Low‐Field Magnetic Resonance Imaging of the Late Gestation Cervix and Birth Outcome Correlation: A Prospective Cohort Study

BJOG: An International Journal of Obstetrics &Gynaecology, Volume 133, Issue 6, Page 1166-1173, May 2026.
ABSTRACT Objective To use low‐field MRI to produce reconstructions and 3D models of the cervix and to automate measurements for correlation with demographics and birth outcomes. Design Prospective cohort study. Setting KCL Advanced Imaging Centre, St Thomas's Hospital.

T Cell Receptor Repertoires Across the Continuum of Vascular, Myocardial, and Age‐Related Diseases

Immunological Reviews, Volume 339, Issue 1, May 2026.
ABSTRACT Cardiovascular diseases (CVD) are shaped by a complex interplay with immune mechanisms. In particular, the distinct roles of antigen‐specific T cell mechanisms are emerging as critical determinants across a broad spectrum of conditions, ranging from atherosclerosis, myocardial infarction (MI), heart failure (HF), and myocarditis. Because these

A unified approach to L p $L^{p}$ Hardy and Rellich-type inequalities in Euclidean and non-Euclidean settings

Journal of Inequalities and Applications
We present a unified and concise method for establishing L p $L^{p}$ Hardy and Rellich inequalities for a broad class of subelliptic operators of divergence type.

Lorentzian homogeneous structures with indecomposable holonomy

Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract For a Lorentzian homogeneous space, we study how algebraic conditions on the isotropy group affect the geometry and curvature of the homogeneous space. More specifically, we prove that a Lorentzian locally homogeneous space is locally isometric to a plane wave if it admits an Ambrose–Singer connection with indecomposable, non‐irreducible ...

Synthesis and Magnetism of Co 2 III $_{2}^{III}$ Co 5 II $_{5}^{II}$ and Co 2 III $_{2}^{III}$ Co 6 II $_{6}^{II}$ Complexes, and the Role of the Free Choice of Local Coordinate Frames for Interpreting Magnetic Parameters

European Journal of Inorganic Chemistry, Volume 29, Issue 12, 24 April 2026.
In order to rationalise the magnetic properties of a newly synthesised Co2III$_{2}^{III}$Co6II$_{6}^{II}$ coordination cluster it was found essential to exploit the freedom to choose the local coordinate frames for describing the high‐spin CoII centres.

Non-compact gauge groups, tensor fields and Yang-Mills-Einstein amplitudes

Journal of High Energy Physics
Scattering amplitudes in Yang-Mills-Einstein theories have been investigated mostly for compact gauge groups. While non-compact gauge groups are not physically viable in Yang-Mills theory, non-compact gaugings feature prominently in the supergravity ...
