Statistical detection of selfish mining in proof-of-work blockchain systems

Scientific Reports
The core of many cryptocurrencies is the decentralised validation network operating on proof-of-work technology. In these systems, validation is done by so-called miners who can digitally sign blocks once they solve a computationally-hard problem ...

Coherence‐Gated Wrapped‐Phase InSAR With Matrix‐Based Uncertainty Diagnostics for Burial‐Mound Hotspot Ranking (Sicily, Italy)

Archaeological Prospection, EarlyView.
ABSTRACT Burial mounds are key elements of Mediterranean funerary landscapes, but in intensively cultivated coastal plains their low‐relief expression is easily obscured by ploughing, levelling and rapidly changing surface conditions, making single‐date observations unreliable.

Optimal dosing for vascular anomalies paediatric patients with population pharmacokinetic model of sirolimus

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Sirolimus is currently used off‐label for paediatric patients with vascular anomalies. However, the optimal dosage regimen for paediatric patients remains controversial. This study aimed to determine the optimal dosing regimen of sirolimus in these patients using a population pharmacokinetic (PK) model.
