Topological terms and anomaly matching in effective field theories on ℝ3 × 𝕊1. Part I. Abelian symmetries and intermediate scales

open access: yesJournal of High Energy Physics, 2021
We explicitly calculate the topological terms that arise in IR effective field theories for SU(N) gauge theories on ℝ3 × 𝕊1 by integrating out all but the lightest modes. We then show how these terms match all global-symmetry ’t Hooft anomalies of the UV

Mesiodens in a permanent and mixed dentition

open access: yesЭндодонтия Today, 2020
Supernumerary teeth are considered one of the most significant tooth abnormalities in the initial and early stages of mixed and primary dentition. They are of great importance to dentists and parents because of the problems that they can cause. Mesiodens

Multilevel Anomaly Detection for Mixed Data [PDF]

open access: yesarXiv, 2016
Anomalies are those deviating from the norm. Unsupervised anomaly detection often translates to identifying low density regions. Major problems arise when data is high-dimensional and mixed of discrete and continuous attributes. We propose MIXMAD, which stands for MIXed data Multilevel Anomaly Detection, an ensemble method that estimates the sparse ...

Dynamics from symmetries in chiral SU(N) gauge theories

open access: yesJournal of High Energy Physics, 2020
The symmetries and dynamics of simple chiral SU(N) gauge theories, with matter Weyl fermions in a two-index symmetric tensor and N + 4 anti-fundamental representations, are examined, by taking advantage of the recent developments involving the ideas of ...

Seasonal variability of the upper warmwatersphere in the Canary Basin

open access: yesScientia Marina, 2001
Two years of periodic XBT data, along seven transects covering the Canary Basin, were examined to analyse the seasonal cycle of the upper layers of the warmwatersphere.

Anatomy of a Cyclonic Eddy in the Kuroshio Extension Based on High-Resolution Observations

open access: yesAtmosphere, 2019
Mesoscale eddies are common in the ocean and their surface characteristics have been well revealed based on altimetric observations. Comparatively, the knowledge of the three-dimensional (3D) structure of mesoscale eddies is scarce, especially in the ...

Gravitational Anomalies in Noncommutative Field Theory [PDF]

open access: yesarXiv, 2004
Gravitational axial and chiral anomalies in a noncommutative space are examined through the explicit perturbative computation of one-loop diagrams in various dimensions. The analysis depend on how gravity is coupled to noncommutative matter fields. Delbourgo-Salam computation of the gravitational axial anomaly contribution to the pion decay into two ...
