Reciprocity and success in academic careers
Since the 1950s, assessments of the quality and effectiveness of scientific research have increasingly rested on quantitative measures based on publication citations. Read more →
A semi-parametric spatiotemporal Hawkes-type point process model with periodic background for crime data
Criminologists try to predict crime with a number of methods, such as “hot-spotting” – making maps of locations where crimes tend to occur – and epidemiological techniques based on the assumption that the local risk of crime rises temporarily after a crime occurs. Read more →
Testing Randomness in Quantum Mechanics
Monte Carlo experiments use computation and repeated random sampling to obtain numerical estimates for various natural or mathematical processes. Read more →
Polarization of opinions in a network with two communities
The recent study of large data sets has revealed the key network structures behind many biological, social, and technological processes. Read more →
Continuous vs. Discontinuous Transitions in the D-Dimensional Generalized Kuramoto Model: Odd D is different
In 1975, Yoshiki Kuramoto introduced a simple model to describe the collective dynamics of a set of interacting oscillators. In the model, each oscillator has a natural frequency, and is coupled equally to all other oscillators. Read more →
Biological movement and the Lévy flight hypothesis
How do animals move through their environment as they search for resources, or try to satisfy other natural goals? Over the past two decades, researchers have examined this question using real world data for organisms such as albatross, marine predators and bees, often finding a pattern of many short or mid-scale movements punctuated by occasional long flights or excursions.

Space junk, algorithmic hatred and meaningless jobs – a few recent essays
Here are links to a few recent articles by LML Fellow Mark Buchanan. Read more →
Identifying the recurrence patterns of non-volcanic tremors using a 2-D hidden Markov model
Tectonic movements create stress within the Earth’s crust, which gets released in sudden earthquakes, but also in less dramatic slow slip events. Such events are sometimes accompanied by so-called non-volcanic tremors – weak seismic signals of extended duration along major faults. Read more →
Final presentations from the 2018 LML Summer School now online
The LML Summer School for 2018 ran from mid-July to mid-August and was a great success, with eight students collaborating on projects supervised by LML Fellows. The students made their final presentations on 17 August, and these are now available online, links given below. Read more →
Do environmental concerns affect commuting choices? Hybrid choice modelling with household survey data
Addressing climate change is among the top challenges facing governments around the world, requiring drastic reductions of greenhouse gas emissions. In part this will be through new technologies but progress will also require encouraging significant changes in day-to-day human behaviour. Read more →
