Public health in the United States began as a largely urban phenomenon, dating back to the late 1700s. In those days, public health was mostly concerned with issues such as sanitation and communicable diseases, which were of greater concern in areas with higher population density. By the late 1800s, however, it was apparent that the country's population was becoming more mobile and communicable...

in this paper, we present a binary-linear optimization model to prevent the spread of an infectious disease in a community. the model is based on the remotion of some connections in a contact network in order to separate infected nodes from the others. by using this model we nd an exact optimal solution and determine not only the minimum number of deleted links but also their exact positions. ...

Housing reform in urban China has introduced market mechanisms into a previously welfare-oriented housing system. Although microlevel factors such as household characteristics begin to shape housing behavior in urban China as is the case in the West, macrolevel constraints and opportunities defined by not only housing stocks and housing markets but also local government behaviors continue to be...

Thework of this thesis has focused on creating computational models of developing neurons. Three different but related areas of research have been studied how cells make connections, what influences the shape of these connections and how neuronal network behaviour can be influenced by local interactions. In order to understand how cells make connections I simulated the dynamics of the neuronal ...

A physical system should be in a local equilibrium if it cannot be distinguished from a global equilibrium by “infinitesimally localized measurements”. This seems to be a natural characterization of local equilibrium, however the problem is to give a precise meaning to the qualitative phrase “infinitesimally localized measurements”. A solution is suggested in form of a Local Equilibrium Conditi...

The disciplines covered by the proposed Initiativkolleg include differential geometry, groups of symmetries, (non-linear) PDEs, singularities, and mathematical relativity. The local expertise together with the obvious synergies between these fields has the potential of creating a group of students who have close interaction both among themselves and with the existing research groups. The organi...

There has been much debate in recent years about the quality of local public education in the United States. Much of this discussion has centered around the apparent underperformance of children in basic areas like reading, math, and English as reflected by low scores on standardized achievement exams relative to their international peers and the appropriate level of educational spending. This ...
