description: The inhomogeneous Zerilli equation is solved in time-domain numerically with the Chebyshev spectral collocation method to investigate a radial-infall of the point particle towards a Schwarzschild black hole. Singular source terms due to the point particle appear in the equation in the form of the Dirac $δ$-function and its derivative. For the approximation of singular source terms, we use the direct derivative projection method without any regularization. The gravitational waveforms are evaluated as a function of time. We compare the results of the spectral collocation method with those of the explicit second-order central-difference method. The numerical results show that the spectral collocation approximation with the direct projection method is accurate and converges rapidly when compared with the finite-difference method.

description: We have investigated the electromagnetic moments of the tau lepton in $e^{+}e^{-} \rightarrow e^{+}γ^{*} γ^{*} e^{-}\rightarrow e^{+}τ\barτe^{-}$ process at the CLIC. We have obtained 95% confidence level bounds on the anomalous magnetic and electric dipole moments for various values of the integrated luminosity and the center of mass energy. We have shown that the $e^{+}e^{-} \rightarrow e^{+}γ^{*} γ^{*} e^{-}\rightarrow e^{+}τ\barτe^{-}$ process at the CLIC leads to a remarkable improvement in the existing experimental bounds on the anomalous magnetic and electric dipole moments.

description: Double-lined eclipsing binaries allow accurate and direct determination of fundamental parameters such as mass and radius for each component, and they provide important constraints on the stellar structure and evolution models. In this study, we aim to determine a unique set of binary parameters for the Algol system W UMi and to examine its evolutionary status. New high-resolution time-series spectroscopic observations were carried out during 14 nights from April 2008 to March 2011, and a total of 37 spectra were obtained using the Bohyunsan Optical Echelle Spectrograph. We measured the radial velocities (RVs) for both components, and the effective temperature of the primary star was found to be $T_{\rm eff,1}$ = 9310 $\pm$ 90 K by a comparison of the observed spectra and the Kurucz models. The physical parameters of W UMi were derived by an analysis of our RV data together with the multi-band light curves of Devinney et al. (1970). The individual masses, radii, and luminosities of both components are $M_1$ = 3.68 $\pm$ 0.10 M$_\odot$ and $M_2$ = 1.47 $\pm$ 0.04 M$_\odot$, $R_1$ = 3.88 $\pm$ 0.03 R$_\odot$ and $R_2$ = 3.13 $\pm$ 0.03 R$_\odot$, and $L_1$ = 102 $\pm$ 1 L$_\odot$ and $L_2$ = 7.3 $\pm$ 0.1 L$_\odot$, respectively. A comparison of these parameters with theoretical stellar models showed that the primary component lies in the main-sequence band, while the less massive secondary is noticeably evolved. The results indicate that the initially more massive star became the present secondary by losing most of its own mass via mass transfer to the companion (present primary).

description: ZF is a well investigated impredicative constructive version of Zermelo-Fraenkel set theory. Using set terms, we axiomatize IZF with Replacement, which we call \izfr, along with its intensional counterpart \iizfr. We define a typed lambda calculus $\li$ corresponding to proofs in \iizfr according to the Curry-Howard isomorphism principle. Using realizability for \iizfr, we show weak normalization of $\li$. We use normalization to prove the disjunction, numerical existence and term existence properties. An inner extensional model is used to show these properties, along with the set existence property, for full, extensional \izfr.

description: Caching is a popular technique for reducing both server load and user response time in distributed systems. We consider the question of whether caching might be effective for search engines as well. We study two real search engine traces by examining query locality and its implications for caching. Our trace analysis produced three results. One result shows that queries have significant locality, with query frequency following a Zipf distribution. Very popular queries are shared among different users and can be cached at servers or proxies, while 16% to 22% of the queries are from the same users and should be cached at the user side. Multiple-word queries are shared less and should be cached mainly at the user side. Another result shows that if caching is to be done at the user side, short-term caching for hours is enough to cover query temporal locality, while server/proxy caching should use longer periods, such as days. The third result showed that most users have small lexicons when submitting queries. Frequent users who submit many search requests tend to reuse a small subset of words to form queries. Thus, with proxy or user side caching, prefetching based on the user lexicon looks promising.

