Proton entry into the near-lunar plasma wake for magnetic field aligned flow

We report the first observation of protons in the near-lunar (100-200 km from the surface) and deeper (near anti-subsolar point) plasma wake when the interplanetary magnetic field (IMF) and solar wind velocity (vsw) are parallel (aligned flow; angle between IMF and vsw≤10°). More than 98% of the observations during aligned flow condition showed the presence of protons in the wake. These observations are obtained by the Solar Wind Monitor sensor of the Sub-keV Atom Reflecting Analyser experiment on Chandrayaan-1. The observation cannot be explained by the conventional fluid models for aligned flow. Back tracing of the observed protons suggests that their source is the solar wind. The larger gyroradii of the wake protons compared to that of solar wind suggest that they were part of the tail of the solar wind velocity distribution function. Such protons could enter the wake due to their large gyroradii even when the flow is aligned to IMF. However, the wake boundary electric field may also play a role in the entry of the protons into the wake.

The 2002 European registry of cardiac catheter interventions

OBJECTIVE: The tradition of yearly reports on cardiac catheter interventions in Europe has been initiated in 1992. This 11th report presents aggregated data on cardiac catheter procedures in 30 European countries in the year 2002. DESIGN AND SETTING: A detailed questionnaire addressing summary data of all cardiac interventions was mailed to presidents or delegates of the national societies of cardiology in Europe. The questionnaire was distributed to all institutions with cardiac catheterisation programs. All questionnaires were compiled in a national summary data sheet, then entered into a central database and subsequently analysed. MAIN OUTCOME MEASURES: Coronary angiography, PTCA, and stenting in absolute numbers and per million inhabitants in the participating countries and the whole of Europe. RESULTS: Overall, 1,901,932 coronary angiograms were reported. The population-adjusted rate of coronary angiograms amounted to an absolute mean of 3358 per 10(6) inhabitants, an increase of 7% compared with 2001. A total of 686,869 PTCA procedures were reported. The mean European number of PTCAs per 10(6) inhabitants increased by 10% from 1103 in 2001 to 1213 in 2002. Procedures with stenting increased by 17% from 508,999 to 593,906. The stenting rate was 86% compared with 82% in 2001. CONCLUSIONS: In pace with epidemiological demand and the need to catch-up from underuse in certain countries, a continuous and considerable growth of coronary interventions can be observed. It will take years to find out whether the announced change of paradigm in the treatment of multivessel disease in the wake of drug-eluting stents will come true.

Regional differences in trait-like characteristics of the waking EEG in early adolescence

BACKGROUND The human waking EEG spectrum shows high heritability and stability and, despite maturational cortical changes, high test-retest reliability in children and teens. These phenomena have also been shown to be region specific. We examined the stability of the morphology of the wake EEG spectrum in children aged 11 to 13 years recorded over weekly intervals and assessed whether the waking EEG spectrum in children may also be trait-like. Three minutes of eyes open and three minutes of eyes closed waking EEG was recorded in 22 healthy children once a week for three consecutive weeks. Eyes open and closed EEG power density spectra were calculated for two central (C3LM and C4LM) and two occipital (O1LM and O2LM) derivations. A hierarchical cluster analysis was performed to determine whether the morphology of the waking EEG spectrum between 1 and 20 Hz is trait-like. We also examined the stability of the alpha peak using an ANOVA. RESULTS The morphology of the EEG spectrum recorded from central derivations was highly stable and unique to an individual (correctly classified in 85% of participants), while the EEG recorded from occipital derivations, while stable, was much less unique across individuals (correctly classified in 42% of participants). Furthermore, our analysis revealed an increase in alpha peak height concurrent with a decline in the frequency of the alpha peak across weeks for occipital derivations. No changes in either measure were observed in the central derivations. CONCLUSIONS Our results indicate that across weekly recordings, power spectra at central derivations exhibit more "trait-like" characteristics than occipital derivations. These results may be relevant for future studies searching for links between phenotypes, such as psychiatric diagnoses, and the underlying genes (i.e., endophenotypes) by suggesting that such studies should make use of more anterior rather than posterior EEG derivations.

Myoepithelioma of the cerebellopontine angle: a previously not documented benign salivary gland-type neoplasm within the cranium

Myoepithelioma is a dimorphic neoplasm with contractile-epithelial phenotype, originally interpreted as deriving from, but not actually restricted to the salivary glands. As a novel addition to the list of exquisitely rare intracranial salivary gland-type tumors and tumor-like lesions, we report on an example of myoepithelioma encountered in the left cerebellopontine angle of a 32-year-old male. Clinically presenting with ataxia and dizziness, this extraaxial mass of 4 × 3.5 × 3 cm was surgically resected, and the patient is alive 6 years postoperatively. Histologically, the tumor exhibited a continuum ranging from compact fascicles of spindle cells to epithelial nests and trabeculae partitioned by hyalinized septa, while lacking tubular differentiation. Regardless of architectural variations, there was robust immunoexpression of S100 protein, smooth muscle actin, GFAP, cytokeratin, and vimentin. Cytologic atypia tended to be modest throughout, and the MIB1 labeling index averaged less than 1%. Fluorescent in situ hybridization indicated no rearrangement of the EWSR1 locus. We interpret these results to suggest that myoepithelioma of the posterior fossa - along with related salivary epithelial tumors in this ostensibly incongruous locale - may possibly represent analogous neoplasms to their orthotopic counterparts, ones arising within aberrant salivary anlagen. The presence of the latter lends itself to being mechanistically accounted for by either postulating placodal remnants in the wake of branchial arch development, or linking them to exocrine glandular nests within endodermal cysts. Alternatively, myoepithelioma at this site could be regarded as a non tissue-specific lesion similar to its relatives ubiquitously occurring in the soft parts.

