Matuyama–Brunhes geomagnetic reversal record and associated key tephra layers in Boso Peninsula: extraction of primary magnetization of geomagnetic fields from mixed magnetic minerals of depositional, diagenesis, and weathering processes

open access: yesEarth, Planets and Space, 2022
We report paleomagnetic records of Matuyama–Brunhes geomagnetic polarity reversal and associated key tephra layers from the Early–Middle Pleistocene marine sedimentary succession in the Boso Peninsula. The outcrop is in Terasaki, Chiba, Japan and ~ 25 km

Magnetic Fabric: A Geophysical Approach for Identifying China's Neolithic Rammed Earth

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Accurate identification of rammed‐earth remains is essential for understanding early social complexity in Neolithic China. However, scientific methods for identifying rammed‐earth materials in Chinese prehistoric archeology remain limited, and identification still rely largely on field observations.

Views of Vidigal: negotiating opportunities and risks in a gentrifying favela in Rio de Janeiro Favela avec vue : négocier opportunités et risques dans un quartier en voie de gentrification à Rio de Janeiro

open access: yesJournal of the Royal Anthropological Institute, Volume 32, Issue 2, Page 554-574, June 2026.
The contested dynamics of slum gentrification in Rio de Janeiro came into focus during the brief period of relative peace brought by the pacification policy leading up to the 2016 Olympics. In this unprecedented moment, Rio's South Zone favela residents experienced a respite from the daily confrontations with police operations and drug trade violence ...

Emergence of the Food Balance Sheet: A History of A Traveling Idea L'émergence du bilan alimentaire : histoire d’une idée voyageuse

open access: yesContemporary Accounting Research, Volume 43, Issue 2, Page 1064-1090, Summer 2026.
ABSTRACT This article explores how accounting ideas travel to unfamiliar environments and instigate new modes of calculation therein. The empirical focus is on the food balance sheet, a key calculative technology in the realm of food security. Drawing on Said's four‐stage schema for analyzing the movement of theories and ideas, this investigation ...

Temperature-modulated magnetic skyrmion phases and transformations analysis from first-order reversal curve study

open access: yes, 2021
We performed a temperature-modulated first-order reversal curve (FORC) study on a Pt/Co/Fe/Ir magnetic stack that exhibited a magnetic phase transition from isolated skyrmions to skyrmion lattice with increasing temperature. Using in situ magneto-optical