description: Abstract: "A sense of vision is a prerequisite for a robot to function in an unstructured environment. However, real-world scenes contain many interacting phenomena that lead to complex images which are difficult to interpret automatically. Typical computer vision research proceeds by analyzing various effects in isolation (e.g. shading, texture, stereo, defocus), usually on images devoid of realistic complicating factors. This leads to specialized algorithms which fail on real-world images. Part of this failure is due to the dichotomy of useful representations for these phenomena.Some effects are best described in the spatial domain, while others are more naturally expressed in frequency. In order to resolve this dichotomy, we present the combined space/frequency representation which, for each point in an image, shows the spatial frequencies at that point. Within this common representation, we develop a set of simple, natural theories describing phenomena such as texture, shape, aliasing and lens parameters. We show how these theories lead to algorithms for shape from texture and for dealiasing image data. The space/frequency representation should be a key aid in untangling the complex interaction of phenomena in images, allowing automatic understanding of real-world scenes."

description: Kaposi's sarcoma-associated herpesvirus (KSHV) and Epstein–Barr virus (EBV) are prevalent in sub-Saharan Africa, together with HIV; the consequent burden of disease is grave. The cofactors driving transmission of the two viruses and pathogenesis of associated malignancies are not well understood. We measured KSHV and EBV DNA in whole blood and saliva as well as serum antibodies levels in 175 Cameroonians with Kaposi's sarcoma and 1,002 age- and sex-matched controls with and without HIV. KSHV seroprevalence was very high (81%) in controls, while EBV seroprevalence was 100% overall. KSHV DNA was detectable in the blood of 36–46% of cases and 6–12% of controls; EBV DNA was detected in most participants (72–89%). In saliva, more cases (50–58%) than controls (25–28%) shed KSHV, regardless of HIV infection. EBV shedding was common (75–100%); more HIV+ than HIV− controls shed EBV. Cases had higher KSHV and EBV VL in blood and saliva then controls, only among HIV+ participants. KSHV and EBV VL were also higher in HIV+ than in HIV− controls. Cases (but not controls) were more likely to have detectable KSHV in blood if they also had EBV, whereas shedding of each virus in saliva was independent. While EBV VL in saliva and blood were modestly correlated, no correlation existed for KSHV. Numerous factors, several related to parasitic coinfections, were associated with detection of either virus or with VL. These findings may help better understand the interplay between the two gammaherpesviruses and generally among copathogens contributing to cancer burden in sub-Saharan Africa.

description: Statement of the problem: Human papillomavirus (HPV) infection is known to contribute to cervical carcinogenesis, yet other cofactors that may contribute to oncogenesis are poorly understood. Herein, we examine whether the Epstein-Barr virus (EBV) and human cytomegalovirus (CMV), two oncomodulatory viruses, are associated with HPV-mediated cervical neoplastic progression. Methods: Sixty patient cervical brush samples from a study of North Carolina women were obtained. HPV RNA positivity was determined by Aptima testing (Hologic Corporation, Marlborough, MA). The level of viral transcripts for EBV and CMV was quantified (reverse transcription polymerase chain reaction analysis), and the coinfection status with HPV was then compared with the patient's cervical cytology grade. Results: Over one-third (38.3%) of the study population was CMV positive, whereas 43.3% was EBV positive. When sample data were stratified by the cytology grade, 36.5% (19/52) of normal patients, 75% (3/4) of low-grade squamous intraepithelial lesions (LSIL), and 100% (4/4) of patients with high-grade SIL (HSIL) were EBV positive. Conversely, 35.2% (18/52) of normal patients, 25% (1/4) of patients with LSIL, and 50% (2/4) of patients with HSIL were CMV positive. When examining only HPV positive–associated HSIL, 100% (4/4) were positive for both HPV and EBV detection. This suggests that co-viral detection with HPV and EBV is associated with more advanced HSIL cervical lesions, while CMV displayed no clear association with a higher grade of cervical cytology. Conclusions: Co-viral detection with EBV may increase the oncogenicity and/or serve as a viral marker of progression to HPV-associated high-grade cervical dysplasia.

