Vortex stability in a multi-layer quasi-geostrophic model: application to Mediterranean Water eddies

The stability of circular vortices to normal mode perturbations is studied in a multi-layer quasi-geostrophic model. The stratification is fitted on the Gulf of Cadiz where many Mediterranean Water (MW) eddies are generated. Observations of MW eddies are used to determine the parameters of the reference experiment; sensitivity tests are conducted around this basic case. The objective of the study is two-fold: (a) determine the growth rates and nonlinear evolutions of unstable perturbations for different three-dimensional (3D) velocity structures of the vortices, (b) check if the different structure of our idealized vortices, mimicking MW cyclones and anticyclones, can induce different stability properties in a model that conserves parity symmetry, and apply these results to observed MW eddies. The linear stability analysis reveals that, among many 3D distributions of velocity, the observed eddies are close to maximal stability, with instability time scales longer than 100 days (these time scales would be less than 10 days for vertically more sheared eddies). The elliptical deformation is most unstable for realistic eddies (the antisymmetric one dominates for small eddies and the triangular one for large eddies); the antisymmetric mode is stronger for cyclones than for anticyclones. Nonlinear evolutions of eddies with radii of about 30 km, and elliptically perturbed, lead to their re-organization into 3D tripoles; smaller eddies are stable and larger eddies break into 3D dipoles. Horizontally more sheared eddies are more unstable and sustain more asymmetric instabilities. In summary, few differences were found between cyclone and anticyclone stability, except for strong horizontal velocity shears.
Neonatal hyperbilirubinaemia after induction of labour with oxytocin and cord serum albumin is compared with cord serum bilirubin as a risk indicator

Introduction: Jaundice is one of the commonest problems that can occur in a newborn. Many a times it is physiological in the newborn because liver is not mature enough to handle the bilirubin and there is an increased load of bilirubin due to a higher circulating erythrocyte volume, a shorter erythrocyte life span and a larger early labeled bilirubin peak. Objectives : 1) To know the effect of oxytocin for induction of labour in neonatal hyperbilirubenemia (NH). 2) Comparing Cord Serum Albumin level (CSA) with Cord Serum Bilirubin (CSB) in predicting neonatal hyperbilirubinemia. 3) To know the sensitivity, specificity, Positive predictive value and negative predictive value of CSA and CSB in predicting neonatal jaundice in term neonates. Method: Prospective study was performed on 789 healthy term neonates. Relevant maternal history is collected. Cord blood was collected from the healthy term neonates at birth, CSA and CSB measured. Neonate was assessed clinically every day. Total Serum Bilirubin (TSB) and blood group were assessed in neonate during 72-96 hours of life. TSB value ? 17mg/dl is considered Neonatal Hyperbilirubinemia (NH) which requires intervention like phototherapy (PT) or Exchange transfusion (ET). Result: Out of 388 Infants born after oxytocin induced labour, 122 (56.48%) neonates developed NH (P=0.002). Neonatal hyperbilirubinemia was more significant in neonates with CSA levels ? 2.8g/dl & CSB levels ? 2.1mg/dl. At cord serum albumin level ? 2.8g/dl, sensitivity, specificity, PPV and NPV are 75.93 %, 68.06 %, 47.26 and 88.24 % respectively, for predicting NH at birth. At cord serum bilirubin level ? 2.1g/dl, sensitivity, specificity, PPV and NPV are 96.30%, 70.86%, 55.47%and 98.07% respectively, for predicting NH at birth. Conclusion: Oxytocin should be used with caution in view of its ability to develop neonatal hyperbilirubinemia by inducing hemolysis. Both CSA and CSB are equally effective in predicting NH at birth. These study variables can be considered as neonatal screening tools for NH for term neonates.
A futuristic outlook on business models and business model innovation in a future green society

Companies nowadays invest more capital and resources in green technologies and increasingly start to think more radically when considering their business model innovation processes. However, the development and innovation of green business models to the so called green society is a complex venture and has not been widely researched yet. The study of green oriented innovation has intensified tremendously in the last decade due to both user demand (‘pull’) and the development of new mobile and wireless communication technologies (‘push’), which gives hope in bringing the green society vision into reality. Accordingly, this paper portrays a conceptual futuristic outlook into the development of green oriented business models, and clarifies the processes of business model innovation for the future green society.
Lipid Distribution Differentials among Smokers, Non-Smokers and within Various Types of Smokers

