Three-dimensional multispecies hybrid simulation of Titan's highly variable plasma environment

Abstract. The interaction between Titan's ionosphere and the Saturnian magnetospheric plasma flow has been studied by means of a three-dimensional (3-D) hybrid simulation code. In the hybrid model, the electrons form a mass-less, charge-neutralizing fluid, whereas a completely kinetic approach is retained to describe ion dynamics. The model includes up to three ionospheric and two magnetospheric ion species. The interaction gives rise to a pronounced magnetic draping pattern and an ionospheric tail that is highly asymmetric with respect to the direction of the convective electric field. Due to the dependence of the ion gyroradii on the ion mass, ions of different masses become spatially dispersed in the tail region. Therefore, Titan's ionospheric tail may be considered a mass-spectrometer, allowing to distinguish between ion species of different masses. The kinetic nature of this effect is emphasized by comparing the simulation with the results obtained from a simple analytical test-particle model of the pick-up process. Besides, the results clearly illustrate the necessity of taking into account the multi-species nature of the magnetospheric plasma flow in the vicinity of Titan. On the one hand, heavy magnetospheric particles, such as atomic Nitrogen or Oxygen, experience only a slight modification of their flow pattern. On the other hand, light ionospheric ions, e.g. atomic Hydrogen, are clearly deflected around the obstacle, yielding a widening of the magnetic draping pattern perpendicular to the flow direction. The simulation results clearly indicate that the nature of this interaction process, especially the formation of sharply pronounced plasma boundaries in the vicinity of Titan, is extremely sensitive to both the temperature of the magnetospheric ions and the orientation of Titan's dayside ionosphere with respect to the corotating magnetospheric plasma flow.
The relationship between emotional intelligence and transformational leadership: an investigation and review of competing claims in the literature

Following a review of the literature on the relationship between emotional intelligence (EI) and transformational leadership (TL), this paper provides an analysis of the findings of 22 published papers, examining the range of instruments used to collect data, sample sizes, dates of publication and the reported conclusions. This review reveals that investigations into the relationship between EI and TL continue to yield mixed results, and have done so for almost 15 years now, indicating that this field of research continues to be a contested area. Recommendations for advancing the scientific investigation of the EI-TL relationship are put forward.
Nursing care missed in patients at risk of or having pressure ulcers

ABSTRACT Objective: to determine the nursing care missed as perceived by the nursing staff and its relation with the nursing care missed identified in the assessment of patients at risk of or having pressur ulcers. Method: descriptive correlation study. The participants were 161 nurses and 483 patients from a public hospital. The MISSCARE survey was used in combination with a Nursing Care Assessment Form for Patients at Risk of or having pressure ulcers. For the analysis, descriptive and inferential statistics were used. Results: the nursing staff indicated greater omission in skin care (38.5%), position change (31.1%) and the registration of risk factors for the development of pressure ulcers (33.5%). The nursing care missed identified in the assessment related to the use of pressure relief on bony prominences and drainage tubes interfering in the patient's movements (both with 58.6%) and the use of pneumatic mattresses (57.6%). Conclusion: a high percentage of nursing care missed was found according to the staff's perception. Nevertheless, the assessment of the nursing care missed was much higher. No significant relation was found between both. Therefore, it is a priority to reflect on the importance of objective patient assessments.
Computational studies on electron and proton transfer in phenol‐imidazole‐base triads

The electron and proton transfer in phenol‐imidazole‐base systems (base = NH2− or OH−) were investigated by density‐functional theory calculations. In particular, the role of bridge imidazole on the electron and proton transfer was discussed in comparison with the phenol‐base systems (base = imidazole, H2O, NH3, OH−, and NH2−). In the gas phase phenol‐imidazole‐base system, the hydrogen bonding between the phenol and the imidazole is classified as short strong hydrogen bonding, whereas that between the imidazole and the base is a conventional hydrogen bonding. The n value in spn hybridization of the oxygen and carbon atoms of the phenolic CO sigma bond was found to be closely related to the CO bond length. From the potential energy surfaces without and with zero point energy correction, it can be concluded that the separated electron and proton transfer mechanism is suitable for the gas‐phase phenol‐imidazole‐base triads, in which the low‐barrier hydrogen bond is found and the delocalized phenolic proton can move freely in the single‐well potential. For the gas‐phase oxidized systems and all of the triads in water solvent, the homogeneous proton‐coupled electron transfer mechanism prevails. © 2009 Wiley Periodicals, Inc. J Comput Chem, 2010
3.2 Choline and Its Products Acetylcholine and Phosphatidylcholine Choline