description: We study a non-thermal scenario in a two-Higgs doublet extension of the standard model (SM), augmented by an U(1)_{\rm B-L} gauge symmetry. In this set up, it is shown that the decay product of a weakly coupled scalar field just above the electroweak scale can generate visible and dark matter (DM) simultaneously. The DM is unstable because of the broken B-L symmetry. The lifetime of DM (\approx 5\times 10^{25} sec) is found to be much longer than the age of the Universe, and its decay to the SM leptons at present epoch can explain the positron excess observed at the AMS-02. The relic abundance and the direct detection constraint from Xenon-100 can rule out a large parameter space just leaving the $B-L$ breaking scale around \approx 2 - 4 TeV.

description: The majority of photoelectrochemical (PEC) water splitting cells cannot drive the overall water splitting reactions without the assistance of an external power source. To provide added power, the cells are usually connected to photovoltaic (PV) devices in a tandem arrangement. This approach suffers from severe disadvantages since the PEC cell is connected in series to the PV cell and the overall current is typically limited by the saturation current of the PEC component. Thus, the operating point of the PV cell is often far from optimal and the overall system efficiency tends to be low. We propose a multi-terminal hybrid PV and PEC system (HPEV). As in tandem arrangements, the PEC cell is optically connected in series with the PV cell. However, a second back contact is used to extract the PV cell surplus current and allow parallel production of both electrical power and chemical fuel. Devices consisting of three-terminal silicon photovoltaic cells coupled to titanium dioxide water splitting layers are simulated and fabricated. The cells are shown to produce electricity with little reduction in the water splitting current, surpass the current mismatch limits, and increase the overall system efficiency.

description: OBJECTIVE:To estimate whether targeted educational interventions can increase human papillomavirus (HPV) vaccine acceptability and knowledge among young women.METHODS:An exploratory phase of the study was conducted to determine baseline acceptance of the prophylactic HPV vaccine and barriers to acceptance. Based on the results of that phase of the study, a randomized controlled trial of women aged 12-26 at a single institution was completed. A sample size of at least 84 women in each of three study arms (control, educational handout, or educational video) was planned to detect a 20% difference in vaccine acceptability among arms. All participants completed a survey collecting data on demographics, HPV vaccine preferences, and HPV vaccine knowledge after completion of their randomization assignments. The primary outcome was HPV vaccine acceptability. The secondary outcome was HPV vaccine knowledge.RESULTS:From March 2017 through August 2017, 256 women were randomized to one of three study arms: control (n=85), educational handout (n=84), or educational video (n=87). Demographics were similar between study arms. Overall, 51.7% of participants in the educational video arm reported willingness to accept the HPV vaccine compared with 33.3% and 28.2% of participants in the educational handout and control arms, respectively (P<.01). Those in the educational video and handout arms had higher median HPV vaccine knowledge scores than those in the control arm (6 and 5 vs 3, P<.01). Both interventions were reported as helpful in learning (97.7% vs 92.9%, P=.15), but the educational video arm was more likely to be helpful in deciding on vaccination (86.2% vs 70.2%, P<.01).CONCLUSION:Targeted educational interventions increase HPV vaccine acceptability and knowledge among young women. Follow up studies are needed to determine whether these interventions also increase rates of vaccine uptake and series completion.CLINICAL TRIAL REGISTRATION:Clinicaltrials.gov, NCT03337269.

description: A model of music listening has been automated. A program takes digital audio as input, for example from a compact disc, and outputs an explanation of the music in terms of repeated sections and the implied structure. For example, when the program constructs an analysis of John Coltrane’s “Naima,” it generates a description that relates to the AABA form and notices that the initial AA is omitted the second time. The algorithms are presented and results with two other input songs are also described. This work suggests that music listening is based on the detection of relationships and that relatively simple analyses can successfully recover interesting musical structure.

