Investigating Cytotoxicity and Defense functions of bacteriophage Larva genes in host Mycobacterium smegmatis
It is estimated that approximately 75% of gene functions within any given phage cluster remain unknown. Two phage traits that can be measured phenotypically were investigated: cytotoxicity, which causes host cell lysis, and...

Bicycle helmet wearing is associated with closer overtaking by drivers
There is a body of research on how driver behaviour might change in response to bicyclists’ appearance. In 2007, Walker published a study suggesting motorists drove closer on average when passing a bicyclist if the rider wore a...

Faraday pilot-wave dynamics
A millimetric droplet bouncing on the surface of a vibrating fluid bath can self-propel by virtue of a resonant interaction with its own wave field. This system represents the first known example of a pilot-wave system of the...

The effect of a helmet on cognitive performance is, at worst, marginal
The present study looked at the effect of a helmet on cognitive performance under demanding conditions, so that small effects would become more detectible. Nineteen participants underwent 30 min of continuous visual vigilance...
Mixing time of random walk on dynamical random cluster
We study the mixing time of a random walker who moves inside a dynamical random cluster model on the d-dimensional torus of side-length n. In this model, edges switch at rate μ between open and closed, following a Glauber...

DDX5 potentiates HIV-1 transcription as a co-factor of Tat.
BACKGROUND: HIV-1 does not encode a helicase and hijacks those of the cell for efficient replication. We and others previously showed that the DEAD box helicase, DDX5, is an essential HIV dependency factor. DDX5 was recently...

Random walks with preferential relocations and fading memory
Consider a stochastic process that behaves as a d-dimensional simple and symmetric random walk, except that, with a certain fixed probability, at each step, it chooses instead to jump to a given site with probability...

Achieving robustness to aleatoric uncertainty with heteroscedastic Bayesian optimisation
Ryan-Rhys Griffiths, Alexander A Aldrick, Miguel Garcia-Ortegon, Vidhi Lalchand, Alpha A Lee

Abstract: Bayesian optimisation is a sample-efficient search methodology that holds great promise for accelerating drug and materials discovery programs. A frequently-overlooked modelling consideration in Bayesian optimisation...

Random walks on dynamical percolation
We study the behavior of random walk on dynamical percolation. In this model, the edges of a graph \(G\) are either open or closed and refresh their status at rate \(\mu \) while at the same time a random walker moves on \(G\)...
Sexually selected sentinels? Evidence of a role for intrasexual competition in sentinel behavior.
Although the evolutionary mechanisms that favor investment in cooperative behaviors have long been a focus of research, comparatively few studies have considered the role that sexual selection may play. For example, evolutionary...
