology of spacetime. We examine the detector's time evolution to all orders in perturbation theory and then study the phenomenon of vacuum entanglement harvesting in Minkowski spacetime and two flat topologically distinct spacetimes constructed from identifications of the Minkowski space. We show that, for instance, if the spatial topology induces a preferred direction, this direction may be inferred from the dependence of correlations between the two detectors on their orientation. We therefore show that vacuum fluctuations and vacuum entanglement harvesting makes it, in principle, possible to distinguish spacetimes with identical local geometry that differ only in their topology.

description: Super-TinyML aims to optimize machine learning models for de-
ployment on ultra-low-power application domains such as wearable
technologies and implants. Such domains also require conformality,
flexibility, and non-toxicity which traditional silicon-based sys-
tems cannot fulfill. Printed Electronics (PE) offers not only these
characteristics, but also cost-effective and on-demand fabrication.
However, Neural Networks (NN) with hundreds of features —often
necessary for target applications— have not been feasible in PE
because of its restrictions such as limited device count due to its
large feature sizes. In contrast to the state of the art using fully par-
allel architectures and limited to smaller classifiers, in this work we
implement a super-TinyML architecture for bespoke (application-
specific) NNs that surpasses the previous limits of state of the art
and enables NNs with large number of parameters. With the intro-
duction of super-TinyML into PE technology, we address the area
and power limitations through resource sharing with multi-cycle
operation and neuron approximation. This enables, for the first
time, the implementation of NNs with up to 35.9× more features
and 65.4× more coefficients than the state of the art solutions.

This involved both palaeodirection and palaeointensity investigations of samples from sites on the W, S and SE slopes of the volcano. Thermal demagnetization of 3 component IRMs, susceptibility measurements and coercivity analyses have been carried out on one pilot specimen per site in order to identify the magnetic carriers and to estimate the magnetic grain size. The identificatìon of the primary direction of TRM was carried out following very stringent criteria (Incoronato, 1996). Palaeointensities were evaluated using both a modification of the Modified Thellier & Thellier method (McClelland et al., 1996) and the innovatìve microwave technique (Shaw et al., 1999). This study has shown that establishing whether or not different exposures or flows are contemporaneous can be established and, in most, but not all, cases can be undertaken successfully using magnetic information recorded by Vesuvian lavas to define the geomagnetic field direction and intensity at the time of their eruption. It is shown that numerous lava flows, outcropping on the W to S slopes of the volcano, must be associated to a large eruption in AD 1631, confirming some previous studies. A new age for a lava flow, ascribed in literature to the 1697 event, is suggested on the basis of both palaeodirection and palaeointensity investigations. Significantly different properties have been found between microwave and thermal experiments although they showed an exceptional level of agreement for the AD 1631 lava flow. In general the trend the palaeointensity variations was similar to that obtained by thermal processes for the last few centuries from other European, Mediterranean and Near East regions (Aitken et al., 1989).

description: Abstract Background Among patients with HIV infection, depression is the most frequently observed psychiatric disorder. The presence of depressive symptoms and cognitive dysfunction among HIV patients has not been well studied in Sub-Saharan Africa. Initiation of highly active antiretroviral therapy (HAART) may have an effect on the prevalence and the change over time of depression symptoms and cognitive impairment among HIV-positive individuals. Methods We recruited 102 HIV-positive individuals at risk of cognitive impairment who were initiating HAART and 25 HIV-negative individuals matched for age and education. Depression was assessed using the Centre for Epidemiologic Studies Depression Scale (CES-D). Neurocognitive assessment included the International HIV Dementia Scale (IHDS), an 8 test neuropsychological battery and the Memorial Sloan Kettering scale. Assessments were carried out at 0, 3 and 6 months. Results The HIV-positive group had more respondents with CES-D score > 16 than the HIV-negative group at all 3 clinic visits (54%Vs 28%; 36% Vs 13%; and 30% Vs 24% respectively; all p < 0.050 OR 2.86, 95% CI: 1.03, 7.95, p = 0.044). The HIV positive group had higher likelihood for cognitive impairment (OR 8.88, 95% CI 2.64, 29.89, p < 0.001). A significant decrease in the mean scores on the CES-D (p = 0.002) and IHDS (p = 0.001) occurred more in the HIV-positive group when compared to the HIV-negative group. There was no association between clinical Memorial Sloan Kettering score and depression symptoms (p = 0.310) at baseline. Conclusion Depression symptomatology is distinct and common among cognitively impaired HIV patients. Therefore individuals in HIV care should be screened and treated for depression.