description: Background: Women with HIV face an increased risk of human papillomavirus (HPV) acquisition and persistence, cervical intraepithelial neoplasia, and invasive cervical cancer. Our objective was to determine the cost-effectiveness of different cervical cancer screening strategies among women with HIV in South Africa. Methods: We modified a mathematical model of HPV infection and cervical disease to reflect coinfection with HIV. The model was calibrated to epidemiologic data from HIV-infected women in South Africa. Clinical and economic data were drawn from incountry data sources. The model was used to project reductions in the lifetime risk of cervical cancer and incremental costeffectiveness ratios (ICERs) of Pap and HPV DNA screening and management algorithms beginning at HIV diagnosis, at 1-, 2-, or 3-year intervals. Strategies with an ICER below South Africa's 2016 per capita gross domestic product (US$5270) were considered "cost-effective." Results: HPV testing followed by treatment (test-and-treat) at 2-year intervals was the most effective strategy that was also cost-effective, reducing lifetime cancer risk by 56.6% with an ICER of US$3010 per year of life saved. Other cost-effective strategies included Pap (referral threshold: HSIL+) at 1-, 2-, and 3-year intervals, and HPV test-and-treat at 3-year intervals. Pap (ASCUS+), HPV testing with 16/18 genotyping, and HPV testing with Pap or visual triage of HPV-positive women were less effective and more costly than alternatives. Conclusions: Considering per capita gross domestic product as the benchmark for cost-effectiveness, HPV test-and-treat is optimal in South Africa. At lower cost-effectiveness benchmarks, Pap (HSIL+) would be optimal.

description: We present a construction of subspace codes along with an efficient algorithm for list decoding from both insertions and deletions, handling an information-theoretically maximum fraction of these with polynomially small rate. Our construction is based on a variant of the folded Reed-Solomon codes in the world of linearized polynomials, and the algorithm is inspired by the recent linear-algebraic approach to list decoding. Ours is the first list decoding algorithm for subspace codes that can handle deletions; even one deletion can totally distort the structure of the basis of a subspace and is thus challenging to handle. When there are only insertions, we also present results for list decoding subspace codes that are the linearized analog of Reed-Solomon codes (proposed previously, and closely related to the Gabidulin codes for rank-metric), obtaining some improvements over similar results in previous work.

description: Background: Trichomonas vaginitis (TV) infection has obviously been implicated in gynecological morbidity but still unclear in cervical lesions. Objective: To evaluate the risk of hr-HPV infection and cervical intraepithelial neoplasia grade 2 or worse (CIN2 +) by TV infection. Study design: The pooled study was conducted among 12 population-based, cervical cancer screening studies throughout China (N = 24,054). HPV was detected by Hybrid Capture®2 (HC2) test. Past TV infection was measured by self-reporting, current TV infection was diagnosed by liquid-based cytology (LBC), cervical lesions was diagnosed by histopathology. Results: Respective prevalence of hr-HPV and CIN2+ were 17.4% and 3.3%. Out of 24,054 women, 14.6% reported past TV infection, and out of 11,853 women, 9.9% had current TV infection. Current TV-positive women had an increased risk for hr-HPV (OR 1.31, 95%CI: 1.11-1.56). The risk of CIN2+ decreased for hr-HPV positive women with current TV infection (adjusted OR 0.50, 95% CI: 0.30-0.84) and past TV infection (adjusted OR 0.68, 95% CI: 0.54-0.86). Among hr-HPV negative women, no significant associations were observed between past or current TV infection and risk of CIN2+. Conclusions: Women infected with HPV are more likely to be infected by other types of sexually transmitted diseases. Current TV-positive women had an increased risk for hr-HPV infection compared to currently TV-negative women. Both past and current TV-positive women had a decreased risk for CIN2+, especially among high-risk HPV positive women. More direct investigation into the interaction between TV, HPV, inflammatory signals, and risk of carcinogenesis are further needed.

