description: Influenza immunization coverage rates remains far below the optimal value recommended by World Health Organization, even in groups considered  more at risk, as elderly. A possible explanation of lacking compliance to vaccine uptake can rely on deprivation. A local deprivation index, specifically developed, was proposed for the classification of the residents in Ferrara’s municipality in order to evaluate the characteristics of over 65 people accepting/refusing the influenza immunization (2010-2015). The variables involved in the Ferrara’s deprivation index were primarily related to demographic aspects like age, being widow/widower, education, composition of the family and characteristics of the house. In groups with higher deprivation, elderly were more frequent (53.4% in very deprived). Influenza immunization coverage rates were unsatisfactory in all categories of deprivation. A decreasing trend in coverage rates with decreasing deprivation was observed with statistical significance, in general population and in males but not in females. In addition to factors composing the local deprivation index, being separated, living in a family of three members and working as independent contractor were features preventing from the immunization in very deprived elderly.

description: Abstract

 Introduction

Inequality levels are associated with vaccination coverage among the older and at risk population hypothesizing socio-economic status (SES) as a determinant of health status.

The aim of the study was to evaluate the trend of health outcome and socio-health-economic-status deprivation index (IDPA) among elderly people in Palermo city, Italy .

 Methods

The Palermo Unit of 2015 CCM project deal with collection of data useful to validate IDPA using the Italian census data from 2009 to 2015 on overall mortality and cause of death. The preventive outcome used to validate the IDPA index was vaccination coverage from 2009-2010 to 2014-2015 influenza season among Palermo elderly population.

 Results

Among the elderly IDPA had a significantly decreasing trend in overall mortality (p <0.05) and a significant increasing trend of mortality due to influenza or pneumonia (p <0.05) with higher deprivation index.

Comparing vaccination coverage with deprivation levels, a linear trend between coverage rates increase and deprivation index decrease (p <0.05) was observed, with an overall 27% vaccination coverage among the older people. Elderly population of Palermo living in a census context with more regular migrant, divorced and single-parent families were more hesitant to the execution of influenza vaccination.

 Conclusions

This study allowed to identify the elderly population groups with lower influenza vaccination adherence to which could be addressed health promotion interventions in order to facilitate the "healthy aging".

description: The aim of the present study was to evaluate the relationship between social deprivation indices and anti-influenza vaccine coverage in the Sardinian elderly population (over 65yearsold).

This relationship was firstly observed in a regional context. An already-known deprivation index was used, and its trivial relationship with the anti-influenza vaccine coverage was evaluated. Secondly, the same relationship was assessed for the homogeneous area of the Municipality of Sassari. This required adoption of an ad hoc deprivation index, which allowed us to stratify the population into deprivation groups and to correlate the vaccine coverage to socio-economic variables.

Results showed that the regional anti-influenza vaccine coverage linearly increased with the decrease in the deprivation. This trend was confirmed for the Municipality of Sassari. Pearson's analysis highlighted factors that significantly correlate to vaccine coverage.

In Sardinia, the relationship between anti-influenza vaccination coverage and socio-economic health status was consistent with the international panorama, therefore highlighting the necessity to arrange interventions to promote vaccination coverage in the elderly population.

description: Objective

The aim of this paper is to describe the results obtained from the application of a specific local deprivation index, calculated on the basis of 2011 Census sections, to general and cause-specific mortality and influenza vaccination coverage among elderly people of the municipality of Florence.

Methods

General and cause-specific mortality data (2009-2013) and influenza vaccination coverage data (2015/16 and 2016/17) have been collected for subjects aged ≥65 years residing in the municipality of Florence (Tuscany), at the 2011 Census section level. Socio-Economic and Health Deprivation Index (SEHDI) has been constructed and validated by using socio-economic indicators and mortality ratios.

Results

Half the Florence population belongs to the medium deprivation group; about 25% belongs to the two most deprived groups, and the remaining 25% is wealthy. Elderly people mostly belong to the high deprivation group. All-cause mortality and cause-specific mortality (cancer and respiratory diseases) reach the highest values in the high deprivation group.Influenza vaccination coverage (VC) is 54.7% for the seasons 2015/16 and 2016/17, combined. VC shows a growing linear trend as deprivation increases. VC appears to be correlated with different factors in the different deprivation groups.

