Reciprocal Non-Relativistic Decoupling Limits of String Theory and M-Theory
Neil Lambert, Joseph Smith
It has recently been realised that there are supersymmetry-preserving non-relativistic decoupling limits associated with each half-BPS object in String Theory and M-Theory. We argu…
How Quality Affects Deep Neural Networks in Fine-Grained Image Classification
Joseph Smith, Zheming Zuo, Jonathan Stonehouse +1
In this paper, we propose a No-Reference Image Quality Assessment (NRIQA) guided cut-off point selection (CPS) strategy to enhance the performance of a fine-grained classification…
A Note on the Perturbative Expansion of the Schwinger Model on
Joseph Smith
The Schwinger model is perhaps the simplest non-trivial exactly-solvable QFT. In this note we examine the perturbative structure of the theory on the sphere and show that its quant…
An Augmentation-based Model Re-adaptation Framework for Robust Image Segmentation
Zheming Zuo, Joseph Smith, Jonathan Stonehouse +1
Image segmentation is a crucial task in computer vision, with wide-ranging applications in industry. The Segment Anything Model (SAM) has recently attracted intensive attention; ho…
Non-Relativistic M2-Branes and the AdS/CFT Correspondence
Neil Lambert, Joseph Smith
A non-relativistic limit of the AdS/CFT correspondence is studied in the context of M2-branes. On the field theory side this corresponds to a near-BPS limit of ABJM that localises…
The M5-Brane Limit of Eleven-Dimensional Supergravity
Eric Bergshoeff, Neil Lambert, Joseph Smith
We construct the M5-brane limit of eleven-dimensional supergravity. The resulting action is invariant under Galilean boosts and has a local scale symmetry. We also consider the lim…