description: Objectives: Self-collection of cervico-vaginal samples for human papillomavirus (HPV) testing has the potential to make cervical cancer screening more accessible to underscreened women. We evaluated the acceptability and ease of use of home-based HPV self-collection within a diverse population of low-income, infrequently screened women. Methods: Participants were low-income women from North Carolina who had not received Pap testing in 4 or more years. Eligible women received a self-collection kit containing instructions and a brush for home-based sample collection. A total of 227 women returned a self-collected sample by mail and completed a questionnaire to assess their experiences with HPV self-collection. We described acceptability measures and used logistic regression to identify predictors of overall positive thoughts about the self-collection experience. Results: Nearly all women were willing to perform HPV self-collection again (98%) and were comfortable receiving the self-collection kit in the mail (99%). Overall, 81% of participants reported positive thoughts about home-based self-collection. Women with at least some college education and those who were divorced, separated or widowed were more likely to report overall positive thoughts. Aspects of self-collection that participants most commonly reported liking included convenience (53%), ease of use (32%) and privacy (23%). The most frequently reported difficulties included uncertainty that the self-collection was done correctly (16%) and difficulty inserting the self-collection brush (16%). Conclusions: Home-based self-collection for HPV was a highly acceptable screening method among low-income, underscreened women and holds the promise to increase access to cervical cancer screening in this high-risk population.

description: The main goal of our study was investigation of the influence of the deformations (sufficiently large for the establishing the non-zero gap) on electrotransport properties of impure graphene. To achieve this purpose, we implemented the simulation package that allows to perform numerical calculation of the conductivity and mobility of graphene samples subjected to two types of the uniaxial strain: along zigzag and armchair edges. All numerical calculations are performed within the Kubo-Greenwood methodology along with a tight-binding model. Transport properties are studied in case of a presence of impurity atoms described by the weak short-range scattering potential. Various deformation values are considered. The uniaxial strain acts as an additional source of the electron scattering, herewith, can strongly affect both mobility and conductivity of graphene and introduce anisotropy of its electron transport properties.

description: The differential energy spectrum of cosmic rays from Cherenkov radiation measurements in EAS in the energy range of 10^15-10^20eV has been compared with an anomalous diffusion model for the particles in interstellar space having fractal properties (Lagutin et al, 2001). The close association between experimental data and calculated "all particle" spectra in form at E(0) (10^15-10^18)eV is found. In this case, the average mass composition of cosmic rays calculated by five components does not contradict the average mass composition from experimental data which was obtained by several of EAS characteristics in that energy region.

description: Objectives Self-collection of samples for human papillomavirus (HPV) testing (self-collection) has the potential to increase cervical cancer screening among underscreened women. We assessed attitudes toward at-home HPV self-collection compared with clinic-based Pap testing in this higher-risk population. Materials and Methods Participants were low-income women in North Carolina overdue for cervical cancer screening. Women self-collected samples at home, returned samples by mail for HPV testing, and completed phone questionnaires about at-home HPV self-collection. Participants were referred to clinic-based Pap testing and invited to complete a second questionnaire about Pap testing. A cross-sectional questionnaire compared attitudes, experiences, and preferences for self-collection versus Pap testing and assessed predictors of preference for HPV self-collection. Results Half (51%) of 221 women reported a preference for HPV self-collection, 19% preferred Pap testing, and 27% reported no preference. More women reported difficulty finding time to do the Pap test (31%) than the self-test (13%, p =.003) and being afraid of the self-test results (50%) than the Pap test results (36%, p =.02). There were relatively fewer reports of physical discomfort and pain from self-collection than Pap testing (discomfort: 18% self; 48% Pap; pain: 8% self; 30% Pap, p =.001). No differences were found in positive versus negative thoughts about the tests, trust in the tests' safety and accuracy, or willingness to do tests again. Conclusions Overall positive attitudes toward HPV self-collection compared with Pap testing among underscreened women suggest that self-collection is a promising option to increase cervical cancer screening in this high-risk population.