Data from National Health and Nutrition Examination Survey for those aged >=20 years fasting for at least 8 hours for the years 1999-2012 were used to evaluate adjusted and unadjusted differences in the levels of lowdensity- lipoprotein-cholesterol (LDL), high-densitylipoprotein- cholesterol (HDL), total cholesterol (TC), and triglyceride (TG) among self-reported current smokers and nonsmokers as well as smokers smoking cigarettes, pipes, cigars etc. Adjustments were made for the effects of gender; race/ethnicity; dietary intake of alcohol, caffeine, fatty acids, saturated and total fat; fasting time; body mass index; and frequency and intensity of smoking during the last five days. Adjusted levels of LDL, TC, and TG did not vary among smokers and nonsmokers but contrary to what could be expected, smokers were observed to have high HDL levels than nonsmokers (52.2 vs. 50.1 mg/dL, p=0.02). However, in the unadjusted analysis, smokers were found to have lower levels of HDL (48.2 vs. 52.1 mg/dL, p<0.01) and higher levels of TG (123.2 vs. 113.5 mg/dL, p<0.01) than nonsmokers but the differences for LDL (112.9 vs. 112.5 mg/dL, p=0.68) and TC (193.4 vs. 194.3 mg/dL, p=0.39) remained statistically insignificant. Adjusted levels of HDL, TC, and LDL levels did not differ among exclusive cigarette and cigar users and exclusive tobacco chewers and snuffers. Exclusive cigarette and cigar users had higher adjusted levels of TG than exclusive tobacco snuffers (125.7 and 133.8 vs. 101.5 mg/dL, p<0.01).
Prevalence of Helicobacter pylori in children 2-16 years with chronic Idiopathic thrombocytopenic purpura referred to hematology clinic of Ardabil during 2013-2015

Background: Idiopathic thrombocytopenic purpura (ITP) is the most common autoimmune blood disorder which leads to premature destruction of platelets by producing antibodies using phagocytic cells against antigens of platelets surface especially in the spleen. Recently, several studies have reported the high prevalence of H. pylori infection in adult patients with chronic ITP, but the studies performed in this area have been very limited in children. The purpose of this study is to investigate the prevalence of Helicobacter pylori infection in children with chronic ITP. Methods: In this case- control study, the case sample includes 30 children in the age range of 2-16 years with chronic ITP and control samples includes 90 children in the age range of 2-16 years who are healthy in terms of ITP disease. A questionnaire and a stool sample is prepared for each sample. These samples are examined by the method of ELIZA kit for the presence or absence of antigen H. Pylori . Data analyzed by statistical methods in SPSS.19. Results: Of the total 30 children with chronic ITP who has referred to the haematology ward of the hospital, H.pylori + 16.7%, we had H.pylori + 20% from a total of 90 controls (P=0.68). The average age of the case and control groups were 6.9±2.8 and 6.9±3 years, respectively; there is no a direct relationship between helicobacter pylori infection and sex, drinking water, but there is a statistically significant difference between platelet levels and the prevalence of H Pylori in the case group (p<0.05); however, this difference is not significant in the control group. Conclusions According to a conducted study, Helicobacter pylori infection is not considered as a factor risk in the development of chronic thrombocytopenic purpura in children. So, it is recommended that further studies to be done in different ethnic groups in the world with more samples, especially in the age range of children, so that the role of Helicobacter pylori in the pathogenesis of chronic autoimmune thrombocytopenic purpura can be determined accurately.
Effect of soil fertility management practices on nematode destroying fungi in Taita, Kenya

The effect of soil fertility management practices on nematode destroying fungi was investigated for three seasons in Taita, Kenya. The study aimed at identifying soil fertility practice that promoted nematode destroying fungi in the soil. Field experiments were established in Taita district, the treatments comprised of Mavuno fertilizer, Triple super- phosphate and calcium ammonium nitrate (TSP+CAN), cow manure and a control where no amendments were applied. This experiment was replicated in ten farms and repeated in three planting seasons. Isolation of nematode destroying fungi carried out was using the soil sprinkle technique and the isolates were identified using the key described by Cooke and Godfrey (1964). There were significant difference (P= 1.705 x 10-06) in occurrence of the nematode destroying fungi between soil fertility treatments. The highest mean (1.6) occurrence of nematode destroying fungi was recorded in soils amended with cow manure and the least (0.7) was recorded in soils from the control plots. A mean of 0.78 was recorded in soils from both TSP+CAN and Mavuno fertilizers. Plots amended with cow manure presented the highest diversity of nematodes followed by the control, then TSP+CAN and least in Mavuno with shannon indices of 0.34, 0.15, 0.13 and 0.11 respectively. Sixty percent of all the isolated nematode destroying fungi genera were from plots treated with cow manure and only twenty percent were from plots amended with the inorganic fertilizer. The control plots recorded higher number of nematode destroying fungi compared to the soils that received inorganic fertilizers.
Climate and forest fires in Finland - influence of lightning-caused ignitions and fuel moisture