Conclusions
Socio-economic deprivation plays an important role in health choices, so the application of SEHDI allows to identify the characteristics of the main sub-groups of the population with a low adherence to influenza vaccination. Results of the present study should be spread to General Practitioners in order to help them to promote influenza vaccination to their patients.

description: We present measurements of 5-25 μm emission features of brightest cluster galaxies (BCGs) with strong optical emission lines in a sample of 9 cool-core clusters of galaxies observed with the Infrared Spectrograph on board the Spitzer Space Telescope. These systems provide a view of dusty molecular gas and star formation, surrounded by dense, X-ray emitting intracluster gas. Past work has shown that BCGs in cool-core clusters may host powerful radio sources, luminous optical emission line systems, and excess UV, while BCGs in other clusters never show this activity. In this sample, we detect polycyclic aromatic hydrocarbons (PAHs), extremely luminous, rotationally-excited molecular hydrogen line emission, forbidden line emission from ionized gas ([Ne II] and [Ne III]), and infrared continuum emission from warm dust and cool stars. We show here that these BCGs exhibit more luminous forbidden neon and H2 rotational line emission than star-forming galaxies with similar total infrared luminosities, as well as somewhat higher ratios of 70 μm / 24 μm luminosities. Our analysis suggests that while star formation processes dominate the heating of the dust and PAHs, a heating process consistent with suprathermal electron heating from the hot gas, distinct from star formation, is heating the molecular gas and contributing to the heating of the ionized gas in the galaxies. The survival of PAHs and dust suggests that dusty gas is somehow shielded from significant interaction with the X-ray gas.

description: Introduction

Elderly people are more likely to develop influenza-related complications, but despite the recommendations, the optimal vaccination coverage is not reached. The use of deprivation indices can help identifying subgroups with lower vaccine uptake. We analyzed vaccination coverage of elderly living in the city of Rome based on their socioeconomic characteristics using a local deprivation index.

Methods

We focused on population ≥65 years living in the city of Rome from 2009 to 2013. Information about vaccination coverage was collected from general practitioners. A combination of multivariate techniques, including multiple linear regression, factor and cluster analysis, was used to construct a composite area-based deprivation index. The index was calculated for each census tract, based on data from the 2001 Italian census.

Results

The majority of elderly living in the city of Rome belonged to the medium (40.4%) and medium-high (24%) deprivation groups, and only 4.5% of the population was in the low deprivation group. An inverse relationship was found between influenza vaccination coverage and deprivation index: elderly from low deprivation group had lower coverage (55.45%) in respect to high deprivation group (57.59%). In particular, vaccination coverage decreased with the increase of replacement index, employment rate and the percentage of: singles, divorced; graduates and higher school graduates; employed, entrepreneurs and freelancers, family assistants, students; foreigners and stateless persons residing in Italy; families of one person.

Conclusions

Our results show an inverse relationship between deprivation and vaccination coverage and may help identifying subgroups that could benefit from targeted initiatives to increase vaccination coverage.

The fibers are assumed to share the load equally, and to obey Hookean elasticity up to the breaking point. The bundle is slightly overloaded, which leads to complete failure. We study the properties of emission bursts in which an amount of energy $E$ is released. The analysis shows that the size of the energy bursts has a minimum when the system is half-way from the collapse point.

description: Introduction

In Italy, vaccination against seasonal influenza has been recommended for the elderly since 1980, but coverage is still far below the WHO minimum target level of 75%. Effective interventions to improve influenza vaccination should understand which socioeconomic determinants may cause inequalities in vaccine uptake. This study aimed at assessing differences in vaccination coverage among people ≥65 years of age residing in the Foggia municipality, Italy, by socioeconomic status.

Methods

A Socio-Economic-Health Deprivation Index (SEHDI) was constructed using a multivariate analysis model. Resident population, for census block, was classified in 5 deprivation groups. Differences in demographic and socioeconomic indicators, the standardized mortality ratios (SMRs), and the average vaccination coverage among deprivation groups were evaluated with the linear F-test. The association between census variables and influenza vaccination coverage, in each deprivation group, was assessed using the Pearson bivariate correlation.