description: We develop an analytical mode-matching technique for the tight-binding model to describe electron transport across graphene P-N junctions. This method shares the simplicity of the conventional mode-matching technique for the low-energy continuum model and the accuracy of the tight-binding model over a wide range of energies. It further reveals an interesting phenomenon on a sharp P-N junction: the disappearance of the well-known Klein tunneling (i.e., perfect transmission) at normal incidence and the appearance of perfect transmission at oblique incidence due to trigonal warping at energies beyond the linear Dirac regime. We show that this phenomenon arises from the conservation of a generalized pseudospin in the tight-binding model. We expect this effect to be experimentally observable in graphene and other Dirac fermions systems, such as the surface of three-dimensional topological insulators.

description: Motivated by the search for geometric observables in nonperturbative quantum gravity, we define a notion of coarse-grained Ricci curvature. It is based on a particular way of extracting the local Ricci curvature of a smooth Riemannian manifold by comparing the distance between pairs of spheres with that of their centres. The quantum Ricci curvature is designed for use on non-smooth and discrete metric spaces, and to satisfy the key criteria of scalability and computability. We test the prescription on a variety of regular and random piecewise flat spaces, mostly in two dimensions. This enables us to quantify its behaviour for short lattices distances and compare its large-scale behaviour with that of constantly curved model spaces. On the triangulated spaces considered, the quantum Ricci curvature has good averaging properties and reproduces classical characteristics on scales large compared to the discretization scale.

description: Objective The aim of the study was to evaluate the performance of the HPV-HR test to detect high-risk human papillomavirus (HPV) in urine samples in comparison with a commercial molecular HPV test. Materials and Methods This is a prospective study, in which 350 patients diagnosed previously with cervical intraepithelial neoplasia (CIN) grade 2 or higher were enrolled. Urine and cervical specimens were collected. Urine was tested with the HPV-HR test and cervical specimens were tested with the Cobas. Results Of the 336 evaluable patients, there were 271 cases of CIN 2+, of which 202 were CIN 3+ and the remaining 65 patients were less than CIN 2. Positivity was 77.1% (95% confidence interval [CI] = 72.5-81.5) for the urine samples and 83.6% (95% CI = 79.6-87.6) for the cervical samples. Agreement between cervical and urine samples for HPV detection was 79.8% (κ = 0.363; 95% CI = 0.243-0.484). Sensitivity for CIN 2+ was 83.4% (95% CI = 78.4-87.6) for urine and 90.8% (95% CI = 86.7-92.9) for cervical samples. The sensitivity for CIN 3+ was 85.6% (95% CI = 80.0-90.2) for urine and 92.6% (95% CI = 88.0-95.8) for cervical samples. Specificity for worse than CIN 2 was 50.8% (95% CI = 33.7-59.0) and 46.2% (95% CI = 33.7-59.0) for urine and cervical samples, respectively. Conclusions Although these results demonstrated slightly higher detection rates for HR-HPV and clinical sensitivity in cervical samples than in urine, when compared with histological diagnoses, urine sampling is a viable alternative to access women who do not participate in routine screening programs.

description: Automated market makers are algorithmic agents that provide liquidity in electronic markets. A recent stream of research in automated market making is the design of liquidity-sensitiveautomated market makers, which are able to adjust their price response to the level of active interest in the market. In this paper, we introduce homogeneous risk measures, the general class of liquidity-sensitive automated market makers, and show that members of this class are (necessarily and sufficiently) the convex conjugates of compact convex sets in the non-negative orthant. We discuss the relation between features of this convex conjugate set and features of the corresponding automated market maker in detail, and prove that it is the curvature of the convex conjugate set that is responsible for implicitly regularizing the price response of the market maker. We use our insights into the dual space to develop a new family of liquidity-sensitive automated market makers with desirable properties.

