Breaking conditional symmetry in automated constraint modelling with CONJURE [PDF]

open access: yes, 2014
This work was supported by UK EPSRC EP/K015745/1. Jefferson is supported by a Royal Society University Research Fellowship.Many constraint problems contain symmetry, which can lead to redundant search.

Arginine methylation as a regulatory ratchet in cancer: From substrate selection to malignant‐state stabilization

open access: yesMolecular Oncology, EarlyView.
Arginine methylation can be viewed as a persistence‐prone post‐translational modification regulated by a network of PRMTs. Competitive and compensatory interactions among PRMTs can redistribute methylation across substrate pools shaped by sequence, structural, spatial, and environmental layers, reinforcing RNA‐processing, chromatin, and signaling ...

Carrollian Yang-Mills theory

open access: yesJournal of High Energy Physics, 2023
By doing a small c (speed of light) expansion of SU(N) Yang-Mills fields, we construct two different electric and two different magnetic sectors actions of Carrollian Yang-Mills theory.

Planons and their Carroll-Galilei symmetries

open access: yesJournal of High Energy Physics
We study the dynamics of planons, particles whose mobility is restricted to a plane, through the classification of coadjoint orbits and unitary irreducible representations of the centrally extended planon group.

Multipole charge conservation and implications on electromagnetic radiation

open access: yesJournal of High Energy Physics, 2017
It is shown that conserved charges associated with a specific subclass of gauge symmetries of Maxwell electrodynamics are proportional to the well known electric mul-tipole moments.

Space-Time Symmetry and Space-Time Ontology

open access: yesJournal for History of Mathematics, 2015
In spite of various attempts to characterize the ontological status of space-time, Newtonian substantivalism and Leibnizian relationism, what is really at issue in the controversy between the two parties is by no means clear. This essay argues that from the perspective of space-time symmetries, classical space-time can be unambiguously classified as ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Empirical consequences of symmetries [PDF]

open access: yes, 2011
It is widely recognised that 'global' symmetries, such as the boost invariance of classical mechanics and special relativity, can give rise to direct empirical counterparts such as the Galileo-ship phenomenon.

Path integral games with de Sitter α-vacua

open access: yesJournal of High Energy Physics
The α-vacua are a 1-parameter family of quantum field vacua in de Sitter space which are invariant under the isometry group SO(1, d). In this work give a path integral construction of the de Sitter α-vacua. We explain that these states can be prepared by

Zwanziger’s pairwise little group on the celestial sphere

open access: yesJournal of High Energy Physics, 2021
We generalize Zwanziger’s pairwise little group to include a boost subgroup. We do so by working in the celestial sphere representation of scattering amplitudes. We propose that due to late time soft photon and graviton exchanges, matter particles in the