Results

The SEHDI allowed to identify factors related to ageing, housing, household size and composition, and education. Forty percent of people residing in the Foggia municipality lived in conditions of socioeconomic and health deprivation. Belonging to families with 3 or 4 members was associated with increased coverage rates. In the most deprived group, vaccination uptake was positively associated with the dependency ratio.

Conclusions

The results of this study have shown that there is still large room for improving influenza vaccination coverage among subjects belonging to the most deprived areas. Surveillance of trends in influenza vaccine uptake by socioeconomic groups is a feasible contribution to implementing effective, tailored to the frail older persons, vaccine utilization programs.

description: For the one-dimensional Holstein model, we show that the relations among the scaling exponents of various correlation functions of the Tomonaga Luttinger liquid (LL), while valid in the thermodynamic limit, are significantly modified by finite size corrections. We obtain analytical expressions for these corrections and find that they decrease very slowly with increasing system size. The interpretation of numerical data on finite size lattices in terms of LL theory must therefore take these corrections into account. As an important example, we re-examine the proposed metallic phase of the zero-temperature, half-filled one-dimensional Holstein model without employing the LL relations. In particular, using quantum Monte Carlo calculations, we study the competition between the singlet pairing and charge ordering. Our results do not support the existence of a dominant singlet pairing state.

description: Introduction
Elderly use to develop more complications after influenza and the 90% of deaths for influenza regards them. Indeed, they are among the major target of vaccination campaigns. The use of deprivation indices can help to identify subgroups with lower vaccine uptake. This work was aimed to analyze vaccination coverage of elderly living in Genoa using a local Index of Socio-Economic and Health Deprivation (SEHDI) in order to identify subgroups of population needing specific actions to improve vaccination coverage.
Methods
The target population was the population aged ≥65 years living in Genoa in the 2009-2013 period. Information about vaccination coverage derived from general practitioners. A combination of linear regression, factor analysis and cluster analysis was used to build the SEHDI at Census Tract (CT) level, deriving data from the 2011 Italian census.
Results
In Genoa, in 2011, people aged ≥65 years represented the 27.7% of the population. The majority of elderly belonged to medium (45.3%) and medium-high (32%) deprivation groups, while the percentages in the extreme tails were low (3.6% high deprived; 1.3% low deprived). Significant not linear (p<0.05 NL) relationships were observed in both sexes for all respiratory diseases (RD) and COPD mortality, with the highest SMRs values in the high deprivation group of women (1.81, p<0.05 RD; 1.79, p<0.05 COPD). The SMRs for influenza and pneumonia showed a linear positive trend in women (p<0.05), with the highest value in the high deprived (1.97, p<0.05), while in men the trend was NL (p<0.05). A positive linear trend (p<0.05) was found for vaccination coverage, weakly growing at deprivation increase until the medium-high deprived group (from 34.6% to 44.4%), but the high deprivation group showed the lowest value (33,3%).
Conclusions
The results displayed a positive relationship between deprivation and vaccination coverage. This finding should be taken into account in the organization of vaccination campaigns and should call for differentiated actions in each small areas.

description: It is shown that effective quantum-state and entanglement transfer can be obtained by inducing a coherent dynamics in quantum wires with homogeneous intrawire interactions. This goal is accomplished by tuning the coupling between the wire endpoints and the two qubits there attached, to an optimal value. A general procedure to determine such value is devised, and scaling laws between the optimal coupling and the length of the wire are found. The procedure is implemented in the case of a wire consisting of a spin-1/2 XY chain: results for the time dependence of the quantities which characterize quantum-state and entanglement transfer are found of extremely good quality and almost independent of the wire length. The present approach does not require `ad hoc' engineering of the intrawire interactions nor a specific initial pulse shaping, and can be applied to a vast class of quantum channels.

