Benefits of lipid regulation in acute coronary syndrome

Lipid lowering therapy with statins has proven beneficial in patients with acute coronary syndrome (ACS). Outcome trials have demonstrated that the high risk of a recurrent coronary event or stroke can be reduced by about 15% using these agents. Further, greater benefit appears to be present when more aggressive treatment regimens (higher statin doses) are followed. Lipoprotein levels measured in the days following an ACS episode may not be a good guide to therapy due the effects of the acute phase response. Other lipid regulating modalities including HDL raising drugs are being explored. Theoretically, these approaches could be beneficial not only in facilitating reverse cholesterol transport but also in altering inflammatory and oxidative pathways. Their utility needs to be tested rigorously in clinical trials.
A local existence result for a system of viscoelasticity with physical viscosity

We prove the local in time existence of regular solutions to the system of equations of isothermal viscoelasticity with clamped boundary conditions. We deal with a general form of viscous stress tensor $\mathcal{Z}(F,\dot F)$, assuming a Korn-type condition on its derivative $D_{\dot F}\mathcal{Z}(F, \dot F)$. This condition is compatible with the balance of angular momentum, frame invariance and the Claussius-Duhem inequality. We give examples of linear and nonlinear (in $\dot F$) tensors $\mathcal{Z}$ satisfying these required conditions.
What Do You Think Of My Ink ? What Do You Think of My Ink ? Assessing the Effects of Body Art on Employment Chances Human Resource Management

[rh] What Do You Think Of My Ink? What Do You Think of My Ink? Assessing the Effects of Body Art on Employment Chances Human Resource Management Andrew R Timming, Dennis Nickson, Daniel Re, and David Perrett Abstract Using mixed design analysis of variance, this paper examines the effect of body art on job applicant hireability ratings. It employs the literatures on the social psychologies of stigma and prejudice, as well as aesthetic labor, to frame the argument. The results indicate that photos of tattooed and pierced job applicants result in lower hireability ratings compared to the control faces. The negative effect of body art on employment chances is, however, reduced for job applicants seeking non-customerfacing roles. In customer-facing roles, the tattoo is associated with lower hireability ratings than the piercing. The results suggest that visible body art can potentially be a real impediment to employment.
Middle leadership: Critical variables in building and implementing digital reforms in primary mathematics education

The aim of this paper is propositional and is based on research findings which suggest that success in mathematics teaching and reform is contingent upon having key personnel in schools to lead curriculum reform. Based on the outcomes of a large national study on successful practice in the teaching of numeracy for some of Australia’s most disadvantaged learners, it was found that, among other practices, the appointment of a numeracy leader alongside the use of effective and appropriate digital tools (in particular apps) supported teachers to implement strong and effective numeracy practices. This paper presents a rationale for a renewed focus on practices that will enable success for all Australian students, but most particularly those who are most at risk of mathematical mortality.
Benchmarking the MEKAL spectral code with solar X-ray spectra

With the likelihood that high-resolution soft X-ray spectra of non-solar astronomical sources will soon become available, it is desirable to examine the accuracy of spectral synthesis codes. In this paper, a benchmark study of the MEKAL code, extensively used in the past for spectra from , , SAX , and other spacecraft, is presented using high-resolution solar flare X-ray spectra obtained with the Bragg Flat Crystal Spectrometer (FCS) on SMM . Lines in the range 5-20 A are used to adjust the wavelengths in the MEKAL code. Many of the lines are due to Fe ions, and arise from 3-2 transitions for spectra obtained during the decay phase of one of the flares, while others arise from higher-excitation (4-2, 5-2 etc.) transitions for spectra obtained near the peak of a second flare. Laboratory measurements of the wavelengths of these lines were also used to confirm the SMM values as well as published identifications from the HULLAC atomic code. The adjustments needed were up to 35 mA for line wavelengths above 13 A but much less at shorter wavelengths. Some of these adjustments will be perceptible for spectra from the forthcoming XMM and Chandra spacecraft.
Occupational Choice and the Process of Development

