How Bugs Make Lassos

Bugs don't make worms kill.

How bugs kill bugs: progress and challenges in bacteriocin research.

A Biochemical Society Focused Meeting on bacteriocins was held at the University of Nottingham on 16-18 July 2012 to mark the retirement of Professor Richard James and honour a scientific career of more than 30 years devoted to an understanding of the biology of colicins, bacteriocins produced by Escherichia coli. This meeting was the third leg of a triumvirate of symposia that included meeting...

How Developers Diagnose and Repair Software Bugs

How do practitioners debug computer programs? In a retrospective study with 180 respondents and an observational study with 12 practitioners, we collect and discuss data on how developers spend their time on diagnosis and fixing bugs, with key findings on tools and strategies used, as well as highlighting the need for automated assistance. To facilitate and guide future research, we provide a h...

Distinguished minimal toplogical lassos

A classical result in distance based tree-reconstruction characterizes when for a distance D on some finite set X there exist a uniquely determined dendrogram on X (essentially a rooted tree T = (V,E) with leaf set X and no degree two vertices but possibly the root and an edge weighting ω : E → R≥0) such that the distance D(T,ω) induced by (T,ω) on X is D. Moreover, algorithms that quickly reco...

How Brain Cells Make Memories

Remembering a lot of things at the same time is difficult. As an experiment, read these numbers: 07041776. Then, close your eyes and try to say them aloud, in order. How did you do? We would guess that you remembered around half of the numbers. Now, try again but think of the same numbers as a date: 07-04-1776. Did you remember more of the numbers this time? You just demonstrated something call...
