Global anomalies in 8d supergravity
Journal of High Energy Physics, 2022 We study gauge and gravitational anomalies of fermions and 2-form fields on eight-dimensional spin manifolds. Possible global gauge anomalies are classified by spin bordism groups Ω 9 spin BG $$ {\varOmega}_9^{\mathrm{spin}}(BG) $$ which we determine by ...

Proof of dispersion relations for the amplitude in theories with a compactified space dimension
Journal of High Energy Physics, 2020 The analyticity properties of the scattering amplitude in the nonforward direction are investigated for a field theory in the manifold R 3,1 ⨂ S 1.

Curious QNEIs from QNEC: new bounds on null energy in quantum field theory
Journal of High Energy PhysicsWe derive new families of quantum null energy inequalities (QNEIs), i.e. bounds on integrated null energy, in quantum field theories in two and higher dimensions. These are universal, state-independent lower bounds on semi-local integrals of 〈T vv 〉, the

Odd dimensional nonlocal Liouville conformal field theories
Journal of High Energy Physics, 2022 We construct Euclidean Liouville conformal field theories in odd number of dimensions. The theories are nonlocal and non-unitary with a log-correlated Liouville field, a Q $$ \mathcal{Q} $$ -curvature background, and an exponential Liouville-type ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Graft‐versus‐host disease (GvHD) remains one of the most significant complications of hematopoietic stem cell transplantation (HSCT). Abatacept, a selective T‐cell costimulation modulator, is a relatively novel prophylactic agent, though pediatric data remain limited.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

T T ¯ $$ T\overline{T} $$ deformations in curved space from 4D Chern-Simons theory
Journal of High Energy Physics, 2022 In this paper, we shed new light onto T T ¯ $$ T\overline{T} $$ -deformations by engineering them on 2D surface defects, supporting chiral and antichiral CFT’s, in a 4D Chern-Simons bulk. This approach is motivated by various connections between T T ¯ $$

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.
