Background studies for acoustic neutrino detection at the South Pole
2011
The detection of acoustic signals from ultra-high energy neutrino interactions is a promising method to measure the tiny flux of cosmogenic neutrinos expected on Earth. The energy threshold for this process depends strongly on the absolute noise level in the target material. The South Pole Acoustic Test Setup (SPATS), deployed in the upper part of four boreholes of the IceCube Neutrino Observatory, has monitored the noise in Antarctic ice at the geographic South Pole for more than two years down to 500 m depth. The noise is very stable and Gaussian distributed. Lacking an in-situ calibration up to now, laboratory measurements have been used to estimate the absolute noise level in the 10 to …
An interface protection system based on an embedded metrology system platform
2021
Abstract The aim of this work is to present an interface protection system (IPS) for Distributed Generators (DG) and Energy Storage Systems (ESS). The new prototype of IPS guarantees standard protection requirements, in terms of both voltage and frequency measurement accuracies and trip times. Moreover, it has the additional functionalities of implementing a communication link between the Distribution System Operator (DSO) and the DG and ESS Inverter. The new IPS is based on a smart meter platform with an integrated power line communication modem. Moreover, it has also an integrated metrology section. Experimental tests will show how this last feature allows a significant reduction of the m…
Intra-Tumour Genetic Heterogeneity and Prognosis in High-Risk Neuroblastoma
2021
Simple Summary Neuroblastoma (NB) is the most common extra-cranial solid paediatric cancer and is responsible for 15% of childhood cancer deaths. Patients with NB are characterized by presenting a very heterogeneous clinic (inter-tumoural heterogeneity) and also both spatial and temporal intra-tumour heterogeneity (ITH) reflected in their genetic aberrations, which may be the consequence of the coexistence of different microenvironments within the tumour. Applying pangenomic techniques to detect genomic aberrations in different biopsies (solid and liquid) of high risk NB (HR-NB) we have detected spatial ITH in a surprisingly high percentage (almost 40%) of the studied cohort. Moreover, a po…
Soluciones quimiométricas para optimizar el análisis de parámetros químicos en aguas
2002
El proyecto de tesis "Soluciones quimiométricas para optimizar el análisis de parámetros químicos en aguas" ha sido planeado y realizado con el objetivo de la propuesta de soluciones analíticas en el estudio de la calidad del agua. Se estudió la situación del medioambiente, la relación de los recursos hídricos y la contaminación, los tipos de análisis de aguas, la legislación sobre la calidad del agua, los métodos analíticos existentes, los métodos de control de calidad de los resultados, el papel de la quimiometría en el análisis medioambiental y las tendencias en el análisis del agua.En base a estas consideraciones generales, se evaluaron diferentes temas de interés en la tesis: las neces…
Optimizing Sequential Systemic Therapies for Advanced Hepatocellular Carcinoma: A Decision Analysis
2020
Background: An optimal sequential systemic therapy for advanced hepatocellular carcinoma (HCC) has not been discovered. We developed a decision model based on available clinical trials to identify an optimal risk/benefit strategy for sequences of novel systemic agents. Methods: A Markov model was built to simulate overall survival (OS) among patients with advanced HCC. Three first-line (single-agent Sorafenib or Lenvatinib, and combination of Atezolizumab plus Bevacizumab) followed by five second-line treatments (Regorafenib, Cabozantinib, Ramucirumab, Nivolumab, Pembrolizumab) were compared in fifteen sequential strategies. The likelihood of transition between states (initial treatment, ca…