Choline, a quaternary amine obtained largely from the diet but also synthesized in the brain and, especially, liver, is an essential precursor of the neurotransmitter acetylcholine (ACh) and of the major membrane constituent phosphatidylcholine (PC). Plasma choline concentrations can vary over a fivefold range depending on the choline contents of the foods being digested. Since choline readily crosses the blood–brain barrier (BBB) through an unsaturated facilitated‐diffusion system, these plasma changes can produce parallel changes in brain choline levels. In addition, since the enzymes that convert choline to ACh [choline acetyltransferase (ChAT)] and PC’s precursor phosphocholine [choline kinase (CK)] are also poorly saturated with their choline substrate, increases in plasma choline can enhance the formation of ACh and phosphocholine, and the release of ACh. The subsequent conversion of phosphocholine to PC is increased if PC’s other circulating precursors (uridine and omega‐3 fatty acids) are provided. This leads to an increase in the levels of synaptic membrane within the brain. Choline is principally metabolized in the liver to betaine, which provides a source of methyl groups for the regeneration of methionine and S‐adenosylmethionine.
Correlations between Community Structure and Link Formation in Complex Networks

Background Links in complex networks commonly represent specific ties between pairs of nodes, such as protein-protein interactions in biological networks or friendships in social networks. However, understanding the mechanism of link formation in complex networks is a long standing challenge for network analysis and data mining. Methodology/Principal Findings Links in complex networks have a tendency to cluster locally and form so-called communities. This widely existed phenomenon reflects some underlying mechanism of link formation. To study the correlations between community structure and link formation, we present a general computational framework including a theory for network partitioning and link probability estimation. Our approach enables us to accurately identify missing links in partially observed networks in an efficient way. The links having high connection likelihoods in the communities reveal that links are formed preferentially to create cliques and accordingly promote the clustering level of the communities. The experimental results verify that such a mechanism can be well captured by our approach. Conclusions/Significance Our findings provide a new insight into understanding how links are created in the communities. The computational framework opens a wide range of possibilities to develop new approaches and applications, such as community detection and missing link prediction.
Intrapulmonary Cystic Lymphangioma in a 2-month-old Infant

Lymphangioma is an abnormal collection of lymphatics that are developmentally isolated from the normal lymphatic system. Lymphangioma rarely presents as a solitary pulmonary lesion. We report a rare case of intrapulmonary cystic lymphangioma involving the upper lobe of the right lung, which presented with dyspnea in a 2-month-old infant. High-resolution computed tomography (HRCT) of the chest demonstrated a well-circumscribed, multiseptate, cystic lesion in the upper lobe of the right lung, mimicking the feature of type I congenital cystic adenomatoid malformation. The tumor was removed by bilobectomy of the upper and middle lobes of the right lung, and its pathologic examination confirmed the diagnosis of an intrapulmonary cystic lymphangioma.
SparseNet: Coordinate Descent With Nonconvex Penalties

We address the problem of sparse selection in linear models. A number of nonconvex penalties have been proposed in the literature for this purpose, along with a variety of convex-relaxation algorithms for finding good solutions. In this article we pursue a coordinate-descent approach for optimization, and study its convergence properties. We characterize the properties of penalties suitable for this approach, study their corresponding threshold functions, and describe a df-standardizing reparametrization that assists our pathwise algorithm. The MC+ penalty is ideally suited to this task, and we use it to demonstrate the performance of our algorithm. Certain technical derivations and experiments related to this article are included in the Supplementary Materials section.
Development of a Web Site Usability Instrument Based on ISO 9241-11

The importance of Web site usability is apparent. Previous studies have found that a usable Web site creates a positive attitude toward online stores, increases stickiness and revisit rates, and eventually stimulates online purchases. A usable Web site also provides benefits to e-business by reducing website development, support, and maintenance costs. The ISO 9241-11 standard for usability has been one of the standards for defining usability in several areas, particularly that of Web sites. This study builds on Quesenbery's reformulation of the ISO 9241-11 standards for Web site usability by developing an instrument to measure its dimensions. The results of the study found an appropriate instrument for Web site usability that showed some nomological validity, although raising questions about its comprehensiveness as a measure of all important dimensions of usability.
Radio Mode Outbursts in Giant Elliptical Galaxies

Outbursts from active galactic nuclei (AGN) affect the hot atmospheres of isolated giant elliptical galaxies (gE’s), as well as those in groups and clusters of galaxies. Chandra observations of a sample of nearby gE’s show that the average power of AGN outbursts is sufficient to stop their hot atmospheres from cooling and forming stars, consistent with radio mode feedback models. The outbursts are intermittent, with duty cycles that increases with size.
β-tubulin paralogue tubC is frequently misidentified as the benA gene in Aspergillus section Nigri taxonomy: primer specificity testing and taxonomic consequences

