CHA2DS2-VASc score predicts intracoronary thrombus burden in patients with ST-elevation myocardial infarction

Objective: To evaluate the role of CHA2DS2-VASc score in predicting the intracoronary thrombus burden in patients with ST-Elevation Myocardial Infarction (STEMI). Background: High intracoronary thrombus burden is associated with reduced procedural success, larger infarct size, and mortality after Primary Percutaneous Coronary Intervention (PPCI). Prediction of thrombus burden before PPCI might be useful by enabling the detection of patients at risk for these complications. Methods: We retrospectively evaluated 164 consecutive patients who presented with STEMI within 12 h after the onset of chest pain between January 2015 and June 2016. PPCI was performed within 1 h after admission. Thrombus burden was graded according to Thrombolysis in Myocardial Infarction (TIMI) thrombus score. The patients were stratified into low (grades 1, 2 and 3) and high thrombus burden groups (grades 4 and 5). CHA2DS2-VASc score was calculated for each patient. Results: Thrombus burden was low in 94 (57%) patients and high in 70 (43%) patients. CHA2DS2-VASc score was higher in patients with high thrombus burden compared to patients with low thrombus burden (4.41 ± 1.7 vs. 1.47 ± 1.1, p 2 to predict high thrombus burden was 0.925, with a sensitivity of 91% and a specificity of 82%. Conclusion: CHA2DS2-VASc score is a simple tool that predicts thrombus burden in STEMI patients undergoing PPCI.
Preliminary observations of cadmium and copper effects on juveniles of the polychaete Capitella sp. Y (Annelida: Polychaeta) from Estero del Yugo, Mazatlan, Mexico

Se investigaron los efectos de cadmio (Cd) y cobre (Cu) sobre juveniles cultivados de Capitella sp. Y. Organismos juveniles de siete dias de edad fueron expuestos a 13 (control), 60, 160, 240 y 340 mg Cd L-1 y a 17 (control), 50, 120 y 150 mg Cu L-1 durante 30 dias. La mortalidad se incremento significativamente al aumentar las concentraciones de Cu y, en las exposiciones a Cd, solamente fue evidente a 340 mg L-1. El tamano corporal y la produccion de heces fecales disminuyeron antes en los especimenes expuestos a Cu que en los expuestos a Cd, especialmente en las concentraciones mas altas de Cu. Estos resultados indican que los juveniles son mas sensibles al Cu en terminos de mortalidad, alimentacion y crecimiento. La produccion de hemoglobina fue inhibida debido a la escasez de alimento en el sedimento experimental, mas que a exposicion a los metales. La formacion de tubos no fue afectada por la presencia de metales ni por la escasez de alimento. Este estudio sugiere que concentraciones entre 50 y 150 mg L-1 de Cu y de 340 mg L-1 de Cd, podrian afectar la dinamica poblacional de esta especie en ecosistemas naturales
Knowledge and Attitude about Multidrug-Resistant Tuberculosis among Healthcare Workers in Public Health Centres

Background : Multidrug-resistant Tuberculosis (MDR-TB) is a significant public health problem and poses a threat to global tuberculosis (TB) control. In 2015, at least 504 new MDR-TB cases were identified in Indonesia. Treating MDR-TB patients is very challenging. It may take more than two years for MDR-TB treatment. Therefore, it is crucial healthcare workers (HCWs) are knowledgeable about MDR-TB. The aim of this study was to measure level of knowledge and attitude regarding MDR-TB among HCWs in public health centres. Methods : A cross-sectional study was conducted at 73 Public Health Centres in Bandung the capital of West Java Province from August until November 2015. The samples were 73 TB nurses and 32 laboratory staff. A self-administered questionnaire was given comprising 27 knowledge questions and 29 attitude questions. Correlation between knowledge and attitude scores was calculated by Pearson correlation test. Results : The majority of study participants were women (82.9%), married (92.4%), nursing staff (65.7%) with history of TB training (98.1%). Most of the participants were 40-59 years old (69.5%) with working experience in TB programme < 10 years (69.5%). Less than half (38.1%) of study participants had good knowledge. In terms of attitude, more than half (53.3%) of study participants had a positive attitude towards MDR-TB. Conclusions : The level of knowledge among HCWs about MDR-TB is still at an unacceptable level. Certain educational interventions aim to ensure prompt diagnosis, implement infection control and accurate treatment should be established among those HCWs.

