The vast amounts of data that are now available provide new opportunities to social science researchers, but also raise huge privacy concerns for data subjects. Differential privacy offers a way to balance the needs of both parties. But how?

Courier problems comprise a set of recently proposed combinatorial optimization problems, which are inspired by some novel requirements in railway wagon scheduling. In these problems, scheduling strategies of some mobile couriers are considered. These mobile couriers initially reside at some fixed location. They are assigned some duties of commodity transfer between different pairs of locations. The scenario may be static or dynamic. The motivation is to optimize the movement of the couriers over the constraint of the traversed path or the associated cost. We discuss here some varieties of the courier problems formalized on graphs and address the potential methods of their solution.

Unambiguous representation of mathematics is crucial for communications among humans or among computer systems. OpenMath is a standard aimed at supporting a semantically rich interchange of mathematics among varied computational software tools such as computer algebra systems, theorem provers, and tools for visualizing or editing mathematical text. MathML is a W3C Recommendation for the encoding of mathematics 'on the web' which also includes mechanisms for encoding mathematical semantics. We introduce each of these two languages and describe their relationships.
