The Antarctic Impulsive Transient Antenna (ANITA) is a NASA long-duration balloon experiment with the primary goal of detecting ultra-high-energy (\(> 10^{18}\)eV) neutrinos via the Askaryan Effect. In the fourth ANITA mission, the Tunable Universal Filter Frontend (TUFF) boards were deployed for mitigation of narrow-band, anthropogenic noise with tunable, switchable notch filters. They contributed to a factor of 2.8 higher total instrument livetime in ANITA-4 compared to ANITA-3. A search for a diffuse flux of ultra-high-energy neutrinos was conducted using the data collected during the ANITA-3 flight with a new approach where the Antarctic ice area is sectioned off into bins and a search is performed with different thresholds in different bins. The binned analysis methods were extended to the development of a search for neutrinos from Gamma Ray Bursts, implementing constraints in time, and for the first time, in direction. Lower analysis thresholds were achieved in a feasibility search even when extending the search to include longer afterglow periods. Authored with osudiss-2.cls (v0.9.1)

We study the the birth of non farming enterprise in the developing world. We test if such activities are led by skills or are an ex-post income smoothing device for uninsured households. We find that farmers become entrepreneurs in response to negative productivity shocks to farming, while credit constraints do not seem to play a substantial role. Importantly, and consistently with irreversible investment or learning-by-doing, these reluctant entrepreneurs do not revert to full farming following new positive productivity shocks. These entrepreneurs are typically under performing entrepreneurs while they were above average farmers. This selection might contribute to the understanding of the dual phenomenon of low-productivity units coexisting in developing countries.

Este reporte tiene como objetivo principal conocer y comprender los comandos relacionados con el manejo de archivos y directorios, además de aquellos relacionados con el tema de rutas relativas y absolutas, listar contenidos y copiar texto entre archivos. El laboratorio se realiza a partir de las instrucciones dadas por el profesor, en las cuales se detalla cada paso y estos serán explicados en la sección de análisis de resultados. El manejo de estos comandos es importante para seguir comprendiendo los fundamentos básicos de la consola de Linux aprendidos en las primeras semanas de clases, con el fin de aplicarlos como un conjunto en un futuro.

General Game Playing (GGP) is the playing of a wide variety games you may have never seen before, by being told nothing but the rules of the game at run time. This sets it apart from traditional specific game players, like the famous chess player Deep Blue. Deep Blue can beat the world chess champion at chess however, it has absolutely no idea how to play checkers. It is designed for one particular game and cannot adapt to rule changes, and certainly cannot play entirely different games. The goal of this project is to create a program that will play a wide variety of 2d games given descriptions of their rules without the creator of the program having ever known of the games. This report will cover the design and implementation of this project, as well as the background research performed and reflections on the outcome of the project.