Improvement on a Signed ElGamal Encryption

Previously, two schemes were proposed to enhance the security of ElGamal encryption. The weakness of the original scheme is improved by adding a message authentication tag to ciphertext. The resultant schemes are non-malleable encryption under chosen ciphertext attack. We observed that the same security goal can be achieved with less computational cost. The proposed scheme saves 33% of computing power on average. In processing decryption, it can save at most 46% of computations if the technique of multiple simultaneous exponentiations is used.
Reducing U 2 R and R 2 L Category False Negative Rates with Support Vector Machines

The KDD Cup '99 is commonly used dataset for training and testing IDS machine learning algorithms. Some of the major downsides of the dataset are the distribution and the proportions of U2R and R2L instances, which represent the most dangerous attack types, as well as the existence of R2L attack instances identical to normal traffic. This enforces minor category detection complexity and causes problems while building a machine learning model capable of detecting these attacks with sufficiently low false negative rate. This paper presents a new support vector machine based intrusion detection system that classifies unknown data instances according both to the feature values and weight factors that represent importance of features towards the classification. Increased detection rate and significantly decreased false negative rate for U2R and R2L categories, that have a very few instances in the training set, have been empirically proven.
The Dynamics of Local Employment in Western Germany

This paper studies the impact of the local industrial structure on employment dynamics in Western Germany. Following the approach of Combes/Magnac/Robin (2004) for France, local employment growth is decomposed into internal growth resulting from employment changes in existing plants and into external growth determined by employment decisions of newly established plants. The dynamics of both components are estimated simultaneously, taking explicitly into account the timing of the impact of diversity and specialisation in a region. The analysis is conducted for 21 sectors in the West German labour market regions from 1993 to 2002. Estimation results emphasize the positive influence of diversity and competition in a region, whereas no clear evidence on the role of specialization emerges. Furthermore, static externalities dominate. Importantly, the impact of the local industrial structure on employment does not dier between small and larger plants, nor are there major dierences between Western Germany and France.
An inverse relation between Pb2+ and Ca2+ ions accumulation in Phaseolus mungo and Lens culinaris under Pb stress.

This study focuses attention on accumulation of Pb in root and shoot of Phaseolus mungo and Lens culinaris in relation with Ca from nutrient solution in which PbCl2 was added. The plants were cultivated in natural environment. It was observed that Pb physically blocks water uptake which results in decline length of root and shoot with reduced leaf size of both species. This may be attributed with reduced fresh weight, and ratio of dry and fresh weight of two species. The accumulation trend of Pb and Ca showed a linear relation in between applied dose and accumulation of Pb in Phaseolus mungo and Lens culinaris which inversely related with Ca contents of both members of Fabaceae family. The reduced Ca contents was due to chemical similarities in between the oxidation states of two ions but smaller ionic radius and high density of Pb helps in accumulation of it in tissues of both species. These interactions may occur at the cellular and molecular level and are the abilities of Pb to displace Ca during specific physiological process. It is likely that Pb blocks Ca efflux from cells by substituting Ca in Ca / Na during some enzymatic activity.
Slobodan Lakic: CONCENTRATION IN BANKING – A PARADIGM OF MANIPULATIVE CONTROL AND POWER 53 CONCENTRATION IN BANKING – A PARADIGM OF MANIPULATIVE CONTROL AND POWER

The paper starts from the hypothesis that concentration of banking industry and ownership is a ground for proliferation of financial control and power, enabling financial clique to abuse the banking and credit system. Banking super-entities ensure manipulative pattern of functioning based on the monopolistic standard of demand of money, mechanism of interest rates and derivative market. Current financial crisis has deepend the concentrated system of relations and redestribution. The practice based on fraud and deception remained a cornerstone of strengthening the Anglo-Saxon banking and industrial empire to the current shaken model of financialization. Official monetary authorities, under the control of “sophisticated” individuals and semi-secret organizations, provide safe traditional and unconventional monetary and liquidity mechanism to corporate bankers.

Effects of Different Photoperiods • and Different Nutrients on the Longevity of Endoparasitoid Venturia canescens ( Grav . ) ( Hymenoptera : Ichneumonidae ) Reared from Two Different Host Stages

Effects of different photoperiods (16:8 h light: dark, and continuous darkness), and different diet treatments (water, honey and no food) on the longevity of Venturia canescens (Grav.) developed from different larval stages of Ephestia kuehniella Zeller (L3 and L5) were determined at 25±1°C and 60-70 % relative humidity under laboratory conditions. There were no significant differences between nutrient and photoperiod treatments, and among nutrient, photoperiod and host stage treatments for the longevity of the parasitoid. However, there were significant difference between host stage and nutrient treatments, and host stage and photoperiod treatments for the longevity of the parasitoid. In different host stages and different diet treatments, maximum longevity, 23,21 days, was observed in parasitoids which developed from L5 and fed with honey. In different host stages and different photoperiod treatments, maximum longevity was obtained when parasitoid were developed from L5 in each photoperiod treatments. These results when evaluated in respect of mass culture of V. canescens showed that longevity of the parasitoid significantly increased when mature larvae of E. kuehniella were used as host and feeding with honey.
Option Implied Trees and Implied Moments

