Defragmenting Beethoven: Sound appropriation as bridge between classical tradition and electroacoustic music

This thesis serves as a written companion for two artistic-based research products built upon the concept of appropriation as connecting bridge between music technology and the classical tradition of music composition. The first artistic work is a set of 9 pieces called "Collages Vol 2", a continuation of a first release meant to be an exploratory work for the present research. The second work is the sound interaction design, and the creation of two compositions for the Network of Intelligent Sound Agents, or "NOISA", built at the Sound and Physical Interaction Research Group from the Department of Media, Aalto University. After providing context and a short survey of influences on music appropriation, I made a comprehensive documentation of each of the pieces created for this thesis, describing form, content, compositional approach and sound processing in a systematic way. I investigated on the diverse forms of appropriation as a technique for electroacoustic music composition. The most influential references for my work are documented in this written work: From the historical approach of appropriation to borrowing in music of the XX century and recent times; including a description of the first volume of my original Collages. Later on, I described my second collection of Collages and the utilisation of appropriation theories in the context of NOISA, a music interface for live performance. Finally, there is a section dedicated to a discussion featuring a commentary of a number of reviews of "Collages” preceding a closing segment with conclusions and further plans to expand this research in the future

Perspectivas literarias: traducción e intertextualidad

En este libro hemos reunido un conjunto de trabajos que exploran temas relacionados con la traducción literaria y con los estudios literarios desde una perspectiva múltiple y comparada, pues creemos que, en estos tiempos, es valioso detenerse a analizar experiencias complejas con respecto a las prácticas literarias que permiten la comunicación intercultural, ya que ésta es una vía para cuestionar visiones nacionalistas que, en ocasiones, tienden a achatar el panorama en lugar de reconocer la hibridez y la heterogeneidad de los discursos literarios. Se trata de analizar estos temas desde distintos ángulos, tales como la traducción, las intertextualidades temáticas, la formación de traductores, la perspectiva de los lectores, la construcción del canon por distintas instancias culturales y los estudios comparados

New scheme of intermittent benznidazole administration in patients chronically infected with Trypanosoma cruzi: Clinical, parasitological, and serological assessment after three years of follow-up

In a pilot study, we showed that the intermittent administration of benznidazole in chronic Chagas disease patients resulted in a low rate of treatment suspension and therapeutic failure, as assessed by quantitative PCR (qPCR) at the end of treatment. Here, a 3-year posttreatment follow-up study of the same cohort of patients is presented. The treatment scheme consisted of 12 doses of benznidazole at 5 mg/kg of body weight/day in two daily doses every 5 days. Parasite load, Trypanosoma cruzi-specific antibodies, and serum chemokine levels were measured prior to treatment and after a median follow-up of 36 months posttreatment by DNA minicircle kinetoplastid and nuclear DNA satellite sequence qPCR methods, conventional serological techniques, a Luminex-based assay with recombinant T. cruzi proteins, and a cytometric bead array. At the end of follow-up, 14 of 17 (82%) patients had negative qPCR findings, whereas three of 17 (18%) had detectable nonquantifiable findings by at least one of the qPCR techniques. A decline in parasite-specific antibodies at 12 months posttreatment was confirmed by conventional serological tests and the Luminex assays. Monocyte chemoattractant protein 1 levels increased after treatment, whereas monokine induced by gamma interferon levels decreased. New posttreatment electrocardiographic abnormalities were observed in only one patient who had cardiomyopathy prior to treatment. Together, these data strengthen our previous findings by showing that the intermittent administration of benznidazole results in a low rate of treatment suspension, with treatment efficacy comparable to that of a daily dose of 5 mg/kg for 60 days.Fil: Alvarez, María Gabriela.

Early impact of the COVID-19 pandemic on paediatric cancer care in Latin America

Although previous studies have suggested that the complications and mortality rate related to COVID-19 are substantially lower in the paediatric population,1 it is reasonable to consider that children with underlying conditions such as cancer will be at increased risk of severe disease...Fil: Vasquez, Liliana.

Intensive Care Unit Admission after Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy. Is It Necessary?

Introduction. Cytoreductive surgery (CS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is a new approach for peritoneal carcinomatosis. However, high rates of complications are associated with CS and HIPEC due to treatment complexity; that is why some patients need stabilization and surveillance for complications in the intensive care unit. Objective. This study analyzed that ICU stay is necessary after HIPEC. Methods. 39 patients with peritoneal carcinomatosis were treated according to strict selection criteria with CS and HIPEC, with closed technique, and the chemotherapy administered were cisplatin 25 mg/m2/L and mitomycin C 3.3 mg/m2/L for 90-minutes at 40.5°C. Results. 26 (67%) of the 39 patients were transferred to the ICU. Major postoperative complications were seen in 14/26 patients (53%). The mean time on surgical procedures was 7.06 hours (range 5−9 hours). The mean blood loss was 939 ml (range 100–3700 ml). The mean time stay in the ICU was 2.7 days. Conclusion. CS with HIPEC for the treatment of PC results in low mortality and high morbidity. Therefore, ICU stay directly following HIPEC should not be standardized, but should preferably be based on the extent or resections performed and individual patient characteristics and risk factors. Late complications were comparable to those reported after large abdominal surgery without HIPEC

Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory

The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared to the data of the surface detector stations of the Observatory, which provide well-calibrated information on the cosmic-ray energies and arrival directions. The response of the radio stations in the 30 to 80 MHz regime has been thoroughly calibrated to enable the reconstruction of the incoming electric field. For the latter, the energy deposit per area is determined from the radio pulses at each observer position and is interpolated using a two-dimensional function that takes into account signal asymmetries due to interference between the geomagnetic and charge-excess emission components. The spatial integral over the signal distribution gives a direct measurement of the energy transferred from the primary cosmic ray into radio emission in the AERA frequency range. We measure 15.8 MeV of radiation energy for a 1 EeV air shower arriving perpendicularly to the geomagnetic field. This radiation energy -- corrected for geometrical effects -- is used as a cosmic-ray energy estimator. Performing an absolute energy calibration against the surface-detector information, we observe that this radio-energy estimator scales quadratically with the cosmic-ray energy as expected for coherent emission. We find an energy resolution of the radio reconstruction of 22% for the data set and 17% for a high-quality subset containing only events with at least five radio stations with signal.Comment: Replaced with published version.

Measurement of the Radiation Energy in the Radio Signal of Extensive Air Showers as a Universal Estimator of Cosmic-Ray Energy

We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Auger Observatory, we obtain a radiation energy of 15.8 \pm 0.7 (stat) \pm 6.7 (sys) MeV for cosmic rays with an energy of 1 EeV arriving perpendicularly to a geomagnetic field of 0.24 G, scaling quadratically with the cosmic-ray energy. A comparison with predictions from state-of-the-art first-principle calculations shows agreement with our measurement. The radiation energy provides direct access to the calorimetric energy in the electromagnetic cascade of extensive air showers. Comparison with our result thus allows the direct calibration of any cosmic-ray radio detector against the well-established energy scale of the Pierre Auger Observatory.Comment: Replaced with published version.

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
