Duality anomalies in linearized gravity

Physical Review D
Classical linearized gravity admits a dual formulation in terms of a higher-rank tensor field. However, proposing a prescription for the instanton sectors of linearized gravity and its dual, we show that they may be . The duality anomaly is obtained by resolving the dual graviton theories into vector-valued p-form electrodynamics and is controlled by ...

A Prospection‐Led Archaeological Investigation of a Picenian and Roman Necropolis in Corinaldo (Marche, Italy)

Archaeological Prospection, EarlyView.
ABSTRACT This paper presents the results of an integrated archaeological and geophysical investigation conducted between 2018 and 2024 at the newly discovered Picenian and Roman necropolis of Contrada Nevola (Corinaldo, Marche, Central Italy), identified in the framework of development‐led archaeology. The research strategy combined aerial photography,

Non-Newtonian gravity or gravity anomalies? [PDF]

Geophysical measurements of G differ from laboratory values, indicating that gravity may be non-Newtonian. A spherical harmonic formulation is presented for the variation of (Newtonian) gravity inside the Earth.

“Hands‐On” white matter anatomy: Using Air Anatomy gestures and tractography on simple brain sections to enhance teaching of white matter directions

Anatomical Sciences Education, EarlyView.
Abstract Teaching white matter (WM) anatomy to undergraduates is challenging. This is partly because WM fibers are oriented intricately and Klingler's dissection, the gold standard method used to demonstrate it, often requires time, advanced anatomical knowledge, and refined dissection skills.

Comparative Study on the Accuracy of Terrestrial and Global Gravitational Models (GGMs) Gravity Anomalies for Akure Environs, Ondo State, Nigeria

Indonesian Journal of Earth Sciences
Spherical harmonic expansion is a mathematical method used to describe Earth's gravity field, derived from potential coefficients observed both on Earth's surface and from space. The International Centre for Gravity Earth Models (ICGEM) publishes Global

Surface ship gravity data obtained on board the icebreaker Shirase

Antarctic Record, 2006
A ship-borne gravity survey on board the icebreaker Shirase has been continuously conducted since JARE-27 (the 27th Japanese Antarctic Research Expedition); about 17 years of gravity data have been accumulated. Although data obtained from JARE-27 to JARE-