This paper models economic development as a process of institutional transformation by focusing on the interplay between agents' occupational decisions and the distribution of wealth. Because of capital market imperfections, poor agents choose working for a wage over self-employment, and wealthy agents become entrepreneurs who monitor workers. Only with sufficient inequality, however, will there be employment contracts; otherwise, there is either subsistence or self-employment. Thus, in static equilibrium, the occupational structure depends on distribution. Since the latter is itself endogenous, we demonstrate the robustness of this result by extending the model dynamically and studying examples in which initial wealth distributions have long-run effects. In one case the economy develops either widespread cottage industry (self-employment) or factory production (employment contracts), depending on the initial distribution; in the other example, it develops into prosperity or stagnation.
Using a discrete choice experiment to estimate societal health state utility values

In this study we explore a novel application of the Discrete Choice Experiment (DCE) that resembles the Time Trade Off (TTO) task to estimate values on the health utility scale for the EQ-5D. The DCE is tested in a survey alongside the TTO in respondents largely representative of the Canadian general population. The study finds that the DCE is able to derive logical and consistent values for health states valued on the full health – dead scale. The DCE overcame some issues identified in the version of TTO currently used to value EQ-5D, notably whether to exclude respondents who fail to understand the task and incorporating values considered worse than dead without transformation. This has important implications for providing values that represent the preferences of all respondents.
Graph-Based Global Reasoning Networks

Globally modeling and reasoning over relations between regions can be beneficial for many computer vision tasks on both images and videos. Convolutional Neural Networks (CNNs) excel at modeling local relations by convolution operations, but they are typically inefficient at capturing global relations between distant regions and require stacking multiple convolution layers. In this work, we propose a new approach for reasoning globally in which a set of features are globally aggregated over the coordinate space and then projected to an interaction space where relational reasoning can be efficiently computed. After reasoning, relation-aware features are distributed back to the original coordinate space for down-stream tasks. We further present a highly efficient instantiation of the proposed approach and introduce the Global Reasoning unit (GloRe unit) that implements the coordinate-interaction space mapping by weighted global pooling and weighted broadcasting, and the relation reasoning via graph convolution on a small graph in interaction space. The proposed GloRe unit is lightweight, end-to-end trainable and can be easily plugged into existing CNNs for a wide range of tasks. Extensive experiments show our GloRe unit can consistently boost the performance of state-of-the-art backbone architectures, including ResNet, ResNeXt, SE-Net and DPN, for both 2D and 3D CNNs, on image classification, semantic segmentation and video action recognition task.
Induction Chemotherapy Followed by Concomitant Chemoradiation in Head and Neck Squamous Cell Carcinoma: A Single Institution Experience

Objective: Phase 3 studies are underway to compare induction chemotherapy (IC) followed by concomitant chemoradiation (CRT) with CRT alone in advanced head and neck cancer. The purpose is to report the outcome of patients with advanced head and neck cancer treated at Centre Hospitalier de l’Universite de Montreal (CHUM) with IC followed by CRT. Methods: From March 1998 to December 2007, 56 consecutive patients were treated for advanced squamous cell carcinoma of the head and neck with high-dose IC followed by CRT. Sixteen patients with carcinoma of the nasopharynx, paranasal sinuses or nasal cavity were excluded. Patients presented with either T4 (60%) or N3 (60%) disease. Outcomes were computed using Kaplan-Meier curves. The number of IC cycles were compared with logrank tests. Results: The 2 year estimates of OS, DFS, LRC and DMFS rates were 58%, 46%, 78% and 75% respectively. At last follow-up, we observed 17 patients with relapse of which 10 were at a distant site. When stratified by the number of IC cycles, a DMFS rate of 87% was observed for 1-2 cycles vs 49% for 3 cycles, p=0.05. Conclusions: Despite intensive treatment with platinum based IC and CRT, prognosis for this highly advanced population of T4 or N3 cancers is poor. The number of IC cycles seem to influence the rate of DM. Further trials are needed to answer the question regarding IC followed by CRT vs CRT alone. Targeted therapies might also yield more promising results.
Effect of protein source on digestion and growth performance of early-weaned rabbits

