Gradient‐Free Online Learning of Subgrid‐Scale Dynamics With Neural Emulators

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract In this paper, we propose a generic algorithm to train machine learning‐based subgrid parametrizations online, that is, with a posteriori loss functions, but for non‐differentiable numerical solvers. The proposed approach leverages a neural emulator to approximate the reduced state‐space solver, which is then used to allow gradient propagation

Distinct T-cell receptor (TCR) gene segment usage and MHC-restriction between foetal and adult thymus

open access: yeseLife
Here, we sequenced rearranged TCRβ and TCRα chain sequences in CD4+CD8+ double positive (DP), CD4+CD8- single positive (SP4) and CD4-CD8+ (SP8) thymocyte populations from the foetus and young adult mouse.

A Foot in Both Camps: The Civilian Suppliers of the Army in Roman Britain

open access: yesTheoretical Roman Archaeology Journal, 2018
The civilian attendants and suppliers of the Roman army—those who were attached economically and voluntarily to the Roman military—are an important and understudied group. This article explores their roles and experiences during the Principate in Britain.

Brain‐Mimetic Mapless Navigation Framework Integrating Visual Streams and Entorhinal‐Hippocampal‐Prefrontal Circuits

open access: yesCAAI Transactions on Intelligence Technology, Volume 11, Issue 4, Page 1231-1253, August 2026.
ABSTRACT Efficient autonomous navigation in complex and unstructured environments without pre‐existing maps remains a significant challenge for mobile robotics. Drawing inspiration from rodent neural architectures, this study proposes a brain‐mimetic mapless navigation framework for mobile robots.

Traj-MAE: Masked Autoencoders for Trajectory Prediction

open access: yes, 2023
Trajectory prediction has been a crucial task in building a reliable autonomous driving system by anticipating possible dangers. One key issue is to generate consistent trajectory predictions without colliding.

Resistance is Useless! Culture, Status, and Power in the Civitas Icenorum

open access: yesTheoretical Roman Archaeology Journal, 2018
The interpretation of past status and hierarchy often relies on modern concepts of social stratification. Despite much debate over the structure of Late Iron Age and early Romano-British societies, there remains a tendency to refer uncritically to the ...

L3 Regressive Transfer: A Study of Null Objects in the Basque and Spanish Grammars of Advanced L3 English Speakers

open access: yesInternational Journal of Applied Linguistics, Volume 36, Issue 3, Page 2565-2578, August 2026.
ABSTRACT Regressive transfer has been a subject that has not been extensively researched in the field of third language acquisition. This study aims to examine the extent to which a highly advanced knowledge of a third language (L3) affects the first language (L1) and the second language (L2) of early bilinguals in light of the Differential Stability ...

The Construction, Use, and Discard of Female Identities: Interpreting Spindle Whorls at Vindolanda and Corbridge

open access: yesTheoretical Roman Archaeology Journal, 2018
Spindle whorls are one of the most durable traces of the textile craft in the archaeological record. They can be found in copious quantities and diverse types in forts and extramural settlements on the Romano British northern frontier.

How Structural Subtleties Modulate Excited‐State Lifetimes in Cyclometalated Cobalt(III) Complexes: Nonadiabatic Molecular Dynamics Study

open access: yesJournal of Computational Chemistry, Volume 47, Issue 20, July 30, 2026.
Nonadiabatic trajectory simulations unravel the origin of different relaxation times scales observed for two Co(III) complexes, bearing different alkyl groups at their ligands. ABSTRACT Ultrafast excited‐state dynamics of two Co(III) complexes, bearing different alkyl groups (Co1: Methyl, Co2: Ethyl) at the nitrogen of the imidazole ligand, are ...
