Leveraging Big Multitemporal Multisource Satellite Data and Artificial Intelligence for the Detection of Complex and Invisible Features: The Case of Extensive Irrigation Mapping

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...

TAMNet: Temporal and adaptive‐frequency network with MixStyle for cross‐region oil and fluid production forecasting

open access: yesDeep Underground Science and Engineering, EarlyView.
This paper presents temporal and adaptive‐frequency network with MixStyle (TAMNet), a deep time‐series modeling framework for accurate and robust multi‐well oil productivity forecasting. TAMNet integrates transformer and long short‐term memory architectures to capture both short‐ and long‐term temporal dependencies, enhanced by a temporal gate unit ...

MRI Diffusion Tensor Image Analysis Along the Perivascular Space: Effects of Mean Tract Orientation Divergence

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The diffusion tensor image analysis along the perivascular space (DTI‐ALPS) index is an established term, and ongoing research aims to explore underlying mechanisms. Hypothesis DTI‐ALPS measures are influenced by subject‐specific orientational differences of the projection and association fibers. Study Type Prospective.

CUDA-LLM: LLMs Can Write Efficient CUDA Kernels

open access: yesCoRR
Large Language Models (LLMs) have demonstrated strong capabilities in general-purpose code generation. However, generating the code which is deeply hardware-specific, architecture-aware, and performance-critical, especially for massively parallel GPUs, remains a complex challenge.

Predicting Statistical Signatures of Collective Emission in Disordered Color Center Ensembles

open access: yesLaser &Photonics Reviews, EarlyView.
We present an efficient simulation framework for modeling collective emission in disordered ensembles of quantum emitters. The low computational complexity enables large‐scale Monte Carlo simulations. Applied to SiV−${\rm SiV}^{-}$ clusters, it predicts thresholded superradiant bursts set by emitter number and quantum efficiency, as well as interaction‐