Implied trees are simple non-parametric discretizations of one- or two-dimension diffusions, aimed at introducing non-constant volatility in an option pricing model. The aim of the paper is twofold. First we investigate the ability of different option implied trees in pricing European options. Second, we compare the implied moments obtained with the use of option implied trees with the risk–neutral moments obtained with the use of Bakshi et al. (2003) formula and with realised physical moments. The comparison is pursued in the Italian market by analysing a data set which covers the years 2005-2009 and span both a relatively tranquil and a turmoil period.
Decoherence of Polaron in Asymmetric Quantum Dot Qubit Under an Electromagnetic Field

In this paper, we investigate the time evolution of the quantum mechanical state of a polaron using the Pekar type variational method on the electric-LO-phonon and the magnetic-LO-phonon strong coupling in a quantum dot. We obtain the Eigen energies and the Eigen functions of the ground state and the first excited state, respectively. In a quantum dot, this system can be viewed as a two level quantum system qubit. The superposition state polaron density oscillates in the quantum dot with a period τ_0when the polaron is in the superposition of the ground and the first-excited states. The spontaneous emission of phonons causes the decoherence of the qubit. We show that the density matrix of the qubit decays with the time while the coherence term of the density matrix element 〖 p〗_01 (〖 or p〗_10) decays with the time as well for different coupling strengths, conﬁnement lengths, and dispersion coefficients. The Shannon entropy is evaluated in order to investigate the decoherence of the system.
Complementing quantitative typology with behavioral approaches: Evidence for typological universals

Two main classes of theory have been advanced to explain correlations between linguistic features like those observed by Greenberg (1963). arbitrary constraint theories argue that certain sets of features patterm together because they have a single underlying cause in the innate language faculty (e.g., the Principles and Parameters program; see Chomsky & Lasnik 1993). functional theories argue that languages are less likely to have certain combinations of properties because, although possible in principle, they are harder to learn or to process, or less suitable for efficient communication (Hockett 1960, Bates & MacWhinney 1989, Hawkins 2004, Dryer 2007, Christiansen & Chater 2008; for further discussion see Hawkins 2007 and Jaeger & Tily 2011). The failure of Dunn, Greenhill, Levinson & Gray (2011) to find systematic feature correlations using their novel computational phylogenetic methods calls into question both of these classes of theory. Dunn et al.’s methodology is a principled and powerful new way of evaluating change-based theories of language typology, but it faces fundamental challenges common throughout quantitative typology. Typological data is usually sparse, and additional data hard or impossible to obtain. The statistical power to detect an effect (e.g., to detect universal tendencies) is reduced by uncertainty about the genealogical relations between languages, the period of time during which a language was spoken, and the amount of contact with other languages. It is hence possible that the failure to find support for word order universals reported in Dunn et al. 2011 is a spurious null effect (see Croft et al. 2011, in this issue, who also discuss other potential methodological issues with that study). To some extent, this is a critique that can be leveled at much work on quantitative typology: sparse and uncertain data weakens the conclusions that can be drawn from it.

Fermi-LAT high-z active galactic nuclei and the extragalactic background light

Observations of distant gamma-ray sources are hindered by the presence of the extragalactic background light (EBL). In order to understand the physical processes that result in the observed spectrum of sources, it is imperative that a good understanding of the EBL is included. In this work, an investigation into the imprint of the EBL on the observed spectra of high-redshift Fermi-LAT active galactic nuclei is presented. By fitting the spectrum below ∼10 GeV, an estimation of the unabsorbed intrinsic source spectrum is obtained; by applying this spectrum to data up to 300 GeV, it is then possible to derive a scaling factor for different EBL models. A second approach uses five sources (PKS 0426−380, 4C +55.17, Ton 116, PG 1246+586 and RBS 1432) that were found to exhibit very high energy (VHE) emission (Eγ > 100 GeV). Through Monte Carlo simulations, it is shown that the observation of VHE photons, despite the large distances of these objects, is consistent with current EBL models. Many of these sources would be observable with the upcoming ground-based observatory, the Cherenkov Telescope Array, leading to a better understanding of the EBL.
Association of Pregnant Sudanese Women Plasma Essential Fatty Acids Levels and Their Neonates Head Circumference