β-tubulin (benA, tub-2) and calmodulin (caM) are crucial genes in the taxonomy of Aspergillus section Nigri. Widely used β-tubulin primers are not specific for the benA gene for some taxa and preferentially amplify the tubC paralogue. Sequences of the tubC paralogue are widely combined with benA sequences in recent taxonomical works as well as other works, resulting in incongruent trees. In this study we newly provide benA sequences for several ex-type strains, which were characterised using the tubC gene only. We designed a highly specific forward primer to benA designated Ben2f for use in Aspergillus section Nigri, and tested specificity of numerous primer combinations to β-tubulin paralogs. The primer pairs with the highest specificity to the benA gene and functional across species in section Nigri includes Ben2f/Bt2b, Ben2f/T22 and T10/T22. We also provide tools based on codon usage bias analysis that reliably distinguish both paralogues. Exon/intron arrangement is the next distinctive characteristic, although this tool is not valid outside section Nigri. The species identity of taxa from the A. aculeatus clade used in previous molecular studies was revised using combined molecular data (ITS, benA, caM). These data together with two different PCR-fingerprinting methods indicated that A. japonicus should be treated as a synonym of A. violaceofuscus. Similarly, A. fijiensis is reduced to synonymy with A. brunneoviolaceus.
RELATIONSHIP BETWEEN TRADE OPENNESS AND ECONOMIC GROWTH OF INDIA: A TIME SERIES ANALYSIS

The empirical relationship between trade openness and economic growth of India has been a debatable issue. The existing literature fails to provide an unambiguous answer. The paper examines this empirical relationship for the time period 1970-2010 using Vector Autoregression method and demonstrates that the relationship has evolved over time following the regime change in the early 1980s when the Indian economy started to move from a state-led growth model to a pro-market regime. Therefore, any assumption of a static trade-growth nexus may lead to inaccurate findings. Our econometric results indicate that growth in trade volumes accelerates economic growth of India since 1980-81 onwards. We do not find evidence of any significant association between trade barriers and growth.
On analytic continuation of various multiple zeta-functions Kohji Matsumoto

In this article we describe the development of the problem of analytic continuation of multiple zeta-functions. We begin with the work of E. W. Barnes and H. Mellin, and then discuss the Euler sum and its multivariable generalization. Recently, M. Katsurada discovered that the classical Mellin-Barnes integral formula is useful to the study of analytic continuation of the Euler sum. We will explain Katsurada’s idea in Section 4. Then in the last two sections we will present new results of the author, which are obtained by using the Mellin-Barnes formula to more general multiple zeta-functions. 1 Barnes multiple zeta-functions The problem of analytic continuation of multiple zeta-functions was first considered by Barnes [7][8] and Mellin [48][49]. Barnes [7] introduced the double zeta-function of the form ζ2(s;α, (w1, w2)) = ∞ ∑
Reflections on Manner/Result Complementarity*

Nonstative verbs from various lexical fields are often classified as either manner or result verbs—a distinction implicated in language acquisition (Behrend 1990, Gentner 1978, Gropen et al. 1991), as well as in argument realization. Intuitively speaking, manner verbs specify as part of their meaning a manner of carrying out an action, while result verbs specify the coming about of a result state. Verbs of each type are listed in (1). As the lists illustrate, the manner/result distinction crosscuts the transitive/intransitive distinction.
Isolation and differentiation of Rivulus hartii across Trinidad and neighboring islands

Diversification of freshwater fishes on islands is considered unlikely because the traits that enable successful colonization—specifically, broad salinity tolerances and the potential for oceanic dispersal—may also constrain post‐colonization genetic differentiation. Some secondary freshwater fish, however, exhibit pronounced genetic differentiation and geographic structure on islands, whereas others do not. It is unclear what conditions give rise to contrasting patterns of differentiation because few comparative reconstructions of population history have been carried out for insular freshwater fishes. In this study, we examined the phylogeography of Hart’s killifish (Rivulus hartii) across Trinidad, with reference to neighboring islands and northern South America, to test hypotheses of colonization and differentiation derived from comparable work on co‐occurring guppies (Poecilia reticulata). Geographic patterns of mitochondrial DNA haplotype variation and microsatellite genotype variation provide evidence of genetic differentiation of R. hartii among islands and across Trinidad. Our findings are largely consistent with patterns of geographically structured ancestry and admixture found in Trinidadian guppies, which suggests that both species share a history of colonization and differentiation and that post‐colonization diversification may be more common among members of insular freshwater fish assemblages than has been previously thought.
Gene polymorphisms of the macrophage migration inhibitory factor and acute pancreatitis.