Four diets based on different vegetal protein concentrates: soya bean meal 48 (SB48 diet), soya bean protein concentrate (SB61 diet), sunflower meal 36 (SF36 diet) and a combination of soya bean meal 48 and potato protein concentrate (SB48-P77 diet) were formulated for the starter pe- riod (25-39 days) in early weaned rabbits (25 days of age). These sources of protein accounted for 30% of the total dietary crude protein (CP) content. All diets were formulated to be isonutritive and to meet or exceed all the essential nutrient requirements of growing rabbits. A feeding trial was con- ducted to measure the effect of the treatments on growth performance in 204 rabbits that were fed ad libitum the experimental diets in the starter period and thereafter received a common feed until 60 d of age. Faecal and ileal apparent digestibility of dry matter (DM) and CP (9 and 7 replicates, respec- tively) were determined at 35 d of age. The weights and pH of the stomach and caecal contents, am- monia concentration in the caecum and jejunal morphology were also determined (11 rabbits per diet). The treatments did not affect faecal DM and CP digestibility. However, the source of protein af- fected ileal digestibilities of DM and CP (P < 0.04), which were around 14 and 7% higher for SB61 and SF36 diets, respectively, than for the SB48 diet, whereas the values obtained for the SB48-P77 diet were intermediate. The ileal flux of CP and the N-NH3 caecal concentration were (P = 0.08 and 0.05, respectively) affected by the source of protein. The highest values were observed in animals fed the SB48-P77 diet, increasing by around 25 and 35%, respectively, compared to the other three diets. The treatments had no effect on digestive traits and jejunal morphology. The differences in ileal di- gestion efficacy among treatments led to differences (P = 0.008) in food efficiency the first week after weaning, which was higher (10%, as average) in animals fed the SB61 diet than that observed for ani- mals fed the SB48 and SB48-P77 diets, whereas the value obtained for SF36 was intermediate. In this period, the type of diet tended (P = 0.08) to affect daily gain and food efficiency, with the lowest val- ues obtained for the SB48 diet. The treatments had no effect on mortality in the first two weeks after weaning. However, mortality in the whole fattening period was affected by protein source (P = 0.03), since it was higher in animals fed the SB48-P77 diet after weaning than the animals fed the other three diets (34.6 vs. 16.7%, respectively). In conclusion, SF36 and SB61 are the sources of protein that led 461
On the X-ray temperature of hot gas in diffuse nebulae

X-ray emitting diffuse nebulae around hot stars are observed to have soft-band temperatures in the narrow range [1-3]$\times10^{6}$ K, independent of the stellar wind parameters and the evolutionary stage of the central star. We discuss the origin of this X-ray temperature for planetary nebulae (PNe), Wolf-Rayet nebulae (WR) and interstellar wind bubbles around hot young stars in our Galaxy and the Magellanic Clouds. We calculate the differential emission measure (DEM) distributions as a function of temperature from previously published simulations and combine these with the X-ray emission coefficient for the 0.3-2.0 keV band to estimate the X-ray temperatures. We find that all simulated nebulae have DEM distributions with steep negative slopes, which is due to turbulent mixing at the interface between the hot shocked stellar wind and the warm photoionised gas. Sharply peaked emission coefficients act as temperature filters and emphasize the contribution of gas with temperatures close to the peak position, which coincides with the observed X-ray temperatures for the chemical abundance sets we consider. Higher metallicity nebulae have lower temperature and higher luminosity X-ray emission. We show that the second temperature component found from spectral fitting to X-ray observations of WR nebulae is due to a significant contribution from the hot shocked stellar wind, while the lower temperature principal component is dominated by nebular gas. We suggest that turbulent mixing layers are the origin of the soft X-ray emission in the majority of diffuse nebulae.
SHORT COMMUNICATION High frequency of cagA and vacA s1a/m2 Genotype among Helicobacter pylori Infected Gastric Biopsies of Pakistani Children