Essential fatty acids are polyunsaturated fatty acids (PUFA) which contain more than one double bond. The purpose of this study was to investigate the level of fatty acid composition in plasma of neonates and compare them to their head circumference. There were no records about the levels of these fatty acids in Sudanese people. Blood samples were obtained from the maternal side of the cord during delivery in Khartoum state hospitals. Full and detailed history and examinations were performed in the study groups. Plasma lipids were extracted by Folch method and separated by Gas Liquid Chromatography (GLC). These results were expressed as mean and standard deviations. The differences in mean were compared by Mann-Whitney U test using SPSS for windows version 15. The mean head circumference of our neonates was (29±0.6 cm) range (28-35 cm) which was lower than the standard value (35±1.7 cm). Our study demonstrated a negative correlation between head circumference of neonates with different saturated fatty acids and linoleic acid (r=-0.36,-0.34) (p≤0.05), and positively with other omega -6 and omega-3 fatty acids of neonates (r=0.53) (p≤0.05). Low level of neonatal DHA and high level of LA interfere with our neonatal head circumference, which was lower than the international level.

The Impact of Official Aid on Poverty Reduction: Empirical Evidence from Nigeria (1981-2014) Using The ARDL and Bound Test Approach

Aid flows to developing countries is ultimately intended to help recipient countries attain sustainable development especially in the area of capital development, sustained economic growth, poverty reduction and reduced mortality rate. The justifications for increasing official aid to the poor countries of the world have constantly come under scrutiny and have generated intense debate among researchers. Against this background, this study is aimed at assessing the impact of official aid on poverty reduction in Nigeria from 1981 to 2014. The ARDL and the error correction model (ECM) were used to estimate for long-run and short-run dynamics respectively, while the Bound test was employed to test for long-run relationship between our variables of interest. Result of the Bound test showed that there exist a long-run relationship between official aid flows and poverty. Both long-run and short-run regression estimates revealed that official aid has non-significant positive impact on poverty reduction within the period. There is however strong sign of convergence toward long-run equilibrium as the speed of adjustment is significantly high. The results further showed that population growth exerted negative influence on poverty reduction both in the long and short-run whereas labour force participation was found to have relative positive impact on poverty reduction. We therefore conclude that while it is evident that official aid has positive influence on poverty reduction, the influence so established is not significant. We recommend that aid donors and international aid organizations should earmark aids for a specific needs and exhaust every prudential steps in making sure that such aid are used for the targeted aim with fact-based appraisals and implementation reports.

Viscoelastic effects of blood flow in nondeformable capillary

A polydisperse structure of blood, the major portion of which is made up of erythrocytes accounts for its complicated rheological behavior. To a first approximation, the blood flow in a vessel is simulated by a stationary motion of viscoelastic fluid in a capillary with nondeformable walls. An exact analytical solution has been developed for a Poiseuille flow of viscoelastic fluid whose behavior is described by the generalized 6constant Jeffreys model. The velocity profile is obtained in a parametric form where the velocity gradient at the capillary wall is used as a parameter. It has been demonstrated that at pressure gradients exceeding the obtained critical values the longitudinal velocity profiles show slight tangential discontinuities. The predicted phenomenon of hysteresis is shown to be associated with a monotonic decrease/increase in the pressure gradient over a certain range of parameters.
The polarities of psychological well being and their response to treatment

An increasing number of investigations in the positive psychology area has suggested the benefits of improving well-being and positivity. However, observations from clinical domains raised some concerns on the effectiveness and utility of such interventions, because excessively elevated levels in positive domains could become detrimental and impede flourishing. The aim of this article is to describe these polarities in well-being and to suggest specific therapeutic strategies to promote flourishing and resilience. Well-being therapy (WBT) is a psychotherapeutic technique based on Ryff’s conceptual model, that has been developed and tested in a number of randomized controlled trials. The differential technical characteristics and indications of WBT are described, with special reference to the promotion of an individualized and balanced path to achieve optimal human functioning, avoiding the polarities in positive psychological dimensions.
Effect of Viscoelasticity on Nanoindentation Measurements: An Application to Bone Tissues

Nanoindentation is a powerful technique to determine the mechanical properties of materials at small volumes. This article reviews the current understanding of nanoindentation testing, in particular under viscoelastic effect. The effect of strain rate and the condition or process of the sample preparation on measurements of hardness and elastic modulus has been discussed. A special focus on its applications to bone tissue is also addressed.
MEMS Devices for Miniaturized Gas Chromatography

In the era of the Internet of Things, the need for mobile devices able to analyze accurately real samples with sometimes very small volumes is a must. Gas chromatography (GC) is a common laboratory technique widely used for analyzing semi-volatile and volatile compounds. However, this technique is not suitable to be used outside labs. The development of micro-machined processes encouraged the development of miniaturized gas chromatographs. This chapter focuses on the recent development in the field of miniaturized gas chromatography and its component up to the present in various fields of analyses.