description: We discuss several steady-state rotation and oscillation modes of the planar parametric rotator and pendulum with damping. We consider a general elliptic trajectory of the suspension point for both rotator and pendulum, for the latter at an arbitrary angle with gravity, with linear and circular trajectories as particular cases. We treat the damped, non-linear equation of motion of the parametric rotator and pendulum perturbatively for small parametric excitation and damping, although our perturbative approach can be extended to other regimes as well. Our treatment involves only ordinary second-order differential equations with constant coefficients, and provides numerically accurate perturbative solutions in terms of elementary functions. Some of the steady-state rotation and oscillation modes studied here have not been discussed in the previous literature. Other well-known ones, such as parametric resonance and the inverted pendulum, are extended to elliptic parametric excitation tilted with respect to gravity. The results presented here should be accessible to advanced undergraduates, and of interest to graduate students and specialists in the field of non-linear mechanics.

description: Because massive, low-metallicity population III (PopIII) stars may produce very powerful long gamma-ray bursts (LGRBs), high-redshift GRB observations could probe the properties of the first stars. We analyze the correlation between early PopIII stars and LGRBs by using cosmological N-body/hydrodynamical simulations, which include detailed chemical evolution, cooling, star formation, feedback effects and the transition between PopIII and more standard population I/II (PopII/I) stars. From the Swift observed rate of LGRBs, we estimate the fraction of black holes that will produce a GRB from PopII/I stars to be in the range 0.0286, becoming as high has 40% at z>10. Finally, we study the properties of the galaxies hosting our sample of GRB3. We find that the average metallicity of the galaxies hosting a GRB3 is typically higher than the critical metallicity used to select the PopIII stars, due to the efficiency in polluting the gas above such low values. We also find that the highest probability of finding a GRB3 is within galaxies with a stellar mass <10^7 Msun, independently from the redshift.

description: This paper reports high resolution simulations using a fifth-order weighted essentially non-oscillatory (WENO) scheme with a third order TVD Runge-Kutta time stepping method to examine the features of detonation front and physics in square ducts. The simulations suggest that two and three-dimensional detonation wave front formations are greatly enhanced by the presence of transverse waves. The motion of transverse waves generates triple points (zones of high pressure and large velocity coupled together), which cause the detonation front to become locally overdriven and thus form "hot spots". The transversal motion of these hot spots maintains the detonation to continuously occur along the whole front in two and three-dimensions. The present simulations indicate that the influence of the transverse waves on detonation is more profound in three dimensions and the pattern of quasi-steady detonation fronts also depends on the duct size. For a narrow duct (4LX4L where L is the half reaction length), the detonation front displays a distinctive "spinning" motion about the axial direction with a well-defined period. For a wider duct (20LX20L), the detonation front exhibits a "rectangular mode" periodically, with the front displaying "convex" and "concave" shapes one following the other and the transverse waves on the four walls being partly out-of-phase with each other.

description: We present Keck Interferometer observations of the three prototypical FU Orionis stars, FU Ori, V1057 Cyg, and V1515 Cyg. With a spatial resolution of a few milli-arcseconds and a spectral resolution of 2000, our near-infrared observations spatially resolve gas and dust emission extending from stellocentric radii of ~0.05 AU to several AU. We fit these data with accretion disk models where each stellocentric radius of the disk is represented by a supergiant-type stellar emission spectrum at the disk temperature. A disk model is consistent with the data for FU Ori, although we require some local asymmetry in the disk. For V1057 Cyg the disk model does not fit our data well, especially compared to the fit quality achieved for FU Ori. We speculate that a disk wind may be contributing substantially to the observed near-IR emission in this source. The data for V1515 Cyg are noisier than the data obtained for the other two objects, and do not strongly constrain the validity of an accretion disk model.

The Swedish film industry was growing rapidly already before the outbreak of the First World War. The number of cinemas increased every year. It is estimated that there were 700 cinemas in Sweden in 1919, twice the amount compared to 1914. Probably because Sweden did not take an active part in the war, it was, with a few noteworthy exceptions, rare that films produced in Sweden commented on the ongoing conflict.