CONTEXT Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine that is released by macrophages and lymphocytes and plays an important pathogenetic role in acute pancreatitis. It is present in large amounts in the serum and ascitic fluid in rats with experimental pancreatitis and its levels are elevated in humans with pancreatitis. Polymorphisms associated with inflammatory joint diseases exist in the promoter region of the macrophage migration inhibitory factor gene that alter its expression. OBJECTIVE We investigated the association of macrophage migration inhibitory factor polymorphisms with acute pancreatitis in a population in the UK. PARTICIPANTS A cohort of 164 patients with acute pancreatitis and 197 healthy controls. MAIN OUTCOME MEASURES The -173 G to C single nucleotide polymorphism and the -794 (CATT) n repeat microsatellite were investigated. Restriction fragment length polymorphism (RFLP) was used to assay the -173 polymorphism and PCR followed by polyacrylamide gel electrophoresis (PAGE) was used for the microsatellite. RESULTS The microsatellite did not show any significant differences in distribution between patients and controls. The -173 GG genotype showed a trend towards reduced frequency seen in patients (P=0.056) and the C allele was significantly over expressed in patients (P=0.025). No differences were observed in subgroups based on severity or aetiology of pancreatitis. CONCLUSIONS The -173 C allele is over expressed in acute pancreatitis, however studies are needed to explore this further. Our distribution of the microsatellite alleles was quite different to a previously reported Caucasian population and needs further study from viewpoint of population genetics.
POST KEYNESIAN MONETARY THEORY AND ITS IMPLICATIONS FOR MONETARY POLICY IN SOUTH AFRICA

The theoretical foundations of the Post Keynesian view of money are examined, including the nature of money, role of uncertainty and time, and the use of equilibrium concepts. This provides a backdrop against which the Post Keynesian analysis of interest rates, investment behaviour: inflation and demand determination is presented in a framework of non-neutral money and Keynes' principle of effective demand. A model of the Post Keynesian theory of money is presented, with arguments as to why the IS/LM model of the neoclassical synthesis is considered deficient. The money supply endogeneity view is explored, together with Keynes' finance motive. The open economy case is considered, with emphasis on a small open economy. The monetary policy perspectives of the Post Keynesian camp are examined. The implications for South Africa are considered in respect of money supply targeting, interest rate policy, anti-inflation measures, public debt management, exchange rates and Reserve Bank objectives. Key terms: Monetary analysis; nonergodic; endogenous; finance motive; marginal efficiency of capital; monetary equilibrium; principle of effective demand; Post Keynesian; interest rate; exchange rate; monetary policy; Reserve Bank; South Africa.
Prognostic score systems and community-acquired bacteraemic pneumococcal pneumonia

The aim of this study was to evaluate the accuracy of three score systems: the pneumonia severity index (PSI); CURB-65 (confusion; urea >7 mM; respiratory rate ≥30 breaths·min-1; blood pressure <90 mmHg systolic or ≤60 mmHg diastolic; aged ≥65 yrs old); and modified American Thoracic Society rule for predicting intensive care unit (ICU) need and mortality due to bacteraemic pneumococcal pneumonia. All adult patients (n = 114) with invasive pneumococcal pneumonia at the Karolinska University Hospital, Sweden, 1999–2000, were included in the study. Severity scores were calculated and the independent prognostic importance of different variables was analysed by multiple regression analyses. PSI ≥IV, CURB-65 ≥2, and the presence of one major or more than one minor risk factor in mATS all had a high sensitivity, but somewhat lower specificity for predicting death and ICU need. The death rate was 12% (13 out of 114). Severity score and treatment in departments other than the Dept of Infectious Diseases were the only factors independently correlated to death. Patients treated in other departments more often had severe underlying illnesses and were more severely ill on admission. However, a significant difference in death rates remained after adjustment for severity between the two groups. In conclusion, all score systems were useful for predicting the need for intensive care unit treatment and death due to bacteremic pneumococcal pneumonia. The pneumonia severity index was the most sensitive, but CURB-65 was easier to use.
Temperament and coping: Advantages of an individual differences perspective

This paper examines the advantages that arise from an individual differences approach to children's coping and vulnerabilities. It suggests that the basic motivational and attentional systems involved in temperament constitute relatively primitive coping mechanisms. With development, these primitive coping skills are aided by representational and other cortical functions, allowing the coping process to begin before a stressful event and thereby increasing the child's capacity to plan an effective coping option and to enhance self-control. Such an emphasis on motivational and attentional differences allows us to take advantage of children's diverse personalities as “experiments of nature” and to better understand the temperamental patterns that contribute to adaptive and maladaptive outcomes.