The vacuolating cytotoxin VacA and cytotoxin associated gene product CagA, encoded by vacA and cagA are major virulence determinants associated with pathogenesis of Helicobacter pylori. The presence and prevalence of two major H. pylori virulence associated genes among gastric biopsies of Pakistani children were investigated in the current study. Fifty one gastric biopsy specimens of children were analysed for 16S rRNA, vacA and cagA genes using PCR. The results showed that 21 (41.2%) biopsies were positive for H. pylori as determined by 16S rRNA PCR. In the 21 H. pylori positive gastric biopsies, 19 (90.5%) showed vacA s1a, 1 (4.75%) was vacA s1b and 1 (4.75%) was vacA s2 whereas, 5 (23.8%) were vacA m1 and 16 (76.2%) were vacA m2. None of the H. pylori positive biopsies carried vacA s1c subtype. The cagA gene was found in 13 (61.9%) of H. pylori infected biopsies and different vacA combinations were found with or without cagA gene. H. pylori was detected with high frequency of cagA while vacA s1a and vacA m2 regions with vacA s1a/m2 genotype were predominant in H. pylori infected gastric biopsies of children.
Improving opinion poll reporting: the Irish Polling Indicator

ABSTRACT This article describes a statistical method for aggregating the information from Irish opinion polls. Such aggregate estimates provide academic researchers with a time series of support for political parties, and inform the public better about opinion polls by focusing on trends and uncertainty in these estimates. The article discusses the challenge of aggregating opinion polls in a multi-party setting with a comparatively limited number of polls available and presents daily estimates of party support for the 1987–2016 period. The article develops a method to better model major sudden political and societal events, which have been common in Ireland since 2007. Finally, it discusses how polling aggregation estimates can enhance opinion poll reporting in the media.
Experimental study on drag reduction in a duct

We investigate drag forces on liquids pumped through a duct coated with a magnetic liquid of kinematic viscosity of 1.69 cSt. Due to a suitable arrangement of a set of permanent magnets, the magnetic liquid formed a fluid layer on the bottom of a square duct through which a silicone oil with a kinematic viscosity of 50 cst was pumped. Applied magnetic flux densities ranged from less than 0.01 T to about 0.15 T at the surface of the magnets. The influences of the strength and gradient of the magnetic field, and of the fluid flow rate, on the shape of the magnetic fluid have been investigated. It is not practical to form a uniform magnetic fluid layer under our experimental conditions, and consequently the drag was increased compared with the uncoated case because the flow of the silicone fluid over the magnetic fluid layer deformed this layer dramatically. For a viscosity ratio between the main flow and the ferrofluid less than about 30, it is therefore not feasible to use a magnetic fluid layer to reduce the drag in a duct. However, the generally high thermal conductivity of magnetic liquids, its convection, and interface deformation, might be exploited for heat transfer enhancement
Price Dynamics under the presence of Threshold Effects in WTI Crude Oil Markets

We analyzed long-run adjustment process to equilibrium and short-run dynamics with WTI spot and futures prices using bivariate 3-regime TVECM. After dividing the entire sample period into 5 sub-samples, we applied this model to each sub-sample. This allows us to figure out the differentiable effects of market conditions which can vary by sub-samples and regimes, on investors' behaviors. The estimation results showed quite interesting points. First, the middle regimes of all 5 sub-samples were not targeted by investors, so we could find their activities only in lower and/or upper regimes. Second, we can make 3 different groups with 5 sub-samples. Period 1 showed brisk movements in futures markets under the price information leadership of spot markets and relatively longer adjustment time compared to the other 4 periods. Period 2, 3, and 4 showed the opposite phenomena to period 1 probably caused by sporadic big shocks on world economy. Period 5 showed mixed results in lower and upper regimes. We could analyze quite differentiable and opposite adjustments according to regimes in this period even under the dominated contango condition, which could be regarded as the precious harvest of employing a bivariate 3-regime TVECM in this paper.
Toward improvement of the properties of parts manufactured by FFF ( Fused Filament Fabrication) through understanding the influence of temperature and rheological behaviour on the coalescence phenomenon