The objectives of this research were to examine how lightning characteristics influence ignition probability of a lightning stroke, to study the distribution of lightning-ignited forest fires and to examine fuel moisture variation. This research utilized the comprehensive forest fire records collected by the Finnish Ministry of the Interior. Individual fires were systematically linked with individual lightning strokes to compute probabilities that a stroke has ignited a fire. A method of grouping lightning flashes into thunderstorms was developed in order to compare the ignition probability of a stroke and the characteristics of the thunderstorm to which the stroke belongs. To examine fuel moisture variation, the spatial and temporal variation in ignition probability was studied based on meteorological data, ignition experiments and Finnish forest fire risk index model. The results supported the hypothesis that a stroke in a small thunderstorm is more likely to result in ignition than a stroke in a large thunderstorm. However, the results contradicted theories predicting that positive strokes or flashes of high multiplicity would more likely result in ignition than negative strokes or flashes of low multiplicity. Positive and negative strokes were equally likely to ignite a fire and that the ignition probability of a stroke decreases with increasing multiplicity of a flash. Fuels were at their driest in late May and June in southern Finland and in late June in northern Finland. Lightning-caused ignitions were most frequent in July. Fuels were significantly dryer and lightning strokes are more frequent in southern Finland than in northern Finland. As a result, the density of lightning caused forest fires was twenty times higher in southern Finland than in northern Finland. Assuming that the natural fire cycle in southern Finland is at least 100 years, the results suggest that in northern Finland the natural fire cycle is several thousand years. If natural disturbance dynamics are mimicked in forest management and restoration, this south-north difference in natural fire regime characteristics, and consequently in forest disturbance dynamics in general, should be taken into account.
Fostering Inter-Organisational Relationships as a Way to Increase Efficiency in Tax Administration

The paper examines efficiency gains of inter-organisational cooperation within the context of federalism. The paper attempts to evaluate cooperation between federal and state agencies responsible for administration of taxes in the United States of America. The cornerstone of such cooperation is an intensive exchange of information between federal and state tax authorities. By adopting the tax structure in all relevant ways close to federal income tax structure, states may benefit from tax audit and other taxpayer return information generated by the federal government. The paper examines the federal-state cooperation in tax administration through the lens of several critical contingencies that determine the type of inter-organisational relationships. Although there is a recent tendency to make the programme a two-way street, state tax administrations receive the greater part of benefits in the consequence of cooperation.
Host‐size‐dependent feeding behaviour and progeny sex ratio of Anisopteromalus calandrae (Hym., Pteromalidae)

Host‐size related feeding and oviposition behaviour, and allocation of progeny sex by Anisopteromalus calandrae (Howard) were tested on Sitophilus oryzae L. The parasitoid showed a host‐size‐dependent partition of feeding and oviposition behaviour, preferring small hosts for feeding, but large hosts for oviposition. Neither the mutual interference nor the host density showed any effect on the behaviour of the parasitoid. Allocation of progeny sex by the female parasitoid appeared to be based more likely on absolute than on relative host size encountered. A model for the progeny sex ratio was constructed based on: (1) ovipositional preference of the parasitoid on large hosts; (2) feeding preferentially on small hosts; and (3) host‐size‐related regulation of progeny sex ratio. The progeny sex ratio of the parasitoid predicted by the model was in close agreement with the observed value.
Quantum machine learning for quantum anomaly detection

Anomaly detection is used for identifying data that deviate from `normal' data patterns. Its usage on classical data finds diverse applications in many important areas like fraud detection, medical diagnoses, data cleaning and surveillance. With the advent of quantum technologies, anomaly detection of quantum data, in the form of quantum states, may become an important component of quantum applications. Machine learning algorithms are playing pivotal roles in anomaly detection using classical data. Two widely-used algorithms are kernel principal component analysis and one-class support vector machine. We find corresponding quantum algorithms to detect anomalies in quantum states. We show that these two quantum algorithms can be performed using resources logarithmic in the dimensionality of quantum states. For pure quantum states, these resources can also be logarithmic in the number of quantum states used for training the machine learning algorithm. This makes these algorithms potentially applicable to big quantum data applications.
A Quantile Regression Analysis of Growth and Convergence in the EU: Potential Implications for Portugal

