Final State Interactions in Hadronic WW Decay at LEP
An overview is given of the study of final state interactions in hadronically
decaying W pairs produced in e^+e^--collisions as it is performed by the four
LEP experiments. Bose-Einstein correlations are investigated by comparing like-
with unlike-signed pairs of pions and/or using the mixed event analysis
technique. Colour reconnection is examined with a method that compares the
particle flow distributions in inter-jet regions.Comment: 6 pages, to appear in the proceedings of the XXXVIIth Rencontres de

Enactive Cognition and the Other: Enactivism and Levinas Meet Halfway
This paper makes a comparison between enactivism and Levinas’ philosophy. Enactivism is a recent development in philosophy of mind and cognitive science that generally defines cognition in terms of a subject’s natural interactions with the physical environment. In recent years, enactivists have been focusing on social and ethical relations by introducing the concept of participatory sensemaking, according to which ethical know-how spontaneously emerges out of natural relations of participation and communication, that is, through the exchange of knowledge. This paper will argue first that, although participatory sensemaking is a valuable concept in that it offers a practical and realistic way of understanding ethics, it nevertheless downplays the significance of otherness for understanding ethics. I will argue that Levinas’ work demonstrates in turn that otherness is significant for ethics in that we cannot completely anticipate others through participation or know-how. We cannot live the other’s experiences or suffering, which makes ethical relation so difficult and serious (e.g. care for a terminally ill person always falls short to a certain extent). I will argue next that enactivism and Levinas’ philosophy nevertheless do not exclude each other insofar they share a similar concept of subjectivity as a quality of naturally interacting with the external world to gain knowledge (Levinas speaks of dwelling). Finally, I will argue that enactivism’s notion of participatory sensemaking also offers something which Levinas’ insufficiently defines, namely a concept of social justice, based on equality and participation, that emerges out of natural relations

SPARX: A modeling system for Solar Energetic Particle Radiation SpaceWeather forecasting
The capability to predict the parameters of an SEP event such as its onset, peak flux, and duration is critical to assessing any potential space weather impact. We present a new flexible modeling system simulating the propagation of Solar Energetic Particles (SEPs) from locations near the Sun to any given location in the heliosphere to forecast the SEP flux profiles. Solar Particle Radiation SWx (SPARX) uses an innovative methodology that allows implementation within an operational framework to overcome the time constraints of test particle modeling of SEP profiles, allowing the production of near-real-time SEP nowcasts and forecasts, when paired with appropriate near-real-time triggers. SPARX has the capability to produce SEP forecasts within minutes of being triggered by observations of a solar eruptive event.
The model is based on the test particle approach and is spatially 3-D, thus allowing for the possibility of transport in the direction perpendicular to the magnetic field. The model naturally includes the effects of perpendicular propagation due to drifts and drift-induced deceleration. The modeling framework and the way in which parameters of relevance for Space Weather forecasting are obtained are described. The first results from the modeling system are presented. These resultsThese results demonstrate that corotation and drift of SEPtreams play an important role in shaping SEP flux profile
Proanthocyanidins from Ribes nigrum leaves - Isolation and structure determination
In summary, the antiinflammatory activity of Ribes nigrum leaves is mainly due to proanthocyanidins which are the major oligomers in the proanthocyanidins fractionPeer reviewe
Sensitivities of Future Long Baseline Experiments in the US
Sensitivities to neutrino oscillation parameters for possible very long
baseline neutrino oscillation experiments are discussed. The reach for
observing a non-zero mixing angle , establishing CP violation and
determining the mass hierarchy are compared between various experimental
options. Different possibilities for neutrino beams are briefly described, as
well as the assumptions about the performance of a large water Cherenkov and
liquid Argon detector.Comment: To appear in the proceedings of the 9th International Workshop On

CRECIMIENTO O BIENESTAR GENUINO: FORMAS ÁLTERNATIVAS DE CONTABILIDAD SOCIAL
Una economía en función de la vida requiere no solo unanueva vinculación de la economía formal con la sustantiva,sino también la supeditación de la forma al contenido. El ejede entrada para dirigir la política económica y para hacer lacontabilidad social tiende a ser el punto de vista del contenidoy ya no exclusivamente la forma. Este punto de vista implicaenfocar las políticas desde la óptica de la reproducción de lavida concreta en vez de enfocar la reproducción del dinerocomo capital. La riqueza social, enfocada a partir de lasrelaciones monetarias, se limita a la riqueza contable generadaaño tras año. Todo lo que no es contable y todo lo que no esnuevo, no figura como riqueza. De este modo, la riquezapresente se sustituye por riqueza nueva creada a costa de lamuerte de lo ya existente y así crece la economía y habríasupuestamente bienestar. Desde la óptica del contenido, lanaturaleza es riqueza y el trabajo doméstico o el voluntariadogeneran riqueza, aunque no adquieran expresión monetaria.Una parte nada despreciable de la riqueza social presente quenos rodea, no se contabiliza. Este hecho constituye el fundamentodel desprecio por la naturaleza, por el trabajo nopagado y por las cosas viejas. En tanto que la economía demercado no contabiliza esta riqueza, no cuenta, no vale naday no se pierde riqueza alguna al despilfarrada o inclusodestruirla
