On the provenance of stonepaste bodies of tiles from Takht-e Soleyman, northwestern Iran

Petrofabrics and compositional data from thirty-three stonepaste bodies of 13th-14th century architectural tiles retrieved at Takht-e Soleyman (northwestern Iran) were compared with those of fifty-four stonepaste bodies from Kashan, Isfahan, Rayy, Soltaniyeh and Yazd, in order to shed light on the provenance of the tiles from Takht-e Soleyman. The petrofabrics showed two main groups of stonepaste bodies within the shards from Takht-e Soleyman with the largest group most certainly originating ...

Responsabilità algoritmica e architettura giuridica : Verso una governance distribuita del rischio

The algorithmic revolution has disrupted the foundational pillars of tradi- tional legal responsibility. Artificial intelligence systems – especially those based on deep learning and opaque architectures – operate without moral agency or intentionality, yet they produce both normative and material effects. This essay investigates the crisis of the classical paradigm of liability – grounded in linear causality, subjective fault, and imputability – and proposes a systemic reconfigu- ratio...

Dall’equità formale all’equità algoritmica : Per una capability-sensitive AI governance

The increasing use of algorithmic decision-making in important areas such as education, welfare and justice requires us to reconsider what fairness means. Reducing fairness to the formal impartiality of code can perpetuate structural inequalities that are divorced from real-world conditions. Building on the ideas of John Rawls and Amartya Sen, this paper puts forward a model of capability-sensitive algorithmic governance that integrates legal duties, adaptive technical architectures and ...

Early stages of Palaeolithic rock art in southern Iberia. Malaga area

We present a record of caves in southern Iberia in which Palaeolithic graphic manifestations are made up of a variety of signs, among which fingerings and punctuations, traces, pigment projections on geological formations, or coloured stains applied to the surface or edges of the speleothems predominate. They have been included in the concept of ‘aniconic horizon’. The uranium series dating in Cueva de Ardales has confirmed the remarkable antiquity of some of these manifestations. We present ...

Ultra-trace analysis of U and Th in organic liquid scintillators with high sensitivity

Rare event searches demand extremely low background levels, necessitating ever-advancing screening techniques to enhance sensitivity. Liquid scintillators are highly attractive as detector media due to their inherent radiopurity and scalability in mass. In this work, we present a screening procedure to measure ultra-trace concentrations of natural contaminants – 238U and 232Th – with sensitivities at the 10-15 g/g level. Our method combines neutron activation analysis with radiochemical ...
