Robust quantum state engineering through coherent localization in biased-coin quantum walks [PDF]

EPJ Quantum Technology, 2018
We address the performance of a coin-biased quantum walk as a generator for non-classical position states of the walker. We exploit a phenomenon of coherent localization in the position space - resulting from the choice of small values of the coin ...

Nuovi indicatori di sbilanciamento e prevedibilità nei disegni sequenziali randomizzati: confronti fra 'biased coin designs' diversi [PDF]

Statistica, 2007
Efron's (1971) Biased Coin Design is a well-known randomization technique of sequential clinical trials for comparing two treatments in the absence of prognostic factors that helps neutralize selection bias while keeping the experiment fairly balanced ...

Determination of the ED90 of Remimazolam Bolus Dose for Preventing Emergence Delirium in Children with Sevoflurane Anesthesia: A Dose-Finding Study Using Biased-Coin Design Up-and-Down Sequential Method [PDF]

Drug Des Devel Ther
Purpose Emergence delirium (ED), a psychomotor agitation state, has a high incidence in children under sevoflurane anesthesia. Single-bolus administration of remimazolam can effectively reduce ED occurrence, similar to continuous infusion.

Determination of the 90% effective dose of propofol combined with oliceridine or fentanyl for inhibiting the insertion response in upper gastrointestinal endoscopy: a dose-finding trial [PDF]

Frontiers in Medicine
BackgroundPropofol combined with opioids is commonly used for procedural sedation, enhancing patient tolerance and reducing the incidence of adverse events. This study aimed to determine the 90% effective dose (ED90) of propofol combined with fentanyl or
