The chiral torsional anomaly and the Nieh-Yan invariant with and without boundaries

Journal of High Energy Physics
There exists a long-standing debate regarding the torsion contribution to the 4d chiral anomaly of a Dirac fermion. Central to this debate is the Nieh-Yan anomaly, which has been considered ill-defined and a regularization artifact.

Exploring the Materiality of Data Breach Disclosures on the Australian Stock Exchange

Abacus, Volume 62, Issue 3, Page 673-697, September 2026.
This study examines Australian Stock Exchange (ASX) data breach announcements to provide insights into the extent and nature of data breach disclosures, as well as the costs, particularly to stakeholder relationships. Using a dataset of all data breach‐related announcements on the ASX, we identify a lack of data breach disclosure and, where disclosures

Light-ray sum rules and the c-anomaly

Journal of High Energy Physics
In a four-dimensional quantum field theory that flows between two fixed points under the renormalization group, the change in the conformal anomaly ∆a has been related to the average null energy.

Do universal owners behave like universal owners? The emergence of a financial sector norm

American Business Law Journal, Volume 63, Issue 3, Page 235-263, Fall 2026.
Abstract The past few years have seen a surge in scholarship on universal ownership, systematic stewardship, and system‐level investing. These concepts describe the reality that large diversified owners of capital own a more or less representative slice of the market and therefore must concern themselves with systemic risks to the financial system as a

Generalized families of QFTs

Journal of High Energy Physics
RG flows and IR phases of QFTs can be constrained by generalized symmetries and their anomalies. Broken symmetries act on the space of coupling constants of families of theories, and can also have IR-constraining family anomalies.

Charnia and other late Ediacaran macrofossils preserved in turbiditic deposits of the Indreelva Member (Finnmark, Norway)

Palaeontology, Volume 69, Issue 5, September/October 2026.
Abstract The fossil genus Charnia is emblematic of the evolutionary expansion of metazoans during the late Ediacaran. The first discovery of Charnia specimens from Scandinavia is here reported, alongside new examples of Palaeopascichnus, Aspidella‐type holdfasts, and possible scratch circles.

On monopoles in low energy string theory and non-abelian particle trajectories [PDF]

, 1997
This thesis is mainly concerned with monopoles. First, the existence of monopoles and their behaviour in the Yang-Mills-Higgs theories, and in parallel, the instanton solutions of the Yang-Mills fields are explained.

Anomaly-free spectra, unimodular lattices and 6D R-symmetry gauged supergravity

Journal of High Energy Physics
We study the classification problem for anomaly-free 6D 𝒩 = (1, 0) supergravities with a gauged abelian R-symmetry and one tensor multiplet. We present eleven new models with gauge group G non−Abelian × U(1) R that satisfy the local Green-Schwarz ...

Zebrafish as a practical and convenient model for the study of photodynamic and photothermal therapy of solid tumors: A scoping review

Photochemistry and Photobiology, Volume 102, Issue 5, Page 1060-1078, September/October 2026.
Zebrafish provide a high‐throughput, optically transparent platform for cancer and drug screening. Their ~80% genetic homology, xenograft compatibility, and transgenic strains enable targeted photosensitizer screening, real‐time ROS and tumor imaging, and mechanistic assays, while fish embryo acute toxicity (FET) and in vitro tests streamline toxicity ...

Syndromic Convergence in Aquaculture Disease Management: A Critical Review of Climate‐Pathobiome Interactions, Diagnostic Frameworks, and Knowledge Gaps

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Syndromic convergence (SyCo) reframes aquaculture disease as the synergistic product of climate‐driven stressors, pathobiome communities, and host immune compromise, not single pathogens. A five‐criterion scoring matrix, composite early warning index, and three‐layer intervention framework together operationalize this shift toward predictive ...