Using millimetre surveys of discs within six local star-formation regions, we confirm this result, and find that only a few percent of young stars have enough circumstellar material to build gas giant planets, in standard core accretion models. Since the frequency of observed exo-planets is greater than this, there is a `missing mass' problem. As alternatives to simply adjusting the conversion of dust-flux to disc mass, we investigate three other classes of solution. Migration of planets could hypothetically sweep up the disc mass reservoir more efficiently, but trends in multi-planet systems do not support such a model, and theoretical models suggest that the gas accretion timescale is too short for migration to sweep the disc. Enhanced inner-disc mass reservoirs are possible, agreeing with predictions of disc evolution through self-gravity, but not adding to millimetre dust-flux as the inner disc is optically thick. Finally, the incidence of massive discs is shown to be higher at the {\it proto}stellar stages, Classes 0 and I, where discs substantial enough to form planets via core accretion are abundant enough to match the frequency of exo-planets. Gravitational instability may also operate in the Class 0 epoch, where half the objects have potentially unstable discs of $\ga$30 % of the stellar mass. However, recent calculations indicate that forming gas giants inside 50 AU by instability is unlikely, even in such massive discs. Overall, the results presented suggest that the canonically 'proto-planetary' discs of Class II T Tauri stars {\bf have globally low masses in dust observable at millimetre wavelengths, and conversion to larger bodies (anywhere from small rocks up to planetary cores) must already have occurred.}

description: The dynamics of electrons in ac driven double quantum dots have been extensively analyzed by means of Floquet theory. In these systems, coherent destruction of tunneling has been shown to occur for certain ac field parameters. In the present work we analyze, by means of Floquet theory, the electron dynamics of a triple quantum dot in series attached to electric contacts, where the central dot position oscillates. In particular, we analyze the quasienergy spectrum of this ac driven nanoelectromechanical system, as a function of the intensity and frequency of the ac field and of external dc voltages. For strong driving fields, we derive, by means of perturbation theory, analytical expressions for the quasienergies of the driven oscillator system. From this analysis we discuss the conditions for coherent destruction of tunneling (CDT) to occur as a function of detuning and field parameters. For zero detuning, and from the invariance of the Floquet Hamiltonian under a generalized parity transformation, we find analytical expressions describing the symmetry properties of the Fourier components of the Floquet states under such transformation. By using these expressions, we show that in the vicinity of the CDT condition, the quasienergy spectrum exhibits exact crossings which can be characterized by the parity properties of the corresponding eigenvectors.

description: As World War I ravaged Europe and the Ottoman military mobilized, Ottoman society sought to make sense of its involvement in the war. Officials, intellectuals, and everyday citizens struggled both to legitimize Ottoman participation and to justify the sacrifices. The near catastrophe of the Balkan Wars had only recently led them to an existential crisis, forcing them to reconsider their role and reimagine the New Ottoman community. Nevertheless, the state apparatus and Ottoman intellectuals, although agreeing to frame war propaganda around Islam, were indecisive as to what kind of national identity would best serve the war effort and the empire. Widespread illiteracy forced the state to rely mainly on oral and visual propaganda, while early drawbacks and the war’s duration convinced many conscripts and civilians alike to trust their own experience to make sense of the war.

