A recent theory of a compressible Fermi-liquid like state at Landau level filling factors ν = 1/q or 1 − 1/q, q even, is reviewed, with emphasis on the basic physical concepts.

We compare the energies of different electron solids, such as bubble crystals with triangular and square symmetry and stripe phases, to those of correlated quantum liquids in partially filled intermediate Landau levels. Multiple transitions between these phases when varying the filling of the top-most partially filled Landau level explain the observed reentrance of the integer quantum Hall effe...

The filler/matrix interface in fiber-reinforced polymer composites is critical in controlling load transfer from the matrix to the fiber, failure mechanisms, and degradation. It is not clear, however, how the mechanisms of load transfer in traditional composites apply to nanofiber-filled polymers. This paper is focused on understanding the reinforcement mechanisms in multiwalled carbon nanotube...

The current medical students' training on communication skills does not completely fulfil its purpose, since it often lacks attention to the various aspects essential for developing an empathic capacity. Besides having an active component in empathy, cognitive and affective aspects are of equal importance. Integration of arts and humanities courses into the curriculum might bridge this gap. Emp...

PEN-Ivory is a pen-based computer system that uses structured data entry for creating patient progress notes. Users make simple gestures such as circles, lines, and scratch-outs to enter medical findings from a controlled vocabulary. The result of an interaction with PEN-Ivory is a computer-generated patient progress note in English prose. We designed PEN-Ivory's user interface in a principled ...

One of the goals of ubiquitous computing is to allow users to naturally access various digital functions with daily physical artifacts like paper. Existing paper-digital integration systems, however, either sacrifice inherent paper flexibility or support very limited digital functionality on paper. This thesis explores how to enable rich pen-based interaction on paper without loss of the origin...

This paper describes the introduction of a new interaction paradigm to augmented reality applications. The everyday tool handling experience of working with pen and notebooks is extended to create a three dimensional two-handed interface, that supports easy-to-understand manipulation tasks in augmented and virtual environments. In the design step we take advantage from the freedom, given by our...

We understand the real world in terms of objects: When we look at a picture or our surroundings, or when we close our eyes and listen, we organize the information arriving from the outside world in terms of attributes for perceived, independent objects. “Independence” can refer to physical separability (the pen on my desk), behavioral autonomy (the hissing steam valve on the radiator), or more ...

The DMFT index, which represents caries experience as recommended by the World Health Organization (clinical examination without radiographs), was compared with a modified DMFT index with radiographs. The purpose was to evaluate how much the DMFT index underestimates the need for restorative care. A cohort of 376 young adults (eighteen to twenty years old) was examined from March 2003 to Decemb...

BACKGROUND Past research has found that playing a classic prosocial video game resulted in heightened prosocial behavior when compared to a control group, whereas playing a classic violent video game had no effect. Given purported links between violent video games and poor social behavior, this result is surprising. Here our aim was to assess whether this finding may be due to the specific game...
