We show that there exists a family of groups Gn and nontrivial irreducible representations ρn such that, for any constant t, the average of ρn over t uniformly random elements g1, . . . , gt ∈ Gn has operator norm 1 with probability approaching 1 as n→∞. More quantitatively, we show that there exist families of finite groups for which Ω(log log |G|) random elements are required to bound the nor...

Climate change is now recognized as a prime challenge of the 21st century. It is increasingly clear that there is a need to take action in order to adapt specific buildings to changing circumstances, in a cost-effective way. This paper presents the results of the first step of an EPSRC-funded research project that aims to manage the thermal risks in buildings subject to climate change, employin...

in the current engineering practices, buildings are commonly designed for an effective lifetime of 50 years. this lifetime can increase the cost of buildings with short lifetimes and can reduce the safety level of buildings with large lifetimes. in this paper, a “service-life factor” has been defined. applying this factor into the nominal values of live, earthquake, wind, and snow loads, the ef...

ntimicrobianas empíricas en infecciones producidas por este atógeno. No podemos obviar la posibilidad de colonización de reserorios, pero tampoco podemos descartar la implicación de este icroorganismo en bacteriemias descritas5, dado que algunos atógenos desencadenantes de sepsis, pueden colonizar reservoios cutáneos (port-a-cath) y generar biofilms. Concluimos, que la secuenciación para la ide...

S e presentan dos métodos que se pueden utilizar como alternativas al GWAS para localizar QTLs en ganado. El primero se centra en el análisis de secuencias de homocigosis (runs of homozygosity, ROH) en grupos de animales (p.ej. casos y controles); el segundo es un método de remuestreo basado en la frecuencia de inclusión de los SNP en modelos predictivos. Las ROH se aplicaron a la identificació...

The impact of three treatment strategies for Trypanosoma evansi control on horse mortality in the Brazilian Pantanal based on four size categories of cattle ranches is explored. The region's 49,000 horses are indispensable to traditional extensive cattle ranching and T. evansi kills horses. About 13% of these horses would be lost, annually, due to T. evansi if no control were undertaken. One pr...

InSAR data are used to recognise large industrial building complexes. Such buildings often show salient regular patterns of strong scatterers on their roofs. A previous segmentation which uses the intensity, height and coherence information extracts building cues. Strong scatterers are filtered by a spot detector and localised by a cluster formation. Strong scatterers are grouped in rows by a p...

Mientras que los anillos incompletos asintomáticos pueden mantenerse bajo vigilancia9,10. La asociación de RTS y anillo vascular completo es poco frecuente. Es importante que ante la sospecha de anomalías cromosómicas los pacientes sean valorados por el cardiólogo pediatra para su diagnóstico. Las técnicas de imagen no invasivas son de ayuda para la delimitación de la anatomía precisa y la plan...