Bio-oil upgrading through biodiesel emulsification and catalytic vapour cracking

description: With our limited fuel supplies struggling to keep up with our ever-increasing demand for energy, and the rising trend towards sustainable and cleaner technologies, the need to harness the potential of bio-oil as an alternative source of energy has never been more compelling. Although crude bio-oil can already be utilized to supplement heating oils and boiler fuels, its greater value lies in its potential as a source of transportation fuels and chemicals after upgrading. In collaboration with Diacarbon Energy Inc., the main objectives of this project were twofold: (1) investigating the effect of extraction location from their proprietary pyrolysis unit on crude bio-oil quality prior to its emulsification with biodiesel, and characterizing the resulting biodiesel- and lignin-rich layers; and (2) designing and building a catalytic test unit to perform in situ cracking of slow pyrolysis vapours. Experimental results confirmed that extraction location does affect the crude bio-oil quality. The effect of the surfactant on the emulsification was minimal as the resulting biodiesel-rich layer from the emulsification without the surfactant showed similar improvements in terms of water content, viscosity, TAN and HHV. A water mass balance confirmed that the majority of the water (~97%) is retained in the lignin-rich phase after emulsification. This is significant because the solvency of biodiesel can be utilized to upgrade bio-oils by selectively extracting its desirable fuel components into a biodiesel-rich phase, which can then be easily separated from the lignin- rich phase where the higher molecular weight compounds, such as pyrolytic lignin, as well as the majority of the water, are retained. The bio-oil samples obtained from the non-catalytic and catalytic vapour cracking experiments separated into two distinct layers – an aqueous and organic layer. While the aqueous layers were fairly similar in nature, the organic layer from the catalytic experiment showed a significant decrease in viscosity (94.3% less) and water content (64.3% less). The organic layer from the catalytic pyrolysis remained homogeneous while that from the non-catalytic pyrolysis split into a hazy aqueous layer (with suspended oil droplets) sandwiched between a thin organic layer on top and a thicker organic layer at the bottom.
Influenza vaccination coverage and deprivation among the elderly in the municipality of Cagliari: results and perspectives.

description: Introduction. The elderly are among the main targets of influenza vaccination campaigns. Previous studies have shown that socio-economic status influences compliance with influenza vaccination, particularly in the elderly. Deprivation indices can therefore be useful in identifying population groups with lower vaccination uptake and guide targeted intervention to improve vaccination coverage. We analysed the correlation between influenza vaccination coverage and levels of socio-economic and health deprivation among the population of Cagliari, by means of an Index of Socio-Economic and Health Deprivation (SEHDI) specifically tailored to the city, in order to identify population subgroups needing specific intervention to improve vaccination coverage.

Methods. A combination of linear regression, factor analysis and cluster analysis was adopted in order to build the SEHDI at the Census Tract (CT) level; data were taken from the 2011 Italian Census. Mortality among subjects aged ≥65 years in Cagliari in the period 2013-2015 was used to select the SEHDI variables. On the basis of the SEHDI, his population was classified into five normalised deprivation groups. Information on vaccination coverage was provided by general practitioners and Local Health Units. Cause-specific mortality and information on vaccination coverage in the deprivation groups were analysed by means of ANOVA (F test at p<0.05).

Results. Around 20% of the Cagliari population was seen to be living in disadvantaged conditions. The trends in Standard Mortality Rates (SMRs) for all causes and for respiratory diseases, chronic obstructive pulmonary diseases (COPD), influenza and pneumonia were analysed across the deprivation groups. Pneumonia and flu mortality rates displayed a non-linear trend in men and a positive linear trend in women. Flu vaccination uptake rates were low: 27%. Coverage proved to be lower in the two extreme categories and higher in the medium deprivation ones.

Conclusions. The correlation between low vaccination coverage and socio-economic deprivation not only underlines the important role of vaccination in safeguarding health, but also the fact that it can be considered a factor in ensuring the system’s equality, thanks to its role in limiting health impacts on those living in the most problematic or disadvantaged circumstances. It also stresses the characteristics which contribute to low compliance. Therefore, this finding should be taken into account in the organization of vaccination campaigns and should prompt differentiated interventions in each local area.

description: The French Foreign Legion of the colonial era was mainly deployed in extra-European areas and consisted of mercenaries on five-year contracts. The situation during World War I, however, was different: A large proportion of the Legion was not deployed on colonial soil, but on the Western Front and other European theatres of war. The “classical” mercenary Legionnaires fought alongside wartime volunteers who desired to fight for France, but often were rather unhappy to have to do so in the ranks of the infamous Foreign Legion.

description: The two dimensional electron gas formed between the two band insulators SrTiO3 and LaAlO3 exhibits a variety of interesting physical properties which make it an appealing material for use in future spintronics and/or quantum computing devices. For this kind of applications electrons have to retain their phase memory for sufficiently long times or length. Using a mesoscopic size device we were able to extract the phase coherence length, and its temperature variation. We find the dephasing rate to have a power law dependence on temperature. The power depends on the temperature range studied and sheet resistance as expected from dephasing due to strong electron-electron interactions.
