CFRAMP's large pelagic fish tagging program
CFRAMP\u27s Large Pelagic Fish Tagging Program was established to examine the distribution and movement patterns of Thunnus atlanticus (blackfin tuna), Acanthocybium solandri (wahoo), Coryphaena hippurus (dolphinfish), and Scomberomorus cavalla (king mackerel), large pelagic fish species of commercial importance to several Caribbean countries. The Program explored several means to facilitate fish tag and release activities, involving collaborative partnerships with national fisheries administrations, the recreational fishing sector, and individual commercial fishers. A Iotal of 1,143 fish were tagged and released in the coastal waters of several islands within the Eastern Caribbean: 787 blackfin tuna, 250 wahoo, 89 dolphinfish, and 17 king mackerel. To date, only 13 recaptures have been reported. Eleven (11) blackfin tuna, released in the coastal waters of St Vincent and the Grenadines were recaptured near to, or at original release sites after times at liberty ranging from 5 d to 1,230 d. Similarly, 2 king mackerel, released off the west coast of Trinidad, were recaptured very near original release sites after 74 and 129 d at liberty
Electroweak Fits and Constraints on the Higgs Mass
The current status of the quantities entering into the global electroweak
fits is reviewed, highlighting changes since Summer 2003. These data include
the precision electroweak properties of the Z and W bosons, the top-quark mass
and the value of the electromagnetic coupling constant, at the scale of the Z
boson mass. Using these Z and W (high Q^2) data, the value of the Higss mass is
extracted, within the context of the Standard Model (SM). The consistency of
the data, and the overall agreement with the SM, are discussed.Comment: 8 pages, 5 postscript figure

A Bayesian Filtering Algorithm for Gaussian Mixture Models
A Bayesian filtering algorithm is developed for a class of state-space
systems that can be modelled via Gaussian mixtures. In general, the exact
solution to this filtering problem involves an exponential growth in the number
of mixture terms and this is handled here by utilising a Gaussian mixture
reduction step after both the time and measurement updates. In addition, a
square-root implementation of the unified algorithm is presented and this
algorithm is profiled on several simulated systems. This includes the state
estimation for two non-linear systems that are strictly outside the class
considered in this paper
Mediterranean horse cultures: Greek, Roman and Arabic equine texts in late medieval and early modern Andalusia.
En les histoĢries de la peniĢnsula ibeĢrica de lāedat mitjana i moderna les difereĢncies entre la cavalleria islaĢmica i cristiana sāhan convertit en una manera dāilĀ·lustrar diferents formes dāorganitzacioĢ social i significats culturals vinculats amb la relacioĢ entre cavall i genet. EĢs a dir, les praĢctiques de la cavalleria ācom a conjunt dāestils, teĢcniques i funcionsā tambeĢ impliquen connotacions regionals, religioses i eĢtniques, i en efecte han acabat transformant el significat (la tradicioĢ equĢestre) en el significant (un element de distincioĢ de territoris i identitats). Tanmateix, la frontera religiosa de la praĢctica de la cavalleria musulmana ibeĢrica es mostra molt subtilment analitzada a la llum de la circulacioĢ recurrent dāequins, experts equĢestres i textos relacionats amb equins en un context circummediterrani. Replantejar les cultures del cavall ibeĢriques dins del marc de connectivitats mediterraĢnies meĢs extenses posa en evideĢncia un corpus comuĢ de coneixements sobre el cavall, sovint constret de manera excessiva per denominacions regionals, imperials o etnicoreligioses i destaca els aspectes multifuncionals de cavalls, genets i textos sobre aquests animals. En centrarse en les praĢctiques particulars que constitueixen les tradicions de la cavalleria, en lloc que en les identitats culturals que impliquen les seves etiquetes, el coneixement de les cultures mediterraĢnies del cavall pot ajudar els historiadors a entendre meĢs a fons la diplomaĢcia i lāestrateĢgia militar en el context de les fronteres cristianomusulmanes.In histories of medieval and early modern Iberia, distinctions between āChristianā and āMuslimā cavalries have become shorthand for differing forms of social organization and cultural meaning embedded in the relationship between horse and rider. In other words, practices with horsesāas amalgamations of style, technique, and functionāalso imply region, religion, and eth- nicity, in effect, transforming the signified (the equestrian tradition) into the signifier (a marker of boundaries and identities). However, the religious boundaries implied by the use of Iberian Muslim horse culture are rapidly undermined by examination of the recurrent circulation of equines, equestrian experts, and equine-related texts in a circum-Mediterranean context. Reframing Iberian horse cultures within broader Mediterranean connectivities illuminates a common body of equine knowledge uneasily contained by regional, imperial, or ethnic-religious denominations, and emphasizes the dynamic multi-functionality of horses, riders, and texts about horses. By focusing on the particular practices constituting cavalry traditions, rather than the cultural identities their labels imply, the notion of Mediterranean horse cultures can better aid historians in deciphering outcomes of diplomacy and military strategy across Christian-Muslim borders.En las historias de la peniĢnsula ibeĢrica medieval y moderna, las distinciones entre la caballeriĢa islaĢmica y cristiana se han convertido en una cifra de diferentes formas de organizacioĢn social y de significados culturales vinculados con la relacioĢn entre caballo y jinete. En otras palabras, las praĢcticas de la caballeriĢa ācomo conjunto de estilos, teĢcnicas y funcionesā tambieĢn implican connotaciones regionales, religiosas y eĢtnicas, y en efecto han acabado trans- formando el significado (la tradicioĢn ecuestre) en el significante (un elemento distintivo de territorios e identidades). Sin embargo, la frontera religiosa de la praĢctica de la caballeriĢa islaĢmica ibeĢrica aparece muy sutil si se considera la circulacioĢn recurrente de equinos, expertos ecuestres y textos relacionados con equinos en un contexto circunmediterraĢneo. Replantear las culturas de los caballos ibeĢricos dentro de conectividades mediterraĢneas maĢs amplias permite apreciar un corpus de conocimientos comunes sobre el caballo, a menudo constrenĢido de manera excesiva por denominaciones regionales, imperiales o eĢtnico-religiosas, y enfatiza los aspectos multifuncionales de caballos, jinetes y textos sobre caballos. Al centrarse en las praĢcticas particulares que constituyen las tradiciones de la caballeriĢa, en lugar de en las identidades culturales que implican sus etiquetas, la nocioĢn de las culturas mediterraĢneas del caballo puede ayudar mejor a los historiadores a entender maĢs a fondo la diplomacia y la estrategia militar a traveĢs de las fronteras cristiano-musulmanas