description: We show that critical systems of finite size develop a fractal structure in momentum space with anomalous dimension given in terms of the isotherm critical exponent delta of the corresponding infinite system. The associated power laws of transverse momentum correlations, in high-energy nuclear collisions, provide us with a signature of a critical point in strongly interacting matter according to the laws of QCD.

description: We study the series expansion of the tau function of the BKP hierarchy applying the addition formulae of the BKP hierarchy. Any formal power series can be expanded in terms of Schur functions. It is known that, under the condition $τ(x)\neq0$, a formal power series $τ(x)$ is a solution of the KP hierarchy if and only if its coefficients of Schur function expansion are given by the so called Giambelli type formula. A similar result is known for the BKP hierarchy with respect to Schur's Q-function expansion under a similar condition. In this paper we generalize this result to the case of $τ(0)=0$.

Is the closest facility the one actually used? An assessment of travel time estimation based on mammography facilities
Creators: name: Henderson, Louise

description: Abstract Background Characterizing geographic access depends on a broad range of methods available to researchers and the healthcare context to which the method is applied. Globally, travel time is one frequently used measure of geographic access with known limitations associated with data availability. Specifically, due to lack of available utilization data, many travel time studies assume that patients use the closest facility. To examine this assumption, an example using mammography screening data, which is considered a geographically abundant health care service in the United States, is explored. This work makes an important methodological contribution to measuring access—which is a critical component of health care planning and equity almost everywhere. Method We analyzed one mammogram from each of 646,553 women participating in the US based Breast Cancer Surveillance Consortium for years 2005–2012. We geocoded each record to street level address data in order to calculate travel time to the closest and to the actually used mammography facility. Travel time between the closest and the actual facility used was explored by woman-level and facility characteristics. Results Only 35 % of women in the study population used their closest facility, but nearly three-quarters of women not using their closest facility used a facility within 5 min of the closest facility. Individuals that by-passed the closest facility tended to live in an urban core, within higher income neighborhoods, or in areas where the average travel times to work was longer. Those living in small towns or isolated rural areas had longer closer and actual median drive times. Conclusion Since the majority of US women accessed a facility within a few minutes of their closest facility this suggests that distance to the closest facility may serve as an adequate proxy for utilization studies of geographically abundant services like mammography in areas where the transportation networks are well established.

description: In this paper we constrain four alternative models to the late cosmic acceleration in the Universe: Chevallier-Polarski-Linder (CPL), interacting dark energy (IDE), Ricci holographic dark energy (HDE), and modified polytropic Cardassian (MPC). Strong lensing (SL) images of background galaxies produced by the galaxy cluster Abell $1689$ are used to test these models. To perform this analysis we modify the LENSTOOL lens modeling code. The value added by this probe is compared with other complementary probes: Type Ia supernovae (SNIa), baryon acoustic oscillations (BAO), and cosmic microwave background (CMB). We found that the CPL constraints obtained of the SL data are consistent with those estimated using the other probes. The IDE constraints are consistent with the complementary bounds only if large errors in the SL measurements are considered. The Ricci HDE and MPC constraints are weak but they are similar to the BAO, SNIa and CMB estimations. We also compute the figure-of-merit as a tool to quantify the goodness of fit of the data. Our results suggest that the SL method provides statistically significant constraints on the CPL parameters but weak for those of the other models. Finally, we show that the use of the SL measurements in galaxy clusters is a promising and powerful technique to constrain cosmological models. The advantage of this method is that cosmological parameters are estimated by modelling the SL features for each underlying cosmology. These estimations could be further improved by SL constraints coming from other galaxy clusters.