Electoral and Financial Bookkeeping: A Comparison of Pre-Electoral Pledges on Public Spending and the Outcome of Post-Electoral Budget Debates

In the wake of the financial crisis, budgetary discipline has taken centre stage in politics. More than ever a country's budget mirrors the true policy preferences of the legislative majority beyond all political discourse and cheap talk. The paper sheds light on mandate fulfilment in the field of public spending and fiscal policy in general. Based on previous work on pledge fulfilment in Switzerland the paper compares publicised pre-electoral statements of MPs on public spending and the development of the public finances with their post-electoral legislative behaviour during budget debates and votes. The findings of the paper confirm the results of the aforementioned earlier studies and point to the potential of budgetary statements for future mandate fulfilment research.

Actigraphic monitoring of physical activity in clinical trials in schizophrenia

Schizophrenia is still associated with poor outcome, which is mainly related to negative symptoms, reduced physical activity and low quality of life. Physical activity can be objectively measured without distress using wrist actigraphy. The activity levels during the wake periods of the day have been informative on psychopathology and antipsychotic medication. Several studies demonstrated prominent negative symptoms to be associated with reduced activity levels with strongest correlations in chronic patients. Particularly, the avolition score is correlated with reduced activity levels. Moreover, activity levels differ between DSM-IV schizophrenia spectrum disorders and subtypes as well as between patients treated with olanzapine or risperidone. The longitudinal course of activity levels during an psychotic episode demonstrates considerable variance between subjects. During a psychotic episode patients with low activity levels at baseline experience an amelioration of negative symptoms. In contrast, patients with high activity levels at baseline have stable low negative syndrome scores. Between psychotic episodes less variance is observed. Actigraphy is easily applied in schizophrenia and allows collecting large amounts of crosssectional or longitudinal data. With larger numbers of subjects in controlled trials, continuous recording of activity would foster the detection of different outcome trajectories, which may prove as useful groups to target interventions. In clinical trials, activity monitoring may supplement and validate measures of the negative syndrome and its avolition factor or serve as an outcome marker for physical activity, which is important for metabolic issues and quality of life.

Polonofilizm i polskość wśród czeskich emancypantek w drugiej połowie XIX wieku: przykład Karoliny Světlej

The awakening of national consciousness went hand in hand in Bohemia with an anxiety about national disappearance. In this context, the recourse to Pan-Slavism was for the Czechs a way to encourage themselves through the idea of belonging to a great Slavic world, while the Slavic Congress organized in Prague in 1848 was an attempt to realize this ideal. The Congress was a failure from the political point of view, but it did have some socio-cultural repercussions: notably, it served as a pretext for the advancement of women's issues in Bohemia. It is indeed in the wake of the Congress that Honorata z Wiśniowskich Zapová, a Polish women settled in Prague after her marriage to a Czech intellectual, founded, under the guise of collaboration between all Slavic women, the first women's association, as well as a (very short-lived) Czech-Polish institute, where Czech, as well as Polish girls, could get a quality education in their mother tongue. Honorata was undoubtedly the source of the polonophilia wind that seemed to blow over the Czech emancipation movement in the second half of the nineteenth century. In particular, Karolina Světlá showed in her Memoirs a great recognition for Honorata's efforts in matters of emancipation and education, and explicitly took up the challenge launched by the latter in founding another women's association and in inaugurating a school for underprivileged girls. But the tribute Světlá paid to Honorata is even more evident in her literary work, where Poland and the Polish woman (who often wears Honorata's features) play a significant role (see for example her short novel Sisters or her story A Few Days in the Life of a Prague Dandy). Světlá was probably the Czech feminist writer who, in her activities and in her work, relied most strongly on the Polish woman as a model for the Czech woman. However, she wasn't alone. In general, it was a characteristic of the Czech feminist movement of the second half of the nineteenth century to have recourse to the Polish woman and to Poland as a landmark for comparison and as a goal to be achieved.

Disciplining Investment Incentives: A Lost Cause?

An E15 Initiative think piece: Investment incentives rank among the most important policy instruments governments employ to influence the locational decisions of multinational firms. In the wake of the recent increase in locational competition and the growing impact of investment incentives and support measures for state-owned enterprises (SOEs), the need for enhanced disciplines on investment incentives has gained political and academic salience. This think piece explores the evolution of investment incentives from a development and rule-making perspective. It summarises the existing literature and examines current practices and recent trends in FDI flows and the use of various investment incentives. This is followed by a discussion of the reasons for the observed stalemate in attempts at disciplinary rule-making. The paper concludes by putting forth recommendations for data gathering and transparency that could further the move toward improved global governance founded on the increasing complementarities of trade, investment, and competition law and policy as the core pillars of a more open, inclusive, and just world economy.
