The emerging closeness between correlated spin systems and error-correcting codes enables us to use coding theoretical techniques to study physical properties of manybody spin systems. This thesis illustrates the use of classical and quantum coding theory in classifying quantum phases arising in many-body spin systems via a systematic study of stabilizer Hamiltonians with translation symmetries...

Weak gravitational lensing is a promising tool for the study of the mass distribution in the Universe. Here we report some partial results that show how lensing maps can be used to differentiate between cosmological models. We pay special attention to the role of noise and smoothing. As an application, we use mock convergence fields constructed from N-body simulations of the large-scale structu...

In the present article we use a chat conversations’ corpus to study the process of resolving language problems. Our corpus includes chat conversations which took place between LSP students engaged in correcting errors in their peers’ summaries. The participants worked in groups and used the W indows Messenger program for communication within the group. Their task also included making use of ele...

Understanding the performance impact of compiler optimizations on superscalar processors is complicated because compiler optimizations interact with the microarchitecture in complex ways. This paper analyzes this interaction using interval analysis, an analytical processor model that allows for breaking total execution time into cycle components. By studying the impact of compiler optimizations...

The use of computer games has been a popular but controversial issue. Dickey (2005) points out that instructional technologists are prepared to borrow techniques from various fields of media such as film, television and comics. Computer games, however, are ignored in terms of advancing new methods for instructional models despite a body of research on computer games and the availability of edut...

CANCER ECOGENETICS Are cancer epidemiologists ready for molecular geneticists? This could have been the subtitle of a workshop, 'Genetic and Environmental Factors in Etiologic Studies of Cancer,' a European regional scientific meeting of the International Epidemiology Association, held in Reykjavik, Iceland, 13-15 June 1986. Under scrutiny was the intersection of two apparently contradictory tr...

Abstract Computer vision systems are employed in a variety of high-impact applications. However, making them trustworthy requires methods for the detection potential biases their training data, before models learn to harm already disadvantaged groups downstream Image data typically represented via extracted features, which can be hand-crafted or pre-trained neural network embeddings. In this wo...
