Collision probabilities in the rarefaction fan of asymmetric exclusion processes

We consider the one-dimensional asymmetric simple exclusion process (ASEP) in which particles jump to the right at rate p is an element of (1/2, 1.] and to the left at rate 1 - p, interacting by exclusion. In the initial state there is a finite region such that to the left of this region all sites are occupied and to the right of it all sites are empty. Under this initial state, the hydrodynamical limit of the process converges to the rarefaction fan of the associated Burgers equation. In particular suppose that the initial state has first-class particles to the left of the origin, second-class particles at sites 0 and I, and holes to the right of site I. We show that the probability that the two second-class particles eventually collide is (1 + p)/(3p), where a collision occurs when one of the particles attempts to jump over the other. This also corresponds to the probability that two ASEP processes. started from appropriate initial states and coupled using the so-called ""basic coupling,"" eventually reach the same state. We give various other results about the behaviour of second-class particles in the ASEP. In the totally asymmetric case (p = 1) we explain a further representation in terms of a multi-type particle system, and also use the collision result to derive the probability of coexistence of both clusters in a two-type version of the corner growth model.

Considerations about the recommendations of the Commission on the Limits of the Continental Shelf on the Amazon fan

In 2004, Brazil submitted to the Commission on the Limits of the Continental Shelf (CLCS) a Submission for the outer limit of the Brazilian continental shelf for its extension beyond the limits of 200 nautical miles. In 2007, the CLCS presented its recommendations, however it did not recommend four areas proposed by Brazil, the Amazon Fan among them. The objective of this study is to present the main legal and technical aspects of the controversy about the Amazon Fan, in order to evaluate some alternatives for a future submission, new or revised.

TWO NEW RECORDS OF Isomyia paurogonita FANG AND FAN, 1986 AND Sumatria latifrons Malloch, 1926 (DIPTERA: CALLIPHORIDAE) FROM NORTHERN THAILAND, WITH REVISED KEY TO THE SPECIES OF Isomyia

During the annual fly survey at Doi Nang Kaew in Doi Saket District, Chiang Mai Province of Thailand in 2011, Isomyia paurogonitaFang & Fan, 1986 (Diptera: Calliphoridae) and Sumatria latifrons Malloch, 1926 (Diptera: Calliphoridae) were collected for the first time in Thailand. They are the rare species of the subfamily Rhiniinae (tribe Cosminini). Prior to this finding, fifteen species of Isomyia and two species of Sumatriawere recorded from Thailand. Therefore, 96 blow fly species have been found in this country. These new locality records of both flies are very important for further research on their biology and ecology in Thailand.

Enhancing fan experience during live sports broadcasts through second screen applications

When sports fans attend live sports events, they usually engage in social experiences with friends, family members and other fans at the venue sharing the same affiliation. However, fans watching the same event through a live television broadcast end up not feeling so emotionally connected with the athletes and other fans as they would if they were watching it live, together with thousands of other fans. With this in mind, we seek to create mobile applications that deliver engaging social experiences involving remote fans watching live broadcasted sports events. Taking into account the growing use of mobile devices when watching TV broadcasts, these mobile applications explore the second screen concept, which allows users to interact with content that complements the TV broadcast. Within this context, we present a set of second screen application prototypes developed to test our concepts, the corresponding user studies and results, as well as suggestions on how to apply the prototypes’ concepts not only in different sports, but also during TV shows and electronic sports. Finally, we also present the challenges we faced and the guidelines we followed during the development and evaluation phases, which may give a considerable contribution to the development of future second screen applications for live broadcasted events.

Untersuchungen zur Eignung der Leitfähigkeitsmessung für die FAN-Bestimmung in Bierwürze

Der Maischprozess beeinflusst die Qualität des Bieres maßgeblich und ist Ausgangspunkt für die Effizienz nachfolgender Produktionsschritte. Daher ist es erstrebenswert, Qualitätsschwankungen während des Maischens zu erkennen und direkt Einfluss zu nehmen. Die prozessbegleitende Überwachung des Maischens wurde lange außer Acht gelassen und beschränkte sich auf die Erfassung nur einer Konzentration (z.B. Stammwürzegehalt) bzw. einzelner physikalischer Größen. Ziel dieser Arbeit ist es, die Korrelation zwischen dem Gehalt an α-Aminostickstoff und der Leitfähigkeit während der Maischeführung - beruhend auf einem standardisierten Verfahren - nachzuweisen bzw. zu bestätigen.

Anàlisi del coneixement, de l'actitud i de l'ús que fan els cuidadors informals dels malalts d' Alzheimer en el domicili, de les contencions mecàniques i farmacològiques

L’objectiu d’aquest estudi consisteix en saber quins coneixements posseeixen, quines actituds i quin ús fan els cuidadors informals de persones diagnosticades d’Alzheimer en el domicili, de les contencions mecàniques i farmacològiques. Aquest projecte es tracta d’un disseny exploratori, descriptiu i transversal. Per a realitzar-lo es prendrà com a mostra a cuidadors principals informals, que tinguin al seu càrrec persones diagnosticades d’Alzheimer que siguin usuàries de l’atenció primària dels serveis sanitaris públics, de la província de Barcelona. L’estudi integrarà dues fases: la primera consistirà en realitzar una prova pilot a un nombre reduït de persones que servirà per avaluar i perfeccionar l’eina de la recollida de dades (els instruments a emprar seran una enquesta d’elaboració pròpia i entrevistes) i la segona consistirà en efectuar la recollida de dades a partir de l’enquesta modificada i validada en la fase anterior. En la fase pilot es realitzarà l’anàlisi de les dades a través de la tècnica coneguda com <> i en la fase següent, s’utilitzarà el paquet estadístic SPSS versió 21.0.0.
