Online conference on Ergodicity Economics, January 2021
The mathematical concepts of randomness were first developed in economics in the 17th century, primarily in the context of problems of gambling and games of chance. Read more
Optical Tweezers: A Comprehensive Tutorial from Calibration to Applications
A highly-focused laser beam can be used to trap microscopic particles. In this technique – known as optical tweezers – forces arise near the focal spot due to radiation pressure of the light beam (acting along the beam direction) and gradient forces which pull the particle towards the high-intensity focal spot.

Seminar Series: COVID-19
Along with colleagues Jorge Velasco-Hernandez and David Sanders, LML External Fellow Isaac Pérez Castillo has organised a series of seminars to be held throughout the rest of the year on topics linked to the COVID-19 pandemic. Read more
A New Method for Imaging Seismic Quiescence and Its Application to the Mw = 8.3 Kurile Islands Earthquake on 15 November 2006
The seismic quiescence hypothesis asserts that the number of small earthquakes decreases in and around the focal area of a great earthquake near to its time of occurrence. Read more
Model checking for hidden Markov models
Hidden Markov models (HMMs) were first introduced in the late 1960s, and later applied widely in areas including speech recognition, bioinformatics, finance and seismology. Read more
The Echo Index and multistability in input-driven recurrent neural networks
Recurrent neural networks (RNNs) are non-autonomous dynamical systems driven by input, the behaviour of which depend on both model parameters and inputs to the system. Read more
The SAFER geodatabase for the Kathmandu Valley: Geotechnical and geological variability
The Kathmandu Valley — the most developed and populated region in Nepal – is seismically active and has experienced recurring destructive earthquakes. Read more
Nonstationary Background Seismicity Rate and Evolution of Stress Changes in the Changning Salt Mining and Shale-Gas Hydraulic Fracturing Region, Sichuan Basin, China
Many earthquakes have been induced by human activities, including wastewater disposal, geothermal production, gas injection and hydraulic fracturing (HF). Read more
Non-Equilibrium Dynamics and Weakly Broken Integrability
Scientists still lack a fundamental understanding of how and when complex many-body systems out of equilibrium will relax back to thermal equilibrium. Empirically, many systems do relax readily, justifying many of the core approximations of thermodynamics. Read more
Giant leaps and long excursions: fluctuation mechanisms in systems with long-range memory
Many random processes lack memory – that is, the probability distribution for change over any time interval depends on the present state of the process but remains independent of how it behaved previously. Read more
