We present a tutorial review of our quantum state resolved experiments designed to study gas-surface reaction dynamics. The combination of a molecular beam, state specific reactant preparation by infrared laser pumping, and ultrahigh vacuum surface analysis techniques make it possible to study chemical reactivity at the gas-surface interface in unprecedented detail. We describe the experimental...

Understanding the folding of the human genome is a key challenge of modern structural biology. The emergence of chromatin conformation capture assays (e.g., Hi-C) has revolutionized chromosome biology and provided new insights into the three dimensional structure of the genome. The experimental data are highly complex and need to be analyzed with quantitative tools. It has been argued that the ...

Type Ia supernovae (SNe Ia) are the largest thermonuclear explosions in the Universe. Their light output can be seen across great distances and has led to the discovery that the expansion rate of the Universe is accelerating. Despite the significance of SNe Ia, there are still a large number of uncertainties in current theoretical models. Computational modeling offers the promise to help answer...

The morphology of thin films has been extensively studied in the last years. The properties of a thin film are closely related to its microstructure, especially to its morphology and surface roughness. Optical reflectivity, conductivity, and porosity are characteristics that depend on the film structure. The knowledge of atomistic details of the thin film growth process is useful for the develo...

One of the central issues in the study of discourse anaphora is concerned with the problem of anaphoric distribution in discourse, namely how to account for the choice of a particular referential/anaphoric form at a particular point in discourse. Needless to say, anaphoric distribution in discourse is a very complex phenomenon, involving, among other things, structural, cognitive and pragmatic ...

background and objectives: low fruit/vegetable (fv) diet seems to be a global public health problem. the trans-theoretical stages of change model have long been considered a useful interventional approach in lifestyle modification programs. the aim of this study was to find the most important intermediating factors of fv consumption in mashhad, iran. materials and methods: in this cross-section...

I feel particularly honored by this invitation to deliver the opening address at the annual meeting of the European Association for Theoretical Computer Science because I am not a computer scientist. Thus I must attribute my presence here to the importance of the field of graph theory as a useful mathematical model in your field. Similarly I was astounded by the invitation to give the opening l...
