    Chalcolithic stamp seals from Tepe Gheshlagh, and a look into their application in ownership and exchange systems by Mahnaz Sharifi, Abbas Motarjem

    Published 2025-08-01
    “…With a descriptive-analytical method, an attempt was made to expound on Gheshlagh’s glyptic assemblage that attest to the existence of an ownership system and commercial exchanges. A structural analysis of the glyptic iconography suggested that each of the linear, circular, or repeating patterns were less mere personal insignias intended to exclude the possibility of alteration or forgery than they were marks belonging to a pre-literate system where each sign/symbol stood for individual commodity types that were transported or exchanged as such. …”

    Multipolar Anisotropy in Anomalous Hall Effect from Spin-Group Symmetry Breaking by Zheng Liu, Mengjie Wei, Wenzhi Peng, Dazhi Hou, Yang Gao, Qian Niu

    Published 2025-07-01
    “…The traditional view of the anomalous Hall effect (AHE) in ferromagnets is that it arises from the magnetization perpendicular to the measurement plane and that there is a linear dependence on the latter. Underlying such a view is the thinking that the AHE is a time-reversal symmetry breaking phenomenon and can therefore be treated in terms of a power series in the magnetic order. …”

    Published 2025
    “…The construction industry significantly contributes to environmental degradation,with many structures exhibiting high carbon footprints throughout their construction processes and lifespans.Activities such as cement hydration and other commoncon-struction practices substantially influence environmental conditions overtime,necessitating a critical evaluation of material and design choices.This study reported the environmental impact of fly ash(FA),which is largely used to enhance concrete strength.A prediction of two end point indicators,that is,global warming potential(GWP)and CO2 emission using soft computing methods are presented,which are particularly effective for handling complex,non linear relationships in environmental data.To achieve this, two machine learning approaches,the random forest(RF)and decision tree(DT)models,are employed to assess the environ- mental impact of structural materials and designs.Two data sets were obtained from reputable databases,including ResearchGate, Science Direct, Semantic Scholar,and Mendeley Data.The models are trained to explore the potential for optimizing structural designs and material selection stominimize environmental impacts.Feature importance is analyzed using Shapley values,providing insights into the most influential factors affecting GWP and CO2 emission Model performance is evaluated using R2 and root mean square error(RMSE) metrics. …”
