Approximately optimal experimental design for heteroscedastic Gaussian process models

This paper presents a greedy Bayesian experimental design criterion for heteroscedastic Gaussian process models. The criterion is based on the Fisher information and is optimal in the sense of minimizing parameter uncertainty for likelihood based estimators. We demonstrate the validity of the criterion under different noise regimes and present experimental results from a rabies simulator to demonstrate the effectiveness of the resulting approximately optimal designs.

La coppia nel tango argentino fra tradizione e palcoscenico

Questo studio cerca di individuare e descrivere gli elementi che contraddistinguono la coppia del tango dal punto di vista coreografico e strutturale e vedere in che modo questi fondamenti vengono trasposti sul palcoscenico. Come introduzione viene presentato il percorso della coppia lungo la storia approfondendo i rapporti e le influenze reciproci fra il ballo e i diversi contesti sociali e norme di tipo morale dei singoli momenti storici. Viene affrontata anche la dimensione tecnica del ballo e i codici che la governano attraverso le testimonianze di consolidati ballerini e maestri della generazione attuale e quelle precedenti. In conclusione vengono fornite le analisi di tre spettacoli teatrali prodotti da quattro coreografi diversi che mettono in chiaro gli approcci distintivi nella rappresentare scenica del tango e nel suo utilizzo come linguaggio teatrale.

Studio della correlazione fra la percentuale di cellule neoplastiche mutate in EGFR e la risposta a farmaci TKI nell'adenocarcinoma polmonare

Il gene EGFR e' un marcatore molecolare fondamentale per determinare la sensibilita' o meno ai farmaci inibitori delle tirosin-chinasi (TKI) in pazienti affetti da adenocarcinoma polmonare. Lo scopo del lavoro e' di determinare se la percentuale di cellule neoplastiche mutate in EGFR correli con la risposta ai farmaci TKI. Sono stati analizzati 18 casi; di ogni caso e' stato analizzato il gene EGFR (esoni 18, 19, 20 e 21) mediante Next Generation Sequencing (NGS). La quantita' di cellule neoplastiche presenti nell'area analizzata e' stata valutata da un patologo, su un vetrino colorato con Ematossilina-Eosina, e tale quantita' e' stata normalizzata alla percentuale di alleli mutati rilevata mediante NGS. E' stata rilevata una correlazione fra la percentuale di cellule neoplastiche mutate in EGFR e la risposta ai TKI, ed e' stato osservato che pazienti con una percentuale di cellule neoplastiche mutate al di sopra del 56% presentano una migliore "overall survival" rispetto ai pazienti con una percentuale inferiore. I dati suggeriscono che, oltre al valore predittivo, la definizione della percentuale di cellule neoplastiche mutate in EGFR potrebbe avere un valore prognostico.

Pollen and macrofossil profiles from six cores in Illinois, U.S.A

Pollen analysis of Wisconsinan sediments from eleven localities in northern and central Illinois, combined with the results of older studies, allows a first general survey of the vegetational changes in Illinois during the last glaciation. In the late Altonian (after 40,000 B.P.), pine was already the most prevalent tree type in northern Illinois. Probably because of the influence of the last Altonian ice advance to northern Illinois, pine migrated to the south and reached south-central Illinois, which was at that time a region of prairie, with oak and hickory trees in favorable sites. Likewise in the late Altonian, spruce appeared in northern Illinois. Spruce also expanded its area to the south during the Wisconsinan, reaching south-central Illinois only after 21,000 B.P., in the early Woodfordian. Deciduous trees (predominantly oak) were present in south-central Illinois throughout the Wisconsinan. Their prevalence decreased to the north. The vegetation during the different subdivisions of the last glacial period in Illinois was approximately as follows: Late Altonian: Pine/spruce forest with some deciduous trees in northern and central Illinois; prairie and oak/hickory stands in south-central Illinois; immigration of pine. Farmdalian: Pine/spruce forest in central Illinois; deciduous trees and pine in south-central Illinois, with areas of open vegetation, perhaps similar to the present-day transition of prairie to forest in the northern Great Plains. Woodfordian: Northern and central Illinois ice covered; in south central Illinois, spruce and oak as dominant tree types, but also pine and grassland. During the Woodfordian, pine and spruce disappeared again from south-central Illinois, and oak/hickory forest and prairie again prevailed. The ice-free areas of northern Illinois become populated temporarily with spruce, but later there is proof of deciduous forest in this region. Pollen investigations in south-central Illinois have shown convincingly that deciduous trees could survive relatively close (less than 60 km) to the ice margin. Therefore the frequently presented view that arctic climatic conditions prevailed in North America during the last glaciation far south of the ice margin can be refuted for the Illinois area, confirming the opinion of other authors resulting from investigations of fossil mollusks and frost-soil features. The small number of localities investigated still permits no complete reconstruction of the vegetation zones and their possible movements in Illinois. During the Altonian and Farmdalian in Illinois, a vegetational zonation probably existed similar to that of today in North America. As the ice pushed southward as far as 39° 20' N. lat in the early Woodfordian, this zonation was apparently broken up under the influence of a relatively moderate climate. In any case, the Vandalia area, which was only about 60 km south of the ice, was at that time neither in a tundra zone nor in a zone of boreal coniferous forest.

Las potencias subregionales en el sistema internacional de posguerra fría: ¿nuevos actores en la política internacional?

En trabajos anteriores, hemos avanzado en la identificación y diferenciación de tres categorías de potencias: potencias mundiales, potencias medias y potencias regionales. Pero, más allá de las potencias mundiales y las potencias medias que se encuentran en el centro del sistema-mundial, y las potencias regionales que se ubican en la semiperiferia, ¿es posible hablar de potencias que se encuentren en la periferia? Como se trata de Estados periféricos, ¿pueden ser calificados como “potencias”? ¿En qué radicaría su relevancia y envergadura? Dichas “potencias” ¿pueden ser agrupadas en una nueva categoría? De ser así ¿qué características compartirían? El objetivo de este documento es proponer una nueva  categoría de potencias en el sistema internacional: las potencias subregionales.