This paper applies a quantile regression approach to examine the growth and convergence process of fourteen EU member states over the period 1986-2009. From the results of the estimation of an accounting growth regression we conclude that an increase in the weight of the non-tradables sector and a loss of (price) competitiveness are especially harmful for growth for under-performing countries, while these benefit the most from physical capital accumulation and are less negatively affected by an increase in government consumption. Additionally, technological convergence is felt less strongly by low-growth member states. The variables retained are robustly related to growth at all quantiles, but the quantitative importance of the respective coefficients differs across quantiles in some cases. Given the changes in growth rhythms that Portugal recorded throughout the period under analysis, we derive some potential implications from these results for a better understanding of the Portuguese growth and convergence process after European integration. Our findings suggest that, given the growth deceleration that the Portuguese economy has been experiencing since the late 1990s, policies to enhance growth should pay more attention to promoting competitiveness and changing the specialization pattern away from the non-tradables sectors, as well as to increasing investment.
Determinants of Dairy Farmers' Market Participation in the Major Dairy Producing Towns of Jimma Zone of Southwest Ethiopia

The study was initiated with the objectives of analyzing factors affecting dairy farmers’ market participation in major milk producing towns of southwest Ethiopia. Milk and butter were the two most important dairy products marketed in the areas. Data came from 238 dairy producing households, 17 traders, and 50 consumers. Heckman two stages procedures were used to analyze factors affecting milk market participation and level of participation in the study area. The first step of the Heckman two stages procedures results showed that dairy household milk market entry decision was strongly and significantly affected by family size, number of cross breed and local breed milking cows owned, access to credit and distance from milk market center. In addition, the second stage estimation result revealed that marketable milk volume was found to be strongly and significantly affected by the number of cross breed and local breed milking cows owned, family size, and monthly non-dairy income source of sampled dairy household. 69.7% were market participants as they were found to sell raw milk at the time of the survey, while the rest (30.3%) did not sell at the time of survey. Keywords: Milk, market participation, Heckman model, southwest Ethiopia
Halo-independent comparison of direct detection experiments in the effective theory of dark matter-nucleon interactions

The theoretical interpretation of dark matter direct detection experiments is hindered by uncertainties of the microphysics governing the dark matter-nucleon interaction, and of the dark matter density and velocity distribution inside the Solar System. These uncertainties are especially relevant when confronting a detection claim to the null results from other experiments, since seemingly conflicting experimental results may be reconciled when relaxing the assumptions about the form of the interaction and/or the velocity distribution. We present in this paper a halo-independent method to calculate the maximum number of events in a direct detection experiment given a set of null search results, allowing for the first time the scattering to be mediated by an arbitrary combination of various interactions (concretely we consider up to 64). We illustrate this method to examine the compatibility of the dark matter interpretation of the three events detected by the silicon detectors in the CDMS-II experiment with the null results from XENON1T and PICO-60.

Dipolar Fermi gases in anisotropic traps

The quest for quantum degenerate Fermi gases interacting through the anisotropic and long-range dipole-dipole interaction is an exciting and fast developing branch within the cold-atom research program. Recent experimental progress in trapping, cooling, and controlling polar molecules with large electric dipole moments has, therefore, motivated much theoretical effort. In a recent letter, we have briefly discussed the application of a variational time-dependent Hartree-Fock approach to study theoretically both the static and the dynamic properties of such a system in a cylinder-symmetric harmonic trap. We focused on the hydrodynamic regime, where collisions ensure the equilibrium locally. Here we present a detailed theory extended to encompass the general case of a harmonic trap geometry without any symmetry. After deriving the equations of motion for the gas, we explore their static solutions to investigate key properties like the aspect ratios in both real and momentum space as well as the stability diagram. We find that, despite the lack of symmetry of the trap, the momentum distribution remains cylinder symmetric. The equations of motion are then used to study the low-lying hydrodynamic excitations, where, apart from the quadrupole and monopole modes, the radial quadrupole mode is also investigated. Furthermore, we study the time-of-flight dynamicsmore » as it represents an important diagnostic tool for quantum gases. We find that the real-space aspect ratios are inverted during the expansion, while that in momentum space becomes asymptotically unity. In addition, anisotropic features of the dipole-dipole interaction are discussed in detail. These results could be particularly useful for future investigations of strongly dipolar heteronuclear polar molecules deep in the quantum degenerate regime. « less
