Simulation of astronomical aspects of Middle Neolithic circular ditch systems [PDF]
ArchéoSciences, 2009 Introduction The oldest Middle European monuments (approx. 4850/4750 – 4550/4500 BC) were presented in the Lower Austrian County Exhibition at Heldenberg in 2005 (Daim & Neubauer, 2005). The Middle Neolithic circular ditch systems, or Kreisgrabenanlagen (KGA), are known all over Middle Europe. These wooden monuments form a first pan-European phenomenon,

Photometric Accuracy of Deconvolved Simulated Astronomical Images
The Astrophysical Journal, 2005 A study of the photometric accuracy of deconvolved astronomical images was undertaken by processing two simulated images with several well-known algorithms. The simulations consisted of an image of a simple star field and an image of an active galactic nucleus (AGN).

VLBI Network SIMulator: An Integrated Simulation Tool for Radio Astronomers
, 2018 In this paper we introduce a software package, the Very Long Baseline Interferometry Network SIMulator (VNSIM), which provides an integrated platform assisting radio astronomers to design the Very Long Baseline Interferometry (VLBI) experiments and evaluate the network performance with a user-friendly interface. Though VNSIM is motivated to be designed

DeepSurveySim: Simulation Software and Benchmark Challenges for Astronomical Observation Scheduling
DeepSurveySim: Simulation Software and Benchmark Challenges for Astronomical Observation Scheduling, 2023 Modern astronomical surveys have multiple competing scientific goals. Optimizing the observation schedule for these goals presents significant computational and theoretical challenges, and state-of-the-art methods rely on expensive human inspection of simulated telescope schedules.

Advanced Functional Materials, EarlyView.A defect‐engineered Ag/Gd2O3:Nb2O5/Pt rare earth composite oxide memristor enables stable multilevel reservoir states through pulse driven conductance modulation. Experimentally measured device responses are incorporated into a device aware reservoir computing framework for CIFAR‐100 image classification, highlighting the potential of rare earth ...

Advanced Functional Materials, EarlyView.Here, we develop a high‐throughput algorithm that accelerates the elucidation of phase diagrams of topological spin textures using limited computational resources at high numerical accuracy. Applying this framework to the van der Waals magnet CrSBr, we unveiled a hierarchy of previously unknown topological textures (domain‐wall bimerons, bimeron chains,

Current‐Driven Chirality Detection of Magnetic Textures in Cylindrical Nanowires
Advanced Functional Materials, EarlyView.Current‐assisted anisotropic magnetoresistance measurements in individual Ni/Au cylindrical nanowires enable detection of vortex chirality near Au segments and selective magnetic reversal in defined wire sections at magnetic fields lower than the propagation field. This approach provides a simple, cost‐effective, and non‐invasive method for probing and

Merger-tree-based Galaxy Matching: A Comparative Study across Different Resolutions
The Astrophysical JournalWe introduce a novel halo/galaxy matching technique between two cosmological simulations with different resolutions, which utilizes the positions and masses of halos along their subhalo merger tree. With this tool, we conduct a study of resolution biases

Spatially contrasted response of Devonian anoxia to astronomical forcing [PDF]
Climate of the PastThe Devonian period, spanning from 419 to 359 million years ago, was marked by a warmer-than-present climate and recurring ocean anoxic events, with evidence increasingly suggesting a link between these events and astronomical forcing.