In this paper, the printing temperature ranges of PLA and PEEK, two semi-crystalline thermoplastics, have been investigated for the Fused Filament Fabrication (FFF) process. The printing range, comprised between the melting temperature and the degradation of each polymer, is 160°C to 190°C for PLA and 350°C to 390°C for PEEK. The complex viscosity has been measured for both polymers within the printing range. The kinetics of coalescence has been registered by measuring the bonding length between two filaments of the same polymer according to the temperature. At 167°C, the filaments of PLA reached the maximum value of bonding length. For PEEK, the filaments reached the maximum value of bonding length at 380°C. For the both materials, the final height of the filament is 80% of the initial diameter. The comparison of the obtained results with experimental study and predictive model shows a good agreement when the polymer is totally in fusion state.
Ionospheric assimilation techniques for ARGOS Low‐Resolution Airglow and Aurora Spectrograph (LORAAS) tomographically reconstructed equatorial electron density profiles

The LORAAS instrument aboard the ARGOS satellite observes line‐of‐sight ultraviolet limb intensities from ionosphere and thermosphere airglow. This study uses tomographically reconstructed electron density profiles (EDPs) from the nightside emissions. The ionospheric reconstruction is performed using a two‐dimensional O+ 1356Å radiative recombination forward model and discrete inverse theory. The forward model assumes a Chapman layer for the vertical electron density distribution from which hmF2, NmF2, and topside scale height are derived for every 90 s limb scan, which is equivalent to 5° resolution in latitude. Since ARGOS is in a near Sun‐synchronous orbit, these EDPs form a latitude slice through the equatorial anomaly structures at approximately 0230 LT. These data reflect ongoing ionospheric processes, and it is necessary to assimilate or compare with a model that contains appropriate ionospheric evolution such as the ionospheric forecast model (IFM). This study addresses the reasonableness of both the reconstructed EDPs and the IFM in describing the equatorial anomalies' diurnal and weather variability. The comparison of the LORASS EDPs with those of IFM for October 2000 show that the EDP reconstruction results compare favorably to the IFM EDPs in peak height and topside scale height. Additionally, the sector‐to‐sector climatology of the observed and modeled equatorial anomalies is similar to within the resolution of the instrument and model. The variability observed in each pass of the satellite is much larger than the IFM variability. The LORASS observation variability indicates that careful assessment of the representation error of the observations should be addressed through supplemental observations.
Exploring the Aspirations of Kolkatan (Calcuttan) Street Children Living On and Off the Streets Using Drawings

The aims of the present study were to represent the aspirations of Kolkatan street children and to draw comparisons across gender and between children "on the streets" and "off the streets". The participants were 151 Street Children from Kolkata (Calcutta), India, 66 males (43.7%) and 85 females (56.3%), of which 51 (33.8%) were "on the streets" and 100 (66.2%) were "off the streets". They were asked to draw a picture of the sort of person they wanted to be when they grew up and to write who the person was, what they were doing, and why they were chosen. Content analysis identified themes evident in the drawings and comments. Frequency analysis and chi-square tests were used to identify patterns in these themes. Kappa coefficients for inter-rater reliability on a random sample of 10% of drawings reached the minimum 0.7 level for all themes. The most common occupations recorded were Teacher (n= 48, 31.8%), and Doctor, (n= 29, 19.2%) and there was a majority of higher socio-economic status (SES) occupations with high Educational requirements. Boys were more likely to draw male stereotypes and girls non-gender specific roles. Girls were more likely than boys to depict Helping as a Contribution and boys more likely than girls to depict Defence. These results are discussed with reference to patterns of themes identified and to the role of gender in some of the differences. Finally, some of the difficulties with the present study are posed as potential questions for further research.
A Token-based Protocol for Securing MQTT Communications

Security in the Internet of Things is a current and important research topic as it may encompass different aspects such as confidentiality and integrity of personal data, as well as the authentication and the authorization to access smart devices and sensors that are spreading day-by-day in our lives. In this paper we focus onto MQTT (Message Queue Telemetry Transport), a message-based communication protocol explicitly designed for low-power sensors and based upon the publish-subscribe paradigm. First of all, we describe some of the security solutions and improvements typically suggested in the literature for deployments of MQTT. Then, we present a possible alternative solution to protect specific topics in MQTT based on AugPAKE protocol. The proposed solution has been implemented through ActiveMQ middleware and successfully tested.
