hiv_transmission: HIV transmission network (1988-2001)
A set of networks of HIV transmissions between people through sexual, needle-sharing, or social connections, based on combining 8 datasets collected from 1988 to 2001. Metadata includes test results of several diseases, as well as demographic variables such as age, ethnicity, and gender. Networks come in two flavors: egodyads and altdyads. Egodyads are the network among study-participants and their direct partners. Altdyads are the…

Hessian operators, overdetermined problems, and higher order mean curvatures: symmetry and stability results
It is well known that there is a deep connection between Serrin's symmetry result -- dealing with overdetermined problems involving the Laplacian -- and the celebrated Alexandrov's Soap Bubble Theorem (SBT) -- stating that, if the mean curvature $H$ of the boundary of a smooth bounded connected open set $\Om$ is constant, then $\Om$ must be a ball. One of the main aims of the paper is to extend the study of such a connection to the broader case of overdetermined problems for Hessian operators a…

Fast Geographic Routing in Fixed-Growth Graphs
In the 1960s, the social scientist Stanley Milgram performed his famous "small-world" experiments where he found that people in the US who are far apart geographically are nevertheless connected by remarkably short chains of acquaintances. Since then, there has been considerable work to design networks that accurately model the phenomenon that Milgram observed. One well-known approach was Barab{á}si and Albert's preferential attachment model, which has small diameter yet lacks an algorithm tha…

Trying to use old USB hard drives I found in a drawer as additional local backup storage is not going well.
One disconnects after some time. Another stays connected but has a bad block.

Robust design of bicycle infrastructure networks

Robust design of bicycle infrastructure networks - Scientific Reports
Promoting active mobility like cycling relies on the availability of well-connected, high-quality bicycle networks. However, expanding these networks over an extended planning horizon presents one of the most complex challenges in transport science. This complexity arises from the intricate interactions between infrastructure availability and usage, such as network spillover effects and mode choice substitutions. In this paper, we approach the problem from two perspectives: direct optimization …
