Large deviation theory for diluted Wishart random matrices

Modern computing technology has brought about the era of Big Data, and a host of new challenges concerning how to analyse high-dimensional data for problems ranging from studies of climate to genetics, biomedical imaging to economics. Read more

Baillie Gifford sponsors LML Economics project

We are delighted to share the news that Baillie Gifford has become LML’s first corporate sponsor, donating £1 million over four years to support our research into economics. We are grateful for this generous philanthropy, which will help us accelerate progress in this ground-breaking scientific programme.

Switching dynamics in atmospheric flow

The jet stream is a band of air that flows around the Earth at high-altitude, moving West to East in mid-latitude regions. This so-called “zonal” flow typically has cyclones and anticyclones embedded within it, which last for a few days. Read more

Small Cities Face Greater Impact From Automation

Cities are modern society’s hubs for economic productivity and innovation, and now accommodate over half of the world’s population. As job migration is the leading factor in urbanization, policymakers are increasingly concerned about the likely impact of artificial intelligence and automation on city employment. Read more

Scaling Behaviour in Mathematical Models of Aggregation

The rings of Saturn are among the most spectacular structures in our solar system, made up of innumerable fragments of ice and rock ranging in size from metres to millimetres. The stability of the rings is a matter of some debate among planetary scientists. Read more

Sampling the Dynamical Properties of Northern Hemisphere Atmospheric Fields Over the Past 60 Years

Solar radiation and the earth’s rotation are the primary drivers of large-scale atmospheric motions, while turbulence adds a layer of complexity at small scales. This picture is further complicated by ocean–land interactions, vegetation, anthropocentric forcing, and the hydrological cycle. Read more

Summary of the Discussion on Large-Scale Atmospheric Extreme Weather Events in Stockholm

Extreme, high-impact weather events have serious social and economic consequences, and have garnered widespread scientific and media attention. Understanding their drivers and improving their prediction is therefore a topic of crucial societal and economic value, where the interests of academia, policy makers and private stakeholders converge.

Empirical limits in the estimation of financial risk measures

Following the financial crisis of 2007-2008, governments and financial regulators all over the globe pledged to reduce risk in the financial system. Many have raised capital requirements on banks, while others have tried to force financial institutions to be less opaque in communications with their clients. Read more

A Novel Model to Simulate Biological Cell Migration

In recent years evidence has accumulated that single biological cells often move in a way that is unlike Brownian motion, a paradigmatic model of random dynamics. Instead, cells migrate faster and exhibit so-called superdiffusion. This article reports on a new method to efficiently simulate superdiffusively moving cells. Read more
