Understanding spatial and temporal evolution of progressive excavation damage zone in granitic rocks – development of a novel mine-by and laboratory experimental framework at the BedrettoLab

Abstract. The brittle damage around tunnels in the form of spalling is common in massive crystalline rocks subjected to high in-situ stresses. Understanding the short-term development and long-term evolution of the Excavation Damage Zone (EDZ) is particularly important for deep g...

Deployed quantum key distribution network: further, longer and more users

Abstract Entanglement-based quantum links are intended to become the backbone of future quantum networks, enabling secure communication between distant cities. Implementing such networks requires addressing multiple practical challenges: time synchronization, interferometric syst...

Planktonic foraminifera iodine ∕ calcium ratio: is it a proxy for dissolved oxygen in the ocean?

Abstract. Direct observations indicate a declining trend in ocean oxygen concentrations, which is not quantitatively captured by models. The complexity of oxygenation variability, linked to both physical and biochemical parameters, must be investigated across different modern cli...
