Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

CPT embedded in countinuous symmetries

Nuclear Physics B
In the case of a complex scalar field ϕ, we show that discrete CPT symmetries can be embedded in continuous symmetries. Moreover, we identify the conserved quantities corresponding to these symmetries.

Discrete Symmetries CP, T, CPT

EPJ Web of Conferences, 2016
The role of Symmetry Breaking mechanisms to search for New Physics is of highest importance. We discuss the status and prospects of the Discrete Symmetries CP, T, CPT looking for their separate Violation in LHC experiments and meson factories.

Zero-form and one-form symmetries of the ABJ and related theories

Journal of High Energy Physics, 2022
The zero-form and one-form global symmetries of the Aharony-Bergman-Jafferis (ABJ) and related theories, with at least N $$ \mathcal{N} $$ = 6 supersymmetry in three dimensions, are examined in detail.

Empirical consequences of symmetries [PDF]

, 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.

Non-Abelian discrete R symmetries [PDF]

, 2013
We discuss non-Abelian discrete R symmetries which might have some conceivable relevance for model building. The focus is on settings with $$ \mathcal{N}=1 $$ supersymmetry, where the superspace coordinate transforms in a one-dimensional representation ...

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Discrete gauge groups in F-theory models on genus-one fibered Calabi-Yau 4-folds without section

Journal of High Energy Physics, 2017
We determine the discrete gauge symmetries that arise in F-theory compactifications on examples of genus-one fibered Calabi-Yau 4-folds without a section.

Perfect Symmetries [PDF]

, 2007
While empirical symmetries relate situations, theoretical symmetries relate models of a theory we use to represent them. An empirical symmetry is perfect if and only if any two situations it relates share all intrinsic properties. Sometimes one can use a

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

FEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.