description: An intelligent robot agent based on domain ontology, machine learning mechanism, and Fuzzy Markup Language (FML) for students and robot co-learning is presented in this paper. The machine-human co-learning model is established to help various students learn the mathematical concepts based on their learning ability and performance. Meanwhile, the robot acts as a teacher's assistant to co-learn with children in the class. The FML-based knowledge base and rule base are embedded in the robot so that the teachers can get feedback from the robot on whether students make progress or not. Next, we inferred students' learning performance based on learning content's difficulty and students' ability, concentration level, as well as teamwork sprit in the class. Experimental results show that learning with the robot is helpful for disadvantaged and below-basic children. Moreover, the accuracy of the intelligent FML-based agent for student learning is increased after machine learning mechanism.

description: Previously it has been shown that imposing a Petrov-like boundary condition on a hypersurface may reduce the Einstein equation to the incompressible Navier-Stokes equation, but all these correspondences are established in the near horizon limit. In this note, we remark that this strategy can be extended to an arbitrary finite cutoff surface which is spatially flat, and the Navier-Stokes equation is obtained by employing a non-relativistic long-wavelength limit.

description: Study Objective: To assess adolescent health care providers’ recommendations for, and attitudes towards human papillomavirus (HPV) vaccination in 5 countries. Design: In-depth interviews of adolescent health care providers, 2013-2014. Setting: Five countries where HPV vaccination is at various stages of implementation into national programs: Argentina, Malaysia, South Africa, South Korea, and Spain. Participants: Adolescent health care providers (N = 151) who had administered or overseen provision of adolescent vaccinations (N = Argentina: 30, Malaysia: 30, South Africa: 31, South Korea: 30, Spain: 30). Main Outcome Measures: Frequency of HPV vaccination recommendation, reasons providers do not always recommend the vaccine and facilitators to doing so, comfort level with recommending the vaccine, reasons for any discomfort, and positive and negative aspects of HPV vaccination. Results: Over half of providers 82/151 (54%) recommend HPV vaccination always or most of the time (range: 20% in Malaysia to 90% in Argentina). Most providers 112/151 (74%) said they were comfortable recommending HPV vaccination, although South Korea was an outlier 10/30 (33%). Providers cited protection against cervical cancer 124/151 (83%) and genital warts 56/151 (37%) as benefits of HPV vaccination. When asked about the problems with HPV vaccination, providers mentioned high cost 75/151 (50% overall; range: 26% in South Africa to 77% in South Korea) and vaccination safety 28/151 (19%; range: 7% in South Africa to 33% in Spain). Free, low-cost, or publicly available vaccination 59/151 (39%), and additional data on vaccination safety 52/151 (34%) and efficacy 43/151 (28%) were the most commonly cited facilitators of health provider vaccination recommendation. Conclusion: Interventions to increase HPV vaccination should consider a country's specific provider concerns, such as reducing cost and providing information on vaccination safety and efficacy.

description: We observed the quasar PG1211+143 using the Cosmic Origins Spectrograph on the Hubble Space Telescope in April 2015 as part of a joint campaign with the Chandra X-ray Observatory and the Jansky Very Large Array. Our ultraviolet spectra cover the wavelength range 912-2100 A. We find a broad absorption feature (~1080 km/s) at an observed wavelength of 1240 A. Interpreting this as HI Ly alpha, in the rest frame of PG1211+143 (z=0.0809), this corresponds to an outflow velocity of -16,980 km/s (outflow redshift z_out ~ -0.0551), matching the moderate ionization X-ray absorption system detected in our Chandra observation and reported previously by Pounds et al. (2016). With a minimum HI column density of log N_HI > 14.5, and no absorption in other UV resonance lines, this Ly alpha absorber is consistent with arising in the same ultra-fast outflow as the X-ray absorbing gas. The Ly alpha feature is weak or absent in archival ultraviolet spectra of PG1211+143, strongly suggesting that this absorption is transient, and intrinsic to PG1211+143. Such a simultaneous detection in two independent wavebands for the first time gives strong confirmation of the reality of an ultra-fast outflow in an active galactic nucleus.
